本发明涉及通信技术领域，特别是指一种直放站参数调整方法及装置。The invention relates to the field of communication technology, in particular to a method and device for adjusting parameters of a repeater.
背景技术Background technique
直放站是用来解决现网覆盖问题的一种网络结点，与IAB(Integrated Accessand Backhaul，集成接入和回传)、中继技术相比，直放站具备更低复杂度更低成本的优势。但直放站不具备回传链路上行功率控制能力，仅能通过固定增益放大的方式对上行接收到的信号进行放大。The repeater is a network node used to solve the coverage problem of the existing network. Compared with IAB (Integrated Access and Backhaul, integrated access and backhaul) and relay technology, the repeater has lower complexity and lower cost The advantages. However, the repeater does not have the ability to control the uplink power of the backhaul link, and can only amplify the received uplink signal through fixed gain amplification.
现网中直放站接入链路以及回传链路增益采用固定增益方式，一旦完成直放站的网络部署，则其放大增益不会发生改变。In the existing network, the gain of the access link of the repeater and the return link adopts a fixed gain method. Once the network deployment of the repeater is completed, its amplification gain will not change.

具体实施方式Detailed ways
为使本发明的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
相关技术规定频率范围1(FR1)直放站上行回传链路输出功率至少包含两个水平，其一大于任意终端的最大输出功率，标准化不规定最大输出功率值；其二小于等于任意终端的最大输出功率。若直放站功率过大，直放站功率提升引入了同频干扰问题(co-channelinterference issue)，提升了基站接收底噪，降低信噪比(Signal-to-noise ratio，SNR)，影响基站接收其他非直放站放大信号。若直放站功率过小，则上行覆盖可能受限。此外可以通过提升直放站增益，降低终端发射功率的方式节约终端功耗。The relevant technology stipulates that the frequency range 1 (FR1) repeater uplink backhaul link output power includes at least two levels, one is greater than the maximum output power of any terminal, and the standardization does not stipulate the maximum output power value; the other is less than or equal to any terminal maximum output power. If the power of the repeater is too large, the power increase of the repeater will introduce co-channel interference issue, which will improve the base station receiving noise floor, reduce the signal-to-noise ratio (SNR), and affect the base station Receive other non-repeater amplified signals. If the repeater power is too low, the uplink coverage may be limited. In addition, the power consumption of the terminal can be saved by increasing the gain of the repeater and reducing the transmit power of the terminal.
目前存在的主要问题是如何兼顾直放站覆盖以及直放站引入的同频干扰问题，同时尽量降低直放站覆盖下终端的功耗。The main problem at present is how to take into account the repeater coverage and the co-channel interference introduced by the repeater, and at the same time reduce the power consumption of the terminal under the repeater coverage as much as possible.

一实施例中，基站可以根据PHR判断存在已经按照最大发射功率进行发射的终端甲，但对应接收功率依旧低于目标值，假设差值为X，则提升直放站增益和/或直放站最大输出功率上限，同时可根据直放站增益变化值适当降低该直放站覆盖范围内的其他终端上行功控值。In one embodiment, the base station can judge according to the PHR that there is a terminal A that has transmitted at the maximum transmission power, but the corresponding received power is still lower than the target value, assuming that the difference is X, then increase the gain of the repeater and/or the repeater The upper limit of the maximum output power, and at the same time, the uplink power control value of other terminals within the coverage of the repeater can be appropriately reduced according to the gain change value of the repeater.
其中判断是否需要调整直放站最大输出功率上限的判决条件包括：判断当前直放站在提升增益后是否会超过现有规定的直放站最大输出功率上限，若超过，则相应提升直放站最大输出功率上限，否则不提升最大输出功率上限。网络侧提升直放站增益Y dB，其中Y-X大于等于Z，Z由基站动态接收范围以及ICS(in-channel selectivity)射频指标决定，在对直放站增益进行提升后，降低该直放站服务的与终端甲一起进行上行调度的其他终端的上行功控ZdB或者使基站接收的信号功率等于目标接收功率。The judgment conditions for judging whether the maximum output power limit of the repeater needs to be adjusted include: judging whether the current repeater will exceed the existing maximum output power limit of the repeater after increasing the gain, and if so, increase the repeater accordingly The upper limit of the maximum output power, otherwise the upper limit of the maximum output power will not be increased. The network side increases the gain of the repeater by Y dB, where Y-X is greater than or equal to Z, and Z is determined by the dynamic receiving range of the base station and the radio frequency index of ICS (in-channel selectivity). After the gain of the repeater is increased, the service of the repeater is reduced.

The network side increases the gain of the repeater by B dB. The choice of B is determined by the dynamic receiving range of the base station and the radio frequency index of ICS (in-channel selectivity). One of the principles for formulating B is to ensure that the highest received signal power received by the current base station is increased by B dB In the future, the dynamic receiving range and ICS requirements of the base station can be met. Under this principle, the largest B can be selected or a suitable B can be obtained; after the repeater gain is increased, the uplink power control usage of all terminals served by the repeater can be reduced.
