Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: Methods, systems, and devices for wireless communication are described. After receiving a transmission, a user equipment (UE) may store status information for the transmission and send an acknowledgment message that includes a signature. When a base station receives an acknowledgment message with a signature, it may transmit a subsequent downlink grant that includes the same signature. The signature included in a downlink grant may enable the UE to retrieve a stored status and decode the next data transmission based on the retrieved status. That is, the base station may use the signature in the grant to indicate which acknowledgment the grant is based on.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for enabling a wireless system implementing multicast transmissions to control feedback reports from multiple user equipments (UEs) and to address feedback codebook misalignment issues. In particular, aspects provide for multicast transmission grants including multiple feedback timing indicators (K1) in which the multicast transmission grants are configured to configure different UEs for multicast transmission feedback reporting in which feedback codebooks transmitted in various uplink control transmission occasions from the different UEs have a same size. Other aspects and features are also claimed and described.

Abstract: Wireless communications systems and methods related to improving multiplexing capability in a frequency spectrum are provided. A first wireless communication device obtains a configuration for communicating a communication signal in a frequency spectrum. The configuration is based on at least a number of wireless communication devices scheduled to communicate in a time period. The configuration indicates resources in the frequency spectrum over the time period and a frequency distribution mode of the resources. The first wireless communication device communicates, with a second wireless communication device, the communication signal in the frequency spectrum during the time period based on the configuration.

Abstract: In an aspect of the disclosure an apparatus, e.g., a base station, maybe configured to receive, from a UE, ACK/NACK feedback indicating that a subset of CBGs of a set of transmitted CBGs failed to be properly decoded. The apparatus maybe further configured to retransmit the subset of CBGs based on the ACK/NACK feedback and transmit information indicating the CBGs being retransmitted. In one configuration, a TB of new data maybe transmitted with the retransmitted subset of CBGs in a subframe/slot. In an aspect, a UE may be configured to determine that one or more CBGs of a received set of CBGs failed to be properly decoded at the UE, and send ACK/NACK feedback indicating the one or more CBGs that failed to be decoded. The UE maybe further configured to receive a retransmission of CBGs in the set of CBGs, and information indicating the retransmitted CBGs.

Abstract: Methods, systems, and devices for wireless communications are described. In some implementations, a method for wireless communication at a user equipment (UE) is described that includes identifying that the UE is in carrier aggregation communication with a primary and secondary cell. The method may also include monitoring, during one or more time intervals, UE-specific search spaces of the secondary cell for control information scheduling data communications on the primary cell. The method may include switching, during one or more different time intervals, to monitoring UE-specific search spaces of the primary cell. Another method describes wireless communication at a base station that may configure a UE to communicate via carrier aggregation, transmit control information via the secondary cell to the UE during downlink TTIs, and transmit control information via the primary cell to the UE during uplink TTIs.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a user equipment (UE) with a control resource set (CORESET) with multiple transmission configuration indicator (TCI) states. The UE may determine TCI state configurations for one or more search space sets associated with the CORESET, where different search space sets associated with the CORESET may have different TCI state configurations. For example, each search space set may be associated with a first TCI state of the CORESET, a second TCI state of the CORESET, or both. The UE may monitor for downlink control information (DCI) messages in physical downlink control channel (PDCCH) candidates of the search space sets according to respective TCI state configurations for the search space sets. Such a configuration may flexibly support a base station transmitting DCI using different TCI state configurations in PDCCH candidates of a single CORESET.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for downlink control information (DCI) among a plurality of physical downlink control channel (PDCCH) candidates that are associated with each other, the plurality of PDCCH candidates including at least a first PDCCH candidate in a first transmission time period and a last PDCCH candidate in a second transmission time period. The UE may identify a reference timing rule based at least in part on the association between the plurality of PDCCH candidates, the reference timing rule indicating that a reference time is to be determined based at least in part on either the first transmission time period or the second transmission time period. The UE may determine the reference time based at least in part on the reference timing rule and communicate based at least in part on the reference time.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a first user equipment (UE) to manage the reuse of resources reserved for sidelink communications by the UE. The first UE may identify scheduling information for a sidelink shared channel between the first UE and a second UE, and the first UE may reserve a set of resources for subsequent sidelink communications by the first UE. The first UE may transmit a sidelink control message indicating the scheduling information and the reserved resources to one or more neighboring UEs. The sidelink control message may include a reuse allowance indicator that may indicate whether the set of reserved resources is available for spatial reuse by the neighboring UEs. The neighboring UEs may determine whether the reuse the reserved resources based on the control message, the reuse allowance indicator, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration message which includes one or more parameters pertaining to blind decoding attempts by the UE of repetition-based physical downlink control channel (PDCCH) candidates. The UE may determine, from the configuration message, a blind decoding count mode which indicates a process for counting a number of blind decoding attempts of repetition-based PDCCH candidates. The UE may monitor for one or more repetitions of a downlink control information by attempting to blind decode the one or more repetitions of a PDCCH candidate in accordance with a maximum blind decode count and the blind decoding count mode.
