Resource scheduling method, terminal and network equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a resource scheduling method, a terminal and network equipment.

Background

With the continuous development of mobile communication technology, various innovative applications, such as mobile broadband, multimedia, Machine Type Communication (MTC), industrial control, Intelligent Transportation System (ITS), etc., will become the main use cases in the 5G era. Many applications relate to direct link (sidelink) communication, and more typically, for example, Vehicle-to-Vehicle (abbreviated V2X) services, including Vehicle-to-Vehicle (abbreviated V2V), Vehicle-to-Infrastructure (abbreviated V2I), Vehicle-to-Network (abbreviated V2N) and Vehicle-to-pedestrian (abbreviated V2P) communication, etc., to improve the reliability of information interaction between vehicles.

At present, in R15V 2X defined by 3GPP, repeated transmission of a Packet Data Convergence Protocol (PDCP) data Packet is introduced, that is, a terminal copies two data packets in the same PDCP entity, and sends out the two data packets at different transmission carrier frequencies through two logical channels, and a receiving end receives the two data packets at different carrier frequencies to improve the reliability of data transmission of a direct link. Wherein, the two logical channels for data packet repeat transmission need to transmit PDCP data packets at different carrier frequencies to obtain frequency diversity gain at the receiving end. In a scenario where a base station schedules resources for a terminal, since the terminal is responsible for establishing and maintaining a logical channel for direct link communication in a direct link and the base station does not sense the logical channel existing in the terminal, the base station cannot perform corresponding configuration for a single logical channel, and at this time, how the base station obtains data amount of the logical channel corresponding to different scheduling carrier frequencies existing on the terminal side to perform resource scheduling becomes a key.

Detailed Description

The embodiments of the present invention will be described below with reference to the drawings.

It should be understood that the technical solution of the present application can be specifically applied to various communication systems, for example: global system for mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), time division-synchronous code division multiple access (TD-SCDMA), universal mobile telecommunications system (universal mobile telecommunications system, UMTS), Long Term Evolution (LTE), etc. with the continuous development of communication technology, the solution of the present application can also be used in future networks, such as 5G networks, also known as new air interfaces or New Radio (NR) networks, or in D2D (device) networks, M2 (2M) networks, etc.

The network device related to the present application may refer to an entity used for sending or receiving information on a network side, for example, the entity may be a base station, or may be a Transmission Point (TP), a Transmission and Reception Point (TRP), a relay device, a radio network controller in a Cloud Radio Access Network (CRAN), an access point, or an access network device in a Public Land Mobile Network (PLMN) for future evolution, or other network devices having a function of a base station, and the present application is not limited.

In this application, a terminal is a device with communication capabilities that may include a handheld device with wireless communication capabilities, an in-vehicle device, a wearable device, a computing device or other processing device connected to a wireless modem, or the like. Terminals can be called different names in different networks, for example: mobile terminal, User Equipment (UE), mobile station, subscriber unit, station, cellular telephone, personal digital assistant, wireless modem, wireless communication device, handheld device, laptop, cordless telephone, wireless local loop station, access terminal, subscriber station, mobile station, remote terminal, user agent, user device, vehicle or infrastructure, and the like. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal device in the internet of things, a virtual reality device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN, etc., which may communicate with one or more core networks via a radio access network (e.g., RAN).

In this application, a base station may also be referred to as a base station device, which is a device deployed in a radio access network to provide wireless communication functions. The names of the base stations may be different in different radio access systems, for example, the base station is called node B (NodeB) in a UMTS network, the base station is called evolved node B (evolved NodeB) in an LTE network, and the base station is called a Transmission Reception Point (TRP) network node or G node B (G-NodeB, gNB) in a future 5G system, or may also be called a small station, a micro station, and so on, which are not listed herein.

Referring to fig. 1, fig. 1 is a block diagram of a communication system according to an embodiment of the present invention. Specifically, as shown in fig. 1, the communication system may include a network device and a terminal, and the terminal and the network device may perform communication using the communication system described above, for example, the terminal may obtain a scheduling resource from the network device to perform transmission of a V2X message between terminals based on the resource, that is, implement V2X communication.

Specifically, V2X communication generally includes two communication scenarios, namely a direct link communication scenario and a communication scenario in which a message is relayed through a network device such as a base station. For example, as shown in fig. 2a, the direct link communication refers to that a terminal, such as vehicles, directly communicates with each other, that is, a link for implementing direct communication between vehicles is called a direct link (Sidelink, abbreviated as SL), also called a side link, where resources for communication between vehicles are configured or preconfigured from a base station. For another example, as shown in fig. 2b, relaying the message through the base station means that the data that the vehicle needs to transmit needs to be forwarded through the base station, the vehicle transmits the data to the base station through an uplink between the vehicle and the base station, and the base station transmits the data to another vehicle through a downlink between the vehicle and another vehicle.

In the direct link, communication between terminals such as vehicles can be divided into a plurality of modes including a base station scheduling mode and a mode in which the terminal autonomously selects resources. As shown in fig. 3a, the base station scheduling mode is that the vehicle terminal sends a request to the base station, and the base station dynamically or semi-dynamically schedules a Resource (or "scheduled direct link Resource") for direct link communication of the terminal according to the request, such as a Dedicated Resource (Dedicated Resource) or other resources, and can send information of the Resource to the terminal, such as sending the information of the Resource through a Dedicated Signaling (Dedicated Signaling), such as a Dedicated Radio Resource Control Signaling (Dedicated RRC), a Physical transmission Channel, such as a Physical Downlink Control Channel (PDCCH), or other signals. In the base station scheduling mode, the terminal may be in an RRC CONNECTED (RRC _ CONNECTED) state. As shown in fig. 3b, the mode of autonomous Resource selection by the terminal refers to that the base station configures at least one Resource Pool (Resource Pool) for the terminal through a System Information Block (SIB) message, such as an SIB21 and/or an SIB22 message, or dedicated signaling or other messages, and the terminal autonomously selects resources from the at least one Resource Pool for communication, or acquires resources from the at least one preconfigured Resource Pool for communication. Each resource pool comprises a plurality of time-frequency resources which can be used for direct link communication. Wherein SIB and dedicated RRC signaling are collectively referred to as RRC signaling. In the mode in which the terminal autonomously selects resources, the terminal may be in an RRC IDLE state (RRC _ IDLE) or an RRC CONNECTED state (RRC _ CONNECTED). The pre-configuration may refer to that the terminal is pre-configured inside the terminal when the terminal is shipped from a factory, or that the terminal is pre-configured by a network side, such as a network device, and is stored inside. The terminal selects the resource may be randomly selecting a resource in the resource pool, or selecting a resource from the resource pool based on the listening reservation mechanism, such as selecting a free resource for V2X communication by listening whether a resource in the resource pool is free.

For the scenario that the network device schedules resources for the terminal, in the base station scheduling mode, the base station is responsible for scheduling the resources for the terminal to perform the direct link communication. Therefore, the base station needs to know the data amount of the logical channels corresponding to different scheduling carrier frequencies existing in the terminal, so as to perform resource scheduling according to the data amount of the logical channels of different scheduling carrier frequencies, and ensure that when the terminal performs repeated transmission of data packets, the same data packet can be copied into two parts and then transmitted through the two logical channels at different transmission carrier frequencies. It should be understood that the data retransmission referred to in the present application may also refer to the retransmission of more than two copies of data, that is, after one data packet is copied into multiple copies, the data packet is respectively transmitted through multiple logical channels at different transmission carrier frequencies, the number of copies of the data packet may be the same as the number of logical channels, and the two copies may correspond to each other. The present application describes an example in which the same data packet is duplicated into two data packets and then transmitted through two logical channels using different transmission carrier frequencies.

In this application, the carrier frequency may refer to a carrier frequency, or may also be referred to as a frequency band, a frequency, a spectrum, and the like, and this application is not limited thereto.

The application discloses a resource scheduling method, a terminal and network equipment, which are beneficial to realizing the resource scheduling of the terminal by the network equipment. The details are described below.

Referring to fig. 4, fig. 4 is an interaction diagram of a resource scheduling method according to an embodiment of the present invention. Specifically, as shown in fig. 4, the resource scheduling method according to the embodiment of the present invention may include the following steps:

401. the network equipment sends configuration information to the terminal, wherein the configuration information comprises a first carrier frequency set and a second carrier frequency set.

402. And the terminal respectively determines carrier frequency sets for data transmission for the first logic channel and the second logic channel according to the configuration information.

The network device may determine information of a carrier frequency set allocated for the terminal, generate configuration information indicating the carrier frequency set, such as a first carrier frequency set and a second carrier frequency set, and send the configuration information to the terminal. The terminal can receive configuration information from the network device to acquire a carrier frequency set, namely a first carrier frequency set and a second carrier frequency set, allocated to the terminal by the network device. After the first carrier frequency set and the second carrier frequency set are obtained, the terminal may respectively correspond (associate, bind) the first carrier frequency set and the second carrier frequency set with a first logical channel and a second logical channel of the terminal, that is, respectively determine carrier frequency sets for data transmission for the first logical channel and the second logical channel.

For example, the terminal determines that the set of carrier frequencies used for data transmission corresponding to the first logical channel is the first set of carrier frequencies, and determines that the set of carrier frequencies used for data transmission corresponding to the second logical channel is the second set of carrier frequencies, which indicates that the terminal can use the transmission resources in the first set of carrier frequencies to transmit the data in the first logical channel, and the terminal can use the transmission resources in the second set of carrier frequencies to transmit the data in the second logical channel. For another example, the terminal determines that the set of carrier frequencies used for data transmission corresponding to the first logical channel is the second set of carrier frequencies, and determines that the set of carrier frequencies used for data transmission corresponding to the second logical channel is the first set of carrier frequencies, which indicates that the terminal can use the transmission resources in the second set of carrier frequencies to transmit the data in the first logical channel, and the terminal can use the transmission resources in the first set of carrier frequencies to transmit the data in the second logical channel.

The first carrier frequency set comprises at least one transmission carrier frequency, and the second carrier frequency set comprises at least one transmission carrier frequency. Optionally, the configuration information may indicate different transmission carrier frequencies through different carrier frequency identifiers.

Optionally, the first set of carrier frequencies is orthogonal to the second set of carrier frequencies, i.e. there are no common elements in both sets.

Optionally, the transmission resource in the first carrier frequency set may be a time-frequency resource on any transmission carrier frequency in the first carrier frequency set.

Optionally, the transmission resource in the second carrier frequency set may be a time-frequency resource on any transmission carrier frequency in the second carrier frequency set.

The configuration information may be carried in an SIB message, dedicated RRC signaling, a physical transport channel, or other messages, which is not limited in this application.

403. The terminal determines a first identifier according to the attribute information of the data to be transmitted.

Optionally, the attribute information may include at least one of reliability information, delay information, communication distance information, data rate information, data priority information, and data traffic type information. Where the attribute information may be an identification, index, or other information that points to the attribute. It is to be understood that the attribute information may also be the attribute itself. Taking reliability information as an example, the reliability information may be at least one of a reliability identifier, a reliability index, a reliability range, and a reliability enumeration value. Other similarities are not described herein.

Alternatively, the data may be a packet.

Wherein the reliability information can be used to indicate the reliability corresponding to the data. The data on the terminal may have different reliabilities. The corresponding reliability of the data embodies the transmission reliability requirements/levels/constraints of the data. The reliability may be, but is not limited to, end-to-end transmission reliability, air interface transmission reliability, and the like. For example, the transmission reliability may be defined as a 1-bit error rate, i.e., a 1-bit error rate; 1-symbol error rate, i.e. 1-symbol error rate; or 1-packet error ratio, i.e., 1-packet error rate, etc.

The delay information may be used to indicate a delay corresponding to the data. The data at the terminal may have different delay requirements/constraints, and the delay may be, but is not limited to, end-to-end transmission delay, air interface delay, delay budget, transmission time interval, and the like.

The communication distance information may be used to indicate a communication distance or a communication range corresponding to the data. The data on the terminal may have different communication distances or communication ranges.

The data rate information may be used to indicate a transmission rate corresponding to the data. The data on the terminal may have different transmission rates. Alternatively, the transmission rate may be a modulation and coding scheme, and the data on the terminal may have different modulation and coding schemes.

The terminal may have a plurality of different types of services, and different service type information may be used to indicate the different types of services. Illustratively, the traffic types may be distinguished by different application layer identifications (AID), or, at the access layer, different traffic types may be distinguished by different Destination address identifications (Destination layer2 ID). Optionally, a mapping relationship exists between the destination address identifier and the application layer identifier.

Wherein different data may have different data priorities. Generally, different priority data have different transmission parameters in the access stratum, and transmission of high priority data is preferentially guaranteed.

Alternatively, the attribute information of the data may be transferred from an upper layer (above the access stratum) to the access stratum together with the data in the form of a primitive.

The terminal may pre-store mapping relationships (corresponding relationships) between the attribute information of different data and different identifiers, where the mapping relationships include a one-to-one mapping relationship (i.e., one set of attribute information corresponds to one identifier), a one-to-many mapping relationship (i.e., one set of attribute information corresponds to multiple identifiers), and a many-to-one mapping relationship (i.e., multiple sets of attribute information correspond to one identifier). And when data needs to be transmitted, the attribute information of the data, namely the data to be transmitted, can be acquired, and one or more identifiers corresponding to the attribute information of the data are determined according to the mapping relation between the attribute information of different data and different identifiers. The determined identity comprises at least a first identity. Optionally, the mapping relationship may be pre-configured, or may be sent to the terminal by the network device.

The data to be transmitted may refer to data in a PDCP entity or data in a logical channel.

It should be noted that, the present application does not limit the execution sequence of step 402 and step 403. Illustratively, the terminal may perform 402 and then 403; or executing 403 first and then executing 402; or steps 402, 403 are performed simultaneously. 404. And the terminal sends a resource scheduling request to the network equipment, wherein the resource scheduling request comprises the first identifier and the first data volume.

The resource scheduling request may be used to request the network device to schedule a direct link resource for the terminal. The first data amount includes at least a data amount of the first logical channel.

Optionally, the resource scheduling request may further include a second data amount, where the second data amount includes at least the data amount of the second logical channel. Therefore, the terminal can report the data volume of different logical channels corresponding to different carrier frequencies to the network equipment.

Alternatively, the scheduling resource request may be a Buffer Status Report (BSR). It may be included in an uplink Protocol Data Unit (PDU) sent by the terminal to the network device.

If the uplink resource is insufficient, and the resource scheduling request, such as a buffer status report, may have a truncated format, the resource scheduling request may include only the first identifier and the first data amount, so that the network device performs resource scheduling in time according to the first identifier and the first data amount.

Further optionally, the first data amount may further include data amounts of other logical channels than the first logical channel, and/or the second data amount may further include data amounts of other logical channels than the second logical channel.

For example, it is assumed that a single PDCP entity delivers duplicated data to two logical channels when data retransmission is performed, but there may be more than two logical channels since a terminal may have multiple PDCP entities simultaneously requiring data retransmission. For example, assuming that a third logical channel and a fourth logical channel are also performing data repeat transmission, where the terminal determines that the carrier frequency set used for data transmission corresponding to the third logical channel is the first carrier frequency set, and determines that the carrier frequency set used for data transmission corresponding to the fourth logical channel is the second carrier frequency set, at this time, the first data amount reported by the terminal may include a sum of data amounts of the first logical channel and the third logical channel, and the second data amount may include a sum of data amounts of the second logical channel and the fourth logical channel.

Optionally, the single logical channel is associated with a service type, and the first data amount and/or the second data amount comprises only a sum of data amounts of one or more logical channels having the same service type (e.g. the same destination address identifier or the same application layer identifier).

Optionally, the single PDCP entity delivers the duplicated data to two logical channels, respectively, which means that the duplicated data is delivered to two RLC entities, where the two RLC entities correspond to the two logical channels one to one.

Alternatively, the amount of data may be, but is not limited to, an index, an identification of the amount of data, or the amount of data itself.

Alternatively, the data amount may be a data amount of a buffer corresponding to the logical channel, for example, the first data amount may be a data amount of a buffer corresponding to the first logical channel, and the second data amount may be a data amount of a buffer corresponding to the second logical channel. Further optionally, the data amount of the buffer may be a data amount of a PDCP entity buffer and/or a Radio Link Control protocol (RLC) entity buffer.

405. And the network equipment determines the attribute information of the data corresponding to the first identifier according to the preset mapping relation between different identifiers and the attribute information of different data, and schedules the direct link resource for the terminal according to the attribute information of the data and the first data volume.

The network device may pre-store the attribute information of different data and the mapping relations of different identifiers, where the corresponding relations include one-to-one mapping relation, one-to-many mapping relation, and many-to-one mapping relation. Generally, the mapping is network device configured. Optionally, the mapping relationship may be sent to the terminal through RRC signaling. Optionally, the mapping relationship may be explicit or implicit.

For example, the identifier is a Logical Channel Group identifier (LCGID for short), and the reliability information is a reliability identifier.

In one possible implementation, the mapping relationship may be explicitly indicated. The mapping information generated by the network device may include at least one LCGID and at least one reliability identifier, for example, the mapping information includes LCGID1, reliability identifier 1, LCGID2, and reliability identifier 2, where LCGID1 corresponds to reliability identifier 1, and LCGID2 corresponds to reliability identifier 2, and the network device may send the mapping information to the terminal. After receiving the mapping information, the terminal can determine that the LCGID1 has a corresponding relationship with the reliability identifier 1 and the LCGID2 has a corresponding relationship with the reliability identifier 2 through the mapping information.

In another possible implementation, the mapping relationship may be implicitly indicated. The mapping information may not include the LCGID, but only include at least one reliability information, but the terminal may determine the LCGID corresponding to the at least one reliability information according to a predetermined sequence or rule. Wherein the sequence may be protocol specified or agreed upon by the network device and the terminal. For example, since the LCGIDs may be a number, two parties may agree that the LCGIDs are arranged in order from small to large. For example, if the LCGID numbers are 0, 1, 2, and 3 in sequence, the mapping information may include only at least one reliability information without including the LCGID. The terminal may determine the logical channel group identifier corresponding to the at least one reliability information according to the order of the at least one reliability information.

For example, the mapping information only includes { reliability identifier 1}, { reliability identifier 2, reliability identifier 3}, { reliability identifier 4}, { reliability identifier 5, reliability identifier 6 }. The LCGIDs are arranged in the order from small to large, after the terminal receives the mapping information, the terminal can determine that { reliability identifier 1} corresponds to the logical channel group identifier with the number 0, { reliability identifier 2, reliability identifier 3} corresponds to the logical channel group identifier with the number 1, { reliability identifier 4}, and { reliability identifier 5, reliability identifier 6} correspond to the logical channel group identifiers with the

numbers

2 and 3, respectively.

For another example, the mapping information includes { reliability flag 1}, { reliability flag 2, reliability flag 3}, and { reliability flag 4 }. Meanwhile, the mapping information further includes { data priority identifier 1}, { data priority identifier 2}, and { data priority identifier 2}, so that it can be understood that the two parties agree that LCGIDs are arranged in a descending order, after the terminal receives the mapping information, it can be determined that { reliability identifier 1 and data priority identifier 1} correspond to a logical channel group identifier with a number of 0, { reliability identifier 2 and data priority identifier 2}, { reliability identifier 3 and data priority identifier 2} correspond to a logical channel group identifier with a number of 1, and { reliability identifier 4 and data priority identifier 2} correspond to a logical channel group identifier with a number of 2.

For another example, the mapping information includes { reliability identifier 1, data priority identifier 1}, { reliability identifier 2, and data priority identifier 1}, and it can be understood at this time that the two parties agree that LCGIDs are arranged in order from small to large, and after the terminal receives the mapping information, it may be determined that { reliability identifier 1 and data priority identifier 1} correspond to a logical channel group identifier numbered 0, and { reliability identifier 2 and data priority identifier 1} correspond to a logical channel group identifier numbered 1.

It should be noted that the attribute information corresponding to the data may include multiple items of reliability information, delay information, communication distance information, data rate information, data priority information, and data service type information, and the mapping information configured by the network device may only refer to at least one item of attribute information corresponding to the data, and does not necessarily include all items of data attributes.

For example, the attribute information of the data may include reliability information and data priority information, and the mapping information may include only mapping relationships between different identifiers and data priority information.

Optionally, the mapping may be pre-configured. The network device may receive a resource scheduling request from the terminal, and further determine attribute information corresponding to the first identifier, such as reliability information, delay information, communication distance information, data rate information, data priority information, data service type information, and the like, according to a mapping relationship between the different identifiers and attribute information of different data, so that the network device may schedule a resource, such as a direct link resource, for the terminal according to data attribute information corresponding to the first identifier, that is, attribute information of data to be transmitted, and a first data volume carried by the resource scheduling request.

Further optionally, the resource scheduling request may also carry a second data amount. In some optional embodiments, the identifier determined by the terminal according to the attribute information of the data to be transmitted may only include a first identifier, that is, a identifier is determined, the resource scheduling request may carry the first identifier, and an order of the first data amount and the second data amount in the resource scheduling request is the same as an order of the first carrier frequency set and the second carrier frequency set in the configuration information. Therefore, the network device can determine the first carrier frequency set and the second carrier frequency set according to the sequence of the first data volume and the second data volume in the resource scheduling request, where the sequence of the first data volume and the second data volume in the resource scheduling request is the same as the sequence of the first carrier frequency set and the second carrier frequency set in the configuration information, that is, the corresponding carrier frequency set is determined according to the sequence (position) of different data volumes in the resource scheduling request, and further, the direct link resource can be scheduled for the terminal according to the first carrier frequency set, the second carrier frequency set, the first data volume, the second data volume, and the attribute information of the data.

For example, the network device configures the mapping relationship: { reliability identification 1}, and { reliability identification 2 }. It is understood that they correspond to LCGID0 and LCGID1, respectively. Meanwhile, the network device configures { a first carrier frequency set } { a second carrier frequency set }, and then when the reliability identifier corresponding to the data to be transmitted is 2, the terminal determines that the first identifier is LCGID1, and if the terminal corresponds the first logical channel to the first carrier frequency set and the second logical channel to the second carrier frequency set, the resource scheduling request sent by the terminal to the network device includes LCGID1, the first data volume, and the second data volume.

Otherwise, if the terminal associates the first logical channel with the second carrier frequency set and associates the second logical channel with the first carrier frequency set, the resource scheduling request sent by the terminal to the network device includes the LCGID1, the second data volume, and the first data volume.

In some optional embodiments, the terminal may further determine the second identifier according to a mapping relationship between the different identifier and the attribute information of the different data and the attribute information of the data. That is to say, the terminal determines, according to the mapping relationship between the different identifiers and the attribute information of the different data, that the identifier corresponding to the attribute information of the data to be transmitted includes the first identifier and the second identifier. The first identifier and the second identifier may be carried in the resource scheduling request. Optionally, the determined identifier may correspond to a logical channel according to a preset rule, for example, the first identifier corresponds to the first logical channel, and the second identifier corresponds to the second logical channel. For example, the less numbered identifiers correspond to the less numbered logical channels (logical channel identifiers), or vice versa.

Or, optionally, the determined identifier may correspond to the carrier frequency set (the correspondence may be explicit or implicit) according to a preset rule (order or position), for example, the first identifier corresponds to the first carrier frequency set, and the second identifier corresponds to the second carrier frequency set. Since the terminal determines the carrier frequency sets for data transmission for the first logical channel and the second logical channel, the terminal determines the first identifier and the second identifier corresponding to the first logical channel and the second logical channel, respectively. It can be understood that, at this time, the resource scheduling request may only include the first identifier and the first data amount, so that the network device performs resource scheduling for the terminal according to the first identifier and the first data amount, or, at this time, the resource scheduling request includes the first identifier, the first data amount, the second identifier, and the second data amount, so that the network device performs resource scheduling for the terminal according to the first identifier, the first data amount, the second identifier, and the second data amount.

For example, the network device configures the mapping relationship: { reliability identification 1, data priority identification 1}, { reliability identification 2, data priority identification 2}, { reliability identification 1, data priority identification 1 }. It is understood that they correspond to LCGID0, LCGID1, and LCGID2, respectively. Assuming that the reliability identifier 1 and the data priority identifier 1 of the data to be transmitted, the terminal determines LCGIDs 0 and LCGIDs 2 as optional identifiers. Further, the network device may configure { the first carrier frequency set } { the second carrier frequency set }, and may agree according to a preset rule (order or location) such as a protocol, where the same two items in the mapping relationship sequentially correspond to the two sets configured by the network device in order, and then the terminal may determine that the LCGID0 corresponds to the first carrier frequency set, and the LCGID2 corresponds to the second carrier frequency set. Assuming that the terminal corresponds the first logical channel to the first carrier frequency set and the second logical channel to the second carrier frequency set, the terminal determines that the LCGID0 corresponds to the first logical channel and the LCGID2 corresponds to the second logical channel, and the resource scheduling request sent by the terminal to the network device includes the LCGID0, the first data volume, or the LCGID2, the second data volume, or both the LCGID0, the first data volume, the LCGID2, and the second data volume.

On the contrary, if the terminal associates the first logical channel with the second carrier frequency set and the second logical channel with the first carrier frequency set, the terminal determines that the LCGID0 corresponds to the second logical channel and the LCGID2 corresponds to the first logical channel, and the resource scheduling request sent by the terminal to the network device includes the LCGID2, the first data volume, or includes the LCGID2, the first data volume, the LCGID0, and the second data volume at the same time.

In some optional embodiments, the terminal may determine the first identifier and the second identifier according to the attribute information of the data to be transmitted, the mapping relationship between the different identifiers and the different carrier frequency sets, and specifically may determine the first identifier and the second identifier according to the mapping relationship between the different identifiers and the attribute information of the different data and the mapping relationship between the different identifiers and the different carrier frequency sets, for example, determine that the first identifier corresponds to the first logical channel, and the second identifier corresponds to the second logical channel. Therefore, the network device can respectively determine the first carrier frequency set corresponding to the first identifier according to the mapping relation between different identifiers and different carrier frequency sets, and then perform resource scheduling for the terminal according to the first carrier frequency set, the first identifier and the first data volume. Or, the network device may determine, according to the mapping relationships between different identifiers and different carrier frequency sets, the first carrier frequency set corresponding to the first identifier and the second carrier frequency set corresponding to the second identifier, respectively, and then schedule the direct link resource for the terminal according to the first carrier frequency set, the first identifier, the first data volume, the second carrier frequency set, the second identifier, the second data volume, and the data attribute of the data.

For example: the network equipment configures a mapping relation: { reliability identification 1, data priority identification 1}, { reliability identification 2, data priority identification 2}, { reliability identification 1, data priority identification 1 }. It is understood that they correspond to LCGID0, LCGID1, and LCGID2, respectively. Assuming that the reliability identifier 1 and the data priority identifier 1 of the data to be transmitted, the terminal determines LCGIDs 0 and LCGIDs 2 as optional identifiers. Further, the network device configures mapping relationships between different identifiers and different carrier frequency sets: LCGID0, { first set of carrier frequencies }, LCGID2, { second set of carrier frequencies }. Assuming that the terminal corresponds the first logical channel to the first carrier frequency set and the second logical channel to the second carrier frequency set, the terminal determines that LCGID0 corresponds to the first logical channel and LCGID2 corresponds to the second logical channel, and the resource scheduling request sent by the terminal to the network device includes LCGID0, the first data volume, or includes LCGID0, the first data volume, LCGID2, and the second data volume at the same time.

On the contrary, if the terminal associates the first logical channel with the second carrier frequency set and the second logical channel with the first carrier frequency set, the terminal determines that the LCGID0 corresponds to the second logical channel and the LCGID2 corresponds to the first logical channel, and the resource scheduling request sent by the terminal to the network device includes the LCGID0, the second data volume, or the LCGID2, the first data volume, or both the LCGID0, the second data volume, the LCGID2, and the first data volume.

Optionally, the mapping relationship between the different identifiers and the different carrier frequency sets may be sent by the network device to the terminal. Further optionally, the order of the first data amount and the second data amount in the resource scheduling request is the same as the order of the first carrier frequency set and the second carrier frequency set in the configuration information.

Optionally, the mapping relationship between the different identifiers and the different data attribute information may also be included in the configuration information.

Optionally, the mapping relationship between the different identifiers and the different carrier frequency sets may be included in the configuration information.

Optionally, the mapping relationship between the different identifiers and the different carrier frequency sets may be explicit or implicit.

Optionally, the mapping relationship between the different identifier and the different carrier frequency set may only include the different identifier, that is, the mapping relationship between the different identifier and the different carrier frequency set is indicated by the different identifier.

Optionally, the first identifier may be a group identifier of the first logical channel, such as a first LCGID. Further optionally, the second identifier may be a group identifier of the second logical channel, such as a second LCGID. Further optionally, the resource scheduling request may further include information of Destination (Destination) addresses corresponding to each identifier or each data volume, such as an index of the Destination address, where the Destination address index points to the Destination address identifier.

For example, the configuration information sent by the network device to the terminal includes carrier frequency sets { f1, f2} and { f3, f4}, and it is assumed that the terminal determines that logical channel 1 corresponds to carrier frequency { f1, f2}, and logical channel 2 corresponds to carrier frequency { f3, f4}, i.e., data in logical channel 1 is allowed to be transmitted on scheduling resources on f1 and/or f2, and data in logical channel 2 is allowed to be transmitted on scheduling resources on f3 and/or f 4. The terminal can send a resource scheduling request at least comprising a first identifier and a first data volume and/or a second identifier and a second data volume to the network equipment according to the attribute information of the data to be transmitted.

As shown in fig. 5, it is an example of a format of a resource scheduling request, the resource scheduling request includes N sets of information, each set of information includes an index (Destination index) of a Destination address, an identifier such as LCGID, and a data Size (Buffer Size). The network device is responsible for scheduling resources for the terminal, and if the network device schedules resources on carrier frequency f1 for the terminal according to the resource scheduling request, the terminal is allowed to transmit data in logical channel 1 using carrier frequency f 1. If the network device schedules resources on carrier f2 for the terminal according to the resource scheduling request, the terminal is allowed to transmit data in logical channel 1 using carrier f 2.

It should be noted that in a single scheduling, the network device schedules the resource on carrier frequency f1, and does not mean that the data in logical channel 1 is necessarily transmitted. Since the terminal may have multiple logical channels, the multiple logical channels may all use the resource on f1 for transmission, the multiple logical channels may have different priorities, and since the total amount of scheduling resources is fixed, the amount of data that can be transmitted in each logical channel may be determined according to the priorities until the scheduling resources are exhausted. At this point it may be difficult for a portion of the low priority logical channels to get an opportunity to transmit data in their logical channels.

In the embodiment of the present invention, the network device may determine the carrier frequency by sending configuration information including the first carrier frequency set and the second carrier frequency set to the terminal, enabling the terminal to determine a set of carrier frequencies for data transmission for the first logical channel and the second logical channel respectively according to the configuration information, when data transmission is needed, the terminal can determine the first identifier according to the attribute information of the data to be transmitted, and transmits a resource scheduling request including the first identification and the first data amount to the network device, so that the network device can determine the attribute information of the data corresponding to the first identifier according to the preset mapping relation between different identifiers and the attribute information of different data, and scheduling the direct link resource for the terminal according to the attribute information of the data and the first data volume, thereby being beneficial to realizing the resource scheduling of the network equipment to the terminal.

Referring to fig. 6, fig. 6 is an interaction diagram of another resource scheduling method according to an embodiment of the present invention. Specifically, as shown in fig. 6, the resource scheduling method according to the embodiment of the present invention may include the following steps:

601. the network equipment sends configuration information to the terminal, wherein the configuration information comprises a first carrier frequency set and a second carrier frequency set.

602. And the terminal respectively determines carrier frequency sets for data transmission for the first logic channel and the second logic channel according to the configuration information.

603. The network equipment sends first mapping information to the terminal, wherein the first mapping information is used for indicating the mapping relation between different identifications and attribute information of different data.

Optionally, the mapping relationship between the different identifiers and the attribute information of the different data may be completed through one RRC signaling, may also be completed through multiple RRC signaling, or may also be sent through other signaling, which is not limited in this application.

Optionally, the mapping relationship indicated by the first mapping information may be explicitly indicated or implicitly indicated, which may specifically refer to the relevant description of the embodiment shown in fig. 4, and is not described herein again.

Optionally, the mapping relationship between the identifier in the first mapping information and the data attribute information may be one-to-one, one-to-many, many-to-one, and the like, which is not limited in this application.

Optionally, the configuration information and the first mapping information may be included in the same RRC signaling.

It should be noted that, the present application does not limit the execution sequence of step 603 and step 601. For example, the network device may perform 601 first and then 603; or firstly 603 and then 601; or step 601 and step 603 are executed simultaneously.

604. And the terminal determines the first identifier and the second identifier according to the first mapping information and the attribute information of the data. The terminal can receive the first mapping information from the network equipment, and then determines the identifier corresponding to the attribute information of the data to be transmitted according to the mapping relation corresponding to the first mapping information. In this embodiment, the determined identifier includes a first identifier and a second identifier. For example, the terminal may determine the first identifier and the second identifier according to the first mapping information and the attribute information of the data, respectively, and correspond the first identifier to the first logical channel and the second identifier to the second logical channel. For another example, the terminal may determine the first identifier and the second identifier respectively according to the first mapping information, the attribute information of the data, and the corresponding relationship between the element in the first mapping information and the carrier frequency set agreed by the protocol, and correspond the first identifier to the first logical channel and the second identifier to the second logical channel. For another example, the terminal may further receive second mapping information from the network device, where the second mapping information is used to indicate a mapping relationship between different identifiers and different carrier frequency sets, and then the terminal may determine a first identifier and a second identifier according to the first mapping information, the second mapping information, and the attribute information of the data to be transmitted, and correspond the first identifier to the first logical channel, and the second identifier to the second logical channel. Reference may be made to the description of the embodiment shown in fig. 4, which is not repeated herein.

Optionally, the first identifier may be a group identifier of the first logical channel, such as an LCGID, and the second identifier may be a group identifier of the second logical channel, such as an LCGID.

Optionally, the mapping relationship indicated by the second mapping information may be explicitly indicated or implicitly indicated, and is similar to the first mapping information described above, and is not described herein again.

Optionally, the mapping relationship between the identifier in the second mapping information and the carrier frequency set may be one-to-one, one-to-many, many-to-one, and the like, which is not limited in this application.

Optionally, the configuration information, the first mapping information, and the second mapping information may be included in the same RRC signaling.

605. And the terminal sends a resource scheduling request to the network equipment, wherein the resource scheduling request comprises the first identifier, the second identifier, the first data volume and the second data volume.

The first data volume at least includes a data volume of the first logical channel, the second data volume at least includes a data volume of the second logical channel, and the resource scheduling request can be used to request the network device to schedule direct link resources for the terminal.

It should be understood that when the terminal sends the resource scheduling request, the resource scheduling request may include only the first identifier, the first data amount, or only the second identifier, the second data amount, or both the first identifier, the second identifier, the first data amount, and the second data amount. For example, when the uplink resource is not enough, the reporting may be truncated, that is, only part of the information may be reported, for example, only the first identifier and the first data amount are reported in the current resource scheduling request, and then the second identifier and the second data amount are reported in the next resource scheduling request. This embodiment takes the example that the resource scheduling request includes the first identifier, the second identifier, the first data amount, and the second data amount as an example.

606. The network equipment determines the attribute information of the data corresponding to the first identifier according to the preset mapping relationship between different identifiers and the attribute information of different data, and the network equipment determines the first carrier frequency set corresponding to the first identifier and the second carrier frequency set corresponding to the second identifier respectively according to the mapping relationship between different identifiers and different carrier frequency sets.

607. And the network equipment schedules the direct link resources for the terminal according to the first carrier frequency set, the second carrier frequency set, the first data volume, the second data volume and the attribute information of the data.

The network device may receive a resource scheduling request from the terminal, and further determine attribute information corresponding to the first identifier and/or the second identifier, such as reliability information, delay information, communication distance information, data rate information, data priority information, data service type information, and the like, according to a mapping relationship between the different identifiers and attribute information of different data; further, the network device may also determine, according to the mapping relationships between the different identifiers and the different carrier frequency sets, the carrier frequency sets corresponding to the first identifier and the second identifier, respectively, so that the network device may schedule resources, such as direct link resources, for the terminal according to the data attribute information corresponding to the first identifier, that is, the attribute information of the data to be transmitted, the first data amount and the second data amount of the logical channel corresponding to the different carrier frequencies, which are carried by the resource scheduling request, and the determined carrier frequency sets.

In the embodiment of the present invention, a network device may send configuration information including a first carrier frequency set and a second carrier frequency set to a terminal, so that the terminal may determine, according to the configuration information, carrier frequency sets for data transmission for a first logical channel and a second logical channel, respectively, and when data transmission is required, the terminal may determine a first identifier and a second identifier according to attribute information of data to be transmitted and various mapping information, and send a resource scheduling request including the first identifier, the second identifier, a first data volume, and a second data volume to the network device, so that the network device may determine attribute information of data corresponding to the first identifier according to preset mapping information, and schedule a direct link resource for the terminal according to the attribute information of the data, the first data volume, and the second data volume. That is to say, the terminal can distinguish the logical channels for data repeat transmission by reporting the first identifier and the second identifier, so that the network device can determine the data amount of the logical channels corresponding to different carrier frequencies, thereby facilitating the network device to schedule the resource of the terminal.

Referring to fig. 7, fig. 7 is an interaction diagram of another resource scheduling method according to an embodiment of the present invention. Specifically, as shown in fig. 7, the resource scheduling method according to the embodiment of the present invention may include the following steps:

701. the network equipment sends configuration information to the terminal, wherein the configuration information comprises a first carrier frequency set and a second carrier frequency set.

702. And the terminal respectively determines carrier frequency sets for data transmission for the first logic channel and the second logic channel according to the configuration information.

The steps 701-702 can refer to the description related to the steps 401-402 in the embodiment shown in fig. 4, which is not repeated herein.

703. The network equipment sends first mapping information to the terminal, wherein the first mapping information is used for indicating the mapping relation between different identifications and attribute information of different data.

Optionally, the mapping relationship indicated by the first mapping information may be explicitly indicated or implicitly indicated, which is not described herein.

It should be noted that, the present application does not limit the execution sequence of step 703 and step 701. For example, the network device may perform 701 first and then 703; or 703 is executed first and then 701 is executed; or step 701 and step 703 are executed simultaneously.

704. And the terminal determines the first identifier according to the first mapping information and the attribute information of the data.

The terminal can receive the first mapping information from the network equipment, and then determines the identifier corresponding to the attribute information of the data to be transmitted according to the mapping relation corresponding to the first mapping information. In this embodiment, the determined identifier includes only one identifier, i.e., the first identifier.

705. And the terminal sends a resource scheduling request to the network equipment, wherein the resource scheduling request comprises the first identifier, the first data volume and the second data volume.

The resource scheduling request is used for requesting the network device to schedule the direct link resource for the terminal. The first data amount includes at least a data amount of the first logical channel, and the second data amount includes at least a data amount of the second logical channel. In this embodiment, the order of the first data volume and the second data volume in the resource scheduling request may be the same as the order of the first carrier frequency set and the second carrier frequency set in the configuration information, so that the network device can distinguish the data volumes of the logical channels corresponding to different carrier frequencies.

Optionally, the first identifier may be a group identifier of the first logical channel, such as an LCGID.

706. And the network equipment determines the attribute information of the data corresponding to the first identifier according to the preset mapping relation between different identifiers and the attribute information of different data, and determines the first carrier frequency set and the second carrier frequency set according to the sequence of the first data volume and the second data volume in the resource scheduling request.

707. And the network equipment schedules the direct link resources for the terminal according to the first carrier frequency set, the second carrier frequency set, the first data volume, the second data volume and the attribute information of the data.

The network device may receive the resource scheduling request from the terminal, and further determine attribute information corresponding to the first identifier, such as reliability information, delay information, communication distance information, data rate information, data priority information, data service type information, and the like, according to a mapping relationship between the different identifiers and attribute information of different data. Further, the network device may also determine, according to an order of a first data volume and a second data volume in the resource scheduling request, a carrier frequency set corresponding to the first data volume and the second data volume, for example, if the first data volume is before and the second data volume is after in the resource scheduling request, and the first carrier frequency set is before and the second carrier frequency set is after in the configuration information, the network device may determine that the carrier frequency set corresponding to the first data volume is the first carrier frequency set and the carrier frequency set corresponding to the second data volume is the second carrier frequency set. Therefore, the network device can schedule resources, such as direct link resources, for the terminal according to the data attribute information corresponding to the first identifier, namely the attribute information of the data to be transmitted, the first data volume and the second data volume of the logical channel corresponding to different carrier frequencies carried by the resource scheduling request, and the determined carrier frequency set.

In the embodiment of the present invention, a network device may send configuration information including a first carrier frequency set and a second carrier frequency set to a terminal, so that the terminal may determine, according to the configuration information, carrier frequency sets for data transmission for a first logical channel and a second logical channel, respectively, and further when data transmission is required, the terminal may determine a first identifier according to attribute information of data to be transmitted and various mapping information, and send a resource scheduling request including the first identifier, a first data volume, and a second data volume to the network device, so that the network device may determine attribute information of data corresponding to the first identifier according to preset mapping information, and schedule a direct link resource for the terminal according to the attribute information of the data, the first data volume, and the second data volume. That is to say, the terminal can distinguish the logical channels for data repeat transmission according to the sequence of the first data volume and the second data volume in the resource scheduling request by reporting the first identifier, so that the network device can determine the data volumes of the logical channels corresponding to different carrier frequencies, thereby facilitating the network device to schedule the resource of the terminal.

Referring to fig. 8, fig. 8 is an interaction diagram of another resource scheduling method according to an embodiment of the present invention. Specifically, as shown in fig. 8, the resource scheduling method according to the embodiment of the present invention may include the following steps:

801. the network device generates resource scheduling information that includes a first resource and a first characteristic corresponding to the first resource.

802. The network device sends the resource scheduling information to the terminal.

In some embodiments, the network device may configure resources for the terminal through a System Information Block (SIB) or Dedicated Radio Resource Control (Dedicated Radio Resource Control), that is, send Resource scheduling Information; or, the network device may configure resources for the terminal through a Physical Downlink Control Channel (PDCCH); or, the network device may configure resources for the terminal through a media access control layer control element MAC control element (abbreviated as CE), and the like, which is not limited in this application.

Optionally, the scheduling resource, that is, the first resource, may be a resource that is dynamically or semi-statically scheduled by the network device for the terminal, or the resource scheduling information is sent to the terminal by the network device in a dynamic or semi-static manner.

Optionally, the terminal may send a resource scheduling request to the network device, and the network device sends the resource scheduling information to the terminal after receiving the resource scheduling request. Alternatively, optionally, the network device may actively send the resource scheduling information to the terminal, for example, dynamically or semi-statically send the resource scheduling information, that is, the network device may directly send the resource scheduling information to the terminal without the terminal sending a resource scheduling request to the network device.

Optionally, the resource scheduling information may be included in multiple RRC signaling, which is not limited in this application.

Optionally, the correspondence between the first resource and the first characteristic may be explicit or implicit.

803. The terminal encapsulates Data of at least one logical channel, which supports the first characteristic, into a Media Access control Protocol Data Unit (MAC PDU).

Wherein the logical channel supporting the first characteristic may mean that data in the logical channel may be carried on a resource having the first characteristic. The at least one logical channel supporting the first characteristic is a logical channel capable of using the first resource.

804. The terminal transmits the MAC PDU through the direct link using the first resource.

The terminal may receive resource scheduling information from the network device, and may further encapsulate data of the at least one logical channel supporting the first characteristic into a MAC PDU, which is transmitted through the direct link and using the first resource.

Optionally, the first characteristic includes at least one of: modulation coding mode Information, retransmission times Information, transmission power Information, access technology Information, direct link Control Information (SCI) format Information, version number Information, and the like.

Take the example that the first characteristic includes modulation coding mode information. The modulation and coding scheme information may be used to indicate modulation and coding schemes allowed or not allowed to be used on the first resource. Since the service included in part of the logical channels may have a high requirement on transmission reliability, in order to ensure the transmission reliability, the data in the logical channels may be required to be processed in a low modulation and coding manner. For example, if the Modulation coding scheme corresponding to logical channel 1 is Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), and the coding scheme corresponding to logical channel 2 is 16 Quadrature Amplitude Modulation (QAM), then if the Modulation coding scheme information points to 16QAM, then the logical channel supports the first characteristic, and can be carried on the scheduling resource, i.e. the first resource.

It can be understood that the first resource includes several time-frequency resources, which can be used for data transmission.

For another example, if the modulation coding scheme information indicates that 16QAM is not allowed to be used, it indicates that logical channel 2 does not support the first characteristic.

Optionally, the modulation and coding scheme information may be a modulation and coding scheme index, an indication (for example, whether to allow one or more modulation and coding schemes to be used), or other information pointing to the modulation and coding scheme, which is not limited in this application.

Optionally, for a certain modulation and coding scheme, whether to allow or not may be indicated by different values, for example, 1/True indicates permission, and 0/False indicates non-permission, or vice versa.

Optionally, the modulation and coding scheme information may also point to a group of modulation and coding schemes, for example, the modulation and coding scheme information may point to BSPK, QPSK, and 16QAM, and then the data in logical channel 1 and logical channel 2 may be carried by using the scheduling resource.

Wherein, the retransmission time information can be used to indicate the retransmission times of Hybrid Automatic Repeat Request (harq) allowed or not allowed to be used on the first resource.

Wherein the transmit power information may be used to indicate a maximum transmit power, a minimum transmit power, or a transmit power range allowed to be used on the first resource, or may be used to indicate a power not allowed to be used on the first resource.

Wherein the version number information may be used to point to one or more different 3GPP defined protocol versions. As the 3GPP protocol is continually evolving, there are many different versions. Different protocol versions may contain different characteristics or transmission technologies and different versions may be identified by a version number. Taking V2X as an example, the earliest version of 3GPP defined to support V2X features is R14 version, currently R15 version is being standardized, and there may be different versions of R16, R17, etc. in the future. Where version R14 is not supporting high order modulation (e.g., 64QAM) and version R15 supports high order modulation (e.g., 64 QAM). Therefore, when the version number information indicates the R15 version, if data in a certain logical channel does not support data transmission using high order modulation (64QAM), the data in the logical channel cannot be carried on the scheduling resource at this time.

Wherein the access technology information may be used to indicate different access technologies, e.g. where there are a plurality of different access technologies, e.g. GSM, CDMA, LTE, NR, etc., different access technology physical layers may employ completely different frame formats. Therefore, when the access technology information indicates a certain access technology, only the scheduled resource, i.e. the first resource, is allowed to be used for transmitting data supporting the logical channel corresponding to the access technology. For example, when the access technology information indicates LTE, only data of a logical channel supporting LTE is allowed to be transmitted using the first resource.

The SCI format information may be used to indicate direct link Control information included in a Physical direct link Control Channel (PSCCH), which is also referred to as a PSCCH transmission format, and the receiving end may obtain a time-frequency position and other transmission parameters of a direct link data packet according to the SCI information, so as to obtain a transmission data packet. For example, the SCI may include information such as the priority of the current data, the resource reservation period, the number of retransmissions, and the time-frequency location of the resource. The physical layer may define a variety of different SCI formats to meet various types of direct link scheduling or configuration requirements. For example, to support different transmission characteristics, different SCI formats may be defined. Illustratively, if Sidelink supports transmit diversity (Tx diversity), there must be a field (explicit or implicit) in the SCI format to indicate whether the Tx diversity is used for the current transmission. Further, the SCI format information may include Tx diversity related parameters, so that the receiving end can obtain the information and process the information accordingly. For another example, in order to support 64QAM, in the modulation coding scheme field of the SCI format, information indicating whether 64QAM is supported, such as an index indicating 64QAM, may be included, indicating that 64QAM is supported for the SCI format. It will be appreciated that for a field of the two SCI formats (e.g., both fields indicating modulation and coding schemes), the two SCI formats may be considered different SCI formats if the same value indicates different physical meanings. The first characteristic may be SCI format information, and only logical channels supporting the transmission format can utilize the first resource for data transmission.

It should be noted that, for a certain logical channel supporting the first characteristic, it does not mean that data in the logical channel can be transmitted by using the scheduling resource in each scheduling. Since the terminal may have a plurality of logical channels, which all support the first characteristic, the plurality of logical channels may have different priorities, and since the total amount of the scheduling resources is constant, a certain amount of data may be sequentially encapsulated into the MAC PDU according to the priorities until the scheduling resources are exhausted. At this time, part of the low priority logical channels may have difficulty getting an opportunity to perform data encapsulation, and there is no opportunity to utilize the scheduling resource to transmit data in the logical channel. Alternatively, the priority of the logical channel may be preconfigured.

Optionally, when the first characteristic includes multiple choices, the terminal may perform data transmission according to one of the multiple choices. For example, when the multiple choices are not simultaneously available, the terminal may autonomously determine one of them and then encapsulate logical channel data supporting the selected property into a MAC PDU. Taking the first characteristic including version number information as an example, assuming that the resource scheduling information includes the first characteristic of R14 or R15, assuming that R14 and R15 have different data formats, and both are not simultaneously available, it is obvious that only one of them is possible to be used by the terminal, and then the terminal can determine to use R14 or R15 by itself, for example, the terminal determines R14, and then the terminal encapsulates at least one logical channel data supporting R14 into a MAC PDU, and transmits the MAC PDU using the first resource.

Optionally, the first characteristic may also be a combination of modulation and coding scheme information, retransmission time information, transmission power information, access technology information, SCI format information, and version number information. Namely, a plurality of information in modulation coding mode information, retransmission frequency information, transmitting power information, access technology information, SCI format information and version number information are simultaneously embodied by a single information element. For example, the first characteristic may be modulation coding scheme information of R15, and the logical channel supporting the R15 modulation coding scheme allows the first resource to be used at this time.

In the embodiment of the invention, the network equipment sends the resource scheduling information used for indicating the scheduling resources of the terminal and the characteristics corresponding to the scheduling resources to the terminal, so that the terminal can encapsulate the data of at least one logic channel supporting the characteristics into the MAC PDU and send the MAC PDU through the direct link by using the scheduling resources, thereby being beneficial to realizing the resource scheduling of the network equipment to the terminal.
