CELL SPECIFIC GROUP MEASUREMENT GAP FOR CARRIER AGGREGATION
REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No.
62/145,31 8 filed April 9, 201 5, entitled "CELL SPEC MG", the contents of which are herein incorporated by reference in their entirety.
FIELD
[0002] The present disclosure relates to measurement gaps, and more specifically, cell specific group measurement gaps for carrier aggregation.
BACKGROUND
[0003] Wireless mobile communication technology uses various standards and protocols to transmit data between a node (e.g., a transmission station) and a wireless device (e.g., a mobile device), or a user equipment (UE). Some wireless devices communicate using orthogonal frequency-division multiple access (OFDMA) in a downlink (DL) transmission and single carrier frequency division multiple access (SC- FDMA) in an uplink (UL) transmission. Standards and protocols that use orthogonal frequency-division multiplexing (OFDM) for signal transmission include the third generation partnership project (3GPP) long term evolution (LTE), the Institute of Electrical and Electronics Engineers (IEEE) 802.16 standard (e.g., 802.16e, 802.16m), which is commonly known to industry groups as WiMAX (Worldwide interoperability for Microwave Access), and the IEEE 802.1 1 standard, which is commonly known to industry groups as WiFi.
[0004] In 3GPP radio access network (RAN) LTE systems, the node can be a combination of Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node Bs (also commonly denoted as evolved Node Bs, enhanced Node Bs, eNodeBs, or eNBs) and Radio Network Controllers (RNCs), which communicates with the UE. The downlink (DL) transmission can be a communication from an access point / node or base station (e.g., a macro cell device, an eNodeB, an eNB, or other similar network device) to the UE, and the uplink (UL) transmission can be a communication from the wireless device to the node. In LTE, data can be transmitted from the eNodeB to the UE via a physical downlink shared channel (PDSCH). A physical uplink control channel (PUCCH) can be used to acknowledge that data was received. Downlink and uplink channels can use time-division duplexing (TDD) or frequency-division duplexing (FDD).
[0005] Future network deployments ensure that the number of frequencies is going to increase as a result of higher demand and newer technology evolving in wireless communication. The number of cells and frequency demand will increase. Macro cell network devices, small cell network devices or the other such network devices having a smaller coverage zone or lower power capability than a macro cell device (e.g., small eNBs, micro-eNBs, pico-eNBs, femto-eNBs, home eNBs (HeNBs)) can also be introduced with dual connectivity features as specified in 3GPP Release 12. The user equipment (UE) (e.g., a network device, a mobile device, a wireless device or the like) can thus be capable of connecting two or more cells simultaneously.
[0006] In order to facilitate smooth network transitions (e.g., cell handovers, redirection, reselection, or the like)) with high a quality of experience (QoE), the UE has to have the capability to measure surrounding cells and provide related data to the network. In network deployment situations there may be many frequencies, some of the frequency carriers can be micro cells that have been deployed back to back in dense network deployments. However, the UE may not be able to switch to those cells as a result of a large load within the macro cell, for example. As a result of a large network deployment density, the UE may not be able to access these small cells depending on the location of the UE. If the UE misses chances of measuring small cell frequency carriers, it might not have a backup network available. Additionally, if it misses measurements to the macro layers, the UE may not be able to handover fast enough and a call could drop. As such, the network, for example, might designate the macro cell layer or particular network devices (e.g., one or more macro / small cell network devices) to a normal performance group and small cell layer or other particular network devices (e.g., one or more macro / small cell network devices) to a reduced
performance group so that the UE would perform more measurements in the normal performance group and fewer measurements in the reduced performance group. The reason these two groups are introduced is because 3GPP release 12 increased the number of carriers that the UE measures. Because the UE has to measure more carriers, this introduces more delays to measure one particular carrier. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The present disclosure will now be described with reference to the attached drawing figures, wherein like reference numerals are used to refer to like elements throughout, and wherein the illustrated structures and devices are not necessarily drawn to scale. As utilized herein, terms "component," "system," "interface," and the like are intended to refer to a computer-related entity, hardware, software (e.g., in execution), and/or firmware. For example, a component can be a processor, a process running on a processor, a controller, a circuit or a circuit element, an object, an executable, a program, a storage device, a computer, a tablet PC and/or a mobile phone with a processing device. By way of illustration, an application running on a server and the server can also be a component. One or more components can reside within a process, and a component can be localized on one computer and/or distributed between two or more computers. A set of elements or a set of other components can be described herein, in which the term "set" can be interpreted as "one or more."
[0025] Further, these components can execute from various computer readable storage media having various data structures stored thereon such as with a module, for example. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network, such as, the Internet, a local area network, a wide area network, or similar network with other systems via the signal).
[0026] As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, in which the electric or electronic circuitry can be operated by a software application or a firmware application executed by one or more processors. The one or more processors can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components or elements without mechanical parts; the electronic components can include one or more processors therein to execute software and/or firmware that confer(s), at least in part, the functionality of the electronic components.
[0027] Use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. In addition, the articles "a" and "an" as used in this application and the appended claims should generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Furthermore, to the extent that the terms "including", "includes", "having", "has", "with", or variants thereof are used in either the detailed description and the claims, such terms are intended to be inclusive in a manner similar to the term
"comprising".
[0028] In consideration of the above described deficiencies, network devices (e.g., macro cells, Access Points (APs), Access Controllers (ACs), eNBs, small cells, UEs, etc.) described herein can enable one or more specific measurement gap patterns and related solutions to support LTE carrier aggregation (CA) of up to 32 carrier components (CCs) for DL and UL. For CA processes, two measurement performance groups alone may not be enough for the LTE CA to support up to 32 CCs or more. Various measurement gap patterns are proposed in this disclosure to more efficiently measure carriers at the measurement gaps. A measurement gap pattern can be referred to, for example as the pattern of measurement gaps that the UE can facilitate frequency carrier measurements on within a time period or duration. The UE, for example, can operate during a measurement gap to switch from a serving band it is connected on to a different band in order to perform a measurement of the carrier. The term serving band as used herein means the UE can be connected to that band as a serving band and can receive downlink data), in this case no measurement is necessarily required in that band because the UE is already operating in that band. [0029] For example, in one measurement gap pattern a first receive circuitry component (e.g., an RF chain or pipeline having one or more antenna ports, antennas, filters, signal processors or other circuitry for processing received signals at one or more frequencies) can be configured to operate on a first band during a first measurement gap to facilitate measurement of the first band. In addition, a measurement can be performed on a second band at a second measurement gap. The first receive circuitry component can further operate on a first serving band to downlink data at other time periods or intervals other than during the first and second measurement gaps or outside of the measurement gap pattern, for example as distinguished from a different serving band the the additional / second receive circuitry would operate on.
[0030] A second or additional receive circuitry component can also be configured to operate on a third band at the first measurement gap and a fourth band at the second measurement gap to facilitate measurements of the third band and the fourth band during the respective measurement gaps. The second receive circuitry component can also further operate on a second serving band to downlink data at the other time periods. The first serving band, the second serving band, the first band, the second band, the third band, and the fourth band can be different carrier frequencies from one another.
[0031] In an embodiment, the first receive circuitry component and the second receive circuitry component are further configured to receive downlink data in a different measurement gap that occurs between the first measurement gap and the second measurement gap. Therefore, the sequence for measuring during the measurement gaps would alternate between measuring respective bands that the first and second receive circuitry components cover, and downlinking data on their respective serving band. As such, while making measurements during the measurement gaps, downlink data can be inhibited. An advantage here is that the problem of having no downlink data or very little can be improved by increasing downlink data efficiency.
[0032] In another embodiment, The first receive circuitry component can facilitate a measurement of a first band at a first measurement gap, and at a second measurement gap measure a second band while concurrently downlinking data on a first serving band. At a third measurement gap the first receive circuitry component could perform no measurements or downlink data, and at a fourth downlink data on the serving frequency. Concurrently, simultaneously or at about the same time, the second receive circuitry component can downlink data on a second serving band that is different from the first serving band at the first measurement gap, perform no measurements or downlink data at the second measurement gap, measure a third band at a third measurement gap while concurrently downlinking data on the second serving band, and measure a fourth band at a fourth measurement gap. Additional aspects and details of the disclosure are further described below with reference to figures.
[0033] FIG. 1 illustrates an example non-limiting wireless communications environment 100 that can facilitate or enable one or more measurement gap
configurations via communications between the base station network device (e.g., eNB) and UEs for LTE CA to support an increased number of frequency carriers or carrier components. The wireless communications environment 100 can include a multitude of wireless communications networks, each having a respective coverage area. The coverage area of some of the wireless communications networks can overlap such that one or more mobile devices might be served by any one of the network devices whose coverage areas overlap.
[0034] Wireless communications environment 100 includes one or more cellular broadcast servers or macro cell NDs 102, 104 (e.g., base stations, eNBs, APs or the like) and one or more small cell NDs or APs (e.g., small eNBs, micro-eNBs, pico-eNBs, femto-eNBs, home eNBs (HeNBs), or Wi-Fi nodes) 106, 108 deployed within the wireless communications environment 100 and servicing one or more UE devices 1 10, 1 1 2, 1 14, 1 16, 1 18. Each wireless communications network (e.g., cellular broadcast servers 1 02, 104 and small cell network devices 106, 1 08) comprises one or more network devices (e.g., a set of network devices (NDs)) that operate in conjunction in order to process network traffic for the one or more UE devices 1 10, 1 12, 1 14, 1 16, or 1 1 8. For example, macro cell NDs 102, 104 can comprise a set of network devices that are cellular enabled network devices. In another example, the small cell network devices 106, 1 08 can include a set of network devices that operate with a smaller coverage zone than the macro cell network devices 102 and 102, for example.
[0035] Although network devices (NDs) 106 and 108 are described as small cell network devices, they can also be Wi-Fi enabled devices or wireless local area network (WLAN) devices, as well as macro cell network devices, small cell network devices, or some other type of ND operable as a base station or eNB, for example. Alternatively one or more of the macro cell NDs 102 and 1 04 could be small cell network devices or other NDs of a different radio access technology (RAT) that operate with different frequency carriers, for example. [0036] As illustrated, each of the one or more Wi-Fi access points 106, 1 08 can have a corresponding service area 120, 122. Additionally, each of the one or more cellular broadcast servers or macro cell NDs 102, 104 can have a corresponding service area 124, 126. However, it should be understood that the wireless communications environment 100 is not limited to this implementation. For example, any number of APs or NDs with respective service areas can be deployed within the wireless
communications environment 100. Further, any number of cellular broadcast servers and respective service areas can be deployed within the wireless communications environment 100 as well.
[0037] Although only five UE devices 1 10, 1 12, 1 14, 1 1 6, 1 18 are illustrated, any number of UE devices can be deployed within the wireless communications
environment 100 as well. A UE device can contain some or all of the functionality of a system, subscriber unit, subscriber station, mobile station, mobile, wireless terminal, device, mobile device, remote station, remote terminal, access terminal, user terminal, terminal, wireless communication device, wireless communication apparatus, user agent, user device, or other ND, for example. A mobile device can be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a smart phone, a feature phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a laptop, a handheld communication device, a handheld computing device, a netbook, a tablet, a satellite radio, a data card, a wireless modem card and/or another processing device for communicating over a wireless system. In addition, the UE devices 1 10, 1 12, 1 14, 1 1 6, 1 18 can include functionality as more fully described herein and can also be configured as dual connected devices, in which one or more of the UE devices 1 10, 1 12, 1 14, 1 1 6, 1 18 can be connected to more than one eNB or ND of different RATs (e.g., LTE and WLAN, or other combination).
[0038] In one aspect, cellular broadcast servers or macro cell NDs 102, 104 and small cell NDs 106, 108 can monitor their surrounding radio conditions (e.g., by employing respective measurement components). For example, each of the macro cell NDs 102, 1 04 and small cell NDs 106, 108 can determine network traffic load on its respective network by performing a network diagnostic procedure. As an example, during a network listen procedure, macro cell NDs 1 02, 104, small cell NDs 106, 1 08 or UE devices 1 10, 1 12, 1 14, 1 16, 1 1 8 can scan their radio environment to determine network performance statistics or network parameters (e.g., frequency, SNR, signal quality, QoS, QoE, load, congestion, signal rate, etc.). Various parameters associated with macro cell NDs 102, 104 and small cell NDs 106, 108 can be detected during the network diagnostic procedure or measurements by the UE devices, such as, but not limited to, frequency bands, scrambling codes, common channel pilot power, bandwidth across respective networks, universal mobile telecommunications system terrestrial radio access receive signal strength indicator, as well as frequency carrier priorities for particular cell groups (e.g., a normal group or a reduced group) and so on.
[0039] In an example scenario, UE devices 1 10, 1 12, 1 14, 1 16, 1 18 can be serviced by networks through one of the macro cell NDs 102, 104, or small cell NDs 106, 108. As a user equipment device is moved within the wireless communications environment 100, the respective user equipment device might be moved in and out of the coverage area of the associated serving network. For example, as a user is sending/receiving communications through their respective UE device, the user might be walking, riding in a car, riding on a train, moving around a densely populated urban area (e.g., a large city), wherein the movement might cause the mobile device to be moved between various wireless communication networks. In such cases, the UE it is beneficial to route the network traffic (e.g., handoff) from a serving ND to a target ND in order to continue the communication (e.g., avoid dropped calls) or facilitating offloading for load distribution or other efficiency purposes. However, with an increased number of NDs and frequency carriers to measure, UE devices 1 10, 1 12, 1 14, 1 16, 1 18 can have a problem being able to measure each carrier within allotted time measurement gaps. Because the UE devices 1 10, 1 1 2, 1 14, 1 1 6, 1 18 have to measure an increase number if carriers (e.g., 32 or greater), these measurement gaps can introduce more delays.
[0040] In one example, if two frequency carriers (e.g., carriers components for LTE CA) of different frequencies exist on the network environment 1 00, where 40
milliseconds (ms) is the measurement gap. Because there are two carriers, the UE devices 1 10, 1 12, 1 14, 1 1 6, 1 18 would operate on one carrier, which is the serving frequency, and thus would only have to measure one additional carrier. As such, every 40ms the UE (e.g., UE 1 10) would switch to the other carrier to perform measurements thereon. This means every 40ms the UE 1 10 would measure once as a measurement gap reception period (MGRP). At each measurement sample, measurements could comprise any network measurement of network conditions related to the frequency band, network device operating (communicating) the frequency band, or channel conditions, such as a signal strength, a channel quality, a load condition of the ND, or other measurement such as a reference signal received power (RSRP), a reference signal received quality (RSRQ), channel state information (CSI), one or more channel quality indicators (CQIs) or the like.
[0041] However, if two additional carriers are present on the network or within communication range (communicatively coupled to the UE device 1 10) for the UE devicel 1 0 to measure, then three carriers exits on the network with the serving frequency carrier that the UE device 1 10 can downlinks data and communicate on. In a first measurement gap of a sequence of gaps, the UE device 1 1 0 can measure a second frequency (the serving frequency being the first), for example, and in a second or subsequent measurement gap the UE device 1 10 could measure a third frequency of a different carriers. This means that at every 80ms the UE device could only measure once. This is a longer delay than just having to measure one frequency carrier, in which the total delay is proportional to the number of carriers that the UE device 1 1 0 has to measure. Thus, thirty-two or more carriers would mean a gap delay of approximately 32 * 40ms (measurement gap repetition/reception period) to get one sample of a particular frequency or frequencies (inter-frequency or intra-frequency) of one or more different NDs. This longer delay can create problems for the UEs, which may not be able to measure the frequencies within a sufficient or efficient time frame. This longer delay can also cause further problems with network handovers and determining what cell or cell ND is optimal in an adequate time based on the conditions of the UE device 1 1 0, for example.
[0042] In one aspect, the network objective therefore is to enhance the time measurement gap for the carriers belonging to a normal performance group, which can receive more measurements than a reduced performance group. The network can allocated which carriers or NDs are a part of which group. For example, the normal performance group could have the macro cell NDs 202, and 204, while the reduced performance group could have small cell NDs 106, 108; however, any mix of NDs and associated frequency carriers can be designated by the network or ND device (e.g., macro cell ND 1 02) or the like. The NDs or UEs of the network can be enhanced in various embodiments to enable carrier aggregation of up to 32 component carriers for both DL and UL, and further enable about frequency five carriers or more, for example, to be supported at one time. Thus, in addition or alternatively for CA, two measurement performance groups for CA various specific cell measurement gap patterns for CA to support up to 32 CC in CA are disclosed. [0043] Referring to FIG. 2, illustrated are examples of identifiers (IDs) for the number of measurements for a carrier that instruct a UE from the eNB. In radio resource (RRM) measurement in LTE, the frequency carrier or band that the UE performs a
measurement can be configured by a measurement object (e.g., measObject). The maximum number of measurement objective IDs maxObjectld 202, for example can be defined in 3GPP specifications. In principle, a single measurement object is configured per radio frequency (RF) carrier. Considering up to thirty-two CCs projected for Rel-13 CA, theoretically the number of measurement object IDs to meet objectives can be increased to an even larger value (e.g. 64). On the other hand, the maximum value expressed by the data field 202 could be still sufficient. There might be some cases when the UE is configured with up to 32 CCs, eNB could derive the necessary information for the purpose of CCs management from a measurement report on one CC in the same frequency band. Such a solution, for example, could be applied at least to the aggregation of carrier B and C when carrier B and C are in the same frequency band, for example. Correspondingly, the required measurement object IDs can be reduced and current value could be sufficient.
[0044] The ID 202 includes thirty-two CCs as a way to designate a measurement of object ID. When the network increases the measurement object to accommodate more than 32 CCs (e.g., as in the data ID 204 maxObject ID designating the max integer 64), the network also can configure more measurement objects to link to the measurement configuration (MeasGapConfig), in which 32 may not be enough. Thus the eNB can provide for a suggested increase to about 64 CCs or other amount, which is just an example, in order to accommodate the increase in number of carrier frequencies. The E-UTRAN, for example, can apply processors with the data IDs 202 or 204, for example, or some other increase, to ensure then that whenever the UE receives a measConfig, it includes a measObject for each serving frequency with the maxObjectID, for example.
[0045] Referring to FIG. 3, illustrated is an example of a measurement gap pattern 300 in accordance with various embodiments and in reference to FIG. 1 . The measurement gap pattern 300 can operate, for example, with a measurement gap repetition/reception period of either as a 40ms or a 80ms. The measurement gap pattern 300 , for example, can be implemented with a single server (serving) band for operation with a single radio frequency (RF) chain (not shown) with a constant gap duration of each gap at about 6ms, which can be provided by the eNB (e.g., ND 102) to the UE device (e.g., 1 14). An RF chain (e.g., a transmit circuitry component/receive circuitry component), for example, can comprise one or more processing components (e.g., filters, digital signal processors, amplifiers or other components for processing data signals) that can cover various ranges the RF spectrum. The UE 1 14 does not have to utilize all RF chains to do inter-frequency measurement for a certain frequency carrier, such as with measurement gap pattern 300.
[0046] As state above, the duration of each gap can be about 6ms, which is applied or configured by the eNB (e.g., ND 1 02) to the UE device 1 14 of FIG. 1 , for example. During this 6ms gap there is no data transmission. However, the UE device 1 14 can also have CA capability, which means the UE device 1 14 can operate with more than one RF chain at a time. Thus, with more than one RF chain, it is possible that the UE device 1 14 can increase the throughput gain by using some of the RF for measurement and simultaneously having data. As such, radio resource management (RRM) measurements without a gap can bring up to 15% of throughput gain (e.g., 40ms MGRP) as such it is a desire to improve UE device performance especially in case of CA with a large number of CCs. To achieve this benefit, measurement gap is better applied to only relevant serving cells (i.e., to the serving cells operating on the RF circuit measuring the concerned frequency).
[0047] The measurement gap pattern 300 (i.e., either 40ms MGRP or 80ms MGRP) can be configured by the network to the UE. The network takes into account that the UE performs measurements one band at a time to satisfy the measurement requirement and that all bands during the measurement gap will not have downlink transmission. For example, the network could have five frequencies available such that the serving band is band A 302, which can be the serving frequency that the UE facilitates connected operations on. The other bands, for example, can include Band X 304, Band Y 306, Band Z 308 and Band L 310. The black gaps indicate where no measurement can be performed, the darker shaded gaps (e.g., gaps 312) indicate where
measurements of the bands can be performed and the lighter shaded gaps (e.g., 314) indicate where no data transmission can occur.
[0048] Based on the measurement gap pattern 300, the UE device 1 14 could perform measurement on Band X 304 in the first 40 millisecond gap 31 6, while there is no data transmission on serving Band A 302. Each band, for example, can represent a frequency band or range for DL or UL. Then in the next 40 millisecond measurement gap 318, the UE device 1 14 can measure Band Y 306. Then in the third measurement gap 320, the UE device 1 14 can measure band Z 308 and subsequently measure Band L 310, in the fourth measurement gap 322. Then the UE device 1 14 can cycle again to measure Band X 304 again, in which the sequence of measurement gaps can continuously repeat.
[0049] Referring to FIG. 4, illustrates an example of a CA scenario 400 together with an example UE 1 14, where for an RF chainl 402, the UE device 1 14, for example, can cover the frequency Band X 304 and Band Y 306. Each RF chainl 402 and RF chain2 404 can comprise one or more components for a signal processing chain, for example, that can include a filter as well as hardware to increment the filter as well as further process RF signals for data. Because the frequency can be high, not all of the RF chains can cover all of the frequency bands at once. For example, RF chainl 402 can only cover Band X 304 (e.g., any frequency range either for DL or UL as specified by 3GPP) and Band Y 306. Additionally, RF chain2 404 can only cover Band Z 308 and Band L 310, in which each RF chainl 402 and RF chain2 404 can cover certain frequency bands or bandwidths of a frequency spectrum.
[0050] Referring now to FIG. 5, illustrated is an example of another measurement gap pattern 500 of a measurement gap configuration information element for release 13 or beyond to reduce measurement delay via one or more network devices on the network. As in the measurement gap pattern 300 of FIG. 3, a measurement delay in the measurement gap pattern 500 occurs in a pattern of four measurements to obtain a measurement sample of each band (e.g., Band X, Y, Z, and L). As such in every 160ms the UE device 1 14 can obtain one sample of each Band, which is considered the measurement delay. In the measurement gap pattern 300, if the UE device 1 14 can measure Band X 304 and Y 306, using one serving frequency, for example, and Band Z and L while using a second serving frequency.
[0051] In the first measurement gap 502 the UE device 1 14 can measure Band X 304 using RF chainl 402 and Band Z 308 using RF chain2 404, and measure simultaneously. Likewise, in the second measurement gap 504, the UE device 1 14 could measure Band Y with RF chainl 402, and measure Band L 310 with RF chain2 404. The pattern then repeats itself for measurement gaps 508 and 510. Now in each measurement gap the UE device 1 14 could measure two Bands instead of one Band, and the measurement delay has thus been cut in half because the UE device 1 14 can utilizing both RF chains simultaneously. Instead of needing four measurement gaps to obtain measurement samples of all the bands, only two could be used in this scenario for example.
[0052] However, the network could assume the UE device 1 14 only has one RF chain instead of two, while the measurement requirements are also based on only one RF chain, which would not take advantage of the network capabilities unless adequate communication is ensured between network devices (e.g., the UE and eNB). Therefore, gap configurations can be further added to the 3GPP standards (TS 36.331 ) for further facilitating communication based on a CA specific measurement pattern measurement. Instead of only utilizing the existing zero and one, which is 40ms and 80ms, an additional specification could be added as illustrated in FIG. 6 as CA-gapO 602, which is part of a measurement gap configuration (MeasGapConfig) on an information element (IE) 600.
[0053] FIG. 6 illustrates an example of a measurement gap configuration or
MeasGapConfig that enables the measurement gap patterns to be communicated and implemented between NDs (e.g., eNB(s) and UE(s)) such as illustrated in FIGs. 5 and 8, for example. The data slot or item CA-gapO 602 indicates the gap repetition period 604, which could be 40ms and 80ms, as well as have one or more spares for optional or future extension. Additionally, the CA-gapO 602 data item of the MeasGapConfig IE can further comprise a measurement gap offset 606, which indicates when the gap has started for further measurement. The CA-gapO 602 further indicates a band
measurement list (bandMeasurementList) 608, which includes which measurement Band the UE should measure using that measurement gap. For example, a reduced performance group or a normal performance group could divided and be specified as well by indicating certain bands needing measurement, either more frequently or at all with the band measurement list 608.
[0054] The gap offset (gapOffset) 602 describes that the gpO value can correspond to a gap offset of a Gap Pattern Id "0" with measurement gap repetition/reception period (MGRP) = 40ms for example. The gap offset of gp1 can correspond to the gap offset of Gap pattern "1 " with a MGRP = 80ms. These gap offset pattern IDs can be used to specify the measurement gap pattern to be applied as defined in the specification of release 1 3 or beyond, for example, which provide information for a selection to be determined (e.g., via the UE or the eNB), for example, among the IDs. For example, ca-gapO 602 comprises the gapOffset-r13 606 as the gapOffset value based on the gap pattern repetition period (or MGRP) (gapRepetitionPeriod) selected, or the measurement gap pattern repetition period as defined in 3GPP specification TS 36.133, for example. Finally, the bandMeasurementList specifies or indicates the bands that should be measured using the same gap period or MGRP.
[0055] Alternatively, FIG. 7 illustrates a compliant measurement configuration (MeasGapConfig) IE alternative for 3GPP release 13 for carrier aggregation (e.g., CA- MeasGapConfig-r1 3 ID) 700. The first option could be to add another measurement gap in the existing IE, as provided above in FIG. 6 although a new measurement gap configuration CA-MeasGapConfig-r1 3 IE for the CA 700 could be demonstrated with at least some similar content as IE 600 of FIG. 6. For example, the gap repetition period 702 could be 40ms and 80ms, as well as have one or more spares for optional or future extension. Additionally, the MeasGapConfig-r13 IE can further comprise a
measurement gap offset 704, which can indicate when the gap has started for further measurement and is based on the gap pattern repetition period selected. A band measurement list (bandMeasurementList) 706 further includes which measurement Band the UE should measure using that measurement gap or measurement gap pattern.
[0056] FIG. 8 illustrates another gap pattern 800 that can enable the increase downlink data efficiency among network devices (e.g., eNB(s) and UE(s)). The UE serving Bands are Bands A + B 302 and 502 as above. RF chainl 402 (RF_1 ) supports serving Band A 302 in addition to X 304 and Y 306. RF chain2 404 (RF_2) supports serving Band B 502 in addition to Z 308 and L 310. The UE device 1 14, for example, can thus perform measurement on Band X 304 and Z 308 simultaneously using both RF chainl 402 and RF chain2 404 in the first measurement gap slot 504. Similarly, the UE device 1 14 can also perform measurement on Band Y 306 and L 310 simultaneously in the third measurement gap time slot 508. With the same measurement performance, the UE device 1 14 can now can facilitate or enable downlink data on Bands A + B 302 and 502 in the second measurement gap slot 506 and the fourth measurement gap slot 4 510.
[0057] As such, a network device can utilize the measurement gap pattern 800 as a CA specific gap pattern to increase downlink data efficiency over other measurement gap patterns (e.g., as shown above). The network or ND can thus configure a similar data pattern to the UE device 1 14 as in above figures. However, instead of allowing the UE device 1 14 to produce more measurements utilizing the RF chains, the network can send down data to the UE device 1 14 during some of the gap patterns as a configured compromise. The decision from the eNB or other network device or entity, for example, can be based on the network conditions, requests or status reports for which resources are most desired, a reduced delay, an increased data efficiency / transmission, or a combination of both, for example.
[0058] FIG. 9 illustrates another example of a measurement gap pattern 900 that can utilize both advantages discussed above, an increase in data efficiency / transmission and a reduction in delay via one or more network devices (e.g., eNB 102, ND 1 14, or other ND). The previously discussed measurement gap pattern 800 of FIG. 8 increased data transmission to allow data to go through in the downlink between some of the data measurement gaps, such as at every other measurement gap or measurement gap time slot. The measurement gap pattern 900 enables data transmission in a mini-gap or small gap pattern fashion, while keeping downlink data and measurement of bands continuous.
[0059] In the measurement gap pattern 900, the UE device 1 14, for example, can indicate the band that it can support and simultaneously allow different RF chains to have downlink data with the compromise being the interruptions 902 and 904. The network, the network device 102, or other network device, for example, can transmit within the measurement gaps 504, 506, 508, and 510 with mini-gap pattern and interruption time an alternate RF chainl or 2 (e.g., RF chains 402 and 404). The UE device 1 14 can be configured to operate on the serving Bands A and B 302 and 502. When the UE device 1 14, for example, uses RF chainl 402 to measure Band X 304, serving Band A 302 has no data transmission. However, the UE device 1 14 can still receive downlink data in Band B using RF chain2 404 with interruptions 902 and 904 during RF tuning.
[0060] In each measurement gap 504, 506, 508, and 510, the UE device 1 14 can measure one Band (e.g., X, Y, Z, or L) at a time, which means that the UE device 1 14 still has one free RF chain to also receive data. As such, if the UE device 1 14 is preforming a CA, then what the network can do is send data in the Band that corresponds with or can be covered by the RF chain that the UE device 1 14 has available or free. Because the measurement is simultaneously happening with the data transmission, there are interruptions of about 1 ms, which are indicated in a cross pattern square of FIG. 9, where t the network will not be able to downlink data. The measurement gap pattern 900 is thus is referred to as a mini-gap pattern because when the UE device 1 14 is tuning into the RF chain, it creates an interruption to other frequency Bands that disrupts the data if the network is sending the data. In 6ms delay periods, the network can actually only send 4ms of data. In each message gap, it is the same thing for the rest of the figure. The network sends the data using the free RF of the UE device 1 14.
[0061] Referring now to FIGs. 10 and 11 , illustrated are additional standard modifications or data sets for the lEs 1000 and 1 100 to enable the mini gap
configuration or measurement gap pattern IE 900 of FIG. 9, for example. The modification for example can be submitted in TS 36.331 for enabling measurement gap configurations. The data slots or indications of the CA-gapO 1 002 include a
gapRepititionPeriod 1004, a gapOffset-r13 1006, a servingBand 1008 and a Boolean minigap 1010. If the minigap is set to true or active, then the network will send data to the RF via those RFs that are free, if not then during those datalink transmission then it will not have data transmission and the UE will either perform more measurements to reduce measurement delay.
[0062] FIG. 11 provides an alternative example for an entirely different IE for the mini gap measurement patter rather than modifying the existing IE in the 3GPP standards TS 36.331 .
[0063] While the methods described within this disclosure are illustrated in and described herein as a series of acts or events, it will be appreciated that the illustrated ordering of such acts or events are not to be interpreted in a limiting sense. For example, some acts may occur in different orders and/or concurrently with other acts or events apart from those illustrated and/or described herein. In addition, not all illustrated acts may be required to implement one or more aspects or embodiments of the description herein. Further, one or more of the acts depicted herein may be carried out in one or more separate acts and/or phases.
[0064] Referring to FIG. 12, illustrated is an example process flow for a method 1200 or a computer-readable media comprising executable instructions that, in response to execution, cause a network device or system comprising one or more processors to perform operations of the method.
[0065] At 1202, the process flow includes identifying, via the one or more processors of a network device, a measurement object identifier (ID) (measObject) and a
measurement gap pattern. The measurement gap pattern can be determined, for example according to an identification of or an identifying, via one or more processors of a network device, an indication of a UE capability related to a radio frequency (RF)- band capability (e.g., a single RF chain or multiple RF chains and corresponding band coverages of each). The identifying processes can be performed further via a control circuitry component of the network device to identify a MeasGapConfig IE, a gap offset that includes information for a choice/selection of a gap repetition periods among different gap repetition periods to support a carrier aggregation measurement gap pattern, a gap repetition period and a supporting band list that indicates a first set of frequency bands to be measured over a second set of frequency bands.
[0066] At 1204, the process flow continues with transmitting or receiving, via the one or more processors of the network device, the measObject and the measurement gap pattern via one or more radio resource control (RRC) signals. The transmitting or receiving, via a transmit circuitry component of the network device, based on the indication, a measurement gap configuration (MeasGapConfig) on an information element (IE) via the one or more radio resource control (RRC) signals.
[0067] In other embodiments, the process flow can also include identifying, via a control circuitry component of the network device, with a MeasGapConfig IE, a gap offset, a gap repetition period, a serving band (servingBand) and whether a mini gap or a full gap that is a larger measurement gap than the mini gap based on one or more downlink data.
[0068] Based on an indication or report of the UE capability, a desired
implementation or request for resources, the process flow can operate according to path A or B. Path A can continue in order to reduce interruption, while path B can continue to provide both less interruption time and an increase in data flow. Option path A can facilitate further along path C, as shown below, based on a need by one or more network devices to balance between a reduction in delay and the need for data. All option paths can also be selected according to the UE capability such as having one RF chain or more, as well corresponding band frequencies each is capable of covering in operation.
[0069] Referring to FIG. 13, illustrated is an example measurement gap pattern process flow 1300 that continues from process flow 1200 of FIG. 12 according to a selection of measurement gap pattern (e.g., via MeasGapConfig IE 600 or 700 for pattern 500) process flow A.
[0070] At 1302, the process flow 1300 continues at the selection of process flow A with facilitating a first band measurement at a first measurement gap and a second band measurement at a second measurement gap, via a first radio circuitry ( e.g., RF chainl 420) component.
[0071] At 1304, the process flow 1300 continues with facilitating a third band measurement at the first measurement gap, and a fourth band measurement at the second measurement gap, via a second radio circuitry component.
[0072] The process flow 1300 can the end or further enable additional process step C at FIG. 14. At 1402, the process flow 1400 can further comprise providing an indication (e.g., MeasGapConfig IE 600 or 700 for pattern 800) to enable downlinking of data during an additional measurement gap between the first measurement gap and the second measurement gap on the first radio circuitry component and the second radio circuitry component.
[0073] FIG. 15 illustrates a method 1500 according to a selection of path A of FIG. 12 for a measurement gap pattern including a mini gap in accordance with various aspects or embodiments herein. The method 1500 can represent, for example, measurement gap pattern having a minigap that can be indicated by MeasGapConfig IE 1000 or 1 100 for pattern 900.
[0074] At 1502, the method 1 500 includes facilitating a first band measurement at a first measurement gap, a second band measurement at a second measurement gap, and a first serving band to downlink data at the second measurement gap and a fourth measurement gap, via a first radio circuitry component (e.g., RF chainl 402).
[0075] At 1504, method 1500 continues with facilitating a downlink of data on a second serving band at the first measurement gap, a third band measurement at a third measurement gap, and a fourth band measurement at a fourth measurement gap, via a second radio circuitry component (e.g., RF chain2 404).
[0076] In one embodiment, the downlink of the data can comprise a mini gap pattern of interruption time. One or more gaps can be tolerated during the downlink for data in order to keep data flow continuous and band measurement ongoing as the mini gap pattern. Each minigap, for example, can include a pause in downlink data in order for a transition to an RF serving band or chain. In this case, RF chainl 402 (the first radio circuitry component) can operate with a pause of no data link and measurement at the third measurement gap, and RF chain2 404 (the second radio circuitry component) can operate with the same pause in DL data and measurement at the second measurement gap. The sequence between the two RF chains can then recycle.
[0077] FIG. 16 illustrates an electronic device 1600 in accordance with various aspects disclosed herein. The electronic (network) device 1600 can be incorporated into or otherwise part of, an eNB (e.g., 102), a UE (e.g., 1 14), or some other type of electronic or network device in accordance with various embodiments. Specifically, the electronic device 1 600 can be logic or circuitry that can be at least partially implemented in one or more of hardware, software, or firmware. In embodiments, the electronic device 1600 logic can include radio transmit logic component 1 602 and receive logic component 1606 coupled to control logic component 1604. In embodiments, the transmit or receive logic components can be elements or modules of a transceiver, a transmitter, or receiver chain, as shown. The electronic device 1602 can be coupled with or include one or more plurality of antenna elements 1608 of one or more antennas. The electronic device and/or the components of the electronic device can be configured to perform operations similar to those described elsewhere in this disclosure.
[0078] In embodiments where the electronic device circuitry is a network entity or is incorporated into or otherwise part of a network entity, the control circuitry component 1604 can be configured to identify a measurement object identifier (ID) (measObject) and a measurement gap pattern. The transmit circuitry component 1602 can be configured to transmit an indication of the measObject and the measurement gap pattern to a user equipment (UE) via one or more radio resource control (RRC) signals. In addition, the receive circuitry component 1606 (e.g., RF chainl 402 and RF chain2 404) can be configured to receive, via one or more radio resource control (RRC) signals, a measurement gap configuration (MeasGapConfig) on a MeasGapConfig information element (IE) that controls measurements during a plurality of measurement gaps using a carrier aggregation.
[0079] As used herein, the term "logic" can refer to, be part of, or include
an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), and/or memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable hardware components that provide the described functionality. Specifically, the logic can be at least partially implemented in, or an element of, hardware, software, and/or firmware. In some embodiments, the electronic device logic may be implemented in, or functions associated with the logic may be implemented by, one or more software or firmware modules.
[0080] Embodiments described herein can be implemented into a system using any suitably configured hardware and/or software. FIG. 17 illustrates, for one embodiment, an example system comprising radio frequency (RF) logic 1702, baseband logic 1 704, application logic 1706, memory/storage 1708, display 1710, camera 1712, sensor 1714, and input/output (I/O) interface 171 6, coupled with each other at least as shown.
[0081] The application logic 1 706 can include one or more single-core or multi-core processors. The processor(s) can include any combination of general-purpose processors and dedicated processors (e.g., graphics processors,

[0082] The baseband logic 1704 can include one or more single-core or multi-core processors. The processor(s) can include a baseband processor 1718 and/or additional or alternative processors 1720 that can be designed to implement functions or actions of the control logic, transmit logic, and/or receive logic described elsewhere herein. The baseband logic 1704 can handle various radio control functions that
enable communication with one or more radio networks via the RF logic. The radio control functions can include, but are not limited to, signal modulation, encoding, decoding, radio frequency shifting, etc. In some embodiments, the baseband logic can provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband logic 1704 can support communication with an evolved universal terrestrial radio access network (EUTRAN) and/or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN). Embodiments in which the baseband logic 1704 is configured to support radio communications of more than one wireless protocol can be referred to as multi-mode baseband logic.
[0083] In various embodiments, baseband logic 1704 can include logic to
