Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information processing and acquisition method, device, terminal and network equipment. Background Art

[0002] Direct communication refers to the method by which adjacent terminals can transmit data in a short distance through a direct communication link (also called Sidelink or PC5 link or side link or bypass, referred to as SL). The wireless interface corresponding to Sidelink is called a direct communication interface (also called Sidelink interface or PC5 interface or side link interface or bypass interface).

[0003] The current 5th Generation (5G) New Radio (NR) direct communication interface only supports one frequency point / bandwidth part (Bandwidth Part, BWP), so it cannot meet the demand for improving the peak rate of services. In order to better meet the needs of services, the direct communication interface will be supported to use multiple frequencies / BWPs in the future. In this case, it is necessary to consider how to ensure that the direct communication interface logical channel can obtain the direct communication interface scheduling permission in time when there is a data transmission demand.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0142] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order.

For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone.

In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0144] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0145] The relevant concepts mentioned in this application are briefly described below.

[0146] 1. Cellular Network Communication

[0147] Traditional wireless communication uses cellular network communication, that is, the terminal and network equipment transmit uplink and downlink data / control information through the Uu interface.

[0148] 2. Buffer Status Reporting (BSR)

[0149] The 3GPP wireless communication system is a scheduling-based system. The base station allocates the time and frequency resources required for data transmission to the terminal device. The terminal receives downlink data or sends uplink data according to the scheduling command of the base station. Uplink data transmission is scheduled by the base station. After the base station scheduler determines the uplink resource allocation, it will notify the terminal through an uplink scheduling grant (UL grant). The basis for the base station scheduler to allocate uplink resources is the amount of uplink data to be sent by the terminal, that is, the buffer status of the terminal. The buffer is on the terminal side. If the base station wants to know this information, the terminal needs to send a BSR to the base station. The BSR classification and triggering mechanism are as follows:

[0150] Regular BSR: (1) Triggered when data with a higher priority than the data in the current buffer arrives or when data arrives in an empty buffer; (2) Triggered when the retxBSR-Timer times out and there is data in the buffer.

[0151] Periodic BSR: Periodic BSR is triggered when the periodicBSR-Timer times out.

[0152] Padding BSR: If the user equipment (UE) has resources available (Padding) in addition to the data to be transmitted when organizing the Media Access Control Protocol Data Unit (MAC PDU), the Padding BSR can be triggered.

[0153] 3. Scheduling Request (SR)

[0154] When a Regular BSR is triggered on the terminal direct communication interface and the logical channel scheduling request delay timer (logicalChannelSR-DelayTimer) is not running, an SR is triggered when any of the following conditions is met:

[0155] Condition 1: There is no uplink shared channel (UL-SCH) resource for new transmission;

[0156] Condition 2: There are UL-SCH resources for new transmissions and according to Logical Channel Prioritization (LCP), UL-SCH resources cannot carry SL-BSR MAC CE and its corresponding sub-header;

[0157] Condition 3: If the logical channel triggering the SL-BSR is configured with a subcarrier spacing list (sl-AllowedSCS-List) allowed by the direct communication link, but the sl-AllowedSCS-List does not contain the SCS of the UL-SCH resources that can be used for new data transmission;

[0158] Condition 4: If the logical channel that triggers the SL-BSR is configured with the maximum physical uplink shared channel duration (sl-MaxPUSCH-Duration) of the direct communication link, but the sl-MaxPUSCH-Duration does not include the PUSCH duration of the UL-SCH resources that can be used for new data transmission.

[0159] The current direct communication interface only supports one frequency point / bandwidth part (BandwidthPart, BWP). In the future, the direct communication interface will be supported to use multiple frequency points / BWPs. In this case, how to trigger BSR needs to be reconsidered.

[0160] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1 As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (UE), for example, it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems or a gateway station supporting satellite communication, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0161] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The information processing, acquisition method, device, terminal and network equipment provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0162] The embodiments of the present application provide an information processing and acquisition method, apparatus, terminal and network device, so that a logical channel with a direct communication interface having a data transmission requirement can obtain a direct communication interface scheduling license as soon as possible, thereby meeting the transmission delay requirement of the service.

[0163] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0164] like Figure 2 As shown, an embodiment of the present application provides an information processing method, which is executed by a terminal and includes:

[0165] Step S201, determining the direct communication interface frequency resources available for the direct communication interface logical channel;

[0166] It should be noted that the frequency resources mentioned in the embodiment of the present application include at least one of the following: frequency point, carrier, bandwidth part (BWP); based on this, it can be understood that the direct communication interface frequency resources include multiple frequency points, multiple carriers or multiple BWPs available to the direct communication interface logical channel.

[0167] Step S202: If the direct communication interface frequency resources do not include the frequency resources corresponding to the terminal direct communication interface scheduling permission, triggering a scheduling request or a direct communication interface buffer status report;

[0168] It should be noted that, when the direct communication interface frequency resources do not include the frequency resources corresponding to the terminal direct communication interface scheduling license, it means that the network device has not allocated available resources for the direct communication interface logical channel with data transmission requirements. At this time, the terminal needs to apply for direct communication interface resources for the direct communication interface logical channel; optionally, in one case, the terminal can trigger a direct communication interface buffer status report, and the direct communication interface buffer status report is reported to the network device through the Uu interface. The network device allocates appropriate resources to the terminal based on the received direct communication interface buffer status report; optionally, in another case, if the Uu interface does not have suitable resources to send the direct communication interface buffer status report, the direct communication interface buffer status report can also trigger a scheduling request, and the terminal sends the scheduling request to the network device through the Uu interface. The device allocates Uu interface resources to the terminal, and the terminal then uses the Uu interface resources to send a direct communication interface buffer status report; optionally, the terminal can also directly trigger a scheduling request, and the terminal sends a scheduling request on appropriate resources to request the network device for resources for the direct communication interface buffer status report or resources for the direct communication interface. If the network device allocates Uu interface resources, the terminal reports the direct communication interface buffer status report on the Uu interface resources allocated by the network device, and the network device allocates direct communication interface resources to the terminal based on the received direct communication interface buffer status report, so that the terminal can use the resources to transmit data in a logical channel with data transmission requirements; it can be seen that whether the terminal triggers a scheduling request or triggers a direct communication interface buffer status report, its purpose is to apply for direct communication interface resources for the direct communication interface logical channel.

[0169] It should be noted that by triggering a scheduling request or a direct communication interface buffer status report when the frequency resources corresponding to the terminal direct communication interface scheduling license are not included in the direct communication interface frequency resources, the logical channel with data transmission requirements of the direct communication interface can obtain the direct communication interface scheduling license as soon as possible, thereby meeting the transmission delay requirements of the service.

[0170] It should be noted that the terminal referred to in the embodiments of the present application refers to a direct communication sending terminal.

[0171] Optionally, in one implementation, the specific implementation of determining the direct communication interface frequency resources available for the direct communication interface logical channel includes at least one of the following:

[0172] A11. Determine, according to the configuration information received from the upper layer, the direct communication interface frequency resources available for the direct communication interface logical channel;

[0173] It should be noted that the action of determining the direct communication interface frequency resources available for the direct communication interface logical channel is performed by the lower layer of the terminal (for example, the MAC layer), and the higher layer of the terminal (for example, the vehicle to everything (V2X) layer or the proximity service (ProSe) layer or the direct communication interface signaling (PC5-S) layer) will store the relevant configuration, that is, the higher layer of the terminal can directly send the configuration information to the lower layer of the terminal, and the lower layer of the terminal determines the direct communication interface frequency resources available for the direct communication interface logical channel based on the configuration information.

[0174] Optionally, in one implementation, the configuration information includes at least one of the following:

[0175] A111, a first mapping relationship between a direct communication interface service identifier and a target layer 2 address (L2 ID);

[0176] It should be noted that the service identifier can be indicated by a service number, service index, etc.

[0177] A112, a second mapping relationship between a direct communication interface service identifier and a direct communication interface frequency resource;

[0178] A113, a third mapping relationship between a direct communication interface service identifier and a quality of service attribute (QoS profile);

[0179] A114. A fourth mapping relationship between quality of service attributes and direct communication interface frequency resources;

[0180] A115. A fifth mapping relationship among a layer 2 target address, a quality of service attribute, and a direct communication interface frequency resource.

[0181] It should be noted that the specific implementation of the terminal determining the direct communication interface frequency resources available for the direct communication interface logical channel is different depending on the content included in the configuration information. The following is an explanation of the specific implementation of the terminal determining the direct communication interface frequency resources available for the direct communication interface logical channel based on the configuration information.

[0182] Optionally, in an implementation manner, determining, according to the configuration information received from the higher layer, the direct communication interface frequency resources available for the direct communication interface logical channel includes at least one of the following:

[0183] A1101. If the configuration information includes the first mapping relationship and the second mapping relationship, determine a sixth mapping relationship between a target layer 2 address and a direct communication interface frequency resource according to the first mapping relationship and the second mapping relationship, and determine a direct communication interface frequency resource available to a direct communication interface logical channel according to the layer 2 target address to which the logical channel belongs and the sixth mapping relationship;

[0184] It should be noted that since the configuration information includes a first mapping relationship between the direct communication interface service identifier and the target layer 2 address and a second mapping relationship between the direct communication interface service identifier and the direct communication interface frequency resource, the mapping relationship between the target layer 2 address and the direct communication interface frequency resource can be obtained through these two mappings. Different logical channels belong to different target layer 2 addresses. The layer 2 address to which the logical channel belongs can be used to determine the direct communication interface frequency resources available for the logical channel in the mapping relationship between the target layer 2 address and the direct communication interface frequency resource.

[0185] A1102. If the configuration information includes the second mapping relationship, determine the direct communication interface frequency resources available to the direct communication interface logical channel according to the seventh mapping relationship between the logical channel and the direct communication interface service identifier and the second mapping relationship;

[0186] It should be noted that, since there is a corresponding relationship between the logical channel and the direct communication interface service identifier, the direct communication interface frequency resources available for the logical channel can be determined in the second mapping relationship through the direct communication interface service identifier corresponding to the logical channel.

[0187] A1103. If the configuration information includes the fourth mapping relationship, determine the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel and the fourth mapping relationship;

[0188] It should be noted that, since each logical channel corresponds to a different quality of service attribute (QoS Profile), the direct communication interface frequency resources available for the logical channel can be determined according to the fourth mapping relationship.

[0189] A1104. If the configuration information includes the second mapping relationship and the third mapping relationship, determine the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel, the second mapping relationship, and the third mapping relationship;

[0190] It should be noted that since the configuration information includes the second mapping relationship between the direct communication interface service identifier and the direct communication interface frequency resource and the third mapping relationship between the direct communication interface service identifier and the service quality attribute, the mapping relationship between the service quality attribute and the direct communication interface frequency resource can be obtained through these two mappings; and different logical channels have different service quality attributes corresponding to them. The terminal can determine the direct communication interface frequency resources available for the logical channel based on the service quality attributes corresponding to the logical channel.

[0191] A1105. If the configuration information includes the fifth mapping relationship, determine the direct communication interface frequency resources available for the direct communication interface logical channel according to the layer 2 target address and service quality attributes corresponding to the logical channel and the fifth mapping relationship.

[0192] It should be noted that since there is a corresponding relationship between the logical channel and the layer 2 target address and service quality attributes, if the configuration information provides a fifth mapping relationship between the layer 2 target address, the service quality attributes and the direct communication interface frequency resources, the terminal can determine the direct communication interface frequency resources available for the logical channel based on the mapping relationship between the layer 2 target address and the service quality attributes, according to the fifth mapping relationship between the layer 2 target address, the service quality attributes and the direct communication interface frequency resources.

[0193] A12. Processing the LCP mapping restriction parameter according to the logical channel priority corresponding to the direct communication interface logical channel, and determining the direct communication interface frequency resources available to the direct communication interface logical channel;

[0194] It should be noted that in this case, the terminal needs to first obtain the LCP mapping restriction parameters corresponding to the direct communication interface logical channel, and then determine the direct communication interface frequency resources available to the direct communication interface logical channel based on the LCP mapping restriction parameters; normally, the direct communication interface frequency resources available to the direct communication interface logical channel are directly included in the LCP mapping restriction parameters, that is, the direct communication interface frequency resources available to the direct communication interface logical channel are part of the LCP mapping restriction parameters.

[0195] Optionally, in one implementation, the terminal may obtain the LCP mapping restriction parameter in at least one of the following ways:

[0196] A121. Receive an LCP mapping restriction parameter corresponding to the direct communication interface logical channel from a network device, where the LCP mapping restriction parameter includes: a direct communication interface frequency resource available for the logical channel;

[0197] It should be noted that this situation shows that the LCP mapping restriction parameters are completely configured by the network device, that is, the direct communication interface frequency resources available for the logical channel are determined by the network device. In order to enable the network device to accurately determine the direct communication interface frequency resources available for the logical channel, optionally, in one implementation method, the terminal needs to send auxiliary information to the network device, and the auxiliary information is used to assist the network device in determining the LCP mapping restriction parameters. Preferably, the auxiliary information is used to assist the network device in determining the direct communication interface frequency resources available for the logical channel.

[0198] Optionally, if the terminal is in a Radio Resource Control (RRC) connected state, the network device sends the LCP mapping restriction parameter to the terminal via RRC signaling.

[0199] Optionally, the auxiliary information includes at least one of the following:

[0200] A1201, a first mapping relationship between a direct communication interface service identifier and a target layer 2 address;

[0201] A1202. A second mapping relationship between a direct communication interface service identifier and a direct communication interface frequency resource;

[0202] A1203, a third mapping relationship between the direct communication interface service identifier and the service quality attribute;

[0203] A1204. A fourth mapping relationship between quality of service attributes and direct communication interface frequency resources;

[0204] A1205. A fifth mapping relationship between a layer 2 target address, a service quality attribute combination, and a direct communication interface frequency resource.

[0205] Optionally, the auxiliary information may be determined based on terminal high-layer configuration information. Optionally, the auxiliary information may be reported via direct communication link terminal information (SidelinkUEInformation) or terminal assistance information (UEAssistanceInformation), or may be reported via an introduced new RRC message.

[0206] Furthermore, after receiving the auxiliary information, the network device needs to determine the direct communication interface frequency resources available for the logical channel based on the auxiliary information; optionally, the specific implementation of the network device determining the direct communication interface frequency resources available for the logical channel based on the auxiliary information is similar to the specific implementation principle of the terminal determining the direct communication interface frequency resources available for the logical channel based on the configuration information, and will not be repeated here.

[0207] A122. Receive configuration information from a high layer of the terminal, determine a first part of information in an LCP mapping restriction parameter corresponding to a logical channel according to the configuration information, and receive a second part of information in an LCP mapping restriction parameter from a network device, and determine a set of the first part of information and the second part of information as an LCP mapping restriction parameter corresponding to the logical channel; wherein the first part of information at least includes: a direct communication interface frequency resource available for the logical channel;

[0208] It should be noted that, in this case, the LCP mapping restriction parameters are jointly determined by the network device and the terminal, that is, the terminal determines a part of the LCP mapping restriction parameters, and the network device determines another part of the LCP mapping restriction parameters and sends them to the terminal, and finally the terminal can obtain the complete LCP mapping restriction parameters. Optionally, in this case, the direct communication interface frequency resources available for the logical channel in the LCP mapping restriction parameters are determined by the terminal, that is, the terminal determines the direct communication interface frequency resources available for the logical channel based on the high-level configuration information. The specific determination method can be found in the above description and will not be repeated here.

[0209] Optionally, in order to assist the network device in determining the second part of the information in the LCP mapping restriction parameters, the terminal usually needs to send target information to the network device, and the target information is used to assist the network device in determining the second part of the information in the LCP mapping restriction parameters. Optionally, the second part of the information may include sl-AllowedSCS-List and / or sl-MaxPUSCH-Duration, but the second part of the information does not include the direct communication interface frequency resources available for the direct communication interface logical channel. Optionally, the target information may include: information such as service quality attributes of the terminal direct communication interface service.

[0210] Optionally, in one implementation, the method further includes:

[0211] The LCP process is performed according to the direct communication interface frequency resources available for the direct communication interface logical channel.

[0212] That is, the terminal needs to consider the direct communication interface frequency resources available to the direct communication interface logical channel when performing LCP; optionally, in one implementation, the specific implementation of performing the LCP process according to the direct communication interface frequency resources available to the direct communication interface logical channel includes at least one of the following:

[0213] B11. For the direct communication interface scheduling permission, the target layer 2 address corresponding to the target object with the highest priority among the target objects is used as the selected target layer 2 address;

[0214] B12. For the selected target layer 2 address, when selecting a logical channel, a logical channel that meets the first condition is used as the target logical channel;

[0215] The target object includes a direct communication interface media access control unit and / or a logical channel that meets a first condition; the first condition at least includes: the direct communication interface frequency resources available to the direct communication interface logical channel include the frequency resources corresponding to the direct communication interface scheduling license.

[0216] Optionally, after the terminal obtains the direct communication interface scheduling permission, this step is performed only when the terminal currently has a logical channel for data transmission requirements and / or the direct communication interface frequency resources available to the MAC CE include the direct communication interface scheduling.

[0217] It should be noted that when B11 is executed alone, only the target layer 2 address needs to be selected; when B12 is executed alone, the logical channel under the target layer 2 address needs to be selected; when B11 and B12 are executed together, both the target layer 2 address and the logical channel need to be selected at the same time.

[0218] It should be noted that this process can be understood as: first, a direct communication interface media access control unit and / or a direct communication interface logical channel that meets the first condition must be determined, wherein the first condition, i.e., the direct communication interface frequency resources available to the direct communication interface media access control unit and / or the direct communication interface logical channel, include the frequency resources corresponding to the direct communication interface scheduling permission. Then, the target layer 2 address selection is performed based on the direct communication interface media access control unit and / or the logical channel, i.e., the target layer 2 address corresponding to the direct communication interface media access control unit and / or the logical channel with the highest priority among the direct communication interface media access control unit and / or the logical channel that meets the first condition is used as the selected target layer 2 address; further, optionally, if it is necessary to continue to select the logical channel, it is necessary to continue to select the logical channel that meets the first condition under the target layer 2 address based on the selected target layer 2 address, and perform direct communication interface resource allocation for the logical channel.

[0219] The specific implementation of the embodiments of the present application is illustrated below with examples.

[0220] Application scenario 1: The terminal determines the direct communication interface frequency resources available for the direct communication interface logical channel based on the configuration information

[0221] like Figure 3 As shown, the specific implementation process includes:

[0222] Step 31, the direct communication sending terminal obtains its own high-level configuration information;

[0223] The configuration information includes one or more of the following:

[0224] A first mapping relationship between a direct communication interface service identifier and a target layer 2 address;

[0225] A second mapping relationship between a direct communication interface service identifier and a direct communication interface frequency resource;

[0226] A third mapping relationship between the direct communication interface service identifier and the service quality attribute;

[0227] a fourth mapping relationship between quality of service attributes and direct communication interface frequency resources;

[0228] A fifth mapping relationship among layer 2 target address, quality of service attribute and direct communication interface frequency resource.

[0229] Step 32: The direct communication sending terminal determines the direct communication interface frequency resources available for the direct communication interface logical channel based on the configuration information;

[0230] Optionally, the direct communication interface frequency resource may be represented in the form of a direct communication interface frequency resource list.

[0231] Optionally, a specific implementation manner in which the direct communication sending terminal determines the direct communication interface frequency resources available for the direct communication interface logical channel includes but is not limited to at least one of the following:

[0232] If the configuration information includes the first mapping relationship and the second mapping relationship, determine a sixth mapping relationship between the target layer 2 address and the direct communication interface frequency resource according to the first mapping relationship and the second mapping relationship, and determine the direct communication interface frequency resource available to the direct communication interface logical channel according to the layer 2 target address to which the logical channel belongs and the sixth mapping relationship;

[0233] If the configuration information includes the second mapping relationship, determining the direct communication interface frequency resources available to the direct communication interface logical channel according to the seventh mapping relationship between the logical channel and the direct communication interface service identifier and the second mapping relationship;

[0234] If the configuration information includes the fourth mapping relationship, determining the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel and the fourth mapping relationship;

[0236] If the configuration information includes the fifth mapping relationship, the direct communication interface frequency resources available for the direct communication interface logical channel are determined according to the layer 2 target address and the service quality attribute corresponding to the logical channel and the fifth mapping relationship.

[0237] Step 33: The direct communication sending terminal determines whether a scheduling request or a direct communication interface buffer status report needs to be triggered;

[0238] It should be noted that if the direct communication interface frequency resources do not include the frequency resources corresponding to the terminal direct communication interface scheduling permission, the direct communication interface buffer status report is triggered or the direct communication interface scheduling request is triggered. Further, if the direct communication interface buffer status report is triggered, but there are no available resources in the current Uu interface, it is determined that the scheduling request needs to be triggered.

[0239] Step 34: The direct communication sending terminal sends a scheduling request or a direct communication interface buffer status report on the Uu interface;

[0240] It should be noted that if the terminal wants to send a direct communication interface buffer status report, the specific steps are as follows: if the terminal Uu interface UL has available resources, the resources can be used to send a direct communication interface buffer status report; if the terminal Uu interface UL has no available resources, the terminal can request Uu interface UL resources from the network device through the Uu interface scheduling request resource, and once the Uu interface UL resources are obtained, the UL resources can be used to send a direct communication interface buffer status report.

[0241] If the terminal needs to send a direct communication interface scheduling request, the terminal may directly send the request on the direct communication interface scheduling request resource configured by the network device.

[0242] Step 35: The network device allocates resources to the terminal direct communication interface;

[0243] The network device receives the direct communication interface buffer status report sent by the terminal and directly allocates the direct communication interface resources to the terminal. The terminal receives the direct communication interface resources and executes the LCP process to transmit information; or, the network device receives the direct communication interface scheduling request sent by the terminal and allocates the direct communication interface data transmission resources to the terminal or allocates the Uu interface resources for transmitting the direct communication interface buffer status report to the terminal.

[0244] Application 2: Configuring LCP Mapping Limit Parameters on Network Devices

[0245] like Figure 4 As shown, the specific implementation process includes:

[0246] Step 41, the direct communication sending terminal obtains its own high-level configuration information;

[0247] The configuration information includes one or more of the following:

[0248] A first mapping relationship between a direct communication interface service identifier and a target layer 2 address;

[0249] A second mapping relationship between a direct communication interface service identifier and a direct communication interface frequency resource;

[0250] A third mapping relationship between the direct communication interface service identifier and the service quality attribute;

[0251] a fourth mapping relationship between quality of service attributes and direct communication interface frequency resources;

[0252] A fifth mapping relationship among layer 2 target address, quality of service attribute and direct communication interface frequency resource.

[0253] Step 42: The direct communication sending terminal reports the auxiliary information;

[0254] It should be noted that the auxiliary information is usually determined by the configuration information, and the auxiliary information includes at least one of the following:

[0255] A first mapping relationship between a direct communication interface service identifier and a target layer 2 address;

[0256] A second mapping relationship between a direct communication interface service identifier and a direct communication interface frequency resource;

[0257] A third mapping relationship between the direct communication interface service identifier and the service quality attribute;

[0258] a fourth mapping relationship between quality of service attributes and direct communication interface frequency resources;

[0259] A fifth mapping relationship among a layer 2 target address, a quality of service attribute combination, and a direct communication interface frequency resource.

[0260] It should be noted that the auxiliary information reporting may be reported using the existing SidelinkUEInformation or UEAssistanceInformation, or may be reported using a newly introduced RRC message.

[0261] Step 43: The network device determines an LCP mapping restriction parameter corresponding to the direct communication interface logical channel, where the LCP mapping restriction parameter at least includes a direct communication interface frequency resource available for the direct communication interface logical channel.

[0262] Optionally, the direct communication interface frequency resource may be represented in the form of a direct communication interface frequency resource list.

[0263] Optionally, the network device determines the direct communication interface frequency resources available for the direct communication interface logical channel according to the auxiliary information in step 42. The specific implementation of determining the direct communication interface frequency resources available for the direct communication interface logical channel includes but is not limited to at least one of the following:

[0264] If the auxiliary information includes the first mapping relationship and the second mapping relationship, determine a sixth mapping relationship between the target layer 2 address and the direct communication interface frequency resource according to the first mapping relationship and the second mapping relationship, and determine the direct communication interface frequency resource available to the direct communication interface logical channel according to the layer 2 target address to which the logical channel belongs and the sixth mapping relationship;

[0265] If the auxiliary information includes the second mapping relationship, determining the direct communication interface frequency resources available for the direct communication interface logical channel according to the seventh mapping relationship between the logical channel and the direct communication interface service identifier and the second mapping relationship;

[0266] If the auxiliary information includes the fourth mapping relationship, determining the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel and the fourth mapping relationship;

[0267] If the auxiliary information includes the second mapping relationship and the third mapping relationship, determining the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel, the second mapping relationship, and the third mapping relationship;

[0268] If the auxiliary information includes the fifth mapping relationship, the direct communication interface frequency resources available for the direct communication interface logical channel are determined according to the layer 2 target address and service quality attribute corresponding to the logical channel and the fifth mapping relationship.

[0269] Step 44: The network device sends the LCP mapping restriction parameter to the terminal;

[0270] It should be noted that if the terminal is in an RRC connected state, the LCP mapping restriction configuration is sent via RRC signaling. The terminal determines the LCP mapping restriction parameters corresponding to the direct communication interface logical channel according to the RRC signaling sent by the network device. Among them, the LCP mapping restriction parameters include at least the direct communication interface frequency resources available to the direct communication interface logical channel.

[0271] Step 45: The direct communication sending terminal determines whether it is necessary to trigger a scheduling request or a direct communication interface buffer status report;

[0272] It should be noted that if the direct communication interface frequency resources do not include the frequency resources corresponding to the terminal direct communication interface scheduling permission, the direct communication interface buffer status report is triggered or the direct communication interface scheduling request is triggered. Further, if the direct communication interface buffer status report is triggered, but there are no available resources in the current Uu interface, it is determined that the scheduling request needs to be triggered.

[0273] Step 46: The direct communication sending terminal sends a scheduling request or a direct communication interface buffer status report on the Uu interface;

[0274] It should be noted that if the terminal wants to send a direct communication interface buffer status report, the specific steps are as follows: if the terminal Uu interface UL has available resources, the resources can be used to send a direct communication interface buffer status report; if the terminal Uu interface UL has no available resources, the terminal can request Uu interface UL resources from the network device through the Uu interface scheduling request resource, and once the Uu interface UL resources are obtained, the UL resources can be used to send a direct communication interface buffer status report.

[0275] If the terminal needs to send a direct communication interface scheduling request, the terminal may directly send the request on the direct communication interface scheduling request resource configured by the network device.

[0276] Step 47: The network device allocates resources to the terminal direct communication interface;

[0277] The network device receives the direct communication interface buffer status report sent by the terminal and directly allocates the direct communication interface resources to the terminal. The terminal receives the direct communication interface resources and executes the LCP process to transmit information; or, the network device receives the direct communication interface scheduling request sent by the terminal and allocates the direct communication interface data transmission resources to the terminal or allocates the Uu interface resources for transmitting the direct communication interface buffer status report to the terminal.

[0278] Application 3: LCP mapping restriction parameters are determined by the terminal and network equipment

[0279] like Figure 5 As shown, the specific implementation process includes:

[0280] Step 51, the direct communication sending terminal obtains its own high-level configuration information;

[0281] The configuration information includes one or more of the following:

[0282] A first mapping relationship between a direct communication interface service identifier and a target layer 2 address;

[0283] A second mapping relationship between a direct communication interface service identifier and a direct communication interface frequency resource;

[0284] A third mapping relationship between the direct communication interface service identifier and the service quality attribute;

[0285] a fourth mapping relationship between quality of service attributes and direct communication interface frequency resources;

[0286] A fifth mapping relationship among layer 2 target address, quality of service attribute and direct communication interface frequency resource.

[0287] Step 52: reporting target information;

[0288] It should be noted that, in this step, the target information reporting may report information such as the QoS profile of the terminal direct communication interface service.

[0289] Step 53: The network device determines the second part of information in the LCP mapping restriction parameter;

[0290] The second part of information may include sl-AllowedSCS-List and / or sl-MaxPUSCH-Duration, but does not include the direct communication interface frequency resources available for the logical channel.

[0291] Step 54: The network device sends the second part of information in the LCP mapping restriction parameter to the terminal;

[0292] Step 55: The terminal determines the first part of information in the LCP mapping restriction parameter;

[0293] It should be noted that the first part of the information in the LCP mapping restriction parameter at least includes the direct communication interface frequency resources available for the logical channel.

[0294] Optionally, the direct communication interface frequency resource may be represented in the form of a direct communication interface frequency resource list.

[0295] The direct communication sending terminal determines the direct communication interface frequency resources available for the direct communication interface logical channel based on the configuration information of the high layer.

[0296] Optionally, a specific implementation manner in which the direct communication sending terminal determines the direct communication interface frequency resources available for the direct communication interface logical channel includes but is not limited to at least one of the following:

[0297] If the configuration information includes the first mapping relationship and the second mapping relationship, determine a sixth mapping relationship between the target layer 2 address and the direct communication interface frequency resource according to the first mapping relationship and the second mapping relationship, and determine the direct communication interface frequency resource available to the direct communication interface logical channel according to the layer 2 target address to which the logical channel belongs and the sixth mapping relationship;

[0298] If the configuration information includes the second mapping relationship, determining the direct communication interface frequency resources available to the direct communication interface logical channel according to the seventh mapping relationship between the logical channel and the direct communication interface service identifier and the second mapping relationship;

[0299] If the configuration information includes the fourth mapping relationship, determining the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel and the fourth mapping relationship;

[0300] If the configuration information includes the second mapping relationship and the third mapping relationship, determining the direct communication interface frequency resources available for the direct communication interface logical channel according to the quality of service attribute corresponding to the logical channel, the second mapping relationship, and the third mapping relationship;

[0301] If the configuration information includes the fifth mapping relationship, the direct communication interface frequency resources available for the direct communication interface logical channel are determined according to the layer 2 target address and the service quality attribute corresponding to the logical channel and the fifth mapping relationship.

[0302] The terminal uses the second part of information configured by the network and the first part of information determined by the terminal itself as complete LCP mapping restriction parameters corresponding to the logical channel.

[0303] Step 56: The direct communication sending terminal determines whether it is necessary to trigger a scheduling request or a direct communication interface buffer status report;

[0304] It should be noted that if the direct communication interface frequency resources do not include the frequency resources corresponding to the terminal direct communication interface scheduling permission, the direct communication interface buffer status report is triggered or the direct communication interface scheduling request is triggered. Further, if the direct communication interface buffer status report is triggered, but there are no available resources in the current Uu interface, it is determined that the scheduling request needs to be triggered.

[0305] Step 57: The direct communication sending terminal sends a scheduling request or a direct communication interface buffer status report on the Uu interface;

[0306] It should be noted that if the terminal wants to send a direct communication interface buffer status report, the specific steps are as follows: if the terminal Uu interface UL has available resources, the resources can be used to send a direct communication interface buffer status report; if the terminal Uu interface UL has no available resources, the terminal can request Uu interface UL resources from the network device through the Uu interface scheduling request resource, and once the Uu interface UL resources are obtained, the UL resources can be used to send a direct communication interface buffer status report.

[0307] If the terminal needs to send a direct communication interface scheduling request, the terminal may directly send the request on the direct communication interface scheduling request resource configured by the network device.

[0308] Step 58: The network device allocates resources to the terminal direct communication interface;

[0309] The network device receives the direct communication interface buffer status report sent by the terminal and directly allocates the direct communication interface resources to the terminal. The terminal receives the direct communication interface resources and executes the LCP process to transmit information; or, the network device receives the direct communication interface scheduling request sent by the terminal and allocates the direct communication interface data transmission resources to the terminal or allocates the Uu interface resources for transmitting the direct communication interface buffer status report to the terminal.

[0310] It should be noted that the embodiments of the present application can ensure that when the current UL-SCH cannot meet the service transmission requirements, the terminal can initiate the SR or BSR process as soon as possible to obtain direct communication interface resources to meet the service delay requirements.

[0311] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems.
