Abstract
Aspects of the present disclosure describe synchronizing frequency and/or timing in a wireless communication system. A synchronization channel frequency can be determined as one of a plurality of possible synchronization channel frequencies within a frequency band. A tone of one or more synchronization signals that corresponds to the synchronization channel frequency can be punctured, and the one or more synchronization signals can be transmitted as centered around the synchronization channel frequency.
Claims26
A method for synchronizing frequency and/or timing in a wireless communication system, comprising:
- detecting one or more synchronization signals received from a base station in a broadcast channel over the synchronization channel frequency within a system bandwidth for a radio technology from a network, wherein the synchronization channel frequency is one of a plurality of possible synchronization channel frequencies for the radio technology in a synchronization channel raster for the system bandwidth, wherein the synchronization channel raster is larger than a channel raster used to define a center carrier frequency of the system bandwidth, and wherein the one or more synchronization signals are centered around the synchronization channel frequency;
- receiving, from the base station after detecting the one or more synchronization signals and in a control plane, radio resource control (RRC) signaling including a system information block (SIB), wherein the SIB indicates an offset associated with the center carrier frequency of the system bandwidth from the synchronization channel frequency over which the one or more synchronization signals are detected within the system bandwidth;
- and
- communicating with the network based on the one or more synchronization signals, and using the system bandwidth based on the center carrier frequency associated with the offset.
