摘要： For SL resource allocation, the Rx UE assisted resource allocation mechanism can be applied to improve the reliability and reduce the overall latency for SL communication, which can work independently or jointly with Tx UE based sensing and resource allocation mechanism. Rx UE can be triggered to send the feedback information upon reception of the SCI and/or data from the Tx UE. The feedback information can carry Rx UE's resource sensing information, CSI info, observed Doppler/delay/moving speed related information and MIMO related feedback information to assist the resource/MCS/MIMO/DMRS pattern selection at Tx UE. It is desirable for Rx UE to feedback such assistance information (just) before the reserved resources by Tx UE to be transmitted. So the Tx UE can take into account the feedback information to assist resource re-selection and/or resource utilization.

摘要： A receive (Rx) UE performs blind detection to decode a first-stage Sidelink Control Information (SCI) in a received signal. The first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE. The time-and-frequency resources are used to transmit the first-stage SCI and a second-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH. The Rx UE locates the second-stage SCI in the time-and-frequency resources based on the first-stage SCI. The second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication. The Rx UE decodes the second-stage SCI using at least in part an identifier which identifies the Rx UE as a destination of the received signal.

摘要： In one novel aspect, a plurality of synchronization signal (SS) anchors within a block of a contiguous spectrum is configured in a wireless network, wherein each SS anchor is a primary SS anchor or a secondary SS anchor. The UE performs an initial access by detecting a first primary SS anchor and receives one or more virtual carrier configurations with corresponding SS anchors within the block of the contiguous spectrum. In another novel aspect, The UE performs an initial access through a first RF band with a first bandwidth and a first center frequency, receives a switching signal to switch from the first RF band to a second RF band with a second bandwidth and a second center frequency, wherein the second bandwidth is different from the first bandwidth, and performs a RF bandwidth adaptation from the first RF band to the second RF band based on the adaptation signal.

摘要： A method for allocating sidelink resource is provided. The method is applied to a first UE in a sidelink communication to transmit signal to a second UE which is a peer receiving (peer-Rx) UE of the first UE. The method includes the steps of maintaining, a counter to record how many remaining periodic reservations of sidelink resource to be used for sidelink signal transmission, wherein the periodic reservations are associated with a reservation period; receiving, in the sidelink communication, assistance information from the second UE or from a third UE which is not the peer-Rx UE of the first UE; and determining, whether to reselect a new sidelink resource different from the sidelink resource comprising the remaining periodic reservations according to the receiving assistance information even if the counter is greater than 0, to transmit signal to the second UE.

摘要： Apparatus and methods are provided to support discontinuous channel/SCI monitoring (DRX) over Sidelink in mobile communication system. In one novel aspect, each UE determines his own SL DRX configuration and exchange it with peer UE, wherein the SL DRX configuration includes the transmission pattern or the reception pattern a UE expects to transmit or receive. Based on the exchange of SL DRX configuration, a UE can then decide when to transmit data to each peer UE for each groupcast/broadcast service, and when to keep awake to monitor for possible SL data reception. In another novel aspect, the concept of wake-up or go-to-sleep signaling is introduced, in which the resource for wake-up or go-to-sleep signaling can be configured per transmitter UE, per receiver UE, or per link. The receiver UE can then determine whether to keep awake or not during the DRX reception pattern.

摘要： Various solutions for handling synchronization signal block with respect to user equipment (UE) and network apparatus in mobile communications are described. A UE may receive a synchronization signal block (SS block) from a network apparatus. The UE may detect a transmission beam of the network apparatus according to the SS block. The SS block may comprise a first synchronization signal, a second synchronization signal and a reference signal for detecting the transmission beam. The first synchronization signal may be a primary synchronization signal (PSS), the second synchronization signal may be a secondary synchronization signal (SSS), and the reference signal may be a demodulation reference signal (DMRS). The SS block may further comprise a broadcast channel and wherein the DMRS is used for demodulation of the broadcast channel.

摘要： This disclosure relates generally to wireless communications, and, more particularly, to methods and apparatus about resource allocation for SL. For SL resource allocation, the Rx UE can transmit the assistance information to assist Tx UE's resource selection. For the reserved resource indicated in SCI from the peer Tx UE, the Rx UE can indicate the resources are not preferred via the signaling, e.g., one bit in the physical SL feedback channel (PSFCH) to the peer Tx UE ifthe reserved resources are not preferred based on the sensing results at Rx UE. On the other hand, the Rx UE can transmit at least SCI carrying resource reservation information from the peer Tx UE at least to the potential interfering UEs for resource collision avoidance ifthe reserved resources is preferred/acceptable based on the sensing results at Rx UE.

摘要： Various examples and schemes pertaining to shared negative acknowledgement (NACK) for groupcast and multicast in New Radio (NR) vehicle-to-everything (V2X) communications are described. An apparatus as a source user equipment (UE) transmits data to two or more destination UEs of a plurality of destination UEs via groupcast or multicast with hybrid automatic repeat request (HARQ). The apparatus then receives a NACK on a single time-frequency resource from at least one of the two or more destination UEs. The single time-frequency resource is shared by the plurality of destination UEs to transmit the NACK to the source UE.
