Description
Technical field
The present invention relates to the communications field, especially relate to collocation method and the device of a kind of hybrid automatic repeat-request (HybridAutomaticRepeatRequest, referred to as HARQ) buffer area.
Background technology
High-speed slender body theory (HighSpeedDownlinkPacketAccess, referred to as HSDPA) and evolution function, as two carrier wave (DualCarrier, referred to as DC), two-band-bis-carrier wave (DualBand-DualCarrier, referred to as DB-DC), multiple-input and multiple-output (MultipleInputMultipleOutput, referred to as MIMO) etc. function greatly improve peak rate and the throughput of network, to strengthen and the network that improves user is experienced.But the network frequency resource requirement of the technology such as DC to operator is harsher, the adjacent frequency of same frequency range etc. is needed to require also limit the application of DC; Simultaneously, because HSDPA does not have soft handover function, poor-performing when HSDPA user is in cell edge, when HSDPA user is in Zone switched, if the HSDPA resource of multiple community can be utilized simultaneously, then not only can improve the experience of user to a great extent, the utilance of Internet resources can also be improved further, improve the average throughput of network.For this reason, third generation partner program (3rdGenerationPartnershipProject, referred to as 3GPP) introduce the shared grouping access of multithread-high-speed downstream (MultiFlow-HSDPA, referred to as MF-HSDPA) technology at R11 version.MF-HSDPA technology refers to that two high speed descending sharing channels (HighSpeedDownlinkSharedChannel, referred to as HS-DSCH) being positioned at same frequency are simultaneously to the data block that same MF-HSDPA user scheduling is different.Use the user of multithread technology can receive at most the HS-DSCH transmission channel of 4 communities simultaneously, each community is according to its functional role, be defined as respectively: service high-speed shares down channel community (servingHS-DSCHCell), assistant service shares down channel community (AssistingservingHS-DSCHCell) at a high speed, auxiliary service high-speed shares down channel community (secondaryservingHS-DSCHCell), and auxiliary auxiliary service high-speed shares down channel community (AssistingsecondaryservingHS-DSCHCell).Wherein, servingHS-DSCHCell and secondaryservingHS-DSCHCell is two carrier cells, AssistingservingHS-DSCHCell and AssistingsecondaryservingHS-DSCHCell is two carrier cells; AssistingservingHS-DSCHCell and servingHS-DSCHCell frequency is identical, and AssistingsecondaryservingHS-DSCHCell and secondaryservingHS-DSCHCell frequency is identical.Two HS-DSCH channels on identical frequency can be positioned at same NodeB (Node B) or different N odeB, i.e. two kinds of shunt modes of corresponding MF-HSDPA: in base station between (intra-NodeB) and base station (inter-NodeB).For intra-NodeB pattern, protocol model as shown in Figure 1, downlink data shunting is positioned at high speed descending sharing channel and strengthens medium education (MediaAccessControlenhancedHS-DSCH, referred to as MAC-ehs) layer, a MAC-ehs entity is shared when data send, MAC-ehs entity supports 4 HS-DSCH transmission channels, and each HS-DSCH channel has corresponding up-downgoing signaling and HARQ (hybrid automatic repeat-request) entity separately.For inter-NodeB pattern, protocol model as shown in Figure 2, downlink data shunting is positioned at wireless spread-spectrum technology (RadioLinkControl, referred to as RLC) layer, use two MAC-ehs entities to be used for data to send, each MAC-ehs entity supports two HS-DSCH transmission channels, and each HS-DSCH channel has corresponding up-downgoing signaling and HARQ entity separately.
MF-HSDPA, as an evolution function of HSDPA, for reducing time delay and increasing the speed of retransmission data, still adopts the HARQ technology in HSDPA.HARQ refers to that recipient in case the decoding was unsuccessful, preserve the data received, and require transmit leg data retransmission, the data of re-transmission and previously received data carry out combining by recipient (if can not correctly demodulation out, need pre and post carrying out to merge the effect realizing a grand diversity).HARQ technology can improve systematic function, and can adjust the speed of effective code element neatly, can also compensate the error code owing to adopting link adaptation to bring.Recipient, in order to preserve data, needs to arrange HARQ memory field, and for subscriber equipment (UserEquipment, referred to as UE), in order to save cost, internal memory is all very valuable, needs rationally to arrange HARQ memory field according to system configuration.For inter-NodeB pattern, UE has two MAC-ehs entities, servingHS-DSCHCell and secondaryservingHS-DSCHCell belongs to a NodeB, share a MAC-ehs entity, AssistingservingHS-DSCHCell and AssistingsecondaryservingHS-DSCHCell belongs to a NodeB and shares a MAC-ehs entity, because the HARQ configuration of different NodeB is different, and current Uu (UE-UTRAN) mouth message lacks the HARQ memory configurations data of AssistingservingHS-DSCHCell and AssistingsecondaryservingHS-DSCHCell, such radio network controller (RadioNetworkController, referred to as RNC) just cannot configure the HARQ information of assisted cell for UE, thus cause MF-HSDPA technology to be applied.
For the problems referred to above in correlation technique, there is no solution effectively.
