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 (BS), information identifying a core resource set (CORESET) for one or more shared radio frequency spectrum channels. The CORESET may be configured into a plurality of resource blocks based at least in part on a resource block granularity associated with the one or more shared radio frequency spectrum channels. The UE may communicate with the BS using the CORESET. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, transmissions from a neighboring base station may interfere with downlink transmissions from a serving base station to a target user equipment (UE). To coordinate interference between the base stations (e.g., mitigate interference, stabilize interference, etc.), the serving base station may generate an interference coordination message and may transmit the message over-the-air (OTA) to one or more neighboring base stations. The message may include parameters indicating a coordination scheme for the neighboring base station(s) to use for modifying one or more scheduling decisions. The coordination scheme may be configured or dynamically selected and may include interfering beam fixation, interfering beam suppression, or interfering beam avoidance. A neighboring base station receiving the OTA interference coordination message may modify a scheduling decision to mitigate or stabilize interference when the serving base station is transmitting to the target UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a degradation of a communication beam associated with a user equipment (UE). The base station may transmit a first signal identifying a beam switch occasion for the UE. The UE may receive a second signal identifying the beam switch occasion based on an outcome of the contention-based procedure. In some cases, the UE may transmit a third signal acknowledging the beam switch occasion during an acknowledgment opportunity based on the second signal, and may perform a beam switch during the beam switch occasion based on transmitting the third signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a subband configuration for a plurality of subbands configured for the UE, the subband configuration including one or more guard bands for the plurality of subbands. The UE may identify one or more resource blocks, in which to transmit a physical uplink shared channel (PUSCH) communication, based at least in part on the subband configuration. The UE may transmit, to a base station (BS), the PUSCH communication in the one or more resource blocks. Numerous other aspects are provided.

Abstract: A method, a computer-readable medium, and an apparatus are provided that improves the reliability of communication between a base station and a user equipment (UE) using an unlicensed spectrum. A base station transmits an initial signal (IS) to the UE indicating communication to the UE within a Channel Occupancy Time (COT), and transmits a gap transmission during the COT over a time period following the IS and prior to transmitting the communication to the UE.

Abstract: A base station may access a channel following a successful channel access procedure. The base station may transmit an indication of a resource allocation to a user equipment (UE). The resource allocation may include an allocation of resources for subsequent communications between the base station and the UE, for example, defining a set of transmission time intervals (TTIs) during which the UE may transmit repetitions of uplink control information. The UE may also perform a channel access procedure to access the channel. The UE may transmit repetitions of the uplink control information using the set of TTIs according to the resource configuration. In some cases, the UE may stop transmitting uplink control information repetitions after a maximum number repetitions also according to the resource configuration. The base station may then receive and combine the uplink control information.

Abstract: Methods, systems, and devices for wireless communication are described, which may be employed for wireless communication in contention-based (e.g., unlicensed or shared) spectrum. An aperiodic channel state information (CSI) reference signals (RS) may be used for channel quality indicator (CQI) measurements, for example. A user equipment (UE) may receive signaling to indicate the presence of CSI RS and may receive the CSI RS according to the signaling. The UE may then compute a CQI based on CSI RS, and transmit the CQI in a report to a base station. In some examples, a quasi-periodic CSI RS is used. For instance, the UE may determine a different location for the CSI RS. For example, the UE may identify a periodic anchor subframe, and locate the CSI RS based on constant offset from the anchor subframe. Periodic or a clear-channel-assessment-exempt transmission based CSI RS examples are also described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may connect with a base station over a set of component carriers according to a carrier aggregation configuration. The UE may then monitor a search space configured for scheduling multiple component carriers and may receive downlink control information (DCI) based on monitoring the search space. The DCI may include a carrier indicator field (CIF) and may schedule a set of data transmissions over two or more component carriers (e.g., from the set of component carriers). The UE may determine that the two or more component carriers include the first component carrier and the second component carrier based on the monitored search space, the CIF within the DCI, or both. The UE may then transmit and receive the set of data transmissions over the first and second component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a set of component carriers according to a carrier aggregation configuration. In some cases, the UE may receive an indication of one or more groups of units, where each group may include one or more component carriers and/or one or more time intervals of each component carrier. The UE may receive downlink control information (DCI) including one or more fields that are common to a group of units that may schedule a set of data transmissions over the one or more groups of units such that the single DCI may schedule multiple component carriers (e.g., two or more) over one or more time intervals. The UE may transmit or receive the set of data transmissions (e.g., uplink or downlink data transmissions) over the scheduled units based on receiving the DCI.
