Abstract: Aspects described herein relate to configuring control resource sets (CORESETs) and search spaces in fifth generation new radio (5G NR). In an example, the aspects may include determining, by a network entity, one or more configurations of one or more physical downlink control channel (PDCCH) candidates, wherein the one or more configurations include: modifying of at least one of one or more parameters for one or more search spaces, one or more parameters for one or more CORESETs, the one or more search spaces, and the one or more CORESETs; or skipping monitoring of at least one of the one or more parameters for the one or more search spaces, the one or more parameters for the one or more CORESETs, the one or more search spaces, and the one or more CORESETs; and transmitting, by the network entity to one or more user equipments (UEs), the one or more configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify at least one of a control resource set zero (CORESET0) field or a search space zero (SS0) field in a master information block (MIB). The UE may identify, based at least in part on whether the UE is a reduced capability UE, at least one of: a CORESET0 configuration associated with a first value indicated in the CORESET0 field, or an SS0 configuration associated with a second value indicated in the SS0 field. Numerous other aspects are provided.

Abstract: Extension of power efficient paging in a wireless network. In some examples, information is buffered for a time period corresponding to a paging slot, or both the paging slot and at least one adjacent slot. The buffered control information is processed to detect paging downlink control information (DCI) and a tracking reference signal (TRS). Based on the processing, the paging message is scheduled in a physical downlink shared channel (PDSCH) in the paging slot. In some examples, quasi-co-located (QCL) processing may be performed on the TRS and the paging DCI paging message, and a paging message is scheduled, based on the QCL processing, in a physical downlink shared channel (PDSCH) in a same or offset paging slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a bandwidth part (BWP) frequency hopping configuration for a BWP and a first configuration of a sounding reference signal (SRS) resource. The UE may receive a second configuration of the SRS resource for one or more frequency hops of the BWP frequency hopping configuration, wherein the second configuration resolves a partial overlap of the SRS resource with an SRS resource of a second UE in the one or more frequency hops. The UE may transmit one or more SRSs based at least in part on the second configuration of the SRS resource. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating to switch from a first slot format to a second slot format. The first slot format may include symbols for reference signal transmissions and symbols for data transmissions. Thus, the first slot format may be a full-TDM slot that supports time division multiplexing (TDM) reference signals and data. The second slot format may be a hybrid TDM/frequency division multiplexing (FDM) slot or a full-FDM slot that includes at least one symbol for frequency division multiplexing (FDM) reference signals and data. Based on a capability of the UE and the control message, the UE may switch to the second slot format and communicate a reference signal in a symbol configured for FDM. That is, the reference signal may be FDMed with data according to the second slot format.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a random access channel (RACH) resource associated with a capability level of the UE. The capability level-specific RACH resource may overlap one or more other RACH resources. The UE may identify whether the UE is enabled to report capability information or preferences, or both, using the capability level-specific RACH resource based on how the capability level-specific RACH resource overlaps with the one or more other RACH resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a relationship between a first signal and a second signal. The UE may communicate with a wireless communication device based at least in part on using a first transmission configuration for the first signal, the first transmission configuration specifying that the first signal includes a guard interval that spans a duration and is based at least in part on a delay spread of the first signal. The UE may communicate with the wireless communication device based at least in part on using a second transmission configuration for the second signal, the second transmission configuration specifying that the second signal includes the guard interval based at least in part on the indication of the relationship. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating a configuration for uplink control information (UCI) that supports an indication of hybrid automatic repeat request (HARQ) feedback, an indication of a scheduling request, an indication of channel state information (CSI), and an indication of additional information. In some aspects, the indication of the additional information may be associated with uplink resources configured for the UE. For example, the indication of the additional information may be an indication that the UE is to skip one or more uplink resources configured for the UE. The UE may transmit the UCI in accordance with the configuration, where the UCI includes at least one of the indication of the HARQ feedback, the indication of the scheduling request, the indication of the CSI, or the indication of the additional information.

Abstract: Certain aspects of the present disclosure provide techniques for differentiating physical random access channel (PRACH) repetition numbers. An example method, performed by a network entity, includes receiving at least one physical random access channel (PRACH) repetition, of a group of PRACH repetitions, determining a number of PRACH repetitions in the group, based on at least one resource associated with the at least one PRACH repetition, and processing the group of PRACH repetitions, in accordance with the determination.

Abstract: Aspects presented herein may enable a UE to transmit a PUCCH formed by a flexible concatenation of different types of blocks, such as one or more data sample blocks, one or more RS blocks, and/or one or more gap blocks within a PUCCH symbol. In one aspect, a UE receives, from a network entity, an indication to transmit one or more PUCCH symbols that are associated with a coherent PUCCH format, where each PUCCH symbol of the one or more PUCCH symbols associated with the coherent PUCCH format includes at least one RS sample block, at least one data sample block, or at least one gap sample block multiplexed in time-domain. The UE transmits, for the network entity, the one or more PUCCH symbols.
