摘要

A communication device arranged to communicate data with another device at a given time instant according to either a first communication protocol or a second communication protocol, the communication device being constrained to transmit data according to the first communication protocol during a transmission window of predetermined duration that commences at a predetermined time instant and being arranged to, in dependence on a data communication according to the second communication protocol to be made by the communication device during that transmission window, select a time instant in that same transmission window for commencing a data transmission according to the first communication protocol.

主权项

1. A communication device arranged to communicate data by means of a communication protocol according to which a transmitting device is constrained to transmit data during a transmission window of predetermined duration that commences at a predetermined time value of a local clock of the transmitting device and according to which the communication device should listen for a transmission from the transmitting device during a receive window of predetermined duration that commences before the transmission window at a predetermined time value of a local clock of the communication device, wherein the communication device is arranged to listen for a transmission from the transmitting device during only part of the receive window, the length of the said part being determined in dependence on the precision of the local clock of the communication device,
wherein the communication device is arranged to transmit data during a part of the receive window that lies outside the part of the receive window in which it is listening for a transmission from the transmitting device; and wherein the communication device is capable of communicating data according to two communication protocols, the communication device being arranged to listen for a transmission transmitted by means of a first one of the protocols and being arranged to transmit data according to a second one of the protocols during a part of the receive window that lies outside the part of the receive window in which it is listening for a transmission by the transmitting device.
