If the name of the core network device mentioned in the embodiments of the present application changes in the subsequent protocol version (for example, 6G), it is also within the protection scope of the present application.

[0061] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices together, and the embodiments of the present application do not make specific limitations thereto. It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a dedicated hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0062] The first device 13 can be an Internet of Things device. The Internet of Things device can be an Ambient Internet of Things (A-IoT) device, an A-IoT terminal, a Passive-IoT device, an Ambient Power (AMP) device, a zero-power device, a zero-power terminal, a responding device, a low-power IoT device, an IoT device, a tag, a Radio Frequency Identification (RFID) tag, and the like. An exemplary device communicating with the Internet of Things device can be referred to as a reading and writing device. For example, the reading and writing device can be the terminal 11 or one module in the terminal 11. For another example, the reading and writing device can be the network side device 12 or one module in the network side device 12.

[0063] Optionally, the device communicating with the Internet of Things device includes but is not limited to at least one of the following:

[0064] The reading and writing device, the reader, the terminal, the relay device, the auxiliary node, the repeater, the access network device (such as a base station or a TRP), the core network device, the device providing a carrier wave or a continuous wave.

[0065] The carrier wave or the continuous wave is used to provide energy for the Internet of Things device, or the carrier wave or the continuous wave is used for the Internet of Things device to perform backscattering. For better understanding, the following explains and describes the related concepts and technologies that can be involved in the embodiments of the present application.

[0066] In the related art, in the 3GPP R19 AIoT study, the AIoT device is characterized according to the energy storage capacity of the Ambient Internet of Things device and the ability to generate a radio frequency signal for transmission. The AIoT device has the following types:

[0067] 1) Device A: no energy storage, no independent signal generation / amplification, i.e., backscattering transmission.

[0068] 2) Device B: with energy storage, no independent signal generation, i.e. backscatter transmission. The use of stored energy can include amplification of the reflected signal.

[0069] 3) Device C: with energy storage, with independent signal generation, i.e. active RF components for transmission.

[0070] Different energy storage capabilities of devices also affect the transmission quality of the devices. In general, devices with higher energy storage also mean higher reception sensitivity, or higher transmission power, and the reliability of the reception or transmission link can be better guaranteed.

[0071] Main data / service types of AIoT:

[0072] Device-originated (DO);

[0073] Device-terminated (DT).

[0074] Among them, DO and DT data represent that the data flow originates from or is transmitted to the A-IoT device (similar to a Radio Frequency Identification (RFID) tag). For data flow originating from the A-IoT device, i.e. DO data, it can be further classified as:

[0075] DO-A: DO autonomous, i.e. AIoT device autonomously initiates data transmission;

[0076] For example: connecting a large number of various sensors, which collect and actively report information about the environment, equipment and living things when necessary.

[0077] DO-DTT, DO device-terminated triggered, i.e. a base station or other reader device triggers the AIoT device to initiate data transmission;

[0078] For example: asset identification, status reporting and tracking, the reader collects data from the tag by triggering the inventory program. Since the data is generated / initiated in the IoT device, this service should be considered as a DO service initiated by the tag triggered by the Reader-side control command.

[0079] Some terms of A-IoT:

[0080] A-IoT R2D: Reader-to-Device, i.e. reader to device;

[0081] A-IoT D2R: Device-to-Reader, i.e., device to reader;

[0082] R2D transmission: R2D transmission;

[0083] D2R transmission: D2R transmission;

[0084] PRDCH (Physical R2D Channel): i.e., channel carrying R2D transmission;

[0085] PDRCH (Physical D2R Channel): i.e., channel carrying D2R transmission.

[0086] Deployment scenarios of A-IoT:

[0087] A-IoT can have multiple deployment scenarios, two of which are introduced below.

[0088] Scenario one (or referred to as topology one):

[0089] A-IoT base station (BS) and A-IoT device directly communicate, and perform A-IoT data and signaling transmission. Among them, the base station sending A-IoT R2D signal and the base station receiving A-IoT D2R signal can be the same or different.

[0090] Scenario two (or referred to as topology two):

[0091] AIoT BS communicates with A-IoT device through an intermediate node. The intermediate node can be a UE, a repeater, a relay, an IAB node, etc.

[0092] The BS can control the intermediate node through air interface signaling or other interfaces, for example, the BS controls the UE through the air interface of NR Uu.

[0093] NR supports segmented transmission for data transmission over Uu interface. According to the current protocol, the Medium Access Control (MAC) layer determines the size of the transport block according to the available resource amount and the physical layer transmission parameters (such as Modulation and coding scheme (MCS), the number of Multiple-Input Multiple-Output (MIMO) streams, etc.), and then determines the amount of data that each logical channel (Logical Channel, LCH) can transmit in the current transport block according to the size of the transport block and the logical channel prioritization (Logical Channel Prioritization, LCP parameter) of each logical channel (such as LCH priority, Bj). According to the amount of data that each LCH can transmit in the current transport block, the MAC layer requests data from the Radio Link Control (RLC) layer corresponding to each LCH. For an LCH, when the amount of data requested by the MAC layer from the corresponding RLC layer cannot completely accommodate an integer number of RLC Protocol Data Units (PDUs), the RLC layer will split the RLC Service Data Unit (SDU) to generate at least one RLC PDU carrying a segment of the RLC SDU, so that one or more RLC PDUs submitted by the RLC layer to the MAC layer can match the amount of data requested by the MAC layer. When generating a segment carrying an RLC SDU, the RLC layer will indicate the segment information in the RLC layer protocol header, including the representation of the corresponding RLC SDU, the segment identifier, the position information of the segment in the corresponding RLC SDU, the length information, etc. Using these information, when the receiving end RLC layer collects all segments of an RLC SDU, based on the indication information carried in the RLC protocol header of the RLC PDU carrying each segment, the RLC SDU is recovered.

[0094] Three types of segmentation are currently discussed in AIOT:

[0095] 1. Similar to the segmentation of NR, a message is split into multiple segments at a high layer such as a MAC layer, and transmitted by the underlying layer respectively. For example, the high layer splits the message into multiple MAC PDUs, and the physical layer transmits the corresponding Transport Blocks (TBs) individually. The physical layer transmission mechanisms (such as encoding) of these transmissions can be controlled separately.

[0096] 2. Another is the segmentation of the physical layer, as shown in FIG. 1b, for example, a transmission time is too long, due to the sending end or the receiving end of the ability problem, may not rely on the preamble to maintain or obtain accurate time-frequency synchronization, the need to rely on the midamble in the transmission to assist in synchronization. These midamble will be divided into multiple segments. Different segments can be unified CRC, or individual CRC, or partially shared CRC, partially individual CRC, and partially without CRC, which is not limited at present.

[0097] 3. Application layer segmentation, similar to RFID, read and write commands, can read or write to a certain memory, from a certain address / bit / text, X (X = 8 or 16) bits or words.

[0098] At present, for scenario two, the base station cannot necessarily know the specific situation of the AIoT device in time, so as to guarantee effective resource management. For this purpose, the present application provides an information transmission method.

[0099] The information transmission method and device provided by the embodiments of the present application and related devices will be described in detail in combination with the drawings and some embodiments and application scenarios.

[0100] Please refer to FIG. 2, which is a flowchart of an information transmission method provided by an embodiment of the present application, the method being applied to a terminal. As shown in FIG. 2, the method comprises the following steps:

[0101] Step 201, the terminal acquires auxiliary information, the auxiliary information being associated with a target situation, the target situation being related to R2D transmission and / or D2R transmission.

[0102] Optionally, the terminal acquiring auxiliary information can be that the terminal receives auxiliary information, for example, auxiliary information sent by an AIoT device; or the terminal can determine auxiliary information, for example, the terminal determines auxiliary information based on transmission between the terminal and the AIoT device.

[0103] In the embodiments of the present application, the auxiliary information is associated with a target situation, the target situation being related to R2D transmission and / or D2R transmission, that is, the auxiliary information can be used to represent or indicate or describe the transmission situation or state between R2D transmission and / or D2R transmission. For example, the auxiliary information can be used to represent whether R2D transmission and / or D2R transmission is successful, whether R2D transmission and / or D2R transmission is decoded successfully, whether R2D transmission and / or D2R transmission needs resources, and the like, which are not listed one by one here.

[0104] wherein the R2D transmission is also referred to as a transmission between a terminal (or referred to as a reader, or referred to as a terminal reader (UE reader)) and a first device (for example, an AIoT device); and the D2R transmission is also referred to as a transmission between the first device and the terminal.

[0105] Optionally, the assistance information includes, but is not limited to, at least one of the following:

[0106] a hybrid automatic repeat request acknowledgement (HARQ-ACK);

[0107] a scheduling request (SR);

[0108] a buffer status report (BSR);

[0109] channel state information (CSI);

[0110] a medium access control control element (MAC CE);

[0111] a radio resource control (RRC);

[0112] a request (request);

[0113] a response (response);

[0114] a report (report).

[0115] Step 202, the terminal sends the assistance information to a network side device on a first resource.

[0116] It should be noted that the first resource includes, but is not limited to, a time domain resource, a frequency domain resource, etc., which is not specifically limited in the embodiments of the present application, and the first resource is not specifically a certain resource.

[0117] Optionally, the first resource is related to the R2D transmission and / or the D2R transmission. For example, the first resource can be a time-frequency resource of the R2D transmission and / or a time-frequency resource of the D2R transmission, etc. It should be noted that, in the case that the R2D transmission includes at least one R2D transmission, the first resource is related to one or more R2D transmissions of the at least one R2D transmission; and / or, in the case that the D2R transmission includes at least one D2R transmission, the first resource is related to one or more D2R transmissions of the at least one D2R transmission. Wherein, the plurality in the embodiments of the present application is two or more than two.

[0118] It should be noted that, when the network side device allocates or configures the resource (for example, the first resource in the present application), it can be performed according to the granularity of the time window, such as one or more specific time windows; it can also be performed according to the resource or resource set, such as one or more resources or resource sets, further, it can be one or more time resources or time resource sets; it can also be performed according to the segment, such as one or more segments.

[0119] Optionally, in the embodiments of the present application, the first resource includes at least one of the following:

[0120] One or more time resources (for example, specific time resources), or, one or more time windows (for example, specific time windows), or, at least one uplink resource corresponding to one or more segment transmissions is the first resource;

[0121] All time resources or all specific time windows or all segment transmissions correspond to the same first resource.

[0122] For example, taking the segment transmission as an example, in one implementation, at least one uplink resource corresponding to one or more segment transmissions is the first resource. For example, in the case that the R2D transmission and / or the D2R transmission includes a plurality of segment transmissions, it can be that the uplink resources corresponding to some segment transmissions are determined as the first resource, for example, the uplink resources corresponding to two segment transmissions are determined as the first resource, or the uplink resources corresponding to three segment transmissions are determined as the first resource. Or, in another implementation, it can be that all segment transmissions correspond to the same first resource. Thus, the terminal can also determine the first resource based on different ways, so that the determination of the first resource is more flexible and diverse. The following will be described in combination with two specific embodiments.

[0123] For example, as shown in FIG. 3a, different specific time windows 1, 2, and 3 have corresponding uplink resources 1, 2, and 3 respectively. When at least part of the transmission or segmented transmission in the specific time window 2 meets the first target condition or the second target condition, the corresponding auxiliary information is sent on the uplink resource 2.

[0124] For example, as shown in FIG. 3b, three segmented transmissions form a group, the first group includes segments (transmissions) x1, x2, and x3, the second group includes segments y1, y2, and y3, and the third group includes segments z1, z2, and z3. The three groups of segmented transmissions have corresponding uplink resources x, y, and z respectively. When the segment y2 meets the second target condition, the corresponding auxiliary information is sent on the uplink resource y.

[0125] For example, as shown in FIG. 3b, three segmented transmissions form a group, the first group includes segments (transmissions) x1, x2, and x3, the second group includes segments y1, y2, and y3, and the third group includes segments z1, z2, and z3. The three groups of segmented transmissions have corresponding uplink resources x, y, and z respectively. When the segment y2 meets the second target condition, the corresponding auxiliary information is sent on the uplink resource y.

[0126] It should be noted that in some implementations, in the first target condition, all segmented transmissions or all time resources or time windows correspond to the same uplink resource, so that in the first target condition, the terminal sends the auxiliary information on the uplink resource; or there is no uplink resource, or the uplink resource is not used for actual transmission of auxiliary information; in the second target condition, at least part of the segmented transmissions or all specific time resources or specific time windows have respective corresponding uplink resources, and when all segmented transmissions meet the second target condition, the terminal sends the corresponding auxiliary information on the respective corresponding uplink resources of the segmented transmissions.

[0127] It should be noted that the specific time resources or specific time windows are also applicable to the above examples, which will not be described here. In this application, the terminal can also send the auxiliary information corresponding to the target condition on the corresponding uplink resource based on the target condition met by the specific time window or the specific time resource or the segmented transmission, so as to help the network side device quickly understand the state of AIOT transmission, and thus adjust to ensure orderly use of resources.

[0128] In the embodiments of the present application, after obtaining the assistance information, the terminal sends the assistance information to the network side device on the first resource. The assistance information is associated with a target condition, the target condition is related to R2D transmission and / or D2R transmission, and then the assistance information is also related to the R2D transmission and / or D2R transmission. Based on the received assistance information, the network side device can timely know the related condition of the R2D transmission and / or D2R transmission between the terminal and the first device, and perform related operations according to the assistance information, such as whether to need to schedule retransmission, or whether to need to continue CW transmission, or whether to need to schedule related resources for the first device, and the like, so as to better realize resource management. Correspondingly, the terminal can also perform corresponding operations according to the assistance information, such as whether to need to perform resource retransmission, whether to stop CW transmission, and the like, so as to help improve the communication quality between the terminal and the target device.

[0129] Optionally, in the embodiments of the present application, the target condition is related to at least one R2D transmission and / or at least one D2R transmission; in the case that the at least one R2D transmission includes at least two R2D transmissions and / or the at least one D2R transmission includes at least two D2R transmissions, wherein:

[0130] The at least two R2D transmissions correspond to the same assistance information; and / or,

[0131] The at least two D2R transmissions correspond to the same assistance information; and / or,

[0132] The at least two R2D transmissions have respective corresponding assistance information; and / or,

[0133] The at least two D2R transmissions have respective corresponding assistance information.

[0134] It should be noted that, taking the R2D transmission as an example, in the case that the target condition is related to at least one R2D transmission, in an implementation, at least two R2D transmissions in the at least one R2D transmission correspond to the same assistance information. For example, all R2D transmissions can correspond to the same assistance information; or every N (N≥2) R2D transmissions correspond to the same assistance information, for example, the first and second R2D transmissions correspond to assistance information 1, the third and fourth R2D transmissions correspond to assistance information 2, and the like; or a plurality of R2D transmissions can correspond to the same assistance information, where the plurality is not limited to a specific numerical value, for example, two R2D transmissions can correspond to assistance information 1, and the other three R2D transmissions correspond to assistance information 2, and the like.

[0135] Still taking the R2D transmission as an example, in another embodiment, in the case that the target situation is related to at least one R2D transmission, at least two R2D transmissions of the at least one R2D transmission have respective corresponding auxiliary information. For example, all the R2D transmissions can have respective corresponding different auxiliary information, or some of the R2D transmissions have respective corresponding auxiliary information, and the remaining R2D transmissions can have respective corresponding same auxiliary information or different auxiliary information or some of the R2D transmissions have respective corresponding same auxiliary information, and so on.

[0136] It should be noted that in the case that the target situation is related to at least one D2R transmission, the relationship between the at least one D2R transmission and the auxiliary information can refer to the above examples, which will not be repeated here.

[0137] In the embodiments of the present application, different R2D transmissions can have respective corresponding same auxiliary information or different auxiliary information, and different D2R transmissions can also have respective corresponding same auxiliary information or different auxiliary information, so that the network side device can perform relevant operations more targetedly according to the auxiliary information reported by the terminal, such as whether to schedule retransmission, whether to schedule resources, and so on, so that the network side device can more effectively realize resource association, thereby helping to improve the communication quality between the terminal and the network side device and between the terminal and the first device.

[0138] Optionally, the target situation includes a first target situation and / or a second target situation, wherein:

[0139] In the case that the first target situation is met, the auxiliary information is first auxiliary information; and / or,

[0140] In the case that the second target situation is met, the auxiliary information is second auxiliary information.

[0141] The first target situation can be different from the second target situation, and the first auxiliary information can be different from the second auxiliary information. That is, for different target situations, the auxiliary information reported by the terminal to the network side device is different, so that the network side device can perform relevant operations more targetedly based on different auxiliary information or for different target situations, so that the network side device can more effectively realize resource management, thereby helping to improve the communication quality between the terminal and the network side device and between the terminal and the first device.

[0142] Optionally, the first target situation includes at least one of the following:

[0143] (1) the terminal considers (or assumes) that the first device successfully receives or successfully decodes the R2D transmission; for example, the terminal considers (or assumes) that the first device successfully receives or successfully decodes all or expected or corresponding R2D transmission.

[0144] (2) the first device receives or decodes the R2D transmission; for example, the first device successfully receives or successfully decodes the R2D transmission.

[0145] (3) the first device sends the D2R transmission; it should be noted that in this case, the terminal can consider (or assume) that the first device sends the D2R transmission, or the first device sends the D2R transmission and is successfully received or successfully decoded by the terminal.

[0146] (4) the terminal listens to or receives the D2R transmission; for example, the terminal listens to or receives all or expected or corresponding D2R transmission.

[0147] (5) the terminal decodes the D2R transmission; for example, the terminal listens to or receives all or expected or corresponding D2R transmission, and decodes the D2R transmission, or successfully decodes the D2R transmission.

[0148] Optionally, for groupcast, the terminal decodes the D2R transmission includes that the terminal decodes all corresponding or all expected D2R transmission; and / or, for groupcast, the first device sends the D2R transmission includes that the terminal considers that all corresponding or all expected first device sends the D2R transmission.

[0149] Optionally, the all expected or all corresponding D2R transmission includes all expected or all corresponding D2R transmission of the first device.

[0150] In the embodiments of the present application, for groupcast, only in the case that the terminal decodes all corresponding or all expected D2R transmission of the first device, and / or the terminal considers that all corresponding or all expected first device sends the D2R transmission, the first target condition is met, thereby effectively defining the satisfaction condition of the first target condition in the groupcast scenario, so that the terminal can more accurately confirm that the auxiliary information is the first auxiliary information, and report to the network side device, so that the network side device takes related operations for the first auxiliary information, which helps the network side device to more effectively realize resource management.

[0151] Optionally, in the case that the first target condition includes that the first device sends a D2R transmission, or the terminal listens to or receives a D2R transmission, or the terminal decodes a D2R transmission, the D2R transmission indicates that the execution command is successful or the R2D command is successfully executed (such as Device successfully executed the command). Thus, the terminal can also confirm the success of the R2D transmission sent by itself based on the received or decoded D2R transmission.

[0152] It should be noted that the transmission in the present application includes sending and / or receiving, which will not be described in detail hereinafter.

[0153] Optionally, in the embodiments of the present application, the terminal obtaining the assistance information can be that the terminal determines the assistance information associated with the target condition, including at least one of the following:

[0154] (1) When the first target condition is met, the terminal determines that the assistance information is first assistance information.

[0155] For example, the first target condition can be that the D2R transmission is successful or decoding is successful, or the R2D transmission is successful or decoding is successful; or the D2R transmission (or decoding) is successful X1 times, or Y1 first devices successfully receive or successfully decode the R2D transmission (X1≥1, Y1≥1, X1 and Y1 can be the number of continuous successes or continuous or non-continuous successes in a period of time), etc. The first target condition can refer to the specific description above, which will not be described here.

[0156] When the first target condition is met, the assistance information is first assistance information.

[0157] Optionally, the first assistance information includes at least one of the following:

[0158] 1 or 0 of one or more bits, it should be noted that 1 can indicate that the R2D transmission and / or the D2R transmission is successful, and 0 can indicate that the R2D transmission and / or the D2R transmission fails;

[0159] Acknowledgement (ACK);

[0160] No resource is needed, or no additional resource is needed;

[0161] Resource is needed for new transmission;

[0162] Success;

[0163] Release of resources;

[0164] Transmission success or decoding success, or also referred to as transmission correct or decoding correct;

[0165] The terminal transmits the collected or received D2R information to the network side device; optionally, the terminal transmits the collected or received D2R information to the network side device through PUSCH completely (also referred to as transparently or directly), that is, the terminal does not process the D2R information and directly uploads the D2R information to the network side device. Optionally, the terminal transmits the correctly received or successfully decoded D2R information to the network side device. Further optionally, the correctly received or successfully decoded D2R information can include passing the CRC check.

[0166] It should be noted that the "receiving" (such as receiving D2R information, receiving D2R transmission, etc.) in the present application can be understood as receiving, successfully decoding after receiving, and / or passing the CRC check after receiving, which will not be described in detail hereinafter.

[0167] Optionally, the terminal transmits the collected or received D2R information to the network side device through PUSCH.

[0168] It should be noted that the transmission in the present application can be interpreted as sending and / or receiving. In the embodiments of the present application, when the target case is the first target case, the terminal obtains the first auxiliary information, and the terminal sends the first auxiliary information to the network side device. The network side device can know that the transmission between the terminal and the first device belongs to the first target case based on the received first auxiliary information, so that the network side device can perform corresponding operations, such as not configuring or scheduling resources, which helps the network side device to more effectively implement resource management and also helps to improve the communication quality between the terminal and the first device and between the network side device.

[0169] (2) When the second target case is met, the terminal determines that the auxiliary information is second auxiliary information.

[0170] For example, the second target case can be that the D2R transmission fails or decoding fails, or the R2D transmission fails or decoding fails; or the D2R transmission (or decoding) fails X2 times, or Y2 first devices fail to receive or decode the R2D transmission R2 times (X2≥1, Y2≥1, X2 and Y2 can be consecutive failures or the number of consecutive or non-consecutive failures in a period of time), etc. The second target case can be referred to the following specific description.

[0171] Optionally, the second target case includes at least one of the following:

[0172] (1) the terminal does not perform R2D transmission; it is noted that the terminal does not perform R2D transmission can also be referred to as the terminal cancels R2D transmission, or the terminal gives up R2D transmission, or the terminal drops R2D transmission, or the terminal stops R2D transmission, or the terminal terminates R2D transmission, or the terminal is unable to perform R2D transmission, etc.

[0173] Exemplarily, the network side device allocates or schedules resources, but at least one of them is cancelled or dropped or de-prioritized due to the priority comparison rule between Uu transmission and AIOT transmission, the first device is out of power, or the first device is about to go to sleep or off, or the reader is out of coverage, or the reader capability restriction, or the device capability restriction, then the terminal does not perform R2D transmission.

[0174] Alternatively, the network side device allocates or schedules resources, but the terminal buffer (e.g. UE reader buffer) is empty, then the terminal does not perform or is unable to perform R2D transmission.

[0175] Further alternatively, the network side device allocates or schedules resources, but the resources do not meet the requirements, such as the resources are insufficient to complete the AIOT process, or the time interval between the resources does not meet the requirement of the processing timeline, then the terminal does not perform R2D transmission.

[0176] (2) the terminal does not listen to or receive D2R transmission; it is noted that the terminal does not listen to or receive D2R transmission can also be referred to as the terminal cancels listening to or receiving D2R transmission, or the terminal gives up listening to or receiving D2R transmission, or the terminal stops listening to or receiving D2R transmission, or the terminal terminates listening to or receiving D2R transmission, etc.

[0177] For example, the terminal has sent a R2D transmission, there is a corresponding D2R transmission for the R2D transmission, but for some reasons, such as priority comparison rule between Uu transmission and AIOT transmission results in at least one of them being cancelled or discarded or de-prioritized (e.g. de-prioritization), the first device is out of power (e.g. device is out of power), or the first device is going to sleep or off (e.g. device go to sleep / off), or the reader is out of coverage (e.g. reader is out of coverage), or reader capability restriction (e.g. reader capability restriction), or device capability restriction (e.g. device capability restriction), etc., resulting in the terminal not listening to or not receiving the corresponding D2R transmission.

[0178] (3) the terminal does not listen to or does not receive the D2R transmission; in some scenarios, the first device sends the D2R transmission, but the terminal does not successfully listen to or successfully receive the D2R transmission; or in some scenarios, the first device does not send the D2R transmission, the terminal does not listen to or does not receive the D2R transmission.

[0179] Optionally, for groupcast, the terminal does not listen to or does not receive the D2R transmission includes that the terminal does not listen to or does not receive at least one expected or corresponding D2R transmission; further, the terminal does not listen to or does not receive at least one expected or corresponding D2R transmission of the first device.

[0182] (5) the terminal considers (or assumes) that the first device fails to decode the R2D transmission.

[0183] Optionally, for groupcast, the terminal considers (or assumes) that at least one expected or corresponding first device fails to decode the R2D transmission.

[0184] (6) the first device does not successfully receive the R2D transmission.

[0185] (7) the first device fails to decode the R2D transmission.

[0186] Optionally, for groupcast, the first device pair R2D transmission decoding failure comprises: at least one expected or corresponding first device pair R2D transmission decoding failure.

[0187] (8) the terminal considers (or assumes) that the first device does not send D2R transmission; in some embodiments, the not sending can also be expressed as canceling sending, giving up sending, stopping sending, discarding sending, terminating sending, etc., which will not be described in detail later. For example, the terminal considers (or assumes) that the first device does not send all or expected or corresponding D2R transmission.

[0188] Optionally, for groupcast, the terminal considers (or assumes) that the first device does not send D2R transmission comprises: the terminal considers that at least one expected or corresponding first device does not send D2R transmission.

[0189] For example, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission within or after the time interval corresponding to TR2Dmax, and the terminal considers (or assumes) that at least one expected or corresponding first device does not send D2R transmission. Further, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission of the first device within or after the time interval corresponding to TR2Dmax, and the terminal considers (or assumes) that at least one expected or corresponding first device does not send D2R transmission.

[0190] Alternatively, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission within or after the D2R transmission time resource, and the terminal considers (or assumes) that at least one expected or corresponding first device does not send D2R transmission. Further, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission of the first device within or after the D2R transmission time resource, and the terminal considers (or assumes) that at least one expected or corresponding first device does not send D2R transmission. Wherein, the D2R transmission time resource can be obtained by the terminal, for example, allocated or configured or scheduled by the network side device to the terminal.

[0191] (9) the first device does not send D2R transmission.

[0192] Optionally, for groupcast, the first device does not send D2R transmission comprises: at least one expected or corresponding first device does not send D2R transmission.

[0193] (10) the terminal considers (or assumes) that the first device D2R transmission fails.

[0194] Optionally, for groupcast, the terminal considers (or assumes) that the first device D2R transmission fails includes: the terminal considers that at least one expected or corresponding D2R transmission fails; further, the terminal considers that at least one expected or corresponding first device D2R transmission fails.

[0195] (11) the first device sends D2R transmission fails.

[0196] Optionally, for groupcast, the first device sending D2R transmission fails includes: at least one expected or corresponding first device sending D2R transmission fails.

[0197] (12) the terminal fails to decode D2R transmission, for example, the first device sends D2R transmission, but the terminal fails to decode D2R transmission. For another example, the terminal monitors (e.g. all or expected or corresponding) D2R transmission, and at least one D2R transmission decoding fails.

[0198] Optionally, for groupcast, the terminal fails to decode D2R transmission includes: the terminal fails to decode at least one expected or corresponding D2R transmission. For example, for groupcast, the terminal monitors all expected or all corresponding D2R transmission, and at least one D2R transmission decoding fails. Further, for groupcast, the terminal monitors all expected or all corresponding first device D2R transmission, and at least one D2R transmission decoding fails.

[0199] (13) the terminal monitors or receives D2R transmission indicating error or indicating failure or indicating unable to execute command; for example, the D2R transmission indicates that the first device encounters error (e.g. device encounters an error) or the first device fails to execute the command (e.g. device fails to execute the command).

[0200] Optionally, for groupcast, the terminal monitors or receives D2R transmission indicating error or indicating failure or indicating unable to execute command includes: the terminal monitors or receives at least one expected or corresponding D2R transmission indicating error or indicating failure or indicating unable to execute command. Further, for groupcast, the terminal monitors or receives at least one expected or corresponding first device D2R transmission indicating error or indicating failure or indicating unable to execute command.

[0201] (14) the terminal does not receive the expected or corresponding D2R transmission within or after a time interval corresponding to TR2Dmax, where TR2Dmax is the maximum time interval between a R2D transmission and its corresponding D2R transmission, e.g., the R2D transmission carries the resource information or scheduling information of the D2R transmission, and the interval between the R2D transmission and the D2R transmission is no more than TR2Dmax. For example, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission within or after a time interval corresponding to TR2Dmax, the terminal considers (or assumes) that at least one expected or corresponding first device does not successfully receive the R2D transmission or fails to decode the R2D transmission. Further, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission of at least one expected or corresponding first device within or after a time interval corresponding to TR2Dmax, the terminal considers (or assumes) that at least one expected or corresponding first device does not successfully receive the R2D transmission or fails to decode the R2D transmission. Optionally, the D2R transmission and / or the R2D transmission can include segmented transmission, e.g., at least one D2R segmented transmission and / or R2D segmented transmission.

[0202] (15) the terminal does not receive the expected or corresponding D2R transmission within or after the D2R transmission time resource. Where the D2R transmission time resource can be configured or scheduled by the network side device, and the first device can refer to at least one first device. Here, the acquired can be determined by the terminal itself, e.g., the D2R transmission time resource determined by the terminal, the D2R transmission time resource indicated or scheduled by the terminal, the D2R transmission time resource configured or scheduled or indicated by the network device.

[0203] Optionally, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission within or after the D2R transmission time resource, the terminal considers (or assumes) that at least one expected or corresponding first device does not successfully receive the R2D transmission or fails to decode the R2D transmission. Further, for groupcast, the terminal does not receive at least one expected or corresponding D2R transmission of at least one expected or corresponding first device within or after the D2R transmission time resource, the terminal considers (or assumes) that at least one expected or corresponding first device does not successfully receive the R2D transmission or fails to decode the R2D transmission.

[0204] It should be noted that the expected or corresponding D2R transmission in the present application includes the D2R transmission of the expected or corresponding first device. The expected or corresponding first device may be, for example, a target receiving device of the R2D transmission, a target sending device of the corresponding D2R transmission of the R2D transmission, and the device is expected to perform D2R transmission by, for example, a reader. The device can be considered as the expected or corresponding first device, such as a reader, which is expected to perform R2D reception. Details are not repeated hereinafter.

[0205] In the embodiments of the present application, the second target condition includes at least one of the above, and the terminal can further determine whether the current transmission state belongs to the second target condition according to the R2D transmission and / or the D2R transmission between the terminal and the first device, so as to determine the corresponding auxiliary information, i.e., the second auxiliary information.

[0213] In the embodiments of the present application, when the target condition is the second target condition, the auxiliary information obtained by the terminal is the second auxiliary information, and the terminal sends the second auxiliary information to the network side device on the first resource. The network side device can know that the transmission between the terminal and the first device belongs to the second target condition based on the received second auxiliary information, so that the network side device can perform corresponding operations, such as scheduling retransmission, stopping CW transmission, or scheduling additional resources, which helps the network side device to more effectively realize resource management and improve the communication quality between the terminal and the first device and between the network side device.

[0214] It should be noted that in the embodiments of the present application, the first resource includes at least one of the following:

[0215] One or more time resources (for example, specific time resources), or one or more time windows (for example, specific time windows), or one or more segment transmission corresponding at least one uplink resource is the first resource;

[0216] All time resources (e.g., a specific time resource) or all time windows (e.g., a specific time window) or all segmented transmissions correspond to the same first resource.

[0217] Optionally, the terminal transmits the assistance information on the first resource, including at least one of the following (e.g., taking a specific time window and a segmented transmission as an example):

[0218] Example 1 (case 1): In the case where a specific time window or X (X≥1) segmented transmissions correspond to at least one uplink resource, the at least one uplink resource is the first resource, and the terminal transmits the assistance information on the first resource.

[0219] For example, in the case where the first target condition or the second target condition is met, the uplink resource corresponding to the specific time window or the X segmented transmissions to which the transmission (e.g., D2R transmission) or the segmented transmission (e.g., D2R segmented transmission) that meets the first target condition or the second target condition belongs is the first resource, and the terminal transmits the assistance information on the first resource.

[0220] Case 2: In the case where all specific time windows or all segmented transmissions correspond to the same first resource, the terminal transmits the assistance information on the first resource.

[0221] For example, in the case where the first target condition or the second target condition is met, the first resource corresponding to the transmission (e.g., D2R transmission) or the segmented transmission (e.g., D2R segmented transmission) that meets the first target condition or the second target condition is transmitted on the first resource.

[0222] It should be noted that in the above case 1 and case 2, in the case where the segmented transmission is multiple, at least two of the multiple segmented transmissions correspond to the same assistance information; and / or, at least two of the multiple segmented transmissions have respective corresponding assistance information.

[0223] Optionally, the R2D transmission in the embodiments of the present application includes at least one segmented transmission, and / or the D2R transmission includes at least one segmented transmission. Alternatively, in some embodiments, multiple R2D transmissions can be understood as multiple segmented transmissions, and multiple D2R transmissions can be understood as multiple segmented transmissions.

[0224] It should be noted that the segmented transmission can include at least one of the following:

[0225] a) Transmission before or after a specific signal (e.g., the beginning or end of a specific signal or a certain rising edge or a certain falling edge or a certain chip boundary), as shown in FIG. 3c;

[0226] b) transmission between two (e.g. any two, specific two, or adjacent two) specific signals (start or end or some rising edge or some falling edge or some chip boundary) as shown in Fig. 3d;

[0227] c) two (e.g. any two, specific two, or adjacent two) specific signals (start or end or some rising edge or some falling edge or some chip boundary) and the transmission between them as shown in Fig. 3e;

[0228] d) one specific signal (e.g. start or end or some rising edge or some falling edge or some chip boundary of the specific signal) and the transmission before it (up to the start or end or some rising edge or some falling edge or some chip boundary of the previous specific signal) as shown in Fig. 3f;

[0229] e) one specific signal (e.g. start or end or some rising edge or some falling edge or some chip boundary of the specific signal) and the transmission after it (e.g. up to the start or end or some rising edge or some falling edge or some chip boundary of the next specific signal) as shown in Fig. 3g.

[0230] In an implementation, the above-mentioned some rising edge or some falling edge or some chip can be the first or last rising edge or falling edge or chip, or can be a specific rising edge or falling edge or chip.

[0231] In an implementation, the above-mentioned specific signal can be at least part of preamble and / or midamble and / or postamble, for example, the transmission between postamble and midamble can be understood as a segment, without any limitation. Any figure in the present application does not limit whether there is postamble or not, i.e. there can be or there can not be.

[0232] It should be noted that the midamble can also be replaced by other sequences or bits during R2D or D2R transmission, and further, these sequences or bits can contain sequences or bits satisfying predetermined rules or values.

[0233] It should be noted that the postamble can also be replaced by other signals or bits after R2D or D2R transmission, and these signals or bits can contain sequences or bits satisfying predetermined rules or values.

[0234] In an implementation, at least part of sequences or bits of at least two of the preamble and / or midamble and / or postamble can be the same.

[0235] In the embodiments of the present application, a segment can also be understood as one or more R2D transmissions, and / or one or more D2R transmissions. Different segments can belong to the same TB or different TBs (it should be noted that the explanation here can be any of the three segments currently discussed in AIOT), which is not limited in the present application. In addition, whether different segments are continuous or have a gap, the present application does not make any limitation.

[0236] Optionally, the at least two segment transmissions correspond to the same assistance information; and / or,

[0237] The at least two segment transmissions have respective corresponding assistance information.

[0238] For example, in an embodiment, the at least two segment transmissions correspond to the same assistance information. For example, all segment transmissions can correspond to the same assistance information; or every N (N≥2, N can be determined by a protocol, a network side device configuration, a UE reader indication, or a terminal capability) segment transmissions correspond to the same assistance information, for example, the first and second segment transmissions correspond to assistance information 1, the third and fourth segment transmissions correspond to assistance information 2, and so on; or a plurality of segment transmissions can correspond to the same assistance information, where the plurality is not limited to a specific number, for example, two segment transmissions can correspond to assistance information 1, and the other three segment transmissions can correspond to assistance information 2, and so on.

[0239] In another embodiment, the at least two segment transmissions have respective corresponding assistance information. For example, all segment transmissions can have respective corresponding different assistance information, or some of the segment transmissions have respective corresponding assistance information, and the remaining segment transmissions can correspond to the same assistance information or different assistance information or some of the segment transmissions correspond to the same assistance information, and so on. For example, an R2D transmission or a D2R transmission has N segments, and there are N corresponding assistance information.

[0240] In the embodiments of the present application, a plurality of segment transmissions can correspond to the same assistance information or different assistance information, so that the network side device accurately knows the current state of different segment transmissions based on the assistance information reported by the terminal, thereby facilitating the resource management of the network side device.

One possible case is that the terminal does not receive the D2R segment transmission indicating 'last segment' within or after the time interval corresponding to TR2Dmax (meaning that the D2R transmission is not completed within the specified time or resource), and the assistance information is second assistance information.

[0265] In some scenarios, in the case of including multiple segment transmissions, at least two of which correspond to the same assistance information, all segments in the multiple segment transmissions satisfy the second target condition, and the assistance information is second assistance information, for example, the second assistance information is used to indicate 0 or 1, or NACK, or the need for more additional resources, or the need for retransmission resources, or indicate failure, or indicate error, etc.

[0271] The terminal fails to decode the D2R segmented transmission, and the assistance message is second assistance information.

[0272] The terminal listens to the D2R segmented transmission indicating that the device encounters an error (e.g., device encounters an error) or the device fails to execute the command (e.g., device fails to execute the command), and the assistance message is second assistance information.

[0273] It should be noted that the second target condition can be specifically referred to the foregoing, and the second assistance information can be specifically referred to the foregoing, which will not be enumerated here.

[0274] In the embodiments of the present application, the terminal can determine the first assistance information or the second assistance information according to the target condition (i.e., the first target condition or the second target condition) met by the at least one R2D segmented transmission and / or the at least one D2R segmented transmission, and can perform relevant operations accordingly, thereby effectively ensuring the communication quality between the terminal and the first device and between the network side devices.

[0275] Optionally, in the case that the assistance information includes the second assistance information or in the case that the target condition includes the second target condition, the method further includes at least one of the following:

[0276] The terminal no longer monitors the subsequent D2R transmission;

[0277] The terminal retransmits the previous R2D transmission;

[0278] The terminal considers at least part of the scheduled or configured resources invalid; optionally, the at least part of the resources can be the resources after the terminal determines the assistance information or sends the assistance information, or the resources after the second target condition is confirmed to occur;

[0279] The terminal expects the network side device to stop the CW transmission;

[0280] The terminal expects the network side device to schedule retransmission;

[0281] The terminal expects the network side device to schedule additional resources;

[0282] The terminal considers or expects the CW transmission to stop;

[0283] The terminal considers or expects at least part of the resources corresponding to the CW to be invalid;

[0284] The terminal does not consider or does not expect the CW transmission to continue or continue;

[0285] the terminal does not consider or does not expect the CW transmission to occur at least in a certain time period;

[0286] the terminal stops the CW transmission.

[0287] In the embodiments of the present application, in the case that the assistance information includes the second assistance information or in the case that the target condition includes the second target condition, the terminal performs at least one of the above, so that the terminal can perform related operations for the second assistance information or the second target condition, and / or the network side device performs related operations, which helps the network side device to improve resource management efficiency, and also helps to improve the communication quality between the network side device, the terminal and the first device.

[0288] Optionally, the terminal considers or expects the CW transmission to stop at the start point or end point of the first resource, or at the start point or end point of the first resource after an offset, and / or the terminal considers or expects the resource corresponding to the CW to be invalid, and / or the terminal does not consider or does not expect the CW transmission to continue, and / or the terminal does not consider or does not expect the CW transmission to occur at least in a certain time period, and / or the terminal stops the CW transmission.

[0289] For example, as shown in FIG. 3h, the terminal decodes the segment (transmission) x3 and finds an error, sends the second assistance information in the corresponding first resource, and the network side device stops sending the CW at the time point after the offset of the first resource, or adjusts the power or waveform or resource of the CW, or sends the CW based on a certain power or a certain power limit, or sends the CW using a second resource, or sends the CW using a certain waveform, for example, adjusting the power of the CW can be to lower the transmission power or the maximum power limit of the CW; for example, adjusting the waveform of the CW can be to adjust to single tone CW, or to adjust to multi tone CW, further optionally, the adjusted CW waveform can be a waveform not supported by the first device; for example, adjusting the resource of the CW can be to send the CW on other resources, further optionally, the other resources are resources not configured or indicated to the first device, or resources not supported by the first device. If the CW is configured by other terminals or network side devices, the network side device can also instruct other terminals or network side devices to stop sending the CW or adjust the power or waveform or resource of the CW.

[0290] The offset can be indicated by the network side device, or agreed by the protocol, or related to the capability of the first device, or related to the capability of the terminal, or determined by the terminal. The offset of 0 can also be understood as no offset, i.e., the CW is not sent at the time point of the first resource, or the transmission power or waveform or resource of the CW is adjusted.

[0291] Optionally, in a case that the offset is determined by the terminal, the method further comprises: the terminal reporting the offset to a network side device. In turn, the network side device can perform relevant operations based on the offset, for example, the network side device stops CW transmission at the start or end of the first resource, or at the start or end of the first resource after an offset, or schedules retransmission, etc., effectively improving resource management efficiency and helping to improve communication quality.

[0292] The advantage of the scheme is that the network side device or the reader (e.g., the terminal) can make corresponding adjustments based on the situation. For example, a D2R transmission can contain several hundred bits, so it needs to occupy a very long time to complete, for example, several hundred milliseconds or several seconds, but the D2R transmission is out of error when several bits are transmitted, or the reader finds that the D2R decoding is out of error, or finds that the D2R indication is out of error, and it is meaningless to continue to transmit. If the reader controls the CW, the reader can stop the CW to terminate the D2R transmission, and / or the reader can consider retransmitting R2D to trigger D2R retransmission. The reader can also report this situation to the network side device. If the network side device controls the CW, the network side device can stop the CW to terminate the D2R transmission, or schedule retransmission, etc.

For example, adjusting the power of the CW can be reducing the transmission power or the maximum power limit of the CW; for example, adjusting the waveform of the CW can be adjusting to a single-tone CW or a multi-tone CW, and further optionally, the adjusted CW waveform can be a waveform not supported by the first device; for example, adjusting the resource of the CW can be adjusting to send the CW on other resources, and further optionally, the other resources are resources not configured or indicated to the first device or resources not supported by the first device.
