Abstract

Provided is a radio communication technology that can achieve low latency, high reliability, and low jitter characteristics. A transmitter is configured to duplicate a packet and transmit the duplicated packets. The receiver is configured to receive the duplicated packets. The receiver is configured to transfer, to an upper layer in the receiver, a first packet (1401, 1403, 1405, 1408) that is a packet received earlier out of the duplicated packets. A transfer timing that is a timing with which the first packet (1401, 1403, 1405, 1408) is transferred to the upper layer includes at least one of: a reception timing of a second packet (1402, 1404, 1406, 1407) that is a packet received later than the first packet out of the duplicated packets; and a cyclical timing (Cycle time) corresponding to a transmission cycle of the duplicated packets.

Claims11

Dependent claims

A user apparatus in a communication system, the communication system comprising:

a plurality of user apparatuses including the user apparatus, and configured to communicate with each other in a sidelink;
and
a base station configured to wirelessly communicate with each of the user apparatuses,
wherein the user apparatus is configured to:
transmit, to another user apparatus of the plurality of user apparatuses, a request signaling for requesting a setting related to resources for unicast communication in the sidelink, the request signaling including first information on a priority;
receive, from the another user apparatus, second information on the setting related to resources for unicast communication;
perform received power measurement based on threshold set for each resource use;
and
configure the resources for transmission by using the second information and excluding, based on the measurement, a first transmission resource and a retransmission resource from resource candidates for the unicast communication in an autonomous resource selection.
