Methods, systems, and devices for dynamic rate matching patterns for spectrum sharing are described. In some examples, a user equipment (UE) may measure one or more interference levels associated with resources of a physical resource block (e.g., interference levels associated with respective subcarriers or other division in the frequency domain, with respective symbol durations or other division in the time domain, or a combination thereof), and determine a rate matching pattern based on the interference level measurements. In some examples, the rate matching pattern may include a pattern of resources for communications between the UE and a base station (e.g., for downlink communications). The UE may transmit an indication of the rate matching pattern to the base station, and the base station may schedule or transmit one or more subsequent downlink transmissions based at least in part on the indication of the rate matching pattern received from the UE.

Dynamic rate matching patterns for spectrum sharing

Methods related to wireless communication systems and uplink (UL) rank adaptation are provided. A user equipment (UE) receives, from a base station (BS), a configuration indicating a resource associated with a plurality of UL reference signal ports. The UE determines, based on at least one of an overheating status, a throughput, or a latency, a quantity of transmission layers for a transmission. The UE transmits, to the BS, an indication of at least one of (1) one or more UL reference signal ports of the plurality of UL reference signal resources associated with the UL reference signal resource based on the quantity of transmission layers, or (2) a number of UL reference signal ports associated with the multi-port UL reference signal resource based on the quantity of transmission layers.

Uplink rank adaptation for MIMO communication

Apparatus, methods, and computer-readable media for connected mode discontinuous reception (C-DRX) on/off synchronization coordination between user equipment and network are disclosed herein. A user equipment (UE) may transmit a UE capability message that indicates that the UE has capability to support C-DRX on/off synchronization coordination with the network entity. The UE may receive a DRX synchronization coordination configuration based on the UE capability message, the DRX synchronization coordination configuration configuring the UE with the C-DRX on/off synchronization coordination with the network entity. The UE may determine that an inactivity timer associated with the DRX synchronization coordination configuration is within a threshold time to expire, and transmit special uplink signaling indicating that the UE intends to transition into an off duration in a DRX cycle based on the inactivity timer being within the threshold time to expire.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for interference mitigation techniques between wireless communications and aircraft radio altimeters. In some aspects, a user equipment (UE) and a network entity may support one or more signaling- or configuration-based interference avoidance mechanisms associated with usage of a C-band at one or both of the UE and the network entity. The UE may support a capability according to which the UE is able to monitor a frequency band used by aircraft radio altimeters and the UE may request a modification to a C-band connection (such as request a release of the C-band connection) if the UE detects or measures signaling from an aircraft radio altimeter. Similarly, the network entity may modify the C-band connection if the network entity receives the request from the UE or itself detects or measures signaling from an aircraft radio altimeter.

Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a bandwidth size indication that indicates a respective bandwidth size configured for each operating configuration of a set of operating configurations supported at the UE. The UE may transmit, to the base station, a priority indication for at least one operating configuration of the set of operating configurations based on the bandwidth size indication. The priority indication may correspond to a bandwidth size of the at least one operating criterion satisfying one or more criteria for data traffic. The base station may transmit, to the UE, a configuration indication that indicates to communicate according to a first operating configuration of the set of operating configurations based on the priority indication. The UE may communicate the data traffic with the base station based on the first operating configuration.

Certain aspects of the present disclosure provide techniques and apparatus for inter-frequency signal property prediction using machine learning techniques. An example method generally includes determining one or more properties of a received signal from a wireless device on a first frequency band. An estimate of the one or more properties of signals on a second frequency band is generated, while a transceiver is tuned to the first frequency band, using a machine learning model trained to generate the estimate based on the determined one or more properties of the received signal on the first frequency band. The transceiver is tuned to the second frequency band for subsequent communications with the wireless device based on the estimate of the one or more properties of the signals on the second frequency band.

The UE may transmit the RLC status report using an indicated format, of the one or more formats or an additional format for transmitting the RLC status report, wherein use of the indicated format is based at least in part on a physical layer indication or a medium access control (MAC) layer indication. Numerous other aspects are described.

A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.
