摘要： A wireless device transmits, to a base station, at least one first measurement report of at least one synchronization signal of a cell. An indication, of one or more channel state information reference signals (CSI-RSs) of the cell, is received from the base station based on: the at least one first measurement report. and a first antenna port of the one or more CSI-RSs being quasi-collocated with a second port of the at least one synchronization signal. Based on the indication, at least one second measurement report of the one or more CSI-RSs is transmitted. Based on the at least one second measurement report, a downlink control information is received that initiates a random access procedure of the cell based on at least one first CSI-RS from the one or more CSI-RSs.

摘要： Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

摘要： The present disclosure provides a method for configuring and receiving a common control channel, and a device for configuring and receiving a common control channel. The method for configuring a common control channel includes configuring a common control channel and a primary synchronization signal and/or a secondary synchronization signal in a subband where a user equipment resides in a frequency division multiplexing manner; and transmitting the common control channel by using configured resources. Embodiments of the present disclosure may improve resource utilization by configuring the common control channel.

摘要： This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with a Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.

摘要： Aspects of the present disclosure provide mechanisms for transmitting discovery signals to enable discovery of a cell. Synchronization signal blocks (SSBs) carrying the cell identifier of the cell may then be transmitted either on-demand or with a higher periodicity than discovery signals. The discovery signals and SSBs may be transmitted within a same bandwidth part and on at least overlapping sets of frequency resources.

摘要： This disclosure provides systems, methods, and devices for wireless communication that support allocation of resources for a physical broadcast channel (PBCH) for reduced bandwidth devices. In a first aspect, a method includes monitoring, by a user equipment (UE) configured for reduced bandwidth operation, at least a subset of a first set of time and frequency resources allocated to a synchronization signal block (SSB) for UEs configured for non-reduced bandwidth operation. The SSB includes synchronization signals and a PBCH. The method includes monitoring, by the UE, a second set of time and frequency resources allocated to the PBCH for UEs configured for reduced bandwidth operation. The method includes receiving, by the UE, the synchronization signals and the PBCH within at least the subset of the first set of time and frequency resources and the second set of time and frequency resources. Other aspects and features are also claimed and described.
