Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating synchronization signals for cell synchronization. Certain aspects of the present disclosure provide a method for wireless communication. The method generally includes determining a symbol index for transmitting a sequence; determining an amount of cyclical shift in one of a frequency domain and a time domain to apply to the sequence, wherein the amount of cyclical shift in the frequency domain is based on the sequence and the symbol index; shifting the sequence by the amount of cyclical shift; and transmitting the shifted sequence in a symbol corresponding to the symbol index.

Abstract: A mechanism that allows the successful decoding of MCS information of cell edge UEs while retaining the performance for the other UEs of the cell is provided. In one aspect, a UE may determine an uplink control coding rate based on an uplink signal quality. The UE may encode uplink control data based on the uplink control coding rate. The UE may apply a pattern of unused resource element locations in uplink control resource elements based on the uplink control coding rate. The UE may transmit the uplink control resource elements with the pattern of unused resource element locations. In another aspect, an eNB may receive uplink control resource elements. The eNB may determine an uplink control coding rate based on a pattern of resource element locations in the uplink control resource elements. The eNB may decode uplink control data based on the uplink control coding rate.

Abstract: Aspects described herein relate to configuring a device to skip multiple paging early indication (PEI) occasions. An indication of a skip duration of multiple discontinuous receive (DRX) cycles to skip in monitoring for a paging early indication (PEI) can be received, and a reduced power state can be entered for the skip duration. After the skip duration, an increased power state can be entered to monitor for the PEI, a synchronization signal block (SSB), or one or more reference signals.

Abstract: Aspects are provided allowing a UE to transmit repetitions of an ULT, PEI-R, or other uplink reference signal for on-demand SSB, RMSI, or paging transmissions. A base station initially transmits an indication of a configured uplink repetition mode, which may comprise a first, second, or third mode in which a one-to-one, one-to-many, or many-to-many mapping exists between downlink reference signals and uplink occasions, respectively. Afterwards, the UE receives downlink reference signals via different transmission beams of the base station. In response to the downlink reference signals, the UE transmits an uplink reference signal repetition in one or more uplink occasions associated with one or more of the downlink reference signals according to the configured uplink repetition mode. In response to the uplink reference signal repetition, the base station may transmit a SSB, RMSI, or paging message. Thus, a balance between network energy savings and uplink signal reliability may be achieved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) burst set that includes a plurality of SSBs, a majority of the SSBs in the SSB burst set having an SSB symbol and a corresponding physical broadcast channel (PBCH) symbol that is located a fixed number of symbols from the SSB symbol. The UE may obtain a location of the PBCH symbol based at least in part on the fixed number of symbols. Numerous other aspects are described.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a repeater node. The apparatus may receive, at one or more first antennas of the node, a first signal via at least one first beam. The apparatus may measure, at one or more third antennas of the node, at least one of a power or a quality of at least one third beam. The at least one of the power or the quality of the at least one third beam may be measured at a same time as the first signal is received. The apparatus may forward, at one or more second antennas of the node, the first signal via at least one second beam.
