[0002] The present application relates to the field of communication, and in particular, to a communication method and related apparatus. BACKGROUND
[0003] Wireless communication can be transmission communication between two or more communication devices without propagation through a conductor or cable. Generally, the two or more communication devices include a network device and a terminal device, or the two or more communication devices include different terminal devices.
[0004] Currently, in the communication process of different communication devices, a signal sender can send a measurement signal (e.g., a reference signal), accordingly, a signal receiver can receive the measurement signal and measure the related information of the channel (e.g., the interference information of the channel) based on the measurement signal, and subsequently, resource management can be implemented based on the related information of the channel.
[0005] However, in the above measurement process, how to improve the measurement performance is a technical problem to be solved. SUMMARY
[0006] The present application provides a communication method and related apparatus for improving the accuracy of interference measurement and thus improving the communication performance.
[0007] The first aspect of the present application provides a communication method, which is applied to a first communication device, such as being executed by the first communication device. The first communication device can be a communication device (e.g., a terminal device or a network device), or the first communication device can be a part of the communication device (e.g., a circuit or a chip responsible for communication functions (e.g., a Modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core)), or the first communication device can also be a logic module or software that can realize all or part of the functions of the communication device.
[0008] In the method, the first communication device receives first information, which is used to configure a first resource, and the first resource is used for interference measurement; and the first communication device performs measurement based on the first resource.
[0009] Based on the above scheme, the first information received by the first communication device is used to configure the first resource, which is used for interference measurement, and thereafter the first communication device can perform measurement based on the first resource. In this way, the first communication device can perform interference measurement based on the first resource specified by the first information, which can improve the accuracy of interference measurement and thus improve communication performance.
[0010] Optionally, the resource pattern of the first resource satisfies at least one of the following: the resource pattern of the first resource includes the 0th, 4th and 8th subcarriers in a frequency domain unit; or the resource pattern of the first resource includes the 1st, 5th and 9th subcarriers in a frequency domain unit; or the resource pattern of the first resource includes the 0th, 1st, 6th and 7th subcarriers in a frequency domain unit; or the resource pattern of the first resource includes the 2nd, 3rd, 8th and 9th subcarriers in a frequency domain unit; or the resource pattern of the first resource includes the 4th, 5th, 10th and 11th subcarriers in a frequency domain unit; or the resource pattern of the first resource includes the 0th, 1st, 2nd, 3rd, 6th and 7th, 8th and 9th subcarriers in a frequency domain unit; or the resource pattern of the first resource includes the 0th, 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th and 11th subcarriers in a frequency domain unit.

[0012] It should be understood that the first resource can be used for interference measurement. For example, the first resource can be a channel state information interference measurement (CSI-IM) resource, or the first resource can be another name specified by a standard / protocol, which is not limited here.
[0013] Optionally, the first resource is a zero-power interference measurement resource. The first resource measured by the first communication device can be a zero-power interference measurement resource, i.e., no other signal can be carried on the first resource, so that the interference measurement result information measured by the first communication device can reflect the interference situation caused by the interference signal on the interference measurement resource. For example, the first resource can be a zero-power channel state information reference signal (ZP CSI-RS) resource.
[0014] Optionally, the first resource is a non-zero-power interference measurement resource. The first resource measured by the first communication device can be a non-zero-power interference measurement resource, i.e., a non-zero-power signal can be carried on the first resource, so that the interference measurement result information measured by the first communication device can reflect the interference situation caused by the non-zero-power signal on the interference measurement resource. For example, the first resource can be a non-zero-power channel state information reference signal (NZP CSI-RS) resource.

[0017] Optionally, the above resource management can include radio resource management (RRM), data transmission, etc. For example, the RRM includes one or more of cell selection and reselection, power control, access control, handover management, load control, frequency allocation (e.g., carrier aggregation (CA) related configuration, including but not limited to activating and deactivating carrier aggregation, configuring aggregated carrier set, allocating resource block, etc.), channel allocation, and interference management.
[0018] Optionally, the first communication device can not send the second information.

For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.
[0099] (5) In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.
[0100] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.
[0101] It can be understood that the information may be processed as necessary between the source and the destination of the information transmission, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.
[0102] (6) In embodiments of the present application, "indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. Information indicated by certain information (indication information described below) is referred to as to-be-indicated information. In a specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and other parts of the to-be-indicated information are known or agreed in advance. For example, the indication of specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, predefined by a protocol), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that the indication information can be used to indicate the to-be-indicated information for a sender of the indication information, and the indication information can be used to determine the to-be-indicated information for a receiver of the indication information.
[0103] In the present application, the same or similar parts between various embodiments can be mutually referred to, unless otherwise specified. In various embodiments of the present application, and various implementation manners / implementation methods / implementation approaches in each embodiment, if there is no special specification and no logical conflict, the terms and / or descriptions between different embodiments, and between various implementation manners / implementation methods / implementation approaches in each embodiment are consistent and can be mutually referred to, and the technical features in different embodiments, and in various implementation manners / implementation methods / implementation approaches in each embodiment can be combined to form new embodiments, implementation manners, implementation methods, or implementation approaches according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.
[0104] In order to facilitate understanding of the method provided by the embodiments of the present application, the system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is to more clearly illustrate the scheme of the embodiments of the present application, and does not constitute a limitation on the scheme provided by the embodiments of the present application.
[0105] In a possible implementation, the present application can be applied to a Narrow Band-Internet of Things (NB-IoT) system, an integrated sensing and communication (ISAC) communication system, a wireless local area network (WLAN), a short-range wireless communication system (such as a sidelink, wireless fidelity (Wi-Fi or WiFi), Bluetooth, and the like), a wired network, a vehicle to everything (V2X) communication system, a device-to-device (D2D) communication system, a vehicle networking communication system, a 4th generation (4G) mobile communication system (such as a long term evolution (LTE) system), an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a 5th generation (5G) mobile communication system (such as a new radio (NR) system), a future evolved new radio (NR) wireless communication system, or other similar communication systems, and the like, without limitation. For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and a future OFDM system and an OFDM-like system, for example, the present application can be applied to three major application scenarios of the next generation 5G mobile communication system: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and / or enhanced machine type communication (eMTC).
[0106] Referring to FIG. 1a, an architecture of a communication system 1000 to which embodiments of the present application can be applied is shown. As shown in FIG. 1a, the communication system includes a RAN 100 and a core network 200, and optionally, the communication system 1000 can further include an Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b, collectively denoted as 110 in FIG. 1a) and at least one terminal (e.g., 120a-120j, collectively denoted as 120 in FIG. 1a). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1a). The terminal 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is connected to the core network 200 through wire or wireless. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical function of the core network device and the logical function of the RAN node. The terminals can be connected to each other and the RAN nodes can be connected to each other through wire or wireless.
[0107] FIG. 1b shows an example of an O-RAN system, which can include other components than those shown in the figure. As shown, an access network device (such as a RAN device, which can be an eNB or a gNB or a next generation access network device) communicates with a core network (CN) over a backhaul and communicates with a UE over an air interface.
[0108] In a possible implementation, the present application can be applied to a long term evolution (LTE) wireless communication system, an NR wireless communication system, and a future evolved new radio (NR) wireless communication system. For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and a future OFDM system and an OFDM-like system, etc.
[0109] As an example, the RAN node can be a satellite base station or a satellite, which is explained below in connection with FIGS. 1c-1g. FIGS. 1c and 1d are schematic diagrams of a communication system suitable for embodiments of the present application.
[0110] As shown in FIGS. 1c and 1d, the satellite base station provides communication services for the terminal. For example, the satellite base station transmits downlink data to the terminal, where the data is encoded using channel coding, and the channel-coded data is transmitted to the terminal after being modulated by constellation modulation. For another example, the terminal transmits uplink data to the satellite base station, where the uplink data can also be encoded using channel coding, and the encoded data is transmitted to the satellite base station after being modulated by constellation modulation. In addition, as shown in FIG. 1d, the satellite base station can also communicate with the ground base station, that is, the satellite can act as a base station, and also as a terminal.
[0111] In this application, the satellite can refer to a drone, a hot air balloon, a low-orbit satellite, a medium-orbit satellite, a high-orbit satellite, etc. The satellite can also refer to a non-ground base station or a non-ground device, etc.
[0112] It should be understood that the present application can be applied to a scenario in which network devices communicate with each other, and the scenario shown in FIG. 1d can also be regarded as an example of network devices communicating with each other, where the satellite and the base station can both be regarded as a network device.
[0113] As an implementation manner, the present application can be applied to a satellite inter-satellite link communication system. For example, the communication between satellite #1 and satellite #2 shown in FIG. 1d.
[0114] As shown in FIG. 1e, the satellite inter-satellite link communication system can be divided into two parts: an acquisition pointing tracking (APT) subsystem (including an APT module and an APT transmitter / receiver) and a communication subsystem (including a communication module and a transceiving antenna). The communication subsystem is mainly responsible for the transmission of inter-satellite information, and is the main body of the inter-satellite communication system; the APT system is mainly responsible for the acquisition, alignment and tracking between satellites. The direction of arrival of the incident signal can be determined, which is used for acquisition and adjustment of the direction of the transmitted wave aiming at the receiving direction, which is used for alignment. In the whole communication process, the APT is constantly adjusted for alignment and acquisition, which is used for tracking. In order to minimize the influence of attenuation and interference in the channel, while requiring high confidentiality and transmission rate, the APT must be adjusted in real time to adapt to changes constantly.
[0115] It should be understood that the current APT system is an optical system, which has the disadvantage of difficult optical alignment and the need for mechanical adjustment of the pointing direction. The current communication subsystem is mostly an optical communication system, and there are also some microwave band systems, which mostly use a single high-gain antenna. The current APT system and the communication subsystem are independent systems. The disadvantage is that optical communication is easily affected by vibration, etc., and the rate is unstable; the frequency of millimeter wave is low, the communication capacity is low, and the antenna needs to be mechanically adjusted for pointing.
[0116] As another implementation manner, the present application can be applied to a scenario in which terminal devices communicate with each other, for example, an Internet of Things communication system.
[0117] FIG. 1f is a schematic diagram of a wireless screen projection of an Internet of Things, which is applicable to the embodiments of the present application. A terminal device (for example, a smart phone) establishes a network connection with a television set. The smart phone transmits content that needs to be projected and displayed on the television set to the television set. After receiving the content transmitted by the smart phone, the television set displays the content on its display screen.
[0118] It should be understood that the screen projection scenario shown in FIG. 1f can be regarded as an example of terminal device-to-terminal device communication, in which the smart phone and the television set can both be regarded as a terminal device.
[0119] As yet another implementation manner, the present application can be applied to an integrated access and backhaul (IAB) system.
[0120] FIG. 1g is a schematic diagram of an IAB system, which is applicable to the embodiments of the present application. As shown in FIG. 1g, the IAB can include an IAB donor, an IAB node and a terminal. The link between the IAB donor and the IAB node is a backhaul link, and the link between the terminal and the IAB node is an access link. The present application can be applied to both parties of communication in the backhaul link, or both parties of communication in the access link.
[0121] It should be understood that the above-mentioned system application scenarios are only examples, and the present application can also be applied to other scenarios, which are not listed one by one here.
[0122] In a wireless communication system (for example, the system shown in any one of FIGS. 1a to 1g), the wireless communication resource generally includes time-frequency resources. In the following, the time-frequency resources will be introduced taking the NR system as an example. It should be understood that NR can be replaced by 5G or 5G NR.
[0123] 1. Numerology.
[0124] 5G NR introduces the concept of Numerology, which includes sub-carrier spacing (SCS), and corresponding parameters such as symbol length, cycle prefix (CP) length, etc. Since there is a certain mapping relationship between SCS and symbol length, CP length, SCS is often used instead of Numerology in some documents.
[0125] For example, the parameters involved in Numerology are shown in Table 2.
[0126] Table 2
[0127] In Table 2, μ represents a subcarrier spacing index, or μ represents a numerology, CP length includes normal (Normal) CP length and extended (Extended) CP length, and FR represents a frequency range (FR).
[0128] 2. Frame structure.
[0129] In the NR system, the unit in the time domain includes a symbol, a slot, a subframe, a half frame, a frame, etc., wherein the time of one frame is 10 ms, one frame can be divided into 10 subframes numbered 0-9, and the subframes numbered 0-4 form one half frame, and the subframes numbered 5-9 form another half frame. The time of each subframe is 1 ms. Each subframe can include one or more slots, and each slot includes 14 symbols under normal CP and includes 12 symbols under extended CP.
[0130] For example, the number of slots included in each subframe is related to the SCS, and the association is shown in Table 3.
[0131] Table 3
[0132] As shown in the example of FIG. 2a, it is a schematic diagram of a frame structure of 5G NR, which includes:
[0133] Frame: The length is fixed at 10 ms, and the frame number range is 0-1023.
[0134] Subframe: The length is fixed at 1 ms, and the subframe number range is 0-9.
[0135] Slot: When normal CP is used, the length is 14 symbols. Since the symbol length is not fixed, the slot length is also not fixed. When the SCS is 60 kHz, extended CP can also be used, and the slot length is 12 symbols. Optionally, the slot is the smallest unit of data scheduling.
[0136] Symbol: The length is not fixed and is related to the SCS. Optionally, the symbol is the basic unit of modulation.
[0137] Generally, in the physical layer, one symbol can contain a plurality of sampling points, and the sampling point can be the smallest time unit of the physical layer.
[0138] In addition, the scheduling time unit on the 5G NR data domain is a slot, the number of symbols contained in the slot is fixed, but the length of the symbol is related to the SCS. In the following, taking SCS of 30 kHz and 120 kHz as examples, the relationship between the frame, subframe, slot and symbol will be exemplarily described.
[0139] As shown in the examples of FIG. 2b and FIG. 2c, the relationship between the frame, subframe, slot and symbol corresponding to SCS of 30 kHz and 120 kHz respectively.
[0140] 3. Symbol type and slot format.
[0141] Generally, OFDM symbols include three types, which are:
[0142] Downlink (D): used for downlink transmission.
[0143] Uplink (U): used for uplink transmission.
[0144] Flexible (F): can be used for uplink transmission, can also be used for downlink transmission, and can also be used as a guard period (GP) or reserved resource.
[0145] Optionally, each slot can be freely combined by the three types of symbols to form various slot formats.
[0146] As shown in the example of FIG. 2d, according to the protocol-defined slot format, the slot type can be divided into four cases (Case).
[0147] Case 1: only contains “D” symbols, which is also commonly referred to as a downlink-only slot (DL-only slot).
[0148] Case 2: only contains “U” symbols, which is also commonly referred to as a downlink-only slot (UL-only slot).
[0149] Case 3: only contains “F” symbols, which is also commonly referred to as a flexible-only slot (Flexible-only slot).
[0150] Case 4: a slot contains at least one “D” or “U” symbol, and there is also an “F” symbol in the slot.
[0151] In addition, as shown in FIG. 2d, Case 4 can be further divided into several sub-cases.
[0152] Case 4-1: a slot contains more “D” symbols and fewer “F” symbols.
[0153] Case 4-2: One slot contains more "U" symbols and less "F" symbols.
[0154] Case 4-3: One slot contains more "D" symbols and less "F" and "U" symbols.
[0155] Case 4-4: One slot contains more "U" symbols and less "F" and "D" symbols.
[0156] Case 4-5: One slot contains alternating "D", "F" and "U" symbols.
[0157] As can be seen from the above examples, the slot format design of 5G NR can achieve uplink and downlink data changes at the symbol level, while LTE usually only achieves changes at the subframe level. This design is more flexible and also makes the slot type more diverse to adapt to different types of services in different scenarios.
[0158] 4. Self-contained slot.
[0159] Case 4-3, Case 4-4 and Case 4-5 in FIG. 2d are also called self-contained slots, which correspond to two structures of self-contained slots, respectively.
[0160] One structure is a DL-dominant slot: Case 4-3 in FIG. 2d, in which the slot is mainly used for downlink data transmission, and a small number of symbols are used for transmitting uplink control signals (such as hybrid automatic repeat request (HARQ) feedback of the downlink data) or sounding reference signals (SRS) through time division multiplexing, thereby shortening the downlink HARQ feedback delay.
[0161] Another structure is a UL-dominant slot: Case 4-4 in FIG. 2d, in which the slot is mainly used for uplink data transmission, and a small number of symbols are used for transmitting downlink control signals (such as uplink scheduling indication in the physical downlink control channel (PDCCH)) through time division multiplexing, thereby shortening the uplink scheduling delay.
[0162] Generally, in the design of self-contained slot, both network device and terminal device can switch uplink and downlink transmission in one slot, and ensure normal work after switching by reserving guard time and not transmitting or receiving any signal in the guard time.
[0163] 5. Mini-slot.
[0164] In order to further reduce the air interface delay, the protocol proposes the concept of micro-slot, whose time domain length can be less than 14 symbols. Compared with the scheduling of basic slots, the division in time domain of micro-slots is more fine-grained, and the scheduling delay is also shorter. The scheduling of micro-slots is usually also called non-slot based scheduling.
[0165] 6. Frequency domain resource.
[0166] Resource element (RE) is the smallest physical layer resource of 5G NR, which is 1 subcarrier in frequency domain and 1 OFDM symbol in time domain.
[0167] Resource block (RB) is the basic unit of channel resource allocation in frequency domain of 5G NR, and one RB can contain 12 subcarriers in frequency domain. Since the subcarrier spacing in 5G NR is variable, the actual bandwidth of RB is also variable.
[0168] Resource grid (RG) is a set of time-frequency resources, which is defined as follows in 5G NR: for different numerologies on each carrier, an RG is a set of resources of all subcarriers in frequency domain and all symbols in time domain with a length of one subframe, and the starting point of frequency domain is in RB granularity. Since different numerologies correspond to different SCS, and one RB contains 12 subcarriers, for the same transmission bandwidth, the number of RBs contained in RG is different under different numerologies. RG is one subframe in time domain. Meanwhile, uplink and downlink RGs are defined respectively.
[0169] As shown in FIG. 2e, it is a schematic diagram of one implementation of resource division of RE, RB and RG. In FIG. 2e, one subframe in time domain can include a plurality of OFDM symbols; one resource element represents a resource of 1 subcarrier in frequency domain and 1 OFDM symbol in time domain; one resource block contains 12 subcarriers in frequency domain; and resource grid represents a set of time-frequency resources.
[0170] Common resource block (CRB) can be understood as a general term for all RBs in 5G NR, numbered from 0, and the center frequency point of the 0th subcarrier in CRB0 is also Point A.
[0171] Physical resource block (PRB) refers to the RBs contained in the bandwidth part (BWP) of a certain UE in 5G NR, also numbered from 0, and is the basic unit of data channel scheduling.
[0172] Resource block group (RBG) refers to the combination of a number of PRBs within the bandwidth part (BWP), also numbered from 0, and is the basic unit of data channel scheduling. An RBG can contain {2, 4, 8, 16} PRBs, and the specific number is related to the number of RBs in the BWP and the configuration options.
[0173] Resource element group (REG) is the basic unit of control channel resources. 1 REG is 12 subcarriers in the frequency domain, i.e. the width of one RB, and 1 OFDM symbol in the time domain.
[0174] Control channel element (CCE) is the basic unit of control channel resource scheduling, and 1 CCE is composed of 6 REGs in the frequency domain.
[0175] As shown in FIG. 2f, it is a schematic diagram of the relationship between REG and CCE.
[0176] As described above, the definition of time-frequency resources in NR, the same definition can be used in future networks, or different definitions can be used. For example, future networks can define multiple subcarrier spacings, not limited to SCS in 5G. A slot can include one or more symbols, and an RB can include one or more subcarriers, etc.
[0177] 7. Sending or receiving
[0178] Physical reception link control channel (PRxCCH): is a kind of physical layer control channel, generally, the standard protocol is described from the perspective of terminal equipment, that is, the physical layer control channel received by the terminal equipment, which is similar to the PDCCH in LTE and 5G. PRxCCH can be a new physical layer control channel introduced in the next generation communication system (such as 6G). Of course, 6G may still use PDCCH to represent the physical downlink control channel or physical transmission link control channel of the terminal equipment.
[0179] Physical reception link shared channel (PRxSCH): is a kind of physical layer data channel, generally, the standard protocol is described from the perspective of terminal equipment, that is, the physical layer data channel received by the terminal equipment, which is similar to the PDSCH in LTE and 5G. PRxSCH can be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PDSCH to represent the physical downlink data channel or physical reception link data channel of the terminal equipment.
[0180] Physical transmission link control channel (PTxCCH): is a kind of physical layer control channel, generally, the standard protocol is described from the perspective of terminal equipment, that is, the physical layer control channel transmitted by the terminal equipment, which is similar to the PUCCH in LTE and 5G. PTxCCH can be a new physical layer control channel introduced in 6G. Of course, future communications such as 6G may still use PUCCH to represent the physical uplink control channel or physical transmission link control channel of the terminal equipment.
[0181] Physical transmission link Shared Channel (PTxSCH): a kind of physical layer data channel, generally, the standard protocol is described from the perspective of terminal equipment, that is, the physical layer data channel sent by the terminal equipment, the function is similar to the Physical Uplink Shared Channel (PUSCH) in LTE and 5G. PTxSCH can be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PUSCH to represent the physical uplink data channel or physical reception link data channel of the terminal equipment.
[0182] Optionally, for downlink, it can be described as receiving from the perspective of terminal equipment; for uplink, it can be described as transmitting from the perspective of terminal equipment.
[0183] At present, in the communication process of different communication devices, the signal sender can send a measurement signal (for example, a reference signal), accordingly, the signal receiver can receive the measurement signal and measure the related information of the channel (for example, the interference information of the channel) based on the measurement signal, and subsequently, the resource management can be implemented based on the related information of the channel. However, in the above measurement process, how to improve the measurement performance is a technical problem to be solved.
[0184] In some implementation examples, the network device can configure NZP CSI-RS resource to measure the channel, and ZP CSI-RS to measure the interference, wherein the ZP CSI-RS resource can also be referred to as CSI-IM resource.
[0185] As shown in the example of FIG. 2g, it is a schematic diagram of the CSI-IM resource of the LTE system. In FIG. 2g, each box represents an RE, 2 symbols in time domain and 12 subcarriers represent 24 REs. Taking the transmission of 4-port CSI-RS by CSI-IM resource as an example, that is, the LTE CSI-IM pattern in the figure. In time domain, the CSI-IM resource includes two symbols in time; in frequency domain, the CSI-IM resource includes two subcarriers in frequency; the CSI-IM resource occupies 4 REs (that is, the 4 REs corresponding to the black filled boxes) of 24 REs.
[0186] As shown in the example of FIG. 2h, it is a schematic diagram of the CSI-IM resource of the NR system. In FIG. 2h, taking the transmission of 4-port CSI-RS by CSI-IM resource as an example, it contains the following two patterns:
[0187] NR CSI-IM pattern 0, in time domain, the CSI-IM resource includes two symbols which are continuous in time; in frequency domain, the CSI-IM resource includes two subcarriers which are continuous in frequency; 4 REs are occupied.
[0188] NR CSI-IM pattern 1, in time domain, the CSI-IM resource includes one symbol which is continuous in time; in frequency domain, the CSI-IM resource includes four subcarriers which are continuous in frequency; 4 REs are occupied.
[0189] Generally, the CSI-IM resource only measures the interference power, and the interference power is considered when calculating the CQI. When calculating the interference power, the terminal device considers that the received power of the 4 REs (for example, the 4 REs in FIG. 2g or FIG. 2h) in the CSI-IM pattern is under the same channel interference, that is, the received power is averaged.
[0190] In addition, the configuration of the CSI-RS can include continuous frequency domain resources, for example, the network device can indicate the starting RB and the number of RBs. In different RBs, the CSI-IM pattern in each RB is the same. In the above process, the terminal device will use the interference measurement averaging method to measure the interference on the different frequency domain resources configured by the CSI-IM resource, which can include different RBs or different REs (for example, the 4 REs in FIG. 2h) in one RB.
[0191] However, in the CSI-IM resource, the channel conditions corresponding to different frequency domain resources can be different, which leads to inaccurate interference measurement corresponding to the above interference measurement averaging method, and further affects the communication performance.
[0192] To solve the above problems, the present application provides a communication method and related devices, which will be described in detail below in combination with the drawings.
[0193] Please refer to FIG. 3, which is an implementation schematic diagram of the communication method provided by the present application, and the method includes the following steps.
[0194] It should be understood that, in the following, the first communication device and the second communication device in FIG. 3 are taken as an example to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the first communication device and / or the second communication device can be a communication device, or a chip, a baseband chip, a modem chip, a SoC chip containing a modem core, a SIP chip, a communication module, a chip system, a processor, a logic module or software in the communication device, etc. Optionally, the communication device can be a terminal device or a network device (for example, the network device can be an access network device, an access network element, etc.).
[0195] As an example, the first communication device can be a terminal device and the second communication device can be a network device, or both the first communication device and the second communication device are network devices. For example, the network device can be an access network device, a communication device (e.g., at least one of a CU, a DU, a RU) in an ORAN system.
[0196] As another example, both the first communication device and the second communication device are terminal devices, i.e., the scheme shown in FIG. 3 can be applied to a sidelink communication scenario.
[0197] S301. The second communication device sends first information, and correspondingly, the first communication device receives the first information. The first information is used to configure a first resource, and the first resource is used for interference measurement.
[0198] S302. The first communication device performs measurement based on the first resource.
[0199] It should be understood that the first information used to configure the first resource can be understood as the first information used to indicate the first resource, or the first information used to determine the first resource, etc.
[0200] Optionally, the first information can be physical layer signaling, such as downlink control information (DCI), or the first information can be high layer signaling, such as RRC signaling or MAC signaling, etc.
[0201] It should be understood that the first resource can be used for interference measurement. For example, the first resource can be a channel state information interference measurement (CSI-IM) resource, or the first resource can be another name specified by a standard / protocol, which is not limited here.
[0202] Optionally, the first resource is a zero-power interference measurement resource. The first resource measured by the first communication device can be a zero-power interference measurement resource, i.e., no other signal can be carried on the first resource, so that the interference measurement result information measured by the first communication device can reflect the interference situation caused by the interference signal on the interference measurement resource. For example, the first resource can be a zero-power channel state information reference signal (ZP CSI-RS) resource.
[0203] Optionally, the first resource is a non-zero-power interference measurement resource. The first resource measured by the first communication device can be a non-zero-power interference measurement resource, i.e., a non-zero-power signal can be carried on the first resource, so that the interference measurement result information measured by the first communication device can reflect the interference situation caused by the non-zero-power signal on the interference measurement resource. For example, the first resource can be a non-zero-power channel state information reference signal (NZP CSI-RS) resource.
[0204] Based on the scheme shown in FIG. 3, the first information received by the first communication device in step S301 is used to configure a first resource for interference measurement, and thereafter, the first communication device can perform measurement based on the first resource in step S302. In this way, the first communication device can perform interference measurement based on the first resource specified by the first information, which can improve the accuracy of interference measurement and thus improve communication performance.
[0205] In one possible implementation of the method shown in FIG. 3, the first resource is used for interference measurement of the first radio access technology, and the resource pattern of the first resource is the same as the pattern of the reference signal of the second radio access technology. Specifically, in addition to being used for interference measurement of the first radio access technology, the resource pattern of the first resource is the same as the pattern of the reference signal of the second radio access technology, so that the above scheme can be applied to a scenario of spectrum sharing of two or more radio access technologies (e.g., multi-radio access technology spectrum sharing (MRSS)), and improve the accuracy of interference measurement in this scenario and thus improve communication performance.
[0206] For example, the first radio access technology can be a future network, including but not limited to 6G, 5.5G, the next generation network of 5G, etc. The second radio access technology can be NR / 5G / 5G NR, 4G, LTE, etc.
[0207] For example, the reference signal of the second radio access technology includes at least one of the following: PBCH DMRS, PDCCH DMRS, or PDSCH DMRS.
[0208] It should be noted that the resource pattern of the first resource can be implemented in various ways, and some possible implementation ways will be exemplarily described below, which can be at least one of the following ways.
[0209] In the first way, the resource pattern of the first resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in a frequency domain unit.
[0210] In the first way, the resource pattern of the first resource is the same as the resource pattern of the PBCH DMRS of the second radio access technology, and accordingly, in step S302, the process of the second communication device performing measurement based on the first resource can implement interference measurement on the PBCH DMRS of the second radio access technology to improve the accuracy of interference measurement.
[0211] In addition, the PBCH DMRS of the second radio access technology can be regarded as part of a synchronization signal (SS), and therefore, the above technical solution can also achieve interference measurement on the synchronization signal of the second radio access technology, so as to improve the accuracy of interference measurement.
[0212] Optionally, the SS can include a synchronization signal / physical broadcast channel block (SS / PBCH block, or SSB for short), a primary synchronization signal (PSS), a secondary synchronization signal (SSS), or other signals for synchronization specified in future standards / protocols.
[0213] In this application, a frequency domain unit can indicate one or more resources in the frequency domain, including one or more subcarriers, one or more subcarrier groups, one or more resource blocks, one or more physical resource blocks, one or more resource block groups, one or more partial bandwidths, or other implementation manners specified in standards / protocols. In the following examples, one resource block (RB) is taken as an example for illustration.
[0214] Exemplarily, one frequency domain unit can be one resource block. One resource block can include one or more subcarriers, such as 12 subcarriers.
[0215] As shown in the example of FIG. 4a, in mode one, the RBs on each of the one or more symbols share 12 subcarriers, and the indexes of the subcarriers are 0, 1, 2, …, and 11. In FIG. 4a, the resource pattern of the first resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit on one symbol. In other words, the first resource can include 3 REs in FIG. 4a.
[0216] Optionally, the ith frequency domain unit in this application can refer to the frequency domain unit i, or the frequency domain unit corresponding to the frequency domain unit number i. For example, the ith subcarrier can refer to the subcarrier i, or the subcarrier corresponding to the subcarrier number i.
[0217] As shown in the example of FIG. 4b, in the first manner, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarriers 0, 1, 2, …, 11. In FIG. 4b, the resource pattern of the first resource includes partial positions on three consecutive symbols (symbol indices 0, 1, and 2, respectively), i.e., the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit on the 0th symbol (such as symbol 0); and the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit on the 2nd symbol (such as symbol 2). In other words, the first resource can include 6 REs in FIG. 4b.
[0218] Optionally, the ith time domain unit in the present application can refer to a time domain unit i, or a time domain unit corresponding to the time domain unit number i. For example, the ith symbol can refer to a symbol i, or a symbol corresponding to the symbol number i.
[0219] In the second manner, the resource pattern of the first resource includes the 1st subcarrier (such as subcarrier 1), the 5th subcarrier (such as subcarrier 5), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit.
[0220] In the second manner, the resource pattern of the first resource is the same as the resource pattern of the PDCCH DMRS of the second radio access technology, and accordingly, in step S302, the process of measuring by the second communication device based on the first resource can implement interference measurement on the PDCCH DMRS of the second radio access technology, to improve the accuracy of the interference measurement.
[0221] As shown in the example of FIG. 4c, in the second manner, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarriers 0, 1, 2, …, 11.

[0244] From the manner one to the manner three, the first communication device can perform the interference measurement based on the first resource of the resource pattern specified by the first information in step S302, interference measurement on the signal of one or more specified resource patterns can be realized, the accuracy of the interference measurement can be improved, and the communication performance can be improved.
[0245] In a possible implementation, the first information received by the first communication device in step S301 includes at least one of the following: configuration information of the resource pattern of the first resource, time domain configuration information of the first resource, or frequency domain configuration information of the first resource. Thus, at least one of the resource pattern, the time domain, and the frequency domain can be configured. The configuration information will be introduced in combination with some implementation examples.
[0246] As an example, the time domain configuration information of the first resource included in the first information includes any of the following: bitmap information, a starting time domain unit index of the first resource, or a time domain unit quantity of the first resource; the bitmap information is used to indicate the time domain resource included in the first resource.
[0247] Optionally, the time domain resource included in the first resource can be one or more time units, which can be a frame, a subframe, a time slot, a sub-time slot, a symbol, a symbol group, etc.
[0248] For example, in the case where the frequency domain configuration information of the first resource includes the bitmap information, the first communication device can determine the time domain position of the first resource based on the bitmap information.
[0249] For another example, in the case where the frequency domain configuration information of the first resource includes the starting time domain unit index of the first resource and / or the time domain unit quantity of the first resource, the first communication device can determine the frequency domain position of the first resource based on the starting time domain unit index of the first resource and / or the time domain unit quantity of the first resource.
[0250] As an example, the frequency domain configuration information of the first resource included in the first information includes any of the following:
[0251] a starting frequency domain unit index of the first resource; wherein the starting frequency domain unit index of the first resource is used to determine the frequency domain position of the first resource (for example, the quantity of frequency domain units occupied by the first resource is pre-configured or pre-defined); or,
[0252] a frequency domain unit quantity of the first resource; wherein the frequency domain unit quantity is used to determine the frequency domain position of the first resource (for example, the starting frequency domain unit position of the first resource is pre-configured or pre-defined, and / or the ending frequency domain unit position of the first resource is pre-configured or pre-defined); or,
[0253] a starting frequency domain unit index and a number of frequency domain units of the first resource (or a terminal frequency domain unit index and a number of frequency domain units of the first resource); wherein the starting frequency domain unit index and the number of frequency domain units of the first resource are used to determine the frequency domain location of the first resource.
[0254] For example, in a case that the frequency domain configuration information of the first resource comprises the starting frequency domain unit index of the first resource, the first communication apparatus can determine the frequency domain location of the first resource based on the starting frequency domain unit index of the first resource and the pre-configured (or pre-defined) number of frequency domain units.
[0255] For another example, in a case that the frequency domain configuration information of the first resource comprises the number of frequency domain units, the first communication apparatus can determine the frequency domain location of the first resource based on the number of frequency domain units and at least one of the starting frequency domain unit index of the first resource and the terminal frequency domain unit index of the first resource.
[0256] For another example, in a case that the frequency domain configuration information of the first resource comprises the starting frequency domain unit index and the number of frequency domain units of the first resource, the first communication apparatus can determine the frequency domain location of the first resource based on the starting frequency domain unit index and the number of frequency domain units of the first resource.
[0257] As an example, the configuration information of the resource pattern of the first resource contained in the first information comprises at least one of: subcarrier identification information of the resource pattern, symbol identification information of the resource pattern, identification information of the resource pattern, or code division multiplexing group number information.
[0258] Taking the case that the configuration information of the resource pattern of the first resource comprises the subcarrier identification information of the resource pattern as an example.
[0259] For example, the resource pattern of the first resource is the resource pattern shown in FIG. 4a or FIG. 4b, and correspondingly, the subcarrier identification information of the resource pattern can indicate that the subcarrier identification or index is 0, 4, 8.
[0260] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4c or FIG. 4d or FIG. 4e, and correspondingly, the subcarrier identification information of the resource pattern can indicate that the subcarrier identification or index is 1, 5, 6.
[0261] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4f, and correspondingly, the subcarrier identification information of the resource pattern can indicate that the subcarrier identification or index is 0, 1, 6, 7.
[0262] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4g, and correspondingly, the subcarrier identification information of the resource pattern can indicate that the subcarrier identification or index is 2, 3, 8, 9.
[0263] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4h, and correspondingly, the subcarrier identifier information of the resource pattern can indicate that the subcarrier identifiers or indexes are 4, 5, 10 and 11.
[0264] For example, the configuration information of the resource pattern of the first resource includes the symbol identifier information of the resource pattern.
[0265] For example, the resource pattern of the first resource is the resource pattern shown in FIG. 4b, and correspondingly, the symbol identifier information of the resource pattern can indicate that the symbol identifiers or indexes are 0 and 2.
[0266] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4d, and correspondingly, the symbol identifier information of the resource pattern can indicate that the symbol identifiers or indexes are 0 and 1.
[0267] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4e, and correspondingly, the subcarrier identifier information of the resource pattern can indicate that the subcarrier identifiers or indexes are 0, 1 and 2.
[0268] For example, the configuration information of the resource pattern of the first resource includes the identifier information of the resource pattern.
[0269] For example, the resource pattern of the first resource includes one of the resource patterns shown in FIGS. 4a to 4o, and correspondingly, the identifier information of the resource pattern can include the identifier information of the one of the resource patterns.
[0270] For example, the configuration information of the resource pattern of the first resource includes the code division multiplexing group number information.
[0271] For example, the resource pattern of the first resource is the resource pattern shown in FIG. 4f, and correspondingly, the code division multiplexing group number information can indicate that the code division multiplexing group number is 1.
[0272] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4i, and correspondingly, the code division multiplexing group number information can indicate that the code division multiplexing group number is 2.
[0273] For another example, the resource pattern of the first resource is the resource pattern shown in FIG. 4j, and correspondingly, the code division multiplexing group number information can indicate that the code division multiplexing group number is 3.
[0274] In addition, the configuration information of the resource pattern of the first resource can include at least one of the subcarrier identifier information of the resource pattern, the symbol identifier information of the resource pattern, the identifier information of the resource pattern or the code division multiplexing group number information, and specific implementation examples of each item of information can refer to the above description.
[0275] In a possible implementation, the first information received by the first communication device in step S301 comprises first indication information, which is used to indicate a sequence parameter used to determine a sequence carried by the first resource. Specifically, the first information received by the first communication device can further comprise first indication information used to indicate a sequence parameter, so that the first communication device can determine the sequence carried by the first resource for interference measurement based on the sequence parameter, and facilitate signal processing (e.g., reception of the signal, processing of the signal, etc.) of the signal generated by the first communication device on the sequence.
[0276] For example, the sequence parameter can comprise at least one of the following: scrambling identity, cell identity, beam identity, DMRS CDM group identity, radio network temporary identifier (RNTI) of the terminal, such as cell radio network temporary identifier (C-RNTI), etc.
[0277] Optionally, the sequence carried by the first resource is used for measurement of the first resource (e.g., the sequence carried by the first resource is used for interference measurement of the first resource). Thus, the first communication device can determine the sequence carried by the first resource based on the sequence parameter indicated by the first indication information, and perform measurement on the first resource based on the sequence carried by the first resource, so as to improve the performance of interference measurement on the first resource.
[0278] Optionally, the first indication information can be carried in other messages / signaling / information other than the first information.
[0279] As described above, the resource pattern of the first resource can be implemented in various ways, and the configuration information included in the first information will be described below in combination with the above-mentioned various implementation manners.
[0280] In the first manner, the configuration information included in the first information satisfies one or more of the following implementation manners.
[0281] As an example, the first information can comprise configuration information of the resource pattern of the first resource.
[0282] As an example of the resource pattern configuration, the configuration information of the resource pattern of the first resource can configure the resource pattern of the first resource as the resource pattern of the PBCH DMRS.
[0283] As another example of the resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (e.g., the resource pattern of 3 REs shown in FIG. 4a).
[0284] As another example, the resource pattern of the first resource can be pre-defined by a protocol.
[0285] For example, the resource pattern of the first resource includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit.
[0286] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, which is used to indicate one of the one or more resource patterns.
[0287] For example, the resource pattern corresponding to the identification w1 of the resource pattern includes the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit. The configuration information of the resource pattern can indicate that the identification information of the resource pattern is w1.
[0288] As another example, the configuration information of the resource pattern of the first resource can indicate subcarrier identification information of the resource pattern.
[0289] The subcarrier identification information can be used to indicate subcarrier identification, or subcarrier index, or subcarrier position.
[0290] For example, the configuration information of the resource pattern of the first resource indicates the subcarrier index or subcarrier position (such as subcarriers 0, 4, and 8), and the subcarrier identification information can be indicated by a bit map. For example, 1 RB includes 12 subcarriers, a total of 12 bits, and one bit represents one subcarrier position, such as the bit map 100010001000. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.
[0291] As another example of resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a double-symbol resource pattern (such as the 6-RE pattern shown in FIG. 4b).
[0292] As another example, the resource pattern of the first resource can be protocol predefined.
[0293] For example, the resource pattern of the first resource includes partial positions on 2 symbols with an interval, such as the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit on the 0th symbol, and the 0th subcarrier (such as subcarrier 0), the 4th subcarrier (such as subcarrier 4), and the 8th subcarrier (such as subcarrier 8) in one frequency domain unit on the 2nd symbol.
[0294] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, the identification information being used to indicate one of the one or more resource patterns.
[0295] For example, the resource pattern corresponding to the identification w2 of the resource pattern includes partial positions on 2 symbols, such as the 0th subcarrier (e.g., subcarrier 0), the 4th subcarrier (e.g., subcarrier 4), and the 8th subcarrier (e.g., subcarrier 8) in one frequency domain unit on the 0th symbol; and the 0th subcarrier (e.g., subcarrier 0), the 4th subcarrier (e.g., subcarrier 4), and the 8th subcarrier (e.g., subcarrier 8) in one frequency domain unit on the 2nd symbol. The configuration information of the resource pattern can indicate that the identification information of the resource pattern is w2.
[0296] As an example of the frequency domain configuration, the frequency domain configuration information of the first resource includes a starting frequency domain unit index and / or a frequency domain unit quantity of the first resource.
[0297] Optionally, the starting frequency domain unit index can be at least one of a starting RB index, a starting RB position, a starting RBG index, or a starting RBG position.
[0298] Optionally, the frequency domain unit quantity can be a RB quantity or a RBG quantity.
[0299] For example, the frequency domain configuration information of the first resource can configure a starting RB position of the first resource, and a RB number (e.g., 4 RBs, 8 RBs, 10 RBs, 20 RBs, 40 RBs, etc.) occupied by the first resource can be preconfigured.
[0300] As another example of the frequency domain configuration, the frequency domain configuration information of the first resource can configure a starting RB position of the first resource, and a RB number (e.g., 4 RBs, 8 RBs, 10 RBs, 20 RBs, 40 RBs, etc.) occupied by the first resource.
[0301] As an example of the time domain configuration, the time domain configuration information of the first resource includes bitmap information used to indicate time domain resources included in the first resource.
[0302] Optionally, the bitmap information can be a bitmap of time domain units, such as a bitmap of symbols or a bitmap of symbol groups.
[0303] For example, the time domain configuration information of the first resource can include a bitmap of symbols occupied by the first resource.
[0304] For example, when a time slot includes 14 symbols, the time domain configuration information of the first resource can indicate a bitmap of 14 bits. Bit 1 represents a symbol position occupied by the first resource, and bit 0 represents a symbol position not occupied by the first resource (or, bit 0 represents a symbol position occupied by the first resource, and bit 1 represents a symbol position not occupied by the first resource).
[0305] For example, when the bitmap has a value of 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, symbols 2, 5, and 6 are symbol positions occupied by the first resource.
[0306] For example, when the bitmap has a value of 0, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, symbols 2, 5, and 7 are symbol positions occupied by the first resource.
[0307] As another example of time domain configuration, the time domain configuration information of the first resource includes a starting time domain unit index of the first resource and / or a number of time domain units of the first resource.
[0308] Optionally, the starting time domain unit index can be a starting symbol index, a starting symbol position, a starting symbol group index, or a starting symbol group position.
[0309] Optionally, the number of time domain units can be a number of symbols or a number of symbol groups.
[0310] For example, the time domain configuration information of the first resource can indicate a starting symbol position of the first resource.
[0311] For example, the time domain configuration information of the first resource can indicate a symbol index of a starting symbol, and a corresponding symbol position is determined according to a resource pattern of the first resource.
[0312] For example, when the resource pattern of the first resource is a single-symbol resource pattern, the symbol indicated by the symbol index included in the time domain configuration information of the first resource is a symbol occupied by the first resource.
[0313] For example, when the symbol index is s1, symbol s1 is a symbol occupied by the first resource.
[0314] For example, when the resource pattern of the first resource is a double-symbol resource pattern, the symbol indicated by the symbol index included in the time domain configuration information of the first resource and the symbol indicated by symbol index+2 are symbols occupied by the first resource.
[0315] For example, when the symbol index is s1, symbols s1 and s1+2 are symbols occupied by the first resource.
[0316] For example, the number of time domain units can be predefined. For example, the predefined number of symbols is 1, or 2. The corresponding symbol position is determined based on the starting symbol position and the number of symbols.
[0317] For example, when the number of symbols is 1, the time domain configuration information of the first resource contains the symbol of the symbol index. The symbol is occupied by the first resource.
[0318] For example, the symbol index is s1, and the symbol s1 is occupied by the first resource.
[0319] For example, when the number of symbols is 2, the time domain configuration information of the first resource contains the symbol of the symbol index and the symbol of symbol index+2. The symbols are occupied by the first resource.
[0320] For example, the symbol index is s1, and the symbols s1 and s1+2 are occupied by the first resource.
[0321] As an example of the first indication information, the first indication information can indicate the cell identity and / or SSB identity. Correspondingly, the first communication device can determine the sequence on the first resource according to the cell identity and / or SSB identity, and then perform channel estimation and PMI reporting according to the sequence.
[0322] In the second way, the configuration information contained in the first information satisfies one or more of the following implementation manners.
[0323] As an example, the first information can contain configuration information of the resource pattern of the first resource.
[0324] As an example of resource pattern configuration, the configuration information of the resource pattern of the first resource can configure the resource pattern of the first resource as the resource pattern of the PDCCH DMRS.
[0325] As another example of resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (for example, the resource pattern of 3 REs shown in FIG. 4c).
[0326] As another example, the resource pattern of the first resource can be predefined by the protocol.
[0327] For example, the resource pattern of the first resource includes the 1st subcarrier (such as subcarrier 1), the 5th subcarrier (such as subcarrier 5), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit.
[0328] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, which is used to indicate one of the one or more resource patterns.
[0329] For example, the resource pattern corresponding to the identification w3 of the resource pattern includes the 1st subcarrier (such as subcarrier 1), the 5th subcarrier (such as subcarrier 5), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit. The configuration information of the resource pattern can indicate that the identification information of the resource pattern is w3.
[0330] As another example, the configuration information of the resource pattern of the first resource can indicate subcarrier identification information of the resource pattern.
[0331] The subcarrier identification information can be used to indicate subcarrier identification, or subcarrier index, or subcarrier position.
[0332] For example, the configuration information of the resource pattern of the first resource indicates the subcarrier index or subcarrier position (such as subcarriers 1, 5, and 9), and the subcarrier identification information can be indicated by a bit map. For example, 1 RB includes 12 subcarriers, and a total of 12 bits, one bit representing one subcarrier position, such as the bit map 010001000100. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.
[0333] As another example of resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a double-symbol resource pattern (such as the 6-RE pattern shown in FIG. 4d).
[0334] As another example, the resource pattern of the first resource can be protocol predefined.
[0335] For example, the resource pattern of the first resource includes partial positions on two consecutive symbols, such as the 1st subcarrier (such as subcarrier 1), the 5th subcarrier (such as subcarrier 5), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit on the 0th symbol; and the 1st subcarrier (such as subcarrier 1), the 5th subcarrier (such as subcarrier 5), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit on the 1st symbol.
[0336] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, which is used to indicate one of the one or more resource patterns.
[0337] For example, the resource pattern corresponding to the identification w4 of the resource pattern includes partial positions on 2 consecutive symbols, such as the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 0th symbol; and the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 1st symbol. The configuration information of the resource pattern can indicate that the identification information of the resource pattern is w4.
[0338] As another example of the resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a three-symbol resource pattern (e.g., the 9-RE pattern shown in FIG. 4e).
[0339] As another example, the resource pattern of the first resource can be protocol predefined.
[0340] For example, the resource pattern of the first resource includes partial positions on 3 consecutive symbols, such as the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 0th symbol; the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 1st symbol; and the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 2nd symbol.
[0341] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, which is used to indicate one of the one or more resource patterns.
[0342] For example, the resource pattern corresponding to the identification w5 of the resource pattern includes partial positions on 3 consecutive symbols, such as the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 0th symbol; the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 1st symbol; and the 1st subcarrier (e.g., subcarrier 1), the 5th subcarrier (e.g., subcarrier 5), the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 2nd symbol. The configuration information of the resource pattern can indicate that the identification information of the resource pattern is w5.
[0343] As an example of the frequency domain configuration, the frequency domain configuration information of the first resource includes a starting frequency domain unit index and / or a frequency domain unit quantity of the first resource.
[0344] Optionally, the starting frequency domain unit index can be at least one of a starting RB index, a starting RB position, a starting RBG index, or a starting RBG position.
[0345] Optionally, the frequency domain unit quantity can be a RB quantity or a RBG quantity.
[0346] For example, the frequency domain configuration information of the first resource can configure a starting RB position of the first resource, and a RB quantity (e.g., 4 RBs, 8 RBs, 10 RBs, 20 RBs, 40 RBs, etc.) occupied by the first resource can be preconfigured.
[0347] As another example of the frequency domain configuration, the time domain configuration information of the first resource includes bitmap information used to indicate time domain resources included in the first resource.
[0348] Optionally, the bitmap information can be a bitmap of time domain units, such as a bitmap of symbols or a bitmap of symbol groups.
[0349] For example, the frequency domain configuration information of the first resource can configure a starting RB position of the first resource, and a RB quantity (e.g., 4 RBs, 8 RBs, 10 RBs, 20 RBs, 40 RBs, etc.) occupied by the first resource.
[0350] As an example of the time domain configuration, the time domain configuration information of the first resource can include a bitmap of symbols occupied by the first resource. For example, when a time slot includes 14 symbols, the time domain configuration information of the first resource can indicate a 14-bit bitmap. Bit 1 represents a symbol position occupied by the first resource, and bit 0 represents a symbol position not occupied by the first resource (or, bit 0 represents a symbol position occupied by the first resource, and bit 1 represents a symbol position not occupied by the first resource).
[0351] For example, when the bitmap has values 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, symbol 2, symbol 5, and symbol 6 are symbol positions occupied by the first resource.
[0352] For another example, when the bitmap has values 0, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, symbol 2, symbol 5, and symbol 7 are symbol positions occupied by the first resource.
[0353] As another example of time domain configuration, the time domain configuration information of the first resource includes a starting time domain unit index of the first resource and / or a time domain unit quantity of the first resource.
[0354] Optionally, the starting time domain unit index can be a starting symbol index, a starting symbol position, a starting symbol group index, or a starting symbol group position.
[0355] Optionally, the time domain unit quantity can be a symbol quantity, or a symbol group quantity.
[0356] For example, the time domain configuration information of the first resource can indicate a starting symbol position of the first resource.
[0357] For example, the time domain configuration information of the first resource can indicate a symbol index of the starting symbol, and the corresponding symbol position is determined based on the resource pattern of the first resource.
[0358] For example, when the resource pattern of the first resource is a single-symbol resource pattern, the symbol indicated by the symbol index contained in the time domain configuration information of the first resource is the symbol occupied by the first resource.
[0359] For example, when the symbol index is s1, the symbol s1 is the symbol occupied by the first resource.
[0360] For example, when the resource pattern of the first resource is a double-symbol resource pattern, the symbol indicated by the symbol index contained in the time domain configuration information of the first resource and the symbol indicated by symbol index+1 are the symbols occupied by the first resource.
[0361] For example, when the symbol index is s1, the symbol s1 and the symbol s1+1 are the symbols occupied by the first resource.
[0362] For example, when the resource pattern of the first resource is a triple-symbol resource pattern, the symbol indicated by the symbol index contained in the time domain configuration information of the first resource, the symbol indicated by symbol index+1, and the symbol indicated by symbol index+2 are the symbols occupied by the first resource.
[0363] For example, when the symbol index is s1, the symbol s1, the symbol s1+1, and the symbol s1+2 are the symbols occupied by the first resource.
[0364] For example, in the case of one symbol, the symbol in the symbol index contained in the time domain configuration information of the first resource is the symbol occupied by the first resource. For example, the symbol index is s1, and the symbol s1 is the symbol occupied by the first resource.
[0365] For example, in the case of two symbols, the symbol in the symbol index and the symbol in the symbol index+1 contained in the time domain configuration information of the first resource are the symbols occupied by the first resource. For example, the symbol index is s1, and the symbol s1 and the symbol s1+1 are the symbols occupied by the first resource.
[0366] For example, in the case of three symbols, the symbol in the symbol index, the symbol in the symbol index+1, and the symbol in the symbol index+2 contained in the time domain configuration information of the first resource are the symbols occupied by the first resource. For example, the symbol index is s1, and the symbol s1, the symbol s1+1, and the symbol s1+2 are the symbols occupied by the first resource.
[0367] As an example of the first indication information, the first indication information can indicate a scrambling identity (for example, a scrambling identity of a PDCCH), and accordingly, the first communication device can determine a sequence on the first resource according to the scrambling identity, and then perform channel estimation and PMI reporting of interference according to the sequence.
[0368] In the third mode, the configuration information contained in the first information satisfies one or more of the following implementation modes.
[0369] As an example of resource pattern configuration, the configuration information of the resource pattern of the first resource can configure the resource pattern of the first resource as the resource pattern of the PDSCH DMRS.
[0370] As another example of resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (for example, the resource pattern of 4 REs shown in FIG. 4f).
[0371] As another example, the resource pattern of the first resource can be protocol predefined.
[0372] For example, the resource pattern of the first resource includes the 0th subcarrier (such as subcarrier 0), the 1st subcarrier (such as subcarrier 1), the 6th subcarrier (such as subcarrier 6), and the 7th subcarrier (such as subcarrier 7) in one frequency domain unit.
[0373] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, and the identification information is used to indicate one of one or more resource patterns.
[0374] For example, the resource pattern corresponding to the identifier w6 of the resource pattern includes the 0th subcarrier (such as subcarrier 0), the 1st subcarrier (such as subcarrier 1), the 6th subcarrier (such as subcarrier 6), and the 7th subcarrier (such as subcarrier 7) in a frequency domain unit. The configuration information of the resource pattern can indicate that the identifier information of the resource pattern is w6.
[0375] As another example, the configuration information of the resource pattern of the first resource can indicate the subcarrier identifier information of the resource pattern.
[0376] The subcarrier identifier information can be used to indicate a subcarrier identifier, or a subcarrier index, or a subcarrier position.
[0377] For example, the configuration information of the resource pattern of the first resource indicates the subcarrier index or the subcarrier position (such as subcarriers 0, 1, 6, and 7), and the subcarrier identifier information can be indicated by a bit map. For example, 1 RB includes 12 subcarriers, a total of 12 bits, and one bit represents one subcarrier position, such as a bit map of 110000110000. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.
[0378] As another example of resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (such as the 4-RE pattern shown in FIG. 4g, FIG. 4h, FIG. 4i, or FIG. 4j). The resource pattern of the first resource can be protocol predefined, the configuration information of the resource pattern of the first resource can indicate the identifier information of the resource pattern, or the configuration information of the resource pattern of the first resource can indicate the subcarrier identifier information of the resource pattern. For details, refer to the implementation examples of the 4-RE resource pattern shown in FIG. 4f.
[0379] For example, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (such as the 4-RE pattern shown in FIG. 4g).
[0380] For example, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (such as the 4-RE pattern shown in FIG. 4h).
[0381] For example, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a single-symbol resource pattern (such as the 8-RE pattern shown in FIG. 4i).
[0382] For another example, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a resource pattern of two symbols (e.g., the resource pattern of 8 REs shown in FIG. 4k).
[0383] For another example, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a resource pattern of two symbols (e.g., the resource pattern of 8 REs shown in FIG. 4k).
[0384] As another example, the resource pattern of the first resource can be protocol predefined.
[0385] For example, the resource pattern of the first resource includes partial positions on two consecutive symbols, such as the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on the 0th symbol; and the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on the 1st symbol.
[0386] As another example, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, which is used to indicate one of the one or more resource patterns.
[0387] For example, the resource pattern corresponding to the identification w7 of the resource pattern includes partial positions on two consecutive symbols, such as the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on the 0th symbol; and the 0th subcarrier (e.g., subcarrier 0), the 1st subcarrier (e.g., subcarrier 1), the 6th subcarrier (e.g., subcarrier 6), and the 7th subcarrier (e.g., subcarrier 7) in one frequency domain unit on the 1st symbol. The configuration information of the resource pattern can indicate that the identification information of the resource pattern is w7.
[0388] As another example, the configuration information of the resource pattern of the first resource can indicate subcarrier identification information of the resource pattern.
[0389] The subcarrier identification information can be used to indicate a subcarrier identification, or a subcarrier index, or a subcarrier position.
[0390] For example, the configuration information of the resource pattern of the first resource indicates subcarrier indices or subcarrier positions (such as subcarriers 0, 1, 6, 7), and the subcarrier identification information can be indicated by a bitmap. For example, 1 RB includes 12 subcarriers, a total of 12 bits, and one bit represents one subcarrier position, such as a bitmap of 110000110000. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.
[0391] As another example of resource pattern configuration, the configuration information of the resource pattern of the first resource can indicate that the resource pattern of the first resource is a two-symbol resource pattern (such as the 8-RE pattern shown in FIG. 4l, FIG. 4m, FIG. 4n, or FIG. 4o). Wherein, the resource pattern of the first resource can be protocol predefined, the configuration information of the resource pattern of the first resource can indicate identification information of the resource pattern, or the configuration information of the resource pattern of the first resource can indicate subcarrier identification information of the resource pattern; For specific implementation examples, refer to the 8-RE resource pattern shown in FIG. 4k.

[0411] As shown in the example of FIG. 4o, the RBs on each of the one or more symbols collectively have 12 subcarriers, which are indexed as subcarriers 0, 1, 2,... 11.

In other words, the first resource can include 24 REs in FIG. 4o.
[0412] As an example of the frequency domain configuration, the frequency domain configuration information of the first resource includes a starting frequency domain unit index and / or a frequency domain unit quantity of the first resource.
[0413] Optionally, the starting frequency domain unit index can be at least one of a starting RB index, a starting RB position, a starting RBG index, or a starting RBG position.
[0414] Optionally, the frequency domain unit quantity can be a RB quantity or a RBG quantity.
[0415] For example, the frequency domain configuration information of the first resource can configure a starting RB position of the first resource, and a RB quantity (e.g., 4 RBs, 8 RBs, 10 RBs, 20 RBs, 40 RBs, etc.) occupied by the first resource can be preconfigured.
[0416] As another example of the frequency domain configuration, the time domain configuration information of the first resource includes bitmap information used to indicate time domain resources included in the first resource.
[0417] Optionally, the bitmap information can be a bitmap of time domain units, such as a bitmap of symbols or a bitmap of symbol groups.
[0418] For example, the frequency domain configuration information of the first resource can configure a starting RB position of the first resource, and a RB quantity (e.g., 4 RBs, 8 RBs, 10 RBs, 20 RBs, 40 RBs, etc.) occupied by the first resource.
[0419] As an example of the time domain configuration, the time domain configuration information of the first resource can include a bitmap of symbols occupied by the first resource. For example, when a time slot includes 14 symbols, the time domain configuration information of the first resource can indicate a 14-bit bitmap. Bit 1 represents a symbol position occupied by the first resource, and bit 0 represents a symbol position not occupied by the first resource (or, bit 0 represents a symbol position occupied by the first resource, and bit 1 represents a symbol position not occupied by the first resource).
[0420] For example, when the bitmap has values 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, symbol 2, symbol 5, and symbol 6 are symbol positions occupied by the first resource.
[0421] For another example, when the bitmap has values 0, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, symbol 2, symbol 5, and symbol 7 are symbol positions occupied by the first resource.
[0422] As another example of time domain configuration, the time domain configuration information of the first resource includes a starting time domain unit index of the first resource and / or a time domain unit quantity of the first resource.
[0423] Optionally, the starting time domain unit index can be a starting symbol index, a starting symbol position, a starting symbol group index, or a starting symbol group position.
[0424] Optionally, the time domain unit quantity can be a symbol quantity, or a symbol group quantity.
[0425] For example, the time domain configuration information of the first resource can indicate a starting symbol position of the first resource. Illustratively, the time domain configuration information of the first resource can indicate a symbol index of the starting symbol, and the corresponding symbol position is determined based on the resource pattern of the first resource.
[0426] For example, in the case that the resource pattern of the first resource is a single-symbol resource pattern, the symbol of the symbol index contained in the time domain configuration information of the first resource is the symbol occupied by the first resource.
[0427] For example, if the symbol index is s1, then the symbol s1 is the symbol occupied by the first resource.
[0428] For example, in the case that the resource pattern of the first resource is a double-symbol resource pattern, the symbol of the symbol index contained in the time domain configuration information of the first resource and the symbol of symbol index+1 are the symbols occupied by the first resource.
[0429] For example, if the symbol index is s1, then the symbol s1 and the symbol s1+1 are the symbols occupied by the first resource.
[0430] For example, in the case that the resource pattern of the first resource is a triple-symbol resource pattern, the symbol of the symbol index contained in the time domain configuration information of the first resource, the symbol of symbol index+1 and the symbol of symbol index+2 are the symbols occupied by the first resource.
[0431] For example, if the symbol index is s1, then the symbol s1, the symbol s1+1 and the symbol s1+2 are the symbols occupied by the first resource.
[0432] Illustratively, the time domain unit quantity can be predefined. For example, the predefined symbol quantity is 1, or 2, or 3. The corresponding symbol position is determined based on the starting symbol position and the symbol quantity.
[0433] For example, in the case of one symbol, the symbol indicated by the symbol index included in the time domain configuration information of the first resource is the symbol occupied by the first resource. For example, the symbol index is s1, and the symbol s1 is the symbol occupied by the first resource.
[0434] For example, in the case of two symbols, the symbols indicated by the symbol index and the symbol index+1 included in the time domain configuration information of the first resource are the symbols occupied by the first resource. For example, the symbol index is s1, and the symbols s1 and s1+1 are the symbols occupied by the first resource.
[0435] For example, in the case of three symbols, the symbols indicated by the symbol index, the symbol index+1 and the symbol index+2 included in the time domain configuration information of the first resource are the symbols occupied by the first resource. For example, the symbol index is s1, and the symbols s1, s1+1 and s1+2 are the symbols occupied by the first resource.
[0436] As an example of the first indication information, the first indication information can indicate a scrambling identity (e.g., a scrambling identity of a PDCCH), and accordingly, the first communication device can determine a sequence on the first resource according to the scrambling identity, and then perform channel estimation and PMI reporting according to the sequence.
[0437] It should be noted that the above examples are described by one of the ways in which the first resource is implemented. As described above, the first resource can be implemented by at least one of the first way, the second way or the third way. In other words, the first resource can be implemented by two or three of the first way, the second way or the third way, i.e., the resource configuration information of the first resource can include two or three of the resource configuration information corresponding to the first way, the resource configuration information corresponding to the second way, or the resource configuration information corresponding to the third way. The resource configuration information can include at least one of the resource pattern configuration information, the time domain configuration information, and the frequency domain configuration information. In the following, the resource configuration information including the resource pattern configuration information will be described as an example.
[0438] As an example, the resource configuration information of the first resource can include the resource pattern configuration information corresponding to the first way and the resource pattern configuration information corresponding to the second way. For example, the resource pattern configuration information corresponding to the first way can indicate the resource pattern shown in FIG. 4a or FIG. 4b, and the resource pattern configuration information corresponding to the second way can indicate the resource pattern shown in FIG. 4c or FIG. 4d or FIG. 4e.
[0439] As another example, the resource configuration information of the first resource can comprise the resource pattern configuration information corresponding to the first mode, and the resource pattern configuration information corresponding to the third mode. For example, the resource pattern configuration information corresponding to the first mode can indicate the resource pattern shown in FIG. 4a or FIG. 4b, and the resource pattern configuration information corresponding to the third mode can indicate the resource pattern shown in any one of FIG. 4f to FIG. 40.
[0440] As another example, the resource configuration information of the first resource can comprise the resource pattern configuration information corresponding to the first mode, the resource pattern configuration information corresponding to the second mode, and the resource pattern configuration information corresponding to the third mode. For example, the resource pattern configuration information corresponding to the first mode can indicate the resource pattern shown in FIG. 4a or FIG. 4b, the resource pattern configuration information corresponding to the second mode can indicate the resource pattern shown in FIG. 4c or FIG. 4d or FIG. 4e, and the resource pattern configuration information corresponding to the third mode can indicate the resource pattern shown in any one of FIG. 4f to FIG. 40.
[0441] In a possible implementation, the method shown in FIG. 3 further comprises: the first communication device sending second information, the second information being used to indicate the interference measurement result information corresponding to the first resource. Specifically, after obtaining the interference measurement result information based on the first resource in step S302, the first communication device can further send the second information indicating the interference measurement result information, so that the receiver (for example, the second communication device) of the second information can determine the interference measurement result corresponding to the first resource, so as to facilitate the receiver to perform resource management based on the interference measurement result.
[0442] Optionally, the above-mentioned resource management can comprise one or more of radio resource management (RRM), data transmission, etc. For example, the RRM comprises one or more of cell selection and reselection, power control, access control, handover management, load control, frequency allocation (for example, carrier aggregation (CA) related configuration, including but not limited to activating and deactivating carrier aggregation, configuring aggregated carrier set, allocating resource block, etc.), channel allocation, interference management.
[0443] For example, the data transmission can comprise one or more of determining resource of data transmission, precoding, antenna port, number of layers, modulation and coding scheme, code rate, multi-user multiplexing strategy.
[0444] Optionally, the first communication device can perform interference measurement by using existing interference measurement method, such as performing interference power averaging, or interference power normalization, etc. The first communication device can also use other interference measurement methods, such as performing mathematical operation on the received interference power to obtain interference power, for example, the mathematical operation can be linear operation or nonlinear operation, etc. The first communication device can also use other interference measurement methods, which are not limited in the present application.
[0445] Optionally, the first communication device can not send the second information. For example, the first communication device can explicitly indicate that the interference is low by means of muting in the case that the interference measurement information indicates that the interference is lower than or equal to a threshold, so as to reduce the transmission overhead.
[0446] In a possible implementation, the interference measurement information satisfies at least one of the following conditions:
[0447] The interference measurement information comprises interference measurement information corresponding to at least one of the N frequency domain resources included in the first resource, and N is a positive integer.
[0448] The interference measurement information comprises interference measurement information corresponding to at least one of the P time domain resources included in the first resource, and P is a positive integer.
[0449] The interference measurement information comprises signal quality information corresponding to a signal carried by the first resource; or
[0450] The interference measurement information comprises channel state information (CSI) corresponding to a signal carried by the first resource.
[0451] Therefore, the interference measurement information indicated by the second information can be implemented by at least one of the above conditions, so as to improve the flexibility of the implementation scheme.
[0452] For example, when the first resource comprises N frequency domain resources, the first communication device can feed back channel state information for the N frequency domain resources respectively. For another example, when the first resource comprises P time domain resources, the first communication device can feed back channel state information for each time domain resource respectively. For another example, when the first resource comprises a plurality of symbol groups, the first communication device can feed back channel state information for each symbol group respectively. For another example, when the first resource comprises a plurality of REs, the first communication device can feed back channel state information for each RE respectively. For another example, when the first resource comprises a plurality of RE groups, the first communication device can feed back channel state information for each RE group respectively.
[0453] For example, when the first resource comprises N frequency domain resources, the first communication device can feed back channel state information for at least one frequency domain resource. For another example, when the first resource comprises P time domain resources, the first communication device can feed back channel state information for at least one time domain resource respectively. For another example, when the first resource comprises a plurality of symbols, the first communication device can feed back channel state information for at least one symbol. For another example, when the first resource comprises a plurality of symbol groups, the first communication device can feed back channel state information for at least one symbol group. For another example, when the first resource comprises a plurality of REs, the first communication device can feed back channel state information for at least one RE. For another example, when the first resource comprises a plurality of RE groups, the first communication device can feed back channel state information for at least one RE group.
[0454] Optionally, the signal quality information can comprise one or more of a reference signal received power (RSRP), an interference measurement reference signal received power (IM-RSRP), a signal to interference plus noise ratio (SINR), a signal to noise ratio (SNR).
[0455] Optionally, the CSI can comprise one or more of channel quality information (CQI), RSRP, reference signal received quality (RSRQ), received signal strength indication (RSSI), precoding matrix indication (PMI), rank indication (RI), or layer indication (LI).
[0456] Optionally, the interference measurement result information can comprise power related information, such as RSRP, IM-RSRP, etc. Taking IM-RSRP as an example, the power corresponding to the IM-RSRP can comprise at least one of: total interference power of the interference measurement resource, average interference power of the interference measurement resource, interference power corresponding to a certain frequency range, interference power corresponding to a certain symbol, interference power corresponding to a certain RE group, or interference power corresponding to a certain RE.
[0457] Optionally, the interference measurement result information comprises at least one of: an index of the first resource, an index of a signal carried by the first resource, an index of a signal corresponding to the interference measurement result, an index of a resource corresponding to the interference measurement result, an index of a frequency domain resource corresponding to the interference measurement result, or an index of a time domain unit corresponding to the interference measurement result. Specifically, the interference measurement result information can comprise the at least one index, so that the receiver of the second information can determine the measurement object (i.e. resource and / or signal) corresponding to the interference measurement result information based on the at least one index, to obtain the interference situation corresponding to the measurement object.
[0458] In the above process, the CQI can be selected by the receiving end based on the measured signal-to-noise ratio (SNR) or signal-to-interference-and-noise ratio (SINR). For example, the value of the CQI can be selected from a predefined table that maps SINR / SNR values to the index of the CQI. This mapping is based on the assumption that a higher SINR / SNR value indicates better channel conditions, allowing a higher data rate to be used. The CQI can be selected based on the current channel conditions and the target block error rate (BLER) using a predefined mapping table.
[0459] Optionally, SINR is a key indicator of signal quality, especially in wireless communication systems. For example, SINR satisfies:
[0460] where P s is the power of the received signal, P i is the power of the interference signal, and P n is the noise power at the receiving end.
[0461] As an example, the above interference measurement result information can include RSRP, where the RSRP of the interference measurement resource can be referred to as the RSRP of the interference measurement, i.e., IM-RSRP. Optionally, the IM-RSRP reporting can be periodic reporting, semi-persistent reporting, or aperiodic reporting.
[0462] For example, the second communication device can configure a CSI-IM resource for the first communication device, and the IM-RSRP can be reported for the CSI-IM resource. The second communication device can configure reporting parameters in the reporting configuration of the CSI-IM resource, and the reporting parameters include the IM-RSRP.
[0463] For another example, the second communication device can configure a CSI-RS resource for the first communication device, and the IM-RSRP can be reported for the CSI-RS resource. The second communication device can configure reporting parameters in the reporting configuration of the CSI-RS resource, and the reporting parameters include the IM-RSRP.
[0464] As another example, the above interference measurement result information can include CQI or SINR.
[0465] The CQI can be used to reflect the interference situation. For example, the calculation formula of the above SINR includes interference information.
[0466] Optionally, the CSI-IM resource is included in the configuration of the related measurement resource for CQI reporting.
[0467] Optionally, the CQI included in the interference measurement result information can be the value after SINR quantization.
[0468] In a possible implementation, before the first communication device sends the second information, the second communication device can indicate to the first communication device whether to report the interference measurement result. For example, the second communication device indicates whether to report the measurement result in the reporting configuration.
[0469] As an example, taking the CSI-IM resource as an example. The second communication device can configure one or more CSI-IM resources for the first communication device. Correspondingly, when the first communication device reports the channel state information through the second information, the first communication device can report the identifier (for example, CSI-IM resource ID) of the CSI-IM resource and the corresponding IM-RSRP.
[0470] Optionally, the second communication device can configure the number of reported measurement results (for example, IM-RSRP) for the first communication device, and / or indicate the threshold of the reported interference measurement result.
[0471] For example, the first communication device can preferentially report the CSI-IM resource ID and the corresponding interference measurement result (for example, IM-RSRP) with a smaller value according to the number of reported interference measurement results (for example, IM-RSRP). Compared with reporting the interference measurement result (for example, IM-RSRP) of each CSI-IM resource, this method can reduce the reporting overhead.
[0472] For another example, the first communication device can determine the interference measurement result (for example, IM-RSRP) corresponding to the interference measurement resource (for example, CSI-IM resource) greater than the threshold according to the reporting threshold. For example, the first communication device reports the bitmap corresponding to the CSI-IM resource ID, 1 represents greater than the threshold, and 0 represents less than the threshold. The IM-RSRP of the CSI-IM resource greater than the threshold can be further fed back. Compared with reporting the IM-RSRP of each CSI-IM resource, this method can reduce the reporting overhead.
[0473] Optionally, when the first communication device performs the interference measurement result (for example, IM-RSRP) reporting, the quantization reporting of the interference measurement result can be considered.
