Abstract

A method may include multiplexing, by a wireless device, a radio resource control, RRC, message in a medium access control protocol data unit, MAC PDU. The RRC message may indicate arrival of non-small data transmission, SDT, data. The multiplexing may be based on a logical channel prioritization order indicating that the RRC message is higher priority than data of an SDT procedure. The method may also include transmitting, by the wireless device, the MAC PDU.

Claims (46)

1 . A method comprising:

multiplexing, by a wireless device, a radio resource control, RRC, message in a medium access control protocol data unit, MAC PDU, wherein:

the RRC message indicates arrival of non-small data transmission, SDT, data; and

the multiplexing is based on a logical channel prioritization order indicating that the RRC message is higher priority than data of an SDT procedure; and

transmitting, by the wireless device, the MAC PDU.

2 . The method of claim 1 , wherein the data of the SDT procedure is data of an uplink dedicated traffic channel, UL DTCH.

3 . The method of claim 1 , wherein the logical channel prioritization order indicates that the RRC message is higher priority over a second RRC message of the data of the SDT procedure.

4 . The method of claim 3 , wherein the second RRC message is associated with an uplink dedicated control channel, UL DCCH, for transmitting the RRC message.

5 . The method of claim 1 , wherein the logical channel prioritization order indicates that the RRC message is:

higher priority than a cell radio network temporary identifier medium access control control element, C-RNTI MAC CE; or

equal priority to the C-RNTI MAC CE.

6 . The method of claim 1 , wherein the logical channel prioritization order indicates that the RRC message is higher priority than one or more medium access control control element, MAC CEs, comprising at least one of:

a beam failure recovery (BFR) MAC CE;

a MAC CE for a buffer status report (BSR);

a power headroom report (PHR) MAC CE; and

a listen before talk (LBT) failure MAC CE.

7 . The method of claim 1 , wherein the multiplexing and/or the transmitting is during the SDT procedure.

8 . The method of claim 1 , wherein the wireless device determines to transmit, during the SDT procedure, the RRC message indicating arrival of non-SDT data.

9 . The method of claim 1 , wherein the RRC message is for transmission via an uplink dedicated control channel, UL DCCH.

10 . The method of claim 9 , wherein the multiplexing the RRC message is based on allocating radio resources to one or more logical channels or data in a decreasing priority order determined by the logical channel prioritization order, wherein the one or more logical channels comprise the UL DCCH of the RRC message.

11 . An apparatus, comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform:

multiplexing, by a wireless device, a radio resource control, RRC, message in a medium access control protocol data unit, MAC PDU, wherein:

the RRC message indicates arrival of non-small data transmission, SDT, data; and

the multiplexing is based on a logical channel prioritization order indicating that the RRC message is higher priority than data of an SDT procedure; and

transmitting, by the wireless device, the MAC PDU.

12 . The apparatus of claim 11 , wherein the data of the SDT procedure is data of an uplink dedicated traffic channel, UL DTCH.

13 . The apparatus of claim 11 , wherein the logical channel prioritization order indicates that the RRC message is higher priority over a second RRC message of the data of the SDT procedure.

14 . The apparatus of claim 13 , wherein the second RRC message is associated with an uplink dedicated control channel, UL DCCH, for transmitting the RRC message.

15 . The apparatus of claim 11 , wherein the logical channel prioritization order indicates that the RRC message is:

higher priority than a cell radio network temporary identifier medium access control control element, C-RNTI MAC CE; or

equal priority to the C-RNTI MAC CE.

16 . The apparatus of claim 11 , wherein the logical channel prioritization order indicates that the RRC message is higher priority than one or more medium access control control element, MAC CEs, comprising at least one of:

a beam failure recovery (BFR) MAC CE;

a MAC CE for a buffer status report (BSR);

a power headroom report (PHR) MAC CE; and

a listen before talk (LBT) failure MAC CE.

17 . The apparatus of claim 11 , wherein the multiplexing and/or the transmitting is during the SDT procedure.

18 . The apparatus of claim 11 , wherein the wireless device determines to transmit, during the SDT procedure, the RRC message indicating arrival of non-SDT data.

19 . The apparatus of claim 11 , wherein the RRC message is for transmission via an uplink dedicated control channel, UL DCCH.

20 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to perform:

multiplexing, by a wireless device, a radio resource control, RRC, message in a medium access control protocol data unit, MAC PDU, wherein:

the RRC message indicates arrival of non-small data transmission, SDT, data; and

the multiplexing is based on a logical channel prioritization order indicating that the RRC message is higher priority than data of an SDT procedure; and

transmitting, by the wireless device, the MAC PDU.
