Description

Information processing method, terminal, base station and system
Technical Field
The present invention relates to the field of communications, and in particular, to an information processing method, terminal, base station, and system.
Background
UMTS (Universal Mobile Telecommunications System), is one of the global 3G standards set by the international organization for standardization 3GPP (3rd Generation Partnership Project). WCDMA (Wideband Code Division Multiple Access) is one of the mainstream technologies of the third generation mobile communication system, and is applied to the Release-5 version of UMTS, and a High Speed Downlink Packet Access (HSDPA) technology is introduced into the Release-5 version to improve the Downlink data transmission rate and reduce the user data transmission delay, so that the user has better experience in the UMTS network.
When the Physical layer of the HSDPA technology works, a NodeB (base station) transmits data to a UE (User Equipment) through an HS-PDSCH (High-Speed Physical Downlink Shared Channel) of the Physical layer, and simultaneously transmits Control signaling and the like related to the HS-PDSCH through an HS-SCCH (High-Speed Shared Control Channel); after receiving the HS-SCCH, the UE demodulates, decodes, etc. the HS-PDSCH by using the control information carried thereon, and then the UE generates ACK (Acknowledgement, decoding correct information)/NACK (Non-Acknowledgement, decoding incorrect information)/DTX (discontinuous Transmission) according to the HS-SCCH reception condition and whether the HS-PDSCH is decoded correctly or not, which can be used to refer to information that data is not detected in the present application; in addition, the UE also measures a downlink Channel condition, generates CQI (Channel Quality Indicator) information, and the UE carries the ACK/NACK/DTX information and the CQI information on the HS-DPCCH Channel and sends the information to the NodeB, which uses information fed back according to the UE as a basis for service scheduling. In MF-Tx (multi-flow Transmission), the UE needs to feed back data from multiple cells, and may jointly encode feedback information (ACK/NACK/DTX and CQI and/or PCI (Precoding Control Indication)) of the multiple cells on one HS-DPCCH channel for feedback.
In the prior art, when ACK/NACK joint coding is performed on feedback information of two cells in a DC-HSDPA (Dual Carrier/Cell HSDPA, two-Carrier/Cell high speed downlink packet access) and DC-MIMO (Dual Carrier/Cell MIMO, Multiple Input Multiple Output), and two-Carrier or two-Cell Multiple Input Multiple Output) scenario, a UE obtains w by looking up a table according to a receiving condition of the two cells0，w1，...w9(which may be referred to as a codeword) and then mapped to a corresponding ACK/NACK field (e.g., one slot) of the HS-DPCCH according to a mapping relationship preset in ACK/NACK joint coding of DC-HSDPA and DC-MIMO. Two paired cells, i.e. two cells participating in joint coding (including the case that both cells are active cells, or one cell is an active cell and one cell is a deactivated cell), are used in the coding process of HARQ (Hybrid Automatic Repeat Request) -ACKThe coding table is not based on the optimization criterion that the minimum code distance of all code words in the HARQ-ACK full codebook space (as shown in FIG. 3, all codebooks in the whole codebook) is as large as possible, but is based on the optimization criterion that the minimum code distance of all code words in each HARQ-ACK subspace is as large as possible.
In the process of implementing the invention, the inventor finds that the prior art has at least the following problems:
in MF-Tx, using the cooperation among a plurality of cells in a NodeB or the cooperation among a plurality of cells in a NodeB to send different data to a UE, when one of the cells participating in MF-Tx configures MIMO and multiplexes a DC-MIMO code book or a 3C-MIMO (3Carrier/Cell HSDPA, three-Carrier or three-Cell multiple input multiple output) code book or a 4C-HSDPA (4Carrier/Cell HSDPA, four-Carrier or four-Cell high speed downlink packet access) code book or a 4C-MIMO (4Carrier/Cell HSDPA, four-Carrier or four-Cell multiple input multiple output) code book, for inter-MF-Tx (i.e. all cells belong to two or more NodeB instead of the same NodeB), because all cells do not belong to the same NodeB, there is no communication mechanism between NodeB at present, that is, the data scheduling transmission condition between the cells under two nodebs cannot be shared, so when one cell detects ACK/NACK/DTX of the cell, the state of the other cell is unknown, and at this time, a search is performed for the condition that the other cell is single-stream or double-stream, that is, a search needs to be performed in two codebook subspaces, where a decoding space (or referred to as a decision space) is two subspaces, and the HARQ-ACK decoding performance becomes very poor because the cells in the two nodebs cannot determine the HARQ-ACK codebook subspace.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In order to facilitate understanding of the technical aspects of the present invention, the related art related to the present invention will be described below.
In the UMTS protocol, the principle of the DC-HSDPA technology is that when a UE initiates a service in an area covered by one dual cell, the network side can configure the UE as DC-HSDPA, and at this time, the UE can receive HSDPA services in two cells at the same time, so that the peak rate is improved. In DC-HSDPA, two cells are required to be adjacent, downlink timing is the same, and the two cells must be in the same NodeB and have the same coverage characteristics (as shown in fig. 1, a first cell and a second cell are both under a base station, working frequency points are the relationship of adjacent frequency points, coverage of the two cells can be considered to be the same, the first cell is a primary cell, and the second cell is a secondary cell). The MIMO (Multiple Input Multiple Output) is divided into two modes, namely a single-stream mode and a double-stream mode, where the single-stream mode refers to that only one data block is transmitted to one UE by one cell at each transmission time, and the double-stream mode refers to that two data blocks are transmitted to one UE by one cell at each transmission time. Subsequently, DC-MIMO (Dual Carrier/Cell MIMO, two-Carrier or two-Cell multiple input multiple output), 3C-HSDPA (3Carrier/Cell HSDPA, three-Carrier or three-Cell high speed downlink packet access), 3C-MIMO (3Carrier/Cell HSDPA, three-Carrier or three-Cell multiple input multiple output), 4C-HSDPA (4Carrier/Cell HSDPA, four-Carrier or four-Cell high speed downlink packet access), 4C-MIMO (4Carrier/Cell HSDPA, four-Carrier or four-Cell multiple input multiple output), and the like are successively introduced into the UMTS protocol to increase the peak rate.
In MF-Tx, using the cooperation among multiple cells in a NodeB or the cooperation among multiple cells in multiple nodebs to send different data to a UE, the MF-Tx may be regarded as an extension of multi-carrier/multi-Cell technology in a protocol, and is divided into two major scenarios, i.e., intra-NodeB (all cooperating cells belong to one NodeB) and inter-NodeB (all cooperating cells do not belong to one NodeB) according to whether all cooperating cells belong to one NodeB or not (see fig. 2, taking two cells as an example, the working frequency/carrier of a first Cell and a second Cell may be the same or different, the first Cell is a primary Cell (Serving Cell)/a primary Serving Cell (Prim Assisted Cell)/an Assisted Cell (Assisted Cell)), the second Cell is a Secondary Cell (Serving Cell)/an Assisted Cell (Assisted Cell)), fig. 2a shows that all cooperative cells belong to one base station, i.e. intra-NodeB, and fig. 2b shows that all cooperative cells belong to two or more nodebs, i.e. inter-NodeB. In practice, it can be further subdivided into multiple scenarios according to the number of carriers and cells, such as SF-DC (Single Frequency Dual Cell), DF-4C (Dual Frequency 4Cell, Dual carrier four Cell), and DF-DC (Dual Frequency Dual Cell, Dual carrier Dual Cell).
DC-MIMO (including the case where one cell is deactivated in DC-MIMO) uses the codebook used by Table 1 for the DC-MIMOACK/NACK/DTX joint coding scheme, and 3C-MIMO/4C-HSDPA/4C-MIMO each uses Table 1 as the codebook used by the ACK/NACK/DTX joint coding scheme.

when the feedback information of the cell is ACK _ NACK, mapping the ACK _ NACK into ACK _ NACK, wherein the ACK _ NACK is the information that the decoding of one data block is correct and the decoding of one data block is wrong under a double-flow mode, namely AN → AN;
when the feedback information of the cell is NACK _ ACK, the NACK _ ACK is mapped into NACK _ ACK, and the NACK _ ACK is information that one data block is decoded incorrectly and one data block is decoded correctly in a double-stream mode, namely NA → NA;

Further, in the first mapping relationship, when the feedback information of the cell received by the UE is ACK or the feedback information of the cell received by the UE is NACK, other mapping relationships may be used, as long as the single stream is mapped into the dual stream. If the second mapping relationship is preset, when the feedback information of the cell is ACK, mapping the ACK to ACK _ NACK or to NACK _ ACK, i.e. a → AN, a → NA; when the feedback information of the cell is NACK, the NACK is mapped to NACK _ ACK or to ACK _ NACK, i.e., N → NA, N → AN, etc. However, when the feedback information of the cell received by the UE is ACK _ ACK, NACK _ NACK, ACK _ NACK, NACK _ ACK, or DTX, the mapping relationship is still the same as the first mapping relationship, and details thereof are not described here.
Regardless of the mapping relationship, after mapping the feedback information according to the mapping relationship, the mapping method is actually equivalent to space folding, i.e. all four subspaces (subspaces 1-4) are folded into one subspace (subspace 4), as shown in fig. 6, one subspace is within one circle, subspace 1: primary Cell Single/DTX + Secondary Cell Single/DTX; the subspace 2: primary Cell Dual stream (Serving Cell Dual)/DTX + Secondary Cell Single stream (Secondary Cell Single)/DTX; subspace 3: primary Cell Single)/DTX + Secondary Cell Dual/DTX; the subspace 4: primary Cell Dual stream (Serving Cell Dual)/DTX + Secondary Cell Dual stream (Secondary Cell Dual)/DTX.
The codebook space after the above mapping or spatial folding is shown in table 2, and it can be seen that it is only one subspace of fig. 3.
