Scheduling request process in a wireless device and wireless network
A wireless device receives one or more messages comprising configuration parameters for a logical channel in a plurality of logical channels. 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. The wireless device triggers a first scheduling request (SR) process for uplink transmissions requiring uplink resources of at least one first radio resource type. The wireless device receives an uplink grant indicating uplink radio resources. The wireless device cancels the first SR process if the uplink radio resources are of one of the at least one first radio resource type. Otherwise the wireless device maintains the first SR process pending. The wireless device transmits one or more transport blocks via the uplink radio resources.
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 first scheduling request (SR) process for uplink transmissions requiring uplink resources of at least one first radio resource type;
receiving, by the wireless device, an uplink grant indicating uplink radio resources;
canceling the first SR process if the uplink radio resources are of one of the at least one first radio resource type, otherwise maintaining the first SR process pending; and
transmitting, by the wireless device, one or more transport blocks via the uplink radio resources.
2. The method of claim 1 , wherein the uplink transmissions comprises one or more transport blocks.
3. The method of claim 1 , wherein the uplink transmissions comprises one or more media access control (MAC) control elements.
4. The method of claim 1 , wherein the one or more messages indicate that the uplink transmissions requires uplink resources of the at least one first radio resource type.
5. The method of claim 1 , wherein the one or more messages indicate a first mapping restriction of the uplink transmissions to uplink resources of the at least one first radio resource type.
6. The method of claim 1 , wherein the one or more transport blocks comprises the uplink transmissions if the uplink radio resources are of one of the at least one first radio resource type.
7. The method of claim 1 , further comprising, in response to triggering the first scheduling request (SR) process:
transmitting, by the wireless device, a SR signal; and
starting a first scheduling request prohibit timer.
8. The method of claim 1 , wherein the radio resource type indicates a cell type.
9. The method of claim 8 , wherein the cell type comprises at least one of the following:
a licensed cell type; and
an unlicensed cell type.
10. 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 first scheduling request (SR) process for uplink transmissions requiring uplink resources of at least one first radio resource type;
receive an uplink grant indicating uplink radio resources;
cancel the first SR process if the uplink radio resources are of one of the at least one first radio resource type, otherwise maintaining the first SR process pending; and
transmit one or more transport blocks via the uplink radio resources.
11. The wireless device of claim 10 , wherein the uplink transmissions comprises one or more transport blocks.
12. The wireless device of claim 10 , wherein the uplink transmissions comprises one or more media access control (MAC) control elements.
13. The wireless device of claim 10 , wherein the one or more messages indicate that the uplink transmissions requires uplink resources of the at least one first radio resource type.
14. The wireless device of claim 10 , wherein the one or more messages indicate a first mapping restriction of the uplink transmissions to uplink resources of the at least one first radio resource type.
15. The wireless device of claim 10 , wherein the one or more transport blocks comprises the uplink transmissions if the uplink radio resources are of one of the at least one first radio resource type.
16. The wireless device of claim 10 , wherein the instructions, when executed by the one or more processors, further cause the wireless device, in response to triggering the first scheduling request (SR) process, to:
transmit a SR signal; and
start a first scheduling request prohibit timer.
17. The wireless device of claim 10 , wherein the radio resource type indicates a cell type.
18. The wireless device of claim 17 , wherein the cell type comprises at least one of the following:
a licensed cell type; and
an unlicensed cell type.
