Abstract: The invention provides a mobile communication device having a first wireless communication module with a strong driving circuit, and a second wireless communication module with a weak driving circuit. The first wireless communication module is coupled to the second wireless communication module via only one wire. The first wireless communication module sends a first traffic pattern of a first wireless transceiving to the second wireless communication module via the wire, and receives a second traffic of a second wireless transceiving from the second wireless communication module via the wire. The second traffic pattern indicates whether the second wireless communication module decides to use a remaining period of time, in which the first wireless communication module is not required to perform wireless transceiving, for the second wireless transceiving.

Abstract: A wireless communication device has a first wireless communication module coupled to a second wireless communication module via only one wire. The first wireless communication module is configured to performing a first wireless transceiving and to send a first request to the second wireless communication module indicating a remaining period of time to perform a second wireless transceiving, during which the first wireless communication module is not required to perform wireless transceiving. The second wireless communication module is configured to perform a second wireless transceiving, the second wireless communication module further configured to send a first response to the first request by indicating acceptance of the request if a status of the second wireless communication module is in an active mode, else by indicating that the first request is not accepted if the status of the second wireless communication module is in a sleep mode.

Abstract: A system for the coexistence between a plurality of wireless communications modules sharing single antenna is provided. A wireless communications chipset includes a first wireless communications module configured to transmit or receive first wireless communications signals, and a second wireless communications module configured to transmit or receive second wireless communications signals. A path selection circuit is configured to connect the first wireless communications module to the antenna via a first transceiving path or a second transceiving path for transmitting and receiving the first wireless signals according to transceiving statuses of the first wireless signals and the second wireless signals.

Abstract: A wireless communications includes a first wireless communications and a second wireless communications. The first wireless communications module transmits or receives a first wireless signal in a first frequency band selected from a first frequency range. The second wireless communications module transmits or receives a second wireless signal in a second frequency band selected from a second frequency range, and adjusts a transmission power of the second wireless signal in response to that a frequency offset between the first frequency band and the second frequency band falls within a predetermined range. The first wireless communications module is further configured to determine an in-band range in the overlapping part of the first and second frequency ranges, and a transmission power of the second wireless signal is adjusted in response to a frequency offset between the first frequency band and the second frequency band.
