However, it may still support subcarrier spacing configurations such as 15kHz and 30kHz, resulting in a reduction of available frequency domain resources within the bandwidth.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0080] To better understand the frequency domain resource configuration method disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

[0081] Please see Figure 1a , Figure 1a This application provides a schematic diagram of the architecture of a communication system. The communication system may include, but is not limited to, a first network device, a second network device, and a terminal device. Figure 1a The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1a The communication system shown is exemplified by a network device 101 and a terminal device 102.

[0082] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, fifth-generation mobile communication systems, 5G New Radio systems, or other future new mobile communication systems.

[0083] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a Transmission Reception Point (TRP), a Next Generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a Wireless Fidelity (WiFi) system. This embodiment does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a Central Unit (CU) and a Distributed Unit (DU). The CU can also be called a Control Unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0084] The terminal device 102 in this embodiment is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., or a RedCap UE, an evolved RedCap UE, etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0085] In related technologies, the terminal device's control resource set (CORESET) occupies 1 to 3 consecutive symbols in the time domain, and its frequency domain resources are configured in a manner similar to PDSCH (Physical Downlink Shared Channel) resource allocation type 0. The basic granularity of frequency domain resource allocation is 6 RBs (Resource Blocks).

[0086] Release 18 proposes further reducing the bandwidth of Reduced Capability (RedCap) terminal devices to support low-data-rate and cost-sensitive service types such as factory sensors. At the same time, it may still support subcarrier spacing configurations such as 15KHz and 30KHz, resulting in a reduction of available frequency domain resources within the bandwidth range.

[0087] With a sub-carrier spacing (SCS) of 30 kHz, only 11 radio blocks (RBs) are available within a 5 MHz bandwidth. If the CORESET frequency domain resource configuration method from related technologies is still adopted, configuring CORESET frequency domain resources with a basic granularity of 6 RBs, then for the Physical Downlink Control Channel (PDCCH), some frequency domain resources within the bandwidth may never be utilized, such as... Figure 1b As shown, Figure 1b This is a schematic diagram of frequency domain resource configuration in a related art provided in an embodiment of this application. This reduces the number of REGs included in the CORESET, resulting in the inability to support higher aggregation levels, such as... Figure 1b The highest supported aggregation level (AL) is 2, which affects the coverage and transmission performance of the downlink transmission PDCCH of the terminal device.

[0088] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0089] The frequency domain resource allocation method and apparatus provided in this application will be described in detail below with reference to the accompanying drawings.

[0090] Please see Figure 2 , Figure 2 This is a flowchart illustrating a frequency domain resource configuration method provided in an embodiment of this application. It should be noted that the frequency domain resource configuration method in this embodiment is executed by a terminal device. Figure 2 As shown, the method may include the following steps:

[0091] Step 201: Receive the first instruction information sent by the network device.

[0092] In this embodiment of the application, the terminal device receives first indication information sent by the network device. The first indication information is used to instruct the terminal device to determine the frequency domain resources occupied by the control resource set CORESET.

[0093] Optionally, the first indication information includes at least 1 bit, and each bit of the first indication information can indicate whether the corresponding set of frequency domain resource units is a frequency domain resource occupied by the CORESET.

[0094] In this embodiment of the application, the set of frequency domain resource units includes 6 frequency domain resource units. The frequency domain resource units can be resource blocks (RB), physical resource blocks (PRB), virtual resource blocks (VRB), common resource blocks (CRB), etc.

[0095] Step 202: Based on the first instruction information, determine the frequency domain resources occupied by the control resource set CORESET, wherein the first frequency domain resource among the frequency domain resources occupied by the CORESET is outside the bandwidth supported by the terminal device.

[0096] In this embodiment of the application, the terminal device can determine the frequency domain resources occupied by the CORESET based on the first indication information. The frequency domain resources occupied by the CORESET may include frequency domain resources outside the bandwidth supported by the terminal device. That is, the CORESET resources indicated by the first indication information may exceed the bandwidth supported by the terminal device.

[0097] It is understood that in the embodiments of this application, the bandwidth can be either the bandwidth itself or a portion of the bandwidth (BWP).

[0098] In some implementations, the terminal device can determine the first frequency domain resource based on the second indication information. That is, the terminal device can determine, based on the second indication information, which portion of the frequency domain resource occupied by the CORESET indicated by the first indication information is outside the bandwidth supported by the terminal device, so as to ensure that the transmission of PDCCH is within the bandwidth range supported by the terminal device as much as possible, thereby improving the reliability of information transmission in the downlink channel.

[0099] Optionally, the second indication information includes at least one of the following: the number of PDCCH candidate channels, the number of resources occupied by the PDCCH candidate channels, the number of resource element groups in the resource element group (REG) bundle, and the cyclic displacement parameter of the resource element group (REG).

[0100] Among them, the cyclic displacement parameter of REG can be expressed as n shiftThis indicates the amount of cyclic offset in the REG bundle when REGs are interleaved and mapped to the CCE. The number of REGs in a REG bundle can be represented by the REG bundle size, which can take values ​​such as 2, 3, 6, etc. The cyclic offset parameter of the REG and the number of REGs in the REG bundle can affect the mapping relationship between the Control Channel Element (CCE) and the REGs.

[0101] A REG occupies one RB in the frequency domain and one time-domain symbol in the time domain. Within the CORESET, REGs are numbered first in the time domain and then in the frequency domain, as follows: Figure 3a As shown, Figure 3a This is a schematic diagram of resource particle group numbering provided in an embodiment of this application. Multiple consecutive REGs in the time and / or frequency domains form a REG bundle. Transmissions within a bundle use the same precoding, meaning joint channel estimation can be performed on transmissions within a bundle. A CCE occupies 6 REGs, and mapping from CCE to REG (CCE-to-REG) can be achieved through both interleaving and non-interleaving methods. Figure 3b , Figure 3c and Figure 3d As shown, Figure 3b This application provides a schematic diagram of a CCE-to-REG non-interleaving mapping. Figure 3c and Figure 3d This is a schematic diagram of a CCE-to-REG interleaving mapping provided for an embodiment of this application. The interleaving mapping method involves interleaving through an interleaver, such as... Figure 3c and Figure 3d As shown, Figure 3c and Figure 3d In each REG bundle, the number of REGs L is 2, the number of rows in the interleaver R is 2, and the number of REGs included in the CORESET is... The number of columns is 12, the number of columns C in the interleaver is 3, and each CCE corresponds to 3 REG bundles. Figure 3c The cyclic displacement parameter n in REG shift =0, Figure 3d The cyclic displacement parameter n in REG shift =1.

[0102] In some implementations, the terminal device can determine a target CCE from at least one CCE mapped to by the REG, based on the CCE number. It can also determine a first frequency domain resource based on the REG frequency domain occupancy of the target CCE at least one frequency domain resource unit.

[0103] In some implementations, the terminal device can determine at least one CCE not mapped to a PDCCH candidate channel based on the number of PDCCH candidate channels, and determine that a set number of frequency domain resource units corresponding to the at least one CCE not mapped to a PDCCH candidate channel are outside the bandwidth.

[0104] In some implementations, the terminal device aligns the lowest frequency frequency domain resource unit among the resources occupied by CORESET indicated by the first indication information with the lowest frequency frequency domain resource unit among the bandwidth supported by the terminal device, or aligns the highest frequency frequency domain resource unit among the resources occupied by CORESET with the highest frequency frequency domain resource unit among the bandwidth supported by the terminal device.

[0105] In summary, by receiving the first indication information sent by the network device, the frequency domain resources occupied by the control resource set CORESET are determined according to the first indication information. Among the frequency domain resources occupied by the CORESET, the first frequency domain resources are outside the bandwidth supported by the terminal device. The frequency domain resources occupied by the terminal device's CORESET are allowed to exceed the bandwidth supported by the terminal device, so that the terminal device can support higher aggregation levels as much as possible, effectively improve the transmission performance of the downlink channel, enhance the coverage of the downlink channel, improve the system communication efficiency, effectively reduce resource waste, and improve resource utilization.

[0106] Please see Figure 4 , Figure 4 This is a flowchart illustrating a frequency domain resource configuration method provided in an embodiment of this application. It should be noted that the frequency domain resource configuration method in this embodiment is executed by a terminal device. Figure 4 As shown, the method may include the following steps:

[0107] Step 401: Receive the first instruction information sent by the network device.

[0108] In this embodiment of the application, the terminal device receives first indication information sent by the network device. The first indication information is used to instruct the terminal device to determine the frequency domain resources occupied by the control resource set CORESET.

[0109] Optionally, the first indication information includes at least 1 bit, and each bit of the first indication information can indicate whether the corresponding set of frequency domain resource units is a frequency domain resource occupied by the CORESET.

[0110] In this embodiment, the set of frequency domain resource units includes six frequency domain resource units. These frequency domain resource units can be resource blocks (RBs), physical resource blocks (PRBs), virtual resource blocks (VRBs), common resource blocks (CRBs), etc.

[0111] Step 402: Based on the first instruction information, determine the frequency domain resources occupied by the control resource set CORESET, wherein the first frequency domain resource among the frequency domain resources occupied by the CORESET is outside the bandwidth supported by the terminal device.

[0112] In this embodiment of the application, the terminal device can determine the frequency domain resources occupied by the CORESET based on the first indication information. The frequency domain resources occupied by the CORESET may include frequency domain resources outside the bandwidth supported by the terminal device. That is, the CORESET resources indicated by the first indication information may exceed the bandwidth supported by the terminal device.

[0113] It is understood that in the embodiments of this application, the bandwidth can be the bandwidth or a portion of the bandwidth (BWP).

[0114] Step 403: Determine the target CCE from at least one control channel unit (CCE) mapped to by the resource particle group (REG) according to the number of each CCE.

[0115] The REG frequency domain corresponding to the target CCE occupies at least one frequency domain resource unit.

[0116] In some implementations, the target CCE is the CCE with the highest number after REG mapping.

[0117] In this embodiment, based on the frequency domain resources occupied by the CORESET indicated by the first indication information and the number of symbols occupied in the time domain of the CORESET configured by the network device, at least one REG within the CORESET can be determined. Based on the number of REGs included in the REG bundle (REG bundle size), the cyclic shift parameter n of the REG during interleaving mapping... shift The number of rows in the interleaver, etc., can determine the mapping relationship between at least one REG and at least one CCE.

[0118] It is understood that, in the embodiments of this application, if the mapping between REG and CCE is non-interleaved and all REG bundles can be mapped to CCE, then the REG of the highest frequency domain resource unit in the frequency domain resources occupied by the CORESET will necessarily correspond to the highest numbered CCE among at least one of the mapped CCEs.

[0119] If the mapping from REG to CCE is interleaved, then depending on the aforementioned parameters (the number of REGs included in the REG budle, the cyclic displacement parameter n of the REG during interleaving mapping)... shift The mapping method from REG to CCE may differ depending on factors such as the number of rows in the interleaver.

[0120] As an example, please see Figure 5 , Figure 5 This is a schematic diagram of a CCE-to-REG interleaving mapping provided for an embodiment of this application. For example... Figure 5 As shown, the first indication information indicates that the CORESET occupies 12 frequency domain resource units in the frequency domain, the network device is configured to occupy 3 symbols in the time domain for this CORESET, the REG bundle size is 3, and the bandwidth supported by the terminal device includes 11 frequency domain resource units. Therefore, 3 REGs corresponding to one frequency domain resource unit constitute one REGbundle. The REGs within the CORESET are numbered in a time-domain first, then frequency-domain manner, as follows: Figure 5 REGs numbered 0, 1, and 2 form REG bundle 0; REGs numbered 3, 4, and 5 form REG bundle 1; REGs numbered 6, 7, and 8 form REG bundle 2, and so on. The resources occupied by this CORESET include 36 REGs and 12 REG bundles.

[0121] If the cyclic displacement parameter n of REG shift =1, the interleaver has 2 rows, and after interleaving and mapping, it looks like this. Figure 5 As shown, REG bundle 1 and REG bundle 7 correspond to CCE#0, REG bundle 2 and REG bundle 8 correspond to CCE#1, REG bundle 3 and REG bundle 9 correspond to CCE#2, REG bundle 4 and REG bundle 10 correspond to CCE#3, REG bundle 5 and REG bundle 11 correspond to CCE#4, and REG bundle 6 and REG bundle 0 correspond to CCE#5.

[0122] If the cyclic displacement parameter n of REG shift =0, the interleaver row count is 2, and after interleaving mapping, it is as follows Figure 5 As shown, REG bundle 0 and REG bundle 6 correspond to CCE#0, REG bundle 1 and REG bundle 7 correspond to CCE#1, REG bundle 2 and REG bundle 8 correspond to CCE#2, REG bundle 3 and REG bundle 9 correspond to CCE#3, REG bundle 4 and REG bundle 10 correspond to CCE#4, and REG bundle 5 and REG bundle 11 correspond to CCE#5.

[0123] In some implementations, the target CCE is the highest-numbered CCE after REG mapping, i.e., CCE#5. In this example, the cyclic displacement parameter n in REG... shift When n = 1, the REG corresponding to the target CCE (CCE#5) are REGs numbered 0, 1, 2 (REG bundle 0) and REGs numbered 18, 19, 20 (REG bundle 6); the cyclic displacement parameter n of the REG shift When =0, the REG corresponding to the target CCE (CCE#5) are REGs numbered 15, 16, 17 (REG bundle 5) and REGs numbered 33, 34, 35 (REG bundle 11).

[0124] The REG corresponding to the target CCE occupies at least one frequency domain resource unit in the frequency domain. In this example, the cyclic shift parameter n of the REG... shift When n = 1, the REG corresponding to the target CCE occupies two frequency domain resource units in the frequency domain where REG bundle 0 and REGbundle 6 are located; in the REG's cyclic shift parameter n shift When the value is 0, the REG corresponding to the target CCE occupies two frequency domain resource units in the frequency domain, namely REG bundle 5 and REG bundle 11.

[0125] Step 404: In response to at least one frequency domain resource unit in the frequency domain where the REG frequency domain corresponding to the target CCE is located, including the lowest frequency frequency domain resource unit occupied by the CORESET, determine that at least the lowest frequency frequency domain resource unit is outside the bandwidth supported by the terminal device.

[0126] In this embodiment of the application, if at least one frequency domain resource unit in which the REG frequency domain corresponding to the target CCE is located includes the lowest frequency frequency domain resource unit in the frequency domain resources occupied by the CORESET, that is, including the lowest frequency frequency domain resource unit in the frequency domain resources indicated by the first indication information, it is determined that at least the lowest frequency frequency domain resource unit is outside the bandwidth supported by the terminal device.

[0127] As an example, as mentioned earlier, in this example, the cyclic displacement parameter n in REG shiftWhen = 1, the REGs corresponding to the target CCE (CCE#5) are REGs numbered 0, 1, and 2 (REG bundle 0) and REGs numbered 18, 19, and 20 (REG bundle 6). These REGs occupy two frequency domain resource units in the frequency domain, namely REG bundle 0 and REG bundle 6. The frequency domain resource unit where REG bundle 0 is located is the lowest frequency domain resource unit among the frequency domain resources occupied by the CORESET. It is determined that at least this lowest frequency frequency domain resource unit is outside the bandwidth supported by the terminal device; that is, it is determined that at least the frequency domain resource unit where REG bundle 0 is located is outside the bandwidth supported by the terminal device. In this example, the resources configured for the CORESET occupy 12 frequency domain resource units in the frequency domain, and the bandwidth supported by the terminal device includes 11 frequency domain resource units. Therefore, it is only necessary to determine that one frequency domain resource unit (the frequency domain resource unit where REG bundle 0 is located) is outside the bandwidth supported by the terminal device.

[0128] In some examples, if the difference between the number of frequency domain resource units occupied by the resources configured for CORESET and the number of frequency domain resource units included in the bandwidth supported by the terminal device is N (N>1, where N is a positive integer), then the top N frequency domain resource units sorted from low to high frequency are determined to be outside the bandwidth supported by the terminal device (which necessarily includes the lowest frequency frequency resource unit).

[0129] Step 405: In response to at least one frequency domain resource unit in which the REG frequency domain corresponding to the target CCE is located, including the highest frequency frequency domain resource unit occupied by the CORESET, determine that at least the highest frequency frequency domain resource unit is outside the bandwidth supported by the terminal device.

[0130] In this application embodiment, if at least one frequency domain resource unit in which the REG frequency domain corresponding to the target CCE is located includes the highest frequency domain resource unit among the frequency domain resources occupied by the CORESET, that is, including the highest frequency domain resource unit among the frequency domain resources indicated by the first indication information, it is determined that at least the highest frequency frequency domain resource unit is outside the bandwidth supported by the terminal device.

[0131] As an example, as mentioned earlier, in this example, the cyclic displacement parameter n in REG shiftWhen the value is 0, the REGs corresponding to the target CCE (CCE#5) are REGs numbered 15, 16, and 17 (REG bundle 5) and REGs numbered 33, 34, and 35 (REG bundle 11). These REGs occupy two frequency domain resource units in the frequency domain, namely REG bundle 5 and REG bundle 11. The frequency domain resource unit containing REG bundle 11 is the highest frequency domain resource unit occupied by the CORESET. It is determined that at least this highest frequency frequency domain resource unit is outside the bandwidth supported by the terminal device; that is, at least the frequency domain resource unit containing REG bundle 11 is outside the bandwidth supported by the terminal device. In this example, the resources configured for the CORESET occupy 12 frequency domain resource units, and the bandwidth supported by the terminal device includes 11 frequency domain resource units. Therefore, it is only necessary to determine that one frequency domain resource unit (the frequency domain resource unit containing REG bundle 11) is outside the bandwidth supported by the terminal device.

[0132] In some examples, if the number of frequency domain resource units occupied by the resources configured for CORESET is N (N>1, where N is a positive integer) more than the number of frequency domain resource units included in the bandwidth supported by the terminal device, then the top N frequency domain resource units, sorted from highest to lowest frequency, are determined to be outside the bandwidth supported by the terminal device (which necessarily includes the highest frequency frequency resource unit).

[0133] In summary, by receiving the first indication information sent by the network device, the frequency domain resources occupied by the control resource set CORESET are determined according to the first indication information. Specifically, the first frequency domain resources within the frequency domain resources occupied by the CORESET are outside the bandwidth supported by the terminal device. From at least one control channel unit (CCE) mapped from the resource particle group (REG), a target CCE is determined based on the number of each CCE. Then, based on whether the at least one frequency domain resource unit containing the REG corresponding to the target CCE includes the lowest frequency frequency domain resource unit or the highest frequency frequency domain resource unit within the frequency domain resources occupied by the CORESET, frequency domain resource units outside the bandwidth supported by the terminal device are determined. The frequency domain resources occupied by the terminal device's CORESET are allowed to exceed the bandwidth supported by the terminal device, enabling the terminal device to support higher aggregation levels as much as possible. This effectively improves the transmission performance of the downlink channel, enhances the coverage of the downlink channel, improves system communication efficiency, and ensures that the transmission of the downlink channel is within the bandwidth range supported by the terminal device, thereby improving the reliability of communication transmission, effectively reducing resource waste, and improving resource utilization.

[0134] Please see Figure 6 , Figure 6 This is a flowchart illustrating a frequency domain resource configuration method provided in an embodiment of this application. It should be noted that the frequency domain resource configuration method in this embodiment is executed by a terminal device. Figure 6 As shown, the method may include the following steps:

[0135] Step 601: Receive the first instruction information sent by the network device.

[0136] In this embodiment of the application, the terminal device receives first indication information sent by the network device. The first indication information is used to instruct the terminal device to determine the frequency domain resources occupied by the control resource set CORESET.

[0137] Optionally, the first indication information includes at least 1 bit, and each bit of the first indication information can indicate whether the corresponding set of frequency domain resource units is a frequency domain resource occupied by the CORESET.

[0138] In this embodiment, the set of frequency domain resource units includes six frequency domain resource units. These frequency domain resource units can be resource blocks (RBs), physical resource blocks (PRBs), virtual resource blocks (VRBs), common resource blocks (CRBs), etc.

[0139] Step 602: Based on the first instruction information, determine the frequency domain resources occupied by the control resource set CORESET, wherein the first frequency domain resource among the frequency domain resources occupied by the CORESET is outside the bandwidth supported by the terminal device.

[0140] In this embodiment of the application, the terminal device can determine the frequency domain resources occupied by the CORESET based on the first indication information. The frequency domain resources occupied by the CORESET may include frequency domain resources outside the bandwidth supported by the terminal device. That is, the CORESET resources indicated by the first indication information may exceed the bandwidth supported by the terminal device.

[0141] It is understood that in the embodiments of this application, the bandwidth can be the bandwidth or a portion of the bandwidth (BWP).

[0142] Step 603: Based on the number of candidate channels for the Physical Downlink Control Channel (PDCCH), determine at least one Control Channel Element (CCE) that is not mapped to a candidate channel for the PDCCH.

[0143] In this embodiment of the application, at least one CCE not mapped to a PDCCH candidate channel can be determined based on the number of PDCCH candidate channels, and then frequency domain resources outside the bandwidth range supported by the terminal device can be determined based on the at least one CCE not mapped to a PDCCH candidate channel.

[0144] Several CCEs will be aggregated into a PDCCH. The number of CCEs that are aggregated into a PDCCH is the aggregation level AL. All resources that may be PDCCHs are called PDCCH candidate channels.

[0145] As an example, please see Figure 7 , Figure 7 This is a schematic diagram of a CCE-to-REG interleaving mapping provided for an embodiment of this application. For example... Figure 7 As shown, the first indication information indicates that the CORESET occupies 12 frequency domain resource units in the frequency domain, the network device is configured to occupy 3 symbols in the time domain for this CORESET, the REG bundle size is 3, and the bandwidth supported by the terminal device includes 11 frequency domain resource units. Therefore, 3 REGs corresponding to one frequency domain resource unit constitute one REGbundle. The REGs within the CORESET are numbered in a time-domain first, then frequency-domain manner, as follows: Figure 7 REGs numbered 0, 1, and 2 form REG bundle 0; REGs numbered 3, 4, and 5 form REG bundle 1; REGs numbered 6, 7, and 8 form REG bundle 2, and so on. This CORESET occupies 36 REGs and 12 REG bundles. In this example, the number of PDCCH candidate channels is 1, and the aggregation level AL = 4.

[0146] In this example, the resources occupied by the CORESET include 36 REGs, and each CCE corresponds to 6 REGs. Therefore, the resources occupied by the CORESET include 6 CCEs. In this example, the number of PDCCH candidate channels is 1, the aggregation level AL=4, and CCE#0-CCE#3 are determined to be mapped to the PDCCH candidate channel PDCCH candidate#0. At least one CCE not mapped to the PDCCH candidate channel is determined to be CCE#4 and CCE#5.

[0147] It is understood that, in the embodiments of this application, this example is only an exemplary method for determining at least one CCE that is not mapped to a PDCCH candidate channel. Other methods may be used to determine the CCE in the PDCCH candidate channel and at least one CCE that is not mapped to a PDCCH candidate channel, depending on the communication system and protocol specifications. This is not limited here.

[0148] Step 604: Determine that among the frequency domain resource units corresponding to at least one CCE that is not mapped to the PDCCH candidate channel, the frequency domain resource units with the highest set number of frequencies and / or the frequency domain resource units with the lowest set number of frequencies are outside the bandwidth supported by the terminal device.

[0149] The set number is determined based on the number of frequency domain resource units occupied by the CORESET in the frequency domain as indicated by the first indication information, and the number of frequency domain resource units included in the bandwidth supported by the terminal device.

[0150] It is understandable that the highest frequency setting refers to either setting the number of items first when sorted from highest to lowest frequency, or setting the number of items last when sorted from lowest to highest frequency; the lowest frequency setting refers to either setting the number of items last when sorted from highest to lowest frequency, or setting the number of items first when sorted from lowest to highest frequency.

[0151] In some implementations, the set number is the difference between the number of frequency domain resource units occupied by the resources configured for the CORESET and the number of frequency domain resource units included in the bandwidth supported by the terminal device. That is, the set number N = the number of frequency domain resource units occupied by the resources configured for the CORESET - the number of frequency domain resource units included in the bandwidth supported by the terminal device.

[0152] As a first possible implementation, among the frequency domain resource units corresponding to at least one CCE that is not mapped to a PDCCH candidate channel, the top N frequency domain resource units are sorted by frequency, outside the bandwidth supported by the terminal device. Optionally, this frequency sorting can be from low to high or from high to low.

[0153] As a second possible implementation, among the frequency domain resource units corresponding to at least one CCE that is not mapped to a PDCCH candidate channel, the last N frequency domain resource units are sorted by frequency, outside the bandwidth supported by the terminal device. Optionally, this frequency sorting can be from low to high or from high to low.

[0154] As a third possible implementation, among the frequency domain resource units corresponding to at least one CCE not mapped to a PDCCH candidate channel, the frequency domain resource units are sorted by frequency into the first m and the last (Nm) frequency domain resource units, outside the bandwidth supported by the terminal device. Optionally, this frequency sorting can be from low to high or from high to low. Here, m is a natural number.

[0155] As an example, as mentioned earlier, in this example, if the cyclic displacement parameter n of REG shift =1, the interleaver has 2 rows, and after interleaving and mapping, it looks like this. Figure 7As shown, REG bundle 1 and REG bundle 7 correspond to CCE#0, REG bundle 2 and REG bundle 8 correspond to CCE#1, REG bundle 3 and REG bundle 9 correspond to CCE#2, REG bundle 4 and REGbundle 10 correspond to CCE#3, REG bundle 5 and REG bundle 11 correspond to CCE#4, and REG bundle 6 and REGbundle 0 correspond to CCE#5.

[0156] If the cyclic displacement parameter n of REG shift =0, the interleaver row count is 2, and after interleaving mapping, it is as follows Figure 7 As shown, REG bundle 0 and REG bundle 6 correspond to CCE#0, REG bundle 1 and REG bundle 7 correspond to CCE#1, REG bundle 2 and REG bundle 8 correspond to CCE#2, REG bundle 3 and REG bundle 9 correspond to CCE#3, REG bundle 4 and REG bundle 10 correspond to CCE#4, and REG bundle 5 and REG bundle 11 correspond to CCE#5.

[0157] In this example, the difference N = 1 between the number of frequency domain resource units occupied by the resources configured for CORESET and the number of frequency domain resource units included in the bandwidth supported by the terminal device.

[0158] If the cyclic displacement parameter n of REG shift =1, at least one CCE (CCE#4 and CCE#5) not mapped to a PDCCH candidate channel, whose corresponding frequency domain resource unit is the frequency domain resource unit where REG bundle 5, REG bundle 11, REG bundle 6, and REG bundle 0 are located. In this example, it can be determined that the frequency domain resource unit where REG bundle 0 is located is outside the bandwidth supported by the terminal device, and it can also be determined that the frequency domain resource unit where REG bundle 11 is located is outside the bandwidth supported by the terminal device.

[0159] If the cyclic displacement parameter n of REG shift=0, indicating at least one CCE (CCE#4 and CCE#5) not mapped to a PDCCH candidate channel, with the corresponding frequency domain resource unit being the frequency domain resource unit where REG bundle 4, REG bundle 10, REG bundle 5, and REG bundle 11 reside. In this example, the frequency domain resource unit where REG bundle 11 resides is determined to be outside the bandwidth supported by this terminal device.

[0160] In some examples, if N > 1, where N is a positive integer, for example, if the terminal device supports a bandwidth of 10 frequency domain resource units, then N = 2. If the cyclic shift parameter n of REG... shift =1, in this example, it can be determined that the frequency domain resource units of REG bundle 0 and REG bundle 11 are outside the bandwidth supported by the terminal device. If the cyclic shift parameter n of REG is... shift =0, in this example, it can be determined that the frequency domain resource units where REG bundle 10 and REG bundle 11 are located are outside the bandwidth supported by the terminal device.

[0161] In summary, by receiving the first indication information sent by the network device, the frequency domain resources occupied by the control resource set CORESET are determined according to the first indication information. The first frequency domain resources within the frequency domain resources occupied by the CORESET are outside the bandwidth supported by the terminal device. Based on the number of candidate channels of the Physical Downlink Control Channel (PDCCH), at least one Control Channel Element (CCE) not mapped to a candidate channel of the PDCCH is determined. Among the frequency domain resource units corresponding to the at least one CCE not mapped to a candidate channel of the PDCCH, the highest set number of frequency domain resource units and / or the lowest set number of frequency domain resource units are determined. Since the frequency domain resources occupied by the terminal device's CORESET are outside the bandwidth supported by the terminal device, the frequency domain resources are allowed to exceed the bandwidth supported by the terminal device. This allows the terminal device to support higher aggregation levels as much as possible, effectively improving the transmission performance of the downlink channel, enhancing the coverage of the downlink channel, improving system communication efficiency, ensuring that the transmission of the downlink channel is within the bandwidth range supported by the terminal device, improving the reliability of communication transmission, effectively reducing resource waste, and improving resource utilization.

[0162] Please see Figure 8 , Figure 8 This is a flowchart illustrating a frequency domain resource configuration method provided in an embodiment of this application. It should be noted that the frequency domain resource configuration method in this embodiment is executed by a terminal device. Figure 8 As shown, the method may include the following steps:

[0163] Step 801: Receive the first instruction information sent by the network device.

[0164] In this embodiment of the application, the terminal device receives first indication information sent by the network device. The first indication information is used to instruct the terminal device to determine the frequency domain resources occupied by the control resource set CORESET.

[0165] Optionally, the first indication information includes at least 1 bit, and each bit of the first indication information can indicate whether the corresponding set of frequency domain resource units is a frequency domain resource occupied by the CORESET.

[0166] In this embodiment, the set of frequency domain resource units includes six frequency domain resource units. These frequency domain resource units can be resource blocks (RBs), physical resource blocks (PRBs), virtual resource blocks (VRBs), common resource blocks (CRBs), etc.

[0167] Step 802: Based on the first instruction information, determine the frequency domain resources occupied by the control resource set CORESET, wherein the first frequency domain resource in the frequency domain resources occupied by the CORESET is outside the bandwidth supported by the terminal device; the lowest frequency frequency domain resource unit in the frequency domain resources occupied by the CORESET is aligned with the lowest frequency frequency domain resource unit in the bandwidth supported by the terminal device; or, the highest frequency frequency domain resource unit in the frequency domain resources occupied by the CORESET is aligned with the highest frequency frequency domain resource unit in the bandwidth supported by the terminal device.

[0168] In this embodiment of the application, the terminal device can determine the frequency domain resources occupied by the CORESET based on the first indication information. The frequency domain resources occupied by the CORESET may include frequency domain resources outside the bandwidth supported by the terminal device. That is, the CORESET resources indicated by the first indication information may exceed the bandwidth supported by the terminal device.

[0169] It is understood that in the embodiments of this application, the bandwidth can be the bandwidth or a portion of the bandwidth (BWP).

[0170] In this embodiment of the application, as a first possible implementation, the lowest frequency frequency domain resource unit occupied by the CORESET is aligned with the lowest frequency frequency domain resource unit supported by the terminal device. That is, the starting frequency domain resource unit indicated by the first indication information is the first frequency domain resource unit from low to high frequency of the bandwidth supported by the terminal device.

[0171] In a second possible implementation, the highest frequency domain resource unit occupied by the CORESET is aligned with the highest frequency domain resource unit in the bandwidth supported by the terminal device. That is, the terminating frequency domain resource unit indicated by the first indication information is the last frequency domain resource unit in the bandwidth supported by the terminal device from low to high frequency.

[0172] In summary, by receiving the first indication information sent by the network device, the frequency domain resources occupied by the control resource set CORESET are determined according to the first indication information. Specifically, the first frequency domain resource within the frequency domain resources occupied by the CORESET is outside the bandwidth supported by the terminal device. The lowest frequency unit of the frequency domain resources occupied by the CORESET is aligned with the lowest frequency unit of the bandwidth supported by the terminal device, or the highest frequency unit of the frequency domain resources occupied by the CORESET is aligned with the highest frequency unit of the bandwidth supported by the terminal device. The frequency domain resources occupied by the terminal device's CORESET are allowed to exceed the bandwidth supported by the terminal device, enabling the terminal device to support higher aggregation levels as much as possible, effectively improving the transmission performance of the downlink channel, enhancing the coverage of the downlink channel, improving system communication efficiency, effectively reducing resource waste, and improving resource utilization.

[0173] It should be noted that, because the resource configuration method of CORESET#0 is different from other CORESETs, in the embodiments of this application, if the control resource set CORESET is CORESET#0, then the first indication information is the Remaining Minimum System Information (RMSI). The RMSI signaling is used to determine the frequency domain resource length and the corresponding number of symbols of CORESET#0 from at least one combination of frequency domain resource length and corresponding number of symbols agreed upon in the protocol.

[0174] As an example, when the subcarrier spacing (SCS) is 30 kHz, the combination of at least one frequency domain resource length and the corresponding number of symbols agreed upon in the protocol can be shown in the table below.

[0175]

[0176] Table 1. Frequency domain resource length and corresponding symbol count configuration for CORESET#0

[0177] To improve resource utilization, reduce unnecessary resource waste, and enhance transmission efficiency and quality, when designing the combination of frequency domain resource length and corresponding symbol number for CORESET#0, we can try to ensure that the frequency domain resource length does not exceed the bandwidth supported by the terminal device, and that the number of REGs (i.e., the product of the number of RBs and the number of symbols) included in the combination of frequency domain resource length and corresponding symbol number is as much as possible a multiple of 6, etc.

[0178] It is understood that this table is only an example, exemplarily providing some possible combinations of frequency domain resource lengths and corresponding symbol counts for CORESET#0. More combinations can be designed to meet and adapt to more scenarios and bandwidth requirements. This table is only an example and does not limit the embodiments of this application.

[0179] Please see Figure 9 , Figure 9 This is a flowchart illustrating a frequency domain resource configuration method provided in an embodiment of this application. It should be noted that the frequency domain resource configuration method in this embodiment is executed by a network device. Figure 9 As shown, the method may include the following steps:

[0180] Step 901: Send first indication information to the terminal device. The first indication information is used to determine the frequency domain resources occupied by the control resource set CORESET. The first frequency domain resource occupied by the CORESET is outside the bandwidth supported by the terminal device.

[0181] In this embodiment of the application, the network device sends a first indication information to the terminal device, the first indication information being used to instruct the terminal device to determine the frequency domain resources occupied by the control resource set CORESET.

[0182] Optionally, the first indication information includes at least 1 bit, and each bit of the first indication information can indicate whether the corresponding set of frequency domain resource units is a frequency domain resource occupied by the CORESET.

[0183] In this embodiment, the set of frequency domain resource units includes six frequency domain resource units. These frequency domain resource units can be resource blocks (RBs), physical resource blocks (PRBs), virtual resource blocks (VRBs), common resource blocks (CRBs), etc.

[0184] In this embodiment of the application, the terminal device can determine the frequency domain resources occupied by the CORESET based on the first indication information. The frequency domain resources occupied by the CORESET may include frequency domain resources outside the bandwidth supported by the terminal device. That is, the CORESET resources indicated by the first indication information may exceed the bandwidth supported by the terminal device.

[0185] It is understood that in the embodiments of this application, the bandwidth can be the bandwidth or a portion of the bandwidth (BWP).

[0186] In some implementations, the terminal device aligns the lowest frequency frequency domain resource unit among the resources occupied by CORESET indicated by the first indication information with the lowest frequency frequency domain resource unit among the bandwidth supported by the terminal device, or aligns the highest frequency frequency domain resource unit among the resources occupied by CORESET with the highest frequency frequency domain resource unit among the bandwidth supported by the terminal device.

[0187] In some implementations, the terminal device can determine a target CCE from at least one CCE mapped to by the REG, based on the CCE number. It can also determine a first frequency domain resource based on the REG frequency domain occupancy of the target CCE at least one frequency domain resource unit.

[0188] In some implementations, the terminal device can determine at least one CCE not mapped to a PDCCH candidate channel based on the number of PDCCH candidate channels, and determine that a set number of frequency domain resource units corresponding to the at least one CCE not mapped to a PDCCH candidate channel are outside the bandwidth.

[0189] In this embodiment of the application, if the control resource set CORESET is CORESET#0, then the first indication information is the Remaining Minimum System Message (RMSI). The RMSI signaling is used to determine the frequency domain resource length and the corresponding number of symbols of CORESET#0 from at least one combination of frequency domain resource length and corresponding number of symbols agreed upon in the protocol.

[0190] In summary, by sending a first indication message to the terminal device, the frequency domain resources occupied by the control resource set CORESET are determined. Specifically, the first frequency domain resources occupied by the CORESET are outside the bandwidth supported by the terminal device. The frequency domain resources occupied by the terminal device's CORESET are allowed to exceed the bandwidth supported by the terminal device, enabling the terminal device to support higher aggregation levels as much as possible. This effectively improves the transmission performance of the downlink channel, enhances the coverage of the downlink channel, improves system communication efficiency, effectively reduces resource waste, and increases resource utilization.

[0191] Corresponding to the frequency domain resource configuration methods provided in the above embodiments, this application also provides a frequency domain resource configuration device. Since the frequency domain resource configuration device provided in this application corresponds to the methods provided in the above embodiments, the implementation of the frequency domain resource configuration method is also applicable to the frequency domain resource configuration device provided in the following embodiments, which will not be described in detail in the following embodiments.

[0192] Please see Figure 10 , Figure 10 This is a schematic diagram of a frequency domain resource configuration device provided in an embodiment of this application.

[0193] like Figure 10 As shown, the frequency domain resource configuration device 1000 includes: a transceiver unit 1010 and a processing unit 1020, wherein:

[0194] Transceiver unit 1010 is used to receive first indication information sent by network device;

[0195] The processing unit 1020 is configured to determine the frequency domain resources occupied by the control resource set CORESET according to the first indication information; wherein, the first frequency domain resource among the frequency domain resources occupied by CORESET is outside the bandwidth supported by the terminal device.

[0196] Optionally, the processing unit 1020 is further configured to:

[0197] Based on the second instruction information, determine the first frequency domain resources outside the bandwidth supported by the terminal device from the frequency domain resources occupied by the CORESET;

[0198] The second indication information includes at least one of the following: the number of candidate channels for the Physical Downlink Control Channel (PDCCH), the number of resource particle groups in the resource particle group (REG) bundle, and the cyclic displacement parameter of the resource particle group (REG).

[0199] Optionally, the processing unit 1020 is specifically used for:

[0200] From at least one control channel unit (CCE) mapped to the resource particle group (REG), a target CCE is determined according to the number of each CCE; wherein the REG frequency domain corresponding to the target CCE occupies at least one frequency domain resource unit.

[0201] In response to at least one frequency domain resource unit in which the REG frequency domain corresponding to the target CCE is located, including the lowest frequency frequency domain resource unit in the frequency domain resources occupied by the CORESET, it is determined that at least the lowest frequency frequency domain resource unit is the first frequency domain resource outside the bandwidth supported by the terminal device;

[0202] In response to at least one frequency domain resource unit in which the REG frequency domain corresponding to the target CCE is located, including the highest frequency frequency domain resource unit occupied by the CORESET, at least the highest frequency frequency domain resource unit is determined to be the first frequency domain resource outside the bandwidth supported by the terminal device.

[0203] Optionally, the processing unit 1020 is specifically used for:

[0204] Based on the number of Physical Downlink Control Channel (PDCCH) candidate channels, determine at least one Control Channel Element (CCE) that is not mapped to a PDCCH candidate channel;

[0205] Among the frequency domain resource units corresponding to at least one CCE that is not mapped to the PDCCH candidate channel, the frequency domain resource units with the highest set number of frequencies and / or the frequency domain resource units with the lowest set number of frequencies are determined to be the first frequency domain resources outside the bandwidth supported by the terminal device.

[0206] Optionally, the lowest frequency domain resource unit occupied by the CORESET is aligned with the lowest frequency domain resource unit supported by the terminal device; or,

[0207] The highest frequency domain resource unit occupied by the CORESET is aligned with the highest frequency domain resource unit in the bandwidth supported by the terminal device.

[0208] Optionally, the control resource set CORESET is CORESET#0, the first indication information is the minimum residual system message RMSI, and the first indication information is used to determine the frequency domain resource length and the corresponding number of symbols of CORESET#0 from at least one combination of frequency domain resource length and corresponding number of symbols agreed upon by the protocol.

[0209] The frequency domain resource configuration device in this embodiment can receive first indication information sent by a network device and determine the frequency domain resources occupied by the control resource set CORESET according to the first indication information.
