Abstract
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a synchronization signal (SS) block index associated with a SS block; scramble a physical broadcast channel (PBCH), associated with the SS block, based at least in part on the SS block index; and transmit the SS block including a tertiary synchronization signal (TSS) and the PBCH, wherein the TSS includes information that identifies the SS block index associated with the SS block, and wherein the TSS is frequency division multiplexed with the PBCH in two or more orthogonal frequency-division multiplexed (OFDM) symbols of the SS block. Numerous other aspects are provided.
Claims24
A method for wireless communication performed by a base station (BS), comprising:
- identifying a synchronization signal (SS) block index associated with a SS block;
- and
- transmitting the SS block including a tertiary synchronization signal (TSS) and a physical broadcast channel (PBCH),
- wherein the TSS comprises a sequence indicative of at least a portion of the SS block index associated with the SS block,
- wherein the TSS is frequency division multiplexed with the PBCH in two or more orthogonal frequency-division multiplexed (OFDM) symbols of the SS block, and
- wherein the PBCH is modulated based at least in part on the TSS.
A wireless communication device, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors configured to:
- identify a synchronization signal (SS) block index associated with a SS block;
- and
- transmit the SS block including a tertiary synchronization signal (TSS) and a physical broadcast channel (PBCH),
- wherein the TSS comprises a sequence indicative of at least a portion of the SS block index associated with the SS block,
- wherein the TSS is frequency division multiplexed with the PBCH in two or more orthogonal frequency-division multiplexed (OFDM) symbols of the SS block, and wherein the PBCH is modulated based at least in part on the TSS, and
- wherein the PBCH is modulated based at least in part on the TSS.
A method for wireless communication performed by a user equipment (UE), comprising:
- receiving a synchronization signal (SS) block including a tertiary synchronization signal (TSS) and a physical broadcast channel (PBCH),
- wherein the TSS comprises a sequence indicative of at least a portion of an SS block index associated with the SS block, and
- wherein the TSS is frequency division multiplexed with the PBCH in two or more orthogonal frequency-division multiplexed (OFDM) symbols of the SS block,
- demodulating the PBCH based at least in part on the TSS;
- determining the SS block index based at least in part on the sequence of the TSS;
- and
- communicating with a base station using the SS block index.
