Abstract: Wireless communications systems and methods related to frequency resource reservation for sidelink communication over a shared radio frequency band are provided. A first user equipment (UE) senses in a sidelink resource pool within a shared radio frequency band. The first UE reserves, based on the sensing, a frequency resource of the sidelink resource pool within an instance of a variable time range. The first UE performs, in the shared radio frequency band, one or more listen-before-talks (LBTs). The first UE transmits, to a second UE based on the one or more LBTs, a sidelink transmission using the frequency resource within the instance of the variable time range.

Abstract: Some aspects described herein relate transmitting, to a receiving UE, a sidelink control information (SCI) that schedules multiple transport blocks (TBs) of shared channel communications in multiple time divisions, and transmitting, to the receiving UE and based on the SCI, the multiple TBs of shared channel communications in the multiple time divisions. Other aspects relate to receiving, from a transmitting UE, a SCI that schedules multiple TBs of shared channel communications in multiple time divisions, and receiving, from the transmitting UE and based on the SCI, the multiple TBs of shared channel communications in the multiple time divisions. Additional aspects relate to configuring the UEs in this regard.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications in narrowband frequency bands using frequency hopping. In some implementations, a base station (BS) groups a plurality of hopping channels of a frequency hopping pattern into a number of groups based on a bandwidth part (BWP) hopping frequency of each hopping channel of the frequency hopping pattern. The BS transmits indications of the frequency hopping pattern and the grouping of hopping channels to user equipments (UEs). The BS transmits a channel state information reference signal (CSI-RS) on a first hopping channel, and receives channel state information (CSI) of the first hopping channel from one or more of the UEs. In some other implementations, a UE receives indications of the frequency hopping pattern and hopping channel groups, and determines CSI of the first hopping channel based on the received CSI-RS. The UE may transmit the CSI to the BS.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a configuration including a set of signature waveforms for a micro-sleep mode of operation in shared spectrum, and may transmit the configuration to at least one user equipment (UE) served by the base station. Additionally, a UE may receive a configuration including a set of signature waveforms for a micro-sleep mode of operation in shared spectrum. The UE may detect at least one signature waveform of the set of signature waveforms, and in response to detecting the at least one signature waveform, operate in the micro-sleep mode for a period of time.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support chained sidelink transmissions. A transmitting user equipment (UE) may send, to a receiving UE, sidelink control information (SCI) that reserves resources for transmission from the transmitting UE as well as reserves resources for a response transmission from the receiving UE. The receiving UE may respond with a transmission using the resources that were reserved in the SCI and without sending its own SCI to reserve resources for the response. The latency between the transmitting UE sending the first transmission and receiving a response from the receiving UE may be reduced, because the transmitting UE reserved the resources for itself and the receiving UE with the same SCI.

Abstract: Certain aspects of the present disclosure provide techniques for sending a configuration for conditional configured grant (CG) occasions for uplink transmission to a user equipment (UE). Each conditional CG occasion may be associated with multiple conditional CG resources. Each conditional CG resource may be associated with a sending window. The UE may monitor within sensing windows for conditional CG resources of a certain conditional CG occasion for over the air (OTA) signals from other UEs to determine if the conditional CG resources are available for uplink transmission. The UE may skip the conditional CG occasion when the conditional CG resources are not available. The UE may perform uplink transmission on the conditional CG resources when the conditional CG resources are available.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may belong to a group of UEs that includes at least a second UE and a third UE. The first UE may perform a channel access procedure and, when the channel access procedure is successful, may transmit a first positioning reference signal (PRS) over a sidelink communication link to the second and third UEs. The first UE may transmit the first PRS during a first time interval of a transmission window. Based on receiving the first PRS, the second UE may perform a channel access procedure and may transmit a second PRS to the first UE during a second time interval of the transmission window. The second PRS may be multiplexed (e.g., using frequency division multiplexing (FDM) or code division multiplexing (CDM)) with at least a third PRS transmitted by the third UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to discontinuous reception (DRX) extended-on operations and dynamic transmission patterns in sidelink are provided. A first user equipment (UE) determines a transmission pattern for a first sidelink based on an extended DRX on-duration associated with a second sidelink different from the first sidelink, wherein the first sidelink is between the first UE and a second UE, and wherein the second sidelink is between the second UE and a third UE. The first UE transmits, to the second UE over the first sidelink during the extended DRX on-duration based on the transmission pattern, a communication signal.

Abstract: Sub-resource pools for transmission of new radio (NR) sidelink (NR SL) over unlicensed bands is disclosed. A user equipment (UE) capable for sidelink communications may receive a sidelink configuration message from a serving base station that includes identification of a plurality of channel access types associated with a plurality of sub-resource pools for autonomous sidelink access of a shared communication channel. The UE may obtain information for a sidelink transmission over a transmission resource pool allocated for the autonomous sidelink access and determine the plurality of sub-resource pools from available resources within the transmission resource pool according to a channel access type of each resource, wherein each sub-resource pool includes a subset of resources associated with a corresponding channel access type. The UE may then select a sub-resource pool for sidelink transmission and transmit the information on a transmission resource selected from the sub-resource pool.
