摘要： A wireless device (16) in a wireless communication system (10) is configured to perform measurements on a set of candidate links for supporting a network node (18) in the system (10) to make a decision as to which of the candidate links is to be a target link for a link switch. The wireless device (16) reports (e.g., at the physical layer) measured candidate links one link subset at a time in order of the wireless device's preference for the target link, until the wireless device (16) receives a target indication signal indicating which of the candidate links in the set is to be the target link. Any given link subset reports one or more candidate links which the wireless device (16) has measured for the decision. Responsive to receiving the target indication signal, the wireless device (16) performs the link switch to the indicated target link.

摘要： The present disclosure relates to methods and arrangements for performing wireless device assisted handover form a source access node to a target access node. Performed in a wireless device, a method comprises performing (S31) one or more mobility measurements for corresponding candidate radio links and selecting (S32), from the one or more candidate radio links, an initial target link based on the performed one or more mobility measurements. A first radio link measurement report based on the one or more mobility measurements, identifying the initial target link is transmitted (S33) to a target node providing the initial target link, using a first radio link reporting mechanism. A second radio link measurement report for the one or more candidate radio links and based on the same one or more mobility measurements, is transmitted (S34) to the source access node using a second radio link measurement report different from the first radio link reporting mechanism. Finally, a wireless device connection is initiated (S35) over a handover target link indicated in a handover command from the source access node or over the initial target link, wherein the wireless device connection is initiated over the initial target link based on a reception status for the handover command.

摘要： Methods performed by a wireless device, such as a user equipment, operating in a dormant mode comprise performing a measurement on each of a plurality of resources from a predetermined set of resources or demodulating and decoding information from each of a plurality of resources from a predetermined set of resources, such as a set of beams. The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met. The method further comprises receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.

摘要： The present invention generally relates to wireless communication, more particularly, relates to recovery from beam failure in a wireless access network where beamforming technique is used in communication between network elements. According to one aspect of the present invention, there is provided a method for recovery from beam failure in a wireless access network accessed by a user equipment (UE). The method comprises: at the wireless access network, determining whether the beam failure occurs on the basis of presence of a response from the UE during communicating between the wireless access network and the UE via a first beam; and if it is determined that the beam failure occurs, communicating with the UE via an available beam selected from the first beam and one or more second beams.

摘要： A method for Non-IP traffic communication by UE-to-UE relay is provided. The method is implemented by a network device in a communication network. The method includes receiving a first Direct Communication Request from a source UE. The first Direct Communication Request indicates the establishment of a Non-IP communication link with the source UE and includes a first source UE identifier for the source UE and a first target UE identifier for a target UE. The network device generates a first relay identifier for a relay used in the Non-IP communication link between a source UE and the target UE. The network device maintains a mapping between the first relay identifier, the first source UE identifier, and the first target UE identifier.
