Description

Signal processing method, signal sending method and device TECHNICAL FIELD

[0001] The present application relates to the field of communication technology. BACKGROUND

[0002] From the early era of 2G system to 4G system, the main service object of the cellular mobile communication system is the mobile terminal equipment held by people. With the rapid development of mobile Internet and Internet of Things, since the late era of 4G system, the application scenarios of Internet of Things considered and supported in the evolution process of the cellular mobile communication system are more and more rich, and accordingly more kinds of Internet of Things device terminal types are supported and landed in actual network deployment and service application, for example, enhanced Machine-Type Communication (eMTC) type terminal device, Narrow Band Internet of Things (NB-IoT) type terminal device, RedCap type terminal device, etc. With the strengthening of the diversity of Internet of Things terminal device types, the cellular mobile system has stronger and stronger service ability for vertical industry.

[0003] However, in the massive Internet of Things devices, the field of large number and lower cost Internet of Things terminal devices is still a blank of the cellular mobile communication system. In order to be able to provide more robust, more reliable and more complete Internet of Things application solutions, how to support lower cost Internet of Things terminal devices in the 3GPP cellular mobile system has become a problem to be solved.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical scheme of the present application, and for the convenience of understanding by those skilled in the art. The above technical scheme cannot be considered as known to those skilled in the art only because it is described in the background section of the present application.

[0005] SUMMARY

[0006] Radio Frequency Identification (RFID) system is a solution for the field of Internet of Things (IoT) terminal devices with large quantity and lower cost. RFID system is widely applied. The advantage of RFID system is that the tag cost is low and the price is cheap. The RFID tag size is small, and the size and material of the applied object are less limited, so it is easier to apply to various object management and object tracking scenarios. One disadvantage of the RFID system is that the information reading range of the RFID tag (based on the communication range of the wireless signal) is small. Using the artificial handheld tag reader scheme, the labor cost may become the main expense of the use cost. Using a special RFID port or gateway to read and manage RFID tags requires a higher deployment cost. In addition, the simple logical architecture of the RFID system cannot better coordinate the interference in the radio wave transmission, so the system capacity and spectrum use efficiency are generally low.

[0007] Compared with the RFID system, in the 3GPP 5G system, tag-type terminal devices are supported, which can reuse the existing base station deployment and support industry applications based on this type of terminal through the existing cellular mobile communication network, thereby effectively reducing the deployment cost and use cost. The 3GPP 5G system can provide reliable authentication, network coordination, and accurate and stable terminal device management mechanism, and can also optimize the network based on this to improve the system capacity and spectrum use efficiency.

[0008] Supporting tag-type terminal devices can also be called ambient IoT devices, which can be called AIoT (Ambient internet of thigs, AIoT) devices, ambient IoT devices, passive IoT devices, and can also be simply referred to as tag-type devices, etc. The device that directly communicates with the AIoT device is called a reader, or an interrogator, etc. The reader can exist in the network device, so that the AIoT device and the 5G network can directly communicate, without the terminal device transmitting information between the AIoT device and the 5G network. The reader can also exist in the terminal device, so that the indirect network communication of the ambient IoT is realized, indicating that in the communication between the ambient IoT device and the 5G network, the terminal device supporting the ambient IoT helps to transmit information between the ambient IoT device and the 5G network.

[0009] The inventors find that, as a new type of Internet of Things terminal in the 5G system, the cost of the tag type terminal device (ambient IoT device) is severely limited. The hardware capability of the device is obviously weaker than that of the ordinary smart phone and other existing cellular mobile communication system supported Internet of Things type devices. For example, the signal processing capability of the tag type terminal device is very limited, and the crystal oscillator it carries may have a large error, and its ability to obtain accurate time-frequency synchronization is poor. The existing 5G system mechanism for terminal device to send uplink signal cannot be reused. Therefore, how to solve the sending of the tag type terminal uplink signal becomes a problem to be solved.

[0010] To solve at least one of the above problems, embodiments of the present application provide a signal processing method, a signal sending method, a device and a communication system.

[0011] According to an aspect of the embodiments of the present application, a signal processing device is provided, applied to a terminal device, comprising:

[0013] The processing unit determines the related information of a second time-frequency resource, wherein the second time-frequency resource is used to carry a second signal sent by the terminal device to the first device, and the second signal is related to the first signal.

[0014] According to another aspect of the embodiments of the present application, a signal sending device is provided, applied to a network device, comprising:

[0015] The sending unit sends a first signal to a terminal device on a first time-frequency resource;

[0016] The terminal device determines the related information of a second time-frequency resource, wherein the second time-frequency resource is used to carry a second signal sent by the terminal device to the first device, and the second signal is related to the first signal.

[0018] The terminal device comprises the device of the aforementioned aspect,

[0019] The network device comprises the device of the aforementioned another aspect.

[0020] One of the beneficial effects of the embodiments of the present application is that: by determining the related information of the second time-frequency resource of the second signal related to the first signal, the first device can effectively perform interference coordination and management, and improve the spectrum use efficiency; and by the determined related information of the second time-frequency resource, the terminal device timing error can be coped with, so that the terminal device can make the transmitted second signal be completely received even if a low-cost local oscillator is used, the collision of the second signal transmitted by the terminal device with other uplink signals or downlink signals can be avoided, the accuracy of signal receiving or transmitting is improved, and the uplink coverage of the network is improved.

[0109] For example, the first parameter is used to determine the earliest starting position of the second time-frequency resource, or in other words, the first parameter is used to determine a position in time domain (a position in time domain) and the second time-frequency resource does not start earlier than the position; for another example, the first parameter is used to determine the latest starting position of the second time-frequency resource, or in other words, the first parameter is used to determine a position in time domain and the second time-frequency resource does not start later than the position; for yet another example, the first parameter is used to determine the earliest starting position and the latest starting position of the second time-frequency resource.

[0110] The following examples illustrate how the terminal device determines the starting position of the second time-frequency resource according to at least the first parameter.

[0111] As an example, the terminal device determines the starting position of the second time-frequency resource according to the first parameter. For example, the first parameter indicates the starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the first parameter.

[0112] As another example, the terminal device determines the starting position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the earliest starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the first parameter and in reference to a timing error and / or processing timing, etc. of the terminal device. For example, the timing error is caused by a sampling frequency offset (SFO) of the AIoT device. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the starting time thereof is not earlier than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0113] As another example, the terminal device determines the starting position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the latest starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the first parameter and in reference to a timing error and / or processing timing, etc. of the terminal device. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the starting time thereof is not later than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0114] As another example, the terminal device determines the starting position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the earliest starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the first parameter and in reference to a timing error and / or processing timing, etc. of the terminal device. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the starting time thereof is not earlier than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0115] In some embodiments, the first parameter is used to determine the ending position of the second time-frequency resource.

[0116] For example, the first parameter is used to determine the earliest ending position of the second time-frequency resource, or the first parameter is used to determine a time domain position and the second time-frequency resource ends no earlier than the position; as another example, the first parameter is used to determine the latest ending position of the second time-frequency resource, or the first parameter is used to determine a time domain position and the second time-frequency resource ends no later than the position; as yet another example, the first parameter is used to determine the earliest ending position and the latest ending position of the second time-frequency resource.

[0117] In other embodiments, the first parameter indicates the starting position and the duration of the second time-frequency resource, and the terminal device determines the ending position of the second resource through the first parameter.

[0118] For example, the first parameter indicates a starting position and a minimum duration of the second time-frequency resource, and the terminal device determines an earliest ending position of the second resource according to the indication of the first parameter; for another example, the first parameter indicates a starting position and a maximum duration of the second time-frequency resource, and the terminal device determines a latest ending position of the second resource according to the first parameter; for yet another example, the first parameter indicates a starting position, a minimum duration and a maximum duration of the second time-frequency resource, and the terminal device determines an earliest ending position and a latest ending position of the second resource according to the first parameter.

[0119] The following examples respectively illustrate that the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter;

[0120] As an example, the terminal device determines the ending position of the second time-frequency resource according to the first parameter. For example, the first parameter indicates the ending position of the second time-frequency resource. The terminal device determines the ending position of the second time-frequency resource according to the first parameter.

[0121] As another example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates an earliest ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the first parameter in reference to a timing error and / or processing timing of the terminal device, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the ending time thereof is not earlier than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0122] As yet another example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates a latest ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the first parameter in reference to a timing error and / or processing timing of the terminal device, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the ending time thereof is not later than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0123] As still another example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates an earliest ending position and a latest ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the first parameter in reference to a timing error and / or processing timing of the terminal device, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the ending time thereof is not later than the latest ending time indicated by the first parameter, and is not earlier than the earliest ending time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0124] As a further example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the starting position and the duration of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the first parameter.

[0125] As a further example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the starting position and the minimum duration of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the first parameter and in reference to its timing error and / or processing timing, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the ending time thereof is not earlier than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0126] As a further example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the starting position and the maximum duration of the second time-frequency resource. The terminal device determines the ending position of the second time-frequency resource according to the first parameter and in reference to its timing error and / or processing timing, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the ending time thereof is not later than the time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0127] As a further example, the terminal device determines the ending position of the second time-frequency resource according to at least the first parameter. For example, the first parameter indicates the starting position, the minimum and maximum durations of the second time-frequency resource. The terminal device determines the ending position of the second time-frequency resource according to the first parameter and in reference to its timing error and / or processing timing, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, the ending time thereof is not later than the latest ending time indicated by the first parameter, and is not earlier than the earliest ending time indicated by the first parameter, so that the network side can accurately receive the second signal.

[0128] In some embodiments, the first parameter is used to determine the starting position and the ending position of the second time-frequency resource.

[0129] For example, the first parameter contains both the parameter for determining the starting position of the second time-frequency resource and the parameter for determining the ending position of the second time-frequency resource; the terminal device determines the starting position and the ending position of the second time-frequency resource according to the first parameter, for example similar to the foregoing embodiments, which will not be repeated here.

[0130] In some embodiments, the terminal device determines the time domain related information of the second time-frequency resource according to at least the related information of the third time-frequency resource.

[0131] For example, the second time-frequency resource is related to the third time-frequency resource.

[0132] In some embodiments, the terminal device determines the related information of the third time-frequency resource; and the terminal device determines the start position and / or the end position of the second time-frequency resource according to the related information of the third time-frequency resource.

[0133] In some embodiments, the first device reserves and / or schedules additional resources when configuring the third time-frequency resource.

[0134] For example, the first device configures the third time-frequency resource to be larger than the second time-frequency resource actually used by the terminal device to send the second signal when configuring the third time-frequency resource, so as to cope with the timing error of the terminal device.

[0135] In this way, the terminal device can send a complete second signal within the configured third time-frequency resource, and the terminal device can send the second signal according to the scheduling of the first device even if a low-cost local oscillator is used.

[0136] In some embodiments, the terminal device determines the related information of the third time-frequency resource according to the first information carried in the first signal.

[0137] For example, the terminal device determines the related information of the third time-frequency resource according to the first information, and then the terminal device determines the start position and / or the end position of the second time-frequency resource according to the related information of the third time-frequency resource.

[0138] For example, due to the timing error of the terminal device, or the error between the reference time axis used by the terminal device and the reference time axis used by the first device, after the terminal device determines the related information of the third time-frequency resource, the terminal device needs to determine the start position of the second time-frequency resource and / or the end position of the sending.

[0139] In some embodiments, the related information of the third time-frequency resource is used to determine the start position of the second time-frequency resource.

[0140] For example, the terminal device determines the related information of the third time-frequency resource, and the terminal device determines the start position of the second time-frequency resource, wherein the start position of the second time-frequency resource is related to the start position of the third time-frequency resource.

[0141] In some embodiments, the terminal device determines the start position and / or the earliest start position and / or the latest start position of the third time-frequency resource according to the first information, and then determines the start position of the second time-frequency resource.

[0142] The following examples illustrate that the terminal device determines the start position of the second time-frequency resource according to at least the start position and / or the earliest start position and / or the latest start position of the third time-frequency resource.

[0143] As an example, the terminal device determines a starting position of the third time-frequency resource according to the first information, and determines a starting position of the second time-frequency resource according to the determined starting position of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the starting time of the second signal carried by the second time-frequency resource when reaching the network side is not earlier than the starting position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0144] As another example, the terminal device determines an earliest starting position of the third time-frequency resource according to the first information, and determines a starting position of the second time-frequency resource according to the determined earliest starting position of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the starting time of the second signal carried by the second time-frequency resource when reaching the network side is not earlier than the earliest starting position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0145] As yet another example, the terminal device determines a latest starting position of the third time-frequency resource according to the first information, and determines a starting position of the second time-frequency resource according to the determined latest starting position of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the starting time of the second signal carried by the second time-frequency resource when reaching the network side is not later than the latest starting position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0146] As yet another example, the terminal device determines an earliest and a latest starting position of the third time-frequency resource according to the first information, and determines a starting position of the second time-frequency resource according to the determined earliest and latest starting positions of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the starting time of the second signal carried by the second time-frequency resource when reaching the network side is not earlier than the earliest starting position of the third time-frequency resource and not later than the latest starting position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0147] In some embodiments, the related information of the third time-frequency resource is used to determine the ending position of the second time-frequency resource; the terminal device determines the related information of the third time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource, wherein the ending position of the second time-frequency resource is related to the ending position of the third time-frequency resource.

[0148] For example, the terminal device determines the ending position and / or the earliest ending position and / or the latest ending position of the third time-frequency resource according to the first information, and then determines the ending position of the second time-frequency resource.

[0149] For another example, the terminal device further determines the end position and / or the earliest end position and / or the latest end position of the third time-frequency resource according to the start position and the duration / minimum duration / maximum duration of the third time-frequency resource, and then determines the end position of the second time-frequency resource.

[0150] The following examples illustrate how the terminal device determines the end position of the second time-frequency resource according to the end position and / or the earliest end position and / or the latest end position of the third time-frequency resource.

[0151] As an example, the terminal device determines the end position of the third time-frequency resource according to the first information, and then determines the end position of the second time-frequency resource according to the determined end position of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the second signal carried by the second time-frequency resource reaches the network side at a time not earlier than the end position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0152] As another example, the terminal device determines the earliest end position of the third time-frequency resource according to the first information, and then determines the end position of the second time-frequency resource according to the determined earliest end position of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the second signal carried by the second time-frequency resource reaches the network side at a time not earlier than the earliest end position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0153] As yet another example, the terminal device determines the latest end position of the third time-frequency resource according to the first information, and then determines the end position of the second time-frequency resource according to the determined latest end position of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the second signal carried by the second time-frequency resource reaches the network side at a time not later than the latest end position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0154] As yet another example, the terminal device determines the earliest and latest end positions of the third time-frequency resource according to the first information, and then determines the end position of the second time-frequency resource according to the determined earliest and latest end positions of the third time-frequency resource and the timing error of the terminal device. In this way, it can be ensured that the second signal carried by the second time-frequency resource reaches the network side at a time not earlier than the earliest end position of the third time-frequency resource and not later than the latest end position of the third time-frequency resource, so that the network side can accurately receive the second signal.

[0155] In some embodiments, the related information of the third time-frequency resource is used to determine the start position and the end position of the second time-frequency resource. In some embodiments, the related information of the third time-frequency resource is used to determine the start position and the end position of the second time-frequency resource.

[0156] For example, the terminal device determines the third time-frequency resource, and the terminal device determines the start position and the end position of the second time-frequency resource, wherein the start position and the end position of the second time-frequency resource are related to the third time-frequency resource.

[0157] For example, the terminal device determines the start position and / or the earliest start position and / or the latest start position and / or the end position and / or the earliest end position and / or the latest end position of the third time-frequency resource according to the first information, and then determines the start position and the end position of the second time-frequency resource. The determination method of the start position and the end position of the second time-frequency resource is similar to the foregoing embodiments, which will not be enumerated one by one here.

[0158] In some embodiments, the third time-frequency resource contains the second time-frequency resource, and / or the second time-frequency resource coincides with or is the same as the third time-frequency resource.

[0159] For example, the terminal device expects that the duration of the third time-frequency resource obtained through the first information is not less than the duration of the second time-frequency resource, or the terminal device expects that the third time-frequency resource configured by the first device contains the second time-frequency resource.

[0160] For example, the terminal device does not send the second signal on the time domain resource outside the third time-frequency resource.

[0161] FIG. 3 is a schematic diagram of the second time-frequency resource and the third time-frequency resource according to an embodiment of the present application; and FIG. 4 is another schematic diagram of the second time-frequency resource and the third time-frequency resource according to an embodiment of the present application.

[0162] As shown in FIG. 3, the start position of the third time-frequency resource configured by the first device (for example, indicated by the first information) is earlier than the start position of the second time-frequency resource actually used by the terminal device to send the second signal, and the end position of the third time-frequency resource configured by the first device (for example, indicated by the first information) is not earlier than the end position of the second time-frequency resource actually used by the terminal device to send the second signal.

[0163] As shown in FIG. 4, the start position of the third time-frequency resource configured by the first device (for example, indicated by the first information) is earlier than the start position of the second time-frequency resource actually used by the terminal device to send the second signal, and the duration of the third time-frequency resource configured by the first device is not less than the duration of the second time-frequency resource actually used by the terminal device to send the second signal.

[0164] Therefore, the terminal device can send the complete second signal within the configured third time-frequency resource, and the terminal device can send the second signal according to the scheduling of the first device even if a low-cost local oscillator is used.

[0165] In some embodiments, the first device does not reserve and / or schedule additional resources when configuring the third time-frequency resource.

[0166] For example, the second signal containing timing error transmitted by the terminal device is dealt with by the implementation algorithm of the first device without considering the timing error of the terminal device.

[0167] In this way, the timing error of the terminal device is dealt with by the implementation of the first device, and the terminal device does not perform additional processing on the timing error when transmitting the second signal according to the scheduling of the first device, which can further reduce the complexity of the terminal device.

[0168] In some embodiments, the terminal device determines the third time-frequency resource, and the terminal device determines the start position of the second time-frequency resource, which is related to the start position of the third time-frequency resource.

[0169] In some embodiments, the related information of the third time-frequency resource is used to determine the start position of the second time-frequency resource; and the terminal device determines the start position of the second time-frequency resource according to the third time-frequency resource.

[0170] As an example, the terminal device determines the start position of the second time-frequency resource according to the start position of the third time-frequency resource determined according to the first information, wherein the start position of the second time-frequency resource determined by the terminal device is the same as the start position of the third time-frequency resource.

[0171] In some embodiments, the related information of the third time-frequency resource is used to determine the end position of the second time-frequency resource; and the terminal device determines the end position of the second time-frequency resource according to the third time-frequency resource.

[0172] As an example, the terminal device determines the end position of the second time-frequency resource according to the end position of the third time-frequency resource determined according to the first information, wherein the end position of the second time-frequency resource determined by the terminal device is the same as the end position of the third time-frequency resource.

[0173] In some embodiments, the related information of the third time-frequency resource is used to determine the start position and the end position of the second time-frequency resource; and the terminal device determines the start position and the end position of the second time-frequency resource according to the third time-frequency resource.

[0174] As an example, the terminal device determines the start position and the end position of the second time-frequency resource according to the start position and the end position of the third time-frequency resource determined according to the first information, wherein the start position and the end position of the second time-frequency resource determined by the terminal device are the same as the start position and the end position of the third time-frequency resource.

[0175] In some embodiments, the second signal transmitted by the terminal device has a timing error, and the first device implements an algorithm to cope with the timing error.

[0176] For example, the first device can receive the second signal in a time window larger than the third time-frequency resource; for another example, the first device can track and reproduce the timing error of the terminal device through the second sub-signal, and then receive the second signal.

[0177] In some embodiments, the terminal device determines the time domain related information of the second time-frequency resource according to at least the first parameter and the related information of the third time-frequency resource.

[0178] For example, the terminal device determines the related information of the second time-frequency resource, such as the starting position and / or the ending position of the second time-frequency resource, according to at least the first parameter and the determined third time-frequency resource.

[0179] In some embodiments, the terminal device determines the starting position of the second time-frequency resource according to the first parameter, and then determines the related information of the third time-frequency resource, and then determines the ending position of the second time-frequency resource.

[0180] In some embodiments, the terminal device determines the related information of the third time-frequency resource, and then determines the starting position of the second time-frequency resource, and then determines the ending position of the second time-frequency resource according to the first parameter.

[0181] In some embodiments, the terminal device determines the starting position of the second time-frequency resource according to the first parameter or the third time-frequency resource.

[0182] In some embodiments, the terminal device further indicates the ending position of the second time-frequency resource through the second sub-signal, such as the post-amble of the second signal.

[0183] For how the terminal device determines the related information of the third time-frequency resource:

[0184] For example, as in the foregoing embodiments, the first device transmits first information to the terminal device, and the first information is carried in the first signal, and the first information is used by the terminal device to determine the third time-frequency resource, wherein the third time-frequency resource is available for the transmission of the second signal and / or is preserved for the transmission of the second signal.

[0185] For example, as in the foregoing embodiments, the terminal device transmits the second signal on at least part of the third time-frequency resource.

[0186] Therefore, the terminal device transmits the second signal according to the scheduling of the first device, and the first device can schedule resources, coordinate and manage interference, thereby improving the spectrum utilization of the system.

[0187] In some embodiments, the terminal device determines the related information of the third time-frequency resource according to at least one of the following: the first time reference point and / or the first time offset; the second time reference point and / or the second time offset; the first time duration related information.

[0188] In some embodiments, the first time reference point and / or the second time reference point is at least one of the following: a starting position, an ending position, or an intermediate position of the first information and / or the first sub-signal and / or the second sub-signal and / or the third time-frequency resource.

[0189] The specific content of the first time reference point and / or the first time offset; the second time reference point and / or the second time offset; the first time duration related information is described as follows.

[0190] In some embodiments, the first time reference point and / or the first time offset is used to determine a starting position and / or an earliest starting position and / or a latest starting position of the third time-frequency resource.

[0191] For example, the terminal device determines the starting position and / or the earliest starting position and / or the latest starting position of the third time-frequency resource through the first time reference point and / or the first time offset, wherein the first time reference point is a reference point or a starting point of the first time offset; for example, the first time offset is a time interval from the first time reference point to the starting position of the third time-frequency resource; for example, the first time offset can correspond to the starting position of the third time-frequency resource, can correspond to the earliest starting position of the third time-frequency resource, or can correspond to the latest starting position of the third time-frequency resource.

[0192] In some embodiments, the first time reference point is any one of the following: a starting position, an ending position, or an intermediate position of the time domain resource (first time domain resource) where the first information is located.

[0193] For example, the first time reference point is the starting position of the time domain resource (first time domain resource) where the first information is located, so that the terminal device can confirm the reference point position faster and speed up the processing process.

[0194] For another example, the first time reference point is the ending position of the time domain resource (first time domain resource) where the first information is located, so that the memory size of the signal processing process of the terminal device can be reduced.

[0195] For another example, the first time reference point is any one of the following: a starting position, an ending position, or an intermediate position of the adjacent (previous) or previous several third time-frequency resources.

[0196] In some embodiments, the second time reference point and / or the second time offset are used to determine the ending position and / or the earliest ending position and / or the latest ending position of the third time-frequency resource.

[0197] For example, the terminal device determines the ending position and / or the earliest ending position and / or the latest ending position of the third time-frequency resource according to the second time reference point and / or the second time offset, wherein the second time reference point is a reference point or a starting point of the second time offset; and the second time offset is a time interval from the second time reference point to the ending position of the third time-frequency resource.

[0198] In some embodiments, the second time offset can correspond to the ending position of the third time-frequency resource, or can correspond to the earliest ending position of the third time-frequency resource, or can correspond to the latest ending position of the third time-frequency resource.

[0199] In some embodiments, the second time reference point is any position in the time domain resource (the first time-frequency resource) where the first information is located, such as a starting position, an ending position or an intermediate position.

[0200] For example, the second time reference point is the starting position of the time domain resource (the first time-frequency resource) where the first information is located. In this way, the terminal device can confirm the reference point position faster and speed up the processing process.

[0201] For another example, the second time reference point is the ending position of the time domain resource (the first time-frequency resource) where the first information is located. In this way, the memory size of the signal processing process of the terminal device can be reduced.

[0202] For another example, the second time reference point is any position in the starting position or the ending position or the intermediate position of the adjacent (previous) or previous several third time-frequency resources.

[0203] In some embodiments, the terminal device determines the third time-frequency resource according to the starting position and / or the earliest starting position and / or the latest starting position of the third time-frequency resource determined according to the first time reference point and the first time offset, and / or the ending position and / or the earliest ending position and / or the latest ending position of the third time-frequency resource determined according to the second time reference point and the second time offset.

[0204] In some embodiments, the first time reference point and / or the second time reference point can also be the starting position or the ending position of the time domain resource where the first sub-signal is located. In this way, even if there is no downlink information sent to the terminal device, the terminal device can further correct its local clock by receiving the first signal.

[0205] In some embodiments, the first time reference point and / or the second time reference point can also be a starting position or an ending position of the time domain resource where the second sub-signal is located.

[0206] In some embodiments, the first time reference point and the second time reference point are the same or different, and the first time reference point and / or the second time reference point is determined by the first information and / or in a predefined manner.

[0207] For example, the first time reference point and the second time reference point for determining the related information of the third time-frequency resource can be the same, and the terminal device determines the starting position and the ending position of the third time-frequency resource based on the same time reference point; for another example, the first time reference point and the second time reference point for determining the related information of the third time-frequency resource can be different, and the terminal device determines the starting position and the ending position of the third time-frequency resource based on different time reference points, respectively.

[0208] For another example, the first time reference point corresponding to the starting position of the third time-frequency resource is the ending position of the first sub-signal preamble, and the second time reference point corresponding to the ending position of the third time-frequency resource is the ending position of the first sub-signal postamble.

[0209] In some embodiments, the first time reference point and / or the second time reference point can also be determined in a predefined manner.

[0210] For example, the terminal device defaults the first time reference point to be the starting position of the time domain resource (the first time-frequency resource) where the first information is located, and the second time reference point to be the ending position of the time domain resource (the first time-frequency resource) where the first information is located. In this way, the size of the data carried by the first information can be reduced, and thus the size of the memory of the terminal device can be reduced.

[0211] In some embodiments, the first time offset and / or the second time offset and / or the first duration-related information is determined by at least one or more time units.

[0212] For example, the first time offset and / or the second time offset and / or the first duration-related information is determined by one or more time units.

[0213] For example, the time unit is at least one of the following: sampling time, chip duration, coded word duration, modulation symbol duration, time slot, sub-frame, frame; or absolute time unit, such as: microsecond, millisecond, second, etc.

[0214] For example, the time unit can be determined in a predefined manner, so that the first device and the terminal device have a consistent understanding of it.

[0215] In some embodiments, the time units corresponding to the first time offset, the second time offset, and the first duration can be the same, and the terminal device measures the first time offset, the second time offset, and the first duration in the same time unit; or the time units corresponding to the first time offset, the second time offset, and the first duration can be different, and the terminal device measures the first time offset, the second time offset, and the first duration in different time units, for example, the time units of the first time offset and the second time offset are sampling time, and the time unit of the first duration is chip duration, and the like, which are not limited in the present application.

[0216] In some embodiments, the first duration related information is used to determine the duration and / or the minimum duration and / or the maximum duration of the third time-frequency resource.

[0217] For example, the first duration related information of the third time-frequency resource is used to indicate the duration of the third time-frequency resource.

[0218] In some embodiments, the first duration can be represented by one or more time units.

[0219] For example, the duration of the third time-frequency resource is K OFDM symbol durations; thus, the terminal device determines the third time-frequency resource through the first time reference point, the first time offset, and the first duration.

[0220] In some embodiments, the first duration related information is determined by the length information indicated by the first device and / or a predefined manner.

[0221] As an example, the first duration related information can be obtained by the length information indicated by the first device.

[0222] For example, the length information indicated by the first device is the length of the second information, which can be at least the length of a data block delivered by the MAC layer to the physical layer, or the length of control information generated by the physical layer.

[0223] For example, the length information indicated by the first device can also be the length of the data block and the control information, or the length of the data obtained after the data block and the control information are processed by part or all of the physical layer signal processing procedures. For example, the physical layer signal processing procedures include but are not limited to CRC addition, encoding, modulation, and the like, for example, the CRC addition, encoding, modulation, and the like can refer to prior art solutions, which are not limited in the present application.

[0224] For example, the length information indicated by the first device is the size of the data obtained after the data block and the control information are added with CRC and encoded; for example, after the terminal device receives the length information, the terminal device determines the first duration of the third time-frequency resource by calculation in combination with the parameters configured by the base station device and / or the predefined parameters, such as the number of bits of CRC, the code rate of encoding, etc., and determines the third time-frequency resource in combination with the first time reference point and the first time offset.

[0225] As another example, the first duration related information can be predefined. For example, for some first signals, the length of the second information (the first duration of the third time-frequency resource) required to be fed back by the terminal device is predefined, and the terminal device determines the first duration according to the predefined information length and other related parameters.

[0226] As yet another example, the first device can not configure the first duration, and the terminal device adds a pre-synchronization code and a post-synchronization code before and after the second information respectively, wherein the time length between the pre-synchronization code and the post-synchronization code is the duration of the second information.

[0227] In some embodiments, the first device can further configure additional length information corresponding to additional resources for timing error of the terminal device.

[0228] For example, the terminal device calculates the duration / minimum duration / maximum duration of the third time-frequency resource according to the indicated length information and the additional length information. The terminal device generates the second information only according to the indicated length information, and the terminal device does not generate the second information according to the additional length information, and only uses the additional length information to calculate the duration / minimum duration / maximum duration of the third time-frequency resource.

[0229] In some embodiments, the first information at least contains the related information of one or more third time-frequency resources, and / or the configuration information of the first time reference point and / or the second time reference point; wherein the related information of the plurality of third time-frequency resources is determined by a plurality of parameter groups; wherein the configuration information of the first time reference point and / or the second time reference point at least contains one of the following information: the serial number of the third time-frequency resource, the serial number of the parameter group.

[0230] For example, the configuration information of the first time reference point and / or the second time reference point is carried in the first information, and the first device indicates / configures the position of the first time reference point and / or the second time reference point on the time axis through the first information.

[0231] For example, the first device further indicates / configures which third time-frequency resource of the plurality of third time-frequency resources the first time reference point and / or the second time reference point corresponds to.

[0232] For example, the configuration information of the first time reference point and / or the second time reference point can further comprise one of the following: a sequence number of the third time-frequency resource, i.e., a sequence number of one third time-frequency resource in a plurality of third time-frequency resources determined by the first information; a sequence number of the parameter group, i.e., a sequence number of one third time-frequency resource in a parameter set for determining a plurality of third time-frequency resources by a plurality of parameter groups.

[0233] Thus, the related information of the third time-frequency resource can be determined according to the first information.

[0234] The following examples are given respectively:

[0235] As an example, the first device sends the first information to the terminal device, and the first information at least comprises the related information of one third time-frequency resource, wherein the related information of the one third time-frequency resource can be determined by one parameter group, for example, the one parameter group can refer to the related content of the aforementioned first time reference point / second time reference point and / or first time offset / second time offset and / or first time duration.

[0236] FIG. 5 is a schematic diagram of the first information and one third time-frequency resource according to an embodiment of the present application. As shown in FIG. 5, the first time reference point and the second time reference point are the same, and are the end position of the time-frequency resource (first time-frequency resource) where the first information is located, wherein the first time reference point is the start position of the third time-frequency resource after the first time offset, the second time reference point is the end position of the third time-frequency resource after the second time offset, or the end position of the third time-frequency resource after the first time duration after the first time offset.

[0237] As another example, the first device sends the first information to the terminal device, and the first information comprises the related information of a plurality of third time-frequency resources, wherein the related information of the plurality of third time-frequency resources can be determined by a plurality of parameter groups, and the specific content of each parameter group refers to the related content of the aforementioned first time reference point / second time reference point and / or first time offset / second time offset and / or first time duration.

[0238] FIG. 6 is a schematic diagram of the first information and a plurality of third time-frequency resources according to an embodiment of the present application. As shown in FIG. 6, the first time reference point and the second time reference point are the same, and are the end position of one third time-frequency resource, wherein the first time reference point is the start position of the next third time-frequency resource after the first time offset, the second time reference point is the end position of the next third time-frequency resource after the second time offset, or the end position of the next third time-frequency resource after the first time duration after the first time offset.

[0239] In some embodiments, the terminal device determines the start position and / or the end position of the second time-frequency resource according to the time interval.

[0240] For example, the time interval can be predefined in the communication standard, e.g., a definition of the above-mentioned time interval is given in the communication standard; and / or, the time interval can also be configured (e.g., through high layer signaling, etc.) and / or indicated (e.g., through physical layer signaling, etc.) by the first device for the terminal device.

[0241] In some embodiments, the time interval comprises at least one of: a time interval between the first signal and a second signal following the first signal, a time interval between the second signal and a first signal following the second signal, a time interval between two adjacent second signals.

[0242] For example, the time interval is a time interval (T1) between the first signal and a second signal following the first signal, wherein the time interval between the first signal and the second signal following the first signal can be at least a time interval between a last rising edge / falling edge of the first signal and a first rising edge / falling edge of the second signal.

[0243] For example, the time interval is a time interval (T2) between the second signal and a first signal following the second signal, wherein the time interval between the second signal and the first signal following the second signal can be at least a time interval between a last rising edge / falling edge of the second signal and a first rising edge / falling edge of the first signal.

[0244] For example, the time interval is a time interval (T3) between two adjacent second signals, wherein the time interval between the two adjacent second signals can be at least a time interval between a last rising edge / falling edge of a preceding second signal and a first rising edge / falling edge of a second signal following the preceding second signal.

[0245] In some embodiments, the time interval is related to a first time, which is at least related to a processing delay of the terminal device and / or a timing error of the terminal device.

[0246] For example, the first time is related to the processing delay of the terminal device; or, the first time is related to the timing error of the terminal device; or, the first time is related to both the processing delay of the terminal device and the timing error of the terminal device.

[0247] In some embodiments, the first time can be determined by a maximum sampling error of a terminal device supported by the system, or by the terminal device sending relevant information of a clock accuracy of the terminal device to the first device.

[0248] In some embodiments, the terminal device sends the first device information related to the local clock precision, and the clock precision related information at least includes one of the following: an initial sampling clock error; a corrected sampling clock error, wherein the corrected sampling clock error is at least a residual clock error after the terminal device synchronizes the first signal and corrects the initial clock error.

[0249] In some embodiments, the first time is determined at least by the maximum sampling error of the terminal device, or by the clock precision related information sent by the terminal device to the first device; and the time interval values of the time intervals correspond to different clock precisions and / or processing delays.

[0250] For example, the time interval values of the time intervals correspond to different clock precisions and / or processing delays, and the plurality of time interval values can also correspond to different terminal types, and the terminal device determines the time intervals according to its own type.

[0251] The following illustrates how the terminal device determines the start position and / or end position of the second time-frequency resource according to the time intervals in combination with different time interval types.

[0252] In some embodiments, the time intervals T1 and / or T3 are used to determine the start position of the second time-frequency resource.

[0253] For example, the time intervals T1 and / or T3 are used to determine the earliest start position of the second time-frequency resource; for another example, the time intervals T1 and / or T3 are used to determine the latest start position of the second time-frequency resource; for yet another example, the time intervals T1 and / or T3 are used to determine the earliest start position and the latest start position of the second time-frequency resource.

[0254] In some embodiments, the terminal device determines the start position of the second time-frequency resource according to at least the time intervals T1 and / or T3.

[0255] As an example, the terminal device determines the start position of the second time-frequency resource according to the time intervals T1 and / or T3. For example, the time intervals T1 and / or T3 indicate the start position of the second time-frequency resource, and the terminal device determines the start position of the second time-frequency resource according to the time intervals T1 and / or T3.

[0256] As another example, the terminal device determines the starting position of the second time-frequency resource according to at least the time interval T1 and / or T3. For example, the time interval T1 and / or T3 indicates an earliest starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the time interval T1 and / or T3 with reference to a timing error and / or processing timing of the terminal device. In this way, it is ensured that when the second signal carried by the second time-frequency resource reaches the network side, the starting time of the second signal is not earlier than the time indicated by the time interval T1 and / or T3, so that the network side can accurately receive the second signal.

[0257] As another example, the terminal device determines the starting position of the second time-frequency resource according to at least the time interval T1 and / or T3. For example, the time interval T1 and / or T3 indicates an earliest starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the time interval T1 and / or T3 with reference to a timing error and / or processing timing of the terminal device. In this way, it is ensured that when the second signal carried by the second time-frequency resource reaches the network side, the starting time of the second signal is not earlier than the time indicated by the time interval T1 and / or T3, so that the network side can accurately receive the second signal.

[0258] As another example, the terminal device determines the starting position of the second time-frequency resource according to at least the time interval T1 and / or T3. For example, the time interval T1 and / or T3 indicates an earliest starting position of the second time-frequency resource, and the terminal device determines the starting position of the second time-frequency resource according to the time interval T1 and / or T3 with reference to a timing error and / or processing timing of the terminal device. In this way, it is ensured that when the second signal carried by the second time-frequency resource reaches the network side, the starting time of the second signal is not earlier than the time indicated by the time interval T1 and / or T3, so that the network side can accurately receive the second signal.

[0259] In some embodiments, the time interval T2 is used to determine the ending position of the second time-frequency resource. For example, the time interval T2 is used to determine an earliest ending position of the second time-frequency resource; as another example, the time interval T2 is used to determine a latest ending position of the second time-frequency resource; and as yet another example, the time interval T2 is used to determine an earliest ending position and a latest ending position of the second time-frequency resource.

[0260] In some embodiments, the terminal device determines the ending position of the second time-frequency resource according to at least the time interval T2.

[0261] As an example, the terminal device determines the ending position of the second time-frequency resource according to the time interval T2. For example, the time interval T2 indicates the ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the time interval T2.

[0262] As another example, the terminal device determines the ending position of the second time-frequency resource according to at least a time interval T2. For example, the time interval T2 indicates an earliest ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the time interval T2 with reference to its timing error and / or processing timing, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, its ending time is not earlier than the time indicated by the time interval T2, so that the network side can accurately receive the second signal.

[0263] As another example, the terminal device determines the ending position of the second time-frequency resource according to at least a time interval T2. For example, the time interval T2 indicates an earliest ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the time interval T2 with reference to its timing error and / or processing timing, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, its ending time is not earlier than the time indicated by the time interval T2, so that the network side can accurately receive the second signal.

[0264] As another example, the terminal device determines the ending position of the second time-frequency resource according to at least a time interval T2. For example, the time interval T2 indicates an earliest ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource according to the time interval T2 with reference to its timing error and / or processing timing, etc. In this way, it can be ensured that when the second signal carried by the second time-frequency resource reaches the network side, its ending time is not earlier than the time indicated by the time interval T2, so that the network side can accurately receive the second signal.

[0265] In some embodiments, the terminal device determines the starting position and the ending position of the second time-frequency resource according to at least a time interval, for example similar to the foregoing embodiments, which will not be repeated here.

[0266] The following illustrates how the terminal device determines the frequency domain related information of the second time-frequency resource:

[0267] In some embodiments, the terminal device determines the frequency related information of the second time-frequency resource according to at least a second parameter; wherein the second parameter is determined by the first signal carrying and / or according to a predefined manner. In this way, even in the case that the frequency error of the frequency shift signal or carrier signal generated by the terminal device through the local crystal oscillator, circuit, etc. is large, the problem of how the terminal device determines the position of the second time-frequency resource in the frequency domain can be solved.

[0268] In some embodiments, the second parameter can be predefined in the communication standard, e.g., a definition of one or more than one parameter is given in the communication standard, and / or the second parameter can also be configured (e.g., by high layer signaling, etc.) and / or indicated (e.g., by physical layer signaling, etc.) by the first device for the terminal device. The second parameter contains one or more than one parameter.

[0269] For example, the second parameter is determined according to a predefined manner, e.g., the terminal device transmits the second signal on a frequency of the predefined second time-frequency resource.

[0270] Thus, the complexity of the terminal device can be reduced, and thus the cost of the terminal device can be reduced. For example, no frequency shifting device or circuit is needed on the terminal device.

[0271] For example, the second parameter is carried by the first signal, and the terminal device transmits the second signal on a frequency of the second time-frequency resource indicated / configured by the first device. Thus, the spectrum utilization of the system can be further improved.

[0272] In some embodiments, the terminal device determines the starting position, and / or the ending position, and / or the center frequency, and / or the bandwidth of the second time-frequency resource in the frequency domain according to the second parameter.

[0273] In some embodiments, the second parameter is used to determine the starting position of the second time-frequency resource in the frequency domain.

[0274] For example, the second parameter is used to determine the minimum starting position (the minimum frequency point of the starting position) of the second time-frequency resource in the frequency domain. For another example, the second parameter is used to determine the maximum starting position (the maximum frequency point of the starting position) of the second time-frequency resource in the frequency domain. For yet another example, the second parameter is used to determine the minimum starting position and the maximum starting position of the second time-frequency resource in the frequency domain.

[0275] In some embodiments, the terminal device determines the starting position of the second time-frequency resource in the frequency domain according to at least the second parameter.

[0276] As an example, the terminal device determines the starting position of the second time-frequency resource in the frequency domain according to the second parameter. For example, the second parameter indicates the starting position of the second time-frequency resource in the frequency domain, and the terminal device determines the starting position of the second time-frequency resource in the frequency domain according to the second parameter.

[0277] As another example, the terminal device determines the starting position of the second time-frequency resource in the frequency domain axis according to at least the second parameter. For example, the second parameter indicates a minimum starting position of the second time-frequency resource in the frequency domain axis, and the terminal device determines the starting position of the second time-frequency resource in the frequency domain axis according to the second parameter with reference to the frequency error of the terminal device. In this way, it is ensured that the spectral component of the second signal carried by the second time-frequency resource is not less than the minimum starting position of the second parameter in the frequency domain axis, so that the network side can accurately receive the second signal in frequency.

[0278] As another example, the terminal device determines the starting position of the second time-frequency resource in the frequency domain axis according to at least the second parameter. For example, the second parameter indicates a minimum starting position of the second time-frequency resource in the frequency domain axis, and the terminal device determines the starting position of the second time-frequency resource in the frequency domain axis according to the second parameter with reference to the frequency error of the terminal device. In this way, it is ensured that the spectral component of the second signal carried by the second time-frequency resource is not less than the minimum starting position of the second parameter in the frequency domain axis, so that the network side can accurately receive the second signal in frequency.

[0279] In some embodiments, the second parameter is used to determine the ending position of the second time-frequency resource in the frequency domain axis.

[0280] For example, the second parameter is used to determine the minimum ending position (the minimum frequency point of the ending position) of the second time-frequency resource in the frequency domain axis. As another example, the second parameter is used to determine the maximum ending position (the maximum frequency point of the ending position) of the second time-frequency resource in the frequency domain axis. As another example, the second parameter is used to determine the minimum ending position and the maximum ending position of the second time-frequency resource in the frequency domain axis.

[0281] In some embodiments, the terminal device determines the ending position of the second time-frequency resource in the frequency domain axis according to at least the second parameter.

[0282] As an example, the terminal device determines the ending position of the second time-frequency resource in the frequency domain axis according to the second parameter. For example, the second parameter indicates the ending position of the second time-frequency resource in the frequency domain axis, and the terminal device determines the ending position of the second time-frequency resource in the frequency domain axis according to the second parameter.

[0283] As another example, the terminal device determines the ending position of the second time-frequency resource in the frequency domain axis according to at least the second parameter. For example, the second parameter indicates a minimum ending position of the second time-frequency resource in the frequency domain axis, and the terminal device determines the ending position of the second time-frequency resource in the frequency domain axis according to the second parameter with reference to the frequency error of the terminal device. In this way, it is ensured that the spectral component of the second signal carried by the second time-frequency resource is not less than the minimum starting position of the second parameter in the frequency domain axis, so that the network side can accurately receive the second signal in frequency.

[0284] As a further example, the terminal device determines the ending position in the frequency domain axis of the second time-frequency resource according to the second parameter. For example, the second parameter indicates the maximum ending position of the second time-frequency resource, and the terminal device determines the ending position of the second time-frequency resource in the frequency domain axis according to the second parameter and the frequency error. Thus, it is ensured that the second signal spectrum carried by the second time-frequency resource is not greater than the maximum ending position in the frequency domain axis indicated by the second parameter, so that the network side can accurately receive the second signal in frequency.

[0285] In some embodiments, the second parameter is used to determine the starting position and the ending position of the second time-frequency resource in the frequency domain axis.

[0286] As an example, the second parameter indicates the bandwidth of the second time-frequency resource and / or the center frequency point of the second time-frequency resource. The terminal device determines the starting position and the ending position of the second time-frequency resource in the frequency domain axis according to the second parameter and the frequency error. Thus, it can be ensured that the second signal spectrum carried by the second time-frequency resource is within the bandwidth indicated by the second parameter.

[0287] As another example, the second parameter indicates the frequency domain resource unit identification / band identification / channel identification. The terminal device determines the starting position and the ending position of the second time-frequency resource according to the second parameter and the frequency error in combination with other related parameters about the frequency domain resource unit / band / channel. Thus, it can be ensured that the second signal spectrum carried by the second time-frequency resource is within the frequency domain resource unit / band / channel indicated by the second parameter, so that the network side can accurately receive the second signal in frequency.

[0288] In some embodiments, the second parameter is used to determine the center frequency point and / or the bandwidth of the second time-frequency resource in the frequency domain axis.

[0289] As an example, the second parameter indicates the bandwidth of the second time-frequency resource and / or the center frequency point of the second time-frequency resource. The terminal device determines the center frequency point and / or the bandwidth of the second time-frequency resource in the frequency domain axis according to the second parameter and the frequency error. Thus, it can be ensured that the second signal spectrum carried by the second time-frequency resource is within the bandwidth indicated by the second parameter.

[0290] As an example, the second parameter indicates the starting position and the ending position of the second time-frequency resource. The terminal device determines the center frequency point and / or the bandwidth of the second time-frequency resource in the frequency domain axis according to the second parameter and the frequency error. Thus, it can be ensured that the second signal spectrum carried by the second time-frequency resource is between the starting position and the ending position indicated by the second parameter.

[0291] As another example, the second parameter indicates a frequency domain resource unit identification / frequency band identification / channel identification. The terminal device determines the center frequency point and / or bandwidth of the second time-frequency resource according to the frequency error referred to, and according to the second parameter in combination with other related parameters about the frequency domain resource unit / frequency band / channel. In this way, it can be ensured that the spectrum of the second signal carried by the second time-frequency resource is located within the frequency resource unit / frequency band / channel indicated by the second parameter, so that the network side can accurately receive the second signal in frequency.

[0292] In some embodiments, the bandwidth of the second time-frequency resource contains the bandwidth of the second signal, and / or the bandwidth of the second time-frequency resource coincides with or is the same as the bandwidth of the second signal.

[0293] For example, the terminal device expects the bandwidth of the second time-frequency resource obtained through the second parameter to be no less than the bandwidth of the second signal itself sent by the terminal device; or the terminal device does not send the second signal on the frequency domain resource outside the bandwidth of the second time-frequency resource.

[0294] In this way, it can be ensured that the first device accurately receives the second signal.

[0295] The above only describes the steps or processes related to the present application, but the present application is not limited thereto. The method of the embodiments of the present application can also include other steps or processes, and the specific content of these steps or processes can be referred to the related art.

[0296] The above embodiments only exemplarily describe the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications can be made on the basis of the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0297] According to the embodiments of the present application, by determining the related information of the second time-frequency resource of the second signal related to the first signal, the first device can effectively perform interference coordination and management, and improve the spectrum utilization efficiency; and by determining the related information of the second time-frequency resource, the terminal device can cope with the timing error, so that the terminal device can make the transmitted second signal be completely received even if a low-cost local oscillator is used, and can avoid the collision of the second signal transmitted by the terminal device with other uplink signals or downlink signals, thereby improving the accuracy of signal reception or transmission, and improving the uplink coverage of the network.
