In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following content.

Figure 1 is a schematic diagram of a communication system applicable to the embodiment of the present application. The transmission resources of the vehicle-mounted terminals (vehicle-mounted terminal 121 and vehicle-mounted terminal 122) are allocated by the base station 110, and the vehicle-mounted terminals transmit data on the sidelink according to the resources allocated by the base station 110. Specifically, the base station 110 may allocate resources for a single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.

Figure 2 is a schematic diagram of another communication system applicable to the embodiment of the present application. The vehicle-mounted terminals (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) independently select transmission resources on the resources of the side link for data transmission. Optionally, the vehicle-mounted terminal can select transmission resources randomly or select transmission resources through listening.

It should be noted that device-to-device communication is a Sidelink (SL) transmission technology based on Device to Device (D2D), which is different from the traditional cellular system in which communication data is received or sent through the base station. The methods are different. The Internet of Vehicles system uses end-to-end direct communication, so it has higher spectrum efficiency and lower transmission delay. There are two transmission modes defined in 3GPP, which are recorded as: mode A (sidelink resource allocation mode A) and mode B (sidelink resource allocation mode B).

Mode A: The transmission resources of the terminal are allocated by the base station, and the terminal transmits data on the sidelink according to the resources allocated by the base station; the base station can allocate resources for a single transmission to the terminal, or can allocate semi-static transmission resources to the terminal. resource.

Mode B: The terminal selects a resource in the resource pool for data transmission.

Proximity-based Services (ProSe) involve device-to-device communication, mainly targeting public safety services. In ProSe, by configuring the position of the resource pool in the time domain, for example, the resource pool is discontinuous in the time domain, so that the UE can transmit/receive data discontinuously on the sidelink, thereby achieving the effect of power saving.

The Internet of Vehicles system is mainly studied for vehicle-to-vehicle communication scenarios, which are mainly oriented to relatively high-speed moving vehicle-to-vehicle and vehicle-to-human communication services. In V2X, since the vehicle system has continuous power supply, power efficiency is not the main issue, but the delay of data transmission is the main issue. Therefore, the system design requires the terminal equipment to transmit and receive continuously.

Wearable device (FeD2D) scenario has been studied on the scenario where wearable devices access the network through mobile phones. It is mainly oriented to low mobile speed and low power access scenarios.

In FeD2D, the base station can configure the Discontinuous Reception (DRX) parameters of the remote terminal through a relay terminal.

In some scenarios, a multi-carrier mechanism is introduced, which is mainly reflected in the fact that the UE can support data packet segmentation and transmit data packets through multiple carriers to improve the data transmission rate; data packet replication, copying the same data packet into two copies, through Two carriers are sent to improve transmission reliability; and multi-carrier reception enhancement at the receiving end. Specifically, for data packet replication: Sidelink communication supports sidelink packet replication and is executed at the UE's Packet Data Convergence Protocol (PDCP) layer. For sidelink packet replication for transmission, the PDCP Protocol Data Unit (PDU) is replicated at the PDCP entity. Duplicate PDCP PDUs of the same PDCP entity are submitted to two different Radio Link Control (RLC) entities and are respectively associated with two different sidelink logical channels. Duplicate PDCP PDUs for the same PDCP entity are only allowed to be transmitted on different sidelink carriers.

In New Radio-Vehicle to Everything (NR-V2X), autonomous driving is supported, which puts forward higher requirements for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

In the LTE-V2X system, the broadcast transmission method is supported, and in the NR-V2X system, unicast and multicast transmission methods are introduced.

Similar to the LTE V2X system, the NR V2X system can also define the above two resource authorization modes mode A/mode B. Resource acquisition is indicated through sidelink authorization, that is, the sidelink authorization indicates the corresponding physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) and physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) resources. Time and frequency position.

In addition to feedback-free, UE-initiated Hybrid Automatic Repeat reQuest (HARQ) retransmission, feedback-based HARQ retransmission is introduced in NR V2X, which is not limited to unicast communication, but also includes multicast communication.

In NR V2X, since the vehicle system has continuous power supply, power efficiency is not the main issue, but the delay of data transmission is the main issue. Therefore, the system design requires the terminal equipment to transmit and receive continuously.

In order to facilitate a better understanding of the embodiment of the present application, the time slot structure in NR-V2X will be described with reference to Figure 3.

(a) in Figure 3 represents the time slot structure that does not include the Physical Sidelink Feedback Channel (PSFCH) in the time slot; (b) in Figure 3 represents the time slot structure that includes the PSFCH.

As shown in (a) in Figure 3, the Physical Sidelink Control Channel (PSCCH) starts from the second sidelink symbol of the time slot in the time domain and occupies 2 or 3 orthogonal frequency divisions. Multiplexing (Orthogonal frequency-division multiplexing, OFDM) symbols can occupy {10,12 15,20,25} physical resource blocks (PRB) in the frequency domain. In order to reduce the complexity of the UE's blind detection of PSCCH, only one number of PSCCH symbols and one number of PRBs are allowed to be configured in a resource pool. In addition, because the sub-channel (sub-channel) is the minimum granularity of physical sidelink shared channel (PSSCH) resource allocation in NR-V2X, the number of PRBs occupied by PSCCH must be less than or equal to the number of PRBs in a sub-channel in the resource pool. The number of PRBs included to avoid additional restrictions on PSSCH resource selection or allocation. PSSCH also starts from the second sidelink symbol of the time slot in the time domain. The last time domain symbol in the time slot is the Guard Period (GP) symbol, and the remaining symbols are mapped to the PSSCH. The first siderow symbol in this time slot is a repetition of the second siderow symbol. Usually the receiving terminal uses the first siderow symbol as an automatic gain control (Automatic Gain Control, AGC) symbol. The symbol on this symbol The data is generally not used for data demodulation. PSSCH occupies P sub-channels in the frequency domain, and each sub-channel includes Q consecutive PRBs, where P and Q are positive integers.

As shown in (b) in Figure 3, when the time slot contains PSFCH, the second to last and third to last symbols in the time slot are used for PSFCH channel transmission, and a time domain symbol before the PSFCH channel is used for protection. Interval GP symbols.

In order to ensure the transmission rate, the 5GS Quality of Service (QoS) mechanism is introduced, as shown in Figure 4. In order to transmit user plane data, one or more Quality of Service flow (QoS Flow) needs to be established. ), and different QoS Flow correspond to different QoS parameters. As an important measure of communication quality, QoS parameters are usually used to indicate the characteristics of QoS Flow.

QoS parameters may include but are not limited to: 5G QoS Indicator (5QI), Allocation And Retention Priority (ARP), Guaranteed Flow Bit Rate (GFBR), Maximum Flow Bits Rate (Maximum Flow Bit Rate, MFBR), Maximum Packet Loss Rate (Maximum Packet Loss Rate) (uplink/downlink), end-to-end packet delay budget (Package delay budget, PDB), access network side packet delay budget (Access Network Package delay budget, AN-PDB), Packet Error Rate (Packet Error Rate, PER), Priority Level, Average Window (Averaging Window), Resource Type (Resource Type), Maximum Data Burst Amount (Maximum Data Burst Volume), UE-aggregate maximum bit rate (Aggregate Maximum Bit Rate, AMBR), session aggregate maximum bit rate (Session-AMBR), etc.

Filter (Filter), also known as Service Data Flow (SDF) template, contains characteristic parameters that describe data packets, and is used to filter out specific data packets to bind to specific QoS Flow. Optionally, Filter is an IP five-tuple, that is, source and destination IP addresses, source and destination port numbers, and protocol type.

The user plane network elements and terminal equipment on the network side can form a filter based on the combination of characteristic parameters of the data packet, which is used to filter the uplink or downlink data packets passed on the user plane that match the data packet characteristics, and bind them to a certain on the data stream.

Combining Figure 4 to illustrate the specific communication method, in the downlink direction, the non-access layer (Non-Access Stratum, NAS) SDF template of the core network classifies and maps different data packets from the application layer to different PDU sessions (session). Different QoS Flows are sent to the RAN in different Protocol Data Unit (PDU) sessions. The RAN maps the QoS Flow ID information to different data radio bearers (Data Radio Bearer, DRB) and sends it to the UE on the air interface. In the same way, similar operations can also be used for uplink data.

Generally speaking, services with high QoS requirements require more wireless communication resources. Therefore, how to balance the QoS requirements of the business with the usage of wireless communication resources is an urgent problem that needs to be solved.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments.
