Radio link control (RLC) status reporting

1. A method of wireless communication performed by a wireless communication device, comprising:

receiving one or more radio link control (RLC) packet data units (PDUs) of a sequence of RLC PDUs;

determining missing RLC PDUs in the sequence of RLC PDUs based on the received one or more RLC PDUs;

receiving a first uplink (UL) grant;

transmitting a communication signal including a buffer status report (BSR) and a first RLC status report including an indication of a first subset of the missing RLC PDUs less than all the missing RLC PDUs, the indication of the first subset of missing PDUs being based on a size of the first UL grant, the BSR being based on a RLC status report size for indicating all the missing RLC PDUs in the sequence of RLC PDUs; and

modifying a RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.

2. The method of claim 1 , wherein the modifying the RLC status prohibit timer comprises:

refraining from starting the RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.

3. The method of claim 1 , wherein the modifying the RLC status prohibit timer comprises:

selecting a RLC status timer value between a first RLC status timer value and a second RLC status timer value based on the transmitted first RLC status report indicating less than all the missing RLC PDUs, wherein the first RLC status timer value is less than the second RLC status timer value.

4. The method of claim 1 , wherein the sequence of RLC PDUs is associated with a RLC receive window.

5. The method of claim 1 , further comprising:

generating the first RLC status report, wherein a size of the first RLC status report is based on the size of the UL grant.

6. The method of claim 1 , further comprising:

receiving a second UL grant after the first UL grant; and

transmitting a second RLC status report including an indication of a second subset of the missing RLC PDUs including the first subset of the missing RLC PDUs based on the second UL grant.

7. The method of claim 6 , further comprising:

starting the RLC status prohibit timer based on a determination that the second subset of the missing RLC PDUs in the second RLC status report includes all the missing RLC PDUs in the sequence of RLC PDUs.

8. The method of claim 1 , further comprising:

transmitting, after transmitting the first RLC status report, the BSR based on a RLC status report size for indicating all the missing RLC PDUs in the sequence of RLC PDUs.

9. The method of claim 1 , wherein the transmitting the first RLC status report comprises:

transmitting, while in a RLC status report triggered state, the first RLC status report; and

the method further comprises:

determining to remain in the RLC status report triggered state based on the first RLC status report indicating less than all the missing RLC PDUs in the sequence of RLC PDUs.

10. A wireless communication device comprising:

a memory;

a transceiver; and

at least one processor coupled to the memory and, wherein the wireless communication device is configured to:

receive one or more radio link control (RLC) packet data units (PDUs) of a sequence of RLC PDUs;

determine missing RLC PDUs in the sequence of RLC PDUs based on the received one or more RLC PDUs;

receive a first uplink (UL) grant;

transmit a communication signal including a buffer status report (BSR) and a first RLC status report including an indication of a first subset of the missing RLC PDUs less than all the missing RLC PDUs, the indication of the first subset of missing PDUs being based on a size of the first UL grant, the BSR being based on a RLC status report size for indicating all the missing RLC PDUs in the sequence of RLC PDUs; and

modify a RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.

11. The wireless communication device of claim 10 , wherein the wireless communication device is further configured to:

refrain from starting the RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.

12. The wireless communication device of claim 10 , wherein the wireless communication device is further configured to:

select a RLC status timer value between a first RLC status timer value and a second RLC status timer value based on the transmitted first RLC status report indicating less than all the missing RLC PDUs, wherein the first RLC status timer value is less than the second RLC status timer value.

13. The wireless communication device of claim 10 , wherein the sequence of RLC PDUs is associated with a RLC receive window.

14. The wireless communication device of claim 10 , wherein the wireless communication device is further configured to:

generate the first RLC status report, wherein a size of the first RLC status report is based on the size of the UL grant.

15. The wireless communication device of claim 10 , wherein the wireless communication device is further configured to:

transmit, while in a RLC status report triggered state, the first RLC status report; and

determine to remain in the RLC status report triggered state based on the first RLC status report indicating less than all the missing RLC PDUs in the sequence of RLC PDUs.
