Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing cross-carrier scheduling. In one aspect, a processor of a wireless device may determine whether downlink control information (DCI) received from a secondary cell schedules communications on a primary cell, and may determine cross-carrier scheduling of communications on the primary cell in response to determining that the DCI received from the secondary cell schedules communications on the primary cell. In another aspect, processor of a network device may schedule communications on the primary cell in the DCI of the secondary cell, and may perform cross-carrier scheduling of communications on the primary cell based on the DCI of the secondary cell.

Abstract: Apparatuses and methods for wireless communication are provided. In an aspect, a user equipment (UE) receives a DCI from a base station, the DCI including an update to a periodically-occurring scheduling, where an absolute time for the update to take effect is specified in an RRC configuration of the DCI. The UE applies the update to the periodically-occurring scheduling for communications of the UE beginning at and following the absolute time. In another aspect, the UE receives at least one downlink communication that updates a plurality of SPS or CG parameters. The UE determines an action time for the update to take effect for each parameter, where the action time is a function of a type of each parameter. The UE applies the update to each parameter for communications of the UE beginning at and following a respective action time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to satisfy an uplink transmission power criterion, such as a specific absorption rate (SAR). The UE may be scheduled to transmit a first uplink message via a first frequency band and a second uplink message via a second frequency band. The UE perform power scaling on the first frequency band and the second frequency band to satisfy the uplink transmission power criterion. For example, the UE may select a first transmission power level for transmitting the first uplink message and a second transmission power level for transmitting the second uplink message based on a function of UE transmission power level over a preceding time interval. The UE may perform uplink power aggregation techniques to temporarily boost transmit power while satisfying the uplink transmission power criterion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to the base station, a beam recovery request including an indication of a multicast beam, where the beam recovery request is transmitted based at least in part on a unicast uplink grant, and where the unicast uplink grant comprises a set of uplink resources for a multicast beam recovery procedure based at least in part on a failure of the multicast beam associated with multicast communications between the UE and the base station. The UE may receive, from the base station in response to the beam recovery request, a response message including an indication of a second uplink grant, an indication of a second beam for communications between the UE and the base station, or both. The UE may transmit a first uplink transmission via the second uplink grant, the second beam, or both.

Abstract: Wireless communication devices, systems, and methods related to downlink control information (DCI) designs for multi-component carrier scheduling are provided. For example, a method of wireless communication can include receiving a downlink control information (DCI) message having a DCI format, the DCI message scheduling a downlink data communication over a single component carrier or multiple component carriers; determining, based on the received DCI message, whether the downlink data communication is scheduled over the single component carrier or the multiple component carriers; and receiving, based on the determining, the downlink data communication over the single component carrier or the multiple component carriers.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a multicast message or a broadcast message that uses a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM). The UE may decode the multicast message or the broadcast message to identify information associated with an RLC unacknowledged mode (RLC-UM) based at least in part on a capability of the UE. The UE may operate in accordance with the RLC-UM based at least in part on decoding the multicast message or the broadcast message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station in a wireless communications system. The UE may perform a random access procedure to communicate with the base station. The base station may configure the UE with different sets of preamble parameters for different types of UEs. The UE may generate a random access preamble based on the sets of preamble parameters according to the type of the UE. The base station may indicate a location of the base station to the UE. The UE may identify a location of the UE. The UE may determine a pre-compensation timing based on a distance from the two locations. The UE and the base station may transmit subsequent communication according to the random access preamble, the pre-compensation timing, or any combination thereof.
