Abstract
Aspects of the present disclosure relate to techniques for transmitting and processing synchronization signals (SS) for different purposes. In some cases, transmitting multiple SS blocks simultaneously using frequency division multiplexing (FDM), and possibly different beams, may allow a UE to reduce a measurement window.
Claims19
A method for performing wireless communications by a network entity, comprising:
- identifying one or more time intervals for transmitting synchronization signal (SS) blocks for one or more user equipments (UEs) to use for at least one of initial access or measurement purposes;
- transmitting, within one of the time intervals, SS blocks at different frequency locations using frequency division multiplexing (FDM);
- transmitting, to the one or more UEs, information for processing the SS blocks, wherein the information indicates a mapping between SS block indices and beams;
- and
- signaling information to the one or more UEs to enable multiple frequency measurement according to measurement correspondence information, wherein the measurement correspondence information indicates a measurement of a first SS block sent using a first beam index on a first frequency is to be replaced by a measurement of a second SS block sent using a second beam index on a second frequency.

A method for performing wireless communications by a user equipment, comprising:
- receiving, within one of time intervals, synchronization signal (SS) blocks transmitted at different frequency locations using frequency division multiplexing (FDM);
- receiving signaling of information for processing the SS blocks, wherein the information indicates a mapping between SS block indices and beams;
- and
- performing at least one of initial access or measurement based on the SS blocks, wherein the UE is configured to reduce a measurement window by processing SS blocks sent using different sets of ports in different time intervals.
