Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive one or more downlink control information (DCI) transmissions including a plurality of transmit power control (TPC) commands. The plurality of TPC commands may relate to an uplink channel transmit power for a plurality of uplink beam-pairs. The wireless communication device may determine the uplink channel transmit power for the plurality of uplink beam-pairs based at least in part on the plurality of TPC commands. Numerous other aspects are provided.

Claims (63)

1. A method of wireless communications, comprising:

identifying, by a base station, one or more downlink control information (DCI) transmissions including a plurality of transmit power control (TPC) commands,

a second TPC command, of the plurality of TPC commands, corresponding to a second type of channel; and

providing, by the base station and to a wireless communication device, the one or more DCI transmissions.

2. The method of claim 1 , wherein data is transmitted on the plurality of uplink beam-pairs using an uplink channel transmit power.

3. The method of claim 1 , further comprising:

receiving a first uplink beam-pair, of the plurality of uplink beam-pairs, from the wireless communication device after providing the one or more DCI transmissions; and

receiving a second uplink beam-pair, of the plurality of uplink beam-pairs, from the wireless communication device after providing the one or more DCI transmissions.

4. The method of claim 3 ,

wherein the first uplink beam-pair is transmitted with a first transmit power, and

wherein the second uplink beam-pair is transmitted with a second transmit power.

5. The method of claim 1 , wherein each of the plurality of uplink beam-pairs is associated with a corresponding TPC command of the plurality of TPC commands.

6. The method of claim 1 , wherein the one or more DCI transmissions include the plurality of TPC commands in a sequence corresponding to a sequence of link indices.

7. The method of claim 1 , wherein each of the plurality of TPC commands is associated with a corresponding cell identifier and information identifying a corresponding uplink beam-pair.

8. The method of claim 1 , wherein uplink channel transmit powers for two or more of the plurality of uplink beam-pairs are determined based at least in part on a single TPC command of the plurality of TPC commands.

9. The method of claim 1 , wherein the plurality of TPC commands are provided via a multicast transmission.

10. The method of claim 9 ,

wherein the multicast transmission does not include a set of padding bits, and

wherein a quantity of TPC bits of the multicast transmission is associated with a quantity of TPC commands of the plurality of TPC commands.

11. The method of claim 9 ,

wherein the multicast transmission includes a set of padding bits,

wherein the set of padding bits includes information associated with the plurality of TPC commands.

12. A base station for wireless communication, comprising:

a memory; and

one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:

identify one or more downlink control information (DCI) transmissions including a plurality of transmit power control (TPC) commands,

the plurality of TPC commands relating to a plurality of uplink beam-pairs,

a first TPC command, of the plurality of TPC commands, corresponding to a first type of channel, and

a second TPC command, of the plurality of TPC commands, corresponding to a second type of channel; and

provide, to a wireless communication device, the one or more DCI transmissions.

13. The device of claim 12 , wherein data is transmitted on the plurality of uplink beam-pairs using an uplink channel transmit power.

14. The device of claim 12 , wherein each of the plurality of uplink beam-pairs is associated with a corresponding TPC command of the plurality of TPC commands.

15. The device of claim 12 , wherein the one or more DCI transmissions include the plurality of TPC commands in a sequence corresponding to a sequence of link indices.
