Abstract
A user equipment (UE) may transmit a first request for the uplink (UL) communications with a network node to be switched from a first serving cell in a first frequency range and a second serving cell in a second frequency range to a serving cell over a single first frequency range based on switching from a static codebook based hybrid beamforming to at least one of an adaptive beam weight hybrid beamforming. The UE may further transmit a second request for the network node to measure an interference caused by the UL communications from the UE with the adaptive beam weight hybrid beamforming.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive an indication from at least one network node to switch from a static codebook based hybrid beamforming to at least one of an adaptive beam weight hybrid beamforming for uplink (UL) communications;
- transmit a first request for the UL communications with the at least one network node to be switched from a first serving cell in a first frequency range and a second serving cell in a second frequency range to a serving cell over a single first frequency range, based on receiving the indication to switch from the static codebook based hybrid beamforming to at least one of the adaptive beam weight hybrid beamforming;
- receive an affirmative response to switch the UL communications with the at least one network node from the first serving cell in the first frequency range and the second serving cell in the second frequency range to the serving cell over the single first frequency range;
- and
- switch the UL communications with the at least one network node from the first serving cell in the first frequency range and the second serving cell in the second frequency range to the serving cell over the single first frequency range.

A method of wireless communication at a user equipment (UE), comprising:
- receiving an indication from at least one network node to switch from a static codebook based hybrid beamforming to at least one of an adaptive beam weight hybrid beamforming or a non-codebook based hybrid beamforming for uplink (UL) communications;
- transmitting a first request for the UL communications with the at least one network node to be switched from a first serving cell in a first frequency range and a second serving cell in a second frequency range to a serving cell over a single first frequency range, based on receiving the indication to switch from the static codebook based hybrid beamforming to at least one of the adaptive beam weight hybrid beamforming;
- receiving an affirmative response to switch the UL communications with the at least one network node from the first serving cell in the first frequency range and the second serving cell in the second frequency range to the serving cell over the single first frequency range;
- and
- switching the UL communications with the at least one network node from the first serving cell in the first frequency range and the second serving cell in the second frequency range to the serving cell over the single first frequency range.
