20230088376 · 2023-03-23 ·

Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

PACKET COMMUNICATION SYSTEM, AND ITS TRANSMITTING APPARATUS, RECEIVING APPARATUS, AND PROGRAM

According to one aspect of the disclosure, in a communication apparatus at a transmission end, a packet train that is input is grouped to generate a duplicate packet for each packet group. For each packet group, encoded packets are generated using some packets in a group of duplication source packets and other packets in a group of duplicate packets that do not correspond to the some packets in the group of duplication source packets, and above-described other packets in the duplication source, some packets in the group of duplicate packets that are not used to generate the encoded packets, and the above-described encoded packets are transmitted. On the other hand, in a second communication apparatus at a reception end, the some packets in the group of duplication source packets and the other packets in the group of duplicate packets are decoded based on, among the received packets described above, either the other packets in the group of duplication source packets or the above-described some packets in the group of duplicate packets, and the encoded packets, and when some packets of the packet group are lost in a network, the above-described lost packets are restored by the above-described decoded packets.
