Problems solved by technology

However, this requires the receiver of the terminal to store 16 data blocks, which also requires the terminal to have a large data buffer area and strong service processing capabilities. For services mainly used for low data transmission volume and high delay tolerance For the terminal, it needs to increase the complexity and increase the cost

specific Embodiment 1

[0127] In the specific embodiment 1, the above-mentioned notification method of "notifying its hybrid automatic retransmission capability to the network side device" and the above-mentioned hybrid automatic retransmission of "having both limited downlink hybrid automatic retransmission capability and limited uplink hybrid automatic retransmission capability" are used ability mode. In addition, the terminal notifies the network side device of its hybrid automatic repeat capability through a terminal capability information message (UE Capability Information) in the attach process.

[0128] The process of terminal A reporting its hybrid automatic retransmission capability to the network side is as follows figure 2 shown:

[0129] Step 201: Terminal A initiates a random access procedure in the cell where it resides, and establishes a Radio Resource Control (RRC) connection.

[0130] Step 202 , in the process of establishing the RRC connection, the terminal A sends an attach req...

specific Embodiment 2

[0152] In the specific embodiment 2, the above-mentioned notification method of "notifying the network side device of the identifier representing the hybrid automatic retransmission capability" is used. And, the terminal notifies the network side device of the identification through a radio resource control connection request (RRC Connection Request) message. like Figure 4 shown, including:

[0153] Step 401: Terminal A initiates random access in the cell where it resides, and sends an RRC connection request (RRC Connection Request) message to the base station to which the cell belongs.

[0154]In this embodiment, in order to implement the present invention, the terminal A carries an identifier indicating the hybrid automatic repeat capability in the RRC Connection Request (RRC Connection Request) message, and the identifier may be a low-speed terminal identifier, or a low-cost terminal identifier, or It is a low-priority terminal identifier, and an information element can ...

specific Embodiment 3

[0166] In the specific embodiment 3, the above-mentioned notification method of "notifying the network side device of the identifier representing the hybrid automatic retransmission capability" is used. In addition, the terminal notifies the network side device of the identifier indicating the limited hybrid automatic retransmission capability through a radio resource control connection setup complete (RRC Connection Setup Complete) message. like Figure 5 shown, including:

[0167] Step 501: Terminal A initiates random access in the cell where it resides, and sends an RRC connection request (RRC Connection Request) message to the base station to which the cell belongs.

[0168] Step 502 , after receiving the RRC connection request (RRC Connection Request) message sent by the terminal, the base station sends an RRC connection setup (RRC Connection Setup) message to the terminal A.

[0169] Step 503 , after receiving the RRC Connection Request (RRC Connection Request) message...

Abstract

The invention discloses a method, a system, and a terminal for processing hybrid automatic repeat-request. The method comprises that: the terminal notifies network-side equipment of hybrid automatic repeat-request capability of the terminal or an identification representing the hybrid automatic repeat-request capacity, and the network-side equipment carries out resource scheduling on the terminal according to the hybrid automatic repeat-request capacity of the terminal. The method, the system, and the terminal of the invention can reduce demands of the terminal for cache capacity and business processing capacity, thereby reducing cost of the terminal and being benefit for widespread applications of the terminal.

Description

technical field [0001] The present invention relates to the field of mobile communications, and in particular, to a method and system for processing hybrid automatic retransmission, and a terminal. Background technique [0002] With the rapid development of wireless communication technology, many new communication technologies have been born on the basis of traditional communication technologies, and these new communication technologies have spawned various communication business needs, such as smart phones (Smart Phone), machine type communication MTC (Machine Type Communication, MTC for short) and so on. The salient features of these new communication services are, for example, that the types of services involved are relatively single, the amount of data transmitted (received and sent) each time is small, and some services have delay tolerance performance. [0003] In the existing communication protocol framework, the Hybrid Automatic Repeat-reQuest (HARQ) technology used...
