摘要： A radio communication system of a frequency hopping system, which carries out time division multiplex by TDMA and carries out communications while changing over two or more frequencies with respect to a radio link, wherein radio resources are efficiently utilized by establishing a plurality of radio links. A first communication apparatus periodically transmits control data by a frame cycle and a second communication apparatus which is a communication partner thereof receives the above-described control information during standby and secures synchronization in timing of frames and slots and timing of frequency hopping. Communication signals between both communication apparatuses and control information are overlapped in a slot to establish radio links. Once radio links are established in a plurality of slots other than a slot for transmitting control information, control is performed such that the control information is overlapped in the slots in which a radio link is established.

摘要： In a time division multiplex access (TDMA-TDD) type wireless communication system in which a communication operation is carried out between a first communication apparatus (mother appliance) and a second communication apparatus (child appliance), and since a slot diversity mode is selected while considering power consumption on the side of the second communication apparatus, the wireless communication system performs such a wireless communication having a higher wireless quality. Based upon a power supply remaining energy capacity on the side of the second communication apparatus, and an electromagnetic wave environment when a wireless signal is received, a slot diversity mode is selected. For example, it is so assumed that 1 frame corresponds to 8 slots, a wireless signal is transmitted from the first communication apparatus to the second communication apparatus by employing two, or more slots, whereas a wireless signal is transmitted from the second communication apparatus to the first communication by employing one slot within the remaining 2 to 6 (8-2) pieces of the slots. As a result, since a total number of the wireless transmission slots used in the second communication apparatus is reduced, transmission electric power can be lowered which may occupy a large ratio within the entire power consumption.
