Co-existence for co-located radios which operate in the same frequency band

A method comprising:

• setting a priority level of a slot based on a determination of a likelihood that the slot will be required by a first radio;
• and
• signaling the priority level to a second radio, wherein the first and second radios are co-located and share a resource;
• wherein setting a priority level of slot based on a determination of a likelihood that the slot will be required by a first radio comprises:
• determining a likelihood that the slot will be required by the first radio;
• and
• setting a priority level based on the likelihood:
• wherein the slot comprises a sniff anchor point and wherein determining a likelihood that the slot will be required by the first radio comprises:
• determining a likelihood that a peer of the first radio will be active at the sniff anchor point;
• wherein the determination of a likelihood that a peer of the first radio will be active at the sniff anchor point is based on at least a sniff subrate used by the peer.

An apparatus comprising a radio, the radio comprising:

• a prediction module arranged to set a priority level of a slot based on a determination of a likelihood that the slot will be required by the radio;
• and
• an output to a signaling link arranged to signal the priority level to a co-located radio, wherein the radio and the co-located radio share a resource;
• wherein the slot comprises a re-transmission slot, the radio further comprises a classifier and wherein the prediction module is arranged to use an output from the classifier to determine the likelihood that the re-transmission slot will be required by the radio.

One or more tangible non-transitory processor-readable media with processor-executable instructions for performing a method comprising:

• setting a priority level of a slot based on a determination of a likelihood that the slot will be required by a first radio;
• and signaling the priority level to a second radio, wherein the first and second radios are co-located and share a resource, wherein setting a priority level of slot based on a determination of a likelihood that the slot will be required by a first radio comprises:
• determining a likelihood that the slot will be required by the first radio;
• and setting a priority level based on the likelihood;
• wherein the slot comprises a re-transmission slot and wherein determining a likelihood that the slot will be required by the first radio comprises:
• computing a metric, the metric comprising one of a number of re-transmission slots used in a defined period and a number of failures in a primary transmission slot.

A method comprising:

• setting a priority level of a slot based on a determination of a likelihood that the slot will be required by a first radio;
• and
• signaling the priority level to a second radio, wherein the first and second radios are co-located and share a resource;
• wherein the slot comprises a re-transmission slot and wherein the likelihood is determined based on an output from a classifier associated with the first radio, and wherein determining the likelihood that the slot will be required by the first radio includes:
• computing a metric, the metric comprising one of a number of re-transmission slots used in a defined period and a number of failures in a primary transmission slot.

A method comprising:

• setting a priority level of a slot based on a determination of a likelihood that the slot will be required by a first radio;
• and signaling the priority level to a second radio, wherein the first and second radios are co-located and share a resource;
• wherein the slot comprises a re-transmission slot and wherein the likelihood is determined based on an output from a classifier associated with the first radio, wherein setting the priority level comprises:
• if the output from the classifier indicates that a channel used for a primary transmission slot is poor, setting a high priority level;
• and if the output from the classifier indicates that a channel used for a primary transmission slot is good, setting a low priority level, wherein the first radio comprises the classifier and a prediction module, and wherein the prediction module is arranged to use the output from the classifier to determine the likelihood that the re-transmission slot will be required by the first radio.
