The present application relates to devices and components including apparatus, systems, and methods for partial sensing for resource selection, reevaluation, and preemption. In some embodiments: a UE receives configuration information for a resource pool; determines a type of traffic to be transmitted by the UE, the type to include aperiodic traffic or periodic traffic; determines, based on the configuration information and traffic type, first and second values to define a window for contiguous partial sensing; and performs contiguous partial sensing within the window.

Partial sensing for resource selection, reevaluation, and preemption

A technique for wireless communications in a wireless system including: transmitting, from a second user device, unlicensed frequency transmission capability information, receiving an uplink transmission time for the second user device based on the unlicensed frequency transmission capability, receiving, at the second user device, a request to transmit a reservation transmission in an unlicensed frequency band based on a cancellation time capability of a first user device and the uplink transmission time, transmitting, by the second user device, the reservation transmission in the unlicensed frequency band, and transmitting, by the second user device, a higher priority uplink transmission in the unlicensed frequency band.

Techniques for channel access by a user device with uplink (UL) cancellation in unlicensed bands

Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing uplink communications and vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a sidelink acknowledgment message over a sidelink feedback channel. The wireless device receives a resource grant through a downlink control channel, wherein the resource grant specifies one or more second time slots for the wireless device to transmit an uplink transmission over an uplink channel. The first and second time slots at least partially overlap, and it is selectively determined whether to transmit the sidelink acknowledgment message or the uplink transmission during the overlapping time slots.

Slot aggregation and selective prioritization for uplink and sidelink feedback communications

Apparatuses, systems, and methods for a wakeup radio in a wireless communication system, e.g., in 5G NR systems and beyond. An RRC state is introduced to support a wakeup radio/, including defining transition mechanisms to/from existing RRC states. Further, signaling is introduced to activate a wakeup radio/activate an RRC low power state. Additionally, a bandwidth part framework for a wakeup signal is defined in which a base station may configure one or more time/frequency resources or a wakeup signal for a wakeup radio. In addition, various mechanisms are introduced to switch a wakeup radio on as well as to switch a wakeup radio off. Also, mechanisms are introduced for multiplexing multiple wakeup signals in a time/frequency resource, configuring a wakeup signal bandwidth, and configuring which beam a wakeup signal may be received on.

Radio wakeup radio

A base station is configured to determine a sounding reference signal (SRS) configuration that has a plurality of cyclic shifts for a comb 8 SRS, a plurality of user equipment (UE) ports for transmitting the comb 8 SRS and a mapping of the plurality of cyclic shifts to the plurality of UE ports. The base station is further configured to transmit the SRS configuration to the UE.

SRS signaling in 5G new radio wireless communications

Systems and methods are provided for to support user equipment (UE) channel state information (CSI) report of time domain channel properties. Embodiments herein consider Uplink Control Information (UCI) multiplexing, UCI omission, Interference Measurement Resource (IMR) configuration, and phase continuity handling. A channel state information report configuration (CSI-ReportConfig) may comprise details regarding measurement and reporting of time domain channel properties (TDCP) based on channel state information reference signal (CSI-RS) for tracking reference signal (TRS).

Method and apparatus to support UE CSI report of time domain channel properties

This disclosure relates to techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals for multi-transmission-reception-point operation in a wireless communication system. A wireless device may establish wireless links with multiple transmission-reception-points of a cellular network. The wireless device may receive downlink control information. The wireless device may determine a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information. Signals received according to the quasi-co-located assumption for aperiodic channel state information reference signals may be buffered by the wireless device if a scheduling offset for the downlink control information is below a scheduling offset threshold.

Quasi-co-located assumption for aperiodic CSI-RS for multi-TRP operation

A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Systems and methods for controlling radio-frequency exposure

In an example method, a user equipment (UE) device receives a slot of data from a base station (BS). The UE device determines a quality of a wireless channel between the BS to the UE device, including determining (i) a metric for a interval extending from a sequentially first symbol of the slot of data to a symbol immediately preceding the first subset of symbols, (ii) a metric for an interval extending from the sequentially first symbol of the slot of data to a sequentially last symbol of the first subset of symbols, (iii) a metric for an interval extending from the sequentially first symbol of the slot of data to a symbol immediately preceding the second subset of symbols, and/or (iv) a metric for an interval extending from the sequentially first symbol of the slot of data to a sequentially last symbol of the second subset of symbols.

Technologies in multi-PDSCH transmission in a wireless network

Systems and methods of a wireless communications system using signals not traditionally used for positioning purposes for positioning measurements in both uplink (UL) and downlink (DL) are described herein. A user equipment (UE) may generate a UE capability information message indicating one or more signal types that the UE can process for DL positioning measurements and/or that the UE can send for UL positioning measurements. The one or more signal types so indicated may include signals not traditionally used for positioning measurements. The UE may send, to the base station, the UE capability information message. The wireless communications system may then configure the base station and/or the UE to use such signal types with one or more positioning methods. In some embodiments, the base station may also indicate to the UE a subset of signals of an indicated type which should be processed for DL measurements/sent for UL measurements.

Using non-positioning signals for positioning in downlink and/or uplink

A user equipment (UE) is configured to perform channel estimation. The UE operates in a current channel estimation mode comprising either one of a first mode or a second mode, wherein the first mode comprises receiving first reference signals (RS) having a first RS overhead and wherein the second mode comprises receiving second reference signals (RS) having a second RS overhead, receives a network indication to switch from the current channel estimation mode to a new channel estimation mode comprising the other one of the first mode or second mode, transmits an acknowledgment to the network that the network indication was received and switches from the current channel estimation mode to the new channel estimation mode in accordance with the network indication.

Channel estimation using artificial intelligence

Various manners of reporting channel state information (CSI) measurements in a multiple transmission and reception point (multi-TRP) configuration are provided. A UE may perform channel state information (CSI) measurements for a channel measurement resource (CMR) for the first gNB and at least one interference measurement resource (IMR) for the at least one second gNB, determine a configuration for a CSI report for the CSI measurements including a channel quality indicator (CQI) measurement for the CMR and the at least one IMR and transmit the CSI report to at least one of the first gNB and the at least one second gNB.

Channel state information report for multi-TRP operation

Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.

Enhanced CSI reporting for multi-TRP operation

A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Full power uplink transmission enhancement

Systems and methods provide a channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A user equipment (UE) triggers measuring of a CSI reference signal (CSI-RS) from a base station. The UE triggers measuring of a DMRS for a PDSCH transmission from the base station. The UE generates a CSI report to report the CSI measurement, based on both the CSI-RS and the DMRS for the PDSCH transmission. The UE may then send the CSI report to report the CSI measurement to the base station.
