  • Publication number: 20240196458
    Abstract: Systems, methods, and instrumentalities are described herein regarding Radio Resource Control (RRC) state transitions. The state transitions may be performed with a deactivated Secondary Cell Group (SCG). The WTRU may receive configuration information associated with a transition to a first activity level from a second activity level. The configuration information may indicate one or more conditions associated with determining whether to resume the first activity level with an SCG activated or deactivated. The WTRU may select an SCG activation level to use in association with the first activity level based on the one or more conditions in the configuration information, current WTRU conditions, and current network conditions. The selected SCG activation level may be selected to resume the first activity level with the SCG activated or with the SCG deactivated. The WTRU may indicate, to a base station, the selected SCG activation level.

  • Publication number: 20240196262
    Abstract: A device may transmit data to a first parent node via a first link and to a second parent node via a second link. The device may receive configuration information indicating at least one of: a first buffer threshold associated with a first remaining packet delay budget (PDB), a second buffer threshold associated with a second remaining PDB, or a remaining PDB threshold. The device may receive a packet and may determine a remaining PDB. The device may select a buffer threshold based on the configuration information and the determined remaining PDB. If an amount of data in an uplink (UL) buffer is equal to or above the selected buffer threshold, the device may transmit the packet via a first available link. If the determined remaining PDB is less than the remaining PDB threshold, the device may transmit the packet via both the first link and the second link.

  • Publication number: 20240187939
    Abstract: Systems, methods, and instrumentalities are described herein associated with dual active protocol stack (DAPS) operations (e.g., dual communication operations). DAPS operations may be performed to enable temporary load-balancing. Performing a handover (e.g., DAPS handover) may be expensive (e.g., in terms of resources) and less desirable for load-balancing purposes. Temporary DAPS operations may be performed to achieve temporary load-balancing without performing a handover. A wireless transmit/receive unit (WTRU) in communication with a first network entity may be configured to initiate dual communication operations (e.g., DAPS) towards a second network entity. The WTRU may maintain the dual communication between the first and second network entities, for example, until an indication to release the dual communication is received or until conditions are satisfied. Releasing the dual communication may prevent expensive handovers that may use excess resources.

  • Publication number: 20240147324
    Abstract: 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.

  • Publication number: 20240080697
    Abstract: Systems, methods, and instrumentalities are described herein associated with relay usage (e.g., new radio (NR) relays used as an example herein) where handovers between sidelink (SL) and direct link and/or between sidelinks may be based on consideration of end-to-end radio and/or load conditions. Handover decisions may be determined, for example, based on measurements of direct connections, sidelink connections, and/or backhaul connections. Handover decisions may be optimized, for example, based on measurement reporting behavior. A remote wireless transmit/receive unit (WTRU) (e.g., a WTRU that may be configured to connect to a network, for example, using a relay WTRU) in sidelink relay operation with a relay WTRU may determine measurement reporting behavior (e.g., associated with performed measurements of the direct connections, sideline connections, and/or backhaul connections), for example, while considering the sidelink quality associated with the relay WTRU.

  • Publication number: 20240022944
    Abstract: A wireless transmit receive unit (WTRU) may operate in a dual connectivity (DC) context. While in a RRC_INACTIVE state, the WTRU may receive a paging message from a first cell, which may be associated with a master cell group (MCG). The paging message may indicate that the WTRU is to respond to the paging message on another cell. Also, or alternatively, the paging message may indicate that data for the WTRU is available on an SCG bearer. The WTRU may select a second cell (e.g., a cell other than the first cell) from a secondary cell group (SCG) list, which may include one or more secondary cells. The WTRU may initiate a random access channel procedure with the second cell based on receiving the paging message from the first cell. The WTRU may receive data from the second cell via the SCG bearer while in the RRC_INACTIVE state.

  • Patent number: 11863302
    Abstract: Systems, methods, and instrumentalities (e.g. aspects of entities, interfaces and procedures in a wireless transmit/receive unit (WTRU) and/or network layers L1, L2, l3) are disclosed for low latency medium access control (MAC) protocol data unit (PDU) assembly in wireless systems, such as 5G flexible radio access technology (RAT) (5gFLEX). Latency may be reduced, for example, by WTRU determination of network transmission parameters and signaling prior to a transmission grant. A WTRU may receive a modulation and coding scheme (MCS), resource range, etc. prior to a grant, e.g., for use in future grants. Data blocks may be incrementally created/encoded prior to a grant. Data units may be segmented, assembled and multiplexed, for example, based on data block sizes that allow MAC and radio link control (RLC) processing prior to a grant. Flexible grant sizes may be provided for early generation of transport blocks before a grant.

  • Publication number: 20230354352
    Abstract: Logical channel (LCH) may be multiplexed together based on one or more latency requirements. Mapping of LCH(s) to spectrum operating mode(s) (SOM(s)) may be based on SOM capability and/or LCH requirements. A WTRU may determine mapping based on one or more pre-defined rules. The mapping may be based on one or more requirements for the various type of traffic and/or SOM capabilities. A radio bearer may be mapped to one or more SOMs. The WTRU may be configured with a set of SOMs, for one or more, or each, radio bearer. The WTRU may dynamically determine, for example based on radio conditions, buffer status and/or other parameters, the SOM to use. Incompatible multiplexing of LCH may be reduced and/or avoided, perhaps based on using one or more transport blocks (TBs) mapped to the same physical layer (PHY). Traffic may be prioritized based on one or more latency requirements.
