Abstract

A signal sending and receiving method includes: receiving, by a terminal device, at least one piece of resource configuration information for determining N reference signal resource groups, and each of the N reference signal resource groups includes at least one reference signal resource; and sending a reference signal on a resource in an i th reference signal resource group in the N reference signal resource groups by using a j th antenna group corresponding to the i th reference signal resource group, where the j th antenna group includes at least one antenna. The N reference signal resource groups correspond to N antenna groups, and any two of the N antenna groups are different.

First claim

What is claimed is:

1. A signal receiving method, comprising:
sending at least one piece of resource configuration information for configuring at least one sounding reference signal (SRS) resource set, wherein each SRS resource set of the at least one SRS resource set comprises one or more SRS resources, and wherein different SRS resources comprised in a same SRS resource set occupy different symbols and correspond to different user equipment (UE) antenna ports; and
receiving an SRS on at least one SRS resource of the at least one SRS resource set;
wherein a guard period between two SRS resources in a same SRS resource set is greater than or equal to Y symbols, wherein the value of Y and a subcarrier spacing satisfy at least one of:
the value of Y is 1 and the subcarrier spacing is 15 kHz;
the value of Y is 1 and the subcarrier spacing is 30 kHz;
the value of Y is 1 and the subcarrier spacing is 60 kHz; or
the value of Y is 2 and the subcarrier spacing is 120 kHz.

2. The method according to claim 1 , wherein the method further comprises:
sending at least one piece of first information for indicating whether SRSs to be transmitted on all SRS resources in one SRS resource set are to be sent in an antenna switching manner.

3. The method according to claim 1 , wherein the method further comprises:
sending at least one piece of first information for indicating whether SRSs are used to measure a channel for antenna selection.

4. The method according to claim 1 , wherein the subcarrier spacing is a subcarrier spacing for the SRS, and wherein the value of Y is based on the subcarrier spacing for the SRS.

5. An apparatus, comprising:
one or more processors, and
a non-transitory storage medium configured to store program instructions;
wherein the program instructions, when executed by the one or more processors, facilitate:
sending, by the apparatus, at least one piece of resource configuration information for configuring at least one sounding reference signal (SRS) resource set, wherein each SRS resource set of the at least one SRS resource set comprises one or more SRS resources, and wherein different SRS resources comprised in a same SRS resource set occupy different symbols and correspond to different user equipment (UE) antenna ports; and
receiving, by the apparatus, an SRS on at least one SRS resource of the at least one SRS resource set;
wherein a guard period between two SRS resources in a same SRS resource set is greater than or equal to Y symbols, wherein the value of Y and a subcarrier spacing satisfy at least one of:
the value of Y is 1 and the subcarrier spacing is 15 kHz;
the value of Y is 1 and the subcarrier spacing is 30 kHz;
the value of Y is 1 and the subcarrier spacing is 60 kHz; or
the value of Y is 2 and the subcarrier spacing is 120 kHz.

6. The apparatus according to claim 5 , wherein the program instructions, when executed by the one or more processors, further facilitate:
sending, by the apparatus, at least one piece of first information for indicating whether SRSs to be transmitted on all SRS resources in one SRS resource set are to be sent in an antenna switching manner.

7. The apparatus according to claim 5 , wherein the program instructions, when executed by the one or more processors, further facilitate:
sending, by the apparatus, at least one piece of first information for indicating whether SRSs are used to measure a channel for antenna selection.

8. The apparatus according to claim 5 , wherein the subcarrier spacing is a subcarrier spacing for the SRS, and wherein the value of Y is based on the subcarrier spacing for the SRS.

9. A non-transitory computer-readable medium having program instructions stored thereon, wherein, the program instructions, when executed by a processor of a network device, facilitate:
sending at least one piece of resource configuration information for configuring at least one sounding reference signal (SRS) resource set, wherein each SRS resource set of the at least one SRS resource set comprises one or more SRS resources, and wherein different SRS resources comprised in a same SRS resource set occupy different symbols and correspond to different user equipment (UE) antenna ports; and
receiving an SRS on at least one SRS resource of the at least one SRS resource set;
wherein a guard period between two SRS resources in a same SRS resource set is greater than or equal to Y symbols, wherein the value of Y and a subcarrier spacing satisfy at least one of:
the value of Y is 1 and the subcarrier spacing is 15 kHz;
the value of Y is 1 and the subcarrier spacing is 30 kHz;
the value of Y is 1 and the subcarrier spacing is 60 kHz; or
the value of Y is 2 and the subcarrier spacing is 120 kHz.

10. The non-transitory computer-readable medium according to claim 9 , wherein the instructions, when executed by the processor of the network device, further facilitate:
sending at least one piece of first information for indicating whether SRSs to be transmitted on all SRS resources in one SRS resource set are to be sent in an antenna switching manner.

11. The non-transitory computer-readable medium according to claim 9 , wherein the instructions, when executed by the processor of the network device, further facilitate:
sending at least one piece of first information for indicating whether SRSs are used to measure a channel for antenna selection.

12. The non-transitory computer-readable medium according to claim 9 , wherein the subcarrier spacing is a subcarrier spacing for the SRS, and wherein the value of Y is based on the subcarrier spacing for the SRS.
