Abstract
Methods for flexible signal and channel transmission for increasing channel access opportunities and mitigating interference for supporting NR from 52.6 GHz and above are disclosed. Indication of RMSI CORESET/PDCCH and PDSCH SCS are proposed. A scheme to improve performance, decrease latency and reduce power consumption is also disclosed. And more efficient rate matching is proposed for the frequency range from 52.6 GHz and above.
Claims10
A device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the device to:
- receive a synchronization signal block (SSB), the SSB comprising at least one of a synchronization signal (SS) or a physical broadcast channel (PBCH);
- determine a first timing offset based on an SSB index associated with the SSB;
- determine a half-frame indicator (HFI) associated with the PBCH;
- determine assistance information associated with at least one of the SS or the PBCH, wherein the assistance information indicates a second timing offset;
- and
- determine, based at least in part on the first timing offset, the HFI, and the second timing offset, a total timing offset associated with a cell,
- wherein the second timing offset is applied to adjust a timing position determined based on the SSB index and the half-frame indicator.

A method comprising:
- generating, within a cell, a synchronization signal block (SSB) comprising at least one of a synchronization signal (SS) or a physical broadcast channel (PBCH), the SSB comprising:
- a first timing offset associated with an SSB index associated with the SSB;
- a half-frame indicator (HFI) associated with the PBCH;
- and
- assistance information associated with at least one of the SS or the PBCH, wherein the assistance information indicates a second timing offset;
- sending the SSB;
- and
- receiving a request from a user equipment (UE) to synchronize, wherein the request to synchronize is based at least in part on a total timing offset based at least in part on the first timing offset, the HFI, and the second timing offset,
- wherein the second timing offset is applied to adjust a timing position determined based on the SSB index and the half-frame indicator.
