AI Technical Summary

Problems solved by technology

In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: but if the NHR value of the configuration is relatively large, when the power load of the cell is light, the service cannot reach the limit rate; if the configuration The NHR value is relatively small. When the power load of the cell is light, the capacity of the cell is wasted, so the NHR value set here cannot well meet the needs of the network state.

Description

technical field [0001] The present invention relates to a communication application field, in particular to a method, device and system for adjusting the number of hybrid automatic retransmissions. Background technique [0002] High Speed ​​Uplink Packet Access (High Speed ​​Uplink Packet Access, HSUPA) is a wireless side uplink enhancement technology introduced in the R6 version of the 3rd Generation Partnership Project (3GPP) protocol system. HSUPA uses key technologies such as multi-code transmission, Hybrid Automatic Repeat ReQuest (HARQ), and fast scheduling based on the base station (NodeB), so that the maximum uplink data throughput rate of a single cell can reach 5.76Mbit / s, greatly enhancing the bandwidth The data service bearing capacity and spectrum utilization rate of the code division multiple access (Wideband CDMA, WCDMA) uplink. Five new physical channels are introduced in HSUPA, including: Enhanced Dedicated Physical Data Channel (Enhanced-Dedicated Physical...
