Description

Reference signal processing method, reference signal processing device, information configuration method, information configuration device, terminal and base station

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for reference signal processing and information configuration, a terminal, and a base station.

Background

The ultra-wide bandwidth high frequency band, i.e. millimeter wave communication, becomes an important direction for the development of future mobile communication, and especially, when increasingly congested spectrum resources and physical networks are accessed in large quantities, the advantages of millimeter waves become more and more attractive. High-band communication, by virtue of its large bandwidth, will become an important innovation point of New Radio access technology (NR) of 5G.

However, high-frequency communication has the defects of link attenuation, such as large propagation path loss, large air (especially oxygen) absorption and heavy rain attenuation. In view of the above drawbacks, the high-band communication system can obtain high antenna gain and countermeasure signal transmission loss through a multi-antenna array and a beamforming scheme by using the characteristics of short high-band wavelength, easy antenna integration, and the like, thereby ensuring link margin and improving communication robustness. Generally, both the transmitting end and the receiving end need to obtain a large array gain through beamforming.

In the process of training the antenna weight (also called precoding and beam), a transmitting end transmits a reference signal, and a receiving end receives the reference signal and performs measurement. The Receiving end determines a Reference Signal resource corresponding to the best precoding for transmission and reception based on measurement of a Reference Signal, for example, Reference Signal Receiving Power (RSRP), and feeds back a selected Reference Signal resource indicator (CRI) to the transmitting end in a CSI-RS resource indicator (CRI) feedback manner. The reference signal resources include reference signal time-frequency domain resources, sequence resources, port resources, and the like.

In the process of configuring the reference signal resource by the transmitting end, some configuration modes are required to be used for facilitating the measurement of the transmitting precoding and the receiving precoding by the receiving end, for example, the repetition of the reference signal resource in the time domain is configured to perform the measurement of the receiving precoding, and in the related art, the measurement of the receiving precoding by using the repetition information configuration cannot be well supported. In the process of indicating feedback of Channel State Information (CSI for short) by a reference signal resource at a receiving end, some reference signal resources are redundant Information for feedback, for example, the reference signal resources configured at the transmitting end for receiving precoding measurement, so that unnecessary feedback overhead is brought in the feedback process of the related art.

In view of the above technical problems in the related art, no effective solution has been proposed at present.

In this embodiment, a reference signal processing method operating in the mobile terminal is provided, and fig. 2 is a flowchart of the reference signal processing method according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:

step S202, obtaining configuration information of a reference signal resource set and a first indication parameter corresponding to the reference signal resource set; wherein the configuration information of the reference signal resource set includes: reference signal resources included in the set of reference signal resources; the first indication parameter is used for indicating whether the reference signal resources contained in the reference signal resource set are repeated;

step S204, processing the reference signal according to the configuration information of the reference signal resource set and the first indication parameter; wherein processing the reference signal comprises at least one of: and measuring the reference signal and determining whether to report the reference signal resource indication.

Through the steps, the configuration information of the reference signal resource set and the first indication parameter corresponding to the reference signal resource set are obtained, so that the reference signal can be measured and/or the reference signal resource indication can be reported through the configuration information of the reference signal resource set and the first indication parameter, the repeated reference signal resources can be made to adopt the same feedback through the obtained first indication parameter, the problem that the feedback overhead is large due to the configuration of the reference signal and the feedback mode of the channel state information in the related technology can be solved, and the effect of reducing the feedback overhead is achieved.

In an embodiment of the present invention, the step S204 may be expressed in various forms, and in an embodiment of the present invention, the step S204 may be expressed as: when the reference signal resource sets are multiple and a first indication parameter corresponding to each reference signal resource set is a first designated value, reporting a reference signal resource set indication; when the first indication parameter is a first designated value, the first indication parameter is used for indicating the repetition of the reference signal resources contained in the reference signal resource set.

In an embodiment of the present invention, the step S204 may be represented as: when the reference signal resource set is one and a first indication parameter of the reference signal resource set is a first specified value, not reporting reference signal resource indication information and reference signal resource set indication; when the reference signal resource set is one and the first indication parameter of the reference signal resource set is a second specified value, reporting a reference signal resource indication; when the first indication parameter is a first designated value, the first indication parameter is used for indicating the repetition of the reference signal resources contained in the reference signal resource set; when the first indication parameter is the second indication value, the first indication parameter is used for indicating that the reference signal resources contained in the reference signal resource set are not repeated.

In an embodiment of the present invention, the step S204 may be represented as: when the reference signal resource sets are multiple, the number of the reference signal resources included in each reference signal resource set is the same, the second indication parameter is a first specified value, and the first indication parameter corresponding to each reference signal resource set is a second specified value, reporting a reference signal resource indication; wherein the second indication parameter is used for indicating whether reference signal resources at the same position in the multiple reference signal resource sets are repeated or not; when the first indication parameter is a second indication value, the first indication parameter is used for indicating that the reference signal resources contained in the reference signal resource set are not repeated; the second indicator parameter is used to indicate a reference signal resource repetition at a same position within the plurality of reference signal resource sets when the second indicator parameter is the first specified value.

The first designated value may be "ON" or another value, but is not limited thereto, and the second designated value may be "OFF" or another value, but is not limited thereto.

It should be noted that, before reporting the reference signal resource indication, the method may further include: and determining the value of the second indication parameter according to the second configuration information of the base station and/or the agreement with the base station.

It should be noted that reporting the reference signal resource indication may be represented as: aiming at a reference signal resource set, one reference signal resource set comprises M reference signal resources, and aiming at the reference signal resources needing to be reported, reference signal resource indications corresponding to the reference signal resources needing to be reported are reported according to codes of the reference signal resources needing to be reported in the reference signal resource set; wherein M is an integer greater than or equal to 1.

It should be noted that, the reference signal resource to be reported is encoded by at least one of the following methods: coding according to the configuration sequence of the reference signal resources needing to be reported in the reference signal resource set; and coding according to the sequence of the size of the identifier of the reference signal resource needing to be reported in the reference signal resource set.

For example, there are 8 total reference signal resources from 0 to 7, one reference signal resource set includes four reference signal resources {0,3,4,7}, and the terminal selects the 4 th reference signal resource to report, that is, the reference signal resource 7 feeds back; if the reference signal resource indicates that the local coding is not restricted to the set of reference signal resources, then it is reference signal resource 7 that is fed back, requiring 3 bits of quantization (indicating one of 0-7); if the reference signal resource indication is a local code restricted to a set of reference resources, then the 4 th reference signal resource is fed back, requiring only 2 bits of quantization (indicating one of 0-3).

Under the framework described above, it represents two ways: for example, in order to indicate the reference signal resource 7 in the reference signal set, the value fed back by the terminal is 3, which is the reference signal resource ordered as 4 in the reference signal resource set; another is to perform local coding according to the size of the reference signal resource ID, for example, in the above example, the value fed back by the terminal is 0, which refers to the reference signal resource with the 1 st size of the reference signal resource ID in the reference signal resource set.

In an embodiment of the present invention, the method may further include at least one of: when the first indication parameter is a first designated value, reference signal resources contained in a reference signal resource set corresponding to the first indication parameter are time division multiplexed; when the first indication parameter is a first designated value, the reference signal resources contained in the reference signal resource set corresponding to the first indication parameter are quasi co-located with respect to the spatial reception parameter; when the first indication parameter is a first designated value, the interval of the reference signal resources adjacent to the reference signal resource set in the time domain corresponding to the first indication parameter in the time domain meets a preset condition; when the first indication parameter is a first designated value, resource unit mapping patterns of reference signal resources contained in a reference signal resource set corresponding to the first indication parameter on a frequency domain are the same; when the first indication parameter is a first designated value, the first indication parameter is used for indicating the repetition of the reference signal resources contained in the reference signal resource set.

The predetermined condition is related to the terminal capability information.

In one embodiment of the present invention, in the case that the reference signal is a tracking reference signal, acquiring the first indication parameter may be represented as: determining a first indication parameter according to first configuration information of the base station or an agreement with the base station; the reference signal resource set is a tracking reference signal resource set, and when the first indication parameter is a first specified value, the first indication parameter is used for indicating the repetition of the tracking reference signal resource contained in the tracking reference signal resource set.

It should be noted that the tracking reference signal resources included in the tracking reference signal resource set are time division multiplexed or frequency division multiplexed.

It should be noted that, in the case that the tracking reference signal resources included in the tracking reference signal resource set are time division multiplexed, the resource unit mapping patterns of the tracking reference signal resources included in the tracking reference signal resource set in the frequency domain are the same, and/or the tracking reference signal resources between different tracking reference signal resource sets are frequency division multiplexed.

Optionally, the specific examples in this embodiment may refer to the examples described in the above embodiments and optional implementation manners, and this embodiment is not described herein again.

In order that the embodiments of the invention may be better understood, the invention will now be further explained with reference to the preferred embodiments.

Preferred embodiment 1

The preferred embodiment provides specific implementation modes of reference signal configuration and CSI feedback. The base station configures a series of reference signal resources configured into one or more sets of reference signal resources. And the terminal performs measurement and CSI reporting according to the reference signal resource configuration information and the reference signal resource set configuration information. The reference signal resource set configuration parameter includes a parameter indicating whether or not resources in the reference signal resource set are duplicated. When the repeat indication parameter is "ON", the terminal assumes that the precoding of the transmitting end is repeated ON the resources; when the repetition indication parameter is "OFF", the terminal cannot assume that the transmitting-end precoding is the same on these resources. Under the configuration framework, the terminal can measure the sending precoding matrix and the receiving precoding matrix, and can feed back the reference signal resource according to the corresponding configuration condition.

Specifically, if the base station wants to perform measurement ON the combination of the transmit precoding and the receive precoding in the one-time CSI measurement reporting setting, a plurality of reference signal resource sets may be configured, and the repetition indication parameter of each reference signal resource set is ON, as shown in fig. 6. In the configuration of fig. 6, since the repetition indication parameter is repeated ON multiple resources of each reference signal resource set, i.e. the repetition indication parameter is "ON", the terminal assumes that the transmit precoding is kept unchanged ON these resources, and therefore the terminal can make a measurement of the receive precoding. Furthermore, the terminal cannot assume the same transmit precoding between different sets of reference signal resources, and thus polling and measurement of transmit precoding can be performed between different sets of reference signal resources. At this time, when the terminal reports the reference signal resource, it is only necessary to report the reference signal resource set indication (CRSI) without reporting a complete reference signal resource indication (CRI), so as to reduce overhead of CRI reporting.

If the base station wants to measure only the sending precoding in the one-time CSI measurement reporting setting, a reference signal resource set may be configured, and the repetition indication of the reference signal resource is OFF, as shown in fig. 7. In the configuration of fig. 7, since the repetition indication parameter is "OFF" and the terminal cannot assume that the transmission precoding is maintained on a plurality of resources of the reference signal resource set, the base station may poll the transmission precoding on the reference signal resources in the set, and the terminal may perform measurement of the transmission precoding. At this time, when the terminal reports the reference signal resource, it needs to report a complete reference signal resource indication (CRI). Another preferred mode is to encode and report the index of the reference signal resource in the reference signal resource set to the reference signal resource in the reference signal resource set. For example, if the reference signal resource set includes M reference signal resources, then index from 0 to M-1 is coded and reported for the M reference signal resources according to the configuration sequence in the reference signal resource set, or index from 0 to M-1 is coded and reported according to the sequence of the ID of the M reference signal resources, where M is an integer greater than or equal to 1.

If the base station wants to measure only the received precoding in the one-time CSI measurement reporting setting, a reference signal resource set may be configured, and the repetition indication of the reference signal resource is ON, as shown in fig. 8. In the configuration of fig. 8, since the repetition indication parameter is repeated, i.e. the repetition indication parameter is "ON", ON a plurality of resources of each set of reference signal resources ON which the terminal assumes that the transmit precoding is kept unchanged, the terminal may poll the receive precoding ON the reference signal resources within the set to make a measurement of the receive precoding. At this time, the terminal reports the reference signal resource information without reporting.

ON the other hand, optionally, the terminal reports the recommended repetition number information of the reference signal resource set based ON the reference signal resource set with the repetition indication parameter configured as "ON".

ON the other hand, optionally, in the reference signal resource set with the repetition indication parameter configured to be "ON", the interval of the reference signal resources adjacent in the time domain needs to satisfy a certain constraint condition, for example, at least K symbols are spaced, and K > is 0. Further, the restriction condition may be related to a terminal capability.

Preferred embodiment 2

The preferred embodiment provides a specific implementation of the reference signal resource and the reference signal resource set configuration. When configuring the reference signal resource set and the reference signal resource, some configuration optimization restrictions are needed in order to make the measurement of the transmit and receive precoding more accurate.

When the repetition indication parameter of one reference signal set is "ON", training and measurement of receiving precoding are required ON these resources, and therefore, the optimization mode is that the reference signal resources are time division multiplexed in the reference signal set with the repetition indication parameter "ON".

When the repetition indication parameter of one reference signal set is "ON", if the terminal has multiple antenna panels, multiple measurements of reception precoding can be performed simultaneously, and therefore, in the reference signal set with the repetition indication parameter "ON", reference signal resources that cannot be received simultaneously are time division multiplexed.

When the repetition indication parameter of one reference signal is "ON", the terminal performs round training and measurement of receiving precoding, and for accurate measurement, the frequency domain resource unit mapping patterns of the reference signal resources in the reference signal set with the repetition indication parameter of "ON" may be restricted to be the same.

When the repetition indication parameter of one reference signal is "ON", the terminal assumes that the transmission precoding is unchanged, and therefore, in the reference signal set with the repetition indication parameter of "ON", the reference signal resource is QCL with respect to the spatial reception parameter.

Preferred embodiment 3

One specific configuration, measurement and feedback manner is that the repetition indication parameter is default to be "ON" or configurable to be "ON" between the terminal and the base station agreed reference signal resource set, and the repetition indication parameter in the reference set can be configured to be "ON" or "OFF".

If the base station wants to jointly measure the transmit precoding and the receive precoding in the one-time CSI measurement reporting setting, a plurality of reference signal resource sets may be configured, and the repetition indication parameter of each reference signal resource set is OFF, as shown in fig. 9. In the configuration of fig. 9, since the resources of each reference signal resource set are not repeated, that is, the repetition indication parameter is "OFF", and the terminal cannot assume that the transmission precoding is kept unchanged on these resources, the base station may perform transmission precoding polling, and the terminal may perform measurement of the transmission precoding. In addition, between different reference signal resource sets, the repeat indication parameter between the terminal default set is "ON", or the repeat indication parameter between the base station configuration sets is "ON", and the terminal assumes that the same transmission precoding is available ON the reference signal resources at the same position in different sets, so that polling and measurement of reception precoding can be performed between different reference signal resource sets. At this time, when the terminal reports the reference signal resource, the terminal reports the reference signal resource ID information. Another preferred mode is to code and report, for the reference signal resource in each reference signal set, the index of the reference signal resource in the reference signal resource set. For example, if each reference signal resource set includes M reference signal resources, then index from 0 to M-1 is coded and reported for the M reference signal resources according to the configuration sequence in the reference signal resource set, or index from 0 to M-1 is coded and reported according to the sequence of the ID of the M reference signal resources; wherein M is an integer greater than or equal to 1.

In the above manner, a preferable limitation is to limit the number of reference signal resources in each reference signal resource set to be equal.

Preferred embodiment 4

The preferred embodiment provides a specific implementation of the configuration of the tracking reference signal. In the reference signal, there is a function of the reference signal to realize accurate measurement and tracking of time offset and frequency offset, which is called tracking reference signal. The base station configures a series of tracking reference signal resources configured into one or more reference signal resource sets. And the terminal performs measurement according to the configuration information of the tracking reference signal resource and the configuration information of the tracking reference signal resource set.

The base station configures one or more tracking reference signal resource sets, resources in each tracking reference signal resource set are time division multiplexed, a repeat indication parameter of a terminal default tracking reference signal resource set is 'ON', or the base station configures the repeat indication parameter of the tracking reference signal resource set to be 'ON', that is, the terminal confirms that reference signals are repeatedly transmitted in a time domain in each tracking reference signal resource set. Preferably, when the repetition indication parameter is "ON", the resource unit mapping patterns of the resources of the tracking reference signal resource set in the frequency domain are the same. Further, when configuring multiple tracking reference signal resource sets, resources between different tracking reference signal resource sets are frequency division multiplexed. Further, each tracking reference signal resource configuration information includes information such as frequency domain position occupied by the tracking reference signal resource in each RB, number of occupied subcarriers, period, and slot offset.

In another mode, the base station configures one or more tracking reference signal resource sets, resources in each tracking reference signal resource set are frequency division multiplexed, the terminal defaults that a repetition indication parameter of the tracking reference signal resource set is "ON", or the base station configures the repetition indication parameter of the tracking reference signal resource set to be "ON", that is, the terminal confirms that reference signals are repeatedly transmitted in the frequency domain in each tracking reference signal resource set. Preferably, when the repetition indication parameter is "ON", the resource unit mapping patterns of the resources of the tracking reference signal resource set in the time domain are the same. Further, when configuring multiple sets of tracking reference signal resources, resources between different sets of tracking reference signal resources are time-division multiplexed. Further, each tracking reference signal resource configuration information includes information such as frequency domain position occupied by the tracking reference signal resource in each RB, number of occupied subcarriers, period, and slot offset.

Preferred embodiment 5

And the terminal performs measurement of the reference signal and/or reporting of the CSI according to the reference signal resource configuration information, the reference signal resource set configuration information and the repeated indication parameter configuration information.

The base station configures N >1 reference signal resource sets, and when the repeated indication parameter of each reference signal resource set is 'ON', the terminal reports the indication information of the reference signal resource sets according to channel measurement.

The base station configures 1 reference signal resource set, when the repeated indication parameter of the reference signal resource set is OFF, the terminal reports the reference signal resource indication information according to the channel measurement.

And aiming at the reference signal resources in the reference signal set, encoding and reporting the index of the reference signal resources in the reference signal resource set.

If the reference signal resource set contains M reference signal resources, encoding index from 0 to M-1 according to the configuration sequence in the reference signal resource set aiming at the M reference signal resources, and reporting; wherein M is an integer greater than or equal to 1.

If the reference signal resource set contains M reference signal resources, coding index from 0 to M-1 according to the sequence of the ID of the M reference signal resources aiming at the M reference signal resources, and reporting; wherein M is an integer greater than or equal to 1.

When the repetition indication parameter for a set of reference signal resources is "ON", the resources within the set are time division multiplexed.

When the repetition indication parameter of the set of reference signal resources is "ON," the resources within the set are QCL with respect to the spatial reception parameter.

When the repetition indication parameter of the reference signal resource set is "ON", the interval of the reference signal resources adjacent in the time domain in the set in the time domain needs to satisfy a certain constraint condition, for example, at least K symbols are spaced, and K > is 0.

Further, the restriction condition may be related to a terminal capability.

When the repetition indication parameter of the set of reference signal resources is "ON", the resource unit mapping patterns of the resources within the set in the frequency domain are the same.

The base station configures N >1 reference signal resource sets, and the terminal defaults the repeated indication parameter between the reference signal resource sets to be 'ON' according to convention or determines the repeated indication parameter between the reference signal resource sets to be 'ON' or 'OFF' according to the base station configuration.
