Abstract
Aspects of the disclosure relate to use of aggregated signal transmission. An aggregated signal may comprise multiple packets, reception of which may be acknowledged via a block acknowledgment. A packet may be repeated in successive aggregated signal transmissions, with a maximum quantity of repetitions being based on a packet class associated with a packet. Repetition of a packet may be based on receiving a negative acknowledgment indicating failed packet reception and/or decoding. A frequency hopping protocol may be used for the successive aggregated signal transmissions.
Claims21
A method comprising:
- sending, in a first aggregated signal and via a first frequency channel, at least a first packet and a second packet;
- receiving a block acknowledgment indicating successful reception of the first packet and unsuccessful reception of the second packet;
- and
- based on the block acknowledgment indicating unsuccessful reception of the second packet, sending, in a second aggregated signal and via a second frequency channel, one or more new audio packets and a repetition of the second packet.
A method comprising:
- sending, in a first aggregated signal, at least a first packet and a second packet;
- receiving a block acknowledgment indicating successful reception of the first packet and unsuccessful reception of the second packet;
- and
- based on the block acknowledgment indicating unsuccessful reception of the second packet and based on a quantity of repetitions of the second packet being less than a threshold, sending, in one or more second aggregated signals, one or more new audio packets and one or more repetitions of the second packet;
- wherein, based on the block acknowledgment indicating successful reception of the first packet, the one or more second aggregated signals exclude repetitions of the first packet.
A method comprising:
- receiving, in a first aggregated signal, at least a first packet and a second packet;
- sending a block acknowledgment indicating successful reception of the first packet and unsuccessful reception of the second packet;
- and
- receiving, in one or more second aggregated signals, one or more new audio packets and one or more repetitions of the second packet, wherein the one or more second aggregated signals do not comprise repetitions of the first packet.
