[0002] New Radio (NR) - Vehicle to Everything (V2X) system supports two resource allocation modes, in which mode 1 is a base station controlled resource allocation mode, and mode 2 is a terminal autonomous resource allocation mode.
[0003] For the mode 2 resource allocation mode, a user equipment (UE) determines a sidelink transmission resource by sensing, and a receiving UE needs to detect all the time to obtain the scheduling information of the sidelink control information (SCI) and correctly receive the sidelink transmission. In each resource pool, there can be multiple types of services, and different types of services are suitable for different discontinuous reception (DRX) configurations. The same receiving UE can use different DRX configurations when communicating with different transmitting UEs. Therefore, the transmitting UE also needs to consider the DRX configuration of the receiving UE when performing sidelink transmission with different receiving UEs, so as to avoid resource selection in the inactive period of the receiving UE, resulting in that the data cannot be correctly received.

[0059] The present application will be further described below in conjunction with the drawings and specific embodiments.
[0060] The technical solution of the embodiment of the present application can be applied to a vehicle Internet system. The vehicle Internet is a huge interactive network composed of information such as vehicle position, speed and route. Through devices such as a global positioning system (GPS), radio frequency identification (RFID), sensors, camera image processing, a vehicle can collect its own environmental and state information. Through Internet technology, all vehicles can transmit their various information to a central processor. Through computer technology, the information of a large number of vehicles can be analyzed and processed, so as to calculate the best route of different vehicles, report road conditions in time, arrange signal light periods, etc.
[0061] Data transmission in the vehicle-to-everything system can be based on a mobile communication network, such as a Global System for Mobile Communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS) system, a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, a Universal Mobile Telecommunication System (UMTS) system, a Worldwide Interoperability for Microwave Access (WiMAX) communication system, or a 5G system. Alternatively, the 5G system or 5G network can also be referred to as an NR system or an NR network.
[0062] For example, the vehicle-to-everything system to which the embodiments of the present application are applied can be as shown in Figure 1a and Figure 1b The vehicle-to-everything system can include a network device and a terminal. The network device can be a device that communicates with the terminal (or a communication terminal, a terminal device, a user equipment, etc.). The network device can provide communication coverage for a specific geographic area and can communicate with terminals located in the coverage area. Alternatively, the network device can be a base station (BTS, Base Transceiver Station) in a GSM system or a CDMA system, a base station (NB, NodeB) in a WCDMA system, an evolved base station (eNB or eNodeB, Evolutional Node B) in an LTE system, or a radio controller in a cloud radio access network (CRAN, Cloud Radio Access Network), etc.
[0063] The terminal in the embodiments of the present application is a vehicle-mounted terminal mounted in a vehicle,
[0064] For example, the data transmission mode in the vehicle-to-everything system in the embodiments of the present application can be as shown in Figure 1a and Figure 1b For example, the data transmission mode in the vehicle-to-everything system in the embodiments of the present application can be as shown in Figure 1aAs shown, the terminal's transmission resources are provided by network devices (e.g., Figure 1a The eNB shown is allocated via the downlink (DL); the terminal transmits data on the sidelink (SL) according to the transmission resources allocated by the network equipment. (See reference...) Figure 1b As shown, the terminal employs a sensing + reservation transmission method. The terminal obtains a set of available transmission resources from the resource pool through sensing, selects a transmission resource from this set, and transmits data via SL based on the selected transmission resource.
[0065] Figure 1a and Figure 1b An exemplary embodiment shows a network device and two terminals. Optionally, the vehicle networking system may include multiple network devices and each network device may include other numbers of terminals within its coverage area. This embodiment does not limit this.
[0066] Optionally, the vehicle networking system may also include other network entities such as network controllers and mobility management entities, which are not limited in this application embodiment.
[0067] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0068] Since different terminal devices may be configured with different DRX configurations for different service types, the resource pool may be configured with multiple sets of DRX configurations to adapt to the transmission of different service types. At the same time, different receiving UEs may use different DRX configurations. In order to enable the sending UE to know the DRX configuration used by the receiving UE, so that the transmitting and receiving ends have a consistent understanding, the following embodiments of the present invention are proposed.
[0069] This invention provides an information indication method. Figure 2 This is a flowchart illustrating the information indication method according to an embodiment of the present invention; as shown below. Figure 2 As shown, the method includes:
[0070] Step 101: The first terminal device sends first indication information to at least one second terminal device through a specific channel; the first indication information is used to indicate first DRX configuration information;
[0071] The first transmission resource carrying the specific channel is related to the identity of the first terminal device or related to the identity of the first terminal device and the identity of the second terminal device.
[0072] Based on the consideration that different terminal devices may configure different DRX configuration information for different service types, each resource pool may configure multiple sets of DRX configuration information to adapt to different service type transmissions. Different terminal devices may use different DRX configuration information at the same time. In order to enable the sending terminal device to know the DRX configuration used by the receiving terminal device, in this embodiment, the first indication information is used to indicate the first DRX configuration information, so that the sending terminal device and the receiving terminal device can obtain consistent understanding.
[0073] This embodiment is applied in the first terminal device. For example, NR-V2X supports three modes of unicast, groupcast and broadcast. In different modes, the first terminal device may be a sending terminal device or a receiving terminal device.
[0074] In the application of this embodiment, the first indication information can be explicit indication or implicit indication. Explicit indication means that the first indication information carries information bits for indicating the DRX configuration information. Implicit indication means that the first indication information carries the DRX configuration information through the first transmission resource, and the sending terminal and the receiving terminal of the indication information can determine the DRX configuration information through the correspondence between the first transmission resource and the DRX configuration information, without additional information bits.
[0075] In some optional embodiments, when the first terminal device and the at least one second terminal device perform broadcast or groupcast service, the first terminal device is a sending terminal device, and the at least one second terminal device is a receiving terminal device; when the first terminal device and the second terminal device perform unicast service, the first terminal device is a receiving terminal device, and the second terminal device is a sending terminal device.
[0076] In the embodiment, for broadcast or groupcast service, if the receiving end device has multiple, if the sending end device receives different DRX configuration information from each receiving end device, and then finds the activation time common to each receiving end device for broadcast or groupcast, the restriction on the sending end device is greater, therefore in this case, it is more appropriate to use the indication of the DRX configuration information of the receiving end device by the sending end device, that is, the first terminal device is the sending end device, and correspondingly, the second terminal device is the receiving end device. For unicast service, the sending end device needs to determine the window of sensing and resource selection according to the DRX configuration information of the receiving end device, so as to ensure that the selected resource is within the activation of the receiving end device, therefore, in this case, the receiving end device needs to indicate its own DRX configuration information to the sending end device, that is, the first terminal device is the receiving end device, and correspondingly, the second terminal device is the sending end device.
[0077] In the embodiment, the identifier of each terminal device (the identifier of the first terminal device, or the identifier of the first terminal and the identifier of the second terminal) corresponds to the first transmission resource, and then the first indication information of each terminal device is distinguished through the different first transmission resources corresponding to the identifier of each terminal device. Through this indication mode, the indication of the DRX configuration information of different terminal devices is realized, so as to realize the consistent understanding of the DRX configuration of the receiving and sending terminal devices in the NR-V2X mode 2.
[0078] In some optional embodiments, the specific channel is PSFCH or other physical channels carrying information in sequence.
[0079] In the embodiment, considering that the PSFCH adopts a periodic structure for transmission, the first indication information can be carried through the PSFCH. In addition, the embodiment is not limited to carrying the first indication information through the PSFCH, but can also carry the first indication information through other physical channels carrying information in sequence. The name and type of the other physical channels carrying information in sequence are not limited in the embodiment, but the carrying mode is to carry information through a sequence occupying certain time domain and frequency domain resources. Optionally, the other physical channels carrying information in sequence can be periodic physical channels. In the embodiment, the first indication information is indicated to the second terminal device through the periodic specific channel, the identifier of each terminal device (the identifier of the first terminal device, or the identifier of the first terminal and the identifier of the second terminal) corresponds to different first transmission resources, and then the first indication information of each terminal device is distinguished through the different first transmission resources corresponding to the identifier of each terminal device, so as to realize the acquisition of the DRX configuration information by the receiving end device.
[0080] In the embodiment, as to the content of the indication information (e.g., the first indication information), for example, in the DRX configuration information list configured by each resource pool, different DRX configuration information corresponds to different indexes, and the first indication information can be the index corresponding to the DRX configuration information, so as to indicate the corresponding DRX configuration information, thereby achieving the indication of the DRX configuration information. In the case of using different sequences to indicate the DRX configuration information, a one-to-one correspondence between the different sequences and the DRX configuration information can be established, so that the receiving end device can determine the DRX configuration information corresponding to the sequence by detecting the sequence.
[0081] In some optional embodiments of the present application, the method further comprises: determining, by the first terminal device, the first transmission resource carrying the specific channel based on the resource configuration information sent by the network device or the pre-configured resource configuration information.
[0082] The resource configuration information comprises at least one of the following:
[0083] a transmission period;
[0084] a candidate time slot or a number of continuous time slots in the transmission period;
[0085] a time slot offset value;
[0086] a number of candidate PRBs of the specific channel;
[0087] a number of cyclic shifts;
[0088] a number of PRBs occupied by the transmission of the specific channel.
[0089] In the embodiment, the above resource configuration information can be configured by the network device (e.g., a base station) to the first terminal device, or can be obtained by the first terminal device in advance (or in a conventional manner), and the first terminal device can determine the first transmission resource carrying the specific channel based on the above resource configuration information. The transmission period can be a transmission period of the specific channel, and the number of cyclic shifts can be a number of cyclic shifts of each RB or PRB.
[0090] In some optional embodiments of the present invention, the first transmission resource includes at least one of the following resources: time-domain resources, frequency-domain resources, and code-domain resources; the method further includes: the first terminal device determining a first time slot within the transmission period based on the identifier of the first terminal device and the number of candidate time slots, or the identifier of the first terminal device and the number of continuous time slots; or, the first terminal device determining a first time slot within the transmission period based on the identifier of the first terminal device, the identifier of the second terminal device, and the number of candidate time slots, or the identifier of the first terminal device, the identifier of the second terminal device, and the number of continuous time slots; the first terminal device determines the first transmission resource within the first time slot.
[0091] In this embodiment, considering that the terminals on both sides of the side link (i.e., the transmitting and receiving devices, or the first and second terminal devices) cannot transmit and receive simultaneously, it is necessary to distribute the terminals in time, with different terminals transmitting indication information at different times, and the receiving terminal receiving it. Based on this, the first implementation is that the first terminal device determines the first time slot within the aforementioned transmission period based on its identifier and the number of candidate time slots; the second implementation is that the first terminal device determines the first time slot within the aforementioned transmission period based on its identifier and the number of continuous time slots; the third implementation is that the first terminal device determines the first time slot within the aforementioned transmission period based on the identifiers of both the first and second terminal devices, and the number of candidate time slots; the fourth implementation is that the first terminal device determines the first time slot within the aforementioned transmission period based on the identifiers of both the first and second terminal devices, and the number of continuous time slots. Then, the first transmission resource within the first time slot is determined.
[0092] For example, the resource configuration information includes the transmission period and the number of continuous time slots within the transmission period. That is, in addition to the transmission period, the resource configuration information also includes the duration T. d .like Figure 3 As shown in the figure, each transmission cycle includes four duration slots (each box in the figure represents one duration slot), and these four duration slots form the duration T. d These four continuous time slots can then be used to indicate the DRX configuration information for different terminals.
[0093] As an example, for broadcast or multicast services, suppose the identifier of the first terminal device is G. ID Or the destination group ID is G IDwherein the destination group identity can be an identity corresponding to a group in the groupcast service. Then the first time slot can correspond to the nth time slot in the transmission period, n = G ID mod T d , where mod denotes a modulo operation.
[0094] As another example, for unicast service, assuming the identity of the first terminal device is G ID1 , and the identity of the second terminal device is G ID2 , then the first time slot can correspond to the nth time slot in the transmission period, n = (U ID1 + U ID2 ) mod T d , where mod denotes a modulo operation.
[0095] Of course, in the above examples, whether it is unicast service or groupcast / broadcast service, only the identity of the sending terminal device is considered to determine the first time slot, i.e. in the above second example, assuming the second terminal device is the sending terminal device, then n = (U ID2 ) mod T d , where mod denotes a modulo operation.
[0096] In this embodiment, after determining the first time slot, further determine which frequency domain resources and / or code domain resources, etc. corresponding to the DRX configuration information are used.
[0097] Currently, the resource of PSFCH is determined according to the transmission resource of PSFCH, but when PSFCH is used to indicate DRX configuration information, there is no corresponding physical sidelink shared channel (PSSCH, Pysical Sidelink Share Channel), so it is necessary to re-determine the relationship between the transmission resource of PSFCH and the terminal device to be indicated. The transmission resource of PSFCH includes at least one of the following resources: time domain resource, different orthogonal frequency division multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) symbols, frequency domain resource, different PRBs, code domain resource, different cyclic shifts, etc.
[0098] As an optional implementation, the resource of a specific channel used to indicate the DRX configuration information is associated with the identity of the terminal device. Optionally, for broadcast service or groupcast service, the first transmission resource can be related to the identity of the sending terminal device or the group identity of the groupcast. As another implementation, for unicast service, since one sending terminal device can have a sidelink transmission with one or more receiving terminal devices, the first transmission resource can be related to the identity of the sending terminal device and the identity of the receiving terminal device.
[0099] In some optional embodiments, the first terminal device determines the first transmission resource in the first time slot, including: the first terminal device groups PRB resources in the first time slot based on the number of DRX configuration information, to obtain a transmission resource group corresponding to each DRX configuration information; and the first terminal device determines the first transmission resource in the first transmission resource group corresponding to the first DRX configuration information based on an identifier of the first terminal device, or based on the identifier of the first terminal device and an identifier of the second terminal device.
[0100] In the embodiment, the first terminal device groups PRB resources in the first time slot according to the number of configured DRX configuration information, and each transmission resource group corresponding to each DRX configuration information can include the same PRB resource or different PRB resources; and the corresponding first transmission resource is determined in the first transmission resource group according to the identifier of the first terminal device, or according to the identifier of the first terminal device and the identifier of the second terminal device. The PRB resource can also be a resource block (RB) resource.
[0101] The DRX configuration list can be preconfigured, and the DRX configuration list includes N DRX configuration information, where N is a positive integer. The number of DRX configuration information is the number of DRX configuration information included in the DRX configuration list.
[0102] For example, assuming that D DRX configuration information is configured, all PRB resources in the first time slot are divided according to the number of DRX configuration information (i.e., D), and the number of RB resources corresponding to each DRX configuration information is N D = N T / D; where N T represents the number of RBs of a specific channel, and the number of resources corresponding to each DRX configuration information is N where N1 represents the number of PRBs of a specific channel, and N CS represents the number of cyclic shifts. The corresponding first transmission resource is determined in the first transmission resource group according to the identifier of the first terminal device, or according to the identifier of the first terminal device and the identifier of the second terminal device.
[0103] As an example, for broadcast service or groupcast service, assuming that the identifier of the first terminal device is G ID , or the destination group ID is G ID , the following expression can be used to determine the first transmission resource group:
[0104]
[0105] wherein floor denotes a floor operation, mod denotes a modulo operation, R denotes a resource number corresponding to each DRX configuration information; T d denotes a continuous time slot number or a continuous time length.
[0106] In other examples, the following expression can also be used to determine the first transmission resource group: ID mod R.
[0107] As another example, for the case of unicast service, the following expression can be used to determine the first transmission resource group:
[0108]
[0109] wherein floor denotes a floor operation, mod denotes a modulo operation, R denotes a resource number corresponding to each DRX configuration information; T d denotes a continuous time slot number or a continuous time length, G ID2 denotes an identity of the second terminal device, G ID1 denotes an identity of the first terminal device.
[0110] In other examples, the following expression can also be used to determine the first transmission resource group: ID1 + U ID2 mod R.
[0111] Optionally, the determining the first transmission resource in the first transmission resource group corresponding to the first DRX configuration information based on the identity of the first terminal device, or based on the identity of the first terminal device and the identity of the second terminal device, comprises: the first terminal device determines a resource number of a specific channel corresponding to the first DRX configuration information based on a PRB resource number in the first transmission resource group corresponding to the first DRX configuration information, determines the first transmission resource based on the identity of the first terminal device and the resource number of the specific channel, or determines the first transmission resource based on the identity of the first terminal device, the identity of the second terminal device and the resource number of the specific channel.
[0112] As an example, for the case of broadcast service or groupcast service, assuming that the identity of the first terminal device is G ID , or a destination group ID is G ID , the first transmission resource (e.g. PRB resource) determined in the first transmission resource group can be represented as:
[0113]
[0114] wherein floor denotes a floor operation, mod denotes a modulo operation, R denotes a number of resources corresponding to each DRX configuration information, T d denotes a number of continuous time slots or a continuous time length.
[0115] In other examples, G ID mod R determines the first transmission resource.
[0116] As another example, for the case of unicast service, the first transmission resource (e.g., PRB resource) determined in the first transmission resource group can be expressed as:
[0117]
[0118] wherein floor denotes a floor operation, mod denotes a modulo operation, R denotes a number of resources corresponding to each DRX configuration information, T d denotes a number of continuous time slots or a continuous time length, G ID2 denotes an identity of the second terminal device, G ID1 denotes an identity of the first terminal device.
[0119] In other examples, G ID1 + U ID2 mod R determines the first transmission resource.
[0120] In this embodiment, for the differentiation of broadcast / groupcast and unicast UEs, different periodic offset parameters can be configured for different terminal devices, so that the time slots of the specific channels (such as PSFCH) where different terminal devices are located are different. It can also be configured in the same time slot, but different PRB resources or RB resources are configured to distinguish through the frequency domain.
[0121] In all specific channel (such as PSFCH) resources corresponding to each DRX configuration, the numbering order of the resources is the frequency domain (such as RB) first, and then the cyclic shift. The terminal determines the first transmission resource in the first transmission resource group based on the above determination method.
[0122] In some optional embodiments, the first terminal device determines the first resource in the first time slot, including: the first terminal device groups PRB resources in the first time slot to obtain a plurality of transmission resource groups; each transmission resource group includes at least one PRB resource; the first terminal device determines a second transmission resource group corresponding to the first terminal device based on the identity of the first terminal device, or based on the identity of the first terminal device and the identity of the second terminal device; and the first terminal device determines the first transmission resource in the second transmission resource group through the correspondence between the cyclic shift parameter and the DRX configuration information.
[0123] In this embodiment, different cyclic shift parameters correspond to different DRX configuration information. Specifically, the first network device first groups the PRB resources (or RB resources) in the first time slot, for example, divides them into N groups, N can be equal to the number of PRBs or RBs in the first time slot, that is, the number of transmission resource groups is the same as the number of PRBs or RBs; in other embodiments, the number of transmission resource groups can also be less than the number of PRBs or RBs, that is., a plurality of PRBs or RBs correspond to one transmission resource group.
[0124] For the first terminal device to determine the transmission resource group it is in, similar to the foregoing embodiment, based on the identity of the first terminal device, or based on the identity of the first terminal device and the identity of the second terminal device, the second transmission resource group corresponding to the first terminal device is determined.
[0125] As an example, for the case of broadcast service or groupcast service, assuming that the identity of the first terminal device is G ID , or the destination group ID is G ID , the following expression can be used to determine the second transmission resource group:
[0126]
[0127] Wherein, floor represents the down rounding operation, mod represents the modulo operation, N represents the number of transmission resource groups, T d represents the number of continuous time slots or the continuous time length.
[0128] In other examples, G ID mod N can also be used to determine the first transmission resource group.
[0129] As another example, for the case of unicast service, the following expression can be used to determine the second transmission resource group:
[0130]
[0131] Wherein, floor represents the down rounding operation, mod represents the modulo operation, N represents the number of transmission resource groups; T d represents the number of continuous time slots or the continuous time length, G ID2 represents the identity of the second terminal device, G ID1 represents the identity of the first terminal device.
[0132] In other examples, (U ID1 + U ID2 )mod N can also be used to determine the second transmission resource group.
[0133] Further, since the corresponding DRX configuration information is indicated by different cyclic shift parameters, the first terminal device determines a first cyclic shift parameter corresponding to the first DRX configuration information, determines a PRB resource or a RB resource corresponding to the first cyclic shift parameter in the second transmission resource group, and further sends the first indication information through the specific channel by using the determined PRB resource or RB resource.
