[0110] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0111] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.
[0112] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0113] Optionally, in both LTE and NR, information used for downlink control (e.g., downlink control information (DCI)) can be carried through the Physical Downlink Control Channel (PDCCH). However, PDCCH resources are limited, so it is advisable to use a data channel (a channel capable of carrying data information) to carry this information. The data channel can be, for example, a semi-persistent scheduling (SPS) channel, or a Physical Downlink Shared Channel (PDSCH). In related technologies, when using a data channel to carry downlink control information, the channel reliability is low, thus affecting the transmission reliability of the information carried by the channel.
[0114] Figure 2 is an interactive schematic diagram of a communication control method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a communication control method, which can be used in a communication system 100. The method includes:
[0115] Step S2101: The network device determines the first information of the data channel.
[0116] Optionally, in some embodiments, the data channel includes at least one of the following: a first type of channel, a second type of channel, and a third type of channel. The first type of channel is dynamically scheduled using third information, which is used for downlink control; the second type of channel is configured semi-statically; and the third type of channel is pre-configured semi-statically and then dynamically activated. Therefore, various possible types of data channels can be used to carry the second information, and the reliability of the data channel can be improved when using any possible type of data channel to carry the second information.
[0117] Optionally, in some embodiments, the third information can be used for downlink control. The third information can be, for example, downlink control information (e.g., legacy DCI).
[0118] Optionally, in some embodiments, the data channel may include a first type of channel, which is dynamically scheduled through third information.
[0119] Optionally, in some embodiments, the first type of channel may refer to a data channel dynamically scheduled via downlink control information. For example, the first type of channel is a PDSCH scheduled via legacy DCI.
[0120] Optionally, in some embodiments, the data channel may include a second type of channel, which is configured semi-statically.
[0121] Optionally, in some embodiments, the second type of channel may refer to a semi-statically configured data channel. For example, the second type of channel is an SPS channel configured via Radio Resource Control (RRC).
[0122] Optionally, in some embodiments, the data channel may include a third type of channel, which is pre-configured semi-statically and activated dynamically.
[0123] Optionally, in some embodiments, the third type of channel may refer to a semi-statically pre-configured and dynamically activated data channel. For example, the third type of channel is an SPS channel pre-configured via RRC and activated by legacy DCI.
[0124] Optionally, in some embodiments, the data channel includes at least one of the following: a Physical Downlink Shared Channel (PDSCH); and a Semi-Persistent Scheduling (SPS) channel. Therefore, various possible types of data channels can be used to carry the second information, and the reliability of the data channel can be improved when using any possible type of data channel to carry the second information.
[0125] Optionally, in some embodiments, the data channel may include at least two of the first type of channel, the second type of channel, and the third type of channel described above. Specifically, it can be configured in a personalized manner according to the needs of the actual communication application, and there is no limitation thereto.
[0126] Optionally, in some embodiments, the data channel can be at least one of the above-mentioned PDSCH and SPS channels, and can be customized according to the needs of actual communication applications, without limitation.
[0127] Optionally, in some embodiments, the second and third types of channels described above can both be, for example, SPS channels. That is, an SPS channel can be an optional example of a semi-statically configured data channel. Alternatively, an SPS channel can be an optional example of a semi-statically pre-configured and dynamically activated data channel, without limitation.
[0128] Optionally, in some embodiments, the first information is used to describe the data channel. The first information may be some parameters related to the data channel. The first information can be used to analyze whether the data channel meets the conditions, and if the data channel meets the conditions, second information can be sent based on the data channel. A description of the second information is provided below.
[0129] Optionally, in some embodiments, the first information includes at least one of the following: the demodulation reference signal (DMRS) mapping type of the data channel, the modulation and coding scheme (MCS) of the data channel, the frequency domain resource allocation method of the data channel, the DMRS configuration type of the data channel, the priority of the data channel, the port number corresponding to the DMRS of the data channel, and the number of ports configured for the data channel. This allows for constraints on the data channel in various dimensions, effectively adapting to personalized communication scenarios. Furthermore, when using the data channel to carry information for downlink control, it can maximize channel reliability, thereby helping to improve the transmission reliability of the information carried by the channel.
[0130] Optionally, in some embodiments, the first information of the data channel may be pre-configured or predefined by the protocol. For example, when determining the first information of the data channel, it may be by obtaining the pre-configured first information or by determining the first information based on a predefined protocol, without limitation.
[0131] In step S2102, the network device determines that the data channel meets the conditions based on the first information.
[0132] Optionally, in some embodiments, after determining the first information of the data channel, the network device may refer to the first information to determine whether the data channel meets the conditions, and if it is determined that the data channel meets the conditions, trigger, configure, or enable the transmission of the second information through the data channel.
[0133] The second information is used for downlink control. That is, the second information is used for downlink control. The second information can also be called downlink control information. For example, the second information can be, for instance, new downlink control information (new-DCI).
[0134] Optionally, in some embodiments, the condition may refer to a threshold condition that ensures the data channel has good reliability when using it to carry downlink control information. The condition may be predefined by the protocol. For example, when the data channel meets the condition, the data channel can be configured, triggered, or enabled to carry new-DCI.
[0135] Optionally, in some embodiments, the network device may refer to at least one of the first information described above to ensure that the data channel meets the conditions, and send the second information through the data channel.
[0136] Optionally, in some other embodiments, the network device may refer to at least one of the first information mentioned above to determine whether the data channel meets the conditions. If it is determined that the data channel does not meet the conditions, step S2103 may not be executed, or some constraints may be applied to the first information of the data channel to make the data channel meet the conditions. After the data channel meets the conditions, the transmission of the second information through the data channel is triggered. Thus, it is possible to comprehensively ensure that the data channel meets the conditions, thereby ensuring the reliability of the data channel.
[0137] Optionally, in some embodiments, the first information may include: the DMRS mapping type of the data channel. Then, based on the DMRS mapping type of the data channel, it can be determined whether the data channel meets the conditions. In some embodiments, when the DMRS mapping type of the data channel is a first mapping type, it is determined that the data channel meets the conditions; wherein, the first mapping type includes: the time domain unit where the DMRS mapping resource of the data channel is located is the same as the time domain unit of the first resource and the time domain unit of the second resource, and the frequency domain unit where the DMRS mapping resource of the data channel is located includes: the frequency domain unit of the first resource and the frequency domain unit of the second resource, the time domain unit of the first resource is the same as the time domain unit of the second resource, and the frequency domain unit of the first resource is different from the frequency domain unit of the second resource, wherein the first resource is used for the second information, and the second resource is not used for the second information. Therefore, the frequency domain resource utilization of the data channel can be effectively improved, thereby effectively improving the reliability of the data channel and achieving improved transmission reliability of the information carried by the channel.
[0138] Optionally, in some embodiments, the first resource refers to a resource used for the second information, and the second resource refers to a resource not used for the second information.
[0139] Optionally, in some embodiments, the first mapping type described above may also be referred to as wideband mapping. In wideband mapping, DMRS is mapped to resources that are candidates for new-DCI (i.e., resources used for new-DCI, which is an optional example of the first resource), while DMRS is also mapped to resources that are not candidates for new-DCI (i.e., resources not used for new-DCI, which is an optional example of the second resource).
[0140] In other words, if the data channel meets the conditions based on the "DMRS mapping type of the data channel" in the first information of the data channel, then the data channel can be determined to meet the conditions if the DMRS mapping type of the data channel is the first mapping type.
[0141] For example, resources can be pre-allocated to the data channel (e.g., configuration or protocol predefined). These resources can include: resources used as candidates for carrying second information (an optional example of the first resource), and resources not used as candidates for carrying second information (an optional example of the second resource). The data channel is determined to meet the condition when its DMRS mapping is "used as a candidate for carrying second information" in the data channel's resources, and when its DMRS mapping is "not used as a candidate for carrying second information" in the data channel's resources.
[0142] In other words, in the first mapping type, the time domain unit where the DMRS mapping resource of the data channel is located is the same as the time domain unit of the first resource and the time domain unit of the second resource, and the frequency domain unit where the DMRS mapping resource of the data channel is located includes: the frequency domain unit of the first resource and the frequency domain unit of the second resource, the time domain unit of the first resource is the same as the time domain unit of the second resource, and the frequency domain unit of the first resource is different from the frequency domain unit of the second resource.
[0143] As shown in Figures 3A and 3B, Figure 3A is a schematic diagram of one type of the first mapping in an embodiment of this disclosure. Figure 3B is a schematic diagram of another type of the first mapping in an embodiment of this disclosure. In Figure 3A, the new-DCI is mapped to the second time-domain symbol (an optional example of a time-domain unit) of the PDSCH, i.e., time-domain symbol #3, and the new-DCI candidate resource (an optional example of the first resource) is a dark gray time-frequency block. DMRS is mapped to the entire PDSCH frequency-domain resource corresponding to time-domain symbol #3. In Figure 3B, the new-DCI is mapped to the second time-domain symbol of the PDSCH, i.e., time-domain symbol #3, and the new-DCI candidate resource is a dark gray time-frequency block. DMRS is mapped to the entire PDSCH frequency-domain resource corresponding to time-domain symbol #3. The resources on the entire time-domain symbol #3 other than the "new-DCI candidate resource" are the "non-new-DCI candidate resource" (an optional example of the second resource).
[0144] Optionally, in some embodiments, the data channel can be determined to meet the conditions even if the DMRS mapping type of the data channel is a second mapping type. The second mapping type includes: the time domain unit where the DMRS mapping resource of the data channel is located is the same as the time domain unit of the first resource, and the frequency domain unit where the DMRS mapping resource of the data channel is located is the same as the frequency domain unit of the first resource, wherein the first resource is used for the second information. Therefore, while effectively ensuring and improving the reliability of the data channel, it also effectively improves the flexibility of communication control, making it effectively applicable to personalized communication scenarios.
[0145] In other words, if the data channel meets the conditions based on the "DMRS mapping type of the data channel" in the first information of the data channel, then the data channel can be determined to meet the conditions if the DMRS mapping type of the data channel is the second mapping type.
[0146] For example, resources can be pre-allocated to the data channel (e.g., configuration or protocol predefined). These resources can include: resources used as candidates for carrying second information (an optional example of the first resource), or resources not used as candidates for carrying second information (an optional example of the second resource). When the DMRS mapping of the data channel is "resources used as candidates for carrying second information" in the data channel's resources, it is determined that the data channel meets the condition.
[0147] In other words, in the second mapping type, the time domain unit where the DMRS mapping resource of the data channel is located is the same as the time domain unit of the first resource, and the frequency domain unit where the DMRS mapping resource of the data channel is located is the same as the frequency domain unit of the first resource.
[0148] As shown in Figures 3C and 3D, Figure 3C is a schematic diagram of one type of the second mapping in an embodiment of this disclosure. Figure 3D is a schematic diagram of another type of the second mapping in an embodiment of this disclosure. In Figure 3C, the new-DCI is mapped to the second time-domain symbol (an optional example of a time-domain cell) of the PDSCH, i.e., time-domain symbol #3, and the new-DCI candidate resource (an optional example of a first resource) is a dark gray time-frequency block. The DMRS is mapped to the time-frequency block of the "new-DCI candidate resource" in time-domain symbol #3. In Figure 3D, the new-DCI is mapped to the second time-domain symbol of the PDSCH, i.e., time-domain symbol #3, and the new-DCI candidate resource is a dark gray time-frequency block. The DMRS is mapped to the time-frequency block of the "new-DCI candidate resource" in time-domain symbol #3.
[0149] Optionally, in some embodiments, the first information may include the value of the modulation and coding scheme (MCS) of the data channel. This "value" may refer to the index value of the MCS. The data channel can then be guaranteed to meet certain conditions based on the value of its MCS. In some embodiments, the data channel can be determined to meet certain conditions if its MCS value is a first value, wherein the first and second values are agreed upon by the protocol. Therefore, while effectively ensuring and improving the reliability of the data channel, it also effectively improves the flexibility of communication control, making it suitable for personalized communication scenarios.
[0150] Optionally, in some embodiments, the first value may also be referred to as n0, and the first value may be an integer predefined by the protocol.
[0151] Optionally, in some embodiments, the first value is 0. That is, the data channel can be determined to meet the condition when the Modulation and Coding Scheme (MCS) of the data channel is 0. Therefore, it is possible to use lower modulation schemes and coding strategies, providing a more stable communication connection in environments with poor signal quality, reducing the error rate in data transmission, thereby effectively improving communication stability, ensuring data transmission reliability, and ultimately supporting improved channel reliability. It also possesses good compatibility and versatility, adapting to various communication devices and networks.
[0152] Optionally, in some embodiments, the data channel can be determined to meet the condition if the MCS value of the data channel is less than or equal to a second value. This allows for the use of lower modulation schemes and coding strategies, providing more stable communication connections in environments with poor signal quality, reducing the error rate in data transmission, thereby effectively improving communication stability, ensuring data transmission reliability, and ultimately supporting improved channel reliability. Furthermore, it enhances the flexibility of communication control, making it effectively applicable to personalized communication scenarios.
[0153] Optionally, in some embodiments, the first information of the data channel may include: the frequency domain resource allocation method of the data channel. Based on the frequency domain resource allocation method of the data channel, it can be ensured that the data channel meets the conditions. In some embodiments, the frequency domain resource allocation method of the data channel can be a first type of allocation method to determine that the data channel meets the conditions; wherein, the first type of allocation method is used to allocate continuous frequency domain resources. This effectively reduces channel interference, thereby increasing system capacity and supporting improved channel performance, thus improving channel reliability.
[0154] Optionally, in some embodiments, the first type of allocation method may also be referred to as type 1. Wherein, type 1 is continuous frequency domain resource allocation.
[0155] In other words, when the frequency domain resource allocation method of the data channel is type 1, the data channel is determined to meet the conditions, thereby ensuring that the data channel has good reliability when transmitting the second information, so as to support the improvement of the reliability of the second information transmission.
[0156] Optionally, in some embodiments, when the frequency domain resource allocation method of the data channel is the second type of allocation method, it is determined that the data channel meets the conditions; wherein, the second type of allocation method is used to allocate non-contiguous frequency domain resources. This effectively improves resource utilization, enhances communication quality, optimizes resource usage efficiency, and thus ensures improved channel reliability.
[0157] Optionally, in some embodiments, the second type of allocation method may also be referred to as type 0. Here, type 0 is a non-contiguous resource allocation.
[0158] In other words, when the frequency domain resource allocation method of the data channel is type 0, the data channel is determined to meet the conditions, thereby ensuring that the data channel has good reliability when transmitting the second information, so as to support the improvement of the reliability of the second information transmission.
[0159] Optionally, in some embodiments, the information of the data channel may include the DMRS configuration type of the data channel. Based on the DMRS configuration type of the data channel, it can be ensured that the data channel meets the conditions. In some embodiments, it can be determined that the data channel meets the conditions if the DMRS configuration type of the data channel is DMRS configuration type 1. This enables improved channel estimation performance, thereby ensuring improved channel reliability.
[0160] Optionally, in some embodiments, when the DMRS configuration type of the data channel is DMRS configuration type 1, the frequency domain density is high, which can support up to 8 ports, and each port can occupy 3 resource elements (REs).
[0161] In other words, when the DMRS configuration type of the data channel is DMRS configuration type 1, it is determined that the data channel meets the conditions. At this time, the channel estimation performance of the data channel is good. When the data channel is used to carry the second information, it can ensure that the data channel has good reliability, so as to support the improvement of the reliability of the second information transmission.
[0162] Optionally, in some embodiments, the DMRS configuration type of the data channel is DMRS configuration type 2, determining that the data channel meets the conditions. This enables improved spectral efficiency and channel immunity, thereby ensuring enhanced channel reliability.
[0163] Optionally, in some embodiments, when the DMRS configuration type of the data channel is DMRS configuration type 2, the frequency domain density is low, supporting up to 12 ports, with each port occupying 2 REs, and also achieving low overhead.
[0164] In other words, when the DMRS configuration type of the data channel is DMRS configuration type 2, and the data channel meets the conditions, the improved spectral efficiency and anti-interference capability of the channel ensure that the data channel has good reliability when carrying the second information, thus supporting the improvement of the reliability of the second information transmission.
[0165] Optionally, in some embodiments, the frequency domain density of DMRS configuration type 1 is higher than that of DMRS configuration type 2; the maximum number of ports supported by DMRS configuration type 1 is less than the maximum number of ports supported by DMRS configuration type 2; and the number of resource elements (REs) occupied by each port of DMRS configuration type 1 is greater than the number of REs occupied by each port of DMRS configuration type 2.
[0166] Optionally, in some embodiments, the first information may include the priority of the data channel. Based on the priority of the data channel, it can be ensured that the data channel meets the conditions. In some embodiments, the priority of the data channel is higher than the first priority, determining that the data channel meets the conditions. This ensures that the channel can preferentially utilize network bandwidth, improving channel transmission efficiency and thus enhancing channel reliability.
[0167] Optionally, in some embodiments, the priority can include two optional elements: high priority and low priority. The first priority can refer to "low priority," meaning that if the data channel's priority is higher than "low priority," i.e., the data channel's priority is "high priority," then the data channel is determined to meet the condition. In this case, since the channel can preferentially utilize network bandwidth and has better channel transmission efficiency, when using the data channel to carry the second information, it can ensure that the data channel has good reliability, thereby supporting improved reliability of the second information transmission.
[0168] Optionally, in some embodiments, the priority may include several levels: 1, 2, 3, 4, ..., 8 (this is just an example), where a larger value indicates a higher priority. The first priority may be, for example, "4", then if the priority of the data channel is higher than "4", the data channel is determined to meet the condition.
[0169] Optionally, in some embodiments, the first information may include the port number corresponding to the DMRS of the data channel. In some embodiments, if the port number corresponding to the DMRS of the data channel is a third value, it is determined that the data channel meets the condition, where the third value is agreed upon by the protocol. This effectively reduces channel interference, improves the signal-to-noise ratio, and enhances demodulation performance. When the data channel is used to carry the second information, it ensures that the data channel has good reliability, thereby supporting improved reliability of the second information transmission.
[0170] The third value mentioned above can be an integer predefined by the protocol. The third value can be represented as m0.
[0171] In other words, when the data channel can be configured with the DMRS of port m0, the data channel can be configured, triggered, and enabled to transmit second information.
[0172] Optionally, in some embodiments, the first information may include the number of ports configured for the data channel. If the number of ports configured for the data channel is less than or equal to a fourth value, the data channel is determined to meet the condition, where the fourth value is agreed upon by the protocol. This reduces channel collisions, thereby reducing interference, improving communication stability, and increasing channel transmission efficiency. Consequently, when using the data channel to carry the second information, it ensures that the data channel has good reliability, thus supporting improved reliability of the second information transmission.
[0173] Optionally, in some embodiments, the fourth value described above can be a predefined integer in the protocol. The fourth value can be represented as n.
[0174] In other words, the number of ports that can be configured for the data channel can be predefined by the protocol and does not exceed n (less than or equal to n), where n is an integer defined by the protocol.
[0175] In step S2103, the network device sends the second information through the data channel.
[0176] Optionally, in some embodiments, after determining that the data channel meets the conditions using at least one of the above methods, the network device may configure, trigger, or enable the transmission of second information through the data channel.
[0177] Optionally, in some embodiments, after the network device determines that the data channel meets the conditions using at least one of the above methods, it can configure the data channel accordingly so that the data channel can carry the second information, and then send the second information through the data channel.
[0178] Optionally, in some embodiments, after the network device determines that the data channel meets the conditions using at least one of the above methods, it may send second information through the data channel in response to the triggering of a triggering command.
[0179] Optionally, in some embodiments, after the network device determines that the data channel meets the conditions using at least one of the above methods, it can enable the function of the data channel to carry the second information, thereby enabling the second information to be sent through the data channel.
[0180] The communication control method disclosed in this embodiment may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as a standalone embodiment, step S2102 may be implemented as a standalone embodiment, and so on, but is not limited thereto. Steps S2101+S2102 may be implemented as standalone embodiments, and steps S2101+S2102+S2103 may be implemented as standalone embodiments, but is not limited thereto.
[0181] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0182] In this embodiment, by using data channels to carry downlink control information (e.g., new DCI), the terminal can avoid blind detection, thereby reducing the number of blind detections. While maintaining the existing amount of downlink control information in the network, the number of candidate positions for traditional downlink control information carried in the Physical Downlink Control Channel (PDCCH) can be reduced, further reducing the number of PDCCH blind detections. Furthermore, with the number of downlink control information items in the network remaining constant, the network side can reduce the configuration of traditional downlink control information carried in the PDCCH, effectively reducing the blocking probability of traditional downlink control information and helping to improve system throughput. It also provides more flexible resource locations for downlink control information transmission, enhancing scheduling flexibility. Moreover, since data channels can be configured with more time-frequency resources, larger downlink control information payloads (DCI payloads) can be allowed, facilitating the expansion of the functions supported by downlink control information. Based on the above, when using data channels to carry downlink control information, the channel can be ensured to have better reliability, supporting improved reliability of downlink control information transmission.

[0287] The DMRS mapping type of the data channel is wide band mapping, which means that DMRS is mapped on resources that are new-DCI candidates, and at the same time, DMRS is also mapped on resources that are not new-DCI candidates.
[0288] The MCS of the data channel is n0, where n0 is an integer defined by the protocol. Preferably, n0 = 0.

[0292] The DMRS configuration type for the data channel can be DMRS configuration type 1 (high frequency domain density, supporting up to 8 ports, with each port occupying 3 REs).

[0297] In a network, new-DCI can be mapped onto a data channel. New-DCI is control information defined by a protocol and can be carried by the data channel. A data channel refers to a channel capable of carrying data information, and can include, but is not limited to, at least one of the following: data channels dynamically scheduled via control information (e.g., PDSCH scheduled via legacy DCI), semi-statically configured data channels (e.g., SPS configured via RRC), and semi-statically pre-configured data channels dynamically activated (e.g., SPS pre-configured via RRC and activated by legacy DCI).
[0298] The protocol predefines that, when certain conditions are met, the data channel can be configured, triggered, or enabled to carry new-DCI. The methods for meeting these conditions include at least one of the following:
[0299] Optionally, in some embodiments of this disclosure, the protocol predefines that the DMRS mapping type of the data channel is a first type mapping (an optional example of the first mapping type).

[0303] Optionally, in some embodiments of this disclosure, the protocol predefines that the frequency domain resource allocation method for the data channel can only be type 1 (an optional example of the first type of allocation method). Type 1 is continuous frequency domain resource allocation.
[0304] Optionally, in some embodiments of this disclosure, the protocol predefines that the frequency domain resource allocation method for the data channel can only be type 0 (an optional example of the second type allocation method). Type 0 is a non-contiguous resource allocation.
[0305] Optionally, in some embodiments of this disclosure, the protocol is predefined, and the DMRS configuration type of the data channel can be DMRS configuration type 1 (high frequency domain density, supports up to 8 ports, each port occupies 3 REs, high overhead).

[0310] The above method has the following advantages: low code rate, wide-band DMRS, frequency domain discreteness, high-overhead DMRS, etc., can all ensure the reliability of the data channel as much as possible, thereby ensuring the reliability of new-DCI.
[0311] In this embodiment of the disclosure, the configuration of the data channel used to carry new-DCI can be implemented based on predefined rules, including but not limited to: DMRS mapping type, MCS, frequency domain resource allocation method, DMRS configuration type, data channel priority, port, etc.

[0313] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0314] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
