Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an information transmission and resource allocation method, apparatus, terminal equipment, and network equipment. Background Technology

[0002] Currently, the configuration method for the direct communication interface resource pool in 5G New Radio is as follows: A common resource pool can be used for direct communication (Sidelink, SL, also known as bypass) interface communication and SL discovery. In addition, a dedicated SL discovery resource pool has been introduced for SL discovery.

[0003] In the future, with the introduction of more complex scenarios such as UE-to-UE relay (U2U relay), and considering power saving at the receiving end, more dedicated resource pools may be introduced. For example, there might be a dedicated resource pool for UE-to-Network relay (U2Nrelay) discovery and a dedicated resource pool for U2U relay discovery. Furthermore, due to their different roles, the available resource allocation modes for relay UEs and remote UEs may differ, thus requiring enhancement of the existing direct communication interface resource allocation mechanism.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0149] The terms “first,” “second,” etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0152] The embodiments of this application are described below with reference to the accompanying drawings. The resource configuration method, apparatus, network device, and terminal device provided in the embodiments of this application can be applied to wireless communication systems. This wireless communication system can be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will understand that the 5G NR system is merely an example and not a limitation.

[0153] See Figure 1 , Figure 1 This is a structural diagram of a network system that can be applied to the embodiments of this application, such as... Figure 1 As shown, the system includes a user terminal 11 and a base station 12. The user terminal 11 can be a user equipment (UE), such as a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device. It should be noted that the specific type of user terminal 11 is not limited in this embodiment. The base station 12 can be a 5G or later version base station (e.g., gNB, 5G NR NB), or a base station in other communication systems, also referred to as a node B. It should be noted that this embodiment only uses a 5G base station as an example, but the specific type of base station 12 is not limited.

[0154] This application provides an information transmission and resource allocation method, apparatus, terminal device, and network device to solve the problem that existing direct communication interface resource allocation mechanisms cannot guarantee reasonable resource allocation for direct communication interfaces.

[0155] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0156] like Figure 2 As shown, this embodiment of the invention provides an information transmission method, executed by a terminal device, including:

[0157] Step S201: Send auxiliary information to the network device;

[0158] It should be noted that the auxiliary information is used to assist the network device in configuring the resources of the direct communication interface for the terminal device (or, the auxiliary information enables the network device to allocate resources of the direct communication interface for the terminal device).

[0159] It should be noted that the auxiliary information includes at least one of the following:

[0160] A11. The correspondence between the target address of the direct communication interface and the message type of the direct communication interface message;

[0161] It should be noted that the target address of the direct communication interface can be represented by the L2 target address of the direct communication interface. The correspondence between the target address of the direct communication interface and the message type of the direct communication interface message can be a correspondence list, that is, the correspondence list includes the target address of the direct communication interface and the message type of the direct communication interface message corresponding to each target address of the direct communication interface.

[0162] A12. The identity information of the terminal device.

[0163] It should be noted that by sending auxiliary information to the network device carrying the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message and / or the identity information of the terminal device, the network device can be assisted in configuring the resources of the direct communication interface for the terminal device. This can ensure that the resources of the direct communication interface are allocated reasonably, so that the resource allocation of the direct communication interface meets the needs of all application scenarios.

[0164] Optionally, the auxiliary information transmission method in the embodiments of this application includes any of the following:

[0165] B11, Direct Communication Terminal Information (SidelinkUE Information, SUI);

[0166] B12, UE Assistant Information (UAI) for direct terminal communication interface;

[0167] B13. Radio Resource Control (RRC) signaling for direct communication interfaces;

[0168] It should be noted that the direct communication interface RRC signaling is a newly introduced uplink RRC signaling for transmitting the above-mentioned A11 and / or A12 in this embodiment of the application.

[0169] Optionally, the message type of the direct communication interface message mentioned in the embodiments of this application includes one of the following:

[0170] C11. Direct communication interface discovery message;

[0171] C12, Direct Communication Interface Communication Messages.

[0172] Optionally, depending on the application scenario, the message type of the direct communication interface message may further indicate first information, which is used to indicate the application scenario corresponding to the terminal's identity identifier. For example, the message type may include the first information.

[0173] Optionally, depending on the application scenario, the identity information of the terminal device may further indicate first information, which is used to indicate the application scenario corresponding to the identity of the terminal device. For example, the identity information of the terminal device includes the first information.

[0174] It should be noted that, generally when the auxiliary information includes the above-mentioned A11 and A12, preferably, in order to save signaling overhead, the first information can be carried only in the message type or identity information.

[0175] Specifically, the first information includes at least one of the following:

[0176] D11, Direct Communication Transmission;

[0177] In other words, in this case, the application scenario for the terminal device is direct communication transmission.

[0178] It should be noted that this direct communication transmission refers to the existing conventional direct communication transmission, that is, two terminals directly receiving or sending data through the PC5 interface.

[0179] D12, First Relay;

[0180] It should be noted that the first relay includes at least one of the following:

[0181] D121, Terminal device to network device relay (U2N relay);

[0182] D122, Terminal-to-Terminal relay (U2U relay).

[0183] In other words, in this case, the application scenario of the terminal device is a relay scenario, and the terminal device will indicate a U2N relay scenario, a U2U relay scenario, or a U2N relay scenario and a U2U relay scenario.

[0184] It should also be noted that, since U2N relays and U2U relays can be further divided into Layer 2 (L2) and Layer 3 (L3), this first relay also includes at least one of the following:

[0185] Layer 2, First Trunk;

[0186] Layer 3, first relay.

[0187] In other words, the first information may only indicate that the identity of the terminal device corresponds to a U2N relay scenario and / or a U2U relay scenario; furthermore, the first information may also indicate which layer of relay the identity of the terminal device corresponds to in U2N relay and / or U2U relay.

[0188] Optionally, the identity information of the terminal device includes one of the following:

[0189] E11, Remote UE;

[0190] E12, relay UE;

[0191] E13, Direct Communication Terminal (SL UE).

[0192] Furthermore, it should be noted that when the auxiliary information carries the identity information of the terminal device and the identity information of the terminal device indicates that the terminal is a relay terminal, the auxiliary information also carries the duplex capability indication information supported by the relay terminal in the direct communication interface.

[0193] The duplex capability indication information is used to indicate whether the relay terminal supports full-duplex or half-duplex on the direct communication interface.

[0194] It should be noted that the duplex capability indication information can assist the network in selecting resource allocation strategies when allocating resources. For example, network devices can decide whether to allow terminals to send and receive data simultaneously based on the duplex capability indication information.

[0195] Optionally, after receiving the auxiliary information, the network device allocates resources for the direct communication interface of the terminal device. Specifically, the network device allocates resources for the direct communication interface of the terminal device using at least one of the following methods:

[0196] F11. If the message types of the direct communication interface messages corresponding to different target addresses of the terminal device's direct communication interface are different, and the resource pools corresponding to the different message types are different, then resources in different resource pools shall be allocated to the different target addresses.

[0197] It should be noted that network devices pre-configure different resource pools for different message types, and when allocating resources for different target addresses corresponding to different direct communication interface messages, they select resources from different resource pools.

[0198] F12, Different terminal devices are configured with different resource allocation modes for different identity identification information;

[0199] It should be noted that this situation involves configuring different resource allocation modes for terminal devices with different identities. For example, U2U remote UEs can only use the terminal's self-selected resource allocation mode (i.e., mode 2), while U2U relay UEs can be configured to use the network-scheduled resource allocation mode (i.e., mode 1) or mode 2.

[0200] F13. Different terminals use different resource allocation strategies for different identity identification information;

[0201] It should be noted that this situation involves configuring different resource allocation strategies for terminal devices with different identities. For example, when the resource allocation strategy is to consider whether to consider duplex capability, for U2U relay UE, its duplex / half-duplex capability needs to be considered when allocating resources, while for remote UE, this capability is not considered.

[0202] Optionally, after the network device allocates resources to the terminal and obtains the first configuration, it should also send the first configuration to the terminal device; further, the transmission method of the first configuration includes one of the following:

[0203] RRC reconfiguration message;

[0204] The terminal sends downlink RRC messages to the network interface (i.e., the Uu interface);

[0205] It should be noted that the downlink RRC message of the Uu interface is a new downlink RRC message introduced in this application for transmitting the first configuration.

[0206] Specifically, the first configuration includes at least one of the following:

[0207] H11. Based on the terminal device, indicate the configuration information corresponding to the terminal device;

[0208] It should be noted that in this case, the configuration information is distinguished by the terminal device, that is, one terminal device corresponds to one type of configuration information (or one type of configuration information).

[0209] H12. The target address of each direct communication interface of the terminal device indicates the configuration information corresponding to the target address of the direct communication interface;

[0210] It should be noted that in this case, the configuration information is distinguished by the target address of the direct communication interface. That is, one target address of the communication interface corresponds to one type of configuration information. In other words, the network device will assign several types of configuration information to the terminal device based on the number of target addresses of the direct communication interfaces.

[0211] H13. The configuration information corresponding to the first parameter is indicated based on the first parameter of the terminal device;

[0212] It should be noted that in this case, the configuration information is distinguished by the first parameter. That is, one first parameter corresponds to one type of configuration information. In other words, the network device will assign several types of configuration information to the terminal device based on the number of first parameters it corresponds to.

[0213] It should be noted that the first parameter includes: the message type and / or identification information of the direct communication interface message.

[0214] H14. The first parameter under each target address of the direct communication interface of the terminal device indicates the configuration information corresponding to the first parameter;

[0215] It should be noted that in this case, the configuration information is distinguished by the first parameter under each target address. That is, one target address corresponds to one or more first parameters, and one first parameter corresponds to one type of configuration information. In other words, the direct communication interface of the terminal device corresponds to several target addresses, and the network device assigns the configuration information corresponding to each first parameter under these target addresses to the terminal device.

[0216] Specifically, the configuration information mentioned in the embodiments of this application includes at least one of the following: resource allocation mode and time-frequency resource configuration.

[0217] The specific applications of this application are illustrated below.

[0218] Specific Application Scenario 1: The auxiliary information only carries the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message.

[0219] like Figure 3 As shown, taking the communication between the terminal and the base station as an example, the specific implementation process in this case is as follows:

[0220] Step S301: Report auxiliary information;

[0221] The terminal sends auxiliary information to the base station. The auxiliary information needs to carry the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message.

[0222] The auxiliary information may be SUI, UAI, or other newly introduced uplink RRC signaling.

[0223] Specifically, the message type of the direct communication interface message can be, but is not limited to, one of the following: discovery message, communication message. Depending on the application scenario, the message type of the direct communication interface may further include first information, which indicates the application scenario corresponding to the terminal's identity identifier. Specifically, the application scenarios mentioned in this application can be, but are not limited to, one or a combination of the following:

[0224] SL transmission;

[0225] U2N relay, specifically, in this scenario, can be further divided into L2U2N relay scenario and L3 U2Nrelay scenario;

[0226] U2U relay, specifically, can be further divided into L2U2U relay scenario and L3 U2Urelay scenario.

[0227] For example:

[0228] The correspondence between the target address of the direct communication interface and the message type of the direct communication interface message carried in the above auxiliary information may specifically include the following:

[0229] L2destination ID X, whose corresponding direct communication interface message type is L2 U2U relaydiscovery message;

[0230] The L2destination ID Y corresponds to the L3 U2N relaydiscovery message as its direct communication interface message.

[0231] The L2destination ID Z corresponds to a sidelinkcommunication message as its direct communication interface message.

[0232] Step S302, configure signaling feedback;

[0233] After receiving the auxiliary information, the base station can perform different operations on the terminal based on the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message carried in the auxiliary information. Specific operations may include, but are not limited to, the following:

[0234] If different target addresses correspond to different message types, and the message pools corresponding to the different message types are different, then when the network allocates resources for the direct communication interface, it can allocate resources from different resource pools to different target addresses.

[0235] After receiving the auxiliary information and determining the configuration, the base station also needs to send configuration signaling to the terminal. This configuration signaling can be an existing RRC reconfiguration message or a newly introduced downlink RRC message. The content of the configuration signaling can be, but is not limited to, one of the following:

[0236] 1. The resource allocation mode and / or time-frequency resource configuration used by the terminal;

[0237] 2. Based on the direct communication interface, each target address indicates the resource allocation mode and / or time-frequency resource configuration used by the target address of the terminal;

[0238] 3. Based on the message type and / or identification information of the direct communication interface message, indicate the resource allocation mode and / or time-frequency resource configuration corresponding to the message type and / or identification information of the direct communication interface message;

[0239] 4. Each target address of the direct communication interface indicates the resource allocation mode and / or time-frequency resource configuration corresponding to the message type and / or identity information of the direct communication interface message under the target address.

[0240] For example:

[0241] Assuming the terminal sending auxiliary information supports both U2U relay and U2N relay, and that U2U relay discovery and U2N relay discovery correspond to different resource pools, the base station can instruct the terminal to use specific resources for each target address based on the direct communication interface. The resources used by the target address corresponding to U2U relay discovery and the resources used by the target address corresponding to U2N relay discovery belong to different resource pools.

[0242] Specific Application Scenario 2: The auxiliary information carries the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message, as well as the identity information of the terminal device.

[0243] Taking terminal-base station communication as an example, the specific implementation process in this case is as follows:

[0244] Step S301: Report auxiliary information;

[0245] The terminal sends auxiliary information to the base station. The auxiliary information needs to carry the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message, as well as the terminal's identity information.

[0246] The auxiliary information may be SUI, UAI, or other newly introduced uplink RRC signaling.

[0247] Specifically, the message type of the direct communication interface message can be, but is not limited to, one of the following: discovery message, communication message. The terminal's identity information can be, but is not limited to, one of the following: remote UE, relay UE, SL UE. The message type of the direct communication interface message and / or the terminal's identity information may further include first information, which is used to indicate the application scenario corresponding to the terminal's identity. Specifically, the application scenarios mentioned in this application can be, but are not limited to, one or a combination of the following:

[0248] SL transmission;

[0249] U2N relay, specifically, in this scenario, can be further divided into L2 U2N relay scenario and L3 U2N relay scenario;

[0250] U2U relay, specifically, can be further divided into L2 U2U relay scenario and L3 U2U relay scenario.

[0251] Optionally, if the identification information indicates that the terminal is a relay terminal, the auxiliary information also needs to include information indicating the duplex capability supported by the relay terminal in the direct communication interface.

[0252] For example:

[0253] Assume three terminals, UE1, UE2, and UE3, send auxiliary information to the base station. Wherein:

[0254] UE1 sends auxiliary information to the base station, which carries L2destination ID X. The message type of the corresponding direct communication interface message is L2 U2U relay discovery message, and the corresponding identity information can be a relay UE. The relay UE only supports half-duplex.

[0255] UE2 sends auxiliary information to the base station, which carries L2destination ID Y. The message type of the direct communication interface message corresponding to it is L3 U2N relay discovery message, and the corresponding identity information can be remote UE.

[0256] UE3 sends auxiliary information to the base station, which carries L2destination ID Z. The message type of the direct communication interface message corresponding to it is a sidelink communication message, and the corresponding identity information can be SL UE.

[0257] Step S302, configure signaling feedback;

[0258] After receiving the auxiliary information, the base station can perform different operations on the terminal based on the correspondence between the target address of the direct communication interface and the message type of the direct communication interface message carried in the auxiliary information, and the terminal's identity information. The specific operations can be, but are not limited to, one or a combination of the following:

[0259] 1. If different target addresses correspond to different message types, and the message pools corresponding to the different message types are different, then when the network performs direct communication interface resource allocation, it can allocate resources from different resource pools to different target addresses.

[0260] 2. Configure different resource allocation modes for terminals with different identities. For example, restrict U2Uremote UEs to use only mode 2, while U2U relay UEs can be configured to use either mode 1 or mode 2;

[0261] 3. Different resource allocation strategies are adopted for terminals with different identities. For example, when allocating resources for U2U relay UEs, their full-duplex / half-duplex capabilities need to be considered, while for remote UEs, this capability is not considered.

[0262] After receiving the auxiliary information and determining the configuration, the base station also needs to send configuration signaling to the terminal. This configuration signaling can be an existing RRC reconfiguration message or a newly introduced downlink RRC message. The content of the configuration signaling can be, but is not limited to, one of the following:

[0263] 1. The resource allocation mode and / or time-frequency resource configuration used by the terminal;

[0264] 2. Based on the direct communication interface, each target address indicates the resource allocation mode and / or time-frequency resource configuration used by the target address of the terminal;

[0265] 3. Based on the message type and / or identification information of the direct communication interface message, indicate the resource allocation mode and / or time-frequency resource configuration corresponding to the message type and / or identification information of the direct communication interface message;

[0266] 4. Each target address of the direct communication interface indicates the resource allocation mode and / or time-frequency resource configuration corresponding to the message type and / or identity information of the direct communication interface message under the target address.

[0267] For example:

[0268] Regarding UE1 and UE2 mentioned in the example of step S401, if the protocol restricts U2U remote UEs to only use mode 2, then the base station will only allow UE1 to be configured to use mode 2. However, since UE1 is a relay UE, the base station can determine its resource allocation mode as mode 1 or mode 2 based on the network implementation.

[0269] Furthermore, if the base station configures UE2 to use mode 1, and if UE2 only supports half-duplex mode, then when the base station receives the Sidelink scheduling request (SR) / buffer status report (BSR) sent by UE2, it will try to avoid allocating resources to UE2 on different direct communication interfaces (also known as PC5 interfaces) at the same time.

[0270] It should be noted that this method, as described in the embodiments of this application, can ensure reasonable resource allocation for direct communication interfaces in complex scenarios.
