Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] Satellite communication is considered an important aspect of the future development of wireless communication technology due to its wide coverage.

[0003] However, the low power of satellite payloads and the long communication path of satellite communication can lead to poor communication link quality in some cases. For some important channels, such as the Physical Downlink Control Channel (PDCCH), if the poor quality of the communication link affects the terminal's detection of the information carried on it, it will be detrimental to normal communication. Summary of the Invention

[0004] This application provides a communication method aimed at solving the problem of poor communication link quality in satellite communication hindering normal communication. The disclosed technical solution is as follows:

[0005] The first aspect of this application provides a communication method, which can be executed by a terminal device, or by a component (such as a circuit, chip, or chip system) configured in the terminal device, or by a logic module or software capable of implementing all or part of the functions of the terminal device. This application does not limit this. The following description uses a terminal device as an example. The method includes: acquiring a synchronization signal and a Physical Broadcast Channel Block (SSB), wherein the SSB includes a first SSB and / or a second SSB, the first SSB is associated with a first time slot, the second SSB is associated with a second time slot, and the first and second time slots contain monitoring opportunities for detecting a first channel; using the monitoring opportunity in a third time slot as the detection opportunity for the initial transmission of the first channel, and using the monitoring opportunity in a fourth time slot as the detection opportunity for the repeated transmission of the first channel, wherein the third time slot is determined based on the first time slot, and the fourth time slot is determined based on the second time slot or the third time slot.

[0006] The communication method provided in the first aspect, because it obtains the SSB associated time slot, can obtain the detection timing of the initial transmission of the first channel and the detection timing of the repeated transmission of the first channel based on the SSB associated time slot. This lays the foundation for the terminal device to detect the initial transmission and repeated transmission of the first channel. The terminal device's detection of the initial transmission and repeated transmission of the first channel can overcome the problem that the terminal device cannot correctly detect the first channel due to poor communication link quality, thereby increasing the possibility of correctly detecting the first channel and thus helping to ensure normal communication.

[0007] In some implementations, the third time slot is the first time slot, or the third time slot is the next time slot after the first time slot. This method of determining the third time slot is beneficial for compatibility with existing protocols.

[0008] In some implementations, the fourth time slot is the second time slot, or the fourth time slot is the U-th time slot after the second time slot, where U is an integer greater than or equal to 1. Determining the fourth time slot based on U, rather than being limited to the second time slot or the next time slot after the second time slot, allows for greater flexibility in the selection of the fourth time slot.

[0009] In some implementations, the fourth time slot is the Vth time slot after the third time slot, where V is an integer greater than or equal to 1, which makes the selection of the fourth time slot more flexible.

[0010] In some implementations, the values ​​of U and V are determined by protocol or configured by network devices.

[0011] In some implementations, the monitoring timing in the third time slot includes either the first monitoring timing in the third time slot or the second monitoring timing in the third time slot.

[0012] In some implementations, the monitoring timing in the fourth time slot includes either the first monitoring timing in the fourth time slot or the second monitoring timing in the fourth time slot.

[0013] In some implementations, the monitoring timing in the third time slot is used as the detection timing for the initial transmission of the first channel, and the monitoring timing in the fourth time slot is used as the detection timing for the repeated transmission of the first channel. This includes: determining a monitoring timing in the third time slot as the detection timing for the initial transmission of the first channel, and determining a monitoring timing in the fourth time slot as the detection timing for the repeated transmission of the first channel, according to the protocol agreement or network device configuration.

[0014] In some implementations, before obtaining the SSB, the method further includes: sending first information to the network device. This first information instructs the terminal device to support repeated transmission of the first channel, or requests repeated transmission of the first channel by the terminal device. The terminal device informing the network device of its support for repeated transmission of the first channel helps the network device determine whether to repeat the first channel based on the terminal's capabilities, thereby increasing the likelihood of normal communication. The terminal device's request to repeat the first channel, for example, when the communication link quality is poor, allows the network to selectively repeat the first channel, increasing the likelihood that the terminal device correctly detects the first channel even with a poor communication link, thus improving the probability of normal communication.

[0015] In some implementations, before obtaining the SSB, the process includes receiving first configuration information from the network device, which indicates that the first channel should be retransmitted. Because the network device can obtain the capabilities or requests of each terminal device, configuring the retransmission of the first channel by the network device allows it to decide whether to retransmit the first channel based on the situation of each terminal, thus satisfying the retransmission needs of most terminal devices.

[0016] In some implementations, acquiring the SSB includes acquiring a first SSB and / or a second SSB that meets the quality requirements. Selecting an SSB that meets the quality requirements helps to further ensure normal communication.

[0017] In some implementations, the first channel includes: a target physical downlink control channel (PDCCH), which is used to schedule the physical downlink shared channel (PDSCH) that carries system information block SIB1.

[0018] Some implementations also include counting the candidate first channels in the third and fourth time slots into the blind detection count. Including the candidate first channels in both the initial transmission time slot and the retransmission time slot into the blind detection count helps to further increase the probability of correctly detecting the first channel, thereby further increasing the probability of normal communication.

[0019] In some implementations, the following are also included: the candidate first channel in the third time slot is counted in the blind detection count; the candidate first channel in the fourth time slot is not counted in the blind detection count, so as to save blind detection resources.

[0020] Some implementations also include: candidate first channels in the third time slot are not counted in the blind detection count; candidate first channels in the fourth time slot are counted in the blind detection count, which can save blind detection resources while increasing the probability of correctly detecting the first channel.

[0021] In some implementations, when the number of blind detections exceeds the detection capability of the terminal device, the terminal device determines whether to detect the candidate first channel based on the priority of the candidate first channel. The priority of the candidate first channel is pre-agreed through a protocol or configured by the network device to ensure that blind detection is performed within the capability of the terminal device, thereby saving terminal device resources and improving the terminal device's battery life.

[0022] The second aspect of this application provides a communication method that can be executed by a network device, or by a component (such as a circuit, chip, or chip system) configured in the network device, or by a logic module or software capable of implementing all or part of the functions of the network device. This application does not limit this. The following description uses a network device as an example. The method includes: transmitting a synchronization signal and a Physical Broadcast Channel Block (SSB), wherein the SSB includes a first SSB and / or a second SSB, the first SSB is associated with a first time slot, the second SSB is associated with a second time slot, and the first and second time slots contain monitoring opportunities for detecting the first channel; using the monitoring opportunity in a third time slot as the opportunity for the initial transmission of the first channel, and using the monitoring opportunity in a fourth time slot as the opportunity for repeated transmission of the first channel, wherein the third time slot is determined based on the first time slot, and the fourth time slot is determined based on the second or third time slot. Repeated transmission of the first channel is beneficial for ensuring normal communication; therefore, this method can lay the foundation for ensuring normal communication.

[0023] In some implementations, the third time slot is the first time slot, or the third time slot is the next time slot after the first time slot.

[0024] In some implementations, the fourth time slot is the second time slot, or the fourth time slot is the U-th time slot after the second time slot, where U is an integer greater than or equal to 1.

[0025] In some implementations, the fourth time slot is the Vth time slot after the third time slot, where V is an integer greater than or equal to 1.

[0026] In some implementations, the values ​​of U and V are determined by protocol or configured by network devices.

[0027] In some implementations, the monitoring timing in the third time slot includes either the first monitoring timing in the third time slot or the second monitoring timing in the third time slot.

[0028] In some implementations, the monitoring timing in the fourth time slot includes either the first monitoring timing in the fourth time slot or the second monitoring timing in the fourth time slot.

[0029] In some implementations, the monitoring timing in the third time slot is used as the detection timing for the initial transmission of the first channel, and the monitoring timing in the fourth time slot is used as the detection timing for the repeated transmission of the first channel. This includes: determining a monitoring timing in the third time slot as the detection timing for the initial transmission of the first channel, and determining a monitoring timing in the fourth time slot as the detection timing for the repeated transmission of the first channel, according to the protocol agreement or network device configuration.

[0030] In some implementations, the following is also included before sending the SSB:

[0031] Receive first information from the terminal device, the first information being used to instruct the terminal device to support repeated transmission of the first channel, or for the terminal device to request repeated transmission of the first channel.

[0032] In some implementations, the following is also included before sending the SSB:

[0033] Send the first configuration information, which indicates that the first channel should be transmitted repeatedly.

[0034] In some implementations, the first channel includes:

[0035] The target physical downlink control channel (PDCCH) is used to schedule the physical downlink shared channel (PDSCH) that carries system information block SIB1.

[0036] A third aspect of this application provides a method for counting blind detection counts, applied to a terminal device. The method includes: receiving a candidate first channel in a first time unit and / or a second time unit, wherein the first time unit is the time unit for the initial transmission of the candidate first channel and the second time unit is the time unit for repeated transmission of the candidate first channel; and counting the candidate first channel received in the first time unit and / or the second time unit into the blind detection count.

[0037] The number of blind detections serves as the basis for conducting blind detections within the capabilities of the terminal device. That is, if the number of blind detections exceeds the terminal's capabilities, a priority is used to determine whether to perform blind detection on the candidate first channel. If the number of blind detections does not exceed the terminal's capabilities, blind detection is performed on the candidate first channel that is included in the number of blind detections. Therefore, the statistical method for the number of blind detections is beneficial for adjusting the terminal device's detection method for the candidate first channel, taking into account both the terminal device's capabilities and ensuring sufficient detection of the candidate first channel.

[0038] In some implementations, the second time unit includes the time unit of the last repeated transmission candidate first channel.

[0039] In some implementations, there are multiple second time units.

[0040] A fourth aspect of this application provides a communication apparatus including a module for performing the methods provided in the first, second, and third aspects of this application.

[0041] The fifth aspect of this application provides an electronic device, which includes: one or more processors, a memory, and a touch screen; the memory is used to store program code; the processor is used to run the program code, causing the electronic device to implement the methods provided in the first, second, and third aspects of this application.

[0042] A sixth aspect of this application provides a computer-readable storage medium having instructions stored thereon that, when executed on an electronic device, cause the electronic device to perform the methods provided in the first, second, and third aspects of this application.

[0043] The seventh aspect of this application provides a computer program product having stored thereon that, when executed on an electronic device, causes the electronic device to implement the methods provided in the first, second, and third aspects of this application.

[0044] An eighth aspect of this application provides a chip system comprising: at least one processor and an interface, the interface being configured to receive code instructions and transmit them to the at least one processor; the at least one processor executing the code instructions to implement the methods provided in the first, second, and third aspects of this application.

[0051] The terms "first," "second," and "third," etc., used in this application specification, claims, and drawings are used to distinguish different objects, not to limit a specific order.

[0052] In the embodiments of this application, the words "in some implementations" or "for example" are used to indicate examples, illustrations or descriptions, and should not be construed as being more preferred or more advantageous than other embodiments or designs.

[0055] Terminal devices can take various forms, such as mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, vehicle-mounted terminal devices, wireless terminal devices in self-driving technology, wireless terminal devices in remote medical care, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, wearable terminal devices, and so on.

Terminal devices can also be fixed terminal devices or mobile terminal devices.

[0056] Access network equipment can be terrestrial base stations or non-terrestrial network (NTN) equipment. NTN equipment can also be called base stations and / or satellite access nodes (SAN).

[0057] A base station is any device located on the network side with wireless transceiver capabilities, including but not limited to: evolved Node Bs (NodeBs, eNBs, or e-NodeBs) in LTE, base stations (gNodeBs or gNBs) or transmission receiving points / transmission reception points (TRPs) in new radio (NR), base stations evolved later in 3GPP, access nodes, wireless relay nodes, and wireless backhaul nodes in Wi-Fi systems.

A base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. Base stations can communicate with terminal devices, or they can communicate with terminal devices through relay stations.

[0058] To address the problem of poor communication link quality hindering normal communication, the communication method provided in the embodiments of this application enhances the transmission and reception performance of the channel. Specifically, the network device repeatedly transmits information for a specific channel, and correspondingly, the terminal device performs multiple checks on the information for that specific channel to increase the probability of correctly detecting the information, thereby improving the likelihood of normal communication.

[0059] This application provides a communication method that can be applied to a terminal device. Unless otherwise specified, the "terminal device" in this application can refer to the terminal device itself, a component within the terminal device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The method includes: acquiring a synchronization signal and a Physical Broadcast Channel Block (SSB), wherein the SSB includes a first SSB and / or a second SSB, the first SSB is associated with a first time slot, the second SSB is associated with a second time slot, and the first and second time slots contain monitoring opportunities for detecting the first channel; using the monitoring opportunity in a third time slot as the detection opportunity for the initial transmission of the first channel, and using the monitoring opportunity in a fourth time slot as the detection opportunity for the repeated transmission of the first channel, wherein the third time slot is determined based on the first time slot, and the fourth time slot is determined based on the second or third time slot.

[0060] Accordingly, the embodiments of this application provide a communication method that can be applied to network devices. Unless otherwise specified, the "network device" in the embodiments of this application can refer to the network device itself, or a component in the network device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device. The method includes: sending a synchronization signal and a Physical Broadcast Channel Block (SSB), wherein the SSB includes a first SSB and / or a second SSB, the first SSB is associated with a first time slot, the second SSB is associated with a second time slot, and the first and second time slots contain monitoring opportunities for detecting the first channel; using the monitoring opportunity in a third time slot as the opportunity for the initial transmission of the first channel, and using the monitoring opportunity in a fourth time slot as the opportunity for repeated transmission of the first channel, wherein the third time slot is determined based on the first time slot, and the fourth time slot is determined based on the second or third time slot.

[0061] It is evident that both terminal devices and network devices can determine the timing of initial and repeated transmissions of the first channel based on the time slot associated with the SSB. Repeated transmissions can increase the likelihood that the first channel will be correctly detected by the terminal device, thereby facilitating normal communication and improving communication reliability.

[0062] The communication method provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings. In the following embodiments, taking the target physical downlink control channel PDCCH as an example, the target PDCCH is the PDCCH used to schedule the physical downlink shared channel (PDSCH) carrying the System Information Block (SIB) 1.

[0063] In the following embodiments, numbers such as S11 and S12 do not represent the execution order.

[0064] Figure 1 This is a flowchart illustrating a communication method provided in an embodiment of this application. Figure 1 Includes:

[0065] S11. The terminal device sends the first information, and the corresponding network device receives the first information.

[0066] For example, the first information is used to instruct the terminal device to support repeated transmission of the first channel, or to request repeated transmission of the first channel by the terminal device. Repeated transmission refers to two or more transmissions within a specific time period, such as a specific time period of 20 milliseconds.

[0067] In some implementations, the terminal device has retransmission detection capability, and the first information is used to instruct the terminal device to support repeated transmission of the first channel. In other implementations, if the terminal device detects that the network quality does not meet the requirements, it sends the first information requesting repeated transmission of the first channel.

[0068] Understandably, whether the terminal device indicates support for repeated transmission of the first channel or requests repeated transmission of the first channel, the network device decides whether to repeat the first channel.

[0069] If the network device decides not to retransmit the first channel, subsequent transmissions will proceed according to the existing protocol. In the embodiments of this application, it is assumed that the network device decides to retransmit the first channel.

[0070] Understandably, S11 can be an optional step and may not be executed.

[0071] S12. The network device sends a synchronization signal and a physical broadcast channel block (SSB), and the terminal device receives the SSB accordingly.

[0072] The SSB includes the primary synchronization signal (PSS), the secondary synchronization signal (SSS), and the physical broadcast channel PBCH.

[0073] The PBCH message contains the master information block (MIB) and the PBCH payload.

[0074] In some cases, SSB is also called synchronization signal (SS) / PBCH, therefore, SS / PBCH and SSB are understood as equivalent.

[0075] Beamforming technology associates each SSB with a specific beam direction to achieve wide-area coverage and precise beam management. The SSB index is mapped to beam information (such as ID); that is, the SSB is mapped to the physical beam direction via the index. In this embodiment, the SSBs sent by the network device have different indices.

[0076] S13. The terminal device selects at least two SSBs with better quality from the received SSBs.

[0077] In some implementations, the SSB with better quality is selected based on the relationship between the measurement parameters carrying SSB information and their corresponding thresholds. Examples of measurement parameters include, but are not limited to, at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), and Signal-to-Interference plus Noise Ratio (SINR). The thresholds corresponding to each measurement parameter can be agreed upon through a protocol, configured by the network device, or determined by the terminal device itself.

[0078] In the embodiments of this application, two SSBs with better quality are selected as an example.

[0079] For ease of description, the two SSBs with better quality are referred to as the first SSB and the second SSB, respectively. The first SSB can also be called SSB(i) and the second SSB can also be called SSB(j), where i and j are SSB indices, and i and j are both 0 or positive integers.

[0080] S14. The network device determines the timing of the initial transmission of the first channel and the timing of the repeated transmission of the first channel based on the MO associated with the first SSB and / or the MO associated with the second SSB.

[0081] The SSB is associated with the Monitoring Occasion (MO) of the first channel. In this embodiment, the first channel is the PDCCH used to schedule the PDSCH of SIB1. This PDCCH is a PDCCH in the common search space of type 0 (referred to as Type-0CSS). The SSB's association with the MO of the first channel can be understood as follows: the MIB in the SSB indicates the information used to configure Type-0CSS, and the MO of the first channel is determined based on the information associated with the SSB.

[0082] Specifically, the time slot containing MO is based on the index i of O, M, and SSB, the subcarrier spacing μ, and the number of time slots within a system frame. As shown in equation (1):

[0083] When the following equation (2) is satisfied, time slot n0 is located in a system frame with an even frame number; otherwise, time slot n0 is located in a system frame with an odd frame number.

[0084]

[0085] O is the offset of the SSB start symbol within the time slot (also known as the start offset), in milliseconds (ms). Its values ​​in Frequency Range 1 (FR1) include {0, 2, 5, 7}, and its values ​​in FR2 include {0, 2.5, 5, 7.5}.

[0086] M represents the time slot overlap of MOs associated with adjacent SSB indices of Type-0 CSS PDCCH. The values ​​include {1 / 2, 1, 2}. 1 / 2 means that an MO associated with an SSB index occupies 1 / 2 time slots and adjacent MOs associated with SSB indices completely overlap. 1 means that an MO associated with an SSB index occupies one time slot and one MO among adjacent MOs associated with SSB indices overlaps. 2 means that an MO associated with an SSB index occupies two consecutive time slots and adjacent MOs associated with SSB indices do not overlap at all.

[0087] For example, assuming O is 0, the time slot where the MO associated with an SSB index is located is: in, It also indicates the number of time slots between MOs.

[0088] It is understandable that, based on equation (3), the time slot where the MO associated with SSB(i) is located and the time slot where the MO associated with SSB(j) is located can be obtained. The time slot where the MO associated with SSB(i) is located is called the first time slot n0(i), and the time slot where the MO associated with SSB(j) is located is called the second time slot n0(j).

[0089] It is understood that the time slot m or m-time slot mentioned in this application refers to the time slot with time slot index m, where m is 0 or a positive integer.

[0090] In this embodiment, the network device determines the timing of the initial transmission of the first channel (i.e., the monitoring timing in the third time slot) and the timing of the repeated transmission of the first channel (i.e., the monitoring timing in the fourth time slot) based on any one of the following methods 1-6:

[0091] Method 1: The third time slot is the first time slot, that is, the third time slot is the time slot with time slot index n0(i); the fourth time slot is the Vth time slot after the third time slot, that is, the time slot index of the fourth time slot = the time slot index of the third time slot + V, where V is an integer greater than or equal to 1.

[0092] The third time slot is n0(i), which is beneficial for compatibility with existing protocols. The fourth time slot is the Vth time slot after the third time slot, which is beneficial for more flexible selection of the fourth time slot.

[0093] When V takes the value 1, the fourth time slot is the next time slot after the third time slot. The next time slot after the third time slot refers to a time slot that is consecutive to the third time slot after the third time slot, that is, the fourth time slot is n0(i)+1.

[0094] Each time slot contains at least one MO (Measuring Optical Module). The MO for initial transmission of the first channel can be selected from the MOs in the third time slot, and the MO for repeated transmission of the first channel can be selected from the MOs in the fourth time slot. That is, according to the protocol or network device configuration, one monitoring opportunity in each of the third and fourth time slots is determined as the detection opportunity for the first channel. The monitoring opportunity in the third time slot is used for initial transmission of the first channel, and the monitoring opportunity in the fourth time slot is used for repeated transmission of the first channel.

[0095] For example, when M is 1 / 2, both the third and fourth time slots contain two MOs. In this case, the first or second MO in the third time slot can be selected as the MO for initial transmission of the first channel, and the first or second MO in the fourth time slot can be selected as the MO for repeated transmission of the first channel.

[0096] In this embodiment, taking V as an example and considering the time slot where MO is located and the selection method of MO, the location of MO used to transmit the first channel includes any one of the following options or any combination of the following options:

[0097] Option 1: The first MO in slot n0(i) and the first MO in slot n0(i)+1.

[0098] Option 2: M is 1 / 2, the first MO in slot n0(i) and the second MO in slot n0(i)+1.

[0099] Option 3: M is 1 / 2, the second MO in slot n0(i) and the first MO in slot n0(i)+1.

[0100] Option 4: M is 1 / 2, the second MO in slot n0(i) and the second MO in slot n0(i)+1.

[0101] In the above options, the MO in the previous time slot is used for the initial transmission of the first channel, and the MO in the subsequent time slot is used for repeated transmission of the first channel. It is understood that this embodiment uses one MO for repeated transmission of the first channel as an example, but this is not a limitation. Multiple MOs can be selected for repeated transmission of the first channel, thereby achieving multiple repeated transmissions of the first channel and further improving communication reliability. The selection method for each MO used for repeated transmission of the first channel will not be elaborated here.

[0102] In summary, Table 1 shows examples of the locations of the third and fourth time slots and MO when index i and M take different values:

[0103] Table 1

[0104]

[0105] In Table 1, when i = 0 and M = 1 / 2, based on equation (1), the third time slot n0(i) is time slot 0, that is, the number of the third time slot is 0. Correspondingly, the fourth time slot is time slot 1, that is, the number of the fourth time slot is 1. Since the number of time slots between MO is M = 1 / 2, Table 1 takes MO in time slot 0 as an example. Alternatively, MO can also be in time slot 1. The cases of other values ​​of M and i in Table 1 are similar and will not be repeated here.

[0106] Method 2: The third time slot is the next time slot after the first time slot, that is, the third time slot is the time slot with time slot index n0(i)+1, and the fourth time slot is the Vth time slot after the third time slot. That is, the time slot index of the fourth time slot = the time slot index of the third time slot + V, where V is an integer greater than or equal to 1. The fact that the fourth time slot is the Vth time slot after the third time slot allows for more flexible selection of the fourth time slot.

[0107] Taking V as a value of 1 as an example, the fourth time slot is n0(i)+2. In this example, some options in method 2 include any one of the following options or any combination of the following options:

[0108] Option 1: The first MO in slot n0(i)+1 and the first MO in slot n0(i)+2.

[0109] Option 2: M is 1 / 2, the first MO in slot n0(i+1) and the second MO in slot n0(i+2).

[0110] Option 3: M is 1 / 2, the second MO in slot n0(i+1) and the first MO in slot n0(i+2).

[0111] Option 4: M is 1 / 2, the second MO in slot n0(i+1) and the second MO in slot n0(i+2).

[0112] Method 3: The third time slot is the first time slot, that is, the third time slot is the time slot with time slot index n0(i), and the fourth time slot is the second time slot, that is, the fourth time slot is the time slot with time slot index n0(j). It can be understood that n0(i) and n0(j) may be continuous or discontinuous.

[0113] Similar to methods 1 and 2, a time slot contains at least one MO. A MO can be selected from the MOs in the third time slot as the timing for the initial transmission of the first channel, and a MO can be selected from the MOs in the fourth time slot as the timing for the repeated transmission of the first channel.

[0114] Method 3 includes any one of the following options or any combination of the following options:

[0115] Option 1: The first MO in slot n0(i) and the first MO in slot n0(j).

[0116] Option 2: M is 1 / 2, the first MO in slot n0(i) and the second MO in slot n0(j).

[0117] Option 3: M is 1 / 2, the second MO in slot n0(i) and the first MO in slot n0(j).

[0118] Option 4: M is 1 / 2, the second MO in slot n0(i) and the second MO in slot n0(j).

[0119] Method 4: The third time slot is the first time slot, that is, the third time slot is the time slot with time slot index n0(i), and the fourth time slot is the U-th time slot after the second time slot, that is, the time slot index of the fourth time slot = the time slot index of the second time slot + U, where U is an integer greater than or equal to 1.

[0120] Taking U as 1 as an example, the fourth time slot is the next time slot after the second time slot, that is, the fourth time slot is n0(j)+1. The next time slot after the second time slot refers to a time slot that is after the second time slot and is continuous with the second time slot.

[0121] In this example, method 4 includes any one of the following options or any combination of the following options:

[0122] Option 1: The first MO in slot n0(i) and the first MO in slot n0(j)+1.

[0123] Option 2: M is 1 / 2, the first MO in slot n0(i) and the second MO in slot n0(j)+1.

[0124] Option 3: M is 1 / 2, the second MO in slot n0(i) and the first MO in slot n0(j)+1.

[0125] Option 4: M is 1 / 2, the second MO in slot n0(i) and the second MO in slot n0(j)+1.

[0126] Method 5: The third time slot is the next time slot after the first time slot, that is, the third time slot is the n0(i)+1 time slot, and the fourth time slot is the second time slot, that is, the fourth time slot is the time slot with time slot index n0(j).

[0127] Option 5 includes any one of the following options or any combination of the following options:

[0128] Option 1: The first MO in slot n0(i)+1 and the first MO in slot n0(j).

[0129] Option 2: M is 1 / 2, the first MO in slot n0(i)+1 and the second MO in slot n0(j).

[0130] Option 3: M is 1 / 2, the second MO in slot n0(i)+1 and the first MO in slot n0(j).

[0131] Option 4: M is 1 / 2, the second MO in slot n0(i)+1 and the second MO in slot n0(j).

[0132] Method 6: The third time slot is the next time slot after the first time slot, that is, the third time slot is the time slot with time slot index n0(i)+1, and the fourth time slot is the U-th time slot after the second time slot, that is, the time slot index of the fourth time slot = the time slot index of the second time slot + U, where U is an integer greater than or equal to 1.

[0133] Taking U as an example, the fourth time slot is the next time slot after the second time slot, that is, the fourth time slot is the n0(j)+1 time slot.

[0134] In this example, method 6 includes the following optional methods:

[0135] Option 1: The first MO in slot n0(i)+1 and the first MO in slot n0(j)+1.

[0136] Option 2: M is 1 / 2, the first MO in slot n0(i)+1 and the second MO in slot n0(j)+1.

[0137] Option 3: M is 1 / 2, the second MO in slot n0(i)+1 and the first MO in slot n0(j)+1.

[0138] Option 4: M is 1 / 2, the second MO in slot n0(i)+1 and the second MO in slot n0(j)+1.

[0139] The values ​​of V and U mentioned above can be determined based on protocols (such as 3GPP TS 38.213) or configured by network devices.

[0140] It is understood that network devices use any one of the above methods 1 to 6 based on configuration information (such as the protocol corresponding to the embodiments of this application).

[0141] The combinations of the third and fourth time slots in methods 1-6 above are merely examples. These examples are covered by the following selection rules for the third and fourth time slots: the third time slot is the first time slot, or the third time slot is the next time slot after the first time slot. In some implementations, the fourth time slot is the second time slot, or the fourth time slot is the U-th time slot after the second time slot, where U is an integer greater than or equal to 1. In other implementations, the fourth time slot is the V-th time slot after the third time slot, where V is an integer greater than or equal to 1.

[0142] The third time slot is the first time slot or the next time slot after the first time slot, which is compatible with the existing protocol's method of determining time slots based on SSB. The fourth time slot is determined based on U or V, providing greater flexibility. For example, if the third and fourth time slots are determined only based on the first SSB, as in method 1 above, the second SSB may not need to be transmitted.

[0143] S15. The terminal device determines the detection timing for the initial transmission of the first channel and the detection timing for the repeated transmission of the first channel based on the MO associated with the first SSB and / or the MO associated with the second SSB.

[0144] The terminal device determines the detection timing for the initial transmission of the first channel and the detection timing for the repeated transmission of the first channel based on any one of the methods 1-6 above, which will not be elaborated here. It is understood that the network device and the terminal device must use the same method.

[0145] The terminal device uses any one of the above methods 1 to 6 based on configuration information (such as the protocol corresponding to the embodiments of this application) or indication information or configuration information from the network device.

[0146] The execution order of S15 and S14 is not a limitation.

[0147] The communication method provided in this embodiment involves the network device determining the timing for the initial transmission and at least one repeated transmission of information to the target channel. Correspondingly, the terminal device determines the timing for detecting information to multiple target channels, laying the foundation for repeated transmission of information, increasing the likelihood of the terminal device successfully detecting information, and helping to ensure normal communication.

[0148] It is understandable that after determining the timing for transmitting the first channel, the network device may transmit the first channel at that timing, or it may not transmit the first information, or it may transmit the first channel at the initial timing for transmitting the first channel without repeating the transmission of the first channel. After determining the timing for detecting the first channel, the terminal device may detect the first channel at that timing, or it may not detect the first channel, or it may detect the first channel only once, such as detecting the first channel at the initial timing for transmitting the first channel, or detecting the first channel at the timing for repeating the transmission of the first channel, etc. Examples will be given in the following embodiments.

[0149] Figure 2 This embodiment provides another communication method, the main difference from the above embodiments being the addition of exemplary steps for transmitting and detecting the first channel. Figure 2 Includes:

[0150] S21. The network device sends the first configuration information.

[0151] For example, the first configuration information indicates that the first channel should be transmitted repeatedly. Accordingly, the terminal device receives the first configuration information.

[0152] Understandably, S21 can be an optional step.

[0153] S22. Network devices broadcast SSB. Correspondingly, terminal devices receive the SSB.

[0154] S23. The terminal equipment acquires the first SSB and / or the second SSB that meet the quality requirements.

[0155] For example, a first SSB is associated with a first time slot, and a second SSB is associated with a second time slot. Both the first and second time slots contain an MO for detecting the first channel.

[0156] S24. The network device uses the monitoring time in the third time slot as the time for the initial transmission of the first channel, and uses the monitoring time in the fourth time slot as the time for the repeated transmission of the first channel.

[0157] S25. The terminal device uses the monitoring opportunity in the third time slot as the detection opportunity for the initial transmission of the first channel, and uses the monitoring opportunity in the fourth time slot as the detection opportunity for the repeated transmission of the first channel.

[0158] In this embodiment, S24 and S24 can be implemented in any of the methods 1-5 of the above embodiments.

[0159] S26. The network device transmits the first channel at the initial transmission time of the first channel.

[0160] S27. The network device retransmits the first channel when it is being retransmitted on the first channel.

[0161] S28. Number of blind inspections of terminal equipment.

[0162] To improve battery life and other objectives, the number of blind checks performed by a terminal device within a time slot cannot exceed its blind check capability. For example, if the number of blind checks performed by the terminal device within a time slot is N, then N must be equal to or less than the blind check capability M. If N is greater than M, then some objects that need to be blind checked must be discarded; discarding means not performing blind checks.

[0163] The PDCCH is the object that needs to be blindly detected. In this embodiment, since the target PDCCH is repeatedly transmitted, it is necessary to consider the statistical method of the number of blind detections in order to both improve the probability of correctly detecting the target PDCCH and be compatible with the current blind detection method.

[0164] A PDCCH received by a terminal device but not yet detected can be called a PDCCH candidate.

[0165] In this embodiment, where the first channel is the target PDCCH, the example of the target candidate first channel is the target PDCCH candidate. It is understood that the PDCCH candidate includes the target PDCCH candidate and other PDCCH candidates, and the target PDCCH candidate includes the target PDCCH candidate for the initial transmission and the target PDCCH candidate for retransmission.

[0166] The terminal device counts the number of blind checks for the target PDCCH candidate in any of the following ways:

[0167] Method 1: The candidate first channel (taking the target PDCCH candidate as an example) in the third and fourth time slots is included in the blind detection count N. That is, the target PDCCH transmitted for the first time and the target PDCCH transmitted at least once are included in the blind detection count N. For example, after the target PDCCH is received in the third time slot, the blind detection count N is increased by 1, and after the target PDCCH is received in the fourth time slot, the blind detection count N is increased by 1.

[0168] The target PDCCH is included in the number of blind detections N, which means that the target PDCCH may be detected multiple times, thus increasing the probability of correctly detecting the target PDCCH.

[0169] Method 2: The candidate first channel in the third time slot is counted in the blind detection count N, while the candidate first channel in the fourth time slot is not counted in the blind detection count N. For example, after receiving the target PDCCH in the third time slot, the blind detection count is N plus 1. After receiving the target PDCCH in the fourth time slot, the blind detection count N remains unchanged, that is, the repeatedly transmitted target PDCCH is not counted in the blind detection count.

[0170] Method 3: The candidate first channel in the third time slot is not counted in the blind detection count N, while the candidate first channel in the fourth time slot is counted in the blind detection count. For example, after receiving the target PDCCH in the third time slot, the blind detection count remains unchanged, that is, the initially transmitted target PDCCH is not counted in the blind detection count. After receiving the target PDCCH in the fourth time slot, the blind detection count N is incremented by 1. In other words, this method counts the repeatedly transmitted target PDCCH in the blind detection count N.

[0171] In some implementations, the target PDCCH is transmitted repeatedly. In this case, if the repeatedly transmitted target PDCCH needs to be counted in the blind detection count, then in order not to occupy too many blind detection counts, the target PDCCH transmitted once is counted in the blind detection count. For example, the target PDCCH transmitted last time is counted in the blind detection count.

[0172] Including the target PDCCH from the initial transmission or retransmission in the blind detection count helps save resources.

[0173] S29. When the number of blind detections exceeds the detection capability of the terminal device, the terminal device determines whether to detect the candidate first channel based on the priority of the candidate first channel.

[0174] In some implementations, if the target PDCCH candidate has a higher priority than other PDCCH candidates, the other PDCCH candidates are discarded first, and the target PDCCH candidate is blindly detected with a capability no greater than the detection limit. In other implementations, if the target PDCCH candidate has a lower priority than other PDCCH candidates, the target PDCCH candidate is discarded first.

[0175] The priority of the first candidate channel is pre-agreed upon by the protocol or configured by the network device.

[0176] It is understandable that, when the number of blind checks does not exceed the detection capability of the terminal device, all received PDCCH candidates will be checked.

[0177] The method provided in this embodiment allows the terminal device to adjust the number of blind detections of the first channel by statistically analyzing the number of blind detections, thus ensuring normal communication while also taking into account the terminal's capabilities.

[0178] Figure 2 Taking one time slot as an example, this paper explains the statistics of blind detection times and the blind detection method. Alternatively, a time unit can also be S consecutive time slots or Q consecutive OFDM symbols, where S and Q are both integers greater than or equal to 1.

[0179] The above method for counting the number of blind inspections can be extended to other objects that require blind inspection, and is not limited to PDCCH.

[0180] Due to limitations in terminal device capabilities and power consumption considerations, the number of objects, such as PDCCH candidates, that a terminal device can detect within a single time unit (e.g., slot, span) is limited. When the number of objects configured to be detected within a single time unit exceeds the terminal device's detection capacity limit, the terminal device will perform detection according to a predetermined priority, excluding lower-priority objects.

[0181] The number of blind checks is a count of the objects to be checked. Taking PDCCH candidates as an example, the number of blind checks determines whether blind checks are performed on high-priority PDCCH candidates based on priority, or on all PDCCH candidates. Therefore, how to count the number of blind checks to clarify the blind check method of the terminal device is a problem that needs to be solved.

[0182] Embodiments of this application also provide a method for counting the number of blind inspections, including:

[0183] 1. The network device sends the first candidate channel.

[0184] 2. The terminal device receives the candidate first channel in the first time unit and / or the second time unit.

[0185] A time unit can be either a series of S time slots or a series of Q OFDM symbols, where S and Q are both integers greater than or equal to 1.

[0186] In conjunction with the above embodiments, an example of a candidate first channel is a PDCCH candidate.

[0187] For example, the first time unit is the time unit for the initial transmission of the candidate first channel, and the second unit is the time unit for the repeated transmission of the candidate first channel.

[0188] 3. The terminal device counts the candidate first channel received in the first time unit and / or the second time unit into the blind detection count.

[0189] In this embodiment, taking the first time unit as the third time slot and the second time unit as the fourth time slot as an example, and the candidate first channel as the PDCCH candidate as an example, the method of counting the number of blind detections for the candidate first channel received in the first time unit and the second time unit can be referred to the method 1-method 3 described in S28, which will not be repeated here.

[0190] In some implementations, the second time unit includes the time unit of the last repeated transmission candidate first channel.

[0191] In some implementations, there are multiple second time units.

[0192] Understandably, by counting the number of blind detections and combining it with priority configuration, the detection method of the terminal device for the candidate first channel can be adjusted. This can take into account both the capabilities of the terminal device and the full detection of the candidate first channel. For example, if it is necessary to fully detect the candidate first channel, the candidate first channel received in most time units can be excluded from the blind detection count. If it is necessary to save the power consumption of the terminal device, the candidate first channel received in most time units can be included in the blind detection count.
