specific Embodiment approach

[0050] On the basis of the above embodiments, this embodiment relates to a specific method for determining a semi-static activation interval, that is, a specific implementation manner of the above step S101 is:

[0051] The semi-static activation interval is determined according to the result of taking the modulus of the cell ID and 2.

[0052] Specifically, for a specific cell, when determining which semi-static activation interval is used by the cell, the base station determines the semi-static activation interval according to the cell identifier and the result of modulo 2. The cell ID is a number that uniquely identifies the cell, and the cell ID is modulo 2. In an optional scheme, if the result of taking the modulus of the cell identifier and 2 is 0, then determine that the semi-static activation interval corresponding to the cell is the first semi-static activation interval; if the result of the modulus of the cell identifier and 2 is 1, Then it is determined that the se...

Abstract

The invention provides a semi-persistent scheduling method and a base station. The method comprises the steps of determining a semi-persistent activation section which is a first semi-persistent activation section or a second semi-persistent activation section, wherein sub-frames corresponding to the first semi-persistent activation section are not overlapped with sub-frames corresponding to the second semi-persistent activation section; and executing semi-persistent activation on the sub-frames in the semi-persistent activation section. According to the method, the quantity of the sub-frames used for semi-persistent activation can be greatly increased, so that the condition that adjacent cells can use the sub-frames of which the positions are sufficiently nonoverlapping is ensured, and thus a randomized interference effect is ensured.

Description

technical field [0001] The present invention relates to communication technology, in particular to a semi-static scheduling method and a base station. Background technique [0002] In a Long Term Evolution (LTE for short) system, adjacent cells may be on the same frequency or may be on different frequencies. When adjacent cells are on the same frequency, when semi-persistent scheduling (Semi-Persistent Scheduling, referred to as SPS), it is necessary to stagger the semi-static activation positions of adjacent cells to avoid co-frequency interference between adjacent cells. In order to achieve randomization of interference. When the adjacent cells have different frequencies, the terminal needs to measure the neighboring cells with different frequencies. If the radio terminal of the terminal does not support dual transmitters, the radio terminal needs to adopt a GAP period. During the GAP period, the terminal will switch the frequency to the frequency of the neighboring cell...
