Method, device and computer readable medium for communication
Embodiments of the present disclosure relate to methods, devices and computer readable media for communication of a RS. A method of communication comprises determining, at a network device, information indicating a first number of resources configured for communication of a RS, the first number being associated with a third number of transmit antenna ports and a fourth number of receive antenna ports of a terminal device and the fourth number being larger than a predetermined number; and transmitting the information to the terminal device. The method further comprises receiving, at the terminal device, the information; determining a second number of resources from the first number of resources, the first number being larger than or equal to the second number; and performing the communication of the RS based on the second number of resources. Embodiments of the present disclosure can achieve a RS resource configuration and a RS communication for increased antenna ports.
1 . A method of communication performed by a terminal device, the method comprising:
receiving, from a network device, configuration information of up to two sounding reference signal (SRS) resource sets configured for antenna switching,
wherein the terminal device is configured with xT6R for antenna switching,
wherein x is a positive integer,
wherein each SRS resource set in the up to two SRS resource sets comprises two SRS resources transmitted in different symbols,
wherein each SRS resource consists of four SRS ports with SRS port 1003 disabled, and
wherein three SRS ports without port 1003 in each SRS resource are associated with different user equipment (UE) antenna ports; and
splitting a linear of a transmit power on an active uplink bandwidth part (UL BWP) of a carrier of a serving cell equally across the three SRS ports without the SRS port 1003 of each SRS resource.
2 . The method of claim 1 , wherein the up to two SRS resource sets comprise a first SRS resource set and a second SRS resource set, and
wherein the first SRS resource set and the second SRS resource set are configured with a different value of resource type.
3 . The method of claim 1 , wherein each SRS resource set comprises the two SRS resources and at least one SRS resource, the two SRS resources being the first two available SRS resources in each SRS resource set.
4 . The method of claim 3 , wherein a total number of SRS resources in each SRS resource set is larger than 6/x or is larger than ceil(6/x).
5 . A method of communication performed by a network device, the method comprising:
transmitting, to a terminal device, configuration information of up to two sounding reference signal (SRS) resource sets configured for antenna switching,
wherein the terminal device is configured with xT6R for antenna switching,
wherein x is a positive integer,
wherein each SRS resource set in the up to two SRS resource sets comprises two SRS resources transmitted in different symbols,
wherein each SRS resource consists of four SRS ports with SRS port 1003 disabled, and
wherein three SRS ports without port 1003 in each SRS resource are associated with different user equipment (UE) antenna ports, and
wherein a linear of a transmit power on an active uplink bandwidth part (UL BWP) of a carrier of a serving cell is split equally across the three SRS ports without the SRS port 1003 of each SRS resource.
6 . The method of claim 5 , wherein the up to two SRS resource sets comprise a first SRS resource set and a second SRS resource set, and
wherein the first SRS resource set and the second SRS resource set are configured with a different value of resource type.
7 . The method of claim 5 , wherein each SRS resource set comprises the two SRS resources and at least one SRS resource, the two SRS resources being the first two available SRS resources in each SRS resource set.
8 . The method of claim 7 , wherein a total number of SRS resources in each SRS resource set is larger than 6/x or is larger than ceil (6/x).
9 . A terminal device, comprising:
a processor configured to cause the terminal device to:
receive, from a network device, configuration information of up to two sounding reference signal (SRS) resource sets configured for antenna switching,
wherein the terminal device is configured with xT6R for antenna switching,
wherein x is a positive integer,
wherein each SRS resource set in the up to two SRS resource sets comprises two SRS resources transmitted in different symbols,
wherein each SRS resource consists of four SRS ports with SRS port 1003 disabled, and
wherein three SRS ports without port 1003 in each SRS resource are associated with different user equipment (UE) antenna ports; and
split a linear of a transmit power on an active uplink bandwidth part (UL BWP) of a carrier of a serving cell equally across the three SRS ports without the SRS port 1003 of each SRS resource.
10 . The terminal device of claim 9 , wherein the up to two SRS resource sets comprise a first SRS resource set and a second SRS resource set, and
wherein the first SRS resource set and the second SRS resource set are configured with a different value of resource type.
11 . The terminal device of claim 9 , wherein each SRS resource set comprises the two SRS resources and at least one SRS resource, the two SRS resources being the first two available SRS resources in each SRS resource set.
12 . The terminal device of claim 11 , wherein a total number of SRS resources in each SRS resource set is larger than 6/x or is larger than ceil(6/x).
