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

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

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

Wherein the first operation may include at least one of:

punching or rate matching is carried out on the overlapped resources, and a first PDSCH is received on the resources except the overlapped resources in the second resources;

The first RS is not received.

Optionally, in the 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 downlink control information, PAGING DCI).

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

In the embodiment of the present application, the "puncture or rate match is performed on the overlapping resources and the first PDSCH is received on the resources other than the overlapping resources in the second resources" may or may not receive the first RS on the first resources (including the overlapping resources). The method can be specifically determined according to actual use requirements, and the embodiment of the application is not limited.

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

Alternatively, in the embodiment of the present application, the above "not receiving the first RS" may include two possible cases, namely, the following case one and the following case two. These two cases are each exemplified below.

Case one: the first RS is not received on the overlapping resources.

It will be appreciated that in case one, the terminal may receive the first RS on resources other than the overlapping resources among the first resources.

And a second case: the first RS is not received on the first resource.

It can be appreciated that in case two, the terminal does not receive all the first RSs sent by the network side device on the first resource.

Optionally, in an 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 (radio resource control, RRC) release (release) signaling;

An RS indicated by PAGING DCI to transmit;

the transmitted RS is indicated by paging advance indication (PEI) information.

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

Alternatively, in the embodiment of the present application, the CSI-RS may be a set of resources, where the set of resources includes multiple CSI-RS resources, and the multiple CSI-RS resources may form (or compose) a tracking reference signal (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 transmit the first RS, that is, when the first RS and the first PDSCH resources overlap, the resources are preferentially used for PDSCH transmission, so that the terminal may obtain better reception performance.

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

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

PDSCH scheduled by physical downlink control channel (physical downlink control channel, PDCCH) scrambled by paging radio network temporary identity (paging radio network temporary identifier, P-RNTI);

PDSCH scheduled by PDCCH scrambled by random access radio network temporary identity (random ACCESS RNTI, RA-RNTI);

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

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

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

PDSCH of multicast broadcast service (multicast broadcast services, MBS);

Terminal-specific PDSCH.

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

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

system information;

Paging messages;

Random access response (random access response, RAR) information;

message (MSG) B;

Competition resolving information;

multicast Broadcast Service (MBS).

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

Optionally, in the embodiment of the present application, in a case where the first RS is an RS indicated by PAGING DCI to transmit or an RS indicated by PEI information to transmit, the first operation may be puncturing overlapping resources, and receiving the first PDSCH on resources other than the overlapping resources in the second resources.

Optionally, in the embodiment of the present application, in a case where the first RS is an RS indicated by PAGING DCI to transmit or an RS indicated by PEI information to transmit, the first operation may be rate matching overlapping resources, and receive the first PDSCH on resources other than the overlapping resources in the second resources.

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

support to receive PEI;

Support reception of the first RS;

Supporting punching of resources 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);

terminals listening for specific Paging Opportunities (POs).

Alternatively, in the embodiment of the present application, the specific type of terminal may be Rel-17 or higher.

In the embodiment of the application, the old version terminal does not support receiving the first RS in the idle or inactive state, so that the situation of overlapping transmission cannot be processed, the corresponding behavior is executed for the UE meeting the condition, the influence of the corresponding network side equipment 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 the terminal satisfying the condition as a specific UE-ID, and paging PDSCH of these UE-IDs may overlap with the first RS, so that when receiving that the first PDSCH overlaps with the first RS, these UEs may perform a rate matching and puncturing processing manner. When the first PDSCH transmission and the first RS transmission cannot be avoided overlapping, the network side device may preferentially overlap the first RS and the first PDSCH of the UE meeting the conditions, so as to avoid the influence on the transmission performance of the terminals caused by overlapping the first PDSCH of the old terminal.

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

Example 1: if there is an overlapping resource between the first resource of the first CSI-RS and the second resource of the first PDSCH, the terminal may perform at least one of: punching or rate matching is carried out on RE of the first CSI-RS overlapped with the first PDSCH resource, and the first PDSCH is received; or does not receive the first CSI-RS (equivalent to CSI-RS not being transmitted).

The above puncturing of REs of the first CSI-RS may be understood as: when the first PDSCH is received, symbols of the PDSCH are acquired from the time-frequency resource and detected, it is assumed that the first PDSCH mapping mode of the CSI-RS does not exist in the time-frequency resource. Further, the terminal may discard received modulation symbols on REs of overlapping CSI-RSs therein after receiving PDSCH on time-frequency resources of the allocated PDSCH.

And performing rate matching on REs of the CSI-RS, namely acquiring symbols of the PDSCH from time-frequency resources and detecting when the PDSCH is received, wherein a first PDSCH mapping mode of the CSI-RS does not exist in the resources, namely the PDSCH is not mapped to the resources of the overlapped CSI-RS. And the terminal receives and demodulates the PDSCH on resources except for the overlapped CSI-RS resources.

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

Example 2: for PAGING PDSCH reception of a terminal satisfying a specific condition, the first CSI-RS of the overlapping resource is received using a rate matching or puncturing manner. The terminal' S ID is a UE-ID that satisfies a specific condition (e.g., the UE-ID is 5G-S-TMSI mod 1024), or the PO (paging occasion) the terminal listens to is a specific PO.

Illustratively, the index of the particular PO may be determined according to the following: 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 duration; ns is the number of POs in one paging frame.

Alternatively, in the embodiment of the present application, the specific ID may be configured by a network side device. For example, the network side device configures the value X, and the terminal may determine whether the UE-ID satisfies mod (ue_id, n) =x according to the UE-ID, and if so, may determine that the ID of the terminal is a specific ID, so that the terminal may perform a corresponding operation.

Alternatively, in the 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, the terminal may determine whether the i_s matches the predetermined i_s (i.e., determine whether to perform paging message reception on the PO) according to the UE-ID, and if so, 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 a part of the terminals as a specific UE-ID so that the UE-ID performs reception of 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 overlapping resources according to the configuration information of the first CSI-RS, thereby receiving the first PDSCH. Or when at least one RE of the first PDSCH and the first CSI-RS overlaps, the terminal may not receive the first CSI-RS, that is, it is equivalent to the terminal assuming that the first CSI-RS are not transmitted.

In the embodiment of the application, under the condition that the first resource of the first RS and the second resource of the first PDSCH have overlapped resources, the terminal can perform PDSCH reception by executing the first operation (punching or rate matching on the overlapped resources and receiving the first PDSCH on the resources except the overlapped resources in the second resources and/or not receiving the first RS), thereby avoiding the influence on the transmission of the PDSCH caused by the transmission of the RS.

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 the following step 301.

Step 301, the network side device executes 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:

Punching or rate matching is carried out on the overlapped resources, and a first PDSCH is sent on the resources except the overlapped resources in the second resources;

the first RS is not transmitted.

In the embodiment of the present application, the "puncturing or rate matching is performed on the overlapping resources and the first PDSCH is transmitted on the resources except for the overlapping resources in the second resources" may or may not transmit the first RS on the resources except for the overlapping resources in the first resources.
