Abstract: A user equipment (UE) may be configured to communicate a number of transmissions that may each have separate feedback processes. A feedback configuration for providing feedback for such separate feedback processes may be determined based on semi-static signaling and dynamic signaling. In some cases, semi-static signaling, such as radio resource control (RRC) signaling and dynamic signaling, such as downlink control information (DCI), may together provide a feedback configuration for a particular transmission. The semi-static signaling may provide a number of bits of feedback information, an interpretation of the bits of feedback information, or combinations thereof, and dynamic signaling may indicate that one or more of the bits are to have one of a number of available interpretations, may indicate that one or more additional bits are to be included with feedback, of combinations thereof. Feedback techniques as discussed herein may be used to provide feedback for uplink or downlink transmissions.

Abstract: A user equipment (UE) may transmit a random access request message to a base station in a random access procedure to access a wireless network. In response, the base station may transmit a random access response message to the UE including an uplink grant for a first set of uplink resources for the UE to transmit a radio resource control (RRC) message. The UE may determine a second set of uplink resources for transmitting the RRC message, for example, based on additional uplink grants received in the random access response message. Additionally or alternatively, the UE may derive additional grants implicitly from the first uplink grant received from the base station. The UE may transmit the RRC message to the base station using the first and/or second sets of uplink resources and establish a connection based on the RRC message for subsequent uplink and downlink communications.

Abstract: Methods, systems, and devices for wireless communications are described to enable base station and a user equipment (UE) to mitigate interference when using full-duplex communications. For example, a base station communicating with a UE via full-duplex communications may indicate for the UE to align the time of its uplink transmissions with the time the UE receives downlink transmissions. Additionally or alternatively, the base station may indicate a timing alignment window for the UE, where the window may consist of an allowed time period the UE may use to select a time to begin uplink transmissions. In some examples, the base station may select a cyclic prefix for full-duplex communications, where the cyclic prefix may be longer than a cyclic prefix used for other communications. Further, the base station may select uplink frequency and downlink frequency bands separated by a defined guard band for full-duplex communications.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may report a phase-noise compensation reference signal (PCRS) configuration to a base station to enable per-UE PCRS signaling. For example, a UE may operate in a wireless communications system using carrier frequencies greater than 6 GHz, which may be affected by phase noise. The UE may accordingly determine a PCRS configuration based on a capability to receive signals. The PCRS configuration may include a resource mapping for one or more PCRS, a number of PCRS ports used for PCRS, a multiplexing scheme for one or more PCRS ports, or the UE's phase noise estimation capability. The UE may then transmit a reporting message including the PCRS configuration to a base station. The base station may use the PCRS configuration for PCRS transmissions to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a dropping rule relating to: a first triggering communication, of a first transmit receive point (TRP), that triggers a first timeline for a first subsequent communication of the first TRP, and a second triggering communication, of a second TRP, that triggers a second timeline for a second subsequent communication of the second TRP, wherein the dropping rule indicates one or more communications to be dropped when the first triggering communication starts after a start of the second triggering communication and the first subsequent communication starts before a start of the second subsequent communication; and drop the one or more communications based at least in part on the dropping rule. Numerous other aspects are provided.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: Wireless communications systems and methods related to synchronization signal (SS) transmission coordination among base stations (BSs) and restricted SS measurements at user equipments (UEs) are provided. A first BS transmits a first SS burst in a first SS transmission period of a plurality of SS transmission periods. The first SS transmission period is designated to the first BS. A second SS transmission period of the plurality of SS transmission periods is designated to a second BS. The first SS transmission period and the second SS transmission period are different. The first BS receives, from a UE, a first signal in synchronization with the first SS burst. The first signal includes a SS measurement of the first SS burst.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a beam failure recovery period, that a configured control resource set at least partially overlaps with a beam failure recovery control resource set. The UE may configure, based at least in part on the at least partial overlap, a receive beam to receive the beam failure recovery control resource set. The UE may receive a control signal over the beam failure recovery control resource set during the beam failure recovery period.
