摘要： Systems, methods, and instrumentalities are disclosed for uplink (UL) transmissions in wireless systems. The systems, methods and instrumentalities may include a wireless transmit/receive unit (WTRU) with a receiver configured to receive one or more uplink (UL) grants that may include allocations associated with a regular UL (RUL) carrier and a supplementary UL (SUL) carrier. The RUL and SUL carriers may be associated with a common downlink (DL) carrier of a serving cell. The WTRU may include a processor configured to select data from one or more logical channels for transmission in accordance with the allocations. The WTRU may include a transmitter configured to transmit data from one logical channel on the RUL carrier and to transmit data from another logical channel on the SUL carrier in accordance with the allocations.

摘要： Methods to perform, maintain and report measurements on a transmission-reception point (TRP) using limited reference signal transmission are described herein. The mobility measurement reports may utilize physical channels. Methods to obtain measurements on neighbor TRPs using limited RS transmissions are also described herein. Random-Access procedures to enable the addition of a neighbor TRP or handover without requiring higher layer signaling (and possibly without an interface between source and target TRP) are also described herein. New triggers to perform RA in order to decrease handover latency are also described herein. Wireless Transmit/Receive Unit (WTRU) behavior upon receiving RAR from multiple possible TRPs are also described herein. For example, a WTRU may store RAR information and use it later in an interrupted RA procedure.

摘要： Methods and systems for operation in a wireless communication system are provided. A first transmission may be initiated using at least a first portion of physical layer resources. A second transmission may be initiated using at least a second portion of the same physical layer resources. The first transmission may be any one of a puncturing transmission, interfering transmission, delay-sensitive transmission, or short transmission. The second transmission may be an on-going transmission or a long transmission.

摘要： A method and apparatus for performing pulse shaping using different windowing functions for different sub-bands of a transmission is disclosed. A method for use in a wireless transmit/receive unit (WTRU) may include the WTRU receiving data symbols. The WTRU may assign the data symbols to a plurality of subcarriers in different sub-bands and map the data symbols on each of the plurality of subcarriers in the different sub-bands to a plurality of corresponding subcarriers of an inverse fast Fourier transform (IFFT) block. The WTRU may take an IFFT of the block for each sub-band and pad an output of the IFFT block with a prefix and a postfix for each sub-band. The WTRU may apply a windowing function to an output of the padding for each sub-band and form a composite signal for transmission by adding an output of the windowing of each sub-band. The WTRU may transmit the signal.

摘要： A wireless transmit/receive unit (WTRU) may receive, from a serving cell based on the measurement report, a conditional reconfiguration message that includes a trigger condition and configuration information for handover to a target cell based on the trigger condition. The conditional reconfiguration message may be stored and the WTRU monitors trigger quantities of the serving cell and the target cell for the trigger condition being met. When the trigger condition is met within a validity period, then the WTRU applies the received configuration information and starts the handover to the target cell.

摘要： In an integrated access and backhaul (IAB) system, an access WTRU may receive a random access channel (RACH) occasion (RO) configuration comprising one or more RO resources from a first integrated access backhaul (IAB) node. The access WTRU may receive an indication that one or more of the configured RO resources have an overlap with one or more IAB node RO resources. The access WTRU may monitor and receive the ROI indicating the configured RO resources that overlap with the one or more IAB node RO resources. Based on the received ROI and the configured RO resources, the access WTRU may determine one or more RO resources available for PRACH transmission. The access WTRU may select an RO resource from the available RO resources for PRACH transmission. The access WTRU may send a first PRACH transmission to the first IAB node using the selected RO resource.

摘要： Systems, methods, and instrumentalities are described herein that may be associated with SS block (SSB) timing acquisition (e.g., for new radio unlicensed (NR-U) operations). A wireless transmit receive unit (WTRU) may detect/decode an SSB. The WTRU decoding the SSB may include the WTRU decoding a PBCH payload. The PBCH payload may be scrambled with a first scrambling code, channel coded, and scrambled with a second scrambling code. The WTRU may acquire information associated with the SSB that includes one or more of: a transmission occasion time index, a block time index, or a time offset. The WTRU may use one or more of the acquired parameters to determine a timing associated with the SSB.

摘要： Systems, methods, and instrumentalities are disclosed for interleaving coded bits. A wireless transmit/receive unit (WTRU) may generate a plurality of polar encoded bits using polar encoding. The WTRU may divide the plurality of polar encoded bits into sub-blocks of equal size in a sequential manner. The WTRU may apply sub-block wise interleaving to the sub-blocks using an interleaver pattern. The sub-blocks associated with a subset of the sub-blocks may be interleaved, and sub-blocks associated with another subset of the sub-blocks may not be interleaved. The sub-block wise interleaving may include applying interleaving across the sub-blocks without interleaving bits associated with each of the sub-blocks. The WTRU may concatenate bits from each of the interleaved sub-blocks to generate interleaved bits, and store the interleaved bits associated with the interleaved sub-blocks in a circular buffer. The WTRU may select a plurality of bits for transmission from the interleaved bits.

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.
