Introducing a delay in the transmission of a nack for a packet received employing coordinated multi-point transmission

摘要

A communication method in a first apparatus, in which the first apparatus receives data via a direct route from a second apparatus and transmits in response an acknowledgement signal, wherein if the same data has also been transmitted via an indirect route and the data is not properly received via the direct route, the first apparatus introduces an indirect-route delay in transmitting the acknowledgement signal to allow receipt of the data via the indirect route, and otherwise no indirect-route delay is introduced.
