Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a base station for transmitting data based on a wireless backhaul link.
Background
With the rapid development of mobile internet services, mobile networks also need to deploy more base stations to increase higher network capacity. The deployment of the base station firstly needs to solve the data return problem, namely, the data intercommunication between the base station and the mobile core network is completed. In a traditional data return mode, optical fibers are directly deployed between a base station and a transmission switch, so that high-speed, stable and high-reliability transmission guarantee is provided. However, the deployment cost of the transmission mode of the straight-through optical fiber is high, the construction time is long, and as the base station deploys and encrypts gradually, not all the sites have the condition for deploying the straight-through optical fiber. In order to improve the deployment flexibility and solve the deployment problem in the absence of wired backhaul link, a wireless backhaul transmission mode is adopted.
The wireless backhaul network includes a user service base station, a backhaul Customer Premises Equipment (CPE), and a backhaul base station, where the user service base station provides a wireless network access service for an end user, and the user service base station and the backhaul CPE are integrated together on hardware. When the user service base station wants to transmit user uplink data to the core network, the user service base station transmits the data to the return base station by the return CPE through the uplink wireless return link, and the return base station transmits the data to the core network by using the straight-through optical fiber link or other wireless return links; correspondingly, when the core network wants to send the user downlink data to the user service base station and then transmit the user downlink data to the end user, the core network firstly transmits the data to the backhaul base station, the backhaul base station then sends the data to the backhaul CPE by using the downlink wireless link, and the backhaul CPE transmits the data to the user service base station.
In the existing wireless backhaul scheme, when there is only one wireless backhaul link, the backhaul CPE directly transmits data to the only relay base station (backhaul base station), or the only relay base station transmits data to the backhaul CPE. However, as the deployment density of base stations increases, the wireless backhaul scheme will be more widely applied, and at the same time, the network will become more complex, wireless network signals of multiple frequencies and multiple cells are overlapped, for the backhaul CPE, multiple backhaul links may be selected at the same time, and at this time, how to select a suitable link or links from the multiple wireless backhaul links becomes a problem to be solved.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
As shown in fig. 1, an application scenario one provided in the embodiment of the present invention includes: the method includes the steps that a user service base station, a plurality of backhaul base stations (relay base stations) and a core network are formed, a plurality of wireless backhaul links (backhaul links for short in fig. 1) are formed between the user service base station and the plurality of backhaul base stations, when the user service base station intends to transmit user uplink data to the core network, the user service base station transmits the data to the backhaul base stations through the backhaul base stations by means of the plurality of wireless backhaul links, and the backhaul base stations transmit the data to the core network by means of straight-through optical fiber links or other wireless backhaul links.
As shown in fig. 2, an application scenario two provided in the embodiment of the present invention includes: a user serving base station, a first backhaul base station (relay base station) and a plurality of second backhaul base stations and a core network, a plurality of wireless backhaul links (referred to as backhaul links in fig. 2) are formed between the first backhaul base station and a plurality of second backhaul base stations, when the user service base station intends to transmit user uplink data to the core network, the user service base station transmits the data to the first backhaul base station through the first backhaul base station by means of a wireless backhaul link between the user service base station and the first backhaul base station, the first backhaul base station transmits the data to the second backhaul base station through the second backhaul base station by means of a wireless backhaul link between the first backhaul base station and a plurality of second backhaul base stations, and the second backhaul base station transmits the data to the core network by means of a straight-through optical fiber link or other wireless backhaul links, in the first application scenario, a suitable link is mainly selected from a plurality of wireless backhaul links between a first backhaul base station and a plurality of second backhaul base stations.
It should be noted that, the communication generally includes two types, namely, fronthaul and backhaul, where: the forward transmission refers to data transmission between the terminal and the ue, while the backward transmission refers to data transmission between the ue, the backward base station, and the core network, and the link used when the ue, the backward base station, and the core network transmit data is called a wireless backward link, which includes an uplink transmission link and a downlink transmission link.
Example 1
Based on the above two application scenarios, an embodiment of the present invention provides a method for transmitting data based on a wireless backhaul link, as shown in fig. 3, where the method includes:
101. and transmitting the first data to be transmitted back through at least two candidate wireless transmission links, and counting the transmission rates of the at least two candidate wireless transmission links in the process of transmitting the first data to be transmitted back.
The backhaul data refers to data that is backhaul via a wireless backhaul link, and the backhaul data may be invalid data or valid data. The valid data refers to uplink data sent by the terminal or the user serving base station, whereas other data is invalid data, for example: test data or the like generated randomly or set in advance may be regarded as invalid data. Here, the first data to be transmitted back may be invalid data or valid data.
For example, if the backhaul data is invalid, the at least two candidate wireless backhaul links may transmit the same invalid data, or may transmit different invalid data; if valid data is returned, usually the valid data returned by the at least two candidate wireless return links is different.
102. And transmitting the second data to be transmitted back through the wireless back transmission link with the highest back transmission rate in the at least two candidate wireless back transmission links.
The second data to be transmitted back refers to uplink data transmitted by the terminal or the user serving base station.
Preferably, the length of the first data to be transmitted back by each candidate wireless backhaul link is the same.
Illustratively, the length of the first to-be-backtransmitted data is greater than or equal to the maximum number of uplink transmission bits per TTI in the 3GPP standard.
Optionally, after counting the backhaul rates of the at least two candidate wireless backhaul links in step 101 and before step 102, the method further includes:
101a, sorting at least two candidate wireless backhaul links according to the magnitude of backhaul rate.
Through the above-mentioned sorting process of 101a, the base station can select the wireless backhaul link with the highest transmission rate from the sorting so as to transmit the second data to be backhauled by using the wireless backhaul link with the highest transmission rate.
Based on the above, the step 102 specifically includes the following steps:
102a, under the condition that the time from the counted return rate of at least two candidate wireless return links to the current moment is less than the threshold, transmitting the second data to be returned through the wireless return link with the highest return rate.
For example, the time from the statistics of the backhaul rates of the at least two candidate wireless backhaul links to the current time may be set by a timer, or may be set by the timer.
Optionally, based on the above, the method further includes:
102b, under the condition that the time from the counting of the return rate of the first candidate wireless return link to the current moment is greater than the threshold and the length of the second data to be returned is greater than the first data to be returned, the return rate of the first candidate wireless return link is counted again.
Wherein the first candidate wireless backhaul link is any one of at least two candidate wireless backhaul links.
For example, the implementation procedure of the step of re-counting the backhaul rate of the first candidate wireless backhaul link can refer to the content of step 201. Specifically, the first candidate wireless backhaul link is used to transmit the first to-be-backhaul data, and the backhaul rate of the first candidate wireless backhaul link during the transmission of the first to-be-backhaul data is counted.
And/or the presence of a gas in the gas,
the step 102 specifically includes the following steps:
102c, transmitting the second data to be transmitted back through the wireless transmission link with the highest transmission rate in the at least two candidate wireless transmission links under the condition that the time from the statistics of the transmission rates of the first candidate two wireless transmission links to the current moment is greater than the threshold and the length of the second data to be transmitted back is less than the length of the first data to be transmitted back.
Example 2
Based on the above, a specific implementation will be given below.
As shown in fig. 4, the method includes the following:
201. and transmitting the first data to be transmitted back through at least two candidate wireless transmission links, and counting the transmission rates of the at least two candidate wireless transmission links in the process of transmitting the first data to be transmitted back.
202. A timer is set for each wireless backhaul link and starts timing from zero.
It should be noted that, if the base station uses a certain wireless backhaul link to backhaul data, and obtains the backhaul rate of the certain wireless backhaul link, the base station sets a timer for the wireless backhaul link, and the timer starts to count time from zero. Since the base station always uses the wireless backhaul link to transmit data, the backhaul rate of the wireless backhaul link is always in an updated state, and therefore, it is not necessary to count the backhaul rate of the wireless backhaul link that always transmits data again.
203. It is determined whether there is a first candidate wireless backhaul link with a timing time greater than a threshold, if yes, step 204 is performed, otherwise step 205 is performed.
204. It is determined whether the length of the second data to be transmitted back is smaller than the length of the first data to be transmitted back, if yes, step 205 is executed, otherwise, step 206 is executed.
205. And transmitting the second data to be backtransmission through the wireless backtransmission link with the highest backtransmission rate.
206. And re-counting the backhaul rate of the first candidate wireless backhaul link.
For example, the above-mentioned specific implementation process of step 206 may refer to the content of step 201. Specifically, the first candidate wireless backhaul link is used to transmit the first to-be-backhaul data, and the backhaul rate of the first candidate wireless backhaul link during the transmission of the first to-be-backhaul data is counted.
In the method for transmitting data based on wireless backhaul links provided in the embodiments of the present invention, a base station transmits first data to be backhaul through at least two candidate wireless backhaul links, and counts backhaul rates of the at least two candidate wireless backhaul links in a process of transmitting the first data to be backhaul; and transmitting the second data to be transmitted back through the wireless back transmission link with the highest back transmission rate in the at least two candidate wireless back transmission links.
