Abstract

In a method of wireless communication, a grant allocating a plurality of high speed subframes for high speed data channels is received before a measurement gap for tuning away from a serving radio access technology (RAT). At least one high speed subframe is allocated in the grant falling within the measurement gap. High speed data is processed only on high speed subframes of the plurality of high speed subframes before and after the measurement gap. An acknowledgement/negative acknowledgement (ACK/NACK) feedback is transmitting and only the high speed subframes of the plurality of high speed subframes before and after the measurement gap are considered.

Claims

1. A method of wireless communication, comprising:

receiving a grant allocating a plurality of high speed subframes for high speed data channels, the grant being received before a measurement gap for tuning away from a serving radio access technology (RAT), and at least one high speed subframe allocated in the grant falling within the measurement gap;

processing high speed data, by a user equipment (UE), only on high speed subframes of the plurality of high speed subframes before and after the measurement gap; and

transmitting acknowledgement/negative acknowledgement (ACK/NACK) feedback, by the UE, only considering the high speed subframes of the plurality of high speed subframes before and after the measurement gap.

2. The method of claim 1, in which processing the high speed data comprises receiving high speed downlink data.

3. The method of claim 1, in which processing the high speed data comprises transmitting high speed uplink packet data.

4. The method of claim 3, further comprising receiving ACK/NAK feedback in response to the transmitted high speed uplink packet data.

5. The method of claim 4, in which the transmitted ACK/NAK feedback comprises a bundled ACK/NAK bit or a multiplexed ACK/NAK bit.

6. The method of claim 1, in which the transmitted ACK/NAK feedback comprises a bundled ACK/NAK bit or a multiplexed ACK/NAK bit.

7. A method of wireless communication, comprising:

transmitting a grant allocating a plurality of high speed subframes for high speed data channels, the grant being transmitted before a measurement gap for tuning away from a serving radio access technology (RAT), and at least one high speed subframe allocated in the grant falling within the measurement gap;

processing high speed data, by a NodeB, only on high speed subframes of the plurality of high speed subframes before and after the measurement gap; and

receiving acknowledgement/negative acknowledgement (ACK/NACK) feedback, by the NodeB, only for the high speed subframes of the plurality of high speed subframes before and after the measurement gap.

8. The method of claim 7, in which processing the high speed data comprises receiving high speed uplink packet data.

9. The method of claim 8, further comprising transmitting ACK/NAK feedback in response to the received high speed uplink packet data.

10. The method of claim 9, in which the transmitted ACK/NAK feedback comprises a bundled ACK/NAK bit or a multiplexed ACK/NAK bit.

11. The method of claim 7, in which processing the high speed data comprises transmitting high speed downlink data.

12. The method of claim 7, in which the received ACK/NAK feedback comprises a bundled ACK/NAK bit or a multiplexed ACK/NAK bit.

13. An apparatus for wireless communication, comprising:

a memory unit; and

at least one processor coupled to the memory unit, the at least one processor being configured;

to receive a grant allocating a plurality of high speed subframes for high speed data channels, the grant being received before a measurement gap for tuning away from a serving radio access technology (RAT), and at least one high speed subframe allocated in the grant falling within the measurement gap;

19. An apparatus for wireless communication, comprising:

a memory unit; and

at least one processor coupled to the memory unit, the at least one processor being configured;

to transmit a grant allocating a plurality of high speed subframes for high speed data channels, the grant being transmitted before a measurement gap for tuning away from a serving radio access technology (RAT), and at least one high speed subframe allocated in the grant falling within the measurement gap;
