The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment.

[0049] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0050] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0051] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0052] As an example and not a limitation, in an embodiment of the present application, the network device may have a mobile feature, for example, the network device may be a mobile device. In some embodiments of the present application, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of the present application, the network device may also be a base station set up in a location such as land or water.

[0053] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0054] For example, Figure 1A is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 1A, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or also referred to as a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices located within the coverage area.

[0055] Figure 1A exemplarily shows a network device and two terminal devices. In some embodiments of the present application, the communication system 100 may include multiple network devices and each network device may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0056] For example, FIG1B is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1B , a terminal device 1101 and a satellite 1102 are included, and wireless communication can be performed between the terminal device 1101 and the satellite 1102. The network formed between the terminal device 1101 and the satellite 1102 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1B , the satellite 1102 can have the function of a base station, and the terminal device 1101 and the satellite 1102 can communicate directly. In the system architecture, the satellite 1102 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0057] For example, FIG1C is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1C , it includes a terminal device 1201, a satellite 1202, and a base station 1203. Wireless communication can be performed between the terminal device 1201 and the satellite 1202, and communication can be performed between the satellite 1202 and the base station 1203. The network formed between the terminal device 1201, the satellite 1202, and the base station 1203 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1C , the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be transferred through the satellite 1202. In this system architecture, the base station 1203 can be referred to as a network device. In some embodiments of the present application, a plurality of network devices 1203 may be included in the communication system, and each network device 1203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0058] It should be noted that Figures 1A-1C are only examples of the system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems, such as 5G communication systems, LTE communication systems, etc., and the embodiment of this application does not make specific limitations on this.

[0059] In some embodiments of the present application, the wireless communication system shown in Figures 1A-1C may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but the embodiments of the present application are not limited to this.

[0060] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1A as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0061] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0062] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0063] The “configuration” in the embodiment of the present application may include configuration through at least one of system messages, radio resource control (RRC) signaling and media access control element (MAC CE).

[0064] In some embodiments of the present application, "predefined" or "preset" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). This application does not limit the specific implementation method. For example, predefined may refer to information defined in a protocol.

[0065] In some embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0066] The Third Generation Partnership Project (3GPP) is currently researching NTN technology. NTN typically uses satellite communications to provide communication services to terrestrial users. Compared to terrestrial cellular networks, satellite communications offer many unique advantages.

[0067] First, satellite communications are not restricted by user geography. For example, conventional terrestrial communication networks cannot cover areas where network equipment cannot be deployed, such as oceans, mountains, and deserts. Similarly, terrestrial communication networks do not cover certain sparsely populated areas. However, because satellite communications can cover a large ground area and orbit the Earth, theoretically, every corner of the Earth can be covered by a satellite communication network.

[0068] Secondly, satellite communications have significant social value. They can provide low-cost coverage to remote, mountainous areas and impoverished countries and regions, enabling people in these areas to enjoy advanced voice communications and mobile internet technologies. From this perspective, satellite communications help narrow the digital divide with developed regions and promote their development.

[0069] Again, satellite communication has the advantage of long distance, and the increase in communication distance does not significantly increase the cost of communication.

[0070] Finally, satellite communications are highly stable and not affected by natural disasters.

[0071] Communication satellites are classified according to their orbital altitude into low Earth orbit (LEO), medium Earth orbit (MEO), geostationary Earth orbit (GEO), and high elliptical orbit (HEO). Currently, research focuses on LEO and GEO satellites.

[0072] LEO satellites typically operate at altitudes between 500 and 1500 km. Accordingly, their orbital period is approximately 1.5 to 2 hours. For LEO satellites, the signal propagation delay for single-hop communication between users is typically less than 20 milliseconds. The maximum satellite visibility time for LEO satellites is approximately 20 minutes. LEO satellites offer advantages such as short signal propagation distances, low link loss, and low transmit power requirements for user devices.

[0073] GEO satellites orbit at an altitude of 35,786 km. They orbit the Earth every 24 hours. For GEO satellites, the signal propagation delay for single-hop communication between users is typically about 250 milliseconds.

[0074] To ensure satellite coverage and increase the capacity of the entire satellite communication system, satellites typically use multiple beams to cover the ground. Therefore, a single satellite can form dozens or even hundreds of beams to cover the ground. A single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0075] Currently, the NTN system includes the NR-NTN system and the Internet of Things (IoT)-NTN system.

[0076] Currently, 3GPP is considering two types of satellites: those with transparent payloads and those with regenerative payloads. The following describes the network architectures for satellites with transparent payloads and those with regenerative payloads, respectively, using Figures 2 through 4.

[0077] In the satellite network architecture shown in Figures 2 to 4, the satellite network architecture may include a terminal device 210, a satellite node 222, and a ground receiving station 221 (referred to as a "ground station"). Wireless communication exists between the terminal device 210 and the satellite node 222. The terminal device 210 can send data to the satellite node 222 via the link between the terminal device 210 and the satellite node 222. For example, data can be sent to the satellite node 222 via a service link. Accordingly, after receiving the data, the satellite node 222 can send the data to the ground receiving station 221 via the link between the satellite node 222 and the ground receiving station 221. For example, the data can be transmitted to the ground receiving station 221 via a wireless link (such as a feeder link). Accordingly, after receiving the data from the satellite node 222, the ground receiving station 221 transmits the data to the core network (data network), which then processes the data via the core network, such as for data exchange with other terminals. It can be understood that the service link here refers to the link between the terminal device 210 and the satellite node 222, and the feeder link refers to the link between the satellite node 222 and the ground receiving station 221. In other possible embodiments, the link between the terminal device and the satellite node, and / or the link between the satellite node and the ground receiving station can also be expressed by other terms, which are not limited in this application.

[0078] The above-mentioned satellite nodes 222 can be divided into three types. The first type of satellite node is only used for forwarding, that is, it only has a transparent forwarding function. In some implementations, such satellite nodes may only provide one or more of a radio frequency filtering function, a frequency conversion function, and a power amplification function. For this type of satellite node, the received terminal device signal is amplified and then sent to the ground receiving station without any processing on the satellite node, as shown in Figure 2; wherein, the terminal device and the satellite node can communicate through the NR-Uu interface, the satellite node and the ground receiving station (such as the NTN radio frequency remote unit (RRU) and gNB) can communicate through the NR-Uu interface, the ground receiving station and the 5G core network (5G CN) can communicate through the N1 / 2 / 3 interface, and the 5G CN and the data network can communicate through the N6 interface.

[0079] The second type of satellite node has complete base station processing functions. The satellite node is a base station for the terminal equipment on the ground. The communication between the satellite node and the terminal equipment is basically the same as normal 5G communication, as shown in Figure 3. In some implementations, such satellite nodes can also provide one or more of the following functions: demodulation function, decoding function, routing function, conversion function, encoding function, and modulation function. Among them, the terminal equipment and the satellite node can communicate through the NR-Uu interface, and the satellite node and the ground receiving station can communicate through the satellite radio interface (SRI). The SRI interface can be used to send interface messages between the satellite node and the 5G CN (such as N2 / N3 interface messages). The ground receiving station and the 5G CN can communicate through the N1 / 2 / 3 interface, and the 5G CN and the data network can communicate through the N6 interface.

[0080] The third type of satellite node has DU processing capabilities. To ground-based terminal devices, the satellite node appears as a DU. Communication between the satellite node and terminal devices is essentially the same as that between terminal devices and DUs in a normal 5G terrestrial communication system, as shown in Figure 4. Terminal devices and satellite nodes can communicate via the NR-Uu interface, while satellite nodes and ground receiving stations (such as gNB-CUs) can communicate via the SRI interface, which transmits F1 interface messages between the satellite and ground receiving stations. Ground receiving stations and 5G CNs can communicate via the N1 / 2 / 3 interfaces, and the 5G CN and data networks can communicate via the N6 interface.

[0081] In satellite communications, satellites may have limited transmission power and processing bandwidth, depending on their deployment and the NTN system's requirements for the physical channel signal-to-noise ratio (SNR) of terminal devices. Consequently, a satellite may only be able to serve a portion of its coverage area at a time. In other words, due to limited power and feeder link bandwidth, a satellite may not be able to keep all beams active at the same time and ensure that each beam meets the nominal equivalent isotropic radiated power (EIRP) density. Consequently, related technologies have proposed the use of beam hopping in the downlink.

[0082] Figure 5 shows an example of the beam hopping implementation process. Referring to Figure 5, the satellite serves a group of beams at time t0 (i.e., beam 1, beam 2, and beam 3 in Figure 5, and each beam in the group of beams can be called an activated beam or an activated satellite beam). The coverage area of ​​each beam in the group of beams on the earth can be regarded as a cell. Therefore, multiple activated beams can correspond to multiple activated cells. Then, at time t1, the group of beams will become inactive, at which time the satellite can activate another group of beams (i.e., beam 1', beam 2', and beam 3' in Figure 5). The above process is the beam hopping process in a multi-beam system. As can be seen from the above description, the beam hopping process will cause the cell to switch from an active state to an inactive state.

[0083] In a beam hopping scenario, network devices may need a flexible way to control beam activation / deactivation. To address this issue, the following describes an embodiment of the present application in detail.

[0084] Figure 6 is a schematic flow chart of a wireless communication method provided in an embodiment of the present application. The method of Figure 6 can be performed by a terminal device. The terminal device can, for example, be an NTN-enabled terminal device. It should be understood that the embodiments of the present application do not specifically limit the state of the terminal device; the terminal device can be in a connected state, an idle state, or an inactive state.

[0085] 6 , in step S610 , the terminal device receives first downlink signaling, which is used to indicate beam information (or activated beam information). The beam information includes one or more of the following: an activated target beam and a valid duration of the target beam.

[0086] It should be understood that an activated target beam may also be referred to as an active beam or an activated beam direction. The target beam may include one beam or multiple beams. "Active" may also be referred to as or replaced by "valid" or "usable." It should also be understood that the effective time of a target beam refers to the time during which the target beam is in an activated, valid, or usable state. The target beam mentioned here may be a cell-level beam. For example, one cell may correspond to one beam.

[0087] The first downlink signaling may be dynamic signaling. For example, the first downlink signaling may be downlink control information (DCI). In another example, the first downlink signaling may be MAC CE.

[0088] In some implementations, the effective time of the target beam can be determined based on the transmission time of the first downlink signaling (such as the time when the terminal device receives the first downlink signaling) and / or the offset (which can be in symbols or time slots). For example, the reference time can be first determined based on the transmission time of the first downlink signaling, and then the offset can be added to the reference time to determine the starting time of the effective time of the target beam. The reference time can be, for example, the starting time or the ending time of the transmission time of the first downlink signaling, or the starting time or the ending time of the time slot in which the first downlink signaling is located.

[0089] In some implementations, the offset may be determined based on one or more of the following: terminal device capabilities, predefined information, and network device configuration information. The predefined information may, for example, be one or more predefined values ​​that may correspond to a subcarrier spacing.

[0090] In some implementations, the value of the validity period may belong to a set of candidate values. The set of candidate values ​​may be determined based on configuration information of the network device. For example, the network device may configure the set of candidate values ​​based on RRC signaling and / or MAC CE.

[0091] In some implementations, the value of the valid time may be in units of time slots or symbols.

[0092] After receiving the first downlink signaling, in some implementations, the terminal device may determine an activated target beam and then adjust transmission and / or reception operations according to the target beam.

[0093] The following describes in detail the implementation of the first downlink signaling by taking the first downlink signaling being DCI and MAC CE as examples.

[0094] Implementation method 1: the first downlink signaling is the first DCI (or the first DCI format)

[0095] The first DCI may indicate the index of the target beam in the activated state. The index of the target beam may be associated with a synchronization signal block (SSB) index or a channel state information reference signal (CSI-RS) resource index. Taking frequency range 1 (FR1) as an example, there are 4 SSB indexes in FR1, namely SSB0 to SSB3. The first DCI format may include a 4-bit indication field. The indication field may indicate the target beam using a bitmap. Exemplarily, as shown in FIG7 , the 4 bits (represented by B0, B1, B2, and B3, respectively) correspond to 4 SSB indexes, wherein the most significant bit (MSB) of the 4 bits represents the minimum value of the SSB index, and the least significant bit (LSB) of the 4 bits represents the maximum value of the SSB index. If the value of a bit in the 4 bits is "1", it indicates "activated"; if the value of a bit in the 4 bits is "0", it indicates "inactivated". In the example on the left side of Figure 7, the bits corresponding to SSB0 and SSB2 are 1, and the bits corresponding to SSB1 and SSB3 are 0. Therefore, according to the indication of the bitmap, the terminal device can determine that during the valid time, the beams associated with SSB0 and SSB2 are in an activated state, and the remaining beams are in an inactivated state. In the example on the right side of Figure 7, only the bit corresponding to SSB2 is 1, and the bits corresponding to SSB0, SSB1, and SSB3 are all 0. Therefore, according to the indication of the bitmap, the terminal device can determine that during the valid time, the beam associated with SSB2 is in an activated state, and the remaining beams are in an inactivated state. It is worth noting that the number of bits in the bitmap can be determined based on the frequency domain range or spectrum access mode in addition to the total number of SSB indices.

[0096] In addition to indicating the active target beam, the first DCI may also indicate the validity period of the target beam. For example, the first DCI may include an indication field for indicating the validity period. The indication field indicates a value for the validity period from a set of candidate values. The candidate values ​​for the validity period may be determined based on configuration information of the network device. For example, the network device may configure the candidate values ​​for the validity period based on RRC signaling and / or MAC CE. Furthermore, the value of the validity period may be in units of time slots or symbols.

[0097] In some implementations, the first DCI is a DCI specific to the terminal device.

[0098] In some implementations, the first DCI is a group-common DCI. Alternatively, the PDCCH carrying the first DCI is a group-common PDCCH. Alternatively, the PDCCH carrying the first DCI is transmitted based on a type 3 common search space.

[0099] In some implementations, the first DCI is scrambled based on a dedicated RNTI.

[0100] In some implementations, the first DCI may include one or more information fields. The one or more information fields may correspond one-to-one to one or more cells. Each of the one or more information fields may be used to indicate beam information of the cell corresponding to each information field (which may include the activated beam and / or the effective time of the activated beam of the cell corresponding to each information field).

[0101] For example, referring to FIG8 , if a terminal device is associated with cell X, the network device may configure the terminal device to monitor the first DCI and provide the terminal device with the first bit position of block n (which may include N bits, where N is a positive integer greater than or equal to 1). After receiving the first DCI, the terminal device may read N bits starting from the first bit position of block n (the number of bits contained in different blocks may be the same) to obtain the beam information of cell X.

[0102] The embodiments of the present application do not specifically limit the monitoring method of the first DCI. For example, the terminal device can monitor the first DCI through multiple monitoring occasions (MO). Furthermore, in some implementations, the multiple monitoring occasions are associated with multiple transmission configuration indication (TCI) states. For example, the multiple monitoring occasions include a first monitoring occasion and a second monitoring occasion, the first monitoring occasion is associated with a first TCI state, and the second monitoring occasion is associated with a second TCI state.

[0103] In some implementations, the symbols corresponding to the multiple listening opportunities are consecutive symbols, as shown in FIG9A .

[0104] In some implementations, the time slots corresponding to the multiple listening opportunities may be consecutive time slots, as shown in FIG9B .

[0105] The following is a detailed example of how to determine the starting time of the effective time.

[0106] In some implementations, the starting moment of the valid time can be determined based on one or more of the following: the transmission time of the first DCI (such as the time when the terminal device receives the first DCI), and the first offset.

[0107] For example, the start time of the valid time is determined based on the sum of the end time of the transmission time of the first DCI and the first offset. Exemplarily, the start time of the valid time is the time corresponding to the sum of the end time of the transmission time of the first DCI and the first offset (see (a) in Figure 10). In this case, the first offset can be in symbols.

[0108] For another example, the starting time of the valid time is determined based on the sum of the starting time of the transmission time of the first DCI and the first offset. Exemplarily, the starting time of the valid time is the time corresponding to the sum of the starting time of the transmission time of the first DCI and the first offset. In this case, the first offset can be in time slots or in symbols.

[0109] In some implementations, the start time of the valid time is determined based on the first time slot and / or the first offset. The first time slot is determined based on the transmission time of the first DCI. For example, the first time slot corresponds to the transmission time of the first DCI, that is, the transmission time of the first DCI is within the first time slot.

[0110] For example, the start time of the effective time is determined based on the sum of the end time of the first time slot and the first offset. Exemplarily, the start time of the effective time is the time corresponding to the sum of the end time of the first time slot and the first offset, see (b) in Figure 10.

[0111] For another example, the start time of the effective time is determined based on the sum of the start time of the first time slot and the first offset. For example, the start time of the effective time is the time corresponding to the sum of the start time of the first time slot and the first offset, see (c) in Figure 10.

[0112] If the starting moment of the valid time is determined based on the first time slot and the first offset, in some implementations, the first offset may be in units of time slots.

[0113] There are various ways to determine the value of the first offset. For example, the value of the first offset can be determined based on one of the following: terminal device capabilities, a predefined value, and network device configuration information. The predefined value can correspond to the subcarrier spacing.

[0114] Implementation method 2: The first downlink signaling is the first MAC CE

[0115] In some implementations, if the first downlink signaling is the first MAC CE, the target beam in the beam information can be represented in a manner similar to implementation method one (such as based on a bit map representation), or the target beam in the beam information can also be represented by an SSB index or a CSI-RS resource identifier.

[0116] In some implementations, if the first downlink signaling is a first MAC CE, the first MAC CE may indicate, in addition to the beam information mentioned above, one or more of a cell identifier and / or a bandwidth part (BWP) identifier.

[0117] If the first downlink signaling is a first MAC CE, the start time of the effective time of the target beam may be related to the transmission and / or feedback of the first MAC CE. The following describes in detail the method for determining the start time of the effective time of the target beam with examples.

[0118] In some implementations, the starting moment of the effective time of the target beam can be determined based on one or more of the following: the transmission time of the first MAC CE (such as the time when the terminal device receives the first MAC CE), the transmission time of the feedback information of the first MAC CE (hybrid automatic repeat reQuest-acknowledgement (HARQ-ACK) information) (such as the time when the terminal device sends the feedback information), and a second offset.

[0119] Example 1 (applicable to the scenario where the terminal device sends feedback information corresponding to the first MAC CE):

[0120] The starting moment of the effective time of the target beam is determined based on the first downlink time slot and / or the second offset (which can be determined based on system information). The first downlink time slot can be determined based on the first uplink time slot (for example, the first downlink time slot corresponds to the time slot number of the first uplink time slot, that is, the first downlink time slot has the same time slot number as the first uplink time slot). The first uplink time slot corresponds to the transmission time of the feedback information, that is, the transmission time of the feedback information is in the first uplink time slot (the terminal device sends the feedback information in the first uplink time slot).

[0121] Furthermore, in some implementations, the start time of the effective time of the target beam is determined based on the sum of the first downlink timeslot and the second offset. For example, referring to FIG11 , the start time of the effective time of the target beam begins at the first downlink timeslot n+3ms+K_mac, where K_mac is the second offset and can be one or more timeslots provided by the system information.

[0122] Example 2 (applicable to a scenario where the terminal device sends or does not send feedback information corresponding to the first MAC CE):

[0123] The starting time of the effective time of the target beam is determined based on the second downlink time slot and / or the second offset. The second downlink time slot corresponds to the transmission time of the first MAC CE, that is, the first MAC CE is transmitted in the second downlink time slot (the terminal device receives the first MAC CE in the second downlink time slot).

[0124] For example, referring to FIG12 , the start time of the effective time of the target beam is determined based on the sum of the second downlink time slot and the second offset. Exemplarily, the start time of the effective time of the target beam is equal to the time corresponding to the sum of the second downlink time slot (which can be calculated from the start time of the second downlink time slot or the end time of the second downlink time slot) and the second offset.

[0125] In Example 2, the second offset can be determined based on one or more of predefined information, configuration information of the network device, and capabilities of the terminal device.

[0126] The above describes in detail the implementation of the first downlink signaling. The embodiment of the present application does not specifically limit the behavior of the terminal device after receiving the first downlink signaling. The following describes in detail the possible impact of the introduction of the first downlink signaling on the behavior of the terminal device.

[0127] About PDCCH monitoring in CORESET

[0128] The terminal device can be configured with one or more CORESETs (including CORESET0). One of the CORESETs can be configured with one or more TCI states. The TCI state may include quasi co-location (QCL) information. The QCL information may include an SSB index or a CSI-RS resource index. If there are two downlink transmissions and the terminal device can receive the two downlink transmissions using the same spatial filter, the two downlink transmissions may be said to be quasi co-located. In some implementations, the TCI state may be associated with a beam. For example, the TCI state may be associated with an SSB index or a CSI-RS resource index. Therefore, if a CORESET is configured with a TCI state, and the TCI state is associated with a type of beam information, it means that the CORESET is configured with the beam information associated with the TCI state; accordingly, the terminal device knows what kind of spatial filter to use to receive the PDCCH in the CORESET. If a CORESET is configured with multiple TCI states, and the multiple TCI states are associated with multiple beam information, it means that the CORESET is configured with multiple beam information associated with the multiple TCI states. Therefore, the terminal device can use different beam directions (or different air filters) to receive the PDCCH in the CORESET.

[0129] Therefore, in some implementations, the terminal device may determine whether to monitor the PDCCH in the first CORESET within the valid time based on the TCI state and / or target beam configured for the first CORESET (which may be any CORESET configured by the terminal device). For example, the terminal device may determine whether to monitor the PDCCH in the first CORESET within the valid time based on the association between the TCI state (or the TCI state in the activated state) configured for the first CORESET and the target beam.

[0130] The following, with reference to specific examples, describes in more detail how a terminal device determines whether to monitor the PDCCH in the first CORESET during the activation time. It should be noted that the following examples are intended solely to help those skilled in the art understand the embodiments of the present application and are not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. Based on the following examples, it will be apparent that those skilled in the art can make various equivalent modifications or variations, and such modifications or variations also fall within the scope of the embodiments of the present application. It should also be understood that the reference to "the TCI state configured in the CORESET is associated with the target beam" in the following examples means that the QCL information included in the TCI state configured in the CORESET is associated with the target beam, or in other words, the beam associated with the QCL information is the same as the target beam. Similarly, the reference to "the TCI state configured in the CORESET is not associated with the target beam" in any embodiment of the present application means that the QCL information included in the TCI state configured in the CORESET is not associated with the target beam, or in other words, the beam associated with the QCL information is different from the target beam.

[0131] Example 1:

[0132] If all TCI states configured by the first CORESET are associated with the target beam, the terminal device monitors the PDCCH in the first CORESET within the valid time; and / or, if at least one TCI state configured by the first CORESET is not associated with the target beam, the terminal device does not monitor the PDCCH in the first CORESET within the valid time.

[0133] For example, the terminal device is configured with a first CORESET, and the first CORESET is configured with a TCI state. The TCI state includes QCL information, and the QCL information includes SSB index 0. The terminal device receives a first downlink signaling (which can be the first DCI or the first MAC CE mentioned above), and the first downlink signaling indicates that the beam corresponding to SSB index 0 is in an activated state within the valid time. In this case, the terminal device will monitor the PDCCH in the first CORESET within the valid time. However, if the first downlink signaling indicates that the beam corresponding to SSB index 0 is in an inactive state within the valid time, the terminal device does not monitor the PDCCH in the first CORESET within the valid time.

[0134] Example 2:

[0135] If at least one TCI state configured by the first CORESET is associated with the target beam, the terminal device monitors the PDCCH in the first CORESET within the valid time; and / or, if none of the TCI states configured by the first CORESET are associated with the target beam, the terminal device does not monitor the PDCCH in the first CORESET within the valid time.

[0136] For example, the terminal device is configured with a first CORESET, and the first CORESET is configured with two TCI states. Both TCI states include QCL information, namely QCL information 1 and QCL information 2. QCL information 1 contains SSB index 0, and QCL information 1 contains SSB index 1. The terminal device receives the first downlink signaling (which can be the first DCI or the first MAC CE mentioned above), and the first downlink signaling indicates that the beam corresponding to SSB index 0 is in an activated state, then the terminal device monitors the PDCCH in the first CORESET within the valid time. However, if QCL information 1 and QCL information 2 contain SSB index 1 and SSB index 2, respectively, the terminal device does not monitor the PDCCH in the first CORESET within the valid time. This is because the beam corresponding to SSB index 1 and the beam corresponding to SSB index 2 are not in an activated state.

[0137] Example 3:

[0138] If the first TCI state configured by the first CORESET is associated with the target beam, the terminal device monitors the PDCCH in the first CORESET within the valid time; and / or, if the first TCI state configured by the first CORESET is not associated with the target beam, the terminal device does not monitor the PDCCH in the first CORESET within the valid time; wherein the first TCI state is an activated TCI state among the TCI states configured by the first CORESET (the activated TCI state in the first CORESET can be determined, for example, according to the configuration information of the network device).

[0139] For example, the first CORESET is configured with TCI state 1 and TCI state 2. TCI state 1 is associated with SSB index 0 (such as the QCL information in TCI state 1 contains SSB index 0), and TCI state 2 is associated with SSB index 1 (such as the QCL information in TCI state 2 contains SSB index 1). The network device indicates that TCI state 1 is in an activated state through configuration information. In this case, if the first downlink signaling received by the terminal device indicates that the beam corresponding to SSB index 0 is in an activated state, the terminal device monitors the PDCCH in the first CORESET within the valid time; if the first downlink signaling received by the terminal device indicates that the beam corresponding to SSB index 0 is in an inactivated state, the terminal device does not monitor the PDCCH in the first CORESET within the valid time.

[0140] In some implementations, the terminal device may determine the active TCI in the TCI state configured by the first CORESET based on the target beam. For example, if the first CORESET is configured with a first TCI state and a second TCI state, and the first TCI state is active, if the first TCI state is not associated with the target beam and the second TCI state is associated with the target beam, the terminal device may determine the second TCI state as the active TCI state. Furthermore, in some implementations, the terminal device may monitor the PDCCH in the first CORESET within the valid time.

[0141] Exemplarily, the first CORESET is configured with TCI state 1 and TCI state 2. TCI state 1 is associated with SSB index 0 (such as the QCL information in TCI state 1 contains SSB index 0), and TCI state 2 is associated with SSB index 1 (such as the QCL information in TCI state 2 contains SSB index 1). The network device indicates that TCI state 1 is in an activated state through configuration information. Furthermore, the terminal device receives a first downlink signaling, and the first downlink signaling indicates that the beam corresponding to SSB index 1 is in an activated state, and the beam corresponding to SSB index 0 is in an inactivated state. In this case, the terminal device can assume that the activated TCI state of the first CORESET changes from TCI state 1 to TCI state 2. Then, the terminal device can monitor the PDCCH in the first CORESET within the valid time.

[0142] Furthermore, in some implementations, if the TCI states configured in the first CORESET include multiple TCI states associated with the target beam (assuming that the first TCI state is an active TCI state and is not associated with the target beam), the second TCI state mentioned above can be determined from the multiple TCI states. For example, the second TCI state can be one of the following: the TCI state with the smallest index among the multiple TCI states; or the TCI state with the largest index among the multiple TCI states.

[0143] For example, the first CORESET is configured with TCI state 1, TCI state 2 and TCI state 3, wherein TCI state 1 is associated with SSB index 0 (such as the QCL information in TCI state 1 contains SSB index 0), TCI state 2 is associated with SSB index 1 (such as the QCL information in TCI state 2 contains SSB index 1), and TCI state 3 is associated with SSB index 2 (such as the QCL information in TCI state 3 contains SSB index 2). The network device indicates that TCI state 1 is in an activated state through configuration information. Furthermore, the terminal device receives a first downlink signaling, and the first downlink signaling indicates that the beams corresponding to SSB index 1 and SSB index 2 are in an activated state, and the beam corresponding to SSB index 0 is in an inactivated state. In this case, the terminal device can change the TCI state with the smallest index, that is, the TCI state corresponding to TCI index 2, to an activated state; or, the terminal device can also change the TCI state with the largest index, that is, the TCI state corresponding to TCI index 3, to an activated state.

[0144] In some implementations, if the TCI state configured for CORESET0 is not associated with the target beam, the terminal device does not monitor the PDCCH in CORESET0 during the valid time. This implementation does not limit the method for determining the TCI state of CORESET0. For example, the TCI state of CORESET0 can be quasi-co-located with the SSB index determined in the initial access procedure (such as the random access channel (RACH) procedure).

[0145] In some implementations, if the TCI state configured for CORESET0 is not associated with the target beam, the terminal device determines the TCI state corresponding to CORESET0 based on the target beam. For example, if the target beam includes one beam, the terminal device may determine that CORESET0 corresponds to a third TCI state, where the third TCI state is associated with the target beam. For another example, if the target beam includes multiple beams, the terminal device may determine that CORESET0 corresponds to a fourth TCI state, where the fourth TCI state is associated with at least one beam among the multiple beams.

[0146] In some implementations, the terminal device does not expect to receive first indication information within the valid time. The first indication information is used to configure the TCI state corresponding to the first CORESET configured by the terminal device to a TCI state not associated with the target beam.

[0147] Regarding signals other than PDCCH

[0148] In some implementations, a terminal device may receive a first physical downlink shared channel (PDSCH) during the valid time. The first PDSCH may be scheduled based on a second DCI, and the second DCI may indicate a fourth TCI state that may be used for reception of the first PDSCH. In this case, the terminal device does not expect the fourth TCI state to be unassociated with the target beam.

[0149] In some implementations, the fourth TCI state may be a TCI state in a candidate TCI state set. The candidate TCI state set may be configured based on an RRC or MAC CE. The terminal device may consider a TCI state in the candidate TCI state set that is not associated with the target beam to be an invalid TCI state within the valid time.

[0150] In some implementations, if the terminal device is configured to receive a first signal and the TCI state corresponding to the first signal is not associated with the target beam, the terminal device does not receive the first signal within the valid time; wherein the first signal may include one or more of PDSCH, semi-persistent scheduling (SPS)-PDSCH and CSI-RS.

[0151] In some implementations, if the first paging occasion configured by the terminal device falls within the valid time, and if the TCI state corresponding to the first paging occasion is not associated with the target beam, the terminal device does not monitor the paging message during the first paging occasion. Otherwise, the terminal device may monitor the paging message during the first paging occasion.

[0152] The wireless communication method provided in the embodiments of the present application is described in detail above from the perspective of a terminal device. The wireless communication method provided in the embodiments of the present application is described in detail below from the perspective of a network device. It should be understood that the description on the network device side corresponds to the description on the terminal device side, and for the sake of brevity, repeated descriptions are omitted as appropriate.

[0167] In some implementations, the time slots corresponding to the multiple listening opportunities are continuous time slots; or, the symbols corresponding to the multiple listening opportunities are continuous symbols.
