  • Publication number: 20240381429
    Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information that indicates associated random access channel occasions (ROs). for example, a first RO and a second RO. The WTRU may determine a feature combination associated with the WTRU. The WTRU may determine a set of preambles based on the feature combination associated with the WTRU. The set of preambles may include multiple subsets of preambles, for example, a first subset of preambles associated with the first RO of the associated ROs and a second subset of preambles associated with the second RO of the associated ROs. The WTRU may transmit a first preamble of the first subset of preambles on the first RO of the plurality of associated ROs and a second preamble of the second subset of preambles on the second RO of the plurality of associated ROs.

  • Patent number: 12143949
    Abstract: An access node may provide synchronization information to a UE. The access node may further provide one or more information blocks, which may include basic network configuration information. Based on the synchronization information and/or the information block(s), the UE may transmit a message to the access node that includes a random access preamble, an identifier of the UE, and/or a buffer status report. Based on the message from the UE, the access node may determine that the UE should remain active and, therefore, may transmit a response to the first message to the UE indicating that the UE should remain active. Thereafter, the UE may receive a connection setup or connection reconfiguration message. The connection setup or reconfiguration message may be received from the same or different access node from which the UE received the synchronization information and/or the one or more information blocks.

  • Publication number: 20240284456
    Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products related to a Wireless Transmit-Receive Unit (WTRU) operating in a network, for supporting paging using an Ultra-Low Power (ULP) receiver, are disclosed. A WTRU may receive a ULP-specific configuration, and may activate the ULP receiver, and inactivate the Uu receiver, when support of ULP paging operation, by the network, is determined. The ULP receiver may detect a Low-Power Wake-Up Signal (LP-WUS) and may activate the Uu receiver and perform PDCCH monitoring. Under condition that the WTRU detects, in the channel monitoring, its identifier in a paging message received via the Uu receiver, the WTRU initiates a connection establishment or a connection resume procedure.

  • Publication number: 20240276445
    Abstract: A wireless transmit/receive unit (WTRU) may be configured to receive configuration information from a network indicating first reporting behavior and second reporting behavior to be applied when reporting measurements associated with a beam. The configuration information may indicate a condition associated with a height of the WTRU, a speed of the WTRU, and/or a location of the WTRU. The WTRU may be configured to determine whether the condition associated with the height of the WTRU, the speed of the WTRU, and/or the location of the WTRU has been satisfied. The WTRU may be configured to send a report indicating the beam measurements of the candidate set of cells using the first reporting behavior or the second reporting behavior based on whether the condition associated with the height of the WTRU, the speed of the WTRU, and/or the location of the WTRU has been satisfied.

  • Patent number: 12047929
    Abstract: Aspects of the present disclosure describe managing beams in wireless communications. A beam management event configuration indicating a type of at least one beam to measure in determining occurrence of a trigger condition for a beam management event can be received. A parameter of a signal received from one or more nodes can be measured, where the signal corresponds to the type of the at least one beam. The occurrence of the trigger condition for the beam management event can be determined based on the parameter of the signal. An indication of the occurrence of the trigger condition can be reported to the one or more nodes or a different node.

  • Publication number: 20240236739
    Abstract: Systems, methods, and instrumentalities are described herein for idle mode mobility in an ultra-low power (ULP) system. Idle mode mobility in a ULP system may support energy efficient downlink signaling. An association may be identified between a Uu cell and a ULP cell. Switching between Uu cells may limit power savings gains from ULP receivers. Enabling switching between ULP cells without switching between Uu cells may help maintain the power savings gains from ULP receivers. A wireless transmit/receive unit may be configured to perform ULP cell reselection, for example, without triggering Uu cell reselection (e.g., to maintain power savings gains).

The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.

  • Patent number: 11751113
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

  • Patent number: 11696331
    Abstract: Logical channel prioritization and mapping to different numerologies is disclosed for 5G networks having multiple network slices operable for communication via logical channels associated with different numerologies. For user equipments (UEs) configured to handle multiple numerologies, different rules for mapping logical channels associated with different numerologies may be defined for data and non-data channels. Thus, when new data arrives at a UE for communication via a logical channel associated with a different numerology, the UE checks whether the mapping rules would allow multiplexing of the new numerology data onto an existing data channel. If no data channel has already been allocated or if an allocated data channel may not include data from the new numerology, then a mapping is followed for specifically requesting resources for communication of the new numerology data. The new mapping may trigger scheduling request or random access procedures specifically associated with the new numerology.
