Technical Field

[0004] Aspects of the present disclosure relate to wireless communication, and in particular, to techniques for mobility-aware access control. When a communication component / device is initially communicating and moving around or within a communication network, some aspects and techniques can be used to enhance mobility-based communication, initial network access, cell selection (reselection), and / or handover procedures. Background Art

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasting, etc. These wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access systems include the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) system, the Advanced LTE (LTE-A) system, the Code Division Multiple Access (CDMA) system, the Time Division Multiple Access (TDMA) system, the Frequency Division Multiple Access (FDMA) system, the Orthogonal Frequency Division Multiple Access (OFDMA) system, the Single Carrier Frequency Division Multiple Access (SC-FDMA) system, and the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, to name just a few examples.

[0006] These multiple access techniques have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. New radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is an enhanced set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, leveraging new spectrum, and better integrating with other open standards that use OFDMA with cyclic prefix (CP) on the downlink (DL) and uplink (UL). To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0007] As the demand for mobile broadband access continues to grow, there is a need for further improvement in NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access techniques and the telecommunication standards that employ these techniques. Summary of the Invention

[0008] The systems, methods, and devices of the present disclosure each have several aspects, none of which alone is responsible for its desirable attributes. Without limiting the scope of the present disclosure as expressed by the appended claims, some features will now be briefly discussed. After considering this discussion, and particularly after reading the section entitled "Detailed Description," it will be understood how the features of the present disclosure provide advantages including improved mobility-aware access control.

[0009] Each aspect or embodiment includes a variety of mobility-aware features. In some scenarios, these features can be used in combination with and / or for communication in a variety of network arrangements. For example, a radio access network may include a wireless backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one base station acts as an anchor base station (also referred to as an IAB donor), which communicates with the core network (via a wired backhaul link). The IAB network may include one or more non-anchor base stations (also referred to as IAB nodes), which can communicate directly or indirectly (e.g., via one or more other non-anchor base stations) with the anchor base station via one or more wireless backhaul links to form a backhaul path to the core network.

[0010] According to some aspects, IAB networks and communication devices generally may include a variety of mobility-related features. For example, in a typical IAB network, IAB nodes (e.g., non-anchor base stations) are stationary (i.e., not moving). In contrast, in a mobile IAB network, some IAB nodes may have the ability to move (i.e., they can move around in the IAB network). Such IAB nodes may be referred to as mobile IAB nodes. For example, a mobile IAB node may be installed on a vehicle (e.g., a bus, a train, a taxi) and / or many other items capable of movement. In a mobile IAB network, there may be a mix of stationary IAB nodes and mobile IAB nodes.

[0011] According to some aspects, components or nodes in a network (e.g., an IAB network) may have a variety of operational states (e.g., mobility states). The mobility state of a given IAB node can affect the operation of a mobile IAB network. For example, the execution of several IAB network-related operations may depend on the mobility state of a mobile IAB node. Such IAB network-related operations may include, for example, IAB topology and resource management, local scheduling, beam management, beam tracking, synchronization tracking, positioning, quality of service (QoS) type support identification, access, and paging, etc. Thus, knowledge of the mobility state of a given IAB node may be desirable to enable efficient and acceptable performance of a mobile IAB network.

The method generally includes: obtaining at least one of first mobility state information corresponding to a first cell, second mobility state information corresponding to a second cell, or third mobility state information corresponding to a wireless device in the network. The method may further include: receiving a measurement report from a UE. In some cases, the measurement report may include measurement information associated with the second cell. The method may further include: determining whether to initiate a handover procedure for handing over the wireless device from the first cell to the second cell. In some cases, determining whether to initiate the handover procedure may be at least partially based on at least one of the first mobility state information, the second mobility state information, or the third mobility state information. Additionally, in some cases, the method may further include: taking one or more actions based on the determination.

[0055] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for mobility-aware access control. For example, the mobility state of an integrated access and backhaul (IAB) node can affect the operation of a mobile IAB network. For example, the execution of several IAB network-related operations can depend on the mobility state of a mobile IAB node. Such IAB network-related operations can include, for example, initial cell access, cell selection / reselection, and cell handover. Thus, given the mobility state of a given mobile IAB node / cell, the mobile IAB node may or may not be the best choice for serving a user equipment (UE) or a mobile terminal component (MT). Thus, knowledge of the mobility state of a given IAB node may be desirable to facilitate the cell selection / access / handover operations described above to achieve efficient and acceptable performance of a mobile IAB network.

[0056] The following description provides examples of mobility-aware access control in a communication system and is not intended to limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of the present disclosure. Various examples may appropriately omit, substitute, or add various procedures or components.

Also, features described with reference to some examples may be combined in some other examples. For example, any number of aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functionality, or a combination of structures and functionality that are complementary to or additional to the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of the claims. The term "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" should not necessarily be construed as superior to or better than other aspects.

[0057] In general, any number of wireless networks may be deployed in a given geographical area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, etc. A frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, a subband, etc. Each frequency may support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, a 5G NR RAT network may be deployed.

[0058] Figure 1An example wireless communication network 100 in which aspects of the present disclosure may be implemented is described. For example, the wireless communication network 100 may be an NR system (e.g., a 5G NR network).

[0059] As Figure 1 described, the wireless communication network 100 may include several base stations (BSs) 110a - z (each also individually referred to herein as BS 110 or collectively as BS 110) and other network entities. The BS 110 may provide communication coverage for a particular geographical area (sometimes referred to as a “cell”), which may be stationary or may move according to the location of the mobile BS 110. In some examples, the BSs 110 may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless communication network 100 using any suitable transport network via various types of backhaul interfaces (e.g., direct physical connections, wireless connections, virtual networks, etc.). In Figure 1 the example shown, BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more cells. The BS 110 communicates with user equipment (UEs) 120a - y (each also individually referred to herein as UE 120 or collectively as UE 120) in the wireless communication network 100. The UEs 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile.

[0060] According to certain aspects, the BS 110 and the UE 120 may be configured for mobility - aware access control as described herein. As Figure 1 shown, BS 110a includes a mobility - aware access control module 112. According to aspects of the present disclosure, the mobility - aware access control module 112 may be configured to perform Figures 5 - 15 the operations for mobility - aware access control as described in one or more of Figure 1 shown, UE 120a includes a mobility - aware access control module 122. According to aspects of the present disclosure, the mobility - aware access control module 122 may be configured to perform Figures 5 - 15 the operations for mobility - aware access control as described in one or more of

[0061] The wireless communication network 100 may also include a relay station (e.g., relay station 110r) (also referred to as a relay, etc.), which receives transmissions of data and / or other information from an upstream station (e.g., BS110a or UE 120r) and sends transmissions of data and / or other information to a downstream station (e.g., UE 120 or BS110), or relays transmissions between the UEs 120 to facilitate communication between the devices.

[0062] The network controller 130 may be coupled to a set of BS110s and provide coordination and control for these BS110s. The network controller 130 may communicate with the BS110s via a backhaul. The BS110s may also communicate with each other via a wireless or wired backhaul (e.g., directly or indirectly).

[0063] Figure 2 Examples of components of BS110a and UE 120a that may be used to implement aspects of the present disclosure are illustrated (e.g., in the Figure 1 wireless communication network 100).

[0064] At BS110a, the transmit processor 220 may receive data from the data source 212 and control information from the controller / processor 240. The control information may be used for the physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical hybrid ARQ indicator channel (PHICH), physical downlink control channel (PDCCH), group common PDCCH (GC PDCCH), etc. The data may be used for the physical downlink shared channel (PDSCH), etc. The processor 220 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols (such as for the primary synchronization signal (PSS), secondary synchronization signal (SSS), and cell-specific reference signal (CRS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, and / or reference symbols, if applicable, and may provide the output symbol streams to the modulators (MOD) in the transceivers 232a - 232t. Each modulator in the transceivers 232a - 232t may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators in the transceivers 232a - 232t may be transmitted via the antennas 234a - 234t, respectively.

[0065] At UE 120a, antennas 252a - 252r may receive downlink signals from BS110a and may provide the received signals to demodulators (DEMOD) in transceivers 254a - 254r, respectively. Each demodulator in each transceiver may condition (e.g., filter, amplify, down-convert, and digitize) its respective received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain the received symbols from all demodulators in transceivers 254a - 254r, perform MIMO detection on these received symbols when applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, de-interleave, and decode) these detected symbols, provide the decoded data for UE 120a to data sink 260, and provide the decoded control information to controller / processor 280.

[0066] On the uplink, at UE 120a, a transmit processor 264 may receive and process data from a data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from controller / processor 280 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 264 may also generate reference symbols for reference signals (e.g., sounding reference signals (SRS)). The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 when applicable, further processed by demodulators in transceivers 254a - 254r (e.g., for SC-FDM, etc.), and transmitted to BS110a. At BS110a, the uplink signal from UE 120a may be received by antennas 234, processed by modulators in transceivers 232a - 232t, detected by a MIMO detector 236 when applicable, and further processed by a receive processor 238 to obtain the decoded data and control information transmitted by UE 120a. The receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240.

[0067] Memories 242 and 282 may store data and program codes for BS110a and UE 120a, respectively. A scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.

[0068] The controller / processor 280 and / or other processors and modules at UE 120a may execute or direct the execution of processes for the techniques described herein. For example, as Figure 2As shown in FIG. , the controller / processor 240 of BS110a includes a mobility-aware access control module 241; in accordance with aspects described herein, the mobility-aware access control module 241 may be configured to perform Figures 5 - 15 the operations for mobility-aware access control as recited in one or more of Figure 2 As shown in FIG. , the controller / processor 280 of UE 120a includes a mobility-aware access control module manager 281; in accordance with aspects described herein, the mobility-aware access control module manager 281 may be configured to perform Figures 5 - 15 the operations for mobility-aware access control as recited in one or more of

[0069] Figure 3 Although shown at the controller / processor, other components of UE 120a and BS110a may also be used to perform the operations described herein.

[0070] As shown by reference numeral 305, a conventional (e.g., 3G, 4G, LTE) radio access network may include a plurality of base stations 310 (e.g., access nodes (AN)), where each base station 310 communicates with a core network via a wired backhaul link 315 (such as a fiber connection). The base station 310 may communicate with a UE 320 via an access link 325, which may be a wireless link. In some aspects, Figure 3 the base station 310 shown in Figure 1 may correspond to the base station 110 shown in Figure 3 Similarly, Figure 1 the UE 320 shown in

[0071] As shown by reference numeral 330, a radio access network may include a wireless backhaul network. In some aspects or scenarios, the wireless backhaul network may sometimes be referred to as an integrated access and backhaul (IAB) network. The IAB network may include a plurality of base stations, and sometimes these base stations may be of different types or have different operating characteristics. For example, in some aspects, the IAB network may have at least one base station that is an anchor base station 335. The anchor base station may communicate with a core network via a wired backhaul link 340 (such as a fiber connection). The anchor base station 335 may also be referred to as an IAB donor. The anchor base station may be configured to communicate with other types of base stations or other communication devices (e.g., in a radio network or an IAB network).

[0072] The IAB network may also include one or more non-anchor base stations 345. The non-anchor base stations may be referred to as relay base stations or IAB nodes. The non-anchor base stations 345 may communicate with the anchor base station 335 directly or indirectly (e.g., via one or more other non-anchor base stations 345) via one or more backhaul links 350 to form a backhaul path to the core network for carrying backhaul traffic. The backhaul link 350 may be a wireless link. The anchor base station(s) 335 or the non-anchor base station(s) 345 may communicate with one or more UEs 355 via an access link 360, which may be a wireless link for carrying access traffic. In some aspects, Figure 3 the anchor base station 335 or non-anchor base station 345 shown in Figure 1 may correspond to the base station 110 shown in Figure 3 Similarly, the UE 355 shown in Figure 1 may correspond to the UE 120 shown in

[0073] As shown by reference numeral 365, in some aspects, the radio access network including the IAB network may utilize various spectrum types. For example, the IAB network may utilize various different radio frequency bands. In some specific examples and according to some aspects, millimeter wave technology or directional communication may be used (e.g., beamforming, precoding) for communication between base stations or UEs (e.g., between two base stations, between two UEs, or between a base station and a UE). In additional or alternative aspects or examples, the wireless backhaul link 370 between base stations may use millimeter wave to carry information, or may use beamforming, precoding to point to the target base station. Similarly, the wireless access link 375 between the UE and the base station may use millimeter wave, or may point to the target radio node (e.g., UE or base station). In this way, inter-link interference may be reduced.

[0074] In some aspects, the IAB network may support multi-hop networks or multi-hop wireless backhaul. Additionally or alternatively, each node of the IAB network may use the same radio access technology (e.g., 5G / NR). Additionally or alternatively, the nodes of the IAB network may share resources for access links and backhaul links, such as time resources, frequency resources, and space resources. Furthermore, various architectures of IAB nodes or IAB donors may be supported.

[0075] In some aspects, the IAB donor may include a central unit (CU) that configures the IAB nodes accessing the core network via the IAB donor; and may include a distributed unit (DU) that schedules and communicates with the sub-nodes of the IAB donor.

[0076] In some aspects, the IAB node may include a Mobile Termination (MT) component that is scheduled by and communicates with the DU of the parent node; and may include a DU that schedules and communicates with the child nodes of the IAB node. The DU of the IAB node may perform the functions described in connection with the base station 110 for the IAB node, and the MT of the IAB node may perform the functions described in connection with the UE 120 for the IAB node.

[0077] Figure 4 is a diagram illustrating an example of an IAB network architecture in accordance with various aspects of the present disclosure. As Figure 4 shown, the IAB network may include an IAB donor 405 that is connected to the core network via a wired connection (e.g., as a wired optical fiber). For example, the Ng interface of the IAB donor 405 may be terminated at the core network. Additionally or alternatively, the IAB donor 405 may be connected to one or more devices of the core network that provide core access and mobility management functions (AMF). In some aspects, the IAB donor 405 may include a base station 110, such as an anchor base station as described above in connection with Figure 3 As shown, the IAB donor 405 may include a CU that may perform an ANC function or an AMF function. The CU may configure the DU of the IAB donor 405, or may configure one or more IAB nodes 410 (e.g., the MT or DU of the IAB node 410) connected to the core network via the IAB donor 405. Thus, the CU of the IAB donor 405 may control or configure the entire IAB network connected to the core network via the IAB donor 405, such as by using control messages or configuration messages (e.g., Radio Resource Control (RRC) configuration messages, F1 Application Protocol (F1AP) messages).

[0078] As described above, the IAB network may include IAB nodes 410 (shown as IAB nodes 1 to 4) connected to the core network via the IAB donor 405. As shown, the IAB node 410 may include an MT and may include a DU. The MT of the IAB node 410 (e.g., a child node) may be controlled or scheduled by another IAB node 410 (e.g., a parent node) or by the IAB donor 405. The DU of the IAB node 410 (e.g., a parent node) may control or schedule other IAB nodes (e.g., the child nodes of the parent node) or the UE 120. Thus, the DU may be referred to as a scheduling node or a scheduling component, and the MT may be referred to as a scheduled node or a scheduled component. In some aspects, the IAB donor 405 may include a DU and not include an MT. That is, the IAB donor 405 may configure, control, or schedule the communication of the IAB node 410 or the UE 120. The UE 120 may include only an MT and not include a DU. That is, the communication of the UE 120 may be controlled or scheduled by the IAB donor 405 or the IAB node 410 (e.g., the parent node of the UE 120).

[0079] According to some aspects, certain nodes may be configured to participate in a control / scheduling process. For example, in some aspects, when a first node controls or schedules communications for a second node (e.g., when the first node provides a DU function for the MT of the second node), the first node may be referred to as the parent node of the second node, and the second node may be referred to as the child node of the first node. The child node of the second node may be referred to as the grandchild node of the first node. Thus, the DU of the parent node may control or schedule communications for the child nodes of that parent node. The parent node may be an IAB donor 405 or an IAB node 410, and the child node may be an IAB node 410 or a UE 120. The communications of the MT of the child node may be controlled or scheduled by the parent node of that child node.

[0080] As Figure 4 further shown, the link between the UE 120 and the IAB donor 405 or between the UE 120 and the IAB node 410 may be referred to as an access link 415. Each access link 415 may be a radio access link that provides radio access to the core network to the UE 120 via the IAB donor 405 and potentially via one or more IAB nodes 410.

[0081] As Figure 4 further shown, the link between the IAB donor 405 and the IAB node 410 or between two IAB nodes 410 may be referred to as a backhaul link 420. Each backhaul link 420 may be a radio access link that provides radio access to the core network to the IAB node 410 via the IAB donor 405 and potentially via one or more other intermediate IAB nodes 410. In some aspects, the backhaul link 420 may be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, if the primary backhaul link fails, becomes congested, or becomes overloaded, the secondary backhaul link may be used. In an IAB network, the physical resources (e.g., time resources, frequency resources, spatial resources) for wireless communication may be shared between the access link 415 and the backhaul link 420.

[0082] As described above, in a typical IAB network, IAB nodes (e.g., non-anchor base stations) are stationary (i.e., not moving). In contrast, in a mobile IAB network, some IAB nodes may have mobility (i.e., can move around in the IAB network). Such IAB nodes may be referred to as mobile IAB nodes. For example, an IAB node may be installed on a vehicle (e.g., a bus, a train, a taxi). In a mobile IAB network, there may be a mix of stationary IAB nodes and mobile IAB nodes. In some cases, mobile IAB nodes may be constrained to be "leaf" nodes in the mobile IAB network. That is, only mobile IAB nodes are allowed as the last-hop IAB nodes, and only child access UEs are connected to the mobile IAB nodes. In some other cases, it may also be allowed for a mobile IAB node to have another IAB node as a child node.

[0083] In some examples, a mobile IAB node may provide a cell site with independent movement. In such cases, a moving cell site (e.g., a vehicle such as a bus, a train, a taxi) is available for the IAB node to serve surrounding UEs (e.g., within an urban area). Here, the mobile IAB node can move relatively randomly at a relatively low speed (e.g., urban speed) and over a relatively large distance. In this case, the mobility of a given UE (not carried with the vehicle) is independent of the mobility of the IAB node (i.e., the movement of the UE cannot be predicted based on the movement of the mobile IAB node), but can also be at a relatively low speed (similar to the speed of the mobile IAB node).

[0084] In some other examples, a mobile IAB node may provide a cell site with joint movement (e.g., a high-speed train). In such cases, the mobile IAB node may be installed on the moving cell site (e.g., on top of a high-speed train) to serve UEs above or within the moving cell site (e.g., UEs inside the high-speed train). Here, the mobility of the mobile IAB node can be predictable at a relatively high speed and over a large distance. In this use case, UEs above or within the moving cell site move jointly with the mobile IAB node (i.e., the movement of the UE can be predicted based on the movement of the mobile IAB node).

[0085] In some other examples, for instance, when a loose group of UEs move together roughly, a mobile IAB node can facilitate a platoon. In such a case, a single IAB node can provide network connectivity for nearby UEs. For example, a mobile IAB node installed on a first vehicle traveling on a highway can provide network connectivity for the UEs in the first vehicle and the UEs in other vehicles traveling in the same direction and at a similar speed on the same highway. In such a case, the mobile IAB node is connected to the network, while the other vehicles can be equipped with corresponding sub-nodes. Here, the mobile IAB node moves with relatively constant speed and has local predictability over a relatively large distance. Moreover, these UEs move jointly with the mobile IAB node.

[0086] The mobility state of a communication device or node (e.g., an IAB node) can be defined by several characteristics. Generally speaking, the mobility state can refer to the mobility class, degree of movement, and / or movement ability of the node. The mobility state of the node can be static (e.g., unchanging) or dynamic (e.g., changing over time). The mobility state can depend on other factors such that it indicates the relative state with respect to other network nodes.

[0087] The mobility state can be based on one or more characteristics on demand or according to design / operation principles. The first characteristic can include the mobility level (e.g., stationary, low-speed mobility, medium-speed mobility, high-speed mobility). The mobility level can generally reflect the speed at a point in time, speed range, running average historical mobility / speed pattern, or some other characterization of the general movement ability. The second characteristic can include the change or transition from one mobility state to another (e.g., the mobility state of an IAB node can change or transition over time). For example, a mobile IAB node can transition (e.g., from low-speed mobility) to stationary, or can transition from one mobility class to another (e.g., from medium-speed mobility to high-speed mobility). In some instances, a timer can be associated with such a transition (e.g., an IAB node can transition from one state to another within the indicated time window). The mobility state characteristics can generally also be shared by or among devices for enhanced network operation (e.g., using various signals / messages on various interfaces).

[0088] In some cases, the mobility state of a given IAB node can affect the operation of a mobile IAB network. For example, the execution of several IAB network-related operations can depend on the mobility state of a mobile IAB node. Such IAB network-related operations can include, for example, initial cell access, cell selection / reselection, and cell handover. For example, given the mobility state of a given mobile IAB node / cell, the mobile IAB node may or may not be the best choice for the serving cell of a user equipment (UE) or a mobile terminal component (MT). For example, serving cell selection can generally be based on signal quality measurements, which may be affected by mobility. Thus, at a first moment, a mobile IAB node may have good signal quality, resulting in the UE / MT selecting the mobile IAB to camp on. However, given the mobility of the given mobile IAB node, the IAB node may have poor signal quality at a second moment shortly after the first moment. Thus, in this case, the mobile IAB node may not be the best choice as the serving cell for the UE / MT. Accordingly, knowledge of the mobility state of a given IAB node may be desirable to facilitate the cell selection / access / handover operations described above to achieve efficient and acceptable performance of a mobile IAB network.

[0089] Example Mobility-Aware Access Control

[0090] Aspects of the present disclosure provide techniques for mobility-aware access control. For example, as mentioned above, in some cases, it may be desirable to consider the mobility state information of an IAB node in initial access, cell selection / reselection, and handover procedures to avoid scenarios where the IAB node may not be suitable as a serving cell due to the mobility of the IAB node. However, depending on whether (and where) the required mobility state information is available, there can be different options for implementing mobility-aware access control as described herein.

[0091] For example, the first option may relate to a centralized solution implemented by a control unit (CU) of a network node, such as an IAB node (e.g., IAB donor 405). According to this option, the network node may control the cell selection (reselection) and / or handover of a wireless device based on mobility state information, which may be transparent to the wireless device. For example, a wireless device (e.g., UE 120 and / or MT of IAB node 410) may follow a typical cell selection (reselection) procedure based on power / quality to select a target cell (e.g., IAB node 410) to camp on. However, in some cases, the target cell may not be a suitable serving cell for the wireless device due to the mobility of the target cell (which the UE may not be aware of) (e.g., the target cell is moving at a high speed in a different direction from the wireless device, etc.). Thus, in this case, when the wireless device selects a target cell that may not be suitable for the wireless device (e.g., due to the mobility state of the target cell), the network node may instruct the wireless device to hand over to a more suitable cell. Similarly, for a connected wireless device, the target cell to hand over to may be selected based on the mobility state associated with the target cell.

[0092] Figure 5 is a flowchart illustrating an example operation 500 for wireless communication in a network according to certain aspects of the present disclosure. Operation 500 may be performed, for example, by a control unit (CU) in an IAB node (e.g., IAB donor 405). Operation 500 may be implemented as a software component executed and run on one or more processors (e.g., Figure 2 controller / processor 240). Additionally, signal transmission and reception performed by the network node in operation 500 may be implemented, for example, by one or more antennas (e.g., Figure 2 antenna 234). In some aspects, signal transmission and / or reception performed by the network may be implemented via a bus interface of one or more processors (e.g., controller / processor 240) that obtain and / or output signals.

[0093] Operation 500 may begin at 505 by obtaining at least one of first mobility state information corresponding to a first cell in the network, second mobility state information corresponding to a second cell in the network, or third mobility state information corresponding to a wireless device in the network.

[0094] At 510, the network node receives a measurement report from the wireless device, where the measurement report includes measurement information associated with the second cell.

[0095] At 515, the network node determines whether to initiate a handover procedure for handing over the wireless device from a first cell to a second cell based at least in part on at least one of first mobility state information, second mobility state information, or third mobility state information.

[0096] At 520, the network node takes one or more actions based on the determination.

[0097] As mentioned above, under a centralized approach for mobility-aware access control, a network node may control cell selection (reselection) and / or handover of a wireless device based on mobility state information.

[0098] Figure 6 Detailed call flow diagrams illustrating centralized mobility-aware access control techniques in accordance with certain aspects presented herein. Although the call flows or operation descriptions herein may be described as certain actions as steps, the described actions or steps may be preferred in various arrangements or orders. By providing an example logical description, those skilled in the art will understand that various permutations are achievable and possible.

[0099] For example, as Figure 6 illustrated, at steps 1a and 1b, a network node 602 (such as a CU which may be part of a first cell) may obtain first mobility state information corresponding to a first cell 604 and second mobility state information corresponding to a second cell 606. In some cases, obtaining the first mobility state information may include inferring the first mobility state information based at least in part on prior measurement information or prior location information associated with the first cell 604. Similarly, in some cases, obtaining the second mobility state information may include inferring the second mobility state information based at least in part on prior measurement information or prior location information associated with the second cell 606. For example, in some cases, based on prior measurements and / or location information of the first cell 604 and / or the second cell 606, the network node 602 may be able to infer whether the first cell 604 and / or the second cell 606 is relatively static with respect to a wireless device (such as a UE / MT 608). For example, in some cases, the network node 602 may be able to infer whether the first cell 604 and / or the second cell 606 is moving in the same direction as the UE / MT 608 based on prior measurement information and / or location information of the first cell 604 and / or the second cell 606. In some cases, the network node 602 may receive an explicit indication from the first cell 604 and / or the second cell 606 indicating the first mobility state information and / or the second mobility state information.

[0100] Depending on various aspects, the mobility state information may provide an indication of a mobility level corresponding to a wireless device (e.g., the first cell 604, the second cell 606, or the UE / MT 608) from which the mobility state information is received. For example, the mobility level may include one of stationary mobility, low-speed mobility, medium-speed mobility, or high-speed mobility. Additionally, in some cases, the mobility state information may provide an indication of a change or transition from one mobility state to another mobility state corresponding to a wireless device (e.g., the first cell 604, the second cell 606, or the UE / MT 608) from which the mobility state information is received. For example, in a certain case, the indication of the change or transition may indicate that the first cell 604 is transitioning from high-speed mobility to stationary mobility, and so on.

[0101] In step 2, the UE / MT 608 may perform an access procedure and establish a connection with the first cell 604.

[0102] After that, in step 3, the network node 602 may obtain third mobility state information corresponding to the UE / MT 608. In some cases, the network node 602 may receive signaling from the UE / MT 608 indicating the third mobility state information corresponding to the UE / MT 608. In other cases, the network node 602 may obtain the third mobility state information by inferring the third mobility state information at least partially based on prior measurement information or prior location information associated with the UE / MT 608 (e.g., similar to the inference described above for the first cell 604 / second cell 606).

[0103] In step 4, while camped on the first cell 604, the UE / MT 608 may enter the range of an adjacent cell (such as the second cell 606) and perform measurements on one or more signals (e.g., reference signals) received from the second cell 606.

[0104] In step 5, the network node 602 may receive a measurement report from the UE / MT 608, the measurement report including measurement information associated with the second cell 606. For example, in some cases, the measurement report may include measurement information obtained based on the one or more signals received from the second cell 606 at the UE / MT 608.

[0105] In step 6, network node 602 determines whether to initiate a handover procedure for handing over UE / MT 608 from the first cell 604 to the second cell 606, at least in part based on at least one of the first mobility state information, the second mobility state information, or the third mobility state information. In some cases, determining whether to initiate the handover procedure may include determining that the first cell 604 is not suitable for UE / MT 608 based on at least one of the first mobility state information or the third mobility state information. For example, in some cases, the network node may determine that the first cell 604 may not be suitable as the serving cell for UE / MT 608 due to the mobility of the first cell 604 or UE / MT 608 (e.g., the first cell 604 and UE / MT 608 are moving in different directions, etc.).

[0106] Accordingly, in step 7, based on the determination in step 6, network node 602 may take one or more actions. For example, in some cases, taking the one or more actions may include determining to initiate a handover procedure for handing over UE / MT 608 from the first cell 604 to the second cell 606 based on the determination that the first cell 604 is not suitable for UE / MT 608. In this case, as illustrated in step 7, network node 602 may transmit a handover command to UE / MT 608 and the second cell 606 instructing UE / MT 608 to hand over from the first cell 604 to the second cell 606.

[0107] After that, in step 8, based on the handover command, UE / MT 608 may perform an access procedure and establish a connection with the second cell 606.

[0108] Another option for mobility-aware access control may involve a distributed approach where a first wireless device (e.g., the target serving cell) and a second wireless device (e.g., UE / MT) may have the required mobility state information to appropriately control their own access (e.g., as opposed to the above centralized approach where the target cell / UE / MT does not have mobility state information and requires CU-assisted access / handover). For example, a distributed approach for mobility-aware access control may involve UE / MT and the target serving cell autonomously determining cell selection (reselection) / handover decisions based on known mobility state information.

[0109] Figure 7is a flowchart illustrating an example operation 700 for wireless communication in a network. These may include, for example, mobility-aware access control for cell selection (reselection) and / or handover according to certain aspects of the present disclosure. Operation 700 may be performed, for example, by a first wireless device (such as a target serving cell (e.g., IAB donor 405 and / or IAB node 410), a user equipment (e.g., UE 120), and / or a mobile termination component (MT) of IAB node 410). Operation 700 may be implemented as a software component executed and run on one or more processors (e.g., Figure 2 's controller / processor 240 or controller / processor 280). Additionally, signal transmission and reception performed by network nodes in operation 700 may be implemented, for example, by one or more antennas (e.g., Figure 2 's antennas 234, 252). In certain aspects, signal transmission and / or reception performed by the network may be implemented via a bus interface of one or more processors (e.g., controller / processor 240 or controller / processor 280) that obtain and / or output signals.

[0110] Operation 700 may begin at 705 by receiving one or more signals from a second wireless device in the network, where the one or more signals provide an indication of a mobility state corresponding to the second wireless device.

[0111] At 710, the first wireless device determines whether to establish a connection with the second wireless device at least in part based on the indication of the mobility state corresponding to the second wireless device.

[0112] At 715, the first wireless device takes one or more actions based on the determination.

[0113] As mentioned above, a distributed approach for mobility-aware access control may involve the UE / MT and the target serving cell autonomously determining cell selection (reselection) / handover decisions based on known mobility state information.

[0114] For example, Figure 8 is a call flow diagram illustrating an example operation performed by a first wireless device 802 (such as a UE 120 and / or an MT of IAB node 410) for mobility-aware access control for cell selection (reselection). As illustrated, at step 1, the first wireless device 802 may receive one or more signals from a second wireless device 804 (such as a target serving cell). In some cases, the target serving cell may be an MT of IAB node 410 (e.g., assuming the first wireless device is a UE) or an IAB donor 405 (e.g., assuming the first wireless device is an MT of IAB node 410).

[0115] Signals communicated in a network can take several forms and be used for various purposes. For example, additionally, in some cases, the one or more signals can include at least one of the following: a Synchronization Signal Block (SSB), a Physical Broadcast Channel (PBCH) signal, a Remaining System Information (RMSI) signal, or a Random Access Channel (RACH) Message 2 or RACH Message 4. According to various aspects, the one or more signals can provide an indication of the mobility state corresponding to a second wireless device 804. In some cases, the indication can be implicit or explicit. For example, in some cases, one or more resources used to transmit the one or more signals can implicitly indicate the mobility state corresponding to the second wireless device 804. For example, in some cases, a first type of resource used to transmit the one or more signals can correspond to a first mobility state or indicate a transition between mobility states, while a second type of resource used to transmit the one or more signals can correspond to a second mobility state or indicate a different transition between mobility states. Additionally, in some cases, the mobility state can be an explicit indication included in the one or more signals. For example, in some cases, the second wireless device can provide an explicit indication of its mobility state in RACH Message 2 or RACH Message 4. In either case, the first wireless device 802 can receive the one or more signals and determine the mobility state corresponding to the second wireless device 804.

[0116] In Figure 8 step 2 as illustrated, the first wireless device 802 can determine whether to establish a connection with the second wireless device 804. This type of determination can be at least partially or fully based on the mobility state corresponding to the second wireless device 804. In some cases, the determination can be based on one or more cell selection criteria related to the mobility state corresponding to the second wireless device 804. For example, in some cases, the one or more cell selection criteria can specify, for example, that the first wireless device 802 can only select the second wireless device 804 when the second wireless device 804 has a specific mobility state, is moving in the same direction with a mobility state similar to the first wireless device 802, or the like. According to various aspects, in some cases, the one or more cell selection criteria can be specified in a standard document and / or pre-programmed in the first wireless device 802.

[0117] Determining whether to establish a connection with the second wireless device 804 according to various aspects may include: determining to establish a connection with the second wireless device 804 when, based on an indication of a mobility state corresponding to the second wireless device 804, the one or more cell selection criteria are satisfied. For example, in some cases, if the one or more criteria specify that the second wireless device 804 must have a high-speed mobility state and the determined mobility state of the second wireless device 804 satisfies the high-speed mobility state criterion (or any other criterion related to the mobility state), the first wireless device 802 may determine to establish a connection with the second wireless device 804.

[0118] According to various aspects, if the first wireless device 802 determines to establish a connection with the second wireless device 804, then in Figure 8 step 3 in, the first wireless device 802 may take one or more actions based on this determination. For example, as illustrated, in step 3, based on this determination, the first wireless device 802 may execute an access procedure and establish a connection with the second wireless device 804.

[0119] However, in some cases, determining whether to establish a connection with the second wireless device 804 may be based on or depend on several factors. These may include, for example, determining not to establish a connection with the second wireless device 804 when, based on an indication of a mobility state corresponding to the second wireless device 804, the one or more cell selection criteria are not satisfied. For example, in some cases, if the one or more criteria specify that the second wireless device 804 must have a high-speed mobility state and the determined mobility state of the second wireless device 804 does not satisfy the high-speed mobility state criterion (or any other criterion related to the mobility state), the first wireless device 802 may determine not to establish a connection with the second wireless device 804. Thus, in this case, in step 3, although not illustrated, the first wireless device 802 may take one or more actions, such as searching for and selecting a different and more suitable second wireless device.

[0120] As mentioned above, in some cases, the first wireless device 802 may determine (or infer) the mobility state of the second wireless device 804 based on a set of measurement or location information. In other cases, the first wireless device 802 may instead determine or infer its own mobility state relative to the second wireless node 804 based on a set of measurement or location information. For example, in some cases, the first wireless device 802 may determine whether the first wireless device 802 has low mobility (e.g., is relatively static) or high mobility relative to the second wireless device 804, and in the case of high mobility, determine whether the first wireless device 802 is moving towards the second wireless node 804 or away from the second wireless node 804.

[0121] According to various aspects, after the first wireless device 802 determines the mobility state of the second wireless device 804 / the first wireless device 802, this mobility state information can be used for various purposes, such as reporting to another node (e.g., a network node or the second wireless device 804), selecting the second wireless device 804 to establish a connection with, or handing over to / from the second wireless device 804, as discussed above.

[0122] In some cases, as mentioned above, the first wireless device can be a UE (or an IAB node MT), and can measure signal metrics of the second wireless device (e.g., a cell), such as signal strength (e.g., reference signal received power (RSRP)). The first wireless device can also determine the change of certain signal metrics over a period of time, such as the change of RSRP, Doppler, RTT, etc. The first wireless device can then decide whether to camp on the cell based at least in part on these two factors (e.g., RSRP and the change of signal metrics). For example, the first wireless device can perform measurements on two cells. For example, the first wireless device can determine that the first cell has an RSRP value of X and a change of Y. Additionally, the first wireless device can determine that the second cell has an RSRP value of X + 3 dB and a change of 10Y. In this case, the first wireless device can select the first cell and camp on the first cell. For example, even if the first wireless device determines that the second cell has a stronger RSRP (and would traditionally be selected due to the stronger RSRP), however, based on the change of the signal metrics of the second cell, the first wireless device can infer that the connection to the second wireless device may be unreliable or unsuitable because the signal metrics of the second wireless device change significantly (perhaps due to a relatively high mobility with respect to the second wireless device). Therefore, the first wireless device can instead select the first wireless device with a weaker RSRP but with a more reliable / predictable connection (e.g., low change).

[0123] Figure 9 Is a call flow diagram illustrating an example operation performed by a first wireless device (such as a target cell (e.g., an MT of an IAB node 410 or an IAB donor 405)) for mobility-aware access control for cell selection (reselection).

[0124] As illustrated, at step 1, the first wireless device 902 may receive one or more signals from a second wireless device 904 (such as the MT of UE 120 or IAB node 410). In some cases, the one or more signals include at least one of a random access channel (RACH) message 1 or a RACH message 3. Additionally, in some cases, the one or more signals may provide an indication of the mobility state corresponding to the second wireless device 904. As mentioned above, the indication of the mobility state corresponding to the second wireless device 904 may be provided implicitly or explicitly. For example, in some cases, the RACH preamble ID of the RACH message 1 or the resources used to transmit the RACH message 1 may implicitly provide an indication of the mobility state corresponding to the second wireless device 904. Additionally, as mentioned, in some cases, the indication of the mobility state corresponding to the second wireless device 904 may be explicitly provided, for example, in the RACH message 1 or the RACH message 3 from the second wireless device 904.

[0125] At Figure 9 step 2, as illustrated, the first wireless device 902 may determine whether to establish a connection with the second wireless device 904. This determination of this nature may be at least partially or fully based on the mobility state corresponding to the second wireless device 904. In some cases, the determination may also be based on one or more cell selection criteria related to the mobility state corresponding to the second wireless device 904, similar to Figure 8 step 2 in

[0126] Additionally, in some cases, determining whether to establish a connection with the second wireless device 904 may include performing prioritization based on the indication of the mobility state of the second wireless device 904. For example, Figure 9The example focuses on (1) the second wireless device 904 (e.g., UE / MT) indicating its mobility state in one or more signals (such as RACH MSG1 or 3), and (2) the first wireless device 902 (e.g., the target cell) performing prioritization based on the mobility state of the second wireless device 904. According to various aspects, "prioritization" may be related to the cell "detection" phase. For example, assume the mobility state is indicated by the second wireless device 904 via RACH MSG1. The first wireless device 902 may implement a RACH receiver algorithm for detecting any UE / MT (e.g., the second wireless device 904) that transmits RACH MSG1. The implementation of this algorithm and / or the RACH MSG1 configuration may, for example, prioritize detecting one category over another by allocating more resources to one category or by searching for RACH MSG1 of one category more broadly (e.g., more frequently, or using a BF configuration that achieves a higher beamforming (BF) gain). Additionally, in some cases, "prioritization" may be related to the cell "selection" phase. That is, after detecting one or more second wireless devices 904 (e.g., UE / MT), the first wireless device 902 may decide which second wireless device to select to establish a connection and which second wireless device to reject, or which second wireless device to attempt to establish a connection with first.

[0127] Thereafter, according to various aspects, determining whether to establish a connection with the second wireless device by the first wireless device 902 may include one of the following: determining to establish a connection with the second wireless device 904 based on the prioritization, or determining not to establish a connection with the second wireless device 904 based on the prioritization.

[0128] According to various aspects, if the first wireless device 902 determines to establish a connection with the second wireless device 904, then in Figure 9 step 3, the first wireless device 902 may take one or more actions based on this determination. For example, as illustrated, in step 3, based on this determination, the first wireless device 902 may perform an access procedure and establish a connection with the second wireless device 904. However, if the first wireless device 902 determines not to establish a connection with the second wireless device 904, then in step 3, the first wireless device 902 may take one or more actions, such as notifying the second wireless device 904 that a connection will not be established.

[0129] Figure 10is a flowchart illustrating an example operation 1000 for wireless communication in a network, such as mobility-aware access control for cell handover, according to some aspects of the present disclosure. Operation 1000 may be performed, for example, by a first wireless device such as a user equipment (e.g., UE 120) and / or a mobile termination (MT) component of an IAB node 410. Operation 1000 may be implemented as a software component executed and run on one or more processors (e.g., Figure 2 's controller / processor 240 or controller / processor 280). Additionally, signal transmission and reception by network nodes in operation 1000 may be implemented, for example, by one or more antennas (e.g., Figure 2 's antennas 234, 252). In some aspects, signal transmission and / or reception by the network may be implemented via a bus interface of one or more processors (e.g., controller / processor 240 or controller / processor 280) that obtain and / or output signals.

[0130] Operation 1000 may begin at 1005 with the first wireless device camping on a first cell in the network.

[0131] At 1010, the first wireless device receives one or more signals from a second cell in the network.

[0132] At 1015, the first wireless device determines mobility state information corresponding to the second cell in the network, at least in part based on the one or more signals.

[0133] At 1020, the first wireless device transmits a measurement report to a network node, at least in part based on the one or more signals from the second cell and the mobility state information corresponding to the second cell.

[0134] Figure 11 is a flowchart illustrating an example operation 1100 for wireless communication in a network, such as mobility-aware access control for cell handover, according to some aspects of the present disclosure. Operation 1100 may be performed, for example, by a network node such as a CU of an IAB donor 405. Operation 1100 may be considered complementary to operation 1000 performed by the UE 120 and / or the MT of the IAB node 410.

[0135] Operation 1100 may be implemented as a software component executed and run on one or more processors (e.g., controller / processor 240). Additionally, signal transmission and reception by network nodes in operation 1100 may be implemented, for example, by one or more antennas (e.g., Figure 2The antenna 234). In some aspects, signal transmission and / or reception by the network can be implemented via the bus interface of one or more processors (e.g., the controller / processor 240) that obtain and / or output signals.

[0136] Operation 1100 can start at 1105 by receiving a measurement report from a wireless device that is currently camped on a first cellular cell in the network, where the measurement report is based on one or more signals from a second cellular cell in the network.

[0137] At 1110, the network node determines whether to initiate a handover procedure for handing over the wireless device to the second cellular cell, at least in part based on the mobility state information corresponding to the second cellular cell.

[0138] At 1115, the network node takes one or more actions based on the determination.

[0139] Figure 12 is a call flow diagram illustrating example operations for mobility-aware access control for cell handover according to some aspects of the present disclosure. Figure 12 The example operations illustrated in Figure 10 and Figure 11 provide a more detailed illustration of operations 1000 and 1100 illustrated in

[0140] As illustrated, in Figure 12 step 1, the first wireless device 1202 (e.g., the UE 120 and / or the MT of the IAB node 410) can establish a connection and camp on the first cellular cell 1204.

[0141] In step 2, the connected first wireless device 1202 can have (or obtain) information about the mobility state of an adjacent cellular cell (such as the second cellular cell 1206). For example, in some cases, in step 2, the first wireless device 1202 can receive one or more signals from the second cellular cell 1206. According to various aspects, the first wireless device 1202 can perform one or more measurements on the one or more signals received from the second cellular cell 1206. As mentioned above, in some cases, the one or more signals can include at least one of the following: a synchronization signal block (SSB), a physical broadcast channel (PBCH) signal, a remaining system information (RMSI) signal.

[0142] Additionally, the first wireless device 1202 may determine a mobility state corresponding to the second cell 1206 based on the one or more signals received from the second cell 1206. For example, in some cases, the one or more signals may provide an indication of mobility state information corresponding to the second cell 1206 in the network. In such a case, the first wireless device 1202 may determine the mobility state information based at least in part on the indication of the mobility state information corresponding to the second cell 1206 in the network.

[0143] In step 3, the first wireless device 1202 transmits a measurement report to the network node 1208 based at least in part on the one or more signals from the second cell 1206 and the mobility state information corresponding to the second cell 1206. In some cases, as illustrated, the network node 1208 may be a CU, which in some cases may be part of the first cell 1204. In some cases, the measurement report includes an indication of the determined mobility state corresponding to the second cell 1206.

[0144] Additionally, in some cases, the first wireless device 1202 may determine whether to transmit a measurement report based on a trigger event. In some cases, the trigger event may be based on the mobility state information corresponding to the second cell 1206. In other words, the first wireless device 1202 may determine whether to transmit a measurement report corresponding to the second cell 1206 to the network node 1208 based on the mobility state corresponding to the second cell 1206 (e.g., and whether the mobility state corresponding to the second cell meets the trigger event). For example, in some cases, if the first wireless device 1202 determines that the mobility state corresponding to the second cell 1206 meets the trigger event (e.g., the mobility state of the second cell 1206 is "mobile" and the measured RSRP of the second cell 1206 is greater than a threshold RSRP), then the first wireless device 1202 may decide to transmit a measurement report to the network node 1208. However, if the first wireless device 1202 determines that the mobility state corresponding to the second cell 1206 does not meet the trigger event, then the first wireless device 1202 may decide not to transmit a measurement report to the network node 1208. According to various aspects, determining whether to transmit a measurement report based on the mobility state information corresponding to the second cell 1206 may allow the first wireless device 1202 to save time and energy by not having to report measurements for unsuitable cells (e.g., cells that do not meet the trigger event).

[0145] From the perspective of the network node 1208 (e.g., CU), at step 3, the network node 1208 may receive a measurement report from the first wireless device 1202 that is currently camped on the first cellular cell 1204 in the network. As mentioned, the measurement report may be based on one or more signals from the second cellular cell 1206 in the network (and carry information about the measurements of the one or more signals). Additionally, in some cases, the network node 1208 may receive an indication of the mobility state information corresponding to the second cellular cell 1206 from the first wireless device 1202. In some cases, the mobility state information corresponding to the second cellular cell 1206 is received in the measurement report.

[0146] At step 4, after receiving the measurement report from the first wireless device 1202, the network node 1208 may determine whether to initiate a handover procedure for handing over the first wireless device 1202 to the second cellular cell 1206, at least in part based on the mobility state information corresponding to the second cellular cell 1206. In some cases, determining whether to initiate a handover procedure for handing over the first wireless device 1202 to the second cellular cell 1206 may be based at least in part on one or more conditions related to the mobility state corresponding to the second cellular cell 1206, as discussed above, for example. Additionally, according to various aspects, determining whether to initiate the handover procedure may involve determining to initiate the handover procedure when, for example, the mobility state information corresponding to the second cellular cell 1206 satisfies the one or more conditions. Similarly, determining whether to initiate the handover procedure may involve determining not to initiate the handover procedure when, for example, the mobility state information corresponding to the second cellular cell 1206 does not satisfy the one or more conditions.

[0147] According to various aspects, at step 5, the network node 1208 may take one or more actions based on the determination of whether to initiate the handover procedure. For example, if the network node 1208 determines to initiate the handover procedure, then (as illustrated) the network node 1208 may transmit a handover command for handing over the first wireless device 1202 to the second cellular cell 1206 in the network. According to various aspects, the handover command may be transmitted to at least one of the first wireless device 1202 or the second cellular cell 1206.

[0148] Thus, at step 5, the first wireless device 1202 may receive a handover command to hand over to the second cellular cell 1206 in the network, at least in part based on at least one of the measurement report or the mobility state information corresponding to the second cellular cell 1206.

[0149] Thereafter, in step 6, the first wireless device 1202 may take one or more actions based on the handover command. For example, as illustrated in step 6, the first wireless device 1202 may perform an access procedure and establish a connection with the second wireless cell 1206. According to various aspects, if the network node 1208 decides not to initiate a handover procedure and the first wireless device 1202 does not receive a handover command, the first wireless device 1202 may start searching for other suitable neighbor cells to hand over to, repeating the operations illustrated in Figure 12 as illustrated.

[0150] In some cases, the handover command may be conditional. For example, in some cases, instead of the first wireless device providing a measurement report to the network node, in some cases, the network node may provide a conditional handover command to the first wireless device, the conditional handover command allowing the first wireless device to initiate a handover when certain conditions are met. For example, in some cases, the conditional handover command may include one or more conditions related to a mobility state corresponding to the second cell that the first wireless device wants to hand over to. According to various aspects, if the mobility state corresponding to the second cell meets one or more of these conditions in the conditional handover command, the first wireless device may initiate a handover to the second cell.

[0151] Figure 13 is a flowchart illustrating an example operation 1300 for wireless communication in a network, for example, for mobility-aware access control for cell handover according to a conditional handover command, in accordance with certain aspects of the present disclosure. Operation 1300 may be performed, for example, by a first wireless device such as a user equipment (e.g., UE 120) and / or a mobile termination component (MT) of an IAB node 410. Operation 1300 may be implemented as a software component executed and run on one or more processors (e.g., Figure 2 the controller / processor 240 or controller / processor 280). Further, signal transmission and reception performed by the network node in operation 1300 may be implemented, for example, by one or more antennas (e.g., Figure 2 the antennas 234, 252). In certain aspects, signal transmission and / or reception performed by the network may be implemented via a bus interface of one or more processors (e.g., controller / processor 240 or controller / processor 280) that obtain and / or output signals.

[0152] Operation 1300 may begin at 1305, camping on a first cell in the network.

[0153] At 1310, a first wireless device receives a conditional handover command to a second cell in the network from a network node in the network, where the conditional handover command includes one or more conditions based at least in part on a mobility state corresponding to the second cell.

[0154] At 1315, the first wireless device takes one or more actions based at least in part on the conditional handover command.

[0155] Figure 14 FIG. is a flowchart illustrating an example operation 1400 of wireless communication for mobility-aware access control in a network, such as for cell handover according to a conditional handover command, in accordance with certain aspects of the present disclosure. Operation 1400 may be performed, for example, by a network node (such as a CU of the IAB donor 405). Operation 1400 may be considered complementary to operation 1300 performed by the UE 120 and / or the MT of the IAB node 410.

[0156] Operation 1400 may be implemented as a software component executed and run on one or more processors (e.g., the controller / processor 240). Further, signal transmission and reception performed by the network node in operation 1400 may be implemented, for example, by one or more antennas (e.g., Figure 2 antenna 234). In some aspects, signal transmission and / or reception performed by the network may be implemented via a bus interface of one or more processors (e.g., the controller / processor 240) that obtain and / or output signals.

[0157] Operation 1400 may begin at 1405 by communicating with a wireless device camping on a first cell in the network in the network.

[0158] At 1410, the network node transmits a conditional handover command to a second cell in the network from a network node in the network, where the conditional handover command includes one or more conditions based at least in part on a mobility state corresponding to the second network.

[0159] Figure 15 FIG. is a call flow diagram illustrating an example operation for mobility-aware access control for cell handover according to a conditional handover command. Figure 15 The example operations illustrated in Figure 13 and Figure 14 provide a more detailed illustration of operations 1300 and 1400 illustrated respectively in

[0160] As illustrated, in Figure 15In step 1, the first wireless device 1502 (e.g., the MT of UE 120 and / or IAB node 410) may establish a connection and camp on the first cellular cell 1504.

[0161] In step 2, the first wireless device 1502 may receive a conditional handover command to hand over to a second cellular cell 1506 in the network from a network node 1508 (such as a CU) in the network. In some cases, the conditional handover command includes one or more conditions that are at least partially based on the mobility state corresponding to the second cellular cell 1506. In other words, the conditional handover may include one or more conditions related to the mobility state corresponding to the second cellular cell 1206 that the first wireless device 1202 wants to hand over to.

[0162] According to various aspects, although Figure 15 not illustrated herein, in some cases, the conditional handover command may be at least partially based on prior measurement information or prior location information associated with at least one of the first wireless device 1502 or the second cellular cell 1506. For example, in some cases, the network node 1508 may receive measurement information or location information corresponding to one or more cellular cells (e.g., the second cellular cell 1506) in the network at a previous time, as described above. Based on the prior information, the network node 1508 may generate a conditional handover command and transmit the generated conditional handover command to the first wireless device 1502, where the one or more conditions are based on the prior information corresponding to the one or more cellular cells (e.g., the second cellular cell 1506).

[0163] In step 3, the first wireless device 1502 may take one or more actions based on the conditional handover command. For example, in some cases, the first wireless device 1502 may receive one or more signals from the second cellular cell 1506 and determine the mobility state corresponding to the second cellular cell 1506 based on the one or more signals.

[0164] Additionally, in some cases, taking one or more actions may include determining whether to switch to the second cellular cell 1506 at least in part based on the one or more signals and the one or more conditions in the conditional handover command. In some cases, determining whether to switch to the second cellular cell 1506 may include, for example, initiating a handover procedure for switching to the second cellular cell 1506 if the one or more conditions are at least in part satisfied based on the one or more signals. For example, in some cases, if the first wireless device 1502 determines that the determined mobility state information corresponding to the second cellular cell 1506 satisfies one or more of the conditions in the conditional handover command, the first wireless device 1502 may decide to initiate a handover procedure for switching to the second cellular cell 1506. Additionally, in some cases, determining whether to switch to the second cellular cell 1506 may include determining not to switch to the second cellular cell 1506 if the one or more conditions are at least in part not satisfied based on the one or more signals. For example, if the first wireless device 1502 determines that the determined mobility state information corresponding to the second cellular cell 1506 does not satisfy one or more of the conditions in the conditional handover command, the first wireless device 1502 may decide not to initiate a handover procedure for switching to the second cellular cell 1506.

[0165] In step 5, if the first wireless device 1502 decides to switch to the second cellular cell 1506, the first wireless device 1502 may take one or more actions such as performing an access procedure and establishing a connection with the second cellular cell 1506.

[0166] Additionally, although not illustrated, if the first wireless device 1502 is switched to the second cellular cell 1506, the network node 1508 may receive an indication that the first wireless device 1502 has been switched to the second cellular cell 1506 (e.g., based on the conditional handover command). In some cases, the indication that the first wireless device 1502 has been switched to the second cellular cell 1506 may be received from at least one of the second cellular cell 1506 or the first wireless device 1502.

[0167] Figure 16 Illustrations may include being configured to perform operations for the techniques disclosed herein (such as Figures 5 - 15A communication device 1600 for various components (e.g., corresponding to device plus function components) of the operations illustrated in [reference] and other techniques for mobility-aware access control described herein. The communication device 1600 includes a processing system 1602 coupled to a transceiver 1608. The transceiver 1608 is configured to transmit and receive signals (such as various signals described herein) for the communication device 1600 via an antenna 1610. The processing system 1602 may be configured to perform processing functions for the communication device 1600, including processing signals received and / or to be transmitted by the communication device 1600.

[0168] The processing system 1602 includes a processor 1604 coupled to a computer-readable medium / memory 1612 via a bus 1606. In some aspects, the computer-readable medium / memory 1612 is configured to store instructions (e.g., computer-executable code) that, when executed by the processor 1604, cause the processor 1604 to perform Figures 5 - 15 the operations illustrated in [reference] or other operations for performing various techniques for mobility-aware access control discussed herein. In some aspects, the computer-readable medium / memory 1612 stores code for performing Figures 5 - 15 the operations illustrated in [reference] and other techniques for mobility-aware access control described herein. For example, the computer-readable medium / memory 1612 stores code 1614 for obtaining, code 1616 for receiving, code 1618 for determining, code 1620 for taking one or more actions, code 1622 for camping, code 1624 for transmitting, and code 1626 for communicating.

[0169] In some aspects, the processor 1604 may include circuitry configured to implement the code stored in the computer-readable medium / memory 1612, such as for performing Figures 5 - 15 the operations illustrated in [reference] and other techniques for mobility-aware access control described herein. For example, the processor 1604 includes circuitry 1628 for obtaining, circuitry 1630 for receiving, circuitry 1632 for determining, circuitry 1634 for taking one or more actions, circuitry 1636 for camping, circuitry 1638 for transmitting, and circuitry 1640 for communicating.

[0170] The techniques described herein can be used in a variety of wireless communication technologies such as NR (e.g., 5G NR), 3GPP Long Term Evolution (LTE), LTE-Advanced (LTE-A), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are often used interchangeably. CDMA networks may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers the IS-2000, IS-95, and IS-856 standards. TDMA networks may implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA networks can implement radio technologies such as NR (e.g., 5G RA), 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 Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are UMTS versions that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). NR is an emerging wireless communication technology under development.

[0171] The techniques described herein can be used in the wireless networks and radio technologies mentioned above and other wireless networks and radio technologies. For clarity, while aspects may be described herein using terms typically associated with 3G, 4G, and / or 5G wireless technologies, aspects of the present disclosure can be applied in communication systems based on other generations.

[0172] In 3GPP, the term "cell" may refer to the coverage area of a Node B (NB) and / or the NB subsystem serving that coverage area, depending on the context in which the term is used. In the NR system, the terms "cell" and BS, next-generation Node B (gNB or g Node B), access point (AP), distributed unit (DU), carrier, or transmit receive point (TRP) may be used interchangeably. A BS may provide communication coverage for macro cells, picocells, femtocells, and / or other types of cells. A macro cell may cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unconstrained access by UEs with a service subscription. A picocell may cover a relatively small geographical area and may allow unconstrained access by UEs with a service subscription. A femtocell may cover a relatively small geographical area (e.g., a residence) and may allow constrained access by UEs associated with that femtocell (e.g., UEs in a closed subscriber group (CSG), UEs of users in a residence, etc.). The BS for a macro cell may be referred to as a macro BS. The BS for a picocell may be referred to as a pico BS. The BS for a femtocell may be referred to as a femto BS or a home BS.

[0173] A UE may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, customer premise equipment (CPE), cellular phone, smartphone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, appliance, medical device or equipment, biometric sensor / device, wearable device (such as a smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music device, video device, satellite radio, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, global positioning system device, or any other suitable device configured to communicate via wireless or wired media. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) or provide connectivity to the network, for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0174] Some wireless networks (e.g., LTE) utilize Orthogonal Frequency Division Multiplexing (OFDM) on the downlink and Single Carrier Frequency Division Multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also often referred to as frequency tones, frequency bins, etc. Each subcarrier can be modulated with data. Generally speaking, the modulation symbols are transmitted in the frequency domain for OFDM and in the time domain for SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the subcarrier spacing can be 15 kHz, and the minimum resource allocation (referred to as a "resource block" (RB)) can be 12 subcarriers (or 180 kHz). Thus, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal Fast Fourier Transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth can also be divided into subbands. For example, a subband can cover 1.08 MHz (e.g., 6 RBs), and for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, there can be 1, 2, 4, 8, or 16 subbands, respectively. In LTE, the basic transmission time interval (TTI) or packet duration is a 1 ms subframe.

[0175] NR can utilize OFDM with CP on both the uplink and downlink and includes support for half-duplex operation using TDD. In NR, a subframe is still 1 ms, but the basic TTI is called a slot. A subframe contains a variable number of slots (e.g., 1, 2, 4, 8, 16... slots), which depends on the subcarrier spacing. An NR RB is 12 consecutive frequency subcarriers. NR can support a base subcarrier spacing of 15 kHz, and other subcarrier spacings can be defined relative to the base subcarrier spacing, e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. The CP length also depends on the subcarrier spacing. Beamforming can be supported and the beam direction can be configured dynamically. MIMO transmission with precoding can also be supported. In some examples, the MIMO configuration in the DL can support up to 8 transmit antennas (multi-layer DL transmission with up to 8 streams) and up to 2 streams per UE. In some examples, multi-layer transmission with up to 2 streams per UE can be supported. Up to 8 serving cells can be used to support the aggregation of multiple cells.

[0176] In some examples, access to the air interface can be scheduled. A scheduling entity (e.g., a BS) allocates resources for communication among some or all of the devices and equipment within its service area or cell. The scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for the scheduled communication, the subordinate entities utilize the resources allocated by the scheduling entity. A base station is not the only entity that can serve as a scheduling entity. In some examples, a UE may act as a scheduling entity and may schedule resources for one or more subordinate entities (e.g., one or more other UEs), and the other UEs may utilize the resources scheduled by the UE for wireless communication. In some examples, a UE may act as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In a mesh network example, UEs may communicate directly with each other in addition to communicating with a scheduling entity.

[0177] In some examples, two or more subordinate entities (e.g., UEs) may communicate with each other using sidelink signals. Real-world applications of such sidelink communication may include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communication, Internet of Everything (IoE) communication, IoT communication, mission-critical mesh, and / or various other suitable applications. Generally, a sidelink signal may refer to a signal that is communicated from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., a UE or a BS), even though a scheduling entity may be used for scheduling and / or control purposes. In some examples, sidelink signals may be communicated using licensed spectrum (different from wireless local area networks, which typically use unlicensed spectrum).

[0178] The various methods disclosed herein include one or more steps or acts for implementing the method. These method steps and / or acts may be interchanged with one another without departing from the scope of the claims. In other words, unless a specific order of the steps or acts is specified, the order and / or use of the specific steps and / or acts may be altered without departing from the scope of the claims.

[0179] As used herein, a phrase that recites "at least one of" a list of items refers to any combination of those items, including a single member. As an example, "at least one of a, b, or c" is intended to cover: a, b, c, a - b, a - c, b - c, and a - b - c, as well as any combination having multiple identical elements (e.g., a - a, a - a - a, a - a - b, a - a - c, a - b - b, a - c - c, b - b, b - b - b, b - b - c, c - c, and c - c - c, or any other ordering of a, b, and c).

[0180] As used herein, the term "determine" encompasses a variety of actions. For example, "determine" can include computing, calculating, processing, deriving, researching, looking up (e.g., looking up in a table, database, or other data structure), ascertaining, and the like. Also, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and the like. Also, "determine" can include parsing, selecting, choosing, establishing, and the like.

[0181] The foregoing description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other aspects. Thus, the claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the language of the claims, where the recitation of a singular element is not intended to mean "one and only one" (unless specifically so stated) but "one or more." Unless specifically stated otherwise, the term "some / a" means one or more. Elements of the various aspects described throughout this disclosure that are presently known or later come to be known to those of ordinary skill in the art as all structural and functional equivalents thereof are expressly incorporated herein by reference and are intended to be covered by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public, whether or not such disclosure is expressly recited in the claims. No element of a claim should be construed under the provisions of 35 U.S.C. § 112(f) unless the element is expressly recited using the phrase "means for" or, in the case of a method claim, the element is recited using the phrase "step for."

[0182] The various operations of the methods described above can be performed by any suitable means capable of performing the corresponding functions. These means can include various hardware and / or software components and / or modules, including but not limited to circuits, application specific integrated circuits (ASICs), or processors. Generally, where there are operations illustrated in the figures, these operations may have corresponding paired means-plus-function components with similar numbers.

[0183] The various illustrative logical blocks, modules, and circuits described in connection with the present disclosure may be implemented or performed with a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0184] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented with a bus architecture. Depending on the particular application and overall design constraints of the processing system, the bus may include any number of interconnecting buses and bridges. The bus may link together various circuits including a processor, machine-readable media, and a bus interface. The bus interface may be used to connect a network adapter, etc. to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In the case of the user equipment 120 (see Figure 1 ), a user interface (e.g., keypad, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits such as a timing source, peripherals, voltage regulators, power management circuits, and similar circuits that are well known in the art and will not be described further herein. The processor may be implemented with one or more general and / or dedicated processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuitry capable of executing software. Depending on the particular application and overall design constraints imposed on the overall system, those of ordinary skill in the art will recognize how best to implement the functionality described with respect to the processing system.

[0185] If implemented in software, each function may be stored on or transmitted via a computer-readable medium as one or more instructions or code. Software should be construed broadly to mean instructions, data, or any combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. A computer-readable medium includes both computer storage media and communication media, including any medium that facilitates transfer of a computer program from one place to another. A processor may be responsible for managing the bus and general processing, including executing software modules stored on a machine-readable storage medium. The computer-readable storage medium may be coupled to the processor such that the processor can read from and write to the storage medium. In an alternative, the storage medium may be integrated into the processor. As an example, the machine-readable medium may include transmission lines, a carrier modulated with data, and / or a computer-readable storage medium separate from a wireless node that stores instructions thereon, all of which may be accessed by the processor via a bus interface. Alternatively or additionally, the machine-readable medium or any part thereof may be integrated into the processor, such as may be the case with a cache and / or a general register file. As an example, examples of the machine-readable medium may include RAM (random access memory), flash memory, ROM (read-only memory), PROM (programmable read-only memory), EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable read-only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage medium, or any combination thereof. The machine-readable medium may be embodied in a computer program product.

[0186] Software modules may include a single instruction or many instructions and may be distributed over several different code segments, among different programs, and across multiple storage media. A computer-readable medium may include several software modules. These software modules include instructions that, when executed by an apparatus such as a processor, cause a processing system to perform various functions. These software modules may include a transmitting module and a receiving module. Each software module may reside in a single storage device or be distributed across multiple storage devices. As an example, when a triggering event occurs, a software module may be loaded from a hard drive into RAM. During execution of the software module, the processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into the general register file for execution by the processor. When referring to the functionality of a software module hereinafter, it will be understood that such functionality is implemented by the processor when the processor executes instructions from the software module.

[0187] Similarly, any connection is properly termed a computer-readable medium. For example, if software is transmitted from a web site, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), or wireless technology such as infrared (IR), radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology such as infrared, radio, and microwave is included in the definition of the medium. As used herein, disk and disc include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and disc, where disk typically reproduces data magnetically, while disc reproduces data optically with a laser. Thus, in some aspects, a computer-readable medium may include a non-transitory computer-readable medium (e.g., a tangible medium). Additionally, for other aspects, a computer-readable medium may include a transitory computer-readable medium (e.g., a signal). Combinations of the above should also be included within the scope of computer-readable media.

[0188] Accordingly, some aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having instructions stored (and / or encoded) thereon that can be executed by one or more processors to perform the operations described herein, e.g., instructions for performing the operations described and illustrated in Figures 5 - 15 and other techniques for mobility-aware access control described herein.

[0189] Furthermore, it should be appreciated that modules and / or other suitable means for performing the methods and techniques described herein can be downloaded and / or otherwise obtained by a user terminal and / or a base station, where applicable. For example, such devices can be coupled to a server to facilitate the transfer of means for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage device (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or floppy disk, etc.) such that once the storage device is coupled to or provided to the user terminal and / or base station, the device can obtain the various methods. Additionally, any other suitable technology can be utilized that is adapted to provide the methods and techniques described herein to a device.

[0190] It will be understood that the claims are not limited to the exact configurations and components described above. Various changes, substitutions, and modifications can be made in the layout, operation, and details of the methods and apparatuses described above without departing from the scope of the claims.
