Time multiplexing for coexistence within multiple communication systems
View Patent ↗Methods and apparatus permitting the coexistence of multiple communication links to distinct wireless systems in a client device are disclosed. A wireless device can interface with both a primary communications system and at least one distinct communications system by managing the coexistence of active communications with the multiple communication systems. The wireless device can initially configure communications with the primary communications system for dynamically reconfigurable time multiplexed operation having scheduled periods of inactivity. The wireless device can determine timing and scheduling of communications with the distinct communications systems and can schedule the communications with the distinct communications systems during periods of inactivity in the primary communications system. The periods of inactivity may be limited to the scheduled periods of inactivity or can include unscheduled periods of inactivity occurring during active periods of the time multiplexed operation. The device may also use data priorities of communications to override overlapping communication activity.
1. A method of operating a communication device, the method comprising:
establishing a first communication link in a first band, the first communication link comprising an uplink portion of a frame;
establishing a second communication link in a second band;
determining a portion of time during which the uplink portion of the frame has no resource allocations;
scheduling a period for transmission during the portion of time in which the uplink portion of the frame has no resource allocations; and
transmitting a second communication over the second communication link during the period for transmission, wherein the second communication is scheduled to occur during the portion of time in which the uplink portion of the frame has no resource allocations and outside of a guard period of the portion of time in which the uplink portion of the frame has no resource allocations.
2. The method of claim 1 wherein the frame is an OFDMA frame.
3. The method of claim 1 wherein the determining is based on a MAP portion of the frame.
4. The method of claim 1 wherein the determining is based on a MAP portion of a second frame.
5. The method of claim 1 wherein the first communication link comprises Multicast and Broadcast Service (MBS) data in a downlink portion of the frame.
6. The method of claim 1 further comprising:
initiating a communication activity over the first communication link, the communication activity comprising a first intrinsic priority level;
providing a second intrinsic priority level relating to the second communication;
comparing the first intrinsic priority level to the second intrinsic priority level prior to determining the portion of time during which the uplink portion of the frame has no resource allocations; and
suppressing the second communication if the first intrinsic priority level exceeds the second intrinsic priority level.
7. A method of operating a communication device, the method comprising:
establishing a first communication link in a first band;
establishing a second communication link in a second band;
initiating a first communication activity over the first communication link, the first communication activity comprising a first priority level and further comprising an uplink portion of a frame;
providing a second communication activity for transmission over the second communication link, the second communication activity comprising a second priority level;
comparing the first priority level to the second priority level; and
based on the comparing:
if the first priority level exceeds the second priority level:
suppressing the second communication activity; and
if the first priority level does not exceed the second priority level:
determining a portion of time during which the uplink portion of the frame has no resource allocations;
scheduling a period for transmission during the portion of time in which the uplink portion of the frame has no resource allocations; and
transmitting the second communication activity over the second communication link during the period for transmission.
