In order to solve the problem that in a communication scene of a passive internet of things (Passive IoT Networks, PIoT), signals transmitted by a reader are easily interrupted and cannot be continuously transmitted, a wireless communication method and device, a resource configuration method and device, and a reader, a tag and network side equipment are provided in the embodiments of the present application.

Fig. 2A shows a block diagram of a PIoT wireless communication system to which embodiments of the present application are applicable. The PIoT wireless communication system includes a network-side device 21 and a Tag (Tag) 22. In this application scenario, the network side device 21 acts as a reader (reader), and sends a control command (command) or Continuous Wave (CW) signal to the tag 22, where the network side device 21 may be a Base station (Base station); the Tag 22 may be a backscatter communication (Backscatter Communication, BSC) device and the Tag 22 with backscatter communication capability may return a backscatter signal (e.g., tag reply) to the network side device 21.

A communication method provided in the embodiments of the present application is described below.

As shown in fig. 3, a communication method provided in an embodiment of the present application may include:

step 301, the reader determines at least one target frequency domain resource, wherein time domain resources corresponding to the at least one target frequency domain resource are continuous.

Step 302, the reader transmits a first signal on the at least one target frequency domain resource.

Wherein the first signal may include, but is not limited to, at least one of the following:

(1) Carrier (Carrier) or Continuous Wave (CW);

(2) Control commands (command);

(3) Wake-up signal.

When the first signal is a carrier wave or a continuous wave, the tag may modulate the received carrier wave or continuous wave after receiving the carrier wave or continuous wave to obtain a backscatter signal.

In general, information transfer between a reader and a tag runs through three processes of selection (Select), inventory (Inventory), and Access (Access).

Select (Select): an interrogation module (reader) in the reader selects a population of tags for a subsequent Inventory (Inventory) or cryptographically challenges (Challenge) the population of tags for a subsequent authentication process, the commands in the selection process including a selection command and a Challenge command.

Inventory (Inventory): a process for identifying tags by an interrogation module (interactor). The Query module begins inventory tags by sending a Query command (Query command) in one of four sessions. One or more tags may reply to the interrogation module. The interrogation module detects a reply of a single tag and requests at least one of its Protocol Control (PC) field, optional extended Protocol Control (extended Protocol Control, XPC) field, evolved packet core (Evolved Packet Core, EPC) field, and cyclic redundancy check-16 (Cyclic Redundancy Check, CRC-16) from the tag. A roulette point is only running in one session at a time. A single inventory may contain multiple control commands.

Access (Access): the process by which the interrogation module interacts (reads, writes, verifies, or otherwise interacts) with a single tag. The interrogation module individually identifies and uniquely identifies the tag prior to access. The access may also include a plurality of control commands.

Specifically, the operation command and the control command transmitted from the reader to the tag in the above three processes may refer to table 1 and table 2, respectively.

Table 1 operation command of reader

TABLE 2 control command for reader

(4) The frequency offset between different target frequency domain resources may be in Hz or Resource Block (RB) units.

In the case that the configuration information of the at least one target frequency domain resource includes time domain information of a time domain resource corresponding to the at least one target frequency domain resource, and the time domain information includes a duration, the duration may include, but is not limited to, at least one of:

(1) A duration of transmitting the first signal on the at least one target frequency domain resource;

(2) Switching time for switching between different target frequency domain resources;

Further, the reader is full duplex capable during a first period of time, wherein the first period of time is a period of time during which the reader receives a second signal from a tag.
