Description

Processing method, communication device and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a processing method, communication equipment and storage medium. Background Art

[0002] With the development of 5G technology, to reduce costs and meet more refined requirements, and considering the balance between cost and performance, reduced capability (Redcap) terminals have been proposed. These are mainly suitable for scenarios with bandwidth, power consumption, cost, and other requirements between enhanced mobile broadband (eMBB) and low-power wide-area (LPWA) networks. Discussions on Redcap technology have shown that reducing or limiting the UE bandwidth to, for example, 10M / 5MHz will bring some backward compatibility issues. For example, most control resource set (CORESET) #0 configurations in FR1 may not be supported.

[0003] On the one hand, under the reduced bandwidth, the maximum aggregation level supported by CORESET#0 is 4, so insufficient coverage may occur in some scenarios. Therefore, the number of resources occupied by CORESET#0 needs to be increased to ensure coverage at the cell edge. On the other hand, when the subcarrier spacing of CORESET#0 is 30KHz, according to the existing protocol, the number of resource blocks (RBs) it occupies is at least 24, but the maximum number of RBs under 5MHz bandwidth is 11, so the current bandwidth cannot meet the initial access bandwidth requirements of CORESET#0. Therefore, it is also necessary to improve the design of the multiplexing mode of CORESET#0, synchronization signal / physical broadcast channel (PBCH) block (SSB) and CORESET#0.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art.

[0067] The purpose of this application, its features, and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings. The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and the accompanying text are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of this application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0068] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0069] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0070] It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if" as used herein may be interpreted as "when," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the described features, steps, operations, elements, components, items, types, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0071] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0072] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0073] It should be noted that in this article, step codes such as S301 and S302 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial restriction on the order. When implementing the step, those skilled in the art may execute S302 first and then S301, etc., but these should all be within the scope of protection of this application.

[0074] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0075] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0076] The communication device in this application can be a terminal device (such as a mobile phone) or a network device (such as a base station). The specific reference needs to be clarified in the context.

They also include low-power, low-complexity, low-cost, and low-performance smartphones. Standard devices include smartphones and smart cars. The difference between lightweight and standard devices is not limited to device type. For example, standard devices in low-power or low-performance states can also be considered lightweight devices. The main difference lies in the device's current bandwidth, data rate, and other factors.

[0079] The subsequent description will be made by taking a mobile terminal as an example. It will be understood by those skilled in the art that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminals.

Those skilled in the art will appreciate that the mobile terminal structure shown in FIG1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0081] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0082] The RF unit 101 can be used to receive and transmit signals during information transmission or calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. Optionally, it can send uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication.

[0083] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0084] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0085] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0086] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072.

When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0090] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100.

[0091] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0092] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0093] The mobile terminal 100 may further include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby managing charging, discharging, and power consumption through the power management system.

[0094] Although not shown in FIG. 1 , the mobile terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0095] To facilitate understanding of the embodiments of the present application, the communication network system on which the mobile terminal of the present application is based is described below.

[0101] Although the above introduction is made using the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but can also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems (such as 5G), etc., which are not limited here.

[0102] Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0103] To facilitate understanding of the processing method provided in the embodiments of the present application, the control resource set (CORESET) is introduced below:

[0104] In 5G NR, a CORESET is a set of physical resources within a specific area of ​​the downlink resource grid, used to carry downlink control information (DCI) in the physical downlink control channel (PDCCH). Among various CORESETs, CORESET#0 is used for scheduling System Information Block 1 (SIB1) and is involved from the beginning during the initial cell search process. As mentioned above, the reduced / limited bandwidth affects the number of resources occupied by CORESET#0, for example, the number of resources is lower than the required level, which is likely to cause insufficient initial access bandwidth and / or insufficient coverage. Therefore, at least the above-mentioned problems can be solved by improving the configuration / indication of resource allocation for CORESET#0.

[0105] Based on the above explanation, in order to effectively increase the number of resources occupied by the control resource set under limited bandwidth conditions, thereby improving insufficient initial access bandwidth and / or insufficient coverage, the present application provides a processing method, communication device, and storage medium. The processing method, communication device, and storage medium provided in the embodiments of the present application are further described in detail below.

[0106] FIG3 is a flow chart of an information processing method provided by an embodiment of the present application. As shown in FIG3 , the information processing method includes at least the following steps S301 to S304. The method execution subject shown in FIG3 can be a terminal device (for example, the mobile terminal 100 of FIG1 or the UE 201 of FIG2 ). Alternatively, the method execution subject shown in FIG3 can be a chip in the terminal device. FIG3 is illustrated by taking the terminal device as the execution subject of the method as an example.

[0107] S301: Receive first indication information, where the first indication information meets a preset condition.

[0108] In an embodiment of the present application, the first indication information may be received by the terminal device from the network device, and the first indication information may be a main information block (MIB). As a MIB, the first indication information can be obtained on the PBCH channel, and may at least include the configuration corresponding field pdcch-ConfigSIB1 of CORESET#0, the configuration corresponding field dmrs-typeA-position of the first demodulation reference signal, etc. The high 4-bit index (index) of the pdcch-ConfigSIB1 field of the MIB indicates CORESRT#0, including the number of RBs in the frequency domain and the number of symbols in the time domain it occupies. The dmrs-typeA-position field of the MIB indicates the symbol position of the demodulation reference signal (DMRS) of the corresponding physical downlink shared channel (PDSCH), and its specific indication method will be described in detail below.

[0109] In an embodiment of the present application, the first indication information indicates resource information of a control resource set corresponding to a physical downlink control channel, and / or a frequency domain offset between a synchronization signal block and a control resource set, for example, indicated by the pdcch-ConfigSIB1 field of the MIB. Optionally, the first indication information further indicates an index of a starting symbol of a first demodulation reference signal, for example, indicated by the dmrs-typeA-position field of the MIB.

[0110] In an embodiment of the present application, the first indication information meeting the preset condition may mean that the information / parameter indicated by the first indication information meets the preset condition. More details about the preset condition will be described in detail below.

[0111] S302: Receive a physical downlink control channel according to the first indication information.

[0112] In an embodiment of the present application, after receiving the first indication information, the terminal device may decode further information from the first indication information, for example, obtain the pdcch-ConfigSIB1 field, etc. Then, the terminal device may receive the PDCCH based on the further information decoded from the first indication information.

[0113] In a possible implementation, the terminal device can obtain the pdcch-ConfigSIB1 field from the first indication information of the MIB, and obtain resource information about CORESRT#0 through the field (for example, the index of its upper 4 bits) according to a predetermined rule (for example, an existing communication protocol or an improved solution of the present application), as shown in Table 1, including the multiplexing mode of the SS / PBCH block (SSB) and CORESET#0, the number of occupied RBs, the number of occupied symbols, and the frequency domain offset between the SSB and CORESET#0 (in units of RB). Then, the terminal device can allocate time domain and / or frequency domain resources to CORESET#0 based on this information of CORESET#0, so as to receive the PDCCH corresponding to CORESET#0, as shown in Figures 4 to 7 to be described in detail later.

[0114] Table 1 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15KHz (minimum channel bandwidth 5MHz)

[0115]

[0116]

[0117] It should be noted that, in the case of limited / reduced bandwidth, if the coverage of edge users is improved, it is necessary to increase the number of resources occupied by the control resource set (CORESET#0 in this application). In the case where the frequency domain bandwidth is already limited, it is necessary to consider increasing the number of time slot symbols occupied by CORESET#0. Therefore, the indication of resource information related to CORESET#0 (for example, as shown in Table 1) also needs to be improved accordingly. In addition, under the same bandwidth, the number of RBs occupied by CORESET#0 with different subcarrier spacings (SCS) will also be different. Therefore, it is also necessary to consider how to improve the indication of resource information related to CORESET#0 (such as PDSCH) under different subcarrier spacings of a given bandwidth.

[0118] In an embodiment of the present application, the first indication information (e.g., MIB) that meets the preset conditions may refer to indication information (also referred to as resource information) that meets the above-mentioned resource allocation. That is, the indication information of the relevant resources of CORESET#0 can meet the following requirements: effectively increasing the number of resources occupied by CORESET#0 under limited bandwidth conditions so as to improve insufficient initial access bandwidth and / or insufficient coverage.

[0119] In one possible implementation, in step S301, satisfying the preset condition includes at least one of the following: the first indication information indicates resource information of a control resource set corresponding to a physical downlink control channel; the number of symbols occupied by the control resource set indicated by the first indication information in the time domain is greater than or equal to a first preset value; and the number of resource blocks occupied by the control resource set indicated by the first indication information in the frequency domain is any one of a preset value set. The following describes in detail the technical features of the preset condition from three aspects: resource information of the control resource set, a specific first preset value, and a preset value set.

[0120] (1) Meeting the preset conditions includes the first indication information indicating resource information of a control resource set corresponding to a physical downlink control channel:

[0121] In an embodiment of the present application, the resource information of the control resource set corresponding to the physical downlink control channel indicated by the first indication information may include at least one of the following: the time domain position of the control resource set, the frequency domain position of the control resource set, and the subcarrier spacing of the control resource set. Among them, the time domain position of the control resource set may include the radio frame of the time domain where the control resource set is located (for example, the index of the radio frame) and / or the number of symbols occupied by the control resource set in the time domain. The frequency domain position of the control resource set may include the frequency domain starting position of the control resource set (for example, the index of the resource block at the starting position), the number of resource blocks occupied by the frequency domain of the control resource set, and / or the frequency domain offset between the synchronization signal block and the control resource set (for example, in units of the number of resource blocks). In addition, the subcarrier spacing configuration of the control resource set may be represented in the form of an index corresponding to the numerical value of the subcarrier spacing.

[0122] Of course, the time domain position of the control resource set, the frequency domain position of the control resource set and the subcarrier spacing of the control resource set may also include other relevant information and / or be expressed in other forms. The above is only an example and the present application is not limited thereto.

[0123] In one embodiment, when the resource information of the control resource set corresponding to the physical downlink control channel indicated by the first indication information includes at least one of the time domain position of the control resource set, the frequency domain position of the control resource set, and the subcarrier spacing of the control resource set, the preset condition is satisfied. For example, it can be pre-set as needed: when the resource information of the control resource set includes which specific information or the specific information meets which conditions, the preset condition is satisfied. For example, satisfying the preset condition may mean that the resource information of the control resource set includes the frequency domain starting position of the control resource set. Of course, the present application is not limited to this. For example, satisfying the preset condition may also be as described below (2)(3).

[0124] (2) Meeting the preset condition includes the number of symbols occupied by the control resource set time domain being greater than or equal to a first preset value:

[0125] In an embodiment of the present application, the number of symbols occupied by the control resource set time domain is greater than or equal to the first preset value, which may mean that the number of symbols occupied by the control resource set time domain is increased compared to the number specified in the existing protocol (for example, 1, 2 or 3 time slot symbols). Accordingly, the first preset value can be 1, 2 or 3.

[0126] Optionally, the first preset value can be configured as 3. Since CORESET#0 in the existing protocol usually occupies 1 to 3 time slot symbols, when the preset condition is met, which means that the number of symbols occupied by the control resource set time domain is greater than 3, the mapping table of CORESET#0 in the existing protocol is no longer applicable. In an embodiment of the present application, for this scenario, a new resource mapping table for CORESET#0 is proposed to cover the case where the number of symbols occupied by the CORESET#0 time domain is greater than 3. For example, Table 1 above adds resource information to include the case where the number of symbols occupied by the CORESET#0 time domain is 4, as shown in the bold numbers in Table 1, that is, indexes 6-8 correspond to the case where the number of symbols occupied by the CORESET#0 time domain is 4.

[0127] As described above, Table 1 shows resource information when the maximum number of symbols occupied by the CORESET#0 time domain is 4. However, the present application is not limited thereto, and a table of resource information corresponding to the maximum number of symbols occupied by the CORESET#0 time domain is greater than 4 may also be provided.

[0128] Optionally, Table 2 below shows resource information when the maximum number of symbols occupied by the CORESET#0 time domain is X, where X is a positive integer. As indicated by the bold numbers in Table 2, Table 2 includes resource information for more cases where the number of symbols occupied by the CORESET#0 time domain is greater than 4.

[0129] Table 2 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15KHz (minimum channel bandwidth 5MHz, increased index bits)

[0130]

[0131]

[0132] In one embodiment, assuming that CORESET #0 starts at the beginning of a time slot, the value of X may affect whether CORESET #0 and the corresponding PDSCH are in the same time slot. For example, the following situations may occur: i) when X is less than 14, CORESET #0 and the PDSCH may or may not be in the same time slot; ii) when X = 14, CORESET #0 and the PDSCH are not in the same time slot; iii) when X is greater than 14, if the value of X mod 14 is less than 14, it corresponds to situation i), and if the value of X mod 14 is equal to 14, it corresponds to situation ii). The impact of whether CORESET #0 and the PDSCH are in the same time slot on PDSCH scheduling will be further described below.

[0133] Optionally, the number of bits indicating the index of CORESET#0 in the pdcchConfigSIB1 field can be modified from 4 to 5 to indicate resource information for more cases where the number of symbols occupied by the CORESET#0 time domain is greater than 7 (X≥7), as shown in Table 2.

[0134] Optionally, a 4-bit pdcchConfigSIB1 field may be used without increasing the number of index bits. For example, the configuration of resource information may be further improved in the case of a 4-bit index, as shown in Table 3 below (as indicated by the bold numbers in the table). This improvement is sufficient when the number of symbols occupied by CORESET#0 is not required to be high.

[0135] Table 3 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15 kHz (minimum channel bandwidth 5 MHz, no increase in index bits)

[0136]

[0137]

[0138] (3) The preset conditions include the number of resource blocks occupied by the frequency domain of the control resource set being any one of the preset value sets:

[0139] In an embodiment of the present application, the preset value set may be the number of resource blocks under different channel conditions (for example, given different bandwidths and subcarrier spacings). In this case, if the number of resource blocks occupied by the frequency domain of the control resource set indicated by the first indication information satisfies the preset condition (i.e., is any one of the preset value set), it may indicate a change (for example, a decrease) in the number of resource blocks occupied by the frequency domain resources of the control resource set.

[0140] Optionally, the preset value set can be configured as {6, 12, 24}. Typically, when the SCS is 15KHz, according to a typical transmission bandwidth configuration, a 5MHz bandwidth supports a maximum of 24 RBs. When the SCS is increased to 30KHz, according to a typical transmission bandwidth configuration, a 5MHz bandwidth corresponds to 11 RBs. Therefore, taking into account the limited system bandwidth, the number of frequency domain RBs can be selected within a limited preset range (e.g., a preset value set). For example, it is considered that any one item can be selected from the preset value set {6, 12, 24} as the number of RBs used for CORESET#0 transmission with an SCS of 15KHz or 30KHz under a 5MHz bandwidth. However, the preset value set {6, 12, 24} is merely an example, and the preset value set may also include one or more other values ​​according to actual needs, and the present application is not limited thereto.

[0141] Optionally, when the SCS of the PDCCH corresponding to CORESET#0 is 30 KHz and the number of RBs occupied by its frequency domain is 6 in the preset value set {6, 12, 24}, the corresponding resource information is as shown in Table 4.

[0142] Table 4 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are 15KHz and 30KHz respectively (minimum channel bandwidth 5MHz)

[0143]

[0144]

[0145] Optionally, when the SCS of the PDCCH corresponding to CORESET#0 is 30KHz and the number of RBs occupied by the frequency domain of CORESET#0 is 6, the number of symbols occupied by the time domain of CORESET#0 can be increased with reference to Tables 1 to 3. For example, the number of symbols occupied by the time domain of CORESET#0 can be increased to 4 or other values ​​to ensure the available resources of CORESET#0 under 5MHz bandwidth, as shown in the following Table 5:

[0146] Table 5 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are 15KHz and 30KHz respectively (minimum channel bandwidth 5MHz)

[0147]

[0148] Optionally, satisfying the preset condition includes that the number of resource blocks occupied by the control resource set in the frequency domain is any one of a preset value set, and the number of resource blocks occupied by the control resource set in the frequency domain is used to determine a frequency domain offset reference value, and the frequency domain offset reference value is used to determine the frequency domain offset between the synchronization signal block and the control resource set; optionally, the frequency domain offset reference value S is:

[0149]

[0150] Wherein, R represents the number of resource blocks occupied by the frequency domain of the control resource set, and μ represents the subcarrier spacing configuration of the control resource set. In the embodiment of the present application, the corresponding relationship between the value of the subcarrier spacing configuration μ and the value of the subcarrier spacing Δf is shown in Table 6 below. Table 6 Correspondence between the value of the subcarrier spacing configuration μ and the value of the subcarrier spacing

[0151] μΔf=2 μ 15[kHz]015130260

[0152] 3120424054806960

[0153] In an embodiment of the present application, the frequency domain offset between the synchronization signal block and the control resource set may be a function of a fixed value and a frequency domain offset reference value S. For example, the frequency domain offset may be the sum of the fixed value and the frequency domain offset reference value S. However, the present application is not limited thereto, and the frequency domain offset may also be determined based on other algorithms according to the fixed value and the frequency domain offset reference value S. In this embodiment, the fixed value may be selected from a fixed value set, for example, the fixed value set is {-2, 0, 2} or {-2, -1, 1, 2}. In this embodiment, the fixed value set may be related to the subcarrier spacing of SSB and CORESET#0. For example, when the subcarrier spacing of SSB and CORESET#0 are both configured to be 15 kHz, the fixed value set may be configured to be {-2, 0, 2}, and the value of the frequency domain offset is: S+{-2, 0, 2}. For example, when the subcarrier spacing of SSB and CORESET#0 is configured as 15 kHz and 30 kHz respectively, the fixed value set can be configured as {-2,-1,1,2}, and the frequency domain offset value is: S+{-2,-1,1,2}. The frequency domain offset reference value S can be determined according to formula (1).

[0154] Examples of determining the frequency domain offset based on a fixed value and a frequency domain offset reference value S as described above can be provided in Tables 7 and 8 below. The symbol number column in Tables 7 and 8 is for illustrative purposes only, and the present application is not limited thereto. The value in the symbol number column may be changed according to the method provided in this application (e.g., the method described above). In Tables 7 and 8, offset (RB) represents the frequency domain offset between the synchronization signal block and the control resource set.

[0155] Table 7 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15KHz (minimum channel bandwidth 5MHz)

[0156]

[0157] Table 8 RB set and time slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are 15KHz and 30KHz respectively (minimum channel bandwidth 5MHz)

[0158]

[0159] In one possible implementation, for example, based on Table 4 or Table 5 or Table 7 or Table 8, the reception of the physical downlink control channel in step S302 of the method may include: determining the frequency domain position of the control resource set based on the frequency domain position of the synchronization signal block, the frequency domain offset between the synchronization signal block and the control resource set (for example, indicated by the first indication information), and at least one of the number of resource blocks in the control resource set.

[0160] It should be noted that the above considers the possible mapping rules that need to be satisfied by the time domain mapping and frequency domain mapping of CORESET#0 in the scenario where the number of symbols occupied by the time domain of CORESET#0 increases and / or the number of RBs occupied by the frequency domain decreases. The following will further consider the impact of the resource allocation of PDSCH that may be brought about by the increase in the number of CORESET#0 symbols, especially the resource allocation of DMRS on PDSCH. The following will be introduced based on the time domain mapping position of the DMRS indicated by the dmrs-typeA-position field contained in the first indication information (e.g., MIB).

[0161] In an embodiment of the present application, as described above, the first indication information (e.g., MIB) can indicate the index (l0) of the starting symbol of the first DMRS through the dmrs-typeA-position field, where the first DMRS refers to the first DMRS of the PDSCH in the time domain (also called PDSCH DMRS).

[0162] In a possible implementation manner, the index of the starting symbol of the first DMRS is the first identifier or the second identifier.

[0163] In this embodiment of the present application, the index (l0) of the starting symbol of the first DMRS can be indicated by the dmrs-typeA-position field as "pos2" (first identifier) ​​or "pos3" (second identifier).

[0164] Optionally, the values ​​of "pos2" and "pos3" may be fixed values. For example, dmrs-typeA-position='pos2' may indicate that the value of l0 is 2, while dmrs-typeA-position='pos3' may indicate that the value of l0 is 3.

[0165] In the embodiment of the present application, one of "pos2" and "pos3" can be selected to indicate l0 according to actual needs (such as the number of symbols occupied by the CORESET#0 time domain). For example, when the number of CORESET#0 symbols is less than 3, the network device configures dmrs-typeA-position = 'pos2'; when the number of CORESET#0 symbols is greater than or equal to 3, the network device configures dmrs-typeA-position = 'pos3'.

[0166] Optionally, "pos2" and "pos3" may also take other values, for example, they may vary according to actual needs (such as channel conditions). For example, when the reference signal received power (RSRP) reaches a first preset threshold (for example, indicating that the channel conditions are good enough), the network device configures dmrs-typeA-position = 'pos2'; when the RSRP is lower than the second preset threshold (for example, indicating that the channel conditions are not good enough) or the terminal deployment scenario, the network device configures dmrs-typeA-position = 'pos3'. However, these situations are merely examples and the present application is not limited thereto.

[0167] It should be noted that, after the position of the starting symbol of the first DMRS is obtained as described above, resource information of the PDSCH carrying the first DMRS also needs to be determined.

[0168] As shown in FIG3 , in a possible implementation, the method may further include:

[0169] S303 (as shown by the dotted line in FIG3 ): Receive second indication information. The second indication information indicates at least one of the following items of the physical downlink shared channel: the index of the starting symbol, the symbol length, and the time slot offset between the physical downlink control channel and the physical downlink shared channel.

[0170] In an embodiment of the present application, step S303 may be performed before, after, or simultaneously with step S301, but the present application is not limited thereto. The second indication information may be received by the terminal device from the network device, and the second indication information may be downlink control information (DCI). As DCI, the second indication information may be obtained on the PDCCH channel and may include at least a configuration corresponding field, a time domain resource assignment field, for time domain resource allocation of the PDSCH. This field may provide an index (row index) to indicate (for example, according to dmrs-typeA-position) relevant information of the time domain resource allocation of the PDSCH, as shown in Table 9 or Table 10, including the PDSCH mapping type (for example, TypeA or TypeB), the index of the starting symbol of the PDSCH (S, in symbols), the symbol length of the PDSCH (L, in symbols), and the time slot offset (K0, in number of time slots) between the PDSCH and the corresponding PDCCH.

[0171] Table 9 and Table 10 are examples assuming that the number of symbols occupied by CORESET#0 is 4, wherein Table 9 is for the case of a normal cyclic prefix (CP), and Table 10 is for the case of an extended CP.

[0176]

[0177]

[0178] NOTE 1: When dmrs-TypeA-Position = 3 ("pos3"), whether S is 3 or 4 depends on whether the number of symbols of CORESET#0 is 3 or 4.

[0179] Refer to Table 9 and Table 10 to further describe how to determine the index of the starting symbol of the first DMRS according to the dmrs-TypeA-Position field in the first indication information (MIB). As mentioned above, the index of the starting symbol of the first DMRS can be indicated by the dmrs-TypeA-Position field as a first identifier or a second identifier, i.e., "pos2" (or "2" in the table) or "pos3" (or "3" in the table). In addition, the first identifier ("pos2") and / or the second identifier ("pos3") can be flexibly defined without conflicting with the first DMRS in CORESET#0, and one of them can be flexibly selected to indicate the index of the starting symbol of the first DMRS. Based on this understanding, the first identifier and / or the second identifier are described in detail below.

[0180] Optionally, when the time slot offset between CORESET#0 and PDSCH is 0 and / or the number of symbols occupied by the CORESET#0 time domain is less than or equal to 2, the value of the first identifier ("pos2") may be 1 or 2. Optionally, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by the CORESET#0 time domain is less than or equal to 2, dmrs-TypeA-Position may take the first identifier "pos2", and the value of "pos2" may be 1 or 2. Optionally, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by the CORESET#0 time domain is less than or equal to 2, the first identifier ("pos2") takes a fixed value of 2. Optionally, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by the CORESET#0 time domain is less than or equal to 2, the first identifier ("pos2") can be flexibly interpreted as 1 or 2. For example, when the number of symbols occupied by the CORESET#0 time domain = 1, "pos2" indicates that the starting symbol index of the first DMRS of PDSCH is 1; when the number of symbols occupied by the CORESET#0 time domain = 2, "pos2" indicates that the starting symbol index of the first DMRS of PDSCH is 2.

[0181] Optionally, when the number of symbols occupied by the CORESET#0 time domain is greater than 3, the value of the second identifier ("pos3") may be the number of symbols occupied by the CORESET#0 time domain. For example, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by the CORESET#0 time domain is greater than or equal to 3, dmrs-TypeA-Position takes the second identifier "pos3", and the value of "pos3" may be the number of symbols occupied by the CORESET#0 time domain. For example, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by the CORESET#0 time domain is 4, "pos3" indicates that the starting symbol index of the first DMRS of PDSCH is 4.

[0182] Optionally, when the index (S) of the starting symbol of the PDSCH is greater than the number of symbols occupied by CORESET#0, the value of the second identifier ("pos3") can be the maximum value of the number of symbols occupied by the CORESET#0 time domain and the index (S) of the starting symbol. For example, when CORESET#0 and PDSCH are in the same time slot and the index (S) of the starting symbol of the PDSCH is greater than the number of symbols occupied by the CORESET#0 time domain, the dmrs-TypeA-Position takes the second identifier "pos3", and the value of "pos3" can be the maximum value of the number of symbols occupied by the CORESET#0 time domain and the index (S) of the starting symbol of the PDSCH. For example, when CORESET#0 and PDSCH are in the same time slot, and the number of symbols occupied by the "pos3" CORESET#0 time domain is 3 and the index (S) of the starting symbol of the PDSCH is 4, the value of "pos3" is max{3,4}=4, that is, the index of the first DMRS is 4.

[0183] Optionally, when the value of the time slot offset between CORESET#0 and PDSCH is not 0, the value of dmrs-TypeA-Position can be determined as the first identifier ("pos2") or the second identifier ("pos3") according to the channel condition (for example, the value of RSRP). In addition, the value of "pos2" can be 0, 1, or 2, and the value of "pos3" is 3. That is, when the PDCCH and PDSCH corresponding to CORESET#0 are not in the same time slot, the value of "pos2" is determined according to the actual terminal deployment scenario, for example, the fixed value of "pos2" is 0.

[0184] In summary, the definition and / or selection of the first identifier and the second identifier are not limited to the above optional situations and / or examples, and other definitions / selections may be made depending on the circumstances.

[0185] In the embodiment of the present application, the combination of the index (S) and the symbol length (L) of the starting symbol of the PDSCH in the time slot indicated by the second indication information should be valid, for example, should be feasible.

[0186] Optionally, taking the maximum number of symbols of CORESET#0 as 4 as an example, the valid combination values ​​of S and L are given in Table 11.

[0187] Table 11 Valid combinations of S and L

[0188]

[0189] Optionally, according to the number of symbols occupied by different CORESET#0 time domains, a mapping table of the PDSCH start symbol and the symbol length occupied in a time slot that conforms to certain rules is set. Taking the maximum number of symbols of CORESET#0 as an example, which is 4, the valid combinations of the index (S) and symbol length (L) of the starting symbol of the PDSCH in the time slot are shown in Tables 9 and 10, where Table 9 is for normal CP and Table 10 is for extended CP.

[0190] Optionally, taking the maximum number of symbols of CORESET#0 as X as an example (X is a positive integer), the valid combination values ​​of S and L are given in Table 12.

[0191] Table 12 Valid combinations of S and L

[0192]

[0193] Please refer to Figure 4, which is a schematic diagram of an example resource allocation of a downlink control channel and a downlink shared channel according to an embodiment of the present application, and is described below in conjunction with the method of the present application.

[0194] Optionally, Figure 4 shows the time domain resource allocation when CORESET#0 and PDSCH are in the same time slot (K0=0). In the example of Figure 4, the symbol of PDSCH is based on 1 RB in the frequency domain (optionally, the case of multiple RBs in the frequency domain is the same as the frequency domain distribution of 1 RB), and the first preset value is 2.

[0195] The resource allocation shown in FIG4 can be obtained according to the method proposed in this application.

[0196] First, in step S301, MIB (first indication information) is received, and the index value of the CORESET#0 mapping in the field pdcch-ConfigSIB1 is obtained. In this example, the index value is 6. It can be seen from Table 1 that the number of symbols occupied by the CORESET#0 time domain is 4, and is greater than or equal to the first preset value 2, that is, the received first indication information meets the preset conditions. The frequency domain range of CORESET#0 can be determined according to the frequency domain offset and the number of RBs occupied by the frequency domain of SSB and CORESET#0 in Table 1, and then PDCCH is received in step S302.

[0197] Secondly, in step S301, the value of the field dmrs-TypeA-Position can also be obtained in the received MIB (first indication information). In this example, dmrs-TypeA-Position = 'pos3', and the interpretation of 'pos3' is the number of symbols occupied by the CORESET#0 time domain. Assuming that the CP type is NCP, the DMRS configuration type is typeA, and the DMRS is single-symbol, then DCI (second indication information) can also be received in step S303. According to the Row index = 2 corresponding to the Time domain resource assignment field and the field dmrs-TypeA-Position = 'pos3', it can be seen from Table 9 that the starting symbol S of the PDSCH is 4 and the symbol duration L occupied by the PDSCH is 8. Therefore, receiving the PDCCH according to the first indication information that meets the preset conditions in step S302 may include: receiving the PDCCH and the PDSCH associated with the PDCCH according to the first indication information and the second indication information that meet the preset conditions.

[0198] As shown in FIG4 , in the time domain, the first 4 symbols in the slot are used to receive PDCCH, the last 8 symbols are used to receive PDSCH, and the DMRS of PDSCH starts from the 5th (ie index 4) symbol in the slot.

[0199] Please refer to Figure 5, which is a schematic diagram of an example resource allocation of a downlink control channel and a synchronization signal block according to an embodiment of the present application, and is described below in combination with the method of the present application.

[0200] Optionally, FIG5 shows a schematic diagram of determining the frequency domain position of CORESET#0 based on the frequency domain offset between SSB and CORESET#0. In the example of FIG5 , assuming that the channel bandwidth is 5 MHz, the SCS of CORESET#0 is 30 kHz, the SCS of SSB is 15 kHz, and the preset value set of the number of RBs occupied by the frequency domain of CORESET#0 is {6, 12, 24}, as shown in Table 4.

[0201] The resource allocation shown in FIG5 can be obtained according to the method proposed in this application.

[0202] First, in step S301, the MIB (first indication information) is received and the value of the pdcch-ConfigSIB1 field is obtained. In this example, pdcch-ConfigSIB1 is 2. According to Table 4, the number of RBs occupied by the CORESET#0 frequency domain is 6, which belongs to the preset value set {6, 12, 24}. That is, the received first indication information meets the preset conditions. Then, in step S302, PDCCH reception can be performed based on the information obtained from the MIB.

[0203] Secondly, in step S301, the received MIB (first indication information) can also obtain the frequency domain offset between CORESET#0 and SSB and the number of time domain symbols and time domain position of CORESET#0. In this example, the obtained frequency domain offset between SSB and CORESET#0 is -3 RBs and the number of time domain symbols of CORESET#0 is 2, as shown in Figure 5. Then, receiving the PDCCH in step S302 may include: determining the frequency domain position of CORESET#0 based on the frequency domain offset between SSB and CORESET#0, determining the time domain position of PDCCH reception based on the number of time domain symbols and time domain position of CORESET#0, and then receiving the PDCCH based on the determined time-frequency domain position of the PDCCH.

[0204] In a possible implementation, the value of the time slot offset between the PDCCH and the PDSCH indicated in the second indication information received in step S303 can be a fixed value or a value corresponding to the subcarrier spacing configuration μ of the PDSCH. PDSCH For example, let the PDCCH and PDSCH time slot offset (K0) be j, where j is a positive integer. Then j can take a fixed value (such as 1) or a value that is consistent with the PDSCH subcarrier spacing configuration μ. PDSCH Other values ​​related to slot offset j and subcarrier spacing configuration μ PDSCH The corresponding relationship between them is shown in Table 13. Among them, the subcarrier spacing configuration μ PDSCH The value of can indicate the size of different subcarrier spacings, as shown in the values ​​in brackets in Table 13.

[0205] Table 13 Definition of j value

[0206] μ PDSCH j

[0207] 0(15KHz)11(30KHz)12(60KHz)23(120KHz)3

[0208] Optionally, when K0=j (j>0) indicated in the second indication information received in step S303, that is, the PDCCH corresponding to COSERT#0 and the corresponding PDSCH are not in the same time slot, the time domain position of the DMRS (e.g., the first DMRS) of the PDSCH can be as follows: dmrs-TypeA-Position='pos2' corresponds to the index of the starting symbol of the first DMRS being 2, or dmrs-TypeA-Position='pos3' corresponds to the index of the starting symbol of the first DMRS being 3. Accordingly, the PDSCH time domain starting symbol and the occupied symbol length can be as shown in Table 14 or Table 15 for the time domain mapping of the PDSCH.

[0209] Table 14 Default PDSCH time domain resource allocation for normal CP A

[0210]

[0211] Table 15 Default PDSCH time domain resource allocation for extended CP A

[0212]

[0213]

[0214] Optionally, when K0=j (j>0) indicated in the second indication information received in step S303, the value of the first identifier ("pos2") may also be 0 or 1. In the embodiment of the present application, referring to Table 14 and Table 15, as described above, when the value of the time slot offset indicated by the second indication information (e.g., DCI) is not 0 (e.g., K0=j, j>0), the value of the first identifier ("pos2") is 0. That is, DMRS is placed at the beginning of the time slot to facilitate early channel estimation of PDSCH, while also increasing the number of DMRS symbols to ensure the accuracy of channel estimation. Accordingly, the index (S) of the starting symbol of PDSCH may also be fixed to 0. For the mapping rules when the PDSCH starting symbol index is 0, refer to Table 16 and Table 17 (as shown in the case of S=0).

[0215] FIG6 is a schematic diagram showing another example resource allocation of a downlink control channel and a downlink shared channel according to an embodiment of the present application, which is described below in conjunction with the method of the present application.

[0216] Optionally, Figure 6 shows an example resource allocation when CORESET#0 and PDSCH are not in the same time slot (K0=j=1). In the example of Figure 6, the symbol of PDSCH is in units of 1 RB in the frequency domain (optionally, the case of multiple RBs in the frequency domain is the same as the frequency domain distribution of 1 RB), and the first preset value is 2.

[0217] The resource allocation shown in FIG6 can be obtained according to the method proposed in this application.

[0218] First, in step S301, the MIB (first indication information) is received and the index value of the CORESET#0 mapping in the pdcch-ConfigSIB1 field is obtained. In this example, the index value is 3. Table 1 shows that the number of symbols occupied by the CORESET#0 time domain is 3 and is greater than or equal to the first preset value 2, that is, the received first indication information meets the preset conditions. Table 1 shows that the frequency domain offset between the SSB and CORESET#0 is 0. Then, based on the frequency domain offset between the SSB and CORESET#0 and the number of RBs occupied by the frequency domain in Table 1, the frequency domain range of CORESET#0 can be determined, and then PDCCH reception is performed in step S302.

[0219] Secondly, in step S301, the field dmrs-TypeA-Position can also be obtained in the received MIB (first indication information). In this example, the value dmrs-TypeA-Position = 'pos3', and the interpretation of 'pos3' is 3. Assuming that the CP type is NCP, the DMRS configuration type is typeA, and the DMRS is single-symbol, then DCI (second indication information) can also be received in step S304. According to the Row index = 2 corresponding to the Time domain resource assignment field and the field dmrs-TypeA-Position = 'pos3', it can be seen from Table 14 that the starting symbol S of the PDSCH is 3 and the symbol duration L occupied by the PDSCH is 9. Therefore, receiving the PDCCH according to the first indication information that meets the preset conditions in step S302 can include: receiving the PDCCH and the PDSCH associated with the PDCCH according to the first indication information and the second indication information that meet the preset conditions.

[0220] As shown in Figure 6, in the time domain, the first three symbols of time slot n are used to receive the PDCCH, and the last nine symbols of time slot n+1, which is offset by one time slot from time slot n, are used to receive the PDSCH. The DMRS of the PDSCH starts from the fourth symbol (i.e., index 3) of time slot n+1. In the case where CORESET#0 and PDSCH are not in the same time slot, it is also possible to consider extending the number of symbols occupied by the time domain of CORESET#0 (for example, up to a maximum of 14) to increase the time domain resources occupied by CORESET#0.

[0221] Table 16 Default PDSCH time domain resource allocation for normal CP A

[0222]

[0223]

[0224] Table 17 Default PDSCH time domain resource allocation for extended CP A

[0225]

[0226] Please refer to Figure 7, which is a schematic diagram of another example resource allocation of a downlink control channel and a downlink shared channel according to an embodiment of the present application, and is described below in conjunction with the method of the present application.

[0227] Optionally, Figure 7 shows an example resource allocation when CORESET#0 and PDSCH are not in the same time slot (K0=j=1). In the example of Figure 7, the symbol of PDSCH is in units of 1 RB in the frequency domain (optionally, the case of multiple RBs in the frequency domain is the same as the frequency domain distribution of 1 RB), and the first preset value is 2.

[0228] The resource allocation shown in FIG. 7 can be obtained according to the method proposed in this application.

[0229] First, in step S301, the MIB (first indication information) is received and the index value of the CORESET#0 mapping in the pdcch-ConfigSIB1 field is obtained. In this example, the index value is 3. Table 1 shows that the number of symbols occupied by the CORESET#0 time domain is 3 and is greater than or equal to the first preset value 2, that is, the received first indication information meets the preset condition. Then, the frequency domain range of CORESET#0 can be determined based on the SSB and the frequency domain offset of CORESET#0 and the number of RBs occupied by the frequency domain in Table 1, and then PDCCH reception is performed in step S302.

[0230] Secondly, in step S301, the field dmrs-TypeA-Position can also be obtained in the received MIB (first indication information). In this example, the value dmrs-TypeA-Position = 'pos3', and the interpretation of 'pos3' is 3. Assuming that the CP type is NCP, the DMRS configuration type is typeA, and the DMRS is single-symbol, then DCI (second indication information) can also be received in step S304. According to the Row index = 2 corresponding to the Time domain resource assignment field and the field dmrs-TypeA-Position = 'pos3', it can be seen from Table 16 that the starting symbol S of the PDSCH is 0 and the symbol duration L occupied by the PDSCH is 9. Therefore, receiving the PDCCH according to the first indication information that meets the preset conditions in step S302 may include: receiving the PDCCH and the PDSCH associated with the PDCCH according to the first indication information and the second indication information that meet the preset conditions.

[0231] As shown in Figure 7, in the time domain, the first three symbols of time slot n are used to receive the PDCCH, and the first nine symbols of time slot n+1, which is offset by 1 time slot from time slot n, are used to receive the PDSCH, and the DMRS of the PDSCH starts from the 4th (i.e., index 3) symbol of time slot n+1. In this case, based on the various implementations described above, other optimizations can also be performed, such as extending the length of L to 14, pre-configuring the field dmrs-TypeA-Position = 'pos3' to indicate that the index of the starting symbol of the first DMRS carried by the PDSCH is 0, and so on.

[0232] It should be noted that, as shown in Table 16 and part of Table 17, when the index (S) of the starting symbol of the PDSCH is 0, the number of DMRS symbols can be further increased.

[0233] Referring back to FIG3 , in one possible implementation, the method further includes:

[0234] Step S304 (as shown by the dotted line in FIG3 ): receiving third indication information. The third indication information is used to determine the position information of the second demodulation reference signal.

[0235] In an embodiment of the present application, the third indication information may be received by the terminal device from the network device, and the third indication information may be radio resource control (RRC) information. As RRC, the second indication information may include at least a configuration corresponding field dmrs-AdditionalPosition for time domain resource allocation of the remaining (multiple) DMRSs in the PDSCH except the first DMRS.

[0236] In this method, the order of the operations of receiving three types of indication information in steps S301, S303 and S304 is not limited to the numerical order of the reference marks, but can be interchanged.

[0237] In one possible implementation, the second demodulation reference signal indicated by the third indication information and the first demodulation reference signal indicated by the first indication information are located in the same time slot, and / or the starting symbol of the second demodulation reference signal is after the starting symbol of the first demodulation reference signal.

[0238] For example, the dmrs-AdditionalPosition field in the third indication information (e.g., RRC) may directly indicate the index of the time slot symbol of the remaining (multiple) DMRS (e.g., by providing a table / mapping), or may indirectly indicate the index of the time slot symbol of the remaining (multiple) DMRS (e.g., by providing a symbol offset from the first DMRS). For example, if the symbol index of the first DMRS is L, and the symbol offset of the second DMRS indicated by this field is A, then the symbol index of the second DMRS in the time slot is L+A, and L+A<14.

[0239] Please refer to Figure 8, which is a flow chart of a processing method according to an embodiment of the present application. As shown in Figure 8, the information processing method includes the following steps S801-S804. The execution subject of the method shown in Figure 8 can be a terminal device (for example, the mobile terminal 100 in Figure 1 or the UE 201 in Figure 2) and a network device (for example, the eNodeB 2021 or 2022 in Figure 2). Alternatively, the execution subject of the method shown in Figure 8 can be a chip in the terminal device and the network device. Figure 8 is illustrated by taking the terminal device and the network device as the execution subject of the method as an example.

[0240] S801: First indication information (eg, sent by a network device) is received (eg, by a terminal device), and the first indication information satisfies a preset condition.

[0241] S802: (For example, after receiving the first information, the terminal device) receives the physical downlink control channel according to the first indication information.

[0242] Optionally, the second indication information and the third indication information may be received in step S803 and step S804 (as shown by the dotted lines in FIG8 ), and then in step S802, the physical downlink control channel may be received based on the first indication information in combination with the second indication information and the third indication information, and the corresponding physical downlink shared channel may also be received based on this information.

[0243] In the embodiment of the present application, the implementation of steps S801-S804 at the terminal device is the same as steps S301-S304. To avoid repetition, only a schematic diagram of the execution of these steps at the terminal device and the network device is shown, and their description is omitted. Similar to steps S301-S304, the order of receiving the three types of indication information in steps S801, S803, and S804 is not limited to the numerical order of the reference numbers, but is interchangeable.

[0244] Please refer to Figure 9, which is a flow chart of another processing method according to an embodiment of the present application. As shown in Figure 9, the information processing method includes the following steps S901-S903. The execution subject of the method shown in Figure 9 can be a terminal device (for example, the mobile terminal 100 in Figure 1 or the UE 201 in Figure 2). Alternatively, the execution subject of the method shown in Figure 9 can be a chip in the terminal device. Figure 9 is illustrated by taking the terminal device as the execution subject of the method as an example.

[0245] S901: In response to received first indication information meeting a preset condition, performing a preset process, wherein the first indication information indicates resource information of a control resource set corresponding to a physical downlink control channel.

[0246] In this embodiment of the present application, the preset process includes determining the frequency domain position of the control resource set based on at least one of the frequency domain position of the synchronization signal block, the frequency domain offset between the synchronization signal block and the control resource set, and the number of resource blocks in the control resource set. Furthermore, referring to the previous description, the preset process may be included in step S302 or S802.

[0247] In a possible implementation, the method further includes:

[0248] S902 (not shown): before executing the preset process, receiving second indication information.

[0249] S903 (not shown): before executing the preset process, receiving third indication information.

[0250] Steps S902 and S903 may be the same as steps S303 and S304 or steps S803 and S804, and their descriptions are omitted to avoid repetition. Similarly, the order of receiving the first indication information in step S901 and the operations of S902 and S903 is not limited to the numerical order of the reference numerals, but is interchangeable.

[0251] Please refer to Figure 10, which is a flow chart of another processing method according to an embodiment of the present application. As shown in Figure 10, the information processing method includes the following steps S1000-S1001. The execution subject of the method shown in Figure 10 can be a terminal device (for example, the mobile terminal 100 in Figure 1 or the UE 201 in Figure 2). Alternatively, the execution subject of the method shown in Figure 10 can be a chip in the terminal device. Figure 10 is illustrated by taking the terminal device as the execution subject of the method as an example.

[0252] S1001: Receive a physical downlink control channel and / or a first demodulation reference signal according to first indication information.

[0253] In a possible implementation, the method further includes, before step S1001:

[0254] S1000: Receive or obtain first indication information.

[0255] In a possible implementation, step S1001 includes: in response to the first indication information satisfying the first preset condition, receiving a physical downlink control channel.

[0261] In a possible implementation, the value of the timeslot offset is related to the subcarrier spacing of the physical downlink shared channel.

[0262] In one possible implementation, the method shown in Figure 10 also includes at least one of the following: when the value of the time slot offset is 0 and / or the number of symbols occupied by the control resource set time domain is less than or equal to 2, the value of the first identifier is 1 or 2; when the value of the time slot offset is not 0, the value of the first identifier is 0; when the number of symbols occupied by the control resource set time domain is greater than 3, the value of the second identifier is the number of symbols occupied by the control resource set time domain; when the index of the starting symbol of the physical downlink shared channel is greater than the number of symbols occupied by the control resource set time domain, the value of the second identifier is the maximum value of the number of symbols occupied by the control resource set time domain and the index of the starting symbol; the frequency domain position of the control resource set is determined based on at least one of the frequency domain position of the synchronization signal block, the frequency domain offset and the number of resource blocks of the control resource set.

[0264] Each feature of the method shown in Figure 10 can be implemented with reference to the detailed description of other embodiments herein, and is not limited to the above simple description of Figure 10. Therefore, the detailed description of each feature above is omitted here.

[0265] Please refer to Figure 11, which is a flow chart of another processing method according to an embodiment of the present application. As shown in Figure 11, the information processing method includes the following steps S1101-S1103. The execution subject of the method shown in Figure 11 can be a network device (for example, eNodeB 2021 or 2022 in Figure 2). Alternatively, the execution subject of the method shown in Figure 11 can be a chip in the network device. Figure 11 is illustrated by taking the network device as the execution subject of the method as an example.

[0266] S1101: Sending first indication information, where the first indication information satisfies a preset condition and indicates resource information of a control resource set corresponding to a physical downlink control channel.
