Enhancement of logical channel prioritization for sidelink transmission
A method to prioritize sidelink logical channel (SL LCH) during destination UE selection for sidelink Logical Channel Prioritization (LCP) procedure in NR sidelink communication is proposed to avoid resource starvation. A TX UE prioritizes an RX UE having at least one SL LCH that has not satisfied a required minimum bit rate during destination UE selection when allocating SL resource to a new MAC PDU for SL transmission. The TX UE maintains a value Bj for each SL LCH j, where Bj>0 indicates that the logical channel has not met the requirement of prioritized bit rate. If at least one destination UE has SL LCH with data available for transmission and with Bj>0, then the selected destination UE is the one has the highest-priority SL LCH with data available for transmission and with Bj>0.

Method and device for setting resource pool in NR V2X
A method for a first device to perform wireless communication and a device supporting same. The method may include the steps of: receiving, from a base station, a time division duplex uplink-downlink (TDD UL-DL) configuration including information related to a UL resource; receiving, from the base station, information related to the start of sidelink (SL) symbols, information related to the number of the SL symbols, and a bitmap indicating one or more slots included in an SL resource pool; and determining the SL resource pool.
Co-channel co-existence in a wireless communications system
There are provided mechanisms for sharing channels in a wireless communications system among wireless devices that use a plurality of different access technologies. First and second wireless devices are operable to share a channel in the wireless communication system with each other. The first wireless device is operable to provide an indication to the second wireless device that the first wireless device is using a first access technology to access the channel. The second wireless device is operable to receive the indication and determine, based on the indication, that the first wireless device is using a first access technology to access the channel. Accordingly, the second wireless device can determine, based on compatibility of its access technology with that of the first wireless device, whether to refrain from using the channel or to share the channel.
Method and apparatus for performing communication on basis of DCI in NR V2X
A method for performing wireless communication by an apparatus and an apparatus for supporting same are provided. The method may comprise: receiving information related to a plurality of resource pools from the base station; and monitoring a plurality of sidelink (SL) downlink control information (DCIs) related with each of the plurality of resource pools, wherein the plurality of SL DCIs include information for scheduling SL resources on the plurality of resource pools, wherein, before at least one zero bit is appended to the plurality of SL DCIs, a size of a first SL DCI is a largest among sizes of the plurality of SL DCIs, and wherein, based on that the plurality of resource pools are configured for the device, the sizes of the plurality of SL DCIs to which the at least one zero bit is appended are same as the size of the first SL DCI.

Position estimation of a pedestrian user equipment
In an aspect, a UE (e.g., PUE or VUE) performs one or more sidelink positioning measurements on a first sidelink positioning signal between PUE and a VUE. The UE transmits measurement data based on the one or more sidelink positioning measurements to a RSU. The RSU receives the measurement data and determines a positioning estimate for the PUE. The RSU transmits the positioning estimate to the PUE, at least one VUE, or a combination thereof.
Method and apparatus for requesting sidelink transmission resources in a wireless communication system
A method and apparatus are disclosed from the perspective of a first User Equipment (UE) in RRC_CONNECTED to request sidelink resources. In one embodiment, the method transmits a first RRC (Radio Resource Control) message to a network node, wherein a presence of a sidelink QoS (Quality of Service) information list in the first RRC message is optional.

Precision localization of mobile 5G/6G terminals by coordinated GNSS reception
Mobile wireless terminals, such as vehicles in traffic, can determine the relative positions of other vehicles with improved precision by arranging to acquire GNSS (global navigational satellite system) signals simultaneously, and then analyzing the various data sets differentially. Simultaneous acquisition can cancel many important errors such as motional errors of the vehicles, atmospheric distortions, and satellite timebase errors. Differential analysis to determine the relative positions of vehicles (as opposed to their overall geographical coordinates) can reduce errors related to satellite ephemeris and velocity, as well as roundoff errors. Localization with a precision of less than 1 meter can greatly improve collision avoidance while discriminating near-miss scenarios from imminent collisions, according to some embodiments. Messaging examples, in 5G and 6G, to manage the simultaneous acquisition and differential analysis, are provided in examples. Many other aspects are disclosed.
