Abstract

A user equipment for a mobile communication network is provided. The mobile communication network has a radio access network including a plurality of cells and being configured to serve the user equipment within a cell. To receive a data packet from the radio access network, the user equipment is configured to receive a plurality of different versions of the data packet transmitted by the radio access network to the user equipment in parallel via different physical resources. To provide a data packet to the radio access network, the user equipment is configured to provide a plurality of different versions of the data packet and to transmit the plurality of different versions of the data packet to the radio access network in parallel via different physical resources.

Claims19

Dependent claims

A user equipment (UE) for a mobile communication network, the mobile communication network comprising a radio access network (RAN) comprising a plurality of cells and being configured to serve the user equipment within a cell, the user equipment comprising:

one or more antennas for receiving from and/or providing to the radio access network a data packet, and
a signal processor,
wherein, to receive the data packet from the radio access network, the user equipment is configured to receive a plurality of different versions of the data packet transmitted by the radio access network to the user equipment in parallel via different physical resources, and/or
wherein, to provide the data packet to the radio access network, the user equipment is configured to provide a plurality of different versions of the data packet and to transmit the plurality of different versions of the data packet to the radio access network in parallel via different physical resources,
wherein the plurality of different versions of the data packet are acquired by performing a packet redundancy/duplication, and
wherein the user equipment (UE) is configured to send or receive for the plurality of different versions of the data packet
a single ACK/NACK message, or
only a NACK message
wherein the single ACK/NACK message includes information about which physical resource provided an ACK and which physical resource provided a NACK.
