Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource configuration method and device. Background Art

[0002] In a mobile communication system, before a terminal device accesses a cell in the system, it obtains the system information of the cell, and then determines how to configure the cell according to the system information so that the terminal device can work normally in the cell. The system information mainly includes basic system information and other system information, and the basic system information includes Master Information Block (MIB) and System Information Block 1 to System Information Block 9 (SIB1 to SIB9).

[0003] In the standard of the New Radio Access Technology (NR) (the Third Generation Partnership Project, 3GPP), the network equipment broadcasts a synchronization signal block (Synchronization Signal Block, SSB), and the SSB carries a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH). The terminal device obtains the configuration information of the physical downlink control channel (PDCCH) of MIB and SIB1 through the PBCH (for example, the time domain configuration information of PDCCH, etc.), wherein the MIB includes the configuration information of the control resource set 0 (Control Resource Set, Coreset0) (for example, the bandwidth size and frequency domain position of Coreset0, etc.).

[0004] Furthermore, before performing Radio Resource Control RRC Connection Setup / Resume / Establishment, the network device uses the bandwidth configured in the Coreset0 to send the SIB1 to the terminal device on the PDCCH, wherein the SIB1 contains resource configuration information for downlink data after the RRC connection is completed, and the bandwidth of the initial downlink (Downlink, DL) bandwidth part (Bandwidth Part, BWP) indicated by the resource configuration information is greater than the bandwidth configured in the Coreset0. When the terminal device determines that the cell is operating normally based on the acquired MIB and SIB1, the terminal device establishes an RRC connection with the network device to achieve data transmission.

[0005] However, the bandwidth of the DL BWP indicated by the resource configuration information contained in the SIB1 can only be used after the RRC connection is established. Therefore, before the RRC connection is established (including when the RRC connection is established), the network device cannot flexibly configure the resource indication information in the SIB1 according to the actual situation of the channel where the terminal device is located, and the network device still uses the bandwidth configured in the Coreset0 to send downlink messages to the terminal device. Since the bandwidth configured in the Coreset0 is small, the demodulation performance of the downlink message before the RRC connection is established is poor, and the terminal device cannot correctly decrypt the downlink message after receiving it. Summary of the invention

[0043] An embodiment of the present application provides a resource configuration method for improving the demodulation performance of downlink messages before the RRC connection is established.

[0044] Among them, the method and device described in this application are based on the same inventive concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0045] In the technical solution of the embodiment of the present application, the network device generates a system message, the system message includes resource indication information, the resource indication information is used to indicate the resources used by the target downlink message, the target downlink message is the downlink message of the terminal device before the completion of the radio resource control RRC connection; the network device sends the system message to the terminal device.

This method can not only improve the demodulation performance of the target downlink message, but also ensure that the terminal device can correctly decrypt the target downlink message after receiving it.

[0046] Some terms used in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

[0047] 1. Network equipment, for example, including access network (AN) equipment, such as base stations (e.g., access points), can refer to equipment in the access network that communicates with wireless terminal devices over the air interface through one or more cells, or, for example, a network device in a vehicle-to-everything (V2X) technology is a roadside unit (RSU). The base station can be used to convert received air frames to and from IP packets, acting as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The RSU can be a fixed infrastructure entity that supports V2X applications and can exchange messages with other entities that support V2X applications. The network equipment can also coordinate the attribute management of the air interface. For example, the network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (LTE) system or an advanced long term evolution (LTE-A), or may also include a next generation node B (next generation node B, gNB) in a fifth generation mobile communication technology (the 5th generation, 5G) new radio (new radio, NR) system (also referred to as an NR system) or may also include a centralized unit (CU) and a distributed unit (DU) in a cloud access network (CloudRAN) system, and the embodiments of the present application are not limited.

[0048] 2. Terminal equipment is a device that provides voice and / or data connectivity to users. Terminal equipment can also be called user equipment (UE), mobile station (MS), mobile terminal (MT), etc.

[0049] For example, the terminal device may be a handheld device or a vehicle-mounted device with a wireless connection function. At present, some examples of terminal devices include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0050] 3. In the description of this application, words such as "first", "second", and "third" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0051] The embodiments of the present application are described below with reference to the accompanying drawings.

[0052] Figure 1 A communication system to which a resource configuration method provided by the present application is applicable is shown. As shown in the figure, in the communication system, a network device (taking a base station 101 as an example) and a core network 102 are included. The interface between the base station 101 and the core network 102 is called an S1 interface, and the base station 101 communicates with the core network 102 through the S1 interface. The base station 101 can manage multiple cells (for example, cell A and cell B), and the terminal device 103 can access any one of the cells to access the network to achieve wireless communication.

[0053] In this communication system, before the terminal device 103 accesses a cell (taking cell A as an example), the base station 101 broadcasts a synchronization signal block SSB, and the SSB carries a primary synchronization signal PSS, a secondary synchronization signal SSS and a physical broadcast channel PBCH. The terminal device 103 can obtain the configuration information of the main system information block MIB and the physical downlink control channel PDCCH of the system message type SIB1 in the system message through the PBCH. The terminal device 103 obtains the configuration information of the control resource set Coreset0 according to the MIB, and detects the PDCCH in the Coreset0 to determine the physical downlink shared channel (PDSCH) used to carry the SIB1.

[0054] Further, the terminal device 103 receives the SIB1 on the PDSCH using the bandwidth size configured in the Coreset0. The SIB1 contains the information required for the terminal device 103 to access the cell A and the scheduling information of other SIBs, and the SIB1 also contains the resource configuration information required for data transmission when the terminal device 103 is in a connected state. The terminal device 103 determines how the cell A is configured based on the MIB and SIB1, so as to ensure normal operation in the cell A.

[0055] After determining that the terminal device 103 can work normally in cell A, the terminal device 103 initiates an RRC connection establishment request to the base station 101. During the RRC connection establishment process, the bandwidth configured in Coreset0 is used to transmit information between the terminal device 103 and the base station 101. After the RRC connection is established, the base station 101 sends downlink data to the terminal device 103 using the bandwidth indicated by the resource configuration information in SIB1.

[0056] In summary, before the RRC connection is established (including when the RRC connection is established), the base station 101 uses the bandwidth configured in the Coreset0 to send a downlink message to the terminal device 103. Since the bandwidth configured in the Coreset0 is small, the demodulation performance of the downlink message before the RRC connection is completed is poor, and the terminal device 103 cannot correctly decrypt the downlink message after receiving it.

[0057] The present application embodiment provides a resource configuration method, which can be applied to Figure 1 The communication system shown below refers to Figure 2 The process of a resource configuration method provided in an embodiment of the present application is described in detail.

[0058] S201: The network device generates a system message, wherein the system message includes resource indication information, wherein the resource indication information is used to indicate resources used by a target downlink message, and the target downlink message is a downlink message of the terminal device before completing a radio resource control RRC connection.

[0059] Optionally, the target downlink message includes at least one item or a combination of the following: a random access response message, a connection configuration message, and other system messages.

[0060] S202: The network device sends the system message to the terminal device.

[0061] In one embodiment, before the network device sends the system message to the terminal device, the method also includes: the network device sends main information to the terminal device, the main information including first resource configuration information; the system message also includes second resource configuration information, the bandwidth of the second resource indicated by the second resource configuration information is greater than the bandwidth of the first resource indicated by the first resource configuration information; the resource indication information is used to indicate that the resource used by the target downlink message is the first resource or the second resource.

[0062] In one implementation, the network device uses the bandwidth of the resources indicated by the resource indication information to send the target downlink message to the terminal device.

[0063] Specifically, when the resource indication information indicates that the resource used by the target downlink message is a first resource, the network device uses the bandwidth of the first resource to send the target downlink message to the terminal device before completing the RRC connection; when the resource indication information indicates that the resource used by the target downlink message is a second resource, the network device uses the bandwidth of the second resource to send the target downlink message to the terminal device before completing the RRC connection.

[0064] Optionally, the main information may be a main information block MIB, and the system message may be a system message type SIB1; the bandwidth of the first resource may be the bandwidth configured in the control resource set Coreset0 in the MIB, and the bandwidth of the second resource may be the bandwidth of the initial downlink bandwidth part DL BWP contained in the SIB1.

[0065] In one implementation, after completing the RRC connection, the network device sends downlink data to the terminal device using the bandwidth of the activated third resource, where the third resource is a resource configured by the network device in the connection configuration message; or

[0066] The network device sends downlink data to the terminal device using a bandwidth of a default resource, where the default resource is a resource configured by the network device by default in the connection configuration message; or

[0067] The network device uses the bandwidth of a second resource to send downlink data to the terminal device, where the second resource is the resource indicated by the second resource configuration information in the system message.

[0068] Specifically, when the RRC connection is established, the network device configures a third resource in the connection configuration message and activates the third resource. After completing the RRC connection, the network device uses the bandwidth of the activated third resource to send downlink data to the terminal device; or

[0069] When the RRC connection is established, the network device does not configure the third resource in the connection configuration message. After completing the RRC connection, the network device uses the bandwidth of the default resource in the connection configuration message to send downlink data to the terminal device; or

[0070] When the RRC connection is established, the network device does not configure the third resource and does not configure the default resource in the connection configuration message. After completing the RRC connection, the network device uses the bandwidth of the second resource indicated by the second resource configuration information in the system message to send downlink data to the terminal device.

[0071] According to the above, in the present application, the network device generates a system message and sends the system message to the terminal device; the system message contains resource indication information, and the resource indication information is used to indicate the resources used by the target downlink message, and the target downlink message is the downlink message of the terminal device before the completion of the radio resource control RRC connection. In this method, before the terminal device completes the radio resource control RRC connection, the network device can flexibly configure the resource indication information in the system message, and use the resources indicated by the resource indication information to transmit the target downlink message to the terminal device. This method can not only improve the demodulation performance of the target downlink message, but also ensure that the terminal device can correctly decode the target downlink message after receiving it.

[0072] Based on the above Figure 2 In the embodiment shown, the present application also provides an example of a resource configuration method. Before completing the establishment of the RRC connection, the resource indication information in the system message (taking SIB1 information as an example) is used to indicate that the resource used by the target downlink message is the first resource, and the network device uses the bandwidth of the first resource (taking the bandwidth configured in Coreset0 as an example) to send the target downlink message to the terminal device. The specific process of this implementation is as follows Figure 3 As shown:

[0073] Step 301: The network device sends main information (taking MIB information as an example) to the terminal device, and the terminal device receives the MIB information. The bandwidth size and position of Coreset0 are configured in the MIB message, and the Coreset0 is used to schedule system information.

[0074] Step 302: The network device generates system information (taking SIB1 information as an example), the resource indication information contained in the SIB1 indicates that the target information uses the Coreset0 resources, and the target downlink message is a downlink message of the terminal device before completing the radio resource control RRC connection.

[0075] Step 303: The network device sends the SIB1 information to the terminal device using the bandwidth configured in the Coreset0, and the terminal device receives the SIB1 information. The SIB1 also includes second resource configuration information (taking the initial DL BWP as an example), and the bandwidth of the initial DL BWP indicated by the second resource configuration information is greater than the bandwidth configured in the Coreset0.

[0076] The above steps S301-S303 are the process of the terminal device obtaining downlink system messages before establishing an RRC connection.

[0077] Step 304: The terminal device sends a random access request msg1 to the network device.

[0078] Step 305: After receiving the msg1, the network device sends a random access response msg2 to the terminal device. The msg2 is carried on the PDSCH. The network device determines that the resource indication information in the SIB1 indicates that the target downlink information uses the Coreset0 resource, and then the network device uses the bandwidth configured in the Coreset0 to send the msg2 to the terminal device. The terminal device detects the PDSCH on the downlink frequency domain resources used to carry the msg2, and then determines the position of the PDSCH on the frequency domain according to the scheduling information on the PDCCH, and receives the msg2 on the PDSCH.

[0079] Step 306: The terminal device sends a connection establishment request message msg3 to the network device, and the network device receives the msg3.

[0080] Step 307: The network device determines that the resource indication information contained in the SIB1 indicates that the target information uses the Coreset0 resource. The network device uses the bandwidth of the Coreset0 to send connection configuration information msg4 to the terminal device. After receiving the msg4, the terminal device enters a connected state.

[0081] Step 308: The terminal device sends a connection establishment completion message msg5 to the network device, and the network device receives the msg5.

[0082] The above steps S304-S308 are a random access process for the terminal device to establish the RRC connection, and the terminal device enters the RRC connection state from an idle state or an inactive state.

[0083] Step 309: The network device sends downlink data to the terminal device using the corresponding bandwidth according to the bandwidth configured in the msg4.

[0084] Specifically, after the network device determines that the terminal device is in a connected state, the method further includes:

[0085] According to the above-mentioned step Step307, if the network device determines that the third resource (taking BWP as an example) is configured in the msg4 and is in an activated state, the network device uses the bandwidth of the BWP to send downlink data to the terminal device; if the network device configures the third resource (taking BWP as an example) in the msg4 and is in an inactivated state, the network device uses the bandwidth of the default BWP to send downlink data to the terminal device, and the default resource is the resource configured by default by the network device in the connection configuration message; if the network device does not configure the third resource (taking BWP as an example) in the msg4, and the default BWP is not configured, the network device uses the bandwidth of the second resource (initial DL BWP) to send downlink data to the terminal device.

[0086] In this embodiment, the bandwidth size used for downlink transmission (the bandwidth configured in Coreset0) is the process of configuring the downlink bandwidth in the initial access process by default, and is the bandwidth size used for downlink messages executed in accordance with the 3GPP protocol standard. For terminal devices in poor channel conditions, after SIB1, the downlink message before completing the RRC connection uses the bandwidth size configured in Coreset 0, and it is very likely that the downlink message demodulation performance will be poor.

[0087] Based on the above Figure 2In the embodiment shown, the present application also provides another example of a resource configuration method. Before completing the establishment of the RRC connection, the resource indication information in the system message (taking SIB1 as an example) is used to indicate that the resource used by the target downlink message is a second resource, and the network device uses the bandwidth of the second resource (taking the bandwidth of the initial DLBWP as an example) to send the target downlink message to the terminal device. The specific process of this implementation is as follows Figure 4 As shown:

[0088] Step 401: The network device sends main information (taking MIB information as an example) to the terminal device, and the terminal device receives the MIB information. The bandwidth size and position of Coreset0 are configured in the MIB message, and the Coreset0 is used for scheduling system information.

[0089] Step 402: The network device generates system information (taking SIB1 information as an example), the resource indication information contained in SIB1 indicates that the target downlink information uses the resources of the initial DL BWP, and the target downlink message is the downlink message of the terminal device before completing the radio resource control RRC connection. The bandwidth of the initial DL BWP is greater than the bandwidth configured in Coreset0.

[0090] Step 403: The network device sends the SIB1 information to the terminal device using the bandwidth configured in the Coreset0, and the terminal device receives the SIB1 information.

[0091] In steps S401-S403, the network device sends the MIB information to the terminal device, and uses the bandwidth of Coreset0 in the MIB information to send the SIB1 information to the terminal device, thereby providing the required transmission resources for the message when the network device establishes the RRC connection with the terminal device.

[0092] Step 404: The terminal device sends a random access request msg1 to the network device.

[0093] Step 405: After receiving the msg1, the network device sends a random access response msg2 to the terminal device. The msg2 is carried on the PDSCH. The network device determines that the resource indication information in the SIB1 indicates that the target information uses the resources of the initial DL BWP, and then the network device uses the bandwidth of the initial DL BWP to send the msg2 to the terminal device. The terminal device detects the PDSCH on the downlink frequency domain resources used to carry the msg2, and then determines the position of the PDSCH on the frequency domain according to the scheduling information on the PDCCH, and receives the msg2 on the PDSCH.

[0094] Step 406: The terminal device sends a connection establishment request message msg3 to the network device, and the network device receives the msg3.

[0095] Step 407: The network device determines that the resource indication information included in the SIB1 indicates that the target information uses the resources of the initial DL BWP, and the network device uses the bandwidth of the initial DL BWP to send connection configuration information msg4 to the terminal device. After receiving the msg4, the terminal device enters a connected state.

[0096] Step 408: The terminal device sends a connection establishment completion message msg5 to the network device, and the network device receives the msg5.

[0097] The above steps S404-S408 are a random access process for establishing the RRC connection, and the terminal device enters the RRC connection state from the idle state or the inactive state.

[0098] Step 409: The network device sends downlink data to the terminal device using the corresponding bandwidth according to the bandwidth configured in the msg4.

[0099] Specifically, after the network device determines that the terminal device is in a connected state, the method further includes:

[0100] According to the above step Step 407, if the network device configures the third resource (taking BWP as an example) in the msg4 and it is activated, the network device uses the bandwidth of the BWP to send downlink data to the terminal device;

[0101] If the network device configures a third resource (taking BWP as an example) in the msg4 and it is in an inactivated state, the network device uses the default BWP bandwidth to send downlink data to the terminal device. The default resource is the resource configured by the network device by default in the connection configuration message.

[0102] If the network device has not configured the third resource (taking BWP as an example) in the msg4, and has not configured the default BWP, the network device uses the bandwidth of the second resource (initial DL BWP) to send downlink data to the terminal device.

[0103] In this embodiment, the network device adds resource indication information to the system message. According to the actual situation, the resource indication information can indicate the resources used by the downlink message of the terminal device before completing the RRC connection according to the actual situation of the channel where the terminal device is located. In this embodiment, the bandwidth of the initial DL BWP is larger than the bandwidth configured by the Coreset0. Therefore, in the case of poor channel conditions, the resource indication information indicates that the downlink message of the terminal device before completing the RRC connection uses the bandwidth of the initial DL BWP with a relatively large bandwidth, thereby improving the demodulation performance of the downlink message, thereby ensuring that the terminal device can correctly decrypt the downlink message after receiving it.

[0104] A schematic diagram of a bandwidth part BWP provided in an embodiment of the present application is as follows: Figure 5 As shown, under normal circumstances, the bandwidth configured in the Coreset0 is relatively small, and the bandwidth of the initial DL BWP includes and is greater than the bandwidth configured in the Coreset0. The present application flexibly configures resource indication information in the system message SIB1. Under normal circumstances, the resource indication information in the system message SIB1 indicates that the target downlink message uses the first resource, namely, the Coreset0. Therefore, after SIB1 and before the RRC connection is completed, the bandwidth used by the network device to send the target downlink message to the terminal device is the bandwidth configured in the Coreset0. When the channel quality of the terminal device is poor, the resource indication information in the system message SIB1 indicates that the target downlink message uses the second resource, namely, the initial DL BWP.
