Abstract

Claims (65)

1 . 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 a packet corresponding to a hybrid automatic repeat request (HARQ) process, wherein the packet comprises a medium access control (MAC) control element (CE), wherein the MAC CE indicates a value of a second time duration;

determine whether the MAC CE is retransmitted by a base station during the second time duration after receiving the MAC CE and before applying the MAC CE; and

in response to determining that the MAC CE is not retransmitted during the second time duration and based on whether a feedback of the HARQ process is enabled or disabled, apply the MAC CE after at least one of:

a first time duration starting from transmission of feedback of the packet; or

the second time duration starting from reception of the packet.

2 . The wireless device of claim 1 , wherein the packet is a MAC packet data unit (PDU).

3 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to receive one or more radio resource control (RRC) configuration parameters indicating whether the feedback of the HARQ process is enabled or disabled.

4 . The wireless device of claim 3 , wherein:

the applying the MAC CE is after the first time duration starting from transmission of the feedback of the packet based on the one or more RRC configuration parameters indicating the feedback of the HARQ process being enabled; and

the feedback of the packet is HARQ acknowledgement (ACK) information feedback of the packet.

5 . The wireless device of claim 3 , wherein the applying the MAC CE is after the second time duration starting from reception of the packet based on the one or more RRC configuration parameters indicating the feedback of the HARQ process being disabled.

6 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to:

based on the applying the MAC CE, implement a communication parameter indicated by the MAC CE; and

communicate, with the base station, based on the implemented communication parameter.

7 . The wireless device of claim 6 , wherein the implementing the communication parameter comprises at least one of:

altering a first configuration of the wireless device, wherein the first configuration of the wireless device is a first uplink configuration of the wireless device or a first downlink configuration of the wireless device;

adjusting a second configuration of the wireless device, wherein the second configuration of the wireless device is a second uplink configuration of the wireless device or a second downlink configuration of the wireless device; or

updating a third configuration of the wireless device, wherein the third configuration of the wireless device is a third uplink configuration of the wireless device or a third downlink configuration of the wireless device.

8 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to;

determine the packet not being retransmitted during the second time duration;

determine an application time of the MAC CE based on:

the feedback of the HARQ process being disabled; and

whether the MAC CE is retransmitted; and

apply the MAC CE based on the application time of the MAC CE; and

wherein the second time duration is for waiting for retransmission of the packet before applying the MAC CE.

9 . A method comprising:

receiving, by a wireless device, a packet corresponding to a hybrid automatic repeat request (HARQ) process, wherein the packet comprises a medium access control (MAC) control element (CE), wherein the MAC CE indicates a value of a second time duration;

determining whether the MAC CE is retransmitted by a base station during the second time duration after receiving the MAC CE and before applying the MAC CE; and

in response to determining that the MAC CE is not retransmitted during the second time duration and based on whether a feedback of the HARQ process is enabled or disabled, applying the MAC CE after at least one of:

a first time duration starting from transmission of feedback of the packet; or

the second time duration starting from reception of the packet.

10 . The method of claim 9 , wherein the packet is a MAC packet data unit (PDU).

11 . The method of claim 9 , further comprising receiving one or more radio resource control (RRC) configuration parameters indicating whether the feedback of the HARQ process is enabled or disabled.

12 . The method of claim 11 , wherein:

the applying the MAC CE is after the first time duration starting from transmission of the feedback of the packet based on the one or more RRC configuration parameters indicating the feedback of the HARQ process being enabled; and

the feedback of the packet is HARQ acknowledgement (ACK) information feedback of the packet.

13 . The method of claim 11 , wherein the applying the MAC CE is after the second time duration starting from reception of the packet based on the one or more RRC configuration parameters indicating the feedback of the HARQ process being disabled.

14 . The method of claim 9 , further comprising:

based on the applying the MAC CE, implementing a communication parameter indicated by the MAC CE; and

communicating, with the base station, based on the implemented communication parameter.

15 . The method of claim 14 , wherein the implementing the communication parameter comprises at least one of:

altering a first configuration of the wireless device, wherein the first configuration of the wireless device is a first uplink configuration of the wireless device or a first downlink configuration of the wireless device;

adjusting a second configuration of the wireless device, wherein the second configuration of the wireless device is a second uplink configuration of the wireless device or a second downlink configuration of the wireless device; or

updating a third configuration of the wireless device, wherein the third configuration of the wireless device is a third uplink configuration of the wireless device or a third downlink configuration of the wireless device.

16 . The method of claim 9 , further comprising:

determining the packet not being retransmitted during the second time duration;

determining an application time of the MAC CE based on:

the feedback of the HARQ process being disabled; and

whether the MAC CE is retransmitted; and

applying the MAC CE based on the application time of the MAC CE; and

wherein the second time duration is for waiting for retransmission of the packet before applying the MAC CE.

17 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

receive a packet corresponding to a hybrid automatic repeat request (HARQ) process, wherein the packet comprises a medium access control (MAC) control element (CE), wherein the MAC CE indicates a value of a second time duration;

determine whether the MAC CE is retransmitted by a base station during the second time duration after receiving the MAC CE and before applying the MAC CE; and

in response to determining that the MAC CE is not retransmitted during the second time duration and based on whether a feedback of the HARQ process is enabled or disabled, apply the MAC CE after at least one of:

a first time duration starting from transmission of feedback of the packet; or

the second time duration starting from reception of the packet.

18 . The non-transitory computer-readable medium of claim 17 , wherein the packet is a MAC packet data unit (PDU).

19 . The non-transitory computer-readable medium of claim 17 , wherein the instructions further cause the wireless device to receive one or more radio resource control (RRC) configuration parameters indicating whether the feedback of the HARQ process is enabled or disabled.

20 . The non-transitory computer-readable medium of claim 19 , wherein:

the applying the MAC CE is after the first time duration starting from transmission of the feedback of the packet based on the one or more RRC configuration parameters indicating the feedback of the HARQ process being enabled; and

the feedback of the packet is HARQ acknowledgement (ACK) information feedback of the packet.
