Abstract: Example embodiments of the present disclosure relate to a solution for configuring a retransmission in communications. In an aspect, a first device transmits, to a second device, a first indication of a plurality of candidate retransmission configurations. Each of the plurality of candidate retransmission configurations includes a transmission feedback configuration and/or a data retransmission configuration. The first device selects a target retransmission configuration from the plurality of candidate retransmission configurations. The first device transmits, to the second device, a second indication of the target retransmission configuration. The first device communicates with the second device using the target retransmission configuration. The example embodiments of the present disclosure provide a dynamical multi-level indication for a retransmission scheme.

Abstract: Various communication systems may benefit from improved HARQ. For example, it may be helpful to improve HARQ in non-terrestrial networks. A method may include receiving at a user equipment a configuration from a network entity. The configuration may include a hybrid automatic repeat request virtual process number. The method may also include receiving at the user equipment a downlink control information from the network entity. The downlink control information may include a hybrid automatic repeat request virtual process identification. In addition, the method may include receiving at the user equipment another downlink control information. The another downlink control information may include the hybrid automatic repeat request virtual process identification. Further, the method may include determining at the user equipment a difference between a timing of a transmission indicated by the downlink control information and another timing of another transmission indicated by the another downlink control information.

Abstract: The position detection of user equipment within a network, and the corresponding methods performed at the network node, user equipment and location server are disclosed, along with these entities and a computer program. The method performed at the network node comprises within a position reference signal time period, broadcasting: a first position reference signal within a first frequency band and during a first time period; and at least one further position reference signal within at least one further frequency band and during at least one subsequent time period, said at least one further frequency band being different to said first frequency band.

Abstract: Devices, methods and computer programs for timing advance variation compensation in wireless communications are disclosed Timing advance variation for a client device communicating with a network node device at least partially via an air/space born vehicle communication connection is determined based on measurements on uplink signaling from the client device. A timing advance compensation function curve from a set of predetermined timing advance compensation function curves is selected, such that the selected timing advance compensation function curve corresponds with the determined timing advance variation. An indication of the selected timing advance compensation function curve is signaled to the client device.

Abstract: Methods and apparatus for transmitting positioning measurement report are provided. The method includes a step of receiving a location information request from a serving base station or from a location server, a step of determining timing for transmitting a positioning measurement report, a step of generating a report assisted message based on the determined timing for transmitting the positioning measurement report, and a step of transmitting the report assisted message to the serving base station. The key idea of this disclosure is requesting UL resources for positioning measurement report in advance by transmitting a report assisted message. Consequently, the UE can transmit the positioning measurement report just after the measurement data being generated. The disclosure can minimize the delay from positioning measurement data generation to the positioning measurement report.
