Abstract
Methods, systems, and devices for wireless communications are described in which measurements of a number of beams that are transmitted from a first device, measured at a second device are provided in a beam switch metric report from the second device. The beam switch metric report may provide the first device with information that is otherwise unavailable to the first device and that may be used for setting beam management parameters.
Claims22
A method for wireless communication at a second device comprising:
- identifying a plurality of beams associated with a first device, each of the plurality of beams of the first device having a different transmission configuration indicator state and a different direction relative to the first device;
- determining, based at least in part on the plurality of beams of the first device, one or more beam switch metrics associated with a beam switch periodicity for switching the second device between two or more of the plurality of beams of the first device;
- transmitting a report to the first device or a third device that indicates the one or more beam switch metrics;
- and
- receiving a control information transmission from the third device that indicates the second device is to transmit an initial access request to the first device, and that indicates one or more synchronization signal block (SSB) transmissions of the first device are to be monitored for reference signal transmissions to determine a preferred transmission beam for subsequent communications with the first device.

A method for wireless communication at a first device, comprising:
- establishing a connection with a second device;
- receiving, from the second device, a report that indicates one or more beam switch metrics associated with a plurality of transmission beams received at the second device, wherein each of the plurality of transmission beams has a different transmission configuration indicator state;
- determining, based at least in part on the report, one or more beam management parameters for one or more transmissions to the second device via one or more of the plurality of transmission beams;
- transmitting the one or more beam management parameters to the second device,
- wherein the first device is a primary base station in a non-stand-alone (NSA) deployment, and the plurality of transmission beams are transmitted by a secondary base station in the NSA deployment, and wherein the method further comprises:
- identifying, by the first device based at least in part on the one or more beam switch metrics, a first transmission beam of the plurality of transmission beams for the second device to transmit an initial access request to the secondary base station.
3 more elements
An apparatus for wireless communication at a second device comprising, comprising:
- a processor,
- memory in electronic communication with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- identify a plurality of beams associated with a first device, each of the plurality of beams of the first device having a different transmission configuration indicator state and a different direction relative to the first device;
- determine, based at least in part on the plurality of beams of the first device, one or more beam switch metrics associated with a beam switch periodicity for switching a second device between two or more of the plurality of beams of the first device;
- transmit a report to the first device or a third device that indicates the one or more beam switch metrics;
- and
- receive a control information transmission from the third device that indicates the second device is to transmit an initial access request to the first device, and that indicates one or more synchronization signal block (SSB) transmissions of the first device that are to be monitored for reference signal transmissions to determine a preferred transmission beam for subsequent communications with the first device.
