User equipment using hybrid automatic repeat request

摘要

A user equipment comprises a transmitter and an adaptive modulation and coding controller. The transmitter is configured to transmit data over an air interface in a single transmission time interval with a first specified modulation and coding scheme, where the single transmission time interval has a plurality of transport block sets. In response to receiving a repeat request for retransmission of at least one particular transport block set, the transmitter retransmits the at least one of the particular transport block sets. The adaptive modulation and coding controller is configured to change the specified modulation and coding scheme to a second specified modulation and coding scheme, enabling a combining of a particular transport block set transmitted at the first specified modulation and coding scheme with a retransmitted version of the particular transport block set transmitted at the second specified modulation and coding scheme.

主权项

1. A user equipment (UE), comprising:
a transmitter to transmit an uplink (UL) message over a third generation partnership project (3GPP) network according to an adaptive data transmission parameter, the UL message including a plurality of transport block (TB) sets in a first transmission time interval (TTI); and a processor to selectively change the adaptive data transmission parameter based on a UL channel condition, wherein the transmitter is configured to retransmit, in a second TTI, a first TB of the plurality of TB sets according to the changed adaptive transmission parameter.
