摘要： An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for 5G-NR sidelink communications, the processing circuitry is to select a time instance n as a resource selection trigger, and perform resource sensing during a sensing window that precedes the time instance n, to obtain a plurality of candidate resources. Resource selection is performed within a resource selection window to select at least one resource from the plurality of candidate resources for a PSSCH transmission to a second UE. The resource selection window starts after the time instance n and ends at a time instance (n+T2), where T2 is a timing value selected based on a sidelink priority value associated with the PSSCH transmission. Data is encoded for the PSSCH transmission using the at least one resource.

摘要： Embodiments of a user equipment (UE) configured for NR V2X sideline selection and reselection are generally described herein. In some embodiments, a selected set of candidate resources are scheduled using a single sidelink control information (SCI) within a scheduling window. In some embodiments, sidelink resources are excluded based on a HARQ round trip time. In some embodiments, sidelink control signalling supports the reservation and indication of multiple sidelink resources.

摘要： An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for 5G-NR sidelink communications, the processing circuitry is to decode SCI received from a second UE via a PSCCH, the SCI indicating a sidelink resource for transmission of a transport block during multiple transmission time intervals, and a PSFCH indicator. A PSSCH is decoded to obtain the transport block, the PSSCH received in one of the multiple transmission time intervals using frequency resource assignment and time resource assignment of the sidelink resource. HARQ feedback information for the decoded PSSCH is encoded for transmission to the second UE using a PSFCH associated with the sidelink resource, based on the PSFCH indicator and a time gap configured by higher layer signaling.

摘要： Devices and systems of sensing, resource selection and control signaling for feedback-less and feedback-based NR-V2X sidelink communication are described. Resource reservation and selection for sidelink retransmissions based on HARQ feedback are described for unicast, groupcast, and broadcast blind retransmissions. After exchanging HARQ feedback capability information for different types of communications, a HARQ-dependent or HARQ-independent resource selection occurs. Look-ahead and/or chain-based resource selection and reservation signaling is used, in which a single resource or some or all of the resources selected are signaled as reserved. Further resource selection of a single additional resource may occur after an initial resource selection. The resource selection for retransmissions may be adapted using a RSRP or distance threshold.

摘要： Technology for traffic offloading to generate a low interference flexible subframe (FlexSF) of an adaptive uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configuration in a heterogeneous network (HetNet) is disclosed. One method can include an evolved Node B (eNB) monitoring a traffic loading metric for a specified traffic loading condition. The eNB can offload traffic scheduled for a packet of a macro user equipment (UE) from a macro cell to a FlexSF of a UL-DL subframe configuration of a small cell when the specified traffic loading condition exists. The eNB can be a macro eNB of the macro cell or a small eNB of the small cell.

摘要： Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.

摘要： A method for cancelling inter-node interference at a victim node is disclosed, which method may be executed as instructions on a machine, where the instructions are included on at least one computer readable medium. The method can include the victim node receiving downlink signal information from an aggressor node. The victim node can estimate a channel impulse response for a channel between the aggressor node and the victim node using the downlink signal information. The victim node can estimate an inter-node interference signal for the channel using the downlink signal information and the channel impulse response. The victim node can receive an uplink signal from a wireless device, wherein the downlink signal information is received prior to the reception of the uplink signal. The victim node can subtract the estimated inter-node interference signal from the uplink signal to form an inter-node interference compensated uplink signal to substantially cancel the inter-node interference from the aggressor node in the uplink signal.

摘要： Technology is discussed to allow transmission points within a Wireless Wide Area Network (WWAN) to adapt to Up Link (UL) and Down Link (DL) traffic demands independently. To mitigate potential interference arising from transmission points scheduled for conflicting UL and DL transmissions, measurements between transmission points can be made to indicate a level of coupling. Based on the various levels of coupling between transmission points, clusters can be formed. Where a high level of coupling is present, transmission points can be included in a common cluster. Where a low level of coupling is present, they can be isolated. Transmission points within the same cluster are scheduled with a common pattern of UL and DL transmissions to avoid interference. Transmission points in different clusters can have different patterns of UL and DL transmission to independently adapt to the relative demands for UL and DL transmissions experienced within these different clusters.
