Abstract: Scheduling with split symbols for beam management is described. An apparatus is configured to receive, from a network node, DL signaling including a symbol in a first slot, and to measure a first measurement of a first beam during a first time portion, and a second measurement of a second beam during a second different time portion, of the symbol. The apparatus is configured to communicate, with the network node, using the first or second beam based on at least one of the first measurement or the second measurement. Another apparatus is configured to provide, for a UE, DL signaling including a symbol in a first slot, and to communicate, with the UE, using the first or second beam based on a first and/or second measurement. The first and second measurements are of first and second beams during a first and second different time portions of the symbol, respectively.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a high speed train (HST) cell, a system information block (SIB) indicating an HST flag based at least in part on the UE camping on the HST cell. The UE may disconnect from the HST cell and camping on a non-HST cell based at least in part on a UE mobility in an HST railway. The UE may determine that disconnecting from the non-HST cell and camping on a new HST cell is to be prioritized over remaining on the non-HST cell, based at least in part on the UE being in the HST railway and based at least in part on a priority of HST cells being greater than a priority of non-HST cells. Numerous other aspects are described.

Abstract: Aspects of the disclosure are directed to generation of N-port dynamic beams. For example, a user equipment (UE) may be using a 2-port predefined receive beam for communication with a wireless node. The UE may estimate a channel using the predefined receive beam to measure a rank2 reference signal received from the wireless node. The UE may generate a dynamic beam weight to maximize a communication parameter based on the estimated channel. The UE may then apply the dynamic beam weight to an antenna array.

Abstract: A network entity configures a synchronization signal block (SSB) using SSB resources that convey a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) within an SSB resource area of a resource grid bounded in time by a first configured integer number of time units and bounded in frequency by a second configured integer number of physical channels. A product of the first configured integer number and the second configured integer number is a predetermined constant value, each symbol of the SSB has an equal number of resource elements (REs), and all REs in the each symbol of the SSB, except REs within a frequency guard band between any two of the PSS, the SSS, and the PBCH in the each symbol of the SSB, have non-zero values. A user equipment receives the SSB in the SSB resources as a beamformed SSB.

Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a message indicating UE assistance information (UAI). In some examples, the UE may transmit a request for network assistance information (NAI) for candidate cells. The UE may receive a control message indicating the NAI and a set of candidate cells for a conditional serving cell change. The UE may perform the conditional serving cell change based on the NAI for one or more candidate cells. In some examples, the UE may select a target cell from the set of candidate cells, and the UE may receive a control message indicating one or more coverage enhancement schemes supported by the target cell. The UE may perform a random access procedure based on the one or more coverage enhancement schemes supported by the target cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a non-cell-defining (NCD)-synchronization signal and physical broadcast channel (PBCH) block (SSB) (NCD-SSB) configuration indicating one or more parameters corresponding to transmission, via at least one NCD-SSB burst, of at least one NCD-SSB set associated with at least one cell, the at least one cell comprising at least one of a primary cell or a secondary cell. The UE may receive the at least one NCD-SSB burst based at least in part on the NCD-SSB configuration. Numerous other aspects are described.

Abstract: A base station may configure a user equipment (UE) with a discontinuous reception (DRX), e.g., connected mode DRX (CDRX), and the UE may select a synchronization signal block (SSB) set to perform an SSB warm-up to wake up, search, and measure the SSB set to improve the performance of the UE during a DRX ON duration. The UE may select the SSB set based on a time difference of the SSB set relative to the DRX ON duration. The UE may be configured to wake up to measure one of a first SSB set or a second SSB set having a smaller time difference relative to the DRX ON duration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a communication link using a first serving beam on a secondary component carrier (SCC). The UE may identify a link failure associated with the first serving beam. The UE may transmit an out-of-range indication associated with the first serving beam in association with the link failure. The UE may report measurement information for one or more candidate serving beams. The UE may receive an indication of a second serving beam from the one or more candidate serving beams. The UE may switch to the second serving beam for the SCC. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a signal, transmitted by a base station, using a set of candidate beams. The UE may communicate, with the base station based at least in part on the measurement of the signal, using a first beam from the set of candidate beams. The UE may determine to switch the first beam based on a first value for a beam parameter associated with a second beam, from the set of candidate beams, satisfying a condition. The UE may measure, based at least in part on the determination to switch the first beam, the second beam to obtain a second value of the beam parameter. The UE may switch the first beam to the second beam if the second value satisfies a condition. Numerous other aspects are provided.
