An apparatus and method for handling in-device co-existence of NR V2X and LTE V2X sidelinks are disclosed. The apparatus includes a transceiver that is scheduled to transmit and/or receive a first data transmission over a first radio access technology (RAT) and a second data transmission over a second RAT; and a processor that detects collision between the first data transmission and the second data transmission; wherein, upon detection of collision, the processor further controls the transceiver to selectively drop one of the data transmissions based on a set of selection criteria, the set of selection criteria including: priorities of the first RAT and the second RAT, and an attribute of the second data transmission indicative of whether it is an initial transmission or a retransmission.

Various schemes pertaining to encoding and transmit power control for downsized trigger-based (TB) physical-layer protocol data unit (PPDU) transmissions in next-generation WLAN systems are described. A station (STA) receives a trigger frame indicating an allocated resource unit (RU) of a first size. The STA performs channel sensing responsive to receiving the trigger frame. In response to detecting at least one subchannel being busy from the channel sensing, the STA performs a downsized trigger-based (TB) transmission with a downsized RU or multi-RU (MRU) of a second size smaller than the first size by utilizing downsized RU or MRU allocation information while maintaining a value of each of one or more parameters unchanged in an encoding process to perform the downsized TB transmission.

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to group transmissions into one or more groups, e.g., of various priority levels and/or types of transmissions. The UE may resolve collisions, e.g., according to one or more procedures described herein. The UE may transmit the transmissions according to the resolutions.

In one aspect, a method of wireless communication includes receiving, by a first user equipment (UE), a first transmission from a second UE for a new radio (NR) sidelink channel. The method also includes receiving, by the first UE, a second transmission from a third UE for the sidelink channel. The method further includes transmitting, by the first UE, a feedback transmission based on a medium contention event for the first and second transmissions of the NR sidelink channel and on a range condition.

In one aspect, a first device includes a transceiver configured to communicate with a second device via a wireless link. In one aspect, the first device includes a processor configured to determine that a type of content to be transferred between the first device and the second device through the wireless link. In one aspect, the processor is configured to modify one or more parameters for the first device to access the wireless link, from a first set of values to a second set of values, in response to determining that the type of content is artificial reality. In one aspect, the processor is configured to cause the transceiver to access the wireless link using the second set of values.

A channel detection method can be applied to a base station operating on an unlicensed spectrum, and include: detecting that a first uplink transmission is not successfully performed; determining a target channel detection mechanism for performing channel detection for a first downlink transmission, wherein the first downlink transmission represents a next downlink transmission following the first uplink transmission; and performing the channel detection for the first downlink transmission based on the target channel detection mechanism. Therefore, it can be specifically selected that which channel detection mechanism to use according to actual conditions, thereby improving the accuracy and efficiency of channel detection.

The present specification provides a method for handling a collision between a demodulation reference signal (DMRS) and a channel state information-reference signal (CSI-RS) in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving a DMRS from a base station; receiving a CSI-RS from the base station; and when a collision between the DMRS and the CSI-RS occurs on at least one resource element (RE), puncturing a resource associated with the DMRS, or a resource associated with the CSI-RS on the basis of time domain behavior of the CSI-RS.

Embodiments of a device and method are disclosed. In an embodiment, a physical layer (PHY) device that is compatible with the IEEE 802.3 standard and that utilizes carrier-sense multiple access with collision detection (CSMA/CD) for media access control to a shared media is disclosed. The PHY device includes a physical coding sublayer transmitter (PCS-TX), a physical medium attachment transmitter (PMA-TX), a physical coding sublayer receiver (PCS-RX), a physical medium attachment receiver (PMA-RX), and a media access priority manager configured to initiate transmission of an indication of a priority of a frame that is to be transmitted onto the shared media.

Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A control device can monitor UWB ranging between a mobile device and a primary anchor. In response to determining that a signal strength between the mobile device and the primary anchor is below a threshold, the control device can identify anchors for which the mobile device has had a signal strength above the threshold during a period of time, and select one of the anchors as a new primary anchor for the mobile device. For example, the control device can select the new primary anchor based on a relative collision tolerance mapping for the new primary anchor and at least one other anchor within a UWB range of the new primary anchor. The control device can send a command causing UWB ranging to be performed between the mobile device and the new primary anchor.
