In this embodiment, the first part of the information is carried by RRC signaling and / or the first PDCCH, and the second part of the information is carried by the signal or the first PDCCH or the second PDCCH. In step 301, the terminal device may detect the signal and / Or the PDCCH and / or RRC signaling to receive the first part information and the second part information. For an unlicensed frequency band, the signal and the PDCCH can only be sent on a bandwidth available for sending the first data, and the terminal device according to the signal and / Or the PDCCH may also determine a bandwidth for sending the first data. Wherein, when the second part of the information is implicitly indicated by the signal or the first PDCCH, the correspondence between the second part of the information and the signal or the first PDCCH may be predefined or pre-configured by the network device to the terminal device, that is, the The method may further include: receiving, by the terminal device, the correspondence relationship sent by the network device.

In this embodiment, the method may further include (optional): Step 402: Determine the first resource according to the first part information and the second part information.

In this embodiment, for a specific implementation manner of the first part of information and the second part of information, reference may be made to Embodiment 1. The first part of the information and the second part of the information are the same or different or partially the same. On the one hand, When the first part of information is the same as the type of information in the second part of information, the second part of information can be regarded as update information of the first part of information, and the terminal device determines the first resource based on the information in the second part of information; On the one hand, when the first part of information is completely different from the information in the second part of information, the terminal device may determine the first resource based on the second part of information and the information in the first part of information. For example, the first resource Part of the information includes physical resource block or subcarrier information of the reference resource, and / or the symbol information of the reference resource corresponds to the frequency domain structure and / or time domain structure of the bandwidth unit, and the second portion of information includes an index of the bandwidth unit, Or, for example, the physical resource block or subcarrier information of the reference resource contained in the first part of the information, and / or the reference resource Information in the second part, the time / frequency domain starting position offset of the first resource relative to the reference resource, a multiple of the time domain length / frequency domain width, etc .; on the one hand, the information in the first part and the second part When the information types in the information are the same, the terminal device may determine the first information by combining the second information with the same information in the first information and the different information in the second information and the first information. Resources, such as the frequency domain starting position and / or frequency domain width of the reference resource contained in the first part of information, and the time domain length and time domain starting position of the reference resource, the second part of information contains the adjusted reference The frequency domain start position and / or frequency domain width of the resource, a multiple of the time domain length, the terminal device's adjusted frequency resource start position and / or frequency domain width included in the second information according to the second information, and the time domain The multiple of the length and the time domain length and the time domain start position of the reference resource in the first part of the information determine the first resource. The above is only an example, and this embodiment does not use this as an example. Not bore restrictions here.

In this embodiment, in step 403, the receiving may refer to the terminal device monitoring or detecting the first data on the first resource, which may be actually receiving the first data or may include not receiving the first data. . When it is determined in step 402 that the frequency domain position of the first resource is outside the current operating bandwidth of the terminal device (which will be described in Embodiment 5), before step 403, the method may further include (optional, not shown) ): The terminal device switches the working bandwidth. In step 403, after the terminal device switches the working bandwidth, it receives the first data sent by the network device on the first resource. Because it takes a certain time to switch the bandwidth, a reservation is required. The time interval ensures that the terminal device can receive data after the switching of the working bandwidth is completed.

As described in the Summary of the Invention, the inventor found that if the existing resource indication method is still used to indicate the resources used for downlink data transmission, it cannot flexibly adapt to the data transmission of new services, especially for network equipment that can be scheduled. When the bandwidth is changed, if the existing resource indication method is still used, spectrum resources may be wasted, and even downlink data may not be sent normally.

In order to solve the above problem, in addition to using the two pieces of information to indicate resources used for sending downlink data in the embodiments of the present invention, a resource indicating method is provided. After sending the downlink data, the network device sends The terminal device sends resources for downlink data transmission, so that it can more flexibly allocate and indicate resources for downlink data transmission, avoid waste of spectrum resources, and ensure normal transmission of downlink data.

Embodiment 3 of the present invention provides a resource indication method. FIG. 5 is a flowchart of a resource indication method in this embodiment, which is applied to a network device side. As shown in FIG. 5, the method includes:

Step 501: The network device sends the second data to the terminal device on the second resource.

Step 502: After sending the second data, the network device sends first indication information to the terminal device to indicate the second resource.

In this embodiment, for the meaning of the second resource and the second data, refer to Embodiment 1. The implementation of step 501 is similar to step 202 of embodiment 1, and details are not described herein again.

The specific information contained in the first indication information is similar to the first part of the information in Embodiment 1, and details are not described herein again.

In this embodiment, in order to conveniently indicate the second resource, the first instruction information further includes at least reference bandwidth information of the second resource.

Example 4

Embodiment 4 of the present invention provides a resource indication method, which is applied to a terminal device. The principle of this method to solve the problem is similar to that of Embodiment 3. Therefore, for specific implementation, refer to the implementation of the method of Embodiment 3. The content is the same. The description is not repeated here.

FIG. 6 is a flowchart of a resource indication method in this embodiment. As shown in FIG. 6, the method includes:

Step 601: The terminal device receives first indication information sent by the network device after sending the second data, where the first indication information is used to indicate second resource-related information;

Step 602: The terminal device receives the second data on the second resource.

In this embodiment, for the meaning of the second resource and the second data, refer to Embodiment 3, and details are not described herein again.

In this embodiment, in step 601, the terminal device performs monitoring and detection on its working bandwidth. After monitoring and detection, the terminal device determines that the network device sends the second data on the working bandwidth, but the terminal device does not know yet The specific resource location where the second data was sent, so the second data could not be received correctly. After determining that the network device sent the second data on the working bandwidth, after monitoring and detection, the terminal device can receive the The first indication information, for example, the terminal device blindly detects the PDCCH and demodulates the DCI in the PDCCH to receive the DCI, so as to determine the second resource according to the resource allocation information (first indication information) in the DCI, the first indication For a specific implementation manner of the information, refer to Embodiment 3, and details are not described herein again.

In this embodiment, in step 602, the terminal device receiving the second data on the second resource indicates that the terminal device demodulates the terminal device at a corresponding resource location (second resource) indicated by the first instruction information. Own physical downlink shared channel (PDSCH) to obtain downlink second data transmitted on the PDSCH and so on.

Currently, for unlicensed frequency bands, the availability of the channel cannot be guaranteed at all times. The bandwidth that can be used to transmit data may change over time. Therefore, if network equipment still makes scheduling decisions based on the original bandwidth, it may cause spectrum The waste of resources may even cause the downlink data not to be sent normally.

In order to solve the above problems, embodiments of the present invention further provide a method, an apparatus, and a communication system for adjusting resources, which can more flexibly allocate resources for sending downlink data, avoid waste of spectrum resources, and ensure normal transmission of downlink data.

Example 5

Embodiment 5 of the present invention provides a resource adjustment method. FIG. 7 is a flowchart of a resource indication method in this embodiment and is applied to a network device side. As shown in FIG. 7, the method includes:

Step 701: The network device performs channel evaluation on a channel on at least one carrier.

Step 702: The network device determines an available bandwidth that can be used to send third data according to a channel evaluation result.

Step 703: Allocate a third resource for the terminal device to send the third data on the available bandwidth.

In this embodiment, the network device may perform channel evaluation by using a frequency band of a predetermined length on at least one carrier as a basic frequency domain unit for channel evaluation. Hereinafter, the frequency band of the predetermined length is referred to as a bandwidth unit (BW unit). It can include multiple BW units, and the network device uses the BW unit as the basic frequency domain unit to perform channel evaluation, that is, perform channel evaluation on each BW unit, and the channel evaluation result determines whether each BW unit on the at least one carrier is Available. The BW unit can correspond to one or at least two operating channels, and each working channel can correspond to a nominal bandwidth of 20 MHz (NCB), or the BW unit can correspond to one or at least two first listen and then speak (LBT) or Clear Channel Assessment Channel (CCA) or subband, and the frequency domain position of the working channel or LBT / CCA subband / channel may be standard predefined.

In this embodiment, the BW unit described above can also be used as a basic frequency domain unit for data transmission, that is, a terminal device or a network device sends or receives data in one or more BW units. Figures 8A-8B are BW units on a carrier. Schematic diagram, as shown in Figures 8A-8B, where the number and size of BW units on each carrier can be the same or different, the size of multiple BW units on a carrier can be the same or different, and the location of BW units on each carrier The size and size may be predefined by the standard or preconfigured by the network device to the terminal device, which is not limited in this embodiment.

In this embodiment, in step 701, for example, a network device performs channel evaluation in units of BW units to determine whether a channel corresponding to each BW unit is idle. For example, when a channel energy value is lower than a threshold or a signal is not detected, The evaluation result is that the channel is idle, otherwise, the evaluation result is that the channel is busy.

In this embodiment, in step 702, the network device determines the available bandwidth that can be used to send the third data according to the channel evaluation result, that is, the evaluation result is one or at least two BW units corresponding to the channel idle as the available bandwidth. For a single carrier system, the available bandwidth is continuous. For a multi-carrier system, the available bandwidth can be continuous or non-continuous. The available bandwidth on each carrier is less than or equal to the carrier bandwidth of the corresponding carrier.

In this embodiment, in step 703, the network device may allocate the third resource to the terminal device according to the fourth resource allocated on the operating bandwidth of at least one carrier of the terminal device, that is, the network device according to the channel evaluation result Adjusting resource allocation, for example, adjusting the number of time domain symbols of the fourth resource, and / or the subcarrier interval, and / or the number of physical resource blocks or subcarriers, and / or the time / frequency domain starting position, and / or The carrier on which the fourth resource is located, thereby adjusting the fourth resource for downlink data transmission to a third resource, wherein the physical resource block of the fourth resource occupies a part (continuous or discontinuous) or all of the working bandwidth, This embodiment is not limited thereto.

In this embodiment, after a terminal device accesses a carrier, it can monitor or detect or receive downlink data at a predetermined bandwidth on the carrier. For example, the downlink data may be control information, signals, or data. The bandwidth is called the operating bandwidth. The operating bandwidth of a terminal device on a carrier can be pre-defined by the standard or pre-configured by the network device to the terminal device. The operating bandwidth on the carrier can be equal to the bandwidth of the carrier or the channel evaluation bandwidth. For example, when the network device informs the terminal device of the configuration of the downlink BWP, when the activated BWP is one, the working bandwidth may be the activated BWP, and when there are multiple activated BWPs, the operating bandwidth may be the largest among the activated BWPs. BWP, or the working bandwidth may also be the maximum BWP configured for the terminal device; for example, when the network device informs the terminal device about the bandwidth for channel evaluation, the working bandwidth of the terminal device may be the bandwidth for the channel evaluation, but this embodiment does not Use this as a limitation.

In this embodiment, in order to simplify resource allocation and channel evaluation, the working bandwidth on the one carrier may include one or at least two BW units, and the boundary of the working bandwidth is aligned with the boundaries of the BW units, but this embodiment does not With this as a limitation, the boundary of the working bandwidth may not be aligned with the boundary of the BW unit. The configuration of the BW unit is cell-specific or UE-specific. 9A-9C are schematic diagrams of the working bandwidth of a BW unit on a carrier and various terminal devices. As shown in FIG. 9A, the working bandwidth of terminal device 1 corresponds to one BW unit, and the working bandwidth of terminal device 2 corresponds to two BW units, and As shown in FIG. 9B, the working bandwidth of terminal device 1 corresponds to one BW unit, and the working bandwidth of terminal device 2 corresponds to one BW unit, and they do not overlap each other, but the BW units corresponding to the two terminal devices have different sizes. As shown in FIG. 9C, the operating bandwidth of terminal device 1 corresponds to 3 BW units, the operating bandwidth of terminal device 2 corresponds to 1 BW unit, and the operating bandwidth of terminal device 3 corresponds to 1 BW unit, and there is overlap, and terminal device 2, 3 The corresponding BW unit sizes are different.

The following specifically explains how to adjust the fourth resource to a third resource.

In one embodiment, the network device adjusts the number of time domain symbols of the fourth resource according to the channel evaluation result to obtain the third resource. In this embodiment, the available bandwidth is within the working bandwidth of the terminal device, and the terminal device does not need to Switch or adjust the working bandwidth, and adjust the number of time-domain symbols of the fourth resource within the available bandwidth. It should be noted that during the adjustment, in order to ensure the normal transmission of data, the number of time-frequency resource blocks included in the third resource It is substantially the same as the number of time-frequency resource blocks included in the fourth resource. 10A-10B are schematic diagrams of adjusting the number of symbols in the time domain of the fourth resource. As shown in FIG. 10A-10B, after the channel assessment, if at least one physical resource block of the fourth resource is not within the available bandwidth, the working bandwidth needs to be adjusted. The number of time-domain symbols of the fourth resource is increased so that the number of time-frequency resource blocks included in the third resource is approximately the same as the number of time-frequency resource blocks included in the fourth resource. Based on the increased bandwidth, The number of time-domain symbols determines the third resource, that is, the number of time-domain symbols of the fourth resource and the third resource are different. The number of time-domain symbols can be determined according to the available bandwidth and the ratio of the operating bandwidth, where the physical resource block of the third resource accounts for A part (continuous or discontinuous) or all of the available bandwidth is illustrated in FIG. 10B by taking the physical resource block of the third resource occupying the entire available bandwidth as an example, but this embodiment is not used as a limitation.

In one embodiment, the network device adjusts the subcarrier interval according to the channel evaluation result to obtain a third resource. In this embodiment, the available bandwidth is within the operating bandwidth of the terminal device, and the terminal device does not need to switch or adjust the operating bandwidth. To adjust the subcarrier interval of the fourth resource within the available bandwidth, it should be noted that during the adjustment, in order to ensure the normal transmission of data, the number of time-frequency resource blocks included in the third resource and the fourth resource include The number of time-frequency resource blocks is approximately the same. 11A-11B are schematic diagrams for adjusting the subcarrier interval of the fourth resource. As shown in FIG. 11A-11B, after the channel assessment, if at least one physical resource block of the fourth resource is not within the available bandwidth, the fourth bandwidth in the working bandwidth needs to be The subcarrier interval of the resource is reduced. In the available bandwidth, the third resource is determined according to the adjusted subcarrier interval, that is, the subcarrier interval of the fourth resource is different from that of the third resource. The working bandwidth ratio is determined, in which the physical resource block of the third resource occupies a part (continuous or discontinuous) or all of the available bandwidth. FIG. 11B uses the physical resource block of the third resource to occupy the entire available bandwidth as an example. This embodiment is not limited thereto.

In one embodiment, the network device adjusts the number of physical resource blocks or the number of subcarriers according to the channel evaluation result to obtain a third resource. In this embodiment, the available bandwidth is within the working bandwidth of the terminal device, and the terminal device does not need to Switch or adjust the working bandwidth, and adjust the number of physical resource blocks or subcarriers of the fourth resource within the available bandwidth. It should be noted that in this adjustment method, the physical resource block of the third resource is included in the fourth resource. The physical resource blocks in the available bandwidth have the same number of time-domain symbols, so the number of time-frequency resource blocks included in the third resource and the number of time-frequency resource blocks included in the fourth resource may not remain approximately the same. When data is transmitted, the third resource may only carry part of the data. In order to reduce retransmission, when the complete data corresponds to one transport block, part of the transmitted data may correspond to one or more code blocks of one transport block or Code block group. 12A-12B are schematic diagrams of adjusting the number of physical resource blocks or subcarriers of the fourth resource. As shown in FIG. 12A-12B, after the channel assessment, if at least one physical resource block of the fourth resource is not within the available bandwidth, it will work. The number of physical resource blocks or subcarriers of the fourth resource on the bandwidth is reduced. On the available bandwidth, the third resource is determined according to the adjusted number of physical resource blocks or subcarriers, that is, the physical resource blocks of the fourth resource and the third resource. Or the number of subcarriers is different, in which the physical resource block of the third resource occupies a part (continuous or discontinuous) or all of the available bandwidth, FIG. 12B uses the physical resource block of the third resource to occupy the entire available bandwidth as an example. However, this embodiment is not limited thereto.

In one embodiment, the network device adjusts the time / frequency domain starting position according to the channel evaluation result to obtain a third resource. In this embodiment, the available bandwidth does not completely overlap the working bandwidth of the terminal device, and the terminal device needs Switch or adjust the working bandwidth, and adjust the time / frequency domain starting position of the fourth resource within the available bandwidth. It should be noted that, in order to ensure the normal transmission of data, the number of time-frequency resource blocks included in the third resource and The number of time-frequency resource blocks included in the fourth resource is substantially the same. 13A-13B are schematic diagrams of adjusting the starting position of the fourth resource in the frequency domain. As shown in FIG. 13A-13B, after the channel evaluation, the available bandwidth is similar to the working bandwidth, but does not completely overlap the working bandwidth of the terminal device. The terminal device needs to switch or adjust the operating bandwidth 1 to the operating bandwidth 2. The starting position of the frequency domain of the fourth resource on the operating bandwidth 1 needs to be adjusted to the lowest position in the frequency domain of the available bandwidth. The start position in the frequency domain determines the third resource, that is, the start position in the frequency domain of the fourth resource is different from the third resource. The physical resource block of the third resource occupies a part (continuous or discontinuous) or all of the available bandwidth. FIG. 13B takes all the available bandwidth occupied by the physical resource blocks of the third resource as an example, but this embodiment is not used as a limitation.

In an implementation manner, the network device adjusts a carrier where the fourth resource is located according to a channel evaluation result to obtain a third resource. Figure 10-13 above uses a single carrier as an example to explain how to adjust the fourth resource, but it should be noted that the adjustment of the fourth resource can also be cross-carrier. The difference from the single carrier is that due to the availability of multiple carriers The bandwidth may be discontinuous, so the third resource may also be discontinuous in the frequency domain. In this embodiment, the available bandwidth does not overlap with the working bandwidth of the terminal device, or does not completely overlap. The terminal device needs to switch or adjust the working bandwidth, and adjust the carrier where the fourth resource is located within the available bandwidth of multiple carriers. . Figures 14A-14B are schematic diagrams of adjusting carriers. As shown in Figures 14A-14B, after channel evaluation, the available bandwidth is distributed on a part of the bandwidth of the second carrier and the third carrier, which does not completely overlap the operating bandwidth of the terminal device. The carrier on which the fourth resource in the working bandwidth is located is adjusted to a part of the bandwidth of the second carrier and the third carrier. In the available bandwidth, the third resource is determined according to the adjusted carrier, where the physical resource block of the third resource It occupies a part (continuous or discontinuous) or all of the available bandwidth. FIG. 14B uses the physical resource block of the third resource to occupy the entire available bandwidth as an example, but this embodiment is not used as a limitation.

Among them, to simplify the adjustment method and instructions, optionally, if the physical resource blocks in the fourth resource are distributed to at least two BW units in the UE operating bandwidth, the physical resource blocks in the fourth resource are in the at least two BWs. The units are evenly distributed, and the physical resource block locations in each BW unit are the same.

It should be noted that the above-mentioned several resource adjustment methods can be performed independently or in combination with at least two adjustment methods. This embodiment is not used as a limitation. For example, two parameters such as the number of time domain symbols and the subcarrier interval can be adjusted and determined. The third resource is no longer an example here.

In this embodiment, the foregoing several resource adjustment methods are similar to the resource mapping method described in Embodiment 1 (the working bandwidth in resource adjustment corresponds to the reference bandwidth in resource mapping, and the two may be the same or different), that is, The mapping manner of the first resource to the reference resource includes: adjusting the number of time domain symbols and / or subcarrier intervals and / or the number of physical resource blocks and / or the number of subcarriers and / or the time / frequency domain start position and / Or the carrier on which the reference resource is located to obtain the first resource, the second part of information may use a predetermined number of bits to indicate the mapping method, for example, 3 bits are used to indicate the mapping method, and the second part of the information includes "000" Indicates that the mapping method of the first resource to the reference resource is to adjust the number of symbols in the time domain. When the second part of the information includes "001", it indicates that the mapping method of the first resource to the reference resource is to adjust the subcarrier interval. For example, the specific adjustment value of the mapping mode (such as the number of adjusted symbols or the interval of subcarriers or the number of physical resource blocks or the number of subcarriers) may be predefined by the standard, or Pre-configured by the network device to the terminal device, or a network device may be the specific adjustment value together as the mapping mode terminal device sends information to the second portion, the present embodiment is not limited thereto.

For implementation of this step, refer to step 201 in Embodiment 1 or step 502 in Embodiment 3. For the implementation manner, reference may be made to the indication information in Embodiment 1 or the first indication information in Embodiment 3, and details are not described herein again. The difference from Embodiment 1 or 3 is that, for a multi-carrier system, the second indication information may further include a carrier index where the fourth resource and / or the third resource are located.

In this embodiment, the method may further include: (not shown, optional)
