These terms are used only to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word “if,” as used herein, can be interpreted as “when,” “in response to a determination,” or “when…”.

[0046] First, the relevant technologies involved in the embodiments of this application will be introduced:

[0047] • Quasi-co-location configuration and Transmission Configuration Indicator (TCI) state in New Radio (NR):

[0048] In NR Release 17, the unified TCI framework defines a joint TCI mode, where the TCI state in a joint TCI mode can simultaneously indicate both uplink and downlink beams. The unified TCI framework also defines a separate TCI mode, where the TCI state includes an uplink TCI state and a downlink TCI state. The uplink TCI state indicates the uplink beam, and the downlink TCI state indicates the downlink beam.

[0049] The unified TCI framework adopts a manner of Radio Resource Control (RRC), Medium Access Control (MAC) Control Element (CE) combined with Downlink Control Information (DCI) to indicate the TCI state in a joint TCI mode or the uplink TCI state and the downlink TCI state in a separate TCI mode. The specific indication manner is as follows:

[0050] First, a set of TCI states is configured using RRC signaling. If it is a joint TCI mode, a set of joint TCI states is configured using RRC signaling; if it is a separate TCI mode, a set of uplink TCI states and a set of downlink TCI states are configured using RRC signaling.

[0051] Second, one or more TCI states are activated from the set of TCI states configured by RRC signaling using MAC CE signaling. In the joint TCI mode, K TCI states are activated by the MAC CE signaling, and K is less than or equal to 8; in the separate TCI mode, K pairs of {downlink TCI state, uplink TCI state} are activated by the MAC CE signaling, and K is less than or equal to 8.

[0052] Finally, the DCI signaling indicates the TCI state or pair of TCI states used for the current transmission from the K TCI states in the joint TCI mode or the K pairs of {downlink TCI state, uplink TCI state} in the separate TCI mode.

[0053] Among them, a TCI state can contain the following configurations: TCI state identification, used to identify a TCI state; Quasi Co-Location (QCL) information 1; QCL information 2.

[0054] Among them, a QCL information contains the following information: QCL type configuration; QCL reference signal configuration.

[0055] Among them, the QCL type configuration can be any one of QCL type A, QCL type B, QCL type C, and QCL type D (in the subsequent description, in order to simplify, some places will omit QCL, such as directly writing type A).

[0056] In some embodiments, the definitions of different QCL type configurations are as follows:

[0057] 'QCL Type A': {Doppler shift, Doppler spread, average delay, delay spread};

[0058] 'QCL Type B': {Doppler shift, Doppler spread};

[0059] 'QCL Type C': {Doppler shift, average delay};

[0060] 'QCL Type D': {Spatial Rx parameter}.

[0061] In some embodiments, the QCL reference signal configuration includes a cell identity where the reference signal is located, a Band Width Part (BWP) identity, and reference signal information. Optionally, the reference signal information can be a Channel State Information Reference Signal (CSI-RS) resource identity or a Synchronization Signal Block (SSB) index.

[0062] • Introduction of Near-Field Communication:

[0063] For future 6th-Generation (6G) networks, larger antenna apertures and higher frequency bands (e.g., centimeter wave, millimeter wave, and terahertz) will be adopted, which makes the near-field characteristics more significant. In addition, the introduction of emerging technologies such as Reconfigurable Intelligent Surface (RIS), Massive Multiple-Input Multiple-Output (MIMO), movable antennas, and cell-free networks also makes the near-field scenario more common in future wireless networks. In the near-field scenario, due to the change of electromagnetic wave propagation characteristics, it is no longer possible to simply approximate as a plane wave, but it needs to be considered as a spherical wave. From the perspective of spatial resource utilization, although the traditional wireless communication system has made significant achievements in the excavation and utilization of far-field spatial resources, further exploration and application of near-field spatial resources are expected to bring new physical spatial dimensions to wireless communication systems.

[0064] For the division of near-field and far-field regions, the following method is generally used in the academic field:

[0065] Assuming that the antenna aperture is D and the wavelength is λ, then is the far field, and the wave front is approximately a plane wave; is the radiation near field, and the wave front is a spherical wave. r represents the distance between the terminal device and the network device.

[0066] FIG. 1 shows a schematic diagram of a communication system provided by an example embodiment of the present application. The communication system includes a network device 110 and a terminal device 120, and / or the terminal device 120 and a terminal device 130, which are not limited by the present application.

[0068] The terminal device 120 and / or the terminal device 130 in the present application, also known as a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, a user device. The terminal includes but is not limited to: a handheld device, a wearable device, a vehicle-mounted device, and an Internet of Things device, etc., such as: a mobile phone, a tablet computer, an electronic book reader, a laptop computer, a desktop computer, a television, a game console, a mobile Internet device (MID), an augmented reality (AR) terminal, a virtual reality (VR) terminal, and a mixed reality (MR) terminal, a wearable device, a handle, an electronic tag, a controller, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wireless terminal in remote medical surgery, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a television set top box (STB), a customer premise equipment (CPE), etc.

[0069] The network device 110 and the terminal device 120 communicate with each other through a certain air interface technology, such as the Uu interface. For example, there are two communication scenarios between the network device 110 and the terminal device 120: uplink communication scenario and downlink communication scenario. Among them, the uplink communication refers to sending signals to the network device 110; the downlink communication refers to sending signals to the terminal device 120.

[0070] The terminal device 120 and the terminal device 130 communicate with each other through a certain air interface technology, for example, a Uu interface. Exemplarily, there are two communication scenarios between the terminal device 120 and the terminal device 130: a first sidelink communication scenario and a second sidelink communication scenario. Among them, the first sidelink communication refers to sending a signal to the terminal device 130; the second sidelink communication refers to sending a signal to the terminal device 120.

[0071] The terminal device 120 and the terminal device 130 are both in network coverage and located in the same cell, or the terminal device 120 and the terminal device 130 are both in network coverage but located in different cells, or the terminal device 120 is in network coverage but the terminal device 130 is out of network coverage.

[0072] The technical solutions provided by the embodiments in the present application can be applied to various communication systems, for example: a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an Advanced Long Term Evolution (LTE-A) system, a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a 5th Generation (5G) mobile communication system, a New Radio (NR) system, an evolved system of the NR system, an LTE-based access to unlicensed spectrum (LTE-U) system, an NR-based access to unlicensed spectrum (NR-U) system, a Terrestrial Networks (TN) system, a Non-Terrestrial Networks (NTN) system, a Wireless Local Area Networks (WLAN), a Wireless Fidelity (Wi-Fi), a cellular Internet of Things system, a cellular passive Internet of Things system, and can also be applicable to an evolved system of the 5G NR system, and can also be applicable to a Beyond Fifth Generation (B5G) system, a Sixth Generation (6G) system, and an evolved system of the 6G system. In some embodiments of the present application, the "NR" can also be referred to as a 5G NR system or a 5G system.The 5G mobile communication system can include non-standalone (NSA) and / or standalone (SA).

[0073] The technical solutions provided by the embodiments in this application can also be applied to machine type communication (MTC), long term evolution-machine (LTE-M), device to device (D2D) network, machine to machine (M2M) network, Internet of Things (IoT) network or other networks. The IoT network may, for example, include a vehicle network. In the vehicle network system, the communication modes are collectively referred to as vehicle to X (V2X, X can represent any object), for example, the V2X can include vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian (V2P) communication or vehicle to network (V2N) communication, etc.

[0074] The communication system provided by the embodiments can be applied to one or more of the following communication scenarios: uplink communication scenario, downlink communication scenario, sidelink communication scenario.

[0075] In the related art, the introduction of a large-scale antenna array not only improves the system capacity and coverage range of the communication system, but also significantly shortens the near-field communication area. It should be understood that the near-field communication area described in the embodiments of the present application is a concept corresponding to the far-field communication area. The near-field communication area refers to a communication coverage range close to the network device, and the near-field communication area can also be referred to as a near-field area or a near-field communication range or a near-field range. The far-field communication area refers to a communication coverage range far from the network device, and the far-field communication area can also be referred to as a far-field area or a far-field communication range or a far-field range.

[0076] In some embodiments, in the near-field communication area, due to the change of electromagnetic wave propagation characteristics, the near-field beam can no longer be simply approximated as the same plane wave as the far-field beam, but needs to be regarded as a spherical wave. For example, as shown in FIG. 2, the near-field beam in the near-field communication area is a spherical wave beam, the far-field beam in the far-field communication area is a plane wave beam, and the near-field beam is different from the far-field beam.

[0077] In the related art, a terminal device usually uses a far-field beam as a receiving beam. However, when the terminal device is in a near-field communication area, using the far-field beam as the receiving beam cannot accurately adapt to the requirements of near-field communication transmission. Based on this, an information indication method is proposed in the embodiments of the present application, which can accurately indicate the transmission configuration related to near-field communication.

[0078] FIG. 3 shows a flowchart of an information indication method provided by an example embodiment of the present application. The method is performed by a terminal device, and the method includes:

[0079] Step 220: The terminal device determines transmission indication information.

[0080] The transmission indication information is associated with a first QCL configuration. The transmission indication information and / or the first QCL configuration is associated with near-field communication, or the transmission indication information carries information related to a position and / or a distance.

[0081] In some embodiments, the transmission indication information and / or the first QCL configuration is associated with first distance range communication. Optionally, the first distance range further includes one or more sub-distance ranges. That is, the first distance range is a set of one or more sub-distance ranges, or the one or more sub-distance ranges constitute the first distance range. For example, the first distance range includes {sub-distance range 1, sub-distance range 2, sub-distance range 3}. Wherein, the first distance between the sub-distance range 1 and the network device is less than the second distance between the sub-distance range 2 and the network device, and the second distance between the sub-distance range 2 and the network device is less than the third distance between the sub-distance range 3 and the network device. In the embodiments of the present application, the first distance range can also be understood as a near-field communication range or a near-field range, and the first distance range communication can also be understood as near-field communication.

[0082] By determining the transmission indication information associated with near-field communication, it is beneficial to enable the terminal device to select a suitable near-field beam as a receiving beam in the near-field communication area, thereby facilitating accurate adaptation to the requirements of near-field communication transmission.

[0083] In some embodiments, the transmission indication information is used to indicate a first TCI state set. The first TCI state set includes one or more first TCI states. The first TCI state set includes a TCI state set applied to a near-field or near-field communication or near-field beam, or the first TCI state set includes a TCI state set applied to a first distance range. The first TCI state corresponds to a near-field beam.

[0084] In some embodiments, in the case that the first distance range includes one or more sub distance ranges, the first TCI state set includes a TCI state set applied to each sub distance range. For example, assuming that the first distance range includes {sub distance range 1, sub distance range 2, sub distance range 3}, the first TCI state set includes a first TCI state set 1 applied to sub distance range 1, a first TCI state set 2 applied to sub distance range 2, and a first TCI state set 3 applied to sub distance range 3.

[0085] In some embodiments, the transmission indication information carries information related to the location of the terminal device, or information related to the location of the network device, or information related to the target location.

[0086] In some embodiments, the transmission indication information carries information related to the distance between the terminal device and the network device, or information related to the target distance.

[0087] By carrying information related to the location and / or distance, it is beneficial to determine whether the current terminal device is in the near field communication area or in the far field communication area, thereby facilitating the terminal device to select a suitable beam as a receiving beam in different communication areas. For example, when the terminal device is in the near field communication area, a near field beam is selected as the receiving beam; when the terminal device is in the far field communication area, a far field beam is selected as the receiving beam.

[0088] FIG. 4 shows a flowchart of an information indication method according to an example embodiment of the present application. The method is performed by a network device, and the method includes:

[0089] Step 320: The network device determines the transmission indication information.

[0090] The transmission indication information is associated with the first QCL configuration. The transmission indication information and / or the first QCL configuration is associated with near field communication, or the transmission indication information carries information related to the location and / or distance.

[0091] In some embodiments, the transmission indication information and / or the first QCL configuration is associated with the first distance range communication. Optionally, the first distance range further includes one or more sub distance ranges. That is, the first distance range is a set of the one or more sub distance ranges, or the one or more sub distance ranges constitute the first distance range. For example, the first distance range includes {sub distance range 1, sub distance range 2, sub distance range 3}. Wherein the first distance between the sub distance range 1 and the network device is less than the second distance between the sub distance range 2 and the network device, and the second distance between the sub distance range 2 and the network device is less than the third distance between the sub distance range 3 and the network device. In the embodiments of the present application, the first distance range can also be understood as a near field communication range or a near field range, and the first distance range communication can also be understood as near field communication.

[0092] By determining the transmission indication information associated with the near field communication, it is beneficial to enable the terminal device to select a suitable near field beam as a receiving beam in the near field communication area, thereby facilitating accurate adaptation to the needs of near field communication transmission.

[0093] In some embodiments, the transmission indication information is used to indicate a first TCI state set. The first TCI state set includes one or more first TCI states. The first TCI state set includes a set of TCI states applied to the near field or near field communication or near field beam, or the first TCI state set includes a set of TCI states applied to the first distance range. The first TCI state corresponds to the near field beam.

[0094] In some embodiments, in the case where the first distance range includes one or more sub distance ranges, the first TCI state set includes a set of TCI states applied to each sub distance range. For example, assuming that the first distance range includes {sub distance range 1, sub distance range 2, sub distance range 3}, the first TCI state set includes a first TCI state set 1 applied to the sub distance range 1, a first TCI state set 2 applied to the sub distance range 2, and a first TCI state set 3 applied to the sub distance range 3.

[0095] In some embodiments, the transmission indication information carries information related to the location of the terminal device, or information related to the location of the network device, or information related to the target location.

[0096] In some embodiments, the transmission indication information carries information related to the distance between the terminal device and the network device, or information related to the target distance.

[0097] By carrying the information related to the position and / or distance, it is beneficial to determine whether the terminal device is in the near field communication area or in the far field communication area, so as to facilitate the terminal device to select a suitable beam as the receiving beam in different communication areas. For example, when the terminal device is in the near field communication area, the near field beam is selected as the receiving beam; when the terminal device is in the far field communication area, the far field beam is selected as the receiving beam.

[0098] On the basis of the embodiment shown in FIG. 3 or the embodiment shown in FIG. 4, the first QCL configuration is introduced as follows:

[0099] In some embodiments, the first QCL configuration is used to indicate the first position value and / or the first distance value of the near field beam; or, the first QCL configuration is used to indicate the first position value and / or the first distance value; or, the first QCL configuration is associated with the first position value and / or the first distance value.

[0100] In some embodiments, the first position value is an absolute position value. For example, the first position value is used to indicate the determined position of the near field beam, including the positioning information and / or the directional information of the near field beam.

[0101] In some embodiments, the first position value is a relative position value. For example, the first position value is used to indicate the relative position of the near field beam relative to the network device, including the distance and / or the angle of the near field beam relative to the network device.

[0102] In some embodiments, in the case that the first position value is an absolute position value or a relative position value, the first position value can also be understood as the position value corresponding to the position farthest from the network device in the near field communication area. Or, it can be understood as the position value corresponding to the position farthest from the network device in the first distance range.

[0103] In some embodiments, in the case that the target position value is greater than the first position value, the terminal device uses the far field beam as the receiving beam; in the case that the target position value is less than or equal to the first position value, the terminal device uses the near field beam as the receiving beam. Wherein, the target position value is the position value of the terminal device.

[0104] Optionally, the target position value greater than the first position value can also be understood as: the terminal device is not in the near field communication area, or the terminal device is in the far field communication area.

[0105] Optionally, the target position value less than or equal to the first position value can also be understood as: the terminal device is in the near field communication area, or the terminal device is not in the far field area.

[0106] In some embodiments, the first position value is a position range value. Optionally, the first position value is used to indicate the position range of the near field beam, such as the first distance range.

[0107] In some embodiments, the first distance value is an absolute distance value. For example, the first distance value is directly used to indicate an absolute distance between the near-field beam and the transmit antenna panel of the network device. For example, the first distance value is X, and X is directly used to represent the distance between the near-field beam and the transmit antenna panel of the network device.

[0108] In some embodiments, the first distance value is a phase distance value. For example, the first distance value is used to indicate the distance of the near-field beam relative to the transmit antenna panel of the network device. For example, the first distance value is Y, and Y represents the distance of the near-field beam relative to the transmit antenna panel of the network device with the transmit antenna panel of the network device as a fixed reference point.

[0109] In some embodiments, when the first distance value is an absolute distance value or a relative distance value, the first distance value can also be understood as a maximum distance value between the near-field beam and the network device within the near-field communication region. Or, it can be understood as a maximum distance value between the beam and the network device within the first distance range.

[0110] In some embodiments, when the target distance value is greater than the first distance value, the terminal device uses a far-field beam as a receiving beam; when the target distance value is less than or equal to the first distance value, the terminal device uses a near-field beam as a receiving beam. Wherein, the target distance value is a distance value between the terminal device and the network device.

[0261] The third transmission indication information is used to indicate a first TCI state set, and the first TCI state set includes a TCI state set applied to a first distance range.

[0262] In some embodiments, the first TCI state set includes a first joint TCI state set in a joint mode, and the first joint TCI state set is applied to uplink communication and downlink communication; or, the first TCI state set includes a first uplink TCI state set and a first downlink TCI state set in a separate mode, the first uplink TCI state set is applied to uplink communication, and the first downlink TCI state set is applied to downlink communication.

Or, the third indication information is used to indicate that the terminal device is within the near field communication area or is not within the near field communication area. Or, the third indication information is used to indicate that the distance between the terminal device and the network device is less than or equal to the first distance threshold, or the distance between the terminal device and the network device is greater than the first distance threshold.

Or, when the third indication information is 1, the third information indicates that the terminal device is in the first distance range; when the third indication information is 0, the third information indicates that the terminal device is not in the first distance range.

[0297] In some embodiments, the target bit in the third indication information corresponds to the TCI state set applied to the target distance range.

[0298] For example, when the value of the i-th bit in the third indication information is 0, the third information indicates that the terminal device is in the i-th distance range, and i is a positive integer. Or, when the value of the i-th bit in the third indication information is 1, the third information indicates the TCI state set applied to the i-th distance range, and i is a positive integer.

When the third indication information is 00, the third information is used to indicate that the terminal device is in the first distance range. When the third indication information is 01, the third information is used to indicate that the terminal device is in the second distance range. When the third indication information is 10, the third information is used to indicate that the terminal device is in the third distance range. When the third indication information is 11, the third information is used to indicate that the terminal device is in the fourth distance range.
