Problems solved by technology

Although compared with hard handover, the macro-diversity gain of soft handover can improve the communication quality of users at the edge of the cell and make the call transfer between cells smoother, but the update time of the active set of soft handover is slower, which is not conducive to improving the downlink data rate
In fast cell selection, at any moment, the mobile station only selects one cell to send data to, which relatively reduces interference, but it is not easy to combine with multi-antenna technology that can greatly increase capacity

Embodiment Construction

[0019] According to the present invention, a method for increasing the downlink data rate of users at the edge of a sector (cell) in a cellular wireless network is provided. When the user is at the edge of a sector (cell), the mobile station selects one or several link quality parameters according to certain rules. The best sectors (cells) form a sector (cell) group for downlink data transmission, and multiple signals sent by this sector (cell) group are combined at the user end accordingly. in,

[0020] When the received signal of the mobile station at the edge of the sector (cell) is lower than a certain threshold specified by the system, the mobile station selects a group of sectors with the best link quality according to the received transmission signals of the antennas of each sector (cell) (cell), and use the uplink control channel to notify the selected sector (cell) group of the selection result, and the sector (cell) group selected by the mobile station performs corre...

Abstract

The method includes steps: (1) if signal power of mobile station received by users at boundary of sector is lower than power threshold of multiple access cellular communication system, then mobile station measures pilot signal in each sector, and selects out a group of sector with optimal quality of link; moreover, through up going channel, the method informs the selected result to the selected sector group; (2) the selected sector carries out relevant data dispatching, and sends data signal to the mobile station; (3) after receiving data signal dent from the selected sector, the mobile station carries out merger for these signals.

Description

technical field [0001] The invention relates to a downlink fast sector or cell group selection method, which is applicable to any method based on Orthogonal Frequency Division Multiple Access (OFDMA), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA) and other cellular wireless communication systems with multiple access methods. Background technique [0002] In the future, new global communication services will put forward higher requirements on the transmission rate. In particular, how to increase the bit rate of cell edge users has become an issue of great concern to the industry. For example, the long-term evolution system of the 3rd Generation Partnership Project (3GPP) (LTE) specifically proposes this as an important requirement. [0003] At present, the technologies used to solve the transmission rate problem of cell edge users in the mobile communication system mainly include soft handover in code di...
