This application claims the priority of the Chinese Patent Application filed on May 11, 2018, the Chinese Patent Office, Application No. 201101447325.2, entitled "A Method, Apparatus, and Computer Readable Storage Media for Data Transmission", the entire contents of which is incorporated herein by reference. This is incorporated herein by reference.

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 technique

In mobile communication systems, massive multiple input multiple output (Massive MIMO) technology is one of the key technologies of the new radio access technology (NR), which can utilize more space. Freedom increases system capacity and has been extensively studied.

In a Massive MIMO system, a network device can transmit data to an end device through an antenna array composed of a plurality of transmitting antennas, thereby improving system throughput. In order to improve system transmission performance by performing precoding on a network device, the network device needs to know channel state information (CSI). The terminal device may generate a CSI report based on the CSI configuration information sent by the network device, and 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, during the process of reporting the CSI report to the network device by the terminal device, there is no definition of how the terminal device selects a partial CSI report from multiple CSI reports that need to be reported.

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

M is a positive integer greater than or equal to 1 and less than or equal to N; the terminal device sends the N CSI reports to the network device, and the M CSI reports are updated in the N CSI reports.

It should be understood that the terminal device may select M CSI reports from the N CSI reports for updating according to a preset rule, and may feed back N CSI reports to the network device, where the terminal device sends the N CSI reports to the network device. There are M CSI reports that have been updated. The remaining (NM) CSI reports can be used to report the CSI report to the network device before the terminal device. This application does not specifically limit this.

FIG. 1 is a schematic diagram of a scenario of a communication system applicable to an embodiment of the present application. As shown in FIG. 1, the communication system 100 includes a network device 102, which may include multiple antenna groups. Each antenna group may include multiple antennas, for example, one antenna group may include antennas 104 and 106, another antenna group may include antennas 106 and 110, and an additional group may include antennas 112 and 114. Two antennas are shown in Figure 1 for each antenna group, although more or fewer antennas may be used for each group. Network device 102 may additionally include a transmitter chain and a receiver chain, as will be understood by those of ordinary skill in the art, which may include multiple components related to signal transmission and reception (eg, processor, modulator, multiplexer, solution) Tuner, demultiplexer or antenna, etc.).

Network device 102 can communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it will be appreciated that network device 102 can communicate with any number of terminal devices similar to terminal device 116 or 122. Terminal devices 116 and 122 may be, for example, cellular telephones, smart phones, portable computers, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable for communicating over wireless communication system 100. device.

As shown in FIG. 1, terminal device 116 is in communication with antennas 112 and 114, wherein antennas 112 and 114 transmit information to terminal device 116 over forward link 116 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with antennas 104 and 106, wherein antennas 104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

For example, in a frequency division duplex (FDD) system, for example, the forward link 116 can utilize a different frequency band than that used by the reverse link 120, and the forward link 124 can utilize the reverse link. 126 different frequency bands used.

As another example, in a time division duplex (TDD) system and a full duplex system, the forward link 116 and the reverse link 120 can use a common frequency band, a forward link 124, and a reverse link. Link 126 can use a common frequency band.

Each set of antennas and/or regions designed for communication is referred to as a sector of network device 102. For example, the antenna group can be designed to communicate with terminal devices in sectors of the network device 102 coverage area. In the process in which network device 102 communicates with terminal devices 116 and 122 via forward links 116 and 124, respectively, the transmit antennas of network device 102 may utilize beamforming to improve the signal to noise ratio of forward links 116 and 124. In addition, when the network device 102 uses beamforming to transmit signals to the randomly dispersed terminal devices 116 and 122 in the relevant coverage area, the network device 102 uses a single antenna to transmit signals to all of its terminal devices. Mobile devices are subject to less interference.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting device and/or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device can encode the data for transmission. In particular, the wireless communication transmitting device may acquire (eg, generate, receive from other communication devices, or store in memory, etc.) a certain number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be included in a transport block (or multiple transport blocks) of data that may be segmented to produce multiple code blocks.

In addition, the communication system 100 may be a public land mobile network PLMN network or a device to device (D2D) network or a machine to machine (M2M) network or other network, and FIG. 1 is merely an example for convenience of understanding. A simplified schematic diagram of the network may also include other network devices, which are not shown in FIG.

The main function of MIMO technology is to provide spatial diversity and spatial multiplexing gain. MIMO uses multiple transmit antennas to transmit signals with the same information through different paths, and at the receiving end (for example, terminal equipment) can acquire the same data symbol. Multiple independent fading signals, resulting in improved reception reliability for diversity.

The precoding technique can use the known channel state information CSI to preprocess the transmitted signal at the transmitting end (for example, the network device), that is, to process the transmitted signal by using a precoding matrix matched with the channel resource, so that the processed signal is processed. The transmitted signal can adapt to the channel environment and can effectively suppress multiple user interference in the MIMO system.

In order to obtain a precoding matrix that can be adapted to the channel, the transmitting end generally performs channel estimation by transmitting a reference signal, and obtains feedback of the receiving end, thereby determining a relatively accurate precoding matrix to perform precoding processing on the data to be transmitted. . As an example, the transmitting end may be a network device, and 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 the CSI of the downlink channel to the network device. As another example, the transmitting end may also be a terminal device, and 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 the CSI of the uplink channel to the terminal device. The CSI may include, for example, a precoding matrix indicator (PMI), a rank indication (RI), and a channel quality indicator (CQI), and a CSI-RS indicator (CSI-RS indicator, CRI). ) information, layer indicator (LI) information, and the like.

It should be understood that the communication method to which the reference signal is applied and the type of the reference signal are not particularly limited. For example, for the downlink data transmission, the transmitting end may be, for example, a network device, and 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 example, the transmitting end may be a terminal device, and the receiving end may be, for example, a network device, and the reference signal may be, for example, a sounding reference signal (SRS); and a device to device (D2D) data transmission. The transmitting end can be, for example, a terminal device, and the receiving end can also be a terminal device, for example, the reference signal can be, for example, an SRS.

The above indicates that in the process of reporting the CSI report to the network device, the terminal device cannot select a partial CSI report to be updated from multiple CSI reports that need to be reported, so as to be compatible with its processing capability.

For example, the network device can configure N CSI report configurations to the terminal device, and the CSI report configuration can configure the time and/or content of the N CSI reports that the terminal device feeds back. After receiving the N CSI report configurations, the terminal device may generate N CSI reports, and report the N CSI reports to the network device.

For example, if the current terminal device can have M unoccupied CSI processing units (that is, currently the terminal device can only update M CSI reports in N CSI reports, 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 remaining CSI reports may inherit the CSI report of the last transmission. Finally, the terminal device can feed back the N CSI reports to the network device.

In the existing protocol, there is no provision for how the terminal device selects M CSI reports from the N CSI reports that need to be reported for updating, so as to be compatible with its processing capability.

The embodiment of the present application provides a method for transmitting data, and the terminal device may select, according to the processing capability, a partial CSI report from a plurality of CSI reports that need to be reported to be updated, so as to be adapted to its processing capability. The embodiments of the present application are described in detail below with reference to FIG. 2 .

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

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

The terminal device may generate N CSI reports based on the N CSI report configuration information sent by the network device, where the terminal device may select M CSI reports from the N CSI reports to update according to a preset rule, and may report N CSI reports. Feedback 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 are updated in the N CSI reports sent by the terminal device to the network device, and the remaining (NM) CSI reports may use the CSI report reported to the network device before the terminal device is used. No specific restrictions.

The CSI report that the terminal device feeds back to the network device in this embodiment may include, but is not limited to, at least one of the following information: precoding matrix indication PMI, rank indication RI, channel quality indicator CQI, CSI-RS Indicates CRI information, flow indication LI information.

In the embodiment of the present application, the terminal device may update the M CSI reports in the N CSI reports, and the terminal device may update the M CSI reports to 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 update M CSI reports in the N CSI reports (that is, the current processing capability of the terminal device may be an update M. CSI reports).

The implementation of the step 210 may be various. The embodiment of the present application does not specifically limit this. As an example, the terminal device may select, based on the rule of the non-multiplexed CSI report, that the update priority of the CSI report multiplexed with the uplink transmission data may be updated from the N CSI reports. As another example, the terminal device may select, based on the CSI calculation time, a rule that the update priority of the CSI report may be higher, and select M CSI reports from the N CSI reports for updating. As another example, the terminal device may further select, according to the foregoing preset rule and the existing CSI priority rule, M CSI reports from the N CSI reports for updating. The detailed description will be made in detail below with reference to specific embodiments, and details are not described herein.

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

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

The terminal device may select M CSI reports from the N CSI reports for updating according to a preset rule, and may feed back the N CSI reports to the network device. Among them, M CSI reports may be updated in the N CSI reports fed back to the network device.

The network device usually indicates in advance how the terminal device feeds back the CSI report, such as, but not limited to, the time when the CSI report is fed back (for example, but not limited to, a slot or a subframe), the bearer resource of the CSI report, etc., different. The feedback time and bearer resources of the CSI report may be the same or different. For related technical details of the feedback CSI report, reference may be made to the prior art, and details are not described herein. The terminal device may feed back the above N CSI reports according to the indication of the network device. In the embodiment of the present application, the terminal device may select a part of the CSI report to be updated from multiple CSI reports that need to be reported, so as to be compatible with its processing capability.

The embodiment of the present application does not specifically limit the type of the CSI report that the terminal device feeds back to the network device. As an example, it may be a periodic CSI report (periodic-CSI reports) feedback. 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 periodically report the CSI report on the configured PUCCH resource. As another example, it may be aperiodic-CSI reports. For example, in the non-periodic CSI report feedback, the network device may trigger the terminal device to perform CSI report feedback by using downlink control information (DCI), where the terminal device may trigger the physical in the corresponding uplink subframe of the subframe. CSI report feedback is performed on the uplink shared channel (PUSCH).

Optionally, in some embodiments, the terminal device may select, according to the following priority rule, the M CSI reports from the N CSI reports to be updated: the CSI report multiplexed with the uplink transmission data has a higher update priority than the non-review Used CSI report.

It should be understood that the network device may configure the CSI report reported by multiplexing with the uplink data sent by the terminal device in advance. The CSI report reported by multiplexing with the uplink data also needs to occupy a certain resource and calculation time. When the terminal device can select M CSI reports from the N CSI reports for updating, the priority data can be preferentially updated and multiplexed with the uplink data. Reported CSI report. In a specific implementation process, the CSI report that is multiplexed with the uplink transmission data can be understood as a CSI report that is transmitted together with the uplink data. The CSI report is usually transmitted through the PUSCH, and the PUSCH is usually used to carry the uplink data. Generally, the uplink data transmission of the terminal device is scheduled by the network device.

In the embodiment of the present application, the terminal device may preferentially update the CSI report that is reported and multiplexed by the uplink data, and the terminal device may process the CSI configured by the network device to be multiplexed with the uplink data within a limited processing capability. The report does not update the CSI report that needs to be multiplexed with the upstream data.

Optionally, in some embodiments, the terminal device may select, according to the following priority rule, the M CSI reports from the N CSI reports to be updated: the longer the CSI calculation time, the higher the update priority of the CSI report.

It should be understood that the longer the terminal device calculates the CSI, the more information the terminal device can acquire, and the more accurate the acquired information. Therefore, when the terminal device selects M CSI reports from the N CSI reports for updating, the CSI report with a long CSI calculation time in the N CSI reports may be preferentially considered.

For example, the network device configures a CSI calculation time to the terminal device for 5 ms, and the terminal device can feed back the 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 1 ms, the channel state information of the terminal device acquired by the network device may be less. If the network device configures the terminal device to feed back the CSI report to the network device after 4 ms, the channel state information of the terminal device acquired by the network device may be more and more accurate. It should be noted that in a specific implementation process, the CSI calculation time may be embodied as other forms of parameters that may be used to measure the accuracy of the CSI, such as, but not limited to, measurement resources, update feedback overhead, update codebook types, and Update trigger offsets, etc.

In the embodiment of the present application, the terminal device may preferentially update the CSI report with a long calculation time in the N CSI reports, and the terminal device may feed more and/or more accurate information to the network within a limited processing capability. device.

In the embodiment of the present application, there are various implementation manners for the terminal device to preferentially update the M CSI reports with a long CSI calculation time in the N CSI reports, which is not specifically limited in this application. As an example, the terminal device may preferentially update the CSI report with more measurement resources involved in calculating the CSI, where the measurement resource may be, for example but not limited to, channel measurement resources (CMR) and/or interference. Interference measurement resources (IMR). As another example, the terminal device may prioritize updating the CSI report with a large feedback overhead. As another example, the terminal device may preferentially consider the CSI report with a longer CSI calculation time corresponding to the update codebook type. As another example, the terminal device may prioritize updating the CSI report with a larger triggering offset.

In the following, a detailed description will be given by taking an example in which the terminal device can preferentially update the CSI report with more CMR involved in calculating the CSI. The channel measurement resource may be, for example, a CSI-RS resource for performing channel measurement, or may be an interference measurement resource, or both of the above resources, or other forms of measurement resources. The more resources are measured when calculating CSI, the longer the terminal device calculates CSI. The more information the terminal device can acquire, the more accurate the information obtained.

The following is a detailed description of the CSI report in which the terminal device can preferentially update the feedback overhead. The larger the feedback overhead, the longer the CSI is calculated. The more information a terminal device can acquire, the more accurate the information obtained.

For example, two types of codebooks are designed in NR, including: type I single panel codebook and type II single panel codebook. The accuracy of the channel characterized by the CSI report determined based on the type I codebook is relatively low, but has the characteristics of low feedback overhead, and is suitable for users with low signal processing capability. The accuracy of the channel represented by the CSI report determined by the type II codebook is relatively high, but the feedback overhead is large, and is suitable for users with relatively high signal processing capability.

Based on the above prioritization rules, the CSI report determined based on the type II codebook has a higher priority than the CSI report determined based on the type I codebook. The terminal device may preferentially update the CSI report determined based on the type II codebook during the process of selecting M CSI reports for updating from the N CSI reports.

The CSI report with the longer CSI calculation time corresponding to the update codebook type is taken as an example for detailed description. The longer the CSI time calculation corresponding to the codebook type, the priority can be given to updating the codebook type. The longer the terminal device calculates the CSI, the more information the terminal device can acquire, and the more accurate the acquired information.

In the following, a detailed description will be given by taking an example in which the terminal device can preferentially update the CSI report with a larger triggering offset. The larger the trigger offset, the longer the CSI is calculated. The longer the terminal device calculates the CSI, the more information the terminal device can acquire, and the more accurate the acquired 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 for updating. These prioritized rules, such as but not limited to the prioritized rules mentioned herein, and the prioritized rules mentioned in the prior art, can be arbitrarily combined as desired. For example, the priority of each CSI report can be calculated according to a calculation formula, and the M CSI reports with the highest priority are selected for updating. The calculation formula may include multiple parameters, and each parameter is associated with a technical characteristic, such as, but not limited to, whether the CSI report is multiplexed with uplink transmission data, CSI calculation time, or Technical characteristics associated with existing CSI priority rules, etc. At the same time, the contribution of different technical characteristics in determining the priority of CSI reports may be different, that is, the weight of the parameters may be different. For example, whether the parameter of multiplexing with the uplink transmission data may be higher than the weight of the calculation time of the CSI, that is, whether the parameter is multiplexed with the uplink transmission data when determining the priority of the CSI report. The CSI calculation time parameter is more important. It should be noted that the rules specified by each of the priority rules should be understood as how to prioritize the updated CSI reports based on the priority rules in the case where the priorities of the plurality of CSI reports determined based on other priority rules are the same. When the priority update CSI is determined in combination with a plurality of priority rules, there may be a case where the finally determined priority update CSI report does not satisfy at least one priority rule, because the final priority is calculated based on a plurality of priority rules. , not just based on at least one of the priority rules described above.

It should be understood that the terminal device may combine at least one of the following priority rules with the existing CSI priority, and may select M CSI reports from the N CSI reports for updating: CSI report multiplexed with the uplink transmission data. The update priority may be higher than the non-multiplexed CSI report, and the longer the CSI calculation time, the higher the update priority of the CSI report may be.

As an example, the update priority of the CSI report multiplexed with the uplink transmission data may be higher than the non-multiplexed CSI report rule and the existing CSI priority formula may be selected from the N CSI reports. The CSI report is updated. As another example, the longer the CSI calculation time, the higher the update priority of the CSI report can be combined with the existing CSI priority formula to select M CSI reports from the N CSI reports for updating. As another example, 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, the higher the update priority of the CSI report may be. The rules are 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 iCSI (y, k, c} , s) = 2 × 16 × M s × y + 16 × M s × y + M s × c + s

Where y=0 can be used to indicate that a non-periodic CSI report is fed back on the PUSCH; y=1 can be used to indicate that a semi-persistent CSI report is fed back on the PUSCH; y=2 can be used to indicate A semi-persistent CSI report is fed back on the PUCCH; y=3 can be used to indicate that a periodic CSI report is fed back on the PUSCH;

k=0 can be used to indicate that the CSI report carries L1-reference signal receiving power (RSRP); k=1 can be used to indicate that the CSI report does not carry the L1-RSRP;

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

s can be used to represent the report configuration ID;

M _s can be used to represent the maximum value of the upper LI parameters in the CSI report.

It should be understood that the existing CSI priority formula mentioned above can be used to indicate the update priority level of the CSI report.
