Abstract
Aspects of the disclosure provide a method and apparatus for transmitting a synchronization broadcast transmission. At least one candidate transmission location corresponding to at least one synchronization signal/physical broadcast channel block (SSB) to be transmitted, is determined, where a number of the at least one candidate transmission location is greater than a number of SSBs in one time interval. Further, synchronization broadcast transmission including the at least one SSB is generated, and the generated synchronization broadcast transmission is transmitted at the at least one candidate transmission location in a beam sweeping manner.
Claims12
A method for receiving a synchronization broadcast transmission, applied in an unlicensed frequency band, comprising:
- performing, by a user equipment (UE), a search at a plurality of candidate transmission locations to receive at least one synchronization broadcast transmission from a base station at part of the plurality of candidate transmission locations, wherein each of the at least one synchronization broadcast transmission comprises a respective one of at least one synchronization signal/physical broadcast channel block (SSB), and a number of the plurality of candidate transmission locations is greater than a pre-configured maximum number of SSBs transmittable by the base station in one time interval;
- and
- acquiring, by the UE, at least one SSB identifier of the at least one SSB from the at least one synchronization broadcast transmission, wherein the at least one SSB identifier is carried in the at least one SSB,
- wherein a maximum value of the at least one SSB identifier corresponds to the pre-configured maximum number of SSBs transmittable by the base station in one time interval, or the maximum value of the at least one SSB identifier corresponds to the number of the plurality of candidate transmission locations.
A device for receiving a synchronization broadcast transmission, comprising:
- a processor;
- and
- a memory configured to store instructions executable by the processor,
- wherein the processor is configured to:
- perform a search at a plurality of candidate transmission locations to receive at least one synchronization broadcast transmission from a base station at part of the plurality of candidate transmission locations, wherein each of the at least one synchronization broadcast transmission comprises a respective one of at least one synchronization signal/physical broadcast channel block (SSB), and a number of the plurality of candidate transmission locations is greater than a pre-configured maximum number of SSBs transmittable by the base station in one time interval;
- and
- acquire at least one SSB identifier of the at least one SSB from the at least one synchronization broadcast transmission, wherein the at least one SSB identifier is carried in the at least one SSB,
- wherein a maximum value of the at least one SSB identifier corresponds to the pre-configured maximum number of SSBs transmittable by the base station in one time interval, or the maximum value of the at least one SSB identifier corresponds to the number of the plurality of candidate transmission locations.
A non-transitory computer-readable storage medium, in which computer instructions are stored, wherein the instructions are executed by a processor to implement following actions:
- performing a search at a plurality of candidate transmission locations to receive at least one synchronization broadcast transmission from a base station at part of the plurality of candidate transmission locations, wherein each of the at least one synchronization broadcast transmission comprises a respective one of at least one synchronization signal/physical broadcast channel block (SSB), and a number of the plurality of candidate transmission locations is greater than a pre-configured maximum number of SSBs transmittable by the base station in one time interval;
- and
- acquiring at least one SSB identifier of the at least one SSB from the at least one synchronization broadcast transmission, wherein the at least one SSB identifier is carried in the at least one SSB;
- wherein a maximum value of the at least one SSB identifier corresponds to the pre-configured maximum number of SSBs transmittable by the base station in one time interval, or the maximum value of the at least one SSB identifier corresponds to the number of the plurality of candidate transmission locations.
