The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, algorithm, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

Mobile communication has evolved significantly from early voice systems to today's highly sophisticated integrated communication platform. The next-generation wireless communication system, 5G, or new radio (NR) will provide access to information and sharing of data anywhere, anytime by various users and applications. NR is expected to be a unified network/system that targets to meet vastly different and sometimes conflicting performance dimensions and services. Such diverse multi-dimensional requirements are driven by different services and applications. In general, NR will evolve based on 3GPP LTE-Advanced with additional potential new Radio Access Technologies (RATs) to enrich people lives with better, simple and seamless wireless connectivity solutions. NR will enable everything connected by wireless and deliver fast, rich content and services.

For cellular systems, coverage is an important factor for successful operation. Compared to LTE, NR can be deployed at relatively higher carrier frequency in frequency range 1 (FR1), e.g., at 3.5GHz. In this case, coverage loss is expected due to larger path-loss, which makes it more challenging to maintain an adequate quality of service. Typically, uplink coverage is the bottleneck for system operation considering the low transmit power at UE side.

In NR, multiple transmit and receive points (TRPs) can be utilized to transmit and receive data and control channel, which can help in improving the reliability for communication. In order to utilize the multiple TRPs more efficiently, simultaneous transmission with multi-panel can be supported, where the UE is equipped with multiple antenna panels. In particular, to improve robustness of the transmission to potential blockage of the channel, UE could transmit data and control information targeting two or more TRPs simultaneously.

When UE is equipped with multiple panels, UE may transmit multiple Physical Random Access Channel (PRACH) using multiple panels simultaneously to improve reliability of PRACH detection. In this case, certain mechanisms may need to be defined for enhanced RACH procedure with multiple panels, which includes 4-step RACH and 2-step RACH procedure. A function of PRACH is to enable the UE to send a signal to the base station indicating its desire to initiate communication. This signal is known as a ' preamble." The base station then acknowledges this initial contact and allocates resources for further communication, facilitating a full connection establishment between the UE and the network.

Example embodiments of the present disclosure relate to systems, methods, and devices for mechanisms for enhanced random access procedure with multiple panels.

In one or more embodiments, an enhanced random access procedure may faciliate mechanisms involving multiple panels. This implies a significant advancement in wireless communication technology, potentially leading to faster and more reliable connections in networks.

In one or more embodiments, an enhanced random access procedure may facilitate multiple physical random access channel (PRACH) transmissions utilizing different transmission (Tx) beams. By using various Tx beams for PRACH transmissions, the system can adapt to different environmental conditions and user locations, enhancing signal coverage and quality.

Additionally, the enhanced random access procedure may facilitate power control channel (PDCCH) monitoring for the transmission of random access responses. Effective monitoring of the PDCCH can lead to more accurate and timely adjustments in power levels for random access responses, thus optimizing network performance under varying load conditions.

In one or more embodiments, an enhanced random access procedure may facilitate multiple Message 3 (Msg3) transmissions, each employing different Tx beams. In other words, The enhanced random access procedure is designed to effectively manage multiple instances of Msg3 transmissions in wireless communication. This system's capability to handle Msg3, a crucial step in the connection setup process initiated by user equipment, is enhanced by its use of different Transmit (Tx) beams for each transmission. Employing different Tx beams, a key feature in beamforming technology, allows the system to direct signals precisely towards intended users. This approach not only improves the efficiency of the network but also ensures more effective and targeted communication, especially vital in high-density environments or scenarios demanding high-precision signal direction.

These mechanisms collectively aim to improve the efficiency and reliability of the random access procedure in communication systems and improve NR PRACH coverage. Such improvements could result in reduced latency, increased throughput, and overall better user experience in next-generation wireless networks, such as 5G and beyond. The above descriptions are for purposes of illustration and are not meant to be limiting. Numerous other examples, configurations, processes, algorithms, etc., may exist, some of which are described in greater detail below. Example embodiments will now be described with reference to the accompanying figures.

FIG. 1 depicts an illustrative schematic diagram for enhanced random access, in accordance with one or more example embodiments of the present disclosure.

In NR Rel-I5, a 4-step procedure was defined. FIG. 1 illustrates the 4-step random access channel (RACK) procedure for initial access. In the first step, UE transmits transmits a signal on the PRACH in the uplink by randomly selecting one preamble signature, which would allow gNB to estimate the delay between gNB and UE for subsequent UL timing adjustment. This estimation is important as it ensures that the data sent from UE reaches gNB at the right time, maintaining network synchronization and efficiency. Subsequently, in the second step, gNB feedbacks the random access response (RAR) which carries timing advanced (TA) command information and uplink grant for the uplink transmission in the third step. The uplink grant in the RAR enables the UE to send data on the allocated uplink resources, thereby establishing a communication link. The UE expects to receive the RAR within a time window, of which the start and end are configured by the gNB via system information block (SIB).

In the first step of 4-step RACH procedure, a UE measures the reference signal received power (RSRP) from synchronization signal block (SSB) using a Rx beam and determines an SSB index with RSRP above a threshold. This RSRP measurement is important for the UE to assess the quality of the received signal and to select the best SSB for communication. Each SSB is associated with specific PRACH occasions, which are symbol index and/or time slots configured by the network for the UE's access using PRACH. Based on the association between SSB and PRACH occasion, the UE selects a PRACH occasion, referred to as random access occasion (RO), for PRACH transmission using the Tx beam corresponding to the selected SSB index. This selection of the RO, based on the SSB-PRACH association, is crucial as it ensures the chosen RO aligns with the SSB index providing the strongest signal quality. This selection is important for aligning the transmission beam with the gNB's reception beam, optimizing the signal strength and quality. When the UE has perfect beam correspondence where Tx beam and Rx beam are fully aligned, gNB may successfully detect PRACH preamble in the first step of 4-step RACH procedure. Perfect beam correspondence significantly enhances the chances of successful PRACH detection, leading to a more reliable and efficient initial access process. It should be noted that RACH is the broader procedure or set of steps that a device follows to initiate communication with a cellular network, while PRACH is a specific part of this procedure, representing the physical channel over which the initial access signal is sent.

It is understood that the above descriptions are for the purposes of illustration and are not meant to be limiting.

FIG. 2 depicts an illustrative schematic diagram for enhanced random access, in accordance with one or more example embodiments of the present disclosure.

In one or more embodiments, an enhanced random access procedure may facilitate multiple PRACH transmissions with different Tx beams.

As mentioned above, in NR, multiple transmit and receive points (TRPs) can be utilized to transmit and receive data and control channel, which can help in improving the reliability for communication. In order to utilize the multiple TRPs more efficiently, panels refer to distinct arrays of antennas in a device, each capable of directing signals in different directions. For example, a smartphone might have one panel on its top edge and another on its bottom edge, allowing it to send and receive signals in multiple directions simultaneously. Simultaneous transmission with multi-panel can be supported, where the UE is equipped with multiple antenna panels. In particular, to improve robustness of the transmission to potential blockage of the channel, UE could transmit data and control information targeting two or more TRPs simultaneously.

When a UE is equipped with multiple panels, the UE may transmit multiple PRACH using multiple panels simultaneously to improve reliability of PRACH detection. For instance, if a device has three panels, it could send a PRACH signal from each panel in different directions, increasing the likelihood that at least one signal reaches the intended receiver without interference or blockage. In this case, certain mechanisms may need to be defined for enhanced RACH procedure with multiple panels, which includes 4-step RACH and 2-step RACH procedure.

Embodiments of multiple PRACH transmissions with different Tx beams are provided as follows:

In one embodiment, when a UE is equipped with more than one panel, the UE may transmit multiple PRACH using different preambles in a same PRACH occasion, which is associated with a same or different synchronization signal block (SSB). In addition, preambles in multiple PRACH occasions may be same or different. In case when the preamble are different in multiple PRACH occasions, association between preambles in multiple PRACH occasions may be defined. In some aspects, to differentiate multiple PRACH transmissions using different beams which are associated with different SSBs and multiple PRACH transmissions which are associated with same SSB, either separate preambles in a shared PRACH occasion or separate PRACH occasions may be configured.

As a further extension, the above options can be applied to differentiate the case when UE transmits multiple PRACHs simultaneously using different panels.

In another embodiment, when a UE is equipped with more than one panels, the UE may transmit multiple PRACH using same or different preambles in different PRACH occasions, which is associated with a same or different synchronization signal block (SSB). In addition, preambles in multiple PRACH occasions may be same or different. In case when the preamble are different in multiple PRACH occasions, association between preambles in multiple PRACH occasions may be defined.

In one option, the PRACH occasions can be multiplexed in a frequency division multiplexing (FDM) manner. In this case, the UE may transmit multiple PRACHs in using different panels simultaneously. In some aspects, the PRACH occasions that are multiplexed in a FDM manner are associated with an SSB. This option may apply for the case when UE transmits the PRACH using narrow beams using multiple panels where gNB may use wide receive beam for PRACH detection.

In addition, when more than one PRACH occasions are multiplexed in a FDM manner, UE may select the PRACH occasions with distance which is determined based on the total number of FDM’ed PRACH occasions. For instance, if the total number of FDM’ed PRACH occasions is N, the distance between a first and second PRACH occasion for PRACH transmission using different panels can be [1V/2J or [7V/2 ] .

FIG. 2 illustrates one example of simultaneous PRACH transmissions in two FDM'ed PRACH occasions using two panels. In the example, SSB#0 is associated with 4 PRACH occasions that are multiplexed in a FDM manner. Further, UE transmits a first preamble using a first panel in a first PRACH occasion (RO#0) and a second preamble using a second panel in a second PRACH occasion (RO#2).

In another option, the PRACH occasions can be multiplexed in a time division multiplexing (TDM) manner. In this case, the UE may transmit multiple PRACHs in a TDM manner in using same panel or different panels.

FIG. 3 depicts an illustrative schematic diagram for enhanced random access, in accordance with one or more example embodiments of the present disclosure. FIG. 3 illustrates one example of PRACH transmissions in two TDM’ed PRACH occasions using two panels. In the example, each SSB is associated with one PRACH occasion, and different PRACH occasions are multiplexed in a TDM manner. Further, UE transmits a first preamble using a first panel in a first PRACH occasion (RO#0) and a second preamble using a second panel in a second PRACH occasion (RO#2).

In some aspects, the embodiments as mentioned above can apply for 4-step RACH and 2-step RACH procedure. Further, the embodiments mentioned above can apply for MsgA physical uplink shared channel (PUSCH) transmission.

In one or more embodiments, an enhanced random access procedure may facilitate PDCCH monitoring for random access response transmission

Embodiments of PDCCH monitoring for random access response (RAR) transmission are provided as follows:

In one embodiment, separate control resource set (CORESET) may be configured for UE to monitor Typel-PDCCH Common Search Space (CSS) set for a DCI format with CRC scrambled by RA-RNTI. In particular, UE may assume that the DM-RS antenna port associated with PDCCH receptions in a first CORESET, and a first SS/PBCH block associated with a first PRACH transmission are quasi co-located with respect to average gain, QCL-TypeA, and QCL-TypeD properties. In addition, UE may assume that the DM-RS antenna port associated with PDCCH receptions in a second CORESET. and a second SS/PBCH block associated with a second PRACH transmission are quasi co-located with respect to average gain, QCL-TypeA, and QCL-TypeD properties.

FIG. 4 illustrates one example of two CORESETs for RAR monitoring. In the example, a first CORESET is used for RAR monitoring associated with the first PRACH transmission, while a second CORESET is used for RAR monitoring associated with the second RPACH transmission.

In another embodiment, separate search space for Typel-PDCCH CSS set by ra- SearchSpacel and ra-SearchSpace2 in PDCCH-ConfigCommon for a DCI format with CRC scrambled by RA-RNTI may be configured. For these two search space, UE may assume that the DM-RS antenna port associated with PDCCH receptions in the CORESET with the first RA search space, and the first SS/PBCH block associated with the first PRACH transmission are quasi co-located with respect to average gain, QCL-TypeA, and QCL-TypeD properties; Similarly, UE may assume that the DM-RS antenna port associated with PDCCH receptions in the CORESET with the second RA search space, and the second SS/PBCH block associated with the second PRACH transmission are quasi co-located with respect to average gain, QCL- TypeA, and QCL-TypeD properties.

In another embodiment, for physical downlink control channel (PDCCH) order PRACH transmission, multiple PRACH transmissions with different Tx beams are associated with different SSB, which are explicitly indicated in the DCI.

In one option, a second SSB index may be included in the DCI. which may be used to determine the second PRACH occasion for PRACH transmission. In addition, a second PRACH Mask index may be included in the DCI which may be used to indicate RACH occasion associated with the SS/PBCH indicated by the second SSB index for the PRACH transmission.

In one example implementation of embodiments herein, the following text in Section 7.3.1.2.1 of 3GPP TS 38.212 [1] can be updated as indicated with underline.

In another option, a second SSB index may be included in the DCI, which may be used to determine the second PRACH occasion for PRACH transmission. In this case, a common PRACH Mask index may be included in the DCI which may be used to indicate RACH occasion associated with the SS/PBCH indicated by both the first and second SSB index for the PRACH transmission.

In one example implementation, if the CRC of the DCI format 1 0 is scrambled by C- RNTI and the ‘"Frequency domain resource assignment” field are all ones, the DCI format 1 0 is for random access procedure initiated by a PDCCH order, with all remaining fields set as follows:

Reserved bits - 6 bits for operation in a cell with shared spectrum channel access; otherwise, 4 bits.

In one or more embodiments, an enhanced random access procedure may facilitate multiple Msg3 transmissions with different Tx beams.

Embodiments of multiple Msg3 transmissions with different Tx beams are further described below. In one embodiment, a UE may transmit multiple Msg3 PUSCH using different panels in a same or different time instance, where each Msg3 PUSCH is triggered by one random access response (RAR). In this case, the UE may transmit a first Msg3 PUSCH using the same Tx beam as a first PRACH transmission using a first panel, while transmit a second Msg3 PUSCH using the same Tx beam as a second PRACH transmission using a second panel.

In another embodiment, a UE may transmit multiple Msg3 PUSCH using different panels in a same or different time instance, where multiple Msg3 PUSCHs are triggered by an RAR UL grant.

In one option, multiple Msg3 PUSCH are transmitted in the same time and frequency resource using more than one panels. In this case, UE may transmit a first Msg3 PUSCH using the same Tx beam as a first PRACH transmission using a first panel, while transmit a second Msg3 PUSCH using the same Tx beam as a second PRACH transmission using a second panel.

FIG. 5 depicts an illustrative schematic diagram for enhanced random access, in accordance with one or more example embodiments of the present disclosure.

FIG. 5 illustrates one example of simultaneous Msg3 PUSCH transmission using two panels in the same time and frequency resource. In the example, Msg3 PUSCH transmissions for these two panels are allocated with same time and frequency resource in a Single Frequency Network (SFN) manner.

In another option, multiple Msg3 PUSCH are transmitted in the different time and/or frequency resource using more than one panels. In one example, multiple Msg3 PUSCH are transmitted in the different time instance, but with same frequency resource using more than one panels. In this case, a second time domain resource allocation field may be included in the RAR UL grant. In particular, a first time domain resource allocation field is used to indicate the time domain resource for a first Msg3 PUSCH transmission, while the second time domain resource allocation field may be used to indicate the time domain resource for a second Msg3 PUSCH transmission.

As a further extension, same start and length indicator value (SLIV) can be applied for the first and second Msg3 transmission, while different scheduling delays may be indicated for the first and second Msg3 transmission, respectively.

FIG. 6 depicts an illustrative schematic diagram for enhanced random access, in accordance with one or more example embodiments of the present disclosure.

FIG. 6 illustrates one example of multiple Msg3 PUSCH transmissions in different slots. In the example, a first Msg3 PUSCH using a first panel is transmitted in the first slot (slot#0), while a second Msg3 PUSCH using a second panel is transmited in the second slot (slot #3).

In another option, multiple Msg3 PUSCH are transmitted in the different frequency resource using more than one panels, and in the same time resource. In this case, a first frequency domain resource allocation field may be included in the RAR UL grant, which is used to indicate the frequency resource for a first Msg3 transmission. Further, a frequency offset may be configured by higher layers or explicitly indicated in the RAR UL grant, which is used to indicate the difference between the starting physical resource block (PRB) of the first and second Msg3 PUSCH transmission. As a further example, multiple Msg3 PUSCH transmissions may be allocated with contiguous frequency resources. In this case, gap between two adjacent Msg3 PUSCH is 0.

In the example, Msg3 PUSCH transmissions for these two panels are allocated with same time but different frequency resources. Further, a first Msg3 PUSCH using a first panel is transmited in the first frequency resource, while a second Msg3 PUSCH using a second panel is transmited in the second frequency resource.

In one or more embodiments, the device may be associated with a system and/or amethod of wireless communication for a 5G or NR system. This device may enable a UE to transmit more than one PRACH using multiple panels or transmit beams. In scenarios where a UE is equipped with multiple panels, it may transmit multiple PRACHs using different preambles in the same PRACH occasion, which could be associated with either the same or different SSBs. Furthermore, the device may differentiate between multiple PRACH transmissions using distinct beams associated with different SSBs and those associated with the same SSB by either configuring separate preambles in a shared PRACH occasion or seting up separate PRACH occasions.

Additionally, in one or more embodiments, the UE may transmit multiple PRACHs using the same or different preambles in different PRACH occasions, which again are associated with either the same or different SSBs. The PRACH occasions in this device may be multiplexed in an FDM manner, and when multiple PRACH occasions are multiplexed this way, the UE may select the PRACH occasions based on the distance determined by the total number of FDNTed PRACH occasions. Alternatively, PRACH occasions can be multiplexed in a TDM manner. The device may also be configured to have a separate CORESET for the UE to monitor Typel-PDCCH CSS set for a DCI format with CRC scrambled by RA-RNTI. It may include a separate search space for Typel-PDCCH CSS set by ra-SearchSpacel and ra-SearchSpace2 in PDCCH-ConfigCommon for a similar DCI format. For PDCCH order PRACH transmission, multiple PRACH transmissions with different Tx beams associated with different SSBs can be explicitly indicated in the DCI.

In one or more embodiments, the device may include a second SSB index in the DCI. which is used to determine the second PRACH occasion for PRACH transmission. Furthermore, the UE may transmit multiple Msg3 PUSCH using different panels in the same or different time instances, where each Msg3 PUSCH is triggered by one RAR or multiple Msg3 PUSCHs are triggered by an RAR UL grant. These Msg3 PUSCHs could be transmitted either in the same time and frequency resource or in different time instances but with the same frequency resource using more than one panel.

Moreover, the same SLIV can be applied for the first and second Msg3 transmission, while different scheduling delays may be indicated for each. The device may also enable the transmission of multiple Msg3 PUSCH in different frequency resources using more than one panel, and in the same time resource. Lastly, a frequency offset might be configured by higher layers or explicitly indicated in the RAR UL grant, which indicates the difference between the starting PRB of the first and second Msg3 PUSCH transmission.

In some embodiments, the electronic device(s), network(s), system(s), chip(s) or component(s), or portions or implementations thereof, of FIGs. 9-12, or some other figure herein, may be configured to perform one or more processes, techniques, or methods as described herein, or portions thereof. One such process is depicted in FIG. 8.

For example, the process may include, at 802, transmitting a plurality of physical random access channels (PRACH) utilizing a multi-panel configuration.

The process further includes, at 804, executing transmissions across various PRACH occasions employing same or different preambles.

The process further includes, at 806, differentiating PRACH transmissions based on their associations with synchronization signal block (SSB).

For one or more embodiments, at least one of the components set forth in one or more of the preceding figures may be configured to perform one or more operations, techniques, processes, and/or methods as set forth in the example section below. For example, the baseband circuitry as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below. For another example, circuitry associated with a UE, base station, network element, etc. as described above in connection with one or more of the preceding figures may be configured to operate in accordance with one or more of the examples set forth below in the example section.

It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

FIGs. Error! Reference source not found.-12 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.

FIG. 9 illustrates an example network architecture 900 according to various embodiments. The network 900 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems, or the like.

The network 900 includes a UE 902, which is any mobile or non-mobile computing device designed to communicate with a RAN 904 via an over-the-air connection. The UE 902 is communicatively coupled with the RAN 904 by a Uu interface, which may be applicable to both LTE and NR systems. Examples of the UE 902 include, but are not limited to, a smartphone, tablet computer, wearable computer, desktop computer, laptop computer, in- vehicle infotainment system, in-car entertainment system, instrument cluster, head-up display (HUD) device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electron! c/engine control unit, electronic/ engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, machine-to-machine (M2M), device-to-device (D2D), machine-type communication (MTC) device, Internet of Things (loT) device, and/or the like. The network 900 may include a plurality of UEs 902 coupled directly with one another via a D2D, ProSe, PC5, and/or sidelink (SL) interface. These UEs 902 may be M2M/D2D/MTC/IoT devices and/or vehicular systems that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc. The UE 902 may perform blind decoding attempts of SL channels/links according to the various embodiments herein.

In some embodiments, the UE 902 may additionally communicate with an AP 906 via an over-the-air (OTA) connection. The AP 906 manages a WLAN connection, which may serve to offload some/all network traffic from the RAN 904. The connection between the UE 902 and the AP 906 may be consistent with any IEEE 802. 11 protocol. Additionally, the UE 902, RAN 904, and AP 906 may utilize cellular- WLAN aggregation/integration (e.g., LWA/LWIP). Cellular- WLAN aggregation may involve the UE 902 being configured by the RAN 904 to utilize both cellular radio resources and WLAN resources.

The RAN 904 includes one or more access network nodes (ANs) 908. The ANs 908 terminate air-interface(s) for the UE 902 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and PHY/L1 protocols. In this manner, the AN 908 enables data/voice connectivity between CN 920 and the UE 902. The ANs 908 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells; or some combination thereof. In these implementations, an AN 908 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB. RSU, TRxP, etc.

One example implementation is a “CU/DU split” architecture where the ANs 908 are embodied as a gNB-Central Unit (CU) that is communicatively coupled with one or more gNB- Distributed Units (DUs), where each DU may be communicatively coupled with one or more Radio Units (RUs) (also referred to as RRHs, RRUs. or the like) (see e g., 3GPP TS 38.401 V16.1.0 (2020-03)). In some implementations, the one or more RUs may be individual RSUs. In some implementations, the CU/DU split may include an ng-eNB-CU and one or more ng- eNB-DUs instead of, or in addition to, the gNB-CU and gNB-DUs, respectively. The ANs 908 employed as the CU may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network including a virtual Base Band Unit (BBU) or BBU pool, cloud RAN (CRAN). Radio Equipment Controller (REC), Radio Cloud Center (RCC), centralized RAN (C-RAN), virtualized RAN (vRAN), and/or the like (although these terms may refer to different implementation concepts). Any other ty pe of architectures, arrangements, and/or configurations can be used.

The plurality of ANs may be coupled with one another via an X2 interface (if the RAN 904 is an LTE RAN or Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 910) or an Xn interface (if the RAN 904 is a NG-RAN 914). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow' the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc.

The ANs of the RAN 904 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 902 with an air interface for netw ork access. The UE 902 may be simultaneously connected with a plurality of cells provided by the same or different ANs 908 of the RAN 904. For example, the UE 902 and RAN 904 may use carrier aggregation to allow' the UE 902 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN 908 may be a master node that provides an MCG and a second AN 908 may be secondary node that provides an SCG. The first/second ANs 908 may be any combination of eNB, gNB, ng-eNB, etc.

The RAN 904 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/camer-sensing operations based on. for example, a listen-before-talk (LBT) protocol.

In V2X scenarios the UE 902 or AN 908 may be or act as a roadside unit (RSU), which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary’ (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very' low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular/WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network.

In some embodiments, the RAN 904 may be an E-UTRAN 910 with one or more eNBs 912. The an E-UTRAN 910 provides an LTE air interface (Uu) with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on C SIRS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands.

In some embodiments, the RAN 904 may be an next generation (NG)-RAN 914 with one or more gNB 916 and/or on or more ng-eNB 918. The gNB 916 connects with 5G-enabled UEs 902 using a 5G NR interface. The gNB 916 connects with a 5GC 940 through an NG interface, which includes an N2 interface or an N3 interface. The ng-eNB 918 also connects with the 5GC 940 through an NG interface, but may connect with a UE 902 via the Uu interface. The gNB 916 and the ng-eNB 918 may connect with each other over an Xn interface.

In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 914 and a UPF 948 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN 914 and an AMF 944 (e.g., N2 interface).

The NG-RAN 914 may provide a 5G-NR air interface (which may also be referred to as a Uu interface) with the following characteristics: variable SCS; CP-OFDM for DL, CP- OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G-NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH.

The 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 902 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 902, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 902 with different amount of frequency resources (e.g., PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 902 and in some cases at the gNB 91 . A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.

The RAN 904 is communicatively coupled to CN 920 that includes network elements and/or network functions (NFs) to provide various functions to support data and telecommunications services to customers/subscribers (e.g., UE 902). The components of the CN 920 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 920 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 920 may be referred to as a network slice, and a logical instantiation of a portion of the CN 920 may be referred to as a network sub-slice.

The CN 920 may be an LTE CN 922 (also referred to as an Evolved Packet Core (EPC) 922). The EPC 922 may include MME 924, SGW 926, SGSN 928, HSS 930, PGW 932, and PCRF 934 coupled with one another over interfaces (or “reference points”) as shown. The NFs in the EPC 922 are briefly introduced as follows.

The MME 924 implements mobility management functions to track a current location of the UE 902 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.

The SGW 926 terminates an SI interface toward the RAN 910 and routes data packets between the RAN 910 and the EPC 922. The SGW 926 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3 GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.

The SGSN 928 tracks a location of the UE 902 and performs security functions and access control. The SGSN 928 also performs inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 924; MME 924 selection for handovers; etc. The S3 reference point between the MME 924 and the SGSN 928 enable user and bearer information exchange for inter-3GPP access network mobility in idle/active states.

The HSS 930 includes a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 930 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 930 and the MME 924 may enable transfer of subscription and authentication data for authenticating/ authorizing user access to the EPC 920.

The PGW 932 may terminate an SGi interface toward a data network (DN) 936 that may include an application (app)Zcontent server 938. The PGW 932 routes data packets between the EPC 922 and the data network 936. The PGW 932 is communicatively coupled with the SGW 926 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 932 may further include a node for policy enforcement and charging data collection (e.g., PCEF). Additionally, the SGi reference point may communicatively couple the PGW 932 with the same or different data network 936. The PGW 932 may be communicatively coupled with a PCRF 934 via a Gx reference point. The PCRF 934 is the policy and charging control element of the EPC 922. The PCRF 934 is communicatively coupled to the app/content server 938 to determine appropriate QoS and charging parameters for service flows. The PCRF 932 also provisions associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.

The CN 920 may be a 5GC 940 including an AUSF 942, AMF 944, SMF 946, UPF 948, NSSF 950, NEF 952, NRF 954, PCF 956, UDM 958. and AF 960 coupled with one another over various interfaces as shown. The NFs in the 5GC 940 are briefly introduced as follows.

The AUSF 942 stores data for authentication of UE 902 and handle authentication- related functionality. The AUSF 942 may facilitate a common authentication framework for various access types..

The AMF 944 allows other functions of the 5GC 940 to communicate with the UE 902 and the RAN 904 and to subscribe to notifications about mobility events with respect to the UE 902. The AMF 944 is also responsible for registration management (e.g., for registering UE 902), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authonzation. The AMF 944 provides transport for SM messages between the UE 902 and the SMF 946, and acts as a transparent proxy for routing SM messages. AMF 944 also provides transport for SMS messages between UE 902 and an SMSF. AMF 944 interacts with the AUSF 942 and the UE 902 to perform various security anchor and context management functions. Furthermore, AMF 944 is a termination point of a RAN-CP interface, which includes the N2 reference point between the RAN 904 and the AMF 944. The AMF 944 is also a termination point of NAS (Nl) signaling, and performs NAS ciphering and integrity protection.

AMF 944 also supports NAS signaling with the UE 902 over an N3IWF interface. The N3IWF provides access to untrusted entities. N3IWF may be a termination point for the N2 interface between the (R)AN 904 and the AMF 944 for the control plane, and may be a termination point for the N3 reference point between the (R)AN 914 and the 948 for the user plane. As such, the AMF 944 handles N2 signalling from the SMF 946 and the AMF 944 for PDU sessions and QoS, encapsulate/de-encapsulate packets for IPSec andN3 tunnelling, marks N3 user-plane packets in the uplink, and enforces QoS corresponding to N3 packet marking taking into account QoS requirements associated with such marking received overN2. N3IWF may also relay UL and DL control-plane NAS signalling between the UE 902 and AMF 944 via an N 1 reference point between the UE 902and the AMF 944. and relay uplink and downlink user-plane packets between the UE 902 and UPF 948. The N3IWF also provides mechanisms for IPsec tunnel establishment with the UE 902. The AMF 944 may exhibit an Namf servicebased interface, and may be a termination point for an N14 reference point between two AMFs 944 and an N 17 reference point between the AMF 944 and a 5G-EIR (not shown by FIG. 9).

The SMF 946 is responsible for SM (e.g., session establishment, tunnel management between UPF 948 and AN 908); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 948 to route traffic to proper destination: termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification: initiating AN specific SM information, sent via AMF 944 over N2 to AN 908: and determining SSC mode of a session. SM refers to management of a PDU session, and a PDU session or “session” refers to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 902 and the DN 936.

The UPF 948 acts as an anchor point for intra-RAT and inter-RAT mobility⁷, an external PDU session point of interconnect to data netw ork 936, and a branching point to support multihomed PDU session. The UPF 948 also performs packet routing and forwarding, packet inspection, enforces user plane part of policy rules, lawfully intercept packets (UP collection), performs traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), performs uplink traffic verification (e.g., SDF-to-QoS flow mapping), transport level packet marking in the uplink and downlink, and performs downlink packet buffering and downlink data notification triggering. UPF 948 may include an uplink classifier to support routing traffic flow s to a data network.

The NSSF 950 selects a set of network slice instances serving the UE 902. The NSSF 950 also determines allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 950 also determines an AMF set to be used to serve the UE 902, or a list of candidate AMFs 944 based on a suitable configuration and possibly by querying the NRF 954. The selection of a set of network slice instances for the UE 902 may be triggered by the AMF 944 with which the UE 902 is registered by interacting with the NSSF 950; this may lead to a change of AMF 944. The NSSF 950 interacts with the AMF 944 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown).

The NEF 952 securely exposes services and capabilities provided by 3GPP NFs for third party, internal exposure/re-exposure, AFs 960, edge computing or fog computing systems (e.g., edge compute node, etc. In such embodiments, the NEF 952 may authenticate, authorize, or throtle the AFs. NEF 952 may also translate information exchanged with the AF 960 and information exchanged with internal network functions. For example, the NEF 952 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 952 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 952 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 952 to other NFs and AFs, or used for other purposes such as analytics.

The NRF 954 supports service discovery functions, receives NF discovery requests from NF instances, and provides information of the discovered NF instances to the requesting NF instances. NRF 954 also maintains information of available NF instances and their supported services. The NRF 954 also supports service discovery functions, wherein the NRF 954 receives NF Discovery Request from NF instance or an SCP (not shown), and provides information of the discovered NF instances to the NF instance or SCP.

The PCF 956 provides policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 956 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 958. In addition to communicating with functions over reference points as shown, the PCF 956 exhibit an Npcf sendee-based interface.

The UDM 958 handles subscription-related information to support the network entities’ handling of communication sessions, and stores subscription data of UE 902. For example, subscription data may be communicated via an N8 reference point between the UDM 958 and the AMF 944. The UDM 958 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 958 and the PCF 956. and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 902) for the NEF 952. The Nudr servicebased interface may be exhibited by the UDR 221 to allow the UDM 958, PCF 956, and NEF 952 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM-FE. which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 958 may exhibit the Nudm service-based interface.

AF 960 provides application influence on traffic routing, provide access to NEF 952, and interact with the policy framework for policy control. The AF 960 may influence UPF 948 (re)selection and traffic routing. Based on operator deployment, when AF 960 is considered to be a trusted entity, the network operator may permit AF 960 to interact directly with relevant NFs. Additionally, the AF 960 may be used for edge computing implementations,

The 5GC 940 may enable edge computing by selecting operator/3rd party services to be geographically close to a point that the UE 902 is attached to the network. This may reduce latency and load on the network. In edge computing implementations, the 5GC 940 may select a UPF 948 close to the UE 902 and execute traffic steering from the UPF 948 to DN 936 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 960, which allows the AF 960 to influence UPF (re)selection and traffic routing.

The data network (DN) 936 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application (app)/content server 938. The DN 936 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. In this embodiment, the app server 938 can be coupled to an IMS via an S-CSCF or the I-CSCF. In some implementations, the DN 936 may represent one or more local area DNs (LADNs), which are DNs 936 (or DN names (DNNs)) that is/are accessible by a UE 902 in one or more specific areas. Outside of these specific areas, the UE 902 is not able to access the LADN/DN 936.

Additionally or alternatively, the DN 936 may be an Edge DN 936, which is a (local) Data Network that supports the architecture for enabling edge applications. In these embodiments, the app server 938 may represent the physical hardware systems/devices providing app server functionality and/or the application software resident in the cloud or at an edge compute node that performs server function(s). In some embodiments, the app/content server 938 provides an edge hosting environment that provides support required for Edge Application Server’s execution.

In some embodiments, the 5GS can use one or more edge compute nodes to provide an interface and offload processing of wireless communication traffic. In these embodiments, the edge compute nodes may be included in, or co-located with one or more RAN910. 914. For example, the edge compute nodes can provide a connection between the RAN 914 and UPF 948 in the 5GC 940. The edge compute nodes can use one or more NFV instances instantiated on virtualization infrastructure within the edge compute nodes to process wireless connections to and from the RAN 914 and UPF 948.

The interfaces of the 5GC 940 include reference points and service-based itnterfaces. The reference points include: N 1 (between the UE 902 and the AMF 944), N2 (between RAN 914 and AMF 944), N3 (between RAN 914 and UPF 948), N4 (between the SMF 946 and UPF 948). N5 (between PCF 956 and AF 960), N6 (between UPF 948 and DN 936), N7 (between SMF 946 and PCF 956), N8 (between UDM 958 and AMF 944), N9 (between two UPFs 948), N10 (between the UDM 958 and the SMF 946), Ni l (between the AMF 944 and the SMF 946), N12 (between AUSF 942 and AMF 944), N13 (between AUSF 942 and UDM 958). N14 (between two AMFs 944; not shown), N15 (between PCF 956 and AMF 944 in case of a nonroaming scenario, or between the PCF 956 in a visited network and AMF 944 in case of a roaming scenario), N16 (between two SMFs 946; not shown), and N22 (between AMF 944 and NSSF 950). Other reference point representations not shown in FIG. 9 can also be used. The service-based representation of FIG. 9 represents NFs within the control plane that enable other authorized NFs to access their services. The service-based interfaces (SBIs) include: Namf (SBI exhibited by AMF 944), Nsrnf (SBI exhibited by SMF 946), Nnef (SBI exhibited by NEF 952), Npcf (SBI exhibited by PCF 956), Nudm (SBI exhibited by the UDM 958), Naf (SBI exhibited by AF 960), Nnrf (SBI exhibited by NRF 954), Nnssf (SBI exhibited by NSSF 950). Nausf (SBI exhibited by AUSF 942). Other service-based interfaces (e.g.. Nudr, N5g-eir, and Nudsf) not shown in FIG. 9 can also be used. In some embodiments, the NEF 952 can provide an interface to edge compute nodes 936x, which can be used to process wireless connections with the RAN 914.1n some implementations, the system 900 may include an SMSF. which is responsible for SMS subscription checking and verification, and relaying SM messages to/from the UE 902 to/from other entities, such as an SMS-GMSC/IWMSC/SMS- router. The SMS may also interact with AMF 944 and UDM 958 for a notification procedure that the UE 902 is available for SMS transfer (e.g., set a UE not reachable flag, and notifying UDM 958 when UE 902 is available for SMS).

The 5GS may also include an SCP (or individual instances of the SCP) that supports indirect communication (see e.g., 3GPP TS 23.501 section 7.1.1); delegated discovery (see e.g., 3GPP TS 23.501 section 7.1.1); message forwarding and routing to destination NF/NF service(s), communication security (e.g., authorization of the NF Service Consumer to access the NF Service Producer API) (see e.g., 3GPP TS 33.501), load balancing, monitoring, overload control, etc.; and discovery and selection functionality forUDM(s), AUSF(s), UDR(s), PCF(s) with access to subscription data stored in the UDR based on UE' s SUPI. SUCI or GPSI (see e.g., 3GPP TS 23.501 section 6.3). Load balancing, monitoring, overload control functionality provided by the SCP may be implementation specific. The SCP may be deployed in a distributed manner. More than one SCP can be present in the communication path between various NF Services. The SCP, although not an NF instance, can also be deployed distributed, redundant, and scalable.
