[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 705,659, filed on July 9, 2020, entitled “ADMISSION CONTROL FOR RADIORESOURCE CONTROL SETUP PROCEDURE,” and U.S. Non-Provisional Patent Application No. 17 / 304,905, filed on June 28, 2021, entitled “ADMISSION CONTROL FOR RADIO RESOURCE CONTROL SETUP PROCEDURE,” which are hereby expressly incorporated herein by reference.

[0003] Public domain

[0004] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for admission control for radio resource control (RRC) setup procedures.

[0005] background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless network may include several base stations (BSs) that can support communications for several user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, while an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies are still useful.

[0033] Detailed Description

[0034] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is independently implemented or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0035] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0036] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0037] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, a B node, a gNB, a 5G B node (NB), an access point, a transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0038] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0039] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0040] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0041] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0042] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0043] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0044] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network) via, for example, a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0045] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0046] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0047] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) and / or may communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) may span 410 MHz to 7.125 GHz, and the second frequency range (FR2) may span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz" and the like, if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave" and the like, if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0048] In some aspects, the wireless network 100 may include one or more non-terrestrial network (NTN) deployments, where non-terrestrial wireless communication devices may include BSs (interchangeably referred to herein as "non-terrestrial BSs" and "non-terrestrial base stations"), relay stations (interchangeably referred to herein as "non-terrestrial relay stations"), etc. As used herein, "NTN" may refer to a network to which access is facilitated by non-terrestrial BSs, non-terrestrial relay stations, etc.

[0049] The wireless network 100 may include any number of non-terrestrial wireless communication devices. The non-terrestrial wireless communication devices may include satellites, high altitude platforms (HAPs), and the like. The HAPs may include balloons, airships, airplanes, unmanned aerial vehicles, and the like. The non-terrestrial wireless communication devices may be part of an NTN that is separate from the wireless network 100. Alternatively, the NTN may be part of the wireless network 100. The satellites may communicate directly and / or indirectly with other entities in the wireless network 100 using satellite communications. The other entities may include UEs, other satellites in one or more NTN deployments, other types of BSs (e.g., stationary or ground-based BSs), relay stations, one or more components and / or devices included in the core network of the wireless network 100, and the like.

[0050] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described herein. Figure 1 Examples described.

[0051] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0052] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0053] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0054] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0055] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).

[0056] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, where applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described with reference to Figure 6-10 described).

[0057] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as described with reference to Figure 6-10 described).

[0058] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the base station 110 may perform one or more techniques associated with admission control for the RRC setup procedure, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) may perform or direct e.g. Fig.11 Process 1100, Fig.12 1200, and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include: a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Fig.11 Process 1100, Fig.12 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other aspects.

[0059] In some aspects, UE 120 may include: means for transmitting a message indicating a location of a user equipment to a base station associated with a non-terrestrial network in conjunction with a random access procedure; means for receiving a response to the message, the response indicating whether the message was accepted or rejected, the response based at least in part on the location; etc. In some aspects, such means may include means for transmitting a message indicating a location of a user equipment to a base station associated with a non-terrestrial network in conjunction with a random access procedure; means for receiving a response to the message, the response indicating whether the message was accepted or rejected, the response based at least in part on the location; etc. Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0060] In some aspects, base station 110 may include: means for receiving a message indicating a location of the user equipment from the user equipment in conjunction with a random access procedure; means for determining whether the message is accepted or rejected based at least in part on the location; means for transmitting a response to the message, the response indicating whether the message is accepted or rejected; etc. In some aspects, such means may include means for receiving a message indicating a location of the user equipment from the user equipment in conjunction with a random access procedure; means for determining whether the message is accepted or rejected based at least in part on the location; means for transmitting a response to the message, the response indicating whether the message is accepted or rejected; etc. Figure 2One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0061] although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functions described above with respect to these blocks may be implemented using a single hardware, software, or combined component or a combination of various components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0062] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described herein. Figure 2 Examples described.

[0063] Figure 3 is a diagram illustrating an example 300 of a regenerative satellite deployment and an example 310 of a transparent satellite deployment in a non-terrestrial network.

[0064] Example 300 illustrates a regenerative satellite deployment. In example 300, UE 120 is served by satellite 320 via service link 330. For example, satellite 320 may be or include BS 110 (e.g., BS 110a), gNB, etc. In some aspects, satellite 320 may be referred to as a non-terrestrial base station, a regenerative repeater, an onboard processing repeater, etc. In some aspects, satellite 320 may demodulate uplink radio frequency signals and may modulate baseband signals derived from the uplink radio signals to produce downlink radio frequency transmissions. Satellite 320 may transmit downlink radio frequency signals on service link 330. Satellite 320 may provide a cellular cell covering UE 120.

[0065] Example 310 shows a transparent satellite deployment, which may also be referred to as a bent-pipe satellite deployment. In example 310, UE 120 is served by satellite 340 via service link 330. Satellite 340 may be referred to as a transparent satellite. Satellite 340 may relay signals received from gateway 350 via feeder link 360. For example, a satellite may receive an uplink radio frequency transmission, and may transmit a downlink radio frequency transmission without demodulating the uplink radio frequency transmission. In some aspects, the satellite may convert the uplink radio frequency transmission frequency received on service link 330 to the frequency of the uplink radio frequency transmission on feeder link 360, and may amplify and / or filter the uplink radio frequency transmission. In some aspects, the UE 120 shown in examples 300 and 310 may be associated with global navigation satellite system (GNSS) capabilities, global positioning system (GPS) capabilities, etc., but not all UEs have these capabilities. Satellite 340 may provide a cellular cell covering UE 120.

[0066] The service link 330 may include a link between the satellite 340 and the UE 120, and may include one or more of an uplink or a downlink. The feeder link 360 may include a link between the satellite 340 and the gateway 350, and may include one or more of an uplink (e.g., from the UE 120 to the gateway 350) or a downlink (e.g., from the gateway 350 to the UE 120).

[0067] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.

[0068] Figure 4 4 is a diagram illustrating an example 400 of a four-step random access procedure according to the present disclosure. Figure 4 As shown in , base station 110 and UE 120 may communicate with each other to perform a four-step random access procedure.

[0069] As indicated by reference numeral 405, the base station 110 may transmit and the UE 120 may receive one or more SSBs, and random access configuration information. In some aspects, the random access configuration information may be transmitted and / or indicated by system information (e.g., one or more system information blocks (SIBs), etc.) and / or SSBs, such as for contention-based random access. Additionally or alternatively, the random access configuration information may be transmitted in a radio resource control (RRC) message and / or a physical downlink control channel (PDCCH) command message that triggers a RACH procedure, such as for contention-free random access (CFRA). The random access configuration information may include one or more parameters to be used in the random access procedure, such as one or more parameters for transmitting a RAM, one or more parameters for receiving a RAR, and the like.

[0070] As indicated by reference numeral 410, UE 120 may transmit a RAM, which may include a preamble (sometimes referred to as a random access preamble, a PRACH preamble, a RAM preamble, etc.). The message including the preamble may be referred to as message 1 in a four-step random access procedure, msg1, MSG1, a first message, an initial message, etc. The random access message may include a random access preamble identifier.

[0071] As indicated by reference numeral 415, the base station 110 may transmit a RAR in reply to the preamble. The message including the RAR may be referred to as message 2, msg2, MSG2, or a second message in a four-step random access procedure. In some aspects, the RAR may indicate a detected random access preamble identifier (e.g., received from the UE 120 in msg1). Additionally or alternatively, the RAR may indicate a resource allocation to be used by the UE 120 to transmit message 3 (msg3).

[0072] In some aspects, as part of the second step of the four-step random access procedure, the base station 110 may transmit a PDCCH communication for the RAR. The PDCCH communication may schedule a PDSCH communication including the RAR. For example, the PDCCH communication may indicate a resource allocation for the PDSCH communication. Also as part of the second step of the four-step random access procedure, the base station 110 may transmit a PDSCH communication for the RAR as scheduled by the PDCCH communication. The RAR may be included in the MAC PDU of the PDSCH communication.

[0073] As indicated by reference numeral 420, UE 120 may transmit an RRC connection request message. The RRC connection request message may be referred to as message 3, msg3, MSG3, or a third message of a four-step random access procedure. In some aspects, the RRC connection request may include a UE identifier, a UCI, a PUSCH communication (e.g., an RRC connection request), etc. In some aspects, the RRC connection request message may indicate a location of UE 120, as described in greater detail elsewhere herein.

[0074] As indicated by reference numeral 425, base station 110 may transmit an RRC connection setup message. The RRC connection setup message may be referred to as message 4, msg4, MSG4, or a fourth message of a four-step random access procedure. In some aspects, the RRC connection setup message may include a detected UE identifier, a timing advance value, contention resolution information, and the like. As indicated by reference numeral 430, if UE 120 successfully receives the RRC connection setup message, UE 120 may transmit a HARQ ACK.

[0075] In some aspects, UE 120 may transmit an RRC connection setup complete message (sometimes referred to as message 5, msg5, MSG5, or fifth message of the four-step random access procedure). The RRC connection setup complete message may indicate that the RRC connection setup based at least in part on the RRC connection setup message has been successful. In some aspects, the RRC connection setup complete message may indicate the location of UE 120, as described in more detail elsewhere herein.

[0076] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0077] Figure 5 is a diagram illustrating an example 500 of a two-step random access procedure according to the present disclosure. Figure 5 As shown in , base station 110 and UE 120 may communicate with each other to perform a two-step random access procedure.

[0078] As indicated by reference numeral 505, the base station 110 may transmit and the UE 120 may receive one or more synchronization signal blocks (SSBs), and random access configuration information. In some aspects, the random access configuration information may be transmitted and / or indicated by system information (e.g., one or more system information blocks (SIBs), etc.) and / or SSBs, such as for contention-based random access. Additionally or alternatively, the random access configuration information may be transmitted in a radio resource control (RRC) message and / or a physical downlink control channel (PDCCH) command message that triggers a RACH procedure, such as for contention-free random access. The random access configuration information may include one or more parameters to be used in a two-step random access procedure, such as one or more parameters for transmitting a random access message (RAM), receiving a random access response (RAR) to a RAM, and the like.

[0079] As indicated by reference numeral 510, the UE 120 may transmit and the base station 110 may receive a RAM preamble. As indicated by reference numeral 515, the UE 120 may transmit and the base station 110 may receive a RAM payload. As shown, as part of the initial (or first) step of the two-step random access procedure, the UE 120 may transmit a RAM preamble and a RAM payload to the base station 110. In some aspects, the RAM may be referred to as message A, msgA, first message, initial message, etc. in the two-step random access procedure. In addition, in some aspects, the RAM preamble may be referred to as a message A preamble, msgA preamble, preamble, physical random access channel (PRACH) preamble, etc., and the RAM payload may be referred to as a message A payload, msgA payload, payload, etc. In some aspects, the RAM may include some or all of the contents of message 1 (msg1) and message 3 (msg3) of the four-step random access procedure. For example, the RAM preamble may include some or all of the contents of message 1 (e.g., a PRACH preamble), and the RAM payload may include some or all of the contents of message 3 (e.g., a UE identifier, uplink control information (UCI), a physical uplink shared channel (PUSCH) transmission, etc.). In some aspects, the RAM preamble and / or the RAM payload may indicate the location of the UE 120, as described in more detail elsewhere herein.

[0080] As indicated by reference numeral 520, the base station 110 may receive the RAM preamble transmitted by the UE 120. If the base station 110 successfully receives and decodes the RAM preamble, the base station 110 may then receive and decode the RAM payload.

[0081] As indicated by reference numeral 525, the base station 110 may transmit a RAR (sometimes referred to as a RAR message). As shown, the base station 110 may transmit a RAR message as part of a second step of a two-step random access procedure. In some aspects, the RAR message may be referred to as message B, msgB, or a second message in a two-step random access procedure. The RAR message may include some or all of the contents of message 2 (msg2) and message 4 (msg4) of a four-step random access procedure. For example, the RAR message may include a detected RACH preamble identifier, a detected UE identifier, a timing advance value, contention resolution information, etc.

[0082] As part of the second step of the two-step random access procedure, the base station 110 may transmit a physical downlink control channel (PDCCH) communication for the RAR, as indicated by reference numeral 530. The PDCCH communication may schedule a physical downlink shared channel (PDSCH) communication including the RAR. For example, the PDCCH communication may indicate a resource allocation for the PDSCH communication (e.g., in downlink control information (DCI)).

[0083] As part of the second step of the two-step random access procedure, the base station 110 may transmit a PDSCH communication for the RAR as scheduled by the PDCCH communication, as indicated by reference numeral 535. The RAR may be included in a medium access control (MAC) protocol data unit (PDU) of the PDSCH communication. As indicated by reference numeral 540, if the UE 120 successfully receives the RAR, the UE 120 may transmit a hybrid automatic repeat request (HARQ) acknowledgment (ACK).

[0084] In some aspects, UE 120 may transmit an RRC connection setup complete message. The RRC connection setup complete message may indicate that the RRC connection setup based at least in part on the RRC connection setup message has been successful. In some aspects, the RRC connection setup complete message may indicate the location of UE 120, as described in more detail elsewhere herein.

[0085] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.

[0086] Satellites in NTN can provide services to UEs covered by a cell, where the satellite provides services to the cell. As used herein, "satellite" refers to any non-terrestrial wireless communication device, such as a satellite that provides services to a UE covered by a cell. Figure 1 and 3As described. Cells in NTN are generally larger than cells in terrestrial networks. In addition, since satellites in NTN orbit the earth, cells provided by satellites can move across the ground. As a result, it is possible that UEs in multiple different areas (from the network's perspective) (such as two or more areas associated with different mobile country codes (MCCs), two or more areas associated with different type allocation codes (TACs), etc.) are covered by a single satellite and cell, which is generally not expected in terrestrial networks.

[0087] Areas associated with different MCCs or TACs may be associated with different core networks. For example, a first MCC may be associated with a first core network, and a second MCC may be associated with a second core network different from the first core network. In a scenario where a cell covers two different areas with two different MCCs, and a satellite serving the cell is associated with the first MCC, a UE in an area associated with the second MCC may initialize a connection with the satellite. For example, the UE may initiate a random access procedure, such as a physical random access (RACH) procedure, to establish a connection with the satellite. However, certain communication establishment procedures occur via the core network. Thus, if the UE initiates a communication establishment procedure from an area associated with the second MCC, the satellite may not be able to transmit a radio resource control (RRC) rejection message to the UE via the core network associated with the first MCC or reroute the UE to an appropriate core network. Thus, the UE may reside on the cell without performing a registration update for the first MCC, thereby reducing coverage of the UE in a scenario where the cell covers two areas with different MCCs, and causing regulatory issues that vary from country to country.

[0088] Some techniques and apparatus described herein provide for a radio access network (e.g., a non-terrestrial wireless communication device or base station) to perform admission control for a communication establishment procedure (such as a random access procedure) based at least in part on the location of a UE during a random access procedure. For example, a UE may provide information indicating the location of the UE, such as information indicating an MCC of the UE, information indicating one or more neighboring cells of the UE (from which the location of the UE may be determined), or other information described herein. Based at least in part on the location of the UE, the radio access network may selectively accept or reject a connection with the UE, or may trigger a handover (HO) or redirection of the UE to another cell or beam. In this way, the radio access network may handle a random access attempt of a UE on a cell associated with an MCC different from the location of the UE, thereby reducing the likelihood that the UE incorrectly camps on a cell. In addition, waiting time and network interruptions associated with random access attempts are reduced.

[0089] Figure 66 is a diagram illustrating example 600 of signaling associated with location-based admission control for non-terrestrial networks according to the present disclosure. Example 600 relates to an indication of a location associated with a UE in an RRC setup request message (such as a payload of a four-step RACH Msg3 or a two-step RACH MsgA). As shown, example 600 includes a non-terrestrial wireless communication device (shown as BS 110) and UE 120. Although example 600 (and other examples described herein) may refer to a random access procedure, the operations described with respect to example 600 and other examples described herein may be applied to other forms of communication establishment procedures.

[0090] like Figure 6 1 and indicated by reference numeral 605, BS 110 may transmit and UE 120 may receive system information (e.g., system information blocks (SIBs), etc.). In some aspects, the system information may include information related to transmitting information indicating the location of UE 120 in conjunction with a random access procedure. For example, the system information may indicate whether UE 120 is to provide information indicating the location of UE 120 to BS 110, or may indicate a method for indicating the location. In some aspects, BS 110 may transmit system information indicating that UE 120 is to provide information indicating the location based at least in part on a cellular cell provided by BS 110 covering at least a portion of two or more areas.

[0091] In some aspects, the system information may indicate that the UE 120 is to indicate location using the MCC of the UE 120. In some aspects, the system information may indicate that the UE 120 is to indicate location using a virtual cell identifier or a geographic region identifier (eg, a configured geographic region identifier).

[0092] In some aspects, the system information may indicate that the UE 120 is to indicate the location of the UE 120 based at least in part on measurements made by the UE 120, such as by reporting a set of physical cell identifiers (PCIs) or a set of beam identifiers for a set of strongest neighbor cells for the UE 120. For example, the system information may indicate which neighbor cells are to be measured and / or reported. Additionally or alternatively, the system information may indicate conditions to be used to determine whether to identify the measured cell as the location of the UE 120, such as conditions based at least in part on a measurement threshold (e.g., a reference signal received power (RSRP) threshold, a reference signal received quality (RSRQ) threshold, a signal to interference plus noise ratio (SINR) threshold, etc.). In this case, the measurement threshold may be defined as a difference relative to a serving cell of the UE 120. In some aspects, information indicating the condition may be provided to the UE 120 (e.g., via unicast signaling or an RRC connection).

[0093] In some aspects, the system information may indicate a message class for the RRC setup request message used to carry information indicating the location. For example, in some aspects, the RRC setup request message may use a 64-bit format such as associated with an uplink common control channel (CCCH1) message class. In this case, the system information may indicate whether the RRC setup request message is to use the 64-bit format associated with the CCCH1 message class or the format associated with the CCCH message class.

[0094] As indicated by reference numeral 610, UE 120 may transmit a RAM preamble to BS 110. In some aspects, UE 120 may use a preamble associated with requesting a larger uplink grant for a subsequent RAM. For example, if UE 120 is to provide information indicating a location in RACH Msg3, UE 120 may use a RAM preamble to cause BS 110 to provide an uplink grant associated with a larger RACH Msg3 in the RAM. UE 120 may select a RAM preamble from a preamble pool, or may use a dedicated PRACH resource to transmit the RAM preamble. As indicated by reference numeral 615, BS 110 may transmit a RAR including a preamble reply to UE 120.

[0095] As indicated by reference numeral 620, a UE 120 may determine a location of the UE 120. In some aspects, the UE 120 may determine an MCC indicative of the location. In some aspects, the UE 120 may determine a virtual cell identifier indicative of the location. In some aspects, the UE 120 may determine a zone identifier indicative of the location. In some aspects, the UE 120 may perform one or more measurements to identify one or more neighbor cells of the UE 120. In this case, the one or more neighbor cells may be used to determine the location of the UE 120. Thus, information identifying the one or more neighbor cells is referred to herein as information indicative of the location of the UE 120.

[0096] In some aspects, UE 120 may determine that UE 120 cannot determine location. For example, UE 120 may determine that measurements of neighbor cells have failed, and / or may determine that a zone identifier or a virtual cell identifier cannot be determined, and thus may not be able to determine location. In this case, UE 120 may transmit at least a portion of a 5G S Temporary Mobile Subscriber Identity (5G-S-TMSI), such as a larger portion of the 5G-S-TMSI than if UE 120 successfully determined location. In this case, UE 120 may provide an indicator as to whether a message (e.g., the message shown by reference numeral 625) indicates a location.

[0097] As indicated by reference numeral 625, UE 120 may transmit in the RAM information indicating the location of UE 120. For example, in example 600, UE 120 may transmit in the RRC SETUP REQUEST message information indicating the location of UE 120. In some other aspects, UE 120 may transmit in a different message (such as an RRC CONNECTION SETUP COMPLETE message, such as in conjunction with Figure 7 120). The information indicating the location of the UE 120 may include, for example, an MCC, a virtual cell identifier, a zone identifier, information indicating one or more cells determined to be neighbor cells (e.g., based at least in part on one or more measurements performed by the UE 120), latitude and longitude values, and the like. In some aspects, the information indicating the location of the UE 120 may include a measurement report. The measurement report may include a list of one or more cells determined by the UE 120 to be the strongest neighbor cells. In some aspects, the measurement report may include RSRP values ​​for the list of one or more cells. The one or more cells may include NTN cells, terrestrial network cells, or a combination thereof. For a more detailed description of the contents of the RAM, refer to Fig. 9 and 10 .

[0098] In some aspects, information indicating the location of UE 120 may be encoded, encrypted, protected, etc. For example, the identity of a cell or beam (e.g., a beam identifier, a virtual cell identifier, a physical cell identifier, etc.) may be protected or encoded based at least in part on a key. In some aspects, the key may be pre-configured at UE 120 (e.g., pre-configured as part of an initial setup procedure for UE 120, pre-configured by an original equipment manufacturer of UE 120, etc.). In some aspects, the key may be negotiated with a satellite or public land mobile network (PLMN) associated with UE 120. Thus, information about the location of the UE may be secured, which reduces the likelihood that the information may be compromised, e.g., for malicious purposes.

[0099] As indicated by reference numeral 630, BS 110 may determine whether to accept or reject a RACH procedure for UE 120 based at least in part on the location of the UE. For example, if the location of UE 120 is within an area associated with a core network of BS 110 (e.g., within an area associated with the same MCC as BS 110, etc.), BS 110 may determine to accept the RACH procedure. In some aspects, BS 110 may determine to reject the RACH procedure based at least in part on the location being outside an area associated with a core network of BS 110 (e.g., in an area associated with an MCC different from the MCC associated with BS 110). Additionally or alternatively, BS 110 may determine whether to accept or reject the RACH procedure based at least in part on compatibility determinations related to core networks of respective areas of BS 110 and UE 120, load balancing considerations, and the like.

[0100] In some aspects, the location may be determined by BS 110. For example, based at least in part on measurement information received from UE 120 in an RRC SETUP REQUEST message or another message, BS 110 may communicate with a location management function or component to determine the location and / or country of UE 120 based at least in part on the measurement information. The location management function may also provide configuration information for measurements to be performed by UE 120 to locate UE 120 and / or the country in which UE 120 is located. In some aspects, the location management function may be co-located with BS 110. In some aspects, the location management function may not be co-located with BS 110.

[0101] As indicated by reference numeral 635, BS 110 may transmit RACH msg4 to UE 120. If BS 110 accepts the RACH procedure, BS 110 may transmit an RRC connection setup message. If BS 110 rejects the RACH procedure, BS 110 may transmit an RRC reject message. In some aspects, the RRC reject message may indicate a cause associated with the RRC reject message. For example, the RRC reject message may indicate that the RACH procedure is rejected based at least in part on the location of UE 120. In some aspects, the RRC reject message may include a cause value indicating to UE 120 that a priority is to be lowered for cells or beams whose locations are indicated to BS 110 (e.g., one or more cells or beams identified as neighbor cells or beams). In such a case, UE 120 may lower the priority of the cells or beams associated with the RRC reject message. Thus, BS 110 may reduce the likelihood that UE 120 selects a cell associated with a different area than BS 110, thereby conserving network resources associated with cell selection.

[0102] As indicated above, Figure 6are provided as examples. Other examples may differ from those described herein. Figure 6 Examples described.

[0103] Figure 7 is a diagram illustrating an example 700 of signaling associated with location-based admission control for non-terrestrial networks in accordance with the present disclosure. Example 700 relates to an indication of a location associated with UE 120 in an RRC setup complete message, such as the fifth message associated with a four-step RACH procedure.

[0104] like Figure 7 1 and indicated by reference numeral 705, BS 110 may transmit and UE 120 may receive system information (eg, SIB). Figure 6 605 is described in more detail.

[0105] As further shown, BS 110 and UE 120 may perform a four-step RACH procedure in conjunction with Figure 4 In some aspects, BS 110 and UE 120 may perform a two-step RACH procedure in conjunction with Figure 5 As further shown, BS 110 and UE 120 may successfully complete the RACH procedure. For example, BS 110 may transmit an RRC connection setup message (eg, RAM msg4) to UE 120 to configure the RRC connection.

[0106] As indicated by reference numeral 710, UE 120 may determine the location of UE 120. The determination of the location of UE 120 may be combined with Figure 6 As shown by reference numeral 620, UE 120 may transmit an RRC connection setup complete message (referred to as msg5 of the four-step RACH procedure) including an indication of the location of UE 120. For example, the indication of the location of UE 120 may include a combination of Figure 6 In some aspects, the indication of the location of UE 120 may be encoded or protected, such as in conjunction with Figure 6 Described in more detail.

[0107] As indicated by reference numeral 720, BS 110 may determine whether to maintain an RRC connection with UE 120 based at least in part on the location. For example, BS 110 may determine whether to keep UE 120 in an RRC connected mode with BS 110, redirect UE 120 to another cell (e.g., an NTN cell or a terrestrial network cell), or trigger a handover to another cell. In some aspects, BS 110 may perform this determination based at least in part on a measurement report from UE 120. For example, if UE 120 provides information indicating the location of UE 120 in a measurement report, BS 110 may determine a target cell for handover based at least in part on the measurement report.

[0108] As indicated above, Figure 7 are provided as examples. Other examples may differ from those described herein. Figure 7 Examples described.

[0109] Figure 8 8 is a diagram illustrating an example 800 of beam switching based at least in part on the location of UE 120 according to the present disclosure. As shown, example 800 includes UE 120, source cell 805, and target cell 810. Source cell 805 may be an NTN cell (e.g., provided by a non-terrestrial wireless communication device) or a terrestrial network cell. Target cell 810 may be an NTN cell or a terrestrial network cell. Source cell 805 and target cell 810 may be provided by different BSs (e.g., BS 110) or the same BS (e.g., BS 110).

[0110] In example 800, information indicating the location of UE 120 is provided in an RRC SETUP REQUEST message, such as RACH Msg3, as indicated by reference numeral 815. In some aspects, information indicating the location of UE 120 may be provided in an RRC SETUP COMPLETE message. At the time when UE 120 transmits the information indicating the location of UE 120, UE 120 may not have been configured with application layer (AS) security (e.g., UE 120 may not have received a security mode command from source cell 805).

[0111] As indicated by reference numeral 820, the source cell 805 (e.g., a BS providing the source cell) may determine that the UE 120 should be handed over to the target cell 810. For example, the source cell 805 may perform the determination based at least in part on the location of the UE 120 and / or the measurement report provided by the UE 120. Accordingly, as indicated by reference numeral 825, the source cell 805 may forward the RRC setup request message to the target cell 810. As indicated by reference numeral 830, the target cell 810 may provide the RRC setup message and the handover command for the UE 120 to the source cell 805. As indicated by reference numeral 835, the source cell 805 may forward the RRC setup message and the handover command to the UE 120. In some aspects, if the RRC connection has been established (e.g., if the RACH procedure is complete), the target cell 810 may provide the RRC reconfiguration message to the UE 120 via the source cell 805. As indicated by reference numeral 840, the UE 120 may perform a contention-free random access channel (RACH) procedure with the target cell 810. As indicated by reference numeral 845, the UE 120 may transmit an RRC reconfiguration complete or RRC setup complete message to the target cell. If the UE 120 transmits the RRC reconfiguration complete message, the AS security and dedicated radio bearer (DRB) associated with the target cell 810 may not have been added for the connection between the UE 120 and the target cell 810.

[0112] Combination Figure 8 The described operations may also be applied to an RRC resumption procedure (eg, for a UE 120 that is in an RRC inactive state).

[0113] about Figure 6-8 Many of the operations described are described in the context of a four-step RACH procedure. However, these operations may also be performed for a two-step RACH procedure. For example, information indicating the location of UE 120 may be transmitted in RACH Msg3 or RACH MsgA, and a RAR associated with the information may be transmitted in RACH Msg4 or RACH MsgB.

[0114] Fig. 9 and 10 are diagrams illustrating examples 900 and 1000 of the structure of an RRC SETUP REQUEST message according to the present disclosure. Fig. 9An 80-bit 5G Global Unique Temporary Identifier (GUTI) 905 and a 48-bit 5G Service Architecture Evolution (SAE) Temporary Mobile Station Identifier (S-TMSI) are shown. As shown, the GUTI 905 includes a 12-bit MCC, a 12-bit Mobile Network Code (MNC), an 8-bit regional identifier, a 10-bit set identifier, a 6-bit set pointer to an access management function, and a 32-bit M-TMSI.

[0115] Reference numerals 915 and 920 show a first option (option 1) and a second option (option 2) for the structure of the RRC setup request message. As shown by reference numeral 925, option 1 and option 2 include an MCC indicating the location of UE 120. As shown by reference numeral 930, option 1 includes a portion of 5G-S-TMSI 910, such as a set identifier, a set pointer, and 10 bits of M-TMSI. The MCC and M-TMSI may indicate the location of UE 120. In this case, the remainder of 5G-S-TMSI 910 may be transmitted after the RACH procedure is completed. As shown by reference numeral 935, option 2 includes a set pointer and a larger portion of M-TMSI than option 1. For example, option 2 may include bits 11 to 36 of 5G-S-TMSI 910 from the left.

[0116] As indicated by reference numeral 940, option 1 and option 2 include a bit indicator. In some aspects, the bit indicator may indicate whether the MCC is included in the RRC setup request (e.g., whether the MCC field is set to be part of the registered PLMN of the UE 120). For example, a first value of the bit indicator may indicate that the MCC is not included in the RRC setup request message, and a second value of the bit indicator may indicate that the MCC is not included in the RRC setup request message. In some aspects, the bit indicator may indicate whether the rightmost 38 bits of the 5G-S-TMSI 910 are included in the RRC setup request message.

[0117] In some aspects, the RRC SETUP REQUEST message may include a random or pseudo-random value. The random or pseudo-random value may improve contention resolution by reducing the likelihood that two UEs transmit the same RRC SETUP REQUEST message. An example of the structure of an RRC SETUP REQUEST message incorporating a random or pseudo-random value is shown in Fig.10 As shown in Fig.10In and as shown by reference numeral 1010, when the bit indicator (e.g., bit indicator 94f0) is set to a first value, the RRC setup request message may not include an MCC or a random value. Reference numerals 1020 and 1030 show alternatives to the structure of the RRC setup request message. As shown by reference numeral 1020, in some aspects, when the bit indicator is set to a second value, the RRC setup request message may include the MCC (or a pointer to the MCC) and the rightmost 32 bits of the 5G-S-TMSI (e.g., 5G-S-TMSI 910). As shown by reference numeral 1030, in some aspects, when the bit indicator is set to a second value, the RRC setup request message may include the MCC or a pointer to the MCC, a random value (here an 8-bit random value, but other lengths may be used), and the rightmost 24 bits of the 5G-S-TMSI.

[0118] In some aspects, UE 120 may be configured with information indicating how to map the location of UE 120 to the MCC pointer. In some aspects, UE 120 may be configured with or may receive via broadcast information indicating whether to use a set pointer (e.g., as shown by reference numeral 1010) or an MCC (e.g., as shown by reference numeral 1020 / 1030) in the ng-5G-S-TMSI.

[0119] As indicated above, Fig. 9 and 10 are provided as examples. Other examples may differ from those described in Fig. 9 and 10 Examples described.
