摘要： A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

摘要： An apparatus may be configured to determine whether to prioritize a sidelink (SL) logical channel group (LCG) based on an SL prioritization threshold and a UL prioritization threshold, on a condition that a UL prioritization threshold is configured. The apparatus may be configured to determine whether a prioritization value associated with the SL LCG is lower than the SL prioritization threshold. The apparatus may be configured to determine (e.g., at least) whether an uplink (UL) LCG has a prioritization value that is equal to or higher than the UL prioritization threshold. The apparatus may be configured to determine whether to prioritize SL buffer status reporting (BSR) based on a size of a UL grant and the determination of whether to prioritize the SL LCG. The apparatus may be configured to report a buffer status based on the determination of whether to prioritize the SL BSR.

摘要： Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) receiving a first set of one or more initial access signals from a Transmission/Reception Point (TRP), wherein the first set of one or more initial access signals indicates that the TRP is in a dormant state, sending an echo signal to the TRP, wherein one or more transmission parameters of the echo signal are derived from the first set of one or more initial access signals received from the TRP, monitoring for a second set of one or more initial access signals from the TRP after transmitting the echo signal, and receiving the second set of one or more initial access signals, the second set of initial access signals comprising information associated with accessing the TRP. Sets of one or more initial access signals may be received from a plurality of TRPs in an area. The second set of one or more initial access signals may be received from a TRP that is closest to, or has a strongest signal strength for transmitting to, the WTRU.

摘要： Hybrid automatic repeat request (HARQ) timing may be determined. Physical SL feedback channel (PSFCH) resource pool selection may be performed. A source WTRU may (e.g., determine to) signal a PSFCH resource based on channel state information (CSI), transmitter (TX)-receiver (RX) distance, and/or CBR. A destination WTRU may determine sub-channels to include PSFCH resources based on a PSCCH/PSSCH resource and/or WTRU PHY ID information. One or more resource blocks may be determined within a sub-channel for PSFCH transmission based on the WTRU PHY ID and/or a Link ID. A first set of symbols in a slot may be sensed to detect a PSSCH and/or a PSSCH+PSFCH transmission to (e.g., determine to) transmit a PSFCH in the end of the slot without colliding with the PSSCH. A WTRU may switch to a dedicated PSFCH resource pool or Mode 1 transmission upon failure to acquire PSFCH resources in a shared PSFCH resource pool.

摘要： Systems, methods, and devices for sidelink transmit-receive distance related determinations are disclosed herein. In one example, a wireless transmit receive unit (WTRU) may be configured with an associate between range information and zone configuration. The WTRU receive an indication of a specific range information requirement and determine its own zone location based on the configured information and location means (e.g., GPS). The WTRU may also receive zone location information of a transmitting device, and determine the distance between the WTRU and the transmitting device.

摘要： A wireless transmit/receive unit (WTRU) is configured to receive an identifier of a beam. The WTRU is configured to measure a downlink quality associated with at least one beam. The WTRU is configured to determine whether the measured downlink quality is below a threshold value. The WTRU is configured to receive at least one control channel transmission using the beam of the identifier in response to a determination that the measured downlink quality is below the threshold value, wherein the beam used to receive the at least one control channel transmission is a same beam used to receive an associated data channel transmission.

摘要： A receiver bandwidth adaptation for radio access technologies (RATs) may be for a New Radio (NR) or 5G flexible RAT. A WTRU control channel {e.g., receiver) bandwidth may change, for example, based on monitoring a downlink channel for an in indication using a bandwidth (BW) associated with a first BW configuration. The indication may include a signal to change the receiver BW. The WTRU may change the receiver BW associated with the first BW configuration to a second BW configuration when the WTRU receives the indication on a downlink (DL) channel. The WTRU may perform one or more measurements associated with the second BW configuration in response to the change of the receiver BW to the second BW configuration. The WTRU may transmit measurement information to a network entity. The WTRU may receive a DL transmission from the network using the second BW configuration.

摘要： One or more techniques for beamformed paging are disclosed. A transmission/reception point (TRP) may transmit a paging inquiry signal using beam sweeping in a paging inquiry (PI) block with a different time, frequency resource set and/or sequence configuration associated with the same paging occasion (PO), for example, to randomize and/or distribute WTRUs into different monitoring groups. A WTRU may transmit an uplink paging inquiry response indicating a downlink beam for a paging data transmission and/or a WTRU ID. A downlink control and/or a data channel transmission may be triggered by a paging inquiry response transmission. Paging downlink control information may be transmitted in a WTRU-specific control channel, which may contain CRC bits masked by a temporary paging identity, e.g., based on a WTRU ID that may be reported in a paging inquiry response transmission. A WTRU paging procedure may be based on a paging inquiry signal and/or response transmission.

摘要： Methods, apparatus, systems, architectures and interfaces for determining whether sidelink resources of a sidelink radio bearer are available, and for reserving resources of any number of sidelink radio bearers for transmission of periodic data are provided. The method includes determining any of a size, a period, or a pattern of a resource reservation for periodic data that is to be transmitted by the WTRU via the sidelink radio bearer; determining sidelink resources available for transmission of the periodic data via any number of sidelink radio bearers; and transmitting a message including the resource reservation including information indicating reservation of the available sidelink resources for transmission of the periodic data by the WTRU according to any of the size, the period, or the pattern of a resource reservation, wherein the message includes any of a bearer identifier (ID) or Quality of Service (QoS) information.
