Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and related device for configuring data transmission resources in an internet of vehicles.

Background

The internet of vehicles V2X (vehicle to X) is a key technology of an intelligent transportation system, is considered to be one of the fields with the most industrial potential and the most clear market demand in an internet of things system, has the characteristics of wide application space, large industrial potential and strong social benefit, and has important significance for promoting the innovative development of the automobile and information communication industry, constructing a new mode and new state of automobile and traffic service, promoting the innovation and application of the automatic driving technology and improving the traffic efficiency and the safety level. The internet of vehicles generally refers to a communication Network that provides Vehicle information through sensors, in-Vehicle terminals, and the like mounted on a Vehicle, and realizes mutual communication between a Vehicle to Vehicle (V2V), a Vehicle to infrastructure (V2I), a Vehicle to Network (V2N), and a Vehicle to pedestrian (V2P).

Generally, in the V2X scenario, a wireless communication interface between the network device and the terminal device may be referred to as a Uu port, and based on the Uu port, a wireless communication link for performing Uplink communication between the terminal device and the network device may be referred to as an Uplink (UL); the wireless direct communication interface between the terminal device and other terminal devices may be referred to as a PC5 port, and based on the PC5 port, a communication link for performing direct communication between the terminal device and other terminal devices may be referred to as a Sidelink (SL). The Uu port can be a Uu port in a communication system such as an LTE system or an NR system; the PC5 port may be a PC5 port in a communication system such as an LTE system or an NR system.

Illustratively, a terminal device may be in communication connection with two radio access network devices at the same time and may transmit and receive data, which may be referred to as a dual-connectivity (DC). One of the two radio access network devices may be responsible for exchanging radio resource control messages with the terminal device and for exchanging with a core network control plane entity, so that the radio access network device may be referred to as a Master Node (MN), and the other radio access network device may be referred to as a Secondary base Station (SN).

In the V2X scenario, the terminal device is typically a vehicular device and the network device may be a radio access network device, such as a base station. In the existing mechanism, when a plurality of sidelink services are simultaneously transmitted in the same terminal device, for example, when two sidelinks of different systems simultaneously need to transmit data, there is no good mechanism to solve the problem of transmission conflict generated thereby.

In the existing mechanism, a situation that multiple sidelink services are transmitted simultaneously exists in the same terminal device, for example, a situation when two sidelink of different systems need to transmit data simultaneously, for example, on one hand, when the radio frequency capability of the terminal device cannot simultaneously support frequency resources of sidelink of different systems configured for the terminal device by the same wireless access network device, a transmission collision problem will occur to the sidelink service of the terminal device, and on the other hand, when the radio frequency capability of the terminal device cannot support frequency resources of sidelink of different systems configured for the terminal device by different wireless access network devices, a transmission collision problem will also occur to the sidelink service of the terminal device.

In view of this, embodiments of the present application provide a communication method and related device, so as to solve a problem in the prior art that when data transmission is performed simultaneously on frequency resources of sidelink with different systems, a transmission conflict will occur in a terminal device.

The terminal device may also be a cellular phone, or a cordless phone, or a Session Initiation Protocol (SIP) phone, or a Wireless Local Loop (WLL) station, or a Personal Digital Assistant (PDA), or a handheld device with a wireless communication function, or a computing device or other processing device connected to a wireless modem, or a vehicle-mounted device, or a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), a vehicle device in a vehicle network, and the like, and the specific implementation form of the terminal device is not limited in this embodiment of the present application.

In this application, the network device refers to a device that can be used to communicate with a terminal device, and the network device may be a Base Transceiver Station (BTS) in a global system for mobile communications (GSM) system or a Code Division Multiple Access (CDMA) system, a base station (nodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, an evolved node b (eNB, or eNodeB) in an LTE system, a wireless controller in a cloud radio access network (cloud access network, CRAN) scenario, or a relay station, a nodeB, a wearable access point, or a vehicle-mounted device, and a network device in a future 5G network, such as an NR nodeB, a gbb, or a global network b, a control unit (CRAN), a distributed control unit (unit), DU) or network equipment in a PLMN network evolved in the future, and the specific implementation form of the network equipment in the embodiment of the present application is not limited.

The first system and the second system in the present application are two different systems of communication systems, for example, the first system may be a Long Term Evolution (LTE) mobile communication system, and the second system may be a fifth generation (5th generation, 5G) mobile communication system or a New Radio (NR) system; of course, the first standard system may be a fifth generation (5G) mobile communication system or a New Radio (NR) system, and the second standard system may be a Long Term Evolution (LTE) mobile communication system, which is not limited in this application. Illustratively, the difference between the first system and the second system at least includes: waveform parameters, a modulation mode, bandwidth configuration, a wireless frame configuration mode, a resource multiplexing mode and a coding mode.

In this application, the first radio access network device may be a network device of a first standard or a network device of a second standard, and the second radio access network device may be a network device of a first standard or a network device of a second standard.

For example, the UL or Uu port in this application may refer to the UL or Uu port of the communication system of the first standard or the second standard, respectively; the SL or PC5 port may also be referred to as the SL or PC5 port of the first-standard or second-standard communication system, respectively.

For example, the features or contents identified by broken lines in the drawings related to the embodiments of the present application can be understood as optional operations or optional structures of the embodiments.

For convenience of describing embodiments of the present application, for example, the first terminal device or the second terminal device in fig. 1 to 11 may be a vehicle device, and the first radio access network device or the second radio access network device may be a radio access network device (such as a base station).

For example, the method provided by the present application may be applied to a communication system as shown in fig. 1 or fig. 2, where the system operates to implement mutual communication between a terminal device and a terminal device, and the following two cases may be included:

in the first case: as shown in fig. 1, a first terminal device and a second terminal device communicate with each other through network device relay, and the first terminal device or the second terminal device wirelessly communicates with the network device through a Uu port.

UL can be divided into a first system UL and a second system UL according to different systems, and the first system UL and the second system UL can be distinguished by different configurations in any one or any several aspects: waveform parameters, a modulation mode, bandwidth configuration, a wireless frame configuration mode, a resource multiplexing mode or a coding mode. For example, the UL of the first system may be a UL of an LTE mobile communication system, the UL of the second system may be a UL of a 5G mobile communication system or a UL of an NR system, or the UL of the first system may be a UL of a 5G mobile communication system, and the UL of the second system may be a UL of an LTE mobile communication system.

In the second case: and the terminal equipment is in the coverage range of the network equipment or not in the coverage range of the network equipment, and direct communication is carried out between the terminal equipment and the terminal equipment. As shown in fig. 2, the first terminal device and the second terminal device perform direct communication through SL. For example, the SLs may be divided into a first system SL and a second system SL according to different systems, and the first system SL and the second system SL may be distinguished by different configurations in any one or any several aspects: waveform parameters, a modulation mode, bandwidth configuration, a wireless frame configuration mode, a resource multiplexing mode or a coding mode. For example, the first system SL may be an SL of an LTE mobile communication system, the second system SL may be an SL of a 5G mobile communication system or an SL of an NR system, or the first system SL may be an SL of a 5G mobile communication system, and the second system SL may be an SL of an LTE mobile communication system.

A wireless direct communication process between a first terminal device and a second terminal device may be controlled by a network device, for example, the terminal device is within a coverage area of the network device, the wireless direct communication process between the terminal device and the terminal device is controlled by the network device, and the first terminal device serving as a data sending end may send control information and/or data information to the second terminal device serving as a data receiving end on an SL transmission resource configured by the network device (for example, obtained by the terminal by reporting a report buffer status report BSR to a network side), which may be referred to as a third mode (mode 3);

for example, the network device configures a SL transmission Resource pool for the terminal device through a System Information Broadcast (SIB) message or a Dedicated Radio Resource Control (Dedicated RRC) signaling in a communication coverage of the network device, and the first terminal device serving as a data transmitting end may acquire a transmission Resource on the SL from the SL Resource pool to transmit Control Information and/or data Information to the second terminal device serving as a data receiving end; or, for example, the terminal device is outside the communication coverage of the network device, a first terminal device serving as a data sending end autonomously obtains a sidelink communication resource from a preconfigured terminal device SL transmission resource pool to send control information and/or data information to a second terminal device serving as a data receiving end, for example, the first terminal device obtains an appropriate transmission resource in the terminal device SL transmission resource pool by monitoring a busy-idle state of a channel by itself to perform data transmission, for example, send the control information and/or data information. Optionally, the device manufacturer may store the SL transmission resource pool of the terminal device in the first terminal device before the first terminal device leaves the factory, or the network device may obtain the SL transmission resource pool of the terminal device when the first terminal device accesses the network, where this mode may be a fourth mode (mode 4).

It should be understood that fig. 1 and 2 are only exemplary network architecture diagrams, and the network architecture further includes other network element devices or functional units, which are not limited in this application.

In this embodiment, a first standard SL and a second standard SL may refer to a wireless communication link between a first terminal device and a second terminal device, and a first standard UL and a second standard UL refer to a wireless communication link between a first terminal device and a network device, that is, four types of wireless communication links are defined, including: the system comprises a first system SL, a first system UL, a second system SL and a second system UL.

Illustratively, according to the difference between the radio frequency capability and the frequency resource of the first terminal device, if two types of wireless communication links among the four types of wireless communication links can simultaneously support the first terminal device to transmit data, illustratively, the first format SL and the second format SL can support the first terminal device to simultaneously transmit data, it may be defined that the first format SL and the second format SL are wireless communication links with no common link (chain); two frequency resource sets respectively used by two wireless communication links which do not share a chain are also not shared, or that the two frequency resource sets do not share a chain means that one frequency resource is arbitrarily taken from the two frequency resource sets respectively, and the arbitrarily taken two frequency resources can both simultaneously support the first terminal device to transmit data.

If two types of wireless communication links in the four types of wireless communication links cannot support the first terminal device to transmit data simultaneously, for example, the first system SL and the second system SL cannot support the first terminal device to transmit data simultaneously, it may be defined that the first system SL and the second system SL are common wireless communication links; the two frequency resource sets respectively used by the two wireless communication links sharing the chain are also sharing the chain, or the two frequency resource sets sharing the chain mean that one frequency resource is respectively taken out from the two frequency resource sets, and two taken out frequency resources cannot simultaneously support the two frequency resources of the first terminal device for data transmission.

The frequency resource of the wireless communication link in this application may be at least one Band, or may be at least one Component Carrier (CC), or may be at least one serving cell (serving cell), and the set of frequency resources in this application may be, for example, a Bandwidth Combination (BC), or a set of Component Carriers (CC), or a set of serving cells (serving cells), and each BC may include at least one bandwidth resource (Band).

For example, the simultaneous transmission in this application may refer to simultaneous transmission and may also refer to simultaneous reception. For example, the co-chain (chain) in this application may be a co-transmit chain or a co-rf transmit chain, and for example, the non-co-chain (chain) in this application may be a non-co-transmit chain or a non-co-rf transmit chain. The co-chain (chain) in this application may be, for example, a co-receive chain or a co-radio frequency receive chain, and the non-co-chain (chain) in this application may be, for example, a non-co-receive chain or a non-co-radio frequency receive chain.

For example, a bit string (bit string) in the present application may be at least one bit value, and the value of the bit may be "1" or "0", so the bit string may represent "1110001".

For example, the Radio Access network device may configure the terminal device through a broadcast signal, Radio Resource Control (RRC) signaling, a Media Access Control (MAC CE) Control Element, Downlink Control Information (DCI), and the like. In the present application, the bearer related to information interaction between base stations may be delivered through an X2 interface or an Xn interface or through inter-node (inter-node) RRC messages in RRC signaling.

Illustratively, the first radio access network device may be a Master base station (MN) in a Dual Connect (DC) communication architecture, the second radio access network device may be a Secondary base Station (SN) in the DC communication architecture, or the first radio access network device may be an SN in the DC case and the second radio access network device may be an MN in the DC case.

Illustratively, the communication method corresponding to fig. 3 includes:

operation 301: the first terminal device sends a first message to the first radio access network device.

In one possible design, the first message may include: a first set and first indication information. The first set is, for example, a set of frequency resources of a first standard SL supported by the first terminal device, and the first indication information includes information indicating whether the first set and at least one set of frequency resources of a second standard SL supported by the first terminal device can simultaneously support data transmission.

In one possible design, the first message may include: the first set and the first indication information, and at least one set of frequency resources of the second system SL supported by the first terminal device. The first set is, for example, a set of frequency resources of a first standard SL supported by the first terminal device, and the first indication information includes information indicating whether the first set and at least one set can simultaneously support data transmission.

For example, the set of frequency resources of the second standard SL supported by the at least one first terminal device may include M sets (M is a positive integer), which may be named as a first set, … …, and an mth set, respectively. Illustratively, the first indication information may be in the form of a bit string (bit string) having a bit length of M. For example, if the value of the first bit of the bit string is "1", it indicates that the first set and the first set of the sets of frequency resources of the second system SL supported by the at least one first terminal device can simultaneously support the first terminal device to transmit data, and so on, if the value of the mth bit of the bit string is "1", it indicates that the mth set of the sets of frequency resources of the second system SL supported by the first set and the at least one first terminal device can simultaneously support the first terminal device to transmit data.

Illustratively, M is 5, the bit string is in the form of "11010", then the bit string indicates that the first set and the first set can simultaneously support the first terminal device to transmit data, the first set and the second set can simultaneously support the first terminal device to transmit data, the first set and the third set cannot simultaneously support the first terminal device to transmit data, the first set and the fourth set can simultaneously support the first terminal device to transmit data, and the first set and the fifth set cannot simultaneously support the first terminal device to transmit data.

The first partial set comprises a first set, a second set and a fourth set; the second set of portions includes a third set and a fifth set.

For example, if M is 5, then when the bit string is "11111", the first indication information may include: the first set and at least one set of frequency resources of the second standard SL supported by the first terminal equipment can simultaneously support the first terminal equipment to transmit data.

For example, if M is 5, then when the bit string is "00000", the first indication information may include: the first set and at least one set of frequency resources of the second system SL supported by the first terminal device cannot simultaneously support the first terminal device to transmit data.

Optionally, the first message may include: the first set and the first indication information, and at least one set of frequency resources of the first system SL supported by the first terminal device and at least one indication information. The first set is, for example, a set of frequency resources of a first system SL supported by the first terminal device, where the first indication information includes information indicating whether the first set and at least one set of frequency resources of a second system SL supported by the first terminal device can simultaneously support data transmission.

Optionally, the first message may include: the first set and the first indication information, at least one set of frequency resources of the second system SL supported by the first terminal device, at least one set of frequency resources of the first system SL supported by the first terminal device, and at least one indication information.

Illustratively, the set of frequency resources of the first system SL supported by the at least one first terminal device may include N sets (N is a positive integer), which may be named as a second set, … …, and an N +1 set, respectively, exemplarily. For example, the at least one indication information may include N indication information, which may be named as second indication information, … …, N +1 indication information, where the second indication information includes information indicating whether the second set and at least one set of frequency resources of the second standard SL supported by the first terminal device can simultaneously support data transmission, and so on, and the N +1 indication information includes information indicating whether the N +1 set and at least one set of frequency resources of the second standard SL supported by the first terminal device can simultaneously support data transmission.

The second to N +1 th indication information may be in the form of a bit string having a bit length of M. For example, if the value of the first bit of the bit string of the second indication information is "1", it indicates that the first set of the second set and at least one set of frequency resources of the second system SL supported by the first terminal device can simultaneously support the first terminal device to transmit data, and so on, if the value of the mth bit of the bit string of the second indication information is "1", it indicates that the mth set of the second set and at least one set of frequency resources of the second system SL supported by the first terminal device can simultaneously support the first terminal device to transmit data.

It is to be understood that any one or any plurality of pieces of information included in the first message may also be carried in different messages and sent separately, which is not limited herein.

for example, the frequency resource information of the first-system sidelink configured for the first terminal device or the frequency resource information of the second-system sidelink configured for the first terminal device may be at least one index value, and the first terminal device may index, through the index value, at least one frequency resource or at least one frequency resource set supported by the first terminal device, which is reported by the first terminal device in operation 301;

for example, the frequency resource information of the first-system sidelink configured for the first terminal device or the frequency resource information of the second-system sidelink configured for the first terminal device may be at least one specific frequency resource or at least one specific combination of frequency resources, or an identification number set of at least one serving cell, or an upper-bound identification value and a lower-bound identification value of the identification number set of at least one serving cell.
