FIELD OF REVELATION

[0002] The present disclosure, for example, relates to wireless communication systems and, more particularly, to techniques for performing half-duplex/full-duplex operations in wireless communications.

BACKGROUND TO THE REVELATION

[0003] Wireless communication networks are widely employed to provide various communication services such as voice, video, packet data, messaging, broadcast, etc. These wireless networks can be multi-access networks capable of supporting multiple users by sharing available network resources. Examples of such multi-access networks include Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, orthogonal FDMA networks ( OFDMA) and Single Carrier FDMA (SC-FDMA) networks.

[0004] A wireless communication network may include multiple base stations (e.g., eNodeBs) that may support communication to multiple user equipment (UEs). A UE can communicate with a base station via the downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE and the uplink (or reverse link) refers to the communication link from the UE to the base station.

[0005] To improve wireless communications performance, it may be desirable to allow a UE to communicate simultaneously with multiple base stations via multiple uplink grants from the base stations, which may be referred to as wireless communications with multiple connectivity or, more specifically, dual connectivity, where the UE communicates via uplink grants from two base stations. The UE may then use one or more carriers to communicate with one or more cells of each of the multiple base stations.

SUMMARY OF THE REVELATION

[0006] Aspects of the present disclosure relate, generally, to wireless communications and, more particularly, to techniques for performing half-duplex/full-duplex operations in multiple connectivity wireless communications. For example, techniques for performing half-duplex or full-duplex operations when communicating with multiple cells configured by multiple base stations are described herein.

[0007] According to one aspect, a wireless device (e.g., user equipment (UE)) can communicate with multiple cells (e.g., PCell or SCell) configured by one or more base stations (e.g., one primary eNodeB (MeNodeB or MeNB) and at least one secondary eNodeB (SeNodeB or SeNB) in multi-connectivity wireless communications) in a wireless network. In an example, based on the carrier configuration for a particular one of multiple cells configured by one or more base stations, the wireless device may determine whether it can perform half-duplex or full-duplex operations. with a given one of the multiple cells configured by one or more base stations. In another example, based on a capability of the wireless device, the wireless device may determine the possibility that it can perform half-duplex or full-duplex operations with a given of multiple cells configured by one or more stations. -base. Where the carrier configuration of the multiple cells allows the wireless device to perform half-duplex operations, however, because the wireless device communicates with multiple cells configured by multiple base stations, there may be cases where the device itself wireless may be performing full duplexing operations by transmitting to one of the multiple cells configured by one of one or more base stations while receiving from another of the multiple cells. Thus, by utilizing multiple connections to multiple cells configured by one or more base stations, the wireless device can perform full duplex operations even when the individual connections may be configured only for half duplex operations (for example, in a certain time interval or otherwise). Furthermore, in one example, this may be applied to the case of carrier aggregation where multiple connections are established on multiple component carriers configured by the same base station (e.g., where the carriers may have dedicated bandwidth configurations) .

[0008] In one example, a method for communicating using multiple connectivity wireless communications in a wireless network is provided. The method includes communicating with a first cell served by a first access point over a first connection, communicating with a second cell served by a second access point over a second connection, determining the feasibility of performing a first half duplex operation or a first full duplex operation for communication with the first cell served by the first access point over the first connection and determining whether to perform a second half duplex operation or a second full duplex operation for communication with the second cell served by the second access point over the second connection.

[0009] The method may also include performing a full duplex operation by communicating with one of the first cell over the first connection or the second cell over the second connection to receive communications as part of the full duplex operation and communicating with the other between the first cell over the first connection or the second cell over the second connection to transmit communications as part of the full duplexing operation. The method may additionally include the first connection and the second connection that support only half duplex operations in a time interval related to performing the full duplex operation.

[0010] The method may also include at least one of determining the possibility of performing the first half duplex operation or the first full duplex operation for communication with the first cell or determining the possibility of performing the second half duplex operation. duplexing or the second full duplexing operation for communication with a second cell that is based at least in part on a configuration. Furthermore, the method may include configuration that refers to a carrier aggregation bandwidth configuration of a respective one of the first connection and the second connection. The method may further include configuration that refers to one or more capabilities of a user equipment (UE) for communicating using a respective one of the first connection and the second connection. Additionally, the method may include determining whether to perform the second half-duplex operation or the second full-duplex operation for communicating with the second cell comprising determining whether to perform the second full-duplex operation based at least in part in determining the transmit power for the second full duplexing operation to be less than a threshold power. The method may also include the first access point and the second access point that are the same as the same access point.

Furthermore, the apparatus may include configuration that refers to a carrier aggregation bandwidth configuration of a respective one of the first connection and the second connection. The apparatus may also include configuration that refers to one or more capabilities of a UE for communicating with the use of a respective one of the first connection and the second connection. The apparatus may further include the half-duplex/full-duplex operation component that is configured to determine whether to perform the second half-duplex operation or the second full-duplex operation for communication with the second cell at least in part by determining to perform the second full duplexing operation based at least in part on determining a transmit power for the second full duplexing operation to be less than a threshold power.

The apparatus may additionally include the first connection and the second connection that support only half duplex operations in a time interval related to performing the full duplex operation with the first cell and the full duplex operation with the second cell.

[0016] Furthermore, the apparatus may include the means for determining the possibility of performing the first half duplex operation or the first full duplex operation for communication with the first cell or the means for determining the possibility of performing the second operation of half duplex or second full duplex operation for communication with second cell which are determined based at least in part on a configuration. The apparatus may also include configuration that refers to a carrier aggregation bandwidth configuration of a respective one of the first connection and the second connection. The apparatus may also further include configuration that refers to one or more capabilities of a UE for communicating with the use of a respective one of the first connection and the second connection. The apparatus may also include the first access point and the second access point that are the same as the same access point.

DETAILED DESCRIPTION

[0030] The detailed description presented below, in connection with the attached drawings, is intended to describe various configurations and is not intended to represent only the configurations in which the concepts described in this document can be practiced. The detailed description includes details for the purpose of providing a complete understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0031] Various methods, apparatus, devices and systems are described for performing half duplex/full duplex operations by using multiple connections in carrier aggregation or in a multiple connectivity communication mode. In some aspects, a wireless device (e.g., user equipment (UE)) may communicate with multiple cells configured by multiple network entities using multiple connectivity communication mode, which may include receiving resources for each of the multiple network entities through which the wireless device can communicate when accessing a wireless network. In some aspects, a wireless device may receive first configuration information to communicate with a first network entity (e.g., a primary eNodeB, also referred to as a MeNodeB or MeNB) through a first primary cell (e.g., the primary cell group primary cell or PCell) of the first network entity. The wireless device may receive second configuration information to communicate with a second network entity (e.g., a secondary eNodeB, also referred to as a SeNodeB or SeNB) through a second primary cell (e.g., a group primary cell). of secondary cells or PCellsco) of the second network entity. For each of the first primary cell and the second primary cell, the wireless device may determine whether to perform the half-duplex or full-duplex operation based at least in part on the first configuration information and the second configuration information. configuration, respectively. The second network entity may not be co-located with the first network entity, co-located with the first network entity, and/or may be the same as the first network entity (e.g., in carrier aggregation with a single eNodeB).

[0032] In some aspects of multiple connectivity wireless communications, a wireless device may be communicatively coupled to a plurality of network entities. For example, a first network entity (e.g., a master eNodeB, also referred to as a MeNodeB or MeNB) may be configured to operate a master cell group (MCG) that includes one or more cells (e.g., each cell may operate in different frequency bands and may include one or more component carriers (CCs)). A cell in the main cell group (MCG) can be configured as a first primary cell (for example, PCellMCo) of the main cell group (MCG). A second network entity (e.g., SeNodeB or SeNB) may be configured to operate a secondary cell group (SCG) that includes one or more cells (e.g., each cell may operate in different frequency bands and may include one or more more CCs). A cell in the secondary cell group (SCG) can be designated as a first primary cell (e.g., PCellSCG) of the secondary cell group (SCG). For example, the wireless device may receive configuration information from the first network entity through the first primary cell (e.g., PCellMco) and configuration information from the second network entity through the second primary cell (e.g., PCellsco)- The first network entity cannot be co-located with the second network entity, co-located with the first network entity and/or may be the same as the first network entity (e.g. in carrier aggregation with a single eNodeB) .

[0033] In one aspect, carrier aggregation may be permitted within each of the cell or cell groups configured by the MeNB and SeNB and/or related cells and the wireless device may perform half-duplex or full-duplex operations. with one or more of the cell groups or cell configured by the MeNB and SeNB based on at least one of the carrier aggregation band configuration determined for the wireless device with the respective eNB and/or wireless device capabilities determined by the carrier aggregation band configuration. Furthermore, the wireless device may be capable of performing full duplex operations in this configuration even when only half duplex operations can be performed with the cell groups or cell configured by the MeNB and/or SeNB individually due to the fact that, When considered through MeNB and SeNB, the wireless device can contemporaneously transmit to one eNB and receive from the other eNB in a certain time interval. It should be appreciated that a wireless device can also operate as full duplex in carrier aggregation with a single eNB in which the multiple carriers or carrier groups of the aggregated carriers can have dedicated band configurations that can allow half duplex operations.

[0034] The techniques described in this document can be used by various wireless communication networks such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can deploy a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Broadband CDMA (WCDMA) and other CDMA variants. cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can deploy a radio technology such as the Global System for Mobile Communications (GSM). An OFDMA network can deploy radio technology such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of UMTS. 3 GPP LTE and LTE Advanced (LTE-A) are new UMTS releases that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization called the “3rd Generation Partnership Project” (3GPP). cdma2000 and UMB are described in documents from an organization called “3rd Generation Partnership Project 2” (3GPP2). The techniques described in this document can be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For the purpose of clarity, certain aspects of the techniques are described below for LTE and the LTE terminology is used throughout much of the description below.

[0035] Figure 1 is a block diagram that conceptually illustrates an example of a wireless communications system 100, in accordance with an aspect of the present disclosure. The wireless communications system 100 includes base stations (or cells) 105, user equipment (UEs) 115, and a core network 130. The base stations 105 can communicate with the UEs 115 under control of a wireless communications system 100. base station (not shown), which may be part of the core network 130 or base stations 105 in various embodiments. One or more UEs 115 may include a communication component 640 to perform half-duplex/full-duplex operations in multi-connectivity wireless communications and/or carrier aggregation (with one or more base stations), as described herein. The base stations 105 may communicate control information and/or user data with the core network 130 via the first return traffic links 132. In embodiments, the base stations 105 may communicate, either directly or indirectly, to each other via second return traffic links 134, which may be wired or wireless communication links. The wireless communications system 100 may support operation on multiple carriers (waveform signals of different frequencies). Multi-carrier transmitters can transmit modulated signals simultaneously on multiple carriers. For example, each communication link 125 may be a multi-carrier signal modulated in accordance with the various radio technologies described above. Each modulated signal can be sent on a different carrier and can carry control information (e.g. reference signals, control channels, etc.), projection information, data, etc. The wireless communications system 100 may also support operation on multiple streams at the same time. In some aspects, the multiple streams may correspond to multiple wireless wide area networks (WWANs) or cellular streams. In other aspects, the multiple streams may correspond to a combination of WWANs or cellular streams and wireless local area networks (WLANs) or Wi-Fi streams.

[0036] The base stations 105 may communicate wirelessly with the UEs 115 via one or more base station antennas. Each of the base station locations 105 may provide communications coverage for a respective geographic coverage area 110. In some embodiments, the base stations 105 may be referred to as a base transceiver station, a radio base station, a access point, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a NodeB, eNodeB, Home NodeB, a Home eNodeB, or other suitable terminology. The geographic coverage area 110 for a base station can be divided into sectors that form only a portion of the coverage area (not shown). The wireless communications system 100 may include base stations 105 of different types (e.g., macro, micro, and/or pico base stations). There may be overlapping coverage areas for different technologies.

[0037] In deployments, the wireless communications system 100 is an LTE/LTE-A network communications system. In LTE/LTE-A network communication systems, the term evolved Node B (eNodeB) may be used to describe the base stations 105. The wireless communication system 100 may be an LTE/LTE-A Heterogeneous Network in which different types of eNodeBs provide coverage for different geographic regions. For example, each of the eNodeBs 105 may provide communications coverage for a macrocell, a picocell, a femtocell, and/or other cell types. A macrocell may span a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 115 with service subscriptions with the network provider. A picocell may cover a relatively smaller geographic area (e.g., buildings) and may allow unrestricted access by UEs 115 with service subscriptions with the network provider. A femtocell may also span a relatively smaller geographic area (e.g., a residential home) and, in addition to unrestricted access, may also provide restricted access by UEs 115 that have an association with the femtocell (e.g., the UEs 115 in a group of closed subscribers (CSG), UEs 115 for users at home and the like). An eNodeB 105 for a macrocell can be called a macro-eNodeB. An eNodeB for a picocell can be called a pico-eNodeB. And, an eNodeB for a femtocell can be called a femto-eNodeB or an initial eNB. An eNodeB 105 may support one or multiple (e.g., two, three, four, and the like) cells. The wireless communications system 100 may support the use of LTE and WLAN or Wi-Fi by one or more of the UEs 115.

[0038] The core network 130 may communicate with the eNodeBs 105 or other base stations 105 via the first return traffic links 132 (e.g., SI interface, etc.). The eNodeBs 105 may also communicate, for example, directly or indirectly via second return traffic links 134 (e.g., X2 interface, etc.) and/or via first return traffic links 132 (e.g., example, via the main network 130). The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, the eNodeBs 105 may have similar frame timing, and transmissions from different eNodeBs 105 may be approximately aligned in time. For asynchronous operation, the eNodeBs 105 may have different frame timing, and transmissions originating from different eNodeBs 105 may not be time aligned. The techniques described in this document can be used for both synchronous and asynchronous operations.

[0039] The UEs 115 may be dispersed throughout the wireless communications systems 100, and each UE 115 may be stationary or mobile. A UE 115 may also be referred to by those skilled in the art as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client or some other suitable terminology. A UE 115 may be a cellular telephone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet-type computer, a laptop-type computer, a cordless telephone , a wireless local loop station (WLL) or similar. A UE 115 may have the ability to communicate with macro eNodeBs, pico eNodeBs, femto eNodeBs, relays, and the like.

[0040] The communication links 125 shown in the wireless communications system 100 may include uplink (UL) transmissions from a UE 115 to an eNodeB 105, and/or downlink (DL) transmissions, from an eNodeB 105 to a UE 115. Downlink transmissions may also be called forward link transmissions while uplink transmissions may also be called reverse link transmissions.

[0041] In certain aspects of the wireless communications system 100, a UE 115 may be configured to support carrier aggregation (CA) with two or more eNodeBs 105. The eNodeBs 105 that are used for carrier aggregation may be positioned or can be connected via quick connections. In either case, coordination of aggregation of component carriers (CCs) for wireless communications between the UE 115 and the eNodeBs 105 can be performed more easily because information can be shared readily among the various cells that are used to perform carrier aggregation. When the eNodeBs 105 that are used for carrier aggregation are not co-located (e.g., too far apart or do not have a high-speed connection to each other), then the coordination of component carrier aggregation may involve additional aspects. For example, in carrier aggregation for dual connectivity (e.g., UE 115 connected to two non-placed eNodeBs 105), the UE 115 may receive configuration information to communicate with a first eNodeB 105 (e.g., SeNodeB or SeNB) through of a primary cell of the first eNodeB 105. The first eNodeB 105 may include a group of cells referred to as a secondary cell group or SCG, which includes one or more secondary cells and the primary cell or PCellSCG of the first eNodeB 105. The UE 115 may also receive configuration information to communicate with a second eNodeB 105 (e.g., MeNodeB or MeNB) through a second primary cell of the second eNodeB 105. The second eNodeB 105 may include a group of cells referred to as a primary cell group or MCG, which includes one or more secondary cells and the primary cell or PCellSCG of the second eNodeB 105.

[0042] In certain aspects of the wireless communications system 100, carrier aggregation for dual connectivity may involve having a secondary eNodeB 105 (e.g., SeNodeB or SeNB) that is configured to operate one of its cells as a PCellSCG. The secondary eNodeB 105 may transmit, to a UE 115, configuration information via the PCellSCG for the UE 115 to communicate with the secondary eNodeB 105 while the UE 115 is in communication with a primary eNodeB 105 (e.g., MeNodeB or MeNB) . The main eNodeB 105 may transmit, to the same UE 115, configuration information via its PCell so that the UE 115 communicates with the other eNodeB 105. The two eNodeBs 105 may not be co-located.

[0043] In examples described herein, a UE 115 may be configured with an AC band from the eNodeBs 105. For example, the communication component 640 may receive configuration from one or more of the eNodeBs 105 and/or or may use the configuration in communication with one or more of the eNodeBs 105, as described in this document. Based on the AC band configuration and/or capabilities of UE 115, the UE 115 may perform half-duplex or full-duplex operations with the eNodeBs 105. Additionally, in some examples, the UE 115 may perform full-duplex operations. over the network when half-duplex operations are supported by the eNodeBs 105 by using a connection to at least one of the multiple eNodeBs 105 to transmit wireless network communications in a given time slot while using a connection to at least one other of the multiple eNodeBs 105 to receive wireless network communications in the given time slot. Furthermore, in an example, where one of the eNodeBs 105 is a small cell capable of receiving transmission from the UE 115 under a threshold transmit power, the UE 115 may configure full duplexing operations upon connection to the small cell eNodeB. 105 by transmitting to the small cell eNodeB 105 using a transmission power below the threshold.

[0044] Figure 2 is a block diagram that conceptually illustrates examples of an eNodeB 210 and a UE 250 configured in accordance with an aspect of the present disclosure. For example, the base station/eNodeB 210 and the UE 250 of a system 200, as shown in Figure 2, may be one of the base stations/eNodeBs and one of the UEs in Figures 1, respectively. Accordingly, the UE 250 may include a communication component 640 to perform half-duplex/full-duplex operations in multiple connectivity and/or carrier aggregation wireless communications (with one or more eNBs 210), as described herein. In some aspects, the eNodeB 210 may support carrier aggregation and/or multiple connectivity carrier aggregation (e.g., dual connectivity). For example, the eNodeB 210 may be a MeNodeB or MeNB that has one of the cells in its MCG configured as a PCell, may be a SeNodeB or SeNB that has one of its cells in its SCG configured as a PCellsco, may have one of the cells on your MCG/SCG configured as a SCell, etc. In some aspects, the UE 250 may also support carrier aggregation, multiple connectivity carrier aggregation, etc. The UE 250 may receive configuration information from the eNodeB 210 through PCell and/or PCellsco, which may refer to a bandwidth configuration based on one or more capabilities indicated by the UE 250, as further described herein. The base station 210 may be equipped with antennas 2341-t and the UE 250 may be equipped with antennas 2521-r, wherein t and r are integers greater than or equal to one.

[0045] At base station 210, a base station transmission processor 220 may receive data from a base station data source 212 and control information from a base station controller/processor 240. The information control channels can be conducted on PBCH, PCFICH, physical hybrid automatic request/retry (HARQ) indicator channel (PHICH), PDCCH, etc. Data can be driven into PDSCH, etc. The base station transmission processor 220 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The base station transmission processor 220 may also generate reference symbols, for example, for the PSS, SSS, and cell-specific reference signal (RS). A base station multi-input multiple-output (MIMO) transmission (TX) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, and/or reference symbols, if applicable, and can provide output symbol streams to 2321-t base station modulators/demodulators (MODs/DEMODs). Each base station modulator/demodulator 232 may process a respective stream of output symbols (e.g., for OFDM, etc.) to obtain a stream of output samples. Each base station modulator/demodulator 232 may further process (e.g., convert to analog, amplify, filter, and widen) the output sample stream to obtain a downlink signal. The downlink signals from the modulators/demodulators 2321-t can be transmitted through the antennas 2341-t, respectively.

[0046] In the UE 250, the UE antennas 2521-r can receive the downlink signals from the base station 210 and can provide received signals to the UE modulators/demodulators (MODs/DEMODs) 2541-r, respectively. Each UE 254 modulator/demodulator may condition (e.g., filter, amplify, reduce, and digitize) a respective received signal to obtain input samples. Each UE modulator/demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector of UE 256 may obtain received symbols from all modulators/demodulators of UE 2541-r and receive MIMO detection on the received symbols, if applicable, and provide detected symbols. A UE receiving processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide the decoded data for the UE 250 to a data sink 260, and provide decoded control information to a controller/processor. of EU 280.

[0047] On the uplink, in the UE 250, a UE transmission processor 264 may receive and process data (e.g., for the PUSCH) from a source of UE 262 data and control information (e.g., for the PUCCH) from the UE controller/processor 280. The UE transmit processor 264 may also generate reference symbols for a reference signal. Symbols from the UE transmit processor 264 may be pre-coded by a UE TX MIMO processor 266, if applicable, further processed by the UE modulators/demodulators 2541-r (e.g., for SC-FDM, etc.) and transmitted to base station 210. At base station 210, uplink signals from UE 250 may be received by base station antennas 234, processed by base station modulators/demodulators 232, detected by a base station MIMO detector 236, if applicable, and further processed by a base station receive processor 238 to obtain decoded data and control information sent by the UE 250. The base station receive processor 238 may providing the decoded data to a base station data collector 246 and the decoded control information to the base station controller/processor 240.

[0048] The base station controller/processor 240 and the UE controller/processor 280 may direct operation at the base station 210 and the UE 250, respectively. The UE controller/processor 280 and/or other processors and modules in the UE 250 may also perform or direct, for example, the execution of the functional blocks illustrated in Figure 6 and/or other processes for the techniques described herein (e.g. , flowcharts illustrated in Figure 7). In some aspects, at least a portion of the execution of these functional blocks and/or processes may be performed by block 281 in UE controller/processor 280. Base station memory 242 and UE memory 282 may store data and program codes. for the base station 210 and the UE 250, respectively. For example, UE memory 282 may store configuration information for multi-connectivity wireless communications provided by base station 210 and/or another base station. A scheduler 244 can be used to program the UE 250 for data transmission on the downlink and/or uplink.

[0049] In one configuration, the UE 250 may include means for communicating with a first cell served by a first access point over a first connection. The UE 250 may also include means for communicating with a second cell served by a second access point over a second connection. The UE 250 may further include means for determining whether to perform a half duplex operation or a full duplex operation for communicating with the first cell served by the first access point over the first connection. The UE 250 may also include means for determining whether to perform a half duplex operation or a full duplex operation for communicating with the second cell served by the second access point over the second connection. In one aspect, the aforementioned means may be the UE controller/processor 280, the UE memory 282, the UE receive processor 258, the UE MIMO detector 256, the UE modulators/demodulators 254, and the antennas. of UE 252 configured to perform the aforementioned functions by the aforementioned means. In another aspect, the aforementioned means may be a module, component or any apparatus configured to perform the functions mentioned by the aforementioned means. Examples of such modules, components or apparatus can be described in relation to Figure 6.

[0050] Figure 3 is a block diagram that conceptually illustrates an aggregation of carriers and/or connections in a UE, in accordance with an aspect of the present disclosure. Aggregation may occur in a system 300 that includes a multi-mode UE 315, which may communicate with an eNodeB 305-a using one or more component carriers 1 to N (CC1-CCN), and/or with a secondary eNB 305b using one or more M to P component carriers (CCM-CCP). For example, the eNodeB 305-a and/or secondary eNB 305-b may include an AP, femtocell, picocell, etc. UE 315 may include a communication component 640 to perform half-duplex/full-duplex operations in multiple connectivity and/or carrier aggregation wireless communications (with one or more eNBs 210), as described herein. The UE 315 may be a multi-mode UE in this example that supports more than one radio access technology (RAT). For example, the UE 315 may support at least one WWLAN radio access technology (e.g., LTE) and one WLAN radio access technology (e.g., Wi-Fi). A multi-mode UE may also support carrier aggregation and/or multi-connectivity carrier aggregation as described herein. The UE 315 may be an example of one of the UEs of Figure 1, Figure 2, Figure 4a, Figure 4b, Figure 5, Figure 6. The eNodeB 305-a and/or secondary eNB 305-b may be a example of one of the eNodeBs or base stations of Figure 1, Figure 2, Figure 4a, Figure 4b, Figure 5, Figure 6. Although only one UE 315, one eNodeB 305-a and one secondary eNB 305 -b are illustrated in Figure 3, it will be appreciated that system 300 may include any number of UEs 315, eNodeBs 305-a and/or secondary eNBs 305-b. In an example, the UE 315 may communicate with an eNB 305-a over one or more LTE component carriers 330-1 to 330-N while communicating with another eNB 305-b over one or more of the one or more component carriers from LTE 330-M to 330-P.

[0051] The eNodeB 305-a may transmit information to the UE 315 via linear (downlink) channels 332-1 through 332-N on LTE component carriers CC1 through CCN 330. Additionally, the UE 315 may transmit information to the eNodeB 305-a over reverse (uplink) channels 334-1 to 334-N on LTE component carriers CC1 to CCN. Similarly, the eNodeB 305-b may transmit information to the UE 315 over forwarding (downlink) channels 332-m to 332-p on LTE component carriers CCM CCP 330. Additionally, the UE 315 may transmit information to the eNodeB 305-b over reverse (uplink) channels 334-m to 334-p on LTE component carriers CCM to CCP 330.

[0052] In describing the various entities of Figure 3, as well as in other Figures associated with some of the disclosed embodiments, for the purposes of explanation, the nomenclature associated with a 3 GPP LTE or LTE-A wireless network is used. However, it should be noted that system 300 may operate on other networks such as, but not limited to, an OFDMA wireless network, a CDMA network, a 3GPP2 CDMA2000 network, and the like.

[0053] In multi-carrier operations, downlink control information (DCI) messages associated with different UEs 315 may be carried on multiple component carriers. For example, the DCIs in a PDCCH may be included on the same component carrier that is configured to be used by a UE 315 physical downlink shared channel transmissions (e.g., same-carrier signaling). Alternatively or additionally, the DCI may be carried on a different component carrier than the target component carrier used for PDSCH transmissions (i.e., cross carrier signaling). In some deployments, a carrier indicator field (CIF), which may be semistatically enabled, may be included in some or all DCI formats to facilitate the transmission of PDCCH control signaling from a carrier other than the target carrier for PDSCH (transverse carrier signaling) transmissions.

[0054] In the present example, the UE 315 can receive data from an eNodeB 305-a. However, users on a cell edge may experience high cross-cell interference that can limit data rates. Multi-streaming allows UEs to receive data from two eNodeBs 305-a and 305-b simultaneously. In some aspects, the two eNodeBs 305-a may be non-colocated and may be configured to support multiple connectivity carrier aggregation. Multistream operates by sending and receiving data from the two 305-a eNodeBs in two completely separate streams when a UE is in range of two cell towers in two adjacent cells at the same time (see Figure 5 below) . The UE communicates with two eNodeBs 305-a and/or 305-b simultaneously when the device is at the edge of range of any eNodeBs. By scheduling two independent data streams to the mobile device from two different eNodeBs at the same time, multistreaming exploits a non-uniform load in wireless communication networks. This helps improve the cell edge user experience while increasing network capacity. In one example, throughput data speeds for users on a cell edge can double. In some aspects, multistreaming may also refer to the ability of a UE to communicate with a WWAN tower (e.g., cell tower) and a WLAN tower (e.g., AP) simultaneously when the UE is in range. of both towers. In such cases, the towers can be configured to support carrier aggregation across multiple connections when the towers are not collocated.

[0055] Figure 4a is a block diagram that conceptually illustrates an example of data paths 445 and 450 between a UE 415 and a PDN 440 (e.g., Internet or one or more components for accessing the Internet) in accordance with with an aspect of the present revelation. Data paths 445, 450 are shown within the context of a wireless communications system 400 for aggregating data from different eNodeBs 405 and 406, which may or may not use the same RAT. The system 200 of Figure 2 may be an example of portions of the wireless communications system 400. The wireless communications system 400 may include a multi-mode UE 415, an eNodeB 405, secondary eNodeB 406 that may couple to the eNodeB 405 via a backlink 438 (e.g., based on an X2 interface), an evolved packet core (EPC) 480, a PDN 440, and a peer entity 455. The UE 415 may include a communication component 640 to perform half-duplex/full-duplex operations in multi-connectivity wireless communications and/or carrier aggregation (with one or more base stations), as described in this document. The multi-mode UE 415 may be configured to support carrier aggregation, multi-connectivity carrier aggregation (e.g., dual connectivity), and/or the like. The EPC 480 may include a mobility management entity (MME) 430, a service communications port (SGW) 432, and a PDN communications port (PGW) 434. A home subscriber system (HSS) 435 may be communicatively coupled to the MME 430. The UE 415 may include an LTE radio 420 and an LTE radio 425. These elements may represent aspects of one or more of their counterparts described above with reference to the preceding or subsequent Figures. For example, the UE 415 may be an example of the UEs of Figure 1, Figure 2, Figure 3, Figure 5, Figure 6, etc., the eNodeB 405 may be an example of the eNodeBs/base stations of Figure 1, of Figure 2, of Figure 3, of Figure 5, of Figure 6, the eNB 406 may be an example of the secondary eNB 305-b of Figure 3 and/or the EPC 480 may be an example of the main network of Figure 1 The eNodeBs 405 and/or 406 in Figure 4a may not be positioned or may not otherwise be in high-speed communication with each other. Furthermore, in one example, eNodeBs 405 and 406 may communicate with different EPCs 480.

[0056] Referring again to Figure 4a, the eNodeB 405 and/or 406 may be capable of providing the UE 415 with access to the PDN 440 using the aggregation of one or more LTE component carriers (e.g., with a or more eNodeBs) Accordingly, the UE 415 may involve a carrier aggregation in dual connectivity, wherein one connection is to one network entity (eNodeB 405) and the other connection is to a different network entity (eNodeB 406). It should be appreciated that UE 415 may communicate with additional eNodeBs 405 and/or 406 via additional data paths 445, 450 that intersect the EPC 408 or do not access the PDN 440 to provide multi-connectivity wireless communications with multiple NodeBs, aggregation multi-cell carrier of an eNodeB, etc. Using this access to the PDN 440, the UE 415 may communicate with the peer entity 455. The eNodeB 405 and/or 406 may provide access to the PDN 440 via the EPC 480 (e.g., via data paths 445). and the eNodeB 406 may provide direct access to the PDN 440 (e.g., via data paths 450). In the described example, the UE 415 may communicate with the eNodeB 405 as a MeNodeB and the eNodeB 406 as a SeNodeB over eNodeB-specific bearers. In an example, eNodeBs 405 and 406 may communicate with each other over an and/or secondary eNodeB 406, which may map communications over data paths 445 and 450 to access PDN 440. Furthermore, in this example, MeNodeB 405 may provide UE-specific higher-layer functionality to UE 415, such as non-access layer (NAS) that include NAS security, NAS mobility functions, etc. Furthermore, in this example, the SeNodeB 406 may transport the PUCCH to the SCG and provide other lower layer functionality similar to Pcell for the SCG. In this way, the UE 415 may communicate independently with MeNodeB 405 and SeNodeB 406, which may give rise to a situation in which the UE 415 is configured for half-duplex communications with one of or both the MeNodeB 405 and the SeNodeB 406, but may be perform full duplex communications with the MeNodeB 405 and SeNodeB 406 when considered together based on the separate band configurations for MeNodeB 405 and SeNodeB 406.

[0057] The MME 430 may be the control node that processes signaling between the UE 415 and the EPC 480. The MME 430 may provide carrier and connection management. Therefore, the MME 430 may be responsible for idle mode UE paging and tracking, carrier activation and deactivation, and SGW selection for the UE 415. The MME 430 may communicate with the eNodeBs 405-a and 406-b via an SI-MME interface. The MME 430 may additionally authenticate the UE 415 and deploy Non-Access Stratum (NAS) signaling with the UE 415.

[0058] The HSS 435 may, among other functions, store subscriber data, management roaming restrictions, management accessible access point names (APNs) for a subscriber, and subscribers associated with MMEs 430. The HSS 435 may communicate with the MME 430 via an S6a interface defined by the Evolved Packet System (EPS) architecture standardized by the 3 GPP organization.

[0059] All user IP packets transmitted via LTE may be transferred via eNodeBs 405 and/or 406 to the SGW 432, which may be connected to the communications port of PGW 434 via a signaling interface S5 and the MME 430 via an S11 signaling interface. The SGW 432 can reside in the user plane and act as a mobility anchor for handovers between eNodeBs and handovers between different access technologies. The PGW 434 may provide UE IP address allocation as well as other functions.

[0060] The PGW 434 may provide connectivity to one or more external packet data networks, such as PDN 440, via an SG1 signaling interface. The PDN 440 may include the Internet, an Intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) Broadcast Service (PSS), and/or other types of PDNs.

[0061] In the present example, user plane data between the UE 415 and the EPC 480 may traverse the same set of one or more EPS bearers, regardless of whether the traffic flows over a link data path 445 or of data path 450. Signaling or control plane data related to the set of one or more EPS bearers may be transmitted between the LTE radio 420 of the UE 415 and the MME 430 of the EPC 480 via the eNodeBs 405 and /or 406.

[0062] Although the aspects of Figure 4a have been described in relation to LTE, similar aspects in relation to aggregation and/or multiple connections can also be implemented in relation to UMTS or other similar system or wireless communications radio technologies. network.

[0063] Figure 4b is a block diagram that conceptually illustrates an example of data paths 446 and 451 between the UE 415 and the EPC 480 in accordance with an aspect of the present disclosure. Data paths 446, 451 are shown within the context of a wireless communications system 401 for aggregating data from a split carrier to transmit using resources from multiple eNodeBs 405, 406. This may be a carrier configuration alternative to that shown in Figure 4a, for example, which has data paths 445 that intersect eNodeB 405 and/or data paths 450 that intersect eNodeB 406. The system 200 of Figure 2 may be an example of portions of the wireless communications system 401. The wireless communications system 401 may include a UE 415, eNodeB 405, an eNodeB 406, an evolved packet core (EPC) 480, a PDN 440, and a peer entity 455. The UE 415 may include a communication 640 to perform half-duplex/full-duplex operations in multi-connectivity wireless communications and/or carrier aggregation (with one or more base stations), as described herein. The UE 415 may be configured to support carrier aggregation, multiple connectivity carrier aggregation (e.g., dual connectivity), etc. It should be appreciated that the UE 415 may be a multi-mode UE that may communicate with eNodeBs 405 and/or 406 together with a WLAN AP (not shown for ease of explanation). The EPC 480 may include a mobility management entity (MME) 430, a service communications port (SGW) 432, and a PDN communications port (PGW) 434. A home subscriber system (HSS) 435 may be communicatively coupled to the MME 430. The UE 415 may include an LTE radio 420, it should be appreciated that the LTE radio 420 may comprise one or more radios (e.g., LTE radios 420, 425 in Figure 4a). These elements may represent aspects of one or more of their counterparts described above with reference to the preceding or subsequent Figures. For example, the UE 415 may be an example of the UEs of Figure 1, of Figure 2, of Figure 3, of Figure 5, of Figure 6, the eNodeBs 405, 406 may be an example of the eNodeBs/base stations of Figure 1 , of Figure 2, of Figure 3, of Figure 5, of Figure 6 and/or the EPC 480 may be an example of the main network of Figure 1. The eNodeBs 405, 406 in Figure 4b may or may not be positioned.

[0064] Referring again to Figure 4b, the eNodeB 405,406 may be capable of providing the UE 415 with access to the PDN 440 through separate uplink resource grants, which may refer to one or more component carriers. LTE, as described. Accordingly, the UE 415 may involve a carrier aggregation in dual connectivity, where one connection is to one network entity (eNodeB 405) and the other connection is to a different network entity (eNodeB 406). Using this access to the PDN 440, the UE 415 can communicate with the peer entity 455. The UE 415 can establish a split carrier that uses connections to eNodeB 405 and to eNodeB 406 to access the PDN 440 through the EPC 480 In the depicted example, the split carrier is provided in coordination with the eNodeB 405 as a MeNodeB and the eNodeB 406 as a SeNodeB. Thus, for example, eNodeBs 405 and 406 may communicate with each other over an common packet data carrier (PDCP) on MeNodeB 405. For example, the carrier(s) between UE 415 and MeNodeB 405 may have a physical layer (PHY), MAC, RLC, etc. independent of the carrier(s) between UE 415 and SeNodeB 406) and the MeNodeB 405 can aggregate communications received over the PHY, MAC, RLC, etc. layers. independent of the various carriers in the common PDCP layer.

[0065] In this example, the UE 415 can access the PDN 440 using the split carrier, which can map communications via data paths 446 and 451 to access the PDN 440. Furthermore, in this example, MeNodeB 405 may provide UE-specific upper layer functionalities to the UE 415, such as non-access stratum (NAS) functions that include NAS security, NAS mobility functions, etc. Furthermore, in this example, the SeNodeB 406 may transport the PUCCH to the SCG and provide other lower layer functionality similar to Pcell for the SCG. In this way, the UE 415 may communicate independently with MeNodeB 405 and SeNodeB 406, which may give rise to a situation in which the UE 415 is configured for half-duplex communications with one of or both the MeNodeB 405 and the SeNodeB 406, but may be perform full duplex communications with the MeNodeB 405 and SeNodeB 406 when considered together based on the separate band configurations for MeNodeB 405 and SeNodeB 406.

[0066] The MME 430 may be the control node that processes signaling between the UE 415 and the EPC 480, as described. The MME 430 can provide carrier and connection management to establish and manage split carrier connectivity. Therefore, the MME 430 may be responsible for idle mode UE paging and tracking, carrier activation and deactivation, and SGW selection for the UE 415. The MME 430 may communicate with the eNodeBs 405 and 406 via a YES ME. The MME 430 may additionally authenticate the UE 415 and deploy Non-Access Stratum (NAS) signaling with the UE 415 as described.

[0067] All user IP packets transmitted via LTE may be transferred via eNodeB 405 or eNodeB 406 to the SGW 432, which may be connected to the PDN communications port 434 via a signaling interface S5 and the MME 430 via an S11 signaling interface. In one example, as shown, the MME 430 may aggregate data received via data paths 446 and 451 based on data that is associated with the same split carrier and may provide the aggregated data to the SGW 432 for further processing.

[0068] Thus, in the present example, user plane data between the UE 415 and the EPC 480 may cross the split carrier, which may be an EPS carrier, over resources granted by one or more of the eNodeB 405 and 406. Control or signaling plane data related to the set of one or more EPS carriers may be transmitted between the LTE radio 420 of the UE 415 and the control plane data specific to the related control plane data of the eNodeB or carrier.

[0069] Although the aspects of Figure 4b have been described in relation to LTE, similar aspects in relation to aggregation and/or multiple connections can also be implemented in relation to UMTS or other similar system or wireless communications radio technologies. network.

[0070] Figure 5 is a diagram conceptually illustrating multiple connectivity carrier aggregations in accordance with an aspect of the present disclosure. A wireless communications system 500 may include a core eNodeB 505-a (MeNodeB or MeNB) that has a set or group of cells referred to as a core cell group or MCG that may be configured to serve the UE 515. The MCG may include a primary cell (PCellMCo) 510-a and one or more secondary cells 510-b (only one is shown). The wireless communications system 500 may also include a secondary eNodeB 505-b (SeNodeB or SeNB) that has a set or group of cells referred to as a secondary cell group or SCG that may be configured to serve the UE 515. SCG may include a primary cell (PCellSCG) 512-a and one or more secondary cells 512-b (only one is shown). Also shown is a UE 515 that supports carrier aggregation for multiple connectivity (e.g., dual connectivity) wireless communications. The UE 515 can communicate with the MeNodeB 505 or a related PCellMCG, via communication link 525-a and with the SeNodeB 505-b or a related PCellsco, via the communication link 525b. Additionally, the UE 515 may include a communication component 640 to perform half-duplex/full-duplex operations in multi-connectivity wireless communications and/or carrier aggregation (with one or more base stations), as described herein. .

[0071] In an example, the UE 515 may aggregate component carriers from the same eNodeB or may aggregate component carriers from positioned or non-positioned eNodeBs. In such an example, the various cells (e.g., different component carriers (CCs)) that are used can be easily coordinated due to the fact that they are handled by the same eNodeB or by eNodeBs that can communicate control information. When the UE 515, as in the example in Figure 5, performs carrier aggregation when communicating with two eNodeBs that are not co-located, then the carrier aggregation operation may be different due to various network conditions. In this case, establishing a primary cell (PCellSCO) on the secondary eNodeB 505-b may allow appropriate configurations and controls to occur on the UE 515 although the secondary eNodeB 505-b is not co-located with the primary eNodeB 505-a.

[0072] In the example of Figure 5, carrier aggregation may involve certain functionalities by the PCellMGC of the MeNodeB 505-a. For example, PCellMGC can handle certain functionalities such as a physical uplink control channel (PUCCH), a contention-based random access control channel (RACH), and semi-persistent scheduling to name a few. Carrier aggregation with dual or multiple connectivities to non-collocated eNodeBs may involve having to make some enhancements and/or modifications to the way in which carrier aggregation is otherwise performed. Some of the enhancements and/or modifications may involve having the UE 515 connected to the MeNodeB 505-a and the SeNodeB 505-b as described above. Other features may include, for example, having a timer adjustment group (TAG) comprising cells of one of the eNodeBs, having contention-based and contention-free random access (RA) allowed on the SeNodeB 505-b, procedures discontinuous reception (DRX) for the MeNodeB 505-a and the SeNodeB 505-b, cause the UE 515 to send a temporary storage status report (BSR) to the eNodeB on which the one or more bearers (e.g. , specific or split eNodeB carriers) are served, as well as allowing one or more of power height reporting (PHR), power control, semi-persistent scheduling (SPS), and logical channel prioritization in connection with the PCellSCG on secondary eNodeB 505-b. The enhancements and/or modifications described above and as others provided in the disclosure are intended for purposes of illustration and not limitation.

[0073] For carrier aggregation in dual connectivity, different functionalities can be divided between the MeNodeB 505-a and the SeNodeB 505-b. For example, different functionalities may be statically divided between the MeNodeB 505-a and the SeNodeB 505-b or dynamically divided between the MeNodeB 505-a and the SeNodeB 505-b based on one or more network parameters. In one example, the MeNodeB 505-a may perform higher layer functionality (e.g., layer above media access control (MAC)) via a PCellMGC, such as, but not limited to, functionality relative to the initial configuration , security, system information and/or radio link failure (RLF). As described in the example in Figure 5, the PCellMGC can be configured as one of the MeNodeB 505-a cells that belong to the MCG. The PCellMGC can be configured to provide lower layer functionality (e.g. MAC/PHY layer) within the MCG.

[0074] In one example, the SeNodeB 505-b may provide configuration information of lower layer functionalities (e.g., MAC/PHY layers) to the SCG. Configuration information may be provided by PCellSCG as one or more Radio Resource Control (RRC) messages, for example. The PCellSCG can be configured to have the smallest cell index (e.g., identifier or ID) among the cells in the SCG. For example, some of the functionality performed by the SeNodeB 505-b through the PCellSCG may include porting the PUCCH, configuring the cells in the SCG to follow the PCellSCG DRX configuration, configuring resources for contention-based and contention-free random access on the SeNodeB 505b, port downlink (DL) leases that have transmit power control (TPC) commands to PUCCH, estimate path loss based on PCellSCG to other cells in the SCG, provide common search space for the SCG, and provide SPS configuration information to the UE 515.

[0075] In some aspects, the PCellMGC may be configured to provide higher-level functionality than the UE 515, such as security, connection to a network, initial connection and/or radio link failure, for example. The PCellMGC can be configured to carry physical upper link control channel (PUCCH) to the cells in the MCG, to include the lowest cell index within the MCG, to allow the MCG cells to have the same discontinuous reception configuration (DRX ), to configure random access resources for one or both of contention-based and contention-free random access on the MeNodeB 505-a, to allow downlink grants to transmit power control commands (TPC) to PUCCH, to enable path loss estimation for cells in the MCG, to configure a common search space for the MeNodeB 505-a, and/or to configure semi-persistent scheduling.

[0076] In some aspects, the PCellSCG may be configured to port PUCCH to cells in the SCG, to include the lowest cell index within the SCG, to allow SCG cells to have the same DRX configuration, to configure access resources random to one or both of contention-based and contention-free random access on the SeNodeB 505-b, to allow downlink leases to transmit commands from TPC to PUCCH, to allow path loss estimation for cells in the SCG, to configure a common search space for the SeNodeB 505-b and/or to configure a semi-persistent schedule.

[0077] Returning to the example in Figure 5, the UE 515 may support physical uplink shared channel (PUSCH) and PUCCH configurations parallel to the MeNodeB 505-a and the SeNodeB 505-b. In some cases, the UE 515 may use a configuration (e.g., based on UE 515) that may be applicable to both carrier groups. These PUCCH/PUSCH settings can be provided through RRC messages, for example.

[0078] The UE 515 may also support a parallel configuration for simultaneous transmission of acknowledgment (ACK)/negative acknowledgment (NACK) and channel quality indicator (CQI) and for ACK/NACK/sound reference signal (SRS) for the MeNodeB 505-a and the SeNodeB 505-b. In some cases, the UE 515 may use a configuration (e.g., UE-based and/or MCG or SCG-based) that may be applicable to both carrier groups. These settings can be provided through RRC messages, for example.

[0079] Figure 6 is a block diagram 600 that conceptually illustrates an example of a UE 615 and components configured in accordance with an aspect of the present disclosure. Figure 7, which is described in conjunction with Figure 6 herein, illustrates an exemplary method 700 in accordance with aspects of the present disclosure. Although the operations described below in Figure 7 are presented in a particular order and/or as being performed by an exemplary component, it should be understood that the order of the actions and the components performing the actions may be varied depending on the implementation. Furthermore, it should be understood that the following actions or functions may be performed by a specially programmed processor, a processor executing specially programmed software or computer-readable media, or by any other combination of a hardware component and/or a hardware component. software that has the capacity to perform the actions or functions described.

[0080] Referring to Figure 6, a base station/an eNodeB 605-a (MeNodeB with a PCellMCG), a base station/an eNodeB 605-b (SeNodeB with a PCellSCG) and the UE 615 of diagram 600 may be one of the base stations/eNodeBs (or APs) and the UEs as described in various Figures above (e.g., Figure The MeNodeB 605-a or a PCellMCG related thereto and the UE 615 can communicate over the communication 625-a. The SeNodeB 605-b or a PCellSCG related thereto and the UE 615 may communicate over the communication link 625-b. Each of the communication links 625-a, 625-b may be an example of the communication links 125 of Figure 1 and/or may include one or more component carriers (e.g., LTE component carriers 330-1 to 330-N, 330-M to 330P, etc. in Figure 3). Furthermore, for example, the UE 615 may receive one AC band configuration for communication link 625-a (e.g., from the MeNodeB 605-a) and another AC band configuration for communication link 625-b (e.g. from SeNodeB 605-b).

[0081] In this regard, the UE 615 may include a communication component 640 to manage communications over the communication links 625-a, 625-b between UE 615 and MeNodeB 605-a and SeNodeB 605-b, respectively, in accordance with received AC band settings. For example, the CA band configurations may specify bands for each of the one or more carriers configured for each communication link 625-a, 625-b, resources over each of the bands over which the UE 615 may communicate ( e.g., with the use of one or more channels or otherwise), a subframe configuration (e.g., for time division duplexing (TDD) communications), subframe steering, channel state information handling ( CSI), PHICH availability handling, etc. to the related eNodeBs and/or MCG, SCG, etc. In an example, the communication component 640 may indicate one or more UE capabilities 615 to the MeNodeB 605-a and/or SeNodeB 605-b, from which the AC band configuration may be generated. For example, the one or more capabilities of the UE 615 may refer to the possibility of the UE 615 communicating using half duplexing and/or full duplexing, transmission power capabilities, etc.

[0082] Referring to Figure 7, method 700 includes, in Block 710, communicating with a first cell served by a first access point over a first connection. For example, the UE 615 (Figure 6) may include communication component 640 for communicating with the first cell (e.g., an MCG) served by the first access point (e.g., the MeNodeB 605-a (and/or other eNodeBs)) over the first connection (e.g., communication link 625-a and/or one or more component carriers associated therewith). In one example, the communication component 640 may include a MeNodeB connection configuration component 650 may receive first configuration information for the communication link 625-a, such as full duplex/half duplex configuration information that indicates the possibility of performing half-duplexing or full-duplexing operations, a CA band configuration that indicates over which component carriers UE 615 can communicate with MeNodeB 605-a, which subframes during which the UE 615 can expect to receive or transmit communications to from/to the MeNodeB 605-a, etc., and/or additional configuration information described above. The communication component 640 may communicate with MeNodeB 605-a or a related PCellMCG, over the communication link 625-a according to the first configuration information. This may include the communication component 640 communicating with the MeNodeB 605-a based on the AC band configuration, based on one or more capabilities of the UE 615 (e.g., determined the AC band configuration or other mode) and/or similar.

[0083] Method 700 also includes, in Block 712, communicating with a second cell served by a second access point over a second connection. This can allow multi-connectivity wireless communications to communicate with the first and second cells. For example, the communication component 640 may communicate with the second cell (e.g., an SCG) served by the second access point (e.g., the SeNodeB 605-b and/or other eNodeBs) over the second connection (e.g., communication link 625-b and/or one or more component carriers associated therewith). In one example, the communication component 640 may include a SeNodeB connection configuration component 655 may receive first configuration information for the communication link 625-a, such as full duplex/half duplex configuration information that indicates the possibility of performing half-duplexing or full-duplexing operations, a CA band configuration that indicates over which component carriers the UE 615 can communicate with seNodeB 605-b, which subframes during which the UE 615 can wait to receive or transmit communications from/to the SeNodeB 605-b, etc., and/or additional configuration information as described above. The communication component 640 may communicate with SeNodeB 605-b or a related PCellSCG over the communication link 625-b in accordance with the second configuration information. This may include the communication component 640 that communicates with the MeNodeB 605-a based on the AC band configuration, based on one or more capabilities of the UE 615, etc., as described above.

[0084] Method 700 additionally includes, in Block 714, determining whether to perform a half duplex operation or a full duplex operation for communicating with the first cell served by the first access point over the first connection. The UE 615 may additionally include a half-duplex/full-duplex operation component 660 that may determine whether to perform the half-duplex operation or the full-duplex operation for communication with the first cell (e.g., the MCG ) served by the first access point (e.g., MeNodeB 605-a) over the first connection (e.g., communication link 625-a and/or one or more component carriers associated therewith), which may be based on the least in part the received full/half duplex configuration information, AC band configuration received from the MeNodeB 605-a and/or SeNodeB 605b, one or more capabilities of UE 615 and/or the like. For example, the half-duplex/full-duplex operation component 660 may determine whether to perform half-duplex or full-duplex operations over the communication link 625-a and/or 625-b based on first and second configuration information. configuration information respectively.

[0085] Method 700 additionally includes, in Block 716, determining whether to perform a half duplex operation or a full duplex operation for communicating with the second cell served by the second access point over the second connection. Thereby, the half-duplex/full-duplex operation component 660 may also determine whether to perform the half-duplex operation or the full-duplex operation for communication with the second cell (e.g., the SCG) served by the second peer. (e.g., SeNodeB 605-b) over the second connection (e.g., communication link 625-b or one or more component carriers associated therewith), which may be based at least in part on the configuration of AC band received from the MeNodeB 605-a and/or SeNodeB 605-b, one or more UE 615 capabilities and/or the like. In this sense, the communication component 640 may communicate over the communication link 625-a and/or communication link 625-b in dual connectivity by performing half-duplex or full-duplex operations, depending on the respective half-duplex configuration information. duplexing/full duplexing, AC band configurations, UE 615 capabilities and/or similar.

[0086] Furthermore, method 700 may optionally include, in Block 718, communicating with the first cell using the half-duplex or full-duplex operation and communicating with the second cell using the half-duplex or full-duplex operation. complete. The communication component 640 may communicate with the first cell (e.g., the MCG) using full duplex or half duplex operation, which may be based on the half duplex/full duplex operation component 660 that determines the possibility of performing half duplexing or full duplexing with the first cell. Additionally, for example, the communication component 640 may communicate with the second cell (e.g., the SCG) using full duplex or half duplex operation, which may be based on the half duplex/duplex operation component. complete 660 which determines the possibility of performing half duplexing or full duplexing operation with the second cell. For example, communication using a half-duplex operation may include transmitting communications to the MeNodeB 605-a or SeNodeB 605-b or receiving communications from the MeNodeB 605-a or SeNodeB 605-b based on a subframe configuration ( e.g., in TDD) or based on other information corresponding to an AC band configuration, UE 615 capability, etc.

[0087] In an example, communicating with the first cell and the second cell in Block 718 may optionally include, in Block 720, communicating with one of the first cell over the first connection or the second cell over the second connection to receiving communications in a full duplex operation and communicating with the other of the first cell over the first connection and the second cell over the second connection to transmit communications in the full duplex operation. The half-duplex/full-duplex operation component 660 may optionally include a multiple connection component 662 that may communicate with the first cell (e.g., the MCG) over the first connection (e.g., communication link 625-a ) or the second cell (e.g., SCG) over the second connection (e.g., 625-b communication link) to receive communications in full duplex operation and communicate with the other of the first cell over the first connection or the second cell over the second connection to transmit communications in full duplex operation. Thus, for example, where a configuration (e.g., an AC band configuration for communication link 625-a, 625-b, UE capabilities 615, etc.) allows half-duplex operations with MeNodeB 605-a or SeNodeB 605-b, a component employing optional multiple connection 662 may utilize both communication links 625-a and 625-b to perform full duplex operation in multiple connectivity wireless communications. In particular, for example, the multiple connection component 662 may instruct the communication component 640 to transmit communications over one of the communication links 625-a or 625-b while receiving communications over the other of the communication links 625-a or 625-b (e.g., in a certain time interval or other mode). It should be appreciated that full duplexing operations may be requested from a higher layer of the UE 615 (e.g., an application running the UE 615, desired to provide a quality of service specified by a UE 615 carrier, and/or the like). ) and component employing multiple connection 662 may accordingly utilize multiple communication links 625-a, 625-b to provide full duplexing operations to satisfy the request. In another example, the half-duplex/full-duplex operating component 660 may utilize multiple communication links 625-a, 625-b to perform full-duplex operations based on determining that the component employing multiple connection 662 has ability to use multiple connections (e.g., based on AC band configuration, a band-related resource configuration, and/or the like).

[0088] In another example, determining the possibility of performing the half-duplexing or full-duplexing operation with one of the cells may be based on a transmission power for communication with the cells. For example, if the transmit power of the UE 615 is low enough, a dedicated radio frequency (RF) filter may be required to enable full duplex operation, and then full duplex operation may be enabled in any case when the transmit power is less than the limit. Thus, in one example, determining the possibility of performing half-duplexing or full-duplexing operation with the second cell in Block 716 may optionally include, in Block 722, determining the possibility of a transmit power for the duplexing operation. complete be less than a threshold. For example, the half-duplex/full-duplex operation component 660 may optionally include a transmit power determining component 664 that may determine a transmit power for communicating with the SeNodeB 605-b over the communication link 625 -b and the half duplex/full duplex operation component 660 may determine whether the transmit power for full duplex operation is less than a threshold. In this case, the half duplex/full duplex operation component 660 may determine to perform full duplex operations over communication link 625-b when the power is less than the threshold. In one example, the transmit power determination component 664 may determine transmit power based on a power class of the SeNodeB 605-b (e.g., based on determining that the SeNodeB 605-b is a small cell ), based on a transmit power configured for the UE 615 by the SeNodeB 605-b, based on radio conditions or a detected proximity to the SeNodeB 605-b, and/or the like. For example, where the SeNodeB 605-b is a small cell, the UE 615 may suppress a transmit signal to be below the threshold so that a dedicated RF filter is not required to allow full duplex operation over the transmission link. 625-b communication while the transmission power is low. In one example, the limit might be 10 decibels. In this way, the small cell can receive the transmission at low power. In this sense, where half duplex is configured with the MeNodeB 605-a over the communication link 625-a, the half duplex/full duplex operation component 660 can configure full duplex operations with SeNodeB 605-b over the link of communication 625-b based on determining the transmission power for the UE 615 less than the threshold power. It should be appreciated that the threshold and/or full duplex setting based on the threshold may be configured by the MeNodeB 605-a and/or SeNodeB 605b, so that the communication component 640 can receive a setting and determine whether to perform the duplex operation. Full duplexing additionally based on configuration.

[0089] It should be appreciated that in scenarios without dual connectivity, the SeNodeB 605-b may be equal to or part of the MeNodeB 605-a such as to provide a second cell (e.g., a SCell) with which the UE 615 connects. communicates over the 625-b communication link. For example, where the second cell is CA supported while also enabling PUCCH communications (e.g., based on a received CA band configuration for communication with a first cell and the second cell over the CA), full duplexing or half duplexing operations may be determined on one or more carriers or groups of carriers configured for each of the first and second cells individually as described above with respect to the cells provided by the MeNodeB 605-a and SeNodeB 605-b. Performing full duplexing or half duplexing operations may be based on the AC band configuration received for the first and second cells, UE 615 capabilities, and/or the like. Furthermore, in this example, the component employing multiple connection 662 can take advantage of multiple groups of carriers to perform full duplexing operations in which each of the (or at least one or more) groups supports half duplexing operations, as described.
