Method and device for distributing multi-carrier frequency

Abstract

A multi-carrier frequency assignment method is disclosed, which includes: a system detects the number of the carrier frequencies assigned to a terminal, and determines a set of candidate carrier frequencies when the number of the carrier frequencies assigned to the terminal reaches the maximum number of the assigned carrier frequencies which is preset to the terminal; and the system assigns one carrier frequency recommended by the system itself in the set of the candidate carrier frequencies to an set of assigned carrier frequencies of the terminal, and updates the number of the assigned carrier frequencies (105); then the system detects the number of the carrier frequencies assigned to the terminal again. A multi-carrier frequency assignment device is also disclosed. Through this scheme, a certain number of carrier frequencies with optimization of status, which meet the user frequency width limitation and service requirement, can be reasonably and efficiently found out and assigned to the terminal so as to meet the requirement of a high-rate packet data protocol B version system.

Description

technical field [0001] The present invention relates to carrier frequency allocation technology, in particular to a multi-carrier frequency allocation method and device. Background technique [0002] After the High Rate Packet Data (HRPD, High Rate Packet Data) protocol version of Code Division Multiple Access (CDMA, Code Division Multiple Access) technology evolves to version B (RevB, Revision B), the multi-carrier frequency bundling technology is introduced, allowing for A terminal is assigned multiple carrier frequencies at the same time to provide higher data rates. For example, if three carrier frequencies are symmetrically allocated to the front and back directions of the terminal, then the forward direction can provide a peak rate of 14.7 Mbps, and the reverse direction can provide a peak rate of 5.4 Mbps. However, due to the limitation of the terminal itself, the multiple carrier frequencies allocated to the terminal must also be within a certain frequency width, th...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the terminal itself, the multiple carrier frequencies allocated to the terminal must also be within a certain frequency width, that is, the difference between the highest center frequency and the lowest center frequency of the carrier frequency allocated to the terminal cannot exceed a certain threshold

[0003] The existing system only needs to allocate one carrier frequency for the same terminal, so the carrier frequency allocation method does not consider the number of carrier frequencies allocated to the terminal, nor does it consider the maximum frequency difference between the allocated carrier frequencies. Obviously, the current This carrier frequency allocation method can no longer meet the needs of the RevB system
