Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify an active state of a first sidelink (SL) discontinuous reception (DRX) cycle of the first UE and an active state of a second SL DRX cycle of a second UE. The first UE may transmit, to the second UE based at least in part on an overlap between the active state of the first SL DRX cycle and the active state of the second SL DRX cycle, an indication associated with adjusting the first SL DRX cycle or the second SL DRX cycle. Numerous other aspects are described.

Abstract: 本公开涉及一种直连通信方法和装置，其中，所述直连通信方法包括：在所述第一终端基于直连链路Sidelink与目的地址进行直连通信时，确定是否忽略Sidelink非连续接收DRX的限制。根据本公开，终端不是在任何情况下都采用Sidelink DRX的方式进行直连通信，而是根据实际情况确定是否忽略Sidelink DRX的限制。一方面，可以避免Sidelink DRX导致的不必要的数据延迟；另一方面，也可以避免发送端与接收端对Sidelink DRX的使用不匹配而导致的数据丢失。

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LET) channel access procedure in the TTIs, and transmitting at least one LET report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: A user device, UE, for a wireless communication system, is described. The UE may transmit and/or receive over a sidelink, SL, in the wireless communication system. Responsive to detecting one or more collisions on one or more resources used or reserved to be used by a further UE for one or more transmissions over the SL, the UE may transmit a collision indication, Cl (404), and an assistance information (406), like an assistance information message, AIM, the assistance information indicating one or more preferred and/or not preferred resources for a transmission by the further UE.

Abstract: A network node, a wireless communication device and methods therein for monitoring interferences between a number of groups of wireless communication devices and configuring SL resources for the number of groups of wireless communication devices in a wireless communication network are disclosed. The network node configures a discovery signal associated with an identity and configures which wireless communication devices in which groups to transmit and/or receive the configured discovery signal. The network node determines whether the number of groups of wireless communication devices (130, 131, 132, 140, 141, 142) are isolated from each other based on a report related to the discovery signal and decides whether or not to reconfigure the SL resources for the number of groups or rearrange the wireless communication devices in the groups based on the determined result on whether the number of groups of wireless communication devices (130, 131, 132, 140, 141, 142) are isolated from each other.

Abstract: 本公开提出一种传输资源选择方法、装置、通信设备、存储介质和产品，属于无线通信技术领域。其中，该方法包括：发送端用户设备根据接收端用户设备的非连续接收DRX设置，确定向接收端用户设备发送的直连传输所使用的时间频率传输资源。由此，发送端UE根据接收端UE的DRX设置进行资源选择，可以使得所选择的时间频率传输资源处于接收端UE的DRX周期中的激活期内，从而保证发送端UE在接收端UE处于激活态时发送直连传输，由此，可以避免接收端UE无法接收到数据，而造成数据丢失的情况。

Abstract: Aspects relate to direct current (DC) tone indication on the sidelink. A wireless communication device (e.g., a UE) may transmit an indication of its sidelink DC tone to one or more other UEs via respective sidelinks. In an example, a transmitting UE may transmit an indication of its sidelink DC tone within second stage sidelink control information included within a data region of a slot. A receiving UE may further transmit an indication of its sidelink DC tone to a transmitting UE over a sidelink between the transmitting UE and receiving UE or a base station in wireless communication with the transmitting and receiving UEs may provide the indication of the sidelink DC tone of the receiving UE to the transmitting UE.
