    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: A method for a Wireless Transmit/Receive Unit (WTRU). The method including receiving from a network configuration information indicating multiple frequency layers for positioning reference signals; and at least one activated frequency layer from among the multiple frequency layers. The frequency layers may be associated with one or more carriers for data transmission, wherein the carrier is co-located with its associated frequency layer for positioning; and bandwidth parts (BWPs) within carriers for data transmission. The WTRU may receive from the network activation/deactivation information indicating activation/deactivation of any of a secondary cell (SCell) and a BWP. The WTRU may transmit information indicating, for example, a set of frequency layers used for positioning, wherein the set of frequency layers is enabled according to any of an accuracy requirement, a latency, a measured RSRP of one frequency layer, and a measured CSI-RS corresponding to BWPs being a threshold.

    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: Methods and apparatuses are described herein for selective one-shot hybrid automatic repeat request (HARQ) feedback by priority level. For example, a wireless transmit/receive unit (WTRU) may determine a priority associated with each transport block (TB). The each TB may correspond to respective HARQ processes associated with downlink transmissions from a base station (BS). The WTRU may receive, from the BS, a request for the one-shot HARQ feedback with an indication of a priority selected for the one-shot HARQ feedback. The WTRU may generate a HARQ codebook for transmission of the one-shot feedback. The HARQ codebook may comprise one or more information bits corresponding to one or more TBs determined based on the indicated priority. The WTRU may determine, based on a number of the one or more information bits, a transmission power and transmit, at the transmission power, the one-shot feedback comprising the generated HARQ codebook.

    摘要: Systems, methods, and instrumentalities are disclosed that may be associated with HARQ-ACK codebook adaptations. A WTRU) may be configured with multiple physical uplink channels, e.g., physical uplink control channels (PUCCHs), in a slot. Each physical uplink channel may have a respective HARQ-ACK codebook. In examples, the WTRU may determine that a first physical uplink channel and a second physical uplink channel overlap in a slot. In such a case, the WTRU may determine that a first HARQ-ACK codebook associated with the first physical uplink channel has a higher priority than a second HARQ-ACK codebook associated with the second physical uplink channel. The WTRU may transmit the first HARQ-ACK codebook on the first physical uplink channel in the slot. The WTRU may send part of the second HARQ-ACK codebook in the slot and part of the second HARQ-ACK codebook in a subsequent slot (e.g., a next slot, a future slot, etc.).
