Abstract
Embodiments of the present disclosure relate to methods and an apparatuses for synchronization signal (SS) transmission. In example embodiments, a method implemented in a network device is provided. According to the method, information on a plurality of SS blocks to be transmitted by the network device is determined based on at least one of a frequency range and a value of subcarrier spacing. The information at least in part indicates timing for transmitting the plurality of SS blocks The plurality of SS blocks are transmitted to at least one terminal device based on the determined information.
Claims2
A method implemented in a network device, comprising:
- determining, based on at least one of a frequency range and a value of subcarrier spacing, information on a plurality of synchronization signal (SS) blocks to be transmitted by the network device, the information at least in part indicating timing information for transmitting the plurality of SS blocks;
- and
- transmitting, based on the information, the plurality of SS blocks to at least one terminal device served by the network device,
- wherein the determining the information on the plurality of SS blocks comprises determining first information on Physical Broadcast Channel (PBCH), the first information including at least one of the following:
- a payload size for PBCH, second information on one or more fields in PBCH, periodicity of the plurality of SS blocks, the number of scrambling sequences for PBCH, the number of demodulation reference signal (DMRS) sequences for PBCH, mapping information on the scrambling sequences for PBCH, mapping information on the DMRS sequences for PBCH.
A method implemented in a terminal device, comprising:
- determining, based on at least one of a frequency range and a value of subcarrier spacing, information on a plurality of synchronization signal (SS) blocks transmitted by a network device serving the terminal device, the information at least in part indicating timing information for transmitting the plurality of SS blocks by the network device;
- and
- detecting, based on the information, at least one of the plurality of SS blocks,
- wherein the determining the information on the plurality of SS blocks comprises determining first information on Physical Broadcast Channel (PBCH), the first information including at least one of the following:
- a payload size for PBCH, second information on one or more fields in PBCH, periodicity of the plurality of SS blocks, the number of scrambling sequences for PBCH, the number of demodulation reference signal (DMRS) sequences for PBCH, mapping information on the scrambling sequences for PBCH, mapping information on the DMRS sequences for PBCH.
