Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present invention. As shown in fig. 1, the UE includes a User terminal 11 and a base station 12, where the User terminal 11 may be a terminal Equipment (UE), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID, Mobile Internet Device), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention. The base station 12 may be a base station of 5G and later releases (e.g., a gNB, a 5G NR NB), or a base station in other communication systems, or referred to as a node B, and it should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the base station 12 is not limited.
It should be noted that the specific functions of the user terminal 11 and the base station 12 are described in detail through a plurality of embodiments below.
Fig. 2 is a flowchart illustrating a reference signal resource allocation method according to an embodiment of the present invention. The method is applied to the network side equipment, and can be as follows.
Step 210 sends a high-level signaling, where the high-level signaling includes: first configuration information of a first CSI-RS resource set associated with a beam report, the first configuration information including a CSI-RS resource Identification (ID); the second CSI-RS resource set and the third CSI-RS resource set are configured with different CSI-RS resources, the second CSI-RS resource set is a first CSI-RS resource set with a repeat parameter (repetition) value of on (on), and the third CSI-RS resource set is a first CSI-RS resource set with a repeat parameter (repetition) value of off (off).
In a downlink beam training process of an analog beam forming technology and a digital-analog hybrid beam forming technology, network side equipment sends first configuration information of a first CSI-RS resource set associated with a beam measurement to terminal equipment through high-level signaling, so that the terminal equipment can perform beam measurement based on CSI-RS resource indicated by CSI-RS resource ID in the first CSI-RS resource set, and feeds back the beam measurement result including the beam measurement result to the network side equipment.
Since the terminal device uses the physical layer Reference Signal Received Power (L1-RSRP, L1 Reference Signal Received Power) as the measurement result to characterize the beam quality during beam measurement, when the network side device configures the sub-parameter reporting quantity in the higher-layer parameter CSI-reporting as a value related to L1-RSRP (e.g., "CSI-RSRP" or "SSB-Index-RSRP"), the CSI-reporting is used to indicate beam reporting.
The network side equipment also determines first configuration information of a first CSI-RS resource set associated with the beam report through a parameter CSI-ResourceConfig, and then sends the first configuration information to the terminal equipment through a high-level signaling, wherein the first configuration information comprises a repetition, and the value of the repetition is on or off.
For a first CSI-RS resource set (hereinafter, referred to as a "second CSI-RS resource set") with a repetition value of on, the terminal device may determine that Non-Zero Power channel state information reference signal resources (NZP-CSI-RS resources, Non-Zero Power NZP-CSI-RS resources) indicated by CSI-RS resource IDs in the second CSI-RS resource set use the same downlink beam and each symbol has the same port number;
namely, the network side device sends the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set to the terminal device in the same beam direction, and the terminal device performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set by autonomously switching the receiving direction of the terminal device and feeds back a beam report including the beam measurement result to the network side device.
For a first CSI-RS resource set (hereinafter referred to as a "third CSI-RS resource set") whose repetition value is off, the terminal device cannot determine whether the NZP-CSI-RS resources indicated by the CSI-RS resource IDs in the third CSI-RS resource set use the same downlink beam, and whether each symbol has the same port number;
that is, the network side device sends the CSI-RS resources indicated by the CSI-RS resource IDs in the third CSI-RS resource set to the terminal device in different beam directions in a polling manner, and the terminal device performs beam measurement on the CSI-RS resources indicated by the CSI-RS resource IDs in the third CSI-RS resource set by autonomously switching the receiving direction of the terminal device itself, or the terminal device in the same receiving direction, and feeds back a beam report including a beam measurement result to the network side device.
Since the terminal device needs to adopt different beam measurement modes for the second CSI-RS resource set and the third CSI-RS resource set, in order to ensure that the terminal device accurately performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set or the CSI-RS resource indicated by the CSI-RS resource ID in the third CSI-RS resource set, the second CSI-RS resource set and the third CSI-RS resource set are configured with different CSI-RS resource IDs.
If the second CSI-RS resource set and the third CSI-RS resource set are configured with the same CSI-RS resource ID, the terminal device cannot accurately perform beam measurement.
For example, the second CSI-RS resource set and the third CSI-RS resource set are both configured with a CSI-RS resource ID of 1.
When the terminal device performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID ═ 1 in the second CSI-RS resource set, the terminal device needs to autonomously switch its receiving direction, and perform beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID ═ 1 in the second CSI-RS resource set in different receiving directions;
when the terminal device performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID of 1 in the third CSI-RS resource set, the terminal device may need to perform beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID of 1 in the third CSI-RS resource set in the fixed receiving direction.
When the network side device sends the CSI-RS resource indicated by CSI-RS resource ID ═ 1 to the terminal device, the terminal device cannot determine how to measure the CSI-RS resource indicated by CSI-RS resource ID ═ 1, or cannot measure the CSI-RS resource indicated by CSI-RS resource ID ═ 1 in a correct measurement manner.
Therefore, the second and third CSI-RS resource sets cannot be configured with the same CSI-RS resource ID.
In the embodiment of the application, different first CSI-RS resource sets are configured with different CSI-RS resource IDs; or the like, or, alternatively,
different first CSI-RS resource sets are configured with at least one same CSI-RS resource ID.
Different first CSI-RS resource sets associated with different beam reports are configured for the terminal device by aiming at the network side device, and are associated with different beam reports. Thus, different first CSI-RS resource sets may be configured with different CSI-RS resource IDs; or, different first CSI-RS resource sets may be configured with at least one same CSI-RS resource ID without affecting the beam measurement process.
In an embodiment, a network side device configures two first CSI-RS resource sets for a terminal device: the first CSI-RS resource set (CSI-RS resource set 1) associated with the first beam report and the first CSI-RS resource set (CSI-RS resource set 2) associated with the second beam report may be configured with the same CSI-RS resource ID because they are associated with different beam reports. And the CSI-RS resource indicated by the same CSI-RS resource ID in the CSI-RS resource set 1 and the CSI-RS resource set 2 has the same high-layer configuration parameters.
For example, both CSI-RS resource set 1 and CSI-RS resource set 2 are configured with CSI-RS resource ID of 2, and CSI-RS resource ID of CSI-RS resource set 1 is CSI-RS resource indicated by 2, and CSI-RS resource ID of CSI-RS resource set 2 is CSI-RS resource indicated by 2, having the same high layer configuration parameters.
In the embodiment of the invention, different third CSI-RS resource sets are configured with different CSI-RS resource IDs; or the like, or, alternatively,
different third CSI-RS resource sets are configured with at least one identical CSI-RS resource ID.
Different first CSI-RS resource sets can be configured with different CSI-RS resource IDs, and a third CSI-RS resource set is the first CSI-RS resource set with the retransmission value of off, so that different third CSI-RS resource sets can be configured with different CSI-RS resource IDs without influencing the beam measurement process; or the like, or, alternatively,
since different first CSI-RS resource sets may be configured with at least one same CSI-RS resource ID, and the third CSI-RS resource set is the first CSI-RS resource set with repetition that takes off, different third CSI-RS resource sets may be configured with at least one same CSI-RS resource ID without affecting the beam measurement process.
In the embodiment of the present invention, the high layer signaling further includes: and second configuration information of a fourth CSI-RS resource set associated with the CSI report, wherein the second configuration information comprises a CSI-RS resource ID.
Wherein the second CSI-RS resource set and the fourth CSI-RS resource set are configured with different CSI-RS resource IDs.
And the network side equipment sends second configuration information of a fourth CSI-RS resource set associated with the CSI report to the terminal equipment through high-layer signaling, so that the terminal equipment can perform CSI measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set and feed back the CSI report comprising the CSI measurement result to the network side equipment.
When the network side device configures the reportQuantity in the CSI-Reportconfig as a CSI-related value (e.g., a value other than "CSI-RSRP" or "SSB-Index-RSRP"), the CSI-Reportconfig is used to indicate a CSI report.
The network side equipment also determines second configuration information of a fourth CSI-RS resource set associated with the CSI report through the CSI-ResourceConfig, and further sends the second configuration information to the terminal equipment through a high-level signaling.
In the CSI measurement process, the network side equipment sends CSI-RS resource indicated by CSI-RS resource ID in the fourth CSI-RS resource set to the terminal equipment in the first preset beam direction, the terminal equipment receives CSI-RS resource indicated by CSI-RS resource ID in the fourth CSI-RS resource set in the second preset beam direction corresponding to the first preset beam direction, and carries out CSI measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set, and further feeds back a CSI report including CSI measurement results to the network side equipment.
That is, the terminal device receives the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set in the fixed beam direction, and performs CSI measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set.
Since the terminal device needs to adopt different measurement modes for the second CSI-RS resource set and the fourth CSI-RS resource set, in order to ensure that the terminal device accurately measures the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set or the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set, the second CSI-RS resource set and the fourth CSI-RS resource set are configured with different CSI-RS resource IDs.
If the second CSI-RS resource set and the fourth CSI-RS resource set are configured with the same CSI-RS resource ID, the terminal device cannot accurately perform beam measurement or CSI measurement.
For example, the second CSI-RS resource set and the fourth CSI-RS resource set are each configured with a CSI-RS resource ID of 3.
When the terminal device performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID ═ 3 in the second CSI-RS resource set, the terminal device needs to autonomously switch its receiving direction, and perform beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID ═ 3 in the second CSI-RS resource set in different receiving directions;
when the terminal device performs CSI measurement on the CSI-RS resource indicated by CSI-RS resource ID ═ 3 in the fourth CSI-RS resource set, the terminal device needs to perform CSI measurement on the CSI-RS resource indicated by CSI-RS resource ID ═ 3 in the fourth CSI-RS resource set in the fixed reception direction.
When the network side device sends the CSI-RS resource indicated by CSI-RS resource ID of 3 to the terminal device, the terminal device cannot determine how to measure the CSI-RS resource indicated by CSI-RS resource ID of 3, or cannot measure the CSI-RS resource indicated by CSI-RS resource ID of 3 in a correct measurement manner.
Therefore, the second CSI-RS resource set and the fourth CSI-RS resource set cannot be configured with the same CSI-RS resource ID, so that the terminal device can accurately perform the beam measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set and accurately perform the CSI measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set.
In the embodiment of the invention, different fourth CSI-RS resource sets are configured with different CSI-RS resource IDs; or the like, or, alternatively,
different fourth CSI-RS resource sets are configured with at least one identical CSI-RS resource ID.
For different fourth CSI-RS resource sets configured for the terminal device by the network side device and associated with different CSI reports, different fourth CSI-RS resource sets may be configured with different CSI-RS resource IDs because of being associated with different CSI reports; or, different fourth CSI-RS resource sets may be configured with at least one same CSI-RS resource ID without affecting the CSI measurement process.
In an embodiment, the network side device configures two fourth CSI-RS resource sets for the terminal device: a fourth CSI-RS resource set (CSI-RS resource set 3) associated with the first CSI report and a fourth CSI-RS resource set (CSI-RS resource set 4) associated with the second CSI report, the CSI-RS resource set 3 and the CSI-RS resource set 4 may be configured with the same CSI-RS resource ID due to being associated with different CSI reports. And the CSI-RS resource indicated by the same CSI-RS resource ID in the CSI-RS resource set 3 and the CSI-RS resource set 4 has the same high-layer configuration parameters.
For example, both CSI-RS resource set 3 and CSI-RS resource set 4 are configured with CSI-RS resource ID of 4, and CSI-RS resource ID of CSI-RS resource set 3 is CSI-RS resource indicated by 4, and CSI-RS resource ID of CSI-RS resource set 4 is CSI-RS resource indicated by 4, having the same high layer configuration parameters.
In the embodiment of the invention, the third CSI-RS resource set and the fourth CSI-RS resource set are configured with different CSI-RS resource IDs; or the like, or, alternatively,
the third and fourth CSI-RS resource sets are configured with at least one identical CSI-RS resource ID.
When the terminal equipment carries out measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the third CSI-RS resource set and the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set, the measurement is carried out in a fixed direction. Therefore, the third CSI-RS resource set and the fourth CSI-RS resource set may be configured with different CSI-RS resource IDs; or, the third CSI-RS resource set and the fourth CSI-RS resource set may be configured with at least one same CSI-RS resource ID, which does not affect the measurement process.
In an embodiment, the CSI-RS resource ID in the second CSI-RS resource set cannot be configured in other CSI-RS resource sets.
For example, different second and third CSI-RS resource sets are configured with different CSI-RS resource IDs, and different CSI-RS resource IDs are configured with the second and fourth CSI-RS resource sets.
In another embodiment, different second CSI-RS resource sets are configured with the same CSI-RS resource ID.
For example, the network side device configures two second CSI-RS resource sets for the terminal device: a second CSI-RS resource set (CSI-RS resource set 5) associated with the first beam report, i.e. a CSI-RS resource set associated with the first beam report and having a repetition value of on; a second CSI-RS resource set (CSI-RS resource set 6) associated with the second beam report, i.e. a CSI-RS resource set associated with the second beam report and having a repetition value of on.
Wherein, both the CSI-RS resource set 5 and the CSI-RS resource set 6 are configured with CSI-RS resource ID of 5, and the CSI-RS resource ID of the CSI-RS resource set 5 is the CSI-RS resource indicated by 5, and the CSI-RS resource ID of the CSI-RS resource set 6 is the CSI-RS resource indicated by 5, which have the same high layer configuration parameters.
When the network side equipment sends the CSI-RS resource indicated by the CSI-RS resource ID being 5 to the terminal equipment, the terminal equipment autonomously switches the receiving direction of the terminal equipment, and carries out beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID being 5 in different receiving directions.
According to the technical scheme recorded in the embodiment of the invention, network side equipment sends a high-level signaling to terminal equipment, wherein the high-level signaling comprises the following steps: and the first configuration information of the first CSI-RS resource set associated with the beam report comprises CSI-RS resource IDs, wherein the second CSI-RS resource set is the first CSI-RS resource set with the retransmission value of on, the third CSI-RS resource set is the first CSI-RS resource set with the retransmission value of off, and the second CSI-RS resource set and the third CSI-RS resource set are configured with different CSI-RS resource IDs, so that in the beam training process, the terminal equipment can accurately measure the beam based on the CSI-RS resource indicated by the CSI-RS resource ID in the CSI-RS resource set associated with the beam report.
Fig. 3 is a flowchart illustrating another reference signal resource allocation method according to an embodiment of the present invention. The method is applied to the terminal equipment, and can be as follows.
Step 310, receiving a high-level signaling, where the high-level signaling includes: first configuration information of a first CSI-RS resource set associated with the beam report, wherein the first configuration information comprises a CSI-RS resource ID; the second CSI-RS resource set and the third CSI-RS resource set are configured with different CSI-RS resources, the second CSI-RS resource set is a first CSI-RS resource set with a retransmission value of on, and the third CSI-RS resource set is a first CSI-RS resource set with a retransmission value of off.
In a downlink beam training process of an analog beam forming technology and a digital-analog hybrid beam forming technology, network side equipment sends first configuration information of a first CSI-RS resource set associated with a beam measurement to terminal equipment through high-level signaling, so that the terminal equipment can perform beam measurement based on CSI-RS resource indicated by CSI-RS resource ID in the first CSI-RS resource set, and feeds back the beam measurement result including the beam measurement result to the network side equipment.
Since the terminal device uses L1-RSRP as a measurement result to characterize beam quality during beam measurement, when the network side device configures reportQuantity in CSI-Reportconfig to a value related to L1-RSRP (e.g., "CSI-RSRP" or "SSB-Index-RSRP"), the CSI-Reportconfig is used to indicate beam reporting.
The network side equipment also determines first configuration information of a first CSI-RS resource set associated with the beam report through a parameter CSI-ResourceConfig, and then sends the first configuration information to the terminal equipment through a high-level signaling, wherein the first configuration information comprises a repetition, and the value of the repetition is on or off.
For a first CSI-RS resource set (hereinafter referred to as a "second CSI-RS resource set") whose repetition value is on, the terminal device may determine that the NZP-CSI-RS resources indicated by the CSI-RS resource IDs in the second CSI-RS resource set use the same downlink beam, and each symbol has the same port number;
namely, the network side device sends the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set to the terminal device in the same beam direction, and the terminal device performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set by autonomously switching the receiving direction of the terminal device and feeds back a beam report including the beam measurement result to the network side device.
For a first CSI-RS resource set (hereinafter referred to as a "third CSI-RS resource set") whose repetition value is off, the terminal device cannot determine whether the NZP-CSI-RS resources indicated by the CSI-RS resource IDs in the third CSI-RS resource set use the same downlink beam, and whether each symbol has the same port number;
that is, the network side device sends the CSI-RS resources indicated by the CSI-RS resource IDs in the third CSI-RS resource set to the terminal device in different beam directions in a polling manner, and the terminal device performs beam measurement on the CSI-RS resources indicated by the CSI-RS resource IDs in the third CSI-RS resource set by autonomously switching the receiving direction of the terminal device itself, or the terminal device in the same receiving direction, and feeds back a beam report including a beam measurement result to the network side device.
Since the terminal device needs to adopt different beam measurement modes for the second CSI-RS resource set and the third CSI-RS resource set, in order to ensure that the terminal device accurately performs beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set or the CSI-RS resource indicated by the CSI-RS resource ID in the third CSI-RS resource set, the second CSI-RS resource set and the third CSI-RS resource set are configured with different CSI-RS resource IDs.
In the embodiment of the application, different first CSI-RS resource sets are configured with different CSI-RS resource IDs; or the like, or, alternatively,
different first CSI-RS resource sets are configured with at least one same CSI-RS resource ID.
Different first CSI-RS resource sets associated with different beam reports are configured for the terminal device by aiming at the network side device, and are associated with different beam reports. Therefore, different CSI-RS resource IDs may be configured in different first CSI-RS resource sets; or, different first CSI-RS resource sets may be configured with at least one same CSI-RS resource ID without affecting the beam measurement process.
In the embodiment of the invention, different third CSI-RS resource sets are configured with different CSI-RS resource IDs; or the like, or, alternatively,
different third CSI-RS resource sets are configured with at least one identical CSI-RS resource ID.
Different CSI-RS resource IDs can be configured in different first CSI-RS resource sets, and the third CSI-RS resource set is the first CSI-RS resource set with the retransmission value of off, so that different third CSI-RS resource sets can be configured with different CSI-RS resource IDs, and the beam measurement process cannot be influenced; or the like, or, alternatively,
since different first CSI-RS resource sets may be configured with at least one same CSI-RS resource ID, and the third CSI-RS resource set is the first CSI-RS resource set with repetition that takes off, different third CSI-RS resource sets may be configured with at least one same CSI-RS resource ID without affecting the beam measurement process.
In the embodiment of the present invention, the high layer signaling further includes: and second configuration information of a fourth CSI-RS resource set associated with the CSI report, wherein the second configuration information comprises a CSI-RS resource ID.
Wherein the second CSI-RS resource set and the fourth CSI-RS resource set are configured with different CSI-RS resource IDs.
And the network side equipment sends second configuration information of a fourth CSI-RS resource set associated with the CSI report to the terminal equipment through high-layer signaling, so that the terminal equipment can perform CSI measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set and feed back the CSI report comprising the CSI measurement result to the network side equipment.
When the network side device configures the reportQuantity in the CSI-Reportconfig as a CSI-related value (e.g., a value other than "CSI-RSRP" or "SSB-Index-RSRP"), the CSI-Reportconfig is used to indicate a CSI report.
The network side equipment also determines second configuration information of a fourth CSI-RS resource set associated with the CSI report through the CSI-ResourceConfig, and further sends the second configuration information to the terminal equipment through a high-level signaling.
In the CSI measurement process, the network side equipment sends CSI-RS resource indicated by CSI-RS resource ID in the fourth CSI-RS resource set to the terminal equipment in the first preset beam direction, the terminal equipment receives CSI-RS resource indicated by CSI-RS resource ID in the fourth CSI-RS resource set in the second preset beam direction corresponding to the first preset beam direction, and carries out CSI measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set, and further feeds back a CSI report including CSI measurement results to the network side equipment.
That is, the terminal device receives the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set in the fixed beam direction, and performs CSI measurement on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set.
Since the terminal device needs to adopt different measurement modes for the second CSI-RS resource set and the fourth CSI-RS resource set, in order to ensure that the terminal device accurately measures the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set or the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set, the second CSI-RS resource set and the fourth CSI-RS resource set are configured with different CSI-RS resource IDs.
The second CSI-RS resource set and the fourth CSI-RS resource set cannot be configured with the same CSI-RS resource ID, so that the terminal device can accurately perform beam measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the second CSI-RS resource set and accurately perform CSI measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set.
In the embodiment of the invention, different fourth CSI-RS resource sets are configured with different CSI-RS resource IDs; or the like, or, alternatively,
different fourth CSI-RS resource sets are configured with at least one identical CSI-RS resource ID.
For different fourth CSI-RS resource sets configured for the terminal device by the network side device and associated with different CSI reports, different CSI-RS resource IDs may be configured in the different fourth CSI-RS resource sets because the different fourth CSI-RS resource sets are associated with different CSI reports; or, different fourth CSI-RS resource sets may be configured with at least one same CSI-RS resource ID without affecting the CSI measurement process.
In the embodiment of the invention, the third CSI-RS resource set and the fourth CSI-RS resource set are configured with different CSI-RS resource IDs; or the like, or, alternatively,
the third and fourth CSI-RS resource sets are configured with at least one identical CSI-RS resource ID.
When the terminal equipment carries out measurement based on the CSI-RS resource indicated by the CSI-RS resource ID in the third CSI-RS resource set and the CSI-RS resource indicated by the CSI-RS resource ID in the fourth CSI-RS resource set, the measurement is carried out in a fixed direction. Therefore, different CSI-RS resource IDs may be configured in the third CSI-RS resource set and the fourth CSI-RS resource set; or, the third CSI-RS resource set and the fourth CSI-RS resource set may be configured with at least one same CSI-RS resource ID, which does not affect the measurement process.
In an embodiment, the CSI-RS resource ID in the second CSI-RS resource set cannot be configured in other CSI-RS resource sets.
For example, different second and third CSI-RS resource sets are configured with different CSI-RS resource IDs, and different CSI-RS resource IDs are configured with the second and fourth CSI-RS resource sets.
In another embodiment, different second CSI-RS resource sets are configured with the same CSI-RS resource ID.
For example, the network side device configures two second CSI-RS resource sets for the terminal device: a second CSI-RS resource set (CSI-RS resource set 5) associated with the first beam report, i.e. a CSI-RS resource set associated with the first beam report and having a repetition value of on; a second CSI-RS resource set (CSI-RS resource set 6) associated with the second beam report, i.e. a CSI-RS resource set associated with the second beam report and having a repetition value of on.
Wherein, both the CSI-RS resource set 5 and the CSI-RS resource set 6 are configured with CSI-RS resource ID of 5, and the CSI-RS resource ID of the CSI-RS resource set 5 is the CSI-RS resource indicated by 5, and the CSI-RS resource of the CSI-RS resource set 6 is the CSI-RS resource indicated by 5, which have the same high layer configuration parameters.
When the network side equipment sends the CSI-RS resource indicated by the CSI-RS resource ID being 5 to the terminal equipment, the terminal equipment autonomously switches the receiving direction of the terminal equipment, and carries out beam measurement on the CSI-RS resource indicated by the CSI-RS resource ID being 5 in different receiving directions.
According to the technical scheme recorded in the embodiment of the invention, terminal equipment receives a high-level signaling sent by network side equipment, wherein the high-level signaling comprises the following steps: and the first configuration information of the first CSI-RS resource set associated with the beam report comprises CSI-RS resource IDs, wherein the second CSI-RS resource set is the first CSI-RS resource set with the retransmission value of on, the third CSI-RS resource set is the first CSI-RS resource set with the retransmission value of off, and the second CSI-RS resource set and the third CSI-RS resource set are configured with different CSI-RS resource IDs, so that in the beam training process, the terminal equipment can accurately measure the beam based on the CSI-RS resource indicated by the CSI-RS resource ID in the CSI-RS resource set associated with the beam report.
