Description

Information acquisition and transmission method, device, terminal and network equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 10, 2023, with application number 202311006175.9 and application name “Information acquisition, transmission method, device, terminal and network equipment”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an information acquisition and transmission method, apparatus, terminal, and network equipment. Background Art

[0003] In order to improve the peak rate of the direct communication interface, a carrier aggregation (CA) mechanism is introduced in the direct communication interface (Sidelink, SL). The terminals of the fifth generation (5Generation, 5G) mobile communication new air interface (New Radio, NR) Rel-18 version and the versions before Rel-18 only support one direct communication interface carrier, but in order to meet the high peak rate requirements of the service, subsequent versions need to introduce multiple carriers in the direct communication interface. This will cause the following problem: the protocol versions supported by different terminals for direct communication may be different. For example, the sending terminal supports SL CA, but its corresponding receiving terminal does not support SL CA. Therefore, it is necessary to consider how to assist the terminal or the network equipment serving the terminal to determine whether to use carrier aggregation and / or whether to allow the data of a bearer to be transmitted through multiple carriers when allocating direct communication interface resources for the terminal.

[0173] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0174] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or apparatus.

[0175] In the embodiments of the present disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship. In the embodiments of the present disclosure, the term "plurality" refers to two or more, and other quantifiers are similar.

[0176] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0177] The relevant concepts mentioned in this disclosure are briefly described below.

[0178] Traditional wireless communications use cellular network communications, where terminals and network devices transmit uplink and downlink data / control information via the Uu interface.

[0179] Direct communication allows nearby terminals to transmit data over a short distance using a direct communication link (also called a Sidelink, PC5 link, sidelink, or bypass, SL for short). The wireless interface corresponding to Sidelink is called a direct communication interface (also called a Sidelink interface, PC5 interface, sidelink interface, or bypass interface).

[0180] Different terminals performing direct communication may support different protocol versions. For example, if a transmitting terminal supports SL CA, its corresponding receiving terminal may or may not support SL CA. Even if both the transmitting and receiving terminals support SL CA, the SL CA modes they support may differ. Therefore, it is necessary to consider how to assist the terminal or the network equipment serving the terminal in determining whether to use carrier aggregation and / or whether to allow the transmission of data from a bearer across multiple carriers when allocating direct communication interface resources to the terminal.

[0181] Referring to FIG. 1 , FIG. 1 is a structural diagram of a network system applicable to an embodiment of the present disclosure. As shown in FIG. 1 , the network system includes a user terminal 11 and a base station 12. The user terminal 11 may be a user equipment (UE), such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), or a wearable device. It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present disclosure. The base station 12 may be a fifth generation (5G) or later base station (e.g., the next generation Node B (gNB), a 5G New Radio Node B (NR Node B)), or a base station in other communication systems or a gateway supporting satellite communication, also referred to as a Node B. It should be noted that in the embodiment of the present disclosure, only a 5G base station is used as an example, but the specific type of the base station 12 is not limited.

[0182] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The information acquisition and transmission methods, apparatuses, terminals, and network devices provided in the embodiments of the present disclosure can be applied to wireless communication systems. The wireless communication system can be a system that uses fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will appreciate that the 5G NR system is only an example and not a limitation.

[0183] The embodiments of the present disclosure provide an information acquisition and transmission method, apparatus, terminal, and network device, so as to assist a terminal or a network device serving a terminal in determining whether to use carrier aggregation and / or whether to allow data of one carrier to be transmitted through multiple carriers when allocating direct communication interface resources to the terminal.

[0184] Among them, the method and the device are based on the same application 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.

[0185] As shown in FIG2 , an embodiment of the present disclosure provides an information acquisition method, which is executed by a first terminal. The method includes:

[0186] Step S201, obtaining target indication information;

[0187] It should be noted that the target indication information is used to indicate whether to use direct communication interface carrier aggregation and / or the carrier aggregation transmission mode of the direct communication interface. The target indication information can be understood as indicating direct communication interface carrier aggregation related information.

[0188] It should be noted that the embodiment of the present disclosure can assist the terminal or the network equipment serving the terminal in determining whether to use carrier aggregation when allocating direct communication interface resources to the terminal and / or whether to allow the data of one bearer to be transmitted through multiple carriers by obtaining information related to direct communication interface carrier aggregation.

[0189] In some embodiments, the first terminal referred to in the embodiments of the present disclosure refers to a direct communication sending terminal.

[0190] In some embodiments, in one implementation, the specific implementation of obtaining the target indication information includes one of the following:

[0191] A11. Receive transmission configuration information from a higher layer of the first terminal, where the transmission configuration information carries first indication information, where the first indication information is the target indication information;

[0192] In some embodiments, the higher layer may be, for example, a vehicle-to-everything (V2X) layer, a proximity services (ProSe) layer, or a direct communication interface signaling (PC5-S) layer. The transmission configuration information is configured based on a direct communication interface target layer 2 address (L2 ID).

[0193] That is, in this case, the target indication information is obtained from the transmission configuration information sent by the upper layer of the first terminal. Generally speaking, the first indication information is used to indicate the relevant information of the direct communication interface carrier aggregation of the first terminal itself.

[0194] In some embodiments, in one implementation, the first indication information includes at least one of the following:

[0195] A111: Whether the first terminal uses direct communication interface carrier aggregation (SL CA) when performing data transmission for the first target object;

[0196] In some embodiments, the first target object includes: an L2 ID or a service identifier or a Quality of Service (QoS) profile; in some embodiments, the L2 ID may be a target L2 ID of the direct communication interface or a combination of a source L2 ID and a target L2 ID of the direct communication interface.

[0197] It should be noted that this situation can be understood as the first indication information being used to indicate the capability of the first terminal to perform direct communication interface carrier aggregation when performing data transmission. It may use direct communication interface carrier aggregation or not.

[0198] In some embodiments, in one implementation, whether to use direct communication interface carrier aggregation is indicated by at least one of the following:

[0199] A1111, indicated by 1 bit;

[0200] For example, a bit value of 0 indicates that SL CA is not used, and a bit value of 1 indicates that SL CA is used; or a bit value of 1 indicates that SL CA is not used, and a bit value of 0 indicates that SL CA is used.

[0201] A1112, indicating by band combination;

[0202] For example, if at least one bandcombination includes two or more carriers or bandwidth parts (Bandwidth Part, BWP), it indicates that SL CA is used; otherwise, it indicates that SL CA is not used.

[0203] A112, a carrier aggregation transmission mode of a direct communication interface used by the first terminal when performing data transmission for the first target object;

[0204] It should be noted that this situation can be understood as the first indication information being used to indicate the capability of the carrier aggregation transmission mode of the direct communication interface when the first terminal performs data transmission. In some embodiments, in one implementation, the carrier aggregation transmission mode includes at least one of the following:

[0205] A1121. A first target object can only be transmitted on one target resource;

[0206] In some embodiments, the target resource includes: a carrier or a BWP.

[0207] It should be noted that in this case, it can be understood that when the first terminal transmits data for the first target object, a first target object can only be transmitted on one target resource. For example, the data corresponding to an L2ID can only be transmitted on one carrier; for example, the data corresponding to a service identifier can only be transmitted on one BWP; for example, the data corresponding to a QoS profile can only be transmitted on one carrier.

[0208] In some embodiments, in this case, the first indication information may further include: a target resource corresponding to the first target object. Typically, the target resource may be identified by a specific frequency point, a resource number, or a resource index.

[0209] A1122. A first target object allows transmission on multiple target resources.

[0210] It should be noted that in this case, it can be understood that when the first terminal transmits data for the first target object, the data corresponding to a first target object can be transmitted on multiple (two or more) target resources, for example, the data corresponding to an L2 ID can be transmitted on two carriers; for example, the data corresponding to a service identifier can be transmitted on three BWPs; for example, the data corresponding to a QoS profile can be transmitted on two carriers.

[0211] A12. Receive terminal capability information from the second terminal, where the terminal capability information carries second indication information, and the second indication information is the target indication information;

[0212] That is, in this case, the target indication information is obtained from the terminal capability information sent by the second terminal. Generally speaking, the second indication information is used to indicate the relevant information of the direct communication interface carrier aggregation of the second terminal.

[0213] In some embodiments, in one implementation, the second indication information includes at least one of the following:

[0214] A121: Whether the terminal capability of the second terminal supports direct communication interface carrier aggregation;

[0215] It should be noted here that the second terminal is a direct communication peer of the first terminal.

[0216] It should be noted that this situation can be understood as the second indication information being used to indicate whether the second terminal supports the capability of direct communication interface carrier aggregation when performing data transmission. It may support direct communication interface carrier aggregation or may not support direct communication interface carrier aggregation; that is, the second terminal can support direct communication interface carrier aggregation, which can be understood as the terminal capability of the second terminal supporting direct communication interface carrier aggregation, and the second terminal may not support direct communication interface carrier aggregation, which can be understood as the terminal capability of the second terminal not supporting direct communication interface carrier aggregation.

[0217] In some embodiments, in one implementation, whether direct communication interface carrier aggregation is supported is indicated by at least one of the following:

[0218] A1211, indicated by 1 bit;

[0219] For example, a bit value of 0 indicates that SL CA is not supported, and a bit value of 1 indicates that SL CA is supported; or a bit value of 1 indicates that SL CA is not supported, and a bit value of 0 indicates that SL CA is supported.

[0220] A1212, indicated by frequency band combination;

[0221] For example, if at least one bandcombination includes two or more carriers or BWPs, it indicates that SL CA is supported; otherwise, it indicates that SL CA is not supported.

[0222] A122. A carrier aggregation transmission mode of the direct communication interface supported by the terminal capability of the second terminal;

[0223] It should be noted that this situation can be understood as the second indication information being used to indicate the capability of the carrier aggregation transmission mode of the direct communication interface when the second terminal performs data transmission. That is, the second indication information refers to which carrier aggregation transmission mode is supported by the terminal capability of the second terminal.

[0224] In some embodiments, in one implementation, the carrier aggregation transmission mode includes at least one of the following:

[0225] A1221. A second target object can only be transmitted on one target resource;

[0226] In some embodiments, the second target object includes: a direct communication interface logical channel or an L2 ID or a quality of service attribute or a service identifier; and the target resource includes: a carrier or a BWP.

[0227] It should be noted that in this case, it can be understood that the terminal capability of the second terminal only supports that a second target object can only be transmitted on one target resource, for example, an L2 ID can only be transmitted on one carrier; for example, a service identifier can only be transmitted on one BWP; for example, a QoS profile can only be transmitted on one carrier; for example, a direct communication interface logical channel can only be transmitted on one BWP.

[0228] In some embodiments, in one implementation, the second indication information may further include: a target resource corresponding to the second target object. Typically, the target resource is identified by a resource number or a resource index.

[0229] A1222, a second target object allows transmission on multiple target resources;

[0230] It should be noted that in this case, it can be understood that the terminal capability of the second terminal supports that the data corresponding to a second target object can be transmitted on multiple (two or more) target resources, for example, the data corresponding to an L2 ID can be transmitted on two carriers; for example, the data corresponding to a service identifier can be transmitted on three BWPs; for example, the data corresponding to a QoS profile can be transmitted on two carriers; for example, the data corresponding to a direct communication interface logical channel can be transmitted on three BWPs.

[0231] In some embodiments, if the target indication information indicates that the first target object does not use direct communication interface carrier aggregation, the target indication information is further used to indicate the target resources used by the control information and / or direct communication interface data corresponding to the first target object of the direct communication interface;

[0232] The target resource includes: a carrier or a bandwidth portion.

[0233] It should be noted that the control information corresponding to the first target object of the direct communication interface may be direct communication interface signaling (PC5-Signaling, PC5-S) or direct communication interface radio resource control (Radio Resource Control, RRC) (PC5-RRC) signaling. The data corresponding to the first target object of the direct communication interface may be service data to be transmitted by the first target object.

[0234] This situation can be understood as, if the terminal does not use (that is, the first terminal does not use, or the second terminal's capabilities do not support) direct communication interface carrier aggregation, it is necessary to determine the carrier or bandwidth part for transmitting the control information and / or direct communication interface data corresponding to the first target object of the direct communication interface to ensure accurate allocation of direct communication interface resources.

[0235] That is to say, in some embodiments, if the above-mentioned A11 is used to obtain the target indication information, the first indication information carried in the transmission configuration information should also indicate to the first terminal the target resources used by the control information and / or direct communication interface data corresponding to the first target object of the direct communication interface, that is, the first indication information also needs to include: a first indication of the target resources used by the control information and / or direct communication interface data corresponding to the first target object of the direct communication interface, for example, the first indication is used to indicate the carrier or bandwidth portion used by the control information corresponding to the direct communication interface L2 ID, service identifier or service quality attribute; or, the first indication is used to indicate the carrier or bandwidth portion used by the direct communication interface data corresponding to the direct communication interface L2 ID, service identifier or service quality attribute.

[0236] In some embodiments, if the above-mentioned A12 is used to obtain the target indication information, the second indication information carried in the terminal capability information should also indicate to the first terminal the target resources used for the control information corresponding to the first target object of the direct communication interface and / or the data corresponding to the first target object of the direct communication interface, that is, the second indication information also needs to include: a second indication of the target resources used for the control information corresponding to the first target object of the direct communication interface and / or the data corresponding to the first target object of the direct communication interface.

[0237] It should be noted that direct communication interface resource allocation includes two modes:

[0238] Mode 1, namely, network scheduling resource allocation, requires the network device to allocate resources to the terminal;

[0239] Mode 2, namely terminal-selected resource allocation, requires the terminal to select resources on its own.

[0240] In some embodiments, in one case, after the direct communication interface sending terminal obtains the target indication information, if in Mode 1, the direct communication sending terminal needs to send third indication information to the network device, and the third indication information is used to instruct the network device to select direct communication interface resources for the first terminal.

[0241] In some embodiments, the third indication information may be determined based on the first indication information or the second indication information.

[0242] In some embodiments, in one implementation, the third indication information includes at least one of the following:

[0243] B11, direct communication interface target L2 ID;

[0244] B12. a carrier aggregation transmission mode of the direct communication interface of the first terminal;

[0245] It should be noted that the carrier aggregation transmission mode includes the above-mentioned A1121 and / or A1122.

[0246] B13. Indication information indicating whether the direct communication interface of the first terminal uses direct communication interface carrier aggregation;

[0247] In some embodiments, the indication information of whether to use direct communication interface carrier aggregation can be indicated by on (ON) or off (OFF) information. For example, when the indication is on, it means that the direct communication interface of the first terminal uses direct communication interface carrier aggregation; when the indication is off, it means that the direct communication interface of the first terminal does not use direct communication interface carrier aggregation.

[0248] B14. a carrier aggregation transmission mode corresponding to the first target object of the direct communication interface of the first terminal;

[0249] It should be noted that the carrier aggregation transmission mode includes the above-mentioned A1121 and / or A1122.

[0250] B15. Terminal capability information of the second terminal;

[0251] In some embodiments, the terminal capability information of the second terminal includes the above-mentioned A121 and / or A122.

[0252] In some embodiments, the terminal may report the third indication information to the network device via a Uu interface message (such as direct communication link terminal information (SidelinkUEInformation)).

[0253] It should be further explained that, because the information transmission mode of the direct communication sending terminal includes: Unicast (UC), Group Cast (GC), and / or Broadcast (BC), when the direct communication sending terminal performs unicast communication, it can clearly know the communication peer. Generally, in order for the communication peer to accurately receive data sent by the direct communication sending terminal, the direct communication peer needs to send its own terminal capability information to the direct communication sending terminal. In this case, the direct communication sending terminal obtains the second indication information sent by the direct communication sending terminal. Therefore, the third indication information sent by the direct communication sending terminal to the network device generally includes B11 and / or B15. When the direct communication sending terminal performs multicast or broadcast communication, because there may be multiple direct communication peers, the direct communication sending terminal generally obtains the transmission configuration information of its own high-layer transmission. In this case, the direct communication sending terminal obtains the first indication information. Therefore, the third indication information sent by the direct communication sending terminal to the network device generally includes at least one item from B11 to B14.

[0254] In some embodiments, in one case, after the direct communication interface sending terminal obtains the target indication information, if in Mode 2, the direct communication sending terminal needs to perform direct communication interface resource selection according to the transmission configuration information or the terminal capability information.

[0255] It should be further explained that when a direct communication sending terminal performs unicast communication, it can clearly know the identity of the communication peer. Typically, in order for the communication peer to accurately receive data sent by the direct communication sending terminal, the direct communication peer needs to send its own terminal capability information to the direct communication sending terminal. In this case, the direct communication sending terminal obtains the second indication information sent by the direct communication peer. Therefore, the direct communication sending terminal allocates direct communication interface resources based on the second indication information. When a direct communication sending terminal performs multicast or broadcast communication, because there may be multiple direct communication peers, the direct communication sending terminal typically obtains transmission configuration information for its own high-layer transmission. In this case, the direct communication sending terminal obtains the first indication information. Therefore, the direct communication sending terminal allocates direct communication interface resources based on the first indication information.

[0256] In some embodiments, whether the network device performs direct communication interface resource selection or the direct communication sending terminal performs direct communication interface resource selection, if a specific target object is allowed to be transmitted on multiple target resources, one or more carriers or BWPs are selected for the specific target object, and specific transmission resources are selected on each carrier or BWP as the transmission resources of the specific target object.

[0257] In some embodiments, in one implementation, selecting multiple carriers or BWPs for a specific target object includes:

[0258] Select multiple carriers or BWPs for a specific target object based on the following principles:

[0259] C11, mapping relationship between services configured at high level and carriers or BWP;

[0260] C12. The correspondence between business and target objects;

[0261] C13, carrier or BWP status;

[0262] In some embodiments, the status may be, for example, a channel busy ratio (CBR) or a channel quality.

[0263] For example, when selecting based on C13, multiple carriers or BWPs with lower channel occupancy or better channel quality may be preferentially selected. For example, when selecting based on C11 and C12, it is necessary to first determine the mapping relationship between the target object and the carrier or BWP based on C11 and C12, and then select multiple carriers or BWPs for the specific target object based on the mapping relationship. For example, when selecting based on C11-C13, it is necessary to first determine the mapping relationship between the target object and the carrier or BWP based on C11 and C12, and then preliminarily select a carrier or BWP for the specific target object based on the mapping relationship, and then, among the preliminarily selected carriers or BWPs, prioritize multiple carriers or BWPs with lower channel occupancy or better channel quality.

[0264] The specific implementation of the embodiment of the present disclosure is described below with examples.

[0265] Application Scenario 1: SL unicast, using Mode 1 resource allocation

[0266] Assume that UE2 is a direct communication sending terminal and UE1 is the communication peer of UE2, as shown in Figure 3. The specific implementation process includes:

[0267] Step 31: UE1 sends the terminal capability information of its direct communication interface to UE2.

[0268] After UE1 and UE2 successfully establish a unicast connection, UE1 may send terminal capability information of its direct communication interface to UE2. The terminal capability information needs to carry second indication information, where the second indication information includes: whether UE1's terminal capability supports direct communication interface carrier aggregation and / or the carrier aggregation transmission mode of the direct communication interface supported by the terminal capability.

[0269] Whether direct communication interface carrier aggregation is supported may be indicated in one of the following ways:

[0270] Indicated by 1 bit; a bit value of 0 indicates that SL CA is not supported, and a bit value of 1 indicates that SL CA is supported.

[0271] Indicated by Bandcombination: if at least one bandcombination contains two or more carriers / BWPs, SL CA is supported; otherwise, SL CA is not supported.

[0272] The carrier aggregation transmission mode includes at least one of the following:

[0273] A second target object can only be transmitted on one carrier or BWP;

[0274] One secondary object allows transmission on multiple carriers or BWPs.

[0275] The second target object may be a direct communication interface logical channel, an L2 ID, a quality of service attribute, or a service identifier.

[0276] Step 32: UE2 reports third indication information to the network device. The third indication information includes: terminal capability information of UE1. The terminal capability information is used to indicate the direct communication interface capability.

[0277] UE2 may report the third indication information to the network device through a Uu interface message, and specifically may report it through SidelinkUEInformation, or may introduce a new RRC message for reporting.

[0278] Step 33: The network device determines the SL CA policy when UE2 sends data to UE1 via the direct communication interface. The SL CA policy includes whether to use SL CA and / or SL CA transmission mode.

[0279] Step 34: The network device sends direct communication interface resource allocation mode configuration information to UE2;

[0280] The resource allocation mode configuration information may be carried via a Uu interface RRC reconfiguration message.

[0281] Step 35: UE2 sends a Scheduling Request (SR) or a Buffer Status Report (BSR) of the direct communication interface to the network device.

[0282] It should be noted that the purpose of UE2 sending SR or BSR is to request direct communication interface resources from the network device.

[0283] Step 36: The network device allocates direct communication interface resources to UE2;

[0284] The network device allocates direct communication interface resources to UE2 according to the SL CA policy determined in step 33 .

[0285] It should be noted that if the network device determines that SL CA needs to be used for a target object of the direct communication interface and the SL CA mode is that a target object can be transmitted on multiple carriers or BWPs, then when the network device performs resource selection, it can select multiple carriers or BWPs for the specific target object and select specific transmission resources on each carrier or BWP respectively.

[0286] Furthermore, the principles to be considered when selecting multiple carriers or BWPs for the specific target object include at least one of the following:

[0287] The mapping relationship between high-level configured services and carriers or BWPs;

[0288] The correspondence between business and target objects;

[0289] The status of the carrier or BWP, for example, the status includes CBR or channel quality.

[0290] Application Scenario 2: SL multicast or SL broadcast, using Mode 1 resource allocation

[0291] Assume that UE2 is a direct communication transmitting terminal. For direct communication interface multicast or broadcast, UE2 may correspond to one or more receiving terminals. As shown in FIG4 , the specific implementation process includes:

[0292] Step 41: UE2 obtains transmission configuration information from a higher layer of UE2.

[0293] The transmission configuration information may be, but is not limited to, a Tx Profile. For example, UE2 obtains the transmission configuration information from the V2X layer, ProSe layer, or PC5-S layer of UE2. In some embodiments, the transmission configuration information is configured based on a direct communication interface target L2 ID.

[0294] The transmission configuration information needs to carry first indication information, wherein the first indication information includes whether UE2 uses direct communication interface carrier aggregation when performing data transmission for the first target object, and / or the carrier aggregation transmission mode of the direct communication interface used by UE2 when performing data transmission for the first target object.

[0295] Whether to use direct communication interface carrier aggregation may be indicated in one of the following ways:

[0296] It can be indicated by 1 bit; if the bit value is 0, it means SL CA is not used, and if the bit value is 1, it means SL CA is used.

[0297] Indicated by Bandcombination: if at least one bandcombination contains two or more carriers / BWPs, SL CA is used; otherwise, SL CA is not used.

[0298] The carrier aggregation transmission mode includes at least one of the following:

[0299] A first target object can only be transmitted on one carrier or BWP;

[0300] One first target object allows transmission on multiple carriers or BWPs.

[0301] The first target object may be an L2 ID, a service identifier, or a quality of service attribute.

[0302] If the carrier aggregation transmission mode is such that a first target object can only be transmitted on one carrier or BWP, then in some embodiments, the first indication information also needs to carry the target resource corresponding to the first target object.

[0303] Step 42: UE2 sends third indication information to the network device;

[0304] In some embodiments, UE2 reports third indication information to the network device through a Uu interface message (such as a SidelinkUEInformation message), where the third indication information includes at least one of the following:

[0305] Direct communication interface target L2 ID;

[0306] Carrier aggregation transmission mode of the direct communication interface of UE2;

[0307] Indication information of whether the direct communication interface of UE2 uses direct communication interface carrier aggregation;

[0308] a carrier aggregation transmission mode corresponding to the first target object of the direct communication interface of UE2;

[0309] Step 43: The network device determines the SL CA policy when UE2 sends data on the direct communication interface. The SL CA policy includes whether to use SL CA and / or SL CA transmission mode for each target L2 ID or each bearer or logical channel under the target L2 ID.

[0310] Step 44: The network device sends direct communication interface resource allocation mode configuration information to UE2;

[0311] The resource allocation mode configuration information may be carried by a Uu interface RRC Reconfiguration message.

[0312] Step 45: UE2 sends an SR or SL BSR to the network device.

[0313] It should be noted that the purpose of UE1 sending the SR or SL BSR is to request direct communication interface resources from the network device.

[0314] Step 46: The network device allocates direct communication interface resources to UE2;

[0315] The network device allocates direct communication interface resources to UE2 according to the SL CA policy determined in step 43 .

[0316] It should be noted that if the network device determines that SL CA needs to be used for a target object of the direct communication interface and the SL CA mode is that a target object can be transmitted on multiple carriers or BWPs, then when the network device performs resource selection, it can select multiple carriers or BWPs for the specific target object and select specific transmission resources on each carrier or BWP respectively.

[0317] Furthermore, the principles to be considered when selecting multiple carriers or BWPs for the specific target object include at least one of the following:

[0318] The mapping relationship between high-level configured services and carriers or BWPs;

[0319] The correspondence between business and target objects;

[0320] The status of the carrier or BWP, for example, the status includes CBR or channel quality.

[0321] Application scenario 3: SL unicast, using Mode 2 resource allocation

[0322] Assuming that UE2 is a direct communication sending terminal and UE1 is the communication peer of UE2, as shown in FIG5 , the specific implementation process includes:

[0323] Step 51: UE1 sends the terminal capability information of its direct communication interface to UE2.

[0324] After UE1 and UE2 successfully establish a unicast connection, UE1 may send terminal capability information of its direct communication interface to UE2. The terminal capability information needs to carry second indication information, where the second indication information includes: whether UE1's terminal capability supports direct communication interface carrier aggregation and / or the carrier aggregation transmission mode of the direct communication interface supported by the terminal capability.

[0325] Whether direct communication interface carrier aggregation is supported may be indicated in one of the following ways:

[0326] Indicated by 1 bit; if the bit value is 0, it means SL CA is not supported, and if the bit value is 1, it means SL CA is supported.

[0327] Indicated by Bandcombination: if at least one bandcombination contains two or more carriers / BWPs, SL CA is supported; otherwise, SL CA is not supported.

[0328] The carrier aggregation transmission mode includes at least one of the following:

[0329] A second target object can only be transmitted on one carrier or BWP;

[0330] One secondary object allows transmission on multiple carriers or BWPs.

[0331] The second target object may be a direct communication interface logical channel, an L2 ID, a quality of service attribute, or a service identifier.

[0332] Step 52: UE2 determines whether to use SL CA and / or SL CA transmission mode for a specific target object based on the second indication information when sending data to UE1 via the direct communication interface;

[0333] Step 53: SL CA resource allocation;

[0334] It should be noted that if UE2 determines that SL CA resource allocation is required for a target object and the SL CA mode is that a target object can be transmitted on multiple carriers or BWPs, then when UE2 performs resource selection, it can select multiple carriers or BWPs for the specific target object and select specific transmission resources on each carrier or BWP respectively.

[0335] Furthermore, the principles to be considered when selecting multiple carriers or BWPs for the specific target object include at least one of the following:

[0336] The mapping relationship between high-level configured services and carriers or BWPs;

[0337] The correspondence between business and target objects;

[0338] The status of the carrier or BWP, for example, the status includes CBR or channel quality.

[0339] It should be noted that, after resource allocation is completed, UE2 can perform data transmission in the SL CA manner.

[0340] Application Scenario 4: SL multicast or SL broadcast, using Mode 2 resource allocation

[0341] Assuming that UE2 is a direct communication transmitting terminal, for direct communication interface multicast or broadcast, UE2 may correspond to one or more receiving terminals, as shown in FIG6 . The specific implementation process includes:

[0342] Step 61: UE2 obtains transmission configuration information from a higher layer of UE2.

[0343] The transmission configuration information may be, but is not limited to, a Tx Profile. For example, UE2 obtains the transmission configuration information from the V2X layer, ProSe layer, or PC5-S layer of UE2. In some embodiments, the transmission configuration information is configured based on a direct communication interface target L2 ID.

[0344] The transmission configuration information needs to carry first indication information, wherein the first indication information includes whether UE2 uses direct communication interface carrier aggregation when performing data transmission for the first target object, and / or the carrier aggregation transmission mode of the direct communication interface used by UE2 when performing data transmission for the first target object.

[0345] Whether to use direct communication interface carrier aggregation may be indicated in one of the following ways:

[0346] It can be indicated by 1 bit; if the bit value is 0, it means SL CA is not used, and if the bit value is 1, it means SL CA is used.

[0347] Indicated by Bandcombination: if at least one bandcombination contains two or more carriers / BWPs, SL CA is used; otherwise, SL CA is not used.

[0348] The carrier aggregation transmission mode includes at least one of the following:

[0349] A first target object can only be transmitted on one carrier or BWP;

[0350] One first target object allows transmission on multiple carriers or BWPs.

[0351] The first target object may be an L2 ID, a service identifier, or a quality of service attribute.

[0352] If the carrier aggregation transmission mode specifies that a first target object can only be transmitted on one carrier or BWP, in some embodiments, the first indication information also needs to carry the target resource corresponding to the first target object. Step 62: UE2 determines whether to use SL CA and / or SL CA transmission mode for a specific target object based on the first indication information when sending data on the direct communication interface.

[0353] Step 63: SL CA resource allocation;

[0354] It should be noted that if UE2 determines that SL CA resource allocation is required for a target object and the SL CA mode is that a target object can be transmitted on multiple carriers or BWPs, then when UE2 performs resource selection, it can select multiple carriers or BWPs for the specific target object and select specific transmission resources on each carrier or BWP respectively.

[0355] Furthermore, the principles to be considered when selecting multiple carriers or BWPs for the specific target object include at least one of the following:

[0356] The mapping relationship between high-level configured services and carriers or BWPs;

[0357] The correspondence between business and target objects;

[0358] The status of the carrier or BWP, for example, the status includes CBR or channel quality.

[0359] Step 64: After resource allocation is completed, UE2 can perform data transmission in the SL CA manner.

[0360] It should be noted that the embodiments of the present disclosure can assist the resource allocation node in determining whether to use SL CA and / or the specific SL CA transmission mode for the target object of the direct communication interface, so as to ensure that the communication counterpart can receive in the same manner, thereby improving data transmission reliability.
