摘要:
A system for managing the operation of a plurality of radio modems integrated within the same wireless communication device. In at least one embodiment of the present invention, a control strategy may be employed to manage the operation of a plurality of radio modems and/or wireless mediums. A signal normally used to reactivate or “wake-up” system components in an inactive or sleep mode may also be employed to convey timing and/or control information to the system components of the wireless communication device.

A method and system for establishing a wireless communications link determines, through a first short-range communications link of a first type, whether a remote device is capable of supporting a short-range communications link of a second type. If so, information is exchanged with the remote device across the first communications link to establish a second short-range communications link of the second type. Once established, communications with the remote device across the second short-range communications link may commence. The first communications link may be a Bluetooth link and the second communications link may be an ultra wideband (UWB) link.
摘要:
A system for managing the simultaneous operation of a plurality of radio modems in a single wireless communication device (WCD). The multiradio control may be integrated into the WCD as a subsystem responsible for scheduling wireless communications by temporarily enabling or disabling the plurality of radio modems within the device. The multiradio control system may comprise a multiradio controller (MRC) and a plurality dedicated radio interfaces. The radio interfaces are dedicated to quickly conveying delay sensitive information to and from the radio modems. The modems may further include control features that take information from the MRC as an input in determining the priority of messages to be sent out to a receiving device.

The invention relates to a method for broadband communication. The method includes transmitting a sequence of pulses or impulses at a pulse repetition frequency from a first communication device to another device via a wireless link. The method further includes adjusting the pulse repetition frequency based on channel delay spread measurements performed by said another device.
摘要:
A condition of a short-range wireless communications link is determined. From this determination, one or more frequency hopping patterns are selected for the short-range wireless communications link. The selected pattern(s) may employ different frequencies for adjacent time slots when the determined condition indicates the short-range wireless communications link is susceptible to inter-symbol interference (ISI). Conversely, the selected patterns may employ the same frequencies for two or more adjacent time slots when the determined condition indicates the short-range wireless communications link is not susceptible to ISI.

A method, apparatus and computer program product are provided for facilitating device discovery so as to consume less power with reduced channel occupancy. In regards to a method implemented by a master device, a scan for an advertisement is caused to be performed and an advertisement packet is received during the scan that defines a time period in which the source device of the advertisement packet will be performing a page scan. The method also determines the time period in which the source device of the advertisement packet will be performing the page scan. The method also causes a page to be issued during the time period in which the source device of the advertisement packet will be performing the page scan, and then receives a page response in response to the page. Corresponding apparatus and computer program products as employed by both master and slave devices are also provided.
摘要:
A communication device including a receiver for receiving information via a first radio protocol directly from a first communication device concerning at least a second radio protocol; and a controller for controlling communication of the communication device in dependence upon the received information.

The invention relates to a method and to a modulator for modulating signals. The signals are to be transmitted by a device in packets via an air interface. Each packet is supposed to comprise at least one entity of at least two different entities, which different entities are employed for transmitting signals representing different kinds of information. In order to enable a higher data rate, signals that are to be transmitted in at least one of said different entities are modulated with a first set of values of at least one modulation parameter of a selected modulation scheme. Further, signals that are to be transmitted in at least one other of said different entities are modulated with a second set of values of said at least one modulation parameter, said second set of values comprising less values than said first set of values.
摘要:
A system and method are disclosed for reducing interference in simultaneous wireless LAN (WLAN) and wireless personal area network (PAN) signal handling in mobile wireless terminals having both a WLAN and a PAN interface. The wireless terminal includes a first transceiver operating in the PAN network in a communications band and a first communications protocol transmitting first data units. The wireless terminal also includes a second transceiver operating in the WLAN network in substantially the same communications band and a second communications protocol transmitting second data units. The wireless terminal further includes a controller coupled to the first and second transceivers, assigning a higher transmission priority to the second data units than to the first data units when transmission of the second data units overlaps a first occurring transmission of the first data units, to abort transmission of the first occurring data unit. The controller assigns a higher transmission priority to the aborted first data unit than to the second data units when transmission of the second data units overlaps the retransmission of the aborted first data unit, to transmit the aborted first data unit.
