[0027] This disclosure provides embodiments of a method for determining enable or disable, a communication device, a communication system, and a storage medium.

[0028] In a first aspect, embodiments of this disclosure propose a method for determining whether to enable or disable a terminal. The method includes: determining whether to enable a first characteristic of the terminal, wherein the first characteristic includes: determining first information based on relevant information of a first signal in the Physical Downlink Control Channel (PDCCH), wherein the first information is used to determine one or more first downlink control indications (DCIs), wherein the first DCI is a DCI that the terminal needs to detect in the PDCCH.

[0029] In the above embodiments, the terminal determines whether a first feature is enabled. When the first feature is enabled, the terminal can perform a first operation; when the first feature is disabled, the terminal can perform a second operation. The first feature may include: determining first information based on relevant information of a first signal in the PDCCH. This first information can be used to determine one or more first DCIs, where the first DCI is the DCI that the terminal needs to detect in the PDCCH. Therefore, this disclosure provides a method for enabling or disabling a first feature, allowing for flexible enabling or disabling at appropriate times. For example, when the terminal does not need the first information during blind DCI detection and the required number of blind detections is small, the terminal can perform fewer blind detections without the first information, achieving energy saving and consumption reduction. In this case, the terminal can disable the first feature and not determine the first information, thus preventing the terminal from additionally determining the first information when the number of blind detections is small. This avoids unnecessary steps for the terminal, reduces terminal complexity, saves terminal power consumption, and improves terminal efficiency.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, the first DCI is located in a first candidate resource, which is part or all of the resources occupied by the PDCCH;

[0033] In the above embodiments, it is explained what the first information and the related information of the first signal may include, so that the terminal can accurately determine the related information of the first signal, and then determine the first information based on the related information of the first signal, and determine the first DCI to be detected based on the first information. This makes the terminal's detection of DCI directional, avoids some invalid blind detection, reduces the number of blind detections (or detections), thereby reducing the complexity and energy consumption of the terminal and improving efficiency.

This gives the terminal directionality for DCI detection, avoids some invalid blind detections, reduces the number of blind detections (or detections), thereby reducing terminal complexity and energy consumption, and improving efficiency. However, in some embodiments, when the original PDCCH blind detection resource configuration is small, even if the terminal does not determine the first information, the total number of blind detections of DCIs by the terminal will still be small. In this case, if an additional pre-detection operation is introduced, it will lead to increased terminal complexity and affect detection efficiency.

[0106] Optionally, in some embodiments, when the network device configures the terminal to enable or disable the first feature, it can do so based on predefined protocol rules. Optionally, these predefined rules may include, for example, that if the network device determines to enable the first feature, it configures a second parameter to the terminal; if the network device determines to disable the first feature, it does not configure the second parameter to the terminal.

In other embodiments, the step of "terminal detecting the first DCI" can be classified as the process of terminal detecting DCI, while the step of "terminal determining the first information" is not classified as the process of terminal detecting DCI.

[0130] Optionally, in some embodiments, the enabling of this disclosure generally takes one of the following two forms: First, the network device is configured to enable or disable the first feature. Second, the terminal's enabling first feature is predefined, and the network device is configured to disable the terminal's first feature, eliminating the need to configure the terminal's enabling first feature again.

[0131] In summary, the terminal determines whether the first characteristic is enabled. When the first characteristic is enabled, the terminal can perform a first operation; when the first characteristic is disabled, the terminal can perform a second operation. The first characteristic may include: determining first information based on relevant information of the first signal in the PDCCH. This first information can be used to determine one or more first DCIs, where the first DCI is the DCI that the terminal needs to detect in the PDCCH. Therefore, this disclosure provides a method for enabling or deactivating the first characteristic, allowing for flexible enabling or deactivation at appropriate times. For example, when the terminal does not need the first information during blind DCI detection and the required number of blind detections is small, the terminal can perform fewer blind detections without the first information, achieving energy saving and consumption reduction. In this case, the terminal can deactivate the first characteristic and not determine the first information, thus preventing the terminal from additionally determining the first information when the number of blind detections is small. This avoids unnecessary steps for the terminal, reduces terminal complexity, saves terminal power consumption, and improves terminal efficiency. Furthermore, this disclosure also provides the operations required for the terminal and network device to perform when the first feature is enabled or disabled, thus improving the enabling mechanism of the first feature and enriching the comprehensiveness of the communication method.

[0161] Step 2302: The terminal sends an uplink control indicator (UCI) to the network device.

[0162] Optionally, the UCI can be used to indicate whether a first feature is enabled. Optionally, the terminal can use a first UCI format to indicate whether the first feature is enabled or disabled. For example, if the UCI format is the first UCI format, it indicates that the first feature is enabled; if the UCI format is not the first UCI format, it indicates that the first feature is disabled. Alternatively, if the UCI format is the first UCI format, it indicates that the first feature is disabled; if the UCI format is not the first UCI format, it indicates that the first feature is enabled. The first UCI format can be predefined by the protocol. Alternatively, the UCI can carry bit values. When the bit value carried by the UCI is a first value (e.g., 1), the first feature is enabled; when the bit value carried by the UCI is a second value (e.g., 0), the first feature is disabled.

When the first characteristic is enabled, the terminal can perform a first operation; when the first characteristic is disabled, the terminal can perform a second operation. The first characteristic may include: determining first information based on relevant information of the first signal in the PDCCH. This first information can be used to determine one or more first DCIs, where the first DCI is the DCI that the terminal needs to detect in the PDCCH. Therefore, this disclosure provides a method for enabling or deactivating the first characteristic, allowing for flexible enabling or deactivation at appropriate times. For example, when the terminal does not need the first information during blind DCI detection and the required number of blind detections is small, the terminal can perform fewer blind detections without the first information, achieving energy saving and consumption reduction. In this case, the terminal can deactivate the first characteristic and not determine the first information, thus preventing the terminal from additionally determining the first information when the number of blind detections is small. This avoids unnecessary steps for the terminal, reduces terminal complexity, saves terminal power consumption, and improves terminal efficiency. Furthermore, this disclosure also provides the operations required for the terminal and network device to perform when the first feature is enabled or disabled, thus improving the enabling mechanism of the first feature and enriching the comprehensiveness of the communication method.

[0168] The method for determining enable or disable involved in the embodiments of this disclosure may include at least one of steps 2301 to 2304. For example, steps 2301+2302 may be implemented as independent embodiments, steps 2304 may be implemented as independent embodiments, steps 2303+2304 may be implemented as independent embodiments, but are not limited thereto.

[0169] In some embodiments, the order of steps 2303 and 2304 can be interchanged or performed simultaneously.

[0288] The following is an exemplary description of the above method.

[0289] 1: Overview of NR PDCCH

[0290] In NR, to improve link performance through beamforming of the PDCCH, optimize the design of the PDCCH reference signal, simplify base station scheduling, and save power consumption of the base station and terminals, NR adopts terminal-specific PDCCH resources. The PDCCH monitoring range of a terminal is concentrated from the system bandwidth into a "control subband", namely the control resource set (CORESET).

[0291] NR introduces mini-slots and flexible channel structures to achieve low latency. The LTE PDCCH, which can only be transmitted in the first few symbols of a subframe, cannot meet the requirements of URLLC and low-latency eMBB services. Furthermore, LTE terminals need to monitor the PDCCH in every downlink subframe, resulting in high terminal power consumption. Therefore, NR PDCCH requires a time-domain flexible PDCCH to match the flexibility of the data channel, thereby achieving on-demand transmission. This flexibility is ultimately reflected in the design of the PDCCH search space set.

[0292] NR carrier bandwidth can reach over 100MHz, and TDM alone cannot effectively reuse PDCCH and PDSCH, resulting in a significant waste of frequency domain resources on both sides of the PDCCH. Therefore, 5G NR systems support FDM for both PDCCH and PDSCH. From a terminal's perspective, its PDCCH is confined to the Control Sub-Band, while it can simultaneously receive PDSCH outside the Control Sub-Band. The base station's ORESET configuration implements this scheduling. Multiplexing between the PDCCH of other terminals and the PDSCH of this terminal is more complex, requiring information on PDCCH resources occupied by other terminals and further resolution through rate matching and other methods.

[0293] 2: Brief Description of NR PDCCH Blind Testing

[0294] NR service channels employ a mechanism for multiple users and services to share the entire physical layer resources. The design must balance flexibility with efficiency; therefore, service allocation for a specific user can be dynamic in both time and frequency. This dynamic allocation of network resources in the time-frequency domain requires the DCI (Distributed Access Control) to inform the terminal. However, the location of the DCI is also dynamic, necessitating a mechanism to allocate it to each valid terminal. This effective mechanism is known as DCI "blind detection." Each time a terminal performs a PDCCH (Programmable Channel Control Center) check, it has a specific purpose, indicated by the RNTI (Reference Receiver Type Indicator). Within the same PDCCH, a terminal may need to check multiple DCIs, requiring a blind detection attempt for each RNTI. Therefore, blind detection is essentially a process of trying each possible unit using the RNTI.

[0295] The entire process from PDCCH blind detection to DCI can be divided into two parts: the terminal determining the necessary information and PDCCH channel decoding. From the terminal's perspective, the more RNTIs involved, the more PDCCH blind detections are required based on RNTI settings, and RNTI settings themselves are related to scheduling cases.

[0296] The PDCCH blind detection process may include the following steps: the terminal determines necessary information, which may include at least one of the following steps: the terminal obtains the RNTI, the terminal calculates the DCI Size, the terminal obtains candidate PDCCH resources (or Candidates resources, Candidates, etc.) for different ALs, and the terminal calculates the DCI blind detection start position. Optionally, the RNTI may be allocated to the terminal by the base station based on different scheduling cases. Optionally, the DCI Size may be the size of the DCI that the terminal wants to detect. In some embodiments, the terminal may calculate the DCI Size based on a reference DCI Size and an alignment DCI Size. Optionally, the reference DCI Size may be determined based on DCI Format 0_0 and the initial bandwidth part (BWP). Optionally, the candidate PDCCH resources may include, for example, a CORESET configuration and / or a search space (SS) configuration. Optionally, the aforementioned DCI blind detection start position can be calculated by the terminal based on CCE#0 in the Common Search Space (CSS) to determine the DCI blind detection start position corresponding to the CSS. Alternatively, the aforementioned DCI blind detection start position can be calculated by the terminal based on the HASH function of the Terminal Specific Search Space (USS) to determine the DCI blind detection start position corresponding to the USS. Optionally, after determining the necessary information, the terminal can perform channel decoding on the PDCCH. Optionally, the terminal can first demodulate the PDCCH channel code Polar code, for example, the terminal can demodulate the Polar code based on the DCI Size. Also, the terminal can perform Cyclic Redundancy Check (CRC) verification on the channel-decoded data, for example, the terminal can perform CRC verification on the channel-decoded data based on RNTI. If the verification is successful, the terminal considers that it has detected the required DCI. If the verification fails, the terminal selects a DCI with a different DCI Format and / or a different DCI Size for re-verification. If all DCIs in the current candidate PDCCH resources fail verification, the terminal proceeds to detect the next candidate PDCCH resource until the verification is successful. Optionally, if there are other DCI detection requirements, the terminal repeats the above process (such as the verification process) according to other DCI detection requirements. If all DCIs in the candidate PDCCH resources fail verification, it is determined that no DCI has been received, and the verification is abandoned.

[0297] In the current mechanism, the terminal receives DCI (Distributed Content Detection) through blind detection, which is a major reason for the high complexity and energy consumption of the terminal implementation. In 6G PDCCH design, reducing the number of blind DCI detections is an important research direction, and the number of blind DCI detections is one of the main evaluation indicators. One evolutionary approach is to have the terminal determine the prior information for PDCCH blind detection, enabling it to avoid some invalid blind detections during the process, thereby reducing the number of blind detections. However, determining the prior information for blind detection requires the terminal to perform additional operations, such as determining the time-frequency resource location of the blind DMRS (Distributed DMRS) or different sequences of the blind DMRS. This requires the terminal to have additional blind detection capabilities to ensure that it can complete the corresponding detection work and obtain the prior information between formal blind DCI detections.

[0298] Question 1: Enabling / De-enabling the terminal to acquire PDCCH blind detection prior information (i.e., the first information in the embodiments of Figures 2A-2C above).

[0299] When the original PDCCH blind detection resource configuration is limited, performing additional prior information acquisition procedures will increase complexity. Therefore, it is necessary to enable / disable the pre-detection DMRS (i.e., determining the first information based on the relevant information of the first signal in the embodiments of Figures 2A-2C above). The indication methods for enabling / disabling the pre-detection DMRS include dynamic, semi-static, and semi-persistent (enabling upon receiving signaling, then disabling upon receiving signaling), and the decision-makers include the base station, the terminal, and the base station decision within the terminal's reporting range.

[0300] Question 2: What is the behavior of the terminal device after enabling / disabling the PDCCH blind detection prior information?

[0301] After enabling the preflight DMRS, the terminal can attempt to acquire PDCCH blind detection prior information at the most recent PDCCH listening time, or it can start attempting to acquire PDCCH blind detection prior information after a certain delay. After disabling the preflight DMRS, the terminal can immediately stop attempting to acquire PDCCH blind detection prior information at the most recent PDCCH listening time (i.e., the first PDCCH listening time in the embodiments of Figures 2A-2C above), or it can stop acquiring PDCCH blind detection prior information after a certain delay.

[0302] Optional Example 1

[0303] In a network, a terminal determines the DCI sent by a network device through blind detection. Before blindly detecting the DCI, the terminal can determine the PDCCH blind detection prior information through the pre-detection DMRS. In other words, during the terminal's blind DCI detection process, the PDCCH blind detection prior information can be determined through the pre-detection DMRS. The PDCCH blind detection prior information includes at least one of a first prior information and a second prior information. Based on the base station's decision to enable / disable the terminal pre-detection DMRS, optionally, the first prior information may be, for example, information related to the first candidate resource in the first information of the embodiment in Figure 2A, such as: first AL value, second AL value, first AL set, resource type of the first candidate resource, etc. The second prior information may be, for example, information related to the first DCI in the first information of the embodiment in Figure 2A, such as: DCI format of the first DCI, DCI size of the first DCI, RNTI of the first DCI, etc. Specific methods include at least one of the following:

[0304] Optional Example 1:

[0305] The base station configures to enable / disable preflight DMRS via a first signaling instruction. The first signaling instruction includes at least one of RRC signaling, MAC CE, and DCI. Preferably, it is RRC. Specifically, the first signaling instruction configures / indicates a first parameter, which is used to indicate whether to enable / disable preflight DMRS.

[0306] Example 1: The first parameter is configured by RRC signaling. The first parameter contains an indicator bit. If the bit value is the first value (eg1), it indicates that the preflight DMRS is enabled; if the bit value is the second value (eg0), it indicates that the preflight DMRS is disabled.

[0307] Optional Example 2:

[0308] The protocol predefines a first rule to enable / disable the preflight DMRS. Specifically, the base station can configure a first relationship parameter for the terminal, which is used to configure the relationship information of the preflight DMRS. The first relationship parameter also includes, but is not limited to, other necessary configuration information for the preflight DMRS.

[0309] If the first relation parameter is omitted, the preflight DMRS is disabled.

[0310] Optionally, if the first relational parameter exists, the preflight DMRS is enabled.

[0311] Optional Example 3:

[0312] The base station configures the Search Space / CORESET enabled by pre-detection DMRS via a second signaling. The second signaling includes at least one of RRC signaling, MAC CE, and DCI. Preferably, it is RRC. Specifically, the second signaling configures / indicates a second parameter, which is used to indicate whether the corresponding Search Space / CORESET (i.e., the first resource location in the embodiments of Figures 2A-2C above) is enabled or disabled.

[0313] Example 1: The second parameter is configured by RRC signaling. If the second parameter is configured as Search Space ID, then the terminal will enable pre-detection DMRS when listening to the configured Search Space ID.

[0314] Example 2: The second parameter is configured by RRC signaling. If the second parameter is configured with CORESET ID, then the terminal will enable pre-detection DMRS when listening to the configured CORESET ID.

[0315] Example 3: The second parameter is configured by RRC signaling. The second parameter configures the CORESET ID and Search Space ID. Then, the terminal enables pre-detection DMRS at the listening time determined by the configured CORESET ID and Search Space ID.

The PDCCH blind detection prior information includes at least one of a first prior information and a second prior information.

[0318] The terminal device reports first auxiliary information (i.e., the second information in the embodiments of Figures 2A-2C above), and the base station enables / disables the pre-detection DMRS based on the first auxiliary information reported by the terminal device. The method for determining the first auxiliary information includes at least one of the following:

[0319] Optional Example 1:

[0320] The first auxiliary information is time information, that is, the time information when the terminal reports the pre-detection DMRS. The base station enables / disables the pre-detection DMRS within the time range (i.e., the first time period in the embodiments of Figures 2A-2C above).

[0321] Optional Example 2:

[0322] The first auxiliary information is the searchspace ID (i.e., the first resource location in the embodiments of Figures 2A-2C above), which is the searchspace ID associated with the pre-detection DMRS reported by the terminal. The base station enables / disables the pre-detection DMRS within the range of the reported searchspace ID.

[0323] Optional Example 3:

[0324] The first auxiliary information is the CORESET ID (i.e., the first resource location in the embodiments of Figures 2A-2C above), which is the CORESET ID associated with the pre-detection DMRS reported by the terminal. The base station enables / disables the pre-detection DMRS within the range of the reported CORESET ID.

[0325] Optional Example 3

[0326] In a network, a terminal determines the DCI sent by a network device through blind detection. Before blindly detecting the DCI, the terminal can determine the PDCCH blind detection prior information; in other words, during the blind detection of the DCI, the terminal can determine the PDCCH blind detection prior information. The PDCCH blind detection prior information includes at least one of a first prior information and a second prior information.

[0327] The terminal device-based decision-making for enabling / disabling terminal pre-detection DMRS includes at least one of the following methods:

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.
