detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 and 2 show schematic diagrams of a wireless communication system in accordance with an embodiment of the present invention. Three nodes are involved, namely the upper node 10, the radio frequency node 20 and the wireless transceiver 30. The radio frequency node 20 and its upper node 10 form one end of wireless transmission and reception, and the other end of the radio transmission and reception is a wireless transceiver 30.

The most important feature of the RF node 20 is to complete the transmission and reception of the radio frequency function. In addition, the L1, L1+L2, or L1+L2+L3 functions of the wireless function can be implemented, and the upper node 10 completes other parts of the wireless function. For example, if the radio frequency node 20 only performs the L1 function, the upper node 10 completes the L2+L3 function. In addition, the upper node 10 simultaneously performs the control function of the radio frequency node 20. The radio frequency node 20 and its upper node 10 form one end of a wireless communication system and wirelessly communicate with the other end of the wireless transceiver 30.

It should be noted that the specific embodiment of the upper node 10, the radio frequency node 20, and the wireless transceiver 30 is not limited in the embodiment of the present invention. For example, the upper node 10 may be a BBU, the radio node 20 may be an RRU, and the wireless transceiver 30 may be a terminal or a transit base station or the like.

As shown in FIG. 1 and FIG. 2, the radio frequency node 20 communicates with the upper node 10 via the transmission system 40.

Here, the transmission system may also be referred to as a transmission network, and the embodiment of the present invention does not specifically limit the transmission network. For example, the transmission network may be Time Division Multiplexing (Time Division Multiplexing, TDM) network, or it can be a packet network or the like.

The embodiment of the present invention does not limit the transmission mode between the radio frequency node 20 and the wireless transceiver 30, and may be, for example, a cellular network, a microwave network, a point-to-point transmission, or a wifi.

As an architecture, as shown in FIG. 1, the radio node 20 communicates with the upper node 10 for the wireless service bottom layer 51, and the transport layer 50 carries the wireless service bottom layer 51. The radio service node 20 communicates with the wireless transceiver 30 for the wireless service upper layer 53. The wireless service bottom layer 51 between the upper node 10 and the radio frequency node 20 and the wireless service bottom layer 252 between the radio frequency node 20 and the wireless transceiver 30 are segmented. Hosted.

As another architecture, as shown in FIG. 2, the upper node 10, the radio frequency node 20, and the wireless transceiver 30 perform wireless service layer 54 communication, and the upper node 10 and the radio frequency node 20 and the radio frequency node 20 communicate with each other. The device 30 is segmented and carried.

In the embodiment of the present invention, the transmission quality monitoring is performed on the transmission layer 50 between the upper node 10 and the radio frequency node 20, and then the wireless service bottom layer 51 and the wireless service upper layer 53 or the wireless service layer 54 are protected.

3 is a flow chart of a method of data transmission in accordance with an embodiment of the present invention. The method shown in Figure 3 includes:

S301. Determine a transmission quality between the radio frequency node and the upper node.

S302. Adjust, according to the transmission quality, a transmission rate of a wireless service carried between the radio frequency node and the upper-level node.

In the embodiment of the present invention, the method shown in FIG. 3 is mainly performed by an upper node. In S301, the radio frequency node may monitor the transmission quality and notify the superior node. That is to say, S301 may be that the upper node obtains the transmission quality obtained by the radio node from the radio node.

Specifically, S301 may include: determining the transmission quality parameter according to transmission information of a transmission system between the radio frequency node and the upper node. The transmission quality parameter may include at least one of the following: a packet loss rate, a bit error rate, a jitter, and a delay. That is, the assessment of transmission quality can be evaluated based on one or more of the packet loss rate, bit error rate, jitter, and delay.

Here, the transmission quality parameter may also include other transmission parameters, which are not limited herein. For example, the transmission quality parameters may include transmission of available bandwidth and the like. The evaluation criteria for the transmission quality parameter can be preset A fixed value is also set, which may be a parameter value measured at a previous moment of the current time, which is not limited herein.

In this way, the change in transmission quality can be determined based on changes in the transmission quality parameters.

Further, in S302, when the transmission quality increases, the transmission rate of the wireless service is increased; or the wireless modulation order is increased to increase the transmission rate of the wireless service. When the transmission quality is degraded, the transmission rate of the wireless service is reduced; or the transmission rate of the wireless service is increased by reducing the wireless modulation order.

Optionally, if the wireless service is prioritized, the low priority service may also be flow controlled based on the transmission quality in S302.

For example, it is assumed that the wireless service includes a first wireless service with a priority of 1 and a second wireless service with a priority of 2, that is, the first wireless service has a higher priority than the second wireless service. Then, when the transmission quality is degraded, the transmission rate of the second wireless service can be lowered in order to preferentially guarantee the transmission of the first wireless service. For example, the transmission rate of the second wireless service can be reduced by 50%.

It can be seen that, in this embodiment, the service capability of the wireless layer can be improved by adjusting the transmission rate of the wireless service. By adopting the method shown in this embodiment, the quality requirement for the transmission network can be reduced, thereby reducing the transmission cost, and further improving the technical feasibility of the transmission.

Optionally, as an embodiment, the base station may provide multiple cells, that is, the radio frequency node 20 may access multiple cells at the same time. As shown in FIG. 4, the first radio frequency node 21 and the second radio frequency node 22 are included in FIG. In the embodiment shown in FIG. 4, one radio frequency node (the first radio frequency node 21 or the second radio frequency node 22) may simultaneously access the first cell 61 and the second cell 62. It is also possible that the first radio frequency node 21 accesses the first cell 61 and the second radio frequency node 22 accesses the second cell 62.

At this time, the wireless transceiver 30 accesses the wireless system through a plurality of cells (such as the first cell 61 and the second cell 62 in FIG. 4). The wireless transceiver 30 can simultaneously send and receive data through multiple cells. For example, each cell can correspond to one data stream.

In a scenario similar to that of Figure 4, transmission system 40 can carry information for the cell. Then, it can be understood that the transmission quality related to the cell can be determined in S301, and then the transmission rate of the wireless service of the corresponding cell is adjusted in S302. The transmission rate of the radio service of the corresponding cell may be understood as the transmission rate of the data stream of the corresponding cell.

Taking the first cell as an example, the transmission quality associated with the first cell may be determined according to a transmission quality parameter of the transmission system between the radio node and the upper node. And adjusting, according to the transmission quality associated with the first cell, a transmission rate of the wireless service related to the first cell carried by the radio frequency node and the upper-level node. That is, the transmission rate of the data stream corresponding to the first cell is adjusted.

If the one or more of the packet loss rate, the error rate increase, the jitter increase, and the delay increase corresponding to the first cell in the transmission system are detected, the first cell may be determined. The associated transmission quality is degraded. If one or more of a packet loss rate, a bit error rate reduction, a jitter reduction, and a delay reduction corresponding to the first cell in the transmission system are detected, the first cell may be determined. The transmission quality has increased.

Among them, the transmission rate of the wireless service can be adjusted by adjusting the wireless modulation order. For example, when the transmission quality associated with the first cell increases, the transmission rate of the wireless service related to the first cell is increased, or the transmission rate of the wireless service related to the first cell is increased by increasing the wireless modulation order. For example, when the transmission quality associated with the first cell decreases, the transmission rate of the wireless service associated with the first cell is reduced, or the transmission rate of the wireless service associated with the first cell is reduced by lowering the degree of wireless modulation.

It can be seen that, in this embodiment, the service capability of the radio layer of the corresponding cell can be improved by adjusting the transmission rate of the radio service of the corresponding cell. By adopting the method shown in this embodiment, the quality requirement for the transmission network can be reduced, thereby reducing the transmission cost, and further improving the technical feasibility of the transmission.

Optionally, the transmission quality related to the multiple cells may be determined in S301, and the amount of data between the multiple cells is further adjusted in S302 to adjust the transmission rate of the wireless service.

For example, the transmission quality associated with the first cell and the transmission quality associated with the second cell may be determined according to a transmission quality parameter of the transmission system between the radio frequency node and the superior node. When the transmission quality associated with the second cell is better than the transmission quality associated with the first cell, the data of the first cell is handed over to the second cell for transmission.

It should be noted that the cell-related transmission quality may be determined by the upper-level node; or the radio-frequency node may also monitor the cell-related transmission quality, and the radio-frequency node notifies the super-node of the monitored transmission quality and the identity of the corresponding cell.

For example, the higher priority data originally transmitted in the first cell may be switched to the second cell to ensure the transmission rate of the higher priority data. Understandably, the controller or administrator can set a higher priority for more important data.

It can be understood that the data of the first cell is switched to the second cell for transmission. The purpose of reducing the transmission rate in the first cell and increasing the transmission rate in the second cell.

At the same time, the method further includes: allocating data with high priority to be transmitted subsequently to the second cell for transmission. For example, the superior node allocates the data with high priority that is planned to be transmitted by the first cell to the second cell for transmission, so as to ensure the transmission rate of the data with high priority.

That is to say, when the upper node allocates data, it can allocate important data with high priority to the cell with good transmission quality.

After the subsequent transmission quality associated with the first cell is improved, the data switched to the second cell may be switched back.

In the embodiment of the present invention, the wireless service in S302 may be a wireless service under the wireless service or a wireless service at a high level of the wireless service, as shown in FIG. 1 . Or the wireless service in S302 may also be a wireless service of the wireless service layer, as shown in FIG. 2 .

It should be noted that the method of the embodiment of the present invention may also be a radio layer compression technology based on transmission quality. Or it can be applied to the transport layer, such as transmission quality based compression and multiplexing techniques. The invention is not limited thereto.

When one or more items are used, it can be determined that the transmission quality is degraded. When one or more of a packet loss rate reduction, a bit error rate reduction, a jitter reduction, and a delay reduction are detected, it is possible to determine that the transmission quality is increased.
