Abstract

Embodiments herein relate to e.g., a method performed by a UE for handling communication of data in a wireless communication network. The UE transmits a scheduling request, SR, indicating a buffer status of the UE or along with an indication indicating the buffer status of the UE.

First claim

1 . A method performed by a user equipment, UE, for handling communication of data in a wireless communication network, the method comprising:
transmitting, to a network node, a scheduling request, SR, one of indicating a buffer status of the UE and along with an indication indicating the buffer status of the UE, the buffer status being indicated by using at least one of:
one or multiple SR resources with values of different cyclic shifts; and
different orthogonal covering codes masking over physical uplink control channel, PUCCH, SR; and
the values of different cyclic shifts masking PUCCH SR depending on a number of buffer thresholds configured for the UE.

2 . The method according to claim 1 , wherein the SR indicates the buffer status by itself.

3 . The method according to claim 1 , wherein the SR comprises one or more bits indicating the buffer status.

4 . The method according to claim 1 , wherein the buffer status is indicating a level of buffer.

5 . The method according to claim 4 , wherein the level of the buffer is conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within the group.

6 .- 8 . (canceled)

9 . A method performed by a network node for handling communication of data of a user equipment, UE, in a wireless communication network, the method comprising
receiving, from the UE, a scheduling request, SR, one of indicating a buffer status of the UE and along with an indication indicating the buffer status of the UE; and handling communication of the UE based on the SR and the indicated buffer status, the buffer status being indicated by using at least one of:
one or multiple SR resources with values of different cyclic shifts; and
different orthogonal covering codes masking over physical uplink control channel, PUCCH, SR; and
the values of different cyclic shifts masking PUCCH SR depending on a number of buffer thresholds configured for the UE.

10 . The method according to claim 9 , wherein the SR indicates the buffer status by itself.

11 . The method according to claim 9 , wherein the SR comprises one or more bits indicating the buffer status.

12 . The method according to claim 9 , wherein the buffer status is indicating a level of buffer.

13 . The method according to claim 12 , wherein the level of the buffer is conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within the group.

14 .- 16 . (canceled)

17 . The method according to claim 9 , wherein handling communication comprises granting resources based on the SR and the indicated buffer status.

18 . (canceled)

19 . (canceled)

20 . A user equipment, UE, for handling communication of data in a wireless communication network, the UE being configured to:
transmit, to a network node, a scheduling request, SR, one of indicating a buffer status of the UE and along with an indication indicating the buffer status of the UE, the buffer status being indicated by using at least one of:
one or multiple SR resources with values of different cyclic shifts; and
different orthogonal covering codes masking over physical uplink control channel, PUCCH, SR; and
the values of different cyclic shifts masking PUCCH SR depending on a number of buffer thresholds configured for the UE.

21 . The UE according to claim 20 , wherein the SR indicates the buffer status by itself.

22 . The UE according to claim 20 , wherein the SR comprises one or more bits indicating the buffer status.

23 . The UE according to claim 20 , wherein the buffer status is indicating a level of buffer.

24 . The UE according to claim 23 , wherein the UE is configured to convey the level of the buffer using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within the group.

25 .- 27 . (canceled)

28 . A network node for handling communication of data of a user equipment, UE, in a wireless communication network, the network node being configured to
receive, from the UE, a scheduling request, SR, one of indicating a buffer status of the UE and along with an indication indicating the buffer status of the UE; and handle communication of the UE based on the SR and the indicated buffer status, the buffer status being indicated by using at least one of:
one or multiple SR resources with values of different cyclic shifts; and
different orthogonal covering codes masking over physical uplink control channel, PUCCH, SR; and
the values of different cyclic shifts masking PUCCH SR depending on a number of buffer thresholds configured for the UE.

29 . The network node according to claim 28 , wherein the SR indicates the buffer status by itself.

30 . The network node according to claim 28 , wherein the SR comprises one or more bits indicating the buffer status

31 . The network node according to claim 28 , wherein the buffer status is indicating a level of buffer, and wherein the level of the buffer is conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within the group.

32 .- 36 . (canceled)
