Problems solved by technology

[0004] However, in the existing Multi-RAT coordination technology, the processing delay for data packets is very long, which cannot meet the needs of services, especially for some services with relatively high delay requirements.

Embodiment Construction

[0084] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention. It should be noted that, in the case of no conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.

[0085] Taking Multi-RAT coordination between UMTS and LTE as an example, the protocol stacks of the network equipment of the two existing standards (UMTS and LTE) are complete and independent. For example, the anchor point is based on the Internet Protocol (Internet Protocol, IP ) packets for distribution. Wherein, the anchor point is used to perform joint radio resource management on radio resources of at least two standards. The anchor point can be an independent network element, or it can be set inside a network element such as a base station or an RNC as a logical function node. In this joint radio resource management mode, a network device ...

Abstract

The invention provides a data sending method. The method comprises the steps that a medium access control (MAC) entity of a first network node allocates data packets to at least one hybrid automatic repeat request (HARQ) unit of at least two cells, wherein different radio access technologies (RATs) are employed by the at least two cells, the at least two cells share the same HARQ unit, or each of the at least two cells corresponds to one HARQ unit, and the HARQ unit is an HARQ entity and / or an HARQ process; and the first network node sends the data packets to a second network node through the at least two cells. Through application of the scheme, the data packets are allocated to at least one HARQ unit of the at least two cells by a shared MAC layer, so the end-to-end time delay is effectively reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a data sending method, a data receiving method and a device. Background technique [0002] Multi-radio network standard coordination, also known as multi-radio access technology coordination (Multi-RAT coordination) technology, the main function of the technology is joint radio resource management (joint radio resource) between networks of different radio access technologies. management). In the following, multi-radio network standard cooperation is equivalent to Multi-RAT coordination. The radio access technology (RAT) that can be applied to this technology may include Universal Mobile Telecommunications System (UMTS), Global System for Mobile Communications (GSM), Code Division Multiple Code Division Multiple Access (CDMA), wireless local area network (wireless local area network, WLAN), wireless fidelity (Wireless Fidelity, Wifi), long-term evolution (Long Term ...
