Abstract

An apparatus configured to establish a first radio link for short range communications using a first protocol and a second radio link for short range communications using a second protocol, wherein the first and second radio links share an antenna, process traffic load information for the first radio link, the information being dependent on configuration parameters for the first radio link, determine, based on the information, time domain resources available for second data traffic on the second radio link, based on the time domain resources available for the second data traffic on the second radio link, determine a fragmentation size for packets sent on the second radio link and generate transmissions to exchange the second data traffic in the time domain resources available for the second data traffic on the second radio link in fragmented packets according to the determined fragmentation size.

First claim

What is claimed:

1 . An apparatus comprising processing circuitry configured to:
establish a first radio link for short range communications using a first protocol and a second radio link for short range communications using a second protocol, wherein the first and second radio links share an antenna; process traffic load information for the first radio link, the information being dependent on configuration parameters for the first radio link; determine, based on the information, time domain resources available for second data traffic on the second radio link; based on the time domain resources available for the second data traffic on the second radio link, determine a fragmentation size for packets sent on the second radio link; and generate transmissions to exchange the second data traffic in the time domain resources available for the second data traffic on the second radio link in fragmented packets according to the determined fragmentation size.

2 . The apparatus of claim 1 , wherein the processing circuitry executes a first module related to the first radio link and a second module related to the second radio link, and wherein the information related to a transmission and reception pattern for first data traffic on the first radio link is received by the second module from the first module.

3 . The apparatus of claim 2 , wherein the second module receives updated traffic load information for the first radio link and based on the updated traffic load information, adapts the fragmentation size for packets sent on the second radio link.

4 . The apparatus of claim 2 , wherein, when the time domain resources available for the second data traffic on the second radio link does not comprise contiguous time domain resources sufficient to support a minimum packet size on the second radio link, the second data traffic is not exchanged until updated traffic load information for the first radio link is received and the updated traffic load information indicates updated time domain resources available for the second data traffic on the second radio link comprise contiguous time domain resources sufficient to support a minimum packet size on the second radio link.

5 . The apparatus of claim 2 , wherein the fragmentation size depends on the configuration parameters for the first radio link including a type of the first radio link.

6 . The apparatus of claim 5 , wherein the first radio link is a Bluetooth link and the type of the Bluetooth link comprises one of a synchronous connection-oriented (SCO) Bluetooth link, an enhanced synchronous connection-oriented (eSCO) Bluetooth link, a first audio Bluetooth link for one hearing aid, or a second audio Bluetooth link for two hearing aids.

7 . The apparatus of claim 6 , wherein the transmission and reception pattern for the first data traffic is dependent on a number of retransmissions configured for the Bluetooth link, wherein the number of retransmissions configured for the SCO Bluetooth link is 0 or 1, the number of retransmissions configured for the eSCO Bluetooth link is 0, 1, 2 or 3, the number of retransmissions configured for the first audio Bluetooth link is 0 or 1, and the number of retransmissions configured for the second audio Bluetooth link is 0 or 1.

8 . The apparatus of claim 7 , wherein the second radio link is a Thread link.

9 . The apparatus of claim 8 , wherein the Bluetooth link has a higher priority than the Thread link.

10 . The apparatus of claim 8 , wherein the Bluetooth link has a higher priority than the Thread link when Thread operations comprise a first state and the Thread link has a higher priority than the Bluetooth link when Thread operations comprise a second state.

11 . The apparatus of claim 10 , wherein the first state comprises wakeup operations or command execution operations for a Thread device and the second state comprises connection operations for the Thread device.

12 . The apparatus of claim 10 , wherein, when the Thread state changes, the second module adapts a priority for the second link relative to the first link.

13 . An apparatus comprising processing circuitry configured to:
establish a radio link for short range communications using a wireless protocol; process data traffic on the radio link from a source device, the data traffic transmitted by the source device in a transmission pattern with a fragmentation size; detect the fragmentation size and the transmission pattern; and generate, for transmission on the radio link to the source device, transmissions in accordance with the detected fragmentation size and the transmission pattern.

14 . The apparatus of claim 13 , wherein the wireless protocol is Thread.

15 . A method, comprising:
establishing a first radio link for short range communications using a first protocol and a second radio link for short range communications using a second protocol, wherein the first and second radio links share an antenna; processing traffic load information for the first radio link, the information being dependent on configuration parameters for the first radio link; determining, based on the information, time domain resources available for second data traffic on the second radio link; based on the time domain resources available for the second data traffic on the second radio link, determining a fragmentation size for packets sent on the second radio link; and generating transmissions to exchange the second data traffic in the time domain resources available for the second data traffic on the second radio link in fragmented packets according to the determined fragmentation size.

16 . The method of claim 15 , wherein a first module is related to the first radio link and a second module is related to the second radio link, and wherein the information related to a transmission and reception pattern for first data traffic on the first radio link is received by the second module from the first module.

18 . The method of claim 16 , wherein, when the time domain resources available for the second data traffic on the second radio link does not comprise contiguous time domain resources sufficient to support a minimum packet size on the second radio link, the second data traffic is not exchanged until updated traffic load information for the first radio link is received and the updated traffic load information indicates updated time domain resources available for the second data traffic on the second radio link comprise contiguous time domain resources sufficient to support a minimum packet size on the second radio link.

19 . The method of claim 16 , wherein the fragmentation size depends on the configuration parameters for the first radio link including a type of the first radio link.

20 . The method of claim 19 , wherein the first radio link is a Bluetooth link and the type of the Bluetooth link comprises one of a synchronous connection-oriented (SCO) Bluetooth link, an enhanced synchronous connection-oriented (eSCO) Bluetooth link, a first audio Bluetooth link for one hearing aid, or a second audio Bluetooth link for two hearing aids.
