Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order; also, the embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of explanation of the present disclosure, and have no specific meaning in themselves. Thus, "module", "component" or "unit" may be used mixedly.
Currently, an indoor distribution system generally adopts a three-level architecture, namely a Baseband Unit (BBU), a HUB Unit, and a remote Unit (PRRU). The remote units are low-power miniature remote radio frequency modules, and in order to solve the problem of multi-switching during actual deployment, usually, although physical sites of the plurality of remote units are different, the plurality of remote units belong to the same cell logically, and the convergence unit cannot distinguish the traffic on each connected remote unit, so that the traditional energy-saving scheme of the indoor distribution system mainly performs timed power-down on equipment according to experience. However, the scheme has poor flexibility, and the situation that the equipment still works without service or the equipment is in a power-off state with service easily occurs, so that the comprehensive power saving effect is poor.
In order to solve the above problems, the embodiment of the present disclosure optimizes the energy saving effect of the indoor distribution system by using a hierarchical energy saving manner in combination with a remote unit refinement energy saving manner, and specifically, the embodiment of the present disclosure determines the traffic of the baseband unit, the convergence unit, and the remote unit step by step to save energy of the indoor system step by step. The service volumes of the baseband unit and the convergence unit can directly acquire data; the remote unit traffic volume obtains the attributive terminal volume under each remote unit by opening the RSRP reported by the remote unit statistical terminal in turn, and then obtains the traffic volume.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an energy saving method for an indoor distribution system according to an embodiment of the present disclosure, where the method includes steps S101 to S106.
In step S101, it is detected whether the data amount of the baseband unit of the indoor distribution system is greater than a first preset threshold, if not, step S102 is executed, otherwise, step S103 is executed.
In this embodiment, the data amount of the baseband unit may be directly obtained from the baseband unit, and then it is detected whether the data amount is less than or equal to a first preset threshold, where the data amount of the baseband unit may be a parameter that can reflect a service load, such as a traffic, an uplink/downlink PRB (Physical Resource Block) utilization rate, a CCE (Control Channel Element) utilization rate, and a Radio Resource Control (RRC) connection rate.
It should be noted that values of the threshold (for example, the first preset threshold, the second preset threshold, and the like) appearing in this embodiment may be the same or different, and those skilled in the art can adaptively set data of different thresholds in combination with the prior art and practical application.
In step S102, the baseband unit, the convergence unit of the indoor distribution system, and a plurality of remote units of the indoor distribution system are respectively turned off to save energy.
In particular, if it is detected that the amount of baseband data is less than or equal to a first preset threshold value, for example a threshold value Γ1The baseband unit, the convergence unit and the remote unit are all turned off to save energy; otherwise, the energy saving is not turned off, and in the embodiment, the energy saving at the micro base station level is realized by aiming at the energy saving mode of the data volume of the base station, so that the maximum energy saving effect is obtained.
In step S103, it is detected whether the data amount of the aggregation unit is greater than a second preset threshold, if not, step S104 is executed, otherwise, step S105 is executed.
In this embodiment, the data is obtainedThe aggregation unit data can obtain parameters such as data size and the like. The acquisition mode may be directly extracting the data from the aggregation unit, or obtaining the data volume belonging to the aggregation unit by a certain method, and then detecting whether the data volume is less than or equal to a second preset threshold value, such as a threshold value Γ2。
In step S104, the convergence unit and the remote units are respectively turned off to save energy.
In this embodiment, if the aggregation unit detects that the data amount is less than or equal to the threshold Γ2If the energy is saved, the far-end units of the convergence unit are all turned off, otherwise, the energy is not turned off, and the energy saving of the convergence unit level is realized.
It is understood that a number of remote units refers to all remote units connected to the convergence unit.
In step S105, it is detected whether the respective data amount of the plurality of remote units is greater than a third preset threshold, if the data amount of one or some of the remote units is not greater than the third preset threshold, step S106 is executed, otherwise, the process is ended, and the energy saving operation for the remote units is completed or the remote units are not performed by using the prior art.
In an indoor distribution system, a convergence unit is usually connected with a plurality of remote units, and this embodiment respectively detects data volumes of the remote units and respectively turns off energy saving according to preset rules, thereby ensuring network quality stability during energy saving while realizing energy saving optimization effect.
Specifically, parameters such as the size of the data volume can be obtained through the acquired remote unit data. The acquisition mode may be to directly extract data from the remote unit, or to determine the amount of data attributed to the remote unit by a certain method. In some embodiments, by determining the data amount attributed to the remote unit, the user attribution may be determined by using SSB-RSRP (Synchronization Signal Block-Reference Signal Receiving Power) measurement data reported by the terminal, or may be determined by using CSI-RSRP (Channel State Information-Reference Signal Receiving Power) measurement data reported by the terminal, which is described in detail later.
In step S106, the remote units are respectively turned off according to a preset rule to save energy.
It should be noted that, in this embodiment, the preset rule is a rule for determining to turn off or not to turn off the power saving for the data volume of a plurality of remote units, and in some embodiments, the preset rule is determined according to the adjacent remote units of the remote units. In the embodiment, the granularity of the energy-saving equipment is refined by setting the specific energy-saving mode of the remote unit, and a precise energy-saving strategy is realized, so that the energy-saving effect is optimized to the greatest extent.
Referring to fig. 2, a skilled person first sets an energy saving determination period, and when entering the energy saving determination period, step a first obtains baseband data and determines whether a baseband data amount/e.g. RRC connection number is less than or equal to 0, and if so, enters a micro-distribution level energy saving; otherwise, step b, acquiring the data of the convergence unit, and judging whether the data volume of the convergence unit/for example the RRC connection number is less than or equal to 0, if so, entering the level of the convergence unit for saving energy; otherwise, step c, obtaining the data of the remote unit, and judging whether the data volume/for example, the RRC connection number of the remote unit is less than or equal to 0, if so, entering the remote unit level for energy saving, otherwise, ending or detecting again until the energy saving judging period is ended.
Referring to fig. 3, fig. 3 is a schematic flow chart of another energy saving method for an indoor distribution system according to an embodiment of the present disclosure, where on the basis of the previous embodiment, the present embodiment discloses a specific obtaining manner of a data volume of a remote unit, and specifically, in addition to the above steps S101 to S106, the method further includes:
in step S301, the home terminals corresponding to the remote units are respectively identified.
In this embodiment, the home terminal is the terminal used for calculating the data amount of the remote unit, and specifically, as shown in fig. 4, step S301 includes steps S301a-S301 e.
Step S301 a: sequentially starting the remote units;
step S301 b: each time a remote unit is turned on, obtaining respective measurement report values of all terminals in the network, which can measure signals of the remote unit, wherein the measurement report values are obtained by measuring, after the terminals in the network, which can measure signals of the remote unit (i.e., the remote unit turned on each time, receive an SSB (Synchronization Signal Block) Signal or a CSI (Channel State Information) Signal.
Step S301 c: sequentially obtaining reference signal receiving powers of all terminals in the network at the plurality of remote units respectively based on the measurement report values obtained each time;
step S301 d: respectively identifying corresponding remote units of which all terminals in the network respectively obtain the maximum reference signal received power based on the reference signal received power; and the number of the first and second groups,
step S301 e: and all the terminals which obtain the maximum reference signal received power at each remote unit are respectively used as the home terminals corresponding to the remote units.
It should be noted that, in the above steps S301a-S301e, the method of determining attribution according to the RSRP measurement result reported by the terminal is used. The RSRP is one of the methods described in the embodiments, and in some embodiments, the device may also directly obtain the data volume of the remote unit by a certain method, which is not set in this embodiment.
With reference to fig. 5, a specific implementation of obtaining the home terminal of the remote unit for two different signals includes the following steps:
step 1) acquiring an SSB/CSI signal after entering a statistical period.
Specifically, for different forms of SSB/CSI measurement, parameters need to be configured first, where a terminal reports an SSB-RSRP to determine a parameter configuration mode to which a user belongs:
the following parameters are configured in the higher layer CSI-ReportConfig IE:
-configuring periodic transmission of CSI by reportConfigType reporting type parameter configuration, periodic, and reportSlotConfig parameter configuration CSI reporting period and offset.
The reportQuantity parameter is configured as ssb-Index-RSRP.
The method comprises the following steps of judging the parameter configuration mode of user attribution through the terminal reporting CSI-RSRP:
configuring the following parameters in the higher layer CSI-report config IE
-configuring periodic transmission of CSI by using reportConfigType parameter configuration and periodic CSI reporting period and offset by using reportSlotConfig parameter configuration
-reportQuantity parameter configuration as csi-RSRP
-parameter repeption configuration in higher layer NZP-CSI-RS-resourcesettie as on
-configuring the CSI sending period and offset by the parameter CSI-ResourceProeriodicityAndOffse in the higher layer NZP-CSI-RS-Resource IE
And 2) calculating the RSRP.
Specifically, the remote unit PRRU is first numbered, PRRU _ index ═ 0,1, …, N-1. The remote unit PRRU is turned on in turn, and the starting system frame number of the remote unit PRRU is calculated.
Since the SSB completes transmission in a 5ms window in one SS burst set period, the remote units need to be turned on in turn according to the SS burst set period, that is, one remote unit is turned on in each SSB period, and taking the first system frame number SFN as an example, the initial system frame number PRRU _ SFN _ on ═ SFN + PRRU _ index ×) T that each remote unit is turned on is calculatedSSB。
Step 3) find max (PRRU _ index) and return to perform step 2) during the incomplete PRRU traversal.
And 4) judging whether the maximum measurement times in the period are counted or not after completing the PRRU traversal. In the statistical period, the maximum measurement times can be set, and each measurement is defined as finishing one time of PRRU alternate opening and terminal reporting.
And step 5) in a counting period, counting SSB-RSRP corresponding to SS burst set periods started by each remote unit and reported by each terminal to obtain a cell ID, a user ID, a PRRU _ index and a L1-RSRP mapping table.
And 6) sequencing the RSRP according to the UE ID to obtain max (RSRP) and a PRRU _ index and UE ID mapping table, and finishing the counting period.
Specifically, L1-RSRP is sorted by using user ID as a key to obtain a set of mapping vectors, where, for example, user ID ═ i, [ user ═ isi,vector_RSRP,vector_pRRU,cellID]Wherein
vector_pRRU＝[pRRU0,pRRU1,L,pRRUM-1]M is the number of pRRUs of RSRP measured under the userID, and M is less than or equal to N; and meanwhile, obtaining a mapping table of M and N, wherein M belongs to M, and N belongs to N. And (3) solving the maximum value of the sorted vector to RSRP, namely solving max (vector _ RSRP) of userID (i), and obtaining the corresponding PRRU _ index when the measured SSB-RSRP is maximum.
In step S302, the data amount of all identified home terminals each at its home remote unit is respectively acquired.
In step S303, the data amount of each of the remote units to which all the home terminals belong is used as the data amount of each of the plurality of remote units.
Further, in order to further optimize the energy saving effect of the remote unit, when identifying the home terminal, the step S303 includes the following steps:
and screening all the terminals which obtain the maximum reference signal receiving power and the power value of which is greater than a fourth preset threshold value at each remote unit, and respectively taking the terminals as the attributive terminals corresponding to the remote units.
Further, this embodiment, by dividing adjacent units of the remote unit, and performing resource compensation on the corresponding remote unit by using the adjacent units, so as to achieve energy saving rationalization and meet the communication requirement of the user, specifically, after identifying respective corresponding affiliations of the plurality of remote units (i.e., step S301), the terminal further includes the following steps:
for the attribution terminals corresponding to the plurality of remote units, screening out the first remote units of which the obtained reference signal received power is greater than a fourth preset threshold value from the other remote units except the attribution remote units; and the number of the first and second groups,

for a remote unit with a data volume not greater than a third preset threshold, if the sum of the data volume of the remote unit and the data volume of an adjacent remote unit of the remote unit is less than a fifth preset threshold, turning off the remote unit to save energy, and keeping the awakening state of the adjacent remote unit of the remote unit.
It is understood that, the neighboring remote units determined by the present embodiment are the co-covering neighboring remote units, and the reference signal received power RSRP of the first other remote unit is greater than the fourth predetermined threshold Γrsrp_prruAnd less than the maximum reference signal received power max (rsrp) of its respective remote unit.
Further, in order to satisfy the compensation effect of the adjacent remote units on the energy-saving remote units and simultaneously ensure that the adjacent remote units satisfy the resource requirements of the adjacent remote units, this embodiment further includes the following steps after the first remote unit is screened out for the home terminal corresponding to each of the plurality of remote units:
continuously screening second remote units with the total number of access terminals larger than a fifth preset threshold value from the first remote units screened aiming at the home terminals corresponding to the remote units; and the number of the first and second groups,
and respectively taking the second remote units screened out aiming at the home terminals corresponding to the remote units as the adjacent remote units of the remote units.
In some embodiments, based on the energy saving mode of the adjacent remote units, a wake-up mechanism is further correspondingly proposed, and according to the traffic of every two adjacent remote units, the remote units are woken up according to a certain rule, which may refer to the specific example below and will not be described herein again.
In an embodiment, to achieve optimization of energy saving effect and satisfy communication quality of a terminal at the same time, in this embodiment, in an adjacent area without common coverage, to ensure that network coverage maintains an awake state of at least one remote unit without energy saving, specifically, the method further includes the following steps:
for the attribution terminals corresponding to the plurality of remote units, screening out a third remote unit of which the obtained reference signal received power is not greater than a fourth preset threshold value from the other remote units except the attribution remote unit;
respectively taking the third remote units screened out aiming at the home terminals corresponding to the remote units as non-adjacent remote units of the remote units;
the respectively switching off the plurality of remote units according to the preset rule is energy-saving, and the method comprises the following steps:
turning off and saving energy for the remote units with the data volume not larger than a third preset threshold; and, always maintaining the awake state of non-adjacent ones of the remote units.
It will be appreciated that in this embodiment, non-adjacent remote units are uncovered adjacent remote units.
To facilitate understanding of the present embodiment, the present embodiment is exemplified as follows, and shown in conjunction with fig. 6, and includes a baseband unit 61, a convergence unit 62, and three remote units 63, wherein the three remote units are respectively identified as pRRU0、pRRU1And pRRU2，

Taking the first system frame number SFN as an example, the starting system frame number pRRU _ SFN _ on ═ SFN + pRRU _ index ═ TSSB of each remote unit activation is calculated.
And setting the maximum statistical measurement frequency in the statistical period to be 1, namely, the base station alternately starts the pRRU once and only measures and reports the RSRP once corresponding to each pRRU terminal. And counting SSB-RSRP reported by the terminal and corresponding to SS burst set periods started by each remote unit to obtain cell ID, user ID, pRRU _ index and L1-RSRP mapping tables.

The remote units pRRU are numbered, and in this embodiment, pRRU _ index under each aggregation unit is [0,1,2 ].
Alternately starting the remote units pRRU and calculating the starting system frame number of the remote units pRRU
Since the SSBs complete transmission within a 5ms window in one SS burst set period, the remote units need to be turned on in turn according to the SS burst set period, that is, one remote unit is turned on in each SSB period, and an initial system frame number pRRU _ SFN _ on, which is SFN + pRRU _ index TSSB, of each remote unit is calculated by taking the first system frame number SFN as an example.
And counting SSB-RSRP reported by the terminal and corresponding to SS burst set periods started by each remote unit to obtain cell ID, user ID, pRRU _ index and L1-RSRP mapping tables.
The RSRPs are ordered by user ID, i for example, [ user ═ i [, [ user ]i,vector_RSRP,vector_pRRU,cell ID]Wherein
And (3) the sorted vectors are used for solving the maximum value of the RSRP, namely, the userID is equal to i, and max (vector _ RSRP) is solved, when the measured SSB-RSRP is maximum, the corresponding pRRU _ index is 0, and the terminal is judged to belong to pRRU 0.
1.3.3 energy saving judgment
Judging the traffic volume of pRRU0 and pRRU1, and if the traffic volume of pRRU0 is less than Γ3The sum of the pRRU0 traffic and the pRRU1 traffic is below a threshold
It is determined that pRRU0 can save power and pRRU1 does not save power as a compensating remote unit.
13.4. The wake-up mechanism is a mechanism that,
if the remote unit pRRU0 performs a power saving task, pRRU1 compensates the remote unit for the energy saving task and determines whether to wake up pRRU0 by monitoring traffic for real-time data. When the data volume of pRRU1 is larger than the threshold
Indicating that pRRU1 cannot afford the traffic of pRRU 0; or a terminal measurement RSRP of the home pRRU1 is below a threshold Γrsrp_lowAnd the number of terminals meeting the condition is more than the threshold gammarsrp_usernumWhen so, the power saving task is ended and the pRRU0 is awakened.
