Figure 1 shows, by way of example, a communication system 100 in one embodiment of the present invention. Pass The signaling system 100 includes at least one base station 102 and one or more terminals 104 in data communication with the base station 102. For example, communication system 100 can be located in a GERAN network, and of course, can also be located in other communication networks.

For example, base station 102 can be a base station located in a GERAN network, and base station 102 can communicate with one or more terminals 104.

For example, terminal 104 can receive or transmit wireless signals with a wireless communication device or network. For example, the terminal can be a radio device, a cellular telephone device, a computing device, a personal communication system device, or any other device that is equipped with wireless communication.

The data transmitted from the terminal 104 to the base station 102 may be referred to as an uplink signal, the channel on which the uplink signal transmitted by the terminal 104 to the base station 102 may be referred to as an uplink channel, and the data transmitted from the base station 102 to the terminal 104 may be referred to as a downlink signal, the base station The channel on which the downlink signal transmitted by the terminal 104 is located may be referred to as a downlink channel.

In the communication system 100, a time slot having the same slot number on consecutive frames of one frequency point can constitute one radio block.

If the communication system 100 is in the packet domain, the base station 102 uses the dynamic scheduling mode when scheduling the radio block resources, that is, the uplink channel and the USF that the network designating terminal uses for transmitting, and then sets the USF in the downlink data block. The terminal is instructed to send uplink data in the next radio block period of the uplink channel.

A method of resource scheduling is provided in one embodiment of the invention. As shown in Figure 2, the method includes the following sections.

The first terminal acquires the first training sequence indication information and the first uplink state identifier, where the training sequence of the first terminal indicated by the first training sequence indication information is different from the training sequence of other terminals scheduled by the first uplink state identifier. The first uplink state identifier is used to schedule the first terminal and other terminals to send data on the uplink radio block corresponding to the first uplink state identifier. There may be multiple ways for the first terminal to obtain the first training sequence indication information and the first uplink state identifier. For example, the first training sequence indication information and the first uplink state identifier may be pre-configured in the first terminal, or the first training sequence indication information and the first uplink state identifier may also be sent by the base station to the first terminal.

The training sequence of the first terminal indicated by the first training sequence indication information is different from the training sequence of other terminals scheduled by the first uplink state identifier. Further, optionally, in another embodiment provided by the method, the first training sequence indication information indicates that the training sequence of the first terminal and the first uplink state identifier are scheduled by other terminals. The training search can be orthogonal to each other as much as possible, and correspondingly, the base station can be implemented to decode the data of the first terminal from the received data. Further, optionally, in another embodiment provided by the method, the first training sequence indication information indicates that the training sequence of the first terminal and the first uplink state identifier are scheduled by other terminals. The cross-correlation between training and search is as small as possible. For example, the absolute value of the cross-correlation coefficient is less than or equal to 0.8, for example, 0.1, 0.2, 0.3, 0.5, 0.7, and so on.

220. The first terminal receives scheduling information, where the scheduling information includes a first uplink state identifier. The scheduling information can come from, for example, a base station. The base station schedules the first terminal to send an uplink signal to the base station by transmitting scheduling information including the first uplink state identifier.

The first terminal sends the data on the uplink radio block corresponding to the first uplink state identifier by using the training of the first terminal indicated by the first training sequence indication information.

On the uplink radio block corresponding to the first uplink state identifier, the other terminal scheduled by the first uplink state identifier also sends data on the uplink radio block, and when the first terminal and other terminals send data, the corresponding terminal is used. The training sequence encodes the transmitted data, and then transmits the encoded data to the base station on the corresponding uplink radio block corresponding to the first uplink state identifier. After receiving the data, the base station uses the interference cancellation technology to decode the uplink radio block according to the training sequence indicated by the first training sequence indication information of the first terminal and the training sequence used by other terminals, and obtain the first terminal and other terminals respectively. The data.

The data sent by the first terminal on the uplink radio block corresponding to the first uplink state identifier may be service data, control signaling, or a mixture of the two. According to another embodiment of the present invention, in a method for resource scheduling, on the basis of the embodiment shown in FIG. 2, the first terminal may further receive pulse position indication information sent by the base station, where the pulse position indication information indicates The position of the pulse used by a terminal to transmit data in an upstream radio block and the number of pulses.

Since one uplink radio block can contain more than one pulse, for example 4 pulses. Therefore, the pulse position indication information needs to indicate the number and position of the pulses in the uplink radio block used by the first terminal.

Instructing the first terminal to use the number of pulses in an uplink radio block can be understood as: Since one uplink radio block can include one or more pulses, the first terminal can be instructed to use one or more of the uplink radio blocks. Pulses.

The location indicating that the first terminal uses the pulse in one uplink radio block can be understood as: since the first terminal can be instructed to use one or several pulses in one uplink radio block, if the first terminal is instructed to use a pulse, It is necessary to indicate to the first terminal that the first of the four pulses in an upstream radio block, for example, the first or second pulse. If the first terminal is instructed to use 2 pulses, it is required to indicate to the first terminal which of the 4 pulses in an uplink radio block, such as the first and second pulses or the third and fourth Pulses, etc. Correspondingly, the first terminal sends data on the uplink radio block corresponding to the first uplink state identifier, and the first terminal sends data on the pulse indicated by the pulse position indication information in the uplink radio block corresponding to the first uplink state identifier.

By using the pulse position indication information, the terminal can be more flexible when transmitting the uplink signal to the base station. When less data and/or signaling is sent, the number of pulses used can be reduced. When the number of used pulses is less than four, it is necessary to indicate which one of the four pulses or which two pulses the terminal uses. The four pulses of such a radio block can support more user terminals, improving the utilization of radio resources and the reuse rate of users.

Further, in the resource scheduling method provided by the further embodiment of the present invention, the first terminal may further obtain information about the second uplink state identifier, where the second uplink state is The identifier is used to uniquely schedule the first terminal in the second uplink The status identifier is sent on the corresponding uplink radio block. Further, the method for resource scheduling in a further embodiment of the present invention may further include: using, by the first terminal, the first indicated by the first training sequence indication information on the uplink radio block corresponding to the second uplink state identifier The training sequence of the terminal transmits data. Further, the method for resource scheduling in a further embodiment of the present invention may further include: acquiring, by the first terminal, second training sequence indication information, where the training sequence of the first terminal indicated by the second training sequence indication information is first The training sequence of the first terminal indicated by the training sequence indication information is different; the first terminal sends data in the training sequence indicated by the second training sequence indication information in the uplink radio block corresponding to the second uplink state identifier.

When the base station sends the scheduling information including the second uplink state identifier to the first terminal, the base station instructs the first terminal to send data on the uplink radio block corresponding to the second uplink state identifier, where the second uplink state identifier does not schedule other The terminal sends data on the uplink radio block corresponding to the second uplink state identifier. Therefore, when the base station performs the second uplink state identifier scheduling, the base station only receives the data sent by the first terminal in the uplink radio block corresponding to the second uplink state identifier, but when scheduling by using the first uplink state identifier, the base station may be in the The data sent by the first terminal and other terminals is received on the uplink radio block corresponding to the first uplink status identifier.

In this embodiment, the base station may use the second uplink state identifier in combination with the first uplink state identifier to flexibly schedule the terminal to send uplink data.

Further, for the first terminal, the uplink block that is scheduled by the first uplink state identifier and the uplink block that is used by the second uplink state to indicate scheduling may use different modulation and coding modes. The network can flexibly control the current radio condition and the number of uplink terminals sent on the uplink block corresponding to the first uplink state identifier to improve the reliability of the uplink transmission. For example, the first uplink state identifier has multiple terminals transmitting data on the uplink block, and the network may indicate that the first terminal uses a lower modulation and coding mode to reduce interference of other terminals, and the second uplink state identifier corresponds to the uplink block. Only when the first terminal is used, the network can instruct the first terminal to use a higher modulation and coding scheme. If only the first terminal sends data or signaling on the uplink block corresponding to the first uplink state identifier, and the other terminal does not send data or signaling, the network may instruct the first terminal to use a higher order modulation and coding mode. The flexible combination of the first and second uplink state identifiers can improve the uplink of the first terminal. Transmission rate.

Further, in the resource scheduling method provided by the further embodiment of the present invention, the first terminal may further receive the indication information of the data modulation and coding mode, based on the method embodiment of the resource scheduling shown in FIG. For example, the indication information indicates that the data modulation coding mode of the first terminal may include, for example, GMSK (Gaussian Minimum Shift Keying), 8PSK (8-Phased Shift Keying), QPSK (Quarature) Phase-shift keying, one of 16QAM (16-Quadrature amplitude modulation) and 32QAM (16-Quadrature amplitude modulation).

The first terminal performs corresponding processing and encoding on the data according to the acquired training sequence and the data modulation and coding mode indicated by the indication information, to obtain encoded data. The first terminal then transmits the encoded data to the base station. The base station decodes the encoded data according to the corresponding data coding mode and interference cancellation technique. Due to different data rates caused by different modulation and coding modes, the terminal is allowed to use different modulation and coding modes, which can flexibly increase the uplink data rate, and can adjust the uplink modulation and coding mode in time to ensure data transmission when the channel conditions fluctuate. Reliability.

Further, in another method for resource scheduling provided by the method in the present invention, the data modulation and coding mode received by the first terminal may be compared with the data modulation code received by other terminals scheduled by the first uplink state identifier. Different ways. In this way, the network can flexibly indicate that different terminals use different modulation and coding modes to transmit uplinks according to different modulation and coding capabilities of the terminal, and the multiple terminals of the first uplink state identifier are not mutually restricted, even if the first terminal only supports modulation such as GMSK. In other modes, other terminals can use a modulation mode such as 8PSK, which effectively improves the uplink bandwidth of terminals supporting higher modulation and coding capabilities.

As shown in FIG. 3, in an embodiment of the present invention, a terminal 400 is shown by way of example, and the terminal 400 can complete all functions of the first terminal in the foregoing method for resource scheduling. The terminal 400 can implement all the functions of the foregoing first terminal by using software and/or hardware. For example, the terminal 400 can include one or more processors to implement all the functions of the first terminal. For example, the terminal 400 may include an information acquisition unit 410, a scheduling information receiving unit 420, and a The sending unit 430.

The information acquiring unit 410 is configured to obtain the first training sequence indication information and the first uplink state identifier, where the training sequence indicated by the first training sequence indication information of the terminal 410 and the training sequence of other terminals scheduled by the first uplink state identifier are not Similarly, the first uplink state identifier is used to schedule the terminal 410 and the other terminals.

Further, optionally, in another embodiment provided by the method, the first training sequence indication information indicates that the training sequence of the first terminal and the first uplink state identifier are scheduled by other terminals. The training and searching can be orthogonal to each other as much as possible, and correspondingly, the base station can be implemented to decode the data of the first terminal from the received data. Further, optionally, in another embodiment provided by the method, the first training sequence indication information indicates that the training sequence of the first terminal and the first uplink state identifier are scheduled by other terminals. The cross-correlation between training and search is as small as possible. For example, the absolute value of the cross-correlation coefficient is less than or equal to 0.8, for example, 0.1, 0.2, 0.3, 0.5, 0.7, and so on.

The scheduling information receiving unit 420 is configured to receive scheduling information, where the scheduling information includes a first uplink state identifier.

The sending unit 430 is configured to send data on the uplink radio block corresponding to the first uplink state identifier, where the data may be service data or control signaling.

In another embodiment of the present invention, the information acquiring unit 410 is further configured to receive the pulse position indication information, where the pulse position indication information is used by the first terminal to send data in the uplink radio block corresponding to the first uplink state identifier. The position of the pulse.

The sending unit 430 sends the data on the uplink radio block corresponding to the first uplink state identifier, where the sending unit 430 sends the data on the pulse indicated by the pulse position indication information in the uplink radio block corresponding to the first uplink state identifier.

In another embodiment of the present invention, the information obtaining unit 410 is further configured to obtain indication information of a data modulation and coding manner. For example, the data modulation coding mode indicated by the indication information may include one of modulation modes such as GMSK, 8PSK, QPSK, 16QAM, and 32QAM. In still another embodiment of the present invention, the sending unit 430 is further configured to: encode the data to be sent by using a first modulation and coding manner to obtain encoded data, where the first modulation and coding mode is not used for the first The modulation coding mode used by the other terminal scheduled by the uplink state identifier to perform data coding; and the coded data is sent on the uplink radio block corresponding to the uplink state identifier.

The first terminal and the other terminals scheduled by the first uplink state identifier encode the data by using the training sequence orthogonal to each other, and then identify the data in the first uplink state by using the scheduling of the scheduling information of the first uplink state identifier. The corresponding uplink radio block is sent to the base station, and the base station can separately decode the data sent by the first terminal and other terminals to the base station from the received data. Therefore, when the first terminal sends the uplink signal, it can implement multiplexing with other terminals scheduled by the first uplink state identifier, improve the efficiency of the uplink transmission, and improve the uplink transmission efficiency while achieving an uplink state. The identity scheduling includes multiple terminals of the first terminal, and achieves dynamic scheduling of the wireless block on the uplink orthogonal subchannel without using the downlink orthogonal subchannel technology. In another embodiment of the invention, a method of resource scheduling is provided. As shown in Figure 4, the method includes the following sections.

510. The base station sends the first training sequence indication information corresponding to the first terminal, and the first uplink state identifier, where the training sequence indicated by the first training sequence indication information of the first terminal and the other terminal scheduled by the first uplink state identifier are The training sequence is different, and the first uplink state identifier is used to schedule the first terminal and the other terminal. The manner in which the base station obtains the first training sequence indication information and the first uplink state identifier of the first terminal may be multiple. For example, the first training sequence indication information and the first uplink state identifier of the first terminal may be saved on the base station, or the base station may also obtain the first training sequence indication information and the first uplink state identifier of the first terminal by receiving the message. . Further, optionally, in another embodiment provided by the method, the first training sequence indication information indicates that the training sequence of the first terminal and the first uplink state identifier are scheduled by other terminals. Training and searching can be orthogonal to each other as much as possible, correspondingly, The base station is configured to implement decoding of the data of the first terminal from the received data. Further, optionally, in another embodiment provided by the method, the first training sequence indication information indicates that the training sequence of the first terminal and the first uplink state identifier are scheduled by other terminals. The cross-correlation between training and search is as small as possible. For example, the absolute value of the cross-correlation coefficient is less than or equal to 0.8, for example, 0.1, 0.2, 0.3, 0.5, 0.7, and so on.

520. The base station sends scheduling information, where the scheduling information includes the first uplink state identifier. When the base station can send the scheduling information including the first uplink state identifier, the scheduling first terminal sends data on the uplink radio block corresponding to the first uplink state identifier. At the same time, the first uplink state identifier is used to schedule the first terminal and the other terminal to send data on the uplink radio block corresponding to the first uplink state identifier, so the base station may send the first uplink state identifier to the first terminal and the The other terminal schedules the first terminal and the other terminal to transmit data on the same radio block.

530. The base station receives data on an uplink radio block corresponding to the first uplink state identifier, where the data is service data or control data.

After receiving the scheduling information, the first terminal and the other terminal send data to the base station on the uplink radio block corresponding to the first uplink state identifier, as indicated by the first uplink state identifier in the scheduling information. Before the first terminal sends data on the uplink radio block, the data to be transmitted is code modulated using the training sequence indicated by the training sequence indication information of the first terminal. The other terminals scheduled by the first uplink state identifier can encode and modulate the data to be transmitted using their corresponding training sequences before transmitting the data.

540. The base station acquires data corresponding to the first terminal from the data by using a training sequence indicated by the first training sequence indication information.

The base station receives the data sent by the first terminal and the other terminal scheduled by the first uplink state identifier on the same uplink radio block, and uses the interference cancellation technology to decode the radio block according to the training sequence corresponding to the first terminal. Data, which can be obtained from the data of the wireless block The data of a terminal.

In this embodiment, the base station may schedule the first terminal and other terminals scheduled by the first uplink state identifier by sending the scheduling information that includes the first uplink state identifier, and indicate that the first terminal and other terminals are in the first uplink state identifier. Transmitting data on the corresponding uplink radio block, and decoding the data received on the uplink radio block according to the training sequence corresponding to the first terminal, and acquiring data corresponding to the first terminal from the uplink radio block . Therefore, it is implemented that the same uplink state identifier is used to schedule multiple terminals to transmit data on the corresponding radio block, thereby improving the efficiency of uplink transmission data.

In another embodiment provided by the exemplary embodiment of the present invention, the base station may further send pulse position indication information indicating that the first terminal is in an uplink wireless manner, based on the embodiment shown in FIG. The position of the pulse used to transmit data in the block and the number of pulses.

Since one uplink radio block can contain more than one pulse, for example 4 pulses. Therefore, the pulse position indication information needs to indicate the number and position of the pulses in the uplink radio block used by the first terminal. The number of the pulses in the uplink radio block used by the first terminal may be understood as: Since one uplink radio block may include one or more pulses, the first terminal may be instructed to use one of the uplink radio blocks. Or several pulses; indicating that the first terminal uses the position of the pulse in one uplink radio block can be understood as: since the first terminal can be instructed to use one or several pulses in one uplink radio block, if the first terminal is indicated A pulse is used, and it is required to indicate that the first terminal uses the first of the four pulses in an uplink radio block. If the first terminal is instructed to use 2 pulses, it needs to indicate that the first terminal is using Which of the four pulses in an upstream radio block, such as the first and second pulses or the third and fourth pulses, and the like. Correspondingly, the first terminal transmitting data on the uplink radio block corresponding to the first uplink state identifier may send data on the pulse indicated by the pulse location indication information in the uplink radio block corresponding to the first uplink state identifier.

The base station sends the pulse position indication information to the terminal, and the terminal can send the uplink signal. More flexible when given to the base station. When less data and/or signaling is sent, the number of pulses used can be reduced. When the number of used pulses is less than four, it is necessary to indicate which one of the four pulses or which two pulses the terminal uses. The four pulses of such a radio block can support more user terminals, improving the utilization of radio resources and the reuse rate of users.

In another embodiment of the present invention, which is provided by way of example, the base station may further send information about the second uplink state identifier, based on the foregoing method for performing resource scheduling on the base station side. The two uplink status identifiers are used to uniquely schedule the first terminal to send data on the uplink radio block corresponding to the second uplink status identifier.

Further, in the method for resource scheduling in the embodiment provided by the exemplary embodiment of the present invention, the base station may further send an indication of the data modulation and coding mode, based on the method embodiment of the resource scheduling shown in FIG. information. For example, the indication information indicates that the data modulation coding mode of the first terminal may include, for example, GMSK (Gaussian Minimum Shift Keying), 8PSK (8-Phased Shift Keying, 8 phase shift keying), QPSK (Quarature) Phase-shift keying, one of 16QAM (16-Quadrature amplitude modulation) and 32QAM (16-Quadrature amplitude modulation).

Correspondingly, the first terminal may perform corresponding processing and encoding on the data according to the data modulation and coding manner indicated by the received indication information, to obtain encoded data. Then, the first terminal will be encoded The data is sent to the base station on the uplink radio block corresponding to the first status identifier. The base station decodes the encoded data by using an interference cancellation technique according to the corresponding data coding mode. Since the data rates of different modulation and coding modes are different, the corresponding terminals are allowed to use different modulation and coding modes. Therefore, the base station can flexibly indicate the terminal to improve the uplink data transmission rate, and the base station can be timely when the channel conditions fluctuate. The terminal is notified to adjust the uplink modulation and coding mode to improve the reliability of the uplink data transmission.

Further, in the method for resource scheduling provided by the exemplary method of the present invention, the data modulation and coding mode of the other terminal that the base station indicates that the first state identifier is scheduled may be different from the data modulation and coding mode of the first terminal indicated by the base station. .

As shown in FIG. 5, an embodiment of the present invention shows, by way of example, a base station 600, which can perform all the functions of the base station in the foregoing method for resource scheduling. The base station 600 can implement all of the functions of the base station in software and/or hardware. For example, the base station 600 can include one or more processors to implement all of the functions of the base station. For example, the base station 600 can include a transmitting unit 620, a receiving unit 630, and a terminal data acquiring unit 640.

The sending unit 620 is configured to: obtain the first training sequence indication information corresponding to the first terminal, and the first uplink state identifier, where the training sequence indicated by the first training sequence indication information of the first terminal is related to the first uplink The training sequence of the other terminals scheduled by the state identifier is different, and the first uplink state identifier is used to schedule the first terminal and the other terminals.
