Description

Method, device and system for detecting data

Technical field

The present invention relates to the field of communications, and in particular, to a method, device, and system for determining interception data.

Background technique

With the rapid development of mobile communications, the lack of bandwidth resources has become a bottleneck restricting the development of mobile communications. The Licensed-Assisted Access using Long Term Evolution (LAA-LTE) system can extend the available spectrum from the licensed spectrum to the unlicensed spectrum to solve the problem of increasingly lacking bandwidth resources. However, since the unlicensed spectrum was originally used by systems such as Wi-Fi, in order to implement friendly coexistence of LAA-LTE systems and Wi-Fi systems on unlicensed spectrum, the LAA-LTE system must adopt "after listening". "Listen-Before-Talk (LBT) channel access mechanism, that is, each time the LAA-LTE system occupies a channel to send an uplink burst or a downlink burst, it must first detect through the channel that the channel is not being Wi-Fi. Wait for the system to occupy.

In practice, it is found that, in the case of self-carrier scheduling, when downlink bursts of different service levels are scheduled for uplink bursts of the same priority, the listening time of the uplink bursts is basically the same, but the listening time of the downlink bursts The difference is that the total waiting time before the user equipment sends an uplink burst to the base station is different, which affects the fairness of channel access.

detailed description

The present application will be described below in conjunction with the accompanying drawings and embodiments.

Referring to FIG. 1, FIG. 1 shows a communication system according to the present invention, in which a base station and a user equipment (UE, User Equipment) communicate with each other through some air interface technology. The base station transmits to the user equipment as a downlink burst, and the user equipment transmits to the base station as an uplink burst. The air interface technology may include: 4G (such as FDD LTE, TDD LTE), and 4.5G, 5G systems, and the like. The base station includes a macro base station, a micro cell, a pico cell, a home base station, a remote radio head, a relay, and the like; the user equipment includes a mobile phone, a laptop computer that can access the LTE system, and a terminal device such as a tablet computer.

In the embodiment of the present invention, the uplink burst may be continuous or discontinuous uplink transmission in the time domain, and the downlink burst may be continuous or discontinuous downlink transmission in the time domain. For example, when the downlink burst A is an uplink transmission using slot 1 and slot 2, the downlink burst A is continuous in the time domain; when the downlink burst B is an uplink transmission using slot 5 and slot 7 Then, the downlink burst B is discontinuous in the time domain. When the uplink burst a is a downlink transmission using slot 3 and slot 4, the uplink burst a is continuous in the time domain; when the uplink burst b is a downlink transmission using slot 6 and slot 8, The upstream burst b is not continuous in the time domain.

In the embodiment of the present invention, the downlink burst may include a scheduling instruction for scheduling an uplink burst, or may not include scheduling signaling for scheduling an uplink burst. For example, when the downlink burst A is a downlink transmission using slot 1 and slot 2, the uplink burst a is an uplink transmission using slot 3 and slot 4, and the downlink burst B is using slot 5 and Downlink transmission of slot 6, uplink burst b is uplink transmission using slot 7 and slot 8, and downlink burst B does not include scheduling signaling for scheduling uplink burst a, downlink burst B When the scheduling signaling for scheduling the uplink burst b is included, the downlink burst and the uplink burst described in the text may be the downlink burst A and the uplink burst b, respectively, or may be the downlink burst B and the uplink. Burst b.

It can be understood that, when the downlink burst includes a scheduling instruction for scheduling an uplink burst, the uplink burst is a continuous uplink transmission in the time domain, and the uplink burst and another adjacent uplink burst The downlink burst is a continuous downlink transmission in the time domain, and the downlink burst is discontinuous with other adjacent downlink bursts in the time domain.

For a better understanding of the embodiments of the present invention, please refer to FIG. 2, which is an interaction diagram of an application scenario of the present invention. The application scenarios of the embodiments of the present invention are described below.

The base station first obtains the service level of the downlink burst, and determines the listening parameter of the downlink burst according to the service level of the downlink burst. Then, the base station performs the idle channel evaluation on the downlink channel according to the listening parameter of the downlink burst, and performs idle according to the execution. The result of the channel evaluation determines whether a downlink burst is sent. When it is determined that the downlink burst is sent, the base station sends a downlink burst to the user equipment, where the base station needs to receive the uplink burst of the user equipment, and the downlink burst includes the scheduling signaling that the scheduling user equipment sends the uplink burst. After receiving the downlink burst sent by the base station, the user equipment sends an uplink burst according to the scheduling signaling included in the downlink burst. Then, the user equipment acquires the service level of the uplink burst, and determines the interception parameter of the uplink burst according to the service level of the uplink burst, and evaluates the idle channel of the uplink channel according to the interception parameter of the uplink burst. The user equipment determines whether to send an uplink burst according to the result of performing the idle channel evaluation. In the true When the uplink burst is sent, the user equipment sends an uplink burst to the base station.

Therefore, before the user equipment sends an uplink burst to the base station, it needs to perform two interceptions: the first time is to listen to the downlink channel carrying the downlink burst, and the second time is to detect the uplink channel carrying the uplink burst. listen. Therefore, the total waiting time before the user equipment sends the uplink burst to the base station includes the listening time of the downlink burst and the listening time of the uplink burst.

The listening time of the downlink burst is directly determined by the listening parameter of the downlink burst, and the listening parameter of the downlink burst is directly determined by the service level of the downlink burst; the listening time of the uplink burst is determined by the uplink. The burst listening parameters are directly determined, and the listening parameters of the uplink burst are directly determined by the service level of the uplink burst. Therefore, when the downlink bursts with different service levels are scheduled for the uplink burst of the same service level, the listening time of the uplink burst is basically the same, but the listening time of the downlink burst is not the same, causing the user equipment to send the same to the base station. The total waiting time before the uplink burst of the service level is different, which affects the fairness of channel access.

For the deficiencies of the application scenario described in FIG. 2, referring to FIG. 3, an embodiment of the present invention discloses a method for determining interception data, including the following steps:

The base station acquires the service level of the downlink burst, and determines the downlink burst listening data according to the service level of the downlink burst. The determining unit acquires the interception data of the uplink burst to determine the interception data of the uplink burst, wherein the determining factor of the interception data of the uplink burst includes the interception data of the downlink burst. After determining the interception data of the uplink burst, the base station sends the interception data of the uplink burst to the user equipment by using the downlink control signaling, where the downlink control signaling includes the interception data of the uplink burst. After receiving the downlink control signaling sent by the base station, the user equipment obtains the interception data of the uplink burst from the downlink control signaling.

The base station performs idle channel evaluation according to the downlink burst listening data, and determines whether to send a downlink burst according to the result of performing the idle channel evaluation. When it is determined that the downlink burst is transmitted, the base station sends a downlink burst to the user equipment. After receiving the downlink burst sent by the base station, the user equipment performs the idle channel evaluation according to the intercepted data of the uplink burst, and determines whether to send the uplink burst according to the result of performing the idle channel evaluation. When it is determined that the uplink burst is sent, the user equipment sends an uplink burst to the base station.

Compared with the prior art, the interception parameter of the uplink burst is determined according to the service level of the uplink burst, and the service level of the downlink burst is determined only according to the service level of the downlink burst. In this embodiment, the base station determines the uplink. The sudden listening data not only considers the service level of the uplink burst, but also considers the next The bursty listening data is such that the total waiting time before the user equipment sends the uplink burst of the same service level to the base station tends to be consistent, thereby improving the fairness of channel access.

In an optional implementation manner, the downlink burst listening data may be at least one of the following: a service level of the downlink burst, and all or part of the listening parameters of the downlink burst. The interception data of the uplink burst may be all or part of the interception parameter of the uplink burst, or may be the priority indication of the uplink burst. The all listening parameters of the downlink burst include a minimum contention window length, a maximum contention window length, a maximum persistent channel occupation time, a contention window length, a backoff counter initial value, a contention window length set, a waiting time, and the like. All listening parameters of the uplink burst include a minimum contention window length, a maximum contention window length, a maximum persistent channel occupation time, a contention window length, a backoff counter initial value, a contention window length set, a waiting time, and the like.
