Abstract
Provided is a method and apparatus for using an offset between a synchronization signal block and a resource block grid. The method may include receiving, by a user device, a synchronization signal (SS) block comprising a synchronization signal and a physical broadcast channel (PBCH), determining, from the PBCH, a value of a subcarrier offset between the SS block and an RB grid, determining, based on the value of the subcarrier offset and a frequency location of the SS block, the RB grid, and decoding, based on the determined RB grid, one or more of a reference signal, a control channel, or a data channel.

A wireless user device comprising:
- an antenna;
- a transceiver;
- a processor;
- and
- memory storing instructions that, when executed by the processor, cause the wireless user device to:
- receive, among a plurality of synchronization signal (SS) blocks, a first SS block, wherein the first SS block comprises a first synchronization signal and a first physical broadcast channel (PBCH), and wherein the first PBCH indicates a value associated with a first subcarrier offset between the first SS block and a first resource block (RB) grid;
- determine, based on the value associated with the first subcarrier offset and a frequency location of the first SS block, a frequency location of the first RB grid;
- and
- decode, based on the determined frequency location of the first RB grid, one or more of:
- a reference signal, a control channel, or a data channel,
- wherein the plurality of SS blocks comprise the first SS block and a second SS block,
- wherein the second SS block comprises a second synchronization signal and a second PBCH,
- wherein the second PBCH indicates a value associated with a second subcarrier offset between the second SS block and a second RB grid, and
- wherein a distance between the first SS block and a center frequency of a carrier is different from a distance between the second SS block and the center frequency of the carrier.
