Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a base station, a medium access control-control element (MAC-CE) including an offset change command. The method also includes adjusting an offset within a periodic pattern based on the offset change command. A method of wireless communication, by a base station, includes detecting a misalignment between an arrival time of data relative to a periodic pattern. The method also includes transmitting, to a user equipment (UE), a medium access control-control element (MAC-CE) including an offset change command to adjust an offset within the periodic pattern.

Abstract: Aspects of the present disclose provide various methods and apparatuses for communicating, controlling, and configuring component carrier and bandwidth part (BWP). A scheduling entity receives a capability report from a user equipment (UE). The capability report indicates a capability of the UE to utilize at least one of carrier aggregation (CA) or one or more bandwidth parts. The scheduling entity transmits a command to the UE to reconfigure at least one of a CA configuration or a bandwidth part (BWP) configuration. The scheduling entity determines an anticipated response timing of an acknowledgment (ACK) of the command based on the capability report received from the UE. The scheduling entity receives the ACK according to the anticipated response timing.

Abstract: Methods, systems, and devices for wireless communications are described that provide improved repetition techniques for autonomous uplink transmissions. Configuration information may be provided from a base station to a user equipment (UE) for autonomous uplink transmissions, that may indicate initial resources for an initial uplink transmission slot and retransmission resources for a number of retransmissions. Time resources within the retransmission resources may be configured to provide enhanced reliability, such as by being configured in non-contiguous slots to avoid one or more other transmission channels. Time resources within slots may also be configured to prevent persistent collisions with autonomous uplink transmissions or retransmissions of two or more different UEs.

Abstract: Certain aspects of the present disclosure provide techniques for applying precoding patterns to shared channel transmission repetitions. In one example, a method of transmitting data from a device in a wireless communication network, includes: determining a number of repetitions to transmit data in the wireless communication network; determining a precoding pattern that specifies a precoder to be applied to each repetition of the number of repetitions; and transmitting the data according to the number of repetitions and according to the precoding pattern.

Abstract: A wireless communications system may support a large number of user equipment (UEs) and a base station may transmit resource configuration information to a group of UEs, in which the configuration information identifies the group of UEs. In some cases, the base station may receive a data transmission from a UE of the UE group that the base station cannot decode. The base station may then transmit a group-common feedback signal to the UE group. Once the transmitting UE of the UE group receives the group-common signal, the UE may re-transmit the data to the base station. By sending a group-common feedback signal, the base station may conserve resources, improve reliability and increase successful uplink transmissions from UEs.

Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.
