Techniques for adaptation of random access configuration in wireless communications

Abstract

Methods, systems, and devices for wireless communication are described that provide adaptation of a physical random access channel (PRACH) configuration to change a number of random access occasions (ROs) available for transmitting a random access message from a user equipment (UE) after a signal is received at the UE. The PRACH configuration can be adapted to provide an increased number of ROs for a duration after the signal is received at the UE. The timing for starting the adapted PRACH configuration can be at the start of a subsequent RO pattern within an association pattern period, at the start of a subsequent paging association pattern period, or a certain number of milliseconds or frames after signaling indicating the adapted PRACH configuration.

[0002] This patent application claims priority to U.S. non-provisional patent application No. 18 / 628,321, filed April 5, 2024, entitled “TECHNIQUES FORADAPTATION OF RANDOM ACCESS CONFIGURATION IN WIRELESS COMMUNICATIONS”, which is assigned to the assignee of this application and is expressly incorporated herein by reference in its entirety. Technical Field

[0003] The following content relates to wireless communication, including techniques for adapting random access configurations in wireless communication. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0005] The described techniques relate to methods, systems, devices, and apparatuses that improve techniques for adapting random access configurations in wireless communications. For example, the described techniques provide adaptation of the Physical Random Access Channel (PRACH) configuration to change the number of Random Access Opportunities (ROs) available for transmitting random access messages from the User Equipment (UE) after a signal is received at the UE. In some aspects, the number of ROs can be increased for the duration after a signal is received at the UE, which can reduce the latency for the UE to access a network entity in response to receiving the signal. In some aspects, signaling indicating the adaptation of the PRACH configuration can provide implicit indications (such as in paging messages (e.g., in the transmission of Early Paging Indicator (PEI), Paging Downlink Control Information (DCI), or Paging Physical Downlink Shared Channel (PDSCH))) or explicit indications (e.g., in a DCI providing an updated RO mode) that provide an updated RO mode. In some aspects, the timing for initiating the adapted or updated PRACH configuration may be at the beginning of a subsequent RO mode within the associated mode cycle, at the beginning of a subsequent paging associated mode cycle, or a certain number of milliseconds or frames after the signaling indicating the adapted PRACH configuration. In some aspects, the adapted PRACH configuration may be valid for subsequent RO modes within the paging associated mode cycle, the subsequent paging associated mode cycle may be valid until an updated PRACH configuration is provided, or be valid for a certain number of milliseconds or frames. In some cases, the DCI may indicate the updated mode of the RO within the PRACH associated mode cycle.

[0039] Wireless communication systems may include devices that support wireless communication using one or more radio access technologies, such as user equipment (UE) or network entities (e.g., evolved Node B (eNB), next-generation Node B, or gigabit Node B (any of which may be referred to as gNB), or some other base station or network entity). Examples of radio access technologies include 4G systems (such as LTE systems), 5G systems (which may be referred to as new radio (NR) systems), or other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein (e.g., sixth-generation (6G) systems and above).

[0040] In some wireless communication systems, such as fifth-generation (5G) or NR systems, network components may consume relatively large amounts of power in certain situations. For example, network entities (such as radio units (RUs) or radio heads) in systems using beamforming communications may transmit multiple directional beams in multiple directions. Such systems can provide information for user equipment (UEs) to use to access the wireless communication system using beam scanning techniques (e.g., system information providing parameters for system access), in which information is provided in multiple different transmissions in multiple different directions. Network entities may also monitor random access channel (RACH) timings (ROs) for random access messages transmitted from UEs, where RO patterns may include multiple ROs to be monitored, and different ROs may be associated with different beams.

[0041] In some cases, to reduce network power consumption, network entities may switch to a sleep mode or inactive mode where some or all of the transmit and receive circuits are powered down. For example, during off-peak hours, there may be no traffic or light traffic load in the cell, and network entities may stop or reduce periodic transmissions (e.g., SSB and SI transmissions) and periodic monitoring (e.g., monitoring of ROs, and / or monitoring of configured permitted uplink (CG) transmissions or small data transmission (SDT) communications), and switch to an inactive mode (e.g., where periodic activity periods are available for RO monitoring). In some cases, temporarily increasing the number of ROs available for the UE to send random access messages can be useful, such as when the UE is paged. Increasing the number of available ROs allows for reduced latency by enabling the UE to send RACH requests faster than when fewer ROs are available.

[0042] In current wireless communication systems (such as 5G systems), RO and RO modes can be configured in the Physical Random Access Channel (PRACH) configuration, which provides the RO mode within the RACH association period defined within the PRACH association mode period. To change the RO configured in such systems, a new PRACH configuration can be provided to the UE, which can be time-consuming and costly. Therefore, efficient signaling of an adapted RO mode that can be temporarily applied at the UE can be beneficial.

[0043] According to various aspects, techniques are provided for adapting PRACH configuration to change the number of ROs available for sending random access messages from the UE after an adaptation signal is received at the UE. In some aspects, the number of ROs can be increased for a duration after the adaptation signal is received at the UE, which can reduce the latency for the UE to access a network entity in response to receiving the signal. In some aspects, the signaling indicating the adaptation of PRACH configuration can provide an implicit indication (such as that provided by a paging message (e.g., in the transmission of an Early Paging Indicator (PEI), Paging Downlink Control Information (DCI), or Paging Physical Downlink Shared Channel (PDSCH))) or an explicit indication of the updated RO mode (e.g., a new DCI providing the updated RO mode). In some aspects, the timing for initiating the adapted PRACH configuration can be at the beginning of a subsequent RO mode within an associated mode period, at the beginning of a subsequent paging associated mode period, or a certain number of milliseconds or frames after the signaling indicating the adapted RO mode. In some respects, the adapted RO mode can be valid for subsequent RO modes within a paging association mode cycle, for subsequent paging association mode cycles, until an updated PRACH configuration is provided, or for a certain number of milliseconds or frames. In some cases, the new DCI can indicate the updated RO mode within a PRACH association mode cycle.

[0044] The aspects of this disclosure are first described in the context of a wireless communication system. The aspects of this disclosure are further illustrated and described with reference to resource diagrams, processing flows, device diagrams, system diagrams, and flowcharts of ROs relating to techniques for adapting random access configurations in wireless communication.

[0045] Figure 1 An example of a wireless communication system 100 is illustrated, which supports adaptation techniques for random access configuration in wireless communications according to one or more aspects of this disclosure. The wireless communication system 100 may include one or more devices (such as one or more network devices, e.g., network entity 105), one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0046] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via communication link 125 (e.g., a radio frequency (RF) access link). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish communication link 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0047] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Examples of UE 115 are illustrated herein. The UE 115 described herein may be able to support communication with various types of devices in the wireless communication system 100 (e.g., other wireless communication devices, including UE 115 or network entity 105), such as... Figure 1 As shown.

[0048] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. As another example, a node may be network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In still other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0049] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via backhaul communication link 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entity 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entity 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0050] One or more network entities or network equipment in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or gigabit NodeB (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home NodeB, home eNodeB, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity (e.g., network entity 105 or a single RAN node, such as base station 140).

[0051] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across multiple network entities (e.g., network entity 105) such as an Integrated Access and Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a Central Unit (CU) such as CU 160, a Distributed Unit (DU) such as DU 165, a Radio Unit (RU) such as RU 170, a RAN Intelligent Controller (RIC) such as RIC 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a Service Management and Orchestration (SMO) system such as SMO system 180, or any combination thereof. RU170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities in network entity 105 of a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0052] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 (e.g., one or more CUs) may connect to DU 165 (e.g., one or more DUs) or RU 170 (e.g., one or more RUs) or some combination thereof, and DU 165, RU 170, or both may host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and may each be at least partially controlled by CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between DU 165 and RU 170, such that DU 165 may support one or more layers of the protocol stack, and RU 170 may support one or more different layers of the protocol stack. DU 165 may (e.g., via one or more different RUs, such as RU 170) support one or more different cells. In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by corresponding network entities (e.g., one or more network entities in network entity 105) communicating via such communication links.

[0053] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities in network entity 105 (e.g., network entity 105 or IAB node 104) may be partially controlled by each other. IAB node 104 may be referred to as a donor entity or IAB donor. DU 165 or RU 170 may be partially controlled by CU 160 associated with network entity 105 or base station 140 (such as a donor network entity or donor base station). One or more donor network entities (e.g., IAB donors) may communicate with one or more additional devices (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DU 165) of a coupled IAB donor. The IAB-MT may be equipped with a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include one or more DUs (e.g., DU 165) that support communication links with a relay chain of the access network (e.g., downstream) or additional entities within the configuration (e.g., IAB node 104, UE 115). In such cases, one or more components of the decomposed RAN architecture (e.g., IAB node 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0054] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support the tests described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., components such as IAB node, DU 165, CU 160, RU 170, RIC 175, SMO system 180).

[0055] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0056] The UE 115 described herein can communicate with various types of devices, such as the UE 115 which sometimes operates as a relay, as well as network entity 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown.

[0057] UE 115 and network entity 105 can wirelessly communicate with each other via communication link 125 (e.g., one or more access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined PHY layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured to utilize multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “transmit,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the communication between network entity 105 of the RAN (e.g., base station 140, CU 160, DU 165, RU170) and another device (e.g., directly or via one or more other network entities, such as one or more network entities in network entity 105).

[0058] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0059] The time interval used for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, a multiple of a basic time unit. The sampling period is seconds, where It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval for organizing communication resources can be based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0060] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems, such as wireless communication system 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of the symbol period is related to the sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0061] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0062] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to transmit control information to UE115 (e.g., one or more UEs) or a UE-specific search space set configured to transmit control information to UE115 (e.g., a particular UE).

[0063] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas (such as coverage area 110). In some examples, coverage areas 110 associated with different technologies (e.g., different coverage areas) may overlap, but coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., network entity 105). In some other examples, overlapping coverage areas (such as coverage area 110) associated with different technologies may be supported by different network entities (e.g., network entity 105). The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 support communication for coverage area 110 (e.g., different coverage areas) using the same or different RATs.

[0064] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communications and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0065] In some examples, UE 115 may be configured to support direct communication with other UEs (one or more UEs in UE 115) via a device-to-device (D2D) communication link (such as D2D communication link 135) (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in the group performing D2D communication may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UEs 115 in this group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, the group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to one or more UEs in the group. In some examples, network entity 105 can facilitate the scheduling of resources used for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0066] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0067] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer waves in the lower frequencies (HF) or very high frequencies (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers).

[0068] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0069] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0070] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0071] In some cases, a PRACH configuration can be provided for UE 115, which indicates the mode of ROs available for transmitting RACH messages. Various aspects are described regarding adaptations to provide the PRACH configuration to change the number of ROs available for transmitting RACH messages from UE 115 after receiving an adaptation signal at UE 115. In some aspects, the number of ROs can be increased for the duration following the receipt of the adaptation signal at UE 115, which can reduce the latency for the UE to access network entities in response to receiving the signal.

[0072] Figure 2An example of a wireless communication system 200 is shown, which supports adaptation techniques for random access configuration in wireless communication according to one or more aspects of this disclosure. The wireless communication system 200 can implement as referenced herein. Figure 1 The described wireless communication system 100 may be implemented by or comprised of various aspects of these aspects. For example, wireless communication system 200 may include UE 115-a and network entity 105-a, which may be as referenced herein. Figure 1 Examples of UE 115 and network entity 105 are described. Wireless communication system 200 may support 3G, 4G, 5G or higher radio access technologies.

[0073] UE 115-a and network entity 105-a may perform wireless communication (e.g., one or more of the following actions: receiving, acquiring, transmitting or outputting control information, configuration information or data) via communication link 205 (including uplink communication link 205-a and downlink communication link 205-b), which may be as referenced herein. Figure 1 An example of a communication link 125 is described. In some cases, communication link 205 may include multiple component carriers. Figure 2 In this example, UE 115-a may be able to adapt the PRACH configuration and associated RO mode based on signals received from network entity 105-a. In such an example, UE 115-a may send a capability indication 210 to network entity 105-a indicating the ability to adapt the PRACH configuration. For example, capability indication 210 may indicate that UE 115-a is able to identify the modified RO for random access messages based on signals received at UE 115-a.

[0074] In some respects, network entity 105-a may send PRACH configuration 215 to UE 115-a, wherein PRACH configuration 215 indicates subframes that include RO according to RO mode. Figure 2 In the example, network entity 105-a may send an adaptation instruction 220 to UE 115-a, which may instruct PRACH configuration 215 to be updated to include a different number of ROs. For example, PRACH configuration 215 may be adapted from or changed from a first PRACH configuration with a first number of ROs to a second PRACH configuration with a second number of ROs. UE 115-a may use one or more of the ROs associated with the adapted PRACH configuration to send RACH message 225.

[0075] In some aspects, the number of ROs can be increased for the duration following the receipt of adaptation indication 220 at UE 115-a, which can reduce the latency for UE 115-a to access network entity 105-a in response to receiving the signal. In some aspects, adaptation indication 220 can be an implicit indication, for example, provided by a paging message (e.g., in PEI, paging DCI, or paging PDSCH transmission), or an explicit indication providing an updated RO mode (e.g., a DCI providing an updated RO mode). In some aspects, the timing for initiating the adapted PRACH configuration may be at the beginning of a PRACH association mode period following the PRACH association mode period in which adaptation indication 220 is received, at the beginning of a subsequent PRACH association period following the PRACH association period in which adaptation indication 220 is received, for a certain duration after receiving adaptation indication 220 (e.g., X milliseconds from the first symbol of adaptation indication 220), or for a certain number of frames after receiving adaptation indication 220 (e.g., X frames from the frame in which adaptation indication 220 is received). In some aspects, UE 115-a may start a timer associated with the adapted PRACH configuration based on receiving adaptation indication 220 (or within a specific time offset from receiving adaptation indication 220), and may interrupt the application of the adapted PRACH configuration when the timer expires. In some cases, the timer may have a timer value configured at UE 115-a (e.g., via RRC signaling). In some respects, UE 115-a can modify the system information cycle after receiving adaptation indication 220 (e.g., by SIB1 via...). modificationPeriodCoeff The adapted PRACH configuration is activated at the system information modification period (configured). In some aspects, the adapted PRACH configuration and associated RO mode can be valid until an updated PRACH configuration is provided (e.g., in an updated system information block (SIB)), until UE 115-a receives another indication of the updated PRACH configuration (e.g., another adaptation indication 220), for a certain duration from the start of the updated PRACH configuration (e.g., X milliseconds from the first symbol of the updated PRACH configuration), or for a certain number of frames (e.g., X frames after which UE 115-a reverts to the initially provided PRACH configuration 215).

[0076] In some respects, adaptation indication 220 may indicate an increase or decrease in the number of ROs. In some cases, the timeline for how long this adaptation will be effective may depend on the adaptation itself. For example, adding an additional RO may be effective for two frames, but removing an RO may be effective for one frame (e.g., because it will have a greater impact on latency). In some respects, if UE 115-a receives adaptation indication 220 that increases the number of ROs in the adapted PRACH configuration, UE 115-a may consider this indication to be effective for X frames, and if UE 115-a receives adaptation indication 220 that decreases the number of ROs in the adapted PRACH configuration, UE 115-a may consider this indication to be effective for Y frames, where X may be greater than or equal to Y. In other respects, adaptation may be effective until UE 115-a successfully sends RACH message 225, provided that the adaptation instruction 220 is implicitly provided (e.g., a paging instruction to increase the number of ROs) or where the adaptation instruction 220 also triggers UE 115-a to send RACH message 225 (e.g., until a response indicating that RACH message 225 was successfully received at network entity 105-a is received).

[0077] Additionally or alternatively, in some aspects, PRACH configurations may be adapted semi-statically. For example, implicit PRACH adaptation may be semi-static, such that the adapted PRACH configuration is applied until a subsequent signal for further updates to the PRACH configuration is received at UE 115-a. In some aspects, network entity 105-a may define periodic switching between two or more configurations. For example, a PRACH configuration 215 indicating two different PRACH configurations may be provided, and an adaptation indication 220 may indicate a change in the PRACH configuration used, or a change in the mode between two PRACH configurations. For example, a bitmap may be used for a set of frames to indicate the mode used for switching between two PRACH configurations, indicating which configuration to use (e.g., a 001001 indication, for which 0 means to follow the old configuration and 1 means to use the second configuration, etc.), or indicating which configuration is mapped to which frame values. Figures 3 to 5 Examples of RO modes based on various aspects of the technology discussed in this article are provided.

[0078] Figure 3 An example of RO mode 300 is shown, which supports adaptation techniques for random access configuration in wireless communication according to one or more aspects of this disclosure. In some cases, aspects of RO mode 300 may be implemented as described in the references. Figure 1 and Figure 2The described wireless communication system 100 or 200 may include or be implemented by these aspects. For example, RO mode 300 may be configured at network entity 105 and UE 115, which may be as described in the reference. Figure 1 and Figure 2 Examples of network entity 105 and UE 115 described.

[0079] In this example, a first PRACH configuration 305 can be configured at both the UE and the network entity, which can be adapted to a second PRACH configuration 310 via an adaptation indication. In this example, the first PRACH configuration 305 may include ROs 315, wherein each radio frame includes two ROs 315, such that two consecutive radio frames include a first RO 315-a, a second RO 315-b, a third RO 315-c, and a fourth RO 315-d. Furthermore, in this example, the second PRACH configuration 310 includes one RO 330 per radio frame, and therefore provides fewer ROs than the first PRACH configuration 305. In other examples, as will be readily understood, the second PRACH configuration 310 may include more ROs 330 than the first PRACH configuration 305. Figure 3 In the example, adaptation indication 320 may be received during the first radio frame, and timeline 325 for initiating the second PRACH configuration 310 may be in the second frame after receiving adaptation indication 320. In some cases, timeline 325 for updating PRACH configuration may be configured at the UE (e.g., via RRC signaling), or may be a timeline defined for a UE capable of performing such PRACH adaptation. As discussed herein, in some aspects, the second PRACH configuration 310 resumes the first PRACH configuration 305 for a defined duration (e.g., a number of radio frames or milliseconds), such as... Figure 4 (As illustrated in the example) can be valid, or it can remain valid until a subsequent signal for further updates to the PRACH configuration is received.

[0080] Figure 4 Another example of RO mode 400, which supports adaptation techniques for random access configuration in wireless communication according to one or more aspects of this disclosure, is shown. In some cases, aspects of RO mode 400 may be implemented as described in the references. Figure 1 and Figure 2 The described wireless communication system 100 or 200 includes or is implemented by these aspects. For example, RO mode 400 can be configured at network entity 105 and UE 115, which can be as described in the reference. Figure 1 and Figure 2 Examples of network entity 105 and UE 115 described.

[0081] In this example, a first PRACH configuration 405 can be configured at the UE and network entity, which can be adapted to a second PRACH configuration 410 via an adaptation indication. In this example, the first PRACH configuration 405 may include ROs 415, wherein each radio frame includes two ROs 415, such that the initial two consecutive radio frames include a first RO 415-a, a second RO 415-b, a third RO 415-c, and a fourth RO 415-d, and the fifth radio frame following the second PRACH configuration 410 includes a fifth RO 415-e and a sixth RO 415-f. Furthermore, in this example, the second PRACH configuration 410 includes one RO 430 per radio frame, and therefore the second PRACH configuration 410 provides a first RO 430-a in the third radio frame and a second RO 430-b in the fourth radio frame. In other examples, as will be readily understood, the second PRACH configuration 410 may include more ROs 430 than the first PRACH configuration 405. Figure 4 In this example, adaptation indication 420 may be received during the first radio frame, and the timeline 425 for initiating the second PRACH configuration 410 may be the second frame after receiving adaptation indication 420. In this example, the second PRACH configuration 410 may be valid for two radio frames, and therefore in this example, a first instance of the first PRACH configuration 405-a may be applied to the first and second radio frames, the second PRACH configuration 410 may be applied to the third and fourth radio frames, and a second instance of the first PRACH configuration 405-b may be applied to the fifth and subsequent radio frames.

[0082] Figure 5 Another example of RO mode 500, which supports adaptation techniques for random access configuration in wireless communication according to one or more aspects of this disclosure, is shown. In some cases, aspects of RO mode 500 may be implemented as described in the references. Figure 1 and Figure 2 The described wireless communication system 100 or 200 includes or is implemented by these aspects. For example, RO mode 500 can be configured at network entity 105 and UE 115, which can be as described in the reference. Figure 1 and Figure 2 Examples of network entity 105 and UE 115 described.

[0083] In this example, a pattern of PRACH configurations including a first PRACH configuration 505 and a second PRACH configuration 510 may be provided. In some cases, an adaptation indication (e.g., indicating which configuration should be used for the DCI of which radio frames) may be provided, indicating which PRACH configuration should be used for each frame in a set of radio frames. For example, the adaptation indication may indicate a pattern applied to a set of consecutive radio frames (such as six radio frames in this example). This pattern may indicate that the first PRACH configuration 505 is applied to the first radio frame, the second radio frame, the fourth radio frame, and the fifth radio frame, wherein the first PRACH configuration 505 provides two ROs 515 per frame. Furthermore, in this example, the pattern may indicate that the second PRACH configuration 510 is applied to the third and sixth radio frames, wherein the second PRACH configuration 510 provides one RO 520 per frame. The pattern can be indicated by network entities, such as by using a sequence of configuration patterns indicating the set of frames (e.g., a sequence value of 112112), by using a bitmap indicating which configuration is applied to each frame in the set of frames (e.g., a bitmap of 001001 indicating the application of the configured or adapted PRACH configuration), or by using index values ​​mapped to the pattern (e.g., two-bit index values, where each bit value is mapped to a different sequence of PRACH configurations for the set of frames). Such examples are described for illustrative and discussion purposes only, and numerous other examples of patterns and pattern indications are available in accordance with the techniques discussed herein.

[0084] continue Figure 5 For example, a first instance of the first PRACH configuration 505-a can be applied to a first frame including a first RO 515-a and a second RO 515-b. A second instance of the first PRACH configuration 505-b can be applied to a second frame including a third RO 515-c and a fourth RO 515-d. A first instance of the second PRACH configuration 510-a can be applied to a third frame including a first RO 520-a of the second PRACH configuration 510-a. A third instance of the first PRACH configuration 505-c can be applied to a fourth frame including a fifth RO 515-e and a sixth RO 515-f, and a fourth instance of the first PRACH configuration 505-d can be applied to a sixth frame including a seventh RO 515-g and an eighth RO 515-h. Finally, in this example, a second instance of the second PRACH configuration 510-b can be applied to a sixth frame including a second RO 520-b of the second PRACH configuration 510-b. In this way, the number of ROs available for RACH messages can be selected to provide efficient transmission of RACH messages, and the latency for such RACH messages can be provided to suit the type of communication between the UE and the network entity.

[0085] Figure 6An example of a process flow 600 supporting an adaptation technique for random access configuration in wireless communication, according to one or more aspects of this disclosure, is shown. In some cases, aspects of process flow 600 may be implemented as described in the references. Figures 1 to 5 The described wireless communication system 100 or 200, or aspects of random access resources, or implementations thereof. For example, process flow 600 may include UE 115-b, which may be as described in reference... Figures 1 to 5 An example of UE 115 is described. Additionally, process flow 600 may include network entity 105-b, which may be as described in the reference... Figures 1 to 5 An example of network entity 105 described.

[0086] In the following description of process flow 600, operations may be performed in a different order than those shown. Additionally or alternatively, other operations may be added to or removed from process flow 600. Although UE 115-b and network entity 105-b are shown performing operations of process flow 600, some aspects of some operations may be performed by one or more other devices (e.g., other UE 115, other network entity 105, or other entities outside the network).

[0087] At 605, optionally, UE 115-b can send and network entity 105-b can receive a UE capability indication. In some cases, the UE capability indication may be provided via RRC signaling along with other UE 115-b capabilities. In some cases, the UE capability indication may be provided in response to a query from network entity 105-b. In some cases, according to techniques discussed herein, the UE capability indication may indicate that UE 115-b is capable of identifying and adapting the PRACH configuration and RO for random access messages.

[0088] At 610, network entity 105-b can send and UE 115-b can receive PRACH configuration. In some cases, the PRACH configuration can indicate the PRACH configuration index value of a parameter mapped to the location defining the RO.

[0089] At point 615, network entity 105-b can send and UE 115-b can receive an adaptation indication. In some cases, the adaptation indication may indicate a different PRACH configuration to be used for RACH messages between UE 115-b and network entity 105-b. In some cases, the adaptation indication may be provided in a paging message, which implicitly indicates that the PRACH configuration should be adapted to provide additional ROs compared to a previously provided PRACH configuration. In other cases, the adaptation indication may be an explicit indication provided in DCI communications, which indicates a specific PRACH configuration or a pattern of PRACH configurations to be applied to a series of radio frames.

[0090] At 620, UE 115-b can determine the resources for one or more adapted ROs based on PRACH configuration and adaptation indication. UE 115-b can determine the location of the adapted RO in one or more radio frames according to various techniques as discussed herein, including the determination of time / frequency resources for one or more ROs. At 625, network entity 105-b can monitor RACH messages in one or more ROs based on the location of the adapted RO.

[0091] At 630, UE 115-b can send and network entity 105-b can receive RACH messages (e.g., MSG1) in the RO available according to the adapted PRACH configuration. At 635, UE 115-b and network entity 105-b can communicate using an established communication procedure triggered by the RACH message.

Random access transmission component 835 is capable of, configured to, or operable to support components for transmitting at least a first random access message in a first RO determined based on the second random access configuration.

[0106] Figure 9A block diagram 900 of a communication manager 920 supporting adaptation techniques for random access configuration in wireless communication according to one or more aspects of this disclosure is shown. The communication manager 920 may be an example of aspects of the communication manager 720, communication manager 820, or both as described herein. The communication manager 920 or its various components may be examples of components for performing various aspects of the techniques for random access configuration adaptation in wireless communication as described herein. For example, the communication manager 920 may include a random access configuration manager 925, a random access adaptation manager 930, a random access transmission component 935, or any combination thereof. Each of these components, or its components or sub-components (e.g., one or more processors, one or more memories), may communicate directly or indirectly with each other (e.g., via one or more buses).

[0107] Communication manager 920 may support wireless communication according to examples disclosed herein. Random access configuration manager 925 is capable of, configured to, or operable to support components for receiving a first signal indicating a first random access configuration, the first random access configuration including a first mode of one or more ROs available for transmission of random access messages from the UE during a random access configuration period. Random access adaptation manager 930 is capable of, configured to, or operable to support components for receiving a second signal indicating a second random access configuration during a random access configuration period, the second random access configuration being an adaptation of the first random access configuration to be applied for a duration beginning at a first time relative to the reception time of the second signal. Random access transmission component 935 is capable of, configured to, or operable to support components for transmitting at least a first random access message in a first RO determined based on the second random access configuration. In some examples, the second random access configuration provides one or more additional ROs compared to those initially provided in the first random access configuration.

[0108] In some examples, to support the reception of a second signal, the random access adapter manager 930 can be configured or operable to support components for receiving one or more of the following: paging early indication, paging DCI transmission, paging downlink shared channel transmission, or DCI transmission providing an updated mode of the RO within the random access configuration period. In some examples, the random access adapter manager 930 can be configured or operable to support components for applying a second random access configuration to one or more random access association mode periods following the random access association mode period in which the second signal is received.

In some examples, the random access adapter manager 930 is capable of, configured to, or operable to support components for initiating the application of the second random access configuration at a defined number of radio frames following the receipt of the second signal.

[0110] In some examples, the second random access configuration is applied until an updated system information block is received at the UE. In some examples, the second random access configuration is applied until another signal updating the first random access configuration is received at the UE after the second signal. In some examples, the second random access configuration is applied for a defined duration or a defined number of radio frames after the second signal is received at the UE. In some examples, the second random access configuration is applied for a defined number of random access association mode periods or random access association periods within a random access association mode period. In some examples, when an increase in the number of ROs is indicated, the second random access configuration is applied for a first duration, and when a decrease in the number of ROs is indicated, the second random access configuration is applied for a second duration, wherein the first duration is different from the second duration.

Code 1035 may be stored in a non-transitory computer-readable medium such as system memory or another type of memory. In some cases, code 1035 may not be directly executable by at least one processor 1040, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, at least one memory 1030 may include a basic I / O system (BIOS), etc., which controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0116] At least one processor 1040 may include one or more intelligent hardware devices (e.g., one or more general-purpose processors, one or more DSPs, one or more CPUs, one or more graphics processing units (GPUs), one or more neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DLPs)), one or more microcontrollers, one or more ASICs, one or more FPGAs, one or more programmable logic devices, discrete gate or transistor logic, one or more discrete hardware components, or any combination thereof). In some cases, at least one processor 1040 may be configured to use a memory controller to operate a memory array. In some other cases, the memory controller may be integrated into at least one processor 1040. At least one processor 1040 may be configured to execute computer-readable instructions stored in memory (e.g., at least one memory 1030) to cause device 1005 to perform various functions (e.g., functions or tasks that support adaptation techniques for random access configurations in wireless communications). For example, device 1005 or components thereof may include at least one processor 1040 and at least one memory 1030 coupled to or coupled to the at least one processor 1040, the at least one processor 1040 and the at least one memory 1030 being configured to perform the various functions described herein.

[0117] In some examples, at least one processor 1040 may include multiple processors, and at least one memory 1030 may include multiple memories. One or more of the multiple processors may be coupled to one or more of the multiple memories, which may be configured individually or collectively to perform the various functions described herein.

The processing system may be configured to perform one or more of the functions described herein. For example, at least one processor 1040 or a processing system including at least one processor 1040 may be configured, configured to, or operable to cause device 1005 to perform one or more of the functions described herein. Furthermore, as described herein, “configured to,” “capable of being configured to,” and “capable of operating to” are used interchangeably and may be associated with the ability to perform one or more of the functions described herein when executing code 1035 (e.g., processor-executable code) stored in at least one memory 1030 or otherwise.

[0118] The communication manager 1020 may support wireless communications according to examples disclosed herein.

Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0225] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0226] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, searching (such as by searching in a table, database, or other data structure), ascertainment, etc. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, acquiring, selecting, choosing, creating, and other similar actions.

[0227] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second numeral for differentiation between similar components. If only the first reference numeral is used in the specification, the description applies to any of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0228] The description herein, illustrated in conjunction with the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some of the drawings, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0229] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
