Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiments of the present invention provide a time slot allocation method based on adaptive beamforming. The method first selects at least one time slot according to the service type of a new access user, and then selects at least one time slot according to the The shape gain function or array direction vector of the new access user is used to calculate the correlation coefficient between the accessed user and the new access user in the candidate time slot, and then according to the correlation coefficient for the new access user from the candidate time slot Select the candidate time slot with the smallest average value of the correlation coefficient as the time slot to be accessed.

Abstract

The embodiment of the invention discloses a time slot allocation method based on self-adaptive beam-forming, which comprises: A, at least one alternative time slot is selected; B, the correlation coefficient of all connected users and newly-connected users in the alternative time slot is calculated according to the beam-forming gain function or array directional vector, wherein, the correlation coefficient is used for expressing the relations between the users; C, a time slot is chosen from the alternative time slots for the newly-connected users as a time slot to be connected according to the correlation coefficient. The embodiment also discloses a time slot allocation device based on the self-adaptive beam-forming, which comprises a calculating module and a selecting module. By adoptingthe slot allocation method and the slot allocation device, the interference between the newly-connected users and the connected users can be effectively reduced and the practical capacity and servicequality of the users can be improved.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a time slot allocation method and device based on adaptive beamforming. Background technique [0002] Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division Synchronous Code Division Multiple Access) technology is a third-generation mobile communication technology standard proposed by my country. It has the characteristics of large system capacity, high spectrum utilization rate, and strong anti-interference ability. The optimal scheme for building the third generation mobile communication network system. [0003] In practical applications, the TD-SCDMA system uses a variety of advanced technologies, among which the Smart Antenna (SA, Smart Antenna) technology is one of the core technologies in the TD-SCDMA system and has been applied to the multi-carrier TD-SCDMA system on the base station. [0004] Smart antenna technology is a new technology...
