Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.

Abstract: A configuration to reduce a timeline for non-codebook based uplink precoding procedures. The apparatus measures an NZP-CSI-RS over one or more beams from a base station. The apparatus determines a single beam for communication with the base station based on measurement of the NZP-CSI-RS. The apparatus transmits a PUSCH using the single beam and based on determining the single beam for communication with the base station. The apparatus may receive a configuration from the base station to perform a SRS-less non-codebook based uplink precoding procedure. The UE may transmit the PUSCH using the single beam and without transmitting an SRS further based on the configuration from the base station. The apparatus may skip transmission of an SRS between measurement of the NZP-CSI-RS and transmission of the PUSCH.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication via a non-terrestrial network (NTN). In one aspect, a method for wireless communication includes initiating, by a user equipment (UE), a registration process with a network entity of an NTN to access the NTN. The method also includes transmitting, by the UE to the network entity, UE capability information of the UE. The method further includes receiving, by the UE from the network entity, a handover command, the handover command comprising a handover time indicator associated with a target handover time for the UE to perform a handover operation from a first beam to a second beam. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a UE-requested BFD/BFR reference signal. In aspects, the UE may transmit, to a base station, a request for a list of a set of beams for BFD and a list of a set of candidate beams for BFR. The UE may receive, from the base station based on the transmitted request, information indicating the set of beams for BFD and the set of candidate beams for BFR.

Abstract: Techniques and apparatus for using downlink control information (DCI) to avoid hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One example technique involves a user equipment (UE) receiving an indication of a plurality of SPS configurations, each SPS configuration allocating the UE with a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. Information for resolving a conflict between a first HARQ process ID associated with a first SPS occasion of a first of the plurality of SPS configurations and a second HARQ process ID associated with a second SPS occasion of a second of the plurality of SPS configurations is received. The first SPS occasion occurs prior to the second SPS occasion. The conflict is resolved based on the information.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive an indication of a subcarrier spacing (SCS) for communications in a plurality of transmission time intervals (TTIs), where a TTI include a set of symbols, a corresponding set of cyclic prefixes, and a padding duration. The device may receive a control signal indicating a configuration for the padding duration, at least a portion of which may be reallocated as one or more additional symbols with corresponding one or more additional cyclic prefixes. In some examples, the one or more additional cyclic prefixes and at least a first portion of the set of cyclic prefixes may be reduced in duration in comparison with a remaining portion of the set of cyclic prefixes. The device may communicate during the padding duration using the one or more additional symbols and the corresponding one or more additional cyclic prefixes.

Abstract: Methods, systems, and devices for scrambling initialization indication for higher bands are described. For example, a user equipment (UE) may receive a synchronization signal block (SSB) from a base station, the SSB including a primary synchronization signal (PSS), a data payload, and a demodulation reference signal (DMRS). The UE may identify a first part of a cell identifier (ID) of the base station, a second part of the cell ID, or both, indicated in a sequence of the DMRS, indicated in the data payload, or a combination thereof. The UE may monitor for a message from the base station based on identifying the cell ID.
