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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the sending the repetition of the second packet comprises sending one or more repetitions of the second packet in one or more aggregated signals. ### Claim 3 (depends on 2) The method of claim 2, wherein a quantity of the one or more repetitions of the second packet is based on a packet class associated with the second packet. ### Claim 4 (depends on 2) The method of claim 2, wherein the sending the one or more repetitions of the second packet comprises sending the one or more repetitions of the second packet until a block acknowledgment indicating successful reception of the second packet is received. ### Claim 5 (depends on 1) The method of claim 1, wherein the second aggregated signal excludes, based on the block acknowledgment indicating successful reception of the first packet, a repetition of the first packet. ### Claim 6 (depends on 1) The method of claim 1, wherein the first frequency channel and the second frequency channel are based on a frequency hopping pattern. ### Claim 7 (depends on 1) The method of claim 1, wherein the first packet or the second packet comprise at least one of: an audio packet or a control packet. ### Claim 8 (depends on 1) The method of claim 1, wherein sending the second aggregated signal comprising one or more new audio packets comprises maintaining a same quantity of audio packets in the second aggregated signal as in the first aggregated signal. ### Claim 9 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. ### Claim 10 (depends on 9) The method of claim 9, further comprising: sending, using a frequency hopping protocol, the first aggregated signal and the one or more second aggregated signals. ### Claim 11 (depends on 9) The method of claim 9, wherein the threshold is based on a packet class associated with the second packet. ### Claim 12 (depends on 9) The method of claim 9, further comprising: ceasing sending repetitions of the second packet based on at least one of: the quantity of repetitions of the second packet being equal to the threshold; or receiving a second block acknowledgment indicating successful reception of the second packet. ### Claim 13 (depends on 9) The method of claim 9, further comprising: sending the first aggregated signal via a first subframe; and sending the one or more second aggregated signals via one or more second subframes different from the first subframe. ### Claim 14 (depends on 13) The method of claim 13, wherein the first subframe comprises a plurality of aggregated signals, wherein the method further comprises: sending, to a respective device, a respective aggregated signal of the plurality of aggregated signals. ### Claim 15 (depends on 9) The method of claim 9, further comprising: sending the first aggregated signal or the one or more second aggregated signals via one or more of an industrial, scientific, and medical (ISM) band, a very high frequency (VHF) band, or an ultra-high frequency (UHF) band. ### Claim 16 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. ### Claim 17 (depends on 16) The method of claim 16, further comprising receiving, based on a frequency hopping protocol, the first aggregated signal and the one or more second aggregated signals. ### Claim 18 (depends on 16) The method of claim 16, wherein a quantity of the one or more repetitions is based on a packet class associated with the second packet. ### Claim 19 (depends on 16) The method of claim 16, further comprising: receiving the first aggregated signal via a first subframe; and receiving the one or more second aggregated signals via one or more second subframes different from the first subframe. ### Claim 20 (depends on 19) The method of claim 19, wherein the first subframe comprises a plurality of aggregated signals from a plurality of devices. ### Claim 21 (depends on 16) The method of claim 16, further comprising: receiving the first aggregated signal or the one or more second aggregated signals via one or more of an industrial, scientific, and medical (ISM) band, a very high frequency (VHF) band, or an ultra-high frequency (UHF) band.
