Buffer status report transmission in a wireless device
A wireless device receives configuration parameters from a base station. The configuration parameters are for a logical channel of logical channels for data transmission to the base station. The configuration parameters indicate a mapping restriction of the logical channel to one or more radio resource types. The wireless device transmits a buffer status report to the base station based on: data becoming available for the logical channel with the mapping restriction; and a selected set of one or more logical channels, of the logical channels, with the same mapping restriction meeting a first criteria.
1. A method comprising:
receiving, by a wireless device from a base station, configuration parameters for a logical channel of logical channels for data transmission to the base station, wherein the configuration parameters indicate a mapping restriction of the logical channel to one or more radio resource types; and
transmitting, by the wireless device to the base station, a buffer status report based on:
data becoming available for the logical channel with the mapping restriction; and
a selected set of one or more logical channels, of the logical channels, with the same mapping restriction meeting a first criteria.
2. The method of claim 1 , wherein the one or more radio resource types indicate 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, of the one or more QoS requirements, 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.
7. The method of claim 1 , wherein the first criteria comprises the selected set of one or more logical channels, of the logical channels, with the same mapping restriction not comprising uplink buffer data.
8. The method of claim 1 , wherein the first criteria comprises
the logical channel having 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, of the logical channels, are mapped to one or more first radio resource types; and
one or more second logical channels, of the logical channels, are mapped to one or more second radio resource types.
10. The method of claim 9 , wherein:
a first buffer status report is triggered based on availability of data in at least one of the 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, from a base station, configuration parameters for a logical channel of logical channels for data transmission to the base station, wherein the configuration parameters indicate a mapping restriction of the logical channel to one or more radio resource types;
transmit, to the base station, a buffer status report based on:
data becoming available for the logical channel with the mapping restriction; and
a selected set of one or more logical channels, of the logical channels, with the same mapping restriction meeting a first criteria.
12. The wireless device of claim 11 , wherein the one or more radio resource types indicate 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, of the one or more QoS requirements, 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.
17. The wireless device of claim 11 , wherein the first criteria comprises the selected set of one or more logical channels, of the logical channels, with the same mapping restriction not comprising uplink buffer data.
18. The wireless device of claim 11 , wherein the first criteria comprises
the logical channel having 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, of the logical channels, are mapped to one or more first radio resource types; and
one or more second logical channels, of the logical channels, are mapped to one or more second radio resource types.
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 the 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.
