The MME 122 is similar in function to the control level of legacy server GPRS support nodes (SGSN). The MME 122 manages mobility aspects of access, such as gateway selection and tracking list management. The server GW 124 terminates the interface to the RAN 101 hints and routes data packets between the RAN 101 and the core network 120 , Furthermore, it may represent a local mobility anchor point for inter-eNB handovers and also provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful interception, loading and some enforcement of policies. The server GW 124 and the MME 122 can be implemented in a physical node or separate physical node. The PDN GW 126 terminates an SGi interface to the packet data network (PDN). The PDN GW 126 routes data packets between the EPC 120 and the external PDN and can be a key node for enforcing policies and loading collections of data. It can also provide an anchor point for non-LTE mobility mobility. The external PDN can be any type of IP network, as well as an IP Multimedia Subsystem (IMS) domain. The PDN GW 126 and the server GW 124 can be implemented in a physical node or separate physical node.

In cellular networks, LP cells are commonly used to extend coverage to indoor areas that do not respond well to outside signals, or to supplement network capacity in areas where very dense telephone usage occurs, such as in train stations. As used herein, the term low power (LP) eNB refers to any suitable relatively low power eNB for the implementation of a narrower cell (narrower than a macrocell), such as a femto cell, a picocell, or a microcell. Femtocellular eNBs are typically provided by a mobile network operator for residential or corporate customers. A femtocell is typically the size of a private gateway or smaller and usually connects to the user's broadband line. Once plugged in, the femtocell connects to the mobile operator's mobile network and provides additional coverage in a range of typically 30 to 50 meters for private femtocells. Thus, an LP-eNB may be a femtocell-eNB since it is represented by the PDN GW 126 is coupled. Similarly, a pico cell is a wireless communication system that typically covers a small area, such as in the building (offices, shopping malls, train stations, etc.), or more recently in airplanes. A pico cell eNB can generally connect through the X2 connection through its base station controller (BSC) function to another eNB such as a macro eNB. Thus, the LP eNB can be implemented with a picocell eNB because it is connected to a macro eNB via an X2 interface. Pico cell eNBs or other LP eNBs may implement some or all of the functions of a macro eNB. In some cases, this may be referred to as an access point base station or enterprise femtocell. In some embodiments, different types of gNBs may be used 105 may be used, including but not limited to one or more of the eNB types described above.

In some embodiments, a downlink resource network may be for downlink transmissions from an eNB 104 to a UE 102 used while the uplink transmission from the UE 102 to the eNB 104 can use similar techniques. In some embodiments, a downlink resource network for downlink Transfers from a gNB 105 to a UE 102 used while the uplink transmission from the UE 102 to the gNB 105 can use similar techniques. The grid may be a time-frequency grid, referred to as the resource lattice or time frequency resource lattice, which represents the physical resource in the downlink in each slot. Such time frequency level representation is a common method for OFDM systems, making it intuitive for radio resource allocation. Each column and row of the resource grid corresponds to an OFDM symbol or an OFDM subcarrier. The duration of the resource grid in the time domain corresponds to a slot in a radio frame. The smallest time-frequency unit in a resource grid is referred to as resource element (RE). There are several different physical downlink channels that are transmitted using such resource blocks. Of particular relevance to this disclosure, two of these downlink physical channels are the shared downlink physical channel and the downlink physical control channel.

As used herein, the term "circuitry" may refer to an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, special or group), and / or memory (shared, special or group), Be part of or contain one or more software or software
Firmware programs, a combination logic circuit, and / or other suitable hardware components that provide the described function.

In some embodiments, circuitry may include logic that is at least partially operable in hardware. Embodiments described herein may be implemented in a system using any suitably configured hardware and / or software.

For a subcarrier spacing of 2 ⁿ * 15kHz, the grating may be defined as a subset / overset of the grid for a subcarrier spacing (such as a reference subcarrier spacing) of 15kHz in an interleaved manner in the frequency domain.

In some embodiments, a power can be normalized over a transmission bandwidth. Because of this, for a UE 102 a power measured per subcarrier is measured for different subcarrier spacings. However, in some cases (including but not limited to cases where LTE is supported), an RSRP may be a linear average of the power contributions (such as in watts or other unit) of the subcarriers carrying cell specific reference signals within the considered measurement frequency bandwidth. Since the power per RE may depend on the subcarrier spacing, the measured RSRP may vary. For example, if the subcarrier is 30KHz, in some cases the RSRP may be twice the RSRP for a subcarrier spacing of 15kHz in some cases.

In some embodiments, an intermediate carrier may be a resource element (RE), although the scope of the embodiments is not limited in this regard. It should be noted that references herein to subcarriers or REs are not limitative. In some embodiments, any suitable entity (RE, subcarrier, and / or other) may be used in the operations, techniques, concepts, and / or methods described herein.

In some cases, a reported RSRP per RE may depend on a subcarrier spacing. Accordingly, the reported RSRP per RE can differ among cells in which the inter-carrier distances are varied. For example, in New Radio (NR) systems, the reported RSRP may not be sufficient to justify the true signal strength among the load cells / carriers where the subcarrier spacing varies.

In the example in 10 can in the scenario 1000 an RSRP (as indicated by 1015) for subcarriers 1010 be determined at a distance of f0. In the scenario 1050 may use an RSRP (as indicated by 1065) for subcarriers 1060 be determined at a distance of 2 * f0.

In some embodiments, an RSRP attached to an eNB 104 is reported based on a reference subcarrier distance be normalized. In some embodiments, the RSRP may be a linear average over the power contributions (such as in watts or other unit) of the subcarriers (and / or REs) carrying cell specific reference signals within the considered measurement frequency bandwidth. Power measurements of the subcarriers (and / or REs) may be scaled by a ratio between the subcarrier spacing used by the UE for the power measurements and the reference subcarrier spacing. As an example and not by way of limitation, a reference point for the RSRP may be an antenna port of the UE 102 his. In some cases, if the recipient diversity through the UE 102 the reported value should be constrained to be no less than the corresponding RSRP of one of the individual diversity branches.

In some embodiments, techniques described herein for RSRP measurement and / or reporting may apply to one or more radio resource control (RRC) states, including but not limited to RRC_IDLE intra frequency, RRC_IDLE inter frequency, RRC_CONNECTED intra frequency, RRC_CONNECTED inter frequency, and / or similar states ,

In some embodiments, the UE 102 send the scaled RSRP to the network (such as the eNB) 104 ). The eNB 104 may trigger events based on the scaled RSRP (such as handover, handoff, and / or one or more others). In some cases, using the scaled RSRP can reduce the potential impact of using disparate intercarrier spacing.

In some embodiments without reference numerology, an old RSRP (as used in LTE and / or other protocols) may be used. Accordingly, the UE 102 the RSRP per RE to the eNB 104 report and also the intercarrier distance of the measured cells / carriers to the eNB 104 Report. As an example and not by way of limitation, a non-limiting ReportConfigNR information element (IE), another IE, and / or another element may display a field (such as "scSpacing" and / or one or more others) indicating the subcarrier spacing used for the RSRP Measurement is used included. In some cases, the same IE and / or element may also include the RSRP, but the scope of the embodiments is not limited in this regard.

In some embodiments, the network and / or the eNB 104 receive the RSRP and the subcarrier spacing and can read the RSRP from the UE 102 convert, normalize and / or scale based on the subcarrier spacing. For example, a ratio between the reported subcarrier spacing and the reference subcarrier spacing may be used.

In some embodiments, a method of NR measurement may include determining a metric based on a reference signal power measurement that has been normalized by an intercarrier spacing. For example, an RSRP can be used. The measurement can be used for mobility management and / or another application. The numerology of the measuring carrier may differ from that of a separating cell. In some embodiments, the RSRP may be controlled by the UE 102 by a power scaled by a ratio between the subcarrier spacing (used for the measurement) and a reference subcarrier spacing. In some embodiments, the eNB 104 and / or the network compare the reported RSRPs for multiple neighboring cells / carriers to determine if one or more mobility events are to be triggered.

In some embodiments, the RSRP may be controlled by the UE 102 be determined without scaling based on performance (such as power of the subcarriers and / or REs carrying reference signals). In some embodiments, the intercarrier distance of the measured cells / carriers to the eNB 104 and / or the network. In some embodiments, the eNB 104 and / or the network reevaluate the reported RSRP with the known inter-carrier distance. In some embodiments, the eNB 104 and / or the network compare the reevaluated RSRP for the multiple neighbor cells / bearers, and possibly trigger corresponding mobility events.

In the example scenario 1100 can be an eNB 104 a surgery 1105 which may include configuring measurements of adjacent cells. For example, the eNB 104 determine one or more neighbor cells for the measurements (such as RSRP and / or one or more others) by the UE 102 to be determined. In some embodiments, the UE 102 in an RRC-connected mode and / or a similar mode, although the scope of the embodiments is not limited in this respect. The eNB 104 can send a message or other item, including but not limited to a MeasObjectNR, to the UE 102 can provide information for measurements of neighboring cells. As indicated by 1115, the UE 102 perform one or more operations, including, but not limited to: detection one or more signals (such as a PSS, SSS and / or others), RRM measurement (s), inter-carrier distance detection and / or one or more others. As indicated by 1120, the UE 102 a measurement report to the eNB 104 transfer. The measurement report may contain information such as RSRP, inter-carrier distances and / or others.

In some embodiments, a New Radio (NR) protocol may support flexible channel bandwidth. In comparison with LTE, in some cases a much wider bandwidth of an NR carrier can be used. For example, in some cases, a bandwidth greater than or equal to 80 MHz may be used. In some embodiments, a UE 102 work with a maximum supported bandwidth that may be less than a channel bandwidth of a carrier of a server cell.

In 12 For example, in Example 1200, different UE bandwidths are different UEs 102 supported as indicated by 1222, 1224, 1226. The example bandwidths 20 MHz and 40 MHz are not restrictive. The system bandwidth 1205 is greater than the UE bandwidths 1222 . 1224 . 1226 in this example. Furthermore, a reference signal 1210 (PSS, SSS and / or others) in this case in (or near) a middle of the system bandwidth 1205 transmitted. In some cases, the UE 102 support a bandwidth that overlaps the frequency resources used for the reference signal. However, in Example 1250, the frequency resources covered by the UEs overlap 102 used (as by the UE bandwidths 1272 . 1274 . 1276 displayed), not the frequency resources used to transmit the reference signal 1260 be used.

In some embodiments, reference signals (including but not limited to PSS, SSS, BCH, and / or others) may be duplicated in the frequency domain. In some embodiments, initial access signals (including but not limited to PSS, SSS, BCH and / or others) may be duplicated in the frequency domain. The UE 102 may detect a signal (PSS, SSS, BCH and / or others) transmitted within the UE bandwidth. The UE 102 may determine one or more measurements for one or more neighbor cells in the same carrier band. In some cases, the UE 102 determine the measurements without measuring gap. In the example 1300 in 13 become the signals 1312 . 1314 and 1316 (by an eNB 104 ) in the bandwidths 1322 . 1324 . 1326 transmitted.

In some embodiments, jumps may be used. For example, jumps in the time domain, frequency domain and / or both can be used. As an example and not by way of limitation, a signal (PSS, SSS, BCH and / or something else) may be used in the various sections over a system bandwidth. The signals may be transmitted at different locations during each of the multiple time periods. In example 1350 in 13 At time t1 (indicated by 1360), the signal becomes 1362 within the UE bandwidth 1392 transmitted. At time t2 (indicated by 1370) the signal becomes 1372 within the UE bandwidth 1394 transmitted. At time t3 (indicated by 1380), the signal becomes 1382 within the UE bandwidth 1396 transmitted. Embodiments are not limited to the pattern of Example 1350. Embodiments are also not limited to the number of elements (such as channels, UE bandwidths, and / or one or more others) shown in Example 1350.

In some embodiments, a reference signal may be communicated in different frequency resources (REs, RBs and / or others). In some embodiments, a location of a reference signal in the frequency domain may vary randomly. In some embodiments, a location of a reference signal in the frequency domain may vary based on a hopping pattern (which in some cases may be known and / or predetermined).
