Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of signalling enabling Timing Advance (TA) exchange between User Equipment (UE) and Radio Access Network (RAN). The method comprises receiving, at a first device, a TA margin from a second device; transmitting, to the second device, information associated with a reference location of the first device at a first time point; determining a reference TA of the first device at least based on the reference location of the first device; determining an actual TA of the first device at least based on an actual location of the first device at a second time point; and determining, based on a comparison of a TA margin with a difference between the reference TA and the actual TA, whether to transmit an updated reference location of the first device to the second device. In this way, the control for uplink overhead from TA/location updates and probability of impacting downlink scheduling become flexible. Furthermore, the downlink delay can be optimised and meanwhile overhead in case of very few small packets transmitted can be minimized. As a result, the network can optimize its own performance and the battery savings of the users.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for handling of measurements relaxation and other activity skipping. The user equipment (UE) may be allowed to relax its various measurements if one or more radio link quality-based relaxation conditions are satisfied and based on whether the UE is also allowed, at the same time, to skip other activities. Based on certain embodiments, the UE may perform the measurements, if another activity has to be performed since relaxation may not provide any power saving benefit under such situation.

Abstract: A base station serving UE(s) receives validity time information for cell(s) formed by other base station(s). The validity time information indicates at least a time period when corresponding cells are available for use by the UE(s). The base station determines action(s) to perform for the UE(s) based on the validity time information. A UE receives, from a base station, validity time for cell(s) formed by other base station(s). The UE performs action(s) based on the validity time of the cell(s).

Abstract: A terminal device, initially, maintains, in at least one memory, a configuration for a Radio Resource Control, RRC, inactive state. The configuration includes information on a radio access network notification area, RNA. The terminal device, then, acquires information on an expected latency of incoming RRC messages within the RNA. In response to triggering a RRC connection resume procedure, the terminal device performs the following: First, the terminal device transmits a RRC connection resume request to a target access node and starts a timer defined based on the expected latency. In response to the timer expiring, the terminal device initiates monitoring of incoming RRC messages. In response to receiving a RRC connection resume message, the terminal device initiates the RRC connected state.

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: Example embodiments of the present disclosure relate to a solution for handling positioning measurement. In this solution, a first apparatus may determine a relationship between a completion time of a positioning measurement and an availability time of a serving cell of the first apparatus, or a first time length of a duration for performing the positioning measurement and a second time length of a validity duration of an uplink synchronization parameter in the serving cell. Then based on the determined relationship, the mobility activities may be processed properly.
