Abstract

The invention discloses a PDCCH channel encoding rate regulation method and an evolution base station, relating to the field of mobile communication. The method comprises the following steps: obtaining the radio link quality information of user equipment; according to the radio link quality information of user equipment, determining a link quality regulation zone to which the radio link quality ofthe user equipment belongs; and according to the link quality regulation zone, regulating the PDCCH channel encoding rate occupied by the user equipment. The base station comprises an acquisition module and a regulation module so as to reasonably choose the PDCCH channel encoding rate according to the practical condition of the current user equipment link quality, thus improving the utilization efficiency of controlling resource. Specifically, the embodiment of the invention improves the efficiency for the PDCCH channel to transmit scheduling Information to a user, thus improving the user number simultaneously scheduled by the same TTI and reducing the waiting time delay of user data on the sending side.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a PDCCH channel coding rate adjustment method and an evolved base station. Background technique [0002] LTE (Long Term Evolution, long-term evolution) technology adopts a flat network structure in the network structure, that is, only eNodeB (evolved Node B, evolved base station) nodes are reserved on the access network side, and the RNC ( Radio Network Controller, radio network controller) node, the radio resource management function originally performed by the RNC node is performed by the eNodeB node. [0003] The LTE system uses a shared channel to carry user's uplink and downlink data transmission in both uplink and downlink. This bearer method can make full use of limited time-frequency resources. In a shared channel system, the eNodeB performs unified control and scheduling of channel resources used to carry user data. Before user data transmission, the eNodeB uses the...
