Method for adjusting channel occupancy probability, adjusting system and equipment

Abstract

Provided in the present invention are a channel occupation probability adjustment method, channel occupation probability adjustment system, and a device having base station function. The channel occupation probability adjustment method comprises: according to a data type of data to be transmitted of a device having a base station function, adjusting parameter information of a channel detection mechanism corresponding to the data to be transmitted; according to the adjusted parameter information, adjusting the probability of the data to be transmitted occupying a downlink channel, wherein, the data type of the data to be transmitted comprises: a discovery reference signal and / or downlink data. The technical solution of the present invention can improve the ability of an LBT mechanism transmitting a detection reference signal (DRS) to preempt a channel, so as enable the DRS to more easily occupy the channel or at least have a same probability of preempting a channel as a LBT mechanism transmitting common downlink data, thereby reducing power consumption of the DRS of the terminal, performing a cell identification, downlink synchronization and time-frequency estimation, and improving accuracy.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a channel occupation probability adjustment method, a channel occupation probability adjustment system and a device with base station functions. Background technique [0002] With the rapid increase of communication traffic, the authorized spectrum of 3GPP is increasingly insufficient to provide higher network capacity. In order to further improve the utilization of spectrum resources, 3GPP is discussing how to use unlicensed spectrum, such as 2.4GHz and 5GHz frequency bands, with the help of licensed spectrum. These unlicensed spectrums are currently mainly used by Wi-Fi, Bluetooth, radar, medical and other systems. [0003] Usually, access technologies designed for licensed frequency bands, such as LTE (Long Term Evolution, long-term evolution) are not suitable for use in unlicensed frequency bands, because access technologies such as LTE have very high require...

Problems solved by technology

However, if the time when the LAA cell on the same frequency sends the reference signal DRS is too random, the terminal needs to consume more power in order to measure the adjacent cell, especially when measuring at different frequencies, it may not be possible because the adjacent cell does not seize the channel. Send DRS so that the terminal cannot even detect the reference signal DRS of a neighboring cell during the measurement gap

Moreover, if the LAA cell cannot send the reference signal DRS for a long time, the measurement accuracy of the terminal will be low
