Abstract

Methods, systems, and devices for wireless communications are described. In some example, a base station may facilitate panel activation or deactivation at a user equipment (UE). For example, a UE including a set of panels may establish a connection with a base station. The base station may transmit an activation configuration message activating or deactivating a subset of panels at the UE. Based on the activation configuration message, the UE may select one or more panels from the set of panels and transmit an uplink transmission to the base station using the selected one or more panels.

Claims (66)

1 . A method for wireless communication at a user equipment (UE), comprising:

establishing a connection between a network device and the UE, the UE having a plurality of panels for wireless communications;

receiving, from the network device, via a first bandwidth part, a first activation configuration message comprising a codepoint corresponding to two or more panels of the plurality of panels;

selecting a first subset of the plurality of panels for an uplink transmission based at least in part on the codepoint mapped to the two or more panels of the plurality of panels;

transmitting, to the network device, the uplink transmission via the first bandwidth part using the first subset of the plurality of panels;

switching from communicating with the network device via the first bandwidth part to communicating with the network device via a second bandwidth part;

suspending the first activation configuration message while switching to communicating with the network device via the second bandwidth part;

receiving a second activation configuration message to activate or deactivate one or more second panels of the plurality of panels, wherein the second activation configuration message is received over the second bandwidth part;

selecting a second subset of the plurality of panels for a second uplink transmission using the second bandwidth part based at least in part on the second activation configuration message;

switching from communicating with the network device via the second bandwidth part to communicating with the network device via the first bandwidth part; and

reselecting the first subset of the plurality of panels in accordance with switching back to communicating with the network device via the first bandwidth part and the first activation configuration message.

2 . The method of claim 1 , wherein receiving the first activation configuration message comprises:

receiving a control message comprising a single bit field for the two or more panels, wherein the bit field comprises one of a bit for activating the two or more panels or a bit for deactivating the two or more panels.

3 . The method of claim 1 , further comprising:

receiving, before receiving the first activation configuration message, a radio resource control message indicating a mapping between each codepoint of a set of codepoints and one or more panels of the plurality of panels, wherein the first activation configuration message is received via downlink control information, and the codepoint is from the set of codepoints.

4 . The method of claim 1 , further comprising:

deactivating the two or more panels based at least in part on the second activation configuration message.

5 . The method of claim 1 , further comprising:

receiving a control message indicating a set of component carriers of a group of serving cells configured for the UE, wherein the first activation configuration message comprises a message to activate or deactivate the two or more panels when communicating using a component carrier of the set of component carriers; and

communicating with the network device using the component carrier of the set of component carriers and the first subset of the plurality of panels of the plurality of panels based at least in part on the first activation configuration message.

6 . The method of claim 1 , wherein the first activation configuration message comprises a radio resource control (RRC) message, a medium access control control element (MAC-CE), or a downlink control information (DCI) message.

7 . A method for wireless communication at a network device comprising:

establishing a connection between the network device and a user equipment (UE), the UE having a plurality of panels for wireless communications;

transmitting, to the UE, via a first bandwidth part, a first activation configuration message comprising a codepoint mapped to two or more panels of the plurality of panels;

receiving, from the UE, an uplink transmission via the first bandwidth part in accordance with the codepoint mapped to the two or more panels of the plurality of panels;

switching from communicating with the UE via the first bandwidth part to communicating with the UE via a second bandwidth part;

suspending the first activation configuration message while switching to communicating with the UE via the second bandwidth part;

transmitting, via a second bandwidth part, a second activation configuration message to activate or deactivate one or more second panels of the plurality of panels;

communicating, with the UE, via the second bandwidth part in accordance with the second activation configuration message;

switching from communicating with the UE via the second bandwidth part to communicating with the UE using the first bandwidth part; and

communicating with the UE in accordance with the switching back to the first bandwidth part and the first activation configuration message.

8 . The method of claim 7 , wherein transmitting the first activation configuration message comprises:

transmitting a control message comprising a single bit field for the two or more panels, wherein the single bit field comprising one of a bit for activating the two or more panels or a bit for deactivating the two or more panels.

9 . The method of claim 7 , further comprising:

transmitting, before transmitting the first activation configuration message, a radio resource control message indicating a mapping between each codepoint of a set of codepoints and one or more panels of the plurality of panels, wherein the first activation configuration message is received via downlink control information, and the codepoint is from the set of codepoints.

10 . The method of claim 7 ,

wherein the second activation configuration message indicates to activate two or more second panels different from the two or more panels.

11 . The method of claim 7 , further comprising:

transmitting a control message indicating a set of component carriers of a group of serving cells configured for the UE, wherein the first activation configuration message comprises a message to activate or deactivate the two or more panels when communicating with the network device using a component carrier of the set of component carriers; and

communicating with the UE using the component carrier of the set of component carriers in accordance with the first activation configuration message.

12 . The method of claim 7 , wherein the first activation configuration message comprises a radio resource control (RRC) message, a medium access control control element (MAC-CE), or a downlink control information (DCI) message.

13 . An apparatus for wireless communication at a user equipment (UE), comprising:

one or more processors; and

one or more memories coupled with the one or more processors storing instructions executable by the one or more processors to cause the apparatus to:

establish a connection between a network device and the UE, the UE having a plurality of panels for wireless communications;

receive, from the network device, via a first bandwidth part, a first activation configuration message to activate or deactivate one or more panels of the plurality of panels;

select a first subset of the plurality of panels for an uplink transmission based at least in part on the first activation configuration message; and
