     TECHNICAL FIELD 
     This disclosure relates generally to facilitating failure recovery of a beam. For example, this disclosure relates to facilitating signaling and channels for a beam identification and recovery request transmission for a 5G or other next generation network. 
     BACKGROUND 
     5 th  generation (5G) wireless systems represent a next major phase of mobile telecommunications standards beyond the current telecommunications standards of 4 th  generation (4G). Rather than faster peak Internet connection speeds, 5G planning aims at higher capacity than current 4G, allowing a higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities. This would enable a large portion of the population to stream high-definition media many hours per day with their mobile devices, when out of reach of wireless fidelity hotspots. 5G research and development also aims at improved support of machine-to-machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption, and lower latency than 4G equipment. 
     The above-described background relating to facilitating signaling and channels for new beam identification and recovery request transmission is merely intended to provide a contextual overview of some current issues, and is not intended to be exhaustive. Other contextual information may become further apparent upon review of the following detailed description.

     It should be noted that although various aspects and embodiments have been described herein in the context of 5G, Universal Mobile Telecommunications System (UMTS), and/or Long Term Evolution (LTE), or other next generation networks, the disclosed aspects are not limited to 5G, a UMTS implementation, and/or an LTE implementation as the techniques can also be applied in 3G, 4G or LTE systems. For example, aspects or features of the disclosed embodiments can be exploited in substantially any wireless communication technology. Such wireless communication technologies can include UMTS, Code Division Multiple Access (CDMA), Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), General Packet Radio Service (GPRS), Enhanced GPRS, Third Generation Partnership Project (3GPP), LTE, Third Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB), High Speed Packet Access (HSPA), Evolved High Speed Packet Access (HSPA+), High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), Zigbee, or another IEEE 802.XX technology. Additionally, substantially all aspects disclosed herein can be exploited in legacy telecommunication technologies. 
     Described herein are systems, methods, articles of manufacture, and other embodiments or implementations that can facilitate beam recovery for a 5G network. Facilitating beam recovery for a 5G network can be implemented in connection with any type of device with a connection to the communications network (e.g., a mobile handset, a computer, a handheld device, etc.) any Internet of things (JOT) device (e.g., toaster, coffee maker, blinds, music players, speakers, etc.), and/or any connected vehicles (cars, airplanes, space rockets, and/or other at least partially automated vehicles (e.g., drones)). In some embodiments the non-limiting term user equipment (UE) is used. It can refer to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. Note that the terms element, elements and antenna ports can be interchangeably used but carry the same meaning in this disclosure. The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. 
     In some embodiments the non-limiting term radio network node or simply network node is used. It can refer to any type of network node that serves UE is connected to other network nodes or network elements or any radio node from where UE receives a signal. Examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, eNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc. 
     Cloud radio access networks (RAN) can enable the implementation of concepts such as software-defined network (SDN) and network function virtualization (NFV) in 5G networks. This disclosure can facilitate a generic channel state information framework design for a 5G network. Certain embodiments of this disclosure can comprise an SDN controller that can control routing of traffic within the network and between the network and traffic destinations. The SDN controller can be merged with the 5G network architecture to enable service deliveries via open application programming interfaces (“APIs”) and move the network core towards an all internet protocol (“IP”), cloud based, and software driven telecommunications network. The SDN controller can work with, or take the place of policy and charging rules function (“PCRF”) network elements so that policies such as quality of service and traffic management and routing can be synchronized and managed end to end. 
     To meet the huge demand for data centric applications, 4G standards can be applied 5G, also called new radio (NR) access. 5G networks can comprise the following: data rates of several tens of megabits per second supported for tens of thousands of users; 1 gigabit per second can be offered simultaneously to tens of workers on the same office floor; several hundreds of thousands of simultaneous connections can be supported for massive sensor deployments; spectral efficiency can be enhanced compared to 4G; improved coverage; enhanced signaling efficiency; and reduced latency compared to LTE. In multicarrier system such as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrier spacing). If the carriers use the same bandwidth spacing, then it can be considered a single numerology. However, if the carriers occupy different bandwidth and/or spacing, then it can be considered a multiple numerology. 
     Downlink reference signals are predefined signals occupying specific resource elements within a downlink time-frequency grid. There are several types of downlink reference signals that can be transmitted in different ways and used for different purposes by a receiving terminal. Channel state information reference signals (CSI-RS) can be used by terminals to acquire channel-state information (CSI) and beam specific information (e.g., beam reference signal received power). In 5G, CSI-RS can be user equipment (UE) specific so it can have a significantly lower time/frequency density. Demodulation reference signals (DM-RS), also sometimes referred to as UE-specific reference signals, can be used by terminals for channel estimation of data channels. The label “UE-specific” relates to the demodulation reference signal being intended for channel estimation by a single terminal. The demodulation reference signal can then be transmitted within the resource blocks assigned for data traffic channel transmission to that terminal. Other than the aforementioned reference signals, there are other reference signals, namely multi-cast broadcast single frequency network (MBSFN) and positioning reference signals that can be used for various purposes. 
     Beam recovery procedure is clear for a single beam pair link (BPL), where a beam pair link is a pair of a DL Tx beam and an UL Rx beam. The BPL quality can be estimated by the associated RS resource. Therefore the failure of the RS resource represents the beam failure. However, a UE can be configured with multiple sets of BPLs. Each set of BPL(s) can be associated with one RS resource. 
     After beam failure detection, the UE can try to identify a new candidate beam to be used for beam recovery. To identify a new candidate beam, the UE can monitor the beam identification RS. This RS can be CSI-RS, used for beam management, if it is configured by the network. In the case when CSI-RS is not configured, or when the configured set of CSI-RS cannot be used to identify a new beam, another RS can be used to do new beam identification. 
     After new beam identification, the UE can send a beam recovery request transmission. Information carried by the beam recovery request transmission can include, but is not limited to, information about identifying UE and new network node (e.g., gNB) TX beam information. The channels that carry the beam recovery request transmissions can be similar to a non-contention physical random access channel (PRACH) based on PRACH, which uses resources orthogonal to resources of other PRACH transmissions. 
     In addition to non-contention based PRACH, other channels for recovery request transmissions can also potentially be used, such as contention-based RACH resources. A straightforward way is to use the 4-step RACH procedure, similar to the one used in initial access, is with preambles chosen from the traditional RACH resource pool. 
     During a beam failure recovery procedure, after beam failure detection, the UE can monitor the beam identification reference signal (RS), to identify new beams for recovery. A beam failure can be detected when the UE is not able to receive any signal data detecting that the beam is working. Beam identification RSs can be UE-specific channel state information-reference signal (CSI-RS), used for beam management, if configured for the UE. When configured, the CSI-RS can be used to identify new beams. If the CSI-RS based monitoring fails to identify a new beam, and no other RS is used for beam management, the UE cannot identify the new beam in the current example. This can result in either a recovery signaling to the network to inform the network of no new candidate beam exists, or a declaration of beam failure. 
     However, use of a synchronization signaling (SS) block, as another RS used for new beam identification, can be implemented in a 2-step approach for new beam identification. Existing solutions for beam recovery request transmission can use non-contention based random access channel (RACH) type resources to inform the network of the identified new beam and the occurrence of the beam failure. These resources might not be sufficient when another RS, other than the configured CSI-RS is used for new beam identification, such as SS-block. Instead of using the traditional 4-step RACH procedure for beam recovery request transmission, this disclosure discusses a modified 2-step contention-based RACH procedure that preserves overhead and reduces latency associated with the traditional 4-step procedure. 
     RACH resources can comprise preambles (e.g., unique UE identifiers) that are already configured to a specific UE. The preambles can allow the system to operate as a non contention-based system, wherein the UE can send the network device a preamble to assist in identification of the UE, thereby preserving resources. However, in a non-contention-based system, the number of reserved preamble resources might be small compared to non-reserved preamble resources used in contention-based RACH procedure. Therefore, non-contention based resources might not be sufficient to transmit new beam identifiers based on another reference signal, such as SS-block. 
     This disclosure proposes signaling procedures for the new beam identification in the beam recovery procedure. Using this new beam identification approach, can comprise using new channels for recovery request transmission from the UE to the network. 
     A two-step procedure can be used, wherein the first step comprises using configured CSI-RS resources to identify a new beam, and where the second step comprises using SS-block transmitted RS to identify the new beam. In NR initial access, synchronization signals (e.g., a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and/or a primary broadcast channel (PBCH)) can be transmitted within an SS-block. One or multiple SS-blocks compose an SS burst. One or multiple SS bursts compose an SS burst set where the number of SS bursts within an SS burst set is finite. A given number of SS blocks per cell can be transmitted with a given periodicity, depending on the carrier frequency, to establish synchronization of the UE with a network device of the network. SS-blocks are not configured per UE, but rather transmitted periodically by the network. 
     In one embodiment, during the two-step beam identification procedure, based on configured CSI-RS resources in step 1, a new beam can be identified, and identification data associated with the new beam can be reported in a recovery request transmission. In another scenario where the configured CSI-RS fails to identify a new beam, a second step, can comprise utilization of SS-blocks to identify the new beam. SS-block based new candidate beam identification can then be signaled to the network via the recovery request transmission. Additionally, for the case where the CSI-RS is not configured in the network, the SS-block based new candidate beam identification can then be signaled to the network via the recovery request transmission. 
     In another embodiment, use of a channel associated with the recovery request transmission, can prompt a modified contention-based RACH procedure to report on the new identified beam in the 2-step approach be used in the aforementioned embodiment. For example, when configured CSI-RS resources are used for new beam identification, non-contention channel based on physical (P)RACH can be used for beam recovery request transmissions. The required overhead to report on identified beams using configured CSI-RS is not significant enough to merit the use contention-based RACH preamble resources. For the two-step new beam identification procedure, when the SS-block is used to identify new beams, the number of the SS-blocks transmitted for a given cell identification (ID) can lead to a large overhead that cannot be handled by reserving contention-free preamble resources such as in the RACH-like contention-free method used for the configured CSI-RS. For such large overhead, contention-based RACH resources can be used. 
     Instead of using a traditional 4-step RACH procedure, akin to that used in initial access, a modified 2-step RACH procedure can be used such that the preamble resources for the contention based procedure are used to indicate the SS-block used for the new beam identification to the network, and a random access response is used by the network to signal the detection of the transmitted preamble and a timing synchronization alignment instruction to synchronize subsequent uplink transmissions from the UE. The proposed RACH procedure does not require transmission of a message to indicate the user ID, since the UE is known to the network, and does not subsequently require contention resolution. 
     In one embodiment, described herein is a method comprising in response to a determination of a first failure of a reference signal configured to manage a first beam, the first failure indicating that the reference signal was not received, determining a second failure associated with the first beam, wherein the reference signal and the first beam are to be received by the mobile device from a network device of the wireless network. In response to a condition associated with the reference signal being determined to have been satisfied, the method can comprise identifying a second beam that is not the first beam. The method can also facilitate a transmission of the second beam via a transmission channel for a recovery request related to a recovery associated with the first beam to mitigate the second failure. 
     According to another embodiment, a system can facilitate, in response to a first determination of a first failure associated with a reference signal configured to manage a first beam, determining a second failure associated with a first beam, wherein the reference signal and the first beam have been directed to the mobile device from a network device of a wireless network. In response to a condition associated with the reference signal being determined to have been satisfied, the system can identify a second beam that is not the first beam, wherein the condition is further associated with a second determination that the reference signal does not identify the second beam. In response to the second determination that the reference signal does not identify the second beam, the system can utilize a synchronization signal block associated with a synchronization signal to identify the second beam. Furthermore, the system can transmit the second beam via a random access channel for a recovery request related to a recovery of the first beam to rectify the second failure. 
     According to yet another embodiment, described herein is a machine-readable storage medium that can perform the operations comprising in response to a first determination of a first failure associated with a blocked reference signal of a wireless network, determining a second failure associated with a first beam associated with the blocked reference signal. In response to a condition associated with the blocked reference signal being determined to have been satisfied, the machine-readable storage medium can facilitate identifying a second beam, wherein the condition is further associated with a second determination that the blocked reference signal does not identify the second beam. In response to the second determination that the blocked reference signal does not identify the second beam, the machine-readable storage medium can facilitate utilizing a synchronization signal block associated with a synchronization signal to identify the second beam. Additionally, the machine-readable storage medium can facilitate transmitting data associated with the second beam via a random access channel for a recovery request related to a recovery of the first beam to rectify the second failure. 
     These and other embodiments or implementations are described in more detail below with reference to the drawings. 
     Referring now to  FIG. 1 , illustrated is an example wireless communication system  100  in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system  100  can comprise one or more user equipment UEs  102 . The non-limiting term user equipment can refer to any type of device that can communicate with a network node in a cellular or mobile communication system. A UE can have one or more antenna panels having vertical and horizontal elements. Examples of a UE comprise a target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communications, personal digital assistant (PDA), tablet, mobile terminals, smart phone, laptop mounted equipment (LME), universal serial bus (USB) dongles enabled for mobile communications, a computer having mobile capabilities, a mobile device such as cellular phone, a laptop having laptop embedded equipment (LEE, such as a mobile broadband adapter), a tablet computer having a mobile broadband adapter, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. User equipment UE  102  can also comprise IOT devices that communicate wirelessly. 
     In various embodiments, system  100  is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE  102  can be communicatively coupled to the wireless communication network via a network node  104 . The network node (e.g., network node device) can communicate with user equipment (UE), thus providing connectivity between the UE and the wider cellular network. The UE  102  can send transmission type recommendation data to the network node  104 . The transmission type recommendation data can comprise a recommendation to transmit data via a closed loop MIMO mode and/or a rank-1 precoder mode. 
     A network node can have a cabinet and other protected enclosures, an antenna mast, and multiple antennas for performing various transmission operations (e.g., MIMO operations). Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. In example embodiments, the UE  102  can send and/or receive communication data via a wireless link to the network node  104 . The dashed arrow lines from the network node  104  to the UE  102  represent downlink (DL) communications and the solid arrow lines from the UE  102  to the network nodes  104  represents an uplink (UL) communication. 
     System  100  can further include one or more communication service provider networks  106  that facilitate providing wireless communication services to various UEs, including UE  102 , via the network node  104  and/or various additional network devices (not shown) included in the one or more communication service provider networks  106 . The one or more communication service provider networks  106  can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system  100  can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks  106  can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.). The network node  104  can be connected to the one or more communication service provider networks  106  via one or more backhaul links  108 . For example, the one or more backhaul links  108  can comprise wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links  108  can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation). 
     Wireless communication system  100  can employ various cellular systems, technologies, and modulation modes to facilitate wireless radio communications between devices (e.g., the UE  102  and the network node  104 ). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g., LTE FDD/TDD, GSM/GERAN, CDMA2000 etc. 
     For example, system  100  can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system  100  are particularly described wherein the devices (e.g., the UEs  102  and the network device  104 ) of system  100  are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled). 
     In various embodiments, system  100  can be configured to provide and employ 5G wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, Internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs). Considering the drastic different communication needs of these different traffic scenarios, the ability to dynamically configure waveform parameters based on traffic scenarios while retaining the benefits of multi carrier modulation schemes (e.g., OFDM and related schemes) can provide a significant contribution to the high speed/capacity and low latency demands of 5G networks. With waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to an improved spectrum utilization for 5G networks. 
     To meet the demand for data centric applications, features of proposed 5G networks may comprise: increased peak bit rate (e.g., 20 Gbps), larger data volume per unit area (e.g., high system spectral efficiency—for example about 3.5 times that of spectral efficiency of long term evolution (LTE) systems), high capacity that allows more device connectivity both concurrently and instantaneously, lower battery/power consumption (which reduces energy and consumption costs), better connectivity regardless of the geographic region in which a user is located, a larger numbers of devices, lower infrastructural development costs, and higher reliability of the communications. Thus, 5G networks may allow for: data rates of several tens of megabits per second should be supported for tens of thousands of users, 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor, for example; several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments; improved coverage, enhanced signaling efficiency; reduced latency compared to LTE. 
     The upcoming 5G access network may utilize higher frequencies (e.g., &gt;6 GHz) to aid in increasing capacity. Currently, much of the millimeter wave (mmWave) spectrum, the band of spectrum between 30 gigahertz (GHz) and 300 GHz is underutilized. The millimeter waves have shorter wavelengths that range from 10 millimeters to 1 millimeter, and these mmWave signals experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming. 
     Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications, and has been widely recognized a potentially important component for access networks operating in higher frequencies. MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain. For these reasons, MIMO systems are an important part of the 3rd and 4th generation wireless systems, and are planned for use in 5G systems. 
     Referring now to  FIG. 2 , illustrated an example schematic system block diagram of a random access message sequence chart according to one or more embodiments. A standard message sequence chart  200  for a 4-step random access procedure in next generation cellular networks is depicted in  FIG. 2 . Random access allows the UE  102  to request a connection setup with the network node  104 . Random access can be used for initial access (e.g., moving from radio resource control (RRC)-idle to RRC-connected), to re-establish a connection, after link failure, for handover. 
     The 4-step random access procedure illustrated comprises a UE  102  transmitting a random access preamble for the network to estimate the UE timing and establish uplink (UL) synchronization in Message 1. Message 2, from the network node  104 , can comprise a random access response for transmitting a timing advance command to adjust the device transmit timing, and assign uplink resources for the device to use for Message. 3. Message 3, sent from the UE  102 , can comprise an UL physical UL shared channel (PUSCH) to transmit the UE identity, among other information, to the network node  104 . This is similar to normal scheduled data, and the content of Message 3 depends on the state of the device. Message 4 from the network node  104  can comprise contention resolution on a DL physical downlink shared channel (PDSCH) if there is a contention due to multiple users trying to access the network. 
     In addition to the baseline contention-based 4-step RACH procedure, a contention-free random access procedure can be defined, where the network can assign a dedicated preamble signature to the UE  102 , so that UEs  102  do not have to contend for preamble resources. This simplifies the procedure to a 2-step procedure that only has a preamble transmission step, and a random access response step. The contention-free RACH procedure can reduce the latency in cases such as handover. 
     Additionally, a third random access procedure can possibly be defined where the 4-step procedure is replaced by a simplified 2-step procedure. This simplified RACH procedure is motivated by a reduction in the overhead and delay, when a small packet is transmitted. It can also be beneficial in an unlicensed scenario, or an LTE-assisted random access procedure. 
     For the 2-step (simplified) RACH procedure, transmission contents are combined into two steps. Message 1 is transmitted in step 1, and Message 2 is transmitted in step 2. Message 1 in the 2-step procedure can be thought of as combining Message 1 and Message 3 in the 4-step procedure, whereas the preamble can be sent followed by the message part that contains the device identity in addition to other mobile device messages. The Message 2 in step 2 of the 2-step RACH procedure can be thought of as combining Message 2 and Message 4, whereas a Message 2 carries timing advance, UL grant and contention resolution information. 
     NR supports a 4-step random access procedure as a baseline. Random access procedure is supported for both RRC-idle (idle) and RRC-connected (connected) UEs. At least for UE in idle mode, the UE can select the subset of RACH preamble indices based on DL measurement and association indicated by system information (SI). 
     Referring now to  FIG. 3 , illustrated is an example schematic system block diagram of beam failure recovery chart  300  according to one or more embodiments. During a channel measurement campaign, one of the mmWave propagation problems is a blockage effect. As a result of smaller wave lengths, objects around a user, including the user, might temporarily block the mmWave propagation in a certain direction. The narrower beamforming of NR can increase the magnitude of this effect. Therefore, bam failure recovery can also comprise the following procedure as indicated in the beam failure recovery chart  300 . 
     The network node  104  can send a downlink signal transmission to the UE  102 . The UE  102  can then identify a beam failure  302  based on the configured RS resource using that beam. The UE  102  can also identify alternative beams pair links  304  (including Tx and Rx beams) as new beams to interact with. The UE  102  can then transmit uplink signaling (i.e., recovery request transmission) to the network node  104  to indicate the beam failure as well as the alternative beam pairs. Thereafter, the UE  102  can then switch to a physical channel downlink control information (PDCCH) receiver beam according by utilizing the alternative beam pairs  306  to monitor the PDCCH for confirmation from the network node  104  (e.g., gNB confirmation). 
     Referring now to  FIG. 4 , illustrated is an example schematic system block diagram of beam identification by configured CSI-RS according to one or more embodiments. The 2-step procedure  400  can begin with a downlink signal transmission being sent from the network node  104  to the UE  102 . Therefore, the first step can use configured CSI-RS resources to identify a new beam. For example, the UE  102  can determine beam failure based on a configured CSI-RS  402 . At step 2, the UE  102  can identify a new beam based on the configured CSI-RS resources in step 1. Thus, the new beam information can be reported in the recovery request transmission of an uplink signal. 
     Referring now to  FIG. 5  illustrates an example schematic system block diagram of beam identification by an SS-block according to one or more embodiments. In another embodiment, the 2-step procedure  500  can begin with a downlink signal transmission being sent from the network node  104  to the UE  102 . For this scenario, step 1 can comprise a configured CSI-RS failing to identify a new beam  502 . However, the second step, can comprise identification of new beams based on SS-blocks  504 . In NR initial access, synchronization signals NR-PSS, NR-SSS and/or NR-PBCH can be transmitted within an SS-block. One or multiple SS-blocks compose an SS burst. One or multiple SS bursts compose a SS burst set where the number of SS bursts within an SS burst set is finite. A given number of SS blocks per cell can be transmitted with a given periodicity, depending on the carrier frequency, to establish synchronization of the UE  102  with the network node  104 . SS-blocks are not configured per UE  102 , but rather transmitted periodically by the network node  104 . 
     The second step comprises using other transmitted RS (e.g., others besides the configured CSI-RS) for new candidate beam identification, wherein the RS used in the second step can be based on SS-block. The SS-block based new candidate beam identification can then be signaled to the network via a recovery request transmission of an uplink signal. 
     Referring now to  FIG. 6 , illustrated is an example schematic system block diagram of beam identification by configured CSI-RS and a non-contention channel according to one or more embodiments. This embodiment comprises a 2-step procedure  600  that can begin with a downlink signal transmission being sent from the network node  104  to the UE  102 . Therefore, the first step can leverage configured CSI-RS resources to determine a beam failure. For example, the UE  102  can determine beam failure based on a configured CSI-RS  602 . At step 2, the UE  102  can identify a new beam based on the configured CSI-RS resources in step 1. Thus, the new beam information can be reported in the recovery request transmission of an uplink signal. However, in this embodiment, a non-contention channel (e.g., assigning a preamble to the UE  102 ) associated with a PRACH can be used for beam recovery request transmission. Thus, the required overhead to report on the identified beam using configured CSI-RS is not significant enough to use contention-based RACH preamble resources. 
     Referring now to  FIG. 7 , illustrated is an example schematic system block diagram of beam identification by an SS-block and a contention channel according to one or more embodiments. In yet another embodiment comprising a 2-step procedure  700 , a downlink signal transmission can be sent from the network node  104  to the UE  102 . For the scenario, when a configured CSI-RS fails to identify a new beam  702 , the new beam can be identified by the SS-blocks  704 . In NR initial access, synchronization signals NR-PSS, NR-SSS and/or NR-PBCH can be transmitted within an SS-block. One or multiple SS-blocks compose an SS burst. One or multiple SS bursts compose a SS burst set where the number of SS bursts within an SS burst set is finite. A given number of SS blocks per cell can be transmitted with a given periodicity, depending on the carrier frequency, to establish synchronization of the UE  102  with the network node  104 . SS-blocks are not configured per UE  102 , but rather transmitted periodically by the network node  104 . 
     The second step comprises using other transmitted RS (e.g., others besides the configured CSI-RS) for new candidate beam identification, wherein the RS used in the second step can be based on SS-block. The SS-block based new candidate beam identification can then be signaled to the network via a recovery request transmission of an uplink signal. 
     For the two-step new beam identification procedure, when SS-block is used to identify new beams, the number of SS-blocks transmitted for a given cell ID might lead to a large overhead that cannot be handled by reserving contention-free preamble resources such as similar to the RACH contention-free method used for configured CSI-RS. Thus, for such large overhead, contention-based RACH resources can be used. 
     Referring now to  FIG. 8 , illustrated is an example schematic system block diagram of beam identification by an SS-block and contention channel based on a non-configured CSI-RS according to one or more embodiments. This embodiment comprises a 2-step procedure  800  that can begin with a downlink signal transmission being sent from the network node  104  to the UE  102 . In this scenario, when the CSI-RS is not configured in the network  802 , the SS-block can identify the new beam  804  and transmit in the recovery request transmission via an uplink signal transmission. 
     In NR initial access, synchronization signals NR-PSS, NR-SSS and/or NR-PBCH can be transmitted within an SS-block. One or multiple SS-blocks compose an SS burst. One or multiple SS bursts compose a SS burst set where the number of SS bursts within an SS burst set is finite. A given number of SS blocks per cell can be transmitted with a given periodicity, depending on the carrier frequency, to establish synchronization of the UE  102  with the network node  104 . SS-blocks are not configured per UE  102 , but rather transmitted periodically by the network node  104 . 
     The second step comprises using other transmitted RS (e.g., others besides the configured CSI-RS) for new candidate beam identification, wherein the RS used in the second step can be based on SS-block. The SS-block based new candidate beam identification can then be signaled to the network via a recovery request transmission of an uplink signal. 
     For the two-step new beam identification procedure, when SS-block is used to identify new beams, the number of SS-blocks transmitted for a given cell ID can lead to a large overhead that may not be handled by reserving contention-free preamble resources such as those similar to the RACH contention-free method used for the configured CSI-RS. Thus, for such large overhead, contention-based RACH resources can be used. 
     Referring now to  FIG. 9 , illustrates an example schematic system block diagram of modified contention based RACH procedure according to one or more embodiments. Instead of using a traditional 4-step RACH procedure, akin to that used in initial access, a modified 2-step RACH procedure  900  is represented. The modified RACH procedure can comprise preamble resources (e.g., Message 1: random access preamble) for the contention-based procedure, which can be used to indicate the SS-block used for new beam identification to the network node  104 , and a random access response (e.g., Message 2) can be used by the network node  104  to signal the detection of the transmitted preamble and a timing alignment instruction to synchronize subsequent uplink transmissions from the UE  102 . The proposed RACH procedure does not, however, require transmission of a Message 3 to indicate the UE ID, since the UE  102  is known to the network node  104 , and does not subsequently require contention resolution. The proposed modified contention based RACH procedure for recovery request transmission can further be applied to the simplified 2-RACH procedure, whereas the signaling in the simplified 2-step RACH procedure can be further reduced in the Message 1 and Message 2 to only account for the signaling required to deliver and identify the preamble resources by the UE  102  and the network node  104 . 
     Referring now to  FIG. 10 , illustrated is an example flow chart for beam selection according to one or more embodiments. The beam selection flow chart  1000  can begin at step  1002 . It should be understood that to begin this process, a downlink signal transmission can be sent from the network node  104  to the UE  102 . Block  1004  comprises a CSI-RS. If the CSI-RS is configured, then the decision tree can select yes at step  1006  and proceed to block  1010  for the new beam. Alternatively, if the CSI-RS is not configured, then the decision tree can select no at step  1006  and proceed to identify the new beam via SS blocks of block  1008  at the UE  102 . Thereafter, the UE  102  can send a recovery request transmission for the new beam, at block  1014 , to the network node  104 . Sending the recovery request transmission based on the SS-block identification can also end the process at the end block  1014 . 
     If the new beam is identified at step  1012 , then the UE  102  can send a recovery request transmission for the new beam, at block  1014 , to the network node  104 . Sending the recovery request transmission can end the process at the end block  1014 . Alternatively, if the new beam is not identified at step  1012 , then SS-blocks can be used to identify the new beam by the UE  102  at block  1008 . Thereafter, the UE  102  can send a recovery request transmission for the new beam, at block  1014 , to the network node  104 . Sending the recovery request transmission based on the SS-block identification can also end the process at the end block  1014 . 
     Referring now to  FIG. 11 , illustrated is an example flow diagram for a method for beam selection  1100  for a 5G network according to one or more embodiments. In response to a determination of a first failure of a reference signal configured to manage a first beam, the first failure indicating that the reference signal was not received, a method can determine a second failure (e.g., via a UE  102 ) associated with the first beam, wherein the reference signal and the first beam are to be received by the mobile device from a network device of the wireless network at element  1102 . In response to a condition associated with the reference signal being determined to have been satisfied, the method can comprise identifying (e.g., via a UE  102 ) a second beam that is not the first beam at element  1104 . The method can also facilitate a transmission of the second beam via a transmission channel for a recovery request related to a recovery associated with the first beam to mitigate the second failure at element  1106 . 
     Referring now to  FIG. 12 , illustrated is an example flow diagram for a system for beam selection  1200  for a 5G network according to one or more embodiments. In response to a determination of a first failure associated with a reference signal configured to manage a first beam, the system can determine a second failure (e.g., via a UE  102 ) associated with the first beam, wherein the reference signal and the first beam have been directed to the mobile device from a network device of a wireless network at element  1202 . In response to a condition associated with the reference signal being determined to have been satisfied, the system can identify (e.g., via a UE  102 ) a second beam that is not the first beam, wherein the condition is further associated with a second determination that the reference signal does not identify the second beam at element  1204 . Additionally, in response to the second determination that the reference signal does not identify the second beam, the system can utilize a synchronization signal block (e.g., via a UE  102 ) associated with a synchronization signal to identify the second beam at element  1206 . Furthermore, the system can transmit (e.g., via a UE  102 ) the second beam via a random access channel for a recovery request related to a recovery of the first beam to rectify the second failure at element  1208 . 
     Referring now to  FIG. 13 , illustrated is an example flow diagram for machine-readable medium for beam selection  1300  for a 5G network according to one or more embodiments. In response to a first determination of a first failure associated with a blocked reference signal of a wireless network, the machine-readable storage medium can facilitate determining a second failure associated (e.g., via a UE  102 ) with a first beam associated with the blocked reference signal at element  1302 . At element  1304 , in response to a condition associated with the blocked reference signal being determined to have been satisfied, the machine-readable storage medium can facilitate identifying (e.g., via a UE  102 ) a second beam, wherein the condition is further associated with a second determination that the blocked reference signal does not identify the second beam. In response to the second determination that the blocked reference signal does not identify the second beam, the machine-readable storage medium can facilitate utilizing (e.g., via a UE  102 ) a synchronization signal block associated with a synchronization signal to identify the second beam at element  1306 . Additionally, at element  1308 , the machine-readable storage medium can facilitate transmitting data (e.g., via a UE  102 ) associated with the second beam via a random access channel for a recovery request related to a recovery of the first beam to rectify the second failure. 
     Referring now to  FIG. 14 , illustrated is a schematic block diagram of a user equipment (e.g., user equipment  102 ) that can be a mobile device  1400  capable of connecting to a network in accordance with some embodiments described herein. Although a mobile handset  1400  is illustrated herein, it will be understood that other devices can be a mobile device, and that the mobile handset  1400  is merely illustrated to provide context for the embodiments of the various embodiments described herein. The following discussion is intended to provide a brief, general description of an example of a suitable environment  1400  in which the various embodiments can be implemented. While the description includes a general context of computer-executable instructions embodied on a machine-readable storage medium, those skilled in the art will recognize that the innovation also can be implemented in combination with other program modules and/or as a combination of hardware and software. 
     Generally, applications (e.g., program modules) can include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the methods described herein can be practiced with other system configurations, including single-processor or multiprocessor systems, minicomputers, mainframe computers, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices. 
     A computing device can typically include a variety of machine-readable media. Machine-readable media can be any available media that can be accessed by the computer and includes both volatile and non-volatile media, removable and non-removable media. By way of example and not limitation, computer-readable media can comprise computer storage media and communication media. Computer storage media can include volatile and/or non-volatile media, removable and/or non-removable media implemented in any method or technology for storage of information, such as computer-readable instructions, data structures, program modules or other data.

     Communication media typically embodies computer-readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism, and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer-readable media. 
     The handset  1400  includes a processor  1402  for controlling and processing all onboard operations and functions. A memory  1404  interfaces to the processor  1402  for storage of data and one or more applications  1406  (e.g., a video player software, user feedback component software, etc.).

     The handset  1400  includes a display  1412  for displaying text, images, video, telephony functions (e.g., a Caller ID function), setup functions, and for user input. For example, the display  1412  can also be referred to as a “screen” that can accommodate the presentation of multimedia content (e.g., music metadata, messages, wallpaper, graphics, etc.). The display  1412  can also display videos and can facilitate the generation, editing and sharing of video quotes. A serial I/O interface  1414  is provided in communication with the processor  1402  to facilitate wired and/or wireless serial communications (e.g., USB, and/or IEEE 1394) through a hardwire connection, and other serial input devices (e.g., a keyboard, keypad, and mouse). This supports updating and troubleshooting the handset  1400 , for example. Audio capabilities are provided with an audio I/O component  1416 , which can include a speaker for the output of audio signals related to, for example, indication that the user pressed the proper key or key combination to initiate the user feedback signal. The audio I/O component  1416  also facilitates the input of audio signals through a microphone to record data and/or telephony voice data, and for inputting voice signals for telephone conversations. 
     The handset  1400  can include a slot interface  1418  for accommodating a SIC (Subscriber Identity Component) in the form factor of a card Subscriber Identity Module (SIM) or universal SIM  1420 , and interfacing the SIM card  1420  with the processor  1402 . However, it is to be appreciated that the SIM card  1420  can be manufactured into the handset  1400 , and updated by downloading data and software. 
     The handset  1400  can process IP data traffic through the communication component  1410  to accommodate IP traffic from an IP network such as, for example, the Internet, a corporate intranet, a home network, a person area network, etc., through an ISP or broadband cable provider. Thus, VoIP traffic can be utilized by the handset  1400  and IP-based multimedia content can be received in either an encoded or decoded format. 
     A video processing component  1422  (e.g., a camera) can be provided for decoding encoded multimedia content. The video processing component  1422  can aid in facilitating the generation, editing and sharing of video quotes. The handset  1400  also includes a power source  1424  in the form of batteries and/or an AC power subsystem, which power source  1424  can interface to an external power system or charging equipment (not shown) by a power I/O component  1426 . 
     The handset  1400  can also include a video component  1430  for processing video content received and, for recording and transmitting video content. For example, the video component  1430  can facilitate the generation, editing and sharing of video quotes.

As described hereinabove, this can occur when the user initiates the feedback signal automatically or manually. A user input component  1434  facilitates the user initiating the quality feedback signal. The user input component  1434  can also facilitate the generation, editing and sharing of video quotes. The user input component  1434  can include such conventional input device technologies such as a keypad, keyboard, mouse, stylus pen, and/or touch screen, for example. 
     Referring again to the applications  1406 , a hysteresis component  1436  facilitates the analysis and processing of hysteresis data, which is utilized to determine when to associate with the access point. A software trigger component  1438  can be provided that facilitates triggering of the hysteresis component  1436  when the Wi-Fi transceiver  1413  detects the beacon of the access point. A SIP client  1440  enables the handset  1400  to support SIP protocols and register the subscriber with the SIP registrar server. The applications  1406  can also include a client  1442  that provides at least the capability of discovery, play and store of multimedia content, for example, music. 
     The handset  1400 , as indicated above related to the communications component  1410 , includes an indoor network radio transceiver  1413  (e.g., Wi-Fi transceiver). This function supports the indoor radio link, such as IEEE 802.11, for the dual-mode GSM handset  1400 . The handset  1400  can accommodate at least satellite radio services through a handset that can combine wireless voice and digital radio chipsets into a single handheld device. 
     Referring now to  FIG. 15 , there is illustrated a block diagram of a computer  1500  operable to execute the functions and operations performed in the described example embodiments. For example, a network node (e.g., network node  104 ) may contain components as described in  FIG. 15 . The computer  1500  can provide networking and communication capabilities between a wired or wireless communication network and a server and/or communication device. In order to provide additional context for various aspects thereof,  FIG. 15  and the following discussion are intended to provide a brief, general description of a suitable computing environment in which the various aspects of the innovation can be implemented to facilitate the establishment of a transaction between an entity and a third party. While the description above is in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the innovation also can be implemented in combination with other program modules and/or as a combination of hardware and software. 
     Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the various methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices. 
     The illustrated aspects of the innovation can also be practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices. 
     Computing devices typically include a variety of media, which can include computer-readable storage media or communications media, which two terms are used herein differently from one another as follows. 
     Computer-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible and/or non-transitory media which can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium. 
     Communications media can embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. 
     With reference to  FIG. 15 , implementing various aspects described herein with regards to devices can include a computer  1500 , the computer  1500  including a processing unit  1504 , a system memory  1506  and a system bus  1508 . The system bus  1508  couples system components including, but not limited to, the system memory  1506  to the processing unit  1504 . The processing unit  1504  can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit  1504 . 
     The system bus  1508  can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory  1506  includes read-only memory (ROM)  1527  and random access memory (RAM)  1512 . A basic input/output system (BIOS) is stored in a non-volatile memory  1527  such as ROM, EPROM, EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer  1500 , such as during start-up. The RAM  1512  can also include a high-speed RAM such as static RAM for caching data. 
     The computer  1500  further includes an internal hard disk drive (HDD)  1514  (e.g., EIDE, SATA), which internal hard disk drive  1514  can also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive (FDD)  1516 , (e.g., to read from or write to a removable diskette  1518 ) and an optical disk drive  1520 , (e.g., reading a CD-ROM disk  1522  or, to read from or write to other high capacity optical media such as the DVD). The hard disk drive  1514 , magnetic disk drive  1516  and optical disk drive  1520  can be connected to the system bus  1508  by a hard disk drive interface  1524 , a magnetic disk drive interface  1526  and an optical drive interface  1528 , respectively. The interface  1524  for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE 1294 interface technologies. Other external drive connection technologies are within contemplation of the subject innovation. 
     The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer  1500  the drives and media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer  1500 , such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the example operating environment, and further, that any such media can contain computer-executable instructions for performing the methods of the disclosed innovation. 
     A number of program modules can be stored in the drives and RAM  1512 , including an operating system  1530 , one or more application programs  1532 , other program modules  1534  and program data  1536 . All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM  1512 . It is to be appreciated that the innovation can be implemented with various commercially available operating systems or combinations of operating systems. 
     A user can enter commands and information into the computer  1500  through one or more wired/wireless input devices, e.g., a keyboard  1538  and a pointing device, such as a mouse  1540 . Other input devices (not shown) may include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit  1504  through an input device interface  1542  that is coupled to the system bus  1508 , but can be connected by other interfaces, such as a parallel port, an IEEE 2394 serial port, a game port, a USB port, an IR interface, etc. 
     A monitor  1544  or other type of display device is also connected to the system bus  1508  through an interface, such as a video adapter  1546 . In addition to the monitor  1544 , a computer  1500  typically includes other peripheral output devices (not shown), such as speakers, printers, etc. 
     The computer  1500  can operate in a networked environment using logical connections by wired and/or wireless communications to one or more remote computers, such as a remote computer(s)  1548 . The remote computer(s)  1548  can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment device, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer, although, for purposes of brevity, only a memory/storage device  1550  is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN)  1552  and/or larger networks, e.g., a wide area network (WAN)  1554 . Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet. 
     When used in a LAN networking environment, the computer  1500  is connected to the local network  1552  through a wired and/or wireless communication network interface or adapter  1556 . The adapter  1556  may facilitate wired or wireless communication to the LAN  1552 , which may also include a wireless access point disposed thereon for communicating with the wireless adapter  1556 . 
     When used in a WAN networking environment, the computer  1500  can include a modem  1558 , or is connected to a communications server on the WAN  1554 , or has other means for establishing communications over the WAN  1554 , such as by way of the Internet. The modem  1558 , which can be internal or external and a wired or wireless device, is connected to the system bus  1508  through the input device interface  1542 . In a networked environment, program modules depicted relative to the computer, or portions thereof, can be stored in the remote memory/storage device  1550 . It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used. 
     The computer is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least Wi-Fi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices. 
     Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE802.11 (a, b, g, n, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11b) or 54 Mbps (802.11a) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic “10BaseT” wired Ethernet networks used in many offices.

In this regard, it will also be recognized that the embodiments comprise a system as well as a computer-readable medium having computer-executable instructions for performing the acts and/or events of the various methods. 
     Computing devices typically comprise a variety of media, which can comprise computer-readable storage media and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media can be any available storage media that can be accessed by the computer and comprises both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can comprise, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible and/or non-transitory media which can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium. 
     On the other hand, communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and comprises any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communications media comprise wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. 
     Further, terms like “user equipment,” “user device,” “mobile device,” “mobile,” station,” “access terminal,” “terminal,” “handset,” and similar terminology, generally refer to a wireless device utilized by a subscriber or user of a wireless communication network or service to receive or convey data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream. The foregoing terms are utilized interchangeably in the subject specification and related drawings. Likewise, the terms “access point,” “node B,” “base station,” “evolved Node B,” “cell,” “cell site,” and the like, can be utilized interchangeably in the subject application, and refer to a wireless network component or appliance that serves and receives data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream from a set of subscriber stations. Data and signaling streams can be packetized or frame-based flows. It is noted that in the subject specification and drawings, context or explicit distinction provides differentiation with respect to access points or base stations that serve and receive data from a mobile device in an outdoor environment, and access points or base stations that operate in a confined, primarily indoor environment overlaid in an outdoor coverage area. Data and signaling streams can be packetized or frame-based flows. 
     Furthermore, the terms “user,” “subscriber,” “customer,” “consumer,” and the like are employed interchangeably throughout the subject specification, unless context warrants particular distinction(s) among the terms. It should be appreciated that such terms can refer to human entities, associated devices, or automated components supported through artificial intelligence (e.g., a capacity to make inference based on complex mathematical formalisms) which can provide simulated vision, sound recognition and so forth. In addition, the terms “wireless network” and “network” are used interchangeable in the subject application, when context wherein the term is utilized warrants distinction for clarity purposes such distinction is made explicit. 
     Moreover, the word “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. 
     Existing solutions for beam recovery request transmission is to use non-contention based RACH-like resources to inform the network of the identified new beam and the occurrence of beam failure. These resources might not be sufficient when another RS, other than configured CSI-RS is used for new beam identification, such as SS-block. Instead of using the traditional 4-step RACH procedure for beam recovery request transmission, a modified 2-step contention-based RACH procedure can save on overhead and latency associated with the traditional 4-step procedure.
