Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method and device. Background Art

[0002] In wireless communication technology, the transmitter can use detected wireless channel information to assist in transmission. Wireless channel information can be acquired in a variety of ways, but regardless of the method used, the transmitter or receiver must measure specific reference signals to estimate the characteristics of the wireless channel. This process of estimating wireless channel characteristics is called channel sounding. For downlink and uplink channels, there are two types of channel sounding: downlink channel sounding and uplink channel sounding, respectively.

[0003] The current method for disabling downlink channel detection is not flexible enough and cannot meet the needs of terminal devices for flexibly adjusting the channel detection method. Summary of the Invention

[0004] Embodiments of the present application provide a communication method and apparatus for more flexibly disabling downlink channel detection.

[0005] In a first aspect, a communication method is provided. The method may be performed by a first communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the first communication device is a terminal device, or a chip provided in the terminal device for implementing the functions of the terminal device, or other component for implementing the functions of the terminal device. The following description uses the example of the first communication device being a terminal device.

[0006] The method includes: a terminal device may receive first information, the first information being used to disable measurement of channel state information; and / or the first information being used to disable reporting of channel state information. The terminal device does not report the channel state information to a network device.

[0007] Using the above method, the network device can instruct the terminal device to disable the reporting of channel state information through the first information, thereby improving the flexibility of disabling CSI reporting.

[0008] In one possible design, when the first information is used to disable measurement of channel state information, the terminal device may not measure the channel state information. This design can flexibly control the terminal device to disable measurement of channel state information, thereby flexibly adjusting the power consumption of the terminal device.

[0009] In one possible design, the terminal device may stop measuring the channel state information according to the first channel state information resource configuration, and stop reporting the channel state information according to the first channel state information reporting configuration. After a first time period has passed since receiving the first information, the terminal device may measure the channel state information according to the first channel state information resource configuration, and report the channel state information to the network device according to the first channel state information reporting configuration. Thus, the terminal device can resume the measurement and reporting of the channel state information according to the first time period, and before resuming the measurement and reporting, the network device does not need to configure a new channel state information resource configuration and channel state information reporting configuration, and the corresponding configuration before suspending the measurement and reporting is used, saving signaling overhead.

[0010] In one possible design, the terminal device may stop reporting channel state information according to a first channel state information reporting configuration. After a first duration has elapsed after receiving the first information, the terminal device reports the channel state information to the network device according to the first channel state information reporting configuration. Thus, the terminal device may resume reporting channel state information according to the first duration, and before resuming reporting, the network device does not need to configure a new channel state information reporting configuration. The corresponding configuration before suspending reporting is retained, thereby saving signaling overhead.

[0011] In one possible design, the terminal device receives second information, the second information being used to indicate multiple durations, and the first information being used to indicate the first duration from the multiple durations, thereby enabling flexible setting of the first duration.

[0012] In one possible design, the terminal device receives third information indicating multiple durations; the terminal device determines the first duration from the multiple durations based on the terminal device's moving speed and / or the terminal device's mobility state. Thus, flexible setting of the first duration is possible.

[0013] In one possible design, the terminal device stops measuring the channel state information according to the first channel state information resource configuration, and stops reporting the channel state information according to the first channel state information reporting configuration. After receiving the fourth information, the terminal device measures the channel state information according to the first channel state information resource configuration, and reports the channel state information to the network device according to the first channel state information reporting configuration. The fourth information is used to enable channel state information measurement and / or reporting. Thus, the terminal device can resume the measurement and reporting of the channel state information according to the instructions of the network device, and before resuming the measurement and reporting, the network device does not need to configure a new channel state information resource configuration and channel state information reporting configuration. The corresponding configuration before suspending the measurement and reporting is used, saving signaling overhead.

[0014] In one possible design, the terminal device stops reporting channel state information according to the first channel state information reporting configuration. After receiving the fifth information, the terminal device reports the channel state information to the network device according to the first channel state information reporting configuration, and the fifth information is used to enable channel state information measurement and / or reporting. Thus, the terminal device can resume reporting channel state information according to the instructions of the network device, and before resuming reporting, the network device does not need to configure a new channel state information reporting configuration. The corresponding configuration before suspending reporting is used, saving signaling overhead.

[0015] In one possible design, the terminal device stops measuring channel state information according to the first channel state information resource configuration, and stops reporting channel state information according to the first channel state information reporting configuration. In addition, the terminal device may delete the first channel state information resource configuration and / or the first channel state information reporting configuration. Thus, the terminal device may stop measuring and reporting channel state information according to the first information, and delete the corresponding measurement configuration and reporting configuration, thereby stopping downlink channel sounding to save power consumption.

[0016] In one possible design, the terminal device stops reporting channel state information according to the first channel state information reporting configuration and deletes the first channel state information reporting configuration. Thus, the terminal device can stop reporting channel state information according to the first information and delete the corresponding reporting configuration, thereby stopping reporting downlink channel sounding results to save power consumption.

[0017] In one possible design, the first information includes information for deleting the first channel state information resource configuration and / or the first channel state information reporting configuration. Therefore, the terminal device may delete the corresponding configuration only when the first information indicates that the first channel state information resource configuration and / or the first channel state information reporting configuration need to be deleted, and may not delete the corresponding configuration otherwise, thereby providing a more flexible implementation.

[0018] In one possible design, the first channel state information resource configuration includes one or more channel state information resource configurations of the terminal device, and the first channel state information reporting configuration includes one or more channel state information reporting configurations of the terminal device. This design enables the network device to flexibly control the terminal device to stop measuring according to one or more resource configurations, and flexibly control the terminal device to stop reporting channel state information according to one or more reporting configurations.

[0019] In one possible design, the terminal device is configured with multiple channel state information resource configurations, the first information is used to disable measurement of channel state information according to the first channel state information resource configuration, and the multiple channel state information resource configurations include the first channel state information resource configuration; and / or the terminal device is configured with multiple channel state information reporting configurations, the first information is used to disable reporting of channel state information according to the first channel state information reporting configuration, and the multiple channel state information reporting configurations include the first channel state information reporting configuration. This design allows the network device to flexibly indicate the first channel state information resource configuration and / or the first channel state information reporting configuration.

[0020] In one possible design, the channel state information includes at least one of periodic channel state information, semi-persistent channel state information, or aperiodic channel state information. This design enables flexible transmission of the first information and is therefore applicable to periodic, semi-persistent, and aperiodic CSI measurement, CSI reporting, and SRS measurement.

[0021] In a second aspect, a communication method is provided.

[0033] Using the above method, the network device can indicate multiple periods to the terminal device, and can dynamically indicate the resource period of the channel state information used for CSI measurement reporting and / or the reporting period of the channel state information through the seventh information. Therefore, the period of the channel state information can be flexibly adjusted according to the channel conditions and the status of the terminal device itself to save power consumption.

[0034] In one possible design, the sixth information is used to indicate multiple periods, the seventh information includes an identifier of the first period, and the multiple periods include the first period; or, the seventh information is used by the terminal device to determine the first period from the multiple periods based on a second period, and the second period is the period of the channel state information resources used by the terminal device before receiving the seventh information, or, the second period is the reporting period of the channel state information used by the terminal device before receiving the seventh information. Therefore, the terminal device can determine the first period from the multiple periods based on the second period, thereby determining the period of the updated channel state information resources according to the indication of the network device or according to the period of the channel state information resources previously adopted by itself, or determining the reporting period of the updated channel state information according to the indication of the network device or according to the reporting period of the channel state information previously adopted by itself, thereby achieving flexible and accurate determination of the channel state information period and improving energy saving effects.

[0154] In order to make the purpose, technical solutions and advantages of this application more clear, the application will be further described in detail below with reference to the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments.

[0155] like Figure 1 As shown, the measurement feedback method provided in the embodiment of the present application can be applied to a wireless communication system, which may include a terminal device 101 and a network device 102.

[0156] It should be understood that the above wireless communication system is applicable to both low-frequency scenarios (sub 6G) and high-frequency scenarios (above 6G). Application scenarios of wireless communication systems include but are not limited to fifth-generation systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0157] The terminal device 101 shown above may be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent, or terminal device, etc. The terminal device 101 may have wireless transceiver functions, and may communicate (e.g., wirelessly) with one or more network devices of one or more communication systems and receive network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0158] Among them, the terminal device 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc.

[0159] In addition, the terminal device 101 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; the terminal device 101 can also be deployed on the water (such as a ship); the terminal device 101 can also be deployed in the air (such as an airplane, a balloon, and a satellite). The terminal device 101 can specifically be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The terminal device 101 can also be a communication chip with a communication module, or a vehicle with communication function, or an on-board device (such as an on-board communication device, an on-board communication chip), etc.

[0160] The network device 102 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. The network device 102 may specifically include a base station (BS), or a base station and a radio resource management device for controlling the base station. The network device 102 may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station. The network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

[0161] For example, the network device 102 includes, but is not limited to, a next-generation base station (g nodeB, gNB) in 5G, an evolved node B (eNB) in an LTE system, a radio network controller (RNC), a wireless controller under a CRAN system, a base station controller (BSC), a home base station (e.g., home evolved nodeB, or home nodeB, HNB), a baseband unit (BBU), a transmission point (TRP), a transmitting point (TP), or a mobile switching center, etc. The network device 102 may also include a base station in a future 6G or newer mobile communication system.

[0162] In addition, if Figure 2a As shown, in the embodiment of the present application, the network device can also transmit data or control signaling to a single or multiple terminal devices, or as shown in FIG. Figure 2b As shown, multiple network devices can transmit data or control signaling to a single terminal device. Figure 2a or Figure 2b For the description of the terminal device and the network device shown, reference can be made to the description of the terminal device 101 and the network device 102 mentioned above.

[0163] Below Figure 1 The system shown is taken as an example to illustrate the channel detection method in the prior art.

[0164] Typical downlink channel detection is based on the downlink channel state information reference signal (CSI-RS), that is, the terminal device 101 measures the CSI-RS signal sent by the network device 102 according to the CSI resource configuration sent by the network device 102 to obtain the downlink channel characteristics, and the terminal device 101 reports the downlink channel characteristics to the network device 102 according to the CSI report configuration sent by the network device 102.

[0165] CSI-RS resources can be divided into three types according to their time domain characteristics, namely periodic, semi-persistent (SP) and aperiodic.

[0166] For periodic CSI-RS resources, the terminal device 101 believes that the transmission of CSI-RS will be repeated every N time units (time unit i). The following explanation is based on the time unit being a time slot (slot). Among them, the minimum value of N can be 4, that is, the network device 102 sends a CSI-RS once every 4 time slots. The maximum value of N can be 640, that is, the network device 102 sends a CSI-RS once every 640 time slots. In addition to the period, the terminal device 101 also needs to know a specific offset (offset) to find the time domain position of the CSI-RS. Taking the offset as a time slot offset (slot offset) as an example, in order to determine the time domain position of the CSI-RS, the terminal device 101 needs to know how many time slots the CSI-RS transmission moment is offset within a period.

[0167] For the CSI-RS resources of the SP, the network device 102 will configure the transmission period and offset of the CSI-RS of the SP. In addition, the semi-continuously transmitted CSI-RS is controlled by the media access control (MAC) control element (MAC CE) related to the activation / deactivation of the SP CSI resource set, that is, the MAC CE can activate / deactivate the transmission of the CSI-RS resources of the SP. After the network device 102 activates the CSI-RS resources of the SP through the MAC CE, the terminal device 101 will believe that the CSI-RS resources of the SP are periodically transmitted according to the configured parameters until it is deactivated by the MAC CE. After the network device 102 deactivates the CSI-RS resources of the SP through the MAC CE, the terminal device 101 will believe that the network device 102 no longer transmits the CSI-RS resources of the SP.

[0168] For aperiodic CSI-RS, network device 102 does not configure the CSI-RS transmission period or offset. Network device 102 triggers the transmission of CSI-RS resources through downlink control information (DCI). That is, network device 102 notifies the UE through DCI before each CSI-RS resource transmission.

[0169] The terminal device 101 can perform different CSI measurements based on the configuration of the network device 102. For most measurements, the terminal device 101 needs to report the measurement results to the network device 102. In this case, the network device 102 configures how the UE sends CSI reports through the CSI reporting configuration.

[0170] Similar to the time domain characteristics of CSI-RS resources, CSI reporting can be divided into periodic reporting, semi-continuous reporting and aperiodic reporting.

[0171] For periodic CSI reporting, the network device 102 needs to configure a certain reporting period for the terminal device 101. The periodic reporting is carried by the physical uplink control channel (PUCCH), that is, the periodic CSI report is sent on the PUCCH.

[0172] For SP CSI reporting, network device 102 configures a specific reporting period. Furthermore, SP CSI reporting is controlled by the MAC CE or DCI related to SP CSI reporting activation / deactivation. When network device 102 activates SP CSI reporting via a MAC CE, terminal device 101 sends a CSI report on the PUCCH. When network device 102 triggers SP CSI reporting via a DCI, terminal device 101 sends a CSI report on the physical uplink shared channel (PUSCH).

[0173] For aperiodic CSI reporting, network device 102 triggers aperiodic CSI reporting via DCI, more precisely, via the CSI-request field in the DCI. Aperiodic reporting is carried over the physical uplink shared channel (PUSCH), meaning that aperiodic CSI reports are sent on the PUSCH.

[0174] The report quantity in the CSI report includes but is not limited to the following: channel quality indicator (CQI), used to indicate the coding and modulation method recommended by the terminal device 101. Precoding matrix indicator (PMI), used to indicate the best precoding matrix recommended by the terminal device 101. CSI reference signal resource indicator (CSI-RS resource indicator, CRI). SSB resource indicator (SS / PBCH block resource indicator, SSBRI). Layer indicator (LI), used to indicate the strongest layer. Rank indicator (RI), used to indicate the best number of layers for downlink transmission recommended by the terminal device 101. Layer 1 reference signal received power (L1-RSRP). Among them, the report quantity carried in the CSI report is determined according to the CSI reporting configuration.

[0175] In this application, CSI resource configuration and / or CSI reporting configuration may be referred to as CSI configuration.

[0176] In the prior art, the network device 102 needs to provide the terminal device 101 with a downlink channel sounding configuration through an RRC reconfiguration message to activate the downlink channel sounding; or, in addition to providing a set of downlink channel sounding configurations through an RRC reconfiguration message, the network device also needs to indicate the activation of the channel sounding configuration through separate signaling, so that the terminal device 101 implements CSI-RS-based downlink channel sounding according to the downlink channel sounding configuration. When the network device wants the terminal device 101 to stop executing a certain downlink channel sounding configuration, the network device 102 also needs to indicate the terminal device 101 to delete the downlink channel sounding configuration through an RRC reconfiguration message, or the network device needs to indicate the deactivation of the downlink channel sounding configuration through separate signaling.

[0177] Therefore, the current start (or enabling) or stop (or disabling) of downlink channel detection of terminal devices depends on the activation and deactivation of the downlink channel detection configuration by the network device. Therefore, the enabling and disabling methods of downlink channel detection are not flexible enough and cannot meet the demand for flexible control of whether the terminal device performs downlink channel detection.

[0178] In order to optimize the enabling and disabling scheme of downlink channel detection, an embodiment of the present application provides a communication method. The communication method can be executed by a terminal device and a network device. The terminal device includes Figure 1The terminal device 101 shown in FIG. 1 , the network device may include the network device 102 shown in FIG. 1 .

[0179] like Figure 3 As shown, the communication method may include the following steps:

[0180] S101: A network device sends first information to a terminal device. The first information is used to disable CSI measurement; and / or the first information is used to disable CSI reporting.

[0181] Correspondingly, the terminal device receives the first information.

[0182] S102: The terminal device does not send a CSI report to the network device.

[0183] It should be understood that reporting CSI (or reporting CSI) in this application includes the terminal device sending a CSI report to the network device. Subsequently, reporting CSI or reporting CSI can be used to indicate that the terminal device sends a CSI report to the network device.

[0184] Accordingly, the network device does not receive the CSI report from the terminal device.

[0185] Optionally, if the first information instructs the terminal device to disable CSI measurement, or instructs the terminal device to disable CSI measurement and CSI reporting, the terminal device does not measure CSI after receiving the first information, and does not send CSI to the network device. If the first information instructs the terminal device to disable CSI reporting, the terminal device does not send CSI to the network device, but the terminal device may or may not measure CSI.

[0186] By adopting the above method, the network device can instruct the terminal device to disable CSI reporting through the first information, thereby improving the flexibility of disabling CSI reporting.

[0187] Similarly, in the above process, the first information can also be replaced by information used to indicate enabling CSI measurement and / or enabling CSI reporting, and the terminal device performs CSI reporting after receiving the first information to improve the flexibility of enabling CSI reporting.

[0188] Optionally, the above CSI includes at least one of periodic channel state information, semi-persistent channel state information, or aperiodic channel state information. That is, the above solution can be applied during the configuration process of periodic channel state information, semi-persistent channel state information, or aperiodic channel state information.

[0189] Exemplarily, the above first information may be carried in an RRC message, MAC CE or DCI.

[0190] Optionally, after S102, the terminal device may resume the execution of CSI measurement and reporting according to the first duration or according to the instruction of the network device to enable CSI measurement and / or reporting more flexibly.

[0191] In S102, when the terminal device stops measuring CSI according to the first CSI resource configuration and stops reporting CSI according to the first CSI reporting configuration, the terminal device may measure CSI according to the first CSI resource configuration after a first time period after receiving the first information, and report CSI to the network device according to the first CSI reporting configuration to resume CSI measurement and reporting.

[0192] In this example, the CSI measurement and reporting of the terminal device can be suspended (or temporarily disabled) to control the terminal device to enable and disable the CSI more flexibly. Furthermore, when suspending CSI measurement and reporting, there is no need to delete the CSI measurement configuration and CSI reporting configuration, nor is there any need to reconfigure the CSI measurement configuration and CSI reporting configuration before resuming CSI reporting. After CSI measurement and reporting are resumed, CSI measurement and reporting are still performed according to the CSI configuration before suspension, thereby saving overhead.

[0193] Optionally, the first duration is preconfigured, and the network device is configured with the same first duration for resuming reception of CSI from the terminal device after the first duration has elapsed after the terminal device receives the first information (or the network device sends the first information). For example, the first duration is preconfigured to a set value.

[0194] Optionally, the first duration may be indicated by the network device. For example, the first information may include the first duration or information indicating the first duration. For example, the network device may further send second information to the terminal device, where the second information may be used to indicate multiple durations. Additionally, the network device may send first information to the terminal device, where the first information includes information indicating the first duration, which is used to indicate the first duration from the multiple durations.

[0195] The second information and the first information may be carried in different information elements (IEs) in the same message, or the first information and the second information may be carried in different signaling.

[0196] Optionally, the first duration may also be determined according to the moving speed and / or mobility state of the terminal device.

[0197] One feasible implementation method is that the network device may send third information to the terminal device, and the third information may be used to indicate multiple durations. Thereafter, the terminal device may determine the first duration from the multiple durations based on its own moving speed and / or mobility status.

[0198] There is a one-to-one correspondence between the terminal device's movement speed and / or mobility state and multiple durations. The terminal device may determine the first duration corresponding to its own movement speed and / or mobility state based on a first correspondence relationship. The first correspondence relationship is a correspondence relationship between multiple durations and multiple movement speeds and / or mobility states. The multiple durations included in the first correspondence relationship may include multiple durations indicated by third information, and the multiple durations indicated by the third information include the first duration. The first correspondence relationship is preconfigured.

[0199] Alternatively, the network device may send the first correspondence to the terminal device. For example, the third information is used to indicate the first correspondence, i.e., to indicate the correspondence between multiple durations and multiple movement speeds and / or mobility states. The first correspondence may be indicated by a mapping table, etc., and is not specifically limited in this application.

[0200] An example of the above first correspondence is shown in Table 1.

[0201] Moving speed (m / min) Mobility Status Duration (seconds) ≤20 - 20 20＜X≤200 - 10 X＞200 - 5 - High mobility 15 - Low mobility 25

[0202] Table 1

[0203] Table 1 above is merely illustrative. In actual use, the correspondence between multiple moving speeds and multiple durations can be used as a mapping table, and / or the correspondence between multiple mobility states and multiple durations can be used as a mapping table. This application does not specifically limit this. In addition, the settings of moving speeds, mobility states, and durations in Table 1 are merely illustrative examples and should not be construed as limiting.

[0204] Similarly, in S102, when the terminal device stops reporting CSI according to the first CSI reporting configuration, the terminal device may resume reporting CSI to the network device according to the first CSI reporting configuration after a first period of time has passed since receiving the first information. At this point, the terminal device may continue to perform CSI measurements but does not need to report CSI.

[0205] This allows the suspension of CSI reporting by terminal devices (or temporary disabling of CSI reporting) to more flexibly enable and disable CSI reporting. Furthermore, there's no need to delete the CSI reporting configuration when suspending CSI reporting, nor is there a need to reconfigure the CSI reporting configuration before resuming CSI reporting. After CSI reporting resumes, CSI measurement and reporting continues based on the pre-pause CSI configuration, saving overhead.

[0206] The method for determining the first duration can refer to the above description and will not be repeated here.

[0207] In addition, after S102, the network device may further send fourth information to the terminal device, where the fourth information may be used to enable CSI measurement and / or reporting. The fourth information may correspond to the first information. For example, if the first information is used to disable CSI measurement, the fourth information may be used to enable CSI measurement; and if the first information is used to disable CSI measurement and CSI reporting, the fourth information may be used to enable CSI measurement and reporting.

[0208] The fourth information may be carried in an RRC message, a MAC CE or a DCI.

[0209] Specifically, when the terminal device stops measuring CSI according to the first CSI resource configuration and stops reporting CSI according to the first CSI reporting configuration, the terminal device may resume measuring CSI according to the first CSI resource configuration after receiving the fourth information, and report CSI to the network device according to the first CSI reporting configuration to resume CSI measurement and reporting.

[0210] In this example, the CSI measurement and reporting of the terminal device can be suspended (or temporarily disabled) to control the terminal device to enable and disable the CSI more flexibly. Furthermore, when suspending CSI measurement and reporting, there is no need to delete the CSI measurement configuration and CSI reporting configuration, nor is there any need to reconfigure the CSI measurement configuration and CSI reporting configuration before resuming CSI reporting. After CSI measurement and reporting are resumed, CSI measurement and reporting are still performed according to the CSI configuration before suspension, thereby saving overhead.

[0211] Similarly, in S102, when the terminal device stops reporting CSI according to the first CSI reporting configuration, the terminal device may continue to perform CSI measurements, but no longer perform CSI reporting. After receiving the fifth information, the terminal device may resume reporting CSI to the network device according to the first CSI reporting configuration, and there is no need to reconfigure the CSI measurement configuration and the CSI reporting configuration before resuming CSI reporting. Alternatively, when the terminal device stops reporting CSI according to the first CSI reporting configuration, the terminal device may stop performing CSI measurements according to the first CSI resource configuration, and after receiving the fifth information, the terminal device may resume performing CSI measurements according to the first CSI resource configuration, and resume reporting CSI according to the first CSI reporting configuration, and there is no need to reconfigure the CSI measurement configuration and the CSI reporting configuration before resuming CSI reporting.

[0212] The fifth information may be carried in an RRC message, a MAC CE or a DCI.

[0213] This allows the suspension of CSI reporting by terminal devices (or temporary disabling of CSI reporting) to more flexibly enable and disable CSI reporting. Furthermore, there's no need to delete the CSI reporting configuration when suspending CSI reporting, nor is there a need to reconfigure the CSI reporting configuration before resuming CSI reporting. After CSI reporting resumes, CSI measurement and reporting continues based on the pre-pause CSI configuration, saving overhead.

[0214] Optionally, after the terminal device stops reporting CSI in S102, it may delete the CSI resource configuration and / or CSI reporting configuration, or delete the CSI resource configuration and / or CSI reporting configuration only when the first information is also used to delete the CSI resource configuration and / or CSI reporting configuration, or only when the first information does not indicate that the CSI configuration is to be retained.

[0215] The CSI measurement configuration and / or CSI reporting configuration deleted by the terminal device here includes, but is not limited to, the CSI resource configuration used before receiving the first information and / or the CSI reporting configuration used before receiving the first information. For example, the terminal device may delete all CSI resource configurations and CSI reporting configurations, thereby stopping CSI measurement and reporting to save power consumption.

[0216] For example, when the terminal device stops measuring CSI according to the first CSI resource configuration and stops reporting CSI according to the first CSI reporting configuration, the terminal device may also delete the first CSI resource configuration, i.e., the CSI resource configuration used before receiving the first information, and delete the first CSI reporting configuration, i.e., the CSI reporting configuration used before receiving the first information. If the terminal device subsequently needs to resume CSI measurement and reporting, the network device will need to resend the CSI resource configuration and CSI reporting configuration.

[0217] Similarly, when the terminal device stops reporting CSI according to the first CSI reporting configuration, the terminal device may also delete the first CSI reporting configuration.

[0218] In the above example, the first information may indicate the first CSI resource configuration from multiple CSI resource configurations of the terminal device, for example, the first information includes an identifier of the first CSI resource configuration to indicate the first CSI resource configuration. Alternatively, the first information may be used to indicate disabling of CSI measurement according to the first CSI resource configuration. The first information may also indicate the first CSI reporting configuration from multiple CSI reporting configurations of the terminal device, for example, the first information includes an identifier of the first CSI reporting configuration to indicate the first CSI reporting configuration. Alternatively, the first information may be used to indicate disabling of reporting of channel state information according to the first CSI reporting.

[0219] It should be understood that the first CSI resource configuration herein may include one or more CSI resource configurations of the terminal device, and the first CSI reporting configuration may include one or more CSI reporting configurations of the terminal device. The terminal device may currently be using multiple CSI resource configurations, and the first CSI resource configuration may be part or all of the multiple resource configurations. Furthermore, the terminal device may currently be using multiple CSI reporting configurations, and the first CSI resource configuration may be part or all of the multiple reporting configurations.

[0220] like Figure 4 As shown, the embodiment of the present application provides another communication method for flexibly configuring the CSI period of periodic CSI. It should be understood that the CSI period here includes the CSI resource period and / or the CSI reporting period. The method may include the following steps:

[0221] S201: The network device sends the sixth information to the terminal device. The sixth information may be indicated for at least one period.

[0222] Correspondingly, the terminal device receives the sixth information.

[0223] S202: The network device sends seventh information to the terminal device. The seventh information is used to indicate that the first period in at least one period is a CSI resource period and / or a CSI reporting period. In other words, the seventh information is used to indicate the first period in at least one period, and the terminal device uses the first period as a CSI resource period and / or a CSI reporting period.

[0224] Among them, the seventh information can be carried in the RRC message, MAC CE or DCI.

[0225] Correspondingly, the terminal device receives the seventh information.

[0226] Using the above method, the network device can indicate multiple periods to the terminal device, and can dynamically indicate the CSI resource period and / or CSI reporting period used for CSI measurement reporting through the seventh information. Therefore, the CSI period can be flexibly adjusted according to the channel conditions and the status of the terminal device itself to save power consumption.

[0227] Optionally, the sixth information may indicate multiple cycles, and the seventh information is used to indicate the first cycle from the multiple cycles. For example, the seventh information may include an identifier (or index, number) of the first cycle.

[0228] For example, the seventh information may include an identifier of the first period among multiple periods. For example, if the sixth information indicates that the multiple periods are 5s, 10s, 15s, and 20s, and the identifiers indicating the multiple periods are 1, 2, 3, and 4, respectively, then when the seventh information carries the identifier 1, it indicates that the first period is 5s.

[0229] Optionally, the seventh information can be used by the terminal device to determine the first period from multiple periods indicated by the sixth information based on the second period, wherein the second period is the CSI resource period and / or CSI reporting period adopted by the terminal device before receiving the sixth information.

[0230] For example, when the terminal device receives the seventh information, when the seventh information is used to instruct the terminal device to increase the CSI resource period (and / or CSI reporting period), if the multiple periods indicated by the sixth information are 5s, 10s, 15s and 20s, and the CSI resource period (and / or CSI reporting period) used by the terminal device before receiving the seventh information is 12s, then after receiving the seventh information, the terminal device may adjust the CSI resource period (and / or CSI reporting period) to 15s (or 20s). Alternatively, when the terminal device is used to instruct the terminal device to reduce the CSI resource period (and / or CSI reporting period), if the multiple periods indicated by the sixth information are 5s, 10s, 15s and 20s, and the CSI resource period (and / or CSI reporting period) used by the terminal device before receiving the seventh information is 12s, then after receiving the seventh information, the terminal device may adjust the CSI resource period (and / or CSI reporting period) to 10s (or 5s).

[0231] Among them, the seventh period may carry an indication for instructing the terminal device to increase or decrease the CSI period, for example, it carries a bit. When the bit position is 0, the seventh information is used to instruct the terminal device to increase the CSI period, that is, select a first period larger than the second period from multiple periods (for example, the first period is the smallest period among at least one period larger than the second period in multiple periods); when the bit position is 1, the seventh information is used to instruct the terminal device to reduce the CSI period, that is, select a first period smaller than the second period from multiple periods (for example, the first period is the largest period among at least one period smaller than the second period in multiple periods). Similarly, the seventh information may also instruct the terminal device to increase the CSI period when the bit is set to 1, or may instruct the terminal device to increase the CSI period when the bit is set to 0.

[0232] Optionally, when the first period is a specific period, the terminal device does not perform periodic CSI measurement and / or periodic CSI reporting. The first period may be a set value, and when the terminal device and the network device adopt the first period by default, periodic CSI measurement and / or CSI reporting are stopped. For example, the length of the first period is 0, or the identifier of the first period is a specific identifier, such as identifier 0.

[0233] Accordingly, when the first period is a specific period, the network device does not receive a CSI report from the terminal device. If multiple terminal devices served by the network device are all in a non-CSI transmission state, for example, the network device configures the CSI measurement period and / or CSI reporting period for its multiple associated terminal devices to be the specific period, the network device may not transmit CSI resources, or in other words, the network device may not transmit CSI-RS. The CSI resources are used by the terminal devices associated with the network device to determine CSI.

[0234] like Figure 5 As shown, the embodiment of the present application provides another communication method for flexibly configuring the CSI period of periodic CSI. It should be understood that the CSI period here includes the CSI resource period and / or the CSI reporting period. The method may include the following steps:

[0235] S301: The network device sends eighth information to the terminal device, where the eighth information is used to determine a first adjustment amount.

[0236] The eighth information may be carried in an RRC message, a MAC CE or a DCI.

[0237] Accordingly, the terminal device receives the eighth information.

[0238] S302: The terminal device determines an updated CSI resource period according to the CSI resource period in use and the first adjustment amount, and / or the terminal device determines an updated CSI reporting period according to the CSI reporting period in use and the first adjustment amount.

[0239] By adopting the above method, when adjusting the CSI period configuration, the terminal device only needs to indicate the adjustment amount, and does not need to reconfigure the CSI period, thereby saving overhead and being able to flexibly adjust the CSI period to save power consumption of the terminal device.

[0240] Optionally, the eighth information may be used to indicate the first adjustment amount. For example, the eighth information may instruct the terminal device to increase the CSI resource period by 5s.

[0241] Optionally, the eighth information may be used to indicate a second correspondence, which is a correspondence between a moving speed and / or a mobility state and an adjustment amount. Therefore, the terminal device may determine a first adjustment amount corresponding thereto based on its own moving speed and / or mobility state.

[0242] The second corresponding relationship is shown in Table 2, for example.

[0243] Moving speed (m / min) Mobility Status Adjustment amount(s) ≤20 - +5 20＜X≤200 - -5 X＞200 - -10 - High mobility -5 - Low mobility +5

[0244] Table 2

[0245] Table 2 above is merely illustrative. In actual use, the correspondence between multiple moving speeds and multiple durations can be used as a mapping table, and / or the correspondence between multiple mobility states and multiple durations can be used as a mapping table. This application does not impose any specific limitations. In addition, the settings of moving speeds, mobility states, and durations in Table 2 are merely illustrative examples and should not be construed as limiting.

[0246] As shown in Table 2, when the moving speed of the terminal device is less than 20m / min, the terminal device can increase the CSI resource period and / or CSI reporting period by 5s, so the CSI measurement and / or reporting period can be appropriately extended to reduce power consumption.

[0247] The following describes the communication device used to implement the above method in the embodiment of the present application with reference to the accompanying drawings. Therefore, the above contents can be used in subsequent embodiments, and repeated contents will not be repeated.

[0248] Figure 6 Schematic block diagram of a communication device provided in an embodiment of the present application. For example, the communication device is Figure 6 The terminal device 600 is shown.

[0249] The terminal device 600 includes a processing module 610 and a transceiver module 620. Exemplarily, the terminal device 600 may be a network device, or a chip used in a terminal device, or other combined devices, components, etc. having the above-mentioned terminal device functions. When the terminal device 600 is a terminal device, the transceiver module 620 may be a transceiver, which may include an antenna and a radio frequency circuit, etc., and the processing module 610 may be a processor, such as a baseband processor, which may include one or more central processing units (CPUs). When the terminal device 600 is a component having the above-mentioned terminal device functions, the transceiver module 620 may be a radio frequency unit, and the processing module 610 may be a processor, such as a baseband processor.

It should be understood that the processing module 610 in the embodiments of the present application may be implemented by a processor or processor-related circuit components, and the transceiver module 620 may be implemented by a transceiver or transceiver-related circuit components.

[0250] For example, the processing module 610 may be used to perform Figures 3 to 5All operations except the transceiver operations performed by the terminal device in any of the illustrated embodiments, such as S102 and S302, and / or other processes for supporting the technology described herein, such as generating messages, information and / or signaling sent by the transceiver module 620, and processing messages, information and / or signaling received by the transceiver module 620, and further such as Figure 4 In the process shown, the first period is determined to be a CSI resource period and / or a CSI reporting period according to the sixth information and the seventh information. The transceiver module 620 can be used to perform Figures 3 to 5 All receiving and sending operations performed by the terminal device in any of the illustrated embodiments, such as S101, S201, S202 and S301, and / or other processes used to support the technology described in this document, such as sending a CSI report according to the CSI reporting configuration, or not sending a CSI report.

[0251] In addition, the transceiver module 620 may be a functional module that can perform both sending and receiving operations. For example, the transceiver module 620 may be used to perform Figures 3 to 5 In any of the embodiments shown, all sending operations and receiving operations performed by the terminal device, for example, when performing a sending operation, the transceiver module 620 can be considered as a sending module, and when performing a receiving operation, the transceiver module 620 can be considered as a receiving module; or, the transceiver module 620 can also be two functional modules, and the transceiver module 620 can be regarded as a general term for the two functional modules, which are a sending module and a receiving module, respectively. The sending module is used to complete the sending operation, for example, the sending module can be used to perform Figures 3 to 5 In any of the embodiments shown, the receiving module is used to perform all the sending operations performed by the terminal device, for example, the receiving module can be used to perform Figures 3 to 5 All receiving operations performed by the terminal device in any embodiment.

[0252] Among them, in the implementation Figure 3 In the method shown, the transceiver module 620 may receive first information for disabling measurement of channel state information and / or disabling reporting of channel state information. The transceiver module 620 does not report the channel state information to the network device.

[0253] In one possible design, when the first information is used to disable the measurement of channel state information, the processing module 610 does not measure the channel state information.

[0254] In one possible design, the processing module 610 may stop measuring channel state information according to the first channel state information resource configuration, and the transceiver module 620 may stop reporting channel state information according to the first channel state information reporting configuration. After a first time period has elapsed after receiving the first information, the processing module 610 may measure channel state information according to the first channel state information resource configuration, and the transceiver module 620 may report the channel state information to the network device according to the first channel state information reporting configuration.

[0255] In one possible design, the transceiver module 620 may stop reporting the channel state information according to the first channel state information reporting configuration. After a first time period has passed after receiving the first information, the transceiver module 620 reports the channel state information to the network device according to the first channel state information reporting configuration.

[0256] In one possible design, the transceiver module 620 receives second information, where the second information is used to indicate multiple durations, and the first information is also used to indicate the first duration from the multiple durations.

[0257] In one possible design, the transceiver module 620 receives third information, where the third information is used to indicate multiple durations; the processing module 610 determines the first duration from the multiple durations based on the moving speed of the terminal device and / or the mobility status of the terminal device.

[0258] In one possible design, the processing module 610 stops measuring channel state information according to the first channel state information resource configuration, and the transceiver module 620 stops reporting channel state information according to the first channel state information reporting configuration. After receiving fourth information, the processing module 610 measures channel state information according to the first channel state information resource configuration, and the transceiver module 620 reports channel state information to the network device according to the first channel state information reporting configuration. The fourth information is used to enable channel state information measurement and / or reporting.

[0259] In one possible design, the transceiver module 620 stops reporting channel state information according to the first channel state information reporting configuration. After receiving the fifth information, the transceiver module 620 reports the channel state information to the network device according to the first channel state information reporting configuration.

[0266] In executing the above Figure 4 In the method shown, the transceiver module 620 receives sixth information indicating at least one period. The transceiver module 620 also receives seventh information indicating that a first period in the at least one period is a resource period for channel state information; and / or the seventh information indicates that the first period in the at least one period is a reporting period for channel state information.

[0267] In one possible design, the sixth information is used to indicate multiple periods, the seventh information includes an identifier of the first period, and the multiple periods include the first period; or, the seventh information is used by the terminal device to determine the first period from the multiple periods based on a second period, where the second period is a period of channel state information resources used by the terminal device before receiving the seventh information, or the second period is a period for reporting channel state information used by the terminal device before receiving the seventh information. The processing module 610 may determine the first period from the multiple periods based on the second period.

It should be understood that the processing module 710 in the embodiments of the present application may be implemented by a processor or processor-related circuit components, and the transceiver module 720 may be implemented by a transceiver or transceiver-related circuit components.

[0273] For example, the processing module 710 can be used to perform Figure 3 or Figures 5 to 7 All operations performed by the network device in any of the embodiments shown except for the transceiver operations, such as executing S302, generating messages, information and / or signaling sent by the transceiver module 620, and / or processing messages, information and / or signaling received by the transceiver module 720, and / or other processes used to support the technology described herein.

[0274] In addition, the transceiver module 720 may be a functional module that can perform both sending and receiving operations. For example, the transceiver module 720 may be used to perform Figure 3 or Figures 5 to 7 In any embodiment shown, all sending operations and receiving operations performed by the network device, for example, when performing a sending operation, the transceiver module 720 can be considered as a sending module, and when performing a receiving operation, the transceiver module 720 can be considered as a receiving module; or, the transceiver module 720 can also be two functional modules, and the transceiver module 720 can be regarded as a general term for the two functional modules, which are a sending module and a receiving module respectively.

[0277] In one possible design, the transceiver module 620 sends third information to the terminal device, where the third information is used to indicate multiple durations.

[0278] In one possible design, the transceiver module 620 sends fourth information (or fifth information) to the terminal device, where the fourth information (or fifth information) is used to enable channel state information measurement and / or reporting.

[0279] In one possible design, the first information includes information for deleting the first channel state information resource configuration and / or the first channel state information reporting configuration.

[0280] In one possible design, the first channel state information resource configuration includes one or more channel state information resource configurations of the terminal device, and the first channel state information reporting configuration includes one or more channel state information reporting configurations of the terminal device.

[0281] In one possible design, the terminal device is configured with multiple channel state information resource configurations, the first information is used to disable the measurement of channel state information according to the first channel state information resource configuration, and the multiple channel state information resource configurations include the first channel state information resource configuration; and / or, the terminal device is configured with multiple channel state information reporting configurations, the first information is used to disable the reporting of channel state information according to the first channel state information reporting configuration, and the multiple channel state information reporting configurations include the first channel state information reporting configuration.

[0282] In one possible design, the channel state information includes at least one of periodic channel state information, semi-persistent channel state information, or non-periodic channel state information.

[0283] In executing the above Figure 4 When using the method shown, the transceiver module 620 sends sixth information to the terminal device, and the sixth information is used to indicate at least one period; the transceiver module 620 sends seventh information to the terminal device, and the seventh information is used to indicate that the first period in the at least one period is a resource period for channel state information; and / or, the seventh information is used to indicate that the first period in the at least one period is a reporting period for channel state information.

The transceiver module 620 sends the eighth information to the terminal device.

[0287] In one possible design, the eighth information is used to indicate the first adjustment amount.

[0288] In a possible design, the eighth information is used to indicate a second corresponding relationship, where the second corresponding relationship is a corresponding relationship between a moving speed and / or mobility state and an adjustment amount.

[0289] The present application also provides a communication device, which can be a terminal device or a circuit, and can be used to execute the actions executed by the terminal device in the above method embodiment.

[0290] When the communication device is a terminal device, Figure 8The following is a simplified schematic diagram of the terminal device. Figure 8 In this article, the terminal device is a mobile phone. Figure 8 As shown, the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and input and output devices. The processor is mainly used to process communication protocols and communication data, as well as to control the terminal device, execute software programs, process software program data, etc. The memory is mainly used to store software programs and data. The radio frequency circuit is mainly used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is mainly used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, displays, keyboards, etc., are mainly used to receive data input by users and output data to users. It should be noted that some types of terminal devices may not have input and output devices.

[0291] When data needs to be sent, the processor performs baseband processing on the data to be sent and outputs the baseband signal to the RF circuit. The RF circuit performs RF processing on the baseband signal and then transmits the RF signal to the outside in the form of electromagnetic waves through the antenna.
