The signal transmission method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

As shown in fig. 2, the present embodiment provides a signal transmission method, which may be applied to a terminal, and includes the following step 201.

In step 201, the terminal performs a first operation when there is an overlapping resource between the first resource of the first RS and the second resource of the first PDSCH.

Wherein the first operation may include at least one of:

performing punching or rate matching on the overlapped resources, and receiving a first PDSCH on resources except the overlapped resources in the second resources;

the first RS is not received.

Optionally, in this embodiment of the present application, the first resource may be indicated to the terminal by the network side device through configuration information, and the second resource may be indicated to the terminal by the network side device through paging downlink control information (paging DCI).

Optionally, in this embodiment of the present application, the overlapping resource may include at least one Resource Element (RE).

In this embodiment, for the above-mentioned "performing puncturing or rate matching on the overlapping resources and receiving the first PDSCH on the resources other than the overlapping resources in the second resources", the terminal may receive the first RS on the first resources (including the overlapping resources) or may not receive the first RS. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.

Accordingly, for the above-described "not to receive the first RS", the terminal may receive the first PDSCH or may not receive the first PDSCH. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.

Alternatively, in the embodiment of the present application, the "not receiving the first RS" may include two possible cases, which are the following case one and case two, respectively. These two cases are described below as examples.

The first condition is as follows: the first RS is not received on the overlapping resources.

It is to be understood that, in case one, the terminal may receive the first RS on a resource other than the overlapping resource among the first resources.

Case two: the first RS is not received on the first resource.

It can be understood that, in case two, the terminal does not receive all the first RSs transmitted by the network side device on the first resources.

Optionally, in this embodiment of the present application, the first RS may include at least one of:

RS configured by system information;

RS configured by Radio Resource Control (RRC) release (release) signaling;

RS for transmission is indicated by the paging DCI;

the transmitted RS is indicated by Paging Early Indication (PEI) information.

Optionally, in this embodiment of the present application, the first RS may be a CSI-RS or a Positioning Reference Signal (PRS).

Optionally, in this embodiment, the CSI-RS may be a resource set, where the resource set includes multiple CSI-RS resources, and the multiple CSI-RS resources may constitute (or constitute) a Tracking Reference Signal (TRS).

In this embodiment, the terminal does not receive the first RS, that is, the terminal assumes that the network does not send the first RS, that is, when the first RS and the first PDSCH resource overlap, the resource is preferentially used for transmission of the PDSCH, so that the terminal can obtain better receiving performance.

And determining whether to perform puncturing or rate matching reception in the overlapped resources according to the information whether the first RS is transmitted or not, which is indicated by the Paging DCI or the PEI or the RRC release message, so that the terminal can dynamically determine the method for receiving the PDSCH according to the information. If the first RS is not indicated to be sent, when the PDSCH is received, the corresponding resources are not punched or rate matched, more resources are used for PDSCH transmission, and the transmission performance of the PDSCH is favorably improved; and if the first RS is indicated to be sent, the corresponding resources are punched or subjected to rate matching, so that the phenomenon that the PDSCH receiving performance is reduced because the first RS resources are received as PDSCH resources is avoided.

Optionally, in this embodiment of the present application, the first PDSCH may include at least one of the following:

a PDSCH scheduled by a Physical Downlink Control Channel (PDCCH) scrambled by a paging radio network temporary identifier (P-RNTI);

a PDCCH-scheduled PDSCH scrambled by a random access radio network temporary identifier (RA-RNTI);

a PDCCH-scheduled PDSCH scrambled by a temporary cell radio network temporary identity (TC-RNTI);

a PDSCH scrambled by a message B radio network temporary identity (MSG-B-RNTI);

a PDSCH scrambled by a system information radio network temporary identity (SI-RNTI);

PDSCH of Multicast Broadcast Services (MBS);

terminal-specific PDSCH.

Optionally, in this embodiment of the present application, in a case that the first PDSCH includes a PDSCH scrambled by an SI-RNTI, the first PDSCH may be transmitted by a System Information Block (SIB) -X. Wherein X is an index of the system information block, and X is an integer greater than 1.

Optionally, in this embodiment of the present application, the terminal-specific PDSCH includes at least one of a dynamically scheduled PDSCH and a semi-persistent scheduling (SPS) PDSCH.

Optionally, in this embodiment of the present application, the first PDSCH may be used to transmit at least one of the following:

system information;

a paging message;

random Access Response (RAR) information;

message (MSG) B;

contention resolution information;

multicast Broadcast Service (MBS).

Optionally, in this embodiment of the present application, the contention resolution information may be MSG 4.

Optionally, in this embodiment of the application, when the first RS is an RS indicated by a paging DCI for transmission or an RS indicated by PEI information for transmission, the first operation may be to puncture overlapping resources and receive the first PDSCH on resources other than the overlapping resources in the second resources.

Optionally, in this embodiment of the application, when the first RS is an RS indicated by a paging DCI for transmission or an RS indicated by PEI information for transmission, the first operation may be to perform rate matching on overlapping resources and receive the first PDSCH on resources other than the overlapping resources in the second resources.

Optionally, in this embodiment of the present application, the terminal may satisfy a first condition, where the first condition may include at least one of:

supporting receiving PEI;

supporting receiving a first RS;

supporting the punching of the resource of the first RS;

supporting rate matching of resources of the first RS;

a specific type of terminal;

a terminal of a specific Identifier (ID);

a terminal listening to a specific Paging Occasion (PO).

Optionally, in this embodiment of the present application, the specific type of terminal may be a Rel-17 or higher version terminal.

In the embodiment of the application, since the old version of the terminal does not support receiving the first RS in idle or inactive state, the overlapping transmission condition cannot be processed, corresponding behavior is executed on the UE meeting the conditions, the influence of the corresponding network side device sending behavior on the existing terminal can be avoided, and the flexibility of the network is improved. For example, the network side device may configure a terminal satisfying the condition as a specific UE-ID, a paging PDSCH of the UE-ID may overlap with the first RS, and the UE may perform a processing manner of rate matching and puncturing when receiving the first PDSCH and the first RS. Under the condition that the first PDSCH transmission and the first RS transmission cannot be avoided from overlapping, the network side device may preferentially overlap the first RS and the first PDSCH of the UE that satisfies the condition, and avoid the influence on the transmission performance of the terminals due to the overlap with the first PDSCH of the terminal of the old version.

The signal transmission method provided by the embodiments of the present application is further exemplarily described below in two possible embodiments.

Example 1: if there are overlapping resources of the first resource of the first CSI-RS and the second resource of the first PDSCH, the terminal may perform at least one of: performing puncturing or rate matching on REs of the first CSI-RS overlapped with the first PDSCH resources, and receiving the first PDSCH; or not receiving the first CSI-RS (equivalent to the CSI-RS not being transmitted).

The puncturing of REs of the first CSI-RS may be understood as: when receiving the first PDSCH, acquiring symbols of the PDSCH from time-frequency resources and detecting, and assuming that a first PDSCH mapping mode of CSI-RS does not exist in the time-frequency resources. Further, the terminal may discard the received modulation symbols on the REs of the overlapping CSI-RSs therein after receiving the PDSCH on the time-frequency resources of the allocated PDSCH.

And performing rate matching on REs of the CSI-RS, namely when receiving the PDSCH, acquiring symbols of the PDSCH from time-frequency resources and detecting, and assuming that a first PDSCH mapping mode of the CSI-RS does not exist in the resources, namely the PDSCH is not mapped to the overlapped CSI-RS resources. The terminal receives the PDSCH on a resource other than the overlapped CSI-RS resource and demodulates the PDSCH.

The first PDSCH may be a PDSCH for transmitting system information, paging message, RAR, MSG B, MSG4 (contention resolution information), or multicast broadcast service.

Optionally, in a case that the network side device indicates the first CSI-RS transmission through the paging DCI or the PEI, the terminal performs puncturing or rate-matched PDSCH reception.

Example 2: and for the paging PDSCH reception of the terminal meeting the specific condition, the first CSI-RS of the overlapped resources are received by using a rate matching or puncturing mode. The ID of the terminal is the UE-ID satisfying a specific condition (for example, the UE-ID is: 5G-S-TMSI mod 1024), or the PO (paging occasion) monitored by the terminal is a specific PO.

Illustratively, the index of the above specific PO may be determined according to the following manner: i _ s = floor (UE _ ID/N) mod Ns, where i _ s is the index of PO; n is the total paging frame (paging frame) number in the preset time length; ns is the number of POs in one paging frame.

Optionally, in this embodiment of the present application, the specific ID may be configured by a network side device. For example, the network side device configures a value X, and the terminal may determine, according to the UE-ID, whether mod (UE _ ID, n) = X is satisfied or not, and if so, may determine that the ID of the terminal is a specific ID, so that the terminal may perform a corresponding operation.

Optionally, in this embodiment of the present application, the specific PO may be configured by a network side device. For example, the network side device configures i _ s (PO index) to a predetermined value, and the terminal may determine whether matching with the predetermined i _ s is satisfied (i.e., whether paging message reception is performed on the PO) according to the UE-ID, and if matching, may determine that the PO monitored by the terminal is a specific PO, so that the terminal may perform a response operation.

The network side device may configure the ID of some terminals as a specific UE-ID, so that the UE-ID receives the paging message on the PO. Alternatively, the terminals may satisfy the first condition described above. For such terminals, the terminal may puncture or rate-match the overlapping resources according to the configuration information of the first CSI-RS, thereby receiving the first PDSCH. Or, in the case that the first PDSCH and the first CSI-RS have at least one RE overlapping, the terminal may not receive the first CSI-RS, that is, the terminal assumes that the first CSI-RS is not transmitted.

In the embodiment of the present application, when there are overlapping resources in the first resource of the first RS and the second resource of the first PDSCH, the terminal may perform PDSCH reception by performing the first operation (performing puncturing or rate matching on the overlapping resources and receiving the first PDSCH on a resource other than the overlapping resources in the second resource and/or not receiving the first RS), so as to avoid an influence on PDSCH transmission caused by RS transmission.

As shown in fig. 3, an embodiment of the present application provides a signal transmission method, which may be applied to a network side device, and the method may include step 301 described below.

Step 301, the network side device performs a second operation when there is an overlapping resource between the first resource of the first RS and the second resource of the first PDSCH.

Wherein the second operation may include at least one of:

performing punching or rate matching on the overlapped resources, and transmitting a first PDSCH on resources except the overlapped resources in the second resources;

the first RS is not transmitted.

It should be noted that, in this embodiment of the present application, for the above-mentioned "performing puncturing or rate matching on overlapping resources, and sending the first PDSCH on resources other than the overlapping resources in the second resource", the network side device may send and receive the first RS on the resources other than the overlapping resources in the first resource, or may not send the first RS. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.
