Abstract: Techniques are disclosed for enabling low-power positioning of a first mobile device using differential angle of arrival (AoA). A differential AoA between a first AoA of a first wireless reference signal at a second mobile device and a second AoA of a second wireless reference signal at the second mobile device is obtained, where the first wireless reference signal is transmitted by a wireless network node, and the second wireless reference signal is transmitted by the first mobile device. The position of the first mobile device is determined based at least in part on the differential AoA. The position of the first mobile device is then provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling that indicates at least a first random access channel (RACH) occasion (RO) partition and a second RO partition. The first RO partition may be associated with different uplink transmission capabilities than the second RO partition. The UE may select an RO in the first RO partition or the second RO partition based at least in part on a metric that relates to an uplink transmission capability of the UE. The UE may transmit, and the network node may receive, a preamble in the selected RO to initiate a RACH procedure. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for guard period configuration between subband full duplex and half duplex symbols and slots. An example method that may be performed at a user equipment (UE) includes obtaining an indication of a guard period during which a cell in which the UE is communicating will switch between subband full duplex (SBFD) communications and half duplex (HD) communications; and performing one or more actions during the guard period, in accordance with the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information indicating that the UE has a capability for an intra-band conflict resolution rule for resolving a conflict, in one or more symbols, between a first communication on a first semi-statically configured resource of a first cell and a second resource on a second cell according to a first priority of the first communication, wherein the first semi-statically configured resource is associated with a first link direction and the second resource is associated with a second link direction different than the first link direction. The UE may perform at least one of the first communication or the second communication according to the intra-band conflict resolution rule. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a multi-cell downlink control information (MC-DCI) that indicates scheduling information for co-scheduled component carriers (CCs), wherein the MC-DCI indicates one or more of an antenna port(s) field or a modulation and coding scheme (MCS) field to be commonly applied to one or more of the co-scheduled CCs. The UE may perform a transmission based at least in part on the scheduling information indicated by the MC-DCI. Numerous other aspects are described.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications. In one aspect, a device, such as a user equipment (UE) may receive a configuration including one or more channel state information (CSI) measurement resources associated with a set of CSI hypotheses. The set of CSI hypotheses may correspond to a set of transmission configuration indicator (TCI) states, or a CSI interference measurement (CSIIM) resource, or both. The UE may select a first CSI measurement resource of the one or more CSI measurement resources for a channel measurement based on a CSI hypothesis of the set of CSI hypotheses. The UE also may select the CSIIM resource or a second CSI measurement resource for an interference measurement based on the CSI hypothesis of the set of CSI hypotheses. The UE may, as a result, transmit a report based on the channel measurement or the interference measurement, or both.
