TELECOMMUNICATIONS APPARATUS AND METHODS FOR HALF-DUPLEX AND FULL-DUPLEX

摘要

A telecommunications system including plural base stations and plural terminal devices to communicate over a radio interface having a radio frame structure including radio subframes each including plural symbols. At least one symbol in each radio subframe is used to support a physical shared channel and at least one symbol in each radio subframe is used to support a physical control channel associated with the physical shared channel. A symbol at the end of each radio subframe is used to support the physical shared channel for communication links between a base station and a terminal device operating in a full-duplex mode, but the corresponding symbol is used to support a separate physical channel, for example an additional low-rate channel, for communication links operating in a half-duplex mode. Transmission resources that would normally be idle in a half-duplex system as compared to a full-duplex system can be re-used for another channel.

1. A telecommunications system comprising a plurality of base stations and a plurality of terminal devices arranged to communicate over a radio interface having a radio frame structure comprising radio subframes, wherein each radio subframe comprises a plurality of symbols, and at least one symbol in each radio subframe is used to support a physical shared channel and at least one symbol in each radio subframe is used to support a physical control channel associated with the physical shared channel, and wherein a symbol at the beginning or end of each radio subframe is used for a communication link between a base station and a terminal device operating in a full-duplex mode to support the physical shared channel and is used for a communication link between a base station and a terminal device operating in a half-duplex mode to support a different additional physical channel.
