Problems solved by technology

For other resource blocks transmitted by LTE in the same subframe, there is no similar requirement, which will cause a huge waste of PHICH capacity
Therefore, the ACK indication method of the traditional PHICH corresponding to the resource position is difficult to apply to the MUSA-based multi-user access technology

Embodiment Construction

[0069] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0070] The embodiment of the present invention designs a new data confirmation indication mode, which fully supports the simultaneous access capability of a large number of users brought by MUSA. To this end, in the embodiment of the present invention, firstly, each UE is assigned a MUSA number that is unique in a cell or in a certain area. Optionally, the user can select a certain or a certain group of MUSA spreading sequences to transmit the MUSA data packet according to the assigned MUSA number. When the base station correctly receives the MUSA data packet of a certain...

Abstract

The invention discloses a retransmission control method and device for a multiple user shared access process, and user equipment. The method comprises the steps of distributing MUSA (Multiple User Shared Access) numbers to the UE (User Equipment); receiving MUSA data packets sent by the UE in an uplink MUSA resource range which is indicated by the base station; indicating a segment of wireless resource block for transmitting acknowledgment messages by employing an MUSA-RNTI (MUSA-Radio Network Temporary Identity); and broadcasting the MUSA numbers of the UE of which data packets are correctly received in the indicated wireless resource block, thereby enabling the UE to determine whether to retransmit the sent MUSA data packets or not according to the MUSA numbers.

Description

technical field [0001] The present invention relates to wireless communication technology, and in particular to a retransmission control method, device and terminal (UE, User Equipment) in the process of multi-user shared access. Background technique [0002] The rapid development of mobile Internet, Internet of Things, and other business applications has become the main driving force for the development of the fifth generation mobile communication technology (5G, 5th Generation). They urgently require 5G to have an access rate comparable to optical fiber, a connection capability of hundreds of billions of devices, a perfect real-time experience, and wireless broadband access anytime, anywhere. In addition, important indicators such as energy efficiency, spectrum efficiency, and peak rate also need to be considered comprehensively in the design of 5G systems. In 2013, the IMT-2020 promotion group was established to promote the development of 5G technology. According to the ...
