[0050] Before the embodiments of the present application are described, the related art will be briefly introduced as follows:

[0051] In addition to communication capability, future mobile communication systems such as B5G systems or 6G systems will also have sensing capability. One or more devices with sensing capability can perceive the position, distance, speed, etc. of a target object through the transmission and reception of wireless signals, or detect, track, identify, image, etc. target objects, events or environments, etc. In the future, with the deployment of small base stations with high-frequency large-bandwidth capability such as millimeter waves and terahertz in 6G networks, the resolution of sensing will be significantly improved compared to centimeter waves, so that 6G networks can provide more refined sensing services. Typical sensing functions and application scenarios are shown in Table 1.

[0052] Table 1

[0053] Communication and sensing integration means that communication and sensing functions are integrated in the same system through spectrum sharing and hardware sharing. The system can perceive the position, distance, speed, etc. while transmitting information, and detect, track, identify target devices or events. The communication system and the sensing system complement each other to improve the overall performance and bring better service experience.

[0054] The integration of communication and radar belongs to a typical application of communication and sensing integration (communication and sensing fusion). In the past, radar systems and communication systems were strictly separated due to different research objects and focuses, and the two systems were independently researched in most scenarios. In fact, radar and communication systems are typical ways of information sending, obtaining, processing and exchanging, and there are many similarities in working principles, system architectures and frequency bands. The design of the integration of communication and radar has great feasibility, mainly in the following aspects: first, both communication systems and sensing systems are based on electromagnetic wave theory and use electromagnetic wave transmission and reception to obtain and transmit information; second, both communication systems and sensing systems have structures such as antennas, sending ends, receiving ends and signal processors, and there is a great overlap in hardware resources; with the development of technology, there are more and more overlaps in the working frequency bands; in addition, there are similarities in key technologies such as signal modulation and reception detection and waveform design. The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, spectrum efficiency improvement, mutual interference reduction and the like, thereby improving the overall performance of the system.

[0055] As shown in FIG. 2, according to the difference between the sending node and the receiving node of the sensing signal, the following six sensing links are divided.

[0056] 1) Base station self-transmission and self-reception sensing. In this way, the base station transmits the sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

[0057] 2) Inter-base-station air interface sensing. At this time, base station 2 receives the sensing signal transmitted by base station 1 and obtains the sensing result.

[0058] 3) Uplink air interface sensing. At this time, the base station receives the sensing signal transmitted by the UE and obtains the sensing result.

[0059] 4) Downlink air interface sensing. At this time, the UE receives the sensing signal transmitted by the base station and obtains the sensing result.

[0060] 5) Terminal self-transmission and self-reception sensing. At this time, the UE transmits the sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

[0061] 6) Inter-terminal sidelink sensing. For example, UE 2 receives the sensing signal transmitted by UE 1 and obtains the sensing result.

[0062] It is worth noting that each sensing link in FIG. 2 takes one sending node and one receiving node as an example, in an actual system, different sensing links can be selected according to different sensing requirements, the sending node and the receiving node of each sensing link can be one or more, and the actual sensing system can include multiple different sensing links. The sensing objects in FIG. 2 take people and vehicles as examples, and the sensing objects of the actual system will be more abundant.

[0063] For a communication node (for example, a network side device or a terminal) that cannot perform sensing, when there is an operation to be performed (for example, link interruption or multiple operation attempts fail), due to the lack of effective sensing information of the surrounding environment, the communication node can only make decisions based on the historical information stored by itself, which leads to the communication node making inappropriate decisions.

[0064] In view of this, the embodiments of the present application provide an information transmission method, an information transmission device and a communication device to solve the problem of inappropriate decisions of a communication node that cannot perform sensing due to the lack of effective sensing information of the surrounding environment in the related art.

[0065] The information transmission method provided by the embodiments of the present application will be described in detail below in combination with the drawings, some embodiments and application scenarios.

[0066] FIG. 3 shows a flowchart of an information transmission method provided by an embodiment of the present application. As shown in FIG. 3, the information transmission method includes the following steps:

[0067] Step 301: A first node reports or indicates first information to a second node, the first information being used to indicate at least one of the following:

[0068] sensing type, sensing direction, sensing report granularity, whether there is an obstacle, sensing time delay, Doppler, channel path coefficient, azimuth and elevation, reference signal measurement result, position, speed and attitude of a node performing sensing signal transmission and reception, whether a sensing target exists, parameters of the sensing target, channel state information (CSI), beam measurement result, sensing accuracy, identifier (ID) of the sensing target, cell ID, user equipment (UE) ID.

[0069] In the embodiments of the present application, the first node can be understood as or replaced by a first device, and the second node can be understood as or replaced by a second device. The first information can be understood as sensing related information, and the first information can be specifically understood as sensing information or sensing result.

[0070] For example, the first node is a terminal, and the second node is a network side device, and then the first node reports the first information to the second node.

[0071] For example, the first node is a network-side device, and the second node is a terminal. In this case, the first node indicates the first information to the second node.

[0072] The sensing type may, for example, include at least one of the following types:

[0073] Monostatic sensing: a node / device senses a signal by itself;

[0074] Bistatic sensing mode A: a node / device transmits a sensing signal;

[0075] Bistatic sensing mode B: a node / device receives a sensing signal for sensing;

[0079] The sensing direction may be understood as or replaced by a sensing manner. The sensing direction may, for example, include sensing based on an indicated TCI direction or omnidirectional sensing.

[0080] Whether there is an obstacle may be indicated by 1 bit or N bits, for example, 0 or 1 is used to represent whether there is an obstacle, or N bits are used to represent whether various obstacles exist.

[0081] The unit of the sensing delay may, for example, include a slot, a symbol, a millisecond (ms), a second (s), a frame, a subframe, a tc, or a ts, etc. The sensing delay is related to a subcarrier structure or the type of a node or device.

[0082] The Doppler may, for example, be in hertz (hz) or subcarriers.

[0083] The channel path coefficient may be a relative value, such as the relative proportion of a LOS and one or more non-LOS.

[0084] The azimuth angle and the elevation angle may be in degrees, radians, etc.

[0085] The reference signal measurement result may include, for example, a reference signal received power (RSRP), a reference signal received quality (RSRQ), a signal-to-noise and interference ratio (SINR).

[0086] The parameters of the perception target may include, for example, a distance, a speed, an orientation, an acceleration, a position, a trajectory, an action, an expression, a breathing / heart rate, an imaging result, a weather, an air quality, a material, and a composition.

[0087] In an embodiment of the present application, the first node reports or indicates the first information to the second node, and the first information is used to indicate at least one of the following: a perception type; a perception direction; a perception reporting granularity; whether there is an obstacle; a perception time delay; a Doppler; a channel path coefficient; an azimuth angle and an elevation angle; a reference signal measurement result; a position, a speed, and a pose of a node performing the perception signal transmission and reception; whether the perception target exists; a parameter of the perception target; a CSI; a beam measurement result; a perception accuracy; an ID of the perception target; a cell ID; and a UE ID. In this way, the first node reports or indicates the first information to the second node, so that the second node can obtain effective perception information of the surrounding environment even if the second node cannot perform perception, thereby facilitating the second node to make a decision.

[0088] In some embodiments, the first information is carried in at least one of the following:

[0089] A message 3 (Msg3); a message A (MsgA); uplink control information (UCI); a medium access control control element (MAC CE); a control channel; a data channel; a message between the first node and the second node; and a message transmitted through an Xn interface.

[0090] For the first information carried in the Msg3, for example, the first information may be carried in Msg3 physical uplink shared channel (PUSCH) information or Msg3 PUSCH demodulation reference signal (DMRS) resources.

[0091] For the first information being carried in MsgA, for example, the first information can be carried by MsgA PUSCH, or the first information can be carried by DMRS resource of MsgA PUSCH, or the first information can be carried by MsgA Physical Random Access Channel (PRACH) part.

[0092] The control channel can be a Physical Uplink Control Channel (PUCCH), for example, and the data channel can be a PUSCH, for example.

[0093] The message between the first node and the second node can be control plane information or user plane information between the first node and the second node, for example. The first node (or the second node) can be a base station, a Reconfigurable Intelligent Surface (RIS) device, a repeater, or a relay, for example.

[0094] In some embodiments, the form of the first information is configured by a network side device or predefined by a protocol;

[0095] The form of the first information includes at least one of the following:

[0096] The content or dimension of the perception target of the first information;

[0097] The physical unit corresponding to the content or dimension of the perception target.

[0098] The form of the first information can be understood or replaced as the format of the first information.

[0099] For example, whether the perception target exists is a dimension, the height of the perception target is a dimension, and the width of the perception target is another dimension. Taking the height of the perception target as an example, the corresponding physical unit can be centimeters, meters, kilometers, etc.

[0100] In some embodiments, the first node or the second node includes at least one of the following:

[0101] Terminal; base station; Reconfigurable Intelligence Surface or Intelligent Reflection Surface; relay; satellite; high-altitude equipment; tag; Transmit / Receive Point (TRP); smart watch; helmet; Customer Premises Equipment (CPE); object with tag; reduced capability; Internet of Things (IoT) device; XR device; robot.

[0102] IoT devices may, for example, include Ambient Internet of Things (AIoT), Narrowband Internet of Things (NB-IoT), 6G-IoT, and the like low-power and / or wide-coverage devices.

[0103] In some embodiments, the reporting or indicating manner of the first information includes at least one of the following:

[0104] The first information is reported or indicated independently.

[0105] The first information is reported or indicated jointly with a CSI report.

[0106] Reporting or indicating the first information independently can be understood as reporting the first information independently of other CSI or Hybrid automatic repeat request acknowledgement (HARQ-ACK) / negative acknowledgement (NACK) information.

[0107] Reporting or indicating the first information jointly with a CSI report can be understood as the first information being one or more types of CSI, or as the first information being reported jointly with other CSI reports (for example, the first information being reported in a CSI report together with other CSI), or as the CSI report carrying the first information.

[0108] It should be noted that the CSI report carrying the first information can be referred to as a CSI carrying perception information, or a perception CSI, or a perception CSI report, or a CSI report carrying perception information, which can be understood as one or more or at least one or more perception information or perception related information configuration information, or can be directly expressed as perception information or perception information reporting, and does not necessarily be referred to as CSI or CSI report.

[0109] When the first information and the CSI report are jointly reported, how to determine the priority of the CSI report is a problem to be solved. The following describes the related embodiments of the CSI reporting priority.

[0110] In some embodiments, in the case that the target CSI report carries the first information, the priority of the target CSI report is determined based on at least one of the following:

[0111] A first priority rule, the first priority rule is used to determine the priority of a first CSI report and a second CSI report, the first CSI report is a CSI report carrying perception information, and the second CSI report is a CSI report not carrying perception information;

[0112] A second priority rule, the second priority rule is a priority rule configured by a network side device, or the second priority rule is a default priority rule.

[0113] In this embodiment, based on the above priority rule, the priority of the CSI report carrying the perception information can be improved or reduced. Among them, the way of configuring the priority rule by the network side device can make the network side device have strong flexibility, for example, when the network side device needs perception information, the priority of the CSI report can be improved, and when the network side device does not need perception information, the priority of the CSI report can be reduced.

[0114] In some embodiments, the first priority rule is expressed as the following formula:

[0115] Pri iCSI (y, k, c, s, z) = 2 · N cells · M s · Z · y + N cells · M s · Z · k + · M s · Z · c + s · Z + z

[0116] Among them, the parameter z is related to whether the CSI report carries perception information, or the parameter z is related to the priority of the perception information carried by the CSI report, or the parameter z is related to the content of the perception information carried by the CSI report.

[0117] Z is equal to the number of values that parameter z can take.

[0118] The above formula can be understood as a CSI report priority formula. Z is equal to the number of values that parameter z can take. For example, if parameter z can take values 0 and 1, the number of values that parameter z can take is 2, and then the value of Z is 2.

[0119] In addition, the value of parameter y can include the following cases:

[0120] y = 0, the PUSCH will perform an aperiodic CSI report;

[0121] y = 1, a semi-persistent CSI report on the PUSCH;

[0122] y = 2, the semi-persistent CSI report will be performed on the PUCCH;

[0123] y = 3, the CSI report is periodically performed on the PUCCI.

[0124] The value of parameter k can include the following cases:

[0125] k = 0, the CSI report carries Layer 1 reference signal received power (L1-RSRP) or L1-SINR;

[0126] k = 1, the CSI report does not carry L1-RSRP or L1-SINR.

[0127] Parameter c represents the index of the serving cell.

[0128] N cells represents the value of the upper-layer parameter maxNrofServingCells.

[0129] Parameter s represents parameter reportConfigID.

[0130] M s represents the value of the upper-layer parameter maxNrofCSI-ReportConfigurations.

[0131] Optionally, the value of parameter z is indicated or configured by the second node.

[0132] For example, if the CSI report carries awareness information, then z = 0; otherwise, z = 1.

[0133] For another example, different types of awareness information have different z values, as shown in Table 2:

[0134] Table 2

[0135] wherein different perception information can be distinguished according to at least one of the following:

[0136] (1) According to the type of perception, the z value corresponding to different perception information is distinguished, such as:

[0137] z = 0, Monostatic perception;

[0138] z = 1, bistatic perception mode A;

[0139] z = 2, bistatic perception mode B.

[0140] (2) According to the way of perception, the z value corresponding to different perception information is distinguished, such as:

[0141] z = 0, omnidirectional perception;

[0142] z = 1, perception based on the indicated TCI direction.

[0143] (3) According to the content of the perception information, the z value corresponding to different perception information is distinguished, such as:

[0144] z = 0, the perception information contains positioning information related content;

[0145] z = 1, the perception information contains temperature related content;

[0146] z = 2, the perception information contains speed related content.

[0147] The value of the parameter z can also be indicated by the node (such as the network), and the node configures it through one or more messages (such as Radio Resource Control (RRC), Downlink Control Information (DCI), MAC CE, Random Access Response (RAR), fallback RAR, Paging, Wake-up signal (WUS), WUS feedback signaling, Synchronization Signal Block (SSB), other signaling carrying perception configuration information, etc. signaling to configure.

[0148] It should be noted that the SSB involved in the embodiments of the present application can also be referred to as a module containing at least one of a synchronization signal, a broadcast signal, a physical broadcast channel (PBCH), other system message downlink broadcast channels or control channels thereof, other dedicated signals or channels.

[0149] Optionally, the second node indicates a value of the parameter z when indicating the reporting of the first information.

[0150] Optionally, the second node configures or resets or updates the value of the parameter z through at least one of a MAC CE, a DCI, a RAR, a message 2 (Msg 2), a message B (Msg B), a paging message (such as a paging short message), system information, and a target message.

[0151] The target message is a message carrying awareness configuration information. For the priority rules configured by the network side device or the default priority rules, for example, the priority of the CSI report carrying awareness information by default is higher than the priority of the CSI report without carrying awareness information, or the priority of the CSI report carrying awareness information by default is lower than the priority of the CSI report without carrying awareness information. In the same category of CSI report, the priority of the CSI report is determined according to the priority formula in the related art. For example, for the CSI report carrying different types of awareness information, different reporting priorities can be defined. For example, one or more priority rules are defined, and the network side device indicates the specific priority rule.

[0152] In some embodiments, in the case that the target CSI report carries the first information, the number of CPUs occupied by the target CSI report is determined in the following manner:

[0153] In the case that the reference signal used for awareness and the reference signal used for CSI reporting have no intersection, the number of CPUs occupied by the target CSI report is equal to the number of resources of the first resource set plus the number of resources of the second resource set.

[0154] In the case that the reference signal used for awareness and the reference signal used for CSI reporting are the same reference signal, the number of CPUs occupied by the target CSI report is equal to the number of resources of the first resource set.

[0155] The first resource set is a resource set of a reference signal used for channel measurement, and the second resource set is a resource set of a reference signal used for awareness measurement.

[0156] The number of CPUs, also referred to as the quantity of CPUs, occupied by a target CSI report can be denoted as O CPU The number of CPUs occupied by a target CSI report O CPU is related to the number of resources in the resource set used as CSI-RS for channel measurement.

[0157] The following describes the determination manner of the start position and the end position of the CPUs occupied by a CSI report.

[0158] In some embodiments, in the case that a target CSI report carries the first information, the determination manner of the start position and the end position of the CPUs occupied by the target CSI report comprises at least one of the following:

[0161] In some embodiments, the start position and the end position of the CPUs occupied by the target CSI report are predefined by a protocol, which comprises at least one of the following:

[0162] For a periodic CSI report and a non-initial semi-persistent (SP) CSI report reported on a physical uplink shared channel (PUSCH) triggered by a physical downlink control channel (PDCCH), the CPU of the target CSI report occupies from the first symbol of the earliest measurement resource used for channel measurement or interference measurement or sensing measurement to the end of the last symbol of the PUSCH or the PUCCH carrying the CSI report;

[0163] For a dynamic CSI report and an initial SP CSI report reported on a PUSCH triggered by a PDCCH, the CPU of the target CSI report occupies from the first symbol of the PDCCH trigger to the end of the last symbol of the PUSCH or the PUCCH carrying the CSI report;

[0164] For a dynamic CSI report and an initial SP CSI report reported on a PUSCH triggered by a PDCCH, the CPU of the target CSI report occupies from the first symbol of the control resource set (CORESET) where the PDCCH is located to the end of the last symbol of the PUSCH or the PUCCH carrying the CSI report;

[0165] For dynamic CSI reporting, and PDCCH triggered initial SP CSI reporting on PUSCH, the starting position of the CPU occupied by the target CSI report is the first symbol of the earliest measurement resource for channel measurement or interference measurement or sensing measurement, and the ending position of the CPU occupied by the target CSI report is the end of the last symbol of the PUSCH or PUCCH carrying the CSI report.

[0166] For dynamic CSI reporting, and PDCCH triggered initial SP CSI reporting on PUSCH, the starting position of the CPU occupied by the target CSI report is the first symbol of the earliest measurement resource for channel measurement or interference measurement or sensing measurement, and the ending position of the CPU occupied by the target CSI report is the end of the last symbol of the PUSCH or PUCCH carrying the CSI report.

[0167] The earliest measurement resource (also referred to as measurement signal resource) for channel measurement or interference measurement or sensing measurement described above may be, for example, a CSI reference signal (CSI Reference Signal, CSI-RS), a CSI interference measurement (CSI Intereference Measurement, CSI-IM), an SSB, or a sensing measurement signal resource.

[0172] At least one of the start position, the time length, and the end position of the specific time window (or the specific timer) can be indicated by a PDCCH that schedules a channel on which CSI is reported, by a PDCCH or a PDSCH (Physical downlink shared channel) that triggers reporting, by other RRC signaling, MAC-CE, RAR, Msg2, MsgB, a paging message, and the like.

[0326] The following provides a plurality of specific embodiments to exemplarily illustrate the embodiments of the present application.

[0327] Embodiment 1: UE reports sensing results in a random access procedure

[0328] The main idea of the present embodiment is that the UE reports the sensing results to the base station in the random access procedure, thereby solving the problem that the base station cannot obtain effective sensing information before performing operations, and enabling the base station to obtain effective information in advance, which is conducive to the base station making appropriate decisions.

[0329] As shown in FIG. 5, the corresponding signaling flow is as follows:

[0330] Step 1: The UE has a demand to initiate connection establishment, and the UE sends Msg1;

[0331] Step 2: The network side device instructs the UE to sense the surrounding devices / environment in Msg2;

[0332] Step 3: The UE senses the surrounding devices / environment;

[0333] Step 4: The UE carries the sensing results (i.e., the first information) in Msg3 and reports to the base station;

[0334] Step 5: The base station receives the sensing results and sends Msg4;

[0335] Step 6: Based on the sensing results reported by the UE, the base station can have a better understanding of the environment around the UE, and can more quickly and accurately determine the appropriate beam direction, code rate, or modulation and coding mode for service transmission, etc., which is conducive to ensuring the reliability of subsequent service transmission.

[0336] Embodiment 2: Sensing results and CSI are jointly reported

[0337] In some embodiments, the sensing results (i.e., the first information) can be jointly reported with the CSI, for example, the sensing information is carried in the CSI part 1 (part 1), as shown in Table 3, including carrying an indication of whether there is blockage, carrying specific information of the blocking object, etc.

[0338] Table 3

[0339] In some embodiments, the perception result can be reported in CSI part 2, such as carrying the perception result in CSI part 2, including the moving speed, moving direction, straight-line distance, temperature, etc. of the perceived surrounding objects.

[0340] Embodiment 3: Priority determination of CSI report carrying perception result (i.e. first information)

[0341] In some embodiments, the UE determines the priority of the CSI report according to the following priority formula:

[0342] Pri iCSI (y, k, c, s, z) = 2 · N cells · M s · Z · y + N cells · M s · Z · k + · M s · Z · c + s · Z + z

[0343] Wherein, y = 0, the PUSCH will perform an aperiodic CSI report;

[0344] y = 1, the semi-persistent CSI report performed on the PUSCH;

[0345] y = 2, the semi-persistent CSI report will be performed on the PUCCH;

[0346] y = 3, the CSI report is periodically performed on the PUCCI;

[0347] k = 0, the CSI report carrying Layer 1 reference signal received power (L1-RSRP) or L1-SINR;

[0348] k = 1, the CSI report does not carry L1-RSRP or L1-SINR;

[0349] c represents the index of the serving cell;

[0350] N cells represents the value of the upper layer parameter maxNrofServingCells;

[0351] s represents the parameter reportConfigID;

[0352] M s represents the value of the upper layer parameter maxNrofCSI-ReportConfigurations;

[0353] z = 0, the CSI report carries sensing results;

[0354] z = 1, the CSI report does not carry sensing results;

[0355] That is, the value of z is determined by the protocol in advance according to whether the CSI report carries sensing results.

[0356] The UE determines the priority of the CSI report according to the above formula.

[0357] Embodiment 4: Sensing results

[0358] As shown in Table 4, the contents of the sensing result report can include:

[0373] Embodiment 6: Sensing capability reporting through different PRACH, MsgA, MsgA-PUSCH, Msg3 resources or explicit indication

[0374] When the UE has multiple sensing capabilities, the combination of various capabilities can be reported through different PRACH, MsgA, MsgA-PUSCH, Msg3 resources or explicit information.
