拡張マシンタイプ通信（ｅＭＴＣ）のためのＨＡＲＱおよび制御チャネルタイミング

Title:

拡張マシンタイプ通信（ｅＭＴＣ）のためのＨＡＲＱおよび制御チャネルタイミング

Document Type and Number:

Japanese Patent JP7332740

Kind Code:

B2

Abstract:

Aspects of the present disclosure provide hybrid automatic repeat request (HARQ) techniques for enhanced machine type communication (eMTC). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE) for determining a HARQ ID. The method generally includes determining a HARQ ID based, at least in part, on a coverage enhancement (CE) level, and performing a HARQ process timeline based, at least in part, on the determined HARQ ID. Another method is provided for determining a subframe to transmit feedback. The method generally includes determining at least one subframe to transmit a physical uplink control channel (PUCCH) to acknowledge one or more downlink transmissions based, at least in part, on availability of uplink subframes following one or more downlink subframes carrying the downlink transmissions to be acknowledged and transmitting the PUCCH in the determined at least one subframe.
