Abstract

A wireless communication method includes receiving, by a wireless communication device from a network, an indication of a candidate beam set comprising a first number of beam states; determining, by the wireless communication device, a second number of power-related information, each of which corresponds to a beam state in a reporting beam set determined based on the candidate beam set; and sending, by the wireless communication device to the network, a report comprising the power-related information, wherein at least one of the first number or the second number is a positive integer.

First claim

What is claimed:

1 . A wireless communication method, comprising:
receiving, by a wireless communication device from a network, an indication of a candidate beam set comprising a first number of beam states; determining, by the wireless communication device, a second number of power-related information, each of which corresponds to a beam state in a reporting beam set determined based on the candidate beam set; and sending, by the wireless communication device to the network, a report comprising the power-related information, wherein at least one of the first number or the second number is a positive integer.

2 . The method of claim 1 , wherein at least one of:
each of the second number of power-related information comprises a Maximum Permissible Exposure (MPE); or the candidate beam set is configured by a RRC signaling.

3 . The method of claim 1 , the reporting beam set is determined based on the candidate beam set comprising:
the reporting beam set is determined by an indication of a reporting beam set in the report.

4 . The method of claim 3 , wherein the reporting beam set is determined as the candidate beam set, in response to determining at least one of the following conditions is satisfied:
absence of the indication of a reporting beam set in the report that is configured by a RRC signaling or indicated in a MAC CE; or the first number is equal to a predefined number.

5 . The method of claim 3 , wherein the indication of the reporting beam set in the report comprises:
a list of beam state indicators each indicating a beam state in the candidate beam set.

6 . The method of claim 5 , wherein a number of the beam indicator in the list of beam indicator is equal to the second number.

7 . The method of claim 1 , wherein the indication of the candidate beam set comprises the first number of the beam states for a CC or a CC group in a third number of Component Carriers (CCs), wherein the third number is a positive integer.

8 . The method of claim 7 , further comprising:
determining, by the wireless communication device, the second number of the power-related information for a CC, each power-related information for the CC corresponding to a beam state in a reporting beam set for the CC determined based on the candidate beam set of the CC or of the CC group comprising the CC; and sending, by the wireless communication device to the network, a report comprising the power-related information for the CC.

9 . The method of claim 8 , wherein the report comprises an indication of reporting beam set for the CC.

10 . The method of one of claim 8 , wherein the number of field of MPE for a CC is determined according to the number of beam states in the reporting beam set for the CC.

11 . The method of claim 1 , wherein the beam state comprises reference signal (RS) information.

12 . The method of claim 2 , wherein the MPE comprises a power management-maximum power reduction (P-MPR).

13 . A wireless communication method, comprising:
sending, by a network to a wireless communication device, an indication of a candidate beam set comprising a first number of beam states; and receiving, by the network from the wireless communication device, a report comprising a second number of power-related information, wherein each of the power-related information corresponds to a beam state in a reporting beam set determined based on the candidate beam set, and wherein at least one of the first number and the second number is a positive integer.

14 . A wireless communication device, comprising:
at least one processor configured to:
receive, via a transceiver from a network, an indication of a candidate beam set comprising a first number of beam states;
determine a second number of power-related information, each of which corresponds to a beam state in a reporting beam set determined based on the candidate beam set; and
send, via the transceiver to the network, a report comprising the power-related information, wherein at least one of the first number or the second number is a positive integer.

15 . A network node, comprising:
at least one processor configured to:
send, via a transceiver to a wireless communication device, an indication of a candidate beam set comprising a first number of beam states; and
receive, via the transceiver from the wireless communication device, a report comprising a second number of power-related information, wherein each of the power-related information corresponds to a beam state in a reporting beam set determined based on the candidate beam set, and wherein at least one of the first number and the second number is a positive integer.
