Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a wireless communication system and method. Background Art

[0002] The current mobile network adopts a cellular layout, that is, one base station serves multiple user terminals, forming a 1:N network architecture. At the air interface level, the control plane and the data plane share the same frequency and are organized according to a specific structure. With the growing demand for the Internet of Everything, future mobile networks will put forward higher timeliness and accuracy requirements for the signaling scheduling of the control plane, while the data plane needs to support higher transmission rates and greater capacity. However, since the control plane and the data plane share the same frequency band, during the peak period of data services, data plane activities significantly interfere with the control plane, affecting the network's service quality. As mobile communication technology evolves towards high speed, large capacity, and low latency, the next-generation 6G network plans to use the large-bandwidth terahertz frequency band for communication. However, high-frequency band signals face the problem of weak refraction, diffraction, and reflection capabilities, which limits the effectiveness of mobile communications in complex wireless environments and becomes a major challenge for future development.

It should be noted that, during the process of the macro base station resending the second service data, if the second time-frequency domain resources and the second modulation and demodulation method change, the second notification message needs to be resent.

[0063] When an upper layer network (such as a core network) has a new data service packet that needs to be sent to a second mobile terminal within the signal coverage of a small base station under a macro base station, the interactive transmission process can be performed in the following manner:

The third time-frequency domain resource and the third modulation and demodulation method are used to send the third service data to the second mobile terminal; the second mobile terminal is used to receive the third service data from the second data transmission link; when the reception is successful, the third confirmation message is sent to the macro base station through the second signaling transmission link; when the reception fails, the third non-confirmation message is sent to the macro base station through the second signaling transmission link; the macro base station is also used to send the first retransmission message to the target small base station through the preset transmission link when the third non-confirmation message is received, or when the third confirmation message is not received after a preset period of time; the target small base station is also used to respond to the first retransmission message and re-send the third service data to the second mobile terminal through the second data transmission link. It should be noted that during the process of the target small base station resending the third service data, if the third time-frequency domain resource and the third modulation and demodulation method change, the macro base station needs to resend the third notification message.

[0065] For example, after the macro base station receives the downlink data service packet to be sent to the second mobile terminal (MS2) from the upper layer network, that is, the third service data, the macro base station transmits the data according to the uplink signaling transmission link based on the first frequency. The downlink channel quality in the second measurement report (MR) reported by MS2 is received, and the busy and idle status of the third time-frequency domain resources of the target small base station (Smcell1) is selected, and the third time-frequency domain resources (denoted as RB) required for the downlink data of MS2 are calculated. 下行 resource ), the macro base station transmits a downlink signaling link based on the first frequency Notify MS2 about the RB used for downlink data service packet transmission in this cycle 下行 resource and the modulation and demodulation mode, that is, the third modulation and demodulation mode, and the third service data, RB 下行 resource The third modulation and demodulation mode is sent to Smcell1; MS2 transmits data in the downlink data transmission link based on the second frequency RB 下行 resource After receiving the corresponding third service data, Send a third confirmation message (ACK) or a third non-confirmation message (NACK) to the macro base station to inform the macro base station of the success or failure of receiving the downlink data service packet in this cycle. If MS2 RB 下行 resource After receiving the corresponding downlink data, Send a NACK message to the macro base station to start retransmission of the downlink data service packet in this cycle. The macro base station notifies Smcell1. RB 下行 resource resends the downlink data service packet within this period; if the macro base station does not receive the downlink data service packet sent by MS2 within the preset period If an ACK message or NACK message is sent, it is determined that the downlink data service packet in this cycle has not been received successfully, and the retransmission of the downlink data service packet in this cycle is started. The macro base station notifies Smcell1. RB 下行 resource Retransmit the downlink data service packets within this period.

[0066] The above message transmission process can be summarized as follows:

[0067] S31, the second mobile terminal sends a second measurement report to the macro base station;

[0068] S32, the macro base station sends third service data to the target small base station, and the macro base station sends a third notification message to the second mobile terminal;

[0069] S33, the target small base station sends third service data to the second mobile terminal;

[0070] S341, the second mobile terminal receives successfully and sends a third confirmation message to the macro base station;

[0071] S342, the second mobile terminal fails to receive and sends a third non-confirmation message to the macro base station;

[0072] S35, the macro base station receives the third non-confirmation message or does not receive the third confirmation message within the preset time period, and sends a first retransmission message to the target small base station;

[0073] S36, the target small base station re-sends the third service data to the second mobile terminal.

[0074] When the second mobile terminal has data to upload, the interactive transmission process can be performed in the following manner:

[0075] Optionally, the second mobile terminal is used to send a second upload application message to the macro base station via a second signaling transmission link, wherein the second upload application message includes the data volume of the fourth service data to be uploaded; the macro base station is used to respond to the second upload application message, obtain the fourth time-frequency domain resource status of the target small base station corresponding to the second mobile terminal, determine the fourth time-frequency domain resources and fourth modulation and demodulation mode for transmitting the fourth service data according to the fourth time-frequency domain resource status and the second channel quality information, send the fourth time-frequency domain resources and the fourth modulation and demodulation mode to the target small base station via a preset transmission link, and send a fourth notification message to the second mobile terminal via the second signaling transmission link, wherein the fourth notification message includes the fourth time-frequency domain resources and the fourth modulation and demodulation mode mode; the second mobile terminal is used to send the fourth service data to the target small base station on the second data transmission link according to the fourth time-frequency domain resources and the fourth modulation and demodulation mode; the target small base station is used to receive the fourth service data from the second data transmission link; when the reception is successful, the fourth confirmation message is sent to the macro base station through the preset transmission link; when the reception fails, the fourth non-confirmation message is sent to the macro base station through the preset transmission link; the macro base station is also used to send the second retransmission message to the second mobile terminal through the second signaling transmission link when the fourth non-confirmation message is received, or when the fourth confirmation message is not received after a preset period of time; the second mobile terminal is also used to respond to the second retransmission message and re-send the fourth service data to the target small base station through the second data transmission link. It should be noted that in the process of resending the fourth service data, if the fourth time-frequency domain resources and the fourth modulation and demodulation mode change, the macro base station needs to resend the fourth notification message.

[0076] For example, when MS2 needs to transmit an uplink data service packet in this cycle, MS2 transmits the uplink data packet through the second signaling uplink transmission link. The macro base station sends a second upload application message to the macro base station, including the size of the uplink data service packet; after receiving the second upload application message about MS2, the macro base station reports the channel quality and RB 上行 Resource busy and idle conditions, select the fourth modulation and demodulation mode and RB 上行 resource At the same time, Smcell1 is notified through the transmission link, and the second signaling downlink transmission link is used The uplink data service packet transmission scheduling message is transmitted to MS2; after MS2 receives the uplink data service packet transmission scheduling message from the macro base station, RB specified on 上行 resource The specified modulation and demodulation mode is adopted to transmit the uplink data service packet to Smcell1; after Smcell1 receives the uplink data service packet message of MS2 in this cycle, it transmits the uplink data service packet to Smcell1 through the macro base station. The ACK / NACK message is transmitted to MS2. In particular, if the RB used for the uplink data service packet transmission in this cycle is 上行 resource The modulation and demodulation mode is the same as the previous cycle, and the macro base station does not need to pass Inform MS2.

[0077] The above message transmission process can be summarized as follows:

[0078] S41, the second mobile terminal sends a second upload application message to the macro base station;

[0079] S42, the macro base station sends a fourth notification message to the second mobile terminal;

[0080] S43, the second mobile terminal sends fourth service data to the target small base station;

[0081] S441, when receiving successfully, the target small base station sends a fourth confirmation message to the macro base station;

[0082] S442, when reception fails, the target small base station sends a fourth non-confirmation message to the macro base station;

[0083] S45, the macro base station receives a fourth non-confirmation message or does not receive a fourth confirmation message within a preset time period, and sends a second retransmission message to the second mobile terminal;

[0084] S46, the second mobile terminal re-sends the fourth service data to the target small base station.

[0085] Considering the characteristics of data transmission and feedback, the data service and the corresponding ACK\NACK message can be synchronized or asynchronous.

[0086] The macro base station is also used to periodically receive measurement reports reported by the target mobile terminal. When the first base station identifier in the currently received measurement report is different from the second base station identifier in the last received measurement report, it is determined that the target mobile terminal has moved to the signal coverage range of the first base station corresponding to the first base station identifier, and the first base station is scheduled to perform data plane data transmission with the target mobile terminal, wherein the target mobile terminal includes: the first mobile terminal or the second mobile terminal, and the first base station includes: a macro base station or any small base station.

In this way, different frequencies are allocated to control plane signaling and data plane data (the first frequency is used for control plane signaling, and the second and fourth frequencies are used for data plane data), which reduces mutual interference between the two, and different frequency transmissions are adopted in macro base stations, small base stations, and mobile terminals. Through reasonable planning and use of different frequency resources, faster data transmission, lower latency and more stable network connections can be achieved, thereby solving the technical problem that the data plane data of the same frequency seriously interferes with the control plane signaling due to the influence of wireless frequency characteristics in the communication system.
