  • Patent number: 12763900
    Abstract: Methods of compact Tracking Reference Signal (TRS) configuration for New Radio (NR) User Equipment (UE) are provided. The Channel State Information Reference Signal (CSI-RS) configuration framework through which the TRS is traditionally configured in connected mode is quite hefty in terms of number of possibilities and Information Elements (IEs) included in its structures. It entails IEs that can be used for configuration of multiple sets (up to 16) of both Zero Power (ZP) and Non-Zero Power (NZP) CSI-RSs. Each of these sets can itself include configuration of up to 64 resources. In order to be able to provide TRS configuration and availability information to the UEs in Radio Resource Control (RRC) Idle/Inactive states, a compact TRS mechanism is disclosed through which the network can configure the UE with specific TRSs.

  • Publication number: 20260304290
    Abstract: A method implemented in a UE includes receiving a first signal or a first sequence from a cell, and determining from a bit, a flag, or a signature in the first signal or the first sequence whether the UE is indicated as being barred from accessing the cell. Responsive to when a result of the determination is that the UE is not indicated as being barred from accessing the cell, the method determines from a second signal or a second sequence received from the cell whether the UE is further indicated as being barred from accessing the cell. The second signal or the second sequence includes information indicating whether the cell is barred or not barred for all NES capable UEs. Other related methods implemented by network nodes, NES-capable network nodes, and non-NES-capable network nodes are disclosed.

  • Publication number: 20260281778
    Abstract: Various embodiments disclosed herein provide for a method for configuring a User Equipment (UE) to store and report information related to performance degradation associated with Network Energy Savings (NES) features that are configured or active in the cell in which the UE is connected at the time of the performance degradation. The UE can receive a configuration to store and report the information, and then the UE can determine when an NES feature is activated or configured in the cell, and then when performance degradation occurs (e.g., radio link failure or handover failure) the UE can store the information and then report the information to a network node.

  • Patent number: 12726899
    Abstract: The efficient usage of receivers for paging-early-indication (PEI) reception in a user equipment (UE) is described. The UE determines to use a wake-up receiver (WUR) as the primary receiver for monitoring PEO when waking up in Discontinuous Reception (DRX). The WUR consumes less power than a main receiver of the UE. The UE detects, at the WUR, a PEI and activates the main receiver of the UE for monitoring a paging occasion (PO). Responsive to determining that a condition for using the WUR as the primary receiver for monitoring PEI when waking up in DRX is not satisfied, the UE switches to using the main receiver as the primary receiver for monitoring PEI when waking up in DRX and not using the WUR for monitoring PEI.

The at least one paging condition is associated with a current paging configuration for said at least one UE and comprises at least one of a false paging rate, latency, PDCCH load, and PDCCH and PDSCH imbalance. The method further comprises determining whether the obtained information regarding the at least one paging condition exceeds a respective associated threshold; and updating, based on the determination, the current paging configuration into an updated paging configuration for said at least one UE.

  • Publication number: 20260239396
    Abstract: A method performed by a first UE for handling a Multicast Broadcast Service (MBS) session in a wireless communications network is provided. The first UE receives (503) a second indication as transmitted by a network node (130).
