Description

Method, device, communication device and storage medium for beam measurement

technical field

The present disclosure relates to the technical field of wireless communication but is not limited to the technical field of wireless communication, and in particular relates to a beam measurement method, device, communication device and storage medium.

Background technique

To perform wireless communication on an unlicensed spectrum, a channel access mechanism of Listen before Talk (LBT) needs to be adopted. Before sending information, it is necessary to perform channel detection through LBT, and only after confirming that the channel is idle can the information be sent. When the LBT detection fails, periodic channel state information reference signals (CSI-RS, Channel-state-information reference signals) for beam management may not be sent, and thus the beam measurement result cannot be updated in time. At this time, beam measurement based on an aperiodic channel state information reference signal (AP-CSI-RS, AperiodicCSI-RS) may be triggered for compensation.

In related technologies, when AP-CSI-RS-based beam measurement is triggered, a large amount of time-frequency domain resources will be occupied, resulting in a waste of time-frequency domain resources.

In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list a plurality of implementation manners to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed independently, or combined with the methods of other embodiments in the embodiments of the present disclosure, and can also be executed alone or in combination It is then executed together with some methods in other related technologies; this is not limited in the embodiment of the present disclosure.

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

Please refer to FIG. 2 , when the LBT detection is successful, the terminal will detect the periodic CSI-RS to obtain the 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 the LBT detection fails, the periodic CSI-RS used for beam management cannot be sent. At this time, since the terminal cannot detect the periodic CSI-RS, it cannot obtain the CSI-RS detection result, thus failing to update the beam measurement result. Due to the mobility of the terminal, the quality of the channel deteriorates, which may eventually lead to a large loss in the throughput of the terminal.

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

In one embodiment, the AP-CSI-RS-based beam measurement and the reporting scheme of the measurement results have restrictions 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 be associated with 64 beams at most. For 52.6 to 71 GHz, the number of corresponding beams is likely to be more than 64, which cannot meet the requirement at this time.

In one embodiment, AP-CSI-RS-based beam measurement and reporting cannot be triggered in a group-based manner, but only AP-CSI-RS-based beam measurement and reporting of a single terminal can be triggered. In this way, the triggering of the DCI needs to occupy a lot of time-frequency domain resources.

In an embodiment, referring to FIG. 4 , beam measurement is performed on terminals using the same periodic CSI-RS, for example, UE1 and UE2 in Group1, and UE3 and UE4 in Group2. For UE1 and UE2 in Group1, periodic CSI-RS cannot be sent due to LBT detection failure, and neither UE1 nor UE2 can perform beam measurement. In this case, an AP-CSI-RS-based beam measurement needs to be triggered at position A for UE1 and UE2 to obtain the latest beam measurement results. At this point, it can be considered to trigger together in a group to save resources.

In one embodiment, beam measurement and reporting based on AP-CSI-RS is triggered through DCI format 0_1 or DCI format0_2. At the same time, the DCI also schedules physical uplink shared channel (PUSCH, Physical Uplink Control Channel) resources for reporting measurement results. There is a CSI request information field in DCI format 0_1 and DCI format 0_2, and each value indicated by the information field corresponds to an aperiodic trigger state. Wherein, one aperiodic triggering state configures one or more AP-CSI-RS sets, and reports configuration corresponding to each reference signal set. In an embodiment, after receiving DCI format 0_1 or DCI format 0_2 including the CSI request information field, the terminal performs beam measurement, and reports the measurement result on the PUSCH scheduled by DCI format 0_1 or DCI format 0_2 according to the reporting configuration.

As shown in FIG. 5, a beam measurement method is provided in this embodiment, wherein the method is performed by a base station, and the method includes:

Step 51, issuing downlink control information DCI;

Among them, the DCI is at least used to: trigger the terminals in the terminal group to perform beam measurement based on the aperiodic channel state information reference signal AP-CSI-RS; the terminal group includes: configured to use the same periodic CSI-RS to perform beam measurement And at least one terminal that has not received the periodic CSI-RS.

Here, the terminal may be, but not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU, RoadSide Unit), a smart home terminal, an industrial sensor 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 for the terminal to access the 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 station.

Here, the base station may deliver DCI to the terminal. Here, the DCI can be DCI format 0_1 or DCI format 0_2.

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

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

In an embodiment, it may be that the periodic CSI-RS cannot be sent when the base station LBT detection fails. It should be noted that when the base station cannot send the periodic CSI-RS, the terminal cannot receive the periodic CSI-RS, and therefore cannot measure the periodic CSI-RS.

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

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

For example, please refer 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 detection is successful. Wherein, T1 is the period for sending the periodic CSI-RS in Example 1; T2 is the period for sending 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 latest 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, and it is determined that beam measurement needs to be performed based on the AP-CSI-RS. In Example 2, t2 is smaller than T2, and it is determined that beam measurement based on the AP-CSI-RS is not required. Certainly, in the embodiment of the present disclosure, the situation that t2 is equal to T2 may be according to the method of Example 1 or the method of Example 2, and details will not be described hereafter.

In an embodiment, using the same periodic CSI-RS to perform beam measurement includes: using the same periodic CSI-RS set to perform beam measurement. Here, each periodic CSI-RS set includes multiple periodic CSI-RSs. In an embodiment, if different terminals are terminals in the same terminal group, the different terminals are all configured to use the same periodic CSI-RS set to perform beam measurement. For example, if terminal 1 and terminal 2 belong to terminal group A, both terminal 1 and terminal 2 are configured to use the same periodic CSI-RS set to perform beam measurement. Of course, in all the embodiments of the present disclosure, the terminals configured to perform beam measurement by using the same periodic CSI-RS set can be regarded as a terminal group. Certainly, terminals having the same periodic CSI-RS set for beam measurement may be classified into one group, or may be classified into two or more groups, which is not limited in this embodiment of the present disclosure. That is, there may be multiple terminal groups, and the same periodic CSI-RS parameters of each terminal group may be the same or different; in this way, it is convenient to further introduce other parameters or variables.

In an embodiment, the beam measurement may be that the terminal measures multiple periodic CSI-RSs, and determines the transmission status of the beam corresponding to the periodic CSI-RS according to the measurement results, so that the base station can select from multiple periodic CSI-RSs according to the transmission status. The beam used for data transmission is determined among the beams. For example, the terminal can measure 3 periodic CSI-RS, the 3 periodic CSI-RS are CSI-RS1, CSI-RS2 and CSI-RS3 respectively, and each periodic CSI-RS corresponds to a CSI-RS in a different direction. The beams are beam 1, beam 2, and beam 3 in sequence. If the detection result indicates that the channel quality of CSI-RS3 is the best, beam 3 can be selected for data transmission.

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

In an embodiment, the DCI may use a terminal group as a trigger unit to trigger all terminals in the corresponding terminal group to perform beam measurement based on the AP-CSI-RS.

In one embodiment, in response to the base station being unable to transmit the periodic CSI-RS, the terminal fails to receive 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 an aperiodic trigger state. Wherein, each aperiodic trigger state indicates one or more AP-CSI-RS sets. Here, the AP-CSI-RS in the set of one or more AP-CSI-RS is used for the terminal to perform AP-CSI-RS measurement. For example, the CSI request field indicates the first aperiodic trigger state, and the first aperiodic trigger state indicates the first AP-CSI-RS set, that is, after the terminal is triggered to perform beam measurement based on the aperiodic AP-CSI-RS, it will Beam measurements may be performed using the AP-CSI-RS in the first AP-CSI-RS set.

In an embodiment, the aperiodic trigger state may also indicate a reporting configuration for reporting the beam measurement results of each AP-CSI-RS set. For example, the CSI request field indicates the second aperiodic trigger state, and the second aperiodic trigger state indicates the second reporting configuration. Here, the reporting configuration may include at least one of the following: reported measurement quantities, reported quantities, and 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 an 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. In this way, in response to the terminal determining the aperiodic trigger state, the AP-CSI-RS set can be determined.

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 an embodiment of the present disclosure, the downlink control information DCI is issued; wherein the DCI is at least used to: trigger the terminals in the terminal group to perform beam measurement based on AP-CSI-RS; wherein the terminal group includes: configured to use the same periodicity At least one terminal for which the CSI-RS performs beam measurement and does not receive the periodic CSI-RS. Here, DCI can trigger the terminals in the terminal group to perform beam measurement based on AP-CSI-RS, that is, DCI can trigger all terminals in the terminal group to perform beam measurement based on AP-CSI-RS at one time. Compared with DCI, it can only trigger a single The manner in which the terminal performs beam measurement based on the AP-CSI-RS can save time-frequency domain resources for sending DCI.

It should be noted that those skilled in the art can understand that the methods provided in the embodiments of the present disclosure may be executed independently, or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

Wherein, the terminal group includes: at least one terminal configured to use the same periodic CSI-RS to perform beam measurement and not receive the periodic CSI-RS. In all embodiments of the present disclosure, terminals configured to perform beam measurement using the same periodic CSI-RS set may be considered as a terminal group.

As shown in FIG. 15, this embodiment provides a beam measurement method, wherein the method is executed by the terminal, and the method includes:

Step 151, receiving DCI;

Among them, DCI is at least used to: trigger the terminals in the terminal group to perform beam measurement based on AP-CSI-RS; the terminal group includes: configured to use the same periodic CSI-RS to perform beam measurement and not receive periodic CSI-RS At least one terminal of RS.

Here, the terminal may be, but not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU, RoadSide Unit), a smart home terminal, an industrial sensor 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 for the terminal to access the 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 station.

Here, the terminal may receive the DCI sent by the base station.

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

In an embodiment, it may be that the periodic CSI-RS cannot be sent when the base station LBT detection fails. It should be noted that when the base station cannot send the periodic CSI-RS, the terminal cannot receive the periodic CSI-RS, and therefore cannot measure the periodic CSI-RS.

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

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

For example, please refer 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 detection is successful. Wherein, T1 is the period for sending the periodic CSI-RS in Example 1; T2 is the period for sending 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 latest 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, and it is determined that beam measurement needs to be performed based on the AP-CSI-RS. In Example 2, t2 is smaller than T2, and it is determined that beam measurement based on the AP-CSI-RS is not required. Certainly, in the embodiment of the present disclosure, the situation that t2 is equal to T2 may be according to the method of Example 1 or the method of Example 2, and details will not be described hereafter.

In an embodiment, if different terminals are terminals in the same terminal group, the different terminals are all configured to use the same periodic CSI-RS set to perform beam measurement. For example, if terminal 1 and terminal 2 belong to terminal group A, both terminal 1 and terminal 2 are configured to use the same periodic CSI-RS set to perform beam measurement.

In an embodiment, the beam measurement may be that the terminal measures multiple periodic CSI-RSs, and determines the transmission status of the beam corresponding to the periodic CSI-RS according to the measurement results, so that the base station can select from multiple periodic CSI-RSs according to the transmission status. The beam used for data transmission is determined among the beams. For example, the terminal can measure 3 periodic CSI-RS, the 3 periodic CSI-RS are CSI-RS1, CSI-RS2 and CSI-RS3 respectively, and each periodic CSI-RS corresponds to a CSI-RS in a different direction. The beams are beam 1, beam 2, and beam 3 in sequence. If the detection result indicates that the channel quality of CSI-RS3 is the best, beam 3 can be selected for data transmission.

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

In an embodiment, the DCI may use a terminal group as a trigger unit to trigger all terminals in the corresponding terminal group to perform beam measurement based on the AP-CSI-RS.

In one embodiment, in response to the base station being unable to transmit the periodic CSI-RS, the terminal fails to receive 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 an aperiodic trigger state. Wherein, each aperiodic trigger state indicates one or more AP-CSI-RS sets. Here, the AP-CSI-RS in the set of one or more AP-CSI-RS is used for the terminal to perform AP-CSI-RS measurement. For example, the CSI request field indicates the first aperiodic trigger state, and the first aperiodic trigger state indicates the first AP-CSI-RS set, that is, after the terminal is triggered to perform beam measurement based on the aperiodic AP-CSI-RS, it will Beam measurements may be performed using the AP-CSI-RS in the first AP-CSI-RS set.

In an embodiment, the aperiodic trigger state may also indicate a reporting configuration for reporting the beam measurement results of each AP-CSI-RS set. For example, the CSI request field indicates the second aperiodic trigger state, and the second aperiodic trigger state indicates the second reporting configuration. Here, the reporting configuration may include at least one of the following: reported measurement quantities, reported quantities, and 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 an 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. In this way, in response to the terminal determining the aperiodic trigger state, the AP-CSI-RS set can be determined.

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.
