Dynamic receiver chain allocation

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

• a processor;
• and
• a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to:
• receive, from a network node, a message configuring a group of component carriers (CCs);
• allocate, to each CC of the group of CCs based on receiving the message configuring the group of CCs, one of a respective first number of receiver chains, from a group of receiver chains available at the UE, or a respective second number of receiver chains, from the group of receiver chains, to maximize a total number of receiver chains actively used for decoding the group of CCs, collectively;
• and
• decode each CC of the group of CCs based on the respective first number of receiver chains or the respective second number of receiver chains allocated to the CC.

A method for wireless communication by a user equipment (UE), comprising:

• detecting an event associated with a wireless communication channel;
• allocating, to each component carrier (CC) of a group of CCs based on detecting the event, one of a respective first number of receiver chains, from a group of receiver chains available at the UE, or a respective second number of receiver chains, from the group of receiver chains, to maximize a total throughput for decoding the group of CCs collectively;
• and
• decoding each CC of the group of CCs based on the respective first amount of receiver chains or the respective second amount of receiver chains allocated to the CC.

A method for wireless communication by a user equipment (UE), comprising:

• detecting an event associated with a wireless communication channel;
• allocating, in response to detecting the event, a respective first number of receiver chains from a group of receiver chains available at the UE to each component carrier (CC) of a first subset of CCs, of a group of CCs, currently associated with a respective second number of receiver chains from the group of receiver chains, and a respective second number of receiver chains from the group of receiver chains to each CC of a second subset of CCs, of the group of CCs, currently associated with a respective first number of receiver chains from the group of receiver chains, based on and a throughput gain associated with switching each CC of the first subset of CCs to the respective first number of receiver chains being greater than a throughput loss associated with switching each CC of the second subset of CCs to the respective second number of receiver chains;
• and
• decoding each CC of the group of CCs based on the respective first number of receiver chains or the respective second number of receiver chains allocated to the CC.
