摘要： An apparatus and a method are disclosed for wireless communication with an external device. The apparatus may be a user equipment (UE) provided for wireless communication with an external device. The UE includes a transceiver and a processor. The processor is configured to receive, via the transceiver, a radio resource control (RRC) signal; determine a virtual bandwidth part (vBWP) based on the RRC signal, the vBWP including a plurality of narrowband (NB) bandwidth parts (BWPs) in a carrier bandwidth for the UE to perform communication at a given time instance, and determine a bandwidth location in the carrier bandwidth of at least one of the plurality of NB BWPs. If a first relative frequency of the bandwidth location in a first NB BWP is the same as a second relative frequency of a bandwidth location in a second NB BWP, then information included in downlink control information (DCI) is re-used to identify the bandwidth location.

摘要： Disclosed is a method including identifying, for a transmission between a user equipment (UE) and one or more neighboring UEs, one or more interfering UEs of the one or more neighboring UEs by determining potential collisions between candidate resources identified by the UE and resources selected by the one or more neighboring UEs based on beam information, location information of the UE, measured signal strength, and resource reservation information, and excluding resources reserved by the one or more interfering UEs from a resource selection window.

摘要： A system and a method are disclosed for beam refinement to enable inactive mode transmission in frequency range 2 for 3GPP RedCap devices. A RedCap device receives system information in a SIB1 from a wireless network in which the SIB1 includes information relating to an indication of resources used to transmit a SIB-x. The device receives the SIB-x, which includes an indication of at least one resource, at least one configuration for a Downlink-Reference Signal (DL-RS) transmission, and information relating to a measurement report relating to the beam-refinement measurement that is to be performed by a device. The device receives the DL-RS transmission from the wireless communication network, performs the beam-refinement measurement, and sends a measurement report to the wireless network. Subsequent to sending the measurement report, the device sends an enhanced transmission to the wireless network based on the measurement report.

摘要： A system and a method are disclosed for accessing a wireless medium for a NR-U deployed at 60 GHz. A directional CCA sensing is performed on a set of multiple beams in the medium in which each beam is oriented in a different direction. It is determined whether at least one beam of is busy and, if so, a back-off timer is initialized. The back-off timer is decreased by a predetermined amount based on a determination that all beams of the set of multiple beams are idle. The back-off timer is repeatedly decreased the predetermined amount based on a determination that all beams of the set of multiple beams are idle until the back-off timer equals a predetermined amount. Data is transmitted at least one beam of the set of multiple beams based on the back-off timer equaling the predetermined amount.

摘要： Systems and methods for sidelink transmission. In some embodiments, a method includes: determining, by a User Equipment (UE), a measure of channel congestion, the measure of channel congestion being a channel busy ratio or a channel occupancy ratio; determining, by the UE, a determined contention window size, based on the measure of channel congestion; and waiting, during a first interval of time, without making a sidelink transmission, wherein a length of the first interval of time is based on the determined contention window size.

摘要： A system and a method are provided for enhanced channel state information (CSI) reporting. A user equipment (UE) generates CSI based on each of a plurality of power offsets. The UE transmits the CSI measurements in a CSI report to a base station (gNB). The UE receives, from the gNB, an indication of a channel state corresponding to a power offset of the plurality of offsets. Based on the indication of the channel state, the UE uses one or more particular resources to receive a physical downlink shared channel (PDSCH).

摘要： A system and a method are disclosed for determining, by a targeted receiving User Equipment (UE), that a corresponding transmitting UE has a future reserved resource block. The receiving UE may perform a Listen Before Talk (LBT) sensing to identify a time period when an unlicensed channel is unoccupied and can be used by the corresponding transmitting UE for the future reserved sidelink transmission. The receiving UE may transmit a reservation signal for the unlicensed channel to the corresponding transmitting UE, during at least a portion of the time period when the unlicensed channel is unoccupied. Further, the receiving UE may, switch, to a receiving mode prior to or at a reserved slot boundary of the future reserved resource block.
