The Internet of Things (IoT) refers to the network that realizes the interconnection of people, things, objects and objects by deploying various devices with certain sensing, computing, execution and capacity to acquire information of the physical world and realize information transmission, coordination and processing through the network. . In other words, the Internet of Things is to achieve the interconnection of people and things, things and things. The Internet of Things can be applied to all aspects of intelligent networks, intelligent agriculture, intelligent transportation, and environmental monitoring.

The 3rd Generation Partnership Project (3GPP) of the Mobile Communications Standardization Organization proposed the Narrowband Internet of Things (NB-IoT). The NB-IoT has a bandwidth of 180 kHz and supports three deployment modes: Stand-alone operation, Guard band operation, and In-band operation.

Specifically, the independent mode is that the frequency band of LTE and the frequency band of NB-IoT are independent of each other. For example, as shown in FIG. 2, one or more carriers in a GSM network are used for NB-IoT transmission, and other one or more carriers are used for LTE transmission. The guard band mode is NB-IoT transmission using one or more resource blocks that are not utilized in the LTE carrier guard band. For example, as shown in FIG. 3, a guard band of at least one of the two ends of the LTE channel bandwidth may be used for NB-IoT transmission, wherein the LTE channel bandwidth includes a plurality of resource blocks, and each resource block has a bandwidth of 180 kHz. The in-band mode is to perform NB-IoT transmission using one or more resource blocks within the LTE channel bandwidth. For example, as shown in FIG. 4, one resource block in the LTE channel bandwidth is used for NB-IoT transmission, wherein the bandwidth of each resource block included in the LTE channel bandwidth is 180 kHz.

At present, the frequency division duplex (FDD) NB-IoT uplink supports the three-carrier bandwidth of 3.75 kHz and 15 kHz. The time slot is 2 ms for the 3.75 kHz subcarrier bandwidth and 0.5 ms for the 15 kHz subcarrier bandwidth.

For the compatibility of Time Division Duplex (TDD) NB-IoT and TDD LTE, it mainly involves the compatibility of uplink and downlink subframe configuration. Table 1 shows the uplink and downlink subframe configurations supported by TDD LTE. Wherein, each subframe is 1 ms, "D" represents a downlink subframe used for downlink transmission, "U" represents an uplink subframe for uplink transmission, and "S" represents a special subframe.

Table 1

It can be seen from Table 1 that the number of consecutive uplink subframes in the seven uplink and downlink subframe configurations of TDD LTE is one, two or 3

The TDD NB-IoT supports a 3.75 kHz subcarrier bandwidth, and for a 3.75 subcarrier bandwidth, when the time slot is 2 ms, the TDD NB-IoT can be compatible with two consecutive uplink subframes of two or three uplink and downlink subframes. . Specifically, the TDD NB-IoT can transmit uplink signals using a 3.75 kHz subcarrier bandwidth using two consecutive uplink subframes.

If the number of consecutive uplink subframes in the uplink and downlink subframe configuration is greater than two, that is, if the number of consecutive uplink subframes in the time domain is greater than two, the network device only schedules the terminal device. When the uplink transmission is performed using the 3.75 kHz subcarrier bandwidth, the utilization of the TDD NB-IoT uplink resource is reduced.

FIG. 5 shows a schematic flow chart of a method of signal processing in one embodiment of the present application.

Alternatively, the wireless communication system can be NB-IoT. The time domain configuration may specifically be an uplink and downlink subframe configuration.

Optionally, the subcarrier bandwidth supported by the wireless communication system includes a first subcarrier bandwidth.

It should be noted that the time domain configuration supported by the wireless communication system may be the same configuration as the uplink and downlink subframe configuration of the TDD LTE described above, or may be other uplink and downlink subframe configurations, and the application is not limited thereto.

Optionally, in the embodiment of the present application, the uplink time domain resource may be an uplink subframe or other time domain resource unit. For example, the uplink time domain resource may be an uplink radio frame, an uplink time slot, or an uplink symbol. For convenience of description, the above subframe is used as an example for description, but this application Not limited.

Optionally, in the embodiment of the present application, the first subcarrier bandwidth supported by the wireless communication system is 3.75 kHz as an example for description.

It should be understood that the subcarrier bandwidth is to divide the system bandwidth into any one of a plurality of frequency bands. For example, the first subcarrier bandwidth is 3.75 kHz, that is, the system bandwidth is divided into multiple 3.75 kHz subcarrier bandwidths.

501. The network device determines first indication information, where the first indication information is used to indicate a first target time domain unit in the at least two time domain units, where each of the at least two time domain units includes the At least two consecutive uplink time domain resources of the plurality of consecutive uplink time domain resources.

Specifically, the number of time domain units may be determined by the time domain configuration supported by the wireless communication system including the number of consecutive uplink time domain resources and the number of consecutive uplink time domain resources included in each time domain unit. For example, the time domain configuration supported by the wireless communication system includes three consecutive uplink time domain resources, and each time domain unit includes two consecutive uplink time domain resources, which is supported by the wireless communication system. When the domain configuration includes the three consecutive uplink time domain resources, there may be two time domain units, where the two time domain units respectively include the first two consecutive uplink time domain resources and the last two consecutive uplink time domains. Resources.

The first target time domain unit is one of the at least two time domain units. In addition, the same uplink time domain resource may be included in the at least two time domain units.

For example, in a case where the time domain configuration supported by the wireless communication system includes the three consecutive uplink time domain resources, it is assumed that three consecutive uplink time domain resources are marked as A, B, and C, and there may be two time domain units. The two time domain units respectively include the first two consecutive uplink time domain resources and the last two consecutive uplink time domain resources, for example, two time domain units may be AB, BC, respectively, and the two time domain units include one The same upstream time domain resource, such as B. The first target time domain unit may be one of the two time domain units, such as the first time domain unit being AB or the first time domain unit being BC.

Optionally, the plurality of consecutive uplink time domain resources may be 3 consecutive subframes.

Specifically, if the first subcarrier bandwidth is 3.75 kHz, and the time slot corresponding to the 3.75 kHz subcarrier bandwidth is 2 ms, and the uplink time domain resource is a subframe of 1 ms, the first two subframes constitute the first time domain unit, and then The two subframes form a second time domain unit, and the first indication information determined by the network device may be used to indicate that the first time domain unit is the first target time domain unit, or the second time domain unit is the first target time domain unit. . That is, the network device can determine the location of the resource for transmitting the uplink signal, so that the subframes other than the uplink signal transmitted by using the 3.75 kHz subcarrier bandwidth can transmit the signal in other manners in the three consecutive subframes. Resource utilization.

Optionally, the subcarrier bandwidth supported by the wireless communication system may further include a second subcarrier bandwidth, and the network device may determine uplink time domain resources of the plurality of consecutive uplink time domain resources except the first target time domain unit. The second subcarrier bandwidth can be used to carry the uplink signal, thereby maximizing uplink resource utilization and avoiding collisions between uplink signals transmitted using different subcarrier bandwidths.

Optionally, the second subcarrier bandwidth may be 15 kHz.

For example, in the case where a plurality of consecutive uplink time domain resources are 3 consecutive subframes, one subframe other than the first target time domain unit may be used to transmit the uplink signal using the 15 kHz subcarrier bandwidth.

502. The network device sends the first indication information. Correspondingly, the terminal device receives the first indication information.

Optionally, the network device may send a system message, where the system message includes the first indication information.

Specifically, the network device can send a system message to all terminal devices within the coverage. Correspondingly, each terminal device within the coverage of the network device receives the system message. In this way, the network device uniformly sends system messages to the terminal devices in the coverage area, thereby reducing signaling overhead.

Optionally, the network device may receive an uplink signal sent by the terminal device using the first subcarrier bandwidth on all first target time domain units in the wireless communication system.

Optionally, the network device may also send control information, where the control information includes the first indication information.

Specifically, the network device may send control information to the first terminal device of the plurality of terminal devices in the coverage, where the control information includes the first indication information. The first terminal device may be any one of a plurality of terminal devices within the coverage of the network device. Correspondingly, the first terminal device receives the control information. In this way, the network device can send suitable first indication information for different terminal devices, thereby improving the flexibility of uplink signal transmission.

It should be understood that the network device can independently transmit control information for each of a plurality of terminal devices within the coverage.

Optionally, the network device may further send the second indication information to the terminal device, where the second indication information is used by the terminal device to determine whether the first subcarrier bandwidth can be used to carry the uplink on the multiple consecutive uplink time domain resources. signal.

Optionally, the network device determines that the first subcarrier bandwidth cannot be used to carry the uplink signal on the first target time domain unit, and/or the network device determines that the second uplink resource can be used on the multiple consecutive uplink time domain resources. When the subcarrier bandwidth carries the uplink signal, the network device may notify the terminal device by sending the second indication information, so as to avoid the waste of resources caused by the time domain resource when the uplink signal is not transmitted by using the first subcarrier bandwidth. Increased resource utilization.

Specifically, the second indication information may indicate that the first target time domain unit is not capable of using the first subcarrier bandwidth to carry an uplink signal, and/or the second indication information indicates the multiple consecutive uplink time domain resources. The second subcarrier bandwidth can be used to carry the uplink signal.

Optionally, if the network device determines that the terminal device can use the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit, and/or determine that the terminal device cannot be on the first target time domain unit Use the second child The carrier device can transmit the uplink signal, and the network device can also send the second indication information to notify the first terminal device. At this time, the second indication information indicates that the terminal device can use the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit, and/or the second indication information is used to indicate that the terminal device is in the The second subcarrier bandwidth cannot be used to carry the uplink signal on the first target time domain unit.

Optionally, if the network device determines that the terminal device can use the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit, the network device may not send the second indication information, that is, the terminal device may be in the system message by default. The first target time domain unit indicated by the first indication information included transmits the uplink signal using the first subcarrier bandwidth.

Correspondingly, the terminal device receives the second indication information.

Optionally, the sending, by the network device, the second indication information may be by sending control information, where the control information includes the second indication information.

It should be understood that the control information including the second indication information and the control information including the first indication information may be the same control information, which is not limited in this application.

Optionally, the network device may also send a system message, where the system message carries the second indication information.

It should be understood that the system message including the first indication information and the system message including the second indication information may be the same system message, which is not limited in this application.

Optionally, the control information may further include scheduling information, where the scheduling information is used to indicate a time-frequency resource location that is scheduled to be transmitted by the terminal device to the uplink signal.

Optionally, the scheduling information may be used to determine a time domain start time and a transmission duration for transmitting the uplink signal, and a frequency domain resource location.

Optionally, the scheduling information may include downlink control information (DCI) subframe repetition times, scheduling delay, resource allocation, and number of repetitions. The number of times of the DCI subframe repetition, the scheduling delay may be used by the terminal device to determine the time domain start time position of the uplink signal, and the resource allocation and the number of repetitions may be used by the terminal device to determine the transmission duration.

Specifically, the network device starts at a time domain start time of transmitting the uplink signal, and receives the terminal device in the first target time domain unit of all the plurality of consecutive time domain resources after the time domain start time The uplink signal transmitted by the subcarrier bandwidth until all uplink signals are received. That is to say, the sum of the durations corresponding to all the first target time domain units is equal to the transmission duration determined according to the scheduling information.

It should be noted that, according to the number of repetitions of the DCI subframe, the time domain resource corresponding to the time domain location determined by the scheduling delay is an invalid uplink time domain resource, for example, a downlink time domain resource, and the first time after the invalid uplink time domain resource is used. The time domain location corresponding to an uplink time domain resource is the time domain start time position of the uplink signal.

Correspondingly, the terminal device can determine the time domain start time position of the uplink signal according to the scheduling delay, and determine the transmission duration of the uplink signal according to the resource allocation and the number of repetitions. In this way, the terminal device can transmit the uplink signal from the first target time domain unit of the plurality of consecutive time domain resources starting from the start time of the time domain until the transmission of all the uplink signals is completed.

For example, the terminal device determines that the transmission duration is 32 ms. If the first target time domain unit included in each radio frame is 2 ms, 16 first target time domain units are required to complete the transmission of the uplink signal. That is, the first target time domain unit of the plurality of consecutive uplink time domain resources starting from the start time determined by the scheduling information starts to use the first subcarrier bandwidth to transmit the uplink signal, and continues to the next first target time domain unit. The uplink signal is transmitted using the first subcarrier bandwidth until the uplink signal transmission of the transmission duration is completed.

Optionally, the network device sends the first indication information, where the first indication information may include at least one bit, The value of the at least one bit is used to indicate a first target time domain unit of the at least two time domain units. Correspondingly, the terminal device can determine the first target time domain unit of the at least two time domain units according to the value of the at least one bit.

For example, if the time domain configuration supported by the wireless communication system includes three consecutive uplink subframes, there may be two time domain units, the first time domain unit includes the first two consecutive subframes, and the second time domain unit includes the latter. Two consecutive subframes, in the case that the first indication information includes 1 bit, the bit taking 1 may indicate that the first time domain unit is determined as the first target time domain unit, and the bit is 0, indicating that The second time domain unit is determined to be the first target time domain unit.

Optionally, the wireless communication system may include multiple wireless carriers, and the network device may uniformly determine the first indication information for the multiple wireless carriers. The terminal device may determine, according to the first indication information, a first target time domain unit corresponding to the multiple wireless carriers. That is to say, the first target time domain units corresponding to the plurality of wireless carriers are the same.

Optionally, the wireless communication system includes multiple wireless carriers, and the network device may also determine first indication information for each of the plurality of wireless carriers. Correspondingly, the terminal device may determine, according to the first indication information, a first target time domain unit corresponding to each of the plurality of wireless carriers.

Optionally, the network device sends the configuration information of each wireless carrier to the terminal device, where the configuration information of the wireless carrier may carry the corresponding first indication information, thereby improving the flexibility of the uplink signal transmission.

Optionally, the wireless communication system includes a plurality of wireless carriers, the first indication information may include a plurality of bits, and each of the plurality of wireless carriers corresponds to at least one of the plurality of bits, where The first indication information is a value of at least one bit corresponding to one of the plurality of wireless carriers, so that the terminal device can determine the first target corresponding to the corresponding one of the wireless carriers according to the value of the at least one bit. a time domain unit, and transmitting the uplink signal by using the first subcarrier bandwidth on the first target time domain unit. Correspondingly, the network device receives the uplink signal sent by the terminal device in the first subcarrier bandwidth on a first target time domain unit of a wireless carrier.

In this way, the terminal device can determine the corresponding first target time domain unit according to the value of the bit corresponding to each wireless carrier, thereby improving the flexibility of uplink signal transmission and saving signaling overhead.

For example, in a case where the time domain configuration supported by the wireless communication system includes three consecutive uplink time domain resources, the first target time domain unit indicating each wireless carrier may use only one bit, such that the first indication information includes The number of bits may be the same as the number of wireless carriers included in the wireless communication system, that is, the wireless carrier has a one-to-one correspondence with the bits. The network device can indicate the occupancy of the corresponding wireless carrier in three consecutive uplink time domain resources by using the value of each bit.

Optionally, when the wireless communication system is NB-IoT, the wireless carrier is an NB-IoT carrier, and the NB-IoT carrier bandwidth is 180 kHz.

Optionally, the plurality of bits included in the first indication information may be represented by one bitmap.

Optionally, the first indication information and the second indication information may be represented by the same bit. That is, different values of the bits may be used to represent the first indication information and the second indication information, respectively.

For example, for a wireless communication system in which the time domain configuration includes only three consecutive uplink time domain resources, that is, the first indication information indicates that the previous two consecutive uplink time domain resources are the first target time domain unit, or two consecutive consecutive The uplink time domain resource is the first target time domain unit. In this case, the first indication information and the second indication information may be represented by 2 bits, the value of the 2 bits being "0" and the value being "1" may respectively represent the previous 2 consecutive The uplink time domain resource and the following two consecutive uplink time domain resources are the first target time domain unit, and the value of the two bits is “3” and the value of “4” can represent the first target respectively. The first subcarrier bandwidth is used to carry the uplink signal on the domain unit, And the first subcarrier bandwidth is not used to carry the uplink signal on the first target time domain unit.

Optionally, if the network device determines that the first target time domain unit cannot use the first subcarrier bandwidth to carry the uplink signal, or determines that the network device multiple consecutive uplink time domain resources can be used to enable the second subcarrier. The bandwidth carries the uplink signal, and the network device may not send the first indication information. That is to say, the terminal device can use the second subcarrier bandwidth to carry the uplink signal by default, thereby saving the power consumption of the network device.

503. The terminal device, according to the first indication information, uses the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit when transmitting the uplink signal.
