Abstract
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, channel sounding types include downlink channel sounding and uplink channel sounding, respectively. Downlink channel sounding and uplink channel sounding are performed based on corresponding channel sounding configurations.
[0003] However, the current activation or deactivation method of the channel detection configuration is not flexible enough and cannot meet the requirements of the terminal device 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 implementing activation or deactivation of a channel sounding configuration.
[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 receiving a first configuration and at least one second configuration corresponding to the first configuration, the first configuration including a channel state information configuration and the second configuration including a sounding reference signal configuration; or the first configuration including a sounding reference signal configuration and the second configuration including a channel state information configuration. The terminal device may also receive first information for activating the first configuration. The terminal device may activate the first configuration and a third configuration, the third configuration being one of the at least one second configuration, or the terminal device may activate the first configuration and deactivate the third configuration, the third configuration being one of the at least one second configuration.
[0007] By adopting this method, the terminal device can activate the first configuration after receiving the first information, and activate or deactivate the third configuration at the same time. Therefore, the activation or deactivation of the third configuration no longer depends on the message sent by the network device for activating or deactivating the third configuration. It can improve the flexibility of activation and deactivation of the channel detection configuration and reduce signaling overhead.
[0008] In one possible design, when the first configuration corresponds to multiple second configurations, the first information may further include information about the third configuration. The terminal device may activate the third configuration based on the third configuration information, or deactivate the third configuration based on the third configuration information. This design enables flexible indication of the third configuration.
[0009] In one possible design, when the third configuration includes a specific channel state information configuration, after the third configuration is activated, the terminal device may not perform channel state information measurement and / or may not report the channel state information. In other words, when the third configuration includes the specific channel state information configuration, the terminal device disables channel state information reporting to reduce power consumption and save energy.
[0010] In one possible design, when the first configuration includes a specific channel state information configuration, the terminal device may not perform channel state information measurement and / or may not report the channel state information. In other words, when the first configuration includes the specific channel state information configuration, the terminal device disables channel state information reporting to reduce power consumption and save energy.
[0011] In one possible design, the first information is carried in radio resource control (RRC) signaling (or RRC message), a media access control (MAC) control element (MAC CE), or downlink control information (DCI). This design enables flexible transmission of the first information and is therefore applicable to periodic, semi-persistent, and aperiodic CSI measurements, CSI reporting, and SRS measurements.

Alternatively, the first information may carry indication information such that the terminal device needs to activate the third configuration in addition to activating the first configuration, or the terminal device needs to activate the third configuration in addition to activating the first configuration.
[0015] In one possible design, when the first configuration corresponds to multiple second configurations, the first information may further include information of the third configuration.
[0016] In one possible design, when the third configuration includes a specific channel state information configuration, the network device may also not send CSI resources, where the CSI resources are used to determine the channel state information, and / or not receive a channel state information report from the terminal device.
[0017] Optionally, after determining that the terminal device activates the third configuration, the network device does not send CSI resources and / or does not receive a channel state information report from the terminal device. Determining that the terminal device activates the third configuration is, for example, determining that the terminal device activates the third configuration by default after receiving the first information.

[0187] 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.
[0188] 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.
[0189] 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.
[0190] 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.
[0191] 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.
[0192] 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.
[0193] 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.
[0194] 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.
[0195] 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 aforementioned terminal device 101 and the network device 102 .
[0196] Below Figure 1 The system shown is taken as an example to illustrate the channel detection method in the prior art.
[0197] 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.
[0198] CSI-RS resources can be divided into three types according to their time domain characteristics, namely periodic, semi-persistent (SP) and aperiodic.
[0199] 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.
[0200] 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.
[0201] 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.
[0202] 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.
[0203] 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.
[0204] Similar to the time domain characteristics of CSI-RS resources, CSI reporting can be divided into periodic reporting, semi-continuous reporting and aperiodic reporting.
[0205] 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.
[0206] 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).
[0207] 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.
[0208] 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).
[0209] Uplink channel sounding is generally performed based on uplink sounding reference signal (SRS), that is, the network device 102 sends SRS configuration to the terminal device 101, the terminal device 101 sends SRS according to the SRS configuration, and the network device 102 measures the SRS sent by the UE to obtain uplink channel characteristics.
[0210] SRS is divided into three types, namely periodic, semi-continuous and non-periodic.
[0211] For periodically transmitted SRS, the network device 102 configures the period of the SRS and the offset within the period. The terminal device 102 periodically transmits the SRS to the network device 102 according to the configuration.
[0212] For the SRS transmitted by the SP, network device 102 configures the SRS transmission period and offset. Furthermore, the SRS transmitted by the SP is controlled by the SP SRS activation / deactivation-related MAC CE. This means that the MAC CE can activate / deactivate the transmission of the SP's SRS. After network device 102 activates the SP's SRS via a MAC CE, terminal device 101 periodically transmits the SRS according to the configured parameters until it is deactivated by the MAC CE. After network device 102 deactivates the SP's SRS via a MAC CE, the UE ceases to transmit the SP's SRS.
[0213] For non-periodically transmitted SRS, the network device 102 triggers the transmission of the SRS through DCI, that is, before each SRS needs to be transmitted, the network device 102 notifies the terminal device 101 to transmit the SRS through DCI.
[0214] In this application, CSI resource configuration and / or CSI reporting configuration may be referred to as CSI configuration. CSI configuration and SRS configuration may be referred to as channel sounding configuration.
[0215] In the prior art, the network device 102 needs to provide the terminal device 101 with a channel sounding configuration through a radio resource control (RRC) reconfiguration message (RRC reconfiguration message) to activate the channel sounding; or, in addition to providing a set of channel sounding configurations through the RRC reconfiguration message, the network device also needs to indicate the activation of the channel sounding configuration through a separate signaling, so that the terminal device 101 implements CSI-RS-based downlink channel measurement or SRS-based uplink channel measurement according to the channel sounding configuration. When the network device wants the terminal device 101 to stop executing a certain channel sounding configuration, the network device 102 also needs to indicate the terminal device 101 to delete the channel sounding configuration through the RRC reconfiguration message, or the network device needs to indicate the deactivation of a set of channel sounding configurations through a separate signaling.
[0216] Therefore, the current activation and deactivation scheme of the channel detection configuration relies on RRC messages. Since the RRC message is a high-level signaling, the activation and deactivation method of the channel detection configuration is not flexible enough, and there are problems of high overhead and high latency, which cannot meet the terminal equipment's demand for flexible configuration of channel detection.
[0217] In order to optimize the activation and deactivation scheme of the channel detection configuration, 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 1 The terminal device 101 shown, the network device may include Figure 1 Network device 102 is shown.
[0218] like Figure 3 As shown, the communication method may include the following steps:
[0219] S101: A network device sends a first configuration and at least one second configuration corresponding to the first configuration to a terminal device.
[0220] The first configuration includes a CSI configuration, and the second configuration includes an SRS configuration; or the first configuration includes an SRS configuration, and the second configuration includes a CSI configuration.
[0221] Exemplarily, the first configuration and the at least one second configuration may be carried in the same message, or the first configuration and the at least one second configuration may be carried in different messages. In addition, the network device may indicate the correspondence between the first configuration and the at least one second configuration in an explicit or implicit manner.
[0222] For example, when the correspondence between the first configuration and the second configuration is indicated in an explicit manner, the network device may send indication information (or a correspondence mapping table) to the terminal device to explicitly indicate the correspondence between the first configuration and the second configuration. For example, the indication information is used to indicate that the first configuration with an index (or number, identifier) of index 1 corresponds to the second configuration with an index of index 2; or the indication information is used to indicate that the configuration information included in the first configuration corresponds to the configuration information included in the second configuration.
[0223] When the correspondence between the first configuration and the second configuration is indicated in an implicit manner, the network device may carry the first configuration (and / or information such as the index of the first configuration) and the second configuration (and / or information such as the index of the second configuration) in the same information element (or field or message) to indicate the correspondence between the first configuration and the second configuration. Alternatively, the network device may carry the first configuration (and / or information such as the index of the first configuration) and the second configuration (and / or information such as the index of the second configuration) in adjacent information elements (or fields). For example, when the information element in which the first configuration is located is located earlier and the information element in which the second configuration is located is located later, the first configuration and the second configuration correspond to each other. In addition, the correspondence between the first configuration and the second configuration may also be indicated by carrying indication information (such as a specific field or a specific value) in the information element (or field or message) including the first configuration (and / or information such as the index of the first configuration) and carrying the same indication information in the information element (or field or message) including the second configuration (and / or information such as the index of the second configuration).
[0224] For example Figure 4 As shown, through S101, the terminal device can obtain the corresponding relationship between CSI configuration 1 and SRS configuration 1, and the corresponding relationship between CSI configuration 2, SRS configuration 2, and SRS configuration 3 based on the configuration of the network device. It can be understood that CSI configuration 1 can be used as the first configuration and SRS configuration 1 as the second configuration, or SRS configuration 1 can be used as the first configuration and CSI configuration 1 as the second configuration. In addition, if CSI configuration 2 is used as the first configuration, SRS configuration 2 and SRS configuration 3 can be used as the second configuration, or if SRS configuration 2 (or SRS) is used as the first configuration, CSI configuration 1 can be used as the second configuration.
[0225] Correspondingly, the terminal device receives the first configuration and receives at least one second configuration corresponding to the first configuration.
[0226] S102: The network device sends first information to the terminal device, where the first information is used to activate a first configuration.
[0227] The first information here can be carried in RRC signaling, MAC CE or DCI to improve configuration flexibility.
[0228] Accordingly, the terminal device receives the first information. In response to the first information, the terminal device may execute one of steps S103 or S104.
[0229] S103: The terminal device activates the first configuration and the third configuration, where the third configuration is one of the at least one second configuration.
[0230] For example Figure 4 As shown, when the first information is used to activate CSI configuration 1, the terminal device may activate CSI configuration 1, and thus may measure and / or report CSI according to CSI configuration 1, and at the same time, the terminal device activates SRS configuration 1, and thus sends SRS according to the SRS configuration 1. Alternatively, when the first information is used to activate SRS configuration 1, the terminal device may activate SRS configuration 1, and thus send SRS according to the SRS configuration 1, and at the same time, the terminal device activates CSI configuration 1, and thus may measure and / or report CSI according to CSI configuration 1.
[0231] S104: The terminal device activates the first configuration and deactivates the third configuration, where the third configuration is one of the at least one second configuration.
[0232] For example Figure 4 As shown, when the first information is used to activate CSI configuration 1, the terminal device may activate CSI configuration 1, and thus may measure and / or report CSI according to CSI configuration 1, and at the same time the terminal device deactivates SRS configuration 1, and thus no longer sends SRS according to SRS configuration 1. Alternatively, when the first information is used to activate SRS configuration 1, the terminal device may activate SRS configuration 1, and thus send SRS according to SRS configuration 1, and at the same time the terminal device deactivates CSI configuration 1, and thus no longer measures and reports CSI according to CSI configuration 1, or no longer reports CSI according to CSI configuration 1.
[0233] By adopting the above process, the terminal device can activate the first configuration after receiving the first information, and activate or deactivate the third configuration at the same time. Therefore, the activation or deactivation of the third configuration no longer depends on the message sent by the network device for activating or deactivating the third configuration, which can improve the flexibility of activation and deactivation of the channel detection configuration.
[0234] In addition, if Figure 5 As shown, another communication method provided in an embodiment of the present application may include the following steps:
[0235] S201: A network device sends a first configuration and at least one second configuration corresponding to the first configuration to a terminal device.
[0236] The first configuration includes a CSI configuration, and the second configuration includes an SRS configuration; or the first configuration includes an SRS configuration, and the second configuration includes a CSI configuration.
[0237] The sending methods of the first configuration and the second configuration mentioned above may refer to the description in S101.
[0238] Correspondingly, the terminal device receives the first configuration and at least one second configuration corresponding to the first configuration.
[0239] S202: The network device sends first information to the terminal device, where the first information is used to deactivate the first configuration.
[0240] Correspondingly, the terminal device receives the first information.
[0241] In response to the first information, the terminal device may execute one of steps S103 or S104.
[0242] S203: The terminal device deactivates the first configuration and activates a third configuration, where the third configuration is one of the at least one second configuration.
[0243] Still Figure 4 Taking the corresponding relationship shown as an example, when the first information is used to deactivate CSI configuration 1, the terminal device may deactivate CSI configuration 1, and thus no longer measure and report CSI according to CSI configuration 1, or no longer report CSI according to CSI configuration 1, and at the same time the terminal device activates SRS configuration 1, and thus sends SRS according to SRS configuration 1. Alternatively, when the first information is used to deactivate SRS configuration 1, the terminal device may deactivate SRS configuration 1, and thus no longer send SRS according to SRS configuration 1, and at the same time the terminal device may activate CSI configuration 1, and thus may measure and / or report CSI according to CSI configuration 1.
[0244] S204: The terminal device deactivates the first configuration and deactivates the third configuration, where the third configuration is one of the at least one second configuration.
[0245] For example Figure 4As shown, when the first information is used to deactivate CSI configuration 1, the terminal device may deactivate CSI configuration 1, and thus no longer measure and report CSI according to CSI configuration 1, or no longer report CSI according to CSI configuration 1, and at the same time, the terminal device deactivates SRS configuration 1, and thus no longer sends SRS according to the SRS configuration 1. Alternatively, when the first information is used to deactivate SRS configuration 1, the terminal device may deactivate SRS configuration 1, and thus no longer send SRS according to the SRS configuration 1, and at the same time, the terminal device deactivates CSI configuration 1, and thus no longer measure and report CSI according to CSI configuration 1, or no longer reports CSI according to CSI configuration 1.
[0246] By adopting the above process, the terminal device can deactivate the first configuration after receiving the first information, and activate or deactivate the third configuration at the same time. Therefore, the activation or deactivation of the third configuration no longer depends on the RRC message sent by the network device for the third configuration, which can improve the flexibility of activation and deactivation of the channel detection configuration.
[0247] In the above Figure 3 and / or Figure 5 In the process shown, if the first configuration corresponds to multiple second configurations, the first information may also include information of the third configuration, so the terminal device can activate or deactivate the third configuration according to the information of the third configuration.
[0248] For example, the information of the third configuration may include the index of the third configuration. For example, the first configuration corresponds to N second configurations, N is a positive integer and N is greater than 1, and according to the order of configuring the second configurations, the index of each second configuration is #0, #1...#N-1. When the first information includes the index #0, the terminal device 101 can determine that the third configuration is the first second configuration configured by the network device. The configuration order, for example, when multiple second configurations are indicated in the same message, the order in which the information elements of the second configurations are arranged, or when multiple second configurations are indicated through different messages, the order in which the messages containing the second configurations are sent.
[0249] For another example, the information of the third configuration may further include an identifier of the third configuration. For example, when the network device indicates at least one second configuration corresponding to the first configuration to the terminal device, it carries an identifier for each second configuration, and subsequently carries the identifier of the third configuration in the first information.
[0250] Optionally, when the third configuration includes a specific CSI configuration, the terminal device no longer performs CSI measurement and / or reporting after activating the third configuration.
[0251] Accordingly, when the third configuration includes a specific CSI configuration and the terminal device activates the third configuration, the network device may not receive CSI reports from the terminal device. For example, the network device assumes that the terminal device will activate the third configuration after receiving the first information, or in other words, the first information is also used to activate the third configuration corresponding to the first configuration. If the first information includes instruction information for instructing the terminal device to activate the third configuration, the network device will not receive CSI reports from the terminal device.
[0252] If multiple terminal devices served by the network device are in a state of not performing CSI measurement and reporting CSI, for example, the third configuration activated by multiple terminal devices served by the network device are all the specific CSI configuration, then the network device may not send CSI resources, or in other words, the network device may not send CSI-RS, and the CSI resources are used for the terminal devices served by the network device to determine the CSI.
[0253] Among them, the specific CSI configuration is, for example, an empty CSI configuration, or a CSI configuration with parameters set to specific values, or a CSI configuration carrying a specific field. For example, there is a field in the CSI configuration indicating whether the configuration is a specific CSI configuration or not. If a field indicating "is a specific CSI configuration" appears in the CSI configuration, it indicates that the CSI configuration is a specific CSI configuration.
[0254] The specific CSI configuration may be configured by the terminal device through pre-configuration, or may be configured by the network device through high-layer signaling, etc.
[0255] For another example, when the uplink and downlink channels are reciprocal, the network device can allow the terminal device to activate an SRS configuration with a smaller SRS period. At the same time, this SRS configuration corresponds to an empty CSI configuration (i.e., a specific CSI configuration). Therefore, the terminal device can activate this empty CSI configuration and no longer perform CSI measurements and / or reports. In this way, the terminal device mainly relies on sending SRS to allow the network device to monitor channel quality, and the terminal device no longer needs to perform CSI measurements and reports, thereby reducing power consumption.
[0256] Similarly, when the first configuration includes a specific CSI configuration, the terminal device no longer performs CSI measurement and / or reporting after activating the first configuration.
[0257] The embodiment of the present application provides another communication method, in which a terminal device can report a channel detection configuration preference to a network device to assist the network device in configuring the channel detection configuration. Figure 6 As shown, the method may include the following steps:
[0258] S301: The terminal device sends second information to the network device.
[0259] The second information is used to indicate the channel detection configuration preference of the terminal device.
[0260] Before sending the second information, the terminal device may determine the second information.
[0261] It should be understood that the above channel sounding configuration includes CSI configuration and / or SRS configuration.
[0262] S302: The network device receives the second information.
[0263] By adopting the above method, the terminal device can report its own preference for channel detection configuration to the network device as auxiliary information to help the network device configure the channel detection configuration of the terminal device, thereby improving the configuration efficiency of the channel detection configuration.
[0264] Optionally, the network device determines the channel detection configuration of the terminal device based on the second information.
[0265] If the network device determines the channel sounding configuration of the terminal device according to the second information, the network device may send the channel sounding configuration to the terminal device, where the channel sounding configuration is determined according to the second information.
[0266] Several possible implementations of the second information are described below by way of examples.
[0267] In one possible implementation, the second information may indicate a channel sounding type preferred by the terminal device. The channel sounding type preferred by the terminal device may include: sending only SRS (or, not performing CSI measurement and reporting, or downlink channel sounding), performing only CSI measurement and reporting (or, not performing SRS measurement, or uplink channel sounding), and sending SRS and performing CSI measurement and reporting (or, uplink channel sounding and downlink channel sounding).
[0268] Among them, "only sending SRS" means that the terminal device sends SRS without measuring and reporting CSI, and there is no specific limitation on whether the terminal device performs operations other than sending SRS. "Only performing CSI measurement and reporting" means that the terminal device measures and reports CSI without sending SRS, and there is no specific limitation on whether the terminal device performs operations other than CSI measurement and reporting. "Sending SRS and performing CSI measurement and reporting" means that the terminal device performs CSI measurement and reporting and sends SRS.
[0269] Optionally, the channel detection type preferred by the terminal device can be determined by the terminal device based on its own historical configuration, its own power saving requirements, and service quality requirements. When determined based on its own historical configuration, for example, the channel detection configuration most recently configured by the network device to the terminal device is to only perform CSI measurement and reporting without sending SRS, then the terminal device can determine the preferred channel detection type to be only CSI measurement and reporting. When determined based on its own power saving requirements, for example, the power consumption required for the terminal device to send SRS is lower than the power consumption required for CSI measurement and reporting, if the terminal device wants to save power, it can report the second information indicating that the terminal device prefers to "only send SRS". When determined based on its own power saving requirements, if the quality of service (QoS) requirements of the terminal device's current service are high, and the terminal device hopes to have more timely monitoring of the channel quality, the terminal device can report the second information indicating that the terminal device prefers to "send SRS and perform CSI measurement and reporting".
[0270] Optionally, the terminal device may determine a preferred channel detection type based on its own capabilities, mobility, moving speed, or channel quality information.
[0271] For example, when the terminal device has high mobility or a high speed, the frequency and degree of channel state changes may be relatively large. The terminal device can report second information indicating that the terminal device prefers to "send SRS and perform CSI measurement and reporting" or to "only perform CSI measurement and reporting." This allows the terminal device to monitor the downlink channel quality itself, so that the terminal device and network equipment can obtain more real-time channel state information and perceive the communication quality in a timely manner. Conversely, when the terminal device has low mobility or a low speed, the frequency and degree of channel state changes may be relatively small. The terminal device can report second information indicating that the terminal device prefers to "only send SRS." Therefore, the terminal device can only send SRS and save power.
[0272] For another example, when the current channel quality is determined to be poor based on parameters such as reference signal received power (RSRP), reference signal received quality (RSRQ) and / or signal to interference plus noise ratio (SINR), the terminal device can report a second information indicating that the terminal device prefers to "send SRS and perform CSI measurement and reporting" or "only perform CSI measurement and reporting", so that the terminal device monitors the downlink channel quality by itself, so that the terminal device and the network can obtain more real-time channel status information and perceive the communication quality in a timely manner. Conversely, if the channel quality is good, the terminal device can report a second information indicating that the terminal device prefers to "only send SRS", so that the terminal device can only send SRS and save power.
[0273] For another example, the terminal device determines whether it is currently capable of performing CSI measurement reporting and / or sending SRS based on its real-time terminal device capabilities.
[0274] It should be understood that the terminal device can comprehensively consider information such as its own capabilities, mobility, moving speed and channel quality to comprehensively determine its preferred channel detection type. The specific method can refer to the above example.
[0275] Optionally, the terminal device may learn a preferred channel detection type through artificial intelligence (AI) based on historical channel detection configurations, its own capabilities, mobility, moving speed, or current channel quality.
[0276] In another possible example, the second information may indicate at least one of the CSI configuration preferred by the terminal device (including the preferred CSI resource configuration and / or the preferred CSI reporting configuration) or the preferred SRS configuration.
[0277] Optionally, the preferred CSI configuration or preferred SRS configuration may be determined by the terminal device based on its historical configuration. For example, the terminal device's preferred CSI configuration may be determined based on the terminal device's historical CSI configuration, such as using the terminal device's most recently used CSI resource configuration as the preferred CSI resource configuration. For another example, the terminal device's preferred SRS configuration may be determined based on the terminal device's historical SRS configuration.
[0278] Optionally, the terminal device can evaluate its power consumption under different CSI and / or SRS configurations, i.e., it can determine which configurations have higher power consumption and which configurations have lower power consumption. If the terminal device needs to save power, it can select the configuration that it has historically used to reduce power consumption as its preferred configuration and report this via the second information.
[0279] Optionally, the terminal device may determine at least one of a preferred CSI resource configuration, a preferred CSI reporting configuration, or a preferred SRS configuration based on its own capabilities, mobility, mobile speed, or current channel quality information.
[0280] For example, when the terminal device has high mobility or a high mobile speed, the frequency and degree of channel state changes may be relatively large. The terminal device can report a CSI resource configuration with a smaller resource period or reporting period as the preferred CSI configuration, or an SRS configuration with a smaller reporting period as the preferred SRS configuration, so that the terminal device and the network can obtain more real-time channel state information and perceive communication quality in a timely manner. Conversely, when the terminal device has low mobility or a low mobile speed, the terminal device can report a CSI configuration with a larger resource period or reporting period as the preferred CSI configuration, or an SRS configuration with a larger reporting period as the preferred SRS configuration, so that the terminal device can save power.
[0281] For example, when a terminal device determines that the channel quality is poor, the terminal device may report a CSI configuration with a shorter resource period or reporting period as the preferred CSI configuration, or an SRS configuration with a shorter reporting period as the preferred SRS configuration, so that the terminal device and the network can obtain more real-time channel state information and perceive the communication quality in a timely manner. Conversely, if the channel quality is good, the terminal device may report a CSI configuration with a longer resource period or reporting period as the preferred CSI configuration, or an SRS configuration with a longer reporting period as the preferred SRS configuration, so that the terminal device can save power.
[0282] For another example, the terminal device may determine, based on its real-time terminal device capabilities, the CSI configuration it can currently accept and report as the preferred CSI configuration, and / or determine the SRS configuration it can currently accept and report as the preferred SRS configuration.
[0283] It should be understood that the terminal device can comprehensively consider its own capabilities, mobility, mobile speed, channel quality and other information to comprehensively determine its own preferred CSI configuration and / or SRS configuration. The specific method can refer to the above examples.
[0284] Optionally, the terminal device may learn at least one of the preferred CSI resource configuration, preferred CSI reporting configuration or preferred SRS configuration through artificial intelligence based on historical channel detection configuration, its own capabilities, mobility, mobile speed or current channel quality information.
[0285] It should be understood that the implementation of the second information is not limited to the above examples, and may also be implemented by combining or simply modifying the above examples. For example, the second information includes information indicating the channel sounding type preferred by the terminal device, and also includes at least one of the preferred CSI resource configuration, the preferred CSI reporting configuration, or the preferred SRS configuration.
[0286] like Figure 7 As shown, in another communication method provided by an embodiment of the present application, the network device can control the terminal device to activate (or enable) or deactivate (or disable) periodic CSI measurement and / or reporting through third information. The method may include the following steps:
[0287] S401: The network device sends third information to the terminal device, where the third information is used to activate or deactivate periodic CSI measurement and / or reporting of the terminal device.
[0288] Optionally, the third information may be used to activate or deactivate periodic CSI resource configuration and / or periodic CSI reporting configuration.
[0289] Optionally, the third information may be carried in RRC signaling, MAC CE signaling or DCI.
[0290] S402: The terminal device receives the third information.
[0291] If the third information is used to activate periodic CSI measurement and / or reporting of the terminal device, the terminal device may perform CSI measurement and reporting in response to the third information. The CSI configuration based on which the CSI measurement and reporting are performed may be configured independently by the network device, or may adopt a previous CSI measurement and reporting configuration.
[0292] If the third information is used to deactivate periodic CSI measurement and / or reporting of the terminal device, the terminal device may no longer measure and report CSI, or no longer report CSI, in response to the third information.
[0293] This method can flexibly implement periodic CSI activation, reducing the signaling overhead and latency when activating the periodic CSI of a terminal device. It can also implement a flexible periodic CSI deactivation solution, reducing the signaling overhead and latency when deactivating the periodic CSI of a terminal device.
[0294] Exemplarily, if the third information is used to activate the CSI resource configuration and / or reporting configuration of the terminal device, the third information is used to activate periodic CSI measurement and / or reporting of the terminal device. For example, if the third information is used to activate the CSI resource configuration of the terminal device, the third information can be used to activate CSI measurement.
[0295] If the third information is used to deactivate the CSI resource configuration and / or reporting configuration of the terminal device, the third information is used to deactivate the periodic CSI measurement and / or reporting of the terminal device. For example, if the third information is used to deactivate the CSI resource configuration of the terminal device, the third information can be used to deactivate CSI measurement.
[0296] Optionally, when the third information is used to activate periodic CSI measurement and / or reporting of the terminal device, the terminal device may send a channel state information report to the network device according to the CSI resource configuration and / or reporting configuration.
[0297] Optionally, when the third information is used to deactivate the CSI measurement of the terminal device, the terminal device does not determine the channel state information based on the CSI resource configuration.
[0298] When the third information is used to deactivate the CSI reporting of the terminal device, the terminal device does not send a channel state information report to the network device according to the CSI reporting configuration.
[0299] When the third information is used to deactivate the CSI measurement and reporting of the terminal device, the terminal device does not determine the channel state information according to the CSI resource configuration, and does not send a channel state information report to the network device according to the CSI reporting configuration.
[0300] Optionally, if the third information is carried by MAC CE, the third information may be carried in a specific MAC CE, and the specific MAC CE may be used to activate (or deactivate) the CSI resources of the SP, and / or to activate (or deactivate) the CSI reporting of the SP.
[0301] Furthermore, specific information may be carried in the specific MAC CE to indicate that the third information carried in the specific MAC CE is used to enable or disable periodic CSI rather than SP CSI. For example, the specific information may occupy reserved bits in the specific MAC CE or reuse other existing (or defined) bits. In addition, the specific information may also occupy newly added bits (or newly added information elements) in the specific MAC CE, where the newly added bits are added to carry the specific information.
[0302] Optionally, the third information may be carried by a newly defined RRC message, MAC CE signaling or DCI.
[0303] 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.
[0304] Figure 8 Schematic block diagram of a communication device provided in an embodiment of the present application. For example, the communication device is Figure 8 The terminal device 800 is shown.
[0305] The terminal device 800 includes a processing module 810 and a transceiver module 820. Exemplarily, the terminal device 800 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 800 is a terminal device, the transceiver module 820 may be a transceiver, which may include an antenna and a radio frequency circuit, etc., and the processing module 810 may be a processor, such as a baseband processor, which may include one or more central processing units (CPUs). When the terminal device 800 is a component having the above-mentioned terminal device functions, the transceiver module 820 may be a radio frequency unit, and the processing module 810 may be a processor, such as a baseband processor. When the terminal device 800 is a chip system, the transceiver module 820 may be the input and output interface of the chip (such as a baseband chip), and the processing module 810 may be the processor of the chip system, which may include one or more central processing units. It should be understood that the processing module 810 in the embodiments of the present application may be implemented by a processor or processor-related circuit components, and the transceiver module 820 may be implemented by a transceiver or transceiver-related circuit components.
[0306] For example, the processing module 810 can be used to perform Figure 3 or Figures 5 to 7 All operations except the transceiver operations performed by the terminal device in any of the illustrated embodiments, such as S103, S104, S203 and S204, and / or other processes for supporting the technology described herein, such as generating messages, information and / or signaling sent by the transceiver module 820, and processing messages, information and / or signaling received by the transceiver module 820, such as activating and deactivating CSI measurement and / or CS reporting configuration, and performing CSI measurement according to the CSI configuration.
