  • Publication number: 20240138001
    Abstract: A first wireless communication device (401, 404), WCD, transmits a first indication to a second WCD (401, 404) or receives a first indication from the second WCD. The first indication indicates a first time period (501) during which the first WCD is expected to monitor for receipt of a transmission. The first WCD monitors for receipt of a transmission during the first time period. The first WCD is not expected to monitor for receipt of a transmission during a second time period (502) before the first time period begins. The first WCD performs the transmission or receipt of the first indication after a link has been established between the first WCD and the second WCD for relaying of information to and/or from a network via one or more sidelink transmissions between the first WCD and the second WCD.

  • Publication number: 20240129873
    Abstract: Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.

  • Patent number: 11963103
    Abstract: Methods and apparatuses for paging are disclosed. According to an embodiment, a paging related entity obtains first information about a probability at which each of at least one terminal device is paged at a paging occasion (PO). The paging related entity obtains second information about a first power consumption and a second power consumption spent by each of the at least one terminal device for detecting a wake up signal (WUS) and a paging message respectively. The paging related entity determines, for multiple applicable WUS to PO mapping parameters, corresponding power consumptions spent by the at least one terminal device in a paging time window (PTW), based on the first and second information. The paging related entity determines, as a target WUS to PO mapping parameter to be applied to the at least one terminal device, one of the multiple applicable WUS to PO mapping parameters corresponding to a lowest power consumption in a PTW.

  • Publication number: 20240080927
    Abstract: A wireless communication device, WCD, receives a message from a network node in a communication network. The message indicates that the WCD is to save a user equipment, UE, context of the WCD. In response to receiving the message, the WCD saves the UE context. The message also indicates that the WCD is to transition from a connected state to an inactive state when a first condition is satisfied, and/or remain in an inactive state when a second condition is satisfied. The first and/or second condition may for example include that the WCD experiences a loss of connection or loss of coverage, or that the WCD experiences a radio link failure.
