Method for the transmission of information and apparatus employing the method

在通信链路上传递信息的方法和装置，包括以第一电平发射信息、监视发射信息的正确接收，如果没有出现正确接收，用比原来传输所用的更高的第二电平发射更多的信息。更多的信息使原来发射的信息内容能够建立，而且在一个实施例中构成了原来发射信息的重传。通过以较大电平重发，正确接收的概率增加了，特别是在通信链路是无线的情况下更是如此。使用本发明的发射机可以实现功耗的降低，因为用于原始传输的发送电平可以比没有从本发明受益的发射机所用的更低。 A method and apparatus for transferring information over a communications link includes transmitting information at a first power level, monitoring for correct reception of the transmitted information and transmitting further information at a second-, greater power level than that used for the original transmission if correct reception did not occur. The further information allows the content of the originally transmitted information to be established and in one embodiment constitutes a retransmission of the originally transmitted information. By retransmitting at a greater power level the probability of correct reception is enhanced, especially when the communications link is wireless. A transmitter employing the present invention may offer reduced power consumption since the transmission power level used for the original transmission may be lower than that used by a transmitter not benefiting from the present invention.
