METHOD AND APPARATUS FOR NR SIDELINK SS/PBCH BLOCK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240236888 titled 'METHOD AND APPARATUS FOR NR SIDELINK SS/PBCH BLOCK

The abstract of this patent application describes a method for a first user equipment (UE) to generate sidelink synchronization signals and physical broadcast channels based on a sidelink synchronization identity (sl-sid) and a set of resources. These signals include symbols for a sidelink primary synchronization signal (s-pss) and a sidelink secondary synchronization signal (s-sss), each generated using specific sequences and modulation techniques. The generated signals are then transmitted over sidelink channels established with a second UE.

  • The method involves determining a sidelink synchronization identity (sl-sid) and a set of resources.
  • Generating sidelink synchronization signals and physical broadcast channels based on the sl-sid and resources.
  • The generated signals include symbols for a sidelink primary synchronization signal (s-pss) and a sidelink secondary synchronization signal (s-sss).
  • The s-pss sequence is based on a binary phase shift keying (bpsk) modulated m-sequence with a sequence length of 127 and low cross-correlation with a pss.
  • The s-sss sequence is based on a bpsk modulated gold-sequence with a sequence length of 127.
  • Transmitting the generated signals over established sidelink channels with a second UE.

Potential Applications: - This technology can be applied in wireless communication systems to enhance sidelink synchronization and channel establishment between UEs.

Original Abstract Submitted

a method of a first ue comprises: determining a sidelink synchronization identity (sl-sid) and a set of resources; generating at least one sidelink synchronization signal and physical broadcast channel (s-ssb) based on the sl-sid and the set of resources, wherein each s-ssb of the at least one s-ssb includes first two symbols for a sidelink primary synchronization signal (s-pss) and second two symbols for a sidelink secondary synchronization signal (s-sss); generating a first sequence corresponding to the s-pss, wherein the first sequence is determined based on a binary phase shift keying (bpsk) modulated m-sequence with a 127 of sequence length and a low cross-correlation with a pss; generating a second sequence corresponding to the s-sss, wherein the second sequence is determined based on a bpsk modulated gold-sequence with a 127 of sequence length; and transmitting, the at least one s-ssb over sidelink channels established with the second ue.
