Network node, UE and methods performed therein for handling communication

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, indicating a buffer status of the UE by using an SR resource having a value of a cyclic shift masking a physical uplink control channel, PUCCH SR, the value being selected from a plurality of values, the plurality of values being based on a number of buffer thresholds configured for the UE, the buffer status indicating a level of buffer, the level of the buffer being conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within a sequence group.

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. 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, indicating a buffer status of the UE by an SR resource having a value of a cyclic shift masking a physical uplink control channel, PUCCH SR, the value being selected from a plurality of values, the plurality of values being based on a number of buffer thresholds configured for the UE, the buffer status indicating a level of buffer, the level of the buffer being conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within a sequence group; and

handling communication of the UE based on the SR and the indicated buffer status.

5. The method according to claim 4 , wherein the SR indicates the buffer status by itself.

6. The method according to claim 4 , wherein the SR comprises one or more bits indicating the buffer status.

7. The method according to claim 4 , wherein handling communication comprises granting resources based on the SR and the indicated buffer status.

8. 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, indicating a buffer status of the UE by using an SR resource having a value of a cyclic shift masking a physical uplink control channel, PUCCH SR, the value being selected from a plurality of values, the plurality of values being based on a number of buffer thresholds configured for the UE, the buffer status indicating a level of buffer, the level of the buffer being conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within a sequence group.

9. The UE according to claim 8 , wherein the SR indicates the buffer status by itself.

10. The UE according to claim 8 , wherein the SR comprises one or more bits indicating the buffer status.

11. 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 by using an SR resource having a value of a cyclic shift masking a physical uplink control channel, PUCCH SR, the value being selected from a plurality of values, the plurality of values being based on a number of buffer thresholds configured for the UE, the buffer status indicating a level of buffer, the level of the buffer being conveyed using different physical uplink control channel, PUCCH, sequence group numbers u and sequence numbers v within a sequence group; and

handling communication of the UE based on the SR and the indicated buffer status.

12. The network node according to claim 11 , wherein the SR indicates the buffer status by itself.

13. The network node according to claim 11 , wherein the SR comprises one or more bits indicating the buffer status.
