Abstract

Disclosed are apparatuses, methods and computer program instructions which receive or detect an in-device coexistence interference condition change in a user equipment equipped with a plurality of transceivers, send an indication of the in-device coexistence interference condition change to an access point and receive a media access control element configured for muting/unmuting at least one of a plurality of transceivers from the access point. The condition of in-device coexistence interference relates to interference among transceivers such as a long term evolution advanced transceiver and a Bluetooth transceiver in the same user equipment. The media access control element can be configured to either promote a measurement gap pause or short discontinuous transmission during a condition of in-device coexistence interference.

First claim

What is claimed is:

1. An apparatus, comprising:
circuitry configured to
receive or detect a first in-device coexistence interference condition change in a user equipment equipped with a plurality of transceivers;
control sending an indication of the first in-device coexistence interference condition change to an access point;
control receiving a first media access control element configured for muting at least one of the transceivers;
receive or detect a second in-device coexistence interference condition change;
send an indication of the second in-device coexistence interference condition change to the access point;
receive a second media access control element configured for unmuting at least one of the muted transceivers; and
unmute the at least one of the muted transceivers based on the received second media access control element.

2. The apparatus of claim 1 , wherein the condition of in-device coexistence interference relates to interference among a cellular transceiver and a Bluetooth transceiver in the same user equipment.

3. The apparatus of claim 2 , wherein the cellular transceiver is a long term evolution transceiver, a long term evolution advanced transceiver, a wideband code division multiple access transceiver, or a high speed packet access transceiver.

4. The apparatus of claim 1 , wherein the first media access control element is configured to promote short discontinuous transmission during a condition of in-device coexistence interference.

5. The apparatus of claim 4 , wherein short discontinuous transmission during in-device coexistence interference is allocated a logical channel identity and index bits associated with a pause and start configuration pattern for short discontinuous transmission.

6. The apparatus of claim 5 , wherein the index bits indicate a pause and. stop pattern attributable to a time division duplex configuration, a. Bluetooth master or slave type, or network schedule.

7. The apparatus of claim 6 , wherein a short discontinuous transmission timer is not employed.

8. The apparatus of claim 1 , wherein the first media access control element is configured to promo e a measurement gap pause during a condition of in-device coexistence interference.

9. The apparatus of claim 8 , wherein the measurement gap pause during in-device coexistence interference is allocated a logical channel identity, and index bits associated with a pause and start of configuration measurement gap pattern.

10. The apparatus of claim 9 , wherein index bits indicate a pause and start measurement gap pattern attributable to a time division duplex configuration, Bluetooth master or slave type, or network schedule.

11. The apparatus of claim 1 , wherein at least one of the first in-device coexistence interference change condition or the second in-device coexistence interference change condition is received from a coexistence information and discovery server.

12. An apparatus comprising:
circuitry configured to
receive or detect an in-device coexistence interference condition change in a user equipment equipped with a plurality of transceivers;
send an indication of the in-device coexistence interference condition change to an access point; and
receive a media access control element configured for muting at least one of the transceivers, wherein

the condition of in-device coexistence interference relates to interference among a cellular transceiver and a Bluetooth transceiver in the user equipment, and
the condition of in-device coexistence interference from the Bluetooth transceiver comprises at least one of:
on-going interference from a Bluetooth transceiver where the interference is detected based upon information contained in a sniff request or a synchronous connection oriented (SCO) link request; or
potential interference detected based upon statistical analysis of the information contained in a sniff request or a SCO link request.

13. A method comprising:
receiving or detecting a first in-device coexistence interference condition change in a user equipment equipped with at least a plurality of transceivers;
sending an indication of the first in-device coexistence interference condition change to an access point;
receiving a first media access control element configured for muting at least one of the transceivers;
receiving or detecting a second in-device coexistence interference condition change;
sending an indication of the second in-device coexistence interference condition change to the access point; and
receiving a second media access control element configured for unmuting at least one of the muted transceivers; and
unmuting the at least one of the muted transceivers based on the received second media access control element.

14. An apparatus comprising:
circuitry configured to
receive a first indication of in-device coexistence interference condition change from a user equipment equipped with a plurality of transceivers;
send a first media access control clement configured for muting at least one of the plurality of transceivers in the user equipment;
receive a second indication of in-device coexistence interference condition change from the user equipment; and
send a second media access control element configured for unmuting at least one of the muted transceivers.

15. The apparatus of claim 14 , wherein the first media access control element is configured to promote short discontinuous transmission during a condition of in-device coexistence interference.

16. The apparatus of claim 15 , wherein the first media access control element is configured to indicate one or more patterns based upon a time division duplex configuration, a Bluetooth node type, or due to a scheduling restriction in a cellular network.

17. The apparatus of claim 14 , wherein the first media access control element is configured to promote a measurement gap pause during a condition of in-device coexistence interference.
