Description

[0001] This application claims priority to a Chinese patent application filed with the Intellectual Property Office of the People's Republic of China on June 17, 2021, with application number 202110670128.9 and invention name "A Method for Sending a Control Message", all contents of which are incorporated by reference in this application. Technical Field

[0002] The embodiments of the present application relate to the field of communication technology, and in particular, to an information transmission method and a communication device. Background Art

[0003] In the unlicensed frequency band, in order to avoid transmission interference between devices, the device can use the listen-before-talk (LBT) mechanism to determine whether it can occupy the channel before accessing the channel. For example, the device can first determine whether there are other devices on the channel. If no other device is using the channel, it can occupy the channel and use the channel for control information or data transmission; if other devices are occupying the channel, the device needs to wait for the data transmission of other devices to end before occupying the channel. This process causes a large delay, which affects the transmission performance.

[0004] In wireless communication systems such as new radio (NR) systems, downlink control information (DCI) is generally used to schedule the data reception and transmission of terminal devices. For unlicensed millimeter wave bands, in order to reduce the control information transmission delay caused by LBT, access network equipment usually configures multiple search spaces (SS) for the terminal device to transmit the same DCI, and the terminal device can blindly detect DCI on the multiple SSs.

[0005] The access network equipment performs LBT in the beam directions corresponding to multiple SSs sequentially or simultaneously. When it is determined that the channel in one of the beam directions is available, the SS corresponding to the beam is used to send DCI, and the same DCI is not sent additionally on other SSs; while the terminal will always perform blind detection on multiple SSs. Such a design will lead to unnecessary blind detection energy consumption. Summary of the invention

[0006] The embodiments of the present application provide an information transmission method and a communication device, which can reduce the energy consumption overhead of blind detection.

[0007] In a first aspect, an embodiment of the present application provides an information transmission method, the method comprising:

[0008] Acquire first configuration information, where the first configuration information is used to configure a plurality of listening positions and receiving spatial domain filtering parameter indication information associated with each of the plurality of listening positions, the plurality of listening positions being used for detecting control information; and at least two of the plurality of listening positions being associated with different receiving spatial domain filtering parameter indication information;

[0009] Control information is detected through a first listening position, and it is determined whether to detect the control information through a second listening position based on the detection result; wherein the multiple listening positions include the first listening position, and the second listening position is any one of the multiple listening positions except the first listening position.

[0010] In the above design, multiple listening positions are configured to correspond to at least two receiving beam directions, and a decision is made based on the detection result of the control information at one listening position whether to detect at other listening positions. This can reduce the energy consumption overhead of blindly detecting the control information in at least two receiving beam directions.

[0011] In a possible design, the start time of the second listening position is not earlier than that of the first listening position. With such a design, it is possible to decide as early as possible whether to detect at other listening positions.

[0012] In one possible design, if control information is detected through the first listening position, the control information is not detected through the second listening position; alternatively, if control information is not detected through the first listening position, the control information is detected through the second listening position.

[0013] In one possible design, the detecting control information through the first listening position includes: detecting first indication information in the control information through the first listening position, the first indication information being used to indicate whether to detect the control information through the second listening position or not. Based on this, if the first indication information in the control information is detected through the first listening position, it is determined whether to detect the control information through the second listening position based on the first indication information; or, if the first indication information in the control information is not detected through the first listening position, the control information is detected through the second listening position.

Such a design can implement control information at one listening position to indicate that detection should not be performed at other listening positions, thereby reducing unnecessary blind detection energy consumption.

[0020] In one possible design, the method further includes: sending control information through a first listening position, the control information including first indication information, the first indication information being used to indicate whether to detect the control information through a second listening position or not; wherein the multiple listening positions include the first listening position, and the second listening position is any one of the multiple listening positions except the first listening position. Such a design can implement the first indication information in the control information at one listening position to indicate whether to detect at other listening positions, thereby reducing unnecessary blind detection energy consumption overhead.

[0026] In the above design, multiple listening positions are configured to correspond to the same receiving beam direction, and a decision is made whether to detect at other listening positions based on the detection result of the first information at the first listening position, which can reduce unnecessary blind detection energy consumption overhead in the same receiving beam direction.

[0027] In one possible design, if the first information is detected through the first listening position, the control information is detected through the second listening position; or, if the first information is not detected through the first listening position, the control information is not detected through the second listening position.

[0028] In a possible design, the first listening position is a pre-determined listening position among the multiple listening positions. For example, the first listening position is a position that is earlier in time among the multiple listening positions. With such a design, it is possible to decide as early as possible whether to detect at other listening positions.

[0119] Below, some of the terms provided in the embodiments of the present application are explained to facilitate understanding by those skilled in the art:

[0120] (1) Control-resource set (CORESET) and search space (SS)

[0121] The search space SS may also be a search space set (SSS). The access network device may configure a CORESET and a search space (hereinafter referred to as SS) for the terminal device to transmit some relevant information, such as downlink control information (DCI). Exemplarily, in the NR system, the downlink control information (DCI) between the access network device and the terminal device is carried on the physical downlink control channel (PDCCH). The SS is associated with the CORESET to determine the time-frequency position for blind detection of the PDCCH. It can be understood that blind detection may be referred to as monitoring, detection, etc., and blind detection of PDCCH may be understood as blind detection of DCI, monitoring of DCI, detection of DCI, etc. That is, the terminal device may determine some candidate periodic time-frequency resource positions according to the CORESET and SS configured by the access network device, and blindly detect the PDCCH at these positions, so as to determine whether the access network device sends DCI and where to send DCI, whether to schedule data transmission of the UE, and report channel state information.

[0122] The configuration information of CORESET includes the frequency domain position, number of symbols, resource mapping mode and transmission configuration indicator (TCI) of CORESET. The configuration information of SS includes the type of SS (such as cell-level SS, user (UE)-level SS), the period of SS (in time slots) and the time offset in the period, the starting monitoring symbol position in the monitoring time slot (or detection time slot), the number of candidate physical downlinks under one or more aggregation levels, the supported DCI format and other information.

[0123] For example, Figure 2The figure illustrates a configuration method of a control resource set and a search space. The access network device configures two CORESETs for the terminal device, including CORESET1 and CORESET2. CORESET1 occupies 2 symbols in the time domain and 12 physical resource blocks (PRBs) in the frequency domain, while CORESET2 occupies 1 symbol in the time domain and 24 PRBs in the frequency domain. At the same time, the access network device also configures three SSs for the terminal device, which are denoted as SS0, SS1, and SS2. SS0 and SS1 are associated with CORESET1; the period of SS0 is 1 slot, and the starting symbol is symbol 0 in the first slot in the period; the period of SS1 is 2 slots, and the starting symbol is symbol 3 in the first slot in the period. SS2 is associated with CORESET2, the period of SS2 is 2 slots, and the starting symbol is symbol 0 in the first slot in the period.

[0124] (2) Transmission configuration indicator (TCI)

[0125] Among them, the transmission configuration indication may also be referred to as the transmission configuration indication, referred to as TCI. TCI is used to indicate the quasi co-location (QCL) source reference signal (reference signal, RS). The source RS may have a QCL relationship with the demodulation reference signal (demodulation reference signal, DMRS) of the PDCCH on the CORESET, and the TCI indication may be used for PDCCH reception and channel estimation. Specifically, TCI may be included in the configuration information of the CORESET and configured to the terminal device.

[0126] In the NR system, QCL is defined as follows: if the channel characteristics represented by one antenna port on a symbol can be inferred from the channel represented by another antenna port on a symbol, then the two channels can be considered to be QCL. The QCL relationship can be configured by a high-level layer, such as by a high-level layer configuring the QCL relationship through a transmission configuration indication state (TCI state). A TCI state may include a downlink reference signal and the QCL type of the reference signal, or a TCI state may include indication information of a first downlink reference signal and the QCL type corresponding to the reference signal and a second downlink reference signal and the QCL type corresponding to the reference signal. The QCL type corresponding to the second downlink reference signal is type-D. When a CORESET is configured or a TCI is activated, the receiving device may perform channel estimation when performing PDCCH blind detection on the CORESET based on the channel characteristics of the source RS indicated by the TCI.

[0127] The QCL involved in the embodiment of the present application is type D (typeD) defined in NR: {Spatial Rx parameter}, and the typeD indicates that the receiving spatial domain filtering parameters used by the two antenna ports are the same. If the source RS indicated by the TCI is a type-DQCLed RS, the TCI can also be used to assist the device receiving the TCI in determining the receiving spatial domain filtering parameters used for blind detection of PDCCH on the CORESET; wherein, the receiving spatial domain filtering parameters can be understood as receiving beams. Specifically, the access network device configures the TCI to the terminal device, and the terminal device can determine the source RS indicated by the TCI. RS Since the terminal device can generally obtain the receiving beam for receiving the source RS in the previous beam training and beam measurement process, the access network device configures the CORESET associated with the TCI for the terminal device, which can be understood as the transmission beam (or, the transmission spatial domain filtering parameters) used by the access network device when sending TCI on the CORESET is the same as the transmission beam used by the source RS corresponding to the previous sending of the TCI, so the terminal device can determine the receiving beam used for blind detection of PDCCH on the CORESET.

[0128] (3) Unlicensed frequency bands

[0129] Taking the NR system as an example, the frequency bands used mainly include FR1 and FR2. The frequency range of FR1 is 450MHz-6GHz, also known as sub 6GHz; the frequency range of FR2 is 24.25GHz-52.6GHz. In addition, it can be expanded to higher frequency bands such as 52.6GHz to 71GHz. FR2 and even higher frequency bands can also be called millimeter waves (mmWave).

[0130] The millimeter wave band has the advantage of large bandwidth. On the one hand, it can support the transmission of large data rates and low latency, and can be applied to various business scenarios such as enhanced mobile broadband (eMBB), augmented / virtual reality (augmented / virtual reality), mobile data offloading, short-distance direct communication, wireless backhaul links, etc. On the other hand, the large bandwidth can achieve higher time resolution in positioning, thereby correspondingly improving positioning accuracy. However, compared with the sub-6GHz band, the channel attenuation of the millimeter wave band is very large. The device sending the signal needs to use beamforming or other technologies to use specific spatial filtering parameters so that the energy of the signal can be concentrated in a specific direction (hereinafter referred to as the beam direction). Correspondingly, the device receiving the signal also needs to select the corresponding receiving beam direction to improve the equivalent channel gain between the transceiver devices and ensure the coverage performance and transmission data rate of the millimeter wave communication. Therefore, the deployment on the millimeter wave requires the beam training between the access network device and the terminal device to be done in advance, and one or more suitable transceiver beam pairs between the access network device and the terminal device are determined. When the access network device and the terminal device need to communicate, they use signaling interaction or default rules to agree on which transmit and receive beam pair to use at a certain time-frequency resource location. Combined with the type-D in the QCL relationship type introduced above, the access network device can configure an additional QCL type-D source RS in the TCI of the CORESET. This configuration method can indicate the following information to the terminal device: If the access network device sends DCI (carried on PDCCH) on the CORESET, the access network device will use the same beam as the source RS. Based on the previous beam training results, the terminal device can know which receiving beam to use for blind detection of PDCCH on the CORESET.

[0131] Part of the frequency band from 52.6GHz to 71GHz may be unlicensed, or unlicensed millimeter wave. In the unlicensed millimeter wave band, the device needs to use a directional listen-before-talk (LBT) mechanism, that is, to determine whether there are other devices occupying the channel in a specific receiving beam direction, and then use the transmitting beam corresponding to the receiving beam direction to send control information or data when it is determined that no other device is using the channel. However, when other devices are occupying the channel, the device needs to wait for the data transmission of other devices to end.

[0132] (4) The term "plural" as used in the present disclosure refers to two or more than two. "And / or" describes the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. In addition, it should be understood that although the terms first, second, etc. may be used to describe each object in the present disclosure, these objects should not be limited to these terms. These terms are only used to distinguish each object from each other.

[0133] (5) The terms "including" and "having" and any variations thereof mentioned in the description of this disclosure are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any method or design described in this disclosure as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other methods or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.

[0134] In communication systems such as NR systems, downlink control information DCI is generally used to schedule data transmission of terminal devices and report channel status information. Since the base station first needs to perform beamforming in the analog domain, at a certain moment, the base station is likely to only be able to perform LBT in one beam direction. When LBT fails in this direction, the base station may lose the transmission opportunity. For unlicensed millimeter wave bands, the control information transmission delay caused by the LBT mechanism can be reduced by enhancing the control channel.

[0135] In a possible solution, the access network device can reduce the control information transmission delay and the overall transmission delay by increasing the transmission opportunities of the control information. Specifically, the solution includes the following steps S1 to S4.

[0136] S1, after the beam training process, the access network device and the terminal determine multiple beam pairs with better signal quality, and then the access network device configures multiple TCIs for the terminal device according to the results of the beam training. The type-DQCL source RS in the multiple TCIs can be associated with the above-mentioned beam pairs with better signal quality.

[0137] S2, the access network device sends configuration information of multiple CORESETs to the terminal device, each CORESET includes a TCI as described in step S1.

[0138] S3, the access network device sends the configuration information of multiple SSs to the terminal device, each SS corresponds to a CORESET in step S2; and each SS is different in time, that is, the access network device configures the terminal device to perform blind detection of PDCCH at different times and in different beam directions.

[0139] S4, the access network equipment performs LBT in multiple beam directions sequentially or simultaneously. When it is determined that a channel in one of the beam directions is available, DCI (carried on PDCCH) is sent in the SS corresponding to the beam, and the terminal equipment can also perform blind detection on the PDCCH accordingly.

[0140] like Figure 3 As shown in the figure, the access network device configures three CORESETs and three corresponding SSs for the terminal device, which are recorded as CORESET1 and SS0, CORESET2 and SS1, and CORESET3 and SS2. The terminal device can perform blind detection on CORESET1 and SS0, CORESET2 and SS1, and CORESET3 and SS2 respectively. Each CORESET corresponds to a beam direction (TCI indication). When the access network device has DCI to send to the terminal device, it first performs LBT in the beam direction corresponding to CORESET1, but finds that the channel is occupied by other devices, and then performs LBT on CORESET2. After confirming that the channel is idle, it sends DCI to the terminal device. The access network device no longer performs LBT in the beam direction corresponding to CORESET3, and no longer sends the DCI additionally on CORESET3. Based on this, the terminal device will not detect DCI on CORESET1 and SS0, CORESET3 and SS2, but can successfully detect DCI on CORESET2 and SS1. However, for the terminal device, regardless of whether the blind detection of DCI is successful, blind detection will be performed on CORESET1 and SS0, CORESET2 and SS1, and CORESET3 and SS2.

[0141] The design in the above scheme improves the probability of LBT success of access network equipment and reduces the delay of sending DCI by configuring CORESET with different beam directions, but it will increase the blind detection overhead of terminal equipment.

[0142] Based on this, the embodiments of the present application provide an information transmission method and a communication device, which can reduce the transmission delay of control information and reduce the blind detection overhead of the device side receiving the control information. The information transmission method provided by the embodiments of the present application can be applied to the aforementioned communication system, such as Figure 1The illustrated communication system, when applied to the communication system, the device sending the control information may be an access network device, and the device receiving the control information may be a terminal device. In an embodiment of the present application, multiple listening positions may be configured on the terminal device side, and the access network device may indicate the blind detection strategy of multiple listening positions to the terminal device, or multiple listening positions may be configured to transmit the same information in association, and the terminal device may determine the blind detection strategy of multiple listening positions by itself.

[0143] The following describes in detail the blind detection strategy for multiple monitoring positions in conjunction with specific embodiments.

[0144] Figure 4 An information transmission method is illustrated, which mainly includes the following process.

[0145] S401: A first device sends first configuration information to a second device.

[0146] The first configuration information is used to configure multiple monitoring positions, and the second device can determine multiple monitoring positions according to the first configuration information, and the multiple monitoring positions are used to detect control information. It can also be understood that the monitoring position can also be called a monitor occasion (MO) or other names, which is not limited in the embodiments of the present application.

[0147] Specifically, the first device may be an access network device, and the second device may be a terminal device. Exemplarily, the control information may be downlink control information DCI.

[0148] Specifically, the first configuration information may include indication information of multiple listening positions, directly indicating the time-frequency position corresponding to each listening position. Alternatively, the first configuration information includes second configuration information and third configuration information, the second configuration information is used to configure the frequency domain positions of the multiple listening positions, and the third configuration information is used to configure the time domain positions of the multiple listening positions; or, the configuration information of the listening position (such as identification, time-frequency position, etc.) can be pre-deployed on the second device side, and the first device includes identifications of multiple listening positions in the first configuration information, then the second device determines the multiple listening positions according to the identifications of the multiple listening positions included in the first configuration information.

[0149] Optionally, the multiple listening positions configured by the first configuration information are associated, for example, the multiple listening positions are configured for transmitting the same control information. The second device can determine multiple associated listening positions based on the first configuration information. Alternatively, it can be understood that the first configuration information can also be used to indicate the association between the aforementioned multiple listening positions. The manner in which the first configuration information indicates the association between the multiple listening positions will be specifically described in the subsequent content.

[0150] Furthermore, the first configuration information may also include receiving spatial domain filtering parameter indication information associated with each of the multiple listening positions. For example, the receiving spatial domain filtering indication information may specifically be a transmission configuration indication TCI. TCI can be used to determine the receiving spatial domain filtering parameters, or TCI can be used to indicate the receiving spatial domain filtering parameters. Specifically, for any one of the multiple listening positions, a TCI associated with a listening position can be used by the second device to determine the receiving spatial domain filtering parameters used for blind detection at the listening position, and the receiving spatial domain filtering parameters may be the same as the receiving spatial domain filtering parameters used by the type D QCLedRS associated with the TCI previously received, or may be adjusted according to the receiving spatial domain filtering parameters used by the type D QCLedRS associated with the TCI previously received. The receiving spatial domain filtering parameters may also be understood as receiving beams. Accordingly, the first device will use a certain sending spatial domain filtering parameter when sending control information at the listening position. The first device configures a TCI associated with the listening position. When the first device sends control information at the listening position, the sending spatial domain filtering parameters used may be the same as the sending spatial domain filtering parameters used to send the type D QCLed RS associated with the TCI. The sending spatial domain filtering parameters may also be understood as the sending beam.

[0151] Based on this, the second device can determine the receiving spatial domain filtering parameters used when detecting control information through a listening position based on the TCI associated with the listening position. Specifically, the second device can determine the type D QCLed RS associated with the TCI based on the TCI associated with the listening position, and determine that the sending spatial domain filtering parameters used by the first device when sending control information at the listening position are the same or close to the sending spatial domain filtering parameters used to send the type D QCLed RS associated with the TCI. Then the second device can determine the receiving spatial domain filtering parameters corresponding to the sending spatial domain filtering parameters based on the sending spatial domain filtering parameters corresponding to the type D QCLed RS associated with the TCI and the results of the previous beam training, and the second device can use the receiving spatial domain filtering parameters corresponding to the TCI when detecting control information through the listening position.

[0152] Optionally, at least two of the multiple listening positions are associated with different receiving spatial domain filtering parameter indication information, that is, when the first device sends control information at multiple listening positions, at least two of the listening positions use different sending spatial domain filtering parameters (or sending beams) to send control information. Exemplarily, the first device can perform LBT in multiple sending beam directions, and multiple listening positions correspond one-to-one to the multiple sending beam directions, and different listening positions are associated with different TCI information. In addition, the first device can also use corresponding sending spatial domain filtering parameters when sending control information at the listening position corresponding to the successful LBT based on the results of LBT in each sending beam direction. In this way, the success rate of LBT can be increased and the delay in sending control information can be reduced.

[0153] S402: The second device detects control information through the first listening position, and determines whether to detect the control information through the second listening position according to the detection result.

[0154] The plurality of monitoring positions include the first monitoring position, for example, the first monitoring position is any one of the plurality of monitoring positions. The second monitoring position is any one of the plurality of monitoring positions except the first monitoring position.

[0155] Exemplarily, the second device determines whether to detect the control information through the second listening position according to the detection result, which can be implemented in the following manner: if the second device detects the control information through the first listening position, then the control information is not detected through the second listening position; or, if the second device does not detect the control information through the first listening position, then the control information is detected through the second listening position. It can be understood that the control information can be used to indicate whether to detect the control information through the second listening position.

[0156] In an optional implementation, the control information may be a first DCI, and the first DCI is used to schedule data transmission of the second device, report channel state information, etc. If the second device detects the first DCI at the first listening position, the second device may determine that it is not necessary to detect the control information at other listening positions except the first listening position.

[0157] For example, Figure 5aThe following illustrates a control information detection process. The first device configures three listening positions for the second device, which are recorded as MO1, MO2 and MO3. Different listening positions are associated with different TCIs, that is, different listening positions are associated with different beam directions. When the first device has a first DCI to send to the second device, the first device first performs LBT in beam direction 1, and finds that the channel in this direction is occupied by other devices, resulting in LBT failure. Correspondingly, the second device does not detect the first DCI using its corresponding receiving beam on MO1. Then the first device performs LBT in beam direction 2, and finds that no other device occupies the channel in this direction, that is, LBT is successful. Then the first device can send the first DCI on MO2 using beam direction 2 associated with MO2, and correspondingly, the second device can detect the first DCI on MO2 using the corresponding receiving beam. The first device will no longer perform LBT in beam direction 3, that is, it will no longer send the first DCI on MO3, and the second device will no longer detect the first DCI on MO3.

[0158] In another optional implementation, the control information may also be a newly defined second DCI, such as the second DCI may be a lightweight DCI, and the second DCI may be used only to indicate that the first device has no other control information to send at multiple listening positions. If the second device detects the second DCI at the first listening position, the second device may determine that it is not necessary to detect the control information at other listening positions other than the first listening position. Of course, it is understandable that for the aforementioned another optional implementation, the second DCI may not be redefined, but other types of indication information may be used to indicate that the first device has no other control information to send at multiple listening positions, such as: media access control control element (MAC CE); or, the existing DCI may be improved (for example: adding 1 bit indication information) to indicate that the first device has no other control information to send at multiple listening positions. The specific implementation may be determined according to actual conditions, and the embodiments of the present application do not limit this.

[0159] For example, Figure 5bThe following illustrates another control information detection process. The first device configures three listening positions for the second device, which are recorded as MO1, MO2 and MO3. Different listening positions are associated with different TCIs, that is, different listening positions are associated with different beam directions. When the first device has no actual need for data scheduling, channel status information reporting and other instructions for the second device, it can send a second DCI to the second device to indicate that DCI detection is not required on multiple MOs this time. The first device first performs LBT on beam direction 1 and finds that the channel in this direction is occupied by other devices, resulting in LBT failure. Correspondingly, the second device does not detect the second DCI using the corresponding receiving beam on MO1. Then the first device performs LBT on beam direction 2 and finds that no other device occupies the channel in this direction, that is, LBT is successful. Then the first device can send the second DCI on MO2 using beam direction 2 associated with MO2. Correspondingly, the second device can detect the second DCI using the corresponding receiving beam on MO2. The first device subsequently no longer performs LBT on beam direction 3, that is, no longer sends the second DCI on MO3, and the second device no longer detects the second DCI on MO3.

[0160] Optionally, the start time of the second listening position is not earlier than that of the first listening position. That is, after the second device detects that the control information is successfully decoded at the first listening position, it will no longer (or stop or omit) detect the control information at other subsequent listening positions. Based on such a design, when the second device detects the control information, it can stop detecting the control information at other subsequent listening positions, which can reduce energy consumption.

[0161] In the embodiment of the present application, multiple listening positions for detecting control information are configured, and after the second device detects control information at one of the listening positions, it no longer detects control information at other listening positions, which can reduce energy consumption caused by detection at other listening positions.

[0162] In combination with Example 1 to Example 3, the following describes in detail the manner in which the first configuration information indicates the association between multiple listening positions, taking the example that the first configuration information includes the second configuration information and the third configuration information.

[0163] Example 1

[0164] (1) The first device may include configuration information of the first control resource set CORESET in the second configuration information.

[0165] Among them, the configuration information of the first CORESET may include some or all of the following contents: the duration of the first CORESET, for example, expressed by the number of symbols occupied by the first CORESET; at least two transmission configuration indications TCI; information used to indicate the frequency domain position corresponding to the first CORESET, for example, the first CORESET can correspond to one frequency domain position, or the first CORESET can also correspond to at least two frequency domain positions, and at least two frequency domain positions are associated one-to-one with at least two TCIs.

[0166] Specifically, the duration of the first CORESET and the frequency domain position corresponding to the first CORESET can be determined according to the control information capacity and / or channel environment that the first device hopes (or expects) to send.

[0167] The first device may determine at least two TCIs included in the configuration information of the first CORESET according to the beam training result between the first device and the second device. For example, the first device uses different transmission spatial domain filtering parameters (or transmission beams) to send different reference signals, and the second device measures these reference signals (such as source RS); the second device may also adjust its own receiving spatial domain filtering parameters (or reception beams) when measuring the reference signal, so as to determine which reception beam it uses under a specific transmission beam to obtain a larger channel gain. Optionally, the second device may report the index of at least one reference signal and its corresponding reference signal receiving power (RSRP) to the first device. For example, the second device reports at least one reference signal with a larger RSRP and the RSRP corresponding to the at least one reference signal to the first device, and the first device can know which transmission beams are used to send signals so that the second device can obtain a larger channel gain. Then the first device determines at least two TCIs according to the result of beam training, wherein each TCI may include a type-D QCLed RS, and the type-D QCLed RS in each TCI is a reference signal in the reference signal with a larger RSRP. The first device may include the at least two TCIs in the configuration information of the first CORESET.

[0168] Optionally, the first device may configure a first TCI list in the configuration information of the first CORESET, where the first TCI list includes the at least two TCIs mentioned above. Specifically, the first device may configure the first TCI list with reference to any one of the following methods A1 to A3.

[0169] A1, when configuring CORESET through high-level signaling, directly configure the first TCI list corresponding to the first COERSET.

[0170] A2, when configuring CORESET through high-level signaling, multiple TCI lists are configured, and then a TCI list in the multiple TCI lists is activated through MAC CE signaling as the first TCI list corresponding to the first COERSET. For example, Figure 6 The activation MAC CE format of the first TCI list is shown, and the MAC CE includes the following fields: the identification (ID) of the TCI list, the serving cell ID, and the CORESET ID (indicating the first CORESET). Specifically, Figure 6 It indicates that a TCI list may occupy 16 bits, of which the ID of the TCI list occupies 7 bits, the serving cell ID occupies 4 bits, and the CORESET ID occupies 4 bits.

[0171] A3, configure multiple TCIs when configuring CORESET through high-level signaling, and then configure the first TCI list through MAC CE signaling. The first TCI list includes the service cell ID, CORESET ID (indicating the first COERSET), and at least two TCI IDs, such as TCI ID1, TCI ID2, TCI ID3, etc.

[0172] (2) The first device may include configuration information of the first search space SS in the third configuration information.

[0173] Among them, the first SS is associated with the aforementioned first CORESET, and the configuration information of the first SS may include part or all of the following contents: information indicating the first CORESET, such as the ID of the first CORESET; cycle information of the first SS; information indicating multiple time offsets (offsets) within the same cycle of the first SS.

[0174] Specifically, among the multiple listening positions configured by the first device through the first configuration information, any one of the listening positions is associated with one of the multiple time offsets in the same cycle. For example, the multiple listening positions correspond to the multiple time offsets in the same cycle one by one, and the listening positions corresponding to the multiple time offsets in the same cycle of the first SS are associated.

[0175] Among the multiple time offsets within the same cycle of the first SS, any time offset is associated with one TCI of at least two TCIs corresponding to the first CORESET. The association relationship is used to indicate that when the first device sends control information at a listening position associated with a certain time offset, the control information has a QCL relationship with the reference signal (i.e., source RS) in the TCI associated with the time offset. Alternatively, the demodulation reference signal DMRS of the control information has a QCL relationship with the reference signal (i.e., source RS) in the TCI associated with the time offset.

[0176] Optionally, an offset list may be configured in the first SS, and the offset list may include multiple time offsets within the same period. In an optional implementation, the number of time offsets included in the offset list may be the same as the number of TCIs included in the first TCI list of the aforementioned first CORESET, and the association between the time offset and the TCI may correspond one to one according to the configuration order. In another optional implementation, the number of time offsets included in the offset list may be different from the number of TCIs included in the first TCI list of the aforementioned first CORESET, and the first device may indicate the association between the time offset and the TCI through additional configuration information. The configuration information may be included in the configuration information of the first SS, or it may be separate configuration information.

[0177] Specifically, the first device may configure multiple time offsets within the same period with reference to the following two optional implementations.

[0178] In an optional implementation, the time offset includes a time slot offset represented by an offset position in units of time slot numbers. For the same period in the first SS, multiple time slot offsets in the period may be represented by multiple offset position values ​​in units of time slot numbers. Specifically, the configuration information of the first SS may include the following fields:

[0179] Monitoring slot period and offset list (monitoringSlotPeriodicityAndOffsetList), the monitoring slot period and offset list field is used to indicate the period in time slots and multiple slot offsets in each period. The number of slot offsets in the same period can be the same as the number of TCIs included in the first TCI list of the first CORESET, and the association between the slot offset and the TCI can correspond one to one according to the configuration order.

[0180] Monitoring symbols within a time slot (monitoringSymbolsWithinSlot), the symbols within the monitoring time slot are used to indicate the starting detection symbol occupied by the first SS in a time slot when the time slot is the time slot where the first SS is located (such as the time slot corresponding to the aforementioned time slot offset). That is, it can be understood that the time position (such as the starting time position) configured by the first SS can be determined by the multiple time slot offsets contained in each cycle of the first SS and the starting detection symbol occupied by the first SS in the time slot. In addition, the number of time slots included in the first SS can be indicated by the duration field in the configuration information of the first CORESET.

[0181] In this manner, the first configuration information may indicate that the multiple listening positions are within the same cycle of the first SS, and the multiple listening positions may correspond one-to-one to the multiple time slot offsets within the same cycle. It can be understood that the multiple listening positions within the same cycle are associated with each other. The second device may reduce unnecessary blind detection overhead according to the relevant blind detection strategy.

[0182] For example, see Figure 7a , an embodiment of the present application provides a configuration method for a listening position. The configuration information of the first COREST includes a frequency domain position, the duration of the first CORSET, and two TCIs, namely TCI1 and TCI2. The duration of the first CORSET is two symbols. The configuration information of the first SS includes a period indication, each period includes 2 time slots, and each time slot includes 14 symbols. The listening time slot period and offset list include 2 time slot offsets, one of which is 0 time slots, and the corresponding starting listening symbol is the first symbol in the first time slot in the period (ie, symbol 0); the other time slot offset is 1 time slot, and the corresponding starting listening symbol is the first symbol in the second time slot in the period (ie, symbol 0). Of course, it can be understood that the starting listening symbols corresponding to different time slot offsets may be the same or different, and the embodiment of the present application does not limit this.

[0183] Figure 7a, two listening positions in the same cycle are specifically illustrated. For example, the first SS includes time slot 0 and time slot 1 in the first cycle, that is, it includes MO1 and MO3 in the first cycle; wherein the time slot offset associated with MO1 is 0, MO1 is associated with TCI1, and the corresponding starting listening symbol in time slot 0 is symbol 0; the time slot offset associated with MO3 is 1, MO3 is associated with TCI2, and the corresponding starting listening symbol in time slot 1 is symbol 0. MO1 and MO3 are two associated listening positions, and the second device can determine whether it is necessary to detect control information on MO3 based on the detection result of the control information detected on MO1. For another example, the first SS includes time slot 2 and time slot 3 in the second cycle, that is, it includes MO2 and MO4 in the second cycle; wherein the time slot offset associated with MO2 is 0, MO2 is associated with TCI1, and the corresponding starting listening symbol in time slot 2 is symbol 0; the time slot offset associated with MO4 is 1, MO4 is associated with TCI2, and the corresponding starting listening symbol in time slot 3 is symbol 0. MO2 and MO4 are two associated monitoring locations, and the second device can determine whether it is necessary to detect the control information on MO4 according to the detection result of detecting the control information on MO2.

[0184] In another optional implementation, the time offset can be determined by the time slot offset combined with the starting listening symbol in the time slot. For the same period in the first SS, a listening time slot indicated by the time slot offset can be included in the period, and the listening time slot refers to the time slot where the listening position exists. A bitmap is configured corresponding to the number of symbols included in the listening time slot, and the bitmap is used to indicate the position of the starting listening symbol in the listening time slot. For example, if the time slot includes 14 symbols, a bitmap including 14 bits is configured, and the xth bit in the bitmap corresponds to the xth symbol in the time slot. When the bit corresponding to a symbol in the bitmap is the first value, it indicates that the symbol is the starting listening symbol position in the time slot. The first value can be 1 or 0. Specifically, the configuration information of the first SS may include the following fields:

[0185] Monitoring Slot Period and Offset (monitoringSlotPeriodicityAndOffset), the monitoring slot period and offset list field is used to indicate a period in time slots and a time slot offset in each period;

[0186] Monitoring symbols within the time slot - listen before talking (monitoringSymbolsWithinSlot-LBT), the monitoring symbols within the time slot - listen before talking field indicates a bitmap, and the number of bits contained in the bitmap is the same as the number of symbols in the time slot indicated by the aforementioned time slot offset, for example, both are 14 or 12. When the corresponding bit on a symbol is 1 (or 0), it means that the symbol is the starting detection symbol in the time slot indicated by the aforementioned time slot offset. The number of starting monitoring symbols contained in the time slot can be the same as the number of TCIs contained in the first TCI list of the aforementioned first CORESET, and the association relationship between the starting monitoring symbol and the TCI can correspond one to one according to the configuration order.

[0187] In this manner, the first configuration information may indicate that the plurality of listening positions are in a listening time slot in the same cycle of the first SS, and the plurality of listening positions may correspond one to one with the plurality of starting listening symbols in the listening time slot. It can be understood that the plurality of listening positions in the same listening time slot are associated with each other, and the second device may reduce unnecessary blind detection overhead according to the relevant blind detection strategy.

[0188] For example, see Figure 7b , an embodiment of the present application provides another configuration method for the listening position. The configuration information of the first COREST includes a frequency domain position, the duration of the first CORSET, and two TCIs, namely TCI1 and TCI2. The duration of the first CORSET is two symbols. The configuration information of the first SS includes a period indication, each period includes 2 time slots and indicates that the time slot offset of the listening time slot is 0; each time slot includes 14 symbols. The 1st and 9th bits in the bitmap corresponding to the symbol in the detection time slot-listen first and speak later are configured to 1, that is, two starting listening symbols are configured in the listening time slot, one of which is the 1st symbol in the time slot (ie, symbol 0), and the other is the 9th symbol in the time slot (ie, symbol 8). Or it can be understood that each cycle includes two time offsets, and each time offset is determined by the time slot offset of the listening time slot and a starting listening symbol in the listening time slot. Specifically, one of the time offsets is determined by the time slot offset 0 and the symbol 0 in the time slot, and the other time offset is determined by the time slot offset 0 and the symbol 8 in the time slot.

[0189] Figure 7bIt is specifically illustrated that the listening time slot in each cycle includes two listening positions. For example, the listening time slot of the first SS in the first cycle (i.e., time slot 0) includes MO1 and MO3; wherein the starting listening symbol associated with MO1 is symbol 0, and MO1 is associated with TCI1; the starting listening symbol associated with MO3 is symbol 8, and MO3 is associated with TCI2. MO1 and MO3 are two associated listening positions, and the second device can determine whether it is necessary to detect the control information on MO3 by detecting the detection result of the control information on MO1. For another example, the listening time slot of the first SS in the second cycle (i.e., time slot 2) includes MO2 and MO4; wherein the starting listening symbol associated with MO2 is symbol 0, and MO2 is associated with TCI1; the starting listening symbol associated with MO4 is symbol 8, and MO4 is associated with TCI2. MO2 and MO4 are two associated listening positions, and the second device can determine whether it is necessary to detect the control information on MO4 by detecting the detection result of the control information on MO2.

[0190] Example 2:

[0191] (1) The access network device may include configuration information of the first control resource set CORESET in the second configuration information.

[0192] Specifically, it can be implemented with reference to (1) in Example 1, and the embodiments of the present application will not elaborate on this.

[0193] (2) The access network device may include configuration information of multiple second search spaces SS in the third configuration information.

[0194] The multiple second SSs are associated with the first CORESET, any one of the multiple second SSs is associated with one TCI of the at least two TCIs, and any one of the multiple listening positions is associated with one of the multiple second SSs.

[0195] Specifically, the configuration information of the second SS may include some or all of the following: information indicating the first CORESET, such as the ID of the first CORESET; second indication information (or TCI indication information), which is used for the TCI associated with the second SS in the first CORESET; period information of the second SS; time offset (in time slots) used to indicate the monitoring time slot in each period; and the starting monitoring symbol position in the monitoring time slot.

[0196] Optionally, the period information included by the multiple second SSs is the same, and the listening positions corresponding to the multiple second SSs in the same period are associated.

[0197] In addition, the access network device may also include information indicating the association between the multiple second SSs in the first configuration information. For example, the configuration information of each of the multiple second SSs also includes an association identifier, and the association identifiers in the configuration information of the multiple second SSs may be the same to indicate that the multiple second SSs with the same association identifier are associated, that is, the listening positions corresponding to the multiple second SSs are associated. For another example, the access network device may separately configure a third indication information in the first configuration information, and the third indication information is used to indicate that the multiple second SSs configured by the third configuration information are associated, or the third indication information may also directly indicate that the listening positions corresponding to the multiple second SSs in the same period are associated.

[0198] In this example, the first configuration information may indicate that the multiple listening positions are in the same period corresponding to the multiple second SSs, and the multiple listening positions may correspond one-to-one to the multiple time slot offsets in the same period. It can be understood that the multiple listening positions in the same period are associated with each other, and the terminal device can reduce unnecessary blind detection overhead according to the relevant blind detection strategy.

[0199] Example 3:

[0200] (1) The access network device includes configuration information of a plurality of second control resource sets CORESET in the second configuration information,

[0201] The configuration information of each second CORESET may include part or all of the following: the frequency domain position of the CORESET, the duration of the CORESET (for example, expressed in the number of symbols), the resource mapping method, and a transmission configuration indication TCI. The frequency domain positions of different second CORESETs may be the same or different.

[0202] (2) The access network device includes configuration information of multiple second search spaces SS in the third configuration information.

[0203] Any one of the plurality of second SSs is associated with one of the plurality of second CORESETs; and any one of the plurality of listening positions is associated with one of the plurality of second SSs.

[0204] Specifically, the configuration information of the second SS may include part or all of the following: information indicating the second CORESET associated with the second SS; period information of the second SS; a time offset (in time slots) used to indicate a monitoring time slot in each period; and a starting monitoring symbol position in the monitoring time slot.

[0205] In addition, the access network device may also include information indicating the association between the multiple second SSs in the first configuration information. For example, the configuration information of each of the multiple second SSs also includes an association identifier, and the association identifiers in the configuration information of the multiple second SSs may be the same to indicate that the multiple second SSs with the same association identifier are associated, that is, the listening positions corresponding to the multiple second SSs are associated. For another example, the access network device may separately configure a third indication information in the first configuration information, and the third indication information is used to indicate that the multiple second SSs configured by the third configuration information are associated, or the third indication information may also directly indicate that the listening positions corresponding to the multiple second SSs in the same period are associated.

[0206] In this example, the first configuration information may indicate that the multiple listening positions are in the same period corresponding to the multiple second SSs, and the multiple listening positions may correspond one-to-one to the multiple time slot offsets in the same period. It can be understood that the multiple listening positions in the same period are associated with each other, and the terminal device can reduce unnecessary blind detection overhead according to the relevant blind detection strategy.

[0207] For example, see Figure 8 , an embodiment of the present application provides a configuration method for a listening position. The first configuration information includes configuration information of two second CORSETs and configuration information of two second SSs. Among them, the configuration information of each second CORESET includes the frequency domain position of the second CORSET, the duration of the second CORSET and a TCI. The frequency domain positions of the two second CORESETs are different; the duration of the two second CORSETs is two symbols; the TCIs associated with the two second CORESETs are different. For example, in the two CORESETs, the configuration information of one CORESET includes TCI1, and the configuration information of the other CORESET includes TCI2. The configuration information of each second SS includes period indication information, each period includes 2 time slots, and each time slot includes 14 symbols. The configuration information of each second SS includes the starting listening symbol position in the listening time slot. For example, the configuration information of each second SS includes the time slot offsets of 2 monitoring time slots, one of which is 0 time slots, and the corresponding starting monitoring symbol is the first symbol in the first time slot in the cycle (i.e., symbol 0); the other time slot offset is 1 time slot, and the corresponding starting monitoring symbol is the first symbol in the second time slot in the cycle (i.e., symbol 0). Of course, it can be understood that the starting monitoring symbols corresponding to different time slot offsets can be the same or different, and the embodiments of the present application are not limited to this.

[0208] Figure 8 Two monitoring positions within the same cycle are specifically illustrated.

[0209] For example, the second SS includes time slot 0 and time slot 1 in the first cycle, that is, it includes MO1 and MO3 in the first cycle; wherein, the time slot offset associated with MO1 is 0, MO1 is associated with the second CORESET corresponding to TCI1, and the corresponding start monitoring symbol in time slot 0 is symbol 0. The time slot offset associated with MO3 is 1, MO3 is associated with the second CORESET corresponding to TCI2, and the corresponding start monitoring symbol in time slot 1 is symbol 0. The frequency domain position of the second CORESET corresponding to TCI1 is different from the frequency domain position of the second CORESET corresponding to TCI2, and the frequency domain positions of MO1 and MO3 are different. MO1 and MO3 are two associated monitoring positions, and the second device can determine whether it is necessary to detect control information on MO3 based on the detection result of detecting control information on MO1.

[0210] For another example, the second SS includes time slot 2 and time slot 3 in the second cycle, that is, MO2 and MO4 are included in the second cycle; wherein the time slot offset associated with MO2 is 0, MO2 is associated with the second COREST corresponding to TCI1, and the corresponding start monitoring symbol in time slot 2 is symbol 0. The time slot offset associated with MO4 is 1, MO4 is associated with the second CORESET corresponding to TCI2, and the corresponding start monitoring symbol in time slot 3 is symbol 0. The frequency domain position of the second CORESET corresponding to TCI1 is different from the frequency domain position of the second CORESET corresponding to TCI2, and the frequency domain positions of MO2 and MO4 are different. MO2 and MO4 are two associated monitoring positions, and the second device can determine whether it is necessary to detect control information on MO4 based on the detection result of detecting control information on MO2.

[0211] Fig. 9 An information transmission method is illustrated, which mainly includes the following process.

[0212] S901: A first device sends first configuration information to a second device.

[0213] The first configuration information is used to configure multiple listening positions and receiving spatial filtering parameter indication information (such as transmission configuration indication TCI) associated with each listening position in the multiple listening positions, and the multiple listening positions are used to detect control information. The second device can determine multiple listening positions according to the first configuration information. Specifically, it can be implemented with reference to S401, and this embodiment of the present application will not be repeated here.

[0214] Specifically, the first device may be an access network device, and the second device may be a terminal device. Exemplarily, the control information may be downlink control information DCI.

[0215] Taking the example that the first configuration information includes the second configuration information and the third configuration information, the manner in which the first configuration information indicates the association between multiple listening positions can also be implemented with reference to Examples 1 to 3 described above, and this embodiment of the present application will not be described in detail.

[0216] S902: The second device detects first indication information in the control information through the first listening position, and determines whether to detect the control information through the second listening position according to the detection result.

[0217] The plurality of monitoring positions include the first monitoring position, for example, the first monitoring position is any one of the plurality of monitoring positions. The second monitoring position is any one of the plurality of monitoring positions except the first monitoring position.

[0218] Specifically, the first indication information is used to indicate whether to detect the control information through the second listening position or not. For the second device, if the second device detects the first indication information through the first listening position, it determines whether to detect the control information through the second listening position according to the first indication information. Specifically, for example, the first indication information is used to indicate that the control information is detected through the second listening position, then when the second device detects the first indication information at the first listening position, it can continue to detect the control information through the second listening position. For another example, the first indication information is used to indicate that the control information is not detected through the second listening position, then when the second device detects the first indication information at the first listening position, it will no longer detect the control information through the second listening position. In addition, if the second device does not detect the first indication information through the first listening position, it can also detect the control information through the second listening position.

[0219] Optionally, the start time of the second listening position is not earlier than that of the first listening position. It can be understood that the first indication information in the aforementioned control information can also specifically indicate whether to detect the control information through other subsequent listening positions. For example, the second device detects the control information at the first listening position, and the first indication information in the control information indicates that the control information is not detected through other subsequent listening positions. Then, after successfully decoding the control information, the second device will no longer (or stop, omit) detect the control information at other subsequent listening positions. Based on such a design, when the second device detects the control information, it can stop detecting the control information at other subsequent listening positions, which can reduce energy consumption.

[0220] For example, Fig.10The following illustrates a control information detection process. The first device configures three listening positions for the second device, which are recorded as MO1, MO2 and MO3. Different listening positions are associated with different TCIs, that is, different listening positions are associated with different transmission beam directions. When the first device has control information (including the first indication information) to send to the second device, the first device first performs LBT on beam direction 1, and finds that the channel in this direction is occupied by other devices, resulting in LBT failure. Correspondingly, the second device does not detect the first indication information in the control information on MO1, and then the second device performs LBT on beam direction 2, and finds that no other device occupies the channel in this direction, that is, LBT is successful. Then the first device can send control information on MO2 using beam direction 2 associated with MO2, and the first device has no additional control information to send on MO3, so the first indication information in the control information sent by the first device in beam direction 2 indicates that the control information is not detected through subsequent other listening positions. Correspondingly, the first device will no longer perform LBT on beam direction 3 or send control information on MO3. After the second device detects the first indication information in the control information on MO2, it no longer detects the control information on MO3.

[0221] In an embodiment of the present application, the first device instructs the second device on a blind detection strategy at multiple listening positions through the first indication information, thereby reducing unnecessary blind detection overhead on the second device side.

[0222] See also Fig.11 An information transmission method is illustrated, which mainly includes the following process.

[0223] S1101. A first device sends first configuration information to a second device.

[0224] The first configuration information is used to configure multiple listening positions and receiving spatial filtering parameter indication information (such as transmission configuration indication TCI) associated with each listening position in the multiple listening positions, and the multiple listening positions are used to detect control information. In addition, it can be understood that the listening position can also be called a monitor occasion (MO) or other name, which is not limited in the embodiment of the present application.

[0225] Specifically, multiple listening positions are associated with the same TCI. Or it can be understood that in S1101, the first device configures multiple listening positions in the transmission beam direction corresponding to the same transmission spatial domain filtering parameter. If the first device sends control information at multiple listening positions, the transmission spatial domain filtering parameters used at the multiple listening positions are the same. Correspondingly, the receiving spatial domain filtering parameters used by the second device for blind detection at multiple listening positions are also the same. Optionally, the first device may be an access network device, and the second device may be a terminal device. Exemplarily, the aforementioned control information may be downlink control information DCI.

[0226] Specifically, the first configuration information may include indication information of multiple listening positions, directly indicating the time-frequency position corresponding to each listening position. Alternatively, the first configuration information includes second configuration information and third configuration information, the second configuration information is used to configure the frequency domain positions of the multiple listening positions, and the third configuration information is used to configure the time domain positions of the multiple listening positions; or, the configuration information of the listening position (such as identification, time-frequency position, etc.) can be pre-deployed on the second device side, and the first device includes identifications of multiple listening positions in the first configuration information, then the second device determines the multiple listening positions according to the identifications of the multiple listening positions included in the first configuration information.

[0227] Optionally, the multiple listening positions configured by the first configuration information are associated. The second device can determine multiple associated listening positions according to the first configuration information. Alternatively, it can be understood that the first configuration information can also be used to indicate the association between the aforementioned multiple listening positions.

[0228] Optionally, the multiple monitoring positions are as close as possible in time, for example, the time positions of the multiple monitoring positions may be within the same preconfigured period range.

[0229] Exemplarily, the first configuration information includes second configuration information and third configuration information, wherein the second configuration information includes configuration information of a second control resource set CORESET, and the configuration information of the second CORESET includes a TCI. The third configuration information includes configuration information of a third search space SS, and the configuration information of the third SS includes information indicating multiple time offsets within the same period, and the multiple time offsets within the same period are associated with the same TCI, and the same TCI can be the TCI included in the configuration information of the aforementioned second CORESET. Any one of the multiple listening positions is associated with one of the multiple time offsets within the same period, and the listening positions corresponding to the multiple time offsets within the same period are associated.

[0230] Exemplarily, the first configuration information includes second configuration information and third configuration information, wherein the second configuration information includes configuration information of a second control resource set CORESET, and the configuration information of the second CORESET includes a TCI. The third configuration information includes configuration information of multiple fourth search spaces SS, and the configuration information of each fourth SS includes time offset and period information; the first configuration information also includes information indicating the association between the multiple fourth SSs, and the multiple fourth SSs are associated with the same TCI, and the same TCI can be the TCI included in the configuration information of the aforementioned second CORESET; any one of the multiple listening positions is associated with one of the multiple fourth SSs; the multiple fourth SSs include the same period information, and the listening positions corresponding to the multiple fourth SSs in the same period are associated. Further, the first device can also set the first listening position among the multiple listening positions as a listening position for sending the first information, and the first information can be used to indicate the detection of control information through multiple listening positions. It can be understood that the first listening position is a predetermined listening position among the multiple listening positions. The first device may determine any one of the multiple listening positions as the first listening position; or, the first device may also determine a listening position that is earlier in time among the multiple listening positions as the first listening position, for example, the second listening position is recorded as any one of the multiple listening positions except the first listening position, then the starting time of the second listening position is not earlier than the first listening position. It should also be noted that the first listening position may also be understood as the main listening position, and the second listening position may also be understood as the auxiliary listening position. Of course, the first listening position may also be referred to as other names, and the second listening position may also be referred to as other names, and the embodiments of the present application do not limit this.

[0231] Optionally, the first device may also indicate information of the first listening position in the first configuration information. For example, the first device may specifically configure information indicating the first listening position separately in the first configuration information. Alternatively, the first device may add a relevant identifier to the configuration information of the fourth SS associated with the first listening position, so as to indicate through the relevant identifier that the listening position associated with the fourth SS is a predetermined listening position, i.e., the first listening position. Thus, the second device knows that it is necessary to detect the first information at the first listening position when the first configuration information is obtained.

[0232] S1102: The second device detects first information through a first listening position, and determines whether to detect control information through a second listening position according to the detection result.

[0233] Exemplarily, when the first device performs LBT in a transmission beam direction, if LBT is successful and the first device needs to send control information in the transmission beam direction, the first information can be sent at the first listening position. If the second device detects the first information at the first listening position, it can be determined that the first device needs to send control information in the transmission beam direction, and the second device can detect the control information at other listening positions corresponding to the transmission beam direction; if the first device performs LBT in the beam direction successfully but the first device does not need to send control information in the transmission beam direction, or the first device fails in LBT in the beam direction, the first device will not send the first information at the first listening position, and the second device will not detect the first information at the first listening position. If the second device does not detect the first information at the first listening position, it can be determined that the first device does not need to detect the control information at other listening positions corresponding to the transmission beam direction.

[0234] Specifically, taking the second listening position as any one of the multiple listening positions except the first listening position as an example, if the second device detects the first information through the first listening position, the control information is detected through the second listening position; or, if the second device does not detect the first information through the first listening position, the control information is not detected through the second listening position.

[0235] For example, Fig.12 The first device configures multiple listening positions for the second device in the same beam direction. Fig.12 MO1 and MO2 are shown in the figure. MO1 is a predetermined listening position, and the start time of MO2 is no earlier than that of MO1. When the LBT performed by the first device in the beam direction fails or the LBT performed by the first device in the beam direction succeeds but the first information is not sent on MO1, the second device will not detect the first information on MO1. In addition, the first device does not send any information on MO2, and the second device will not detect the control information on MO2.

[0236] In the embodiment of the present application, multiple listening positions for detecting control information are configured for the same beam direction, and the first device indicates the detection strategy of the second device at the multiple listening positions through the first information, which can reduce unnecessary blind detection overhead on the second device side.

[0237] The above describes the method provided by the embodiment of the present application from the perspective of the interaction between the first device and the second device. In order to implement the functions in the above method, the first device and the second device may include a hardware structure and / or a software module, and implement the above functions in the form of a hardware structure, a software module, or a hardware structure plus a software module. Whether a function of the above functions is executed in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.

[0238] Based on the same idea, see Fig.13 , the embodiment of the present application provides a communication device 1300, which includes a processing module 1301 and a communication module 1302. The communication device 1300 can be a first device (such as an access network device), or a communication device applied to the first device or used in combination with the first device, and capable of implementing a communication method executed on the first device side; or, the communication device 1300 can be a second device (such as a terminal device), or a communication device applied to the second device or used in combination with the second device, and capable of implementing a communication method executed on the second device side.

[0239] Among them, the communication module may also be referred to as a transceiver module, a transceiver, a transceiver, a transceiver device, etc. The processing module may also be referred to as a processor, a processing board, a processing unit, a processing device, etc. Optionally, the device used to implement the receiving function in the communication module may be regarded as a receiving unit. It should be understood that the communication module is used to perform the sending operation and the receiving operation on the access network device side or the terminal device side in the above method embodiment, and the device used to implement the sending function in the communication module is regarded as a sending unit, that is, the communication module includes a receiving unit and a sending unit.

[0240] Take the first device as an access network device and the second device as a terminal device as an example: when the communication device 1300 is applied to the terminal device, the receiving unit included in its communication module 1302 is used to perform a receiving operation on the terminal device side, such as receiving a downlink signal from the access network device. The sending unit included in its communication module 1302 is used to perform a sending operation on the terminal device side, such as sending an uplink signal to the access network device. When the communication device 1300 is applied to the access network device, the receiving unit included in its communication module 1302 is used to perform a receiving operation on the access network device side, such as receiving an uplink signal from the terminal device; the sending unit included in its communication module 1302 is used to perform a sending operation on the access network device side, such as sending a downlink signal to the terminal device. In addition, it should be noted that if the device is implemented using a chip / chip circuit, the communication module can be an input-output circuit and / or a communication interface to perform an input operation (corresponding to the aforementioned receiving operation) and an output operation (corresponding to the aforementioned sending operation); the processing module is an integrated processor or microprocessor or integrated circuit.

[0241] In combination with the first mode and the second mode, the implementation mode of applying the communication device 1300 to the second device (such as a terminal device) is described in detail below.

[0242] In the first embodiment, the communication device 1300 includes:

[0243] The communication module 1302 is configured to obtain first configuration information, where the first configuration information is used to configure a plurality of listening positions and receiving spatial domain filtering parameter indication information associated with each of the plurality of listening positions, where the plurality of listening positions are used to detect control information; and at least two of the plurality of listening positions are associated with different receiving spatial domain filtering parameter indication information;

[0244] The processing module 1301 is used to detect control information through a first listening position, and determine whether to detect the control information through a second listening position based on the detection result; wherein the multiple listening positions include the first listening position, and the second listening position is any one of the multiple listening positions except the first listening position.

[0245] In an optional implementation of the first manner, a start time of the second monitoring position is no earlier than a start time of the first monitoring position.

[0246] In an optional implementation of the first method, the processing module 1301 is specifically used to: if the control information is detected through the first listening position, then the control information is not detected through the second listening position; or if the control information is not detected through the first listening position, then the control information is detected through the second listening position.

[0247] In an optional implementation of the first method, the processing module 1301 is specifically used to: detect first indication information in the control information through the first listening position, and the first indication information is used to indicate whether to detect the control information through the second listening position or not to detect the control information through the second listening position.

[0248] In an optional implementation of the first manner, the first monitoring position is any one of a plurality of monitoring positions.

[0249] In an optional implementation of the first manner, the multiple monitoring positions are associated.
