Method and apparatus for controlling uplink transmission on discontinuous reception operation in wireless communication system
A method for controlling uplink transmissions on discontinuous reception (DRX) operation, by a wireless device, in a wireless communication system, the method comprising: configuring a channel quality indicator (CQI)-masking which indicates that at least one of a CQI, a precoding matrix index (PMI), a rank indicator (RI), or a precoding type indicator (PTI) is not to be reported on a physical uplink control channel (PUCCH) when an onDurationTimer is not running; and determining, at a first subframe prior to a second subframe, whether or not the onDurationTimer is to be running at the second subframe, wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.
1. A method for controlling uplink transmissions on discontinuous reception (DRX) operation, by a wireless device, in a wireless communication system, the method comprising:
configuring a channel quality indicator (CQI)-masking which indicates that at least one of a CQI, a precoding matrix index (PMI), a rank indicator (RI), or a precoding type indicator (PTI) is not to be reported on a physical uplink control channel (PUCCH) when an onDurationTimer is not running; and
determining, at a first subframe prior to a second subframe, whether or not the onDurationTimer is to be running at the second subframe,
wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.
2. The method of claim 1 , wherein the CQI-masking is configured by upper layers.
3. The method of claim 1 , wherein none of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.
4. The method of claim 1 , wherein whether or not the onDurationTimer is to be running at the second subframe is determined according to whether or not radio resource allocation information is received through a physical downlink control channel (PDCCH) at the first subframe.
5. The method of claim 4 , wherein the onDurationTimer is determined to be not running at the second subframe if the radio resource allocation information is not received at the first subframe.
6. The method of claim 4 , further comprising receiving the radio resource allocation information through the PDCCH at a third subframe between the first subframe and the second subframe.
7. The method of claim 6 , wherein the onDurationTimer is determined to be running at the second subframe by the radio resource allocation information received at the third subframe.
8. The method of claim 7 , wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, without considering the radio resource allocation information received at the third subframe.
9. The method of claim 1 , wherein the first subframe is in a preparation time.
10. The method of claim 1 , wherein the second subframe is in a processing time.
11. A wireless device configured for controlling uplink transmissions on discontinuous reception (DRX) operation in a wireless communication system, the wireless device comprising:
a memory;
a radio frequency (RF) unit; and
a processor, operatively coupled to the memory and the RF unit, that:
configure a channel quality indicator (CQI)-masking which indicates that at least one of a CQI, a precoding matrix index (PMI), a rank indicator (RI), or a precoding type indicator (PTI) is not to be reported on a physical uplink control channel (PUCCH) when an onDurationTimer is not running, and
determine, at a first subframe prior to a second subframe, whether or not the onDurationTimer is to be running at the second subframe,
wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.
12. The wireless device of claim 11 , wherein the CQI-masking is configured by upper layers.
13. The wireless device of claim 11 , wherein none of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.
14. The wireless device of claim 11 , wherein whether or not the onDurationTimer is to be running at the second subframe is determined according to whether or not radio resource allocation information is received through a physical downlink control channel (PDCCH) at the first subframe.
15. The wireless device of claim 14 , wherein the onDurationTimer is determined to be not running at the second subframe if the radio resource allocation information is not received at the first subframe.
16. The wireless device of claim 14 , wherein the processor further controls the RF unit to receive the radio resource allocation information through the PDCCH at a third subframe between the first subframe and the second subframe.
17. The wireless device of claim 16 , wherein the onDurationTimer is determined to be running at the second subframe by the radio resource allocation information received at the third subframe.
18. The wireless device of claim 17 , wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, without considering the radio resource allocation information received at the third subframe.
19. The wireless device of claim 11 , wherein the first subframe is in a preparation time.
20. The wireless device of claim 11 , wherein the second subframe is in a processing time.
