Information transmission method and node device

[0001] Cross-reference to related applications

[0002] The present application claims priority from Chinese Patent Application No. 202010415262.X filed on May 15, 2020, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of communication, in particular to an information transmission method and a node device. BACKGROUND

[0004] In related technologies, the working bandwidth of a smart surface is relatively wide, for example, from several GHz to tens of GHz, and the bandwidth of each generation of system of an operator (for example, the fourth generation (4 th Generation,4G), the fifth generation (5 th Generation,5G)) is relatively small, from tens of MHz to hundreds of MHz. After the signals emitted by base stations of different operators are incident on the smart surface, the direction of the reflected signals or the direction of the refracted signals can be controlled by the control circuit of the smart surface to achieve coverage enhancement or blind filling. Since the working bandwidth of the smart surface is significantly larger than the bandwidth of a single operator's system, or in other words, since the working bandwidth of the smart surface covers the bandwidths of multiple operators, the following conflict events may occur: for example, one base station of operator A hopes that the smart surface covers the signal of the base station in direction 1, while one base station of operator B hopes that the smart surface covers the signal of the base station in direction 2. However, the smart surface can only control the main reflected wave in one direction at a time.

[0078] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0079] The terms "first", "second", and the like in the description and in the claims of this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of the terms so construed can interchange their position and / or order, where appropriate, depending upon the context in which they are used. Also, the use of the term "including" and "comprising" as well as their derivatives, is meant to encompass the inclusion not an exclusive or exhaustive inclusion of the specified element or the elements listed and any additions of one or more other elements or quantifiers that are not specifically preceded by the coordinating term, but that are found together under the same heading. The term "and / or" between the conjoined objects connotes at least one of the conjoined objects.

[0080] The following description provides examples, and is not limiting of the scope, applicability, or configuration set forth in the claims. Changes can be made in the function and arrangement of elements discussed without departing from the scope and spirit of aspects of the disclosure. Various examples can omit, substitute, or add various procedures or components as appropriate. For instance, the methods described can be performed in an order different from that described, and other steps can be added, omitted, or combined. Also, features described with respect to certain examples can be combined in other examples.

[0081] In order for those skilled in the art to better understand the embodiments of the present application, the following description is made.

[0082] Intelligent surface is an emerging technology, and there are many related terms that represent similar technologies or entities, including:

[0083] Large Intelligent Surface (LIS), Smart Reflect Array (SRA), Reconfigurable Reflect Array (RRA), Intelligent Reflecting Surface (IRS).

[0084] Among them, IRS is composed of a large number of low-cost passive reflecting elements, and IRS is an electromagnetic metamaterial or metasurface. Each reflecting element can independently induce changes in the amplitude, phase and / or polarization of the incident signal, that is, by controlling the reflection to reconfigure the wireless propagation environment. Since IRS does not use a transmitting radio frequency (RF) chain, it has the characteristics of low cost and low energy consumption.

[0085] Compared with existing active relay communication, IRS does not use active transmitting modules, but only reflects the received signal. Active relay communication usually operates in half-duplex mode, which has lower spectral efficiency than IRS operating in full-duplex mode; compared with existing backscatter communication (such as Radio Frequency Identification (RFID)), IRS, as a passive reflecting device, does not send its own information, but only serves to facilitate existing communication links; compared with existing large-scale Multi Input Multi Output (MIMO) technology, the operating principles of the two are very different. IRS is a passive array, while large-scale MIMO is an active array; IRS is generally used as a reflecting array, while large-scale MIMO is generally used as a transmitting array. Compared with large-scale MIMO technology, IRS has the advantages of low hardware cost, low transmission loss, and better suitability for microwave and millimeter wave (mmWave) frequency bands.

[0086] There are several types of IRS reflecting units:

[0087] A. Tunable resonator: A variable capacitor is integrated into the resonator, which changes the frequency of the frequency-agile patch resonator to produce a phase shift.

[0088] B. Guided-wave control method: In this case, the arriving spatial wave is coupled by the antenna to the guided wave, and then the guided wave is phase-shifted and re-emitted, forming an antenna phase shifter.

[0089] C. Rotation technology of circularly polarized wave: designed by using the reflection law of electromagnetic wave.

[0090] From the perspective of whether it can be dynamically controlled, the reflecting array / intelligent surface is divided into two categories:

[0091] 1) Static reflecting array / intelligent surface: The structure and function of the reflecting array can be fixed. For an incident wave at an angle, the metasurface unit causes the amplitude, phase, polarization mode, etc. of the incident wave to change fixedly, and the corresponding reflected wave is obtained.

[0092] 2) Dynamic reflective array / smart surface: The structure and function of the reflective array can be controlled. For an incident wave of an angle, the amplitude, phase, polarization mode, etc. of the incident wave can be changed by programmable control to obtain the corresponding reflected wave. To achieve programmable control of the reflective metasurface, a switching element (such as a diode, a radio frequency micro-electromechanical system (RF-MEMS) switch, etc.) is introduced in the reflective unit. The PIN diode is a common choice for controlling the reconfigurable metasurface. The PIN diode has a wide range of radio frequency impedance and low distortion, and is widely used in the field of microwave radio frequency. The switching element in the reflective unit has multiple different states, and the switching between different states can be realized by controlling the on-off of the switching element. The switching element has a large change in the structure and performance of the corresponding reflective unit in the on-off state. That is, the reflective unit in different states has different regulation modes for the amplitude, phase, polarization, etc. of the incident wave.

[0093] As shown in FIG. 1, an embodiment of the present application provides an information transmission method, which applies a first node device, which can be a base station in particular, and the method comprises:

[0094] Step 101: negotiating target information with a second node device.

[0095] The second node device can be a node device belonging to the same operator as the first node device, or the second node device can also be a node device belonging to a different operator from the first node device, and the second node device is a base station in particular.

[0096] Optionally, the second node device has the same station address and the same antenna direction as the first node device.

[0097] Alternatively, the second node device has a different station address from the first node device.

[0098] Alternatively, the second node device has a different antenna direction from the first node device.

[0099] The first node device and the second node device negotiate the target information through a 5G base station (gNB) interface, a long term evolution (LTE) base station (eNB) interface, a gNB and eNB interface, or other interfaces.

[0100] Step 102: determining the working information of a third node device according to the target information.

[0101] The third node device is a node device associated with the first node device and the second node device, and specifically, is an intelligent surface.

[0102] The target information includes at least one of the first information, the second information, feedback information of the first information, and feedback information of the second information.

[0103] The first information refers to working information of the third node device expected by the first node device.

[0104] The second information refers to working information of the third node device expected by the second node device.

[0105] The feedback information includes acknowledgement (ACK) information or negative acknowledgement (NACK) information.

[0106] The determined working information of the third node device includes identification information of the third node device.

[0107] The determined working information of the third node device further includes at least one of the following:

[0108] Switching information of a switching element of a reflection or refraction unit in the third node device;

[0109] A working mode of the third node device;

[0110] Phase-related information;

[0111] Amplitude-related information;

[0112] Polarization mode-related information;

[0113] Frequency-related information.

[0114] In an embodiment of the present application, the identification information of the third node device can be an ID or an index of the third node device, and the third node device can be an LIS, an SRA, an RRA, or an IRS. The third node device associated with the target information is determined through the identification information.

[0115] The switch information of the switch element of the reflecting or refracting unit in the third node device can be a pattern of the switch element. The switch element enables the reflecting unit or the refracting unit to have multiple different states, and the switch element is controlled to be on or off to switch between the different states, wherein the reflecting wave or the refracting wave corresponding to the different states is different in direction, phase, amplitude and / or polarization mode. For example, 1 represents the switch element being on, and 0 represents the switch element being off. The pattern of the switch element of a 100*100 reflecting unit is a 100*100-dimensional 01 bit matrix.

[0116] Preferably, a limited number of patterns of the switch element of the reflecting unit or the refracting unit of the smart surface can be agreed, as shown in Table 1, wherein each pattern is a 100*100-dimensional 01 bit matrix. In this way, the amount of information interaction can be reduced. The shape or direction of the reflecting wave or the refracting wave of the smart surface corresponding to each pattern can be different.

[0117] Table 1

[0118]

[0119] In an embodiment of the present application, a limited number of working modes of the third node device can be agreed to reduce the amount of information interaction, as shown in Table 2, and the shape or direction of the reflecting wave or the refracting wave corresponding to each mode can be different. The working mode of the third node device includes at least one of the following:

[0120] Covering one direction at one time;

[0121] Covering two directions at one time.

[0122] Covering one direction at one time can mean shaping one main direction at one time. Covering two directions at one time can mean shaping two main directions at one time.

[0123] Specifically, covering two directions at one time means that the third node device shapes two directions at one time, or means that part of the third node device works in the mode of direction 1, and the other part works in the mode of direction 2 at the same time.

[0124] Table 2

[0125]

[0126] The phase-related information can be the phase information of each reflecting unit or refracting unit in the third node device.

[0127] The amplitude-related information can be the amplitude information of each reflecting unit or refracting unit in the third node device.

[0128] The polarization mode related information can be polarization mode information of each reflecting unit or refracting unit in the third node device.

[0129] The frequency related information can be frequency information of the third node device, for example, the third node device supports two frequency bands at the same time, and the frequency related information indicates information of one of the frequency bands.

[0130] The information transmission method, the first node device and the second node device determine the working information of the third node device after negotiating the target information, so that the third node device works according to the unified working information, and the problem that the smart surface cannot simultaneously execute different working commands of two nodes on the smart surface is solved.

[0131] Further, after the working information of the third node device is determined, the method further includes:

[0132] The determined working information of the third node device is sent to the third node device.

[0133] Further, the working information is periodic working information or the working information is aperiodic working information.

[0134] Optionally, when the working information is aperiodic working information, the working information further includes at least one of the following:

[0135] time information corresponding to the identification information;

[0136] time information corresponding to the switch information;

[0137] time information corresponding to the phase related information;

[0138] time information corresponding to the amplitude related information;

[0139] time information corresponding to the polarization mode related information.

[0140] The time information includes at least one of a start time, an end time and a duration, and the time granularity of the time information can be a time slot (slot) or a millisecond (ms).

[0141] Optionally, when the working information is periodic working information, the working information further includes N groups of bits; N is the number of time units included in one period of the working information, and the N groups of bits correspond to N time units one by one; wherein each group of bits is used to indicate at least one of the following information in the corresponding time unit:

[0142] a working mode;

[0143] switch information of a switch element;

[0144] phase related information;

[0145] amplitude related information;

[0146] polarization related information;

[0147] N is an integer greater than or equal to 1, and the number of bits contained in each group of bits is determined according to the number of switch information.

[0148] Taking the above working mode as an example, it is assumed that the working mode of the third node device includes two working modes, 0 represents working mode 1, and 1 represents working mode 2; the working information adopts a bitmap mode, for example, the first information is 11011, and each bit position represents a time unit, 11011 represents that in the first, second, fourth and fifth time units within 5 time units, the working mode 1, and the third time unit is working mode 2.

[0149] Further, the working mode includes: a first working mode on at least one downlink time resource, and a second working mode on an uplink time resource corresponding to the at least one downlink time resource.

[0150] The second working mode is one of the first working mode.

[0151] In specific embodiments of the present application, the above-mentioned time resource can be a time slot (slot) or a subframe or ms, etc. For example, taking a frequency band FR2 and a time division duplex (TDD) system as an example, the above-mentioned at least one working mode can be as shown in Table 3:

[0152] Table 3

[0153] slotDLDLDLDLULDLDLDLDLULWorking mode0012100122Bit indication00000110010000011010

[0154] Through Table 3, the working mode matching of the downlink slot and the uplink slot in a period can be realized, for example, the downlink slot in a period has working modes 1 and 2, and then the uplink slot also has working modes 1 and 2.

[0155] Further, as a first optional implementation, the above-mentioned target information negotiated with the second node device includes:

[0156] sending the first information to the second node device;

[0157] receiving third information sent by the second node device, the third information comprising at least one of the second information and feedback information of the first information.

[0158] Further, the determining the working information of the third node device according to the target information comprises:

[0159] In a case where the third information comprises the feedback information of the first information and the feedback information of the first information is ACK information, the working information of the third node device is determined as the first information.

[0160] In the embodiment of the present application, the ACK information indicates that the first node device and the second node device negotiate the consistent working information.

[0161] In a case where the third information only comprises the feedback information of the first information and the feedback information of the first information is NACK information;

[0162] After the receiving the third information sent by the second node device, the method further comprises:

[0163] sending fourth information to the second node device;

[0164] receiving feedback information of the fourth information sent by the second node device;

[0165] The fourth information is the working information of the third node device expected by the first node device, and the fourth information is different from the first information.

[0166] Further, the determining the working information of the third node device according to the target information comprises:

[0167] In a case where the feedback information of the fourth information is ACK information, the working information of the third node device is determined as the fourth information.

[0168] In a case where the feedback information of the fourth information is NACK, the first node device and the second node device continue to negotiate (perform information interaction) until the first node device and the second node device negotiate the consistent working information.

[0169] Further, in a case where the third information comprises the second information and the feedback information of the first information, and the feedback information of the first information is NACK information; or in a case where the third information only comprises the second information;

[0170] After the receiving the third information sent by the second node device, the method further comprises:

[0171] sending feedback information of the second information to the second node device.

[0172] Further, the determining the working information of the third node device according to the target information comprises:

[0173] In a case that the feedback information of the second information is ACK, the working information of the third node device is determined as the second information.

[0174] Here, the feedback information of the second information is ACK, which means that the first node device agrees to determine the second information as the working information of the third node device, that is, the first node device and the second node device negotiate to determine the second information as the working information of the third node device.

[0175] In a case that the feedback information of the second information is NACK, the first node device and the second node device continue to negotiate (exchange information) until the first node device and the second node device negotiate to determine the same working information.

[0176] Further, as a second optional implementation, the negotiating the target information with the second node device comprises:

[0177] receiving the second information sent by the second node device;

[0179] The fourth information is the working information of the third node device expected by the first node device, and the fourth information is different from the first information.

[0180] Here, in a case that the feedback information of the second information is ACK, the working information of the third node device is determined as the second information.

[0181] Further, in a case that the fifth information only comprises the feedback information of the second information and the feedback information of the second information is NACK, or in a case that the fifth information only comprises the fourth information, or in a case that the fifth information comprises the feedback information of the second information and the fourth information and the feedback information of the second information is NACK information;

[0182] After the sending the fifth information to the second node device, the method further comprises:

[0184] The seventh information is working information of a third node device expected by the second node device, and the seventh information is different from the second information.

[0185] In the embodiment of the present application, the NACK information indicates that the first node device and the second node device have not agreed on the working information, and the feedback information of the second information is NACK, which indicates that the first node device does not agree to determine the second information as the working information of the third node device, and the two need to continue to negotiate. Then, the second node device sends the sixth information to the first node device.

[0186] In the case that the fourth information is included in the sixth information, and the feedback information of the fourth information is ACK, it indicates that the second node device agrees to determine the fourth information as the working information of the third node device.

[0187] In the case that the fourth information is included in the sixth information, and the feedback information of the fourth information is NACK, it indicates that the second node device does not agree to determine the fourth information as the working information of the third node device, and the two need to continue to negotiate.
