Description

Resource allocation methods, devices and equipment

This application claims priority to the Chinese patent application filed with the China Patent Office on April 12, 2022, with application number 202210380989.8 and the application name "Resource Allocation Method, Device and Equipment", the entire content of which is incorporated into this application by reference. .

Technical field

The embodiments of the present application relate to the field of communication technology, and in particular, to a resource allocation method, apparatus and equipment.

Background technique

In network communication systems, information can be transmitted between different network devices through working bandwidth. If the working bandwidth is the downlink bandwidth, it can be used by the network device to send wireless signals to the terminal device; if the working bandwidth is the uplink bandwidth, it can be used by the terminal device to send wireless signals to the network device.

In the 5G communication system, in order to meet the demand for ultra-low latency, sub-band full-duplex technology can be introduced, that is, the operating bandwidth can be subdivided into multiple sub-bands according to the frequency domain, and the uplink and downlink ratios of the sub-bands can be flexibly configured. However, in a subband full-duplex scenario, uplink subbands and downlink subbands will appear simultaneously in the working bandwidth. The existing frequency domain resource configuration method is sequential mapping from low to high, and the configuration cycle is long, resulting in Wireless signals may be mapped to unavailable subbands, resulting in poor resource allocation reliability.

Figure 1 is a schematic diagram of an application scenario provided by an embodiment of the present application. Please refer to Figure 1 , including a network device and multiple terminal devices. For example, the network device may be a base station, and the terminal devices may include terminal device 1, terminal device 2, ..., terminal device n.

The network device can obtain the configuration information of the wireless signal and send the configuration information to the terminal device. After receiving the configuration information, the terminal device can determine the frequency domain resources to be used by the wireless signal based on the configuration information. Network devices and terminal devices can communicate with each other on designated frequency domain resources, that is, send or receive wireless signals. For example, the network device can communicate with the terminal device 1 on the frequency domain resource 1, communicate with the terminal device 2 on the frequency domain resource 2, ..., communicate with the terminal device n on the frequency domain resource n.

In the 5G communication system, in order to meet the demand for ultra-low latency, sub-band full-duplex technology can be introduced, that is, the operating bandwidth can be subdivided into multiple sub-bands according to the frequency domain, and the uplink and downlink of the sub-band can be flexibly configured. Proportion. However, in a subband full-duplex scenario, uplink subbands and downlink subbands will appear simultaneously in the working bandwidth. The existing frequency domain resource configuration method is sequential mapping from low to high, and the configuration cycle is long, resulting in Wireless signals may be mapped to unavailable subbands, so the reliability of resource allocation is poor.

In this embodiment of the present application, the network device can obtain the configuration information of the wireless signal and send the configuration information to the terminal device. After receiving the configuration information of the wireless signal sent by the network device, the terminal device can determine the frequency domain resources to be used by the wireless signal based on the physical resource blocks indicated by the configuration information. Network equipment and terminal equipment can communicate on designated frequency domain resources, avoiding the mapping of wireless signals to unavailable frequency domain resources, thereby improving the reliability of resource configuration.

Below, the technical solution shown in this application will be described in detail through specific embodiments. It should be noted that the following embodiments can exist alone or can be combined with each other. The same or similar content will not be repeatedly described in different embodiments.

Figure 2 is a schematic flowchart of a resource configuration method provided by an embodiment of the present application. See Figure 2, the method can include:

S201. The network device obtains the configuration information of the wireless signal.

The network device can obtain the configuration information of the wireless signal through the 5G network, and the configuration information can be used to indicate the location of at least one physical resource block (PRB). PRB refers to the resources of 12 consecutive carriers in the frequency domain. The location of the PRB can be indicated by a logo.

Next, the PRB will be described with reference to Figure 3.

Figure 3 is a schematic diagram of physical resource blocks provided by an embodiment of the present application. See Figure 3, the operating bandwidth can be divided into multiple PRBs based on frequency. Among them, a PRB consists of 12 subcarriers in the frequency domain, with a bandwidth of 180kHz.

Configuration information can be expressed in the following two ways:

Method 1: Configuration information can be represented by bitmap.

The bitmap may include multiple bits, each bit being used to indicate the identity of the corresponding PRB.

Next, the bitmap will be described with reference to FIG. 4 .

Figure 4 is a schematic diagram of a bitmap provided by an embodiment of the present application. Please refer to Figure 4. There can be 13 PRBs corresponding to the bitmap, and each PRB can have a corresponding identifier, which are 0, 1, 2,..., 12 respectively. Among them, two consecutive PRBs can be combined into a group of PRBs. For example, PRB-0 and PRB-1 can form the first group of PRBs, PRB-2 and PRB-3 can form the second group of PRBs, ..., PRB-11 and PRB-11 can form the 6th group of PRBs, and PRB-12 is the 7th group of PRBs.

As shown in Figure 4, the bitmap may be "1011000", where each bit is used to indicate a group of PRBs. For example, the first bit in the bitmap is 1, which can be used to indicate the group of PRBs PRB-0 and PRB-1, indicating that PRB-0 and PRB-1 are to be used; the second bit in the bitmap is 0, and used For indicating the group of PRBs PRB-2 and PRB-3, it means that PRB-2 and PRB-3 are not occupied. The first bit in the bitmap is the highest bit, corresponding to the lowest position in the frequency domain, and can be mapped in sequence.

Method 2: Configuration information can be represented by virtual resource block (VRB).

The configuration information may include the identity of at least one VRB, and the VRB identity is used to determine the identity of the corresponding PRB.

The ways in which VRB is mapped to PRB can include: centralized and distributed. Next, the mapping relationship between VRB and PRB will be described with reference to Figures 5A and 5B.

Figure 5A is a schematic diagram of centralized mapping provided by an embodiment of the present application. Please refer to Figure 5A, which includes multiple VRBs and multiple PRBs, and each VRB and PRB has a corresponding identification. For example, if there are 13 VRBs, the corresponding identifiers can be 0, 1, 2, ..., 12 respectively; if there are 13 PRBs, the corresponding identifiers can be 0, 1, 2, ..., 12 respectively. In the centralized mapping method, VRB and PRB correspond one to one, that is, one VRB can determine a corresponding PRB. As shown in Figure 5A, VRB-3, VRB-4, and VRB-5 are three consecutive VRBs, and the corresponding three consecutive PRBs can be determined as PRB-3, PRB-4, and PRB-5 respectively.

Figure 5B is a schematic diagram of distributed mapping provided by an embodiment of the present application. Please refer to Figure 5B, which includes multiple VRBs and multiple PRBs, and each VRB and PRB has a corresponding identification. For example, if there are 13 VRBs, the corresponding identifiers can be 0, 1, 2, ..., 12 respectively; if there are 13 PRBs, the corresponding identifiers can be 0, 1, 2, ..., 12 respectively.

In the distributed mapping method, VRB and PRB are not in one-to-one correspondence, and continuous VRB can be mapped to discontinuous PRB. As shown in Figure 5B, VRB-3, VRB-4, and VRB-5 are continuous continuous VRBs. Among them, VRB-3 can be used to determine PRB-2, VRB-4 can be used to determine PRB-6, and VRB-5 can be used to determine PRB-10. PRB-2, PRB-6, and PRB-10 are discontinuous. PRB.

S202. The network device sends configuration information to the terminal device.

Network devices can send configuration information to terminal devices through the 5G network. For example, wireless The configuration information of the number may include VRB-3, VRB-4, and VRB-5, where VRB-3 can be used to determine PRB-2, VRB-4 can be used to determine PRB-6, and VRB-5 can be used to determine PRB. -10.

S203. The terminal device determines the frequency domain resources to be used by the wireless signal according to the configuration information.

For example, if the configuration information includes VRB-3, VRB-4, and VRB-5, and VRB-3 can be used to determine PRB-2, VRB-4 can be used to determine PRB-6, and VRB-5 can be used to determine PRB- 10, then the terminal device can determine that the frequency domain resources to be used by the wireless signal are PRB-2, PRB-6 and PRB-10.

In this embodiment of the present application, the network device can obtain the configuration information of the wireless signal and can send the configuration information to the terminal device. The terminal device can determine the frequency domain resources to be used by the wireless signal according to the physical resource blocks indicated by the configuration information. Network equipment and terminal equipment can communicate on designated frequency domain resources, avoiding the mapping of wireless signals to unavailable frequency domain resources, thereby improving the reliability of resource configuration.

The resource configuration method may include a resource configuration method for physical uplink and downlink shared channels.

Among them, the physical channel is the actual bearer of wireless signals in the wireless network. Physical channels can include physical downlink shared channel (PDSCH) and physical uplink shared channel (physical uplink shared channel, PUSCH). Among them, PDSCH can be used by the network device to send wireless signals to the terminal device; PUSCH can be used by the terminal device to send wireless signals to the network device.

Next, on the basis of the embodiment shown in Figure 2 and in conjunction with Figure 6, the resource configuration method of the physical downlink shared channel will be described in further detail. Figure 6 is a schematic flowchart of a resource configuration method for a physical downlink shared channel provided by an embodiment of the present application.

PRB-8 and PRB-9 are determined as frequency domain resources, and these frequency domain resources can be used by the terminal equipment to receive PDSCH.

S604. The network device sends PDSCH to the terminal device on frequency domain resources.

For example, if PRB-0, PRB-1, PRB-2, PRB-3, PRB-8, and PRB-9 are determined to be frequency domain resources, the network device can send PDSCH to the terminal device on these 6 designated PRBs. So that the terminal equipment receives PDSCH on the 6 designated PRBs.

The operating bandwidth can be subdivided into multiple subbands according to the frequency domain. The frequency domain mapping subband can be the downlink subband with the lowest frequency in the operating bandwidth, or it can be the downlink subband indicated in the configuration information. Each subband may include multiple PRBs. The terminal device may determine the starting PRB of the frequency domain mapping subband as the second starting PRB.

Next, the subbands will be described with reference to FIG. 9 .

Figure 9 is a schematic diagram of a subband provided by an embodiment of the present application. Referring to Figure 9, the operating bandwidth can be divided into multiple PRBs according to the frequency domain. Further, the working bandwidth can be divided into multiple sub-bands, and each sub-band can include multiple PRBs. For example, subband 1 may include 6 PRBs, namely PRB-11, PRB-12, PRB-13, PRB-14, PRB-15, and PRB-16, then the starting PRB of subband 1 is PRB-11; Subband 2 can include 7 PRBs, namely PRB-65, PRB-66, PRB-67, PRB-68, PRB-69, PRB-70, and PRB-71. The starting PRB of subband 2 is PRB- 65. If the frequency domain mapping subband is subband 1 and the starting PRB of subband 1 is PRB-11, the terminal device may determine PRB-11 as the second starting PRB.

S804: The terminal device determines the mapping starting PRB based on the first starting PRB and the second starting PRB.

In an optional embodiment, the mapping starting PRB is determined based on the first starting PRB and the second starting PRB, including the following two situations:

Next, the position of the mapping start PRB will be described with reference to Figures 10A and 10B.

Case 1: If the identifier of the first starting PRB is greater than or equal to the identifier of the second starting PRB, the first starting PRB is determined as the mapping starting PRB.

Figure 10A is a schematic diagram of the location of a mapping start PRB provided by an embodiment of the present application. Referring to Figure 10A, if the configuration information indicates that the frequency domain mapping subband is subband 1 and indicates that there are 10 PRBs, the first starting PRB is PRB-2. Then the terminal device can determine that subband 1 includes 15 PRBs, and the starting PRB of subband 1 is PRB-0, then the terminal device can determine PRB-0 as the second starting PRB. Since the identity of the first starting PRB is greater than the identity of the second starting PRB, the terminal device can determine the first starting PRB, that is, PRB-2, as the mapping starting PRB.

Case 2: If the identifier of the first starting PRB is smaller than the identifier of the second starting PRB, the second starting PRB is determined as the mapping starting PRB.

Figure 10B is a schematic diagram of the location of another mapping start PRB provided by an embodiment of the present application.

Please refer to Figure 10B. If the configuration information indicates that the frequency domain mapping subband is subband 2, and the indication is that there are 10 PRBs, where the first starting PRB is PRB-0. Then the terminal device can determine that subband 2 includes 8 PRBs, and the starting PRB of subband 2 is PRB-3, then the terminal device can determine PRB-3 as the second starting PRB. Since the identifier of the first starting PRB is smaller than the identifier of the second starting PRB, the terminal device may determine the second starting PRB, that is, PRB-3, as the mapping starting PRB.

S805. The terminal device determines the remaining PRBs.

The terminal device can determine the remaining PRBs based on the mapping starting PRB and the ending PRB of the frequency domain mapping subband, which can include the following two situations:

Case 1: If the frequency domain mapping subband is a certain downlink subband, the remaining PRBs are determined based on the mapping starting PRB and the ending PRB of the downlink subband.

As shown in Figure 10A, if the frequency domain mapping subband is subband 1, and the mapping starting PRB is PRB-2; if the ending PRB of subband 1 is PRB-14, the terminal device can use PRB-2 in subband 1 Up to PRB-14 is determined as the remaining PRB.

Case 2: If the frequency domain mapping subband is multiple downlink subbands, the remaining PRBs are determined based on the mapping start PRB and the termination PRB of the multiple downlink subbands.

For example, if the frequency domain mapping subband includes subband 1 and subband 3, and the frequency domain position of subband 3 is lower than the frequency domain position of subband 1, subband 1 and subband 3 are both subbands for transmitting downlink signals. If the starting PRB to the ending PRB corresponding to subband 3 are PRB-0 to PRB-8, the starting PRB to the ending PRB corresponding to subband 1 are PRB-20 to PRB-31. Then the terminal device can determine the mapping starting PRB according to the starting PRB corresponding to subband 3. If it is determined that the mapping starting PRB is PRB-1, the terminal device can map PRB-1 to PRB-8 and subband 3 in subband 3. PRB-20 to PRB-31 of 1 are determined as remaining PRBs.

S806: The terminal device determines frequency domain resources according to the mapping starting PRB, remaining PRBs and the first quantity.

The terminal device may determine the number of PRBs used for transmitting downlink signals among the remaining PRBs as the second number, and further determine the frequency domain resources according to the mapping starting PRB, the second number, and the first number. Specifically, it can include the following four situations:

If the frequency domain mapping subband is a certain downlink subband, then the remaining PRBs are all PRBs in the downlink subband, which can include case 1 and case 2, where,

Case 1: If the second quantity is greater than or equal to the first quantity, frequency domain resources can be determined in the remaining PRBs according to the mapping starting PRB and the first quantity.

As shown in Figure 10A, if the frequency domain mapping subband indicated in the configuration information is subband 1, and there are 10 PRBs indicated, the first number is 10. If the terminal equipment determines that the remaining PRBs of subband 1 are PRB-2 to PRB-14, and PRB-2 to PRB-14 are all used to transmit downlink signals, then the corresponding second number is 13. Since the second number is greater than the first number, the terminal device may determine 10 PRBs from PRB-2 to PRB-11 in PRB-2 to PRB-14 of subband 1 as frequency domain resources.

Case 2: If the second number is less than the first number, the remaining PRBs can be determined as frequency domain resources according to the mapping starting PRB and the second number.

As shown in Figure 10B, if the frequency domain mapping subband indicated in the configuration information is subband 2 and there are 10 PRBs indicated, the first number is 10. If the terminal equipment determines that the remaining PRBs of subband 2 are PRB-3 to PRB-10, and PRB-3 to PRB-10 are all used to transmit downlink signals, then the corresponding second number is 8. Since the second number is smaller than the first number, the terminal device can determine PRB-3 to PRB-10 in subband 2, a total of 8 PRBs, as frequency domain resources.

If the frequency domain mapping subband is multiple downlink subbands, the remaining PRBs are PRBs in multiple downlink subbands, including case 3 and case 4. Next, the determination of frequency domain resources in multiple subbands will be described with reference to Figures 11A and 11B.

Case 3: If the second number of PRBs used to transmit downlink signals in multiple downlink subbands is greater than or equal to the first number, frequency domain resources are determined in the remaining PRBs according to the mapping starting PRB and the first number.

Figure 11A is a schematic diagram 1 of determining frequency domain resources provided by an embodiment of the present application. Referring to Figure 11A, if the working bandwidth includes subband 1, subband 2 and subband 3, subband 1 and subband 3 are downlink subbands, and subband 2 is the uplink subband. If the configuration information indicates that the frequency domain mapping subbands are subband 3 and subband 1, and include 10 PRBs. Then the terminal equipment can determine that the remaining PRBs in subband 3 are PRB-1 to PRB-12, where PRB-1 to PRB-12 are used to transmit downlink signals, a total of 12 PRBs; determine that the PRB in subband 1 is PRB- 20 to PRB-30, of which PRB-20 to PRB-30 are used to transmit downlink signals, a total of 11 PRBs. Among them, the frequency domain position of subband 3 is lower than the frequency domain position of subband 1. Although the configuration information indicates subband 1 and subband 3, the number of PRBs transmitting downlink signals in subband 3 is 12, which is larger than the 10 PRBs indicated in the configuration information, and the frequency domain position of subband 3 is lower than that of the subband. If the frequency domain position is 1, the terminal device can determine PRB-1 to PRB-10 in subband 3, a total of 10 remaining PRBs, as frequency domain resources.

Case 4: If the second number of PRBs used to transmit downlink signals in multiple downlink subbands is less than The first quantity determines frequency domain resources in PRBs of multiple downlink subbands according to the mapping starting PRB and the first quantity.

Figure 11B is a second schematic diagram of determining frequency domain resources provided by an embodiment of the present application. Referring to Figure 11B, if the working bandwidth includes subband 1, subband 2 and subband 3, subband 1 and subband 3 are downlink subbands, and subband 2 is the uplink subband. If the configuration information indicates that the frequency domain mapping subbands are subband 1 and subband 3, and include 20 PRBs; if the terminal device determines that there are 9 PRBs in subband 3 for transmitting downlink signals, and subband 1 is used for transmission There are 10 PRBs for the downlink signal, among which the frequency domain position of subband 3 is lower than the frequency domain position of subband 1. If the terminal equipment determines that the remaining PRBs in subband 3 are PRB-1 to PRB-9, among which PRB-1 to PRB-9 are used to transmit downlink signals, a total of 9 PRBs; determine that the PRB in subband 1 is PRB-20 to PRB-29, of which PRB-20 to PRB-29 are used to transmit downlink signals, a total of 10 PRBs, then the terminal equipment can use PRB-1 to PRB-9 in sub-band 3, PRB- 20 to PRB-29, determined as frequency domain resources. Since subband 2 in the working bandwidth is used to transmit uplink signals, the PRB in subband 2 is unavailable, and subband 2 can be avoided during the mapping process.

The terminal device may determine the remaining PRBs according to the mapping starting PRB and the ending PRB of the frequency domain mapping subband, and determine the second number of PRBs used to transmit downlink signals among the remaining PRBs. Further, the terminal device may determine the remaining PRBs according to the mapping starting PRB, the third The second quantity and the first quantity are used to determine the remaining PRBs or the frequency domain resources in the remaining PRBs, and receive the downlink channel state information reference signal on the frequency domain resources.
