Description
SWITCHING BETWEEN PHYSICAL DOWNLINK CONTROL CHANNEL MONITORING MODES
[0001] FIELD OF THE DISCLOSURE
[0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with switching between physical downlink control channel (PDCCH) monitoring modes.
[0003] DESCRIPTION OF RELATED ART
[0004] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and / or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and / or device transmit power, among other examples) . Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level.
[0005] An example telecommunication standard is New Radio (NR) . NR, which may also be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . NR (and other RATs beyond NR) may be designed to better support enhanced mobile broadband (eMBB) access, Internet of things (IoT) networks or reduced capability device deployments, and ultra-reliable low latency communication (URLLC) applications. To support these verticals, NR systems may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO) , licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to-everything (CV2X) communication) , multiple-subscriber implementations, high-precision positioning, and / or radio frequency (RF) sensing, among other examples. As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases.SUMMARY

The present disclosure is not to be construed as limited to any specific aspect illustrated by or described with reference to an accompanying drawing or otherwise presented in this disclosure.

[0024] Several aspects of telecommunication systems will now be presented with reference to various methods, operations, apparatuses, and techniques. These methods, operations, apparatuses, and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0025] In some examples, a user equipment (UE) may be equipped with a main radio (MR) and a low power wake-up radio (LP-WUR) . The LP-WUR may be a companion receiver that can be used with the MR to reduce power consumption of the UE. The LP-WUR may be a simple radio receiver circuit designed to have a very low energy consumption. The UE may use the MR to transmit and / or receive data (e.g., to and / or from a network node or another UE) , and the MR may be turned off or operated in a low power state (or sleep state) , such as an ultra-low power state (ULPS) or a deep sleep state, unless there is data to transmit and / or receive. For example, the LP-WUR may monitor configured low power wake-up signal (LP-WUS) monitoring occasions, and a network node may transmit an LP-WUS to the UE in an LP-WUS monitoring occasion to indicate that there is data to be received by the UE. When there is no data for the UE to receive, the LP-WUR may not detect / receive the LP-WUS, and the MR may remain in the low power state (e.g., ULPS) unless there is data for the UE to transmit. When there is data for the UE to receive, the LP-WUR may receive the LP-WUS in an LP-WUS monitoring occasion and may activate the MR (e.g., the LP-WUR may trigger activation of the MR by the UE when the LP-WUR receives the LP-WUS) . The data may then be transmitted (e.g., by the network node) and received by the MR of the UE. In some examples, the LP-WUR may be an ultra-low power wake-up receiver that triggers activation of the MR from the ULPS.
[0026] One application for the LP-WUS is to reduce unnecessary UE paging receptions. In this case, a network node may transmit the LP-WUS to an idle or inactive mode UE (e.g., a UE operating in a radio resource control (RRC) idle mode or an RRC inactive mode) only if there is paging for the idle or inactive mode UE. The LP-WUR of the idle or inactive mode UE may monitor for the LP-WUS in LP-WUS occasions (e.g., while the UE is operating in the idle or inactive mode) . If the LP-WUS is detected by the LP-WUR of the idle or inactive mode UE, the MR may be turned on (e.g., activated) , and the MR may monitor for a synchronization signal block (SSB) for synchronization prior to a paging occasion. The MR may then receive the paging in the paging occasion. If the LP-WUS is not detected by the LP-WUR of the idle or inactive mode UE, the MR may remain in a deep sleep or ULPS mode for power saving. In some examples, low power synchronization signals (LP-SSs) may be transmitted by the network node periodically to assist the LP-WUR of the UE with time and / or frequency synchronization. Because the UE, while in the idle or inactive mode, may perform radio resource management (RRM) measurements for mobility purposes, such as cell reselection and / or handover, among other examples, the UE may not be able to save much power if the MR has to frequently wake up to perform such RRM measurements. In some examples, to alleviate this issue, the LP-SSs may be used (e.g., by the LP-WUR of the UE) for measurement purposes while the MR remains in the deep sleep mode.
[0027] In some examples, discontinuous reception (DRX) cycle (e.g., connected mode DRX (C-DRX) ) may be configured for the UE to reduce power consumption of the UE. When DRX is configured for the UE, the UE (e.g., the MR of the UE) may not continuously monitor for PDCCH (e.g., monitor for PDCCH transmissions) . The DRX (e.g., C-DRX) cycle may provide off durations (sometimes referred to as inactive times, or sleep durations) in which the UE (e.g., the MR of the UE) is inactive (e.g., in a sleep state) and on durations in which the UE (e.g., the MR of the UE) is active to monitor for PDCCH. The UE may monitor for a PDCCH during the on duration. That is, the on duration may be a duration that the UE waits, after waking up, to receive PDCCHs. If the UE does not receive a PDCCH during the on-duration, the off duration may begin, and the UE may return to the sleep state. If the UE receives (e.g., and successfully decodes) a PDCCH during the on-duration, the UE may remain awake (e.g., active) and start an inactivity timer. The UE may continue to monitor for PDCCH while the inactivity timer is running. The inactivity timer may be a duration, from a last successful decoding of a PDCCH, that the UE waits to receive (e.g., and successfully decode) another PDCCH. If the UE does not receive a PDCCH prior to the expiry of the inactivity timer, the UE may return to the sleep state. If the UE receives a PDCCH while the inactivity timer is running, the UE may restart the inactivity timer. For example, the UE may restart the inactivity timer following a single successful decoding of a PDCCH for a first transmission only (e.g., not for retransmissions) . A retransmission timer may be a duration in which a retransmission of a PDCCH can be expected. The UE may start the retransmission time when expecting a retransmission of a PDCCH, and the UE may monitor for PDCCH while the retransmission timer is running. The DRX cycle (e.g., the C-DRX cycle) may specify the periodic repetition of the on duration followed by a possible period of inactivity (e.g., the off duration) . The active time for a UE may be a total duration that the UE monitors for PDCCH, including the on duration of the DRX cycle, the time in which the UE is performing continuous reception (e.g., monitoring for PDCCH) while the inactivity timer has not expired, and the time in which the UE is performing continuous reception (e.g., monitoring for PDCCH) while waiting for a retransmission opportunity.
[0028] In some examples, PDCCH monitoring by a UE (e.g., by the MR of the UE) may be triggered by downlink control information (DCI) with cyclic redundancy check (CRC) scrambled by power saving radio network temporary identifier (PS-RNTI) (DCP) . In this case, the UE may be configured to monitor for DCP when C-DRX is configured for the UE. The UE may be configured with one or more DCP monitoring occasions before each on duration in the C-DRX cycle. The UE (e.g., the MR of the UE) may monitor for DCP in the DCP monitoring occasions. The network node may transmit a DCP to the UE in a DCP monitoring occasion to indicate that the UE is to monitor for PDCCH during the next occurrence of the on duration in the C-DRX cycle. Accordingly, if the UE detects / receives a DCP in a DCP monitoring occasion, the UE may monitor for PDCCH in the next occurrence of the on duration in the C-DRX cycle. If the UE does not detect / receive a DCP, the UE may not monitor for PDCCH during the next occurrence of the on duration in the C-DRX cycle (e.g., unless the UE is otherwise explicitly configured to monitor for PDCCH in that on duration) . In some examples, when carrier aggregation (CA) is configured, DCP may be configured only on a primary cell (PCell) .
[0029] In some examples, the LP-WUS / LP-WUR may be implemented in conjunction with DRX (e.g., C-DRX) for a UE operating in a connected mode (e.g., an RRC connected mode) . In such examples, the LP-WUS may be used to trigger PDCCH monitoring by the MR of the UE operating in the connected mode to reduce unnecessary PDCCH monitoring by the MR of the UE, which may further reduce power consumption of the UE as compared with non-LP-WUS-based PDCCH monitoring (e.g., legacy PDCCH monitoring) with or without DCP configured. In various examples, there may be multiple options for how the LP-WUS is used (e.g., in conjunction with C-DRX) to trigger the UE (e.g., the MR of the UE) to monitor for PDCCH.
[0030] In a first option (referred to herein as “Option 1” ) , the LP-WUS triggers PDCCH monitoring in PDCCH occasions in an active time of the DRX cycle. That is, in Option 1, the LP-WUR of the UE may monitor for the LP-WUS in an LP-WUS monitoring occasion (or LP-WUS monitoring window) configured prior to the on duration in each DRX cycle. For example, the LP-WUS monitoring occasion / window may be at least a certain offset before a slot in which the on duration (e.g., drx-onDurationTimer) would start. A network node may transmit the LP-WUS to the UE in the LP-WUS monitoring occasion / window to notify the UE that the UE is to monitor for PDCCH in the DRX active time (e.g., the on duration) of the DRX cycle. Accordingly, if the LP-WUR of the UE receives / detects the LP-WUS in the LP-WUS monitoring occasion / window, the UE may activate the MR and the MR of the UE may monitor for PDCCH in the next on duration (e.g., the next active time) of the DRX cycle For example, the MR of the UE may monitor the active time of drx-onDurationTimer configured for long DRX in connection with the LP-WUR of the UE receiving the LP-WUS in the LP-WUS monitoring occasion / window.
[0031] In a second option (referred to herein as “Option 2” ) , the LP-WUS triggers PDCCH monitoring in PDCCH occasions independent of an active time of the DRX cycle. That is, in Option 2, the LP-WUR of the UE may monitor for the LP-WUS in LP-WUS monitoring occasions configured for the UE, and the LP-WUS may trigger the MR of the UE to monitor for PDCCH in a PDCCH occasion that is independent of the active time (e.g., the on duration) in the DRX cycle configured for the UE. For example, the LP-WUS (e.g., if received / detected by the LP-WUR of the UE) may trigger PDCCH monitoring by the MR of the UE in a PDCCH occasion offset from the LP-WUS reception / detection (or offset from the LP-WUS monitoring occasion) by a certain offset. Accordingly, in Option 2, the MR of the UE may monitor for PDCCH in a PDCCH occasion, after the LP-WUR of the UE successfully detects the LP-WUS, irrespective of the PDCCH occasion being outside or inside of the PDCCH active time window defined by the DXR configuration. In some examples, in Option 2, when the MR of the UE monitors for PDCCH in the PDCCH occasion based on receiving the LP-WUS, the UE (e.g., the MR of the UE) may additionally monitor for PDCCH in the PDCCH occasions (e.g., the legacy PDCCH occasions) defined by the on durations of the DRX cycle. In some other examples, in Option 2, when the MR of the UE monitors for PDCCH in the PDCCH occasion based on receiving the LP-WUS, the UE may skip monitoring for PDCCH in the PDCCH occasions (e.g., the legacy PDCCH occasions) defined by the on durations of the DRX cycle (e.g., the PDCCH occasions within the active time of drx-onDurationTimer configured for long DRX) .
[0032] In some examples, a coverage area for an LP-WUS transmitted by a network node may be smaller than a coverage area for PDCCH transmissions from the network node. When a UE is in the coverage area of the LP-WUS, the UE may enter an LP-WUS-based PDCCH monitoring mode and follow the LP-WUS indication for PDCCH monitoring (e.g., in accordance with Option 1 or Option 2) . When the UE is out of the coverage area of the LP-WUS, the UE may fall back to a non-LP-WUS-based PDCCH monitoring mode (e.g., legacy PDCCH monitoring) with or without DCP. For Option 1 (e.g., an LP-based PDCCH monitoring mode associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions in an active time of a DRX cycle) , when the UE falls back to non-LP-WUS-based PDCCH monitoring, the network node may not know that the UE has moved outside of LP-WUS coverage, and the network node may continue to transmit the LP-WUS to the UE. However, the UE will not receive the LP-WUS, and the transmission of the LP-WUS by the network node results in unnecessary power consumption by the network node. Furthermore, because DCP and Option 1 for LP-WUS-based PDCCH monitoring cannot be used together, DCP may not be used for the UE when the UE falls back to non-LP-WUS based PDCCH monitoring from Option 1. Accordingly, the UE may be prevented using DCP based PDCCH monitoring to reduce power consumption in the non-LP-WUS-based PDCCH monitoring mode.
[0033] For Option 2 (e.g., an LP-WUS-based PDCCH monitoring mode associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions independent of an active time of a DRX cycle) , when the UE falls back to non-LP-WUS-based PDCCH monitoring, the UE may monitor for PDCCH in the configured DRX on duration window. However, the network node may transmit a PDCCH in a PDCCH occasion associated with the LP-WUS instead of during the configured DRX on duration window, resulting in the UE not receiving the PDCCH. As a result, reliability may be decreased and latency may be increased for communications between the network node and the UE.
[0034] In some examples, when the UE moves into the coverage area of the LP-WUS and enters the LP-WUS-based PDCCH monitoring mode, the network node may not be aware that the UE is in the LP-WUS coverage. Accordingly, the network node may not transmit the LP-WUS to the UE, which may result in the UE unnecessarily monitoring for the LP-WUS and / or the UE not receiving a PDDCH (due to the LP-WUR of the UE not receiving the LP-WUS and the UE not activating to the MR to monitor for the PDCCH) transmitted to the UE by the network node. Accordingly, the UE may not achieve a reduction of power consumption associated with the LP-WUS-based PDCCH mode, and / or reliability may be decreased and latency may be increased for communications between the network node and the UE.
[0035] Various aspects relate generally to switching between PDCCH monitoring modes for a UE. Some aspects more specifically relate to switching between an LP-WUS-based PDCCH monitoring mode and a non-LP-WUS-based PDCCH monitoring mode. In some aspects, a UE may switch from a first PDCCH monitoring mode to a second PDCCH monitoring mode in accordance with a switching condition. The UE may transmit, to a network node, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode. In some aspects, the network node may transmit, and the UE may receive, from the network node, a switching command indicating for the UE to switch from the first PDCCH monitoring mode to the second PDCCH monitoring mode, and the UE may switch from the first PDCCH monitoring mode to the second PDCCH monitoring mode in connection with receiving the switching command. In some aspects, the first PDCCH monitoring mode may be an LP-WUS-based PDCCH monitoring mode, and the second PDCCH monitoring mode may be a non-LP-WUS-based PDCCH monitoring mode. In some examples, the first PDCCH monitoring mode may be an LP-WUS-based PDCCH monitoring mode associated with Option 1 (e.g., associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions in an active time of a DRX cycle) , and the second PDCCH monitoring mode may be a non-LP-WUS-based PDCCH monitoring mode configured with or without DCP. In some other examples, the first PDCCH monitoring mode may be an LP-WUS-based PDCCH monitoring mode associated with Option 2 (e.g., associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions independent of an active time of a DRX cycle) , and the second PDCCH monitoring mode may be a non-LP-WUS-based PDCCH monitoring mode configured with or without DCP. In some aspects, the first PDCCH monitoring mode may be a non-LP-WUS-based PDCCH monitoring mode, and the second PDCCH monitoring mode may be an LP-WUS-based PDCCH monitoring mode. In some aspects, the first PDCCH monitoring mode may be a first LP-WUS-based PDCCH monitoring mode associated with a first LP-WUS configuration, and the second PDCCH monitoring mode may be a second LP-WUS-based PDCCH monitoring mode associated with a second LP-WUS configuration.
[0036] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by the UE transmitting, to a network node, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode, the described techniques can be used to enable coordination, between the UE and the network node, of the switch from the first PDDCH monitoring mode to the second PDCCH monitoring mode for the UE. This enables the network node to be aware of the UE switching to the second PDCCH monitoring mode for the UE, and thus, to use the correct signaling (e.g., LP-WUS or DCP) to notify the UE of PDCCH monitoring and / or PDCCH occasions to transmit PDCCH transmissions for the UE. As a result, power consumption may be reduced at the network node and / or the UE, reliability for communications between the network node and the UE may be increased, and latency for communications between the network node and the UE may be decreased.
[0037] In some examples, by the UE receiving the switching command from the network node, and the UE switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode in connection with receiving the switching command, the described techniques can be used to enable the network node to synchronize the switch from the first PDCCH monitoring mode to the second PDCCH monitoring mode by the UE, and a corresponding switch of PDCCH occasions and / or signaling, to notify the UE of PDCCH monitoring used by the network node, which may result in a further reduction of power consumption at the network node and / or the UE, a further increase in reliability for communications between the network node and the UE, and / or a further decrease in latency for communications between the network node and the UE.
[0038] In some examples, by the UE transmitting the indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode, where the first PDCCH monitoring mode is an LP-WUS-based PDCCH monitoring mode associated with Option 1 (e.g., associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions in an active time of a DRX cycle) , and the second PDCCH monitoring mode is a non-LP-WUS-based PDCCH monitoring mode, the described techniques can be used to reduce power consumption at the network node due to unnecessary transmission of an LP-WUS to the UE when the UE switches from the LP-WUS-based PDCCH monitoring mode associated with Option 1 the non-LP-WUS-based PDCCH monitoring mode. Furthermore, by the UE receiving the switch command and switching from the LP-WUS-based PDCCH monitoring mode associated with Option 1 to the non-LP-WUS-based PDCCH monitoring mode in connection with receiving the switching command, the described techniques can be used to enable the UE to perform DCP triggered PDCCH monitoring when the UE switches to the non-LP-WUS-based PDCCH monitoring mode. As a result, power consumption at the UE, while operating in the non-LP-WUS-based PDCCH monitoring mode, may be reduced as compared with non-LP-WUS-based PDCCH monitoring mode without DCP.
[0039] In some examples, by the UE transmitting the indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode, where the first PDCCH monitoring mode is an LP-WUS-based PDCCH monitoring mode associated with Option 2 (e.g., associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions independent of an active time of a DRX cycle) , and the second PDCCH monitoring mode is a non-LP-WUS-based PDCCH monitoring mode, the described techniques can be used to reduce PDCCHs transmitted in PDCCH occasions no longer monitored by the UE when the UE switches to the non-LP-WUS-based PDCCH monitoring mode. As a result, reliability may be increased and latency may be decreased for communications between the network node and the UE when the UE switches from the LP-WUS-based PDCCH monitoring mode associated with Option 2 to the non-LP-WUS-based PDCCH monitoring mode.
[0040] In some examples, by the UE transmitting the indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode, where the first PDCCH monitoring mode is a non-LP-WUS-based PDCCH monitoring mode and the second PDCCH monitoring mode is an LP-WUS-based PDCCH monitoring mode, the described techniques can be used to enable the network node to begin transmission of an LP-WUS to the UE, reduce unnecessary LP-WUS monitoring by the UE, and reduce PDCCHs transmitted in PDCCH occasions not monitored by the UE when the UE switches to the LP-WUS-based PDCCH monitoring mode. As a result, power consumption at the UE may be reduced when the UE switches from the non-LP-WUS-based PDCCH monitoring mode to the LP-WUS-based PDCCH monitoring mode. Furthermore, reliability may be increased and latency may be decreased for communications between the network node and the UE when the UE switches from the non-LP-WUS-based PDCCH monitoring mode to the LP-WUS-based PDCCH monitoring mode.
[0041] In some examples, by the UE transmitting the indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode, where the first PDCCH monitoring mode is a first LP-WUS-based PDCCH monitoring mode associated with a first LP-WUS configuration, and the second PDCCH monitoring mode is a second LP-WUS-based PDCCH monitoring mode associated with a second LP-WUS configuration, the described techniques can be used to enable coordination, between the UE and the network node, of switching between different LP-WUS configurations for the UE. In this way, when the UE is out of coverage of a first LP-WUS associated with the first LP-WUS configuration and the UE is in coverage of a second LP-WUS associated with the second LP-WUS configuration, the UE may switch to the second LP-WUS configuration, and power consumption at the UE may be reduced (e.g., as compared with the UE switching to a non-LP-WUS-based PDCCH monitoring mode) .
[0042] As described above, wireless communication systems may be deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and / or other traffic. Some wireless communications systems may employ multiple-access radio access technologies (RATs) . The multiple-access RATs may be capable of supporting communication with multiple wireless communication devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and / or device transmit power, among other examples) . Examples of such multiple-access RATs include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0043] Multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable wireless communication devices to communicate on a local, municipal, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . 5G NR may support enhanced mobile broadband (eMBB) access, Internet of Things (IoT) networks or reduced capability (RedCap) device deployments, ultra-reliable low-latency communication (URLLC) applications, and / or massive machine-type communication (mMTC) , among other examples.
[0044] To support these and other target verticals, a wireless communication system may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO) , beamforming, IoT device or RedCap device connectivity and management, industrial connectivity, licensed and unlicensed spectrum access, sidelink and other device-to-device direct communication (for example, cellular vehicle-to-everything (CV2X) communication) , frequency spectrum expansion, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, device aggregation, advanced duplex communication (for example, sub-band full-duplex (SBFD) ) , multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, network energy savings (NES) , low-power signaling and radios, and / or artificial intelligence or machine learning (AI / ML) , among other examples.
[0045] The foregoing and other technological improvements may support use cases, such as wireless fronthauls, wireless midhauls, wireless backhauls, wireless data centers, extended reality (XR) and metaverse applications, meta services for supporting vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage applications using non-terrestrial and / or aerial platforms, among other examples.
[0046] As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases. The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies or new technologies and / or support one or more of the foregoing use cases or new use cases.
[0047] Fig. 1 is a diagram illustrating an example of a wireless communication network 100, in accordance with the present disclosure. The wireless communication network 100 may be or may include elements of a 5G (or NR) network or a 6G network, among other examples. The wireless communication network 100 may include multiple network nodes 110. For example, in Fig. 1, the wireless communication network 100 includes a network node (NN) 110a and a network node 110b. The network nodes 110 may support communications with multiple UEs 120. For example, in Fig. 1, the network nodes 110 support communication with a UE 120a, a UE 120b, and a UE 120c. In some examples, a UE 120 may also communicate with other UEs 120 and a network node 110 may communicate with a core network and with other network nodes 110.
[0048] The network nodes 110 and the UEs 120 of the wireless communication network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, carriers, and / or channels. For example, devices of the wireless communication network 100 may communicate using one or more operating bands. In some aspects, multiple wireless communication networks 100 may be deployed in a given geographic area. Each wireless communication network 100 may support a particular RAT (which may also be referred to as an air interface) and may operate on one or more carrier frequencies in one or more frequency bands or ranges. In some examples, when multiple RATs are deployed in a given geographic area, each RAT in the geographic area may operate on different frequencies to avoid interference with other RATs. Additionally or alternatively, in some examples, the wireless communication network 100 may implement dynamic spectrum sharing (DSS) , in which multiple RATs are implemented with dynamic bandwidth allocation (for example, based on user demand) in a single frequency band. In some examples, the wireless communication network 100 may support communication over unlicensed spectrum, where access to an unlicensed channel is subject to a channel access mechanism. For example, in a shared or unlicensed frequency band, a transmitting device may perform a channel access procedure, such as a listen-before-talk (LBT) procedure, to contend against other devices for channel access before transmitting on a shared or unlicensed channel.
[0049] Various operating bands have been defined as frequency range designations FR1 (410 MHz through 7.125 GHz) , FR2 (24.25 GHz through 52.6 GHz) , FR3 (7.125 GHz through 24.25 GHz) , FR4a or FR4-1 (52.6 GHz through 71 GHz) , FR4 (52.6 GHz through 114.25 GHz) , and FR5 (114.25 GHz through 300 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles, despite being different than the extremely high frequency (EHF) band (30 GHz through 300 GHz) , which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. The frequencies between FR1 and FR2 are often referred to as mid-band frequencies, which include FR3. Frequency bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thus may effectively extend features of FR1 or FR2 into the mid-band frequencies. Thus, “sub-6 GHz, ” if used herein, may broadly refer to frequencies that are less than 6 GHz, that are within FR1, and / or that are included in mid-band frequencies. Similarly, the term “millimeter wave, ” if used herein, may broadly refer to mid-band frequencies or to frequencies that are within FR2, FR4, FR4-a or FR4-1, FR5, and / or the EHF band. Higher frequency bands may extend 5G NR operation, 6G operation, and / or other RATs beyond 52.6 GHz.
[0050] A network node 110 and / or a UE 120 may include one or more devices, components, or systems that enable communication with other devices, components, or systems of the wireless communication network 100. For example, a UE 120 and a network node 110 may each include one or more chips, system-on-chips (SoCs) , chipsets, packages, or devices that individually or collectively constitute or comprise a processing system, such as a processing system 140 of the UE 120 or a processing system 145 of the network node 110. A processing system (for example, the processing system 140 and / or the processing system 145) includes processor (or “processing” ) circuitry in the form of one or multiple processors, microprocessors, processing units (such as central processing units (CPUs) , graphics processing units (GPUs) , neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DLPs) ) , and / or digital signal processors (DSPs) ) , processing blocks, application-specific integrated circuits (ASICs) , programmable logic devices (PLDs) , or other discrete gate or transistor logic or circuitry (any one or more of which may be generally referred to herein individually as a “processor” or collectively as “the processor” or “the processor circuitry” ) . Such processors may be individually or collectively configurable or configured to perform various functions or operations described herein. A group of processors collectively configurable or configured to perform a set of functions may include a first processor configurable or configured to perform a first function of the set and a second processor configurable or configured to perform a second function of the set. In some other examples, each of a group of processors may be configurable or configured to perform a same set of functions.
[0051] The processing system 140 and the processing system 145 may each include memory circuitry in the form of one or multiple memory devices, memory blocks, memory elements, or other discrete gate or transistor logic or circuitry, each of which may include or implement tangible storage media such as random-access memory (RAM) or read-only memory (ROM) , or combinations thereof (any one or more of which may be generally referred to herein individually as a “memory” or collectively as “the memory” or “the memory circuitry” ) . One or more of the memories may be coupled (for example, operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) with one or more of the processors and may individually or collectively store processor-executable code or instructions (such as software) that, when executed by one or more of the processors, may configure one or more of the processors to perform various functions or operations described herein. Additionally or alternatively, in some examples, one or more of the processors may be configured to perform various functions or operations described herein without requiring configuration by software. “Software” shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
[0052] The processing system 140 and the processing system 145 may each include or be coupled with one or more modems (such as a cellular (for example, a 5G or 6G compliant) modem) . In some examples, one or more processors of the processing system 140 and / or the processing system 145 include or implement one or more of the modems. The processing system 140 and the processing system 145 may also include or be coupled with multiple radios (collectively “the radio” ) , multiple RF chains, or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some examples, one or more processors of the processing system 140 and / or the processing system 145 include or implement one or more of the radios, RF chains, or transceivers. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs) , and / or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by the processing system 140 of the UE 120 or by the processing system 145 of the network node 110) .
[0053] A processing system (e.g., the processing system 140 and / or the processing system 145) may generally be a system or a series of machines or components that receives inputs and processes the inputs to produce a set of outputs (which may be passed to other systems or components of, for example, the UE 120) . For example, the processing system 140 of the UE 120 may be a system that includes the various other components or subcomponents of the UE 120. The processing system 140 of the network node 110 may be a system that includes the various other components or subcomponents of the network node 110.
[0054] The processing system 145 of the network node 110 may interface with one or more other components of the network node 110, may process information received from one or more other components (such as inputs or signals) , or may output information to one or more other components. For example, a chip or modem of the network node 110 may include the processing system 145, a first interface to receive or obtain information, and a second interface to output, transmit, or provide information. In some examples, the first interface may be an interface between the processing system 145 of the chip or modem and a receiver, such that the network node 110 may receive information or signal inputs, and the information may be passed to the processing system 145. In some examples, the second interface may be an interface between the processing system 145 of the chip or modem and a transmitter, such that the network node 110 may transmit information output from the chip or modem. Similarly, the processing system 140 of the UE 120 may interface with one or more other components of the UE 120, may process information received from one or more other components (such as inputs or signals) , or may output information to one or more other components. For example, a chip or modem of the UE 120 may include the processing system 140, a first interface to receive or obtain information, and a second interface to output, transmit, or provide information. In some examples, the first interface may be an interface between the processing system 140 of the chip or modem and a receiver, such that the UE 120 may receive information or signal inputs, and the information may be passed to the processing system 140. In some examples, the second interface may be an interface between the processing system 140 of the chip or modem and a transmitter, such that the UE 120 may transmit information output from the chip or modem. A person having ordinary skill in the art will readily recognize that the second interface described above also may obtain or receive information or signal inputs, and the first interface described above may also output, transmit, or provide information.
[0055] A network node 110 and a UE 120 may each include one or multiple antennas or antenna arrays. Typical network nodes 110 and UEs 120 may include multiple antennas, which may be organized or structured into one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. As used herein, the term “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. The term “antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters associated with the group of antennas. The term “antenna module” may refer to circuitry including one or more antennas as well as one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device such as the network node 110 and the UE 120.
[0056] A network node 110 may be, may include, or may also be referred to as an NR network node, a 5G network node, a 6G network node, a Node B, a gNB, an access point (AP) , a transmission reception point (TRP) , a network entity, a network element, a network equipment, and / or another type of device, component, or system included in a radio access network (RAN) . In various deployments, a network node 110 may be implemented as a single physical node (for example, a single physical structure) or may be implemented as two or more physical nodes (for example, two or more distinct physical structures) . For example, a network node 110 may be a device or system that implements a part of a radio protocol stack, a device or system that implements a full radio protocol stack (such as a full gNB protocol stack) , or a collection of devices or systems that collectively implement the full radio protocol stack. For example, and as shown, a network node 110 may be an aggregated network node having an aggregated architecture, meaning that the network node 110 may implement a full radio protocol stack that is physically and logically integrated within a single physical structure in the wireless communication network 100. For example, an aggregated network node 110 may consist of a single standalone base station or a single TRP that operates with a full radio protocol stack to enable or facilitate communication between a UE 120 and a core network of the wireless communication network 100.
[0057] Alternatively, and as also shown, a network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station) , having a disaggregated architecture, meaning that the network node 110 may operate with a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same geographic location or in different geographic locations. An example disaggregated network node architecture is described in more detail below with reference to Fig. 2. In some deployments, disaggregated network nodes 110 may be used in an integrated access and backhaul (IAB) network, in an open radio access network (O-RAN) (such as a network configuration in compliance with the O-RAN Alliance) , or in a virtualized radio access network (vRAN) , also known as a cloud radio access network (C-RAN) , to facilitate scaling by separating network functionality into multiple units or modules that can be individually deployed.
[0058] The network nodes 110 of the wireless communication network 100 may include one or more central units (CUs) , one or more distributed units (DUs) , and one or more radio units (RUs) . A CU may host one or more higher layers, such as an RRC layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, among other examples. A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and / or one or more higher physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some examples, a DU also may host a lower PHY layer that is configured to perform functions, such as a fast Fourier transform (FFT) , an inverse FFT (IFFT) , beamforming, and / or physical random access channel (PRACH) extraction and filtering, among other examples. An RU may perform RF processing functions or lower PHY layer functions, such as an FFT, an IFFT, beamforming, or PRACH extraction and filtering, among other examples, according to a functional split, such as a lower layer split (LLS) . In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 120. In some examples, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. In some examples, a CU, a DU, and / or an RU may be implemented as a virtual unit, such as a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) , among other examples, which may be implemented as a virtual network function, such as in a cloud deployment.
[0059] Some network nodes 110 (for example, a base station, an RU, or a TRP) may provide communication coverage for a particular geographic area. The term “cell” can refer to a coverage area of a network node 110 or to a network node 110 itself, depending on the context in which the term is used. A network node 110 may support one or more cells (for example, each cell may support communication within an angular (for example, 60 degree) range around the network node) . In some examples, a network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs 120 with associated service subscriptions. A pico cell may cover a relatively small geographic area and may also allow unrestricted access by UEs 120 with associated service subscriptions. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs 120 having association with the femto cell (for example, UEs 120 in a closed subscriber group (CSG) ) . In some examples, a cell may not necessarily be stationary. For example, the geographic area of the cell may move according to the location of an associated mobile network node 110 (for example, a train, a satellite, an unmanned aerial vehicle, or an NTN network node) .
[0060] The wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, aggregated network nodes, and / or disaggregated network nodes, among other examples. Various different types of network nodes 110 may generally transmit at different power levels, serve different coverage areas (for example, a cell 130a and a cell 130b) , and / or have different impacts on interference in the wireless communication network 100 than other types of network nodes 110.
[0061] The UEs 120 may be physically dispersed throughout the coverage area of the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or may also be referred to as an access terminal, a mobile station, or a subscriber unit. A UE 120 may be, include, or be coupled with a cellular phone (for example, a smart phone) , a personal digital assistant (PDA) , a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, or smart jewelry) , a gaming device, an entertainment device (for example, a music device, a video device, or a satellite radio) , an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device) , a UE function of a network node, and / or any other suitable device or function that may communicate via a wireless medium.
[0062] Some UEs 120 may be classified according to different categories in association with different complexities and / or different capabilities. UEs 120 in a first category may facilitate massive IoT in the wireless communication network 100, and may offer low complexity and / or cost relative to UEs 120 in a second category. UEs 120 in a second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, and / or premium UEs that are capable of URLLC, eMBB, and / or precise positioning in the wireless communication network 100, among other examples. A third category of UEs 120 may have mid-tier complexity and / or capability (for example, a capability between that of the UEs 120 of the first category and that of the UEs 120 of the second capability) . A UE 120 of the third category may be referred to as a reduced capability UE ( “RedCap UE” ) , a mid-tier UE, an NR-Light UE, and / or an NR-Lite UE, among other examples. RedCap UEs may bridge a gap between the capability and complexity of NB-IoT devices and / or eMTC UEs, and mission-critical IoT devices and / or premium UEs. RedCap UEs may include, for example, wearable devices, IoT devices, industrial sensors, or cameras that are associated with a limited bandwidth, power capacity, and / or transmission range, among other examples. RedCap UEs may support healthcare environments, building automation, electrical distribution, process automation, transport and logistics, or smart city deployments, among other examples.
[0063] In some examples, a network node 110 may be, may include, or may operate as an RU, a TRP, or a base station that communicates with one or more UEs 120 via a radio access link (which may be referred to as a “Uu” link) . The radio access link may include a downlink and an uplink. “Downlink” (or “DL” ) refers to a communication direction from a network node 110 to a UE 120, and “uplink” (or “UL” ) refers to a communication direction from a UE 120 to a network node 110. Downlink and uplink resources may include time domain resources (for example, frames, subframes, slots, and symbols) , frequency domain resources (for example, frequency bands, component carriers (CCs) , subcarriers, resource blocks, and resource elements) , and spatial domain resources (for example, particular transmit directions or beams) .
[0064] Frequency domain resources may be subdivided into bandwidth parts (BWPs) . A BWP may be a block of frequency domain resources (for example, a continuous set of resource blocks (RBs) within a full component carrier bandwidth) that may be configured at a UE-specific level. A UE 120 may be configured with both an uplink BWP and a downlink BWP (which may be the same or different) . Each BWP may be associated with its own numerology (indicating a sub-carrier spacing (SCS) and cyclic prefix (CP) ) . A BWP may be dynamically configured or activated (for example, by a network node 110 transmitting a DCI configuration to the one or more UEs 120) and / or reconfigured (for example, in real-time or near-real-time) according to changing network conditions in the wireless communication network 100 and / or specific requirements of one or more UEs 120. An active BWP defines the operating bandwidth of the UE 120 within the operating bandwidth of the serving cell. The use of BWPs enables more efficient use of the available frequency domain resources in the wireless communication network 100 because fewer frequency domain resources may be allocated to a BWP for a UE 120 (which may reduce the quantity of frequency domain resources that a UE 120 is required to monitor and reduce UE power consumption by enabling the UE to monitor fewer frequency domain resources) , leaving more frequency domain resources to be spread across multiple UEs 120. Thus, BWPs may also assist in the implementation of lower-capability (for example, RedCap) UEs 120 by facilitating the configuration of smaller bandwidths for communication by such UEs 120 and / or by facilitating reduced UE power consumption.
[0065] As used herein, a downlink signal may be or include a reference signal, control information, or data. For example, downlink reference signals include a primary synchronization signal (SS) (PSS) , a secondary SS (SSS) , an SSB (for example, that includes a PSS, an SSS, and a physical broadcast channel (PBCH) ) , a demodulation reference signal (DMRS) , a phase tracking reference signal (PTRS) , a tracking reference signal (TRS) , and a channel state information (CSI) reference signal (CSI-RS) , among other examples. A downlink signal carrying control information or data may be transmitted via a downlink channel. Downlink channels may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Downlink reference signals may be transmitted in addition to, or multiplexed with, downlink control channel communications and / or downlink data channel communications. A downlink control channel may be specifically used to transmit DCI from a network node 110 to a UE 120. DCI generally contains the information the UE 120 needs to identify RBs in a subsequent subframe and how to decode them, including a modulation and coding scheme (MCS) or redundancy version parameters. Different DCI formats carry different information, such as scheduling information in the form of downlink or uplink grants, slot formal indicators (SFIs) , preemption indicators (PIs) , transmit power control (TPC) commands, hybrid automatic repeat request (HARQ) information, new data indicators (NDIs) , among other examples. A downlink data channel may be used to transmit downlink data (for example, user data associated with a UE 120) from a network node 110 to a UE 120. Downlink control channels may include physical downlink control channels (PDCCHs) , and downlink data channels may include physical downlink shared channels (PDSCHs) . Control information or data communications may be transmitted on a PDCCH and PDSCH, respectively. For example, a PDCCH can carry DCI, while a PDSCH can carry a MAC control element (MAC-CE) , an RRC message, or user data, among other examples. Each PDSCH may carry one or more transport blocks (TBs) of data.
[0066] As used herein, an uplink signal may include a reference signal, control information, or data. For example, uplink reference signals include a sounding reference signal (SRS) , a PTRS, and a DMRS, among other examples. An uplink signal carrying control information or data may be transmitted via an uplink channel. An uplink channel may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Uplink reference signals may be transmitted in addition to, or multiplexed with, uplink control channel communications and / or uplink data channel communications. An uplink control channel may be specifically used to transmit uplink control information (UCI) from a UE 120 to a network node 110. An uplink data channel may be used to transmit uplink data (for example, user data associated with a UE 120) from a UE 120 to a network node 110. Uplink control channels may include physical uplink control channels (PUCCHs) , and uplink data channels may include physical uplink shared channels (PUSCHs) . Control information or data communications may be transmitted on a PUCCH and PUSCH, respectively. For example, a PUCCH can carry UCI, while a PUSCH can carry a MAC-CE, an RRC message, or user data, among other examples. UCI can include a scheduling request (SR) , HARQ feedback information (for example, a HARQ acknowledgement (ACK) indication or a HARQ negative acknowledgement (NACK) indication) , uplink power control information (for example, an uplink TPC parameter) , and / or CSI, among other examples. CSI can include a channel quality indicator (CQI) (indicative of downlink channel conditions to facilitate selection of transmission parameters, such as an MCS, by a network node 110) , a precoding matrix indicator (PMI) , a CSI-RS resource indicator (CRI) (for example, indicative of a beam used to transmit a CSI-RS) , an SS / PBCH resource block indicator (SSBRI) (for example, indicative of a beam used to transmit an SSB) , a layer indicator (LI) , a rank indicator (RI) , and / or measurement information (for example, a layer 1 (L1) -reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, among other examples) which can be used for beam management, among other examples. Each PUSCH may carry one or more TBs of data.
[0067] The information (for example, data, control information, or reference signal information) transmitted by a network node 110 to a UE 120, or vice versa, may be represented as a sequence of binary bits that are mapped (for example, modulated) to an analog signal waveform (for example, a discrete Fourier transform (DFT) -spread-orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM) waveform or a CP-OFDM waveform) that is transmitted by the network node 110 or UE 120 over a wireless communication channel. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively) may select an MCS (for example, an order of quadrature amplitude modulation (QAM) , such as 64-QAM, 128-QAM, or 256-QAM, among other examples) for a downlink signal or an uplink signal. For example, the network node 110 may select an MCS for a downlink signal in accordance with UCI received from the UE 120. The network node 110 may transmit, to the UE 120, an indication of the selected MCS for the downlink signal, such as via DCI that schedules the downlink signal. As another example, the network node 110 may transmit, and the UE 120 may receive, an indication of an MCS to be applied for the one or more uplink signals, such as via DCI scheduling transmission of the one or more uplink signals.
[0068] The network node 110 or the UE 120 (such as by using the processing system 145 or the processing system 140, respectively, and / or one or more coupled modems) may perform signal processing on the information (such as filtering, amplification, modulation, digital-to-analog conversion, an IFFT operation, multiplexing, interleaving, mapping, and / or encoding, among other examples) to generate a processed signal in accordance with the selected MCS. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, and / or one or more coupled encoders or modems) may perform a channel coding operation or a forward error correction (FEC) operation to control errors in transmitted information. For example, the network node 110 or the UE 120 may perform an encoding operation to generate encoded information (such as by selectively introducing redundancy into the information, typically using an error correction code (ECC) , such as a polar code or a low-density parity-check (LDPC) code) . The network node 110 or the UE 120 (for example, using the processing system 145 and / or one or more modems) may further perform spatial processing (for example, precoding) on the encoded information to generate one or more processed or precoded signals for downlink or uplink transmission, respectively. In some examples, the network node 110 or the UE 120 may perform codebook-based precoding or non-codebook-based precoding. Codebook-based precoding may involve selecting a precoder (for example, a precoding matrix) using a codebook. For example, the network node 110 may provide precoding information indicating which precoder, defined by the codebook, is to be used by the UE 120. Non-codebook-based precoding may involve selecting or deriving a precoder based on, or otherwise associated with, one or more downlink or uplink signal measurements. The network node 110 or the UE 120 may transmit the processed downlink or uplink signals, respectively, via one or more antennas.
[0069] The network node 110 or the UE 120 may receive uplink signals or downlink signals, respectively, via one or more antennas. The network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, and / or one or more coupled modems) may perform signal processing (for example, in accordance with the MCS) on the received uplink or downlink signals, respectively (such as filtering, amplification, demodulation, analog-to-digital conversion, an FFT operation, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, and / or decoding, among other examples) , to map the received signal (s) to a sequence of binary bits (for example, received information) that estimates the information transmitted by the network node 110 or the UE 120 via the downlink or uplink signals. The network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, and / or a coupled decoder or one or more modems) may decode the received information (such as by using an ECC, a decoding operation, and / or an FEC operation) to detect errors and / or correct bit errors in the received information to generate decoded information. The decoded information may estimate the information transmitted via the downlink or uplink signals.
[0070] In some examples, a UE 120 and a network node 110 may perform MIMO communication. “MIMO” generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. MIMO techniques generally exploit multipath propagation. A network node 110 and / or UE 120 may communicate using massive MIMO, multi-user MIMO, or single-user MIMO, which may involve rapid switching between beams or cells. For example, the amplitudes and / or phases of signals transmitted via antenna elements and / or sub-elements may be modulated and shifted relative to each other (such as by manipulating a phase shift, a phase offset, and / or an amplitude) to generate one or more beams, which is referred to as beamforming. For example, the network node 110b may generate one or more beams 160a, and the UE 120b may generate one or more beams 160b. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction, a directional reception of a wireless signal from a transmitting device or otherwise in a desired direction, a direction associated with a directional transmission or directional reception, a set of directional resources associated with a signal transmission or signal reception (for example, an angle of arrival, a horizontal direction, and / or a vertical direction) , a set of parameters that indicate one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal, among other examples.
[0071] MIMO may be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO may include a massive MIMO technique which may be associated with an increased (for example, “massive” ) quantity of antennas at the network node 110 and / or at the UE 120, such as in a network implementing mmWave technology. Massive MIMO may improve communication reliability by enabling a network node 110 and / or a UE 120 to communicate the same data across different propagation (or spatial) paths. In some examples, MIMO may support simultaneous transmission to multiple receivers, referred to as multi-user MIMO (MU-MIMO) . Some RATs may employ MIMO techniques, such as multi-TRP (mTRP) operation (including redundant transmission or reception on multiple TRPs) , reciprocity in the time domain or the frequency domain, single-frequency-network (SFN) transmission, or non-coherent joint transmission (NC-JT) .
[0072] To support MIMO techniques, the network node 110 and the UE 120 may perform one or more beam management operations, such as an initial beam acquisition operation, one or more beam refinement operations, and / or a beam recovery operation. For example, an initial beam acquisition operation may involve the network node 110 transmitting signals (for example, SSBs, CSI-RSs, or other signals) via respective beams (for example, of the beams 160a of the network node 110) and the UE 120 receiving and measuring the signal (s) via respective beams of multiple beams (for example, from the beams 160b of the UE 120) to identify a best beam (or beam pair) for communication between the UE 120 and the network node 110. For example, the UE 120 may transmit an indication (for example, in a message associated with a random access channel (RACH) operation) of a (best) identified beam of the network node 110 (for example, by indicating an SSBRI or other identifier associated with the beam) . A beam refinement operation may involve a first device (for example, the UE 120 or the network node 110) transmitting signal (s) via a subset of beams (for example, identified based on, or otherwise associated with, measurements reported as part of one or more other beam management operations) . A second device (for example, the network node 110 or the UE 120) may receive the signal (s) via a single beam (for example, to identify the best beam for communication from the subset of beams) . The beam (s) may be identified via one or more spatial parameters, such as a transmission configuration indicator (TCI) state and / or a quasi co-location (QCL) parameter, among other examples. The network node 110 and the UE 120 may increase reliability and / or achieve efficiencies in throughput, signal strength, and / or other signal properties for massive MIMO operations by performing the beam management operations.
[0073] Some aspects and techniques as described herein may be implemented, at least in part, using an artificial intelligence (AI) program (for example, referred to herein as an “AI / ML model” ) , such as a program that includes a machine learning (ML) model and / or an artificial neural network (ANN) model. The AI / ML model may be deployed at one or more devices 165 (for example, a network node 110 and / or UEs 120) . For example, the one or more devices 165 may include a UE 120 (for example, the processing system 140) , a network node 110 (for example, the processing system 145) , one or more servers, and / or one or more components of a cloud computing network, among other examples. In some examples, the AI / ML model (or an instance of the AI / ML model) may be deployed at multiple devices (for example, a first portion of the AI / ML model may be deployed at a UE 120 and a second portion of the AI / ML model may be deployed at a network node 110) . In other examples, a first AI / ML model may be deployed at a UE 120 and a second AI / ML model may be deployed at a network node 110. The AI / ML model (s) may be configured to enhance various aspects of the wireless communication network 100. For example, the AI / ML model (s) may be trained to identify patterns or relationships in data corresponding to the wireless communication network 100, a device, and / or an air interface, among other examples. The AI / ML model (s) may support operational decisions relating to one or more aspects associated with wireless communications devices, networks, or services.
[0074] In some aspects, the UE 120 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may switch from a first PDCCH monitoring mode to a second PDCCH monitoring mode in accordance with a switching condition; and transmit , to a network node, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0075] In some aspects, the network node 110 may include a communication manager 155. As described in more detail elsewhere herein, the communication manager 155 may transmit, to a UE, configuration information associated with at least one of a first PDCCH monitoring mode or a second PDCCH monitoring mode; and receive, from the UE and in accordance with a switching condition, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode. Additionally, or alternatively, the communication manager 155 may perform one or more other operations described herein.
[0076] Fig. 2 is a diagram illustrating an example disaggregated network node architecture 200, in accordance with the present disclosure. One or more components of the example disaggregated network node architecture 200 may be, may include, or may be included in one or more network nodes (such one or more network nodes 110) . The disaggregated network node architecture 200 may include a CU 210 that can communicate directly with a core network 220 via a backhaul link, or that can communicate indirectly with the core network 220 via one or more disaggregated control units, such as a non-real-time (Non-RT) RAN intelligent controller (RIC) 250 associated with a Service Management and Orchestration (SMO) Framework 260 and / or a near-real-time (Near-RT) RIC 270 (for example, via an E2 link) . The CU 210 may communicate with one or more DUs 230 via respective midhaul links, such as via F1 interfaces. Each of the DUs 230 may communicate with one or more RUs 240 via respective fronthaul links. Each of the RUs 240 may communicate with one or more UEs 120 via respective RF access links. In some deployments, a UE 120 may be simultaneously served by multiple RUs 240.
[0077] Each of the components of the disaggregated network node architecture 200, including the CUs 210, the DUs 230, the RUs 240, the Near-RT RICs 270, the Non-RT RICs 250, and the SMO Framework 260, may include one or more interfaces or may be coupled with one or more interfaces for receiving or transmitting signals, such as data or information, via a wired or wireless transmission medium.
[0078] In some aspects, the CU 210 may be logically split into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 210 may be deployed to communicate with one or more DUs 230, as necessary, for network control and signaling. Each DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. For example, a DU 230 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules) hosted by the DU 230, or for communicating signals with the control functions hosted by the CU 210. Each RU 240 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU (s) 240 may be controlled by the corresponding DU 230.
[0079] The SMO Framework 260 may support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 260 may support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface, such as an O1 interface. For virtualized network elements, the SMO Framework 260 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface, such as an O2 interface. A virtualized network element may include, but is not limited to, a CU 210, a DU 230, an RU 240, a non-RT RIC 250, and / or a Near-RT RIC 270. In some aspects, the SMO Framework 260 may communicate with a hardware aspect of a 4G RAN, a 5G NR RAN, and / or a 6G RAN, such as an open eNB (O-eNB) 280, via an O1 interface. Additionally or alternatively, the SMO Framework 260 may communicate directly with each of one or more RUs 240 via a respective O1 interface. In some deployments, this configuration can enable each DU 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0080] The Non-RT RIC 250 may include or may implement a logical function that enables non-real-time control and optimization of RAN elements and resources, AI / ML workflows including model training and updates, and / or policy-based guidance of applications and / or features in the Near-RT RIC 270. The Non-RT RIC 250 may be coupled to or may communicate with (such as via an A1 interface) the Near-RT RIC 270. The Near-RT RIC 270 may include or may implement a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions via an interface (such as via an E2 interface) connecting one or more CUs 210, one or more DUs 230, and / or an O-eNB 280 with the Near-RT RIC 270.
[0081] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 270, the Non-RT RIC 250 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 270 and may be received at the SMO Framework 260 or the Non-RT RIC 250 from non-network data sources or from network functions. In some examples, the Non-RT RIC 250 or the Near-RT RIC 270 may tune RAN behavior or performance. For example, the Non-RT RIC 250 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the SMO Framework 260 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .
[0082] The network node 110, the processing system 145 of the network node 110, the UE 120, the processing system 140 of the UE 120, the CU 210, the DU 230, the RU 240, or any other component (s) of Fig. 1 and / or Fig. 2 may implement one or more techniques or perform one or more operations associated with switching between PDCCH monitoring modes, as described in more detail elsewhere herein. For example, the processing system 145 of the network node 110, the processing system 140 of the UE 120, the CU 210, the DU 230, or the RU 240 may perform or direct operations of, for example, process 300 of Fig. 3, process 400 of Fig. 4, or other processes as described herein (alone or in conjunction with one or more other processors) . Memory of the network node 110 may store data and program code (or instructions) for the network node 110, the CU 210, the DU 230, or the RU 240. In some examples, the memory of the network node 110 may store data relating to a UE 120, such as RRC state information or a UE context. Memory of a UE 120 may store data and program code (or instructions) for the UE 120, such as context information. In some examples, the memory of the UE 120 or the memory of the network node 110 may include a non-transitory computer-readable medium storing a set of instructions for wireless communication. For example, the set of instructions, when executed by one or more processors (for example, of the processing system 145 or the processing system 140) of the network node 110, the UE 120, the CU 210, the DU 230, or the RU 240, may cause the one or more processors to perform process 300 of Fig. 3, process 400 of Fig. 4, or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.
[0083] In some aspects, the UE 120 includes means for switching from a first PDCCH monitoring mode to a second PDCCH monitoring mode in accordance with a switching condition; and / or means for transmitting, to a network node, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode. The means for the UE 120 to perform operations described herein may include, for example, one or more of communication manager 150, processing system 140, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 502 depicted and described in connection with Fig. 5) , and / or a transmission component (for example, transmission component 504 depicted and described in connection with Fig. 5) , among other examples.
[0084] In some aspects, the network node 110 includes means for transmitting, to a UE, configuration information associated with at least one of a first PDCCH monitoring mode or a second PDCCH monitoring mode; and / or means for receiving, from the UE and in accordance with a switching condition, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode. The means for the network node to perform operations described herein may include, for example, one or more of communication manager 155, processing system 145, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 602 depicted and described in connection with Fig. 6) , and / or a transmission component (for example, transmission component 604 depicted and described in connection with Fig. 6) , among other examples.
[0085] Various aspects of the present disclosure are described with reference to the following examples.
[0086] Example 1: Switching from LP-WUS-based PDCCH monitoring Option 1 to non-LP-WUS-based PDCCH monitoring.
[0087] In Example 1, DCP may not be configured to a UE. When the UE detects that the UE moves outside of LP-WUS coverage or the UE is leaving the LP-WUS-based PDCCH monitoring mode, the UE may transmit, to a network node (e.g., a gNB) , an indication associated with switching from the LP-WUS-based PDCCH monitoring mode to a non-LP-WUS-based PDCCH monitoring mode. For example, the UE may transmit the indication via RRC signaling or a MAC-CE. The UE may transmit, to the network node, an indication with at least one of the following information: the UE has switched to non-LP-WUS-based PDCCH monitoring, the UE will switch to non-LP-WUS-based PDCCH monitoring, one or more link quality measurement results, a recommended LP-WUS configuration and / or recommended LP-WUS parameters associated with an LP-WUS that UE can still receive with the current link quality (if any) (e.g., in this case, the UE may switch to another LP-WUS-based PDCCH monitoring mode associated with another LP-WUS configuration) , or indication that a switching condition is satisfied. The UE may transmit the indication to the network node when one of the following conditions is satisfied: a measurement result is below a threshold (e.g., if configured) ; the UE cannot detect LP-WUS signal; the UE already switched to the non-LP-WUS-based PDCCH monitoring mode; or the UE will switch to the non-LP-WUS-based PDCCH monitoring mode. The UE may be configured (e.g., via configuration information transmitted by the network node and received by the UE) when to transmit the indication to the network node. The configuration information may indicate: the measurement threshold (e.g., the threshold to be compared to the link quality measurement result) ; that the UE is to transmit the indication when the UE cannot detect the LP-WUS signal; that the UE is to transmit the indication when the UE has already switched to the non-LP-WUS-based PDCCH monitoring mode; or that the UE is to transmit the indication when the UE determines that the UE will switch to the non-LP-WUS-based PDCCH monitoring mode. In Example 1, the UE may autonomously switch to the non-LP-WUS-based PDCCH monitoring mode (without DCP configured) , or the UE may switch the non-LP-WUS-based PDCCH monitoring mode in connection with receiving a switching command from the network node.
[0088] Example 2: Switching from LP-WUS-based PDCCH monitoring Option 1 to non-LP-WUS-based PDCCH monitoring with DCP configured, and / or switching from LP-WUS-based monitoring Option 2 to non-LP-WUS-based PDCCH monitoring with or without DCP configured.
[0089] In Example 2, the UE may switch from LP-WUS-based PDCCH monitoring Option 1 to non-LP-WUS-based PDCCH monitoring with DCP configured, or the UE may switch from LP-WUS-based PDCCH monitoring Option 2 to non-LP-WUS-based PDCCH monitoring with or without DCP configured. When the UE detects that the UE moves outside of LP-WUS coverage or the UE is leaving the LP-WUS-based PDCCH monitoring mode, the UE may transmit, to a network node (e.g., a gNB) , an indication associated with switching from the LP-WUS-based PDCCH monitoring mode to a non-LP-WUS-based PDCCH monitoring mode. For example, the UE may transmit the indication via RRC signaling or a MAC-CE. The UE may transmit, to the network node, an indication with at least one of the following information: the UE will switch to non-LP-WUS-based PDCCH monitoring, one or more link quality measurement results, a recommended LP-WUS configuration and / or recommended LP-WUS parameters associated with an LP-WUS that UE can still receive with the current link quality (if any) (e.g., in this case, the UE may switch to another LP-WUS-based PDCCH monitoring mode associated with another LP-WUS configuration) , or indication that a switching condition is satisfied. The UE may transmit the indication to the network node when one of the following conditions is satisfied: a measurement result is below a threshold (e.g., if configured) ; the UE cannot detect LP-WUS signal; or the UE will switch to the non-LP-WUS-based PDCCH monitoring mode. The UE may be configured (e.g., via configuration information transmitted by the network node and received by the UE) when to transmit the indication to the network node. The configuration information may indicate: the measurement threshold (e.g., the threshold to be compared to the link quality measurement result) ; that the UE is to transmit the indication when the UE cannot detect the LP-WUS signal; or that the UE is to transmit the indication when the UE determines that the UE will switch to the non-LP-WUS-based PDCCH monitoring mode. The network node may transmit a switching command to the UE, and the UE may switch to the non-LP-WUS-based PDCCH monitoring mode in connection with receiving the switching command. For example, the network node may transmit the switching command via a MAC-CE, RRC signaling, or physical layer signaling (e.g., DCI) .
[0090] Example 3: Switching from non-LP-WUS-based PDCCH monitoring with or without DCP to LP-WUS-based PDCCH monitoring (e.g., Option 1 or Option 2) .
[0091] In Example 3, when the UE detects that the UE moves inside of LP-WUS coverage or enters the LP-WUS-based PDCCH monitoring mode, the UE may transmit, to a network node (e.g., a gNB) , an indication associated with switching from the non-LP-WUS-based PDCCH monitoring mode to an LP-WUS-based PDCCH monitoring mode. For example, the UE may transmit the indication via RRC signaling or a MAC-CE. The UE may transmit, to the network node, an indication with at least one of the following information: the UE will switch to the LP-WUS-based PDCCH monitoring mode, one or more link quality measurement results, or indication that a switching condition is satisfied. The UE may transmit the indication to the network node when one of the following conditions is satisfied: a measurement result is above a threshold (e.g., if configured) ; the UE can detect an LP-WUS signal; or the UE will switch to the LP-WUS-based PDCCH monitoring mode. The UE may be configured (e.g., via configuration information transmitted by the network node and received by the UE) when to transmit the indication to the network node. The configuration information may indicate: the measurement threshold (e.g., the threshold to be compared to the link quality measurement result) ; that the UE is to transmit the indication when the UE can detect the LP-WUS signal; or that the UE is to transmit the indication when the UE determines that the UE will switch to the LP-WUS-based PDCCH monitoring mode. The network node may transmit a switching command to the UE, and the UE may switch to the LP-WUS-based PDCCH monitoring mode in connection with receiving the switching command. For example, the network node may transmit the switching command via a MAC-CE, RRC signaling, or physical layer signaling (e.g., DCI) . The switching command may indicate which LP-WUS configuration (e.g., from one or more LP-WUS configurations configured for the UE) is activated for the LP-WUS-based PDCCH monitoring mode.
[0092] Fig. 3 is a diagram illustrating an example process 300 performed, for example, at a UE or an apparatus of a UE, in accordance with the present disclosure. Example process 300 is an example where the apparatus or the UE (e.g., UE 120) performs operations associated with switching between PDCCH monitoring modes.
[0093] As shown in Fig. 3, in some aspects, process 300 may include switching from a first PDCCH monitoring mode to a second PDCCH monitoring mode in accordance with a switching condition (block 310) . For example, the UE (e.g., using communication manager 506, depicted in Fig. 5) may switch from a first PDCCH monitoring mode to a second PDCCH monitoring mode in accordance with a switching condition, as described above.
[0094] As further shown in Fig. 3, in some aspects, process 300 may include transmitting, to a network node, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode (block 320) . For example, the UE (e.g., using transmission component 504 and / or communication manager 506, depicted in Fig. 5) may transmit, to a network node, an indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode, as described above.
[0095] Process 300 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.
[0096] In a first aspect, process 300 includes receiving, from a network node, configuration information associated with the first PDCCH monitoring mode and the second PDCCH monitoring mode.
[0097] In a second aspect, alone or in combination with the first aspect, the configuration information indicates the switching condition.
[0098] In a third aspect, alone or in combination with one or more of the first and second aspects, process 300 includes receiving, from the network node, a switching command indicating for the UE to switch from the first PDCCH monitoring mode to the second PDCCH monitoring mode, wherein switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode includes switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode in connection with receiving the switching command.
[0099] In a fourth aspect, alone or in combination with one or more of the first through third aspects, the switching command is received via RRC signaling, a MAC-CE, or DCI.
[0100] In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, the indication associated with switching from the first PDCCH monitoring mode to the second PDCCH monitoring mode is transmitted via RRC signaling or a MAC-CE.
[0101] In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the first PDCCH monitoring mode is an LP-WUS-based PDCCH monitoring mode, and the second PDCCH monitoring mode is a non-LP-WUS-based PDCCH monitoring mode.
[0102] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the switching condition is associated with the UE moving outside of an LP-WUS coverage area or leaving the LP-WUS-based PDCCH monitoring mode.
[0103] In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, the switching condition includes at least one of a link quality measurement result being below a threshold, or the UE being unable to detect an LP-WUS associated with the LP-WUS-based PDCCH monitoring mode.
[0104] In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, the LP-WUS-based PDCCH monitoring mode is associated with LP-WUS triggered PDCCH monitoring in PDCCH occasions in an active time of a DRX cycle, and the non-LP-WUS-based PDCCH monitoring mode is configured without DCP.
