Implicitly releasing allocated resources
View Patent ↗A wireless network, such as an LTE (“Long-Term Evolution”) network, may be configured to receive an identifier from a wireless network. The identifier identifies a resource configuration in a plurality of resource configurations. The resource configuration corresponds to a plurality of resource attributes. At least one signal is transmitted to the wireless network using the plurality of resource attributes.
1. A method performed at a user equipment (UE), the method comprising:
receiving an allocation of a first resource from a network, the first resource available to the UE for transmission of control information to the network;
identifying a data transmission inactivity associated with the UE;
responsive to the identifying, implicitly releasing the first resource;
requesting a subsequent resource from the network; and
reusing the first resource for communication of control information to the network.
2. The method of claim 1 , wherein the first resource is an uplink resource.
3. The method of claim 1 , further comprising not using the first resource for communication after releasing or deactivating the first resource and before requesting the subsequent resource.
4. The method of claim 1 , further comprising identifying an expiry of time after requesting the subsequent resource during which a signal including an alternative to the first resource configuration is not received from the network.
5. The method of claim 1 , further comprising receiving from the network an indication that the first resource may be reused, in response to the request for the subsequent resource.
6. The method of claim 5 , wherein the indication received from the network includes a resource configuration identifier set to a predetermined value.
7. A user equipment (UE), comprising:
memory configured to store a predefined period of time; and
at least one processor configured to:
receive an allocation of a first resource from a network, the first resource available to the UE for transmission of control information to the network;
identify a data transmission inactivity associated with the UE;
responsive to the identify, implicitly release the first resource;
request a subsequent resource from the network; and
reuse the first resource for communication of control information to the network.
8. The user equipment of claim 7 , wherein the first resource is an uplink resource.
9. The user equipment of claim 7 , the at least one processor further configured to not use the first resource for communication after releasing or deactivating the first resource and before requesting the subsequent resource.
10. The user equipment of claim 7 , the at least one processor further configured to identify an expiry of time after requesting the subsequent resource during which a signal including an alternative to the first resource configuration is not received from the network.
11. The user equipment of claim 7 , the at least one processor further configured to receive from the network an indication that the first resource may be reused, in response to the request for the subsequent resource.
12. The user equipment of claim 11 , wherein the indication received from the network includes a resource configuration identifier set to a predetermined value.
13. A method performed by a wireless network, the method comprising:
allocating a first resource to a user equipment (UE), the first resource associated with communication of control information from the UE;
identifying a data transmission inactivity associated with the UE;
responsive to the identifying, de-allocating the first resource from the UE without transmitting explicit release signaling;
receiving a request for a subsequent resource from the UE; and
responsive to the request, indicating to the UE that the first resource may be reused.
14. The method of claim 13 , wherein the indicating comprises at least one of refraining from transmitting a signal to the user equipment including an alternative to the first resource configuration identifier, transmitting to the user equipment a resource configuration identifier set to a predetermined value, or wherein the first resource configuration defines is an uplink resource.
15. A wireless network configured to:
allocate a first resource to a user equipment (UE), the first resource associated with communication of control information from the UE;
identify a data transmission inactivity associated with the UE;
responsive to the identify, de-allocating the first resource from the UE without transmitting explicit release signaling;
receive a request for a subsequent resource from the UE; and
responsive to the request, indicate to the UE that the first resource may be reused.
16. The wireless network of claim 15 , further configured to perform the indication by refraing from transmitting a signal to the user equipment including an alternative to the first resource configuration identifier, further configured to perform the indication by transmitting to the user equipment a resource configuration identifier set to a predetermined value, or wherein the first resource is an uplink resource.
