In order to understand characteristics and technical contents in the embodiments of the present disclosure in more detail, the implementation of the embodiments of the disclosure is elaborated in combination with the accompanying drawings. The accompanying drawings are only used for reference, but not intended to limit the embodiments of the disclosure.
Unicast connection and multicast connection are introduced in Vehicle to Everything (V2X) of the 5th Generation (5G) New Radio (NR) system. However, for how to realize the control between electronic devices, such as the control of a terminal device by a network device, or the control between a first terminal device and a second terminal device, there is no effective solution at present.
Before a detailed description of the embodiments of the disclosure, a brief description of an Internet of Vehicles (IOV) system is given.
The IOV system refers to a Side Link (SL) transmission technology based on Device to Device (D2D) communication. Different from the traditional mode of receiving or sending communication data through a base station in a Long Term Evolution (LTE) system, a D2D direction communication mode is used for the communication data in the IOV system, which has higher spectral efficiency and lower transmission latency.
V2X is standardized in the 3GPP Rel-14, and two transmission modes, namely mode 3 and mode 4, are defined.
For the mode 3, a data transmission process is shown in
The base station may allocate either resources for single transmission or resources for semi-static transmission.
For the mode 4, a data transmission process is shown in
On one hand, a unicast connection and a multicast connection are introduced in NR-V2X. However, under the unicast connection or the multicast connection, there is no solution for how the network device controls the terminal device to report related information, and how the network device realizes a deep control over the unicast connection or multicast connection of the terminal device. On the other hand, a UE-UE control is introduced in NR-V2X. However, there is no effective solution for the realization of the UE-UE control, such as how to trigger UE-UE capability interaction and mutual control, what granularity is adopted to perform interaction control, how to determine a controlling end and a controlled end, and how to handle abnormal conditions.
Therefore, the disclosure provides a method for information processing. The information processing method of the embodiments of the disclosure may be applied to various communication systems, for example, a Global System of Mobile communication (GSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system or a 5G system.

The PLMN categories of the second terminal device include a same PLMN and a different PLMN. The source address and the target address may not be all address information but are represented using a simplified address index. For example, if the address index is an address of 24 bits in length, an address list reported by the terminal device to a network includes 16 addresses, then the specific address in the address list may be identified by 4 bits instead of 24 bits, so network overhead can be saved.
The first terminal device reports the D2D connection situation to the network device according to different situations. Optionally, the situations include at least one of the following: the propagation mode, the identifier of the second terminal device, the PLMN identifier of the second terminal device and/or the PLMN category of the second terminal device, the target address and/or the source address, the PSID, the ITS-AID, the access mode, the bearer, the logical channel, the channel condition, the speed, the synchronization type, or the communication mode.

Taking that the connection situation is the propagation mode and the preprocessing is the average value processing as an example, the propagation mode includes multicast, broadcast and unicast. The value corresponding to multicast is 1, the value corresponding to broadcast is 2, the value corresponding to unicast is 3, and a value obtained by performing the average value processing on the propagation modes is 2. Therefore, the preprocessing refers to performing the maximum value processing, the minimum value processing or the average value processing on different values corresponding to various situations. When the D2D connection situation includes the propagation mode and the access mode, the propagation mode and the access mode are preprocessed respectively. The above is just an example of preprocessing.
In the embodiments of the disclosure, the D2D connection situation also includes: related parameters of a bearer of the first terminal device. Optionally, the related parameters of a bearer of the first terminal device include at least one of the following:
In the specific implementation, the first terminal device transmits an uplink control channel to the network device, and the uplink control channel carries the D2D connection situation. Or, the first terminal device transmits an uplink data channel to the network device, and the uplink data channel carries the D2D connection situation. Or, the first terminal device sends uplink RRC signaling to the network device, and the RRC signaling bears the D2D connection situation. Or, the first terminal device sends a Scheduling Request (SR) to the network device, and the SR carries the D2D connection situation. Or, the first terminal device sends a Buffer Status Report (BSR) to the network device, and the BSR carries the D2D connection situation.
Optionally, when the D2D connection situation is sent from the first terminal device to the network device by transmitting the uplink control channel, the D2D connection situation may be borne through a Physical Uplink Control Channel (PUCCH), and different PUCCH formats may transmit different numbers of bits of information, therefore, the corresponding PUCCH format may be used for bearing different contents included in the D2D connection situation.
Optionally, when the D2D connection situation is sent from the first terminal device to the network device by transmitting the uplink control channel, the first terminal device also receives Downlink Control Information (DCI) sent by the network device. The DCI is used for allocating SL transmission resources for the first terminal device. The DCI carries indication information which is used for determining the transmission resources of the uplink control channel.
For example, the network device sends configuration information to the first terminal device, and the configuration information is used for configuring a transmission resource set of the PUCCH. The network device allocates the SL transmission resources to the first terminal device through the DCI. The DCI may carry the indication information which is used for determining the transmission resources of the PUCCH in combination with the configuration information. Specifically, for example, the indication information includes index information which is used for determining a transmission resource from multiple transmission resources of the PUCCH which are configured by the network. Alternatively, the indication information indicates a time interval between the PUCCH and the DCI, and further, may indicate frequency domain resources of the PUCCH, therefore the transmission resources of the PUCCH for transmitting the D2D connection situation may be determined.
The above description is made by taking that the configuration information is used for configuring the transmission resource set of the PUCCH as an example. In the specific implementation, the configuration information may also be used for configuring a transmission resource set of a Physical Sidelink Share Channel (PSSCH).

The DCI may carry the indication information which is used for determining the transmission resources of the PSSCH in combination with the configuration information. Specifically, for example, the indication information includes index information which is used for determining a transmission resource from multiple transmission resources of the PSSCH which are configured by the network. Alternatively, the indication information indicates a time interval between the PSSCH and the DCI, and further, may indicate frequency domain resources of the PSSCH, therefore the transmission resources of the PSSCH for transmitting the D2D connection situation may be determined.
In a second optional embodiment, the second electronic device is the second terminal device. Correspondingly, that the first terminal device sends information to the second electronic device is that: the first terminal device sends a first message to the second terminal device, the first message being used for triggering the second terminal device to send a first parameter combination to the first terminal device. The first parameter combination indicates at least one of an SL data sending parameter of the second terminal device or an SL data receiving parameter of the second terminal device. The second terminal device is different from the first terminal device.
In some embodiments, the second terminal device may send the first parameter combination to the first terminal device through a Physical Sidelink Control Channel (PSCCH), or a PSSCH, or a sidelink feedback channel, or a Physical Sidelink Discovery Channel (PSDCH), etc.

The high layer information is carried in the RRC signaling and is sent simultaneously to the first terminal device with the first parameter combination. The high layer information includes at least one of the following:
a connection establishment request message DIRECT_COMMUNICATION_REQUEST, a security parameter configuration message DIRECT_SECURITY_MODE_COMMAND, a security parameter configuration completion message DIRECT_SECURITY_MODE_COMPLETE, or a connection establishment completion message DIRECT_COMMUNICATION_ACCEPT.
In the specific implementation, that the second terminal device sends the first parameter combination to the first terminal device may be triggered by an access layer of the second terminal device. As an example, when at least one of the SL data sending capability of the second terminal device or the SL data receiving capability of the second terminal device changes, the second terminal device triggers the second terminal device to send the first parameter combination to the first terminal device.
It may be understood as that the high layer information of the second terminal device triggers the second terminal device to send the first parameter combination to the first terminal device, or the first terminal device triggers by sending the first message the second terminal device to send the first parameter combination to the first terminal device. Whether the sending of the first parameter combination is triggered by the high layer information of the second terminal device or by the first message of the first terminal device, it may be triggered periodically. That is, the high layer of the second terminal device triggers periodically the second terminal device to send the first parameter combination to the first terminal device, or the first terminal device periodically sends the first message to trigger the second terminal device to send the first parameter combination to the first terminal device.

For example, the first parameter in the first parameter combination includes different dimensions, such as the QoS attribute, the propagation mode, the identifier of the second terminal device, the target address, the source address, the PSID, the ITS-AID, the RAT, and the parameter configuration information delivered by the high layer of the second terminal device. Optionally, the type of the first parameter in the embodiments of the disclosure refers to different dimensions of the first parameter. The propagation mode includes unicast, multicast and broadcast. The RAT includes accessing in the NR system and accessing in the LTE system.
