US 10,771,200 B2 · Method to decrease bluetooth power consumption for periodic traffic profiles

Abstract

Embodiments of a mobile device and method of communication are generally described herein. The mobile device may be configured to operate as a slave device for a Bluetooth link with a master device. The mobile device may transmit a packet in an ESCO interval. The mobile device may, in an ESCO retransmission slot of the ESCO interval: attempt to decode, from the slave device, a request for retransmission of the packet. If the request for retransmission is not successfully decoded, the mobile device may determine whether the request for retransmission was sent during the ESCO retransmission slot based at least partly on a channel energy level detected during the ESCO retransmission slot. If it is determined that the request for retransmission was not sent during the ESCO retransmission slot, the mobile device may refrain from monitoring subsequent ESCO retransmission slots of the ESCO interval. If it is determined that the request for retransmission was sent during the ESCO retransmission slot, the mobile device may monitor one or more of the subsequent ESCO retransmission slots of the ESCO interval.

Dependent claims

An apparatus of a mobile device, the mobile device configured to operate as a slave device for a Bluetooth link with a master device, the apparatus comprising:

memory;
and processing circuitry, wherein when the mobile device operates as the slave device, the processing circuitry is configured to:
encode a packet for transmission in a transmit enhanced synchronous connection-oriented (ESCO) slot of an ESCO interval;
in an ESCO retransmission slot of the ESCO interval:
attempt to decode, from the slave device, a request for retransmission of the packet;
if the request for retransmission is not successfully decoded, determine whether the request for retransmission was sent during the ESCO retransmission slot based at least on a channel energy level detected during the ESCO retransmission slot;
if it is determined that the request for retransmission was not sent during the ESCO retransmission slot, refrain from monitoring subsequent ESCO retransmission slots of the ESCO interval;
and
if it is determined that the request for retransmission was sent during the ESCO retransmission slot, monitor one or more of the subsequent ESCO retransmission slots of the ESCO interval for an additional request for retransmission of the packet.

6 more elements

A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a mobile device, the mobile device configured to operate as a slave device for a Bluetooth link with a master device, wherein when the mobile device operates as the slave device, the operations configure the processing circuitry to:

encode a packet for transmission in a transmit enhanced synchronous connection-oriented (ESCO) slot of an ESCO interval,
wherein the ESCO interval includes the transmit ESCO slot, a receive ESCO slot, and a first plurality of ESCO retransmission slots;
in a second plurality of ESCO retransmission slots included in the first plurality of ESCO retransmission slots:
attempt to decode, from the slave device, at least one request for retransmission of the packet;
and
determine per-slot channel energy levels;
if at least one request for retransmission is not successfully decoded in the second plurality of ESCO retransmission slots and if the per-slot channel energy levels are less than a threshold:
refrain from monitoring the remaining ESCO retransmission slots of the first plurality of ESCO retransmission slots;
and
refrain from retransmission of the packet.
