Patent ID: 8207937

Claim:
A communication protocol for use in a wireless network, the wireless network having a transceiver and a plurality of wireless input devices, at least one wireless input device configured as an unidirectional device and at least one other wireless input device configured as a bidirectional device, the communication protocol comprising: a unidirectional mode for communication from the unidirectional device to the transceiver; and a bidirectional mode for communication between the bidirectional device and the transceiver, the communication being either bidirectional or unidirectional, wherein a size of reports transmitted by a first wireless input device to the transceiver is negotiated between the first device and the transceiver, the negotiation comprising: transmitting, by the first device to the transceiver, a size adjustment request with a requested size, and responsive to the transceiver accepting the request, transmitting, by the transceiver to the first device, a response report at the requested size, and wherein responsive to a first report transmitted to the transceiver by the first device at the requested size colliding with a second report transmitted to the transceiver by a second wireless input device, the first device retransmitting the first report, the timing for initiating the retransmission being based on a type of the first device, each device type having a different timing for initiating retransmissions.
