Description

Trigger state configuration method and device, communication system

Technical field

The present invention relates to the field of communications, and in particular, to a trigger state configuration method and apparatus, and a communication system.

Background technique

In a Long Term Evolution (LTE) system, a terminal device can obtain channel state information (CSI) by measuring a reference signal, and report the channel state information to a network side, where the channel state information includes a channel quality indicator (CQI, The channel quality indicator may further include a Precoding Matrix Indicator (PMI) and a Rank Indication (RI) information for some downlink transmission modes.

Currently, channel state information can be reported periodically or aperiodically. Here, for convenience of description, the periodically reported channel state information CSI is referred to as periodic channel state information CSI, and the non-periodically reported channel state information CSI is referred to as aperiodic channel state information CSI.

When the terminal device is required to report the non-period CSI, the following manner may be adopted: when the network device needs to report the non-period channel state information CSI, the downlink control information (DCI, Downlink Control Information) may be sent to the terminal device. The DCI triggers the terminal device to perform aperiodic CSI reporting, and indicates, to the terminal device, a corresponding resource used for reporting the aperiodic CSI; when the terminal device receives the DCI, may report a non-report according to the resource indicated in the DCI. Periodic CSI.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these aspects are set forth in the background section of the present invention.

Summary of the invention

In a fifth generation (5G) mobile communication system, such as a new radio (NR, New Radio) system, the network side may perform a measurement configuration for the terminal device, and in the measurement setting, at least one resource configuration (Resource) Setting, at least one CSI reporting configuration and a link configuration, wherein the at least one resource configuration is associated with at least one reporting configuration, and one reporting configuration configuration may link one or at least two resource configurations, and one resource configuration may also be Link one or at least two escalation configurations.

Currently, the network side may be configured in advance for a plurality of aperiodic CSI reporting trigger states, and each of the triggering states may be configured to be associated with one or at least two aperiodic CSI reporting configurations, where a non-periodic CSI reporting is specified in the protocol. The DCI triggers, and the network side indicates a certain triggering state by using the DCI. According to the indication of the DCI, the terminal device can determine the triggering state reported by the aperiodic CSI, and further determine the reporting configuration associated with the triggering state.

The inventor has found that the aperiodic CSI reporting configuration associated with the same triggering state will be triggered at the same time. Therefore, if multiple resource configurations are associated with the same aperiodic CSI reporting configuration, they can only be triggered at the same time. If the configuration of the multiple resource configurations is the same, but the scenario with different triggering times is set, the network side can configure different acyclic CSI reporting configurations in the measurement configuration. The configurations of the reporting configurations are the same (that is, the reported content is the same), but The configuration of the different triggering states is respectively configured to solve the problem of triggering reporting of the aperiodic CSI in the same scenario where the multiple resource configurations need to be reported, but in the scenario, the different aperiodic CSI reports are configured. The configuration content is the same except for the identification identifier of the configuration, thus causing unnecessary signaling overhead and lacking flexibility in configuration scheduling.

The beneficial information of the embodiment of the present invention is that, by configuring the identifier information corresponding to the different triggering states, the identifier information is used to identify an aperiodic CSI reporting configuration corresponding to a triggering state and at least one resource configuration linked thereto, and the solution is solved. If the configuration of multiple resources is the same, the triggering of the non-periodic CSI in the scenario with different triggering times is reported, and the signaling overhead is saved, and the flexibility of configuration scheduling is improved.

Example 1

The embodiment of the present invention provides a method for configuring a trigger state, and FIG. 2 is a flowchart of a method for configuring a trigger state in the embodiment, which is applied to a network device side. As shown in FIG. 2, the method includes:

Step 201: The network device sends configuration information of the trigger status of the aperiodic CSI reporting to the terminal device, where the configuration information includes at least one identifier information corresponding to each triggering state, where the identifier information is used to identify a triggering state. An aperiodic CSI reports configuration and resource configuration linked to it.

In this embodiment, the network device may configure configuration information of N (N is greater than or equal to 1) triggering states reported by the aperiodic CSI, where the configuration information includes each trigger state of the N trigger states. Corresponding M (M is greater than or equal to 1) identification information, each identifier information is used to identify an aperiodic CSI reporting configuration corresponding to a triggering state and a resource configuration linked thereto, and send the configuration information to the terminal device, When the terminal device receives the trigger signaling, according to the triggering state indicated by the triggering signaling and the configuration information, determining an aperiodic CSI reporting configuration corresponding to the indicated triggering state and the resource configuration linked thereto, according to the reporting configuration And the resource configuration is performed on the aperiodic CSI, and the number of the triggering states N may be configured as needed, and may be one or at least two. This embodiment is not limited thereto.

In this embodiment, the configuration information may be expressed as: (wherein the numbers 1 to M ₁ (or M ₂ , . . . , M _N ) are only distinguishing different identification information, and do not represent the identification information itself, M ₁ (or M ₂ ,...,M _N ) is greater than or equal to 1)

Trigger state 1: identification information 1, identification information 2, ..., identification information M ₁ ;

Trigger state 2: identification information 1, identification information 2, . . . , identification information M ₂ ;

....

Trigger state N: identification information 1, identification information 2, ..., identification information M _N ;

In this embodiment, a triggering state corresponds to a triggering time reported by an aperiodic CSI, and a reporting configuration and resource configuration corresponding to the aperiodic CSI reporting at the triggering time, and the triggering time of the aperiodic CSI reporting corresponding to the different triggering states is different. The triggering time corresponding to the same triggering state is the same, wherein if M ₁ (or M ₂ , . . . , M _N ) is equal to 1, it means that the triggering state (triggering time) corresponds to only one reporting configuration and is linked thereto. The resource configuration, if M ₁ (or M ₂ , . . . , M _N ) is greater than 1, indicates that the trigger state (trigger time) corresponds to at least two pairs of aperiodic CSI reporting configurations and resource configurations linked thereto, at least In the case of two pairs of acyclic CSI reporting configurations and the resource configurations linked to them, the reporting configurations can be the same or different. When the reporting configurations are the same, the resource configurations are different. When the reporting configurations are different, the resource configurations can be the same or different. Relevant parameters reported, such as periodicity of reporting (eg, periodic, semi-persistent, aperiodic), reported content, bandwidth, and codebook used, etc. The resource configuration includes the related parameters of the resources used by the CSI, such as the periodicity of the resources (eg, periodic, semi-persistent, aperiodic), time-frequency location, density, bandwidth, etc., wherein the reporting configuration and resource configuration may be pre-configured by the network device. Configure in the measurement configuration.

Therefore, in this embodiment, the method may further include:

Step 200: The network device sends a measurement setting to the terminal device, where the measurement configuration includes a measurement link configuration, where the measurement link configuration includes a measurement link identifier and an aperiodic CSI reporting configuration corresponding to the measurement link identifier, and A resource configuration that is linked to it.

In this embodiment, in step 200, the network device may perform measurement configuration on the terminal device, where the measurement configuration includes at least one resource configuration and at least one reporting configuration, and, in order to represent the at least one resource configuration and at least one report a one-to-one correspondence of the configuration, the measurement configuration further includes at least one measurement link configuration (CSI-MeasIdToAddMod), wherein the measurement link identifier indicates that the report configuration and the resource configuration have a one-to-one correspondence, that is, one report of the link Configuration and a resource configuration, also known as a measurement link (Link).

FIG. 3 is a schematic diagram of the measurement configuration in the embodiment. As shown in FIG. 3, the measurement configuration includes X (X is greater than or equal to 1) resource configuration, and Y (Y is greater than or equal to 1) reporting configuration, wherein there is a pair. The reporting configuration and resource configuration of a corresponding relationship (linked) are reporting configuration 2 and resource configuration 1, reporting configuration Y and resource configuration 1, reporting configuration 1 and resource configuration 2....., reporting configuration Y and resources. Configure X for a total of L measurement links, namely Link1, Link2, ..., LinkL, where the

index

1, 2, ..., L can be used to represent the measurement link identifier.

The following explains how to configure this identification information.

In one embodiment, the measurement link identifier is used as the identification information.

In this embodiment, since the measurement link identifier configured in step 200 can uniquely identify a report configuration and a resource configuration linked thereto, the measurement link identifier in step 200 can be used as the identification information to identify and trigger. A report configuration corresponding to the status and the resource configuration linked thereto. Therefore, when the report content of the at least two resource configurations is the same (for example, the same report configuration is linked), but the report needs to be reported at different trigger times, the at least two The measurement links corresponding to the resource configurations (represented by the measurement link identifiers) are configured to different trigger states, so that at least two resource configurations of the same report configuration can be reported to report the same content at different trigger times, wherein the measurement link identifier Can be an index.

In this embodiment, when the reporting content of the at least two resource configurations is the same (for example, the same reporting configuration is linked), and the triggering time is also the same, the measurement link corresponding to the at least two resource configurations may be respectively used (using the measurement link) The identifier indicates that the configuration is performed in the same triggering state, and the terminal device performs the joint reporting based on the resources configured by the at least two resource configurations. For details, refer to the description in Embodiment 2. 4 is a schematic diagram of the identification information. As shown in FIG. 4, the periodic resource configuration k and the

aperiodic resource configuration

1, 2 need to report the same content, that is, the link reporting configuration 1, the periodic resource configuration k, and the aperiodic resource are required. Configuration 3 needs to report different content, that is, non-periodic resource configuration 3 requires link reporting configuration 2. In the measurement configuration, the measurement link identifiers are Link1, Link2, Link3, and Link4, respectively, so Link1, Link2, and Link3 can be used. Link4 is used as the identification information. The triggering time (trigger state) of the periodic resource configuration k and the

aperiodic resource configuration

1, 2 is different for the reporting configuration 1, respectively, the triggering state 1 and the triggering state 2, respectively, for the reporting configuration 2, The triggering time (trigger state) of the periodic resource configuration k is the triggering state 1. Therefore, Link1 and Link4 are configured to the triggering state 1, and Link2 and Link3 are configured to the triggering state 2, that is, the configuration information is:

Trigger state 1: Link1, Link4;

Trigger state 2: Link2, Link3;

In this implementation manner, the measurement link identifier may be directly used as the identification information to uniquely identify an aperiodic CSI reporting configuration corresponding to a trigger state and a resource configuration linked thereto, and the resource configuration link identified by the different measurement link identifier If the triggering time is different, the measurement link identifiers corresponding to different resource configurations will be configured to different trigger states. Therefore, the problem that the multi-period CSI triggers reporting in the scenario where the multiple resource configurations need to be reported is the same, but the signaling time is saved, and the flexibility of configuration scheduling is improved.

In an embodiment, the measurement link configuration further includes the identification information, that is, when performing the measurement configuration, for a measurement link configuration, except that the measurement link identifier and an aperiodic CSI reporting configuration corresponding to the measurement link identifier are configured and A resource configuration linked to it, and the configuration of the identification information is also added.

In this embodiment, in the measurement link configuration (CSI-MeasIdToAddMod), the identification information is configured for a corresponding aperiodic reporting configuration, wherein the triggering state corresponding to at least two resource configurations linked to an aperiodic CSI reporting configuration When the identification information configured in the measurement link configuration of the at least two resource configurations is different, and the trigger state corresponding to the at least two resource configurations linked to the aperiodic CSI reporting configuration is the same, corresponding to the The identification information configured in the measurement link configuration of each of the at least two resource configurations is the same.

In this embodiment, the identifier information is represented as a report configuration identifier-sub-identity, for example, when the trigger states corresponding to the at least two resource configurations linked to one aperiodic CSI reporting configuration are different, corresponding to the at least two resource configurations. The respective sub-identities are different; when the triggering states corresponding to the at least two resource configurations that are linked to the one-period CSI reporting configuration are the same, the sub-identities corresponding to the at least two resource configurations are the same; however, the present invention is not limited thereto. The reporting configuration identifier and the sub-identity may be an index.

FIG. 5 is a schematic diagram of the identification information. As shown in FIG. 5, the periodic resource configuration k and the

aperiodic resource configuration

1, 2 need to report the same content, that is, link reporting configuration 1, periodic resource configuration k, and aperiodic resources are required. Configuration 3: The content of the non-periodic resource configuration 4 needs to be reported differently, that is, the non-periodic resource configuration 3, and the non-periodic resource configuration 4 requires the link reporting configuration 2. In the measurement configuration, the included measurement link identifiers are Link1, Link2, and Link3, respectively. Link4, Link5, where Link1, Link2, and Link3 correspond to report configuration 1, Link4, and Link5 correspond to report configuration 2, for one report configuration 1, for one report configuration of its corresponding measurement link identifiers Link1, Link2, and Link3. And the configuration information is configured in a resource configuration, where the triggering time (state) corresponding to the periodic resource configuration k and the aperiodic resource configuration 1 is different (the triggering

states

1 and 2 respectively, and the corresponding identification information is different), the aperiodic The triggering times (states) corresponding to the

resource configurations

1, 2 are the same (the corresponding identification information is the same), and therefore, the identification information is divided into 1-0, 1 -1, 1-1, for one report configuration 2, for its corresponding measurement link identifier Link4, a report configuration and a resource configuration of each of Link5 are configured to configure the identifier information, wherein the aperiodic resource configuration 3 and the aperiodic The triggering time (state) corresponding to the resource configuration 4 is different (the triggering

states

1 and 2 are respectively different, and the corresponding identification information is different). Therefore, the identification information is divided into 2-0 and 2-1, that is, the configuration information is:

Trigger state 1:1-0, 2-0;

Trigger state 2: 1-1, 2-1;

In this embodiment, when the number of pieces of identification information corresponding to one triggering state is at least two, the aperiodic CSI reporting configuration identified by the at least two pieces of identification information is different, for example, an identifier corresponding to one triggering state 1. When the number of information is at least two 1-0, 2-0, the acyclic CSI reporting configuration identified by the at least two pieces of identification information is different, respectively 1, 2, and the number of identification information corresponding to one triggering state 2 is At least two 1-1, 2-1, the aperiodic CSI reporting configuration identified by the at least two pieces of identification information is different, respectively, is 1, 2 for at least two pieces of identification information, if their corresponding trigger states are the same, then The reporting configuration identified by the at least two pieces of identification information is different.

In this implementation manner, the identifier information may be added to the measurement link configuration to uniquely identify an aperiodic CSI reporting configuration corresponding to a trigger state and a resource configuration linked thereto, and different resource configuration links are reported in the same configuration, but the triggering time is At the same time, the identification information corresponding to different resource configurations will be configured to different trigger states. Therefore, the problem of trigger reporting of aperiodic CSI in a scenario in which the multiple resource configurations need to be reported is the same, but the triggering time is different, and the signaling overhead is saved, and the flexibility of configuration scheduling is improved.

In this embodiment, the configuration information of the triggering state in step 201, and/or the measurement configuration in step 200 may be carried by radio resource control signaling or media access control signaling, which is not used in this embodiment. As a limitation.

In this embodiment, when the network device requires the terminal device to report the CSI in a non-period, the method further includes: sending the triggering signaling to the terminal device, where the triggering signaling is used to indicate the triggering state. For example, the triggering signaling may be a DCI, and may be based on the DCI. The predetermined number of bits are used to indicate the trigger state, and the predetermined number is related to the trigger state. For example, when the trigger state is 4, the trigger state may be indicated by 2 bits, where 00 indicates the trigger state 1, 01 indicates the trigger state 2, 10 The triggering state 3, 11 indicates the triggering state 4, which is merely illustrative here, and the embodiment is not limited thereto.

According to the foregoing embodiment, the identifier information is used to identify an aperiodic CSI reporting configuration corresponding to a triggering state and at least one resource configuration associated with the triggering state, and the multiple resources are solved. The problem of reporting the non-periodic CSI triggering in the scenario with the same triggering time is the same, and the signaling overhead is saved and the flexibility of configuration scheduling is improved.
