Receiving data without monitoring control channel
A method, user equipment (UE) and integrated circuit for receiving data transmitted over a wireless network. The method includes executing an application that receives data from the network, transmitting UE assistance information to the network, wherein the UE assistance information corresponds to a traffic pattern for the data that is received from the network for the application, entering a radio resource control (RRC) inactive state and receiving the data from the network while in the RRC inactive state.
1. A method, comprising:
at a user equipment (UE) that is connected to a network:
executing an application that receives data from the network;
transmitting UE assistance information to the network, wherein the UE assistance information corresponds to a traffic pattern for the data that is received from the network for the application;
entering a radio resource control (RRC) inactive state; and
receiving the data from the network while in the RRC inactive state without monitoring a physical downlink control channel (PDCCH).
2. The method of claim 1 , wherein the UE assistance information is transmitted in a Random Access Channel (RACH) request.
3. The method of claim 1 , wherein the UE assistance information is transmitted when the UE is in an RRC connected state with the network.
4. The method of claim 1 , wherein the UE assistance information comprises one of a minimum grant size, a minimum grant frequency and a minimum grant duration.
5. The method of claim 1 , further comprising:
determining the traffic pattern associated with the application.
6. The method of claim 1 , wherein the application is a streaming application.
7. The method of claim 1 , further comprising:
executing a second application; and
aligning incoming data transmissions for the second application with the receipt of the data for the application when the UE is in the RRC inactive state.
8. The method of claim 1 , further comprising:
determining that the UE is out of synchronization with the network;
starting a timer when the UE is out of synchronization with the network, wherein the UE remains in an RRC connected state during a length of the timer;
monitoring a control channel during the length of the timer for downlink data transmissions from the network; and
transitioning to the RRC inactive state when the timer expires.
9. A user equipment (UE), comprising:
a transceiver configured to communicate with a network; and
a processor configured to perform operations, the operations comprising:
executing an application that receives data from the network;
transmitting UE assistance information to the network, wherein the UE assistance information corresponds to a traffic pattern for the data that is received from the network for the application;
entering a radio resource control (RRC) inactive state; and
receiving the data from the network while in the RRC inactive state without monitoring a physical downlink control channel (PDCCH).
10. The UE of claim 9 , wherein the UE assistance information is transmitted in a Random Access Channel (RACH) request.
11. The UE of claim 9 , wherein the UE assistance information is transmitted when the UE is in an RRC connected state with the network.
12. The UE of claim 9 , wherein the UE assistance information comprises one of a minimum grant size, a minimum grant frequency and a minimum grant duration.
13. The UE of claim 9 , wherein the operations further comprise:
determining the traffic pattern associated with the application.
14. The UE of claim 9 , wherein the processor comprises an application processor and a baseband processor, wherein the application processor executes the application.
15. The UE of claim 9 , wherein the operations further comprise:
executing a second application; and
aligning incoming data transmissions for the second application with the receipt of the data for the application when the UE is in the RRC inactive state.
16. The UE of claim 9 , wherein the operations further comprise:
determining that the UE is out of synchronization with the network;
starting a timer when the UE is out of synchronization with the network, wherein the UE remains in an RRC connected state during a length of the timer;
monitoring a control channel during the length of the timer for downlink data transmissions from the network; and
transitioning to the RRC inactive state when the timer expires.
17. An integrated circuit, comprising:
circuitry configured to transmit UE assistance information to a network, wherein the UE assistance information corresponds to a traffic pattern for data that is received from the network for an application;
circuitry configured to enter a radio resource control (RRC) inactive state; and
circuitry configured to receive the data from the network while in the RRC inactive state without monitoring a physical downlink control channel (PDCCH).
18. The integrated circuit of claim 17 , wherein the UE assistance information is transmitted in a Random Access Channel (RACH) request.
19. The integrated circuit of claim 17 , wherein the UE assistance information is transmitted during an RRC connected state with the network.
20. The integrated circuit of claim 17 , wherein the UE assistance information comprises one of a minimum grant size, a minimum grant frequency and a minimum grant duration.
