The method for uplink data transmission provided in the embodiment of the present application may be applied to a communication system as shown in fig. 3, where the communication system may include at least one base station 10 (only 1 is shown in the figure) and one or more terminals 20 capable of communicating with the base station 10.
The base station is mainly used for realizing wireless physical layer functions, resource scheduling and wireless resource management, wireless access control and mobility management functions;
the terminal, which may also be referred to as a User Equipment (UE), includes: a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a smart phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite radio, a wireless modem card, a Customer Premises Equipment (CPE), and/or other devices for communicating over a wireless system. It should be noted that the terminal in the embodiment of the present application may be a terminal that supports uplink data transmission through only one uplink, or may be a terminal that supports uplink data transmission through two uplinks simultaneously.
It should be noted that fig. 3 is only an exemplary architecture diagram, and in addition to the functional units shown in fig. 1, other functional units may be included in the communication system, which is not limited in this embodiment of the present application.
Based on the scenario shown in fig. 2 and the communication system shown in fig. 3, an embodiment of the present application provides a method for uplink data transmission, and as shown in fig. 4, the method includes: step 401 to step 403.
Step 401, the base station determines a target uplink of the terminal according to the capability information of the terminal, the transmission performance parameter of the first uplink and the transmission performance parameter of the second uplink.
Wherein the frequency of the first uplink is greater than the frequency of the second uplink. The first uplink may be an uplink having the same frequency as a downlink in a Time Division Duplexing (TDD) system, or an uplink corresponding to an uplink frequency symmetrical to a downlink frequency in a Frequency Division Duplexing (FDD) system. The second uplink is a supplementary uplink added on the basis of the first uplink after the SUL technology is adopted. Illustratively, the first uplink may be a UL link and the second uplink may be a SUL link.
The capability information of the terminal is used to indicate that the terminal supports uplink data transmission on one uplink (i.e., the terminal cannot simultaneously perform uplink data transmission on multiple uplinks, which may be referred to as single-shot), or the capability information of the terminal is used to indicate that the terminal supports simultaneous uplink data transmission on two uplinks (which may be referred to as double-shot). Illustratively, the capability information of the terminal may be represented by bits, for example, if the capability information of the terminal is 0, it indicates that the terminal supports single-shot transmission, and if the capability information of the terminal is 1, it indicates that the terminal supports double-shot transmission.
The transmission performance parameter includes at least one of an uplink signal quality, a transmission rate, and a transmission load.
The Signal quality includes at least one of Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR). The larger the RSRP is, the better the uplink signal quality is; the larger the RSRQ, the better the uplink signal quality; the larger the SINR, the better the uplink signal quality.
The transmission rate is an average rate at which data traffic is transmitted on one uplink for a certain period.
The transmission load is Physical Resource Block (PRB) occupancy of an uplink, that is, a ratio of the number of PRBs that have been used for uplink data transmission to the total number of PRBs of the uplink.
The base station may determine the weight of the first uplink and the weight of the second uplink according to the transmission performance parameter of the first uplink and the transmission performance parameter of the second uplink. It can be understood that the larger the weight of the uplink, the stronger the data transmission capability representing the uplink. The weight of the uplink is related to the transmission performance parameter of the uplink, and for example, if the transmission performance parameter includes uplink signal quality, transmission rate and transmission load, the better the uplink signal quality, the larger the transmission rate, the smaller the transmission load, and the larger the weight of the uplink.
The present application does not limit the method for determining the weight of the first uplink and the weight of the second uplink, and for example, the embodiments of the present application provide a possible method for calculating the weight of the uplink, which is applicable to the first uplink and the second uplink. The weight of the uplink is α signal quality factor + β transmission rate factor + γ transmission load factor.
Wherein, α, β, γ are preset weight coefficients, the value range is 0 to 1, and α + β + γ is 1;
the values of the signal quality factor, the transmission rate factor and the transmission load factor can be respectively determined based on the values of the uplink signal quality, the transmission rate and the transmission load, and the better the uplink signal quality is, the larger the signal quality factor is; the greater the transmission rate, the greater the transmission rate factor; the smaller the transmission load, the larger the transmission load factor. Exemplarily, if the uplink signal quality is represented by RSRP, if RSRP ≦ P1, the signal quality factor is N1; if P1< RSRP ≦ P2, the signal quality factor is N2; if P2< RSRP ≦ P3, the signal quality factor is N3; wherein, P1, P2, P3 are preset threshold values, and N1, N2, N3 are values of the signal quality factor. For example, P1 ≦ 110dBm, P2 ≦ -100dBm, P3 ≦ -90dBm, and if RSRP ≦ -110dBm, the signal quality factor may be 0; if-110 dBm < RSRP less than or equal to-100 dBm, the signal quality factor is equal to 1; and if the RSRP is less than-100 dBm and less than-90 dBm, the signal quality factor is equal to 2. The determination method of the transmission rate factor and the transmission load factor is similar to the determination method of the uplink signal quality factor, and is not illustrated here one by one, and of course, other methods may also be used to determine the uplink signal quality factor, the transmission rate factor, and the transmission load factor in the embodiments of the present application, which is not limited in the present application.
The target uplink is a link selected by the base station from the first uplink and the second uplink for uplink data transmission.
The base station specifically determines the target uplink by the following three situations:
the first situation is as follows: and if the difference value between the weight value of the first uplink and the weight value of the second uplink is greater than or equal to a preset threshold, the base station determines that the target uplink is the uplink with the higher weight value in the first uplink and the second uplink.
Specifically, if the difference between the weight of the first uplink and the weight of the second uplink is greater than or equal to the preset threshold, the base station determines that the target uplink is the first uplink.
If the difference between the weight of the first uplink and the weight of the second uplink is greater than or equal to the preset threshold, it is indicated that the data transmission capability of the first uplink is far greater than the data transmission capability of the second uplink, so if the capability information of the terminal is single-shot, it may be determined that the target uplink is the first uplink. In this case, if the capability information of the terminal is dual-transmission, if the terminal performs uplink data transmission by using both the first uplink and the second uplink, the performance gain is not obvious compared with that of performing uplink data transmission by using only the first uplink, and the base station needs to combine uplink data received from the two uplinks, the processing complexity of the base station may be increased, which may cause an increase in uplink data processing delay.
And if the difference value obtained by subtracting the weight value of the first uplink from the weight value of the second uplink is greater than or equal to a preset threshold, the base station determines that the target uplink is the second uplink.
If the difference between the weight of the second uplink and the weight of the first uplink is greater than or equal to the preset threshold, it is indicated that the data transmission capability of the second uplink is far greater than the data transmission capability of the first uplink, so if the capability information of the terminal is single-shot, it may be determined that the target uplink is the second uplink. In this case, if the capability information of the terminal is dual-transmission, referring to the description of the case one, in order to reduce the processing complexity of the base station while improving the uplink transmission performance, the second uplink may be taken as the target uplink.
Case two: if the terminal supports uplink data transmission on at least two different uplink links at the same time, and the difference value between the weight value of the first uplink link and the weight value of the second uplink link is smaller than a preset threshold, the base station determines that the target uplink link is the first uplink link and the second uplink link.
It can be understood that, if the difference between the weight of the first uplink and the weight of the second uplink is smaller than the preset threshold, which indicates that the difference between the data transmission capabilities of the first uplink and the second uplink is not large, and the terminal simultaneously uses the first uplink and the second uplink for uplink data transmission, so that the uplink data transmission efficiency of the terminal can be improved.
Case three: if the terminal only supports uplink data transmission on one uplink and the difference value between the weight of the first uplink and the weight of the second uplink is smaller than a preset threshold, the base station determines that the target uplink is the uplink with the larger weight in the first uplink and the second uplink.
Step 402, the base station sends a first message to the terminal.
Accordingly, the terminal receives the first message.
The first message carries target uplink information, a base station identifier and a terminal identifier. Alternatively, the target uplink information may be an identification of the target uplink.
The first message may be an uplink transmission control message, and the base station may reuse an existing RRC message, such as an RRC connection reconfiguration message, or may define a new Radio Resource Control (RRC) message as the first message.
And step 403, the terminal performs uplink data transmission through the target uplink.
It can be understood that, if the target uplink information received by the terminal indicates a first uplink, the terminal performs uplink data transmission through the first uplink; if the target uplink information received by the terminal indicates a second uplink, the terminal transmits uplink data through the second uplink; and if the target uplink information received by the terminal indicates a first uplink and a second uplink, the terminal performs uplink data transmission in parallel through the first uplink and the second uplink.
According to the uplink data transmission method provided by the embodiment of the application, the base station can determine the target uplink according to the capability information of the terminal, the transmission performance parameter of the first uplink and the transmission performance parameter of the second uplink, and further instruct the terminal to perform uplink data transmission through the target uplink.
Based on the embodiment shown in fig. 4, if the target uplink is the first uplink and the second uplink, the base station may further determine the ratio of the uplink data transmitted by the first uplink and the second uplink, and based on this, in another implementation manner provided by the embodiment of the present application, as shown in fig. 5, the method includes steps 501 to 507.
Step 501, the base station configures a first uplink and a second uplink.
The first uplink may be a New Radio (NR) UL link, and the second uplink may be a SUL link. The description of the first uplink and the second uplink may refer to the related description in step 401, and is not repeated here.
Step 502, the base station sends a capability query message to the terminal.
Accordingly, the terminal receives a capability query message from the base station.
The capability query message is used for indicating the terminal to report capability information. Alternatively, the base station may reuse an existing RRC message as a capability query message, for example, a UE capability query message, or the base station may define a new RRC message as the capability query message.
Optionally, the capability query message carries a base station identifier and a terminal identifier.
Step 503, the terminal sends a capability reporting message to the base station.
Accordingly, the base station receives the capability reporting message from the terminal.
The capability reporting message includes capability information, and the related description in step 401 may be referred to for the capability information of the terminal, which is not described herein again.
Optionally, the capability reporting message further carries a base station identifier and a terminal identifier.
The terminal may reuse an existing RRC message as a capability reporting message, such as a UE capability information message, or the terminal may define a new RRC message as the capability reporting message.
Step 504, the base station obtains the transmission performance parameter of the first uplink and the transmission performance parameter of the second uplink.
Wherein, the transmission performance parameter includes at least one of uplink signal quality, transmission rate and transmission load.
The base station may determine the uplink signal quality of the first uplink and the uplink signal quality of the second uplink by measuring the uplink reference signal of the first uplink and the uplink reference signal of the second uplink, respectively.
Alternatively, the base station may determine the transmission rate of the first uplink by counting the average rate of the data traffic of the first uplink in the specified period, and determine the transmission rate of the second uplink by counting the average rate of the data traffic of the second uplink in the specified period.
Alternatively, the base station may determine the transmission load of the first uplink by counting the PRB occupancy of the first uplink, and determine the transmission load of the second uplink by counting the PRB occupancy of the second uplink.
And 505, the base station determines the target uplink and uplink data allocation ratio according to the capability information of the terminal, the transmission performance parameter of the first uplink and the transmission performance parameter of the second uplink.
For the method for determining the target uplink by the base station, reference may be made to the related description in step 401, and details are not repeated here.
Optionally, if the target uplink determined by the base station is the first uplink or the second uplink, the base station may not determine the uplink data allocation ratio; if the base station determines that the target uplink is the first uplink and the second uplink, the base station may further determine the uplink data allocation ratio.
The base station may determine an uplink data allocation ratio according to the weight of the first uplink and the weight of the second uplink, where the uplink data allocation ratio is a ratio of an amount of uplink data allocated to the first uplink to an amount of uplink data allocated to the second uplink, and the uplink data allocation ratio is equal to the ratio of the weight of the first uplink to the weight of the second uplink. That is, the uplink data allocation ratio is the uplink data amount of the first uplink allocation/the uplink data amount of the second uplink allocation is the weight of the first uplink/the weight of the second uplink. For example, if the ratio of the weight value of the first uplink to the weight value of the second uplink is 1/3, the uplink data allocation ratio is 1/3, which represents that the terminal transmits uplink data 1/4 via the first uplink and uplink data 3/4 via the second uplink.
Step 506, the base station sends a first message to the terminal.
Accordingly, the terminal receives a first message from the base station.
The first message includes information of a target uplink, a base station identifier and a terminal identifier. Optionally, the first message further includes an uplink data allocation proportion.
The first message may be an uplink transmission control message, and the base station may reuse an existing RRC message, such as an RRC connection reconfiguration message, or may define a new RRC message as the first message.
And step 507, the terminal transmits uplink data according to the target uplink and/or uplink data distribution proportion.
Optionally, if the target uplink is the first uplink, the terminal transmits uplink data through the first uplink; if the target uplink is a second uplink, the terminal transmits uplink data through the second uplink; if the target uplinks are the first uplink and the second uplink, the terminal transmits uplink data in parallel through the first uplink and the second uplink, and the data amount transmitted on the first uplink and the second uplink is determined according to the uplink data distribution ratio.
In the uplink data transmission method provided by the embodiment of the application, if the terminal supports single-shot transmission, the base station selects an uplink with good transmission performance as a target uplink of the terminal, if the terminal supports double-shot transmission and the difference between the weights of the two uplinks is smaller than a preset value, the terminal can simultaneously transmit uplink data through the two uplinks, and the base station determines an uplink data allocation ratio according to transmission performance parameters of the first uplink and the second uplink, so that the terminal can transmit uplink data in parallel by using the first uplink and the second uplink according to the uplink data allocation ratio, transmit more uplink data by using the uplink with good transmission performance, transmit less uplink data by using the uplink with poor transmission performance, make the terminal fully utilize the transmission capability of each uplink, and avoid allocating too much uplink data for the uplink with poor transmission performance, the uplink data transmission performance of the terminal can be improved, and the problems of transmission errors, transmission delay increase or congestion and the like of an uplink are avoided.
