Abstract

The embodiment of the invention provides CSI reporting methods, a terminal and network equipment, relates to the technical field of communication, and aims to solve the problem that in the prior art, UE reports wrong CSI due to the fact that the UE cannot accurately know the number of BWPs currently activated by the network equipment.

Description

CSI reporting method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network device for reporting types of Channel State Information (CSI).

Background

In the 5G NR system, a network device may configure a Bandwidth Part (BWP) set available for each cell for a UE through Radio Resource Control (RRC) signaling, and dynamically switch a BWP to be started through L1 signaling, that is, when the network device activates BWPs, the network device may deactivate a currently activated BWP through L1 signaling, where activation/deactivation of the BWP is activation/deactivation of a Physical Downlink Control Channel (PDCCH) in .

In the prior art, when reporting CSI of activated and/or deactivated BWPs, the UE reports the number of currently activated and/or deactivated BWPs based on the network device, however, since the L1 signaling for activating and deactivating BWPs is not stable, the UE is prone to lose the signaling, so that the UE cannot accurately know the number of currently activated BWPs of the network device, and further the UE reports wrong CSI.

For example, the network side activates 3 BWPs of the UE, the network side wants to further deactivate steps of BWPs, and if the PDCCH deactivation signaling (i.e., L1 signaling) is lost, the UE does not deactivate the BWPs, and at this time, the network side will understand that the UE currently activates only 2 BWPs, that is, the UE will report CSI corresponding to 2 activated BWPs, however, in an actual scenario, the UE side will still report CSI corresponding to 3 activated BWPs.

Fig. 2 shows a flow diagram of CSI reporting methods provided by the embodiment of the present invention, and as shown in fig. 2, the CSI reporting method may include:

step 201: and the terminal acquires the indication information.

In an embodiment of the present invention, the indication information is used to indicate that the terminal reports csi corresponding to a unit frequency resource , where the unit frequency resource includes all or part of unit frequency resources activated by the terminal and/or all or part of unit frequency resources deactivated by the terminal, where the unit frequency resources include BWP or CC, and the CC is a CC aggregated by CA.

The th unit frequency resource may be related to a unit frequency resource activated by the network device, or may be unrelated to a unit frequency resource activated by the network device, which is not limited in the present invention.

Example 1, the network device activates three BWPs, BWP1, BWP2 and BWP3, and the network device wants to deactivate BWP3 in step , if the L1 signaling is lost, the terminal is not deactivated by BWP3, that is, the BWP activated by the terminal is still three BWPs, BWP1, BWP2 and BWP 3.

Example 2: before activating three BWPs, namely, BWP1, BWP2 and BWP3, the network device may send indication information to the terminal in advance to indicate the terminal to report CSI of the three BWPs, namely, BWP1, BWP2 and BWP3, and if the terminal only activates BWP1 and BWP2 and deactivates BWP3 at this time, the terminal may report CSI of activating BWP1 and BWP2 and deactivating BWP 3.

Optionally, in the embodiment of the present invention, the indication information is specifically used to indicate the th unit frequency resource number N and/or the th unit frequency resource, where N is a positive integer greater than or equal to 1.

Optionally, in this embodiment of the present invention, the indication information includes at least items including an identifier of a th unit frequency resource (e.g., an index of BWP or an index of CC), a number N of a th unit frequency resource, and a group identifier of a unit frequency resource group, where N is a positive integer greater than or equal to 1, and the unit frequency resource group includes a th unit frequency resource.

It should be noted that the above-mentioned unit-frequency resource group (i.e. CC group or BWP group) may be configured by the network device to the terminal (e.g. configured by the network device using RRC signaling) or predefined (e.g. protocol specification).

And step 202, the terminal reports the CSI corresponding to the th unit frequency resource to the network equipment according to the indication information.

Optionally, in the embodiment of the present invention, the step 201 may be implemented in at least three ways.

implementation:

illustratively, the step 201 includes the following steps:

step 201 a: and the terminal receives the indication information sent to the terminal by the network equipment.

Correspondingly, the opposite terminal network equipment sends the indication information to the terminal. At this time, the indication information is specifically used for indicating the terminal to report CSI to the network device according to the indication information.

The network device in the embodiment of the present invention may be a network device in the communication system shown in fig. 1, for example, a base station; the terminal in the embodiment of the present invention may be a terminal in the communication system shown in fig. 1.

The second implementation mode comprises the following steps:

illustratively, as shown in fig. 3, the step 201 specifically includes the following steps:

step 201b 1: the network device transmits the PDCCH to the terminal.

Step 201b 2: and the terminal decodes the PDCCH acquired by the terminal and acquires the indication information carried in the PDCCH.

For example, the network device directly indicates the terminal to report the CSI of BWP1, BWP2, and BWP3 in the PDCCH, and after monitoring the PDCCH, the terminal may decode the PDCCH to obtain the indication information, so as to report the CSI of BWP1, BWP2, and BWP 3.

The third implementation mode comprises the following steps:

in this embodiment of the present invention, the indication information may be carried in an RRC signaling or a Media Access Control entity (MAC CE).

Example 3: when the network device activates 3 BWPs or CCs, the network device only reports CSI of 3 BWPs or CCs through the RRC signaling configuration terminal.

For example, the embodiment of the present invention may separately perform the activation of reporting the CSI and the activation of the BWP or CC. Specifically, when BWP or CC is activated/deactivated by using PDCCH, the reporting of CSI is no longer dependent on the activation/deactivation of BWP or CC. Wherein the activation/deactivation of BWP or CC indicates: whether to monitor PDCCH on the BWP, whether to receive PDSCH on the BWP or CC, and whether to transmit PUSCH on the BWP or CC. At this time, if the CSI needs to be sent, the MAC CE may be used to activate the reporting of the CSI.

Example 4, in a scenario that the network device activates 5 BWPs through the PDCCH, if the CSI of the 5 BWPs is not activated yet, the network device may further send, through the MAC CE, indication information, where the indication information is a BWP CSI activation command indication, and is used to indicate the terminal to activate CSI transmission of all or part of the 5 BWPs, so as to indicate the terminal to activate CSI transmission of all or part of the BWPs in the 5 BWPs within a specified time.

For example, the indication information is used to indicate that transmission of CSI for BWP1, BWP2, and BWP3 is activated, and after receiving the indication information, the terminal activates transmission of CSI for BWP1, BWP2, and BWP3 within a predetermined time according to the indication of the indication information.

The fourth implementation mode comprises the following steps:

exemplarily, as shown in fig. 4, in the embodiment of the present invention, the step 201 specifically includes the following steps:

step 201c1, the network device transmits the PDCCH to the terminal on the BWP according to a second predetermined rule.

Step 201c 2: the terminal decodes the PDCCH acquired by the terminal and acquires indication information.

In an embodiment of the present invention, the indication information is BWP information where the PDCCH of the terminal or the PDCCH is located, where the BWP is BWP activated by the network device or BWP in the CC.

Optionally, in the embodiment of the present invention, the step 202 may be implemented in at least two ways.

implementation:

for example, as shown in fig. 5, in the embodiment of the present invention, in a scenario that the indication information is specifically used for indicating the th unit frequency resource number N, the step 202 specifically includes the following steps:

step 202a, the terminal reports the CSI corresponding to the unit frequency resource to the network equipment according to the indication information and preset rules.

Wherein the predetermined rule includes at least items of unit frequency resource before N of the channel quality rank and the unit frequency resource before N of the unit frequency resource number rank.

For example, the network device configures the terminal to report CSI of only 3 BWPs through an RRC message, so that the terminal does not understand an error for PUCCH format, and further step, where for the specific BWPs activated by the network device, multiple rules may be defined, for example, the best 3 BWPs of a channel command, or the maximum 3 BWP indexes, or special BWPs (for example, first BWP, or default BWP, or primary BWP, etc.).

Further , in this embodiment of the present invention, the predefined rule is configured by the network device to the terminal (e.g., the network device is configured to the terminal by RRC signaling) or predefined (e.g., specified by a protocol).

It should be noted that this implementation manner may be combined with at least of the above four implementation manners of step 201, and this is not limited by the embodiment of the present invention.

The second implementation mode comprises the following steps:

for example, as shown in fig. 4, in the embodiment of the present invention, in combination with the contents in step 201c1 and step 201c2, step 202 specifically includes the following steps:

and step 202c, the terminal reports the CSI corresponding to the th unit frequency resource to the network equipment according to the indication information and the second preset rule.

In this embodiment of the present invention, when the th unit frequency resource is a BWP, the second predetermined rule includes at least that the 0 th unit frequency resource is a 1 th BWP, and the 2 th unit frequency resource is a BWP in the second BWP or BWP group corresponding to the th BWP, or when the th unit frequency resource is a CC, the second predetermined rule includes at least that the th unit frequency resource is a th BWP, and the th unit frequency resource is a CC in the th CC or CC group corresponding to the th BWP.

Further , the second predetermined rule mentioned above in this embodiment of the present invention is configured by the network device to the terminal (e.g., configured by the network device to the terminal by RRC signaling), or predefined (e.g., specified by a protocol).

The third implementation mode comprises the following steps:

illustratively, in examples, when the unit frequency resource includes at least unit frequency resources activated by the terminal, the foregoing step 202 specifically includes the following steps:

and step 202d, the terminal reports the CSI corresponding to all th unit frequency resources to the network equipment according to the indication information.

For example, if the network device sends the indication information to the terminal, the network device indicates the terminal to report the CSI of three BWPs, BWP1, BWP2, and BWP 3. If the terminal receives the indication information, the terminal activates BWP1 and deactivates BWP2 and BWP3, and the terminal reports CSI for activating BWP1 and deactivating BWP2 and BWP 3.

In addition, it should be noted that, when the th unit frequency resource is the unit frequency resource deactivated by the terminal, the terminal does not report the CSI to the network device.

In the CSI reporting method provided in the embodiment of the present invention, the network device sends the indication information to the terminal to indicate the terminal to report the CSI corresponding to the th unit frequency resource to the network device, and since the th unit frequency resource includes all or part of the unit frequency resources activated by the terminal and/or all or part of the unit frequency resources deactivated by the terminal, the terminal is ensured to be capable of reporting the CSI flexibly and accurately, that is, reporting the CSI corresponding to BWP accurately and/or accurately.
