Discontinuous reception and CSI
A wireless device receives one or more messages. The one or more messages comprise discontinuous reception configuration parameters comprising a value for a discontinuous reception inactivity timer. A first downlink control information is received that indicates a channel state information request; and no uplink packet transmission. The discontinuous reception inactivity timer is started in response to the first downlink control information indicating the channel state information request and no uplink packet transmission. A second downlink control information is received while the discontinuous reception inactivity timer is running. One or more transport blocks is transmitted based on the second downlink control information.
1. A method comprising:
receiving, by a wireless device, one or more messages comprising:
discontinuous reception configuration parameters comprising a value for a discontinuous reception inactivity timer; and
a semi-persistent channel state information (SP-CSI) radio network temporary identifier (RNTI);
receiving a first downlink control information (DCI) corresponding to the SP-CSI RNTI indicating:
activation of an SP-CSI reporting; and
no uplink grant for uplink packet transmission;
starting the discontinuous reception inactivity timer in response to the first downlink control information indicating the activation of the SP-CSI reporting and no uplink grant, wherein the discontinuous reception inactivity timer is used for controlling monitoring for DCIs of the SP-CSI RNTI;
receiving a second DCI while the discontinuous reception inactivity timer is running; and
transmitting one or more transport blocks based on the second DCI.
2. The method of claim 1 , wherein:
the one or more messages comprise a plurality of channel state information trigger states indicating a plurality of channel state information reporting configurations.
3. The method of claim 2 , further comprising measuring channel state information reference signals, based on the channel state reporting configuration, in response to receiving the first DCI.
4. The method of claim 2 , further comprising monitoring a control channel in response to the discontinuous reception inactivity timer running.
5. The method of claim 2 , further comprising transmitting channel state information without the uplink packet in response the receiving the first DCI.
6. The method of claim 1 , wherein the starting the discontinuous reception inactivity timer is with the value.
7. The method of claim 1 , wherein the first DCI indicates resources for transmission of channel state information.
8. The method of claim 1 , wherein the first DCI indicates transmission of channel state information via a physical uplink shared channel.
9. The method of claim 1 , wherein the wireless device is in discontinuous reception active time in response to discontinuous reception inactivity timer running.
10. The method of claim 1 , further comprising monitoring a control channel in response to the discontinuous reception inactivity timer running.
11. The method of claim 1 , further comprising transmitting channel state information without the uplink packet in response the receiving the first DCI.
12. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive one or more messages comprising:
discontinuous reception configuration parameters comprising a value for a discontinuous reception inactivity timer; and
a semi-persistent channel state information (SP-CSI) radio network temporary identifier (RNTI);
receive a first downlink control information (DCI) corresponding to the SP-CSI RNTI indicating:
activation of an SP-CSI reporting; and
no uplink grant for uplink packet transmission;
start the discontinuous reception inactivity timer in response to the first downlink control information indicating the activation of the SP-CSI reporting and no uplink grant, wherein the discontinuous reception inactivity timer is used for controlling monitoring for DCIs of the SP-CSI RNTI;
receive a second DCI while the discontinuous reception inactivity timer is running; and
transmit one or more transport blocks based on the second DCI.
13. The method of claim 1 , wherein the first DCI indicates resources for transmission of channel state information.
14. The method of claim 1 , wherein the first DCI indicates transmission of channel state information via a physical uplink shared channel.
15. The method of claim 1 , wherein the wireless device is in discontinuous reception active time in response to discontinuous reception inactivity timer running.
16. The method of claim 1 , further comprising monitoring a control channel in response to the discontinuous reception inactivity timer running.
17. The method of claim 1 , further comprising transmitting channel state information without the uplink packet in response the receiving the first DCI.
18. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:
receive one or more messages comprising:
discontinuous reception configuration parameters comprising a value for a discontinuous reception inactivity timer; and
a semi-persistent channel state information (SP-CSI) radio network temporary identifier (RNTI);
receive a first downlink control information (DCI) corresponding to the SP-CSI RNTI indicating:
activation of an SP-CSI reporting; and
no uplink grant for uplink packet transmission;

receive a second DCI while the discontinuous reception inactivity timer is running; and
transmit one or more transport blocks based on the second DCI.
19. The method of claim 1 , wherein the first DCI indicates resources for transmission of channel state information.
20. The method of claim 1 , wherein the first DCI indicates transmission of channel state information via a physical uplink shared channel.
