Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A user equipment (UE) may receive, via a control channel in a primary cell, one or more downlink control information (DCI) messages that include a secondary cell (SCell) dormancy indication and a request for hybrid automatic repeat request (HARQ) feedback. The DCI messages may have a format associated with downlink scheduling, and fields used to carry the SCell dormancy indication and the request for HARQ feedback may have a configuration that depends on whether the DCI messages are used to schedule a downlink data transmission. Furthermore, in some aspects, a DCI message may include a field that has a value to indicate whether the DCI message does or does not schedule a downlink data transmission, to enable the UE to correctly receive and decode the SCell dormancy indication and the request for HARQ feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an AMF may receive, from a user equipment (UE), a communication associated with a request for an identifier. The AMF may transmit, to the UE, the identifier, wherein the identifier is based at least in part on a synchronization signal block (SSB) periodicity and a number of paging frames per discontinuous reception (DRX) cycle. Numerous other aspects are described.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, at least one SSB. The apparatus may also determine a RSRP of the at least one SSB. Additionally, the apparatus may transmit, to the base station if the RSRP of all of the at least one SSB is less than a threshold, an indication of a reduced UE capability of the UE during a RACH procedure. The apparatus may also transmit, to the base station if the RSRP of one of the at least one SSB is greater than or equal to the threshold, the indication of the reduced UE capability of the UE after entering into a RRC connected state upon completion of the RACH procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may switch from a first group of search space sets for monitoring a physical downlink control channel (PDCCH) to an empty group of search space sets. The UE may refrain from monitoring the PDCCH based at least in part on switching to the empty group. In some aspects, the UE may switch from a first group of PDCCH search space sets to at least one dormant group of PDCCH search space sets identified in configuration information. The UE may also process one or more PDCCH search space sets of the at least one dormant group of PDCCH search space sets based at least in part on the received configuration information.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method for wireless communications at a user equipment (UE) includes determining one or more performance metrics related to communications over a wireless channel and comparing the one or more performance metrics with a performance level for the communications over the wireless channel. The method may include selecting a power mode for the UE based at least in part on the comparing and determining an operating state of a subset of a plurality of radio frequency front end elements of at least one active radio frequency chain of the UE based at least in part on the power mode and a priority of the one or more performance metrics. The method may also include adjusting the subset of the plurality of radio frequency front end elements based at least in part on the operating state.
