Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Abstract: An apparatus may receive a media access control (MAC) control element (CE) from a base station (BS) indicating a secondary cell (SCell) to be activated in an unlicensed band. The apparatus may initiate a timer with an end value in response to receiving the MAC CE and may further adjust a radio-frequency (RF) chain from a first state to a second state corresponding to the SCell to be activated. The apparatus may determine, based on measurements of one or more synchronization signal blocks (SSBs) transmitted from the BS indicating one or more listen before talk (LBT) failures corresponding to the SCell, one or more failed SSB transmissions corresponding to the SCell. Accordingly, the apparatus may readjust, in response to expiry of the timer, the RF chain from the second state to the first state and receive one or more additional SSBs in the first state.

Abstract: Techniques described herein include solutions for enabling NR sidelink (SL) communications by using radio resource control (RRC) to provide ser equipment (UEs) with grant configuration (CGs) for unidirectional and/or bidirectional SL communications. These techniques also include solutions for UEs to obtain channel occupation times (COTs) for SL communications, and procedures for sharing COTs with other UEs, and procedures for CG uplink control information (UCI) of physical uplink shared channels (PUSCH) transmissions for NR in the unlicensed spectrum (NR-U). The techniques described herein also include solutions for channel state information (CSI) feedback for CGs of SL in the unlicensed spectrum (CG-Sidelink-U). Also described herein are SL techniques for transmission power control of SL communications and clear channel assessment (CCA) procedures.

Abstract: This disclosure relates to techniques for periodic reference signal activation and deactivation in a wireless communication system. Information configuring periodic reference signals may be received by a wireless device. Information deactivating some or all of the periodic reference signals may be received by the wireless device. The information deactivating some or all of the periodic reference signals may be received using different signaling type than the information configuring the periodic reference signals.

Abstract: Techniques described herein can facilitate Channel-State Information (CSI) measurement and feedback for communication in unlicensed spectrum or Sounding Reference Signal (SRS) transmission and/or channel-state estimation for communication in unlicensed spectrum. In an example, an apparatus is configured to be employed in a User Equipment (UE), and the apparatus comprises a Radio Frequency (RF) circuitry interface and processing circuitry configured to perform CSI measurement for communication in unlicensed spectrum. The apparatus further generates data for feedback according to the CSI measurement, and sends the data for feedback to RF circuitry via the RF circuitry interface. In an example, a frame structure of a data channel begins with a downlink (DL) transmission or soon after an initial signal. In an example, the CSI measurement includes measuring Channel Quality Information (CQI) for one or more sub-bands.

Abstract: Apparatuses, systems, and methods for utilization of an iner-UE coordination message. A UE may receive, from a first UE, an inter-UE coordination message. The inter-UE coordination message may include an indication of a set of resources and an indication of whether the set of resources are preferred resources or non-preferred resources. The UE may be configured to select resources for sidelink communications based on the set of resources indicated in the inter-UE coordination message. The UE may perform differing selection processes based on the set of resources indicated in the inter-UE coordination message. The UE may perform a first process and/or set of processes when the set of resources are indicated as non-preferred and a second process and/or set of processes when the set of resources are indicated as preferred.

Abstract: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.

Abstract: This disclosure relates to techniques for a wireless device to initiate channel occupancy in unlicensed spectrum in a wireless communication system. The wireless device may establish a wireless link with a cellular base station. The wireless device may determine to perform an uplink transmission to the cellular base station on an unlicensed frequency channel. The wireless device may determine whether the cellular base station has channel occupancy of the unlicensed frequency channel. The wireless device may determine whether to initiate channel occupancy of the unlicensed frequency channel. The decision whether to initiate channel occupancy may be based at least in part on whether the cellular base station has channel occupancy of the unlicensed frequency channel.
