UE instructed dynamic antenna sharing

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

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
• configure a first distribution of a set of radio capabilities over a plurality of operational scenarios, wherein the set of radio capabilities includes a set of antenna resources of the first UE, and wherein the first distribution of the set of radio capabilities includes a distribution of the set of antenna resources over the plurality of operational scenarios;
• transmit, to a network entity, a signal comprising at least one portion of the first distribution to indicate to the network entity to configure a scheduling configuration based on the at least one portion of the first distribution;
• receive, from the network entity, a network response to the signal, wherein the network response comprises one or more of:
• an acknowledgement (ACK) to the signal, a negative ACK (NACK) to the signal, or a network suitability for distributing the set of radio capabilities;
• adjust, based on the network response, the first distribution to obtain a fourth distribution of the set of radio capabilities;
• and
• communicate with the network entity based on the fourth distribution of the set of radio capabilities.

An apparatus of wireless communication at a network entity, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
• receive, from a first user equipment (UE), a signal indicating a UE-selected distribution of a set of radio capabilities over a plurality of operational scenarios, wherein the set of radio capabilities includes a set of antenna resources of the first UE, and wherein the UE-selected distribution of the set of radio capabilities includes a distribution of the set of antenna resources over the plurality of operational scenarios;
• configure a scheduling configuration based on the signal;
• and
• communicate, based on the scheduling configuration, with the first UE, wherein the scheduling configuration is applied while the first UE is in a radio resource control (RRC)-connected state, wherein to configure the scheduling configuration, the at least one processor is configured to:
• configure the scheduling configuration to not conform with the UE-selected distribution of the set of radio capabilities, and wherein the scheduling configuration comprises a second distribution of the set of radio capabilities, and wherein to communicate with the first UE, the at least one processor is configured to:
• communicate, based on the second distribution of the set of radio capabilities, with the first UE.

A method of wireless communication at a first user equipment (UE), comprising:

• configuring a first distribution of a set of radio capabilities over a plurality of operational scenarios, wherein the set of radio capabilities includes a set of antenna resources of the first UE, and wherein the first distribution of the set of radio capabilities includes a distribution of the set of antenna resources over the plurality of operational scenarios;
• transmitting, to a network entity, a signal comprising at least one portion of the first distribution to indicate to the network entity to configure a scheduling configuration based on the at least one portion of the first distribution;
• and
• communicating, based on the first distribution of the set of radio capabilities and the scheduling configuration, with the network entity, wherein the scheduling configuration is applied while the UE is in a radio resource control (RRC)-connected state, wherein the scheduling configuration is not compatible with the first distribution of the set of radio capabilities, and wherein communicating with the network entity comprises:
• receiving, from the network entity, a second distribution of the set of radio capabilities compatible with the scheduling configuration;
• determining, based on the second distribution, a third distribution of the set of radio capabilities;
• and
• communicating, based on the third distribution of the set of radio capabilities and the scheduling configuration, with the network entity.
