Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for determining time-domain location. Background Technology

[0002] Currently, with the evolution of new radio (NR) technology, the available frequency bands are constantly increasing. The FR1 (Frequency Range 1) band mainly refers to the 450MHz to 6GHz bandwidth, and the FR2 (Frequency Range 2) band mainly refers to the 24.25GHz to 52.6GHz bandwidth. For example, the FR1 band can support sub-carrier spacing (SCS) of 15KHz and 30KHz, while the FR2 band can support SCS of 60KHz, 120KHz, and 240KHz or larger.

[0003] In existing technologies, during the initial access process, the terminal device first demodulates the synchronization signal / physical broadcast channel (SSB) to obtain the type 0 physical downlink control channel (type 0-PDCCH) and the physical downlink shared channel (PDSCH). The type 0-PDCCH contains a control resource set, such as control resource set 0 (CORESET#0). The time-domain location of CORESET#0 can then be found based on the relative relationship between CORESET#0 and the SSB. Furthermore, the scheduling information of SIB1 is obtained from CORESET#0 to achieve initial access.

[0004] CORESET#0 requires parameter configuration, and the terminal device UE can further obtain the time domain information of CORESET#0 through the configured parameters.

[0005] Due to the increase in high-frequency subcarrier spacing, the current CORESET#0 configuration parameters are no longer applicable. Therefore, designing corresponding parameters for the time-frequency resource information of the control resource set for high-frequency subcarrier spacing has become an urgent problem to be solved in the industry. Summary of the Invention

[0006] This application provides a method and apparatus for determining the time-domain location, which can provide parameters of the corresponding control resource set for the SSB of the high-frequency subcarrier spacing, thereby accurately determining the time-domain location of the control resource set corresponding to the SSB.

[0007] In a first aspect, a method for determining time-domain location is provided. This method can be executed by a terminal device, or by a chip or circuit configured in the terminal device, and this application does not limit the execution of such method.

[0008] The method includes: determining the index of a first SSB, wherein the subcarrier spacing of the first SSB is greater than or equal to 120 kHz; determining the starting time domain position of a first control resource set based on at least one of a first indication information, a first duration or a first window, first information, a first relationship, and a first delay, and the index of the first SSB, wherein the first indication information indicates the time domain position of the first control resource set in the first half-frame or the second half-frame within a first system frame, the first duration includes the duration occupied by the first SSB for complete transmission within the first system frame, the first window is a preset duration occupied by transmitting the first SSB, the first information is the number of time slots available for transmitting uplink data and the position of the time slots, the first relationship is the ratio of the subcarrier spacing of the first SSB to 120 kHz, and the first delay is the access delay of the terminal device UE.

[0009] According to the scheme of this application, the starting time domain position of the first control resource set is determined based on at least one of the first indication information, the first duration or the first window, the first information, the first relationship, and the first delay, and the index of the first SSB. This enables the starting position of the first control resource set to be adapted to the subcarrier spacing of the high-frequency band, thereby making the starting time domain position of the first SSB CORESET#0 more accurate and improving the detection performance.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the subcarrier spacing of the first SSB is equal to 120 kHz, 480 kHz, or 960 kHz.

[0011] According to this technical solution, the subcarrier spacing of the first SSB is equal to 120kHz, 480kHz or 960kHz. Increasing the subcarrier spacing of the first SSB shortens the absolute time corresponding to each time slot, reduces the latency, and helps to reduce the initial access latency of the terminal device.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the method specifically includes: determining the starting time domain position of the first control resource set based on the first indication information, the first duration or the first window, the first information, the first delay, and the index of the first SSB; or

[0013] Based on the first indication information, the first duration or first window, the first relationship, and the index of the first SSB, determine the starting time domain position of the first control resource set; or

[0014] Based on the first indication information and the index of the first SSB, determine the starting time-domain position of the first control resource set, or

[0015] Based on the first duration or the first window and the index of the first SSB, determine the starting time domain position of the first control resource set, or

[0016] Based on the first information and the index of the first SSB, the starting time-domain position of the first control resource set is determined.

[0017] In the above implementation, the starting time-domain position of the first control resource set is determined based on at least one of the first indication information, the first duration or the first window, the first information, the first relationship, and the first delay, and the index of the first SSB. This enables the starting position of the first control resource set to be adapted to the subcarrier spacing of the high-frequency band, thereby making the starting time-domain position of the first SSB's CORESET#0 more accurate and improving the detection performance.

Wherein,

[0019] In one possible implementation, the initial temporal position n0 of the first control resource set satisfies the following condition:

[0020]

[0021] This indicates the number of time slots within the first system frame.

[0022] i represents the index of the first SSB.

[0023] O represents the offset of the first control resource set relative to the start position of even-numbered frames when the index value of the first SSB is 0. O is determined according to the first indication information, the first duration or the first window, the first information, and the first delay.

[0024] O*2 μ This indicates the number of time slots contained within O ms.

[0025] M represents the time slot of the first control resource set corresponding to two adjacent SSBs in the first SSB. M is determined according to the first indication information, the first duration or the first window, the first information, and the first delay.

[0026] In the above implementation, the values ​​of parameters O and M are determined based on the first indication information, the first duration or the first window, the first information, and the first delay. These O and M values ​​can then be used to further determine the time-domain position of the first SSB's CORESET#0. This scheme adaptively adjusts the O and M values, meeting the requirements for high-frequency subcarrier spacing, and is more flexible with lower design complexity.

[0027] In another possible implementation, the starting temporal position n0 of the first control resource set satisfies the following condition:

[0033] O*2 μ This indicates the number of time slots contained within an Oms.

[0034] M represents the time slot interval of the first control resource set corresponding to two adjacent SSBs in the first SSB, and M is determined according to the first duration or first window, first information and first delay.

[0035] For example, half-frame bits n hf The value can be 0 or 1. When n hf A value of 0 indicates that the first control resource set is located in the first half-frame, when n hf When the value is 1, it indicates that the first control resource set is located in the second half of the frame.

[0036] In the above implementation, the values ​​of parameters O and M are determined based on the first duration or first window, first information, and first delay. Furthermore, the time-domain position of the first SSB's CORESET#0 can be determined based on the first indication information and these O and M values. This scheme adaptively adjusts the O and M values ​​and the formula for calculating the first control resource set, meeting the requirements for high-frequency subcarrier spacing, and is more flexible with lower design complexity.

[0037] In conjunction with the first aspect, in certain implementations of the first aspect, the starting temporal location of the first control resource set is determined based on the first instruction information, the first duration or first window, the first relationship, and the index of the first SSB. Wherein,

[0038] In one possible implementation, the initial temporal position n0 of the first control resource set satisfies the following condition:

[0046] In the above implementation, the parameter O is scaled based on 120kHz according to the first relationship, and the parameter O value is further determined according to the first indication information, the first duration or the first window, and the first information. This can meet the requirements of high-frequency subcarrier spacing, and the configuration parameters of the first control resource set can include only two different O values, saving overhead and reducing design complexity.

[0047] In another possible implementation, the starting temporal position n0 of the first control resource set satisfies the following condition:

[0048]

[0049] This indicates the number of time slots within the first system frame.

[0057] In the above implementation, the O value of the first SSB is scaled based on 120kHz according to the first relationship. The parameter O value is further determined according to the first duration or the first window. The formula for calculating the time domain position of the first control resource set is adjusted in combination with the first indication information. The time domain position of CORESET#0 of the first SSB can be further determined by the O value, the M value and the adjusted formula. This scheme adaptively adjusts the O value and the formula, which can meet the requirements of high frequency subcarrier spacing. Moreover, the configuration parameters of the first control resource set (e.g., the MO table) can ultimately include only two different O values, saving table overhead and reducing design complexity.

[0058] In conjunction with the first aspect, in some implementations of the first aspect, the two different O values ​​are 0 and 5ms.

[0059] In conjunction with the first aspect, in some implementations of the first aspect, the starting temporal location of the first control resource set is determined based on the first indication information and the index of the first SSB, or

[0060] Based on the first duration or the first window and the index of the first SSB, determine the starting time domain position of the first control resource set, or

[0061] Based on the first information and the index of the first SSB, the starting time-domain position of the first control resource set is determined. In one possible implementation, the starting time-domain position n0 of the first control resource set satisfies the following condition:

[0062]

[0063] This indicates the number of time slots within the first system frame.

[0064] i represents the index of the first SSB.

[0065] O represents the offset of the first control resource set relative to the start position of even-numbered frames when the index value of the first SSB is 0. O is determined based on one of the first indication information, the first duration or the first window, or the first information.

[0066] O*2 μ This indicates the number of time slots contained within an Oms.

[0067] M represents the time slot interval of the first control resource set corresponding to two adjacent SSBs in the first SSB. M is determined according to the first indication information, the first duration, or the first window and the first information.

[0068] In the above implementation, the parameter O value and M value are determined according to the first indication information, the first duration, the first window, or the first information. The time domain position of the first SSB CORESET#0 can be further determined by the O value and M value. This scheme can adaptively adjust the O value and M value to meet the specific requirements of the high-frequency subcarrier spacing. It is highly targeted, more flexible, and has low design complexity.

[0069] In conjunction with the first aspect, in some implementations of the first aspect, the starting temporal location of the first control resource set is determined based on the first indication information and the index of the first SSB. Wherein,

[0070] In one possible implementation, the first indication information is half-frame bits n hf The initial time-domain position n0 of the first control resource set satisfies the following condition:

[0071] or

[0072]

[0073] The O1 value is based on the n hf Determined, the value is:

[0074] in, This indicates the number of time slots within the first system frame. Represents the absolute time of half a system frame.

[0075] O1*2 μ This indicates the number of time slots contained within O1ms.

[0076] half-frame bits n hf The temporal location of the first control resource set is either in the first half-frame or the second half-frame within the first system frame.

[0077] i represents the index of the first SSB.

[0078] O represents the offset of the first control resource set relative to the start position of even-numbered frames when the index value of the first SSB is 0.

[0079] M represents the time slot of the first control resource set corresponding to two adjacent SSBs in the first SSB.

[0080] Optional, It can be 5ms.

[0081] Optionally, the values ​​of O and M can be preset values.

[0082] In the above implementation, the terminal device can determine whether the time domain position of the first SSB transmission is in the first half frame or the second half frame based on the half frame bits. The parameters O and M values ​​or the formula can be adjusted based on the half frame bits. The time domain position of the first SSB's CORESET#0 can be further determined by the O and M values ​​or the formula. This distinguishes whether the starting time domain position of the CORESET#0 corresponding to the same SSB index is in the first half frame or the second half frame. This avoids the situation where the SSB of the second half frame is associated with the time slot of the first half frame, causing the SSB of the second half frame and its corresponding Type 0-PDCCH-CSS to be undetectable. It can also improve the detection speed of SSB and its corresponding Type 0-PDCCH-CSS and save UE access time.

[0083] In another possible implementation, the first indication information is the slot index of the first SSB. id The initial time-domain position n0 of the first control resource set satisfies the following condition:

[0084] or

[0085]

[0086] The O2 value is based on the slot id It is determined that the value can be:

[0087] in, This indicates the number of time slots within the first system frame. Represents the absolute time of half a system frame.

[0088] k according to the slot id Determined, used to indicate whether the temporal location of the first control resource set is in the first half-frame or the second half-frame.

[0090] i represents the index of the first SSB.

[0091] O represents the offset of the first control resource set relative to the start position of even-numbered frames when the index value of the first SSB is 0.

[0092] O*2 μ This indicates the number of time slots contained within an Oms.

[0094] Optional, It can be 5ms.

[0095] Optionally, the value of k can be...

[0096] Optionally, the values ​​of O and M can be preset values.

[0097] In the above implementation, the terminal device can determine whether the time domain position of the first SSB transmission is in the first half frame or the second half frame based on the time slot index. The parameters O and M are adjusted or the formula is adjusted according to the time slot index. The time domain position of the first SSB's CORESET#0 can be further determined by the O and M values ​​or the formula. This distinguishes whether the starting time domain position of CORESET#0 corresponding to the same SSB index is in the first half frame or the second half frame. This avoids the situation where the SSB in the second half frame is associated with the time slot of the first half frame, causing the SSB in the second half frame to be undetectable and its corresponding Type 0-PDCCH-CSS. It can also improve the detection speed of SSB and its corresponding Type 0-PDCCH-CSS and save UE access time.

[0098] Optionally, the transmission of SSBs can be restricted. For example, network devices can restrict the transmission of the first half of an SSB frame to avoid the problem of the second half of the frame being associated with the first half.

[0099] In the above implementation, by restricting the time domain position of the SSB sent by the network device, the problem of interference between the starting time domain positions of CORESET#0 corresponding to the same SSB index is avoided. This scheme is simple to implement and highly operable.

[0100] In conjunction with the first aspect, in some implementations of the first aspect, the starting temporal position of the first control resource set is determined based on the index of the first window and the first SSB. Wherein,

[0101] In one possible implementation, the first window is a burst set transport window (DBTW), and the starting time-domain position n0 of the first control resource set satisfies the following condition:

[0102]

[0103] Indicates the number of time slots within the first system frame.

[0104] O3*2 μ This indicates the number of time slots contained within O3ms, O3*2 μ =DBTW_slots, where DBTW_slots is the preset number of time slots occupied by the first SSB for transmission.

[0105] The O3 value is determined according to the DBTW, and takes the following values:

[0106] i represents the index of the first SSB.

[0107] M represents the time slot interval of the first control resource set corresponding to two adjacent SSBs in the first SSB.

[0108] Optionally, the value of M can be a preset value.

[0109] In the above implementation, the terminal device can determine the full transmission duration of the first SSB according to the first window, and adjust the parameter O value through the first window. The time domain position of CORESET#0 of the first SSB can be further determined by the O value, so that the starting time domain position of CORESET#0 starts from the time slot after the full transmission duration, avoiding position conflicts between Type0-PDCCHCSS and SSB.

[0110] In conjunction with the first aspect, in some implementations of the first aspect, the starting time domain position of the first control resource set is determined based on the first duration and the index of the first SSB.

[0111] In one possible implementation, the first duration is the number of time slots corresponding to the complete transmission of the first SSB, and the starting time domain position n0 of the first control resource set satisfies the following condition:

[0112]

[0113] O4*2 μ This indicates the number of time slots contained within O4ms, O4*2 μ =SSB_all,

[0114] The O4 value is determined based on the SSB_all value, and its possible values ​​are:

[0115] i represents the index of the first SSB.

[0116] M represents the time slot of the first control resource set corresponding to two adjacent SSBs in the first SSB.

[0117] Optionally, the value of M can be a preset value.

[0118] In the above implementation, the terminal device can determine the complete transmission duration of the first SSB based on the first duration, adjust the parameter O value through the first window, and further determine the time domain position of the first SSB CORESET#0 based on the O value, so that the starting time domain position of CORESET#0 starts from the time slot after the complete transmission duration, avoiding the conflict between the common search space and the position of the SSB.

[0119] In conjunction with the first aspect, in some implementations of the first aspect, when the subcarrier spacing of the first SSB is 480kHz, the DBTW_slots = 72ms, and when the subcarrier spacing of the first SSB is 960kHz, the DBTW_slots = 64ms.

[0120] In conjunction with the first aspect, in some implementations of the first aspect, when the subcarrier spacing of the first SSB is 480kHz, the value of O4 is 1ms when SSB_all = 32ms; when the subcarrier spacing of the first SSB is 960kHz, the value of O4 is 0.5ms when SSB_all = 32ms.

[0121] In conjunction with the first aspect, in certain implementations of the first aspect, the starting temporal domain position of the first control resource set is determined based on the first information and the index of the first SSB. Wherein,

[0132] M represents the time slot of the first control resource set corresponding to two adjacent SSBs in the first SSB.

[0133] Optionally, the values ​​of O and M can be preset values.

[0134] In the above implementation, the terminal device can determine the position of the uplink time slot based on the first information. When the time domain position of the CORESET#0 of the first SSB falls into the uplink time slot, the time domain position of the CORESET#0 of the first SSB is further determined according to the adjusted formula, so that the starting time domain position of the CORESET#0 of the first SSB avoids the uplink time slot, thus avoiding the extension of detection time caused by the collision.

[0135] In conjunction with the first aspect, in some implementations of the first aspect, when the subcarrier spacing of the first SSB is 480kHz, the DBTW_slots = 72ms, and the value of O3 is 2.25ms. However, if the uplink time slot is avoided, the value of O3 is 2.5ms. When the subcarrier spacing of the first SSB is 960kHz, the DBTW_slots = 64ms, and the value of O3 is 1ms. However, if the uplink time slot is avoided, the value of O3 is 1.25ms.

[0136] In one possible implementation, when the subcarrier spacing of the first SSB is 480kHz, SSB_all = 32ms and the value of O4 is 1ms. However, if considering avoiding uplink time slots, the value of O4 is 1.25ms. When the subcarrier spacing of the first SSB is 960kHz, when SSB_all = 32ms, the value of O4 is 0.5ms. Since there is no uplink time slot at 0.5ms for 960kHz, the value of O4 is 0.5ms.

[0137] Secondly, a time-domain location determination device is provided. This device can be a terminal device, or it can be a chip or circuit configured in a terminal device. This application does not limit the specific device.

[0138] The device includes: a first determining module, configured to determine the index of a first SSB, wherein the subcarrier spacing of the first SSB is greater than or equal to 120kHz; and a second determining module, further configured to determine the starting time-domain position of a first control resource set based on at least one of a first indication information, a first duration or a first window, first information, a first relationship, and a first delay, and the index of the first SSB, wherein the first indication information indicates the time-domain position of the first control resource set in the first half-frame or the second half-frame within a first system frame, the first duration includes the duration occupied by the first SSB for complete transmission within the first system frame, the first window is a preset duration occupied by the first SSB for transmission, the first information is the number of time slots available for uplink data transmission and the position of the time slots, the first relationship is the ratio of the subcarrier spacing of the first SSB to 120kHz, and the first delay is the access delay of the terminal device UE.

[0139] According to the scheme of this application, the starting time domain position of the first control resource set is determined based on at least one of the first indication information, the first duration or the first window, the first information, the first relationship, and the first delay, and the index of the first SSB. This enables the starting position of the first control resource set to be adapted to the subcarrier spacing of the high-frequency band, thereby making the starting time domain position of the first SSB CORESET#0 more accurate and improving the detection performance.

[0140] In conjunction with the second aspect, in some implementations of the second aspect, the subcarrier spacing of the first SSB is equal to 120 kHz, 480 kHz, or 960 kHz.

[0141] According to this technical solution, the subcarrier spacing of the first SSB is equal to 120kHz, 480kHz or 960kHz. Increasing the subcarrier spacing of the first SSB shortens the absolute time corresponding to each time slot, reduces the latency, and helps to reduce the initial access latency of the terminal device.

The configuration information sent by the network device can indicate the parameters of one or more rows in the table. For example, the configuration information can be an index in the table that indicates the temporal location parameter information of the first resource.

[0256] For example, in the embodiments described below, the temporal location parameter information of the first resource can be an M / O table. The network device sends the index of the M / O table as configuration information to specifically indicate the temporal location parameter information of the first resource corresponding to the first SSB.

[0266] In one possible implementation, the temporal location parameter information of the first resource can be predefined or stored in the form of a table in the communication device provided in the fifth aspect or the communication device provided in the sixth aspect. The configuration information sent by the communication device on the network device side can indicate the parameters of one or more rows in the table. For example, the configuration information can be an index in the table indicating the temporal location parameter information of the first resource.

[0267] For example, in the embodiments described below, the temporal location parameter information of the first resource can be an M / O table, which is used by the communication device on the network device side to send the index of the M / O table as configuration information to specifically indicate the temporal location parameter information of the first resource corresponding to the first SSB. Of course, the communication device on the network device side can also directly send the temporal location parameter information of the first resource corresponding to the first SSB in the configuration information, which is not limited in this application.

[0268] In this embodiment, any M / O table or CORESET#0 parameter configuration form (not shown) from the following embodiments can be directly referenced as parameter information in this embodiment. Additionally, embodiments related to these M / O tables can also be incorporated into this embodiment; for brevity, please refer to the description of the embodiments below, which will not be repeated here.

[0269] In one possible implementation, after the communication device used as the terminal device searches for the SSB, it parses the PBCH of the SSB to obtain the MIB information, and obtains the time-domain location parameters of the first control resource set CORESET#0 based on the MIB information.

[0270] In one possible implementation, this configuration information can also be carried in other signaling.

[0271] For example, the configuration information can be carried in an SIB, such as system information blocks like SIB1, SIB2, SIB3 to SIBx, or a new SIB introduced in RedCap UE, where x is a positive integer greater than or equal to 2.

[0272] For example, the configuration information can also be carried in downlink control information (DCI), such as in the DCI for scheduling SIB1.

[0273] According to the above scheme, the terminal device can accurately determine the time domain location of the control resource set under the high-frequency subcarrier spacing (e.g., 120kHz, 480kHz, 960kHz, etc.).

The 5G mobile communication system can be either non-standalone (NSA) or standalone (SA) networking.

[0295] The technical solutions provided in this application can also be applied to machine-type communication (MTC), long-term evolution-machine (LTE-M) technology, device-to-device (D2D) networks, machine-to-machine (M2M) networks, Internet of Things (IoT) networks, or other networks. Among these, IoT networks may include, for example, vehicle-to-everything (V2X) networks. The communication methods in V2X systems are collectively referred to as vehicle-to-X (V2X), where X can represent anything. For example, V2X may include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, or vehicle-to-network (V2N) communication, etc.

[0296] The technical solutions provided in this application can also be applied to future communication systems, such as sixth-generation (6G) mobile communication systems. This application does not limit the application in this regard.

[0297] In the embodiments of this application, the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user apparatus.

[0298] Terminal devices can be devices that provide voice / data connectivity to users, such as handheld devices and in-vehicle devices with wireless connectivity. Currently, some examples of terminals include: mobile phones, tablets, computers with wireless transceiver capabilities (such as laptops and PDAs), mobile internet devices (MIDs), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving cars, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes (e.g., home appliances such as televisions, smart boxes, game consoles), cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). Handheld devices, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks, or terminal devices in future evolved public land mobile networks (PLMNs) with wireless communication capabilities.

[0299] Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction. Broadly defined, wearable smart devices include those with comprehensive functions, large sizes, and the ability to perform complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses. They also include devices focused on a specific application function that require the use of other devices, such as smart bracelets and smart jewelry for vital sign monitoring.

[0300] Furthermore, terminal devices can also be terminal devices in Internet of Things (IoT) systems. IoT is an important component of future information technology development. Its main technical characteristic is connecting objects to networks through communication technologies, thereby achieving intelligent networks that enable human-machine interconnection and machine-to-machine interconnection. IoT technology can achieve massive connectivity, deep coverage, and low power consumption at the terminal level through technologies such as narrowband (NB).

[0301] In this application embodiment, the terminal device can also be a vehicle or a complete vehicle, which can communicate through the Internet of Vehicles, or it can be a component located inside the vehicle (e.g., placed inside the vehicle or installed inside the vehicle), namely, an on-board terminal device, an on-board module, or an on-board unit (OBU).

[0302] In addition, terminal devices may also include sensors such as smart printers, train detectors, and gas stations. Their main functions include collecting data (for some terminal devices), receiving control information and downlink data from network devices, and sending electromagnetic waves to transmit uplink data to network devices.

[0303] In this embodiment of the application, the network device can be any device with wireless transceiver capabilities. This equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in a wireless fidelity (WiFi) system. It can also be a gNB in ​​a 5G system, such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU), or a distributed unit (DU), or a base station in a next-generation communication 6G system.

[0304] In some deployments, a gNB may include a centralized unit (CU) and a distribution unit (DU). The gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU handles non-real-time protocols and services, implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU handles physical layer protocols and real-time services, implementing radio link control (RLC), medium access control (MAC), and physical (PHY) layer functions. The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can be considered to be sent by the DU, or by both the DU and CU. It is understood that network devices can be devices that include one or more of the following: CU nodes, DU nodes, and AAU nodes. In addition, the CU can be classified as a network device in the radioaccess network (RAN) or as a network device in the core network (CN), and this application does not limit it in this way.

[0305] Network equipment provides services to cells. Terminal devices communicate with cells through transmission resources (e.g., frequency domain resources, or spectrum resources) allocated by the network equipment. The cell can belong to a macro base station (e.g., macro eNB or macro gNB) or to a base station corresponding to a small cell. Small cells can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0306] Figure 1 This is a schematic diagram of a communication system 100 applicable to the communication method of embodiments of this application. For example... Figure 1 As shown, the communication system 100 may include one or more network devices, such as Figure 1 The network device 110 shown; the communication system may also include one or more terminal devices, such as Figure 1The terminal devices 121-125 are shown. Network devices and terminal devices can communicate via a wireless link. Each communication device, such as network device 110 or terminal devices 121-125, can be configured with multiple antennas. For each communication device in this communication system, the configured multiple antennas may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. Therefore, the communication devices in this communication system, and between network device 110 and terminal devices 121-125, can communicate via multi-antenna technology.

[0307] In one possible implementation, terminal devices can also communicate via technologies such as device-to-device (D2D), vehicle-to-everything (V2X), or machine-to-machine (M2M), for example... Figure 1 The terminal devices 124 and 125 shown can communicate with each other. This application does not limit the communication method between terminal devices.

[0308] It should be understood that Figure 1 This is a simplified illustration for ease of understanding only. The communication system may also include other network devices or other terminal devices. Figure 1 It was not drawn in the middle.

[0309] It should also be understood that Figure 1 This is merely one application scenario of an embodiment of this application. The method provided in this application is not limited to communication between network devices and terminal devices, but can also be applied to communication between terminal devices, etc. This application does not limit the application scenario of this method.

[0310] Figure 2 This is a schematic diagram of a communication method 200 applicable to embodiments of this application. Figure 2 The method 200 shown can be derived from Figure 1 The network devices and terminal devices shown perform the following actions: Figure 2 The method 200 shown can be applied to the method in the embodiments below. S210, the network device determines configuration information, which is used to indicate the time-domain location parameter information of the first resource corresponding to the first SSB.

[0311] The first resource can be the first set of control resources corresponding to the first SSB. Optionally, the configuration information can be carried in a MIB message.

[0312] In one possible implementation, the temporal location parameter information of the first resource is used by the terminal device to determine the temporal location of CORESET#0 of the first SSB. For example, the temporal location parameter information of the first resource can be predefined or stored in a table format between the terminal device and the network device. The configuration information sent by the network device can indicate parameters in one or more rows of the table. Specifically, the configuration information can be a table index. For instance, as described below, the temporal location parameter information of the first resource can be an M / O table, and the network device sends the index of the M / O table as configuration information to specifically indicate the temporal location parameter information of the first resource corresponding to the first SSB. Of course, the network device can also directly send the temporal location parameter information of the first resource corresponding to the first SSB in the configuration information; this application does not limit this.

[0313] It is understandable that CORESET#0 requires parameter configuration. The terminal device UE can further obtain the time domain information of CORESET#0 through the configured parameters. The M / O table can be a form of the configuration parameters.

[0314] It should be noted that in this embodiment, the M / O table can be any type of table in the following embodiments, or it can be a CORESET#0 parameter configuration form not shown in this embodiment. Any M / O table or CORESET#0 parameter configuration form not shown in the following embodiments can be directly referenced in this embodiment as parameter information. Furthermore, embodiments related to these M / O tables can also be incorporated into this embodiment; for brevity, please refer to the description of the embodiments below, which will not be repeated here.

[0315] S220, the network device sends the configuration information to the terminal device, and the terminal device receives the configuration information accordingly.

[0316] Network devices can indicate the temporal location parameter information of the first resource through configuration information. In one implementation, the configuration information is carried in the MIB. That is, after the terminal device finds the SSB, it parses the PBCH of the SSB to obtain the MIB information and obtains the temporal location parameters of the first control resource set CORESET#0 based on the MIB information.

[0317] Optionally, the configuration information can also be carried in other signaling. For example, the configuration information can be carried in SIBs, such as SIB1, SIB2, SIB3 to SIBx system information blocks, or SIBs newly introduced in RedCap UEs, where x is a positive integer greater than or equal to 2.

[0318] Optionally, the configuration information can also be carried in downlink control information (DCI), for example, in the DCI of scheduling SIB1.

[0319] S230, the terminal device determines the time domain location of the first resource based on the configuration information.

[0320] In one possible implementation, the terminal device can determine the time-domain location parameter information of the first resource based on the configuration information. For example, it can obtain the indication information of the M / O table of the time-domain location of CORESET#0, and then determine the time-domain location of CORESET#0 based on the indication information.

[0321] For example, the indication information of the M / O table for the time domain position of CORESET#0 is the index of the M / O table. The terminal device can determine the corresponding parameter O value and M value based on the index information, and further determine the time domain position of CORESET#0 of the first SSB based on the O value and M value.

[0322] The above implementation method can accurately determine the time domain location of the control resource set under high-frequency subcarrier spacing (e.g., 120kHz, 480kHz, 960kHz, etc.).

[0323] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0324] To facilitate understanding of the embodiments of this application, the terminology involved in the embodiments of this application will be briefly introduced below.

[0325] 1. Licensed frequency bands and unlicensed frequency bands

[0326] New Radio (NR) divides frequency bands into two main parts: FR1 (Frequency Range 1) and FR2. FR1 mainly refers to the 450MHz–6GHz bandwidth, while FR2 mainly refers to the 24.25GHz–52.6GHz bandwidth. For example, the FR1 band can support sub-carrier spacing (SCS) of 15kHz and 30kHz; the FR2 band can support SCS of 60kHz, 120kHz, and 240kHz or wider sub-carrier spacing. In addition, the 52.6GHz–71GHz band (above 52.6GHz) is also included in the scope of use for the next 5G mobile communication system. For this band, there are both licensed and unlicensed bands. Unlicensed bands, also known as shared bands, do not require licensing for use.

[0327] In this application embodiment, the frequency band of the network device and the terminal device may include low frequency band and high frequency band. In some scenarios, the frequency band may be a licensed frequency band, and in some scenarios, the frequency band may be an unlicensed frequency band. This application embodiment does not limit this.

[0328] 2. Synchronization signal / physical broadcast channel block (SSB)

[0329] SSB, also known as the Synchronization Signal / Physical Broadcast Channel (PBCH) block, consists of the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcasting Channel (PBCH), occupying four orthogonal frequency division multiplexing (OFDM) symbols in the time domain.

[0330] Figure 3This is a schematic diagram illustrating the contents of an SSB symbol provided in an embodiment of this application. The SSB bandwidth is 20 resource blocks (RBs), containing 240 subcarriers. The first symbol carries a PSS, which includes 127 subcarriers, meaning the PSS sequence length is 127. The PSS occupies only the middle portion of the SSB frequency domain, with no other data or control information transmitted on either side. The second and fourth symbols are the physical broadcasting channel (PBCH), primarily carrying system information. The third symbol carries both the PBCH and the SSS, with the SSS sequence length being the same as the PSS (127), and both occupying 127 resource elements (REs) in the middle of the SSB frequency domain. The PBCH is transmitted using 48 REs on each side of the SSS, with intervals of 8 and 9 REs between the SSS and PBCH, respectively.

[0331] The frequency domain bandwidth of SSB under different subcarrier spaces (SCS) is shown in Table 1.

[0332] Table 1

[0333] SSB SCS(KHz) SSB frequency domain bandwidth (20 RBs) (MHz) 15KHz 3.6 30kHz 7.2 120kHz 28.8 240kHz 57.6

[0334] SSBs can be divided into cell-defining SSBs (CD-SSBs) and non-cell-defining SSBs (NCD-SSBs). If an SSB is associated with remaining minimum system information (RMSI), such an SSB is called a CD-SSB. A CD-SSB corresponds to one cell, which is identified by a unique NR cell global identifier (NCGI).

[0335] The PBCH carries master information block (MIB) information. The MIB information indicates whether control resource set (CORESET) #0 exists. If the MIB indicates that CORESET #0 exists, it means that the SSB is a CD-SSB. The terminal device can determine CORESET #0 and Type 0-physical downlink control channel common search space (Type 0-PDCCH CSS) through the parameter (pdcch-ConfigSIB1) in the MIB information. CORESET #0 is the CORESET associated with Type 0-PDCCH CSS. The terminal device listens for and schedules the PDCCH of system information block 1 (SIB1, also known as remaining minimum system information (RMSI)) on CORESET #0. Specifically, the PDCCH is used to schedule the physical downlink shared channel (PDSCH) carrying SIB1. The Type0-PDCCH CSS is also known as search space 0, search space set 0, or search space set with ID 0. If the MIB indicates that CORESET#0 does not exist, it means that the SSB is NCD-SSB, that is, NCD-SSB is not associated with SIB1 / RMSI.

[0336] One of the functions of the SSB is cell access. Terminal devices can receive MIB information through the SSB to obtain the SIB1 associated with the SSB and access the cell. Since the SSB includes PSS, SSS, PBCH, and DMRS, it can also be used by terminal devices to perform time-frequency tracking (or time-frequency synchronization), beam management, radio resource management (RRM) measurements, radio link monitoring (RLM) measurements, and channel state information (CSI) measurements.

[0337] CORESET#0 is an example of a control resource set. Control resource set can also be represented by other terms, and this application does not limit this.

[0338] 3. Control resource set (CORESET) and search space.

[0339] The control resource set is a collection of resources used to transmit downlink control information. It can also be called a control resource region or a physical downlink control channel resource set.

[0340] Because NR has a large system bandwidth (up to 100MHz in frequency range 1 (FR1) and up to 400MHz in frequency range 2 (FR2), NR encapsulates information such as the frequency band occupied by the PDCCH in the frequency domain and the number of OFDM symbols occupied in the time domain in the CORESET, and encapsulates information such as the OFDM symbol index at the start of the PDCCH and the PDCCH listening period in the search space. PDCCH configuration includes CORESET configuration and search space configuration. Based on CORESET and search space, candidate PDCCH resources can be determined. The control resource set can include time-frequency resources; for example, in the frequency domain, it can be a bandwidth, or one or more sub-bands; in the time domain, it can be one or more OFDM symbols. A control resource set can be continuous or discontinuous resources in the frequency domain; for example, in the frequency domain, the control resource set includes continuous RBs or discontinuous RBs. One or more search spaces constitute a search space set. Unless otherwise specified, search space and search space set are interchangeable and have the same meaning.

[0341] For network devices, the control resource set can be understood as the set of resources that may be used to send PDCCH; for terminal devices, the resources corresponding to the search space of each terminal device's PDCCH belong to the control resource set. In other words, network devices can determine the resources used to send PDCCH from the control resource set, and terminal devices can determine the search space of PDCCH based on the control resource set.

[0342] 4. Synchronization raster (synch raster)

[0343] Terminal equipment can scan the frequency location information of SSBs using a synchronization grid, which represents a series of frequencies available for transmitting SSBs. When deploying a base station, cells need to be established, and each cell requires a specific SSB. The frequency location corresponding to each SSB is the synchronization grid location. The introduction of the synchronization grid concept primarily aims to ensure that terminal equipment performs corresponding searches at specific frequency locations during cell search, avoiding the uncertainty of blind searches that lead to excessively long access delays and energy consumption. 3GPP defines certain frequencies as synchronization grids. CD-SSBs are located within the synchronization grid, while NCD-SSBs may or may not be located within it. The synchronization grid represents an absolute frequency location. If an SSB exists at a frequency location within the synchronization grid, it corresponds to the frequency location of the 121st subcarrier out of the 240 subcarriers included in the SSB.

[0344] During initial access, the UE must first select a cell. The UE will search for an SSB on the synchronization grid. If a CD-SSB is found on the synchronization grid, the UE may select the cell corresponding to that CD-SSB as the initial access cell. In addition, the UE will receive the RMSI (i.e., SIB1) associated with that CD-SSB.

[0345] 5. Reusable styles for SSB and CORESET#0

[0346] SSB and CORESET#0 each correspond to a time-frequency resource. Based on the distribution of SSB and CORESET#0, the multiplexing patterns of SSB and CORESET#0 are divided into three types. Figure 4 This is a schematic diagram illustrating the reuse style of SSB and CORESET#0 provided in the embodiments of this application. For example... Figure 4 As shown, Pattern 1 is time-division multiplexing (in this case, the frequency domain length of CORESET#0 is always greater than that of SSB, and the frequency domain range includes SSB), while Patterns 2 and 3 are frequency-division multiplexing (CORESET#0 is in the same system frame as SSB). The difference between Patterns 2 and 3 is that, in the time domain, CORESET#0 in Pattern 2 is positioned earlier than SSB, and CORESET#0 is in the same time slot as SSB or the previous time slot).

[0347] In this embodiment, time-division multiplexing is used as an example for illustration.

[0348] Currently, in NR systems, due to the large system bandwidth (maximum 400MHz), if the PDCCH still occupies the entire bandwidth, it not only wastes resources and increases the complexity of blind detection, but also prevents some UEs from receiving signals across the entire bandwidth. Furthermore, to increase system flexibility, the starting position of the PDCCH in the time domain can be configured. In this case, the UE needs to know the PDCCH's position in both the frequency and time domains to successfully decode it. To obtain the RMSI transmitted on the PDSCH, the UE must first find the CORESET#0 (the PDCCH physical resource corresponding to Type 0CSS) that schedules the PDSCH. After searching the SSB and reading the MIB, the UE can find CORESET#0 based on the relative relationship between CORESET#0 and the SSB. CORESET#0 is part of the Initial BWP configuration information and is provided to the UE through the MIB message (PDCCHconfigSIB1). The UE obtains the SIB1 scheduling information from CORESET#0, thus completing the initial access. Before the RRC connection is established, CORESET#0 already exists. The UE needs to receive the SIB1 scheduling information through CORESET#0. CORESET#0 can be configured by some predefined procedures and predefined parameters, for example, in section 7.3.2.2 of 3GPP TS 38.211.

[0349] The UE queries the predefined tables (tables 13-1 to 13-10 of 3GPP TS 38.213) through the MIB message containing MIB pdcch-ConfigSIB1, calculates the time and frequency resources of CORESET#0 based on SSB, and obtains the scheduling information of SIB1 from CORESET#0 to help the UE complete the initial access.

[0350] Specifically, the relative relationship between CORESET#0 and SSB is determined through MIB messages, including sub-carrierSpacing Common (RMSI SCS), SSB Subcarrier Offset (the lower four bits of kssb), and PDCCH ConfigSIB1. PDCCH ConfigSIB1 consists of 8 bits. Separating the high 4 bits and low 4 bits yields two indices, each ranging from 0 to 15. The high 4 bits, when consulted in 3GPP TS 38.213 tables 13-1 to 13-10, provide the multiplexing pattern of CORESET#0, the number of symbols (time domain length), the number of RBs (frequency domain length), and the RB offset (frequency domain offset). The low 4 bits, when consulted in tables 13-11 to 13-15, provide information about Search Space 0 (SFN, slot index, start symbol, etc.).

[0351] The UE retrieves the corresponding parameter values ​​from the tables (Tables 13-11 to 13-15 of 3GPP TS 38.213), and then calculates the time-domain information of CORESET#0 according to the formula. According to the description in 3GPP TS 38.213, for Pattern 1, the UE listens continuously for 2 time slots starting from time slot n0.

[0352] The expression for n0 is shown in Formula 1 below, and the parameters M and O can be determined from Table 13-11 (FR1) or 13-12 (FR2).

[0353] For example, as shown in Table 2 below, Table 2 is Table 13-12.

[0354]

[0355] Where 0 represents the offset of CORESET#0 corresponding to SSB INDEX=0 relative to the start position of even-numbered frames, in milliseconds. Subcarrier spacing SCS=2 μ *15kHz, subcarrier spacing is 120kHz, μ value is 3, since 1ms contains 2 μ Time slot, O*2 μ This indicates the number of time slots contained in O ms. In FR1, O can be 0, 2, 5, or 7; in FR2, O can be 0, 2.5, 5, or 7.5. O indicates the CORESET#0 corresponding to the first SSB, with the CORESET#0 corresponding to other SSBs listed sequentially. M represents the interval between two adjacent SSBs corresponding to CORESET 0, which can be understood as the search range, in time slots. In the table, there is another column between O and M, indicating the number of search spaces contained in one time slot, denoted as N, where i represents the index value of the SSB, corresponding to 0-L. max -1.

[0356] Table 2

[0357]

[0358]

[0359] With the evolution of new radio (NR) technology, the available frequency bands are constantly increasing, and higher subcarrier spacing has been proposed, such as 480kHz and 960kHz. However, the parameter values ​​predefined in the current protocol are not applicable to high-frequency subcarrier spacing.

[0360] Specifically, for example, when O=7.5 and M=1 in Table 2, 480kHz corresponds to 2 μ =32, After substituting into the formula, the result is O*2. μ =7.5 * 32 = 240 slots. Therefore, for SSB_index = 0 at 480kHz, the starting offset is 240 slots, and it has a total of 320 slots. Within a system frame, the absolute time length of a system frame is 10ms, and it is divided into two half-frames with a half-frame time of 5ms. Since SSBs are only transmitted within a half-frame, the offset here has exceeded the half-frame, so the UE cannot detect the SSBs that have already been transmitted in the first half-frame in time. This causes the UE to wait a long time to detect SSBs, affecting the UE's access time.

[0361] Therefore, how to design the corresponding parameters of the time-frequency resource information of the control resource set for the high-frequency subcarrier spacing has become an urgent problem to be solved.

[0362] In view of this, this application provides a method and apparatus for determining the time-domain location, which can provide parameters of the corresponding control resource set for the SSB of the high-frequency subcarrier spacing, thereby accurately determining the time-domain location of the control resource set.

[0363] The following will describe in detail, with reference to the accompanying drawings, a method and apparatus for determining time-domain location provided in the embodiments of this application.

[0364] Figure 5 This is a schematic block diagram illustrating a method for determining time-domain location provided in an embodiment of this application. Figure 5 The method 500 shown can be derived from Figure 1 The terminal devices and network devices shown are used for execution.

[0365] The first SSB is an example of an SSB, and the first SSB includes multiple SSBs; the first control resource set is an example of a control resource set. This application embodiment uses the first SSB and the first control resource set for illustrative purposes, and does not limit the scope of the application.

[0366] S510, the terminal device determines the index of the first SSB, the subcarrier spacing of the first SSB is greater than or equal to 120kHz;

[0367] In this process, the terminal device receives the first SSB sent by the network device and determines the index of the first SSB, which can be understood as the time-domain location where the first SSB was sent.

[0368] In one possible implementation, the subcarrier spacing of the first SSB can be 120 kHz, 480 kHz, or 960 kHz.

[0369] In one possible implementation, the subcarrier spacing of the first SSB can be greater than 960 kHz.

[0370] S520, the terminal device determines the starting time domain position of the first control resource set based on at least one of the first instruction information, the first duration or the first window, the first information, the first relationship, and the first delay, and the index of the first SSB.

[0371] Through this technical solution, the terminal device combines at least one of the first indication information, the first duration or the first window, the first information, the first relationship, and the first delay with the index of the first SSB to determine the starting time domain position of the first control resource set, so that the starting position of the first control resource set can meet the subcarrier spacing requirements of the high-frequency band.

[0372] The starting time domain position of the first control resource set can also be understood as the time domain position of CORESET# 0 corresponding to the first SSB, which is explained uniformly here.

[0373] The first instruction information, the first duration or the first window, the first information, the first relationship, and the first delay are described in detail below.

[0374] I. First Instruction Information

[0375] In this embodiment of the application, the first indication information indicates the temporal location of the first control resource set in the first system frame, either the first half frame or the second half frame.

[0376] Figure 6 This is a schematic diagram showing the temporal location of the SSB and its corresponding CORESET#0 within a system frame when N=2, M=1, and O=0, using 480kHz as an example. Figure 6 As shown, the absolute time length of a system frame is 10ms, and it is divided into two half-frames with a half-frame time of 5ms each. Figure 6 As shown in the first and second half frames, the distinction between the first and second half frames can be indicated by the first indication information.

[0377] It should be understood that the SSB index numbering rule is 0-L. max -1. For example, such as Figure 6 As shown, when the subcarrier spacing of the SSB is 480kHz, for L max=64. The first half of the frame and the second half of the frame use the same numbering rule. Therefore, the SSB index of the first half of the frame and the second half of the frame are both 0-63. When calculating the time domain position of CORESET#0 according to Formula 1, the time domain position n0 value of the SSB CORESET#0 calculated by the same SSB index is the same. That is to say, the CORESET#0 associated with the same SSB index in the first half of the frame and the second half of the frame will correspond to the same starting slot n0. This will cause the starting slot n0 of the SSB CORESET#0 sent in the second half of the frame to fall in the first half of the frame.

[0378] For example, such as Figure 6 As shown, when i = 0, according to Formula 1, the starting slot n0 corresponding to CORESET#0 associated with the first SSB in the first half-frame is shown as the search space of the solid-line box SSB0 in the figure. The starting slot n0 corresponding to CORESET#0 associated with the first SSB in the second half-frame will fall in the same position, as shown in the figure. Figure 6 As shown by the dashed arrow, when performing detection based on the calculation results, it is impossible to detect the first SSB and its corresponding Type 0 physical downlink control channel common search space (Type 0-PDCCHCSS) in the second half of the frame. The correct position of the starting slot n0 corresponding to CORESET#0 associated with the first SSB in the second half of the frame is shown in the dashed box SSB0 search space in the figure. Since the SSB and its corresponding Type 0-PDCCH CSS in the second half of the frame cannot be detected based on this calculation result, the detection of the SSB and its corresponding Type 0-PDCCH CSS can only continue in the next detection cycle, affecting the search of the SSB and its corresponding Type 0-PDCCH CSS, increasing the detection time, and affecting the UE access process.

[0379] Therefore, by combining the first indication information, it can be determined whether the first SSB is in the first half-frame or the second half-frame, avoiding the association between the starting n0 timeslot position of CORESET#0 calculated by the SSB in the first half-frame and the second half-frame. Thus, it can be detected in the corresponding position within the half-frame where the SSB is located in the same time domain, accurately obtaining the timeslot position of CORESET#0 associated with the SSB, and saving UE access time.

[0380] It should be understood that the first indication information is just one example of indication information and is only used as an example. Specifically, the first indication information may be half-frame bits, the time slot index where the first SSB is located, or other information that can indicate whether the first SSB is sent in the first half-frame or the second half-frame. This application embodiment does not limit this.

[0381] II. First duration or first window

[0382] In this embodiment, both the first duration and the first window are used to describe the time length occupied by sending the first SSB. The first duration refers to the actual time occupied by all SSBs included in the first SSB being completely sent within the first system frame. The first window is the time preset by the network device for sending all SSBs included in the first SSB. Within the first window, the first SSB is sent. The first window can be understood as being greater than the first duration, that is, greater than the actual time occupied by sending the first SSB, or equal to the time length occupied by sending the first SSB. If it is less than the first duration, the unsent SSBs will not be sent.

[0383] It should be understood that the first duration is merely an illustrative example and may also be other information indicating the actual length of time occupied by sending the first SSB. This application does not limit this.

[0384] It should be understood that the first window is only an illustrative example and may also be referred to as the second duration or the second time. For example, the first window may be a discovery burst transmission window (DBTW) or other information used to indicate the length of time occupied by the first SSB transmission. This application embodiment does not limit this.

[0385] Based on the first window or the first duration, the time domain position of CORESET#0 can be restricted to after the first SSB is sent, that is, after all SSBs have been sent, to avoid conflicts between Type0-PDCCH CSS and SSB.

[0386] III. First Information

[0387] The first piece of information is the information about the time slots that can be used to transmit uplink data, specifically the location and number of the uplink time slots.

[0388] Figure 7 This diagram illustrates the time slot locations corresponding to different subcarrier intervals within a half-frame of a system with a subcarrier interval of 120 kHz. Figure 7As shown, in the 120kHz CaseD design, uplink slot positions are reserved. Specifically, the uplink slot positions within a 5ms half-frame are {8,9,18,19,28,29,38,39}. Using a subcarrier spacing of 120kHz as the reference slot, the corresponding slot positions for subcarrier spacings of 480kHz and 960kHz are {4,9,14,19}. Specifically, as... Figure 7 As shown, within a 5ms half-frame, the uplink slot positions corresponding to a subcarrier spacing of 480kHz are {32-39, 72-79, 112-119, 152-159}, and the uplink slot positions corresponding to a subcarrier spacing of 960kHz are {64-79, 144-159, 224-239, 304-319}.

[0389] In this embodiment of the application, in order to avoid the time domain position n0 of CORESET#0 from conflicting with the uplink time slot, the starting value needs to avoid the uplink slot position. That is, the uplink slot positions to be avoided when the subcarrier spacing is 480kHz are {32-39, 72-79, 112-119, 152-159}, and the uplink slot positions to be avoided when the subcarrier spacing is 960kHz are {64-79, 144-159, 224-239, 304-319}.

[0390] Based on this first piece of information, the time domain position of CORESET#0 can avoid the position of the uplink time slot, thereby preventing the time domain position of CORESET#0 from falling into the uplink time slot and avoiding the extension of detection time caused by the collision.

[0391] IV. First Delay

[0392] In this embodiment of the application, the first delay refers to the access delay of the terminal device.

[0393] For example, when O>=5, if the starting position of the associated CORESET#0 is configured in the second half of the frame for the first SSB transmitted in the first half of the frame, the UE access process time will be lengthened, impacting performance and negating the low latency advantage gained from reducing the absolute time per slot using 480kHz and 960kHz. Therefore, to save access latency, the value of O>=5 can be removed or it can be considered no longer used.

[0394] It should be understood that the first delay is an optional solution in any embodiment of this application, and the embodiments of this application do not limit it.

[0395] V. First Relationship

[0396] In this embodiment of the application, the first relationship refers to the ratio of the subcarrier spacing of the first SSB to the subcarrier spacing of 120kHz relative to the subcarrier spacing of 120kHz. Based on this ratio, the O value corresponding to the subcarrier spacing of the first SSB can be scaled proportionally based on the O value corresponding to 120kHz in FR2-1 of TS-38.213-Table 13-12.

[0397] It should be understood that, based on the first relationship and the time domain position of the first control resource set corresponding to 120kHz, the O value of the first SSB is scaled, and the parameter O value and M value are further determined according to the first indication information, the first duration or the first window, and the first information. The time domain position of the first SSB CORESET#0 can be further determined by the O value and M value and the adjusted formula for calculating the time domain position of the first control resource set.

[0398] It should be understood that, considering that the time domain position of the first control resource set corresponding to 120kHz has already avoided the uplink time slot, the time domain position of CORESET#0 corresponding to the first SSB after scaling the O value based on the time domain position of the first control resource set corresponding to 120kHz also avoids the uplink time slot.

[0399] Through this technical solution, the terminal device combines at least one of the first indication information, the first duration or the first window, the first information, the first relationship, and the first delay with the index of the first SSB to determine the starting time domain position of the first control resource set, so that the starting position of the first control resource set can meet the subcarrier spacing requirements of the high-frequency band.

[0400] In one implementation, the terminal device can determine the starting time-domain position of the first control resource set based on the first instruction information and the index of the first SSB.

[0401] Specifically, based on the first indication information, the terminal device can determine whether the transmission position of the first SSB is in the first half of the system frame or the second half of the system frame. Then, when determining the first control resource set, it can distinguish whether the starting time domain position of CORESET#0 corresponding to the same SSB index is in the first half of the frame or the second half of the frame, so as to avoid the SSB of the second half of the frame being associated with the time slot of the first half of the frame, which would result in the inability to detect the SSB of the second half of the frame and its corresponding Type 0 - Physical Downlink Control Channel Synchronization Information Block Type0 - PDCCH CSS.

[0402] Optionally, the first indication information can be half-frame bits n hfThe time slot offset of this half-system frame can be increased in the O value, i.e., the O1 value. In other words, due to the existence of the time slot offset, the O values ​​in Table 2 can be updated, and the updated O value is represented by O1. Specifically, the starting time domain position of the first control resource set can be determined according to the following formula 2:

[0403] Formula 2

[0404] Wherein, n0 represents the temporal location of the first control resource set.

[0405] The value of O1 is based on the n hf It is determined that the value can be:

[0406] in, This indicates the number of time slots within the first system frame. It represents the absolute time of half a system frame.

[0407] O1*2 μ This indicates the number of time slots contained within O1ms.

[0408] half-frame bits n hf This indicates whether the temporal location of the first control resource set is in the first half-frame or the second half-frame within the first system frame. For example, half-frame bits n hf The value of n can be 0 or 1. Optionally, when n hf When the value of n is 0, it indicates that the first control resource set is located in the first half of the frame. hf When the value is 1, it indicates that the first control resource set is located in the second half of the frame.

[0409] i represents the index of the first SSB.

[0410] O represents the offset of the first control resource set relative to the start position of even-numbered frames when the index value of the first SSB is 0. The value of O is a preset value, as shown in Table 2.

[0411] M represents the time slot interval of the first control resource set corresponding to two adjacent SSBs in the first SSB. The value of M can be a preset value. For example, the value of M can be referred to the M value in Table 2.

[0412] For example, a system frame can be 10ms. It can be 5ms.

[0413]

[0414] It should be noted that the updated O1 value can directly replace the O value in Table 2, but for the sake of simplicity, it is not shown here.

[0415] Alternatively, Formula 2 can also be expressed as:

[0416] or

[0417]

[0418] Optionally, when the first indication information is half a frame bit n hf The time slot offset of this half-system frame can be increased in Formula 1, i.e. Formula 3.

[0419] The starting time domain position can be determined according to the following formula 3:

[0420]

[0421] It should be understood that in the above implementation, the values ​​of O and M can be directly taken from the values ​​in Table 2, where the meanings of the same parameters are the same as those in Formula 1 and Formula 2, and will not be repeated here.

[0422] It should be noted that by adjusting the values ​​of parameters O and M based on the half-frame bit pair or by adjusting the time-domain position formula of the first control resource set, the starting time-domain position of CORESET#0 corresponding to the same SSB index can be distinguished as being in the first or second half-frame. This avoids the situation where the SSB of the second half-frame is associated with the time slot of the first half-frame, causing the SSB of the second half-frame to be undetectable and its corresponding Type 0-Physical Downlink Control Channel Synchronization Information Block Type0-PDCCH-CSS. It can also improve the detection speed of SSB and its corresponding Type0-PDCCH-CSS and save UE access time.

[0423] Optionally, when the first indication information is the slot index of the first SSB... id The time slot offset of this half-system frame can be increased in the O value, i.e., the O2 value. In other words, due to the existence of the time slot offset, the O value in Table 2 can be updated, and the updated O value is represented by O2.

[0424] The starting time domain position can be determined according to the following formula 4:

[0425]

[0426] The O2 value is based on the slot id It is determined that the value can be:

[0427] It should be understood that k is based on the slot. id Determined, used to indicate whether the temporal location of the first control resource set is in the first half-frame or the second half-frame.

[0428] The values ​​of O and M can be preset values. For example, you can refer to the values ​​of O and M in Table 2.

[0429] For example, a system frame can be 10ms. It can be 5ms.

[0430]

[0431] For example, the value of k can be...

[0432] It should be understood that the meanings of the same parameters are the same as those in Formula 1 and Formula 2, and will not be repeated here.

[0433] It should be noted that the updated O2 value can directly replace the O value in Table 2, but for the sake of simplicity, it is not shown here.

[0434] Optionally, Formula 4 can also be expressed as

[0435] or

[0436]

[0437] Optionally, when the first indication information is the slot index of the first SSB... id The time slot offset of this half-system frame can be added in the formula, i.e., Formula 5.

[0438] The starting time domain position can be determined according to the following formula 5:

[0439]

[0440] It should be understood that in the above implementation, the values ​​of O and M can be directly taken from the values ​​in Table 2, and the meanings of the same parameters in the formula are the same as those in Formula 1 and Formula 2, which will not be elaborated here.

[0441] According to the above scheme, the terminal device can determine whether the time domain position of the first SSB transmission is in the first half frame or the second half frame based on the first indication information. This avoids the SSB in the second half frame being associated with the time slot of the first half frame, which would prevent the detection of the SSB in the second half frame and its corresponding Type 0-Physical Downlink Control Channel Synchronization Information Block Type 0-PDCCH-CSS. It can also improve the detection speed of SSB and its corresponding Type 0-PDCCH-CSS and save UE access time.

[0442] In one possible implementation, the transmission of SSBs can be directly restricted. For example, the network device can restrict the transmission of SSBs in the first half of the frame, thus avoiding the problem of the second half of the frame being associated with the first half. In this case, the first indication information is no longer needed to indicate whether the SSB is transmitted in the first or second half of the frame.

[0443] It should be understood that for schemes that restrict SSB transmission, as long as the purpose of restricting SSB transmission to be limited to the first half of the frame is achieved, the specific implementation method is not limited in the embodiments of this application.

[0444] In one implementation, the terminal device can determine the starting time domain position of the first control resource set based on the first duration or the first window and the index of the first SSB.

[0445] Specifically, the terminal device can determine the transmission duration of the first SSB based on the first duration or the first window. Optionally, the network device completely transmits the first SSB within this duration. Optionally, the terminal device receives the first SSB within this duration, and then, when determining the first control resource set, the time domain position of the first control resource set is after this duration, that is, detection is performed after the first SSB is completely received.

[0446] It should be understood that the public search space is known and monitored by all UEs. Within this search space, UEs can detect cell-level public message scheduling. The symbol position corresponding to Type0-PDCCH CSS may conflict with the symbol position corresponding to SSB. Detection after fully receiving the first SSB can avoid position conflicts between Type0-PDCCH CSS and SSB.

[0447] It should be understood that determining the temporal location of the first control resource set based on the first duration or the first window can be interpreted as the starting temporal location of the first control resource set being after the time slot at the end of the first duration or the first window.

[0448] Optionally, the first window can be a DBTW. The starting time domain position of the first control resource set is determined based on the number of time slots in the DBTW and the index of the first SSB. Specifically, the starting time domain position of the first control resource set can be determined according to the following formula 6:

[0449]

[0450] Among them, O3*2 μ This indicates the number of time slots contained within O3ms, O3*2 μ =DBTW_slots, where DBTW_slots is a preset number of time slots used to transmit the first SSB.

[0451] The O3 value can be determined based on the DBTW, and the possible values ​​are:

[0452] The value of M can be a preset value. For example, the value of M can be found in Table 2.

[0453] It should be noted that the updated O3 value can directly replace the O value in Table 2, but for the sake of simplicity, it is not shown here.

[0454] It should be understood that the same parameters in the formula have the same meaning as in Formula 1 and Formula 2, and will not be elaborated here.

[0455] In one possible implementation, when the subcarrier spacing of the first SSB is 480kHz, DBTW_slots = 72, and O3 is 2.25ms; when the subcarrier spacing of the first SSB is 960kHz, DBTW_slots = 64, and O3 is 1ms.

[0456] Optionally, the first duration can be SSB_all, where SSB_all is the number of time slots corresponding to the complete transmission of the first SSB. The starting time domain position of the first control resource set is determined based on the number of time slots in SSB_all and the index of the first SSB. Specifically, the starting time domain position of the first control resource set can be determined according to the following formula 7:

[0457]

[0458] Among them, O4*2 μ This indicates the number of time slots contained within O4ms, O4*2 μ =SSB_all,

[0459] The O4 value can be determined based on the SSB_all, and can take the following values:

[0460] The value of M can be a preset value. For example, the value of M can be found in Table 2.

[0461] It should be noted that the updated O4 value can directly replace the O value in Table 2, but for simplicity, it is not shown here. It should be understood that the meanings of the same parameters in the formulas are the same as in Formulas 1 and 2, and will not be elaborated upon here.

[0462] In one possible implementation, when the subcarrier spacing of the first SSB is 480kHz, SSB_all = 32ms and the value of O4 is 1ms; when the subcarrier spacing of the first SSB is 960kHz, SSB_all = 32ms and the value of O4 is 0.5ms.

[0463] Optionally, the complete transmission duration of the first SSB can be determined by considering the first duration or the first window. When O is equal to O4, and the value is 0.5 or 5.5, the following table 3 can be used for 960kHz. It should be understood that each parameter in Table 3 is optional when implementing the scheme. For 960kHz, only one or several rows in the table can be used. This application does not limit this.

[0464] Table 3

[0465]

[0466] According to the above scheme, the terminal device can determine the complete transmission duration of the first SSB based on the first duration or the first window, and adjust the parameter O value according to the first duration or the first window so that the starting time domain position of CORESET#0 starts from the time slot after the complete transmission duration, thereby avoiding position conflicts between Type0-PDCCH CSS and SSB.

[0467] In one implementation, the terminal device can determine the starting time-domain position of the first control resource set based on the first information and the index of the first SSB.

[0468] Specifically, the terminal device can determine the number of time slots available for uplink data transmission and the location of the time slots based on the first information. The terminal device can adjust the values ​​of parameters O and M or adjust the formula based on the first information so that the starting time domain position of CORESET#0 avoids the time slot used for uplink data transmission.

[0469] For example, to avoid conflicts between CORESET#0 and the uplink time slot, the starting value needs to avoid the uplink time slot and consider as many consecutive downlink time slots as possible, such as... Figure 7 As shown, for 480kHz, there are 160 slots within a half-frame at 480kHz, and continuous time slots between uplinks can be used for downlink. There are 320 slots corresponding to 960kHz within a half-frame, and continuous time slots between uplinks can be used for downlinks. Therefore, the value of O can be {0, 1.25, 2.5, 3.75} in the first half of the 5ms frame, and similarly, it can be {5, 6.25, 7.5, 8.75} in the second half of the frame.

[0470] For example, when O = 2.5, L max When = 64, the corresponding Figure 7 The position corresponding to the starting slot is at 2.5ms. There are 32 consecutive downlink slots at 480kHz between the uplink slots. If 64 SSBs are transmitted and n0 avoids the uplink slot, then the value of M can be M = 1 / 2, which can be understood as 64 * (1 / 2) = 32. The search space corresponding to the SSB needs to be 32 consecutive slots, and the number of consecutive downlink slots at 480kHz in this configuration is 32, which just meets the requirement.

[0471] For example, if there are 64 consecutive downlink slots at 960kHz between uplink slots, and if all 64 SSBs are transmitted and n0 avoids the uplink slot, then the value of M can be M = 1 / 2 or M = 1.

[0472] For example, in an unlicensed frequency band scenario, with a subcarrier spacing of 480kHz, considering the impact of LBT failure on SSBs, a maximum of 128 SSBs can be configured. max =128. If 64 SSBs are sent in the first consecutive downlink slot and then in the second consecutive downlink slot, the corresponding SSB_indexes are 0-63 and 64-127, respectively. Taking SSB_index = 74 as an example, if M = 1 / 2, then n0 = (0 + 74 * 1 / 2) mod 320 = 36, which falls in the uplink slot; if M = 1, then n0 = (0 + 74 * 1) mod 320 = 74, which falls in the uplink slot.

[0473] Therefore, updating the value of M cannot fully meet the requirements.

[0474] Optionally, if n0 falls within the uplink time slot, the formula can be directly adjusted by adding an offset to n0 to avoid the uplink time slot, thus more flexibly avoiding uplink slot conflicts.

[0475] The starting time domain location can be determined as follows:

[0476]

[0477] Wherein, n1 represents the initial start time-domain position of the first control resource set.

[0478] When n1 is not within the time slot range available for uplink data transmission, n0 = n1.

[0479] When n1 is within the time slot range available for uplink data transmission

[0480]

[0481] Where n0 represents the starting time-domain position of the first control resource set. This indicates the number of time slots available for transmitting uplink data.

[0482] The values ​​of O and M can be preset.

[0483] For example, the values ​​of O and M can be found in Table 2.

[0484] It should be understood that the meanings of the same parameters are the same as those in Formula 1 and Formula 2, and will not be repeated here.

[0485] In one possible implementation, when the subcarrier spacing of the first SSB is 480kHz, DBTW_slots = 72, and O3 is 2.25ms. However, if uplink time slots are avoided, O3 is 2.5ms. When the subcarrier spacing of the first SSB is 960kHz, DBTW_slots = 64, and O3 is 1ms. However, if uplink time slots are avoided, O3 is 1.25ms.

[0486] In one possible implementation, when the subcarrier spacing of the first SSB is 480kHz, SSB_all = 32ms and the value of O4 is 1ms. However, if considering avoiding uplink time slots, the value of O4 is 1.25ms. When the subcarrier spacing of the first SSB is 960kHz, when SSB_all = 32ms, the value of O4 is 0.5ms. Since there is no uplink time slot at 0.5ms for 960kHz, the value of O4 is 0.5ms.

[0487] According to the above scheme, the terminal device can determine the position of the uplink time slot based on the first information. When the time domain position of the first SSB's CORESET#0 falls into the uplink time slot, the formula is further adjusted based on the first information. The adjusted formula further determines the time domain position of the first SSB's CORESET#0, so that the starting time domain position of the first SSB's CORESET#0 avoids the uplink time slot, thus avoiding the extension of detection time caused by the collision.

[0488] In one implementation, the terminal device can determine the starting time domain position of the first control resource set based on the first information, the first duration or the first window, the index of the first information and the first SSB.

[0489] Specifically, when determining the starting time domain position of the first control resource set, the terminal device fully considers the following three conditions: the time domain position of the first SSB is in the first half frame or the second half frame; the starting time domain position must be after the first SSB is sent; and it is also necessary to avoid uplink time slots.

[0490] It should be understood that the starting time-domain position of the first set of control resources that meets the above three conditions can achieve relatively good detection performance.

[0491] Alternatively, the terminal device can adjust the values ​​of parameters O and M based on the first instruction information, the first duration or the first window, and the first information.

[0492] For example, the first indication information can be half-frame bits, and based on the half-frame bits, the parameter O and M values ​​that meet the requirements of the first duration or the first window and avoid the uplink time slot are determined.

[0493] Specifically, when the subcarrier spacing of the first SSB is 120kHz, the values ​​of O and M can be taken as shown in Table 4 below.

[0494] Table 4

[0495]

[0496] It should be understood that each parameter in Table 4 above is optional when implementing the solution. For 120kHz, only one or several rows of Table 4 may be used. This application embodiment does not limit this.

[0497] Specifically, when the subcarrier spacing of the first SSB is greater than 120kHz, the values ​​of O and M can be as shown in Table 5 below.

[0498] Table 5

[0499]

[0500]

[0501] It should be understood that each parameter in Table 5 above is optional when implementing the scheme. For 480kHz or 960kHz, only one or several rows of Table 5 can be used. This application embodiment does not limit this.

[0502] Optionally, the subcarrier spacing of the first SSB is 480 kHz or 960 kHz.

[0503] Optionally, considering access latency, the value of O=3.75ms can be removed. O=0ms corresponds to detection within the same slot, O=0.5ms corresponds to detection after all SSBs have transmitted at 960kHz, O=1.25ms corresponds to the DBTW window at 960kHz and avoiding the UL slot, and O=2.5ms corresponds to the DBTW window at 480kHz and avoiding the UL slot. This yields the following Table 6:

[0504] Table 6

[0505]

[0506] It should be understood that each parameter in Table 6 above is optional when implementing the scheme. For 480kHz or 960kHz, only one or several rows of Table 6 may be used. This application does not limit this.

[0507] In one optional approach, the terminal device adjusts Formula 1 according to the first instruction information to obtain Formula 8. Based on Formula 8, it determines the O and M values ​​that satisfy the requirements of the first duration or the first window and avoid uplink time slots. At this time, the starting time domain position of the first control resource set is determined according to the following Formula 9.

[0508]

[0509] It's easy to understand that adding a half-frame time slot offset to Equation 1 can avoid the problem of correlation between the first and second half frames. The parameter definitions are the same as in Equations 1 and 2, and will not be repeated here.

[0510] Specifically, when the subcarrier spacing of the first SSB is 120kHz, the values ​​of O and M can be taken as shown in Table 7 below.

[0511] Table 7

[0512]

[0513] It should be understood that each parameter in Table 7 above is optional when implementing the scheme. For 120kHz, only one or several rows of Table 7 may be used. This application does not limit this.

[0514] Specifically, when the subcarrier spacing of the first SSB is greater than 120kHz, the values ​​of O and M can be as shown in Table 8 below.

[0515] Table 8

[0516]

[0517]

[0518] It should be understood that each parameter in Table 8 above is optional when implementing the scheme. For 120kHz, only one or several rows of Table 8 may be used. This application does not limit this.

[0519] Optionally, considering access latency, the value of O=3.75ms can be removed. O=0 corresponds to detection in the same slot, O=0.5ms corresponds to detection after all SSBs have been transmitted at 960kHz, O=1.25ms corresponds to the DBTW window at 960kHz and avoiding the UL slot, and O=2.5ms corresponds to the DBTW window at 480kHz and avoiding the UL slot. This can be obtained from Table 9 below.

[0520] Table 9

[0521]

[0522] It should be understood that each parameter in Table 9 above is optional when implementing the scheme. For 480kHz or 960kHz, only one or several rows of Table 9 may be used. This application does not limit this.

[0523] According to the above technical solution, the terminal device combines at least one of the first indication information, the first duration or the first window, the first information and the first delay, and the index of the first SSB to determine the starting time domain position of the first control resource set, so that the starting position of the first control resource set can meet the subcarrier spacing requirements of the high frequency band.

[0524] In one implementation, the terminal device can determine the starting time domain position of the first control resource set based on the first instruction information, the first duration or the first window, the first relationship, and the index of the first SSB.

[0525] In one possible implementation, the initial temporal location of the first set of control resources satisfies the following condition:

[0526]

[0527] The value of O can be determined based on the first indication information, the first duration or the first window, and the first relationship, where the first relationship is the ratio between the subcarrier spacing of the first SSB and 120kHz. The updated value of O can replace the value of O in Table 2, which is not shown here for simplicity.

[0528] Specifically, the terminal device can distinguish between the first half-frame and the second half-frame based on the first indication information, thereby avoiding the problem of the SSB of the second half-frame being associated with the first half-frame; furthermore, the first duration or the first window indicates that the first SSB is completely transmitted or is completely transmitted within a predetermined duration, so that SSB detection can be performed after transmission is complete, avoiding conflicts between the search space and SSB; based on the first indication information and the first duration or the first window, the O value of the first SSB is scaled according to the first relationship to determine the O value and M value of the subcarrier spacing that conform to the first SSB.

[0529] It should be noted that in this embodiment, the 120kHz M / O table of FR-1 can be used as a basis to design the 120kHz, 480kHz and 960kHz of FR2-2, which has low complexity and good compatibility.

[0530] Figure 8 This diagram illustrates the time-domain location of the time-division multiplexed SSB / CORESET#0 within a single system frame. It's easy to understand that the 0 value determines the offset of the starting position of CORESET#0 associated with the SSB at index 0. For example... Figure 8 As shown, in the existing protocol, the value of O is {0, 2.5, 5, 7.5}. Specifically, in the first half-frame of the SSB, the value of O is {0, 2.5, 5}. Further, to satisfy the UE's requirement to detect the first SSB after the first duration or first window, the value of O can be {2.5, 5}. This allows the UE to monitor the associated Type0-PDCCH CSS (the common search space of Type0 PDCCH) after transmitting the SSB. The SSB is transmitted during the first duration or first window; for example, it can be transmitted within the SSB burst set (DBTW window). That is, the UE monitors the associated Type0-PDCCH CSS after the entire associated SSB burst set (DBTW window). It can be understood that 2.5 and 5 correspond to SSBs with subcarrier spacing of 240kHz and 120kHz, respectively. Accordingly, for the SSB in the second half of the frame, the value of O is {0, 5, 7.5}. Furthermore, after the search window is shifted to the entire SSB burst set, the value of O is again {0, 7.5}. Therefore, it's easy to understand that for 120kHz, O = {0, 5}. When O = 0, n0 can start detection from the beginning of the SSB; when O = 5, detection occurs after the DBTW window and after avoiding the uplink time slot. Therefore, for 120kHz, O = {0, 5} already considers the 120kHz DBTW window or the issue of all SSBs being transmitted and avoiding the uplink time slot.

[0531] Furthermore, for SSBs at 480kHz and 960kHz, scaling can be performed according to the first relationship to obtain the O and M values ​​corresponding to 120kHz.

[0532] Optionally, the O value corresponding to 120kHz is denoted as O. new1 Value, the O new1 The value is determined by the following formula 10:

[0533]

[0534] Here, scale_factor represents the scaling parameter, which is a proportional relationship determined based on the first relationship.

[0535] For example, when the subcarrier spacing of the first SSB is 120kHz, the scaling ratio to 120kHz is determined to be 1 according to the first relationship, that is, the scaling parameter is 1. Then, the scaling parameter can be expressed as:

[0536] scale_factor=2 μ-3 μ = {3} for {120kHz}

[0537] For example, when the DBTW window is turned off, it can be understood that in the licensed frequency band, when the LBT is turned off, the L of the first SSB... max =64. At this point, when the subcarrier spacing of the first SSB is 480kHz, the scaling parameter is 1 / 4; when the subcarrier spacing of the first SSB is 960kHz, the scaling parameter is 1 / 8. Therefore, the scaling parameter can be expressed as:

[0538] scale_factor=2 μ-3 ,if DBTW off;μ={5,6}for{480kHz,960kHz}

[0539] For example, when the DBTW window is open, it can be understood as the LBT being open in an unlicensed frequency band, and the L of the first SSB... max =128. At this point, when the subcarrier spacing of the first SSB is 480kHz, the scaling parameter is 1 / 2; when the subcarrier spacing of the first SSB is 960kHz, the scaling parameter is 1 / 4. Therefore, the scaling parameter can be expressed as:

[0540] scale_factor=2 μ-4 ,if DBTW on;μ={5,6}for{480kHz,960kHz}

[0541] In summary, the O value for scaling based on the first relation can be expressed as:

[0542]

[0543] Optionally, in this embodiment, the first indication information can be used to distinguish SSB information with the same SSB index in different half-frames, using O new2 The O value indicates the value used to distinguish between the first half-frame and the second half-frame containing the SSB, based on the first indication information. new2 The formula is shown in Formula 11 below:

[0544]

[0545] That is, the value of O in Formula 1 can be equal to O. new2 value.

[0546] Optional, O new2 The formula is shown in Formula 12 below:

[0547]

[0548] In one possible implementation, the terminal device can determine the starting time domain position of the first control resource set based on the first instruction information, the first duration or the first window, the first relationship, and the index of the first SSB.

[0549] As can be seen from the above analysis, adjusting the value of O in Formula 1 yields Formula 13, and the starting time domain position can be determined according to Formula 13 as follows:

[0550]

[0551] Alternatively, Formula 13 can also be expressed as Formula 14:

[0552]

[0553] It should be noted that, in this embodiment of the application, for the first SSB with a subcarrier spacing of 120kHz, it is necessary to consider whether the configuration of the first symbol {0,7} of the Type0-PDCCH CSS will cause a conflict between the SSB and the Type0-PDCCH CSS.

[0554] Specifically, Figure 9This diagram illustrates a time-domain representation of an SSB and Type0-PDCCH CSS in symbol granularity according to an embodiment of this application. When using the configuration of index = 1 and 5 in Table 13-12 of Chapter 13 of TS 38-213, the parameter values ​​are O = {0, 5}, M = 1 / 2, and First symbol index = {0 if i is even, 7 if i is odd}. As can be seen from the diagram, when the starting time slot n0 of CORSERT 0 associated with the SSB falls within the same half-frame as the time slot containing SSB index i, the configuration of the first symbol {0, 7} of the Type0-PDCCH CSS will cause a conflict between SSB#0 and Type0-PDCCH CSS's CSS0#1. Therefore, the UE cannot detect the SSB and its corresponding Type0-PDCCH CSS, resulting in reduced detection efficiency of the SSB and its corresponding Type0-PDCCH CSS, thus affecting the UE access process.

[0555] In summary, for slot n0 and SSB of CORESET#0 within the same half-frame, the configuration of First symbol index = {0 if i is even, 7 if i is odd} may not be usable. For example, when 0 is 0, the first symbol in the M / O table configuration for 120kHz cannot be {0, 7}, and can only be... The configuration is as follows. However, when O=5ms, since the detection time has already shifted by half a frame, collisions are avoided, so the option {0,7} can also be configured when O=5ms.

[0556] Specifically, in this embodiment, for the first SSB with subcarrier spacing of 480kHz and 960kHz, the symbol index of the 480kHz / 960kHz SSB in FR2-2 within a time slot can be {2,9}. Two SSBs can be placed in one slot, and symbols {0,1} and {7,8} can be used to place Type0-PDCCH-CSS. Therefore, the symbol position {2,9} of the SSB pattern does not conflict with the symbol configuration {0,7} of Type0-PDCCH-CSS and can be used.

[0557] For example, for formulas 13 and 14, when the subcarrier spacing of the first SSB is 120kHz, the values ​​of O and M can be as shown in Table 10 below. It should be understood that in the specific implementation of the scheme, each parameter in Table 10 below is optional, and for 120kHz, only one or several rows in Table 10 can be used. This application does not limit this.

[0558] Table 10

[0559]

[0560] For example, when the subcarrier spacing of the first SSB is 480kHz or 960kHz, the values ​​of O and M can be as shown in Table 11 below.

[0561] Table 11

Furthermore, the units in the communication device 1200 and the other operations and / or functions described above are respectively for implementing... Figure 2 The corresponding process in method 200.

Furthermore, embodiments related to these M / O tables and their beneficial effects can also be incorporated into this embodiment. For brevity, please refer to the description of the foregoing method embodiments; further details will not be repeated here.

[0635] In one possible implementation, after the communication device 1200 used as the terminal device side searches for the SSB, it parses the PBCH of the SSB to obtain the MIB information, and obtains the time domain location parameters of the first control resource set CORESET#0 based on the MIB information.

[0636] In one possible implementation, this configuration information can also be carried in other signaling.
