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.

The invention relates to network nodes, a wireless communication device, WCD, and methods therein for handover. The method in the WCD comprises obtaining, from a source network node, information comprising at least part of a WCD Context related to the WCD. The method further comprises connecting to a target network node, and forwarding the obtained information to the target network node, enabling the target network node to derive the WCD Context based on the information.

A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

Embodiments herein relate to a method performed by a first radio network node (12) for enabling a mobility procedure of a wireless device (10) between the first radio network node (12) and a second radio network node (13) in a wireless communication network (1). The first radio network node (12) transmits a first indication to the second radio network node (13), which first indication indicates a position of the wireless device (10). The first radio network node (12) further receives a second indication from the second radio network node (13), which second indication indicates one or more beams used at the second radio network node (13). The first radio network node (12) sends to the wireless device (10) measurement information indicating the one or more beams to perform measurement on and thereby enabling the mobility procedure.

A method performed by a radio-network node for handling a data transmission from the radio-network node to a wireless device in a wireless communication network is provided. The radio-network node transmits (401) data over a number of subframes to the wireless device (10), and a respective control part, associated with the data of each respective subframe, the respective control part comprising a feedback index indicating a transmission time of a feedback indication. The radio-network node receives (402) from the wireless device the feedback indication in the feedback message common for the subframes of the data transmission according to the control parts of the transmitted subframes. The feedback indication indicates feedback for each subframe of the data transmission received and the number of NACKed subframes out of the number of subframes of the data transmission. The radio-network node receives the feedback message and then decides (403) whether or not to retransmit any of the subframes based on the feedback indication therein.
