Uplink transmission in a wireless device and wireless network

1. A method comprising:

receiving, by a wireless device, one or more messages comprising configuration parameters for a logical channel in a plurality of logical channels, wherein the configuration parameters indicate a mapping restriction of the logical channel to one or more radio resource types in a plurality of radio resource types;

triggering a buffer status report (BSR) transmission when data becomes available for the logical channel with the mapping restriction and when a selected set of one or more logical channels with the same mapping restriction meet a first criteria;

receiving an uplink grant indicating radio resources of a first radio resource type;

constructing a transport block comprising the BSR;

transmitting, by the wireless device, the transport block via the radio resources of the first radio resource type.

2. The method of claim 1 , wherein the radio resource type indicates a cell type.

3. The method of claim 2 , wherein the cell type comprises at least one of the following:

a licensed cell type; and

an unlicensed cell type.

4. The method of claim 1 , wherein the mapping restriction is based, at least in part, on one or more quality of service (QoS) requirements of the logical channel.

5. The method of claim 4 , wherein a QoS requirement is based on a latency requirement of the logical channel.

6. The method of claim 1 , wherein the logical channel is configured with a priority and a prioritized bit rate (PBR).

7. The method of claim 1 , wherein the first criteria comprise: the selected set of one or more logical channels with the same mapping restriction do not include uplink buffer data.

8. The method of claim 1 , wherein the first criteria comprise:

the selected set of one or more logical channels with the same mapping restriction do not include uplink buffer data;

the logical channel has a higher priority than the selected set of one or more logical channels.

9. The method of claim 1 , wherein:

one or more first logical channels are mapped to one or more first radio resource type; and

one or more second logical channels are mapped to one or more second radio resource type.

10. The method of claim 9 , wherein:

a first buffer status report is triggered based on availability of data in at least one of one or more first logical channels, and independent of availability of data in the one or more second logical channels; and

a second buffer status report is triggered based on availability of data in at least one of one or more second logical channels, and independent of availability of data in the one or more first logical channels.

11. 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 one or more messages comprising configuration parameters for a logical channel in a plurality of logical channels, wherein the configuration parameters indicate a mapping restriction of the logical channel to one or more radio resource types in a plurality of radio resource types;

trigger a buffer status report (BSR) transmission when data becomes available for the logical channel with the mapping restriction and when a selected set of one or more logical channels with the same mapping restriction meet a first criteria;

receive an uplink grant indicating radio resources of a first radio resource type;

constructing a transport block comprising the BSR;

transmit the transport block via the radio resources of the first radio resource type.

12. The wireless device of claim 11 , wherein the radio resource type indicates a cell type.

13. The wireless device of claim 12 , wherein the cell type comprises at least one of the following:

a licensed cell type; and

an unlicensed cell type.

14. The wireless device of claim 11 , wherein the mapping restriction is based, at least in part, on one or more quality of service (QoS) requirements of the logical channel.

15. The wireless device of claim 14 , wherein a QoS requirement is based on a latency requirement of the logical channel.

16. The wireless device of claim 11 , wherein the logical channel is configured with a priority and a prioritized bit rate (PBR).

17. The wireless device of claim 11 , wherein the first criteria comprise: the selected set of one or more logical channels with the same mapping restriction do not include uplink buffer data.

18. The wireless device of claim 11 , wherein the first criteria comprise:

the selected set of one or more logical channels with the same mapping restriction do not include uplink buffer data;

the logical channel has a higher priority than the selected set of one or more logical channels.

19. The wireless device of claim 11 , wherein:

one or more first logical channels are mapped to one or more first radio resource type; and

one or more second logical channels are mapped to one or more second radio resource type.

20. The wireless device of claim 19 , wherein:

a first buffer status report is triggered based on availability of data in at least one of one or more first logical channels, and independent of availability of data in the one or more second logical channels; and

a second buffer status report is triggered based on availability of data in at least one of one or more second logical channels, and independent of availability of data in the one or more first logical channels.
