[0035] For ease of understanding, some contents involved in the embodiments of the present application are described below:
[0036] 1. Introduction to sidelink.
[0037] The Long Term Evolution (LTE) system supports sidelink from the 12th release, which is used for direct data transmission between end user equipment (UE) without going through network equipment.
[0038] The UE sends Sidelink Control Information (SCI) through the Physical Sidelink Control Channel (PSCCH) to schedule the transmission of the Physical Sidelink Shared Channel (PSSCH) to send data. The transmission is carried out in the form of broadcast, and the receiving end does not feedback to the sending end whether the reception is successful.
[0039] LTE sidelink design supports two resource allocation modes, namely scheduled resource allocation mode and autonomous resource selection mode. The former is controlled by the network side equipment and allocates resources to each UE, while the latter is for the UE to autonomously select resources.
[0040] Starting from the 15th release, LTE supports sidelink carrier aggregation (CA). LTE sidelink CA is different from the Uu interface (i.e. downlink and uplink), and there is no distinction between primary component carrier (PCC) and secondary component carrier (SCC). UEs in autonomous resource selection mode perform resource sensing and resource reservation independently on each CC.
[0041] LTE sidelink is designed for specific public safety matters (such as emergency communications at fire sites or disaster sites such as earthquakes), or vehicle to everything (V2X) communications. Vehicle to everything communications include various services, such as basic safety communications, advanced (autonomous) driving, platooning, sensor expansion, etc. Since LTE sidelink only supports broadcast communications, it is mainly used for basic safety communications, and other advanced V2X services will be supported through NR sidelink.
[0042] The 5G NR system can be used in operating frequency bands above 6 GHz that are not supported by LTE, and supports a larger operating bandwidth. However, the current version of the NR system only supports the interface between base stations and terminals, and does not yet support the Sidelink interface for direct communication between terminals.
[0043] Specifically, in the ProSe network architecture, the communication interface between terminals is called the PC5 interface, and the interface connecting the terminal to access network equipment such as the evolved universal mobile telecommunications system (E-UTRAN) is called the Uu interface.
[0044] 2. Sidelink transmission form.
[0045] The current sidelink transmission is mainly divided into broadcast, groupcast and unicast transmission forms. Unicast is one-to-one transmission. Multicast is one-to-many transmission. Broadcast is one-to-many transmission, but broadcast does not have the concept of UE belonging to the same group.
[0046] Currently, Sidelink unicast and multicast communications support the physical layer Hybrid Automatic Repeat request (HARQ) feedback mechanism.
[0047] In addition, NR sidelink defines two modes: one is mode 1, where the base station schedules resources; the other is mode 2, where the UE decides what resources to use for transmission. At this time, the resource information may come from the base station's broadcast message or pre-configuration. If the UE works within the base station range and has an RRC connection with the base station, it can be mode 1 or mode 2. If the UE works within the base station range but has no RRC connection with the base station, it can only work in mode 2. If the UE is outside the base station range, it can only work in mode 2 and perform V2X transmission according to the pre-configured information.
[0048] 3. Sidelink is transmitted in unlicensed spectrum.
[0049] For the unlicensed spectrum sideline (SL-Unlicensed, SL-U), it is necessary to acquire the channel through Listen Before Talk (LBT) before sending SL data.
[0050] In future communication systems, shared spectrum such as unlicensed bands can be used as a supplement to licensed bands to help operators expand services. In order to be consistent with NR deployment and maximize NR-based unlicensed access, unlicensed bands can operate in 5GHz, 37GHz and 60GHz bands. Since unlicensed bands are shared by multiple technologies (RATs), such as WiFi, radar, LTE-LAA, etc., in some countries or regions, unlicensed bands must comply with regulations when used to ensure that all devices can use the resource fairly, such as LBT, Maximum Channel Occupancy Time (MCOT) and other rules. When a transmission node needs to send information, it needs to do LBT first, and perform energy detection (ED) on the surrounding nodes. When the detected power is lower than a threshold, the channel is considered to be idle and the transmission node can send. Otherwise, the channel is considered to be busy and the transmission node cannot send. The transmission node can be a base station, UE, WiFi AP, etc. After the transmission node starts transmitting, the occupied channel time COT cannot exceed MCOT. In addition, according to the occupied channel bandwidth (OCB) regulation, in the unlicensed frequency band, the transmission node must occupy at least 70% (60 GHz) or 80% (5 GHz) of the bandwidth of the entire frequency band during each transmission.
[0051] The types of LBT commonly used in NRU can be divided into Type1, Type2A, Type2B and Type2C. Type1LBT is a channel listening mechanism based on back-off. When the transmitting node senses that the channel is busy, it backs off and continues to listen until it senses that the channel is empty. Type2C is that the sending node does not perform LBT, that is, no LBT or immediate transmission. Type2A and Type2B LBT are one-shot LBT, that is, the node performs LBT once before transmission, and transmits if the channel is empty, and does not transmit if the channel is busy. The difference is that Type2A performs LBT within 25us, which is applicable when the gap between two transmissions is greater than or equal to 25us when the COT is shared. Type2B performs LBT within 16us, which is applicable when the gap between two transmissions is equal to 16us when the COT is shared. In addition, there is Type 2 LBT, which is applicable to LAA, eLAA or FeLAA. When sharing COT, the gap between two transmissions is greater than or equal to 25us, and eNB and UE can use Type 2 LBT. In addition, in the frequency range 2-2, the types of LBT are Type 1, Type 2 and Type 3. Type 1 is a channel listening mechanism based on fallback, Type 2 is one-shot LBT, and 5us LBT is performed within 8us, and Type 3 does not perform LBT.
[0052] 4. Channel occupancy time sharing on the base station side.
[0053] When the base station initiates COT, in addition to using the resources in the COT for downlink transmission, the resources in the COT can also be shared with the UE for uplink transmission. When the resources in the COT are shared with the UE for uplink transmission, the channel access mode that the UE can use is Type 2A LBT, Type 2B LBT or Type 2C LBT.
[0054] 5. Channel Occupancy Time Sharing on the UE Side
[0055] When the UE uses Type1 LBT to initiate a COT, in addition to using the resources in the COT for uplink transmission, the resources in the COT can also be shared with the base station for downlink transmission. In the NR-U system, there are two cases in which the base station shares the COT initiated by the UE: one is that the base station shares the COT of the scheduled PUSCH; the other is that the base station shares the COT of the PUSCH that is exempted from scheduling authorization.
[0056] 6. Channel Access Priority Class (CAPC).
[0057] Before seizing a channel, the eNB, gNB or UE must determine a CAPC value and use it to look up a table to determine the window parameters for channel access and LBT. The CAPC value ranges from p=1 to 4, where p=1 represents the highest priority and its corresponding LBT window is shorter than that of other priorities, that is, the time required for successful LBT with p=1 is shorter on average than that with p=2, 3 or 4. However, the maximum length of COT that can be occupied is also relatively shorter, which reflects a certain degree of fairness in the seizure of channels by different devices.
[0058] For p=3 and p=4, if it is guaranteed that no other RAT shares this channel in the long run, T mcot,p =10ms; otherwise, T mcot,p =8ms.
[0059] When the UE needs to send uplink data and perform LBT, it needs to determine the CAPC value of this LBT according to the type of data to be sent, as agreed by the protocol or configured by the network. Among them, when the data that the UE needs to send includes data carried by signaling radio bearer (SRB) 0, SRB1 or SRB3, p=1 is always used by default. For SRB2 or data radio bearer (DRB), the network side equipment can configure the CAPC value for the UE to send data carried by SRB2 and DRB.
[0060] The transmission processing method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0065] Optionally, after the second terminal obtains COT through LBT, it can share the COT with other terminals (such as the first terminal), that is, share the resources in the COT with the first terminal. The first terminal receives the above-mentioned shared COT. Since the resource allocation mode of the first terminal is resource allocation mode 1, it can send the first information to the network side device based on the shared COT. At this time, the network side device can optimize the resource scheduling of the first terminal based on the first information. For example, the resources that can be scheduled are located in the shared COT, so that the first terminal can reduce the delay of data transmission in the unlicensed spectrum and improve the reliability of transmission. For another example, when performing resource scheduling, the scheduling of resources transmitted in the COT is not considered to reduce the signaling overhead.
