Description

Method and device for transmitting data and computer readable storage medium

Technical Field

The present application relates to the field of communications, and more particularly, to a method, apparatus, and computer-readable storage medium for transmitting data.

Background

In a mobile communication system, a large-scale multiple input multiple output (Massive MIMO) technology is used as one of key technologies of a new radio access technology (NR), and thus, system capacity can be improved by using more spatial degrees of freedom, which has been widely researched.

In a Massive MIMO system, a network device may send data to a terminal device through an antenna array composed of multiple transmit antennas, thereby improving the system throughput. In order to improve system transmission performance by performing precoding at the network device, the network device needs to acquire Channel State Information (CSI). The terminal device may generate a CSI report based on the CSI configuration information sent by the network device, and may report the CSI report to the network device.

When the CSI triggered by the network device exceeds the processing capability of the terminal device, in the existing standard, in the process of reporting the CSI report to the network device by the terminal device, how to select a partial CSI report from a plurality of CSI reports to be reported by the terminal device for updating is not defined.

Therefore, when the triggered CSI exceeds the processing capability of the terminal device, how the terminal device selects a partial CSI report from the multiple CSI reports to be reported to update becomes an urgent problem to be solved.

Disclosure of Invention

The application provides a method, equipment and a computer readable storage medium for transmitting data, wherein a terminal device can select a part of CSI reports from a plurality of CSI reports needing to be reported according to processing capacity to update so as to be adaptive to the processing capacity of the terminal device.

In a first aspect, a method for transmitting data is provided, the method comprising: the terminal equipment selects M CSI reports from the N CSI reports to update based on a preset rule, wherein N is a positive integer larger than 1, and M is a positive integer larger than or equal to 1 and smaller than or equal to N; the terminal device sends the N CSI reports to the network device, and the M CSI reports in the N CSI reports are updated.

It should be understood that the terminal device may select M CSI reports from the N CSI reports to update based on a preset rule, and may feed back the N CSI reports to the network device, where M CSI reports from the N CSI reports sent by the terminal device to the network device are updated, and the remaining (N-M) CSI reports may follow the CSI report reported by the terminal device to the network device before, which is not specifically limited in this application.

Optionally, in some embodiments, the CSI report may also be referred to as CSI report, CSI reporting, or CSI reporting setting, which is not specifically limited in this application.

The CSI report fed back by the terminal device to the network device in the embodiment of the present application may include, but is not limited to, at least one of the following information mentioned above: precoding matrix indicator PMI, rank indicator RI, channel quality indicator CQI, CSI-RS indication CRI information, stream indication LI information.

In this embodiment of the present application, the terminal device may update M CSI reports among the N CSI reports, and the terminal device may update the M CSI reports, which may be understood as the processing capability of the terminal device.

The embodiment of the present application does not specifically limit the specific implementation manner in which the terminal device can select M CSI reports from the N CSI reports for updating based on the preset rule. As an example, the terminal device may select M CSI reports from the N CSI reports for updating based on a rule that the update priority of the CSI report multiplexed with the uplink transmission data may be higher than that of the non-multiplexed CSI report. As another example, the terminal device may select M CSI reports from the N CSI reports to update based on a rule that the longer the CSI calculation time is, the higher the update priority of the CSI report may be. As another example, the terminal device may further select M CSI reports from the N CSI reports to update, by comprehensively considering the preset rule and the existing CSI priority rule.

In the embodiment of the present application, the time and the sequence for feeding back the N CSI reports by the terminal device are not specifically limited. As an example, the terminal device may feed back the CSI report to the network device after calculating a CSI that needs to be updated. As another example, the terminal device may further uniformly feed back the N CSI reports to the network device after calculating the M CSI that need to be updated.

The embodiment of the present application does not specifically limit the type of the CSI report fed back from the terminal device to the network device, and the CSI report may be a periodic CSI report, an aperiodic CSI report, or a semi-persistent CSI report.

In the above technical solution, the terminal device may select a part of CSI reports from the CSI reports to be reported according to the processing capability of the terminal device, and update the part of CSI reports so as to adapt to the processing capability of the terminal device.

In one possible implementation, the preset rule includes: the updating priority of the CSI report multiplexed with the uplink transmission data is higher than that of the non-multiplexed CSI report.

It should be understood that the network device may configure in advance a CSI report that is reported by multiplexing with uplink data sent by the terminal device. The CSI reports reported by multiplexing with the uplink data also need to occupy certain resources and calculation time, and when the terminal device can select M CSI reports from the N CSI reports to update, the CSI reports reported by multiplexing with the uplink data can be preferentially updated.

With reference to the first aspect, in a possible implementation manner, the preset rule includes: the longer the CSI computation time, the higher the update priority of the CSI report.

With reference to the first aspect, in a possible implementation manner, the more channel measurement resources CMR involved in calculating CSI, the higher the update priority of CSI reporting.

It should be understood that the more CMRs involved in calculating CSI, the more resources measured, and the longer the time to calculate CSI. For example, two types of codebooks are designed in NR, including: a type one (type I) single-panel codebook and a type two (type II) single-panel codebook. the type I codebook has the characteristics of low accuracy of characterizing the channel, but low feedback overhead, and is suitable for users with low signal processing capability. The type two (type II) single-panel codebook is a high-precision codebook with high cost, and is suitable for users with high signal processing capability.

Based on the priority rule, the priority of the type II codebook is higher than that of the type I codebook. The terminal device may prioritize updating the type II codebook in the process of selecting M CSI reports from the N CSI reports for updating.

With reference to the first aspect, in a possible implementation manner, the larger the feedback overhead is, the higher the update priority of the CSI report is.

It should be understood that the larger the feedback overhead, the longer the time to calculate CSI. The longer the terminal device calculates the CSI, the more information the terminal device can obtain, and the more accurate the obtained information.

It should be understood that the longer the CSI time calculation corresponding to a codebook type is, the priority may be given to updating the codebook type. The longer the terminal device calculates the CSI, the more information the terminal device can obtain, and the more accurate the obtained information.

With reference to the first aspect, in one possible implementation manner, the larger the trigger offset (triggering offset), the higher the update priority of the CSI report.

It should be understood that the network device may configure the terminal device with N CSI reporting configurations, which may configure the time and/or content at which the terminal device feeds back the N CSI reports. After receiving the N CSI reports, the terminal device may generate N CSI reports, and may report the N CSI reports to the network device.

It should be understood that the method of the network device side described in the second aspect corresponds to the method of the terminal device side described in the first aspect, and the method of the network device side may refer to the description of the terminal device side to avoid repetition, and the detailed description is appropriately omitted here.

Fig. 1 is a schematic diagram of a scenario of a communication system to which an embodiment of the present application is applicable. As shown in fig. 1, the communication system 100 includes a network device 102, and the network device 102 may include multiple antenna groups. Each antenna group can include multiple antennas, e.g., one antenna group can include

antennas

104 and 106, another antenna group can include

antennas

108 and 110, and an additional group can include

antennas

112 and 114. 2 antennas are shown in fig. 1 for each antenna group, however, more or fewer antennas may be utilized for each group. Network device 102 can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.

Network device 102 may communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it is understood that network device 102 may communicate with any number of terminal devices similar to

terminal devices

116 or 122.

End devices

116 and 122 may be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system 100.

As shown in fig. 1, terminal device 116 is in communication with

antennas

112 and 114, where

antennas

112 and 114 transmit information to terminal device 116 over forward link 118 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with

forward links

118 and 124. Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which a network device transmits through a single antenna to all its terminal devices.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

Furthermore, the communication system 100 may be a public land mobile network PLMN (public land mobile network) network or device-to-device (D2D) network or machine-to-machine (M2M) network or other networks, which is illustrated in fig. 1 for ease of understanding only and is a simplified schematic diagram, and other network devices may be included in the network, which are not shown in fig. 1.

The main function of the MIMO technology is to provide spatial diversity and spatial multiplexing gain, MIMO utilizes multiple transmitting antennas to transmit signals with the same information through different paths, and can obtain multiple independently fading signals of the same data symbol at a receiving end (e.g., a terminal device), thereby obtaining diversity-improved receiving reliability.

The precoding technique may utilize the known CSI to perform preprocessing on a transmission signal at a transmitting end (e.g., a network device), that is, to process the transmission signal by using a precoding matrix matched with a channel resource, so that the processed transmission signal can adapt to a channel environment, and can effectively suppress interference of multiple users in the MIMO system.

In order to obtain a precoding matrix that can be adapted to a channel, a transmitting end performs channel estimation in advance, usually by sending a reference signal, and obtains feedback from a receiving end, thereby determining a more accurate precoding matrix to perform precoding processing on data to be transmitted. As an example, the transmitting end may be a network device, the receiving end may be a terminal device, and the reference signal may be a reference signal used for downlink channel measurement, for example, a channel state information reference signal (CSI-RS). The terminal device may perform CSI measurement according to the received CSI-RS, and feed back CSI of the downlink channel to the network device. As another example, the sending end may also be a terminal device, the receiving end may be a network device, and the reference signal may be a reference signal used for uplink channel measurement, for example, a Sounding Reference Signal (SRS). The network device may perform CSI measurement according to the received SRS, and indicate CSI of the uplink channel to the terminal device. The CSI may include, for example, a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), and a Channel Quality Indicator (CQI), CSI-RS indicator (CRI) information, stream indicator (LI) information, and the like.

It should be understood that the communication method and the type of the reference signal applied to the reference signal in the present application are not particularly limited. For example, for downlink data transmission, the sending end may be, for example, a network device, the receiving end may be, for example, a terminal device, and the reference signal may be, for example, a channel state information reference signal (CSI-RS); for uplink data transmission, the sending end may be, for example, a terminal device, the receiving end may be, for example, a network device, and the reference signal may be, for example, a Sounding Reference Signal (SRS); for device to device (D2D) data transmission, the transmitting end may be, for example, a terminal device, the receiving end may also be, for example, a terminal device, and the reference signal may be, for example, an SRS.

As indicated above, in the process of reporting the CSI report to the network device, the terminal device cannot select a part of CSI reports from the CSI reports to be reported to update, so as to adapt to the processing capability of the terminal device.

For example, the network device may configure the terminal device with N CSI reporting configurations, which may configure the time and/or content at which the terminal device feeds back N CSI reports. After receiving the N CSI reports, the terminal device may generate N CSI reports, and may report the N CSI reports to the network device.

For example, if the current terminal device may have M unoccupied CSI processing units (that is, the terminal device may only update M CSI reports of N CSI reports, where M is a positive integer less than or equal to N), the terminal device may select M CSI reports from the N CSI reports for updating, and the rest CSI reports may continue to use the last CSI report. Finally, the terminal device may feed back the N CSI reports to the network device.

However, in the existing protocol, how to select M CSI reports from N CSI reports to be reported for updating by the terminal device is not specified, so as to adapt to the processing capability of the terminal device.

The embodiment of the application provides a data transmission method, and terminal equipment can select a part of CSI reports from a plurality of CSI reports needing to be reported according to processing capacity to update so as to be adaptive to the processing capacity of the terminal equipment. The following describes an embodiment of the present application in detail with reference to fig. 2.

Fig. 2 is a schematic flow chart of a method for transmitting data according to an embodiment of the present application. The method of FIG. 2 may include steps 210-220, and the steps 210-220 are described in detail below.

In step 210, the terminal device selects M CSI reports from the N CSI reports for updating based on a preset rule.

The terminal device may generate N CSI reports based on N CSI report configuration information sent by the network device, select M CSI reports from the N CSI reports based on a preset rule for updating, and feed back the N CSI reports to the network device, where N is a positive integer greater than 1, and M is a positive integer greater than or equal to 1 and less than or equal to N.

It should be understood that, M CSI reports in the N CSI reports sent by the terminal device to the network device are updated, and the remaining (N-M) CSI reports may follow the CSI report reported by the terminal device to the network device before, which is not specifically limited in this application.

In this embodiment of the present application, the terminal device may update M CSI reports among the N CSI reports, and the terminal device may update the M CSI reports, which may be understood as the processing capability of the terminal device. As an example, the terminal device has M unoccupied CSI processing units, and the terminal device may currently update M of the N CSI reports (that is, the terminal device may currently have processing capability to update M CSI reports).

The implementation manner of step 210 may be various, and this is not specifically limited in this embodiment of the present application. As an example, the terminal device may select M CSI reports from the N CSI reports for updating based on a rule that the update priority of the CSI report multiplexed with the uplink transmission data may be higher than that of the non-multiplexed CSI report. As another example, the terminal device may select M CSI reports from the N CSI reports to update based on a rule that the longer the CSI calculation time is, the higher the update priority of the CSI report may be. As another example, the terminal device may further select M CSI reports from the N CSI reports to update, by comprehensively considering the preset rule and the existing CSI priority rule. The following detailed description will be made in conjunction with specific embodiments, which are not repeated herein.

Optionally, in some embodiments, the CSI report may also be CSI report, CSI reporting, or CSI reporting setting, which is not specifically limited in this application.

In step 220, the terminal device sends the N CSI reports to a network device.

The terminal device may select M CSI reports from the N CSI reports based on a preset rule to update, and may feed back the N CSI reports to the network device. Wherein, M CSI reports among the N CSI reports fed back to the network device may be updated.

The network device will generally instruct the terminal device in advance how to feed back the CSI report, such as, but not limited to, time for feeding back the CSI report (e.g., but not limited to, a slot (slot) or a subframe (subframe)), bearer resources for the CSI report, and the like, where the feedback time and the bearer resources for different CSI reports may be the same or different. For details of related art related to feedback CSI reporting, reference may be made to the prior art, and details are not repeated herein. The terminal device may feed back the N CSI reports according to the indication of the network device. In the embodiment of the application, the terminal device may select a part of CSI reports from the CSI reports that need to be reported to update, so as to adapt to the processing capability of the terminal device.

The embodiment of the present application does not specifically limit the type of the CSI report fed back by the terminal device to the network device. As one example, periodic CSI reports (periodic-CSI reports) feedback may be provided. For example, in the periodic CSI report feedback, the network device may configure a periodic Physical Uplink Control Channel (PUCCH), and the terminal device may report the CSI report periodically on the configured PUCCH resource. As another example, aperiodic-CSI reports (aperiodic-CSI reports) feedback may be possible. For example, in aperiodic CSI report feedback, a network device may trigger a terminal device to perform CSI report feedback through Downlink Control Information (DCI), and the terminal device may perform CSI report feedback on a Physical Uplink Shared Channel (PUSCH) in a corresponding uplink subframe of a trigger subframe.

Optionally, in some embodiments, the terminal device may select M CSI reports from the N CSI reports to update based on the following priority rules: the updating priority of the CSI report multiplexed with the uplink transmission data is higher than that of the non-multiplexed CSI report.

It should be understood that the network device may configure in advance a CSI report that is reported by multiplexing with uplink data sent by the terminal device. The CSI reports reported by multiplexing with the uplink data also need to occupy certain resources and calculation time, and when the terminal device can select M CSI reports from the N CSI reports to update, the CSI reports reported by multiplexing with the uplink data can be preferentially updated. In a specific implementation process, the CSI report multiplexed with the uplink transmission data may be understood as a CSI report transmitted together with the uplink data, where such CSI report is typically transmitted through a PUSCH, and the PUSCH is typically used for carrying the uplink data. Generally, uplink data transmission of a terminal device is scheduled by a network device.

In the embodiment of the application, the terminal device can preferentially consider updating the CSI report reported by multiplexing with the uplink data, and the terminal device can process the CSI report which needs to be multiplexed with the uplink data and is configured by the network device in a limited processing capacity, so as to avoid that the configured CSI report which needs to be multiplexed with the uplink data is not updated and reported.

Optionally, in some embodiments, the terminal device may select M CSI reports from the N CSI reports to update based on the following priority rules: the longer the CSI computation time, the higher the update priority of the CSI report.

It should be understood that the longer the terminal device calculates CSI, the more information the terminal device can obtain, and the more accurate the obtained information. Therefore, when the terminal device selects M CSI reports from the N CSI reports to update, the CSI report with a longer CSI calculation time in the N CSI reports may be preferentially updated.

For example, the network device configures a CSI computation time of 5ms to the terminal device, and the terminal device may feed back a CSI report to the network device after 5 ms. If the network device configures the terminal device to feed back the CSI report to the network device after 1ms, the network device may acquire less channel state information of the terminal device. If the network device configures the terminal device to feed back the CSI report to the network device after 4ms, the channel state information of the terminal device obtained by the network device may be more and more accurate. It should be noted that in the implementation, the CSI calculation time may be embodied as other types of parameters that can be used to measure the accuracy of CSI, such as, but not limited to, measurement resources, update feedback overhead, update codebook type and update trigger offset, which will be described below.

In the embodiment of the application, the terminal device may preferentially consider updating the CSI reports with longer calculation time in the N CSI reports, and the terminal device may feed back more and/or more accurate information to the network device within the limited processing capability.

In the embodiment of the present application, the terminal device preferentially considers various specific implementation manners of updating M CSI reports with a longer CSI calculation time among the N CSI reports, which is not specifically limited in the present application. As an example, the terminal device may prioritize CSI reports with more measurement resources involved in updating the CSI, where the measurement resources may be, for example and without limitation, Channel Measurement Resources (CMRs) and/or Interference Measurement Resources (IMRs). As another example, the terminal device may prioritize CSI reports with higher update feedback overhead. As another example, the terminal device may prioritize the CSI report with a longer CSI computation time corresponding to the updated codebook type. As another example, the terminal device may prioritize CSI reports with larger update trigger offsets (triggering offsets).

The following describes a CSI report, which is an example in which a terminal device can prioritize a CSI update and calculate a CSI with a large number of CMRs. The channel measurement resource may be, for example, a CSI-RS resource for performing channel measurement, and may also be an interference measurement resource, or both of the above resources may be considered simultaneously, or another form of measurement resource. The more resources measured when calculating the CSI, the longer the terminal device can calculate the CSI. The more information the terminal device can acquire, the more accurate the acquired information.

The following describes in detail an example in which the terminal device can prioritize a CSI report with a large update feedback overhead. The larger the feedback overhead, the longer the time to calculate CSI. The more information the terminal device can acquire, the more accurate the acquired information.

For example, two types of codebooks are designed in NR, including: a type one (type I) single-panel codebook and a type two (type II) single-panel codebook. The CSI report determined based on the type I codebook has the characteristics of low accuracy of the characterized channel, low feedback overhead and suitability for users with low signal processing capability. The channel characterized by the CSI report determined based on the type II codebook has high accuracy, but the feedback overhead is high, so that the method is suitable for users with high signal processing capability.

Based on the above priority rule, the priority of the CSI report determined based on the type II codebook is higher than the priority of the CSI report determined based on the type I codebook. The terminal device may prioritize updating the CSI report determined based on the type II codebook in the process of selecting M CSI reports from the N CSI reports for updating.

The following describes in detail a CSI report in which the terminal device can preferentially consider a longer CSI calculation time corresponding to an update codebook type. The longer the CSI time corresponding to the codebook type is calculated, the priority may be given to updating the codebook type. The longer the terminal device calculates the CSI, the more information the terminal device can obtain, and the more accurate the obtained information.

The following describes in detail by taking an example that the terminal device can preferentially consider a CSI report with a large update trigger offset (triggering offset). The larger the trigger offset, the longer the time to compute the CSI. The longer the terminal device calculates the CSI, the more information the terminal device can obtain, and the more accurate the obtained information.

Optionally, in some embodiments, the terminal device may combine at least one of the foregoing priority rules with an existing CSI priority, and select M CSI reports from the N CSI reports to update. These prioritization rules, such as but not limited to the prioritization rules mentioned herein, and prioritization rules mentioned in the prior art, may be combined in any combination as desired. For example, the priority of each CSI report may be calculated according to a calculation formula, and M CSI reports with the top priority may be selected for updating. The calculation formula may include a plurality of parameters, each parameter is associated with a technical characteristic, and the technical characteristic may be, for example and without limitation, whether the CSI report is multiplexed with uplink transmission data, a CSI calculation time, or a technical characteristic associated with an existing CSI priority rule. Also, the contribution of different technical characteristics in determining CSI reporting priorities may differ, i.e. the weights of the parameters may differ. For example, the weight of the parameter of whether to multiplex with the uplink transmission data may be higher than the weight of the parameter of the calculation time of the CSI, that is, when determining the priority of the CSI report, the parameter of whether to multiplex with the uplink transmission data is more important than the parameter of the calculation time of the CSI. It should be noted that the rule specified by each priority rule should be understood as how to determine the CSI report to be preferentially updated according to the priority rule in the case where the priorities of the multiple CSI reports determined based on the other priority rules are the same. When the priority updated CSI is determined in combination with a plurality of priority rules, there may be a case where the finally determined priority updated CSI report does not satisfy at least one priority rule because the final priority is calculated based on a combination of the plurality of priority rules, not solely based on the at least one priority rule.

As an example, the rule that the update priority of the CSI report multiplexed with the uplink transmission data may be higher than that of the non-multiplexed CSI report may be combined with the existing CSI priority formula to select M CSI reports from the N CSI reports for updating. As another example, the rule that the longer the CSI calculation time is, the higher the update priority of the CSI report may be combined with the existing CSI priority formula to select M CSI reports from the N CSI reports for updating may be used. As another example, the rule that the update priority of the CSI report multiplexed with the uplink transmission data may be higher than the rule of the non-multiplexed CSI report, and the longer the CSI calculation time is, the higher the update priority of the CSI report may be, may be combined with the existing CSI priority formula to select M CSI reports from the N CSI reports for updating.

The existing CSI priority formula is as follows:

Pri_iCS(y，k，c，s)＝2×16×M_s×y+16×M_s×y+M_s×c+2

wherein y-0 may be used to indicate that aperiodic CSI reports are fed back on PUSCH; y ═ 1 can be used to represent a semi-persistent CSI report fed back on PUSCH; y-2 may be used to represent feedback of semi-persistent CSI reports on PUCCH; y-3 may be used to represent a periodic CSI report fed back on PUSCH;

k-0 may be used to represent that the CSI report carries L1-Reference Signal Receiving Power (RSRP); k-1 may be used to indicate that the CSI report does not carry L1-RSRP;

c may be used to represent an index of a serving cell;

s may be used to represent a report configuration ID;

M_smay be used to represent the maximum value of the upper layer LI parameter in the CSI report.

It should be understood that the existing CSI priority formulas mentioned above may be used to represent the update priority level of the CSI report.
