Embodiment Construction

[0053] First, the terms "system" and "network" in this article are often used interchangeably in this article. , The character " / " in this article generally means that the associated objects before and after are in an "or" relationship. The term "and / or" in this text is only an association relationship that describes the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations.

[0054] In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally also includes Other steps or units inherent in these processes, methods, products or equipment.

Abstract

The present application discloses a data transmission method and device and relates to the technical field of communication to improve the multiplexing flexibility of a HARQ unit. The method includesthat a terminal device receives the configuration information sent by a network-side device, wherein the configuration information includes the information of a first hybrid automatic repeat request (HARQ) unit, the information of the first HARQ unit is configured to instruct the data of N types of services of the terminal device controlled by the first HARQ unit to be transmitted on a wireless resource having at least two physical characteristics, N is an integer greater than or equal to 1, and the first HARQ unit is a HARQ entity and / or a HARQ process; and the terminal device transmits the data of the N types of services according to the configuration information.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to a data transmission method and device. Background technique [0002] In the field of communication technology, hybrid automatic repeat request (Hybrid Automatic RepeatreQuest, HARQ) technology can be used to improve signal transmission quality and ensure information reliability. In the HARQ technology, the base station allocates a HARQ sequence number to the UE according to the service requirements of the user equipment (User Equipment, UE), and the UE determines the HARQ unit (including the HARQ entity and / or HARQ process) for controlling data transmission according to the HARQ sequence number. Among them, one HARQ unit represents a kind of HARQ rule, including rules such as the sending time of receiving and / or sending data, the feedback time of receiving and / or sending feedback information, and the retransmission time of receiving and / or sending retransmitted data. Th...
