Abstract
Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance functionality of directional repeaters (for instance, wireless devices that relay directional wireless signals). By adding even limited capability within the directional repeaters to buffer digital samples, the functionality of the directional repeaters may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources.
Claims30
An apparatus for wireless communications by a first wireless device, comprising:
- a memory;
- and
- a processor coupled with the memory, the memory and the processor configured to:
- relay synchronization signal blocks (SSBs) of an SSB burst from a network entity to at least one second wireless device using a first set of one or more beams for receiving the SSBs from the network entity and a second sets of one or more beams for transmitting the SSBs received via the first set of beams, wherein at least one beam of the second set of one or more beams is used to relay the SSBs received from the network entity using different beams than the first set of one or more beams;
- match a correspondence between beams of the first and the second set of one or more beams used for relaying the SSBs, wherein matching the correspondence comprises:
- using a same beam of the second set of one or more beams that was used to transmit the SSBs to the at least one second wireless device for receiving one or more messages from the at least one second wireless device;
- and
- using a same beam of the first set of one or more beams that was used to receive the SSBs from the network entity for transmitting one or more messages to the network entity.
