Abstract
Aspects described herein relate to communicating with a base station over multiple frequency bands using a first beam, and switching from the first beam to the second beam during a time period or based on a timing of the reference band. Other aspects relate to transmitting an indication of one or more parameters for determining a reference band of the multiple frequency bands to use as a timing reference for switching beams for communicating over the multiple frequency bands.
Claims30
An apparatus for wireless communication, comprising:
- a transceiver;
- a memory configured to store instructions;
- and
- one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to execute the instructions to cause the apparatus to:
- concurrently communicate with a base station over multiple frequency bands using a same first beam;
- and
- switch, according to beam switching criteria, from the first beam to a second beam during a time period, wherein the time period is:
- one of a limited number of time periods during which the apparatus is allowed to switch the first beam to the second beam within a specified duration;
- or
- based on a timing reference associated with a reference band of the multiple frequency bands.
An apparatus for wireless communication, comprising:
- a transceiver;
- a memory configured to store instructions;
- and
- one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to execute the instructions to cause the apparatus to:
- communicate with a user equipment (UE) over multiple frequency bands using a first beam;
- and
- transmit, to the UE, an indication of one or more parameters for determining a reference band of the multiple frequency bands to use as a timing reference for switching beams for communicating over the multiple frequency bands.
A method for wireless communication by a user equipment (UE), comprising:
- concurrently communicating with a base station over multiple frequency bands using a same first beam;
- and
- switching, according to beam switching criteria, from the first beam to a second beam during a time period, wherein the time period is:
- one of a limited number of time periods during which the UE is allowed to switch the first beam to the second beam within a specified duration;
- or
- based on a timing reference associated with a reference band of the multiple frequency bands.
