Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information indicating a physical downlink control channel (PDCCH) monitoring capability, wherein the PDCCH monitoring capability indicates a minimum length for a group of slots and a maximum number of consecutive slots including at least one search space within the group of slots. The UE may receive a search space set configuration associated with a plurality of search spaces, wherein the search space set configuration is based at least in part on a slot group length that is greater than or equal to the minimum length. The UE may monitor for control information based at least in part on the search space set configuration. Numerous other aspects are described.

Abstract: To provide more efficient FDRA or MCS for some frequency ranges, methods, apparatuses, and computer-readable medium are provided. An example method may include receiving, from a base station and via RRC signaling, one or more FDRA or MCS configurations that are based on a frequency range. The example method may further include communicating with the base station over the frequency range, using an FDRA or MCS based on at least one of the one or more FDRA or MCS configurations.

Abstract: Certain aspects of the present disclosure provide techniques for a physical uplink control channel (PUCCH) resource set for a multiple resource block (RB) PUCCH transmission. A method that may be performed by a user equipment (UE) includes receiving information indicating a PUCCH resource set and a number of RBs parameter and receiving downlink control information (DCI) containing a PUCCH resource indicator (PRI). The method generally includes determining a PUCCH resource from the PICCH resource set and transmitting the PUCCH transmission using the PUCCH resource.

Abstract: Certain aspects of the present disclosure provide techniques for frequency tracking and timing tracking using wideband reference signals (RSs). A method that may be performed by a user equipment (UE) includes monitoring for a wideband RS from a network entity when one or more conditions are met, the wideband RS occupying a wider band of frequency resources than a tracking reference signal (TRS) transmitted by the network entity; and performing at least one of frequency tracking or timing tracking based on the monitoring.

Abstract: Aspects of a multi-stage multi-PDSCH grant are provided which allow a UE to obtain data in a downlink data burst with more scheduling flexibility than single-stage multi-PDSCH grants. A base station provides the UE in a downlink control channel a first portion of downlink control information which indicates a plurality of downlink data transmissions. The UE monitors the downlink control channel for the first portion of downlink control information. Afterwards, the base station sends to the UE a second portion of the downlink control information including parameters for one of the downlink data transmissions. The base station may also send the UE a third portion of the downlink control information including additional parameters for the downlink data transmission. After the UE obtains the portions, the UE decodes the one of the downlink data transmissions indicated at least in part by the first and second portion of the downlink control information.

Abstract: A configuration for a single transport block spanning over multiple slots and having a noncontiguous time domain allocation. The apparatus configures DCI that schedules a plurality of PDSCH symbols or a plurality of PUSCH symbols with a single transport block that spans more than one slot and at least one gap between two adjacent PDSCH symbols or PUSCH symbols. Each of the plurality of PDSCH symbols or PUSCH symbols are contiguous and have a respective SLIV. The apparatus transmits the DCI to at least one UE.

Abstract: Apparatus and method to allow for the activation of SPS/G with multi-PDSCH/PUSCH. The apparatus receives DCI comprising a TDRA assignment that is configured with multiple PUSCHs or multiple PDSCHs. The apparatus selects a first SLIV of a TDRA row indicated by the TDRA assignment comprising one or more SLIVs to activate SPS or a CG. The apparatus transmits the multiple PUSCHs or receiving the multiple PDSCHs based on a selected SLIV of the TDRA row. The apparatus may select the first SLIV for transmission of the multiple PUSCHs or reception of the multiple PDSCHs if a row indicated by the DCI comprises a plurality of SLIVs.
