Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0059] The present invention introduces a sliding window in space division judgment to calculate the invalid frame probability of the first N frames of each frame, and performs space division judgment according to the calculated probability. Among them, N is the length of the sliding window.

[0060] The method that the present invention carries out space division judgment specifically comprises the following steps:

[0061] Step 1: Use the existing space division judgment method for the first N-1 frames to determine whether to perform space division.

[0062] That is to say, for the first N−1 frames, it is firstly determined whether each subframe is an invalid frame or a valid frame. If the channel estimation result (filtering or instantaneous path p...

Abstract

The invention provides a method and a device of space division decision, the invalid frame probability of top N frames of each frame is calculated through introducing of sliding windows to the space division decision, and the space division decision is carried out according to the calculated probability. Accuracy of the space division decision is improved, so that the space division probability is increased under the condition that actual channel isolation is very high, and the space division probability is decreased under the condition that the actual channel isolation is very low.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for space division judgment. Background technique [0002] In an indoor environment, if the isolation between two channels is large, it can be considered that the interference between the two users is very small, and the space separation condition is satisfied, and the two users can use the same uplink resource (for example: to schedule two channels at the same time). HSUPA users using the same resources) or downlink resources (for example: scheduling two HSDPA users using the same resources at the same time). [0003] figure 1 A schematic diagram of the space division for two users. figure 1 For example, the HSUPA space division in the above row, where: [0004] UE1 and UE2 represent two users respectively; [0005] i is the strongest channel group number of UE1, j is the strongest channel group number of UE2; [0006] M is the number of cha...
