There are provided methods for predicting timing advance (TA) with respect to a base station. According to some embodiments, the method includes determining, by a user equipment (UE), a set of TAs, each TA corresponding to a particular distance from the base station and measuring, by the UE, a set of instances of a power metric, each instance of the power metric associated with a respective distance from the base station. The method further includes determining, by the UE, a set of differences between each of the instances of the power metric and determining, by the UE, a new TA at least in part using the set of TAs and the set of differences.

Method and apparatus for timing advance prediction

There is provided a method and user equipment (UE) for supporting device to device (D2D) communication, for example side link communication, of wireless devices. At least one of the source UE or the destination UE is out of synchronization. Side link (SL) communication information (e.g. SL sync signal, SL timing request message, SL-data, special sync signal) may be blindly and repeatedly transmitted until the source UE receives a response from the destination UE.

Method and apparatus for supporting device to device communication for wireless devices

There is provided methods and associated base station and user equipment, for facilitating transmissions in a wireless communication system. The mapping between an index and its corresponding HARQ ID or HARQ ID & NDI pair can be done using one or more equations relating the two entities. The equations can be defined in two configurations, one for encoding HARQ ID or HARQ ID & NDI pair and a second for decoding the encoded HARQ ID or HARQ ID & NDI pair to determine the HARQ ID or HARQ ID and NDI.
