Abstract

A multi-radio device, such as User Equipment (UE), may experience coexistence issues among various ones of its constituent radio devices that operate at the same time. Various aspects of the disclosure provide techniques to mitigate coexistence issues in multi-radio devices, where significant in-device coexistence problems can exist. In particular, a method for coexistence of multi-radio devices is described. The method includes identifying, at an upper layer of a multi-radio UE, a type of incoming broadcast stream data. The method further includes determining a coexistence policy for operation of communication resources within the multi-radio UE based on the type of the incoming broadcast stream data. The method also includes arbitrating, at a lower layer of the multi-radio UE, between the communication resources based on the coexistence policy.

Claims

1. A method for wireless communications, comprising:

identifying, at an upper layer of a multi-radio user equipment (UE), a type of incoming broadcast stream data of a one-way communication only broadcast stream receiver;

determining a coexistence policy for operation of a broadband radio and the one-way communication only broadcast stream receiver within the multi-radio UE based on the identified type of the incoming broadcast stream data;

arbitrating, at a lower layer of the multi-radio UE, between communication resources based on the determined coexistence policy in which transmission by the broadband radio is prioritized over reception by the one-way communication only broadcast stream receiver; and

overriding the determined coexistence policy in which transmission by the broadband radio is prioritized when the identified type of the incoming broadcast stream data of the one-way communication only broadcast stream receiver is reference video frame data in which the reference video frame data is one of a predicted frame (P-frame) and an intra-frame (I-frame), and

wherein a non-reference frame data is a backward predicted frame (B-frame).

2. The method of claim 1 in which the determined coexistence policy comprises prioritizing transmission by the broadband radio over receiving parity data by the broadcast stream receiver.

3. The method of claim 1 in which the determined coexistence policy comprises prioritizing transmission by the broadband radio over receiving the non-reference video frame data by the broadcast stream receiver.

4. The method of claim 1 in which identifying the type of the incoming broadcast stream data further comprises identifying using at least one of a header in a broadcast channel which also broadcasts the incoming broadcast stream data, the header in an overhead application layer broadcast channel, and the header in a physical/media access control (PHY/MAC) layer broadcast channel.

5. The method of claim 4 in which the at least one of the header in the broadcast channel, the header in the overhead application layer broadcast channel, and the header in the PHY/MAC layer broadcast channel indicates whether the incoming broadcast stream data includes one of a broadcast audio signal, the reference video frame data, and the non-reference video frame data.

6. The method of claim 1, in which the upper layer is an application layer and the lower layer is a physical/media access control (PHY/MAC) layer.

7. The method of claim 1 in which overriding further comprises halting transmission of the broadband radio when the identified type of incoming broadcast stream data is one of audio data and the reference video frame data.

8. An apparatus configured for operation in a wireless communication network, the apparatus comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor being configured;

to identify, at an upper layer of a multi-radio user equipment (UE), a type of incoming broadcast stream data of a one-way communication only broadcast stream receiver;

to determine a coexistence policy for operation of a broadband radio and the one-way communication only broadcast stream receiver within the multi-radio UE based on the identified type of the incoming broadcast stream data;

to arbitrate, at a lower layer of the multi-radio UE, between communication resources based on the coexistence policy in which transmission by the broadband radio is prioritized over reception by the one-way communication only broadcast stream receiver; and

to override the determined coexistence policy in which transmission by the broadband radio is prioritized when the identified type of the incoming broadcast stream of the one-way communication only broadcast stream receiver is reference video frame data in which the reference video frame data is one of a predicted frame (P-frame) and an intra-frame (I-frame), and

wherein a non-reference frame data is a backward predicted frame (B-frame).

9. The apparatus of claim 8 in which the determined coexistence policy comprises prioritizing transmission by the broadband radio over receiving parity data by the broadcast stream receiver.

10. The apparatus of claim 8 in which the determined coexistence policy comprises prioritizing transmission by the broadband radio over receiving the non-reference video frame data by the broadcast stream receiver.

11. The apparatus of claim 8 in which the at least one processor is further configured to identify the type of the incoming broadcast stream data by identifying using at least one of a header in a broadcast channel which also broadcasts the incoming broadcast stream data, the header in an overhead application layer broadcast channel, and the header in a physical/media access control (PHY/MAC) layer broadcast channel.

12. The apparatus of claim 11 in which the at least one of the header in the broadcast channel, the header in the overhead application layer broadcast channel, and the header in the PHY/MAC layer broadcast channel indicates whether the incoming broadcast stream data includes one of a broadcast audio signal, the reference video frame data, and the non-reference video frame data.

13. The apparatus of claim 8, in which the upper layer is an application layer and the lower layer is a physical/media access control (PHY/MAC) layer.

14. The apparatus of claim 8 in which in which the at least one processor is further configured to override by halting transmission of the broadband radio when the identified type of incoming broadcast stream data is one of audio data and the reference video frame data.
