Abstract:

Embodiments of a multi-radio wireless communication device having a Worldwide Interoperability for Microwave Access (WiMax) radio module and a Bluetooth (BT) radio module and methods for communicating are generally described herein. Other embodiments may be described and claimed. In some embodiments, a WiMax active signal is asserted by a coexist controller of the WiMax radio module during receipt of a downlink subframe, and the BT radio module aligns a BT slot boundary of either master-to-slave or slave-to-master slot based on timing information conveyed by the WiMax active signal. The WiMax active signal may be de-asserted by the coexist controller during transmission of an uplink subframe by the WiMax radio module.

International Classification:

H04Q 7/24

US Classification:

370338, 370315, 4555501

Abstract:

Methods and arrangements for link rate adaptation in multi-radio co-existence platforms (MRPs) are contemplated. Embodiments include transformations, code, state machines or other logic to determine an overlap between receiving by a wireless device of the MRP and transmitting by other of the wireless devices of the MRP and to select a link rate of the wireless device of the MRP based upon the determining an overlap. The embodiments may also include communicating the determined link rate to a wireless device transmitting to the wireless device of the MRP. Embodiments may also include selecting a previously used link rate if the receiving overlaps the transmitting. Embodiments may also include basing the link rate upon an overlapping or non-overlapping Signal-to-Interference-Plus-Noise-Ratio depending on the relative amounts of overlapping and non-overlapping.

International Classification:

H04L 12/28

US Classification:

370254, 370328, 455446

Abstract:

In general, in one aspect, the disclosure describes a method that includes selecting an offset between start of communications of a first radio in a multi-radio platform (MRP) and start of communications of a second radio in the MRP. Synchronizing clocks of the first radio and the second radio to maintain the offset. Determining safe zones within the communications of the second radio based on configuration of the first radio and the second radio and the selected offset. The safe zones are locations that minimize conflicts between receiving operations of the first radio that are at fixed locations and transmitting operations of the second radio and transmitting operations of the first radio that are at fixed locations and receiving operations of the second radio.

International Classification:

H04B 7/005
H04Q 7/24

US Classification:

370278, 370338

Abstract:

In general, in one aspect, the disclosure describes an apparatus that includes a first radio to communicate with a first wireless network and a second radio to communicate with a second wireless network. The first wireless network transmits a map defining locations within an assigned spectrum data is to be communicated therebetween. An earliest possible location defined in map is such that the map can be parsed within the time it would take to get to the earliest possible location so that the radio can be turned off after receiving the map until the location defined in the map, and the second radio is active when the first radio is not.

International Classification:

H04M 1/00

US Classification:

4555531, 4555521

Abstract:

Transmission opportunity (TXOP) duration is adapted for a wireless local area network (WLAN) transceiver in a dual radio wireless device based on an end of free time indication associated with a wireless wide area network (WWAN) transceiver within the same device. In this manner, the occurrence of collisions between WLAN communication activity and WLAN communication activity within the dual radio device may be reduced or eliminated.
