Description

Resource indication method, device and system Technical field

This application relates to the communication field, and more specifically, to a method and device for resource indication in the communication field.

Background technique

Due to the development of communication standards and industry demands, there is a discontinuity of available spectrum in the division of spectrum resources. In some scenarios, the discrete frequency points have a small bandwidth, which can only provide lower-rate access and 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, a plurality of discontinuous narrowband spectrums on the broadband spectrum are aggregated and used. Through discrete narrowband communication technology, it is possible to achieve broadbandization of discrete narrowband resources, increase terminal bandwidth capabilities, and meet high-speed data service requirements.

When the discrete narrowband cellular communication system is scheduled, the more narrowband spectrum is aggregated, the higher the transmission rate will be. In the existing discrete carrier aggregation air interface protocol, the physical carriers are mapped one by one to the logical carrier index in a low-to-high manner. During resource allocation, scheduling is performed based on the logical carrier index. When the access network device performs resource scheduling, the control information indicates the starting position and the number of logical carriers for data transmission or reception. Therefore, when a certain carrier has large interference, the access network equipment does not want to use the carrier to send or receive data. The logical carrier resources are continuously allocated, and the unscheduled interference of the carrier causes the available logical carriers to be discontinuous, which limits the number of continuously scheduled carriers, thereby reducing the data transmission rate.

Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Before describing the technical solutions of the embodiments of the present application, first, the application scenarios of the embodiments of the present application will be described with reference to the drawings.

First of all, in order to facilitate the understanding of this application, the basic concepts involved in this application are introduced below.

Discrete Spectrum Aggregation: Due to the development of communication standards and industry requirements, spectrum resources are divided. Among them, the bandwidth of each frequency point of the discrete spectrum is relatively small and can only provide lower rate access. If the terminal uses the discrete spectrum to communicate with access network equipment (such as a base station), it cannot meet the communication requirements of the terminal for high-speed data services. In order to meet the communication requirements of the terminal's high-speed data services, carrier aggregation (CA) technology (or discrete narrowband communication technology) is proposed, for example, two or more discrete component carriers (CC) are aggregated and allocated together For the terminal, to support the terminal to transmit data services on a larger transmission bandwidth to meet the communication requirements of high-speed data services.

Physical carrier index (absolute physical carrier index): the index of the physical frequency point itself. One physical carrier index corresponds to one physical carrier (or one frequency domain physical resource).

Logical carrier index: carrier number, logical carrier index and physical carrier index (or physical carrier or frequency domain physical resource) have a one-to-one correspondence (or one-to-one mapping) relationship.

Physical carrier index: A frequency domain physical resource (or a frequency domain physical resource unit) may be a physical resource block (PRB) in the frequency domain. For example, in an LTE system, a PRB occupies 12 subcarriers. A frequency domain physical resource can also be a carrier. For example, a frequency domain physical resource is a carrier of a narrowband system. In the power private network system, the bandwidth of a carrier is 25kHz. In other words, one frequency domain physical resource may be one of the carriers available in the narrowband system.

Carrier-based frequency hopping: Frequency hopping based on a single carrier. The basic unit of frequency hopping is based on the carrier.

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 based on a group of carriers.

Time unit: In this application, the length of a time unit can be set arbitrarily, and there is no restriction here.

For example, 1 time unit may include one or more subframes.

Alternatively, 1 time unit may include one or more time slots.

Alternatively, 1 time unit may include one or more mini-slots.

Alternatively, 1 time unit may include one or more symbols.

Alternatively, one time unit may include one or more transmission time intervals (Transmission Time Interval, TTI).

Alternatively, one time unit may include one or more short transmission time intervals (short Transmission Time Interval, sTTI).

Alternatively, one time unit may correspond to one time mode, for example, the first time mode is a transmission time interval of 2 symbols or 3 symbols, and the second mode is a transmission time interval of 7 symbols.

Among them, the mini time slot includes one or more symbols, and the mini time slot is less than or equal to the time slot. The time slot here can be a mini time slot in a system with a subcarrier spacing of 60kHz or a mini time slot in a system with a subcarrier spacing of 15kHz. The time slot is not limited in the embodiment of the present invention.

Wherein, the time slot includes one or more symbols. The time slot here can be a time slot in a system with a 60kHz subcarrier spacing, or a time slot in a system with a 15kHz subcarrier spacing, which is not limited in the embodiment of the present invention.

Among them, TTI is a commonly used parameter in current communication systems (for example, Long Term Evolution (LTE) system), and refers to a scheduling unit for scheduling data transmission in a wireless link. In LTE, it is generally considered that 1TTI=1ms. That is, one TTI is the size of one subframe (subframe) or two slots (slot), which is the basic unit of time governed by radio resource management (scheduling, etc.). In the electric power wireless private network system, the domestic 230M frequency band 25kHz carrier interval is currently supported, and one TTI is one frame (there are two frame structures, 10ms and 20ms).

Channel quality: Channel quality is a way to evaluate the attenuation of the signal by the channels of the two communication parties. Channel quality is also a way for the receiver to evaluate the "good" or "bad" of the received signal. Channel quality can be expressed as reference signal received power RSRP, reference signal received quality RSRQ, channel quality information CQI measured by terminal equipment, or received interference power (Received, RIP Interference Power) value of physical carrier, signal to noise ratio, signal and Interference plus noise ratio, etc.

The frequency domain physical resources are interleaved and arranged in the frequency domain: two sets of frequency domain physical resources are interleaved in the frequency domain. However, the frequency domain physical resources of the two sets do not overlap. For example, the frequency points (frequency of the carrier) of the physical resources of the first set are 1, 3, and 7 (unit: M Hz); the frequency points of the physical resources of the second set are 2, 10, and 11. In other words, at least one frequency point of at least one of the two sets 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.

The xth frequency domain resource logical index, the xth frequency domain physical resource (x is a positive integer): the xth frequency domain resource logical index represents one or more frequency domain resource logical indexes; the xth 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 indexes.

Terminal device: The terminal device can be a terminal device or a chip in a terminal device device. Hereinafter, the embodiment is described as an example where the terminal device is a terminal device.

The channel through which the access network device sends data to the terminal device is the downlink channel. The channel through which the terminal device sends data to the access network device is the uplink channel. Moreover, the terminal device 10a and the terminal device 10b can also communicate via a wireless link.

Fig. 2 is a schematic diagram of an effective carrier provided by an embodiment of the application. In the first row in Figure 2, physical carrier indexes 1-20 are given, and each physical carrier index corresponds to a frequency domain physical resource. One frequency domain physical resource can be one carrier. In this application, one frequency domain physical resource is used as one carrier as an example for description. The bandwidth of each carrier is the same, and the physical carrier index 1-20 corresponds to the continuous physical carrier. For example, the bandwidth of each carrier is 1MHz, and the starting frequency of physical carrier index 1 is 2G Hz. The frequency domain resource corresponding to physical carrier index 1 is 2G to 2G+1MHz; the frequency domain resource corresponding to physical carrier index 2 is 2G+1MHz to 2G+2MHz; and so on, the frequency domain resource corresponding to physical carrier index 20 is 2G+ 19MHz to 2G+20MHz.

When deploying the network, the operator or the enterprise network determines that the physical carrier index 6, 7, 11, 12, 15, 16 is not available for the access network equipment. One reason why the physical carrier index is unavailable is that the physical carrier corresponding to the physical carrier index is not allocated to the communication network to which the access network device belongs. For example, the communication network is an enterprise network, and the physical carrier corresponding to the physical carrier index 6, 7, 11, 12, 15, 16 is not allocated to the enterprise. In the second row of FIG. 2, a valid carrier of 1 indicates that the physical carrier index is available, and a valid carrier of 0 indicates that the physical carrier index is not available. The third row of Figure 2 shows the correspondence between the logical carrier index or the physical channel index after removing the unavailable carrier of the access network device. For example, logical carrier index 6 corresponds to physical carrier index 8.

When the physical carrier index is 3, 8, 10, 18, the interference on the corresponding physical carrier is large (equivalent to poor channel quality or poor signal reception quality). The access network device does not want to communicate with the terminal device on the physical carrier corresponding to the physical carrier index of 3, 8, 10, and 18. Moreover, when the access network device performs resource scheduling, it is allocated a continuous logical carrier index. In this case, in order to avoid physical carriers corresponding to physical carrier indexes 3, 8, 10, and 18 during scheduling, for logical carrier indexes 1-8, 3 or more carriers cannot be allocated at a time.

In order to solve the above-mentioned problems, Fig. 3 shows a flowchart of the access network device receiving data from the terminal device. In Fig. 3, one frequency domain physical resource unit is taken as an example for one carrier. In this case, the frequency domain resource logical index is the logical carrier index.

In step 301, the access network device sends a one-to-one correspondence between the first frequency domain resource logical index and the first frequency domain physical resource to the terminal device. Different frequency domain resource logical indexes correspond to different frequency domain physical resources. Referring to FIG. 2, the first frequency domain physical resource is the corresponding carrier of the physical carrier index 1-5, 8-11, 14, 17-19.

The first frequency domain resource logical index includes a first set and a second set. The logical indexes of frequency domain resources included in the first set are continuous indexes, and the logical indexes of frequency domain resources included in the second set are continuous indexes. That is, the logical indexes of frequency domain resources included in the first set and the second set are all continuous indexes. The frequency domain physical resources corresponding to the frequency domain resource logical index in the first set and the frequency domain physical resources corresponding to the frequency domain resource logical index in the second set are interleaved and arranged in the frequency domain. Any logical index of frequency domain resources included in the first set is different from any logical index of frequency domain resources included in the second set.

For example, the channel quality of the frequency domain physical resource corresponding to any frequency domain resource logical index included in the first set is lower than the threshold; the channel quality of the frequency domain physical resource corresponding to any frequency domain resource logical index included in the second set Not lower than the threshold. Figure 4 shows the corresponding relationship between the frequency domain resource logical index and the frequency domain physical resource index. Since the frequency domain physical resource index and the frequency domain physical resource have a one-to-one correspondence, FIG. 4 also shows the corresponding relationship between the frequency domain resource logical index and the frequency domain physical resource. Figure 4 is based on Figure 2. In Figure 4, only valid carriers are drawn. The first row of Fig. 4 is similar to Fig. 2 and will not be repeated here. The second row of Figure 4 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. Fig. 5 shows an example in which the access network device determines the channel quality of the frequency domain physical resources before step 301.

In step 501, the access network device receives a reference signal from the terminal device. The reference signal may be a sounding reference signal (SRS).

In step 502, the access network device measures the signal reception quality according to the reference signal. For example, among the effective physical carriers, the physical carrier index of the physical carrier index is 1, 2, 4, 5, 9, 11, 14 has a high channel quality evaluation, and the physical carrier index is 3, 8, 10, 18. The channel quality is evaluated as low. Taking the signal reception quality as RIP as an example, it is equivalent to physical carriers with physical carrier indexes of 3, 8, 10, and 18 that have greater interference and are physical carriers that the access network device does not want to schedule.

As shown in Figure 4, the logical carrier index corresponding to the physical carrier index of 3, 8, 10, 18 is a continuous index (belonging to the first set); the physical carrier index is 1, 2, 4, 5, 9, 11, 14 The corresponding logical carrier index is a continuous index (in the second set). The first frequency domain resource logical index is the logical carrier index 1-13 in FIG. 4.

The access network equipment can have the following methods for the correspondence between the physical carrier index and the logical carrier index: Method 1: The access network equipment assigns the physical carrier to the first set or the second set according to the reception quality of the physical carrier signal. The physical carrier index and the logical carrier index in the first set or the second set correspond randomly.

For example, the physical carrier whose RIP measured by the access network device is higher than 10DB is the second set, for example, the physical carrier index 3, 8, 10, 18 in Figure 4; the physical carrier whose RIP measured by the access network device is less than or equal to 10DB is The first collection. As shown in Figure 4. Through this mapping method, the access network device can schedule a physical carrier with a higher channel quality for data transmission or reception as much as possible, thereby improving the reliability of data communication.

Method 2: The access network equipment is sorted according to the physical carrier signal reception quality from high to low. That is, the first frequency domain resource logical index corresponds to the frequency domain physical resources with channel quality from high to low in the first frequency domain physical resources in a descending order.

For example, the RIP measured by the access network equipment is sorted from low to high, and its corresponding logical carrier index is numbered from low to high. As shown in FIG. 4, the physical carrier with physical carrier index 1 has the lowest RIP value, and the physical carrier with physical carrier index 18 has the highest RIP value.

Among them, the last four 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 four physical carriers to communicate with the terminal device.

Method 3: The access network equipment is sorted according to the physical carrier signal reception quality from low to high. Mode 3 can refer to Mode 2, which will not be repeated here. Method 2 or 3 mapping method, because 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 increasing the data rate of the entire system.

In the above mapping method, when the access network device performs resource scheduling through continuous logical carrier indexing, more resources can be allocated, thereby increasing the terminal transmission rate, reducing the terminal transmission delay, and improving the utilization of spectrum resources.

In a possible design, the access network device and the terminal device communicate through frequency hopping. In other words, the access network device receives data on the second frequency domain physical resource in a frequency hopping manner. 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 frequency hopping unit of single carrier frequency hopping is a frequency domain physical resource. For example, a logical carrier with a logical carrier index of 1 is mapped to a physical carrier with a physical carrier index of 1 in the first time unit; at a second time unit, the logical carrier is mapped to a physical carrier with a physical carrier index of 13.

For group frequency hopping, a group of logical carriers is mapped to different physical carriers at different time units. A frequency domain frequency hopping unit of group frequency hopping is a plurality of frequency domain physical resources. For example, a group of logical carriers with logical carrier indexes 1, 2 are mapped to physical carriers with physical carrier indexes 1, 2 in the first time unit, respectively. In the second time unit, logical carriers with logical carrier indexes of 1, 2 are mapped to physical carriers with physical carrier indexes of 13, 14 respectively. Among them, the relevant parameters of a group of carriers in the group frequency hopping can be predefined according to product requirements. The access network equipment can also send relevant parameters to the terminal equipment through signaling. For example, the product terminal RF (Radio Frequency) radio frequency capability bandwidth is too small, a group of carriers in the group frequency hopping can be defined as a group of continuous physical carriers, and the number of carriers in a group is 4.

When in a time unit, a cell exists at the same time when single carrier frequency hopping and group frequency hopping. The effective carriers in the system first form the resources of the group frequency hopping carrier. The remaining carriers that are not group frequency hopping carriers are used as single-carrier frequency hopping carrier resources. Figure 6 shows a schematic diagram of group frequency hopping and single carrier frequency hopping. As shown in Figure 6, a group of carriers in group frequency hopping is 4 consecutive physical carriers. Since the physical carrier indexes 6, 7, 12, 13, 15, 16, and 20 in Figure 6 are invalid carriers, in the physical carrier indexes 1-20, only 1-4, 8-11 can form two frequency hopping groups. Physical carrier index 1-4 is a frequency hopping group, and 8-11 is another frequency hopping group. The remaining physical carrier indexes 5, 14, 17-19 are used for single carrier frequency hopping. The group hopping size in Figure 6 is the number of consecutive physical carriers included in a hopping group. In Figure 6, effective carriers are divided into group hopping carrier resources and single carrier frequency hopping carrier resources. The group hopping carrier and the non-group hopping carrier corresponding to the logical carrier index in FIG. 6 are interleaved (or coexist with intervals). During resource scheduling of access network equipment, because the resource allocation indication is continuous resource allocation (logical carrier index is continuous), and single-carrier frequency hopping carriers and group frequency hopping carriers cannot be mixed, the number of continuously allocated resources (the number of carriers) will be affected. limit. For example, in FIG. 6, it is assumed that the access network device allocates single-carrier frequency hopping resources to the terminal device A. Logical carrier index 5 (physical carrier index 5) cannot be allocated together with logical carrier index 10-13. In another example, referring to FIG. 6, the access network device allocates the group frequency hopping carrier resource to the terminal device B. In the same way, because the first group of frequency hopping carrier resources (logical carrier index 1-4) and the second group of frequency hopping carrier resources (logical carrier index 6-9) separate the frequency hopping resources of a single carrier (logical carrier index 5) ), the access network equipment cannot allocate these two groups at one time for terminal equipment B for data transmission. This leads to limited carrier data that can be scheduled at one time, and carrier utilization decreases.

Fig. 7 is based on Fig. 6, a schematic diagram of mapping the logical carrier index to the physical carrier in the case where both group frequency hopping and single carrier frequency hopping exist in Fig. 7. Figure 7 only shows the effective carrier. The first row and the second row of FIG. 7 are similar to those of FIG. 6 and will not be repeated. The frequency domain physical resource corresponding to any one frequency domain resource logical index included in the second set belongs to the frequency domain physical resource of single carrier frequency hopping; the frequency domain physical resource corresponding to any one frequency domain resource logical index included in the first set belongs to group hopping Frequency domain physical resources. In Figure 7, the frequency domain resource logical index in the first set is the logical carrier index of the group frequency hopping carrier, and the index is 1-8; the frequency domain resource logical index in the second set is the logical carrier index of single carrier frequency hopping , The index is 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 increasing the terminal transmission rate, reducing the terminal transmission delay, and improving the utilization of spectrum resources.

In step 302, the access network device sends instruction information to the terminal device. The indication information indicates the second frequency domain resource logical index, 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 index is a continuous index, and the second frequency domain resource logical index has a one-to-one correspondence with the second frequency domain physical resource.

The indication information indicates the logical index of the frequency domain resource 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 index of the data to be received is a continuous index. For example, the indication information is carried in scheduling signaling. The frequency domain physical resource of the data to be received is a discontinuous physical resource.

Taking FIG. 4 as an example, the indication information indicates that the starting logical carrier index is 2, and the number of logical carrier indexes is 5. The second frequency domain resource logical index is logical carrier index 2-6. After the terminal device receives it, the terminal device sends the data on the physical carrier corresponding to the logical carrier index 2-6 (the physical carrier index is 2, 4, 5, 9, 11).

Taking the group frequency hopping in FIG. 7 as an example, the indication information indicates the starting carrier logical index 1, and the length is 4. The logical index of the second frequency domain resource is that the logical carrier index is 1-4, and the corresponding physical carrier index is 1-4. After the terminal device (for example, terminal device B) receives it, the terminal device sends data on the physical carrier of the physical carrier index 1-4.

The terminal device receives the instruction information at the kth time unit, and the terminal device can send data at the k+pth time unit, and p is a positive integer.

In step 303, the access network device receives data from the terminal device.

The access network device receives data from the terminal device on receiving data on the second frequency domain physical resource. Taking FIG. 4 as an example, referring to step 302, the access network device receives data from the terminal device on the physical carrier whose physical carrier index is 2, 4, 5, 9, and 11. Taking FIG. 7 as an example, referring to step 302, the access network device receives data from a terminal device (for example, terminal device B) on a physical carrier with a physical carrier index of 1-4.

Figure 8 shows the flow chart of the access network device sending data to the terminal device. The main difference between Fig. 8 and Fig. 3 is that in Fig. 3, it is uplink data transmission; in Fig. 8, it is downlink data transmission. The following description mainly focuses on the differences between FIG. 8 and FIG. 3.

Step 801, refer to step 301, which will not be repeated here.

Step 802: In 802, the logical index of the frequency domain resource indicated by the indication information sent by the access network device is used to notify the terminal device that it is used for receiving downlink data. The terminal device determines the physical resource for receiving the data according to the instruction information. For details, refer to step 302, and change the data sent by the terminal device in step 302 to the data received by the terminal device (equivalent to the difference between 803 and 303).

Step 803: The access network device sends data to the terminal device.

The terminal device receives data from the access network device on the frequency domain physical resource determined in step 802.

For logical resource index, physical resource index, single carrier frequency hopping, group frequency hopping, etc., refer to the description in FIG. 3.

Fig. 9 shows an example in which the access network device receives the downlink channel quality sent by the terminal device before step 801.

In step 901, the access network device sends a reference signal to the terminal device. The reference signal may be a channel state information (CSI) reference signal.

The terminal equipment measures the downlink channel quality according to the reference signal.

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. CQI is used to indicate the quality of the downlink channel. 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.
