Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a future fifth Generation (5G) System, or a New Radio Network (NR), etc.

Terminal equipment in the embodiments of the present application may refer to user equipment, access terminals, subscriber units, subscriber stations, mobile stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.

The Network device in this embodiment may be a device for communicating with a terminal device, where the Network device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, may also be a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, may also be an evolved node b (eNB, or eNodeB) in an LTE System, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or may be a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network device in a future 5G Network, or a Network device in a future evolved PLMN Network, and the like, and the embodiment of the present invention is not limited.

The communication system of the embodiment of the application can comprise at least one terminal device and a network device. For example, fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. The communication system in fig. 1 may comprise 6 terminal devices (i.e. terminal device 10-terminal device 60) and a network device 70. The network device 70 is used to provide communication services for each terminal device and access the core network. The terminal devices 10 to 60 may respectively perform uplink/downlink transmission with the network device 70 through communication links, where the communication links sent by the network device 70 and received by the terminal devices 10 to 60 are downlink transmission, and the communication links sent by the terminal devices 10 to 60 and received by the network device 70 are uplink transmission.

Furthermore, the terminal devices 40-60 may also constitute a communication system in which the terminal device 50 may transmit information to at least one of the terminal device 40 and the terminal device 60.

The internet of things is a network which acquires information of a physical world by deploying various devices with certain sensing, calculating, executing and passing capabilities, and realizes information transmission, cooperation and processing through a network, so that interconnection of people and objects and interconnection of objects and objects are realized. That is to say, the internet of things is to realize interconnection and intercommunication between people and objects. The Internet of things can be applied to various aspects such as intelligent networks, intelligent agriculture, intelligent transportation, environment monitoring and the like.

The mobile communication standardization organization third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) proposed Narrowband Internet of Things (NB-IoT). The bandwidth of NB-IoT is 180kHz, and the method supports three deployment modes of independent mode (Stand-alone operation), Guard band mode (Guard band operation) and In-band mode (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 transmissions and one or more other carriers are used for LTE transmissions. The guard band pattern is to NB-IoT transmissions using one or more resource blocks not utilized in the LTE carrier guard band. For example, as shown in fig. 3, a guard band of at least one of two end edges in an LTE channel bandwidth may be used for NB-IoT transmission, where the LTE channel bandwidth includes a plurality of resource blocks, and a bandwidth of each resource block is 180 kHz. The in-band mode is to utilize one or more resource blocks within the LTE channel bandwidth for NB-IoT transmissions. For example, as shown in fig. 4, one resource block in the LTE channel bandwidth is used for NB-IoT transmission, wherein the LTE channel bandwidth includes each resource block with a bandwidth of 180 kHz.

Currently, Frequency Division Duplex (FDD) NB-IoT uplinks support two subcarrier bandwidths of 3.75kHz and 15 kHz. Wherein, for 3.75kHz subcarrier bandwidth, the time slot is 2 ms; for a 15kHz subcarrier bandwidth, the time slot is 0.5 ms.

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

TABLE 1

As can be seen from table 1, the number of consecutive uplink subframes in 7 uplink and downlink subframe configurations of TDD LTE is 1, 2, or 3.

In the case that the TDD NB-IoT supports a 3.75kHz subcarrier bandwidth and the timeslot is 2ms for the 3.75 subcarrier bandwidth, the TDD NB-IoT may be compatible with 2 or 3 consecutive uplink and downlink subframes in number. In particular, the TDD NB-IoT may transmit uplink signals using 3.75kHz subcarrier bandwidth with 2 consecutive uplink subframes.

Under the condition that the number of continuous uplink subframes in the uplink and downlink subframe configuration is greater than 2, that is, under the condition that the number of continuous uplink subframes configured by the TDD NB-IoT in the time domain configuration is greater than 2, if the network device only schedules the terminal device to use the 3.75kHz subcarrier bandwidth for uplink transmission, the utilization rate of the TDD NB-IoT uplink resource is reduced.

Fig. 5 shows a schematic flow chart of a method of signal processing of an embodiment of the present application.

The embodiment of the application is applied to a wireless communication system, and the time domain configuration in the wireless communication system may include a plurality of continuous uplink time domain resources.

Optionally, the wireless communication system may be an 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 comprises 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 above-described uplink and downlink subframe configuration of the TDD LTE, or may be other uplink and downlink subframe configurations, and the application is not limited thereto.

Optionally, in this embodiment of the present application, the uplink time domain resource may be an uplink subframe, or may be other time domain resource units. For example, the uplink time domain resource may be an uplink radio frame, an uplink timeslot, an uplink symbol, or the like, and for convenience of description, the embodiment of the present application is described by taking an uplink subframe as an example without specific description, but the present application does not limit this.

Optionally, in this embodiment of the present application, an example that the first subcarrier bandwidth supported by the wireless communication system is 3.75kHz is described.

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

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

Specifically, the number of time domain units may be determined by the number of consecutive uplink time domain resources included in the time domain configuration supported by the wireless communication system 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 3 consecutive uplink time domain resources, and the number of consecutive uplink time domain resources included in each time domain unit is 2, so that when the time domain configuration supported by the wireless communication system includes the 3 consecutive uplink time domain resources, there may be 2 time domain units, and the 2 time domain units respectively include the first 2 consecutive uplink time domain resources and the last 2 consecutive uplink time domain resources.

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

For example, in a case that the time domain configuration supported by the wireless communication system includes the 3 consecutive uplink time domain resources, assuming that three consecutive uplink time domain resources are labeled as a, B, and C, there may be 2 time domain units, where the 2 time domain units respectively include the first 2 consecutive uplink time domain resources and the last 2 consecutive uplink time domain resources, for example, two time domain units may be AB and BC, respectively, and the 2 time domain units include one same uplink 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 is AB or the first time domain unit is BC.

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

Specifically, if the first subcarrier bandwidth is 3.75kHz, the timeslot corresponding to the 3.75kHz subcarrier bandwidth is 2ms, and the uplink time domain resource is a subframe of 1ms, the first two subframes constitute a first time domain unit, the second two subframes constitute 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 used as the first target time domain unit, or that the second time domain unit is used as the first target time domain unit. That is to say, the network device may determine the resource location for transmitting the uplink signal, so that the subframes except the subframe for transmitting the uplink signal using the 3.75kHz subcarrier bandwidth in the 3 consecutive subframes may transmit the signal in other manners, and the embodiment of the present application improves the resource utilization rate.

Optionally, the subcarrier bandwidths supported by the wireless communication system may further include a second subcarrier bandwidth, and the network device may determine that uplink time domain resources other than the first target time domain unit in the multiple consecutive uplink time domain resources may use the second subcarrier bandwidth to carry uplink signals, so as to maximize uplink resource utilization and avoid collision between uplink signals transmitted using different subcarrier bandwidths.

Alternatively, the second subcarrier bandwidth may be 15 kHz.

For example, in the case that the plurality of consecutive uplink time domain resources are 3 consecutive subframes, 1 subframe in addition to the first target time domain unit may be used for transmitting an uplink signal using a 15kHz subcarrier bandwidth.

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

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

Specifically, the network device may send a system message to all terminal devices within the coverage area. Accordingly, each terminal device within the coverage of the network device receives the system message. Therefore, the network equipment uniformly sends the system message to the terminal equipment in the coverage range, thereby reducing the signaling overhead.

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

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

Specifically, the network device may transmit control information to a first terminal device of the plurality of terminal devices within the coverage area, the control information including 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. Accordingly, the first terminal device receives the control information. Therefore, the network equipment can send appropriate first indication information to different terminal equipment, and the flexibility of uplink signal transmission is improved.

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

Optionally, the network device may further send second indication information to the terminal device, where the second indication information is used for the terminal device to determine whether the uplink signal can be carried on the plurality of consecutive uplink time domain resources using the first subcarrier bandwidth.

Optionally, the network device may notify the terminal device by sending the second indication information when determining that the first subcarrier bandwidth cannot be used to carry the uplink signal in the first target time domain unit and/or determining that the second subcarrier bandwidth can be used to carry the uplink signal in the multiple consecutive uplink time domain resources, so as to avoid resource waste caused by remaining reservation of the time domain resources when the first subcarrier bandwidth cannot be used to transmit the uplink signal, thereby improving resource utilization.

Specifically, the second indication information may indicate that the first target time domain unit cannot use the first subcarrier bandwidth to carry the uplink signal, and/or the second indication information indicates that the second subcarrier bandwidth can be used to carry the uplink signal on the multiple consecutive uplink time domain resources.

Optionally, if the network device determines that the terminal device can use the first subcarrier bandwidth to carry the uplink signal in the first target time domain unit, and/or determines that the terminal device cannot use the second subcarrier bandwidth to carry the uplink signal in the first target time domain unit, the network device may also send 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 in the first target time domain unit, and/or the second indication information is used to indicate that the terminal device cannot use the second subcarrier bandwidth to carry the uplink signal in 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 in the first target time domain unit, the network device may also not send the second indication information, that is, the terminal device may default to send the uplink signal in the first target time domain unit indicated by the first indication information included in the system message using the first subcarrier bandwidth.

Accordingly, the terminal device receives the second indication information.

Alternatively, the network device may transmit the second indication information by transmitting control information, which 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 scheduled to the terminal device for transmitting the uplink signal.

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

Optionally, the scheduling information may include a number of Downlink Control Information (DCI) subframe repetitions, a scheduling delay, resource allocation, a number of repetitions, and the like. The DCI subframe repetition number and the scheduling delay may be used by the terminal device to determine a time domain start time position for transmitting the uplink signal, and the resource allocation and the repetition number may be used by the terminal device to determine a transmission duration.

Specifically, the network device starts at a time domain starting time for transmitting the uplink signal, and receives the uplink signal sent by the terminal device with the first subcarrier bandwidth in the first target time domain unit in all the multiple continuous time domain resources after the time domain starting time until all the uplink signals are received. That is, the sum of the time durations corresponding to all the first target time domain units is equal to the transmission time duration determined according to the scheduling information.

It should be noted that, if the time domain resource corresponding to the time domain position determined by the scheduling delay is an invalid uplink time domain resource, for example, a downlink time domain resource, according to the DCI subframe repetition number, the time domain position corresponding to the first uplink time domain resource after the invalid uplink time domain resource is used as the time domain starting time position of the uplink signal.

Accordingly, the terminal device may determine the time domain starting 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 repetition number. In this way, the terminal device may transmit the uplink signal from the first target time domain unit in the multiple continuous time domain resources from the time domain starting time until the transmission of all uplink signals is completed.

For example, the terminal device determines that the transmission duration is 32ms, and if the first target time domain unit included in each radio frame is 2ms, 16 first target time domain units are needed to complete transmission of the uplink signal. That is, a first target time domain unit in a plurality of continuous uplink time domain resources from a starting time determined by the scheduling information starts to transmit the uplink signal by using the first subcarrier bandwidth, and when a next first target time domain unit arrives, the uplink signal is continuously transmitted by using the first subcarrier bandwidth until the transmission of the uplink signal with 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, and a 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. Accordingly, the terminal device may determine a 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 3 consecutive uplink subframes, there may be 2 time domain units, where the first time domain unit includes the first two consecutive subframes, and the second time domain unit includes the second two consecutive subframes, and if 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 taking 0 indicates that the second time domain unit is determined as the first target time domain unit.

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

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

Optionally, the network device sends configuration information of each wireless carrier to the terminal device, and the configuration information of the wireless carrier may carry corresponding first indication information, so as to improve flexibility of uplink signal transmission.

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

Therefore, the terminal equipment 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 that the time domain configuration supported by the wireless communication system includes 3 consecutive uplink time domain resources, the first target time domain unit indicating each wireless carrier may use only one bit, so that the number of bits included in the first indication information may be the same as the number of wireless carriers included in the wireless communication system, i.e., the wireless carriers correspond to the bits one to one. The network device can respectively indicate the occupation situation of the corresponding wireless carrier in 3 continuous uplink time domain resources through the value of each bit.

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

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

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

For example, for a wireless communication system whose time domain configuration includes only 3 consecutive uplink time domain resources, that is, the first indication information indicates that the first 2 consecutive uplink time domain resources are the first target time domain unit, or the second 2 consecutive uplink time domain resources are the first target time domain unit. In this case, the first indication information and the second indication information may be represented by 2 bits, where a value of "0" and a value of "1" of the 2 bits may respectively represent that the first 2 consecutive uplink time domain resources and the second 2 consecutive uplink time domain resources are the first target time domain unit, and a value of "3" and a value of "4" of the 2 bits may respectively represent that the first subcarrier bandwidth is used by the first target time domain unit to carry the uplink signal, and the first subcarrier bandwidth is not used by the first target time domain unit to carry the uplink signal.

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 a plurality of consecutive uplink time domain resources of the network device can be used to use the second subcarrier bandwidth to carry the uplink signal, the network device may not send the first indication information. That is, the terminal device may default that the plurality of consecutive uplink time domain resources may use the second subcarrier bandwidth to carry the uplink signal, thereby saving power consumption of the network device.

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

The network device determines first indication information for indicating that a first target time domain unit in the at least two time domain units can use a first subcarrier bandwidth to carry an uplink signal, and sends the first indication information to the terminal device, and the terminal device receives the first indication information, and the terminal device can use the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit when sending the uplink signal according to the first indication information, thereby being beneficial to improving the utilization rate of uplink resources.

It should be noted that the terminal device may be the first terminal device described above.

Optionally, the uplink time domain resources on the multiple consecutive uplink time domain resources except for the first target time domain unit may further include a second target time domain unit, and the terminal device may determine, according to the first indication information, that the uplink signal can be sent on the second target time domain unit using the second subcarrier bandwidth.

For example, for a wireless communication system whose time domain configuration includes only 3 consecutive uplink time domain resources, if the first two of the 3 consecutive uplink time domain resources are taken as the first target time domain unit, the last uplink time domain resource may be taken as the second target time domain unit; if the last two of the 3 consecutive uplink time domain resources are taken as the first target time domain unit, the first uplink time domain resource may be taken as the second target time domain unit.

Alternatively, the terminal device may transmit the uplink signal using the first subcarrier bandwidth on all the first target time domain units in the wireless communication system.

Optionally, the terminal device may send the uplink signal by using the first subcarrier bandwidth in a first target time domain unit corresponding to a time-frequency resource position scheduled by the network device to the terminal device.

Optionally, the subcarrier bandwidth supported by the wireless communication system network further includes a second subcarrier bandwidth, and if the second indication information indicates that the uplink signal can be carried on the multiple consecutive uplink time domain resources using the first subcarrier bandwidth, and/or the second indication information indicates that the uplink signal cannot be carried on the multiple consecutive uplink time domain resources using the second subcarrier bandwidth, the terminal device may send the uplink signal on the first target time domain unit corresponding to the time-frequency resource position scheduled by the network device to the terminal device using the first subcarrier bandwidth.

Optionally, the terminal device may also transmit the uplink signal on the second target time domain unit using the second subcarrier bandwidth.

Optionally, the subcarrier bandwidth supported by the wireless communication system network further includes a second subcarrier bandwidth, and the second indication information indicates that the first target time domain unit in the at least two time domain units cannot use the first subcarrier bandwidth to carry the uplink signal, and/or the second indication information indicates that the second subcarrier bandwidth can be used to carry the uplink signal on the multiple consecutive uplink time domain resources, so that the terminal device may use the second subcarrier bandwidth to send the uplink signal on the multiple consecutive uplink time domain resources corresponding to the time-frequency resource position scheduled by the network device to the terminal device.

Therefore, in the signal processing method according to the embodiment of the present application, the network device determines first indication information for indicating that the first target time domain unit of the at least two time domain units can use the first subcarrier bandwidth to carry the uplink signal, and sends the first indication information to the terminal device, and the terminal device can use the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit when sending the uplink signal according to the first indication information, thereby facilitating improvement of utilization rate of uplink resources.

Fig. 6 shows a method of signal processing according to another embodiment of the present application.

601, the network device determines first indication information, where the first indication information is used to indicate a first target uplink time domain resource in the 3 consecutive uplink time domain resources, and the first target uplink time domain resource is a first uplink time domain resource or a last uplink time domain resource in the 3 consecutive uplink time domain resources.

The first target uplink time domain resource in this embodiment may be a second target time domain unit in the embodiment shown in fig. 5. To avoid repetition, the same scheme as the second target time domain unit is not described herein again.

The network device sends 602 the first indication information.

Specifically, the manner in which the network device transmits the first indication information may be the same as the manner in which the first indication information is transmitted in the embodiment shown in fig. 5.

603, according to the first indication information, when sending an uplink signal, the terminal device uses the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit.

The way that the terminal device uses the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit when sending the uplink signal according to the first indication information may be the same as the way that the terminal device uses the first subcarrier bandwidth to carry the uplink signal on the first target time domain unit when sending the uplink signal in the embodiment shown in fig. 5.

Optionally, the terminal device may be configured to send the uplink signal using the first subcarrier bandwidth in the first target uplink time domain resource.

Alternatively, the first subcarrier bandwidth may be 15 kHz.

Optionally, the first indication information may also indicate that, of the 3 consecutive uplink time domain resources, the uplink time domain resource other than the first target uplink time domain resource is an uplink time domain resource capable of using a second carrier bandwidth to carry an uplink signal.

Optionally, the second subcarrier bandwidth may be 3.75 kHz.

Optionally, the subcarrier bandwidths supported by the system include a first subcarrier bandwidth and a second subcarrier bandwidth, and the method further includes: the network device determines that the first subcarrier bandwidth cannot be used to carry uplink signals on the first target uplink time domain resource and/or determines that the second subcarrier bandwidth can be used to carry the uplink signals on the 3 consecutive uplink time domain resources; the network device does not send the first indication information.

604, when the terminal device sends the uplink signal, the terminal device uses the first subcarrier bandwidth to carry the uplink signal on the uplink time domain resource except the first target uplink time domain resource among the 3 consecutive uplink time domain resources.

Optionally, in this embodiment of the present application, after determining a first target uplink time domain resource in 3 consecutive uplink time domain resources, the terminal device may further determine the remaining two consecutive uplink time domain resources in the 3 consecutive uplink time domain resources as a second target uplink time domain resource. The terminal device may use the second subcarrier bandwidth to carry the uplink signal in the second target uplink time domain resource, thereby facilitating to improve the utilization rate of the uplink resource. In addition, the network device does not need to send independent indication information to indicate that the remaining two continuous uplink time domain resources are determined as the second target uplink time domain resource, so that the power consumption of the system is saved.

Optionally, after the network device sends the first indication information, the network device also sends second indication information, where the second indication information is used to indicate whether the uplink signal is carried on the 3 consecutive uplink time domain resources using the first subcarrier bandwidth.

It should be understood that the sending mode of the second indication information may also be the same as the sending mode of the second indication information in the embodiment shown in fig. 5, and the present application does not limit this.

Optionally, the terminal device may use the uplink signal sent by the first subcarrier bandwidth on the first target uplink time domain resource corresponding to the time frequency resource position scheduled by the network device to the terminal device. Accordingly, the network device may also receive the upstream signal.

Optionally, the uplink time domain resources, except for the first target uplink time domain resource, of the 3 consecutive uplink time domain resources include a second target uplink time domain resource, and the terminal device may also receive the uplink signal sent by the terminal device using the second subcarrier bandwidth on the second target uplink time domain resource corresponding to the time frequency resource position scheduled to the terminal device by the network device. Accordingly, the network device may also receive the upstream signal.

Optionally, the terminal device may also receive the uplink signal sent by the terminal device using the second subcarrier bandwidth on the multiple continuous uplink used resources corresponding to the time-frequency resource position scheduled by the network device to the terminal device. Accordingly, the network device may also receive the upstream signal.

Optionally, the system includes a plurality of wireless carriers, the first indication information includes a plurality of bits, each of the plurality of wireless carriers corresponds to at least one of the plurality of bits, and a value of at least one bit corresponding to a target wireless carrier of the plurality of wireless carriers is used to indicate the first target uplink time domain resource corresponding to the target wireless carrier. That is, the terminal device may determine the corresponding first uplink time domain resource according to the value of the bit corresponding to each wireless carrier, thereby improving the flexibility of uplink signal transmission.

Therefore, in the method for processing signals in this embodiment of the present application, the network device determines first indication information indicating that a first uplink time domain resource or a last uplink time domain resource in the 3 consecutive uplink time domain resources is a first target uplink time domain resource, and sends the first indication information to the terminal device, and the terminal device uses the first subcarrier bandwidth to carry the uplink signal on the first target uplink time domain resource when sending the uplink signal according to the first indication information, thereby facilitating improvement of the utilization rate of the uplink resource.
