The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step 101, a terminal device obtains a TCI status pool configured by a network device, where the TCI status pool is configured based on each carrier unit, or the TCI status pool is configured based on each carrier unit list.

In practical application, the terminal device may obtain a TCI status pool configured by the network device through RRC signaling.

And 102, the terminal device receives a first indication sent by the network device, wherein the first indication comprises information of a target TCI state.

In this step, the terminal device may receive the MAC CE sent by the network device, where the MAC CE includes the information of the target TCI status. The information of the target TCI refers to information of a TCI state after a certain TCI state is updated in a TCI state pool. For example, the information of the target TCI state may be only information of a TCI after the TCI state pool is updated, and may also indicate that a certain TCI state in the TCI state pool is updated to another TCI state, for example, TCI state1 in the TCI state pool is updated to TCI state 5.

And 103, the terminal equipment determines signal receiving reference information according to the information of the target TCI state.

(1) In this step, if the TCI status pool is configured based on each carrier unit list, when it is determined that the reference signal of the first QCL type corresponding to the target TCI status does not exist in the carrier unit configured by the network device according to the information of the target TCI status, the terminal device determines the reference signal of the first QCL type on the carrier unit according to the information of the target TCI status.

Wherein the reference signal of the first QCL type on the carrier unit according to the information of the target TCI state includes: and the terminal equipment determines a target reference signal of a target carrier in which the target TCI state is located according to the information of the target TCI state, and then uses the target reference signal as the reference signal of the first QCL type. Wherein the first QCL type reference signals include one or more of quasi co-located type A (QCL-TypeA) reference signals, quasi co-located type B (QCL-TypeB) reference signals, quasi co-located type C (QCL-TypeC) reference signals, and quasi co-located type D (QCL-TypeD) reference signals. In this way, when the TCI status pool is configured on a per carrier unit basis, the terminal device may be enabled to accurately determine the reference signals of the first QCL type. Then, the terminal device may receive the downlink channel according to the receiving beam of the QCL-Type reference signal included in the target TCI state, estimate the large-scale fading of the downlink channel according to the QCL-Type a reference signal, and demodulate data according to the estimation result.

Wherein the target reference signal is predefined or configured by the network device. For example, the target reference signal may be a reference signal with a smallest index or a largest index in a target carrier.

(2) In this step, if the TCI status pool is configured on a per carrier unit basis, the terminal device determines that the target TCI status does not exist in the TCI status pool according to the information of the target TCI status, and the terminal device obtains the target TCI status according to the information of the target TCI status.

The terminal device, according to the information of the target TCI status, acquiring the target TCI status, including: the terminal device determines a target TCI state pool associated with a carrier unit where the target TCI state is located, and the terminal device takes a first TCI state in the target TCI state pool as the target TCI state. In this way, when the TCI status pool is configured on a per carrier unit basis, the terminal device can accurately determine the target TCI status. Then, the terminal device may receive the downlink channel according to the receiving beam of the QCL-TypeD reference signal included in the target TCI-state.

Wherein the first TCI state is predefined or configured by the network device. For example, the first TCI state may be the index minimum or maximum TCI state in the target TCI state pool.

And step 104, the terminal equipment receives the downlink signal according to the signal receiving reference information.

Specifically, the terminal device receives the downlink channel according to a receiving beam of the QCL-TypeD reference signal included in the target TCI-state. And if the TCI state pool is configured on the basis of each carrier unit list, the terminal estimates the large-scale fading of the downlink channel according to the determined QCL-Type A reference signal and demodulates the data according to the estimation result.

In this embodiment of the present application, when a TCI status pool configured by a network device is configured on a per carrier unit basis, or when the TCI status pool is configured on a per carrier unit list basis, a terminal device determines signal reception reference information according to information of a target TCI status sent by the network device, and receives a downlink signal. Therefore, by using the scheme of the embodiment of the application, the downlink signal can be received based on the beam where the reference signal included in the target TCI state is located or the beam where the QCL-type reference signal on the carrier unit is located, thereby ensuring the reception of the downlink signal.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided in an embodiment of the present application, and as shown in fig. 2, includes the following steps:

step 201, the network device configures a TCI status pool, where the TCI status pool is configured on a per carrier unit basis, or the TCI status pool is configured on a per carrier unit list basis.

In practical applications, the network device configures the TCI status pool through RRC signaling.

Step 202, the network device sends a first indication to a terminal device, where the first indication includes information of a target TCI status.

In this step, the network device may transmit the MAC CE including the information of the target TCI state in the MAC CE to the terminal device.

The following describes a specific implementation process of an embodiment of the present application by way of example. The network device is described by taking a base station as an example.

In one embodiment, assume that the base station configures two CC lists for the terminal device through RRC: CC list1{ CC 1; CC2 }; CC list2{ CC 3; CC 4; CC5 }. Meanwhile, the base station configures a reference signal set on the CC1 as { CSI-RS 1; CSI-RS 2; CSI-RS 3; CSI-RS 4; CSI-RS 5; CSI-RS 6; CSI-RS7, and the reference signal set on CC2 is { CSI-RS 1; CSI-RS 2; CSI-RS3 }. Wherein, the reference signals are arranged from small to large according to the indexes.

The base station configures TCI state pool 1{ C1_ TCI-state 1; c1_ TCI-state 2; c1_ TCI-state3}, and TCI state pool1 is associated with CC list 1.

The base station configures TCI state pool 2{ C2_ TCI-state 1; c2_ TCI-state 2; c2_ TCI-state3}, and TCI state pool2 is associated with CC list 2.

In the nth time slot, the base station indicates through the MAC CE that the beam of the downlink channel is updated as indicated by C2_ TCI-state3 as indicated by the previous C1_ TCI-state1 indication.

Wherein the structure of C1_ TCI-state1 is:

{TCI-state ID#1

CSI-RS1；QCL type-A；

CSI-RS2；QCL type-D；

CC index:1

}

the structure of C2_ TCI-state3 is:

{TCI-state ID#3

CSI-RS6；QCL type-A；

CSI-RS3；QCL type-D；

CC index:2

}

in an embodiment of the present application, when there is no reference signal of QCL-type a indicated by the target TCI status on the current CC, the system predefined criterion is that the indicated reference signal of QCL-type a is determined by the reference signal with the smallest index on the current CC.

The terminal equipment receives the MAC-CE indication of the base station, determines that the QCL type-D reference signal contained in the C1_ TCI-state3 is CSI-RS3, and receives downlink data by using a receiving beam of the CSI-RS3 on the CC 2. Meanwhile, the terminal equipment determines that a reference signal of QCL type-A in C1_ TCI-state3 is CSI-RS6, and the terminal equipment uses CSI-RS6 as the reference signal of QCL-type A on CC 1; estimates the large scale fading experienced by the data channel on CC1 and demodulates the data according to the estimation.

On the CC2, because the CSI-RS6 is not configured, the terminal device uses the reference signal with the lowest index on the CC2, i.e., CSI-RS1, as the reference signal of QCL-Type a according to the system predefined criteria to estimate the large scale fading experienced by the data channel, and demodulates the data according to the estimation result.

In one embodiment, assume that the base station configures 2 CCs for the terminal device through RRC: CC1, CC 2. Meanwhile, the base station configures a TCI state pool1 for the terminal device through RRC: { TCI-state 1; TCI-state 2; TCI-state3}, and TCI state pool1 is associated with CC 1. The base station configures TCI state pool2 for the terminal equipment through RRC: { TCI-state 1; TCI-state 2; TCI-state 3; TCI-state 4; TCI-state5}, and TCI state pool2 is associated with CC 2. Meanwhile, the base station configures a reference signal set on the CC1 as { CSI-RS 1; CSI-RS 2; CSI-RS 3; CSI-RS 4; CSI-RS 5; CSI-RS 6; CSI-RS7, the reference signal set on CC2 is { CSI-RS 1; CSI-RS 2; CSI-RS3 }. Wherein, the TCI states are arranged from small to large according to the index.

In the nth time slot, the beam of the downlink channel indicated by the base station through MAC CE signaling is indicated by TCI-state1 to be updated to be indicated by TCI-state 5.

Wherein, the structure of TCI-state1 is:

{TCI-state ID：1

CSI-RS1；QCL type-D；

CC index:1

}

the structure of TCI-state5 is:

{TCI-state ID：5

CSI-RS3；QCL type-D；

CC index:2

}

and when the target TCI state does not exist on the current CC according to the predefined criterion of the system, determining the target TCI state according to the TCI state with the lowest index on the current CC.

And the terminal equipment receives the MAC CE indication of the base station and determines that the target TCI-state is TCI-state 5. The terminal device receives the downlink channel on the CC2 with the reception beam of the reference signal CSI-RS3 contained in the TCI-state 5. The system is not configured with TCI-state5 on the CC1, the terminal device determines the TCI-state with the lowest index on the current CC as TCI-state1 according to the predefined criteria of the system, and takes TCI-state1 as the target TCI state.
