Description

RADIO RESOURCE MANAGEMENT MEASUREMENT AND RADIO RESOURCE CONTROL PROTOCOL FOR LICENSED SHARED ACCESS

CROSS-REFERENCE TO RELATED APPLICATIONS The present application claims the benefit of U.S. Provisional Application No. 62/200,923 filed Aug. 4, 2015 (Docket No. P87711Z). Said Application No. 62/200,923 is hereby incorporated herein by reference in its entirety.

BACKGROUND

In a licensed shared access (LSA) system, usage of spectral resources is not exclusive but rather governed through different tiers of access classes. The highest priority is reserved for the incumbent user, for example program making and special events (PMSE) services, amateur radio, or terrestrial, aeronautical and naval radar. In addition to the incumbent user, national regulatory authorities (NRAs) may also award licenses to mobile network operators (MNOs), hospitals, local governments, or any other public safety agency for the same spectral resources. Such users may be referred to as the LSA licensees or priority access licensees (PALs). Depending on the sharing framework, an additional third access class may be defined for general authorized access (GAA). GAA differs from traditional unlicensed technologies such as Wi-Fi, Bluetooth or license-assisted access (LAA) in cellular networks in that the spectrum is not unlicensed. Rather, unlicensed user equipment (UE) is allowed to opportunistically use licensed spectrum when the spectrum is otherwise idle.

In an LSA system, secondary users of lower priority, for example mobile network operators (MNOs), self-monitor the aggregated interference they cause towards a primary user of higher importance, the incumbent user. The aggregated interference is the sum of the received power from all base stations or cells in radio access network (RAN) of the MNO, and the interference generally depends on the geographic location where it is measured due to pathloss, shadowing, penetration losses, and so on. Currently, user equipment (UE) only reports the reference signal received power (RSRP) or/and reference signal received quality (RSRQ) per cell on a given carrier frequency.

In legacy systems, UEs report measurements based on triggers designed for mobility or based on periodic reporting. These legacy triggers compare measurement results from single cells, either relatively among each other or absolutely to configured thresholds. Triggers for LSA, however, do not exist in current specifications. DESCRIPTION OF THE DRAWING FIGURES

Referring now to FIG. 1, a diagram of a network implementing licensed shared access (LSA) in accordance with one or more embodiments will be discussed. As shown in FIG. 1, network 100 may be operating in accordance with a Third Generation Partnership Project (3GPP) standard including a Long Term Evolution (LTE) standard or an LTE Advanced (LTE- A) standard. In one or more embodiments, user equipment (UE) 114 may communicate with a first cell (CELL 1) 116 in a licensed shared access (LSA) area 112 on licensed shared access spectrum resources. In one or more embodiments, cell 116 may be the primary cell or the serving cell for UE 114, and may comprise an evolved NodeB (eNB) in one or more embodiments, although the scope of the claimed subject matter is not limited in this respect. In the LSA area 112 shown in FIG. 1, UE 114 potentially may be able to connect with one or more additional cells, such as a second cell (CELL 2) 118, a third cell (CELL 3) 120, up to an Nth cell (CELL N) 122. UE 114 occasionally may obtain measurements for one or more other neighbor cells, for example during designated measurement gaps as set forth in an LTE standard. UE 114 reports the measurements back to the network 100 for so that the network 100 can determine if the UE 114 should switch to a secondary cell as the serving cell for UE 114.

In an LSA system, UE 114 may be a secondary user of the LSA band in LSA area 112. As a secondary user of the LSA band, UE 114 is responsible to self-monitor the aggregated interference that may be caused toward incumbent user of the LSA band. The aggregated interference is the sum of the received power from all of the base stations or cells in LSA area 112. The aggregate interference may be defined as follows: Let Ρ %Χ}Ϊ ? -»Ά be the received power from cell c at location #— fr y ∑]^T. Further, let i¾:I³→i be the aggregated interference from i¾ cells at location *.·

Let ίξ^χ') be a linear estimate of Ιζ^χ% namely, («} =^■ 2§f ½_£C* ¾) where ¾(*) is the number of known measurement reports ί{^χ for the aggregated interference at locations ξχ ^® in the neighborhood of *. Let w e} - lw_s{x} ^■- ¾¾^ ?)3^Τ and = — *·

Then:

Hence, given sub-optimal weights w(x) as well as a sub-optimal number of measurement reports one can obtain estimates of the aggregated interference ΐζχ) = ν^-ξ }Ιζ } for arbitrary locations .r. The objective of interference self-monitoring in a LSA system is to guarantee that the aggregated interference, or an estimate thereof, from an LSA licensee does not exceed a predefined threshold in order to protect the incumbent user. If the threshold is met or exceeded, the secondary users of the LSA band should cease operating in the LSA area 1 12 on the LSA band.

Using the 3 GPP Long-term Evolution (LTE) wireless communications standard as an example, without limiting the scope of the claimed subject matter, UE 1 14 can measure the received power from cell c assuming UE 114 is located at location x and the level of

PJ^'¾?) is larger than the sensitivity of the receiver circuitry of UE 1 14. In accordance with an LTE standard, this measurement is called the reference signal received power (RSRP). If UE 1 14 is equipped with a Global Navigation Satellite System (GNSS) or a Global Positioning System (GPS) receiver, GNSS or GPS data may be used to provide detailed location information in which each RSRP measurement report may additionally be tagged with detailed location information providing knowledge οΐ Ρ™ζχ) at the eNB such as cell 1 16.

For example, UE 1 14 may signal to the network 110 in the UE-EUTRA-Capability information element (IE) of the RRC protocol that it is equipped with a standalone GNSS receiver by setting the standaloneGNSS-Location field to supported. The network 100 may then instruct UE 1 14 to attempt to have detailed location information available using GNSS by configuring the ObtainLocationConfig field in the OtherConfig IE and setting the obtainLocation field to setup. In addition, the network 100 configures the UE 1 14 higher layers, using the RRC protocol, to include the location info in the measurement report by setting the includeLocationlnfo field in the ReportConfigEUTRA IE to true. The UE 114 higher layers, upon triggering of a reporting event, finally include the locationlnfo IE in the MeasResult IE such that each measurement result can be correlated with the UE position information.

Alternatively, if UE 114 is in RRC IDLE mode and does not report RSRP measurements as described above, a feature called minimization of drive tests (MDT) can be used which lets UE 114 log available measurements according to a logged measurement configuration. Prior to entering RRC IDLE mode, the network can send the LoggedMeasurementConfiguration message to instruct UE 114 to log measurements. According to this configuration, UE 114 adds logged measurement entries to the UE 114 variable VarLogMeasReport. In particular, the UE 114 variable VarLogMeasReport contains the logMeasInfoList field each entry of which, namely, the LogMeasInfo field, contains the measurement results together with the locationlnfo IE. When the UE 114 re-attaches to the network 100, it sets the logMeas Available field in the corresponding RRC message, for example one of RRCConnectionReconfigurationComplete, RRCConnectionReestablishmentComplete or RRCConnectionSetupComplete, to a value of true. The network 100 subsequently can poll the logMeasInfoList by sending the UEInformationRequest message to the UE with the logMeasReportReq field set to true. This triggers UE 114 to send the logMeasInfoList field in the logMeasReport field in the UEInformationResponse message to the network.

The aforementioned RRM procedures and RRC protocol were designed under the assumption that the quantity of interest is the received power f ^s(^). For example, in RRC CONNECTED mode where mobility is under complete control of the network 100 by means of handover procedures, knowledge of ^^s(» at the network side ensures that UE 114 is always or nearly always connected to the best or nearly the best cell, i.e., the cell with the strongest RSRP and/or with a favorable cell load. Accordingly, the reporting of fg*(x} is triggered by events based on this quantity as described in 3GPP Technical Standard (TS) 36.331 as follows:

Event Al : Serving becomes better than absolute threshold;

Event A2: Serving becomes worse than absolute threshold;

Event A3: Neighbor becomes amount of offset better than primary cell

(PCell)/primary secondary cell (pSCell);

Event A4: Neighbor becomes better than absolute threshold;

Event A5: PCell/pSCell becomes worse than absolute thresholdl AND

Neighbor becomes better than another absolute threshold2; Event A6: Neighbour becomes amount of offset better than SCell.

Similarly, the objective of MDT is to guarantee that at any location ^χ the RSRP is of sufficient strength in order to optimize coverage. For an LSA system, however, the quantity of interest is not the received signal strength ¾ itself but rather the aggregated interference:

which is the sum of received signal powers Pi ¾). Hence, new triggers and associated procedures for the reporting of RSRP measurements are described herein both for when UE 114 is in a connected mode (RRC CONNECTED) as shown in and described with respect to FIG. 2, below, and when UE 114 is in an idle mode (RRC IDLE) as shown in and described with respect to FIG. 3, below.

Referring now to FIG. 2, a diagram of radio resource management (RRM) procedures for licensed shared access (LSA) in a connected mode in accordance with one or more embodiments will be discussed. It should be noted that FIG. 2 illustrates one particular order and number of the operations of method 200, whereas in other embodiments method 200 may include more of fewer operations in various other orders, and the scope of the claimed subject matter is not limited in these respects. To determine if an aggregate interference threshold for LSA is exceeded, UE 114 may utilize enhancements to RSRP measurement reporting procedures when UE 114 is operating in a connected mode such as the RRC CONNECTED mode of an LTE standard.

In one embodiment, the UE 114 measures the RSRP Ff^£(x) according to existing RRM procedures. A new measurement reporting event is claimed which compares the sum of the RSRP ί£%ί of the ¾ strongest cells to a predefined threshold T. For purposes of discussion but without limiting the scope of the claimed subject matter, this event may be referred to as Ml :

Event Ml : Sum of the RSRP of the ¾ strongest cells becomes larger than

absolute threshold

The parameter A'_e can be defined by specification, configured via UE-specific RRC signaling, broadcasted in the system information, or left to implementation by UE 114. Similarly, the absolute threshold T can be defined by specification, configured via UE-specific RRC signaling, or broadcasted in the system information. In one example of the present embodiment, the two parameters and T are part of the ReportConfigEUTRA information element (IE) as illustrated below. It should be noted that the portions of information elements that have been amended or modified according to the subject matter of one or more embodiments as described herein is indicated with bold text.

In another embodiment, the event Ml can be configured by either of the two options below. Optionl comprises SUM-RSRP -Range for ml-Threshold-rxy.

Option2 may be enumerated by ml-Threshold-rxy. In this option, some predefined threshold is mapped to rl , r2, and r3 as shown in the example below by means of four values, using two bits for example. Other numbers of bits, however, are not precluded.

In yet another embodiment, the existing constant maxReportCells may be used rather than adding a new field ml-maxNumCells-rxy. In this case, the parameter ¾ may be fixed by the LTE specification. The associated radio resource management (RRM) procedures that may be performed by UE 114 are shown in FIG. 2. At block 210, UE 114 receives the measurement configuration from the network 100, for example according to the above embodiment. At block 212, UE 1 14 applies the received measurement configuration received at block 210. At block 214, UE 114 measures the reference signal received power (RSRP) according to existing radio resource management (RRM) procedures. At block 216, UE 114 evaluates the RSRP measurements 214 according to the measurement configuration received at block 210 and as applied at block 212. In particular, UE 114 evaluates the condition:

Event Ml : Sum of the RSRP of the N_c strongest cells becomes larger

than absolute threshold

At block 218, if a measurement reporting event Ml occurs, wherein event Ml has a value of true, UE 1 14 reports the measurements according to existing RRM procedures. For example, the existing RRM procedures may include transmitting detailed location information together with the measurement reports, although the scope of the claimed subject matter is not limited in this respect.

In another embodiment, the quantity is not the RSRP but rather the CSI-RSRP as defined in Section 5.1.20 of 3GPP Technical Specification (TS) 36.214. In yet another embodiment, UE 114 measures the aggregated interference Ιζχ) directly, for example by using existing reference signal strength indicator (RSSI) measurements. The associated RRM procedures implemented by UE 114 are as follows. UE 114 receives from the network the measurement configuration according to the above embodiment at block 210. UE 114 applies the received measurement configuration received at block 212. UE measures the RSSI according to existing RRM procedures as an alternative to the RSRP measurement of block 214. UE 114 evaluates the RSSI measurements according to the received measurement configuration as an alternative to the evaluation of an RSRP measurement of block 216. In this embodiment, UE 114 evaluates the condition: Event M2: RSSI becomes larger than absolute threshold

If a measurement reporting event M2 occurs, wherein event M2 has a value of true, UE 114 reports the measurements according to existing RRM procedures as an alternative to the event Ml of block 218. For example, the existing RRM procedures may include transmitting detailed location information together with the measurement reports, although the scope of the claimed subject matter is not limited in this respect. An example measurement configuration process using RSSI may be as shown below.

Similar to the previous example, in another embodiment, the parameter m2-Threshold-rxy in the configuration of the event M2 can be represented by enumeration, wherein some predefined threshold is mapped to rl , r2 and r3 as shown in the example below for two bits, however, any number of bits is also possible, and the scope of the claimed subject matter is not limited in this respect.

Referring now to FIG. 3, a diagram of radio resource management (RRM) procedures for licensed shared access (LSA) in an idle mode in accordance with one or more embodiments will be discussed. It should be noted that FIG. 3 illustrates one particular order and number of the operations of method 300, whereas in other embodiments method 300 may include more of fewer operations in various other orders, and the scope of the claimed subject matter is not limited in these respects. In the aforementioned minimization of drive tests (MDT) feature, the logged measurements are polled by the network 100. For LSA systems, whenever the aggregated interference exceeds a predefined threshold, the network 100 may have to take swift actions. For example, the radio access network (RAN) may cease operation on the given carrier frequency in the LSA spectrum in the LSA area 1 12. Alternatively, the RAN may turn off certain cells to lower the aggregated interference such that no harmful interference is caused to the incumbent.

In one embodiment, the network 100 configures UE 1 14 to perform logged measurements in RRC IDLE mode for LSA. In such an embodiment, UE 114 measures the RSRP according to existing RRM procedures, for example as done to perform cell selection or reselection. A new measurement reporting event is described herein which compares the sum of the RSRP

of the N_s strongest cells to a predefined threshold. For ease of discussion but without restricting the scope of the claimed subject matter, this event may be referred to as Ml :

Event Ml : Sum of the RSRP of the ¾ strongest cells becomes larger

than absolute threshold

The parameter N_e can be defined by specification, configured via UE-specific RRC signaling, broadcasted in the system information, or left to implementation by UE 114. Similarly, the absolute threshold T can be defined by specification, configured via UE-specific RRC signaling, or broadcasted in the system information. In one example of the present embodiment, the two parameters and T are part of the LoggedMeasurementConfiguration message as illustrated below.

The associated RRM procedures are as follows and shown in FIG. 3. At block 310, UE 1 14 receives the measurement configuration from the network 100 according to the above embodiment. At block 312, UE 114 applies the received measurement configuration from block 310. At block 314, UE 1 14 measures the RSRP according to existing RRM procedures. At block 316, UE 1 14 evaluates the RSRP measurements from block 314 according to the measurement configuration as received in block 310 and as applied in block 312. In particular, UE 114 evaluates the condition:

Event Ml : Sum of the RSRP of the A¾ strongest cells becomes larger

than absolute threshold

At block 318, if a measurement reporting event Ml occurs, wherein event Ml is true, UE

1 14 initiates a random access (RA) procedure by transmitting on the Physical Random Access Channel (PRACH). At block 320, UE 1 14 indicates mo-Signalling as an establishment cause in the RRCConnectionRequest message. At block 322, UE 1 14 sets the logMeasAvailable-rlO field to true in the RRCConnectionSetupComplete message.

In another embodiment, the quantity is not the RSRP but rather the CSI-RSRP. In yet another embodiment, UE 1 14 indicates at block 322 in the RRCConnectionSetupComplete message that the PRACH was triggered due to LSA event Ml . In one example of this embodiment, UE 114 thus sets a new field, for example logMeasAvailableLSA, to a vale of true as shown below.

~ ASN I STA RT

In yet another embodiment, UE 114 also includes the measurement results in the RRCConnectionSetupComplete message of block 322. In yet another embodiment, UE 114 measures the aggregated interference ιζ≠) directly, for example by using existing reference signal strength indicator (RSSI) measurements. The associated RRM procedures performed by the UE 114 are as follows. UE 114 receives from the network the measurement configuration according to the above embodiment per block 310. UE 114 then applies the received measurement configuration per block 312. UE 114 measures the RSSI as an alternative to the RSRP measurement of block 314 according to existing RRM procedures. As an alternative to the evaluation of an RSRP measurement of block 316 UE 114 evaluates the RSSI measurements according to the measurement configuration as received in block 310 and as applied in block 312. In particular, UE 114 evaluates the condition: Event M2: RSSI becomes larger than absolute threshold

If a measurement reporting event M2 occurs, wherein event M2 has a value of true, UE 1 14 initiates a random access (RA) procedure by transmitting on Physical Random Access Channel (PRACH) at block 318. Per block 320, in the RRCConnectionRequest message UE 1 14 indicates mo-Signalling as an establishment cause. Per block 322, in the RRCConnectionSetupComplete message, UE 1 14 sets the logMeasAvailableLSA field to true. An example measurement configuration may be implemented as follows.

In yet another embodiment, a new establishment cause may be utilized which allows UE 114 to signal to the network 100 in the RRCConnectionRequest message that the aggregated interference has exceeded the predefined or configured threshold. In one example of the embodiment, a reserved entry of the EstablishmentCause field of the RRCConnectionRequest message may be utilized as illustrated below.

In this example, the associated behavior of UE 114 is that UE 114 would not expect the network 100 to respond to the RRCConnectionRequest message by sending the RRCConnectionSetup message since UE 114 did not send the RRCConnectionRequest message to establish RRC_CON ECTION mode but rather to indicate to the network 100 the LSA event.

In a different example, behavior of UE 114 is slightly different. UE 114 would not expect the network 100 to respond to the RRCConnectionRequest message by sending the RRCConnectionSetup message. In addition, UE 114 initiates the cell selection or reselection procedure anticipating that the network 100 will turn off the cell on which UE 114 is currently camping due to the LSA event. In other words, upon transmission of the RRCConnectionRequest message with the EstablishmentCause field set to Isa-event, UE 114 begins to find another suitable cell on a different carrier assuming the shared carrier it is currently camping on is about to be turned off.

Consequently, in such examples, the behavior of network 100 is such that upon reception of an RRCConnectionRequest message with the EstablishmentCause field set to Isa-event, it does not send a RRCConnectionSetup message to the concerned UE 114.

Yet another embodiment is directed to Layer 1 reporting enhancements for LSA in the RRC IDLE mode. In such an embodiment, the establishment cause, that the aggregated interference has exceeded the predefined or configured threshold, is not signaled to the network 100 in the RRCConnectionRequest message. Instead, the network 100 broadcasts a dedicated PRACH preamble (sequence) in the system information. When either LSA event Ml or LSA event M2 is triggered, UE 114 initiates a random access procedure by transmitting the dedicated PRACH preamble (sequence). Upon reception of the dedicated preamble, the network 100 sends at least one downlink random access response (RAR) to stop the PRACH transmission of UE 114 in order to stop UE 114 from retransmitting the PRACH until a threshold is reached. In addition, UE 114, upon reception of the random access response (RAR) message, initiates the cell selection or reselection procedure anticipating that the network 100 will turn off the cell on which UE 114 is currently camping due to the LSA event. In other words, upon reception of the random access response (RAR) message received in response to its PRACH transmission using the dedicated preamble (sequence) for the LSA event, UE 114 begins to find another suitable cell on a different carrier assuming the shared carrier it is currently camping on is about to be turned off.

In further embodiments, additional RSRP measurement reporting enhancements for LSA may be provided. In addition to knowledge about the aggregated interference, it may also be beneficial for the network 100 to know whether UE 114 was located indoors or outdoors when the LSA event occurred, that is when the aggregated interference exceeded the predefined or configured threshold. Such knowledge may be beneficial since building structures may incur significant penetration losses, for example on the order of tens of decibels. In yet another embodiment, UE 114 indicates to the network 100 whether the location of UE 1 14 is indoors within the building structures or outdoors. UE 1 14 may obtain such information through implementation, for example from data bases that record for every access point, irrespective of the radio access technology, whether it is deployed indoors or outdoors. Similarly, UE 114 could infer from the availability of a GNSS or a GPS signal whether it is indoors or outdoors, although the scope of the claimed subject matter is not limited in this respect.

In one such example embodiment, UE 114 includes a flag into the Locationlnfo IE and transmits the flag together with the detailed location info, for example as shown below.

In another such example embodiment, UE 1 14 includes a flag into the Locationlnfo IE and transmits the flag together with the measurement results, for example in the MeasResults IE as shown below.

Referring now to FIG. 4, a block diagram of an information handling system capable of radio resource management measurement and radio resource control protocol for licensed shared access in accordance with one or more embodiments will be discussed.
