Abstract
There is provided a system and method for dynamically adjusting the maximum number of hybrid ARQ transmissions in a wireless system. More specifically, in one embodiment, there is provided a method comprising generating a plurality of hybrid ARQ sub-packets associated with a packet, wherein a transmitter is configured to transmit up to a maximum number of the hybrid ARQ sub-packets, detecting a degradation in transmission quality that affects the transmitter, and reducing the maximum number of hybrid ARQ sub-packets associated with the packet that can be transmitted by the transmitter in response to detecting the degradation.
Claims22
A method comprising:
- generating a plurality of hybrid ARQ sub-packets associated with a packet, wherein a transmitter is configured to transmit up to a maximum number of the hybrid ARQ sub-packets;
- detecting a degradation in transmission quality;
- and
- in response to detecting the degradation, reducing the maximum number of hybrid ARQ sub-packets associated with the packet that can be transmitted by the transmitter.
A method comprising:
- detecting a degradation in transmission quality;
- receiving a sub-packet transmission from a transmitter, wherein the sub-packet is one of a plurality of sub-packets associated with a packet;
- and
- sending an acknowledgement to the transmitter if at least a predetermined number of sub-packets associated with the packet have been received, wherein the acknowledgement is sent regardless of whether the packet was successfully decoded.
A hybrid ARQ enabled device configured to:
- generate a plurality of hybrid ARQ sub-packets associated with a packet, wherein a transmitter is configured to transmit up to a maximum number of the hybrid ARQ sub-packets;
- detect a degradation in transmission quality that affects the transmitter;
- and
- reduce the maximum number of hybrid ARQ sub-packets associated with the packet that can be transmitted by the transmitter in response to detecting the degradation.
A method comprising:
- detecting a degradation in transmission quality;
- and
- adjusting a resource allocation priority of acknowledgement/non-acknowledgement feedback from a receiver in response to detecting the degradation.
