Abstract

Methods and apparatus of wireless communication at a user equipment comprise compressing an uplink data packet. The methods and apparatus further comprise transmitting the uplink data packet on an uplink dedicated transport channel (DCH) to a network entity a plurality of times within a time duration allowed for transmission of the uncompressed uplink data packet. Moreover, the methods and apparatus comprise receiving a downlink acknowledgement message from the network entity corresponding to the uplink data packet. Additionally, the methods and apparatus comprise terminating transmission of the uplink DCH by transmitting bits of zero power for a remainder of the time duration on the DCH based on receiving the downlink acknowledgement message.

First claim

What is claimed is:

1. A method of wireless communication at a user equipment, comprising:
compressing an uplink data packet;
transmitting the uplink data packet on an uplink dedicated transport channel (DCH) to a network entity a plurality of times within a time duration allowed for transmission of the uncompressed uplink data packet;
wherein compressing the uplink data packet comprises reducing a transmission time interval (TTI) by a factor of n and the plurality of times comprises n times;
receiving a downlink acknowledgement message from the network entity corresponding to the uplink data packet; and
terminating transmission of the uplink DCH by transmitting bits of zero power for a remainder of the time duration on the DCH based on receiving the downlink acknowledgement message.

2. The method of claim 1 , further comprising:
receiving, from the network entity, an uplink power control message, wherein the network entity determines contents of the uplink power control message based on at least a signal-to-interference ratio (SIR) target value; and
adjusting an uplink transmission power corresponding to the data channel according to the uplink power control message.

3. The method of claim 2 , wherein the SIR target value is based on a target residual block error rate (BLER) associated with a particular decoding attempt.

4. The method of claim 3 , wherein at least one of the target residual BLER and the particular decoding attempt at which the target residual BLER is targeted are based on at least one of uplink load measured at the network entity and user equipment power headroom.

5. The method of claim 1 , further comprising:
establishing a new uplink channel;
receiving a downlink data packet on the DCH;
decoding the downlink data packet successfully;
transmitting an uplink acknowledgement message corresponding to the downlink data packet to the network entity on the new uplink channel based on receiving the downlink data packet and decoding the downlink data packet successfully; and
terminating uplink communication on a control channel based on transmitting the uplink acknowledgement message.

6. The method of claim 5 , further comprising powering down a transmitter based on receiving the downlink acknowledgement message and decoding the downlink data packet successfully.

7. The method of claim 5 , wherein the new uplink channel comprises a Transport Format Combination Indicator (TFCI).

8. The method of claim 5 , further comprising configuring the control channel with a slot format that does not include TFCI bits.

9. The method of claim 1 , wherein the uplink data packet comprises voice data.

means for receiving, from the network entity, an uplink power control message, wherein the network entity determines contents of the uplink power control message based on at least a signal-to-interference ratio (SIR) target value; and
means for adjusting an uplink transmission power corresponding to the data channel according to the uplink power control message.

12. The apparatus of claim 10 , further comprising:
means for establishing a new uplink channel;
means for receiving a downlink data packet on the DCH;
means for decoding the downlink data packet successfully;
means for transmitting an uplink acknowledgement message corresponding to the downlink data packet to the network entity on the new uplink channel based on receiving the downlink data packet and decoding the downlink data packet successfully; and
means for terminating uplink communication on a control channel based on transmitting the uplink acknowledgement message.

13. A computer program product, comprising:
a computer-readable medium comprising code for:
compressing an uplink data packet;
