Communication method and device

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a communication method and apparatus.

Background

In wireless communication technology, a transmitting end can utilize detected wireless channel information to assist transmission. The wireless channel information may be acquired in various manners, but no matter what manner is used to acquire the channel information, a transmitting end or a receiving end is required to measure a specific reference signal to estimate the characteristics of the wireless channel. This process of estimating the characteristics of the radio channel is called channel sounding (channel sounding). Aiming at a downlink channel and an uplink channel, the channel detection types respectively comprise downlink channel detection and uplink channel detection.

The existing de-enabling mode of downlink channel detection is not flexible enough, and cannot meet the requirement that terminal equipment flexibly adjusts the channel detection mode.

Illustratively, the first communication device is a terminal device, or a chip provided in the terminal device for implementing a function of the terminal device, or another component for implementing a function of the terminal device. In the following description, the first communication apparatus is exemplified as a terminal device.

The method comprises the following steps: the terminal device may receive first information for enabling measurement of channel state information; and/or the first information is used for enabling the reporting of the channel state information. The terminal device does not report channel state information to the network device.

By adopting the mode, the network equipment can indicate the terminal equipment to enable the reporting of the channel state information through the first information, so that the flexibility of enabling the reporting of the CSI is improved.

In one possible design, the terminal device may not perform the measurement of the channel state information when the first information is used to disable the measurement of the channel state information. The design can flexibly control the terminal equipment to enable the measurement of the channel state information so as to flexibly adjust the power consumption of the terminal equipment.

After a first time length after 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. Therefore, the terminal equipment can measure and report the channel state information according to the first time length recovery, and does not need to configure new channel state information resource configuration and channel state information reporting configuration by the network equipment before the measurement and the reporting are recovered, and the corresponding configuration before the measurement and the reporting is suspended, so that the signaling overhead is saved.

In one possible design, the terminal device may stop reporting the channel state information according to the first channel state information reporting configuration. And after a first time length after the first information is received, the terminal equipment reports the channel state information to the network equipment according to the first channel state information reporting configuration. Therefore, the terminal equipment can recover the reporting of the channel state information according to the first time length, does not need to configure new channel state information reporting configuration by the network equipment before the reporting is recovered, continues to use the corresponding configuration before the reporting is suspended, and saves signaling overhead.

In one possible design, the terminal device receives second information, where the second information is used to indicate a plurality of durations, and the first information is further used to indicate the first duration from the plurality of durations.

In a 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. In addition, the terminal device may delete the first channel state information resource configuration and/or the first channel state information reporting configuration. Therefore, the terminal equipment can stop the measurement and report of the channel state information according to the first information and delete the corresponding measurement configuration and report configuration, thereby stopping executing the downlink channel detection and saving the power consumption.

The terminal device 101 may be a communication chip having a communication module, a vehicle having a communication function, an in-vehicle device (e.g., an in-vehicle communication apparatus, an in-vehicle communication chip), or the like.

Network device 102 may be an access network device (or access network site). The access network device refers to a device providing a network access function, such as a Radio Access Network (RAN) base station, and the like. The network device 102 may specifically include a Base Station (BS), or include a base station and a radio resource management device for controlling the base station, and the like. The network device 102 may also include relay stations (relay devices), access points, and base stations in future 5G networks, base stations or NR base stations in future evolved PLMN networks, and so on. The network device 102 may be a wearable device or a vehicle-mounted device. The network device 102 may also be a communication chip having a communication module.

For example, network devices 102 include, but are not limited to: next generation base stations (gnbs ) in 5G, evolved node bs (enbs) in LTE systems, radio Network Controllers (RNCs), radio controllers under CRAN systems, base Station Controllers (BSCs), home base stations (e.g., home evolved node bs or home node bs, HNBs), base Band Units (BBUs), transmission points (TRPs), transmission Points (TPs), or mobile switching centers (msc). The network device 102 may also include a base station in a future 6G or newer mobile communication system.

In addition, as shown in fig. 2a, in the embodiment of the present application, data or control signaling may also be transmitted to a single or multiple terminal devices by a network device, or as shown in fig. 2b, data or control signaling may be transmitted to a single terminal device by multiple network devices. For the description of the terminal device and the network device shown in fig. 2a or fig. 2b, reference may be made to the description of the terminal device 101 and the network device 102.

The following describes a channel sounding method in the prior art by taking the system shown in fig. 1 as an example.

A typical downlink channel sounding is performed based on a downlink channel state information reference signal (CSI-RS), that is, the terminal device 101 measures a CSI-RS signal sent by the network device 102 according to CSI resource configuration sent by the network device 102 to obtain downlink channel characteristics, and the terminal device 101 reports the downlink channel characteristics to the network device 102 according to CSI reporting configuration (report configuration) sent by the network device 102.

The CSI-RS resources may be classified into three types, i.e., periodic (periodic), semi-persistent (SP), and aperiodic (aperiodic), according to time domain characteristics.

For periodic CSI-RS resources, terminal device 101 considers that the transmission of CSI-RS is repeated every N time units (time units). The following description will be given with a time unit as a slot (slot). The minimum value of N may be 4, that is, the network device 102 transmits the CSI-RS once every 4 slots. The maximum value of N may be 640, i.e., the network device 102 transmits the CSI-RS once every 640 slots. In addition to the period, the terminal device 101 needs to know a specific offset (offset) to find the time domain position of the CSI-RS. Taking the offset as a slot offset (slot offset) as an example, terminal device 101 needs to know how many slots CSI-RS is shifted by the transmission time in one period in order to determine the time domain position of the CSI-RS.

For the CSI-RS resources of the SP, the network device 102 may configure the transmission periodicity and offset of the CSI-RS of the SP. In addition, the semi-persistently transmitted CSI-RS is controlled by an SP CSI resource set activation/deactivation related Media Access Control (MAC) control element (MAC CE), i.e., the MAC CE can activate/deactivate transmission of the CSI-RS resources of the SP. After network device 102 activates the CSI-RS resource of the SP through the MAC CE, terminal device 101 may consider that the CSI-RS resource of the SP is periodically transmitted according to the configured parameters until it is deactivated by the MAC CE. When the network device 102 deactivates the CSI-RS resource of the SP through the MAC CE, the terminal device 101 may consider that the network device 102 no longer transmits the CSI-RS resource of the SP.

For aperiodic CSI-RS, the network device 102 does not configure the transmission periodicity or offset of the CSI-RS. The network device 102 triggers sending of the CSI-RS resource through Downlink Control Information (DCI), that is, the network device 102 notifies the UE through DCI before sending the CSI-RS resource each time.

Based on the configuration of network device 102, terminal device 101 may perform different CSI measurements. For most measurements, the terminal device 101 needs to report the measurement result to the network device 102. In this case, the network device 102 may set how the UE sends the CSI report (CSI report) through the CSI report configuration.

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

For periodic CSI reporting, the network device 102 needs to configure a certain reporting period for the terminal device 101, where the periodic reporting is carried by a Physical Uplink Control Channel (PUCCH), that is, the periodic CSI report is sent on the PUCCH.

For the CSI reporting of the SP, the network device 102 configures a certain reporting period. In addition, the CSI reporting of the SP is controlled by activating/deactivating the relevant MAC CE or DCI in the SP CSI reporting. When the network device 102 activates the CSI reporting of the SP through the MAC CE, the terminal device 101 transmits a CSI report on the PUCCH; when the network device 102 triggers CSI reporting of the SP through the DCI, the terminal device 101 sends the CSI report on a Physical Uplink Shared Channel (PUSCH).

For aperiodic CSI reporting, the network device 102 triggers aperiodic CSI reporting through DCI, and more specifically, through a CSI request (CSI-request) field in the DCI. The aperiodic report is carried by a Physical Uplink Shared Channel (PUSCH), that is, the aperiodic CSI report is sent on the PUSCH.

The reporting amount (report quality) in the CSI report includes, but is not limited to, the following: a Channel Quality Indicator (CQI) is used to indicate a coding and modulation scheme proposed by the terminal apparatus 101. A Precoding Matrix Indicator (PMI) for indicating an optimal precoding matrix suggested by the terminal apparatus 101. A CSI-RS resource indicator (CRI). An SSB resource indicator (SS/PBCH block resource indicator, SSBRI). A Layer Indicator (LI) for indicating the strongest layer. A Rank Indicator (RI) for indicating the optimal number of layers for downlink transmission suggested by the terminal apparatus 101. Layer 1reference signal received power (L1-RSRP). And the reporting quantity carried in the CSI report is determined according to the CSI reporting configuration.

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

In the prior art, the network device 102 needs to provide a downlink channel sounding configuration to the terminal device 101 through an RRC reconfiguration message, so as to activate downlink channel sounding; or, in addition to providing a set of downlink channel sounding configuration through the RRC reconfiguration message, the network device needs to indicate activation of the channel sounding configuration through a 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, it is also necessary for the network device 102 to instruct the terminal device 101 to delete the downlink channel sounding configuration through an RRC reconfiguration message, or for the network device to instruct the downlink channel sounding configuration to be deactivated through a separate signaling.

Therefore, at present, the start (or referred to as enable) or stop (or referred to as disable) of downlink channel sounding of the terminal device depends on the activation and deactivation of the network device for the downlink channel sounding configuration, and therefore, the enabling and disabling modes of the downlink channel sounding are not flexible enough, and the requirement of flexibly controlling whether the terminal device executes the downlink channel sounding cannot be met.

In order to optimize an enabling and disabling scheme of downlink channel sounding, embodiments of the present application provide a communication method. The communication method may be performed by a terminal device and a network device. The terminal device comprises terminal device 101 shown in fig. 1, and the network device may comprise network device 102 shown in fig. 1.

As shown in fig. 3, the communication method may include the steps of:

s101: the network device sends the first information to the terminal device. The first information is used to disable measurement of the CSI; and/or the first information is used for enabling the reporting of the CSI.

Accordingly, the terminal device receives the first information.

S102: the terminal device does not send a CSI report to the network device.

It should be understood that reporting CSI (or reporting of CSI) in the present network application includes the terminal device sending a CSI report to the network device, and then reporting CSI or reporting of CSI may be used to indicate that the terminal device sends a CSI report to the network device.

Accordingly, the network device does not receive a CSI report from the terminal device.

Optionally, if the first information indicates that the terminal device disables measurement of the CSI or indicates that the terminal device disables measurement of the CSI and reports the CSI, the terminal device does not perform measurement of the CSI after receiving the first information and does not send the CSI to the network device. If the first information indicates that the terminal equipment can report the CSI, the terminal equipment does not send the CSI to the network equipment, but the terminal equipment can measure the CSI or does not measure the CSI.

By adopting the above mode, the network device can enable the terminal device to report the CSI through the first information, so that the flexibility when the CSI is enabled to be reported is improved.

Similarly, in the above process, the first information may also be replaced by information for indicating measurement of the enabled CSI and/or reporting of the enabled CSI, and the terminal device performs reporting of the CSI after receiving the first information, so as to improve flexibility when reporting the enabled CSI.

Optionally, the CSI includes at least one of periodic channel state information, semi-persistent channel state information, or aperiodic channel state information. That is, the above scheme may be applied in the configuration process of periodic channel state information, semi-persistent channel state information, or aperiodic channel state information.

For example, the above first information may be carried in an RRC message, a MAC CE, or a DCI.

Optionally, after S102, the terminal device may resume performing CSI measurement and reporting according to the first time duration or according to an indication of the network device, so as to more flexibly implement enabling of CSI measurement and/or reporting.

In S102, when the terminal device stops measuring the CSI according to the first CSI resource configuration and stops reporting the CSI according to the first CSI reporting configuration, the terminal device may measure the CSI according to the first CSI resource configuration after a first duration elapses after receiving the first information, and report the CSI to the network device according to the first CSI reporting configuration, so as to resume measurement and reporting of the CSI.

In this example, suspension of CSI measurement and reporting (or temporary de-enabling of CSI measurement and reporting) of the terminal device may be implemented to control the terminal device to implement enabling and de-enabling more flexibly. And the CSI measurement configuration and the CSI reporting configuration do not need to be deleted when the CSI measurement and the reporting are suspended, the CSI measurement configuration and the CSI reporting configuration do not need to be reconfigured before the CSI reporting is resumed, and the CSI measurement and the reporting are still performed according to the CSI configuration before the suspension after the CSI measurement and the reporting are resumed, so that the expenditure is saved.

Optionally, the first time duration is preconfigured, and meanwhile, the network device is provided with the same first time duration, and is configured to resume receiving CSI from the terminal device after the terminal device receives the first information (or after the network device sends the first information) for the first time duration. For example, the first time period is preset to a set value.

Alternatively, the first duration may be indicated by the network device. For example, the first information may include the first time duration or indication information of the first time duration. For example, the network device may further send second information to the terminal device, where the second information may be used to indicate the plurality of durations, and in addition, the network device sends first information to the terminal device, where the first information includes indication information of the first duration, and is used to indicate the first duration from the plurality of durations.

The second information may be carried in a different Information Element (IE) in the same message as the first information, or the first information may be carried in a different signaling than the second information.

Optionally, the first time period may also be determined according to the moving speed and/or the moving state of the terminal device.

One possible implementation manner is that the network device may send third information to the terminal device, where the third information may be used to indicate a plurality of time durations, and thereafter, the terminal device may determine the first time duration from the plurality of time durations according to its own moving speed and/or mobility state.

The mobile speed and/or the mobility state of the terminal device correspond to the plurality of durations one to one, the terminal device may determine a first duration corresponding to the mobile speed and/or the mobility state of the terminal device according to a first corresponding relationship, where the first corresponding relationship is a corresponding relationship between the plurality of durations and the plurality of mobile speeds and/or the mobility states, the plurality of durations included in the first corresponding relationship may include the plurality of durations indicated by the third information, and the plurality of durations indicated by the third information include the first duration. Wherein the first correspondence is pre-configured.

Alternatively, the first correspondence may be sent by the network device to the terminal device, for example, the third information is used to indicate the first correspondence, that is, to indicate the correspondence between the plurality of time lengths and the plurality of moving speeds and/or moving states. The first correspondence relationship may be indicated by a mapping table, etc., and the present application is not particularly limited.

Examples of the above first correspondence relationship are shown in table 1.

Moving speed (meter/minute (m/min))	Mobility state	Duration (second (s))
≤20	-	20
20＜X≤200	-	10
X＞200	-	5
-	High mobility	15
-	Low mobility	25

TABLE 1

The above table 1 is only exemplary, and in actual use, the correspondence between a plurality of moving speeds and a plurality of time lengths may be used as a mapping table, and/or the correspondence between a plurality of moving states and a plurality of time lengths may be used as a mapping table, which is not limited in this application. In addition, the settings of the moving speed, the mobility state, and the duration in table 1 are only exemplary examples, and should not be construed as being limited thereto.

Similarly, in S102, when the terminal device stops reporting the CSI according to the first CSI reporting configuration, the terminal device may resume reporting the CSI to the network device according to the first CSI reporting configuration after a first duration elapses after receiving the first information. At this time, the terminal device may continue to perform CSI measurement, but need not perform CSI reporting.

Therefore, the suspension of the CSI reporting (or called temporary disabling of the CSI reporting) of the terminal equipment can be realized, so that the terminal equipment is controlled to more flexibly realize the enabling and disabling of the CSI reporting. And the CSI reporting configuration does not need to be deleted when the CSI reporting is suspended, the CSI reporting configuration does not need to be reconfigured before the CSI reporting is resumed, and the CSI is measured and reported according to the CSI configuration before the suspension after the CSI reporting is resumed, so that the cost is saved.

The first duration may be determined by referring to the above description, and will not be described again.

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, the first information is used to enable CSI measurement, the fourth information is used to enable CSI measurement, the first information is used to enable CSI measurement and CSI reporting, and the fourth information is used to enable CSI measurement and reporting.

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

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

In this example, suspension of CSI measurement and reporting (or temporary de-enabling of CSI measurement and reporting) of the terminal device may be implemented to control the terminal device to implement enabling and de-enabling more flexibly. And the CSI measurement configuration and the CSI reporting configuration do not need to be deleted when the CSI measurement and the reporting are suspended, the CSI measurement configuration and the CSI reporting configuration do not need to be reconfigured before the CSI reporting is resumed, and the CSI measurement and the reporting are still performed according to the CSI configuration before the suspension after the CSI measurement and the reporting are resumed, so that the cost is saved.

Similarly, in S102, when the terminal device stops reporting the CSI according to the first CSI reporting configuration, the terminal device may continue to perform CSI measurement, but does not perform CSI reporting any more, and after receiving the fifth information, the terminal device may resume reporting the CSI to the network device according to the first CSI reporting configuration, and does not need to reconfigure the CSI measurement configuration and the CSI reporting configuration before resuming CSI reporting. Or, when the terminal device stops reporting the CSI according to the first CSI reporting configuration, the terminal device may stop performing the CSI measurement according to the first CSI resource configuration, and after receiving the fifth information, the terminal device may resume performing the CSI measurement according to the first CSI resource configuration and resume reporting the CSI according to the first CSI reporting configuration, without reconfiguring the CSI measurement configuration and the CSI reporting configuration before resuming the CSI reporting.

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

Optionally, after S102 stops reporting the CSI, the terminal device may delete the CSI resource configuration and/or the CSI reporting configuration, or delete the CSI resource configuration and/or the CSI reporting configuration only when the first information is further used to delete the CSI resource configuration and/or the CSI reporting configuration, or only when the first information does not indicate that the CSI configuration is to be reserved.

The CSI measurement configuration and/or CSI reporting configuration deleted by the terminal device include, but are not limited to, a CSI resource configuration adopted before receiving the first information and/or a CSI reporting configuration adopted 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.

For example, when the terminal device stops measuring the CSI according to the first CSI resource configuration and stops reporting the CSI according to the first CSI reporting configuration, the terminal device may further delete the first CSI resource configuration and delete the first CSI reporting configuration, where the first CSI resource configuration is the CSI resource configuration adopted before receiving the first information, and the first CSI reporting configuration is the CSI reporting configuration adopted before receiving the first information. And if the terminal equipment is required to recover CSI measurement and report subsequently, the network equipment is required to resend CSI resource configuration and CSI report configuration.

Similarly, when the terminal device stops reporting the CSI according to the first CSI reporting configuration, the terminal device may further delete the first CSI reporting configuration.

In the above example, the first information may indicate the first CSI resource configuration from a plurality of CSI resource configurations of the terminal device, for example, the first information includes an identification of the first CSI resource configuration to indicate the first CSI resource configuration. Alternatively, the first information may be used to indicate to enable measurement of CSI according to the first CSI resource configuration. The first information may also indicate the first CSI reporting configuration from a plurality of 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 that reporting of the CSI according to the first CSI is disabled.

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. There may be a plurality of CSI resource configurations currently being used by the terminal device, and the first CSI resource configuration may be some or all of the plurality of resource configurations. In addition, there may be a plurality of CSI reporting configurations currently being used by the terminal device, and the first CSI resource configuration may be part or all of the plurality of reporting configurations.

As shown in fig. 4, an embodiment of the present application provides another communication method for flexibly configuring a CSI period of periodic CSI. It should be understood that the CSI period herein includes a CSI resource period and/or a CSI reporting period. The method may comprise the steps of:

s201: and the network equipment sends the sixth information to the terminal equipment. The sixth information may indicate at least one period.

Accordingly, the terminal device receives the sixth information.

S202: and the network equipment sends the seventh information to the terminal equipment. The seventh information is used to indicate that the first cycle in the at least one cycle is a CSI resource cycle and/or a CSI reporting cycle. Or, the seventh information is used to indicate a 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.

The seventh information may be carried in an RRC message, a MAC CE, or a DCI.

Accordingly, the terminal device receives the seventh information.

By adopting the method, the network equipment can indicate a plurality of periods to the terminal equipment and can dynamically indicate the CSI resource period and/or the CSI reporting period adopted by the CSI measurement report through the seventh information, so that the CSI period can be flexibly adjusted according to the channel condition and the self state of the terminal equipment, and the power consumption is saved.

Alternatively, the above sixth information may indicate a plurality of periods, and the seventh information is used to indicate the first period from the plurality of periods. For example, the seventh information may include an identification (or index, number) of the first period.

For example, the seventh information may include an identification of the first cycle in a plurality of cycles. 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, the seventh information carries identifier 1, which indicates that the first period is 5s.

Optionally, the seventh information may be used by the terminal device to determine the first period from multiple periods indicated by the sixth information according to the second period, where the second period is a CSI resource period and/or a CSI reporting period that are used before the terminal device receives the sixth information.

For example, the terminal device receives the seventh information, and when the seventh information is used to instruct the terminal device to increase the CSI resource period (and/or the 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 the CSI reporting period) adopted before the terminal device receives the seventh information is 12s, the terminal device may adjust the CSI resource period (and/or the CSI reporting period) to 15s (or 20 s) after receiving the seventh information. Or, when the terminal device is configured to instruct the terminal device to decrease the CSI resource period (and/or the 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 the CSI reporting period) adopted before the terminal device receives the seventh information is 12s, the terminal device may adjust the CSI resource period (and/or the CSI reporting period) to 10s (or 5 s) after receiving the seventh information.

The seventh period may carry an indication for instructing the terminal device to increase or decrease the CSI period, for example, carry a bit, and when the bit is 0, the seventh information is used to instruct the terminal device to increase the CSI period, that is, to select a first period larger than the second period from the plurality of periods (for example, the first period is a smallest period of at least one period larger than the second period in the plurality of periods); when the bit position is 1, the seventh information is used to instruct the terminal device to decrease the CSI period, that is, to select a first period smaller than the second period from the plurality of periods (for example, the first period is a largest period of at least one period smaller than the second period from the plurality of periods). Similarly, the seventh information may also instruct the terminal device to increase the CSI period when the ratio is set to 1, or may instruct the terminal device to increase the CSI period when the ratio is set to 0.

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 default to the first period, the periodic CSI measurement and/or CSI reporting is 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.

Accordingly, when the first period is a specific period, the network device does not receive the CSI report from the terminal device. If a plurality of terminal devices served by the network device are all in a state of not sending CSI, for example, the CSI measurement period and/or the CSI reporting period configured by the network device for the plurality of terminal devices associated therewith are both the specific period, the network device may not send a CSI resource, or alternatively, the network device may not send a CSI-RS, where the CSI resource is used by the terminal device associated with the network device to determine CSI.

As shown in fig. 5, an embodiment of the present application provides another communication method for flexibly configuring a CSI period of periodic CSI. It should be understood that the CSI period herein includes a CSI resource period and/or a CSI reporting period. The method may comprise the steps of:

s301: and the network equipment sends eighth information to the terminal equipment, wherein the eighth information is used for determining the first adjustment amount.

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

Accordingly, the terminal device receives the eighth information.

S302: and/or the terminal equipment determines the updated CSI reporting period according to the used CSI reporting period and the first adjustment quantity.

By adopting the method, the terminal equipment can adjust the CSI period only by indicating the adjustment amount in the process of adjusting the CSI period configuration, and does not need to reconfigure the CSI period, so that the cost can be saved, and the CSI period can be flexibly adjusted to save the power consumption of the terminal equipment.

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 periodicity by 5s.

Optionally, the eighth information may be used to indicate a second correspondence relationship, where the second correspondence relationship is a correspondence relationship between a moving speed and/or a moving state and an adjustment amount. The terminal device can thus determine the first adjustment amount corresponding to the movement speed and/or the mobility state of the terminal device.

The second correspondence is shown in table 2, for example.

Moving speed (meter/minute (m/min))	Mobility state	Adjustment quantity(s)
≤20	-	+5
20＜X≤200	-	-5
X＞200	-	-10
-	High mobility	-5
-	Low mobility	+5

TABLE 2

The above table 2 is only exemplary, and in practical use, the correspondence between a plurality of moving speeds and a plurality of time lengths may be used as a mapping table, and/or the correspondence between a plurality of moving states and a plurality of time lengths may be used as a mapping table, which is not limited in this application. In addition, the settings of the moving speed, the mobility state, and the duration in table 2 are only exemplary examples, and should not be construed as being limited thereto.

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

When the communication device is a terminal device, fig. 8 shows a simplified structural diagram of the terminal device. For easy understanding and illustration, in fig. 8, the terminal device is exemplified by a mobile phone. As shown in fig. 8, the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and an input-output device. The processor is mainly used for processing communication protocols and communication data, controlling the terminal equipment, executing software programs, processing data of the software programs and the like. The memory is used primarily for storing software programs and data. The radio frequency circuit is mainly used for converting baseband signals and radio frequency signals and processing the radio frequency signals. The antenna is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used for receiving data input by users and outputting data to the users. It should be noted that some kinds of terminal devices may not have input/output means.

When data needs to be sent, the processor performs baseband processing on the data to be sent and outputs baseband signals to the radio frequency circuit, and the radio frequency circuit performs radio frequency processing on the baseband signals and sends the radio frequency signals to the outside in the form of electromagnetic waves through the antenna. When data is transmitted to the terminal equipment, the radio frequency circuit receives radio frequency signals through the antenna, converts the radio frequency signals into baseband signals and outputs the baseband signals to the processor, and the processor converts the baseband signals into the data and processes the data. For ease of illustration, only one memory and processor are shown in FIG. 8. In an actual end device product, there may be one or more processors and one or more memories.

Alternatively, the transceiver module may also be referred to as a transceiver, a transceiver circuit, or a transceiver, etc., which may include at least one antenna 1111 and a radio frequency unit 1112. The RRU 1110 is mainly used for transceiving radio frequency signals and converting the radio frequency signals and baseband signals, for example, for sending indication information to a terminal device. The BBU 1120 is mainly used for performing baseband processing, controlling a base station, and the like. The RRU 1110 and the BBU 1120 may be physically disposed together or may be physically disposed separately, that is, distributed base stations.

The BBU 1120 also includes a memory 1121 and a processor 1122. The memory 1121 is used for storing necessary instructions and data. The processor 1122 is configured to control the base station to perform necessary actions, for example, to control the base station to perform the operation procedure related to the network device in the above method embodiment. The memory 1121 and processor 1122 may serve one or more boards. That is, the memory and processor may be provided separately on each board. Multiple boards may share the same memory and processor. In addition, each single board can be provided with necessary circuits.
