Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message scheduling a first message and including an indication that the first message is scheduled for full-duplex operation with a second message. The indication may be a DCI field configured for indicating full-duplexing, or the DCI field may be an existing DCI field configured to also indicate full-duplexing. The UE may identify a set of parameters associated with the full-duplex operation of the first message based on receiving the DCI message that includes the indication, and the UE may communicate the first message using the set of parameters associated with the full-duplex operation and based on the indication included in the DCI message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine a grant for performing uplink transmissions based on a radio resource control (RRC) message. The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station (BS) may detect remote interference, with one or more uplink communications on a physical uplink shared channel (PUSCH) associated with the first BS, caused by propagation of one or more reference signal (RS) communications, transmitted by a second BS, out of a coverage area of the second BS and into a coverage area of the first BS due to reflection of the one or more RS communications. The coverage area of the first BS and the coverage area of the second BS are non-overlapping coverage areas. The first BS may adjust, based at least in part on detecting the remote interference, one or more radio resource allocations of the PUSCH associated with the first BS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station during a physical downlink control channel (PDCCH) monitoring occasion (PMO), first downlink control information (DCI) scheduling the UE for a first physical downlink shared channel (PDSCH) resource on a first component carrier and for a second PDSCH resource on a second component carrier. The UE may receive, during the PMO, second DCI scheduling the UE for a third PDSCH resource on the second component carrier. The UE may identify a set of downlink assignment indices (DAIs) for the first DCI and the second DCI, where the first DCI has one or more DAIs whose values are based on the first DCI scheduling PDSCH resources on different component carriers. The UE may transmit feedback based on the set of DAIs.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

Abstract: Certain aspects of the present disclosure provide techniques for allocating a number of physical downlink control channel (PDCCH) blind decoding candidates to a user equipment (UE) in dual connectivity mode. An example method generally includes allocating a resource budget among a first cell group and a second cell group, wherein the resource budget includes a number of physical downlink control channel (PDCCH) blind decoding candidates and a number of control channel elements (CCEs) supported by the UE, and monitoring for PDCCH candidates in the first cell group and second cell group in accordance with the allocated resource budget.

Abstract: Bandwidth part (BWP) inactivity and mode switching supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. A wireless device may be provided with multiple BWP configurations, such as may include a default half duplex BWP configuration and a default BWP configuration. Multiple timers, such as may include a BWP inactivity timer and a duplex mode timer, may be implemented for timer-based switching between BWP configurations, such as any combination of a default half duplex BWP configuration, an active half duplex BWP configuration, a default full duplex BWP configuration, and an active full duplex BWP configuration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit downlink control information (DCI) to a user equipment (UE) indicating a joint field for at least a first component carrier (CC) and a second CC of a carrier aggregation configuration. For example, the joint field may include a rate matching (RM) indication for the first CC and the second CC, a zero power channel state information reference signal (ZP-CSI-RS) indication for the first CC and the second CC, or both. In some cases, the RM indication may include a common RM resource (RMR) configuration applicable for both the first CC and the second CC or per-CC RMR configurations that indicate separate RMRs for each of the CCs. Additionally, the ZP-CSI-RS indication may include a set identifier that indicates a resource set for ZP-CSI-RS resources for both the first CC and the second CC.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a connection, with base station, over a first and second component carrier and may monitor a search space configured for scheduling multiple component carriers. In some cases, the UE may be configured to monitor a search space allocated for a virtual component carrier associated with scheduling multiple component carriers, or the UE may be configured to monitor for a subset of physical downlink control channel (PDCCH) candidates in search spaces associated with the first and second component carriers, where the subset of PDCCH candidates may be allocated for multi-component carrier scheduling. The UE may receive downlink control information (DCI) that schedules a set of data transmissions over the first and second component carriers and the UE may perform or receive the set of data transmissions over the first and second component carrier.
