Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) carrying information indicating an updated configuration for the UE, wherein the DCI is associated with a hybrid automatic repeat request (HARQ) process for which HARQ feedback regarding the DCI is disabled. The UE may transmit the HARQ feedback regarding the DCI based at least in part on the DCI carrying the information indicating the updated configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource configuration for communications with a base station on a multiple sets of resources across multiple component carriers, the resource configuration including at least a first set of resources on a first component carrier and a second set of resources on a second component carrier. The UE may receive, from the base station, a downlink control information (DCI) message on the first component carrier, the DCI message including a DCI format that controls the multiple of sets of resources across the plurality of component carriers. The UE may determine that the first set of resources and the second set of resources are one of activated or released based on a first indication in the DCI message.

Abstract: Methods, systems, and devices for wireless communications are described. Layer two (L2) relay techniques may support early measurements for relay selection. During a transition to an idle or inactive state, a remote user equipment (UE) may receive a radio resource control (RRC) release message indicating a list of relay UE candidates on which to perform early measurements. The remote UE may perform the early measurements and may transmit a measurement report to abase station indicating the measurements. Based on the early measurements of the relay UE candidates performed by the remote UE and the measurement report, the base station may select a relay UE candidate-remote UE relay pairing, and may transmit an indication of the pairing to the remote UE along with other relay configuration information. Using the identified relay pairing, the remote UE may establish a sidelink connection with the identified relay UE candidate.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may communicate with a network device in an idle or disconnected state using preconfigured uplink resources (PURs). The UE may transmit uplink data, and may begin to monitor for a PUR response message corresponding to the uplink data after a configurable time offset. The Base station may indicate the configurable time offset in an RRC release message, another message, or the UE may select the configurable time offset from a set of configurable time offsets based on one or more system parameter values. Additionally, the UE may not monitor for PUR response messages after every PUR occasion during which it transmits uplink data.

Abstract: Aspects of the disclosure relate to devices and methods for managing carrier aggregation. Downlink control information (DCI), transmitted via a primary cell (PCell), may include one or more secondary cell (SCell) dormancy indication (SDI) value(s) for one or more secondary cells (SCells). That DCI may also schedule a physical downlink shared channel. A scheduled entity may transmit acknowledgment information indicating whether the scheduled entity successfully received the DCI. Where the SDI indicates a switch in behavior relative to one or more SCell(s) and the acknowledgment information indicates that the scheduled entity successfully received that DCI, the one or more SCell(s) transition from dormant to active or vice-versa. Accordingly, the scheduled entity conforms its behavior to provide the appropriate dormancy and non-dormancy behavior when utilizing, in addition to the PCell, one or more SCell(s) for wireless communication in carrier aggregation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE in a sidelink communication with the first UE, an indication to switch from utilizing a first sidelink bandwidth part (SL-BWP) to utilizing a second SL-BWP. The UE may selectively switch from utilizing the first SL-BWP to utilizing the second SL-BWP based at least in part on receiving a positive acknowledgment message from the second UE. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide various devices, methods, and systems for dynamic spectrum sharing of a spectrum between different radio access technologies and multiple frequency division duplexing modes. Dynamic spectrum sharing (DSS) is a technology that allows wireless network operators to share a spectrum between different radio access technologies (RATs). DSS allows an operator to dynamically allocate some existing 4G spectrum to 5G use to deliver 5G services using a shared spectrum.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via multi-component carrier. The UE may monitor control channel occasions (e.g., physical downlink control channel (PDCCH) occasions), to receive wireless communications from a base station (e.g., a next-generation NodeBs (gNB)). For example, the UE may receive multiple downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The UE may identify one or multiple downlink assignment indices (DAI) in the received DCI messages. In some examples, the UE may generate one or more feedback bits of a HARQ feedback codebook (also referred to as an acknowledgement codebook). The one or more feedback bits include a same number of feedback bits for each downlink assignment index associated with each DCI message.
