Abrégé

The invention relates to the allocation of radio resources by a transmitting user equipment to perform a plurality of direct SL transmissions to one or more receiving user equipments. The allocation of radio resources within a SC period is restricted, for the SC period, by a maximum number of SL processes with which a transmitting user equipment is configured. A plurality of SL grants is acquired. Among the acquired SL grants a number of those SL grants is selected that have most recently been acquired before the start of the subsequent SC period. A plurality of SL processes is associated such that each of the plurality of SL process is associated with a different one of the selected number of SL grants. For each of the plurality of the SL processes, the radio resources are allocated. Each of the plurality of SL transmissions comprises at least one SCI transmission and at least one data transmission over the SL interface.

Abrégé

The present disclosure relates to transmitting transport blocks in subframes of a predefined length within a wireless communication system. A downlink control information including a resource grant comprising a predetermined modulation and a predetermined transport block size is received (user equipment is the transmitter) or generated (base station is the transmitter). Then transport block including channel coded data to be transmitted in a subframe with the predetermined modulation and the predetermined transport block size is generated. Sensing is performed in the subframes and based thereon, it is determined whether a partial subframe or a complete subframe is available for transmission of the generated transport block. Finally, the transport block is transmitted with a modified modulation different from the predetermined modulation if the partial rather than complete subframe is available. Correspondingly, at the receiver, the grant is received (user equipment is receiver) or generated (base station is the receiver), the size of the subframe in which the reception is expected is determined and then the transport block is received with a modified modulation if only the partial subframe is available.

Abrégé

The present invention relates to a transmitting terminal for transmitting data to a receiving terminal over a direct link connection. The transmitting terminal comprises a receiving unit that receives from the base station a timing command for adjusting an uplink transmission timing value for data transmissions to the base station. A generating unit generates direct link timing information, based on the uplink transmission timing value, the direct link timing information being usable for generating a direct link transmission timing value for determining the timing of the data transmission over the direct link. A transmitting unit transmits to the receiving terminal the generated direct link timing information, the direct link timing information being usable at the receiving terminal for generating a direct link reception timing value for determining the reception timing of data to be received on the direct link from the transmitting terminal.

The present invention relates to selection of synchronization source among various synchronization sources which include sources determining the synchronization signal from the network such as base stations(network nodes)or user equipments which receive the synchronization signal possibly over other hops from the base station,and which further includes sources which do not determine their synchronization signal from the network. The selection of the synchronization source is performed by choosing the source with the most reliable synchronization signal based on a metric calculated for each of the sources considered.In particular, the metric is based on the type of the source, number of hops between the network and the source and/or received signal quality. After selecting the source, the timing of the device is adapted accordingly.

Abrégé

The present invention relates to a D2D capable a communication method and to a transmitting user equipment, which transmits data to a receiving user equipment over a direct link data channel, uses the services of the eNode B in order to have resources allocated for transmitting said data. To this end the UE sends to the eNB scheduling information using resources of a subframe dedicated for standard uplink communication through the eNode B, rather than using resources on the subframe dedicated to D2D data transmission. In order to allow the eNB to distinguish whether the received scheduling request is for allocating resources for transmitting data over the direct link channel or over the eNB, UE may send along with the scheduling information also identification information associated to the scheduling information.
