Abstract: A method of wireless communication performed by a first transmission device incudes receiving a first set of observations from a first receiving device based on transmissions from the first transmission device to the first receiving device at a previous time slot of a fixed contention-based spectrum sharing system. The first transmission device shares a spectrum with a second transmission device. The method also includes measuring an energy level from an ongoing data transmission of the second transmission device at a current time slot. The method further includes generating, at an artificial neural network of the first transmission device, at least one of a transmission determination, a set of transmission parameters, or a combination thereof, based on a second set of observations, the energy level, and a counter. The method also includes transmitting, to the first receiving device, during the current time slot based on at least one of the transmission determination, the set of transmission parameters, or the combination thereof.

Abstract: A method of measuring a wireless OFDM PRS at a user equipment includes: selecting a symbol subset of a symbol group of the OFDM PRS, the OFDM PRS comprising a slot of symbols comprising the symbol group, the symbol group consisting of a first symbol quantity of consecutive ones of the symbols, the symbol group being fully staggered in frequency domain, the symbol subset consisting of a second symbol quantity of the symbols of the symbol group, the second symbol quantity being smaller than the first symbol quantity, and the symbol subset being less than fully staggered in the frequency domain; and measuring the symbol subset without measuring all of the symbols of the symbol group.

Abstract: In an embodiment, a UE transmits an on-demand PRS request for PRS(s) on selected frequency-domain resource(s) (e.g., frequency layer, frequency band, CC, etc.). In another embodiment, a UE receives, from a network component (e.g., BS, core network component, LMF, location server, etc.), configuration of frequency-domain resources (e.g., frequency layer, frequency band, CC, etc.), wherein each frequency-domain resource configuration is associated with a bandwidth and SCS. The UE further receives, from the network component, configuration of PRS(s), wherein each PRS is associated with a single frequency-domain resource from the frequency-domain resources. The UE determines a single reference TRP for each of the frequency-domain resources, performs PRS measurements on the PRS(s), and determines positioning measurements at least based on the PRS measurements and the determined reference TRPs.

Abstract: In an embodiment, a UE determines a maximum duration to which a UE shall remain active after a DRX ON period to transmit and/or process one or more reference signals for positioning associated with a positioning session. The UE transmits an indication of the maximum value to a BS. The UE and the BS each selectively transmit and/or process the one or more reference signals (e.g., DL PRSs and/or UL SRS-Ps) based at least in part upon the maximum duration.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving first downlink information, failing to decode a first portion of the first downlink information, transmitting, to a base station (BS), a first response including a negative acknowledgement (NACK) indicating a first decoding failure associated with the first portion of the first downlink information, receiving second downlink information, failing to decode a first portion of the second downlink information, detecting a hybrid automatic repeat request (HARQ) buffer unavailability, determining to discard NACK information associated with the NACK, resetting at least a portion of a HARQ buffer, in response to detecting the HARQ buffer unavailability, by discarding NACK information associated with the NACK, generating a reset NACK indicating the HARQ buffer reset and indicating the NACK information being discarded, and transmitting a second response including the reset NACK to the BS.

Abstract: In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.

Abstract: A configuration to allow for scheduling communication with a UE having associated characteristics based on a timing indication. The apparatus receives, from a UE, a timing indication associated with a bandwidth, a subcarrier spacing, or a waveform. The timing indication identifying a delay duration based on a processing timeline for the UE. The apparatus receives from the UE, or transmits to the UE, a first data channel having the bandwidth, the subcarrier spacing, or the waveform scheduled based on the timing indication. The first data channel is transmitted or received at a first time based on the timing indication.

Abstract: The present disclosure relates to apparatus and methods of monitoring a region by a transmitting device within a wireless medium for transmissions using at least one directional beam covering the region. Upon determining that the region in the wireless medium is free of transmissions, the transmitting device transmits to a plurality of wireless devices in the region using a plurality of spatially separated directional beams. Other aspects of the disclosure relate to apparatus and methods for receiving an instruction, e.g., at a user equipment (UE), to perform a channel assessment at a first time. The UE monitors a region within a wireless medium for transmissions after receiving the instruction. Upon determining that the region is free of transmissions, the UE may send an acknowledgment of the received instruction

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a synchronization signal block (SSB) within a discovery reference signal (DRS) transmission window that includes more than 64 candidate SSB positions, determine an index value of the SSB based at least in part on an indexing scheme for SSBs that are included in the DRS transmission window, wherein the indexing scheme includes one of a consecutive indexing scheme or a non-consecutive indexing scheme; and determine a cell timing based at least in part on the index value. Numerous other aspects are described.
