Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technology, and in particular to a communication method and apparatus. Background Technology
[0002] Currently, when the time division duplex (TDD) uplink / downlink ratios (UL / DL patterns) of adjacent base station cells are different, the data transmission of the first terminal device in one cell may interfere with the data transmission of the second terminal device in another cell. This interference can be called cross-link interference (CLI).
[0003] To mitigate the impact of CLI (Collateral Lifting) on network devices, network equipment can configure CLI measurements for the second terminal device, allowing it to measure a configured reference signal. The reference signal measured by the second terminal device is the one sent to the network device by the first terminal device. The second terminal device obtains the measurement result of the reference signal and performs layer 3 filtering. The second terminal device can report the filtered CLI measurement results, and the network device can coordinate and schedule the second terminal device based on these results to mitigate or avoid CLI.
[0004] In wireless communication systems, to save power consumption of terminal devices while ensuring effective data transmission, discontinuous reception (DRX) mode is introduced. In DRX mode, the terminal device can listen to the physical downlink control channel (PDCCH) during the active period to transmit data with network devices, and sleep during other times.
[0005] However, since the terminal device is controlled by DRX when sending reference signals, the validity of CLI measurements may be affected. Summary of the Invention
[0006] This application provides a communication method and apparatus to improve the effectiveness of CLI measurements.
[0007] Firstly, embodiments of this application provide a communication method. This method can be executed by a first terminal device in this application. In this method, the first terminal device can receive a resource configuration. The resource configuration may include a parameter of the period of a target resource. The target resource may be a resource used for CLI measurements, or it may be a resource other than one used for CLI measurements. Wherein, when the target resource is a resource used for CLI measurements, the target resource may be a periodic sounding reference signal (SRS) resource or a semi-persistent SRS resource. The first terminal device can transmit the target resource according to the parameter of the period during an inactive time. The inactive time may be the inactive time of the first terminal device during discontinuous reception (DRX).
[0008] Based on this scheme, the first terminal device can send the target resources during the non-activation period, which can avoid the problem of CLI measurement failure caused by the DRX affecting the resources used for CLI measurement, which can only be sent during the DRX activation period. This can improve the effectiveness of CLI measurement.
[0009] In one possible implementation, the first terminal device may also send the target resource according to the period parameters during the DRX activation time.
[0010] Based on this scheme, the first terminal device can also send target resources according to the periodic parameters during the DRX activation or deactivation time. The first terminal device can send target resources without being controlled by DRX, which can improve the effectiveness of CLI measurement.
[0011] In one possible implementation, the first terminal device may determine the target resource from one or more resources indicated by the resource configuration.
[0012] Based on this scheme, if the resource configuration indicates multiple resources, the first terminal device can determine the target resource for CLI measurement among the multiple resources and send the target resource during the DRX inactive or active time.
[0013] In one possible implementation, the resource configuration may further include first indication information; the first indication information may be used to indicate the target resource.
[0014] Based on this scheme, the first terminal device can determine the target resource through the first indication information carried in the resource configuration, which can reduce information interaction with network devices and save signaling overhead.
[0015] In one possible implementation, the first terminal device may also receive first indication information; the first indication information may be used to indicate the target resource.
[0016] Based on this scheme, the first terminal device can determine the target resource for CLI measurement from one or more resources according to the first indication information sent by the network device, and send the target resource during the DRX inactive time or active time.
[0017] In one possible implementation, the resource configuration may include the identifiers of one or more resources; the first indication information may be used to indicate the identifier of the target resource.
[0018] Based on this scheme, one or more resources can be indicated by the identifier of one or more resources, and the first terminal device can also determine the target resource for CLI measurement from one or more resources according to the identifier of the target resource indicated by the first indication information.
[0019] In one possible implementation, the first indication information is further used to trigger the first terminal device to send the target resource according to the parameters of the period during the DRX inactivity period. In one example, the target resource can also be indicated by the first indication information, and the first terminal device can determine the target resource based on the first indication information and send the target resource during the DRX inactivity period according to the first indication information. In another example, the target resource used for CLI measurement can be predetermined, such as that specified by the protocol, and the first terminal device can send the protocol-specified target resource during the DRX inactivity period according to the first indication information.
[0020] Based on this scheme, the first terminal device can determine that the transmission of the target resource is not controlled by DRX through the indication of the first indication information. The first terminal device can transmit the target resource during the inactive time of DRX, which can improve the effectiveness of CLI measurement.
[0021] In one possible implementation, the first terminal device may also receive second indication information; this second indication information can be used to instruct the first terminal device to send the target resource according to the parameters of the period during the DRX activation time. For example, the second indication information may instruct the first terminal device to send the target resource during the DRX activation time, and not to send the target resource during the DRX inactivation time.
[0022] Based on this scheme, after CLI measurement is completed, the first terminal device can determine that the transmission of the target resource is controlled by DRX according to the second indication information. The target resource can be transmitted during the DRX activation time and not transmitted during the DRX deactivation time, which can save the power consumption of the first terminal device.
[0023] Secondly, embodiments of this application also provide another communication method. This method can be executed by a first network device in this application embodiment. In this method, the first network device can send a resource configuration; the resource configuration is used to indicate one or more resources. The first network device can also send first indication information, which can be used to determine a target resource among the one or more resources. The target resource here can be a periodic SRS resource or a semi-persistent SRS resource. The target resource is a resource sent by the first terminal device during the DRX inactivity period.
[0024] Based on this scheme, the first network device can indicate one or more resources to the first terminal device through resource configuration, and can also indicate the target resources for CLI measurement to the first terminal device through the first indication information, so that the first terminal device can send the target resources during the DRX inactive time, which can improve the effectiveness of CLI measurement.
[0025] In one possible implementation, the target resource is still the resource sent by the first terminal device during the DRX activation time.
[0026] Based on this scheme, the first network device can instruct the first terminal device to send the target resource without being controlled by DRX through the first indication information, so that the first terminal device sends the target resource during both the DRX activation and inactivation times for CLI measurement.
[0027] In one possible implementation, the first indication information can also be used to trigger the first terminal device to send the target resource during the DRX inactivity period. In one example, the first indication information can indicate the target resource, so that the first terminal device determines the target resource upon receiving the first indication information and sends the target resource during the DRX inactivity period. In another example, the target resource can be predetermined, such as being defined by a protocol, and the first network device can use the first indication information to instruct the first terminal device to send the protocol-defined target resource during the DRX inactivity period.
[0028] Based on this scheme, the first network device can instruct the first terminal device to send the target resource during the DRX inactive time through the first indication information, which can improve the effectiveness of CLI measurement.
[0029] In one possible implementation, the first network device may also send a second instruction message, which may be used to instruct the first terminal device to send the target resource during the DRX activation time.
[0030] Based on this scheme, the first network device can use the second indication information to instruct the first terminal device to send the target resource under the control of DRX, so that the first terminal device sends the target resource during the DRX activation time and does not send the target resource during the DRX deactivation time, thereby saving the power consumption of the first terminal device.
[0031] Thirdly, embodiments of this application also provide another communication method, which can be executed by a second terminal device provided in embodiments of this application. In this method, the second terminal device can receive a measurement resource configuration, which can be used to indicate measurement resources. The second terminal device can measure the measurement resources, and can also filter the obtained first target measurement result. The first target measurement result can satisfy a first condition. For example, the first condition may include at least one of the following:
[0032] 1. The measurement result is greater than or equal to a first threshold. This first threshold can be predetermined based on experience, such as -98dB. If the measurement result obtained by the second terminal device from measuring the resource is greater than -98dB, the second terminal device can filter the measurement result. Alternatively, the first threshold can be indicated by the second network device, determined by the second terminal device itself, or specified by the protocol; this application does not impose specific limitations.
[0033] 2. The difference between the measurement result and the first measurement result is less than or equal to the second threshold. The first measurement result is the result of the previous measurement of the corresponding measurement. For example, if the second terminal device performs a measurement on the measurement resource (the first measurement), and then performs another measurement on the same resource (the second measurement), the result of the first measurement can be considered the first measurement result. It should be understood that the second threshold can be predetermined based on empirical values, indicated by the second network device, determined by the second terminal device itself, or specified by the protocol; this application does not impose specific limitations.
[0034] 3. The second terminal device can also receive DRX information of the measurement resources. The first target measurement result can be a measurement obtained within the DRX activation time indicated by the DRX information. Here, the DRX activation time can be the time including only the runtime of the DRX-on Duration Timer. The DRX information of the measurement resource can refer to the DRX information of the terminal device sending the measurement resource. For example, if the measurement resource included in the measurement configuration is a resource sent by a third terminal device, then the DRX information of the measurement resource can refer to the DRX information of the third terminal device. It should also be noted that one measurement resource can correspond to one DRX information, or multiple measurement resources can correspond to one DRX information.
[0035] Based on this scheme, when filtering measurement results, the second terminal device can filter measurement results that meet the first condition, which can reduce the impact of abnormal measurement results on CLI measurement, thereby reducing the impact of DRX on CLI measurement accuracy and improving CLI measurement accuracy.
[0036] In one possible implementation, the second terminal device can adjust the filtering coefficients to filter the measurement results of the second target. Here, the second target measurement result is a measurement result other than the first target measurement result.
[0037] Based on this scheme, the second terminal device can adjust the filtering coefficient when filtering the measurement results of the second target, thereby reducing the impact of abnormal measurement results on CLI measurement and thus reducing the impact of DRX on the accuracy of CLI measurement.
[0038] In one possible implementation, the second terminal device can also receive DRX information of the measurement resource. When measuring the measurement resource, the second terminal device can perform the measurement within the DRX activation time indicated by the DRX information. Here, the DRX activation time can be the time that includes only the runtime of the DRX-on Duration Timer.
[0039] Based on this scheme, the second terminal device only measures the measurement resources during the DRX activation time indicated by the DRX information, which can reduce the impact of DRX on the accuracy of CLI measurements.
[0040] Fourthly, embodiments of this application also provide another communication method, which can be executed by the second network device provided in the embodiments of this application. In this method, the second network device can send a measurement resource configuration, which includes measurement resources. The second network device can also send DRX information of the measurement resources. Here, the measurement resources can be resources of a terminal device connected to the third network device, and the DRX information can be the DRX information of the terminal device connected to the third network device.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0071] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.
[0072] 1) Discontinuous reception (DRX) is a data transmission method introduced by communication systems to save power consumption of terminal equipment. In DRX mode, the terminal equipment can listen to the physical downlink control channel (PDCCH) during the active time.
[0073] 2) Activation time can refer to the activation time within a DRX cycle. This can include the runtime of the DRX-on Duration Timer, the DRX-Inactivity Timer, the DRX-Retransmission Timer (DL), the DRX-Retransmission Timer (UL), or the random access contention resolution timer (ra). Activation time can also include the time during which a scheduling request (SR) is sent on the physical uplink control channel (PUCCH) and is awaiting processing, and the time after a successful receipt of a random access response (RAR) in a non-contention-based random access procedure, before receiving a PDCCH scrambled with the cell-radio network temporary identifier (C-RNTI) indicating a new transmission.
[0074] 3) Inactive time can refer to any time within the DRX cycle other than the active time. Alternatively, it can refer to the time within the DRX cycle when the terminal device does not listen to the PDCCH. For example, within the DRX cycle, the terminal device can listen to the PDCCH during the active time, or it can listen to the PDCCH according to the requirements of other procedures. In this case, inactive time can be any time other than the active time and the time spent listening to the PDCCH according to the requirements of other procedures. These other procedures could be, for example, the random access procedure. During the random access procedure, when the random access response window timer (ra-ResponseWindow) is running, the terminal device needs to listen to the PDCCH regardless of whether it is the DRX active time.
[0075] 4) Network devices, including access network (AN) devices, can refer to devices in the access network that communicate with wireless terminals via one or more cells over the air interface, such as base stations or access points, and roadside units (RSUs) in vehicle-to-everything (V2X) technology. Base stations can be used to convert received air frames to and from IP packets, acting as routers between terminals and the rest of the access network, which may include IP networks. RSUs can be fixed infrastructure entities supporting V2X applications and can exchange messages with other entities supporting V2X applications. Network devices can also coordinate the management of air interface attributes. For example, network equipment may include evolved base stations (NodeBs, eNBs, or e-NodeBs) in long-term evolution (LTE) systems or long-term evolution-advanced (LTE-A) systems, or may include next-generation node Bs (gNBs) in evolved packet core (EPC), the 5th generation (5G), or new radio (NR) systems (also referred to as NR systems), or may include centralized units (CUs) and distributed units (DUs) in cloud radio access networks (Cloud RAN) systems. The embodiments of this application are not limited.
[0076] Network equipment may also include core network equipment, such as access and mobility management functions (AMF).
[0077] In this application embodiment, the device for implementing the network device function can be a network device itself, or a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the network device function is used to describe the technical solutions provided in this application embodiment.
[0078] 5) Terminal equipment, including equipment that provides voice and / or data connectivity to users. Specifically, it includes equipment that provides voice connectivity to users, or equipment that provides data connectivity to users, or equipment that provides both voice and data connectivity to users. For example, it may include a handheld device with wireless connectivity or a processing device connected to a wireless modem. The terminal can communicate with the core network via a radio access network (RAN), exchanging voice or data with the RAN, or interacting with the RAN for both voice and data. The terminal may include user equipment (UE), wireless terminal, mobile terminal, device-to-device (D2D) terminal, vehicle-to-everything (V2X) terminal, machine-to-machine / machine-type communications (M2M / MTC) terminal, Internet of Things (IoT) terminal, subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user device, etc. For example, it may include mobile phones (or "cellular" phones), computers with mobile terminals, portable, pocket-sized, handheld, or computer-embedded mobile devices, etc. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). It also includes limited devices, such as those with low power consumption, limited storage capacity, or limited computing power. Examples include information sensing devices such as barcode scanners, radio frequency identification (RFID), sensors, global positioning systems (GPS), and laser scanners.
[0079] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, bracelets, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.
[0080] The various terminals described above, if located in a vehicle (e.g., placed inside or installed inside a vehicle), can be considered vehicle-mounted terminals, also known as on-board units (OBUs).
[0081] In this application embodiment, the device for implementing the terminal device function can be a terminal, or a device capable of supporting the terminal in implementing the function, such as a chip system, which can be installed in the terminal. In this application embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. In the technical solutions provided in this application embodiment, the device for implementing the terminal function is a terminal, as an example, to describe the technical solutions provided in this application embodiment.
[0082] In the description of this application, the terms "first," "second," etc., are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance or order.
[0083] Furthermore, in the embodiments of this application, the term "exemplary" is used to indicate that it is an example, illustration, or description. Any embodiment or implementation described as "exemplary" in this application should not be construed as being more preferred or advantageous than other embodiments or implementations. Rather, the use of the term "exemplary" is intended to present the concept in a specific manner.
[0084] To facilitate understanding of the embodiments of this application, let's first take... Figure 1 The communication system shown in the figure is used as an example to describe in detail the communication system applicable to the embodiments of this application. Figure 1 A schematic diagram of a communication system applicable to the communication method of embodiments of this application is shown. For example... Figure 1As shown, the communication system may include a network device 102 and a terminal device 104. The network device 102 may be configured with multiple antennas, and the terminal device 104 may also be configured with multiple antennas.
[0085] It should be understood that network device 102 may also include multiple components related to signal transmission and reception (e.g., processor, modulator, multiplexer, demodulator or demultiplexer, etc.).
[0086] In this communication system, network device 102 can communicate with multiple terminal devices (e.g., terminal device 104 shown in the figure). Network device 102 can communicate with one or more terminal devices similar to terminal device 104.
[0087] In this communication system, network device 102 can send resource configuration to terminal device 104, which may include parameters for the period of the target resource. Terminal device 104 can send the target resource according to the period parameters during the DRX inactivity period.
[0088] like Figure 2 As shown, the communication system may also include a first network device 202, a second network device 204, a first terminal device 203, and a second terminal device 205.
[0089] The second network device 204 can send a measurement resource configuration, which includes measurement resources, to the second terminal device 205. The second network device 204 can also send an indication message to the first network device 202, notifying the first network device 202 that the second network device 204 has sent a measurement resource configuration to the second terminal device 205, and specifying the measurement resources included in the configuration. Upon receiving the indication message, the first network device 202 can send a resource configuration to the first terminal device. This resource configuration may include target resources. It should be noted that the target resources and measurement resources can be the same or different resources.
[0090] It should be understood that the technical solution of this application can be applied to wireless communication systems, for example, Figure 1 The communication system 100 shown may include at least one network device and at least one terminal device, which can communicate wirelessly over an air interface. For example, the network device in this communication system may correspond to... Figure 1 The network device 102 shown can correspond to the terminal device. Figure 1 The terminal device 104 shown. Alternatively, it can also be applied to... Figure 2The communication system shown may include at least two network devices and at least two terminal devices, which can communicate wirelessly over an air interface. For example, the network devices in this communication system may correspond to... Figure 2 The first network device 202 and the second network device 204 shown herein, the terminal device can correspond to Figure 2 The first terminal device 203 and the second terminal device 205 shown in the figure.
[0091] Currently, time division duplexing (TDD) is a duplexing method in communication systems that uses time division to achieve uplink and downlink transmission. For example... Figure 3 As shown, in TDD mode, reception (downlink) and transmission (uplink) in a communication system are performed at different times on the same frequency channel. That is, for a certain channel, the channel is used as an uplink channel for a certain period of time, while it is used as a downlink channel for another period of time.
[0092] like Figure 3 As shown, in TDD mode, time resources need to be allocated in both uplink and downlink directions. That is, the network needs to allocate specific time periods for uplink transmission and downlink transmission to the terminal devices. This allocation of time resources is called the TDD uplink / downlink ratio. Different cells can use different TDD uplink / downlink ratios. For example... Figure 4 As shown, cell 1 and cell 2 use different TDD uplink and downlink ratios.
[0093] However, when the TDD uplink / downlink ratios differ between adjacent base station cells, data transmission within one cell may interfere with data transmission in another cell. For example... Figure 5 As shown, assume that terminal device 1 serves cell A under network device A, and terminal device 2 serves cell B under network device B. Cell A and cell B are two adjacent cells. Terminal device 1 is located at the edge of cell A, and terminal device 2 is located at the edge of cell B, with a small distance between them. In this case, cross-link interference (CLI) may occur as shown below:
[0094] 1. From the perspective of the terminal devices: Terminal device 1 is performing uplink (UL) transmission. Since terminal device 1 is located at the edge of cell A, its transmission power for UL transmission may be relatively high to ensure that UL data can be sent to the network device normally. Meanwhile, terminal device 2 is currently performing downlink (DL) transmission. Since terminal device 2 is also located at the edge of cell B, and is farther from the network device, the DL data sent from cell B to terminal device 2 may have lower power when it reaches terminal device 2 after path loss. Therefore, when terminal device 1's UL transmission and terminal device 2's DL transmission occur simultaneously, terminal device 1's UL transmission may interfere with terminal device 2's DL transmission, causing terminal device 2 to be unable to correctly receive and decode the DL data sent from cell B.
[0095] 2. From the perspective of network equipment: Cell B is sending DL data to terminal device 2. Since terminal device 2 is located at the edge of cell B, the power of cell B sending DL data may be relatively high to ensure that the DL data can be sent to terminal device 2 normally. Meanwhile, cell A is receiving UL data sent by terminal device 1. Terminal device 1 is also located at the edge of cell A. Due to the distance from the network equipment, the UL data sent by terminal device 1 to cell A may have lower power when it reaches cell A after path loss. Therefore, when cell B's DL data transmission and cell A's UL data reception occur simultaneously, cell B's transmission may interfere with cell A's reception, causing cell A's base station to be unable to correctly receive and decode the UL data sent by terminal device 1.
[0096] To mitigate the impact of CLI (Clipped Link Inquiry), network devices can configure CLI measurements for terminal devices. These terminal devices measure a configured reference signal, perform layer 3 filtering on the measurement results, and then report the filtered CLI measurement results. The network device can then coordinate scheduling based on the information reported by the terminal devices to reduce CLI impact. For example, ... Figure 4 As shown, cell B can be configured with terminal device 2 to perform CLI measurements, allowing terminal device 2 to measure the reference signal sent by terminal device 1 to cell A. Currently, depending on the type of reference signal measured by CLI, it can be divided into CLI sounding reference signal (SRS) - reference signal received power (RSRP) measurement and CLI - received signal strength indicator (RSSI) measurement.
[0097] Currently, SRS can include periodic SRS, semi-persistent SRS, and aperiodic SRS. For periodic and semi-persistent SRS, the terminal device sends SRS periodically according to the parameters configured in the network device. However, the transmission of both periodic and semi-persistent SRS is subject to DRX control. Specifically, during DRX activation periods, the terminal device can send periodic or semi-persistent SRS, while during DRX inactivation periods, the terminal device cannot send periodic or semi-persistent SRS.
[0098] However, for SRS resources in CLI SRS-RSRP measurements, due to the influence of DRX, SRS may not be sent accurately according to the SRS cycle, thus affecting the accuracy of CLI measurements. The measurement results reported by the terminal device may also be inaccurate, which may lead to network devices misjudging interference.
[0099] In view of this, embodiments of this application provide a communication method that can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, future 5th Generation (5G) systems, such as new radio access technology (NR), and future communication systems such as 6G systems.
[0100] This application will present various aspects, embodiments, or features relating to systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and / or may not include all the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches are also possible.
[0101] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0102] This application's embodiments can be applied to both traditional typical networks and future UE-centric networks. UE-centric networks introduce a non-cell network architecture, deploying a large number of small cells within a specific area to form a hypercell. Each small cell serves as a transmission point (TP) or transmission and reception point (TRP) within the hypercell and is connected to a centralized controller. When a UE moves within the hypercell, network devices continuously select new sub-clusters to serve it, thus avoiding actual cell handover and ensuring UE service continuity. These network devices include wireless network equipment. Alternatively, in a UE-centric network, multiple network devices, such as small cells, can have independent controllers, such as a distributed controller. Each small cell can independently schedule users, and long-term interaction between small cells provides flexibility in providing collaborative services to the UE.
[0103] In this application embodiment, different base stations can be base stations with different identifiers, or they can be base stations with the same identifier deployed in different geographical locations. Since a base station does not know whether it will be involved in the scenario applied in this application embodiment before deployment, it is understood that the aforementioned base stations with different identifiers can be base station identifiers, cell identifiers, or other identifiers.
[0104] In this application, some scenarios are illustrated using NR networks in wireless communication networks as examples. It should be noted that the solutions in this application can also be applied to other wireless communication networks, and the corresponding names can be replaced by the names of the corresponding functions in other wireless communication networks.
[0105] Figure 6 This is an exemplary flowchart illustrating the communication method provided in this application embodiment from the perspective of device interaction. For example... Figure 6 As shown, the method may include:
[0106] Step 601: The first network device sends resource configuration to the first terminal device.
[0107] The resource configuration may include parameters regarding the period of the target resource. The target resource may be at least one of a periodic SRS and a semi-persistent SRS. The first terminal device may determine the target resource from one or more resources indicated in the resource configuration. The following describes in detail the method by which the first terminal device determines the target resource, which may include the following methods 1-3:
[0108] Method 1: The first terminal device can determine the target resource based on the resource configuration.
[0109] The resource configuration here may include one or more resource sets, and each resource set may include one or more resources.
[0110] When sending resource configuration, the first network device can indicate the target resource by naming the resource set or by naming the resource itself. For example, if the name of a resource set contains "CLI", all resources in that resource set can be considered target resources; if the name of a resource contains "CLI", that resource can be considered a target resource.
[0111] For example, if the resource configuration sent by the first network device contains multiple resource sets, one of which is named "CLI SRS resource set", then the first terminal device can consider all resources contained in this resource set to be target resources. Alternatively, if the resource configuration sent by the first network device contains resource set 1 and resource set 2, where resource set 1 contains 2 resources named "CLI SRS resource" and resource set 2 contains 3 resources named "CLI SRS resource", then the first terminal device can determine that the 5 resources named "CLI SRS resource" are target resources.
[0112] Method 2: The first terminal device can determine the target resource based on the resource configuration and the first instruction information.
[0113] The resource configuration here may include one or more resource sets, and each resource set may include one or more resources.
[0114] In one embodiment, the resource configuration may further include an identifier for a resource set, or an identifier for a resource. For example, the resource configuration includes two resource sets, namely resource set 1 and resource set 2. Alternatively, the resource configuration includes one resource set containing resource 1, resource 2, and resource 3. The first terminal device can determine the target resource from the resources indicated by the resource configuration based on the first indication information. The first indication information may include the identifier of the target resource, or it may include the identifier of the resource set. The first indication information may be sent by the first network device. When the first network device sends the first indication information, it may send it simultaneously with the resource configuration, or it may send it separately from the resource configuration. In one example, the first network device may send the first indication information to the first terminal device along with the resource configuration.
[0115] For example, the resource configuration received by the first terminal device includes resource set 1, resource set 2, and resource set 3. The first terminal device also receives first indication information, which includes resource set 1. Therefore, the first terminal device can determine that all resources in resource set 1 are target resources. Alternatively, the resource configuration received by the first terminal device includes resource 1, resource 2, resource 3, and resource 4. This resource configuration also includes first indication information, which includes resource 1 and resource 2. Therefore, the first terminal device can determine that resource 1 and resource 2 are target resources.
[0116] In another embodiment, a first indication information can be added to the resource configuration. This first indication information can be used to indicate whether a resource set is a resource set of a target resource, or it can be used to indicate whether a resource is a target resource. For example, if the relevant configuration information of a resource set contains the first indication information, then all resources in the resource set are target resources; if the relevant configuration information of a resource contains the first indication information, then that resource is a target resource.
[0117] For example, if the resource configuration received by the first terminal device includes resource set 1 and resource set 2, and the configuration information for resource set 1 includes the first indication information, while the configuration information for resource set 2 does not include the first indication information, then the first terminal device can determine that all resources in resource set 1 are target resources. Alternatively, if the resource configuration received by the first terminal device includes resource 1, resource 2, and resource 3, and the configuration information for resource 1 and resource 3 includes the first indication information, while the configuration information for resource 2 does not include the first indication information, then the first terminal device can determine that resource 1 and resource 3 are target resources.
[0118] In one example, the first indication information could be 1 bit. For instance, a "1" bit could indicate that the resource set contains the target resource, or that the resource is the target resource. A "0" bit could indicate that the resource set contains neither the target resource nor the resource is the target resource.
[0119] For example, if the resource configuration received by the first terminal device includes resource set 1 and resource set 2, where the configuration information for resource set 1 contains "1" and the configuration information for resource set 2 contains "0", then the first terminal device can determine that the resource included in resource set 1 is the target resource. Alternatively, if the resource configuration received by the first terminal device includes resource 1, resource 2, and resource 3, where the configuration information for resource 1 contains "1", the configuration information for resource 2 contains "1", and the configuration information for resource 3 contains "0", then the first terminal device can determine that resource 1 and resource 2 are the target resources.
[0120] Method 3: The first terminal device can determine the target resource according to the provisions of the protocol and the first instruction information.
[0121] The protocol here can be a protocol like the Third Generation Partnership Project (3GPP) protocol. This protocol can specify the target resources for the first terminal device. For example, it can specify the type of target resource, such as specifying periodic SRS and / or semi-persistent SRS as target resources. The first indication information here can be indication information used to trigger the first terminal device to send the target resource.
[0122] For example, if the first terminal device receives the first indication information sent by the first network device, then the first terminal device can determine that all periodic SRS and / or semi-persistent SRS are target resources from the resources already configured by the first network device, and send periodic SRS and / or semi-persistent SRS.
[0123] In this embodiment of the application, the first network device may also send resource configuration or first instruction information to the first terminal device according to the instructions of the second network device. For example... Figure 2 As shown, the second network device 204 can send first information to the first network device 202, instructing the second network device 204 to send measurement resource configuration to the second terminal device 205. This first instruction may include the measurement resources indicated by the second network device 204 to the second terminal device 205. The first network device 202 can send resource configuration or first instruction information to the first terminal device 203 based on this first information.
[0124] Step 602: During the DRX inactive time, the first terminal device sends the target resource according to the period parameters.
[0125] The first terminal device can determine the period of the target resource based on the period parameter. The period parameter can be a period identifier, such as 1 representing a period of 1 second and 2 representing a period of 2 seconds. Alternatively, the period parameter can be a duration, such as 1 second or 1.5 seconds.
[0126] In one embodiment, the first terminal device may maintain a timer that starts timing upon receiving resource configuration or a first indication message. For example, when the resource configuration indicates one or more resources, the first terminal device may start timing upon receiving the first indication message, and when the timing duration reaches the duration of the target resource's cycle, send the target resource and reset the timer. Alternatively, when the resource configuration indicates a target resource, the first terminal device may start timing upon receiving the resource configuration, and when the timing duration reaches the duration of the target resource's cycle, send the target resource and reset the timer.
[0127] In another embodiment, the first terminal device can calculate the time point for sending the target resource based on the period parameter. For example, it can calculate which frames and slots to send the target resource on based on the parameter.
[0128] like Figure 7 As shown, the first terminal device enters DRX mode at time t1, where t1-t2 is the DRX activation time and t2-t3 is the DRX deactivation time. The first terminal device can send target resources within t2-t3 according to the periodic parameters.
[0129] In this embodiment of the application, the first terminal device can also send the target resource during the DRX activation time. For example... Figure 8 As shown, the first terminal device enters DRX mode at time t1, where t1-t2 is the DRX activation time and t2-t3 is the DRX inactivity time. At time T1, the period of target resource 1 expires, and the first terminal device can send the target resource at time T1. At time T2, the period of target resource 1 expires again, and the first terminal device can send the target resource at time T2.
[0130] Based on this scheme, the first terminal device can send target resources without being controlled by DRX, and can send target resources during DRX activation or deactivation times, which can improve the accuracy of CLI measurements.
[0131] In this embodiment, the method can further execute step 603, whereby the second terminal device measures the target resource. Specifically, the second terminal device can perform CLI measurement based on the measurement resource configuration of the second network device, measuring the target resource sent by the first terminal device. The second terminal device can then filter the measurement results and send them to the second network device.
[0132] In one embodiment, the first network device may send second indication information to the first terminal device. This second indication information is used to instruct the first terminal device to send target resources according to period parameters during the DRX activation time. Figure 9 As shown, at time t1, the first terminal device receives the second indication information sent by the first network device. At time T1, the period of target resource 1 expires, and since time T1 is the active period of DRX, the first terminal device sends target resource 1 at time T1. At time T2, the period of target resource 1 expires again for the first terminal device, but since time T2 is the inactive period of DRX, the first terminal device does not send target resource 1 at time T2.
[0133] In one example, a first network device may send a second indication message to a first terminal device upon receiving a second message from a second network device. This second message may be used to notify the first network device that the CLI measurement configured by the second network device for the second terminal device has ended. This second message may also be used to trigger the first network device to send the second indication message to the first terminal device. Figure 2 As shown, the second terminal device 205 performs CLI measurements according to the measurement resource configuration sent by the second network device 204. After the second terminal device 205 completes the CLI measurement, the second network device 204 can send second information to the first network device 202. Upon receiving this second information, the first network device 202 can send second indication information to the first terminal device 203.
[0134] In this embodiment, the second information may further include measurement resources indicated by the second network device to the second terminal device, which can be used to indicate which measurement resources have been used for CLI measurements. Therefore, when the first network device receives the second information and sends the second indication information to the first terminal device, it can carry the measurement resources included in the second information in the second indication information. The first terminal device can then send the measurement resources included in the second indication information during the DRX activation time according to the second indication information.
[0135] Based on this scheme, when the CLI measurement ends, the first terminal device sends the target resource under DRX control. The first terminal device can send the target resource during the DRX activation time, which can save the power consumption of the first terminal device.
[0136] This application also provides another communication method. This communication method can be applied to, for example... Figure 1 The communication system shown describes a system in which network device 102 can send a measurement resource configuration, including measurement resources, to terminal device 104. Terminal device 104 can measure the measurement resources and obtain measurement results. Terminal device 104 can filter the measurement results and send the filtered results back to network device 102.
[0137] Figure 10 This is an exemplary flowchart illustrating the communication method provided in this application embodiment from the perspective of device interaction. The second terminal device can be, for example: Figure 1 The terminal device 104 shown, the second network device can be as follows: Figure 1 The network device 102 shown is an example. Figure 10 As shown, the following steps may be included:
[0138] Step 1001: The second network device sends the measurement resource configuration to the second terminal device.
[0139] The measurement resource configuration here can include measurement resources. For example, the measurement resource configuration can include the identifier of the measurement resource, or the time-domain configuration information and frequency-domain configuration information of the measurement resource, etc.
[0140] Step 1002: The second terminal device measures the measurement resources.
[0141] The second terminal device can perform CLI SRS-RSRP measurements on the measurement resources. The following details the methods used by the second terminal device to perform these measurements, which may include Measurement Method 1 and Measurement Method 2:
[0142] Measurement Method 1: The second terminal device can measure the measurement resources during the DRX activation time.
[0143] The activation time of DRX here can be the time that includes only the runtime of the DRX duration timer (drx-on DurationTimer).
[0144] In one embodiment, the second terminal device can receive DRX information of the measurement resource sent by the second network device. This DRX information can be the DRX information of the first terminal device that sent the measurement resource. The first terminal device can be a terminal device connected to the first network device. It should be understood that the second network device can obtain the DRX information of the first terminal device from the first network device and send the DRX information to the second terminal device. When measuring the measurement resource, the second terminal device can measure the measurement resource at the activation time represented by the DRX.
[0145] like Figure 2 As shown, the second network device 204 can request DRX information of the first terminal device 203 from the first network device 202. The first network device 202 can send the DRX information of the first terminal device 203 to the second network device 204, and the second network device 204 can send the DRX information of the first terminal device 203 to the second terminal device 205. The second terminal device 205 determines the activation time of the first terminal device 203 based on the DRX information, and performs measurement on the measurement resources during the activation time.
[0146] It should be understood that the DRX information in the embodiments of this application can be one measurement resource corresponding to one DRX information, or multiple measurement resources corresponding to one DRX information. For example, measurement resource 1 can correspond to DRX information 1, and measurement resources 2 and 3 can correspond to DRX information 2. The second terminal device can measure measurement resource 1 at the activation time indicated by DRX information 1, and measure measurement resources 2 and 3 at the activation time indicated by DRX information 2.
[0147] In one example, the measurement resource configuration also includes a parameter for the period of the measurement resource. The second terminal device can measure the measurement resource based on the period parameter and DRX information. The period parameter can be a period identifier or the duration of the period. In one embodiment, the second terminal device can maintain a timer that starts timing upon receiving the resource configuration and stops timing when the timing duration reaches the measurement period duration. The second terminal device can measure the measurement resource when the timing duration reaches the measurement period duration and then reset the timer. In another embodiment, the second terminal device can calculate the time points for measuring the measurement resource based on the period parameter. For example, it can calculate the time slots on which the measurement resource will be measured based on the parameter.
[0148] It should be understood that if the time point for measuring the measurement resource is determined to be during the DRX inactive period based on the period parameters, then the second terminal device may not measure the measurement resource at that time point. If the time point for measuring the measurement resource is determined to be during the DRX active period based on the period parameters, then the second terminal device may measure the measurement resource at that time point.
[0149] For example, the measurement resource configuration received by the second terminal device includes measurement resource 1, and the period of measurement resource 1 is 1. Figure 11 As shown, t1-t3 represents one DRX cycle, where t1-t2 is the active time and t2-t3 is the inactive time. At time T1, the measurement cycle for measurement resource 1 expires, and since T1 is within the DRX active time, the second terminal device can measure measurement resource 1 at time T1. At time T2, the measurement cycle for measurement resource 1 expires again, but since T2 is within the DRX inactive time, the second terminal device can choose not to measure measurement resource 1 at time T2.
[0150] Measurement Method 2: The second terminal device measures the measurement resources during the DRX activation and inactivation times.
[0151] The second terminal device can measure the resource based on a period parameter. This period parameter can be a period identifier or the duration of the period. In one embodiment, the second terminal device can maintain a timer that starts timing upon receiving resource configuration and stops timing when the timing duration reaches the measurement period duration. The second terminal device can then measure the resource and reset the timer when the timing duration reaches the measurement period duration. In another embodiment, the second terminal device can calculate the time points for measuring the resource based on the period parameter. For example, it can calculate the time slots at which the resource will be measured based on the parameter.
[0152] For example, the measurement resource configuration received by the second terminal device includes measurement resource 1 and the period 1 of measurement resource 1. Figure 12 As shown, when the timing duration reaches the measurement cycle at time T1, the second terminal device can measure measurement resource 1 at time T1 and reset the timer. When the timing duration reaches the measurement cycle at time T2, the second terminal device can measure measurement resource 1 at time T2 and reset the timer.
[0153] Step 1003: The second terminal device filters the measurement results.
[0154] The second terminal device can perform layer 1 filtering or layer 3 filtering on the measurement results. The filtering methods of the second terminal device are described below, including method 1 and method 2:
[0155] Filtering method 1: The second terminal device filters the measurement results of the first target.
[0156] The first target measurement result here can be a measurement result that satisfies the first condition. The first condition can include the following conditions 1-3:
[0157] Condition 1: The measurement result is greater than or equal to the first threshold.
[0158] For example, after the second terminal device measures the resource, if the measurement result is greater than or equal to the first threshold, the second terminal device can filter the measurement result. If the measurement result is less than the first threshold, the second terminal device can choose not to use the measurement result.
[0159] The first threshold here can be predetermined based on empirical values, or it can be indicated by the second network device, or it can be specified by the protocol, or it can be determined by the second terminal device itself. This application does not make any specific limitations.
[0160] Condition 2: The difference between the measurement result and the first measurement result is less than or equal to the second threshold.
[0161] The first measurement result here is the result of the previous measurement corresponding to the current measurement. For example... Figure 13As shown, the second network device measures the measurement resources at time T1, and the second terminal device also measures the measurement resources at time T2. Therefore, the measurement result at time T1 can be the first measurement result. Here, the value of the measurement result at time T1 can be the actual measurement result or the value after filtering. If the difference between the measurement result obtained at time T2 and the measurement result obtained at time T1 is less than or equal to a second threshold, the second terminal device can filter the measurement result obtained at time T2. If the difference between the measurement result obtained at time T2 and the measurement result obtained at time T1 is greater than the second threshold, the second terminal device can choose not to use the measurement result obtained at time T2.
[0162] The second threshold here can be predetermined based on empirical values, or it can be indicated by the second network device, or it can be specified by the protocol, or it can be determined by the second terminal device itself. This application does not make any specific limitations.
[0163] Condition 3: The measurement results are obtained during the DRX activation time as represented by the DRX information.
[0164] like Figure 11 As shown, if the measurement result is obtained between t1 and t2, the second terminal device can filter the measurement result; if the measurement result is obtained between t2 and t3, the second terminal device can choose not to use the measurement result.
[0165] Filtering method 2: The second terminal device filters the measurement results of the first target and the measurement results of the second target.
[0166] The first target measurement result here is the measurement result that satisfies the first condition, which can be as described in conditions 1-3 above, and will not be repeated here. The second target measurement result can be any measurement result other than the first target measurement result.
[0167] If the second terminal device measures the measurement resource and obtains a measurement result for the first target, the second terminal device can filter the first target measurement result. If the second terminal device measures the measurement resource and obtains a measurement result for the second target, the second terminal device can adjust the filtering coefficient and filter the second target measurement result according to the adjusted filtering coefficient. Figure 13As shown, at time T1, the second terminal device measures the measurement resource and obtains the measurement result of the first target. The second terminal device can filter this first target measurement result. At time T2, the second terminal device measures the measurement resource and obtains the measurement result of the second target. The second terminal device can adjust the filtering coefficient to filter the second target measurement result. Similarly, if the second terminal device measures the measurement resource and obtains the measurement result of the first target at time T3, the filtering coefficient used by the second terminal device during filtering can be the same as the filtering coefficient used for filtering the measurement result at time T1. If the second terminal device measures the measurement resource and obtains the measurement result of the second target at time T4, the filtering coefficient used by the second terminal device during filtering can be the same as or different from the filtering coefficient used for filtering the measurement result at time T2. The second terminal device can adjust the filtering coefficient according to the value of the second target measurement result.
[0168] It should be understood that the filtering coefficients for filtering the measurement results of the first target and the filtering coefficients for filtering the measurement results of the second target in the embodiments of this application may be indicated by the second network device, or may be specified by the protocol, or may be determined by the second terminal device itself. This application does not make any specific limitations.
[0169] The communication method of the embodiments of this application has been introduced above. The communication device of the embodiments of this application will be introduced below. The method and device are based on the same technical concept. Since the principle of solving the problem by the method and device is similar, the implementation of the device and method can refer to each other, and the repeated parts will not be described again.
