摘要： A distribution method and a distribution unit thereof are provided. The distribution unit for the distribution method is coupled to a network entity cluster. In the distribution method, a first packet is received, and a first network entity is selected from a plurality of network entities of the network entity cluster. A target MAC address of the first packet is rewritten to a MAC address of the first network entity, and the first packet to the first network entity is transmitted. With the distribution method, PDU session migration from a busy or failed network entity to an idle one can be within few seconds to avoid service disruption.

摘要： Methods, systems, and devices for wireless communications are described. The described techniques provide for a first user equipment (UE) receiving, from an integrated access and backhaul (IAB) node, an indication that the IAB node supports sidelink communications. The indication may be broadcast by the IAB node or indicated via an established connection, such as a radio resource control (RRC) connection. The first UE may select the IAB node to relay communications between the first UE and a second wireless node based at least in part on the indication that the IAB node supports sidelink communications. The UE may communicate one or more data messages with the second wireless node via the IAB node in accordance the selecting of the IAB node to relay the communications.

摘要： The present disclosure relates to a technique for performing a cell re-selection procedure for a multi-panel user equipment (MPUE) in a wireless communication network that supports network slicing. More specifically, the proposed technique involves considering a spatial separation or, in other words, orthogonality between cells that support the network slice(s) of the mobile MPUE and other neighbouring cells. The mobile MPUE camps/reselects a cell X that supports its network slices only if the spatial separation between the cell X and other neighbouring cells is deemed to be high enough by the MPUE based on parameters received from a serving network node. The parameters may be reported to the MPUE by using a dedicated or broadcast signalling. By so doing, it is possible to provide the slice-based cell re-selection procedure for the mobile MPUE, which may be effectively (in terms of inter-cell interference suppression) used in the intra-frequency scenario.

摘要： Embodiments of the present disclosure are directed to systems and methods for improved cell search of terrestrial base stations. Using a dataset of anticipated coverage areas associated with one or more terrestrial base stations locally stored on a user equipment (UE) and a location of the UE, the UE can determine if it is within a predetermined threshold distance of the one or more anticipated coverage areas. If so, the UE may perform cell search for the one or more terrestrial base stations; if not, the UE may not perform cell search or perform cell search less often to prevent unnecessary battery depletion.

摘要： A wireless transceiver device includes a communication module and a processor. The communication module is used for receiving and transmitting radio frequency signals. The processor is coupled to the communication module and configured to perform the following operations in accordance with a predetermined condition: determining candidate transmission modes according to a current transmission mode of the communication module, in which a packet error rate of the communication module is less than an error rate threshold in each candidate transmission mode; and determining one of the candidate transmission modes with a least power consumption value as a subsequent transmission mode of the communication module.

摘要： This document describes techniques and apparatuses for handling radio resource control (RRC) cell group configuration. In implementations, a base station (120) receives a first radio resource control message that requests a connection procedure between a user equipment (110) and the base station (e.g., 325, 425, 1325), such as a radio resource control resume request or a radio resource setup request. In response to receiving the first radio resource control message, the base station (120) generates a second radio resource control message that includes a cell-group-configuration information element that excludes a reconfiguration-with-sync information element (e.g., 330, 430, 1330). The base station (120) then transmits the second radio resource control message to the user equipment (110) (e.g., 335, 435, 1345). Afterward, the base station (120) receives, from the user equipment (110), a third radio resource control message that indicates the connection procedure is complete (e.g., 340, 440, 1350).

摘要： Mobile user devices, seeing a base station, can usually detect multiple base stations and access points capable of supporting communications in 5G or 6G. However, some of these may be crowded or distant, while others may be close enough to provide excellent reception. To assist the mobile user device in selecting an optimal base station for signal quality, the user device can include a network database that lists the locations and frequencies (and other data) about available base stations and access points. The user device can then use an artificial intelligence (AI) model, or an algorithm derived from AI, to select the base station or access point likely to provide the best signal quality while in transit. This would be much faster and simpler than the current alternative, of blindly searching through all the detectable base station sequentially.

摘要： In mobility scenarios, a user equipment (UE) may enter an airplane mod in which the UE has limited or no connectivity to a network. Cell selection latency after terminating the airplane mode may result in a delay in providing network or communication services. Some aspects described herein enable a reduction in latency associated with cell selection after operation in a mobility scenario. For example, a UE may determine that the UE is operating in a mobility scenario, and perform a receive-only cell selection procedure. Additionally, or alternatively, the UE may predict a destination associated with the mobility scenario and may identify a band list for performing a cell selection procedure. In this way, when the UE exits the mobility scenario, the UE reduces a time to successfully complete cell selection.
