Abstract:
1. An apparatus configured to be implemented in a first wireless communication device, wherein the apparatus comprises: a memory configured to store a coexistence schedule, wherein the coexistence schedule defines wireless local-area network (WLAN) intervals and non-WLAN intervals; a WLAN transceiver configured to transmit WLAN signals in an independent basic service set (IBSS) network; a non-WLAN transceiver configured to transmit wireless non-WLAN signals; and a coexistence circuit configured to allow the WLAN transceiver to transmit the WLAN signals in the IBSS network only during the WLAN intervals, wherein the coexistence circuit is further configured to allow the non-WLAN transceiver to transmit the wireless non-WLAN signals only during the non-WLAN intervals; and wherein the coexistence circuit is further configured to cause the WLAN transceiver to transmit a coexistence request message, prior to each of the non-WLAN intervals, to one or more second wireless communication devices in the IBSS network, wherein each of the coexistence request messages indicates a duration of a respective one of the non-WLAN intervals, to prevent the one or more second wireless communication devices from transmitting during the respective one of the non-WLAN intervals.
