[0062] like Figure 1 FIG2 is a flowchart of a method for configuring a base station beam channel sounding reference signal according to an embodiment of the present invention. Figure 1The embodiment of the present application provides a base station beam channel sounding reference signal configuration method, and specifically comprises the following steps.
[0063] S101, positioning measurement is performed on the multiple target terminals by the target base station, the target terminals are grouped according to the positioning measurement result, and multiple user groups are obtained.
[0064] Specifically, when the geographical positions of multiple UEs (user terminals) remain close, generally, the channel conditions of the UEs are also relatively close, for such UEs, the base station can regard them as a user group and implement similar beam management.
[0065] As Figure 2 It is a step flow chart of step S101 provided by the embodiment of the present application, and the step S101 is described in detail with reference to Figure 2 Further, as an optional implementation, the positioning measurement is performed on the multiple target terminals by the target base station, the target terminals are grouped according to the positioning measurement result, and multiple user groups are obtained, and specifically, the step S101 comprises the following steps.
[0066] S1011, positioning measurement is performed on the multiple target terminals by the target base station, and terminal position information of each target terminal at multiple historical moments is obtained.
[0067] S1012, the terminal distance between two target terminals at each historical moment is determined according to the terminal position information.
[0068] S1013, when the terminal distance between the two target terminals at each historical moment is less than or equal to a preset distance threshold, it is determined that the corresponding two target terminals are similar terminals.
[0069] S1014, the target terminals are grouped to obtain multiple user groups, so that the multiple target terminals in each user group are similar terminals.
[0070] Specifically, the base station performs positioning on the terminal, and the positioning can be performed by a method based on UTDOA (Uplink Time Difference of Arrival) or AOA (Angle of Arrival) in the 3gpp technical specification. When the base station determines that a plurality of UEs remain close in position within a period of time, the UEs can be regarded as a group.
[0071] In some optional embodiments, the basis for dividing the user groups can also be:
[0072] 1) The intensity variation law of the same reference beam / signal measured by the UE is close enough, or the UE position variation law is close enough from the reference beam / signal at different moments or frequencies;
[0073] 2) the angle of arrival of the uplink signal at each time is close enough;
[0074] wherein the intensity, angle of arrival can be based on measurements or post-measurement estimates.
[0075] An important step of beam management is the measurement of the sounding reference signal by the base station, so as to understand the channel information. Figure 3 As shown in FIG. 1, a schematic diagram of the present embodiment is provided for a plurality of target terminals in a user group to independently send sounding reference signals. When each UE in the group independently sends a sounding reference signal, a large amount of uplink time-frequency resources will be occupied. However, the channel derived from the measurement results of the UEs in one group is similar. That is, such a configuration consumes a large amount of resources, and the benefit of obtaining channel knowledge by the base station is limited.
[0076] Therefore, it is a more practical way to complete the measurement of the sounding reference signal under the premise of reducing resource consumption. As shown in FIG. 2, a schematic diagram of the present embodiment is provided for a plurality of target terminals in a user group to send joint sounding reference signals. In the present embodiment, the base station regards a plurality of user equipments with close geographical positions as a user group, and configures joint sounding reference signals for the user equipments in the group. The coordination of the sounding reference signal configuration can be based on the state of the user equipment. The user equipments in the group with a high probability of maintaining a connected state can be configured with higher density sounding reference signals in the time domain, frequency domain, spatial domain, and code domain. Figure 4 S102, predicting connection state probability distribution information of each target terminal in the user group at a target time, and determining the SRS proportion of each target terminal in the corresponding user group according to the connection state probability distribution information.
[0077] Further, as an optional implementation, the connection state probability distribution information includes a first connection state probability value, a second connection state probability value, and a third connection state probability value. The first connection state probability value represents the probability of the target terminal being in a non-connected state. The second connection state probability value represents the probability of the target terminal maintaining a connected state but leaving the corresponding user group. The third connection state probability value represents the probability of the target terminal maintaining a connected state and not leaving the corresponding user group.
[0078] As shown in FIG. 3, a step flowchart of step S102 is provided according to the present embodiment. As shown in FIG. 4, further, as an optional implementation, the prediction of the connection state probability distribution information of each target terminal in the user group at the target time specifically includes:
[0079] Figure 5 As shown in FIG. 3, a step flowchart of step S102 is provided according to the present embodiment. As shown in FIG. 4, further, as an optional implementation, the prediction of the connection state probability distribution information of each target terminal in the user group at the target time specifically includes: Figure 5 S1021, determining whether a non-active timer of the target terminal is in an expired state at a current time, the current time being a previous time of the target time.
[0080]
[0081] S1022, when the inactivity timer is in the timeout state at the current time, determining that the corresponding first connection state probability value is 1, and determining that the corresponding second connection state probability value and the third connection state probability value are both 0;
[0082] S1023, when the inactivity timer is not in the timeout state at the current time, determining that the corresponding first connection state probability value is 0, and obtaining the first terminal position of the target terminal at the current time and the second terminal position of other target terminals in the user group at the current time;
[0083] S1024, determining the terminal positioning center point of the user group at the current time according to the first terminal position and the second terminal position, and obtaining the second connection state probability value and the third connection state probability value by predicting the distance between the first terminal position and the terminal positioning center point.
[0084] Further, as an optional implementation, when the inactivity timer is not in the timeout state at the current time, the second connection state probability value and the third connection state probability value are obtained by the following formula:
[0085]
[0086]
[0087] wherein, P i2 represents the second connection state probability value, P i3 represents the third connection state probability value, x i represents the distance between the first terminal position and the terminal positioning center point, and k represents a preset adjustment parameter.
[0088] Specifically, the base station coordinates the SRS configuration of the UEs in the group. The ratio of the number of equivalent time-frequency resources RE occupied by UEi (i∈[1,N], N is the number of UEs in the group) to the total number of equivalent time-frequency resources occupied by the group is defined as the SRS proportion of UEi. For UEs with high probability of remaining in the connection state and not leaving the group, configuring a higher SRS proportion can more efficiently utilize resources.
[0089] The joint SRS can be sent by the connected state UEs in the group, and multiplexed through time division / frequency division / code division / space division, etc.
[0090] In the time division / frequency division manner, the number of occupied time-frequency resources can be directly counted.
[0091] In the code division / space division manner, the number of equivalent time-frequency resources occupied by SRS is converted according to the number of code words / space division layers. For example, Figure 8The figure shows a schematic diagram of the number of equivalent time-frequency resources occupied by the target terminal in the code division / space division mode provided by an embodiment of the present invention. UE1 and UE2 occupy 12 and 4 equivalent time-frequency resources respectively.
[0092] The base station may use the UE status as a basis for allocating the amount of SRS resources.
[0093] At a certain moment, a connected UEi in a group may be in the following three states:
[0094] 1) Entering the non-connected state, the probability is estimated to be P i1 ;
[0095] 2) In the connected state, the probability of leaving the group is estimated to be P i2 ;
[0096] 3) In the connected state, the probability of not leaving the group is estimated to be P i3 .
[0097] Should satisfy P i1 +P i2 +P i3 = 1. After the inactivity timer expires, P i1 =1, otherwise P i1 = 0. Define the degree of dissimilarity between UEi and the UE measurement results or positioning in the group as x i , x i It is a positive number, for example, it can be represented by the distance between UEi and the positioning center point of the UE in the group. i2 According to x i To estimate, for example Where k is a settable positive number. i3 Can be obtained by P i1 and P i2 It can be deduced that P i3 A larger UEi is configured with a higher SRS ratio.
[0098] like Figure 6 FIG. 1 is another flow chart of step S102 provided in an embodiment of the present invention, referring to FIG. Figure 6 As an optional implementation, determining the SRS proportion of each target terminal in the corresponding user group according to the connection state probability distribution information specifically includes:
[0099] S1025. Determine a third connection state probability value corresponding to each target terminal according to the connection state probability distribution information;
[0100] S1026: Determine an SRS proportion of each target terminal according to the third connection state probability value, such that the SRS proportion is positively correlated with the third connection state probability value.
[0101] Specifically, for example, 3 UEs in a certain user group, the connected state probability distribution information is shown in Table 1 as follows:
[0102] P i1 ]]> P i2 ]]> P i3 ]]> UE1 0 0.1 0.9 UE2 0 0.4 0.6 UE3 0 0.4 0.6
[0103] Table 1
[0104] It can be seen that the P of UE1 is the largest, so the base station can configure a higher SRS proportion for UE1, for example, the SRS proportions of UE1, UE2 and UE3 are 0.5, 0.25 and 0.25 respectively. i3
[0105] S103, coordinating and configuring joint sounding reference signals of the corresponding user group according to the SRS proportion, so that the number of equivalent time-frequency resources occupied by each target terminal in the joint sounding reference signal is positively correlated with the probability that the target terminal remains in the connected state and does not leave the corresponding user group.
[0106] As Figure 7 shown is a step flowchart of step S103 provided by the embodiment of the application, with reference to Figure 7 , further as an optional implementation, coordinating and configuring joint sounding reference signals of the corresponding user group according to the SRS proportion, which specifically includes:
[0107] S1031, determining the total number of equivalent time-frequency resources occupied by the user group;
[0108] S1032, determining the number of equivalent time-frequency resources occupied by each target terminal in the user group according to the SRS proportion and the total number of equivalent time-frequency resources;
[0109] S1033, configuring the joint sounding reference signal according to the number of equivalent time-frequency resources.
[0110] Specifically, after determining that the SRS proportions of UE1, UE2 and UE3 are 0.5, 0.25 and 0.25 respectively, the total number of equivalent time-frequency resources occupied by the user group is determined, and the number of equivalent time-frequency resources occupied by each UE can be obtained by multiplying the corresponding SRS proportion. As Figure 9 shown is a schematic diagram of comb-shaped structure joint sounding reference signal configured according to the SRS proportion provided by the embodiment of the application, taking comb2 and comb4 comb-shaped structure SRS as an example, UE1 can be configured as comb2, and UE2 and UE3 can be configured as comb4, at this time, the SRS proportions of UE1, UE2 and UE3 are 0.5, 0.25 and 0.25 respectively.
[0111] The method flow and implementation process of the embodiment of the application are described above. It can be understood that the embodiment of the application divides user groups according to the positioning measurement results of the target terminals, and configures joint sounding reference signals based on the connection state probability distribution information of each target terminal in the user group, so that the equivalent time-frequency resources of the joint sounding reference signals are as much as possible to be utilized by the target terminals in the connection state, thereby reducing the wireless network resources occupied by the sounding reference signals, reducing the beam management overhead, and improving the wireless resource utilization rate.
[0112] As shown in Figure 10 Fig. 1 is a structural schematic diagram of a base station beam channel sounding reference signal configuration system provided by an embodiment of the application, referring to Figure 10 The embodiment of the application provides a base station beam channel sounding reference signal configuration system, which comprises:
[0113] A user group determination module is configured to perform positioning measurement on a plurality of target terminals by a target base station, group the target terminals according to the positioning measurement results, and obtain a plurality of user groups.
[0114] An SRS proportion determination module is configured to predict the connection state probability distribution information of each target terminal in the user group at a target time, and determine the SRS proportion of each target terminal in the corresponding user group according to the connection state probability distribution information.
[0115] A coordination configuration module is configured to coordinate and configure the joint sounding reference signal of the corresponding user group according to the SRS proportion, so that the number of equivalent time-frequency resources occupied by each target terminal in the joint sounding reference signal is positively correlated with the probability that the target terminal remains in the connection state and does not deviate from the corresponding user group.
