Abstract
Description
Technical Field
[0001] This application relates to the field of communications, and more specifically, to methods and apparatuses for resource indication in the field of communications. Background Art
[0002] Due to the development of communication systems and industry requirements, the available spectrum resources are discontinuous in spectrum resource allocation. In some scenarios, the bandwidth of each discrete frequency point is small, and only low-rate access can be provided, which cannot meet the communication requirements of high-speed data services. Discrete narrowband communication technology is a narrowband aggregation system designed for discontinuous spectrum resources, that is, multiple discontinuous narrowband spectrums on broadband spectrum are aggregated for use. Through discrete narrowband communication technology, the broadbandization of discrete narrowband resources can be achieved, the bandwidth capacity of the terminal can be increased, and the requirements of high-speed data services can be met.
[0003] In a discrete narrowband cellular communication system during scheduling, the more narrowband spectrums are aggregated, the higher the transmission rate will be. In the existing discrete carrier aggregation air interface protocol, physical carriers are mapped to logical carrier indexes one by one in ascending order. Resource allocation is scheduled based on logical carrier indexes. When the access network device performs resource scheduling, the start position and number of logical carriers for data transmission or reception are indicated in the control information. Therefore, when a certain carrier has a large interference, the access network device does not want to use this carrier for data transmission or reception. However, the logical carrier resources are continuously allocated. Not scheduling the carrier with large interference results in discontinuous available logical carriers, thus limiting the number of continuously scheduled carriers, and further reducing the data transmission rate. Summary of the Invention

Optionally, the first logical frequency-domain resource index corresponds, in descending order, to the physical frequency-domain resources with increasing channel quality among the first physical frequency-domain resources. With this resource mapping method, since resources with similar channel quality are scheduled together, it is beneficial to use physical resources with high channel quality for data transmission or reception, thereby improving the data rate of the entire system.

[0050] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Before explaining the technical solutions in the embodiments of the present application, the application scenarios in the embodiments of the present application will be described in conjunction with the accompanying drawings first.
[0051] First, to facilitate the understanding of the present application, the basic concepts involved in the present application will be introduced below.
[0052] Discrete Spectrum Aggregation: Due to the development of communication systems and industry requirements, spectrum resources are divided. Among them, the bandwidth of each frequency point in the discrete spectrum is relatively small, and only low-rate access can be provided. If the terminal uses the discrete spectrum to communicate with the access network device (such as a base station), it cannot meet the communication requirements of the terminal's high-speed data services. To meet the communication requirements of the terminal's high-speed data services, the carrier aggregation (CA) technology (or discrete narrowband communication technology) is proposed. For example, two or more discrete carrier units (component carriers, CCs) are aggregated and allocated to the terminal to support the terminal in transmitting data services on a larger transmission bandwidth and meet the communication requirements of high-speed data services.
[0053] Absolute physical carrier index: The index of the physical frequency point itself. One absolute physical carrier index corresponds to one physical carrier (or one frequency-domain physical resource).
[0054] Logical carrier index: The carrier number, and there is a one-to-one correspondence (or one-to-one mapping) between the logical carrier index and the absolute physical carrier index (or physical carrier or frequency-domain physical resource).
[0055] Absolute physical carrier index: A frequency-domain physical resource (or a frequency-domain physical resource unit) can be a physical resource block (PRB) in the frequency domain. For example, in the LTE system, one PRB occupies 12 subcarriers. A frequency-domain physical resource can also be a carrier. For example, a frequency-domain physical resource is a carrier in a narrowband system. In the power private network system, the bandwidth of one carrier is 25 kHz. That is to say, a frequency-domain physical resource can be a carrier in the available carriers of the narrowband system.
[0056] Carrier based frequency hopping: Frequency hopping based on a single carrier. The basic unit of frequency hopping is the carrier.
[0057] Carrier-group based frequency hopping: Frequency hopping based on a group of carriers. A group of carriers includes multiple carriers. For example, a group of carriers has 3 carriers. The basic unit of frequency hopping is a group of carriers.
[0058] Time unit: In this application, the length of one time unit can be set arbitrarily and is not limited here.
[0059] For example, one time unit may include one or more subframes.
[0060] Alternatively, one time unit may include one or more time slots.
[0061] Alternatively, one time unit may include one or more mini time slots.
[0062] Alternatively, one time unit may include one or more symbols.
[0063] Alternatively, one time unit may include one or more Transmission Time Intervals (TTIs).
[0064] Alternatively, one time unit may include one or more short Transmission Time Intervals (sTTIs).
[0065] Alternatively, one time unit may correspond to a time pattern. For example, the first time pattern is a transmission time interval of 2 symbols or 3 symbols, and the second pattern is a transmission time interval of 7 symbols.
[0066] Wherein, a mini time slot includes one or more symbols, and the mini time slot is less than or equal to a time slot. Here, the time slot can be a mini time slot in a system with a 60 kHz subcarrier spacing, or a mini time slot in a system with a 15 kHz subcarrier spacing. The embodiments of the present invention do not make any restrictions.
[0067] Wherein, a time slot includes one or more symbols. Here, the time slot can be a time slot in a system with a 60 kHz subcarrier spacing, or a time slot in a system with a 15 kHz subcarrier spacing. The embodiments of the present invention do not make any restrictions.
[0068] Wherein, TTI is a parameter commonly used in current communication systems (for example, Long Term Evolution (LTE) systems), and it refers to the scheduling unit for scheduling data transmission in a wireless link. In LTE, it is generally considered that 1 TTI = 1 ms. That is, one TTI is the size of one subframe or, in other words, two time slots. It is the basic unit of the time governed by radio resource management (scheduling, etc.). In the power wireless private network system, currently, it supports a 25 kHz carrier spacing in the 230M frequency band in China, and one TTI is one frame (there are two frame structures, 10 ms and 20 ms).
[0069] Channel quality: Channel quality is a way to evaluate the attenuation of the channel between communication parties on the signal. Channel quality is also a way for the receiving party to evaluate whether the received signal is "good" or "bad". Channel quality can be expressed as the reference signal received power (RSRP), the reference signal received quality (RSRQ), the channel quality information (CQI) measured by the terminal device, or the received interference power (RIP Interference Power) value of the physical carrier, the signal-to-noise ratio, the signal-to-interference-plus-noise ratio, etc.
[0070] Frequency-domain physical resources are interleaved in the frequency domain: The frequency-domain physical resources of two sets are interleaved in the frequency domain. However, the frequency-domain physical resources of these two sets do not overlap. For example, the frequency points (frequencies of the carriers) of the physical resources of the first set are 1, 3, 7 (unit: MHz); the frequency points of the physical resources of the second set are 2, 10, 11. That is to say, at least one frequency point of at least one set is between the lowest frequency point and the highest frequency point of the other set. The frequency point 2 of the second set is between the lowest frequency point 1 and the highest frequency point 7 of the first set.
[0071] The x-th frequency-domain resource logical index, the x-th frequency-domain physical resource (x is a positive integer): The x-th frequency-domain resource logical index represents one or more frequency-domain resource logical indices; the x-th frequency-domain physical resource represents one or more frequency-domain physical resources (or frequency-domain physical resource units). For example, the first frequency-domain resource logical index represents one or more frequency-domain resource logical indices.
[0072] Access network device: The access network device can be an access network equipment or a chip in the access network equipment. Hereinafter, the access network device is taken as an example of the access network equipment to describe the embodiments.
[0073] Terminal device: The terminal device can be a terminal equipment or a chip in the terminal equipment. Hereinafter, the terminal device is taken as an example of the terminal equipment to describe the embodiments.

For example, if the bandwidth of each carrier is 1 MHz and the starting frequency of physical carrier index 1 is 2 GHz. Then the frequency-domain resource corresponding to physical carrier index 1 is from 2G to 2G + 1 MHz; the frequency-domain resource corresponding to physical carrier index 2 is from 2G + 1 MHz to 2G + 2 MHz; and so on, and the frequency-domain resource corresponding to physical carrier index 20 is from 2G + 19 MHz to 2G + 20 MHz.
[0092] When the operator or enterprise network deploys the network, it is determined that the physical carrier indices 6, 7, 11, 12, 15, 16 are unavailable for the access network device. One reason for the unavailability of the above physical carrier indices is that the physical carriers corresponding to the above physical carrier indices are not allocated to the communication network to which the access network device belongs. For example, if the communication network is an enterprise network, the physical carriers corresponding to the physical carrier indices 6, 7, 11, 12, 15, 16 are not allocated to this enterprise. In Figure 2 the second row, an effective carrier of 1 indicates that the physical carrier index is available, and an effective carrier of 0 indicates that the physical carrier index is unavailable. Figure 2The third row gives the correspondence between the logical carrier index or the physical channel index after removing the carriers where the access network device is unavailable. For example, the logical carrier index 6 corresponds to the physical carrier index 8.
[0093] When the interference on the physical carriers corresponding to the physical carrier indices 3, 8, 10, and 18 is relatively large (equivalent to poor channel quality or signal reception quality), the access network device does not wish to communicate with the terminal device on the physical carriers corresponding to the physical carrier indices 3, 8, 10, and 18. Moreover, when the access network device performs resource scheduling, it allocates consecutive logical carrier indices. In this case, in order to avoid the physical carriers corresponding to the physical carrier indices 3, 8, 10, and 18 during scheduling, for the logical carrier indices 1 - 8, it is not possible to allocate 3 or more carriers at one time.
[0094] To solve the above problems, Figure 3 A flowchart showing the access network device receiving data from the terminal device is given. In Figure 3 Taking one frequency - domain physical resource unit as one carrier as an example. In this case, the logical index of the frequency - domain resource is the logical carrier index.
[0095] In step 301, the access network device sends the one - to - one correspondence between the first logical index of the frequency - domain resource and the first frequency - domain physical resource to the terminal device. The frequency - domain physical resources corresponding to different logical indices of the frequency - domain resources are different. Refer to Figure 2 The first frequency - domain physical resource is the carrier corresponding to the physical carrier indices 1 - 5, 8 - 11, 14, 17 - 19.
[0096] The first logical index of the frequency - domain resource includes a first set and a second set. The logical indices of the frequency - domain resources included in the first set are consecutive indices, and the logical indices of the frequency - domain resources included in the second set are consecutive indices. That is to say, the logical indices of the frequency - domain resources included in the first set and the second set are all consecutive indices. The frequency - domain physical resources corresponding to the logical indices of the frequency - domain resources in the first set and the frequency - domain physical resources corresponding to the logical indices of the frequency - domain resources in the second set are interleaved in the frequency domain. Any logical index of the frequency - domain resources included in the first set is different from any logical index of the frequency - domain resources included in the second set.
[0097] For example, the channel quality of the frequency - domain physical resources corresponding to any logical index of the frequency - domain resources included in the first set is lower than the threshold value; the channel quality of the frequency - domain physical resources corresponding to any logical index of the frequency - domain resources included in the second set is not lower than the threshold value. Figure 4 The correspondence between the logical index of the frequency - domain resource and the index of the frequency - domain physical resource is given. Since the index of the frequency - domain physical resource and the frequency - domain physical resource are in one - to - one correspondence, Figure 4 The correspondence between the logical index of the frequency - domain resource and the frequency - domain physical resource is also given. Figure 4 Based onFigure 2 , in Figure 4 , only the valid carriers are drawn. Figure 4 The first line of Figure 2 is similar and will not be elaborated here. Figure 4 The second line of Figure 5 represents the channel quality. "1" indicates that the measured channel quality is high or good; "0" indicates that the channel quality is low or poor. Figure 5 An example of the access network device determining the channel quality of the frequency-domain physical resources before step 301 is given.
[0098] In step 501, the access network device receives a reference signal from the terminal device. The reference signal can be a sounding reference signal (SRS).
[0099] In step 502, the access network device measures the signal reception quality according to the reference signal. For example, in the valid physical carriers, the channel quality of the physical carriers with physical carrier indices 1, 2, 4, 5, 9, 11, 14 is evaluated as high, and the channel quality of the physical carriers with physical carrier indices 3, 8, 10, 18 is evaluated as low. Taking the signal reception quality as RIP as an example, it is equivalent that the physical carriers with physical carrier indices 3, 8, 10, 18 have relatively large interference and are the physical carriers that the access network device does not want to schedule.
[0100] As Figure 4 shown, the logical carrier indices corresponding to the physical carrier indices 3, 8, 10, 18 are consecutive indices (belonging to the first set); the logical carrier indices corresponding to the physical carrier indices 1, 2, 4, 5, 9, 11, 14 are consecutive indices (belonging to the second set). The first frequency-domain resource logical index is Figure 4 the logical carrier indices 1 - 13 in
[0101] For the correspondence between the physical carrier index and the logical carrier index of the access network device, there can be the following several ways: Way 1: The access network device classifies the physical carriers into the first set or the second set according to the physical carrier signal reception quality, and the physical carrier index and the logical carrier index within the first set or the second set are randomly corresponding.
[0102] For example, the physical carriers with RIP measured by the access network device higher than 10 dB are the second set, such as Figure 4 the physical carrier indices 3, 8, 10, 18 in Figure 4 ; the physical carriers with RIP measured by the access network device less than or equal to 10 dB are the first set. As
[0103] Method 2: The access network device sorts the physical carrier signal reception quality from high to low. That is, the first frequency-domain resource logical index corresponds one by one to the frequency-domain physical resources with the channel quality from high to low in the first frequency-domain physical resource in the order from low to high.
[0104] For example, the RIP measured by the access network device is sorted from low to high in value, and its corresponding logical carrier index is numbered from low to high. As Figure 4 shown, the RIP value of the physical carrier with physical carrier index 1 is the lowest, and the RIP value of the physical carrier with physical carrier index 18 is the highest.
[0105] Among them, the last 4 physical carriers corresponding to the logical carrier index are carriers with relatively large interference (poor channel quality), and the access network device does not want to schedule these 4 physical carriers to communicate with the terminal device.
[0106] Method 3: The access network device sorts the physical carrier signal reception quality from low to high. Method 3 can refer to Method 2 and will not be elaborated here. For the mapping method of Method 2 or 3, since the resources with close channel quality are scheduled together, it is beneficial to use the physical resources with high channel quality for data transmission or reception, thereby improving the data rate of the entire system.
[0107] For the above mapping method, when the access network device performs resource scheduling through continuous logical carrier indexes, more resources can be allocated, thereby improving the terminal transmission rate, reducing the terminal transmission delay, and improving the spectrum resource utilization rate.
[0108] In a possible design, the access network device and the terminal device communicate through a frequency hopping method. That is, the access network device receives data on the second frequency-domain physical resource through a frequency hopping method. Frequency hopping is an important means of randomizing interference. Frequency hopping includes single-carrier frequency hopping and group frequency hopping. In single-carrier frequency hopping, the same logical carrier is mapped to (or corresponds to) different physical carriers in different time units. A frequency-domain hopping unit of single-carrier frequency hopping is a frequency-domain physical resource. For example, the logical carrier with logical carrier index 1 is mapped to the physical carrier with physical carrier index 1 in the first time unit; in the second time unit, this logical carrier is mapped to the physical carrier with physical carrier index 13.
[0109] For group frequency hopping, a set of logical carriers are mapped to different physical carriers in different time units. A frequency-domain hopping unit of group frequency hopping is multiple frequency-domain physical resources. For example, a set of logical carriers with logical carrier indices 1 and 2 are mapped to physical carriers with physical carrier indices 1 and 2 respectively in the first time unit. In the second time unit, the logical carriers with logical carrier indices 1 and 2 are mapped to physical carriers with physical carrier indices 13 and 14 respectively. Among them, the relevant parameters of a set of carriers in group frequency hopping can be predefined according to product requirements. The access network device can also send the relevant parameters to the terminal device through signaling. For example, if the RF (Radio Frequency) bandwidth of the product terminal is relatively small, a set of carriers in group frequency hopping can be defined as a set of consecutive physical carriers, and the number of carriers in a set is 4.
[0110] When in a time unit, single carrier frequency hopping and group frequency hopping exist simultaneously in a cell. The effective carriers in the system first form the resources of the group frequency hopping carriers. The remaining carriers that are not group frequency hopping carriers serve as the single carrier frequency hopping carrier resources. Figure 6 The schematic diagrams of group frequency hopping and single carrier frequency hopping are given. As Figure 6 shown, a set of carriers in group frequency hopping is 4 consecutive physical carriers. Since Figure 6 physical carrier indices 6, 7, 12, 13, 15, 16, 20 are invalid carriers among the physical carrier indices 1 - 20, only 1 - 4 and 8 - 11 can form two hopping groups. Physical carrier indices 1 - 4 form one hopping group, and 8 - 11 form another hopping group. The remaining physical carrier indices 5, 14, 17 - 19 are used for single carrier frequency hopping. Figure 6 The group frequency hopping size in Figure 6 is the number of consecutive physical carriers included in a hopping group. In Figure 6 the effective carriers are divided into group frequency hopping carrier resources and single carrier frequency hopping carrier resources. Figure 6 The group frequency hopping carriers corresponding to the logical carrier indices in Figure 6 are interleaved (or coexist with intervals) with non-group frequency hopping carriers. When the access network device performs resource scheduling, since the resource allocation indication is for continuous resource allocation (continuous logical carrier indices), and single carrier frequency hopping carriers and group frequency hopping carriers cannot be used in combination, the number of continuously allocated resources (number of carriers) will be limited. For example, in Figure 6 assuming the access network device allocates single carrier frequency hopping resources to terminal device A. Logical carrier index 5 (physical carrier index 5) cannot be allocated together with logical carrier indices 10 - 13. In another example, see Figure 6, the access network device allocates group hopping carrier resources to the terminal device B. Similarly, since there is a single carrier hopping resource (logical carrier index 5) between the first group hopping carrier resource (logical carrier indices 1 - 4) and the second group hopping carrier resource (logical carrier indices 6 - 9), the access network device cannot allocate these two groups at once for the terminal device B to perform data transmission. This results in limited carrier data that can be scheduled at one time and a reduced carrier utilization rate.
[0111] Figure 7 Based on Figure 6 , in Figure 7 , in the case where there are both group hopping and single carrier hopping simultaneously, a schematic diagram of the mapping from logical carrier index to physical carrier. Figure 7 Only the valid carriers are drawn. Figure 7 The first and second rows of Figure 6 are similar and will not be elaborated further. Any frequency domain physical resource corresponding to a frequency domain resource logical index included in the second set belongs to the frequency domain physical resource of single carrier hopping; any frequency domain physical resource corresponding to a frequency domain resource logical index included in the first set belongs to the frequency domain physical resource of group hopping. In Figure 7 , the frequency domain resource logical indices in the first set are the logical carrier indices of the group hopping carriers, with indices 1 - 8; the frequency domain resource logical indices in the second set are the logical carrier indices of the single carrier hopping, with indices 9 - 13. With this mapping method, when the access network device performs continuous resource scheduling for the terminal device, more resources can be scheduled, thereby improving the terminal transmission rate, reducing the terminal transmission delay, and increasing the spectrum resource utilization rate.
[0112] In step 302, the access network device sends indication information to the terminal device. This indication information indicates the second frequency domain resource logical index, where the first set includes the second frequency domain resource logical index or the second set includes the second frequency domain resource logical index. The second frequency domain resource logical indices are consecutive indices, and the second frequency domain resource logical indices correspond one - to - one with the second frequency domain physical resources.
[0113] This indication information indicates the frequency domain resource logical index of the data to be received. The frequency domain resource logical index of the data to be received corresponds to the frequency domain physical resource of the data to be received. The frequency domain resource logical indices of the data to be received are consecutive indices. For example, this indication information is carried in the scheduling signaling. The frequency domain physical resources of the data to be received are discontinuous physical resources.
[0114] Taking Figure 4 as an example, this indication information indicates that the starting logical carrier index is 2 and the number of logical carrier indices is 5. The second frequency domain resource logical indices are logical carrier indices 2 - 6. Then, after receiving it, the terminal device sends data on the physical carriers (physical carrier indices are 2, 4, 5, 9, 11) corresponding to logical carrier indices 2 - 6.
[0115] Taking the group frequency hopping in Figure 7 as an example, the indication information indicates the starting carrier logical index 1 and has a length of 4. The second frequency-domain resource logical index is the logical carrier index from 1 to 4, corresponding to the physical carrier index from 1 to 4. After receiving it, the terminal device (e.g., terminal device B) sends data on the physical carriers with physical carrier indices from 1 to 4.
[0116] If the terminal device receives the indication information in the k-th time unit, the terminal device can send data in the (k + p)-th time unit, where p is a positive integer.
[0117] In step 303, the access network device receives data from the terminal device.
[0118] The access network device receives data from the terminal device on the second frequency-domain physical resource. Taking Figure 4 as an example, referring to step 302, the access network device receives data from the terminal device on the physical carriers with physical carrier indices 2, 4, 5, 9, and 11. Taking Figure 7 as an example, referring to step 302, the access network device receives data from the terminal device (e.g., terminal device B) on the physical carriers with physical carrier indices from 1 to 4.
[0119] Figure 8 The flowchart for the access network device to send data to the terminal device is given. Figure 8 and Figure 3 The main difference is that in Figure 3 , it is uplink data transmission; in Figure 8 , it is downlink data transmission. The following mainly describes the differences between Figure 8 and Figure 3 .
[0120] Step 801, referring to step 301, will not be elaborated further.
[0121] Step 802, in 802, the frequency-domain resource logical index indicated by the indication information sent by the access network device is used to notify the terminal device for receiving downlink data. The terminal device determines the physical resources for receiving data according to this indication information. For specific details, refer to step 302, and change the terminal device sending data in step 302 to the terminal device receiving data (equivalent to the difference between 803 and 303).
[0122] Step 803, the access network device sends data to the terminal device.
[0123] The terminal device receives data from the access network device on the frequency-domain physical resources determined in step 802.
[0124] Regarding logical resource index, physical resource index, single-carrier frequency hopping, group frequency hopping, etc., refer toFigure 3 the description in
[0125] Figure 9 Examples of the access network device receiving the downlink channel quality sent by the terminal device before step 801 are given.
[0126] In step 901, the access network device sends a reference signal to the terminal device. The reference signal can be a channel state information (CSI) reference signal.
[0127] The terminal device measures the downlink channel quality based on the reference signal.
[0128] In step 902, the terminal device sends the channel quality to the access network device. For example, the terminal device sends a channel quality indication (CQI) to the access network device. The CQI is used to represent the downlink channel quality. The access network device can determine the correspondence between the logical carrier index and the physical carrier index according to the received downlink channel quality.
