Embodiment Construction

[0034] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0035] The key idea of ​​the present invention is that the terminal notifies the base station of the current data block retransmission information (such as the maximum number of retransmissions allowed and the end of retransmission flag) through the uplink accompanying control signaling while sending the uplink data block, so as to ensure that the base station can Accurately know the retransmission information of each uplink data block, and allocate resources accordingly, thereby avoiding resource waste and ensuring the QoS of service flow.

[0036] Embodiments of the present invention provide a method for uploading data, such as figure 1 As shown, the data uploading method of the embodiment of the present invention is described in detail below.

[0037] Step 1. E...

Abstract

The invention discloses a data uploading and receiving method, which is used for solving the problem that resources are wasted or business flow QoS can not be met caused by disagreement of maximum retransmission times of intellective data blocks of a base station and a terminal. A data uploading method comprises the following steps: the terminal determines a data block which is transmitted for the current time and retransmission information, and then transmits the data block and the retransmission information to the base station on an uplink resource which is allocated by the base station. A data receiving method comprises the following steps: the base station receives the data block and the retransmission information which are transmitted by the terminal, and determines whether to allocate the uplink resource which is used for transmitting the data block according to the fact whether the received data block is correct and the retransmission information. The invention also discloses the base station, the terminal and a data transmission system. Retransmission information of each uplink data block is notified to the base station according to the invention, thereby the invention has the advantages of uniformity of the base station and the terminal which is kept during the process of data retransmission, avoidance of resource waste, and capability of effectively guaranteeing QoS requirements of business flows.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a method for uploading and receiving data, a terminal, a base station and a system. Background technique [0002] In order to meet the growing business needs and improve the utilization of system resources, 3GPP R5 introduced HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) technology, and R6 / R7 introduced HSUPA (High Speed ​​Uplink Packet Access, high-speed uplink packet access) Access) technology, and the standards of the 3GPP LTE (Long Term Evolution, Long Term Evolution) project are also being formulated. In these standards and technologies, shared channels are used to provide services for users, so as to obtain multi-user scheduling and multiplexing gains, and make full use of system resources. [0003] In order to quickly feedback and retransmit the wrongly transmitted data blocks, and make full use of the information carried by the wrong ...
