    摘要: The system and method includes PRS scheduling, SL-PRS request and transmission. PRS measurement and report, and autonomous positioning transmission and reporting. The system and method for a WTRU to provision sidelink positioning includes configuring the WTRU with a sidelink positioning service and an associated destination identification (ID), receiving DL-PRS and measurement reporting configuration from a network, transmitting an SL (sidelink)-PRS (positioning reference signal) transmission/reception request using the destination ID to at least one other WTRU requesting the at least one other WTRU to transmit SL-PRS, the request including at least one parameter based on the received measurement reporting configuration and QoS of a positioning service, and performing a PRS measurement and reporting the measurement to the network.

    摘要: Method, apparatus, and systems for hybrid automatic repeat request (HARQ) enhancement in wireless communications are disclosed. In one representative embodiment, a method implemented in a wireless transmit/receive unit (WTRU) for wireless communications includes identifying a codebook process from a set of codebook processes based on a first indication, associating a set of bits of hybrid automatic repeat request (HARQ) feedback with the identified codebook process, maintaining the set of bits associated with the identified codebook process based on a condition, receiving a second indication to transmit the set of bits associated with the identified codebook process, and transmitting the set of bits based on the second indication.

    摘要: A wireless transmit receive unit (WTRU) may be configured to monitor physical downlink control channel (PDCCH) candidates of a primary cell (PCell) and a secondary cell (SCell). The WTRU may be configured to determine a time duration for PDCCH candidate budgets for a set of symbols based on a subcarrier spacing associated with the PCell and a subcarrier spacing associated with the SCell. The WTRU may be configured to determine a maximum number of PDCCH candidates to allocate to a search space monitoring occasion of the PCell and the SCell. The maximum number of PDCCH candidates may be based on a per-cell ratio. The WTRU may be configured to allocate PDCCH candidates for the search space monitoring occasion of the PCell and the search space monitoring occasion of the SCell based on the determined maximum number of PDCCH candidates. The WTRU may be configured to decode an allocated PDCCH candidate.

    摘要: Systems methods and devices for transmitting a transport block (TB) over multiple slots. A first grant associated with a hybrid automatic repeat request (HARQ) process in a first set of slots is received. A first subset of the first set of slots is determined to be available, and a second subset of the first set of slots is determined to be unavailable, for uplink transmission. The TB is segmented into a first segment and a second segment in response to the determination. The first segment is transmitted in the first subset of the first set of slots. A second grant associated with the HARQ process is received to transmit the TB in a second set of slots. The second segment of the TB is transmitted in the second set of slots.

    摘要: Systems, methods, and devices for enabling simultaneous transmission of different types of transmission protocols. A device such as a wireless transmit receive unit (WTRU) may receive configuration information and receive a data packet from an upper layer of a protocol stack operating on the WTRU. The WTRU may then determine a transmission type for the data packet at a first time based on the configuration information and a condition. The WTRU may then transmit the data packet using the determined transmission type. The configuration information may include decision criteria associated with determining the transmission type and a set of logical channels that are associated with data properties. The transmission type may be one of a network scheduled mode, WTRU autonomously scheduled mode, LTE, NR, unicast, groupcast, or broadcast.

    摘要: A wireless transmit/receive unit (WTRU) and a method are described herein regarding preservation of positioning integrity associated with wireless systems. Using multiple positioning configurations and/or schemes (e.g., positioning reference signal (PRS) configurations/schemes), e.g., based on a switching pattern, may ensure integrity (e.g., adequate and/or robust integrity), for example, if error events (e.g., low reference signal received power, blockage of PRS from transmission/reception points (TRPs), etc.) have a persistent duration. The WTRU comprises a processor configured to receive a first, a second and a third subset of PRS configuration information, receive configuration information indicating error source information, a first switching pattern, and a positioning uncertainty threshold, perform a first set of measurements using the first switching pattern and the first and second subsets of PRS configuration information, determine a first positioning uncertainty based on the first set of measurements and the error source information, and send an indication indicating measurement information and positioning uncertainty information.
