Abstract

The embodiment of the invention discloses a data transmission method, system and base station of the high speed downward grouping access. The technical solution of the embodiment of the invention activates the HS-SCCH less operation, when the base station judges to use the HS-SCCH less operation or non HS-SCCH less operation, the base station firstly judges whether the to-be transmitted data quantity is sufficient; if the data quantity is sufficient, the base station decides whether to select the HS-SCCH less operation according to the TBS size according to the HS-SCCH less operation or non HS-SCCH less operation, so that the base station obtains larger cargo-handling capacity; if the to-be transmitted data quantity is not sufficient, the TBS size of the HS-SCCH less operation and the non HS-SCCH less operation are compared under the same resource condition to device whether to decide to select the HS-SCCH less operation, so that the base station obtains greater resource using efficiency.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a transmission method, system and base station for high-speed downlink packet access data. Background technique

[0002] High Speed ​​Downlink Packet Access (HSDPA) and High Speed ​​Uplink Packet Access (High Speed Speed ​​Uplink Packet Access, HSUPA), collectively referred to as high speed packet access (High Speed ​​Packet Access, HSPA) technology. Among them, HSDPA has the characteristics of high speed, and the highest rate can reach about 14Mbps, so it has been promoted and applied very quickly.

[0003] In HSDPA, enhanced technologies such as adaptive modulation and coding (Adaptive Modulation and Coding, AMC) and hybrid adaptive repeat request (Hybrid Automatic Repeat Request, HARQ) are used to improve downlink throughput. The HSDPA modulation method adopts Quaternary Phase Shift Keying (Quaternary Phase Shift Keying, QPSK) and 16 quadrature amplitude modulation (1...
