Abstract

Apparatus, and an associated method, that facilitates communication of data in a radio communication system that utilizes a slotted communication scheme. Multiple successive time slots are allocable upon which to communicate data to a receiving communication station. At selected intervals, a controller causes the mode of operation of the receiving communication station to be changed to pause operation in a receive mode and, during the pause, to cause operation of the receiving communication station to transmit data, such as control acknowledgments or other responses.

Claims

1. A method, comprising:

receiving, at a device from a network, an allocation of a plurality of first timeslots for data reception at the device;

receiving, from the network, an allocation of one or more second timeslots for data transmission at the device, wherein the allocation of one or more second timeslots comprises at least one timeslot, and wherein a data transmission by the device on the at least one timeslot would cause the device to pause data reception on at least one of the plurality of first timeslots to conform to a time requirement for switching between different modes of operation of the device;

receiving data from the network on one or more of the plurality of first timeslots during a frame or a group of frames; and

transmitting data to the network on the at least one timeslot of the one or more second timeslots during the frame or the group of frames.

2. The method of claim 1, further comprising transmitting an indication of transmit and receive capabilities of the device.

3. The method of claim 1, further comprising transmitting an indication of capabilities of the device to pause data reception operations and send control acknowledgments or other data to the network for selected time periods.

4. The method of claim 1, wherein the transmitting comprises sending at least one of traffic data and an acknowledgment of received data on the at least one timeslot of the one or more second timeslots.

5. The method of claim 1, further comprising monitoring the plurality of first timeslots upon completion of the transmitting.

6. The method of claim 1, wherein pausing data reception comprises pausing for a duration to transmit on the at least one timeslot of the one or more second timeslots and to conform to a device reaction time requirement.

7. The method of claim 1, wherein pausing data reception comprises pausing for a period to transmit on the at least one timeslot of the one or more second timeslots and to change into and out of an operational mode to permit the transmitting.

8. The method of claim 1, wherein the allocation of the plurality of first timeslots and the allocation of the one or more second timeslots enable the device to pause data reception after a first time period.

9. The method of claim 1, wherein transmitting on the at least one timeslot of the one or more second timeslots is responsive to receiving an uplink state flag.

10. The method of claim 1, further comprising, after the transmitting, resuming data reception on a first one of the plurality of first timeslots.

11. The method of claim 1, wherein the allocation of the plurality of first timeslots and the allocation of the one or more second timeslots enable the device to resume data reception after a second time period.

12. The method of claim 1, wherein the plurality of first timeslots comprises an entire frame, and the method further comprises transmitting an indication of capabilities of the device to perform reception on the entire frame.

13. The method of claim 1, wherein the switching between different modes of operation of the device comprises switching between a mode of operation for data reception and a mode of operation for data transmission.

14. The method of claim 1, wherein the switching between different modes of operation of the device comprises performing a cell measurement.

15. A device, comprising:

at least one hardware processor; and

a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the at least one hardware processor to perform operations comprising;

receiving, at the device from a network, an allocation of a plurality of first timeslots for data reception at the device;

receiving, from the network, an allocation of one or more second timeslots for data transmission at the device, wherein the allocation of one or more second timeslots comprises at least one timeslot, and wherein a data transmission by the device on the at least one timeslot would cause the device to pause data reception on at least one of the plurality of first timeslots to conform to a time requirement for switching between different modes of operation of the device;

receiving data from the network on one or more of the plurality of first timeslots during a frame or a group of frames; and

transmitting data to the network on the at least one timeslot of the one or more second timeslots during the frame or the group of frames.

16. The device of claim 15, the operations further comprising transmitting an indication of transmit and receive capabilities of the device.

17. The device of claim 15, the operations further comprising transmitting an indication of capabilities of the device to pause data reception operations and send control acknowledgments or other data to the network for selected time periods.

18. The device of claim 15, wherein the transmitting comprises sending at least one of traffic data and an acknowledgment of received data on the at least one timeslot of the one or more second timeslots.

19. The device of claim 15, the operations further comprising monitoring the plurality of first timeslots upon completion of the transmitting.

20. A non-transitory computer-readable medium storing instructions which, when executed, cause a device to perform operations comprising:

receiving, at the device from a network, an allocation of a plurality of first timeslots for data reception at the device;

receiving, from the network, an allocation of one or more second timeslots for data transmission at the device, wherein the allocation of one or more second timeslots comprises at least one timeslot, and wherein a data transmission by the device on the at least one timeslot would cause the device to pause data reception on at least one of the plurality of first timeslots to conform to a time requirement for switching between different modes of operation of the device;

receiving data from the network on one or more of the plurality of first timeslots during a frame or a group of frames; and

transmitting data to the network on the at least one timeslot of the one or more second timeslots during the frame or the group of frames.
