Abstract

Claims (39)

1 . A method comprising:

transmitting, by a terminal, to a base station, terminal capability information related to antenna switching;

receiving, by the terminal, from the base station, configuration information related to a sounding reference signal; and

transmitting, by the terminal, to the base station, the sounding reference signal based on the configuration information,

wherein the configuration information includes information on a plurality of sounding reference signal resource sets in which usage is configured for antenna switching,

wherein the configuration information includes information on antenna ports for one or more sounding reference signal resources included in each of the plurality of sounding reference signal resource sets,

wherein each of the plurality of sounding reference signal resource sets is transmitted in a different slot and all sounding reference signal resources in the plurality of sounding reference signal resource sets are transmitted during different sounding reference signal transmission occasions, and

wherein a time interval between slots in which the plurality of sounding reference signal resource sets are transmitted is configured so that the plurality of sounding reference signal resource sets are transmitted within a predetermined number of slots, and

wherein the same antenna port is configured for some sounding reference signal resources of all the sounding reference signal resources by the configuration information.

2 . The method of claim 1 , wherein the configuration information includes information on an antenna port group that is rotated for each sounding reference signal transmission occasion for each of the plurality of sounding reference signal resource sets.

3 . The method of claim 1 , wherein the information on antenna ports for the one or more sounding reference signal resources includes information on an antenna port group that is rotated for each sounding reference signal transmission occasion for the one or more sounding reference signal resources.

4 . The method of claim 1 , wherein spatial relation information for all sounding reference signal resources in the plurality of sounding reference signal resource sets or in each of the plurality of sounding reference signal resource sets is configured identically.

5 . The method of claim 1 , wherein based on the plurality of sounding reference signal resource sets being configured with a usage for partial reciprocity between downlink and uplink, the configuration information includes information on antenna ports for one or more sounding reference signal resources included in each of the plurality of sounding reference signal resource sets.

6 . The method of claim 1 , wherein based on the plurality of sounding reference signal resource sets being configured to correspond to m transmission and n reception, the configuration information includes information on antenna ports for one or more sounding reference signal resources included in each of the plurality of sounding reference signal resource sets, and

wherein m is an integer greater than 0, n is an integer equal to or greater than m, and n is not divisible by m.

7 . The method of claim 1 , wherein, for periodic sounding reference signal transmission or semi-persistent sounding reference signal transmission, different periods and offsets are configured for the plurality of sounding reference signal resource sets so that the plurality of sounding reference signal resource sets are transmitted in different slots.

8 . The method of claim 1 , wherein, for aperiodic sounding reference signal transmission, different slot offsets are configured for the plurality of sounding reference signal resource sets so that the plurality of sounding reference signal resource sets are transmitted in different slots.

9 . The method of claim 1 , wherein each of the plurality of sounding reference signal resource sets is related to a different panel of the terminal.

10 . A terminal comprising:

at least one transceiver for transmitting and receiving a wireless signal; and

at least one processor for controlling the at least one transceiver,

wherein the at least one processor configured to:

transmit, to a base station, terminal capability information related to antenna switching;

receive, from the base station, configuration information related to a sounding reference signal; and

transmit, to the base station, the sounding reference signal based on the configuration information,

wherein the configuration information includes information on a plurality of sounding reference signal resource sets in which usage is configured for antenna switching,

wherein the configuration information includes information on antenna ports for one or more sounding reference signal resources included in each of the plurality of sounding reference signal resource sets,

wherein each of the plurality of sounding reference signal resource sets is transmitted in a different slot and all sounding reference signal resources in the plurality of sounding reference signal resource sets are transmitted during different sounding reference signal transmission occasions, and

wherein a time interval between slots in which the plurality of sounding reference signal resource sets are transmitted is configured so that the plurality of sounding reference signal resource sets are transmitted within a predetermined number of slots, and

wherein the same antenna port is configured for some sounding reference signal resources of all the sounding reference signal resources by the configuration information.

11 . A method comprising:

receiving, by a base station, from a terminal, terminal capability information related to antenna switching;

transmitting, by the base station, to the terminal, configuration information related to a sounding reference signal; and

receiving, by the base station, from the terminal, the sounding reference signal based on the configuration information,

wherein the configuration information includes information on a plurality of sounding reference signal resource sets in which usage is configured for antenna switching,

wherein the configuration information includes information on antenna ports for one or more sounding reference signal resources included in each of the plurality of sounding reference signal resource sets,

wherein each of the plurality of sounding reference signal resource sets is transmitted in a different slot and all sounding reference signal resources in the plurality of sounding reference signal resource sets are transmitted during different sounding reference signal transmission occasions, and

wherein a time interval between slots in which the plurality of sounding reference signal resource sets are transmitted is configured so that the plurality of sounding reference signal resource sets are transmitted within a predetermined number of slots, and

wherein the same antenna port is configured for some sounding reference signal resources of all the sounding reference signal resources by the configuration information.
