Abstract: Example implementations include a method, apparatus and computer-readable medium for wireless communication at a user equipment, comprising receiving a set of messages indicating a first search space for a first downlink control channel and a second search space for a second downlink control channel, wherein the first and second search spaces overlap in a same slot. The implementations further include refraining from performing blind decoding in either the first or the second search space in the same slot, based on a first priority of a first control resource set (CORESET) associated with the first search space and a second priority of a second CORESET the second search space. Additional example implementations relate to a network entity and include configuring for and indicating to a UE a set of non-overlapping (in a same slot) search spaces of different downlink control channels.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node receives one or more request location information messages from a network entity, wherein the one or more request location information messages configure the first network node to use machine learning to derive one or more features of a wireless channel between the first network node and a second network node, and transmits one or more provide location information messages to the network entity, wherein the one or more provide location information messages include the one or more features of the wireless channel, and wherein the one or more features of the wireless channel are derived based on a machine learning model.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may include reflective elements and may reflect signals between a second and third device using the reflective elements. In some cases, the first device may receive signaling from the second device indicating a first subset of the reflective elements corresponding to a first phase configuration and a second subset of the reflective elements corresponding to a second phase configuration. In some other cases, the first device may receive signaling indicating a transmission beam of the second device. Here, the first device may identify the first and second subsets of the reflective elements based on an angle of arrival and departure associated with the indicated transmission beam. In either case, the first device may set the phase configurations of the reflective elements according to the first and second subsets.

Abstract: A mobile device is disclosed. The mobile device may receive, from a network node, information indicative of a predetermined time delay to be utilized in connection with an RF sensing procedure utilizing uplink (UL) and downlink (DL) signals. The mobile device may receive an RF sensing reference signal (RS) transmitted by a base station. Responsive to the predetermined time delay elapsing, the mobile device may transmit a corresponding RF sensing RS at a time corresponding to the predetermined time delay after a time at which the RF sensing RS was received, wherein a time at which the corresponding RF sensing RS is received and the predetermined time delay are usable to determine positioning information of the mobile device.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.

Abstract: In some implementations, an ultra-wideband (UWB) initiator anchor device may receive a first blink message from a mobile device, wherein: the first blink message is sent during a slot of a contention access period (CAP) in a round of a UWB session, and the first blink message comprises a radio frequency (RF) message configured to enable UpLink Time Difference of Arrival (UL-TDoA) measurements by one or more UWB responder anchor devices. The UWB initiator anchor device may transmit a control message from the UWB initiator anchor device indicating a reserved slot in a subsequent contention free period (CFP) of the UWB session, wherein reserving the slot is responsive, at least in part, to receiving the first blink message at the UWB initiator device from the mobile device.

Abstract: In some implementations, a method may comprise determining capabilities of UWB initiator and responder devices related to at least one UWB session. The method may also comprise determining a gap duration based at least in part on the capabilities of the UWB initiator and responder devices for performing RF retuning during the at least one UWB session. The method may also comprise sending a configuration to the UWB initiator and/or responder devices, wherein the configuration is indicative of: a first period of time in the at least one UWB session during which a first portion of the UWB RF signals is transmitted using a first carrier frequency, a gap of at least the determined gap duration following the first period of time, and a second period of time, following the gap, during which a second portion of the UWB RF signals is transmitted using a second carrier frequency.
