摘要： Systems and methods for adapting a timer(s) for a satellite-based radio access network are disclosed. Embodiments of a method performed by a wireless device and corresponding embodiments of a wireless device are disclosed. In some embodiments, a method performed by a wireless device comprises obtaining a value to be used to offset, extend, and/or scale one or more timers related to the satellite-based radio access network relative to values for non-satellite-based radio access networks. The method further comprises utilizing the value to offset a start of one or more timers, extend one or more timers, and/or scale one or more timers and performing one or more actions based on the one or more offset timers, the one or more extended timers, and/or the one or more scaled timers. Embodiments of a method performed by a base station and corresponding embodiments of a base station are also disclosed.

摘要： A system, method and non-transitory computer readable media for facilitating reduced signaling load with respect to UE location reporting in a non-terrestrial network (NTN) environment (100) interoperable with one or more terrestrial cellular communications networks. In one embodiment of an index-based location reporting scheme, a UE (105, 1200) may receive (402) a list of reference locations from a network node (1000, 1100), each identified with an index. Responsive to receiving the list of reference locations, the UE (105, 1200) may report to the network node (1000, 1100) an index or a subset of indices of one or more reference locations that match a specific reporting criterion. In an example implementation, reporting of index-based location information by the UE (105, 1200) may be configurably triggered, e.g., periodically or in response to the occurrence of a particular event, condition, etc.

摘要： A network node of a wireless communication network provides information to a User Equipment (UE) that allows the UE to adapt it radio measurements with respect to the network, to account for “link changes.” Link changes are service-link and/or feeder-link changes arising from motion by the satellite(s) included in the Radio Access Network (RAN) portion of the network. The UE uses the provided information to adapt its radio measurements in conjunction with the link changes. Among the several advantages of accounting for satellite link changes in the manner contemplated are any one or more of reduced signaling going between the UE and the network, reduced battery consumption at the UE, mitigation of the effects of the link changes on the radio measurements, avoidance of spurious measurements, and an effective “automation” of the timed changeover by the UE to new measurement configurations, coincident with the occurrence of link changes.

摘要： A method performed by a network node (160) includes serving a cell area by a first physical network node for a first time duration. The first physical network node uses an identifier of a logical network node. For a second time duration, the cell area is served by a second physical network node. The second physical network node uses the identifier of the logical network node. The first physical network node serves the cell area with a first frequency band and the second physical network node serves the cell area with a second frequency band.

摘要： A method by a wireless device includes determining whether one or more conditions for triggering measurements have occurred and performing the one or more measurements based on the occurrence of the one or more conditions. The one or more conditions for triggering measurements is based on at least one of: a timing advance value in a source cell; a distance between the wireless device and a satellite node serving a source cell or a candidate target cell; an expected time for the wireless device to be served in the source cell and/or in the candidate target cell; elevation angle of the satellite node serving the source cell and/or the candidate target cell; a point in time configured by a network node is reached; detection of an identifier associated with a specific cell; and a speed or velocity of the wireless device.

摘要： Embodiments described herein provide methods and apparatus for performing a random access procedure to access a wireless communications network. A method in a wireless device comprises responsive to transmitting a first random access preamble to a base station using first random access resources in an uplink, UL, bandwidth part, BWP, of a carrier: selecting, based on an association, a first downlink, DL, BWP of the carrier, wherein the association maps a plurality of DL BWPs of the carrier to different values of a parameter related to physical random access configurations and/or to different UL BWPs of the carrier; and monitoring the first DL BWP in order to receive a random access response from the base station.

摘要： Methods and arrangements for managing a retransmission on a Random Access CHannel, “RACH”, in a wireless communication network (100). A device (600; 120) performs (404; 502) the retransmission on the RACH, wherein the retransmission is based on a coverage class associated with the device (600; 120). Basing the retransmission on the coverage class e.g. enables reduction of retransmission collisions when the wireless communication network (100) operates as in Extended Coverage GSM, “EC-GSM”.
