EVOLVED NODE-B, USER EQUIPMENT, AND METHODS FOR HYBRID AUTOMATIC REPEAT REQUEST (HARQ) COMMUNICATION

摘要

Embodiments of an Evolved Node-B (eNB) and methods for HARQ transmission are disclosed herein. The eNB may transmit, to a reduced-latency User Equipment (UE), an initial HARQ block and a diversity HARQ block for a reduced-latency data block. A sub-frame spacing between the transmissions of the HARQ blocks may be less than a sub-frame spacing used for transmissions of HARQ blocks to UEs not operating as reduced-latency UEs. The HARQ blocks for the reduced-latency data block may be transmitted in a reduced-latency region of time and frequency resources reserved for HARQ processes with reduced-latency UEs. In addition, HARQ blocks may be transmitted in time and frequency resources exclusive of the reduced-latency region to other UEs not operating as reduced-latency UEs.

1. An Evolved Node-B (eNB) comprising hardware processing circuitry including transceiver circuitry configured to:
as part of a Hybrid Automatic Repeat Request (HARQ) process with a first User Equipment (UE):
transmit an initial HARQ block for a first data block; andtransmit a diversity HARQ block for the first data block such that the transmissions of the HARQ blocks for the first data block occur during sub-frames that are spaced apart in time by a predetermined HARQ interval; as part of a HARQ process with a reduced-latency UE:
transmit an initial HARQ block for a reduced-latency data block; andtransmit a diversity HARQ block for the reduced-latency data block such that the transmissions of the HARQ blocks for the reduced-latency data block occur during sub-frames that are spaced apart in time by a predetermined reduced-latency HARQ interval that is less than the HARQ interval.
