Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, techniques for an enhanced paging procedure. A method that may be performed by a user equipment (UE) includes detecting, during a paging occasion (PO), at least one downlink control information (DCI) that indicates a paging message and additional downlink signals and using the additional downlink signals to enhance processing of the paging message.

Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates an association between a sounding reference signal (SRS) resource set and a downlink reference signal resource to be used to determine a transmission property of one or more SRSs in the SRS resource set, wherein the downlink reference signal resource is associated with a first set of ports to be used for performing measurement of the downlink reference signal resource. The UE may determine the transmission property of the one or more SRSs in the SRS resource set using fewer ports than a number of ports included in the first set of ports, based at least in part on a determination that the UE is operating in a power saving mode. The UE may transmit the one or more SRSs using the transmission property. Other aspects are provided.

Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

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: A user equipment (UE) may receive a first group downlink control information transmission associated with a UE group, where the first group downlink control information transmission may reference a second group downlink control information transmission (e.g., according to a pre-notification indication). The UE may determine a feedback condition for the second group downlink control information transmission and monitor for the second group downlink control information transmission. Alternatively, the UE may receive a second group downlink control information transmission referencing the first group downlink control information transmission (e.g., according to a post-confirmation indication), and the UE may determine a feedback condition for the first group downlink control information transmission. Based on the feedback condition, the UE may transmit feedback information, for example, indicating that the UE did not correctly receive the indicated group downlink control information transmission.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for grant processing in uplink centric subframes. An example method generally includes transmitting a first subframe comprising a first grant that includes information for one or more transmissions on that allocated resources in the first subframe to a user equipment (UE) and transmitting the first subframe, with a second grant that allocates resources in at least a second subframe to occur after the first subframe. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control message including a first parameter and a second parameter. The first parameter may identify a first uplink control channel resource set for a first type of UE. The second parameter may identify a second uplink control channel resource set for a second type of UE. In some cases, a UE may receive the control message before receiving configuration information identifying a uplink control channel resource configuration. In some cases, a UE may optionally select an uplink control channel resource set based at least in part on the control message and a type of the UE. Also, a UE may transmit on an uplink using a communication configuration associated with the selected uplink control channel resource set. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing scheduling of wireless communications. A method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating a plurality of minimum scheduling offset values; receiving, from the base station, a signal indicating one of the minimum scheduling offset values as an updated value to be used for communications with the base station and a type of scheduling; determining a delay based on the type of scheduling; and after the reception of the signal, using the updated value for communications with the base station based on the determined delay.

Abstract: Methods, systems, and devices for wireless communication are described related to a duty cycle configuration for power saving. A user equipment (UE) may receive control signaling indicating a duty cycle for cycling between a first power state associated with a first configuration and a second power state associated with a second configuration. In some examples, the first and second configurations may indicate a bandwidth part (BWP) configuration, restricted reception or transmission of one or more channels within the BWP configuration, or both for the UE. The UE may communicate first data traffic in accordance with the first configuration while operating in the first power state. The UE may transition from the first power state to the second power state in accordance with the duty cycle. The UE may communicate second data traffic in accordance with the second configuration while operating in the second power state.
