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.

A method for wireless communication performed by a base station (BS), comprising:
- identifying a synchronization signal (SS) block index associated with a SS block;
- scrambling a physical broadcast channel (PBCH), associated with the SS block, based at least in part on the SS block index;
- and
- transmitting 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.
A wireless communication device, comprising:
- a memory;
- and
- one or more processors operatively 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;
- 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.
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 includes information that identifies 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, and
- wherein the PBCH is scrambled based at least in part the SS block index;
- determining the SS block index based at least in part on the TSS and the PBCH;
- and
- communicating with a base station based on the SS block index.
