Abstract

Methods of wireless communication between a gaming console and a wireless accessory using a protocol. The protocol is used in a TDMA frequency hopping spread spectrum system to enable simultaneous communication of voice and data between a plurality of wireless accessories and the gaming console. The protocol provides specific time slots for upstream and downstream transmissions, as well as a retransmission time slots to enable a robust environment with minimal latency.

Claims

1. A method of communicating between a gaming console and a wireless accessory using a wireless protocol wherein said gaming console and said wireless accessory transmit and receive based on a time frame, said method comprising:

transmitting an upstream data packet in an upstream sub frame from said wireless accessory to said gaming console, said upstream data packet comprising a first upstream data sub packet and a first upstream voice sub packet;

receiving at least one of a downstream voice packet and a downstream data packet in a downlink sub frame from said gaming console;

wherein voice data and wireless accessory data are simultaneously communicated via said wireless protocol, and wherein transmission of each packet is in a frequency hopping spread spectrum system on a different frequency associated with a Time Division Multiple Access (TDMA) time slot;

assigning said first upstream data sub packet and said first upstream voice sub packet a first time slot; and

assigning a subsequent upstream data packet that comprises a subsequent data sub packet and a subsequent upstream voice sub packet to a subsequent time slot.

2. The method of claim 1, further comprising:

transmitting, from a first wireless accessory, wireless accessory data in said first upstream data sub packet; and

transmitting, from a second voice-enabled device, voice data in said first upstream voice sub packet.

3. The method of claim 1, wherein said upstream and downstream voice and data packets each comprise an RF setup field, a preamble field, a sync field, a header field, a data field, and an error correction field.

4. The method of claim 1, further comprising communicating said voice data in said downstream voice packet to a plurality of voice-enabled devices.

5. The method of claim 4, further comprising communicating a plurality of downstream voice packets in said downlink sub frame.

6. The method of claim 1, further comprising:

broadcasting, from said gaming console, said downstream data packet to a plurality of wireless accessories, said downstream data packet comprising predetermined data sub fields containing data for each of said plurality of wireless accessories.

7. The method of claim 1, further comprising:

transmitting an uplink retransmission packet from said wireless accessory only if an acknowledgement is not received from said gaming console in said downlink sub frame.

8. The method of claim 1, further comprising broadcasting a downlink retransmission packet to a plurality of wireless accessories.
