[0060] To facilitate a clearer understanding of the technical solutions provided in the various embodiments of this application, some relevant background knowledge will be introduced as follows.

[0061] I. Introduction to Vehicle-to-Everything (V2X)

[0062] Figure 2 This is a schematic diagram of uplink (UL), downlink (DL), and SL transmission in related technologies, as shown below. Figure 2As shown, SL transmission refers to data transmission between UEs directly at the physical layer, without going through network devices. LTE sidelink is broadcast-based and can be used to support basic security classes of V2X communication. 5G NR systems can support more advanced SL transmission designs, such as unicast, multicast, or groupcast, thus supporting a wider range of service types.

[0063] II. SL TB (Transport Block) transmission;

[0064] In SL, the Physical Sidelink Shared Channel (PSSCH) is used to transmit data. The control information associated with the PSSCH is carried in the Physical Sidelink Control Channel (PSCCH) and the Sidelink Control Information (SCI) of the PSSCH.

[0065] SCI is divided into two levels: the first-stage SCI is in the PSCCH, and the second-stage SCI is in the PSSCH. Terminals detect SCI to obtain reserved resources from other terminals or base stations, and then select appropriate resources for transmission. Simultaneously, terminals need to detect SCI to determine if there is any data being transmitted to them, and then receive the data sent to them.

[0066] NR V2X defines two resource allocation modes: mode 1, where resources are allocated by the base station; and mode 2, where the UE decides which resources to use for transmission. Resource information may come from base station broadcast messages or pre-configured information. If the UE is within range of the base station and has a Radio Resource Control (RRC) connection with the base station, it can operate in mode 1 and / or mode 2. If the UE is within range of the base station but does not have an RRC connection, it can only operate in mode 2. If the UE is outside range of the base station, it can only operate in mode 2 and perform V2X transmission according to the pre-configured information.

[0067] For mode 2, the specific working method is as follows:

[0068] 1) TX (Transmission): After resource selection is triggered, the UE first determines the resource selection window. The lower boundary of the resource selection window is at time T1 after the resource selection is triggered, and the upper boundary of the resource selection is at time T2 after the trigger. T2 is the value selected by the UE in its TB transmission PDB (packet delay budget). T2 is not earlier than T1.

[0069] 2) Before selecting resources, the UE needs to determine the candidate resource set. The reference signal received power (RSRP) measured on the resource in the resource selection window is compared with the corresponding RSRP threshold. If the RSRP is lower than the RSRP threshold, then the resource can be included in the candidate resource set.

[0070] 3) After the resource set is determined, the UE randomly selects transmission resources from the candidate resource set. In addition, the UE can reserve transmission resources for subsequent transmissions during this transmission.

[0071] Furthermore, NR V2X supports chained resource reservation, meaning that an SCI can reserve the current resource, and then reserve up to two more resources in the next resource allocation. Within the selection window, resources can be continuously reserved dynamically.

[0072] 3. Listen before you speak (LBT);

[0073] In future communication systems, unlicensed bands can supplement licensed bands, helping operators expand service capacity. To maintain consistency with NR deployments and maximize NR-based unlicensed access, unlicensed bands can operate in the 5GHz, 37GHz, and 60GHz bands. The large bandwidth (80 or 100MHz) of unlicensed bands reduces the implementation complexity of base stations and UEs. Since unlicensed bands are shared by multiple technologies (RATs), such as WiFi, radar, and LTE-LAA (License Assisted Access), in some countries or regions, unlicensed band usage must comply with regulations to ensure fair resource use for all devices. These regulations include LBT (Large-Time Bypass) and Maximum Channel Occupancy Time (MCOT) rules. When a transmitting node needs to send information, it first performs LBT, conducting energy detection (ED) on surrounding nodes. When the detected power is below a threshold, the channel is considered idle, and the transmitting node can transmit. Conversely, if the channel is busy, the transmitting node cannot send data. This process can be considered as channel access.

[0074] The following description, in conjunction with the accompanying drawings, details the auxiliary information transmission method, the first device, and the second device provided in this application through some embodiments and application scenarios.

[0075] The transmission method based on auxiliary information provided in this application embodiment can be applied to a first device, which can be a terminal or a network-side device. The first information assists the first device or other devices in performing SL transmission, thereby alleviating resource conflicts in the transmission between devices. The aforementioned auxiliary information is also the first information in this application embodiment.

[0076] Figure 3 This is one of the flowcharts illustrating the auxiliary information-based transmission method provided in this application embodiment, such as... Figure 3 As shown, the method includes step 301; wherein:

[0077] Step 301: The first device sends first information, which indicates at least one of the following: the first device performs channel access on at least one first resource; the first device performs transmission on at least one second resource; wherein the at least one second resource corresponds to at least one resource for performing channel access.

[0078] It should be noted that the embodiments of this application can be applied to SL transmission scenarios, wherein the first device can be a terminal or a network-side device. The terminal includes, but is not limited to, the types of terminal 11 listed above, and the network-side device includes, but is not limited to, the types of network-side device 12 listed above. The embodiments of this application do not limit this.

[0079] In related technologies, SL terminals need to detect control information in each slot for resource selection and reception, which leads to high power consumption. Although a partial detection mechanism was introduced in Release 17, allowing power-saving terminals to blindly detect SCI only within a certain window, the power consumption is still high. Therefore, to further reduce the power consumption caused by detection, we can consider how to further reduce the detection of control information.

[0080] This application proposes a contention-based access scheme to reduce the number of blind detections of control information by the terminal, thereby reducing terminal power consumption. However, if only a contention-based access scheme is used for transmission, resource conflicts between terminals may be quite severe. Therefore, it is necessary to consider how to reduce terminal power consumption and alleviate resource conflicts between terminals while maintaining a contention-based access mechanism.

[0081] To address the aforementioned issues, this application provides a transmission method based on auxiliary information, which, on the basis of a contention access mechanism, assists other devices in performing contention access through first information.

[0082] Optionally, the above-mentioned execution of contention access can be understood as: the first device determines whether to perform transmission on at least one second resource corresponding to the at least one first resource based on the channel access situation of the first device on the at least one first resource.

[0083] It's important to note that the contention-based access mechanism can be understood as needing to both detect whether other devices are occupying the channel and inform other devices that they are occupying the channel. One possibility is to send a placeholder signal (e.g., WUS) in advance to reduce the possibility of collisions. At the same time, to save energy, the receiving device cannot continuously detect and control the channel to determine whether to perform reception; otherwise, energy-saving effects will not be achieved.

[0084] Specifically, based on the above contention access mechanism, the first device sends first information (e.g., a WUS signal), which can be used to instruct the first device to perform channel access on at least one first resource. Other devices, such as the second device, can determine whether they also need to perform contention access on the first resource based on the first information, thereby avoiding contention access conflicts as much as possible.

[0085] For example, WUS signals can be used to resolve some resource conflicts in advance. This means that when other terminals receive WUS signals, they are expected to avoid competing for access at the same location, thereby increasing the likelihood of competing for access and avoiding resource conflicts.

[0086] In addition, the second device can also be a device that performs a transmission with the first device. The first information can help the second device determine the first device to perform the transmission. Specifically, the first information sent by the first device indicates the first resource for channel access, thereby determining at least one second resource corresponding to the first resource. Thus, control information is detected or reception is performed only on these second resources, which can effectively reduce the number of resources for the second device to detect control information, thereby reducing the energy consumption of the device.

[0087] In addition, the first information can also be used to instruct the first device to perform a transmission on at least one second resource, which is equivalent to directly instructing the second resource to perform the transmission. In this case, the second device to perform a transmission with the first device can directly determine at least one second resource to perform the transmission, which can effectively reduce the number of resources for the second device to detect and control information, thereby reducing the energy consumption of the device.

[0088] For example, in order to receive data sent to it by other devices, a second device usually needs to detect the control channel to determine whether data is being sent to it. Therefore, in order to save energy, in addition to possible contention access mechanisms, it is possible to consider using auxiliary information to give advance instructions to reduce blind detection on the receiving side.

[0089] It should be noted that the first resource and the second resource mentioned above are only defined by their uses. The first resource is used to perform channel access, and the second resource is used to perform transmission. This application does not limit the specific type of resource. A certain resource is used as the first resource when it is used to perform channel access, and a certain resource is used as the second resource when it is used to perform transmission.

[0090] Optionally, the method by which the first device sends the first information may include:

[0091] The first device sends the first information before performing channel access.

[0092] Specifically, the first device may send the aforementioned first information before performing channel access, that is, before performing contention access, to assist in performing contention access.

[0093] In this embodiment, the first device sends first information to instruct at least one of the following: the first device performs channel access on at least one first resource; the first device performs transmission on at least one second resource. The first information can assist other devices in determining whether to perform contention-based access on the first resource, mitigating resource conflicts when devices perform contention-based access; or, the first information can assist the receiving device in determining the second resource for transmission, filtering out resources that do not participate in transmission, eliminating the need for detection and control information on resources that do not participate in transmission, and thus reducing terminal power consumption to some extent.

[0094] Optionally, the first device may perform channel access on the at least one first resource to obtain a first channel access result;

[0095] Based on the first channel access result, if the first device determines that transmission is to be performed on at least one second resource corresponding to at least one first resource, it sends the second information.

[0096] The second information is used to indicate at least one of the following:

[0097] 1) The first device performs a transmission on at least one transmission resource in the first resource set;

[0098] 2) The first device performs transmission on at least one reserved resource in the first resource set;

[0099] 3) The time-frequency domain location information of the transmitted resources;

[0100] 4) The time-frequency domain location information of the reserved resources;

[0101] 5) Second device identification information, used to indicate the identifier of the device performing the transmission;

[0102] Specifically, the second device identification information may be the identifier of the first device used to send data, which indicates that the second information comes from the first device.

[0103] 6) Third-party device identification information, used to indicate the identifier of the receiving device;

[0104] 7) Second priority information, used to indicate the priority of the first device in performing transmission on the second resource;

[0105] The first resource set includes at least one second resource.

[0106] Specifically, the first device can first perform channel access on at least one first resource to obtain the first channel access result, and then, based on the first channel access result, determine whether to perform transmission on at least one second resource corresponding to at least one first resource, that is, if the first device successfully competes for access on at least one first resource, it can send second information to indicate the relevant information for the second device as the receiving side to perform transmission. For example, when the second resource is multiple slots or a selection window, in order to avoid conflicts, at least one of the sending resource (i.e., transmission resource) and reserved resource can be indicated by auxiliary information such as WUS signal. At the same time, it can also reduce blind detection on the receiving side, thereby achieving energy saving.

[0107] It should be noted that the second resource can be understood as the resource that allows the device to perform transmission after successfully competing for access on the first resource. The transmission resource can be understood as the resource selected from the second resource for the current transmission. The reserved resource also belongs to the second resource, but the reserved resource is a subsequent possible transmission resource used for retransmission or periodic transmission.

[0108] Optionally, the second information may be carried in at least one of the following:

[0109] 1) Preamble;

[0110] 2) Control information;

[0111] 3) Data information.

[0112] Specifically, control information can be understood as information transmitted through control channels. Control information includes, for example, SCI, DCI, UCI (Uplink Control Information) or MAC CE (Medium Access Control Element).

[0113] Optionally, the first device may, based on the first channel access result corresponding to the first resource, determine that channel access on the first resource has failed, and perform at least one of the following:

[0114] 1) Perform channel access on the next first resource among at least one first resource indicated by the first information;

[0115] 2) Perform channel access on the next first resource;

[0116] 3) After the first time unit interval, perform channel access on the next first resource.

[0117] Specifically, if the first device determines that channel access on the first resource has failed based on the first channel access result corresponding to the first resource, that is, if the first device fails to compete for access on the current first resource, then the design synchronization of both the transmitting and receiving sides is required:

[0118] The first device may perform contention access on the next first resource indicated by the first information, where the next first resource is, for example, the next first resource in the time domain;

[0119] The first device can also perform contention access on the next first resource, which can be indicated by other indication information or predefined, and there is no restriction here;

[0120] The first device may also perform contention for access on the next first resource after satisfying the first interval, specifically after the first time unit of the interval. Here, the next first resource may be indicated by the first information or other indication information, or it may be predefined, and there is no restriction here.

[0121] In some embodiments, the first time unit may include at least one of the following: symbol, slot, mini-slot, frame, subframe, microsecond, millisecond, and second.

[0122] In some embodiments, the first device may determine that channel access on the first resource has failed if a third condition is met, based on the first channel access result corresponding to the first resource.

[0123] The third condition may include at least one of the following:

[0124] 1) The channel detection result of the first device on the first resource is greater than a certain threshold; the channel detection result here may include at least one of the following: RSRP, energy detection result, RSSI and SINR;

[0125] 2) The priority of the first device in accessing the channel on the first resource is lower than the priority of other devices in accessing the channel on the first resource;

[0126] 3) The channel access duration of the first device on the first resource is greater than a certain threshold.

[0127] It should be noted that the above threshold values ​​can be set according to actual circumstances, and no restrictions are imposed here.

[0128] Optionally, the first information may be used to indicate at least one of the following:

[0129] 1) The first device performs channel access on at least one first resource;

[0130] Specifically, it can be understood as indicating that a device wants to perform contention access on the first resource through a contention access indication, which can be understood as performing channel access on the first resource.

[0131] In some embodiments, when the first information contains only this information, other devices can avoid conflicts in advance by selecting a first resource that does not indicate the corresponding first resource or indicates fewer first resources to perform contention access.

[0132] In some embodiments, if there is a correspondence between a first resource and a second resource, the first device is instructed to perform channel access on the at least one first resource, that is, implicitly indicating that the first device may perform transmission on the at least one second resource.

[0133] 2) The time-frequency domain location information of the first resource;

[0134] Specifically, when the resource indicated by the first information (e.g., the WUS signal) does not have a fixed mapping relationship with the time domain location of the first resource, it is necessary to indicate the time-frequency domain location of the first resource, which is specifically indicated by the time-frequency domain location information of the first resource.

[0135] In some embodiments, the WUS signal may indicate one or more first resources.

[0136] Optionally, the time-frequency domain location information and the time-frequency domain pattern information of the first resource are associated with at least one of at least a first reference time and at least one first offset.

[0137] The first reference time includes at least one of the following: the start position of the first resource, the end position of the first resource, and the transmission position of the first resource.

[0138] Optionally, the first offset may be one or more, and the number of offsets is equal to the number of indicated resources or the number of resources minus 1.

[0139] In other embodiments, the time-frequency domain location information of the first resource is designed the same as that of the TimeResource Indicator Value (TRIV).

[0140] In some embodiments, if the first information (e.g., a WUS signal) indicates that there is a fixed mapping relationship between the resource and the time domain location of the first resource, the time domain or frequency domain location of the first resource can be determined by the resource where the first information is sent, that is, the time domain or frequency domain location of the first resource is implicitly indicated.

[0141] 3) Time-frequency domain pattern information of the first resource;

[0142] Specifically, the first information may indicate a time pattern as the time-frequency domain pattern information of the first resource, and the time-frequency domain position of the first resource is determined by the time pattern. For example, the time pattern consists of a reference time and at least one offset time. The reference time may be the time indicated by the WUS signal, or the time indicated by the WUS signal plus one offset time.

[0143] In some embodiments, the time-frequency domain location of the first resource, the number of first resources, or the time pattern can be determined based on the congestion situation.

[0144] 4) The first device performs channel access priority on the first resource;

[0145] Specifically, for example, the first device may be instructed to perform channel access priority on the first resource through first priority information, which may include priority or PDB.

[0146] In some embodiments, the device can compare conditions such as priority to ignore contention access indications with lower priority than itself and exclude contention access from being performed on the first resource with a contention access indication with higher priority than itself, thereby avoiding affecting higher priority transmissions.

[0147] In some embodiments, priority or PDB may be explicitly indicated in the first information or implicitly indicated in the first information.

[0148] Implicit indications, for example: the transmission length of the signal carrying the first information can represent different priorities;

[0149] For example, the priority can be determined based on the start / end position of the transmission; for instance, the earlier the transmission position within a slot, the higher the priority.

[0150] For example, the frequency domain in which they reside can be used to differentiate priorities;

[0151] For example, the higher the frequency domain position, the higher the priority;

[0152] For example, the priorities of the preambles in different preamble groups are different.

[0153] 5) Identification of the device performing channel access;

[0154] Specifically, for example, the identifier of the device performing channel access can be indicated by the first device identification information, which may include, for example, a source ID or a destination ID.

[0155] In some embodiments, the second device can determine whether it is receiving on the corresponding second resource by detecting the device ID information carried in the first information. If the corresponding WUS signal is not received, the control information can be left undecoded, thereby achieving energy saving.

[0156] 6) Identification of the device performing the transmission;

[0157] Specifically, for example, the identifier of the device performing the transmission can be indicated by the second device identifier information, which can be the identifier of the first device, to indicate that the first information originates from the first device.

[0158] 7) Identification of the receiving device;

[0159] Specifically, for example, the identifier of the receiving device can be indicated by the third device identification information, such as the destination ID. The advantage of carrying the third device identification information is that the receiving device can determine in advance where the data sent to it is based on the first information, further reducing blind detection and reducing energy consumption; however, the content that the first information needs to carry will increase further.

[0160] 8) Execute the transmission type of the transmission service corresponding to the channel access;

[0161] Specifically, the transmission type is such as broadcast, multicast, or unicast; in some embodiments, different transmission types have different contention access priorities, for example, unicast services give way to multicast services, and multicast services give way to broadcast services.

[0162] 9) The first device performs a transmission on the at least one second resource;

[0163] Specifically, it can be understood as instructing the first device to perform transmission on at least one second resource through a transmission indication. The advantage of sending only this transmission indication is that the design of the first information is simple. When the device detects the first information, it performs a blind check at the corresponding time domain position to determine whether there is data for itself. However, the device needs to perform a blind check at the position corresponding to the first information sent by all devices, which is not suitable for situations with high system load.

[0164] 10) The time-frequency domain location information of the second resource;

[0165] Specifically, compared to sending only transmission instructions, carrying time-frequency domain location information of the second resource allows the receiver to blindly detect fewer second resources, rather than blindly detecting control information in the entire time domain. This further reduces the complexity of blind detection and energy consumption.

[0166] In some embodiments, the time-frequency domain location information of the second resource can be determined by the resource location of the first information, that is, implicitly indicating the time-frequency domain location information of the second resource.

[0167] In some embodiments, the time-frequency domain location information of the second resource may also be indicated by the first information display.

[0168] 11) Time-frequency domain pattern information of the second resource;

[0169] Optionally, the time-frequency domain location information and the time-frequency domain pattern information of the second resource are associated with at least one of at least a second reference time and at least one second offset;

[0170] The second reference time includes at least one of the following: the start position of the second resource, the end position of the second resource, and the transmission position of the second resource.

[0171] 12) The first device performs transmission priority on the second resource;

[0172] Specifically, for example, the first device may be instructed on the priority of transmission on the second resource by using second priority information. The second priority information may include at least one of priority, PDB, number / rate of contention access (continuous) failures / successes, and contention access duration, to assist the receiving device in determining whether to perform reception at the corresponding resource location.

[0173] 13) At least one of transmission resources and reserved resources;

[0174] Specifically, it can be understood as indicating at least one of the transmission resources and reserved resources through the indication of transmission resources or reserved resources; for example, through implicit indication, specifically determined by the location and mapping relationship of the first information, the mapping relationship can be predefined by the protocol, preconfigured by the network side, configured by the network side or indicated by the first device, without limitation here.

[0175] 14) The time-frequency domain location information of the transmission resource;

[0176] Specifically, the time-frequency domain location information of the transmission resource can be determined by a reference time and an offset; wherein, the reference time may be the start position of the first resource set, the end position of the first resource, or the transmission position of the first information; the offset may be one or more, and the number of offsets is equal to the number of indicated resources or the number of resources minus 1. In some embodiments, the time-frequency domain location information of the transmission resource can be the same as the TRIV design, which will not be elaborated here.

[0177] 15) The time-frequency domain location information of the reserved resources.

[0178] Specifically, the determination method for the time-frequency domain location information of reserved resources is similar to that for transmission resources, and will not be elaborated here.

[0179] The information included in the first piece of information may differ in the following three situations, as illustrated below:

[0180] Case 1: When the first information instructs the first device to perform channel access on at least one first resource, the first information may include at least one of the following:

[0181] <1> First indication information (i.e., contention access indication);

[0182] <2> First priority information may include priority, PDB, etc.;

[0183] <3> First equipment identification information;

[0184] <4> Transmission type;

[0185] <5> The time-frequency domain location information of the first resource;

[0186] <6> The time-frequency domain pattern information of the first resource.

[0187] Case 2: When the first information instructs the first device to perform a transmission on at least one second resource, the first information may include at least one of the following:

[0188] <1> Second indication information (i.e., transmission indication);

[0189] <2> The time-frequency domain location information of the second resource;

[0190] <3> The time-frequency domain pattern information of the second resource;

[0191] <4> Second device identification information;

[0192] <5> The second priority information may include at least one of the following: priority, PDB, number / rate of (continuous) failed / successful access attempts, and duration of access attempts.

[0193] Case 3: When the first information indicates at least one of the transmission resources and reserved resources in the first resource set, the first information may include at least one of the following:

[0194] <1> The third indication information (i.e., transmission resource indication);

[0195] <2> Time-frequency domain location information of the transmitted resources;

[0196] <3> Time-frequency domain location information of reserved resources.

[0197] It should be noted that when there is a corresponding relationship between the first resource and the second resource, the first information indicating contention for access can also be considered as a transmission indication.

[0198] In some embodiments, the location where the first information is sent satisfies at least one of the following:

[0199] i. The temporal domain overlaps with the first resource set;

[0200] For example, the time domain overlaps with the first T second resources in the first resource set;

[0201] ii. The time-domain resource location is the time-domain resource location of the first transmission resource indicated -N;

[0202] N can be predefined by the protocol, preconfigured by the network side, configured by the network side, or indicated by the device, and there are no restrictions here.

[0203] Optionally, the first information may be carried in at least one of the following:

[0204] <1> Preamble;

[0205] Specifically, the first information is carried in the Preamble and is applicable to situations where only a contention access indication is sent.

[0206] <2> Control information;

[0207] Specifically, control information includes, for example, SCI, DCI, UCI (Uplink Control Information), or MAC CE (Medium Access Control Element). Control information can be transmitted via a control channel or a data channel.

[0208] In some embodiments, the first information is carried in the DCI, where the first device is a network-side device and the second device is a terminal. In this case, the first information can be carried in the DCI to indicate to the terminal that the network-side device will send data on at least one second resource. The terminal can then avoid blind detection and instead receive data only on the corresponding at least one second resource based on the first information, thereby reducing the terminal's power consumption.

[0209] In other embodiments, the first information is carried in the UCI, where the first device is a terminal and the second device is a network-side device. In this case, the first information can be carried in the UCI to instruct the network-side device that the terminal will send data on at least one second resource. The network-side device can then receive data on the corresponding at least one second resource based on the first information, which can also reduce the transmission power consumption of the network-side device.

[0210] <3> Data information.

[0211] Specifically, data information can be understood as information other than control information transmitted through a data channel.

[0212] Optionally, the first information may occupy T1 time units;

[0213] Where T1 is an integer or fraction greater than 0, and the time unit includes at least one of the following: symbol, time slot, sub-time slot, frame, subframe, microsecond, millisecond, and second.

[0214] Specifically, the first piece of information can occupy T1 symbol / slot / mini-slot / us / ms.

[0215] In some embodiments, when auxiliary information, such as a WUS signal, contains only a contention access indication, a fixed mapping relationship needs to be established between the WUS resources and the first and second resources. In this case, to avoid half-duplex issues, multiple WUS resources need to correspond to one first and one second resource. For example, if one WUS signal occupies only one-quarter of a slot, then the first device can detect whether other devices have sent WUS signals even when it does not send a WUS signal within a slot.

[0216] Optionally, the transmission resources may satisfy at least one of the following:

[0217] <1> The transmission resources of the Physical Control Channel (PCCH) are located in the same resource pool;

[0218] <2> The transmission resources of the Physical Shared Channel (PSCH) are located in the same resource pool;

[0219] Specifically, the transmission resources can be located in the same resource pool as the transmission resources of the PCCH / PSCH.

[0220] For example, transmission resources can reuse the PSFCH (physical sidelink feedback channel) symbol;

[0221] For example, transmission resources can be divided independently, such as the first two symbols in a slot;

[0222] In some embodiments, the first information may carry control information for reserving transmission resources for the first information. Optionally, the SCI of the PSCCH carries the reserved resources of the first information, because the data resources can be determined by the first information, and due to contention for access, sensing is not required to determine the reserved resources for the data.

[0223] <3> The transmission resources of PCCH are located in a different resource pool;

[0224] <4> The transmission resources of PSCH are located in a different resource pool;

[0225] Specifically, the physical control channel may include at least one of the physical side link control channel, physical downlink control channel, and physical uplink control channel. The physical shared channel may include at least one of the physical side link shared channel, physical downlink shared channel, and physical uplink shared channel.

[0226] Specifically, the transmission resources can be located in different resource pools than the transmission resources of the PCCH / PSCH.

[0227] In some embodiments, the resource pool of the first information and the data resource pool completely overlap in the time domain, but differ in the frequency domain;

[0228] In some embodiments, the time domains of the resource pool for the first information and the data resource pool do not completely overlap.

[0229] In some embodiments, the offset can be determined according to SFN (System Frame Number) / DFN (Direct Frame Number), rather than according to the logical time slot of the resource pool;

[0230] In some embodiments, the correspondence between WUS signals and transmission resources can be determined based on the resource pool overlap relationship. For example, one WUS signal indicates only the transmission resources preceding the WUS signal in the current overlap and / or at least the next slot; or, for another example, WUS signals within a certain time domain range indicate all second resources within that time domain range.

[0231] <5> The information is determined based on third information, which includes at least one of the following: device identifier (ID), priority, PDB, quality of service (QoS), number of consecutive failed attempts at contention for access, consecutive failure rate of contention for access, number of consecutive successful attempts at contention for access, consecutive success rate of contention for access, and duration of contention for access.

[0232] Specifically, transmission resources can be divided or determined based on at least one of the following: device ID, priority, PDB, QoS, number / rate of (continuous) failures / successes in contention access, and duration of contention access.

[0233] Optionally, after determining, based on the first channel access result, that transmission will be performed on at least one second resource corresponding to the at least one first resource, the first device may perform at least one of the following:

[0234] 1) Determine at least one second resource in the first resource set as either the transmission resource or the reserved resource;

[0235] 2) Determine at least one second resource based on the second channel detection result associated with the first resource set, as the transmission resource or the reserved resource.

[0236] It should be noted that the channel detection result is the result obtained by the first device performing channel detection on the resource. Here, the channel detection specifically detects control information, and the channel detection can also be called sensing detection.

[0237] Optionally, the second channel detection result may include at least one of the detection result obtained by the first device performing channel detection on the first resource set and existing detection results.

[0238] It should be noted that the detection result obtained by the first device performing channel detection on the first resource set can be considered as the detection result within the current detection window range, which at least includes a portion of the second resources in the first resource set. Existing detection results can be understood as the detection results obtained by performing channel detection within at least one detection window range prior to the current detection window range, such as the detection results corresponding to the previous detection window range.

[0239] Specifically, after the first device determines, based on the first channel access result, to perform transmission on at least one second resource corresponding to at least one first resource, if there are many second resources corresponding to the first resource, it needs to select a resource for transmission. To avoid resource conflicts, resource selection can be performed within the second resources based on the sensing detection result. Specifically, at least one second resource can be determined as a transmission resource or a reserved resource from the first resource set, or at least one second resource can be determined as a transmission resource or a reserved resource based on the second channel detection result associated with the first resource set. Since a reserved resource can only be detected if there is transmission within the system, some devices can be allowed to transmit earlier under certain conditions, so that other devices can avoid resource conflicts based on the sensing result.

[0240] In some embodiments, at least one second resource is determined in the first resource set, and the specific implementation of the transmission resource or reserved resource may include at least one of the following:

[0241] 1> Randomly select a second resource;

[0242] 2> Select the second resource based on at least one of the following conditions: priority, PDB, initial retransmission, number of successful access attempts, number of failed access attempts, access success rate, and access duration.

[0243] For example, select the second resource with higher priority or smaller PDB; or, if it is the first transmission, select the second resource that appears earlier in the list.

[0244] Optionally, resource selection can be performed based on the detection results of the first resource set in the past, and the stored perception results can be used to avoid conflicts of the first resource as much as possible.

[0245] In some embodiments, at least one second resource is determined based on the second channel detection result associated with the first resource set. Specific implementations of this as a transmission resource or reserved resource may include at least one of the following:

[0246] 1> Resource selection is performed only based on the detection results of the current first resource set;

[0247] 2> Based on the detection results of the current first resource set and the past first resource sets, perform resource selection;

[0248] 3> When the measured result is greater than a certain threshold, the corresponding second resource is excluded from the second resource set.

[0249] Specifically, the current detection status of the first resource set refers to the detection information obtained when the corresponding detection window is within the first resource set, while the past detection status of the first resource set refers to the detection information obtained before the corresponding detection window was within the first resource set.

[0250] Optionally, the step of determining at least one second resource based on the second channel detection result associated with the first resource set, as the transmission resource or the reserved resource, may include:

[0251] The first device performs channel detection on at least one second resource in the first resource set to obtain a second channel detection result corresponding to the second resource;

[0252] The second resource set is obtained by excluding the second resources whose second channel detection result is greater than the first threshold value from the first resource set;

[0253] At least one second resource is determined from the second resource set as either the transmission resource or the reserved resource;

[0254] The second channel detection result includes at least one of the following: Reference Signal Received Power (RSRP), energy detection result, Received Signal Strength Indication (RSSI), and Signal to Interference Noise Ratio (SINR).

[0255] Specifically, the aforementioned second resource may include at least one of the non-periodic reserved resources and periodic reserved resources reserved by the control information on the detected second resource; the aforementioned excluded second resource may be understood as including all second resources in the entire time slot, or second resources that overlap with the time-frequency domain resources reserved by the control information, without any limitation.

[0256] Optionally, the first threshold value may be associated with at least one of the following:

[0257] 1) The priority of the second resource;

[0258] 2) The PDB of the second resource;

[0259] 3) The second resource performs either initial transmission or retransmission;

[0260] 4) The number of successful access attempts corresponding to the second resource;

[0261] 5) The success rate of competitive access corresponding to the second resource;

[0262] 6) The number of failed access attempts corresponding to the second resource;

[0263] 7) The failure rate of contention for access corresponding to the second resource;

[0264] 8) The success rate of competitive access corresponding to the second resource.

[0265] The auxiliary information-based transmission method provided in this application embodiment can be applied to a second device, which can be a terminal or a network-side device.

[0266] Figure 4 This is a second schematic flowchart of the auxiliary information-based transmission method provided in this application embodiment, as shown below. Figure 4 As shown, the method includes step 401; wherein:

[0267] Step 401: The second device receives first information, which is used to indicate at least one of the following: the first device performs channel access on at least one first resource; the first device performs transmission on at least one second resource; wherein the at least one second resource corresponds to at least one resource for performing channel access.

[0268] Specifically, based on the aforementioned contention access mechanism, the second device may receive first information to instruct the first device to perform channel access on at least one first resource, and / or to instruct the first device to perform transmission on at least one second resource.

[0269] Optionally, after receiving the first information, the second device may also perform at least one of the following:

[0270] Based on the first information, the second device determines whether to perform channel access on the first resource;

[0271] Based on the first information, the second device determines to perform transmission on the at least one second resource;

[0272] Based on the first information, the second device determines to perform reception on the at least one second resource.

[0273] After receiving the first information, the second device falls into one of the following two categories:

[0274] 1) The second device can be a transmitting-side device that performs channel access. In this case, the first information instructs the first device to perform channel access on at least one first resource. The second device can determine whether to perform contention access on the first resource based on the first information, which can effectively mitigate resource conflicts and increase the possibility of contention access.

[0275] 2) The second device can also be a receiving device for performing transmission, specifically a receiving device for receiving data. In this case, the first information can instruct the first device to perform channel access on at least one first resource. The second device can determine at least one second resource to perform transmission based on the at least one first resource for performing channel access. The first information can also directly instruct the first device to perform transmission on at least one second resource to assist the second device in performing transmission on at least one second resource. This can effectively reduce the number of resources for the second device to detect and control information, thereby reducing the energy consumption of the device.

[0276] In this embodiment, the second device receives first information to instruct at least one of the following: the first device performs channel access on at least one first resource; the first device performs transmission on at least one second resource. The first information can assist the second device in determining whether to perform contention-based access on the first resource, mitigating resource conflicts during contention-based access; or, the first information can assist the second device (receiving device) in determining the second resource for transmission, filtering out resources that do not participate in transmission, eliminating the need for detection and control information on resources that do not participate in transmission, thereby reducing terminal power consumption to some extent.

[0277] Optionally, the second device, based on the first information, may determine whether to perform channel access on the first resource in the following ways:

[0278] If the first condition is met, the second device will not perform channel access on the first resource corresponding to the first information;

[0279] The first condition includes at least one of the following:

[0280] 1) The third channel access result of the second device on the first resource is greater than the second threshold value; wherein, the third channel access result includes at least one of the following: RSRP, energy detection result, RSSI and SINR;

[0281] Specifically, the aforementioned third channel access result can be obtained by measuring the sequence or reference signal associated with the first information.

[0282] In some embodiments, the second threshold value may be predefined by the protocol, preconfigured by the network side, or configured by the network side.

[0283] In some embodiments, the second threshold value may be related to at least one of the following: transmission priority, reception priority, PDB, QoS, number / rate of contention access (continuous) failures / successes, and contention access duration.

[0284] 2) The priority of the second device in performing channel access on the first resource is lower than the priority of the first device in performing channel access on the first resource;

[0285] 3) The number of times the second device fails to compete for access on the first resource is less than the third threshold value;

[0286] 4) The number of consecutive times the second device fails to compete for access on the first resource is less than the fourth threshold value;

[0287] 5) The failure rate of the second device in contention for access on the first resource is less than the fifth threshold value;

[0288] 6) The number of times the second device successfully competes for access on the first resource is greater than or equal to the sixth threshold value;

[0289] 7) The number of consecutive times the second device successfully competes for access on the first resource is greater than or equal to the seventh threshold value;

[0290] 8) The success rate of the second device in competing for access on the first resource is greater than or equal to the eighth threshold value;

[0291] 9) The duration of contention for access to the second device on the first resource is greater than the ninth threshold.

[0292] It's understandable that when the second device experiences fewer access failures, it can prioritize allowing the first device to access the channel, thus improving system efficiency. However, if the number of access failures is high, it might be better not to prioritize the first device's channel access. Conversely, if the second device experiences many access failures, it's also advisable to prioritize the first device's channel access, as not prioritizing it would lead to resource conflicts, reducing transmission reliability and negatively impacting the second device's transmission. Therefore, it's important to note that the "greater than the threshold" mentioned in sections 2)-9) above can also be interpreted as "less than the threshold," or vice versa.

[0293] It should be noted that the second, third, fourth, fifth, sixth, seventh, eighth, and ninth thresholds can be set according to the actual situation. They can be predefined by the protocol, pre-configured by the network side, or configured by the network side. No restrictions are imposed here.

[0294] Optionally, the second device may receive second information; wherein the second information is used to indicate at least one of the following: the first device performs transmission on at least one transmission resource in the first resource set; the first device performs transmission on at least one reserved resource in the first resource set; time-frequency domain location information of the transmission resource; time-frequency domain location information of the reserved resource; second device identification information for indicating the identifier of the device performing the transmission; third device identification information for indicating the identifier of the receiving device; and second priority information for indicating the priority of the first device performing transmission on the second resource; wherein the first resource set includes at least one second resource;

[0295] Based on the second information, the second device selects at least one second resource from the first resource set as at least one of the transmission resource and the reserved resource.

[0296] Specifically, the second device can receive second information sent by the first device after successful contention for access, to assist the second device in selecting at least one of the second resources in the first resource set as a transmission resource and a reserved resource for transmission. Specifically, at this time, the second device only performs control channel detection on the second resource indicated by the first information. If the first information is not associated with a specific time-frequency domain resource location, the second device needs to detect possible control information locations in all subchannels in the time domain indicated by the first information; otherwise, it detects possible control information locations in the time-frequency domain location indicated by the first information.

[0297] Optionally, if the priority of the first information received from another device is higher than the priority of the first information received from the first device, the second device may not perform the receiving operation, because it is assumed that the first device will fail to compete for access and therefore will not receive any data sent to it.

[0298] Optionally, the second information may be carried in at least one of the following:

[0299] 1) Preamble;

[0300] 2) Control information;

[0301] 3) Data information.

[0302] Optionally, when the second device does not detect data transmitted to the second device on at least one of the second resources indicated by the first information, it performs at least one of the following:

[0303] 1) Stop performing channel detection;

[0304] 2) Upon receiving the first message instructing the transmission to the second device, perform channel detection;

[0305] Specifically, when the second device does not detect data transmitted to it, it will not perform channel detection until it receives the next first information indicating that data has been sent to it. That is, the first information can be a single indication. Since receiving requires detecting the WUS signal first, the contention for access between the two transmitting ends requires a certain time interval.

[0306] 3) Perform channel detection at time units T2 after the current time unit; where T2 is greater than 0; wherein the time unit includes at least one of the following: symbol, time slot, sub-time slot, frame, subframe, microsecond, millisecond, and second.

[0307] Specifically, if the second device does not detect data transmitted to the second device, it can continue to perform detection over the subsequent T2 time units. This may correspond to the situation where the first information is associated with multiple second resources. In this case, the sending device may also exclude multiple second resources when determining the second resource based on the reception of one first information.

[0308] 4) Perform channel detection after an interval of T3 time units from the current time unit; where T3 is greater than 0;

[0309] Specifically, if the second device does not detect data transmitted to the second device, it can perform the detection again after an interval of time K, for example, after an interval of T3 time units from the current time unit. This is a rollback mechanism, which is theoretically the same as indicating multiple resources, similar to implicitly indicating multiple resources.

[0310] 5) Based on the time-frequency domain resource location information corresponding to the next second resource indicated by the first information, perform channel detection;

[0311] Specifically, when the second device does not detect data transmitted to the second device, it can perform detection at the next time-frequency domain resource location indicated by the first information, corresponding to multiple indicated resources or the case of a time pattern.

[0312] Optionally, the second device, based on the first information, determines the implementation method for receiving on the at least one second resource, which may include:

[0313] The second device detects control information on at least one second resource corresponding to the first information based on the first information, and determines to receive data on the at least one second resource according to the control information.

[0314] Optionally, the second device, based on the first information, determines the implementation method for performing transmission on the at least one second resource, which may include:

[0315] Based on the first information, the second device excludes second resources that meet the second condition from the first resource set to obtain a third resource set;

[0316] The second device identifies at least one second resource in the third resource set as a transmission resource or a reserved resource;

[0317] The second device transmits data on at least one of the transmission resources and the reserved resources;

[0318] The second condition includes at least one of the following:

[0319] 1) The fourth channel detection result of the second device on the second resource is greater than the tenth threshold; wherein, the fourth channel detection result includes at least one of the following: RSRP, energy detection result, RSSI, and SINR;

[0320] 2) The priority of the second device performing transmission on the second resource is lower than the priority of the first device performing transmission on the second resource;

[0321] 3) The number of times the second device fails to transmit on the second resource exceeds the eleventh threshold;

[0322] 4) The number of consecutive transmission failures of the second device on the second resource exceeds the twelfth threshold;

[0323] 5) The transmission failure rate of the second device on the second resource is greater than the thirteenth threshold;

[0326] 8) The transmission success rate of the second device on the second resource is less than or equal to the sixteenth threshold;

[0327] 9) The transmission duration of the second device on the second resource is greater than the seventeenth threshold.

[0328] Specifically, the second device can exclude a portion of the second resources indicated by the first information from the first resource set, specifically excluding the second resources associated with the first information that meet the second condition, and then select at least one of the transmission resources and reserved resources from the remaining second resources in the first resource set for transmission, specifically for sending data through the transmission resources and reserved resources.

[0329] It should be noted that the tenth, eleventh, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, and seventeenth thresholds can be set according to actual conditions. They can be predefined by the protocol, preconfigured by the network side, or configured by the network side, and no restrictions are imposed here.

[0362] Figure 5 This is one of the signaling interaction diagrams of the transmission method based on auxiliary information provided in the embodiments of this application, such as... Figure 5 As shown, the method includes steps 501 and 502; wherein:

[0363] Step 501: The first device sends first information to the second device, the first information being used to instruct the first device to perform channel access on at least one first resource;

[0364] Step 502: The second device determines whether to perform channel access on the first resource based on the first information.

[0365] Figure 6 This is the second signaling interaction diagram of the transmission method based on auxiliary information provided in the embodiments of this application, as shown below. Figure 6 As shown, the method includes steps 601 and 602; wherein:

[0366] Step 601: The first device sends first information to the second device, the first information being used for at least one of the following: the first device performs channel access on at least one first resource; the first device performs transmission on at least one second resource;

[0367] Step 602: The second device determines, based on the first information, to perform reception on at least one second resource.

[0368] The following example illustrates the auxiliary information-based transmission method provided in the embodiments of this application.

[0369] (I) Example 1: Assisted Access Assistance (WUS) for Contention;

[0370] While contention-based access can mitigate some conflicts through access mechanism design, resource conflicts still exist when there are a large number of devices due to limited starting points for contention-based access and half-duplex mechanisms. Therefore, it is advisable to send auxiliary information (i.e., the first information in this application) in advance, allowing devices intending to transmit to avoid some resource conflicts by assessing the auxiliary information.

[0371] 1) The auxiliary information carries only one contention access indication. In this case, the device avoids conflicts in advance and increases the success rate of channel access by selecting the first resource with no corresponding indication or with fewer indications.

[0372] 2) Auxiliary information carries priority information. In this case, the device can exclude resources indicated by auxiliary information with a higher priority than itself, and ignore indications with a lower priority than itself.

[0373] 3) The auxiliary information carries the associated location of the first resource (i.e., the time-frequency domain location of the first resource), and the auxiliary receiving device selects the first resource or the second resource.

[0374] As mentioned above, by judging auxiliary information, the device can avoid some resource conflicts in advance. This requires the device to select either a first resource or a second resource based on the auxiliary information. Therefore, it is necessary to determine under what conditions the device will exclude resources associated with the auxiliary information. Specific examples are as follows:

[0375] 1> Once auxiliary information is detected, its associated resources are excluded;

[0376] 2. When certain conditions are met, exclude its associated resources. These conditions may include at least one of the following:

[0377] a) The first measured value is greater than the first threshold;

[0378] Optionally, the first measurement value can be a sequence associated with the measurement of the first information, a reference signal, or a value obtained by directly measuring energy.

[0379] Optionally, the first measurement can be a measurement of at least one of energy, RSSI, RSRP, RSRQ, and SINR.

[0380] Optionally, the first threshold is predefined by the protocol, preconfigured by the network side, or configured by the network side.

[0381] Optionally, the first threshold is related to at least one of the following: transmit priority, receive priority, PDB, QoS, number / rate of (continuous) failures / successes in contention access, and duration of contention access.

[0382] b) The priority of the first information association is higher than the priority of the second device sending the association;

[0383] c) The number / rate of consecutive failed / successful access attempts or the duration of access attempts exceeds the second threshold.

[0384] (ii) Example 2: Enhancement method for WUS (Warning Information) indication but no successful access contention;

[0385] When a device sends auxiliary information that explicitly indicates which resources might experience contention for access and thus transmission, the receiving device will perform reception on the corresponding resources based on the auxiliary information, thus saving reception energy. However, since contention for access may fail, the receiving device may not be able to detect data at the corresponding resource location, resulting in wasted energy. Therefore, the following methods can be considered to address this issue:

[0386] 1) It is believed that this situation is unavoidable;

[0387] 1> The device continues to sleep until it receives the next WUS indication, i.e., a single indication; since WUS needs to be detected, there is a certain time interval between two contention access attempts.

[0388] 2> Continue monitoring for a period of time;

[0389] Specifically, the UE may continue to attempt access in subsequent slots, so we can continue to listen for a period of time.

[0390] Optionally, the duration of the maintenance can be determined based on WUS after excluding multiple slots. The number of slots can be determined based on CR (Channel Occupancy Ratio) / CBR (Channel Busy Ratio), etc. In this case, the energy-saving effect may be limited, and WUS can only be used to reduce reception, making it difficult to improve the success rate of access.

[0391] 3> After a certain backoff value, open the receiving window;

[0392] Specifically, collisions can be randomized by randomly setting a backoff value for reopening the receiving window for different devices that have not detected data. This backoff value is a random value greater than a certain threshold to mitigate contention-based access conflicts. From an energy-saving perspective, the backoff value can be a pre-configured value to facilitate alignment between the transmitting and receiving parties.

[0393] 2) Enhanced WUS indication;

[0394] 1>WUS indicates multiple reserved locations;

[0395] Specifically, the reserved space can be used for initial transmission, retransmission, and transmission of other processes.

[0396] Alternatively, multiple WUS can refer to the same resource, or multiple WUS can refer to multiple different resources.

[0397] For example, WUS indicates a PSCCH / PSSCH, but PSCCH / PSSCH channel contention is not guaranteed to succeed. Therefore, multiple PSCCH / PSSCH occasions within the WUS associated time window can be considered. TX (Transmission) UEs can attempt access on multiple PSCCH / PSSCH occasions, while RX (Reception) UEs perform blind checks on multiple PSCCH / PSSCHs associated with WUS until the corresponding PSCCH / PSSCH is detected or all associated PSCCH / PSSCHs are blindly checked.

[0398] 2>WUS indicates the pattern;

[0399] Specifically, multiple patterns can be randomly collided, similar to the understanding of collision randomization mentioned above, which will not be elaborated here.

[0400] Optionally, the number of resources corresponding to a pattern can be different, depending on factors such as congestion.

[0401] 3>WUS indicates priority;

[0402] Specifically, the receiving device can determine whether to wake up by comparing priorities and perform control channel detection. Priority can be directly indicated in the WUS signal, and different priorities can be represented by length, such as 2 or 4. Different symbol lengths represent different priorities.

[0403] For example, different priorities can be represented by position, with higher priority transmission positions in a slot; or priorities can be distinguished by frequency domain, if there is no frequency domain mapping.

[0404] For example, under a fixed mapping relationship, if a WUS signal has been sent beforehand, then no WUS signal will be sent.

[0405] For example, different priorities can be determined based on the sequence (if an ID cannot be carried).

[0406] 4> The WUS signal is divided into two stages: first, priority and ID information are sent, and finally, an indication is sent.

[0407] 3) Enhanced contention for access;

[0408] 1> Cancel sending mechanism;

[0409] Specifically, the transmitting device can determine in advance whether to cancel the transmission based on the WUS reception, and can provide feedback through channels such as the PSFCH channel.

[0410] 2> Dual confirmation mechanism;

[0411] For example, receiving two WUS requests is required to confirm receipt.

[0412] The above design can further reduce the possibility of resource conflicts, improve the success rate of competitive access, and help the equipment to save energy.

[0413] (III) Example 3: Assisted reception using WUS (Wireless Information Support)

[0414] Since the receiving device needs to decode control information to determine if data has been sent to it, it needs to perform blind detection of the control information as much as possible to avoid missing any data, which leads to high energy consumption. To reduce the energy consumption of reception, auxiliary information can be used, that is, the device only performs blind detection on the time-frequency domain resources indicated by the auxiliary information, thereby greatly reducing the related energy consumption.

[0415] (iv) Example 4: Assistance Information (WUS) assists in resource reservation in the first resource set;

[0416] When a primary resource corresponds to multiple secondary resources, after a device successfully accesses the network, it needs to select which secondary resources to transmit on. Considering that multiple devices may successfully access the network simultaneously, it is advisable to send auxiliary information in advance indicating at least one of its own transmission resources and reserved resources to help other devices avoid resource conflicts.

[0417] If all terminals need to detect auxiliary information before determining transmission resources, it may result in no data transmission on the second resources that are earlier in the time domain. Therefore, it is advisable to set certain conditions. If the conditions are met, transmission can proceed directly. If the conditions are not met, auxiliary information can be sent first, or auxiliary information from other devices can be detected first before determining which second resources to transmit on. The above conditions include at least one of the following:

[0418] 1) Is the priority greater than the threshold?

[0419] 2) Is the PDB less than the threshold?

[0420] 3) Is there any testing information?

[0421] 4) Whether the number / rate / duration of consecutive failed / successful access attempts exceeds the threshold.

[0422] When determining the second resource, the device's behavior satisfies at least one of the following:

[0423] 1) The resource selection window range is the first resource set (the set of second resources corresponding to the first resource that successfully competes for access), that is, the candidate resource set is initialized as the first resource set;

[0424] 2) The detection window for auxiliary information is the first resource set;

[0425] 3) When the conditions are met, the terminal randomly selects at least one of the resources in the first resource set as the transmission resource and the reserved resource;

[0426] Optionally, sending auxiliary information may directly indicate at least one of the transmission resources and reserved resources.

[0427] 4) When the conditions are not met, the terminal determines at least one of the transmission resources and reserved resources based on the auxiliary information.

[0428] Optionally, the terminal excludes resources from the first resource set that satisfy at least one of the following:

[0429] 1> The measurement result is greater than the threshold;

[0430] 2> Priority higher than the threshold, or higher than its own sending threshold;

[0431] 3> PDB is less than the threshold;

[0432] 4> The number of consecutive failed / successful access attempts / rate / duration exceeds the threshold.

[0433] Optionally, the terminal performs the resource selection process after a certain interval following the reference time:

[0434] The reference time can be the starting resource position of the first resource set or the Ath resource position. The interval time can be predefined by the protocol, preconfigured by the network side, or configured by the network side, and is related to priority, PDB, number / rate / duration of contention access (continuous) failures / successes, etc.

[0435] (V) Example 5: Design method for auxiliary information (WUS) indication;

[0436] To achieve the aforementioned multiple auxiliary functions, the design of auxiliary information involves the following aspects:

[0437] 1) Indicator particle size;

[0438] 2) Resource allocation;

[0439] 3) Mapping relationship;

[0440] 4) Resource reservation method.

[0441] Regarding the indicator granularity, consider the following two possibilities:

[0442] 1>slot; 2>subchannel.

[0443] Regarding resource allocation, one possibility is that auxiliary information is located in an independent resource pool, and another is that it is located in a shared resource pool. If it is an independent resource pool, it could be a resource pool with completely overlapping time domains, a frequency domain FDM (Frequency Division Multiplexing) resource pool, a TDM (Time Division Multiplexing) resource pool, or an irregular resource pool. Different resource allocation methods may affect the mapping relationship.

[0444] (i) If the resource pools are independent and have completely overlapping time domains, the mapping relationship is as follows:

[0445] 1) A fixed mapping relationship can reduce the information carried by the WUS signal. For example, for the WUS at time n, slot n+k can be reserved;

[0446] 2) Directly indicate the pattern;

[0447] Specifically, a pattern can include different reservation counts and different reservation intervals. This needs to be indicated by the pattern. Resources indicated by different patterns can or cannot overlap.

[0448] In some embodiments, WUS signals from different locations may indicate the same resource;

[0449] 3) Direct instructions;

[0450] Specifically, if the slots have the same index, it can be indicated directly.

[0451] (ii) If it is an irregular, independent resource pool, then it is necessary to consider how to establish a mapping relationship:

[0452] 1) Establish a virtual resource pool: For example, if the virtual resource pool contains contiguous resources, renumber them;

[0453] 2) Ignore resource pools and use SFN / DFN+slot numbering;

[0454] 3) Logic time slot offset; for example, the time interval between the WUS signal and the first or second resource is determined by a fixed logic time slot offset.

[0455] 4) Determine the correspondence between WUS signals and transmission resources based on the resource pool overlap relationship.

[0456] For example, a single WUS signal indicates only the current overlap, and / or, at least the transmission resources preceding the WUS signal in the next slot;

[0457] For example, a WUS signal within a certain time domain indicates all transmission resources within that time domain.

[0458] (iii) Under an independent resource pool, the resource reservation for auxiliary information satisfies at least one of the following:

[0459] 1) Reserved resources for WUS resources (i.e., the second resource mentioned above);

[0460] Optionally, the temporal length of the WUS resource can be displayed; for example, through dynamic reservation, specifically through SCI reservation, which is only used as a placeholder and can be used with a Preamble, which has a corresponding reservation mapping relationship.

[0461] It should be noted that dynamic reservation needs to determine whether there is an independent resource allocation, such as the first two symbols of each slot, the scope of reservation, and the granularity may be symbols.

[0462] Optionally, one or more resources can be reserved.

[0463] 2) Preemptively send;

[0464] Specifically, no reservation is required; transmission is preempted according to the corresponding priority.

[0465] 3) Fixed division;

[0466] Specifically, resource pool regions can be divided based on information such as ID, time domain length, and priority.

[0467] (iv) If it is a shared resource pool, the determination and reservation of auxiliary information resources shall meet at least one of the following:

[0468] 1) Pre-allocation;

[0469] For example, the PSFCH channel can be used, but it can only be used as a placeholder; another example is an additional channel and a fixed position, such as before the PSFCH.

[0470] 2) Resource reservation: It is more suitable for non-fixed instructions, or when WUS resources and data resources have a constant relative relationship.

[0471] Sending WUS resources is similar to the reservation method for existing data transmission. Resources are reserved through chain reservation, which carries control information for reservation.

[0472] The reservation in SCI can be indicated for WUS resources, for example, a 2-3 bit indication.

[0473] 3) Resource grabbing.

[0474] (vi) Example 6: Contention access is the same as the existing channel access mechanism;

[0475] Contention-based access requires channel detection to determine whether the channel meets the access conditions. Channel access mechanisms in unlicensed frequency bands can be reused as much as possible, as follows:

[0476] 1. Type 1: Backoff-based channel access mechanism. The terminal considers contention-based access successful when the counter is 0 and the channel detection is empty. The counter adjustment procedure is as follows:

[0477] Step 1: Initialize the counter to N, which is a random value between 0 and the preset value (contention window) CW;

[0478] Step 2: If N is greater than 0, decrement the counter N by 1;

[0479] Step 3: Detect the channel within the first preset time length. If the detection is empty, proceed to step 4; otherwise, proceed to step 5.

[0480] Step 4: If N is 0, stop this process; otherwise, go to step 2.

[0481] Step 5: Detect the channel within the second preset time period;

[0482] Step 6: If the channel detection is empty within the second preset time period, jump to step 4; otherwise, jump to step 5.

[0483] 2. Type 2: One-shot channel access mechanism;

[0484] Specifically, the channel is detected within a third preset time period. If the channel is empty, it is considered that the contention for access has been successful; otherwise, it is considered that the access has failed.

[0485] Optionally, the first preset time length, the second preset time length, the third preset time length, CW, and the detection threshold are predefined by the protocol, preconfigured by the network side, or configured by the network side.

[0486] (vii) Example 7: The difference between contention-based access and existing channel access mechanisms;

[0487] Unlike existing channel access mechanisms in unlicensed frequency bands, the parameters, detection methods, detection objects, and starting positions of the contention access mechanism may differ. In addition, the first resource used for contention access may not be contiguous with the second resource used for transmission after access.

[0488] Other possible differences are that the channel access mechanism in unlicensed bands is based on channels (20MHz). Once access is successful, the device can perform transmissions within the channel under certain restrictions. In contrast, the unit of the contention access mechanism may be one of REG (Resource Group), RB (Resource Block), RBG (Resource Block Group), subchannel, subchannel group, channel, or RBset. Furthermore, the first resource allocated for contention access does not necessarily have to be greater than the second resource allocated for transmission; for example, the first resource might be one subchannel, while the second resource might be five subchannels or an entire time slot.

[0489] In addition, to avoid the impact of half-duplex, competitive access requires multiple starting positions, or multiple primary resources. Figure 7 This is a schematic diagram of the first resource in the auxiliary information-based transmission method provided in the embodiments of this application, as shown below. Figure 7 As shown, within the gap symbol of a slot, there are four starting positions. A device selects one starting position for channel access based on certain conditions. When the channel access duration reaches a predetermined time, if the detection is empty, it is considered a successful contention for access, and transmission proceeds in subsequent slots. For example, a device selecting subchannel 0 or subchannel 1 chooses the first starting position for detection. The detection is empty, therefore the contention for access is successful. After successful detection, it sends a signal at a subsequent detection position corresponding to the same second or first resource set, or on the first resource, allowing other lower-priority devices to detect it, thus avoiding resource conflicts. The judgment conditions may include at least one of the following: priority, PDB (Program Data Base), retransmission, number of successful contention for access, number of failed contention for access, contention for access success rate, and contention for access duration. For instance, a higher-priority device chooses an earlier starting position. After successful detection, it sends a signal at subsequent detection positions, allowing other lower-priority devices to detect it, thus avoiding successful contention for access in that slot.

[0490] (viii) Example 8: The relationship between the first resource and the second resource;

[0491] Unlike channel access mechanisms in unlicensed frequency bands, in a contention-based access mechanism, the first resource for contention-based access and the second resource for transmission are not necessarily consecutive.

[0492] 1) The primary and secondary resources are continuous;

[0493] For example, the first resource is located within the gap symbol, such as... Figure 7 As shown.

[0494] For example, the first resource may be located in a separate frequency domain (e.g., an independent resource pool), and may only be continuous in the time domain. Figure 8 This is one of the schematic diagrams illustrating the relationship between the first resource and the second resource in the auxiliary information-based transmission method provided in this application embodiment, such as... Figure 8 As shown.

[0495] 2) The primary and secondary resources are discontinuous;

[0496] For example, the starting positions of the first resource and the second resource are spaced G time units apart. Figure 9 This is the second schematic diagram illustrating the relationship between the first resource and the second resource in the auxiliary information-based transmission method provided in this application embodiment, as shown below. Figure 9As shown, for example, to allow time for sending additional instructions, the first resource and the second resource cannot be consecutive.

[0497] Optionally, the time unit may be symbol, slot, mini-slot, subframe, frame, us, ms, or s.

[0498] Meanwhile, the granularity of the first resource and the granularity of the second resource may be different.

[0499] 1) A primary resource corresponds to B secondary resources;

[0500] a>as Figure 7 As shown, four first resources correspond to one second resource; as Figure 8 As shown, there are 5 primary resources and 2 secondary resources.

[0501] b) The frequency domain size of the first resource may be the same as that of the second resource, such as... Figure 7 As shown, they all represent one subchannel; however, they may differ, such as... Figure 8 As shown, the first resource is one subchannel or several RBs, while the second resource is two subchannels.

[0502] Optionally, A and B are positive integers, which are predefined by the protocol, preconfigured by the network side, or configured by the network side.

[0503] (ix) Example 9: Resource selection after successful competitive access;

[0504] When there are multiple second resources corresponding to the first resource, the terminal can randomly select at least one of the second resources as a transmission resource and a reserved resource. However, random selection may still cause resource conflicts between terminals that successfully compete for the same resource simultaneously. Therefore, resource selection based on perception can be considered for these second resources.

[0505] When determining transmission resources, the device's behavior satisfies at least one of the following:

[0506] 1) The resource selection window range is the first resource set (the set of second resources corresponding to the first resource that successfully competes for access), that is, the candidate resource set is initialized as the first resource set;

[0507] 2) The detection window range is the slot containing the first resource set and / or existing detection results;

[0508] 3) The terminal determines at least one of the transmission resources and reserved resources based on sensing;

[0509] Optionally, the terminal excludes candidate resources from the candidate resource set that satisfy at least one of the following conditions:

[0510] 1> The measurement result is greater than the threshold;

[0511] 2> Priority higher than the threshold, or higher than its own sending threshold;

[0512] 3> PDB is less than the threshold;

[0513] 4> The number of consecutive failed / successful access attempts / rate / duration exceeds the threshold.

[0514] In this embodiment of the application, by introducing auxiliary information (i.e., the first information in this application) in advance, the probability of resource conflict can be reduced, and the power consumption of the terminal can also be reduced.

[0515] The auxiliary information-based transmission method provided in this application can be executed by an auxiliary information-based transmission device. This application uses an auxiliary information-based transmission device executing the auxiliary information-based transmission method as an example to illustrate the auxiliary information-based transmission device provided in this application.

[0516] Figure 10 This is one of the structural schematic diagrams of the auxiliary information transmission device provided in the embodiments of this application, such as... Figure 10 As shown, the auxiliary information-based transmission device 1000, applied to the first device, includes:

[0517] Sending module 1001 is configured to: send first information, the first information being used to indicate at least one of the following:

[0518] The first device performs channel access on at least one first resource;

[0519] The first device performs a transmission on at least one second resource;

[0520] Wherein, the at least one second resource corresponds to at least one resource for performing channel access.

[0521] In the auxiliary information-based transmission apparatus provided in this application embodiment, the transmitting module of the first device transmits first information to instruct at least one of the following: the first device performs channel access on at least one first resource; the first device performs transmission on at least one second resource. The first information can assist other devices in determining whether to perform contention-based access on the first resource, mitigating resource conflicts when devices perform contention-based access; or, the first information can assist the receiving device in determining the second resource for transmission, filtering out resources that do not participate in transmission, eliminating the need to detect control information on resources that do not participate in transmission, and thus reducing terminal power consumption to a certain extent.

[0522] Optionally, the sending module 1001 is specifically used to send the first information before performing channel access.

[0523] Optionally, the transmission device 1000 based on auxiliary information further includes:

[0524] The first processing module is configured to determine, based on the channel access status of the first device on the at least one first resource, whether to perform transmission on at least one second resource corresponding to the at least one first resource.

[0525] Optionally, the first processing module is also used for:

[0526] Perform channel access on at least one first resource to obtain a first channel access result;

[0527] Based on the first channel access result, if it is determined that transmission is to be performed on at least one second resource corresponding to at least one first resource, then the second information is sent.

[0528] The second information is used to indicate at least one of the following:

[0529] The first device performs transmission on at least one transmission resource in the first resource set;

[0530] The first device performs the transmission on at least one reserved resource in the first resource set;

[0531] The time-frequency domain location information of the transmission resources;

[0532] The time-frequency domain location information of the reserved resources;

[0533] The second device identification information is used to indicate the identifier of the device performing the transmission;
