At this time, beam measurement based on Aperiodic channel state information reference signals (AP-CSI-RS) can be triggered to make up.

In the related art, when the beam measurement based on the AP-CSI-RS is triggered, a large amount of time-frequency domain resources are occupied, resulting in waste of the time-frequency domain resources.

In order to facilitate understanding of those skilled in the art, the embodiments of the present disclosure set forth a plurality of implementations for clearly illustrating the technical solutions of the embodiments of the present disclosure. Of course, it can be understood by those skilled in the art that the embodiments provided in the present disclosure may be implemented alone, or may be implemented in combination with methods of other embodiments in the embodiments of the present disclosure, or may be implemented alone or in combination with some methods in other related technologies; the disclosed embodiments are not limited thereto.

In order to better understand the technical solution described in any embodiment of the present disclosure, first, an AP-CSI-RS application scenario in the related art is explained:

referring to fig. 2, when the LBT detection is successful, the terminal detects the periodic CSI-RS to obtain a periodic CSI-RS detection result, so that the beam measurement result can be updated based on the periodic CSI-RS.

Referring to fig. 3, when LBT detection fails, periodic CSI-RS for beam management may not be transmitted. At this time, since the terminal cannot detect the periodic CSI-RS, the CSI-RS detection result cannot be obtained, thereby causing failure to update the beam measurement result. Due to the mobility of the terminal, the channel quality deteriorates, and eventually a large loss in the throughput of the terminal may result.

In one embodiment, when the periodic CSI-RS cannot transmit, the AP-CSI-RS based beam measurement may be triggered through the DCI.

In one embodiment, the reporting scheme based on the beam measurement and measurement results of the AP-CSI-RS has a limit on the number of beams. For example, only one AP-CSI-RS set can be triggered for beam measurement at a time, and each AP-CSI-RS set can only associate with 64 beams at most. For 52.6 to 71GHz, the corresponding number of beams is likely to be more than 64, which is not sufficient.

In one embodiment, the AP-CSI-RS based beam measurement and reporting cannot be triggered in a group-based manner, but only by a single terminal. As such, triggering of DCI requires occupying a large amount of time-frequency domain resources.

In one embodiment, please refer to fig. 4, for the terminals that use the same periodic CSI-RS for beam measurement, e.g., UE1 and UE2 in Group1, and UE3 and UE4 in Group 2. For UE1 and UE2 in Group1, both UE1 and UE2 cannot perform beam measurement due to failure of LBT detection and failure to transmit periodic CSI-RS. In this case, the AP-CSI-RS based beam measurements need to be triggered once for UE1 and UE2 at the a position to obtain the latest beam measurement results. At this time, it may be considered to trigger together in a group manner to save resources.

In one embodiment, the AP-CSI-RS based beam measurement and reporting is triggered by DCI format0 _1or DCI format0_ 2. Meanwhile, the DCI also schedules a Physical Uplink Shared Channel (PUSCH) resource for reporting the measurement result. There is a CSI request information field in DCI format0 _1and DCI format0_2, and each value indicated by the information field corresponds to an aperiodic trigger state (aperiodic trigger state). One aperiodic trigger state configures one or more AP-CSI-RS sets and reports configuration corresponding to each reference signal set. In one embodiment, the terminal performs beam measurement after receiving DCI format0 _1or DCI format0 _2including a CSI request information field, and reports a measurement result according to reporting configuration on a PUSCH scheduled by the DCI format0 _1or DCI format 0_2.

As shown in fig. 5, the present embodiment provides a beam measurement method, where the method is performed by a base station, and the method includes:

step 51, issuing downlink control information DCI;

wherein the DCI is at least used for: the method comprises the steps that terminals in a trigger terminal group measure beams based on aperiodic channel state information reference signals AP-CSI-RS; a set of terminals comprising: at least one terminal configured to make beam measurements with the same periodic CSI-RS and not receiving the periodic CSI-RS.

Here, the terminal may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device, and/or a medical device. In one embodiment, the terminal may be a Redcap terminal.

Here, the base station may be an access device of the terminal access network. Here, the base station may be various types of base stations, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

Here, the base station may issue DCI to the terminal. Here, the DCI may be DCI format0 _1or DCI format 0_2.

In one embodiment, the DCI is issued in response to the terminal needing to perform beam measurement based on the AP-CSI-RS.

In one embodiment, the base station determines whether beam measurement based on the AP-CSI-RS is required according to a measurement interval between a time when LBT detection is successful and a time of a previous beam measurement.

In one embodiment, it may be that the periodic CSI-RS cannot be transmitted when the base station LBT detection fails. It should be noted that, when the base station is not able to transmit the periodic CSI-RS, the terminal does not receive the periodic CSI-RS, and therefore, the periodic CSI-RS cannot be measured.

In one embodiment, in response to a measurement interval between a time when LBT detection is successful and a time of a previous beam measurement being greater than or equal to a transmission period of the AP-CSI-RS, the base station determines that beam measurement based on the AP-CSI-RS is required.

In one embodiment, the base station determines that beam measurement based on the AP-CSI-RS is not required in response to a measurement interval between a time when LBT detection is successful and a time of a previous beam measurement being less than or equal to a transmission period of the AP-CSI-RS.

For example, referring to fig. 6, in example 1 and example 2 of fig. 6, the base station is at position a, and the LBT detection fails; at position B, the LBT test was successful. Wherein T1 is a period for transmitting the periodic CSI-RS in example 1; t2 is the period for transmitting the periodic CSI-RS in example 2. t1 is the interval between the time of the last successful LBT detection and the time of the previous beam measurement in example 1; t2 is the interval between the time of the last successful LBT-based detection and the time of the previous beam measurement in example 2. Wherein T1 is greater than T1, and T2 is less than T2. Then in example 1, T1 is greater than T1, it is determined that beam measurements based on the AP-CSI-RS are needed. In example 2, T2 is less than T2, it is determined that beam measurement based on the AP-CSI-RS is not required. Of course, in the embodiment of the present disclosure, the case where T2 is equal to T2 may be according to the method of example 1 or according to the method of example 2, and will not be described again.

In one embodiment, beam measurements are made with the same periodic CSI-RS, including: the same periodic CSI-RS set is used for beam measurements. Here, each periodic CSI-RS set contains a plurality of periodic CSI-RSs. In one embodiment, if different terminals are terminals in the same terminal group, the different terminals are all configured to perform beam measurement using the same periodic CSI-RS set. For example, terminal 1 and terminal 2 belong to terminal group a, then terminal 1 and terminal 2 are both configured to make beam measurements with the same periodic CSI-RS set. Of course, in all embodiments of the present disclosure, terminals configured to make beam measurements using the same periodic CSI-RS set may be considered as one terminal group. Of course, the terminals having the same periodic CSI-RS set for beam measurement may be divided into one group, or may be divided into two or more groups, which is not limited in the embodiments of the present disclosure. That is, there may be a plurality of terminal groups, and the same periodic CSI-RS parameter of each terminal group may be the same or different; in this way, further introduction of other parameters or variables may be facilitated.

In an embodiment, the beam measurement may be that the terminal measures multiple periodic CSI-RSs, and determines, according to a measurement result, a transmission condition for sending a beam corresponding to the periodic CSI-RS, so that the base station determines, according to the transmission condition, a beam used for data transmission from the multiple beams. For example, the terminal may measure 3 periodic CSI-RSs, where the 3 periodic CSI-RSs are CSI-RS1, CSI-RS2, and CSI-RS3, each periodic CSI-RS corresponds to a beam in a different direction, and is sequentially beam 1, beam 2, and beam 3, and if the detection result indicates that the channel quality of the CSI-RS3 is the best, beam 3 may be selected to transmit data.

In one embodiment, the DCI triggers all terminals within the terminal group to make beam measurements based on the AP-CSI-RS. Here, compared with a mode that only a single terminal can be triggered to perform beam measurement based on the AP-CSI-RS by the DCI, occupied time domain and frequency domain resources can be saved.

In one embodiment, the DCI may trigger all terminals within a corresponding terminal group to perform beam measurement based on the AP-CSI-RS in a unit triggered by the terminal group.

In one embodiment, the terminal does not receive the periodic CSI-RS in response to the base station being unable to transmit the periodic CSI-RS.

In one embodiment, the DCI includes a CSI request field, and each value indicated by the CSI request field corresponds to one aperiodic trigger state. Wherein each aperiodic trigger state indicates one or more AP-CSI-RS sets. Here, the AP-CSI-RS in the one or more sets of AP-CSI-RS are used for the terminal to make AP-CSI-RS measurements. For example, the CSI request field indicates a first aperiodic trigger state, and the first aperiodic trigger state indicates a first AP-CSI-RS set, that is, after the terminal is triggered to perform beam measurement based on the aperiodic AP-CSI-RS, the terminal may perform beam measurement using the AP-CSI-RS in the first AP-CSI-RS set.

In one embodiment, the aperiodic trigger state may further indicate a reporting configuration for reporting the result of the beam measurement for each AP-CSI-RS set. For example, if the CSI request field indicates the second aperiodic trigger state, the second aperiodic trigger state indicates the second reporting configuration. Here, the reporting configuration may include at least one of: the reported measurement quantity, the reported quantity and the codebook configuration parameters. After determining the reporting configuration, the terminal may report the measurement result of the beam measurement based on the reporting configuration.

In one embodiment, the mapping relationship between the aperiodic trigger state and the AP-CSI-RS set indicated by the aperiodic trigger state may be stored in the terminal in advance. As such, the set of AP-CSI-RSs may be determined in response to the terminal determining the aperiodic trigger state.

In an embodiment, the mapping relationship between the aperiodic trigger state and the reporting configuration may be stored in the terminal in advance. In this way, in response to the terminal determining the aperiodic trigger state, the reporting configuration can be determined.

In the embodiment of the present disclosure, downlink control information DCI is issued; wherein the DCI is at least to: the terminal in the trigger terminal group carries out beam measurement based on the AP-CSI-RS; wherein, the terminal group includes: at least one terminal configured to make beam measurements with the same periodic CSI-RS and not receiving the periodic CSI-RS. The DCI can trigger the terminals in the terminal group to perform beam measurement based on the AP-CSI-RS, namely the DCI can trigger all the terminals in the terminal group to perform beam measurement based on the AP-CSI-RS at one time, and compared with a mode that the DCI can only trigger a single terminal to perform beam measurement based on the AP-CSI-RS, the time-frequency domain resource for sending the DCI can be saved.

It should be noted that, as can be understood by those skilled in the art, the methods provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in the related art.

As shown in fig. 7, the present embodiment provides a beam measurement method, where the method is performed by a base station, and the method includes:

step 71, responding to the measurement interval being greater than or equal to the sending period of the AP-CSI-RS, and issuing DCI;

wherein, the measurement interval is a time interval between the time when the LBT detection is successful and the time of the previous beam measurement.

Wherein the DCI is at least used for: the method comprises the steps that terminals in a trigger terminal group measure beams based on aperiodic channel state information reference signals AP-CSI-RS; a set of terminals comprising: at least one terminal configured to make beam measurements with the same periodic CSI-RS and not receiving the periodic CSI-RS. In all embodiments of the present disclosure, a terminal configured to make beam measurements using the same periodic CSI-RS set may be considered as one terminal group. Of course, the terminals having the same periodic CSI-RS set for beam measurement may be divided into one group, or may be divided into two or more groups, which is not limited in the embodiments of the present disclosure. That is, there may be a plurality of terminal groups, and the same periodic CSI-RS parameter of each terminal group may be the same or different; in this way, further introduction of other parameters or variables may be facilitated.

In one embodiment, the periodic CSI-RS cannot be transmitted in response to a previous LBT detection failure by the base station. It should be noted that, when the base station is not able to transmit the periodic CSI-RS, the terminal does not receive the periodic CSI-RS, and therefore cannot measure the periodic CSI-RS.

For example, referring again to example 1 in fig. 6, the base station fails the LBT detection at location a and succeeds the LBT detection at location B. Wherein, T1 is a period for transmitting the periodic CSI-RS. t1 is the interval between the time the current LBT detection was successful and the time of the previous beam measurement. Wherein T1 is greater than T1. Then in example 1 the base station determines that beam measurements based on the AP-CSI-RS are needed in response to T1 being greater than T1.

In one embodiment, the periodicity of the periodic CSI-RS configured for the terminal is determined according to a beam change rate of the terminal. In one embodiment, in response to the beam change rate of the terminal being less than a change rate threshold, determining that a periodicity of the periodic CSI-RS is greater than a periodicity threshold; in response to the beam change rate of the terminal being greater than the change rate threshold, determining that a periodicity of the periodic CSI-RS is less than a periodicity threshold.

The measurement results satisfying the predetermined condition are a result G and a result I. The terminal reports the result B, the result D, the result G and the result I on the PUSCH resource in sequence. Namely: the terminal can report the best measurement result and also can report the best N measurement results; or a combination of both.

In an embodiment, the second reporting mode indicates the terminals in the terminal group to report the measurement result satisfying the predetermined condition, which is determined from the measurement results of the plurality of AP-CSI-RS sets.

Wherein the terminal group includes: at least one terminal configured to make beam measurements with the same periodic CSI-RS and not receiving the periodic CSI-RS. In all embodiments of the present disclosure, a terminal configured to perform beam measurement using the same periodic CSI-RS set may be considered as one terminal group. Of course, the terminals having the same periodic CSI-RS set for beam measurement may be divided into one group, or may be divided into two or more groups, which is not limited in the embodiments of the present disclosure. That is, there may be a plurality of terminal groups, and the same periodic CSI-RS parameter of each terminal group may be the same or different; in this way, further introduction of other parameters or variables may be facilitated.

Therefore, the terminals in the terminal group can receive the DCI triggering the terminals in the terminal group to carry out beam measurement based on the aperiodic channel state information reference signal AP-CSI-RS. And therefore, the terminal in the terminal group is triggered to carry out beam measurement based on the aperiodic channel state information reference signal AP-CSI-RS.

For example, referring to fig. 6, in example 1 and example 2 of fig. 6, the base station is at position a, and LBT detection fails; at position B, the LBT test was successful. Wherein T1 is a period for transmitting the periodic CSI-RS in example 1; t2 is the period for transmitting the periodic CSI-RS in example 2. t1 is the interval between the time of the last successful LBT detection and the time of the previous beam measurement in example 1; t2 is the interval between the time of the last successful LBT-based detection and the time of the previous beam measurement in example 2. Wherein T1 is greater than T1 and T2 is less than T2. Then in example 1, T1 is greater than T1, it is determined that beam measurements based on the AP-CSI-RS are needed. In example 2, T2 is less than T2, it is determined that beam measurements based on the AP-CSI-RS are not needed. Of course, in the embodiment of the present disclosure, the case that T2 is equal to T2 may be according to the manner of example 1 or according to the manner of example 2, and is not described again.

In one embodiment, the DCI triggers all terminals within the terminal group to make beam measurements based on the AP-CSI-RS. Here, compared with a mode that DCI can only trigger a single terminal to perform beam measurement based on AP-CSI-RS, occupied time domain and frequency domain resources can be saved.

In one embodiment, the DCI may trigger all terminals within the corresponding terminal group to perform beam measurement based on the AP-CSI-RS in a unit triggered by the terminal group.

In one embodiment, the DCI includes a CSI request field, and each value indicated by the CSI request field corresponds to an aperiodic trigger state. Wherein each aperiodic trigger state indicates one or more AP-CSI-RS sets. Here, the AP-CSI-RS in the one or more sets of AP-CSI-RS is used for the terminal to make AP-CSI-RS measurements. For example, the CSI request field indicates a first aperiodic trigger state, and the first aperiodic trigger state indicates a first AP-CSI-RS set, that is, after the terminal is triggered to perform beam measurement based on the aperiodic AP-CSI-RS, the terminal may perform beam measurement using the AP-CSI-RS in the first AP-CSI-RS set.
