Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, specifically to a communication method, a communication device, and a computer-readable storage medium. Background Technology
[0002] The synchronization signal and physical downlink broadcast channel block (SSB) consists of primary synchronization signals (PSS), secondary synchronization signals (SSS), and the physical downlink broadcast channel (PBCH). Typically, a cell can periodically broadcast the SSB.
[0003] In wireless communication, to meet requirements such as network energy conservation, on-demand SSB (Service Serving Message) transmission is proposed. For example, in carrier aggregation (CA) scenarios, secondary cells (SCells) do not broadcast SSBs periodically; instead, they broadcast SSBs based on network requests or terminal device requests. SSBs broadcast by secondary cells based on requests can be called on-demand SSBs (OD-SSBs). That is, on-demand SSBs are transmitted only after being triggered.
[0004] For periodically broadcast SSBs, network devices can send SSB-based measurement timing configuration (SMTC) information to terminal devices, allowing the terminal devices to measure the SSB based on this configuration information. How terminal devices can measure on-demand SSBs is currently a hot research topic. Summary of the Invention
[0005] This application provides a communication method, a communication device, and a computer-readable storage medium, which enables terminal devices to measure SSB on demand, thereby improving communication performance.
[0006] In a first aspect, embodiments of this application provide a communication method applicable to a terminal device. That is, the method can be executed by the terminal device or by a device compatible with the terminal device, such as a processor or chip. The method may include: receiving a first signaling from a network device, the first signaling indicating the activation or deactivation of configuration information of a reference SMTC; wherein the configuration information of the reference SMTC is used to measure a first SSB, the first SSB being either an on-demand SSB or an adaptive SSB; in response to the first signaling indicating the activation of the reference SMTC configuration information, measuring the first SSB based on the configuration information of the first SMTC, the configuration information of the reference SMTC including the configuration information of the first SMTC; and in response to the first signaling indicating the deactivation of the reference SMTC configuration information, measuring the first SSB based on the configuration information of a second SMTC.
[0007] The configuration information of the second SMTC is used to measure the second SSB, which is a periodic SSB. The configuration information of the second SMTC is not the same as the configuration information of the reference SMTC, while the configuration information of the first SMTC is. The configuration information of the reference SMTC is used to provide a general description of the SMTC configuration information for the first SSB. There may be one or more sets of configuration information for the SMTC for the first SSB, and the configuration information of the first SMTC is one of them. The configuration information of the SMTC for the first SSB is only used to measure the first SSB and cannot be used to measure the second SSB. The configuration information of the second SMTC can be used to measure the second SSB, and in some cases, it can also be used to measure the first SSB. For example, when the first signaling indicates deactivation, the configuration information of the second SMTC can also be used to measure the first SSB. The configuration information of the reference SMTC can also be understood as the configuration information of the SMTC other than the configuration information of the second SMTC, or additional SMTC configuration information, etc.
[0008] The first signaling can be a medium access control-control element (MAC-CE).
[0009] As can be seen, the configuration information of the SMTC for the first SSB is activated or deactivated by the first signaling instruction, so that the terminal device can measure the first SSB based on the configuration information of the SMTC for the first SSB, or based on the configuration information of the second SMTC, thereby enabling the terminal device to measure the SSB on demand or adaptively.
[0010] When the first signaling indicates activation, the terminal device can use the configuration information of the first SMTC to measure the first SSB; when the first signaling indicates deactivation, the terminal device can use the configuration information of the second SMTC to measure the first SSB, so that the SMTC for measuring the first SSB can be different each time the first SSB is activated, thereby improving communication performance.
[0011] In one possible implementation, the method further includes receiving a first RRC signaling from a network device, the first RRC signaling including configuration information of a first SMTC. That is, the configuration information of the first SMTC is communicated to the terminal device via the first RRC signaling, so that the terminal device can measure the first SSB based on the configuration information of the first SMTC when the first signaling indicates activation.
[0012] In one possible implementation, the measurement object containing the configuration information of the first SMTC is different from the measurement object containing the configuration information of the second SMTC, thereby distinguishing the configuration information of the SMTCs through the measurement object. That is, a measurement object is configured for the first SSB, which includes the configuration information of the first SMTC; a measurement object is configured for the second SSB, which includes the configuration information of the second SMTC. The content included in the different measurement objects can be different, for example, different SSB frequencies, different SSB subcarrier spacing (SCS), etc. In other words, in this method, the frequency of the first SSB may be different from the frequency of the second SSB, and the subcarrier spacing of the first SSB may be different from the subcarrier spacing of the second SSB, etc.
[0013] In one possible implementation, the first RRC signaling also includes the configuration information of the second SMTC. In other words, the measurement object containing the configuration information of the first SMTC is the same as the measurement object containing the configuration information of the second SMTC. Including the configuration information of both the first and second SMTCs within a single measurement object saves signaling overhead.
[0014] In one possible implementation, when the first RRC signaling includes configuration information for both the first and second SMTCs, the configuration information for the first SMTC indicates one or more of the following: a cell identifier list, the window duration of the first SMTC, the window period of the first SMTC, the window offset of the first SMTC, and the SSBs to be measured. The cell identifier list indicates the cells to which the configuration information of the first SMTC can be applied; in other words, for the first SSBs of these cells, the terminal device can measure the first SSB within the window of the first SMTC. The SSBs to be measured indicate which SSBs need to be measured, which may include the first SSB.
[0015] In one possible implementation, where the first RRC signaling includes configuration information of the first SMTC and the second SMTC, the first signaling is also used to indicate the first SSB transmission period, so that the terminal device measures the first SSB based on the configuration information of the first SMTC and the first SSB transmission period.
[0016] Optionally, in this approach, the method further includes: receiving a list of SSB transmission cycles for a first SSB, the list comprising multiple SSB transmission cycles, with the first SSB transmission cycle being one of these multiple SSB transmission cycles. The list of SSB transmission cycles corresponds to the configuration information of a first SMTC. In other words, the configuration information of the first SMTC applies to each SSB transmission cycle in the list of SSB transmission cycles. The terminal device can measure the first SSB for different SSB transmission cycles based on the configuration information of the first SMTC.
[0017] In one possible implementation, the first RRC signaling includes a configuration information list and the configuration information of the second SMTC. The configuration information list includes configuration information for multiple SMTCs, and the configuration information for these multiple SMTCs includes the configuration information of the first SMTC. The configuration information for all multiple SMTCs is specific to the first SSB. The configuration information for the multiple SMTCs corresponds to multiple SSB transmission cycles; one SMTC's configuration information corresponds to one SSB transmission cycle and is used to measure the first SSB within that SSB transmission cycle. In other words, the configuration information for one SMTC is used to measure the first SSB based on one SSB transmission cycle.
[0018] In one possible implementation, when the first RRC signaling includes a configuration information list and the configuration information of the second SMTC, the first signaling is also used to indicate the first SSB transmission period, so that the terminal device can determine the configuration information of the SMTC corresponding to the first SSB transmission period based on the above correspondence, assuming it is the configuration information of the first SMTC, and measure the first SSB based on the configuration information of the first SMTC and the first SSB transmission period.
[0019] Optionally, in this manner, the method further includes: receiving an SSB transmission list of a first SSB, the SSB transmission period list including multiple SSB transmission periods, the first SSB transmission period being one of the multiple SSB transmission periods.
[0020] In one possible implementation, the first signaling is also used to indicate that the first SSB is activated, so that the terminal device can measure the first SSB based on whether the configuration information of the reference SMTC is activated, using the configuration information of the first SMTC or the configuration information of the second SMTC.
[0021] Secondly, embodiments of this application provide a communication method that can be applied to a network device. That is, the method can be executed by the network device or by a device compatible with the network device, such as a processor or chip. The method may include: sending a first signaling message to a terminal device, the first signaling message being used to indicate the activation or deactivation of configuration information of a reference SMTC; wherein the configuration information of the reference SMTC is used to measure a first SSB, the first SSB being either an on-demand SSB or an adaptive SSB.
[0022] As can be seen, the network device instructs the terminal device to activate or deactivate via the first signaling, referring to the configuration information of the SMTC, so that the terminal device can measure the first SSB based on the configuration information of the reference SMTC or based on the configuration information of the second SMTC, thereby enabling the terminal device to measure the SSB on demand or adaptively.
[0023] In one possible implementation, the method further includes: sending a first RRC signaling message to the terminal device, the first RRC signaling message including configuration information of the first SMTC; and referencing the configuration information of the SMTC including the configuration information of the first SMTC.
[0024] In one possible implementation, the measurement object containing the configuration information of the first SMTC is different from the measurement object containing the configuration information of the second SMTC; the configuration information of the second SMTC is used to measure the second SSB, which is a periodic SSB.
[0025] In one possible implementation, the first RRC signaling also includes configuration information for the second SMTC, which is used to measure the second SSB, which is a periodic SSB.
[0026] In one possible implementation, the configuration information of the first SMTC indicates one or more of the following: a cell identifier list, the window duration of the first SMTC, the window period of the first SMTC, the window offset of the first SMTC, and the SSB to be measured; wherein the SSB to be measured includes the first SSB.
[0027] In one possible implementation, the first RRC signaling includes a configuration information list, which includes configuration information of multiple SMTCs, and the configuration information of the multiple SMTCs includes the configuration information of the first SMTC.
[0028] In one possible implementation, the first RRC signaling also includes the correspondence between the configuration information of multiple SMTCs and multiple SSB transmission cycles, wherein the configuration information of one SMTC is used to measure the first SSB based on one SSB transmission cycle.
[0029] In one possible implementation, the first signaling is also used to indicate the first SSB transmission cycle.
[0030] In one possible implementation, the method further includes: sending a list of SSB transmission cycles of the first SSB to the terminal device, the list of SSB transmission cycles including the first SSB transmission cycle.
[0031] In one possible implementation, the configuration information of the first SMTC is the configuration information of the SMTC corresponding to the first SSB transmission cycle.
[0032] In one possible implementation, the first signaling is also used to indicate that the first SSB is activated, so that the terminal device can measure the first SSB based on whether the configuration information of the reference SMTC is activated, using the configuration information of the first SMTC or the configuration information of the second SMTC.

[0048] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0049] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.
[0050] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0051] In this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.
[0052] In this application, "sending information to... (e.g., a terminal device)" can be understood as the destination of the information being the terminal device. This can include sending information directly or indirectly to the terminal device. "Receiving information from... (e.g., a terminal device)" or "receiving information from... (e.g., a terminal device)" can be understood as the source of the information being the terminal device, and can include receiving information directly or indirectly from the terminal device. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be interpreted similarly, and will not be elaborated further here.
[0053] In the description of this application, "instruction" can include direct and indirect instructions, as well as explicit and implicit instructions. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed. For example, the information to be instructed can be directly indicated, such as by indicating the information to be instructed itself or its index. Alternatively, the information to be instructed can be indirectly indicated by indicating other information, where there is a relationship between the indicated other information and the information to be instructed. Another example is that only a part of the information to be indicated can be indicated, while the other parts are known or pre-agreed upon. Furthermore, the instruction of specific information can be achieved by using a pre-agreed (such as an agreement) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.
[0054] To better understand the embodiments of this application, the system architecture involved in the embodiments of this application will be described first below:
[0055] This application's embodiments can be applied to long-term evolution (LTE) systems, 5th generation mobile communication (5G) systems, 6th generation mobile communication (6G) systems, and other communication systems evolving after 5G, as well as satellite communication and short-range wireless communication systems. The wireless communication systems mentioned in this application's embodiments include, but are not limited to: the three major application scenarios of 5G / 6G mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC), long-range (LoRa) systems, or vehicle-to-everything (V2X) systems. The wireless communication system may include one or more network devices and one or more terminal devices.
[0056] The following is based on Figure 1 The system architecture shown is illustrated as an example. Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one network device (such as...). Figure 1 110a and 110b (collectively referred to as 110) and at least one terminal device (such as Figure 1 RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the image). Terminal device 120 is connected to network device 110 wirelessly. Network device 110 is connected to core network 200 wirelessly or via wired connection. The core network device in core network 200 and network device 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.
[0057] It should be noted that RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or evolutionary systems beyond 5G (e.g., 6G mobile communication systems). RAN 100 can also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), etc. RAN 100 can also be a communication system that integrates two or more of the above systems. It should be stated that... Figure 1 The number of network devices and terminal devices shown is merely illustrative and should not be considered a specific limitation of this application. The terminal devices and network devices involved in the system architecture will be described in detail below.
[0058] I. Terminal Equipment
[0059] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device used to provide voice or data connectivity to users, and can also be an Internet of Things (IoT) device. For example, terminal equipment includes handheld devices with wireless connectivity, in-vehicle devices, etc. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices (such as smartwatches, smart bracelets, pedometers, etc.), in-vehicle equipment (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, smart point-of-sale (POS) machines, customer-premises equipment (CPE), wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in autonomous driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, and flying equipment (such as intelligent robots, hot air balloons, drones, airplanes), etc. Terminal devices can also be other devices with terminal functions; for example, a terminal device can also be a device that performs terminal functions in D2D communication.
[0060] The embodiments of this application do not limit the form of the terminal device. The device used to implement the functions of the terminal device can be the terminal device itself, or it can be a device that supports the terminal device in implementing the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of chips, or it can include chips and other discrete components.
[0061] II. Network Equipment
[0062] Network devices are nodes in a radio access network (RAN), and can also be called RAN nodes (or devices). Network devices help terminal devices achieve wireless access. Multiple network devices 110 in a communication system can be nodes of the same type or different types. In some scenarios, the roles of network devices 110 and terminal devices 120 are relative, for example... Figure 1 Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminal devices 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for network element 110a, network element 120i is a terminal device. Network device 110 and terminal device 120 are sometimes referred to as communication devices, for example... Figure 1 Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal equipment functions.
[0063] In one possible scenario, network equipment can be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next-generation NodeB (gNB), a next-generation base station in a 6th-generation (6G) mobile communication system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, or network equipment in a mobile switching center non-terrestrial network (NTN) communication system, meaning it can be deployed on high-altitude platforms or satellites. Network equipment can also be a macro base station (such as...). Figure 1 110a), micro base stations or indoor stations (such as Figure 1In CRAN scenarios, network devices can be 110b), relay nodes or donor nodes, or wireless controllers. Network devices can also function as base stations in device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, drone communication, and machine-to-machine (M2M) communication. Optionally, network devices can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in vehicle-to-everything (V2X) technology, the network device can be a roadside unit (RSU).
[0064] All or part of the functions of the network device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform). The network device in this application can also be a logical node, logical module, or software capable of implementing all or part of the functions of a network device.
[0065] In another possible scenario, multiple network devices collaborate to assist terminals in achieving wireless access, with each network device performing a portion of the base station's functions. For example, network devices can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). It is understood that network devices can be CU nodes, DU nodes, or devices comprising both CU and DU nodes. Furthermore, CUs can be classified as network devices in the access network (RAN) or the core network (CN), without limitation.
[0066] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.
[0067] In this embodiment, the form of the network device is not limited. The device used to implement the function of the network device can be the network device itself, or it can be a device that supports the network device in implementing the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device.
[0068] To facilitate understanding of the content of this solution, some terms used in the embodiments of this application will be explained below, so that those skilled in the art can understand them. This part is only for the purpose of understanding and should not be regarded as a specific limitation of this application.
[0069] 1. SSB
[0070] An SSB consists of a PSS, an SSS, and a PBCH. In the time domain, one SSB occupies four orthogonal frequency-division multiplexing (OFDM) symbols; in the frequency domain, one SSB occupies 20 consecutive physical resource blocks (PRBs). The specific symbols and PRBs occupied by the PSS, SSS, and PBCH are not limited in this embodiment. For ease of description, OFDM symbols can be simply referred to as symbols. In the time domain, the number and position of SSBs within a half-frame (i.e., 5ms) are determined according to the subcarrier spacing and frequency band; multiple SSBs within a half-frame form an SS burst set.
[0071] The number of SSBs varies across different frequency bands. For example, for Sub3G, Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD) below 2.4G define a maximum of 4 SSBs, while TDD above 2.4G defines a maximum of 8 SSBs; for Sub3G to Sub6G, a maximum of 8 SSBs are defined; and for Sub6G and above, a maximum of 64 SSBs are defined.
[0072] This application's embodiments involve three types of SSBs: on-demand SSB, adaptive SSB, and periodic SSB.
[0073] (1) Periodic SSB
[0074] Periodic SSBs refer to SSBs that are periodically transmitted by a cell or base station. Typically, cells or base stations broadcast SSBs periodically. The transmission period of a periodic SSB can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. The specific transmission period can be configured by the base station via RRC signaling.
[0075] In the embodiments of this application, periodic SSB refers to an SSB that is continuously sent according to a fixed transmission period, such as continuously sending an SSB with a transmission period of 20ms.
[0076] For periodic SSBs, the configuration information may include one or more of the following:
[0077] The SSB frequency point is used to indicate the frequency point of a periodic SSB, that is, the center frequency point of the periodic SSB in the frequency domain, which determines the position of the SSB in the spectrum.
[0078] Subcarrier spacing, used to indicate the subcarrier spacing of a periodic SSB, determines the bandwidth of the SSB in the frequency domain and the symbol length in the time domain. Examples of subcarrier spacing include 15 kHz and 30 kHz.
[0079] Transmission period, used to indicate the transmission period of a periodic SSB.
[0080] SSB position indication information is used to indicate the position information of the SSB within a period, such as the specific position of the SSB in the time slot, the number of symbols occupied, and the position of the occupied symbols.
[0081] Transmit power indication information is used to indicate the power level of the base station or cell transmitting SSB.
[0082] This information is used for illustrative purposes and does not constitute a limitation on the embodiments of this application; it may actually include more information.
[0083] (2) On-demand SSB
[0084] On-demand SSB refers to SSBs that are sent on demand. In wireless communication, on-demand SSBs are proposed to meet the needs of network energy saving. For example, in a CA (Communication as a Secondary Cell) scenario, secondary cells do not periodically broadcast SSBs, but rather broadcast SSBs based on network requests or requests from terminal devices.
[0085] For example, on-demand SSB delivery can be found in [reference needed]. Figure 2A and Figure 2B The example diagram is shown. Figure 2A and Figure 2B In the above, Scenario #2 represents the process from when the secondary cell is configured to when the secondary cell activation command is received; Scenario #3A represents the process from when the secondary cell activation command is received to when the secondary cell activation is completed; and Scenario #3B represents the process after the secondary cell activation is completed. Figure 2A and Figure 2B In scenario #2, network requests or terminal device requests can trigger the sending of on-demand SSBs, i.e., on-demand SSB triggering (not shown in the figure).
[0086] exist Figure 2A In this system, there is no always-on SSB within the cell. Once an on-demand SSB is triggered, it can be transmitted periodically. An always-on SSB can be understood as a periodic SSB. After an on-demand SSB is triggered, it can be transmitted periodically.
[0087] exist Figure 2B Within an SSB burst or window, SSBs are transmitted periodically, meaning there are periodic SSBs. Figure 2B In this context, SSB stands for Periodic SSB. When on-demand SSB transmission is required, additional on-demand SSBs can be transmitted within an SSB burst or window. For periodic SSBs, longer transmission periods can reduce energy consumption but impact performance, such as causing synchronization or automatic gain control delays. Performance can be improved by transmitting additional on-demand SSBs within an SSB burst or window.
[0088] Figure 2A and Figure 2B In this context, on-demand SSB triggering is issued via MAC-CE. MAC-CE can include an on-demand SSB activation indication for a cell, indicating whether the on-demand SSB for that cell is activated or not. An activated on-demand SSB means that the cell has been triggered to transmit on-demand SSBs; an inactive on-demand SSB means that the cell has not been triggered to transmit on-demand SSBs. MAC-CE can include on-demand SSB activation indications for 7 or 31 cells, indicating whether the on-demand SSB for each cell is activated.
[0089] Optionally, MAC-CE may also include a transmission period indicator for on-demand SSBs. One implementation is that the on-demand SSB transmission period indicator specifies the transmission period value for the on-demand SSB, for example, indicating a transmission period of 10ms. The indicated transmission period value may apply to all activated on-demand SSBs, or it may indicate different transmission period values for different cells. Another implementation is that RRC signaling configures multiple transmission periods for the on-demand SSB, and the on-demand SSB transmission period indicator is used to indicate the transmission period index. That is, the on-demand SSB transmission period indicator indicates one of multiple transmission periods. The indicated transmission period index may apply to all activated on-demand SSBs, or it may indicate different transmission period indices for different cells.
[0090] Typically, on-demand SSBs are activated so that terminal devices can measure them to obtain cell measurement results. Because on-demand SSBs are usually sent over a period of time rather than continuously, the transmission period of on-demand SSBs is shorter than that of continuously sent SSBs; that is, the transmission period of on-demand SSBs is shorter than that of periodic SSBs.
[0091] For on-demand SSBs, the configuration information may include one or more of the following:
[0092] SSB configuration identifier is used to identify a set of configuration information for an on-demand SSB.
[0093] Transmission period, used to indicate the transmission period of on-demand SSB.
[0094] The activation time of an on-demand SSB indicates the duration for which the on-demand SSB will be sent. In other words, an on-demand SSB will not send continuously, but rather within a specific timeframe; this timeframe is the activation time. For example, if the activation time is 5ms, then the on-demand SSB will be sent within those 5ms.
[0095] The number of on-demand SSB bursts indicates the number of on-demand SSB bursts sent. Each burst includes multiple SSBs. For example, if the burst duration is 5ms and the on-demand SSB transmission period is 20ms, one burst includes four SSBs: SSB#0, SSB#1, SSB#2, and SSB3. See the example below. Figure 3 The diagram illustrates the relationship between burst duration and transmission period. This example shows a 5ms burst of on-demand SSBs sent every 20ms, consisting of SSB#0, SSB#1, SSB#2, and SSB3. The burst duration is the activation time of the aforementioned on-demand SSBs.
[0096] The SSB frequency point indicates the frequency point of the on-demand SSB, that is, the center frequency point of the on-demand SSB in the frequency domain, which determines the position of the SSB in the spectrum. The frequency point of the on-demand SSB may be the same as or different from the frequency point of the periodic SSB.
[0097] The subcarrier spacing of the SSB indicates the subcarrier spacing of the on-demand SSB, which determines the bandwidth of the SSB in the frequency domain and the symbol length in the time domain. For FR1, the subcarrier spacing of the on-demand SSB is 15kHz or 30kHz; for FR2-1, the subcarrier spacing of the on-demand SSB is 120kHz or 240kHz; and for FR2-2, the subcarrier spacing of the on-demand SSB is 120kHz, 480kHz, or 960kHz.
[0098] The power signaling associated with SSB may include, for example, the average energy per resource element (EPRE) carrying auxiliary synchronization signals used by the network for SSB transmission. The unit of EPRE is dBm.
[0099] SSB burst position indication information is used to indicate the position information of a transmitted SSB. The SSB burst position indication information can indicate the time-domain position of a transmitted SSB within a half-frame containing the SSB. The SSB burst position indication information can be indicated using a bitmap, which can contain 4, 8, or 64 bits. For example, a bitmap containing 4 bits: the first bit indicates the time-domain position of SSB#0, the second bit indicates the time-domain position of SSB#1, the third bit indicates the time-domain position of SSB#2, and the fourth bit indicates the time-domain position of SSB#3.
[0100] This information is used for illustrative purposes and does not constitute a limitation on the embodiments of this application; it may actually include more information.
[0101] (3) Adaptive SSB
[0102] An adaptive SSB refers to an SSB whose transmission period can be adaptively changed. For example, an SSB is sent with a transmission period of 160ms. After the adaptive SSB is activated, it is sent with a transmission period of 80ms. After the adaptive SSB is deactivated, it is sent with a transmission period of 160ms.
[0103] Optionally, SSB adaptation being activated or deactivated can be indicated by MAC-CE. Optionally, the MAC-CE can also indicate the transmission period after adaptation is activated, such as 80ms in the example above.
[0104] For adaptive SSBs, in addition to the configuration information of periodic SSBs, the configuration information also includes adaptive period information to indicate the transmission period after the adaptation is activated, such as 80ms in the example above.
[0105] 2. SMTC
[0106] Terminal devices can measure SSBs. To reduce power consumption during measurement, 5G introduces SMTC-based SSB measurement. The terminal device measures the SSB within the SMTC window; outside the window, no measurement is required. In other words, the SMTC window is used for SSB measurement, and it represents the time window for the terminal device to measure the SSB. SMTC configuration information can include one or more of the following: period, offset, and duration. The period represents the SMTC window period, i.e., the period of the window for measuring the SSB, which can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. The offset represents the offset of the SMTC window relative to the system frame. The duration represents the length of the SMTC window, which can be 1ms, 2ms, 3ms, 4ms, or 5ms.
[0107] All three types of SSBs (i.e., periodic SSB, on-demand SSB, and adaptive SSB) are measured based on SMTC, meaning they are measured within the SMTC window. Typically, for a single SSB frequency point, all SSB measurements at that frequency point follow a single SMTC measurement set, meaning the SSB measurement is based on a single SMTC configuration information. Before the introduction of on-demand or adaptive SSBs, terminal devices measured periodic SSBs based on this configuration information. However, after the introduction of on-demand or adaptive SSBs, since the transmission period of on-demand and adaptive SSBs may be shorter than that of periodic SSBs, the SMTC configuration information used for periodic SSB measurements may not be applicable to on-demand or adaptive SSB measurements. Therefore, another set of SMTC configuration information can be used to measure on-demand or adaptive SSBs. This other set of SMTC configuration information can also be referred to as additional SMTC configuration information. For example, for periodic SSB measurements, SMTC configuration information 1 can be used for measurement; for on-demand SSB or adaptive SSB, SMTC configuration information 2 can be used for measurement, which is additional SMTC configuration information.
[0108] However, since the transmission period after each activation of an on-demand SSB or adaptive SSB may differ, the SMTC window may also differ. Therefore, additional SMTC configuration information may not be applicable to all activated on-demand or adaptive SSBs. For example, if the transmission period after activation of an on-demand SSB in cell 1 is 20ms, while that in cell 2 is 40ms, then the SMTC window duration required to measure the on-demand SSB in cell 2 must be longer than that required to measure the on-demand SSB in cell 1. Thus, the additional SMTC configuration information cannot meet all measurement requirements. Furthermore, additional SMTC configuration information is not always necessary after each activation of an on-demand or adaptive SSB.
[0109] In view of this, embodiments of this application provide a communication method, communication device, and computer-readable storage medium, which enable a terminal device to measure on-demand SSB or adaptive SSB, thereby improving communication performance. When on-demand SSB or adaptive SSB is activated, additional SMTC configuration information is activated or deactivated. When additional SMTC configuration information is activated, the terminal device can measure on-demand SSB or adaptive SSB based on the additional SMTC configuration information; when deactivated, the terminal device can measure on-demand SSB or adaptive SSB based on the traditional SMTC configuration information, that is, based on the configuration information of the SMTC that measures periodic SSBs.
[0110] The communication method provided in this application embodiment can be applied to Figure 2A or Figure 2B The on-demand SSB transmission scenario shown can also be applied to adaptive SSB transmission scenarios, as well as other on-demand SSB transmission scenarios.
[0111] The following is based on Figure 1 The system architecture shown here provides a detailed explanation of the communication method provided in the embodiments of this application.
[0112] Please see Figure 4 This is a flowchart illustrating a communication method provided in an embodiment of this application. The method may include, but is not limited to, the following steps:
[0113] 401. The network device sends a first signaling message to the terminal device. Correspondingly, the terminal device receives the first signaling message from the network device. This first signaling message is used to indicate whether to activate or deactivate the configuration information of the reference SMTC.
[0114] The first signaling instruction is MAC-CE, which is used to indicate whether to activate or deactivate the configuration information of the reference SMTC. Activating the configuration information of the reference SMTC means using the configuration information of the reference SMTC; deactivating the configuration information of the reference SMTC means not using the configuration information of the reference SMTC, but using the configuration information of another SMTC.
[0115] In one implementation, MAC-CE includes a bit whose value is used to indicate whether the configuration information of the reference SMTC is activated or deactivated.
[0116] Optionally, the MAC-CE includes an activation identifier used to indicate whether the configuration information of the reference SMTC is activated or deactivated. For example, the activation identifier is a single bit of the MAC-CE; a value of 1 indicates activation of the reference SMTC's configuration information, while a value of 0 indicates deactivation of the reference SMTC's configuration information.
[0117] Optionally, the MAC-CE includes a disable flag, which is used to indicate whether the configuration information of the reference SMTC is activated or deactivated. For example, the disable flag is a one-bit of the MAC-CE, where a value of 1 indicates that the configuration information of the reference SMTC is deactivated, and a value of 0 indicates that the configuration information of the reference SMTC is activated.
[0118] The SMTC configuration information is used to provide a general description of the SMTC configuration information for on-demand SSBs or adaptive SSBs, and may be the additional SMTC configuration information mentioned above. There may be one or more sets of additional SMTC configuration information. Whether there is one or more sets of additional SMTC configuration information can be indicated via RRC signaling.
[0119] The first signaling instruction activates additional SMTC configuration information. If there is one set of additional SMTC configuration information, the terminal device activates that set. If there are multiple sets of additional SMTC configuration information, the terminal device can activate one of them. For example, if the additional SMTC configuration information includes configuration information 1, configuration information 2, and configuration information 3, and the first signaling instruction activates the additional SMTC configuration information, the terminal device can independently determine whether to activate configuration information 1, configuration information 2, or configuration information 3. Furthermore, if the first signaling instruction deactivates the additional SMTC configuration information, the terminal device measures either on-demand SSB or adaptive SSB based on the configuration information of the SMTC used to measure periodic SSBs.
[0120] In another implementation, MAC-CE includes multiple bits, and the value of one bit is used to indicate whether the corresponding configuration information is activated or deactivated.
[0121] Optionally, if there is an additional set of SMTC configuration information, the MAC-CE may include two bits. The first bit indicates whether the configuration information for the periodic SSB's SMTC is activated or deactivated, and the second bit indicates whether the configuration information for the additional SMTC is activated or deactivated. For example, these two bits can be represented as 10, with the first bit valued at 1 indicating activation of the periodic SSB's SMTC configuration information and the second bit valued at 0 indicating deactivation of the additional SMTC configuration information. As another example, these two bits can be represented as 01, with the first bit valued at 0 indicating deactivation of the periodic SSB's SMTC configuration information and the second bit valued at 1 indicating activation of the additional SMTC configuration information.
[0122] Optionally, if there are M sets of additional SMTC configuration information, the MAC-CE may include M+1 bits. The value of the first bit is used to indicate the activation or deactivation of the SMTC configuration information for the periodic SSB, and the value of any of the remaining bits is used to indicate the activation or deactivation of the additional SMTC configuration information. Here, M is a positive integer greater than or equal to 2. Assuming M = 3, meaning the additional SMTC configuration information includes configuration information 1, configuration information 2, and configuration information 3, the MAC-CE may include four bits. Assuming the first bit is used to indicate the activation or deactivation of the SMTC configuration information for the periodic SSB, the second bit is used to indicate the activation or deactivation of configuration information 1, the third bit is used to indicate the activation or deactivation of configuration information 2, and the fourth bit is used to indicate the activation or deactivation of configuration information 3. For example, these four bits can be represented as 1000, with the first bit valued at 1, indicating the activation of the SMTC configuration information for the periodic SSB; the remaining three bits are all 0, indicating the deactivation of configuration information 1 to configuration information 3. For example, these four bits can be represented as 0100. The first bit is 0, indicating that the configuration information of the SMTC for the periodic SSB is deactivated; the second bit is 1, indicating that configuration information 1 is activated; and the remaining two bits are both 0, indicating that configuration information 1 and configuration information 2 are deactivated. That is to say, if there are multiple sets of additional SMTC configuration information, and the first signaling indicates that additional SMTC configuration information is activated, the first signaling can also indicate which configuration information is activated or deactivated.
[0123] In another implementation, MAC-CE includes a first part, which may include a single bit whose value indicates whether the configuration information of the reference SMTC is activated or deactivated. If there are multiple sets of additional SMTC configuration information, MAC-CE may also include a second part, the number of bits in which the second part includes the same number of sets of additional SMTC configuration information. If there is only one set of additional SMTC configuration information, MAC-CE does not need to include a second part.
[0124] For example, the additional SMTC configuration information includes configuration information 1, configuration information 2, and configuration information 3. MAC-CE can include four bits. Assuming configuration information 1 is activated, these four bits can represent "1|100". Here, "|" is used to separate the first and second parts. The first part has a value of "1", indicating activation of the additional SMTC configuration information; the second part has a value of "100", indicating activation of configuration information 1. As another example, these four bits can be represented as "0|000", indicating deactivation of the additional SMTC configuration information. As yet another example, these four bits can be represented as "1|010", indicating activation of configuration information 2. That is, if there are multiple sets of additional SMTC configuration information, and the first signaling indicates activation of the additional SMTC configuration information, the first signaling can also indicate which configuration information to activate or deactivate.
[0125] The above three implementation methods are for illustrative purposes only and do not constitute a limitation on the embodiments of this application.
[0126] Optionally, MAC-CE is also used to indicate that a first SSB is activated, and that the first SSB is either an on-demand SSB or an adaptive SSB, so that the terminal device can measure the first SSB based on the configuration information of a reference SMTC; or based on the configuration information of an SMTC that measures periodic SSBs. For an on-demand SSB, MAC-CE indicates whether the on-demand SSB of each of the multiple secondary cells is activated, and for an activated on-demand SSB, it also indicates whether the configuration information of the reference SMTC is activated or deactivated. For an adaptive SSB, MAC-CE indicates that SSB adaptation is activated, and also indicates whether the configuration information of the reference SMTC is activated or deactivated.
[0127] Optionally, MAC-CE is also used to indicate the first SSB transmission period, which is the transmission period of the activated first SSB. That is, MAC-CE is also used to indicate the transmission period index of the first SSB, which identifies the transmission period of the first SSB. For an on-demand SSB, the first SSB transmission period is the transmission period of the activated on-demand SSB; for an adaptive SSB, the first SSB transmission period is the transmission period after the adaptive SSB is activated. For example, if a periodic SSB sends SSBs with a transmission period of 160ms, and after the adaptive SSB is activated, it sends SSBs with a transmission period of 80ms, then the first SSB transmission period is 80ms. The first SSB transmission period can be one of a pre-configured list of multiple first SSB transmission periods. For example, a pre-configured list of first SSB transmission periods can be represented as {period #0, period #1, period #2}, where the first SSB transmission period can be period #0, period #1, or period #2. The list of first SSB transmission periods can be configured via RRC signaling.
[0128] 402a, in response to a first signaling instruction to activate the configuration information of a reference SMTC, the terminal device measures the first SSB based on the configuration information of the first SMTC. The configuration information of the reference SMTC includes the configuration information of the first SMTC.
[0129] When the first signaling instruction activates the configuration information of the reference SMTC, the terminal device measures the first SSB based on the configuration information of the first SMTC. The configuration information of the reference SMTC includes the configuration information of the first SMTC. That is, the configuration information of the first SMTC is one set of the configuration information of the reference SMTC.
[0130] In one implementation, the configuration information of the first SMTC applies to all transmission cycles of the first SSB. That is, regardless of the transmission cycle value of the first SSB indicated by the MAC-CE, the terminal device measures the first SSB based on the configuration information of the first SMTC when the first signaling indicates activation of the reference SMTC's configuration information. The configuration information of the first SMTC can be indicated via RRC signaling.
[0131] In another implementation, the configuration information of the reference SMTC includes multiple sets, with different SMTC configuration information corresponding to different transmission periods. Here, the transmission period refers to the transmission period of the first SSB. For example, the configuration information list of the reference SMTC can be represented as {Configuration Information #0, Configuration Information #1, Configuration Information #2}, and the transmission period list of the first SSB can be represented as {Period #0, Period #1, Period #2}, where Configuration Information #0 corresponds to Period #0, Configuration Information #1 corresponds to Period #1, and Configuration Information #2 corresponds to Period #2. When the MAC-CE indicates that the configuration information of the reference SMTC is activated and indicates Period #0, the terminal device measures the first SSB based on Configuration Information #0. The configuration information list of the reference SMTC can be indicated via RRC signaling.
[0132] 402b, in response to a first signaling instruction to deactivate the configuration information of the reference SMTC, the terminal device measures the first SSB based on the configuration information of the second SMTC.
[0133] When the first signaling instruction indicates that the configuration information of the reference SMTC should be deactivated, the terminal device measures the first SSB based on the configuration information of the second SMTC. The configuration information of the second SMTC is a measurement configuration for the SSB frequency point. The terminal device performs SSB measurements at this SSB frequency point, and the measurement results of the SSB or the cell can be obtained from this measurement. The configuration information of the second SMTC is used to measure the second SSB, which is a periodic SSB. The configuration information of the second SMTC is not the configuration information of the reference SMTC. That is, when the first signaling instruction indicates that the configuration information of the reference SMTC should be deactivated, the terminal device uses the configuration information of the SMTC for measuring periodic SSBs to measure the first SSB. The configuration information of the second SMTC is the configuration information for the main measurement time.
[0134] For terminal devices, if the configuration information of the first SMTC is activated, the terminal device will have two sets of SMTC configuration information (i.e., the configuration information of the first SMTC and the configuration information of the second SMTC). The following processing flow applies to these two sets of SMTC configuration information:
[0135] (1) The terminal device sets up the SMTC according to the configuration information of the second SMTC. The system frame number (SFN) and subframe of the first subframe of each SMTC are calculated by the following formula:
[0136] SFN mod T=(FLOOR(Offset / 10));
[0137] if the Periodicity is larger than sf5:
[0138] subframe = Offset mod 10;
[0139] else:
[0140] subframe=Offset or(Offset+5);
[0141] with T=CEIL(Periodicity / 10).
[0142] Here, mod represents the modulo operation, FLOOR() represents the floor function, and CEIL() represents the floor function. Offset represents the SMTC window offset, that is, the offset of the SMTC window relative to the system frame. Periodicity represents the SMTC window period. sf5 represents 5ms.
[0143] (2) When the configuration information of the first SMTC is activated, the terminal device sets up an additional SMTC for the cells in the cell identifier list in the configuration information based on the configuration information of the first SMTC. The SFN and subframe of the first subframe of each SMTC can be calculated according to the above formula.
[0144] If the terminal device activates the configuration information of the second SMTC but not the configuration information of the first SMTC, then the terminal device sets the SMTC according to the configuration information of the second SMTC. The SFN and subframe of the first subframe of each SMTC can be calculated according to the above formula.
[0145] In steps 402a and 402b, the terminal device measures the on-demand SSB to obtain the measurement results of the secondary cell; the terminal device measures the adaptive SSB to obtain the measurement results of the adaptive SSB or the measurement results of the serving cell.
[0146] Before sending the first signaling to the terminal device, the network device may send a first RRC signaling to the terminal device. The first RRC signaling indicates the configuration information of the first SMTC. The configuration information of the second SMTC may or may not be indicated by the first RRC signaling. Given whether the configuration information of the first and second SMTCs is indicated by the same RRC signaling, and considering that the first RRC signaling indicates one or more sets of additional SMTC configuration information, the following methods can be used:
[0147] In Method 1, the measurement object where the configuration information of the first SMTC is located is the same as the measurement object where the configuration information of the second SMTC is located. The first RRC signaling indicates the configuration information of the first SMTC and the configuration information of the second SMTC. The configuration information of the first SMTC is applicable to any transmission cycle in the transmission cycle list of the first SSB.
[0148] The measurement object (MeasObject, MO) containing the configuration information of the first SMTC is the same as that containing the configuration information of the second SMTC. In other words, the first RRC signaling can indicate the configuration information of both the first and second SMTCs. In other words, the configuration information of the first and second SMTCs is configured in the same measurement object. Therefore, the basic configuration information of the first SSB is the same as that of the second SSB, such as the same SSB frequency point and the same subcarrier spacing.
[0149] The configuration information of the second SMTC may include one or more of the following: the window period of the second SMTC, the window offset of the second SMTC, and the window duration of the second SMTC. The window of the second SMTC is used to measure the periodic SSB, i.e., the second SSB. When the first signaling instructs the deactivation of the configuration information of the reference SMTC, the window of the second SMTC is also used to measure the first SSB. The window period of the second SMTC represents the window period of the SMTC for measuring the periodic SSB. The window offset of the second SMTC represents the offset of the window of the SMTC for measuring the periodic SSB relative to the system frame. The window duration of the second SMTC represents the window duration of the SMTC for measuring the periodic SSB.
[0150] The configuration information of the first SMTC may include one or more of the following: a list of cell identifiers, the window period of the first SMTC, the window offset of the first SMTC, the window duration of the first SMTC, and the SSB to be measured. The window of the first SMTC is used to measure either the on-demand SSB or the adaptive SSB, i.e., the first SSB. The window period of the first SMTC represents the window period of the SMTC measuring the first SSB. The window offset of the first SMTC represents the offset of the window of the SMTC measuring the first SSB relative to the system frame. The window duration of the first SMTC represents the window duration of the SMTC measuring the first SSB.
[0151] The cell identifier list can be a list of physical cell identities (PCIs), and the cells in this list can apply the configuration information of the first SMTC. In other words, for the first SSB of a cell in this list, the terminal device can measure the first SSB within the window of the first SMTC. The SSB to be measured indicates which SSBs need to be measured, and may include the first SSB. For example, the configuration information of the first SMTC may include one or more SSB burst identifiers, and the SSB burst indicated by the SSB burst identifier is the SSB to be measured.
[0152] The configuration information of the first SMTC is for illustrative purposes only and does not constitute a limitation on the embodiments of this application. For example, it may also include the type of the first SSB, i.e., indicating whether it is a measurement-on-demand SSB or an adaptive SSB.
[0153] Optionally, the network device may also send a list of SSB transmission cycles for the first SSB to the terminal device, the list of SSB transmission cycles including multiple SSB transmission cycles. The first SSB transmission cycle indicated by the first signaling is one of the multiple SSB transmission cycles. Optionally, the network device may send the list of SSB transmission cycles for the first SSB to the terminal device via a second RRC signaling. Optionally, the list of SSB transmission cycles for the first SSB may be pre-defined by a protocol.
[0154] When the first signaling indicates the activation of the reference SMTC configuration information and indicates the first SSB transmission period, the terminal device measures the first SSB based on the first SMTC configuration information and the first SSB transmission period. In other words, it measures the first SSB of the first SSB transmission period based on the first SMTC configuration information.
[0155] The configuration information of the first SMTC applies to each SSB transmission cycle in the SSB transmission cycle list. The terminal device can measure the first SSB for different SSB transmission cycles based on the configuration information of the first SMTC.
[0156] The second RRC signaling can be the same as the first RRC signaling, or it can be different RRC signaling. For example, if the first and second RRC signaling are the same RRC signaling, the portion of the measurement object configured in this RRC signaling can be as follows:
[0157] MO: {
[0158] ssbfre
[0159] SMTC{Configuration 0}
[0160] SMTCn{Configuration 1}
[0161] }
[0162] ssbperioritylist SEQUENCE(SIZE(1..N))OF ssbperiority
[0163] Ssbperiority ENUMERATED{period 1, period 2, period 3}
[0164] Wherein, ssbfre represents the SSB frequency point, that is, the SSB frequency point of the first SSB and the second SSB. SMTC{configuration0} represents the configuration information of the second SMTC. SMTCn{configuration1} represents the configuration information of the first SMTC, that is, the configuration information of the additional SMTC is configuration 1. ssbperioritylist represents the transmission cycle list of the first SSB. Ssbperiority ENUMERATED{cycle 1, cycle 2, cycle 3} represents the three enumerated transmission cycles, that is, the transmission cycle list of the first SSB can be represented as {cycle 1, cycle 2, cycle 3}.
[0165] Method 2: The measurement object where the configuration information of the first SMTC is located is the same as the measurement object where the configuration information of the second SMTC is located. The first RRC signaling indicates the configuration information list and the configuration information of the second SMTC. The configuration information list includes the configuration information of the first SMTC. The configuration information of different SMTCs corresponds to different transmission periods.
[0166] The difference between Method 2 and Method 1 is that in Method 1, the first RRC signaling only indicates the configuration information of the first SMTC and the second SMTC, while in Method 2, the first RRC signaling indicates a list of configuration information. Each configuration information in this list can be used to measure the first SSB, and different configuration information corresponds to different transmission periods. Here, the transmission period refers to the transmission period of the first SSB.
[0167] The configuration information for the second SMTC can be found in the detailed description in Method 1, and will not be repeated here.
[0168] The configuration information list includes configuration information for multiple SMTCs, each used to measure the first SSB. However, the transmission period corresponding to the configuration information of each SMTC is different. For example, the configuration information list can be represented as {configuration information #0, configuration information #1, configuration information #2}, and the transmission period list for the first SSB can be represented as {period #0, period #1, period #2}, where configuration information #0 corresponds to period #0, configuration information #1 corresponds to period #1, and configuration information #2 corresponds to period #2. Configuration information #0 corresponding to period #0 indicates that configuration information #0 is used to measure the first SSB in period #0. The configuration information for each SMTC may include one or more of the following: the SMTC's window period, the SMTC's window offset, and the SMTC's window duration.
[0169] Optionally, the network device may also send a list of SSB transmission cycles for the first SSB to the terminal device. This list of SSB transmission cycles includes multiple SSB transmission cycles. The first SSB transmission cycle indicated by the first signaling is one of the multiple SSB transmission cycles. That is, there is a correspondence between the transmission cycles in the list of transmission cycles for the first SSB and the configuration information in the configuration information list. Optionally, the network device may send the list of SSB transmission cycles for the first SSB to the terminal device via a second RRC signaling. Optionally, the list of SSB transmission cycles for the first SSB may be pre-defined by the protocol.
[0170] When the first signaling instruction activates the configuration information of the reference SMTC and indicates the first SSB transmission period, the terminal device determines the configuration information of the SMTC corresponding to the first SSB transmission period, assuming it is the configuration information of the first SMTC, and measures the first SSB based on the configuration information of the first SMTC and the first SSB transmission period. In other words, it measures the first SSB of the first SSB transmission period based on the configuration information of the first SMTC.
[0171] The second RRC signaling can be the same as the first RRC signaling, or it can be different RRC signaling. For example, if the first and second RRC signaling are the same RRC signaling, the portion of the measurement object configured in this RRC signaling can be as follows:
[0172] MO: {
[0173] SMTC{Configuration 0}
[0174] SMTCnlist SEQUENCE(SIZE(1..N))OF SMTCn
[0175] }
[0176] ssbperioritylist SEQUENCE(SIZE(1..N))OF ssbperiority
[0177] Ssbperiority ENUMERATED{period 1, period 2, period 3}
[0178] Here, SMTC{configuration0} represents the configuration information of the second SMTC. SMTCnlist represents the configuration information list, i.e., the configuration information list of the additional SMTCs. ssbperioritylist represents the transmission cycle list of the first SSB. SsbperiorityENUMERATED{cycle 1, cycle 2, cycle 3} represents the three enumerated transmission cycles, that is, the transmission cycle list of the first SSB can be represented as {cycle 1, cycle 2, cycle 3}.
[0179] Method 3: The measurement object where the configuration information of the first SMTC is located is different from the measurement object where the configuration information of the second SMTC is located.
[0180] In other words, the configuration information of the first SMTC is indicated through an RRC signaling, which configures a measurement object; the configuration information of the second SMTC is indicated through another RRC signaling or the same RRC signaling, but the configuration information of the second SMTC is configured for a different measurement object. It can be understood that methods 1 and 2 indicate the configuration information of the first and second SMTCs within the same measurement object, while method 3 configures a measurement object for the first SSB. Thus, different measurement objects can have different basic configuration information, such as different SSB frequencies or different subcarrier spacing.
[0181] The first RRC signaling indicates the configuration information of the first SMTC. That is, the measurement object configured by the first RRC signaling includes the configuration information of the first SMTC. Optionally, the measurement object may include the configuration information of multiple SMTCs, with different configuration information corresponding to different transmission periods.
[0182] Optionally, the measurement object may also include the SSB transmission cycle list of the first SSB. Alternatively, the network device sends a second RRC signaling to the terminal device, the second RRC signaling including the SSB transmission cycle list of the first SSB. Alternatively, the SSB transmission cycle list of the first SSB may be pre-defined by the protocol.
[0183] For example, the content of the measurement object configured in the first RRC signaling can be as follows:
[0184]
[0185]
[0186]
[0187]
[0188]
[0189]
[0190] Wherein, ssbFrequency represents the SSB frequency of the first SSB. ssbSubcarrierSpacing represents the subcarrier spacing of the first SSB. smtc1 represents the configuration information of one SMTC used to measure the first SSB. smtc2 represents the configuration information of another SMTC used to measure the first SSB.
[0191] In Mode 3, when the first signaling indicates the activation of the reference SMTC's configuration information and indicates the first SSB transmission period, the terminal device can determine the SMTC configuration information corresponding to the first SSB transmission period from the measurement object, assuming it is the configuration information of the first SMTC, and measure the first SSB based on the configuration information of the first SMTC and the first SSB transmission period. In other words, the first SSB of the first SSB transmission period is measured based on the configuration information of the first SMTC.
[0192] exist Figure 4 In the illustrated embodiment, the configuration information of the SMTC for the first SSB is activated or deactivated by the first signaling instruction, so that the terminal device can measure the first SSB based on the configuration information of the SMTC for the first SSB, or based on the configuration information of the second SMTC, thereby enabling the terminal device to measure the SSB on demand or adaptively.
