Embodiment 1

[0089] CQI reporting methods include: periodic reporting (reporting every several milliseconds) or event-triggered reporting (such as reporting when the CQI value changes), and the like.

[0090] 220: Receive the CQI reported by the user equipment according to the reporting manner.

[0091] 230: Determine the downlink load of the cell where the user equipment is located according to the received CQI.

[0092] The base station determines the SINR (signal-to-noise ratio) of the user equipment according to the received CQI; calculates the average SINR of the cell according to the SINR of all user equipment in the cell where the user equipment is located; determines the SINR according to the average SINR and the preset target signal-to-noise ratio The downlink load of the cell.

[0093] In the embodiment of the present invention, the downlink load of a cell in a wireless communication system is determined through the CQI reported by the user equipment, so that the cell load can b...

Embodiment 2

[0097] The base station notifies the user equipment of the CQI reporting manner in the downlink control messages at the radio network control layer, data link layer, and physical layer. CQI reporting methods include: periodic reporting (reporting every several milliseconds) or event-triggered reporting (such as reporting when the CQI value changes), and the like.

[0098] 320: Receive the CQI reported by the user equipment according to the reporting manner.

[0099] The user equipment has been continuously measuring the SINR, and maps the MCS (Modulation and Coding Scheme, modulation and coding scheme) of the user equipment according to the measured SINR value, and then obtains the CQI value according to the MCS table lookup, according to the CQI specified by the base station In the reporting mode, the CQI is reported to the base station in the specified uplink control channel. The base station receives the CQI reported by the user equipment according to the reporting manner....

Embodiment 3

[0117] If the number of users accepted by the base station in the target cell is not less than (including greater than or equal to) the number threshold, it will notify the user equipment of the CQI reporting method and the user equipment reception method in the downlink control messages of the radio network control layer, data link layer, and physical layer. Signal strength reporting method. The CQI reporting manner may include: periodic reporting (reporting every several milliseconds) or event-triggered reporting (such as reporting when the CQI value changes), and the like. The received signal strength reporting method may be periodic reporting, or reporting according to the time specified by the base station, and so on.

[0118] 420: Receive the CQI reported by the user equipment according to the CQI reporting manner and the received signal strength reported by the received signal strength reporting manner.

[0119] The user equipment has been continuously measuring the SI...

Abstract

The invention embodiment discloses a down-link load determining method, base station and system, belonging to the 3G communication system field. The method comprises: notifying user equipment the channel quality indication (CQI) reporting mode; receiving the CQI reported by the user equipment according to the above reporting mode; and determining the down-link load of the user equipment in the cell according to the received CQI. The base station comprises: a reporting mode notification module, for notifying user equipment the channel quality indication (CQI) reporting mode; a reception module, for receiving the CQI reported by the user equipment according to the above reporting mode; a first determination module, for determining the down-link load of the user equipment in the cell according to the received CQI. The system comprises a base station and user equipments; The base station is used for notifying user equipment the CQI reporting mode; receiving the CQI reported by the user equipment according to the above reporting mode; and determining the down-link load of the user equipment in the cell according to the received CQI. The embodiment of the invention can perform load control better.

Description

technical field [0001] The invention relates to the field of 3G communication systems, in particular to a method for determining downlink load, a base station and a communication system. Background technique [0002] In order to meet the challenge of Wimax (World Interoperability for Microwave Access), 3GPP (the 3rd Generation Partner Project, 3rd Generation Partnership Project) needs to propose a more Competitive technologies to meet the system's high-speed, low-latency, large-capacity, and wide-coverage requirements. The technology embodied in the access network is the LTE (Long Time Evolution, long time evolution) technology. [0003] figure 1 It is a common LTE network architecture. Wherein, 101 is a mobility management entity or a serving gateway, 102 is an eNB (Evolved Universal Terrestrial Radio Access Network NodeB), an evolved universal terrestrial radio access network base station), and 103 is a UE (User Equipment, user equipment). The Uu interface is the air i...
