Patent Description:
The present disclosure relates generally to communication systems, and more particularly, to a random access procedure employed by a user equipment (UE).

<NUM> NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (loT)), and other requirements.

Each of the documents <CIT>, <CIT>, <CIT> and <CIT> discloses a method according to the precharacterizing part of independent claim <NUM>.

By way of example, and not limitation, such computer- readable media can comprise a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.

The wireless communications system (also referred to as a wireless wide area network (WWAN)) includes base stations <NUM>, UEs <NUM>, and a core network <NUM>.

The base stations <NUM> (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E- UTRAN)) interface with the core network <NUM> through backhaul links <NUM> (e.g., S1 interface). The base stations <NUM> may communicate directly or indirectly (e.g., through the core network <NUM>) with each other over backhaul links <NUM> (e.g., X2 interface).

There may be overlapping geographic coverage areas <NUM><NUM>. For example, the small cell <NUM>' may have a coverage area <NUM>' that overlaps the coverage area <NUM><NUM> of one or more macro base stations <NUM>. A network that includes both small cell and macro cells may be known as a heterogeneous network. The base stations <NUM> / UEs <NUM> may use spectrum up to Y MHz (e.g., <NUM>, <NUM>, <NUM>, <NUM>, <NUM>) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or less carriers may be allocated for DL than for UL).

The core network <NUM> may include a Mobility Management Entity (MME) <NUM>, other MMEs <NUM>, a Serving Gateway <NUM>, a Multimedia Broadcast Multicast Service (MBMS) Gateway <NUM>, a Broadcast Multicast Service Center (BM-SC) <NUM>, and a Packet Data Network (PDN) Gateway <NUM>. The MME <NUM> is the control node that processes the signaling between the UEs <NUM> and the core network <NUM>. The IP Services <NUM> may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service (PSS), and/or other IP services.

The base station may also be referred to as a gNB, Node B, evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), or some other suitable terminology. The base station <NUM> provides an access point to the core network <NUM> for a UE <NUM>. Examples of UEs <NUM> include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a toaster, or any other similar functioning device. Some of the UEs <NUM> may be referred to as loT devices (e.g., parking meter, gas pump, toaster, vehicles, etc.).

In the DL, IP packets from the core network <NUM> may be provided to a controller/processor <NUM>.

Each spatial stream may then be provided to a different antenna <NUM> via a separate transmitter 218TX. Each transmitter 218TX may modulate an RF carrier with a respective spatial stream for transmission.

At the UE <NUM>, each receiver 254RX receives a signal through its respective antenna <NUM>. Each receiver 254RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor <NUM>.

The memory <NUM> may be referred to as a computer- readable medium. In the UL, the controller/processor <NUM> provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the core network <NUM>.

The spatial streams generated by the TX processor <NUM> may be provided to different antenna <NUM> via separate transmitters 254TX. Each transmitter 254TX may modulate an RF carrier with a respective spatial stream for transmission. Each receiver 218RX receives a signal through its respective antenna <NUM>. Each receiver 218RX recovers information modulated onto an RF carrier and provides the information to a RX processor <NUM>.

The memory <NUM> may be referred to as a computer- readable medium. IP packets from the controller/processor <NUM> may be provided to the core network <NUM>.

NR may utilize OFDM with a cyclic prefix (CP) on the uplink and downlink and may include support for half-duplex operation using time division duplexing (TDD). NR may include Enhanced Mobile Broadband (eMBB) service targeting wide bandwidth (e.g. <NUM> beyond), millimeter wave (mmW) targeting high carrier frequency (e.g. <NUM>), massive MTC (mMTC) targeting non-backward compatible MTC techniques, and/or mission critical targeting ultra-reliable low latency communications (URLLC) service.

A single component carrier bandwidth of <NUM> may be supported. In one example, NR resource blocks (RBs) may span <NUM> sub-carriers with a sub-carrier bandwidth of <NUM> over a <NUM> duration or a bandwidth of <NUM> over a <NUM> duration. Each radio frame may consist of <NUM> or <NUM> subframes (or NR slots) with a length of <NUM>. Each subframe may indicate a link direction (i.e., DL or UL) for data transmission and the link direction for each subframe may be dynamically switched. Each subframe may include DL/UL data as well as DL/UL control data. UL and DL subframes for NR may be as described in more detail below with respect to <FIG> and <FIG>.

The NR RAN may include a central unit (CU) and distributed units (DUs). A NR BS (e.g., gNB, <NUM> Node B, Node B, transmission reception point (TRP), access point (AP)) may correspond to one or multiple BSs. NR cells can be configured as access cells (ACells) or data only cells (DCells). For example, the RAN (e.g., a central unit or distributed unit) can configure the cells. DCells may be cells used for carrier aggregation or dual connectivity and may not be used for initial access, cell selection/reselection, or handover. In some cases DCells may not transmit synchronization signals (SS) in some cases DCells may transmit SS. NR BSs may transmit downlink signals to UEs indicating the cell type. Based on the cell type indication, the UE may communicate with the NR BS. For example, the UE may determine NR BSs to consider for cell selection, access, handover, and/or measurement based on the indicated cell type.

<FIG> illustrates an example logical architecture <NUM> of a distributed RAN, according to aspects of the present disclosure. The backhaul interface to the next generation core network (NG- CN) <NUM> may terminate at the ANC.

The local architecture of the distributed RAN <NUM> may be used to illustrate fronthaul definition.

According to aspects, a dynamic configuration of split logical functions may be present within the architecture of the distributed RAN <NUM>. The PDCP, RLC, MAC protocol may be adaptably placed at the ANC or TRP.

The C- RU may have distributed deployment.

The DL-centric subframe may also include a common UL portion <NUM>. The common UL portion <NUM> may sometimes be referred to as an UL burst, a common UL burst, and/or various other suitable terms. The common UL portion <NUM> may include feedback information corresponding to various other portions of the DL-centric subframe. For example, the common UL portion <NUM> may include feedback information corresponding to the control portion <NUM>. Non-limiting examples of feedback information may include an ACK signal, a NACK signal, a HARQ indicator, and/or various other suitable types of information. The common UL portion <NUM> may include additional or alternative information, such as information pertaining to random access channel (RACH) procedures, scheduling requests (SRs), and various other suitable types of information.

As illustrated in <FIG>, the end of the DL data portion <NUM> may be separated in time from the beginning of the common UL portion <NUM>. One of ordinary skill in the art will understand that the foregoing is merely one example of a DL-centric subframe and alternative structures having similar features may exist without necessarily deviating from the aspects described herein.

<FIG> is a diagram <NUM> showing an example of an UL-centric subframe. The UL-centric subframe may include a control portion <NUM>. The control portion <NUM> may exist in the initial or beginning portion of the UL-centric subframe. The control portion <NUM> in <FIG> may be similar to the control portion <NUM> described above with reference to <FIG>. The UL-centric subframe may also include an UL data portion <NUM>. The UL data portion <NUM> may sometimes be referred to as the pay load of the UL-centric subframe. The UL portion may refer to the communication resources utilized to communicate UL data from the subordinate entity (e.g., UE) to the scheduling entity (e.g., UE or BS). In some configurations, the control portion <NUM> may be a physical DL control channel (PDCCH).

As illustrated in <FIG>, the end of the control portion <NUM> may be separated in time from the beginning of the UL data portion <NUM>. The UL-centric subframe may also include a common UL portion <NUM>. The common UL portion <NUM> in <FIG> may be similar to the common UL portion <NUM> described above with reference to <FIG>. The common UL portion <NUM> may additionally or alternatively include information pertaining to channel quality indicator (CQI), sounding reference signals (SRSs), and various other suitable types of information. One of ordinary skill in the art will understand that the foregoing is merely one example of an UL-centric subframe and alternative structures having similar features may exist without necessarily deviating from the aspects described herein.

<FIG> is a diagram <NUM> illustrating communications between a base station <NUM> and a UE <NUM>. The base station <NUM> may operates antenna ports <NUM>-<NUM> to <NUM>-N. The base station <NUM> provides transmitter side beams <NUM>-<NUM> to <NUM>-N at different directions. The UE <NUM> may use a random access procedure to gain access to a cell of the base station <NUM>. In this example, to facilitate a UE to perform the random access procedure, the base station <NUM> transmits a set of synchronization signal blocks (SSBs) including SSBs <NUM>-<NUM> to <NUM>-N, which are associated with the transmitter side beams <NUM>-<NUM> to <NUM>-N, respectively. More specifically, the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS), together with the Physical Broadcast Channel (PBCH), are jointly referred to as an SSB. Each of the SSBs <NUM>-<NUM> to <NUM>-N may include one or more Demodulation Reference Signals (DMRSs) for PBCH. The DMRSs are intended for channel estimation at a UE as part of coherent demodulation.

Further, the base station <NUM> may transmit CSI-RS sets <NUM>-<NUM> to <NUM>-N that are specific to the UE <NUM> by using the transmitter side beams <NUM>-<NUM> to <NUM>-N, respectively. A CSI-RS is used by the UE to estimate the channel and report channel state information (CSI) to the base station. A CSI-RS is configured on a per-device basis.

In certain configurations, the UE <NUM> may select one of the transmitter side beams <NUM>-<NUM> to <NUM>-N randomly or based on a rule for deriving a corresponding preamble sequence used in the random access procedure. In certain configurations, the UE <NUM> may adjust the direction of a receiver side beam <NUM> to detect and measure the SSBs <NUM>-<NUM> to <NUM>-N or the CSI-RS sets <NUM>-<NUM> to <NUM>-N. Based on the detection and/or measurements (e.g., SNR measurements), the UE <NUM> may select a direction of the receiver side beam <NUM> and one of the transmitter side beams <NUM>-<NUM> to <NUM>-N for deriving a corresponding preamble sequence used in the random access procedure.

In one example, the UE <NUM> may select the transmitter side beam <NUM>-<NUM> for deriving an associated preamble sequence for use in the random access procedure. More specifically, the UE <NUM> is configured with one or more random access resources associated with each the SSBs <NUM>-<NUM> to <NUM>-N and/or one or more random access resources associated with each the CSI-RS sets <NUM>-<NUM> to <NUM>-N.

Accordingly, the UE <NUM> may select a random access resource associated with the down-link reference signal (e.g., SSB or CSI-RS) of the transmitter side beam <NUM>-<NUM> (i.e., the selected one of the transmitter side beams <NUM>-<NUM> to <NUM>-N). Subsequently, the UE <NUM> sends a preamble sequence <NUM> to the base station <NUM> through the receiver side beam <NUM> (by assuming a corresponding UE transmit beam can be derived from the receiver side beam <NUM>) on the selected random access resource. Based on the location of the random access resource in time domain and frequency domain, the base station <NUM> can determine the transmitter side beam selected by the UE <NUM>.

Subsequently, the base station <NUM> and the UE <NUM> can further complete the random access procedure such that the base station <NUM> and the UE <NUM> can communicate through the transmitter side beam <NUM>-<NUM> and the receiver side beam <NUM>. As such, the UE <NUM> is in a connected state (e.g., RRC CONNECTED) with the base station <NUM>. The base station <NUM> may use the transmitter side beam <NUM>-<NUM> to transmit to the UE <NUM> a PDCCH <NUM>, a PDSCH <NUM>, and associated DMRSs <NUM>.

<FIG> is diagram <NUM> illustrating a random access procedure of a UE in a connected state. In certain circumstances, the UE <NUM>, although in a connected state, may need to conduct the random access procedure with the base station <NUM> or another base station. In this example, as described supra referring to <FIG>, the UE <NUM> is connected to the base station <NUM>. The UE <NUM> may receive a request (e.g., a PDCCH order) from the base station <NUM> to initiate a random access procedure again. The UE <NUM> may detect an uplink data arrival without uplink synchronization and, thus, may conduct the random access procedure with the base station <NUM>. The UE <NUM> may detect a down-link data arrival without uplink synchronization and, thus, may conduct the random access procedure with the base station <NUM> and, thus, may conduct the random access procedure with the base station <NUM>. The UE <NUM> may decide to recover a beam and, thus, may conduct the random access procedure with the base station <NUM>. The UE <NUM> may be handed over from the base station <NUM> to another base station and, thus, may conduct the random access procedure with the other base station.

In this example, at procedure <NUM>, the base station <NUM> sends a PDCCH order to the UE <NUM>. In particular, the PDCCH order may be transmitted by using the transmitter side beam <NUM>-<NUM>. Accordingly, upon received the PDCCH order, at procedure <NUM>, the UE <NUM> initiates a random access procedure while in a connected state. In another example, the UE <NUM> may detect a beam failure and internally generates a beam failure recovery request. Accordingly, the UE <NUM> can also initiate a random access procedure while in a connected state. At procedure <NUM>, as described supra, the base station <NUM> sends the SSBs <NUM>-<NUM> to <NUM>-N and/or the CSI-RS sets <NUM>-<NUM> to <NUM>-N associated with the transmitter side beams <NUM>-<NUM> to <NUM>-N, respectively. The UE <NUM> may detect some or all of the SSBs <NUM>-<NUM> to <NUM>-N. Note that procedure <NUM> can also take place before procedure <NUM>.

At procedure <NUM>, as described supra, in certain configurations, the UE <NUM> may select one of the transmitter side beams <NUM>-<NUM> to <NUM>-N randomly or based on the measurement result. As an example, the base station <NUM> may select the transmitter side beam <NUM>-<NUM> for deriving an associated preamble sequence <NUM> for use in the random access procedure.

Accordingly, the base station <NUM> may use a correspondent beam of the transmitter side beam <NUM>-<NUM> to receive the preamble sequence <NUM>, which is transmitted on a random access resource associated with the down-link reference signals of the transmitter side beam <NUM>-<NUM>. The UE <NUM> determines a timing advance (TA) for the UE <NUM> based on the preamble sequence <NUM> received through the transmitter side beam <NUM>-<NUM>.

As such, the base station <NUM> may receive the preamble sequence <NUM> on the transmitter side beam <NUM>-<NUM>. The network of the base station <NUM> can also determine that the preamble sequence <NUM> was transmitted at a random access resource associated with the SSB <NUM>-<NUM> and/or the CSI-RS set <NUM>-<NUM> of the transmitter side beam <NUM>-<NUM>. As such, the network learns that the UE <NUM> selected the transmitter side beam <NUM>-<NUM>.

At procedure <NUM>, the base station <NUM> (under the control of the network) generates a random-access response (RAR). The RAR may include information about the preamble sequence <NUM> the network detected and for which the response is valid, a TA calculated by the network based on the preamble sequence receive timing, a scheduling grant indicating resources the UE <NUM> will use for the transmission of the subsequent message, and/or a temporary identity, the TC-RNTI, used for further communication between the device and the network.

At procedure <NUM>, the base station <NUM> transmits a PDCCH scheduling command for scheduling transmission of the RAR by using the transmitter side beam <NUM>-<NUM>. Accordingly, DMRS of the PDCCH scheduling command and DMRS of the PDCCH order at procedure <NUM> are quasi-colocated. Further, the PDCCH scheduling command may be scrambled by a cell radio network temporary identifier (C-RNTI) of the UE <NUM>, which is known to the network. Further, as described supra, the UE <NUM> is in a connected state. The serving beam from the base station <NUM> to the UE <NUM> may be the transmitter side beam <NUM>-<NUM>. At or about the same time the base station <NUM> sends the PDCCH scheduling command for scheduling transmission of the RAR on the transmitter side beam <NUM>-<NUM>, the base station <NUM> may also send a PDCCH on the transmitter side beam <NUM>-<NUM> for scheduling a PDSCH carrying user data.

At procedure <NUM>, the base station <NUM> transmits the RAR to the UE <NUM> on the transmitter side beam <NUM>-<NUM>. The RAR may be transmitted in a conventional downlink PDSCH. As such, the random access procedure completes for the UE <NUM>, which is in a connected state.

<FIG> is a diagram <NUM> illustrating that a UE transmits a preamble sequence, a PUCCH, a PUSCH, and/or a sounding reference signal (SRS) in a time slot. More specifically, the UE <NUM> may decide to transmit the preamble sequence <NUM> (as described supra referring to <FIG>) to the base station <NUM> in a slot <NUM>. Further, in this example, as the UE <NUM> is in a connected state, the UE <NUM> may also be configured to transmit a PUCCH <NUM>, a PUSCH <NUM>, and/or an SRS <NUM> in the slot <NUM>. (In another example, rather than a single time slot, within a predetermined time period such as half a time slot, two time slots, a subframe, a mini-slot, several consecutive symbol periods, or an OFDM symbol period, the UE <NUM> may decide to transmit the preamble sequence <NUM> and be configured to transmit one or more of the PUCCH <NUM>, the PUSCH <NUM>, and the SRS <NUM>.

In this example, when the UE <NUM> transmits the preamble sequence <NUM>, the UE <NUM> is configured to use a default timing advance value. Accordingly, the UE <NUM> applies the default timing advance value to calculate a time point at which the transmission of the preamble sequence <NUM> is to be started.

On the other hand, as the UE <NUM> is in a connected state, the base station <NUM> has assigned a timing advance value to the UE <NUM> for uplink transmission. Accordingly, the UE <NUM> applies the assigned timing advance value to calculate a time point at which the transmission of the PUCCH <NUM>, the PUSCH <NUM>, or the SRS <NUM> is to be started.

The default timing advance value and the assigned timing advance value may not be the same. In certain configurations, the UE <NUM> does not have the capability to apply different timing advance values in a single time slot (e.g., the slot <NUM>) or in the predetermined time period described supra. In these scenarios, when the UE <NUM> transmits the preamble sequence <NUM> in the slot <NUM>, the UE <NUM> does not transmit the PUCCH <NUM>, the PUSCH <NUM>, and/or the SRS <NUM> in the slot <NUM> (or the predetermined time period). That is, the UE <NUM> refrains from transmitting the PUCCH <NUM>, the PUSCH <NUM>, and/or the SRS <NUM> in the slot <NUM> (or the predetermined time period).

In certain configurations, the UE <NUM> has the capability to apply different timing advance values in a single time slot (e.g., the slot <NUM>) or in the predetermined time period described supra. In these scenarios, the UE <NUM> may send an indication to the base station <NUM> to report the capability of the UE <NUM>. Further, when the UE <NUM> transmits the preamble sequence <NUM> in the slot <NUM> with the default timing advance value, the UE <NUM> may also transmit the PUCCH <NUM>, the PUSCH <NUM>, and/or the SRS <NUM> in the slot <NUM> (or the predetermined time period) with the assigned timing advance value.

In the above example, the preamble sequence <NUM> as well as the PUCCH <NUM>, the PUSCH <NUM>, and the SRS <NUM> are all transmitted on a same cell <NUM>. Further, in one configuration, the preamble sequence <NUM> as well as the PUCCH <NUM>, the PUSCH <NUM>, and the SRS <NUM> are all transmitted on a same uplink carrier. In another configuration, the preamble sequence <NUM> is transmitted on a first uplink carrier on the cell <NUM>, while the PUCCH <NUM>, the PUSCH <NUM>, and the SRS <NUM> are transmitted on a second, different uplink carrier.

In another example, the preamble sequence <NUM>' is transmitted on a cell <NUM> that is different from the cell <NUM>, while the PUCCH <NUM>, the PUSCH <NUM>, and the SRS <NUM> are transmitted on the cell <NUM>. Further, in one configuration, the cell <NUM> and the cell <NUM> are operated as intra-band carrier aggregation. In another configuration, the cell <NUM> and the cell <NUM> are operated as inter-band carrier aggregation.

<FIG> is a flow chart <NUM> of a method (process) for uplink transmission. The method may be performed by a UE (e.g., the UE <NUM>, the apparatus <NUM>, and the apparatus <NUM>'). At operation <NUM>, the UE determines to transmit a preamble sequence to a base station at a random access occasion in a random access procedure when the UE is in a connected state.

At operation <NUM>, the UE determines that the random access occasion is in a same predetermined time period as an uplink channel or a sounding reference signal that is scheduled to be transmitted to the base station.

At operation <NUM>, the UE determines whether the UE has capability to transmit a preamble sequence and an uplink channel or a sounding reference signal in the same predetermined time period. When the UE has the ability, at operation <NUM>, the UE transmits an indicator to the base station to indicate that the UE has the capability.

When the UE does not have the ability, at operation <NUM>, the UE refrains from transmitting the preamble sequence or refraining from transmitting the uplink channel or the sounding reference signal.

In certain configurations, the uplink channel is a PUCCH or a PUSCH. In certain configurations, the uplink channel or the sounding reference signal is refrained from transmitting. In certain configurations, the preamble sequence is refrained from transmitting. In certain configurations, the predetermined time period is a slot, a number of symbol periods, or a plurality of slots. In certain configurations, the random access occasion for the preamble sequence transmission is on a first cell, the uplink channel or the sounding reference signal is on a second cell, and the first cell is different from the second cell.

In certain configurations, the first cell and the second cell are operated as intra-band carrier aggregation. In certain configurations, the first cell and the second cell are operated as inter-band carrier aggregation. In certain configurations, the random access occasion is allocated on a first uplink carrier of a cell and the uplink channel or the sounding reference signal is scheduled on a second uplink carrier of the cell.

The apparatus <NUM> includes a reception component <NUM>, a capability component <NUM>, a RA component <NUM>, and a transmission component <NUM>.

The RA component <NUM> determines to transmit a preamble sequence to a base station at a random access occasion in a random access procedure when the UE is in a connected state. The RA component <NUM> determines that the random access occasion is in a same predetermined time period as an uplink channel or a sounding reference signal that is scheduled to be transmitted to the base station.

The capability component <NUM> determines whether the UE has capability to transmit a preamble sequence and an uplink channel or a sounding reference signal in the same predetermined time period. When the UE has the ability, the capability component <NUM> transmits an indicator to the base station to indicate that the UE has the capability.

When the UE does not have the ability, the RA component <NUM> refrains from transmitting the preamble sequence or refraining from transmitting the uplink channel or the sounding reference signal.

The processing system <NUM> may be implemented with a bus architecture, represented generally by a bus <NUM>.

The processing system <NUM> may be coupled to a transceiver <NUM>, which may be one or more of the transceivers <NUM>. The transceiver <NUM> is coupled to one or more antennas <NUM>, which may be the communication antennas <NUM>.

The transceiver <NUM> provides a means for communicating with various other apparatus over a transmission medium. The transceiver <NUM> receives a signal from the one or more antennas <NUM>, extracts information from the received signal, and provides the extracted information to the processing system <NUM>, specifically the reception component <NUM>. In addition, the transceiver <NUM> receives information from the processing system <NUM>, specifically the transmission component <NUM>, and based on the received information, generates a signal to be applied to the one or more antennas <NUM>.

The processing system <NUM> includes one or more processors <NUM> coupled to a computer-readable medium / memory <NUM>. The one or more processors <NUM> are responsible for general processing, including the execution of software stored on the computer-readable medium / memory <NUM>. The software, when executed by the one or more processors <NUM>, causes the processing system <NUM> to perform the various functions described supra for any particular apparatus. The computer-readable medium / memory <NUM> may also be used for storing data that is manipulated by the one or more processors <NUM> when executing software. The processing system <NUM> further includes at least one of the reception component <NUM>, the capability component <NUM>, the transmission component <NUM>, and the RA component <NUM>. The components may be software components running in the one or more processors <NUM>, resident/stored in the computer readable medium / memory <NUM>, one or more hardware components coupled to the one or more processors <NUM>, or some combination thereof. The processing system <NUM> may be a component of the UE <NUM> and may include the memory <NUM> and/or at least one of the TX processor <NUM>, the RX processor <NUM>, and the communication processor <NUM>.
