Technical Field

[0001] Cross-reference This patent application claims the benefit of U.S. Patent Application No. 18,061,347, filed Dec. 02, 2022, by Lei et al. entitled "DOWNLINK CONTROL CHANNEL MONITORING IN MULTIPLE DOWNLINK BANDWIDTH PARTS", which claims priority to U.S. Provisional Patent Application No. 63 / 297,691, filed Jan. 07, 2022, by Lei et al. entitled "DOWNLINK CONTROL CHANNEL MONITORING IN MULTIPLE DOWNLINK BANDWIDTH PARTS", each of which is assigned to the assignee of this application and incorporated herein by reference in its entirety.

[0002] The following relates to wireless communication including downlink control channel monitoring in multiple downlink bandwidth parts (BWPs).

Background Art

[0003] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems may enable communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi-connection systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems sometimes referred to as New Radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multi-connection communication system may include one or more base stations or one or more network access nodes that each simultaneously support communication for a plurality of communication devices, sometimes known as user equipment (UE). Components within a wireless communication system may be coupled (e.g., operably, communicatively, functionally, electronically, and / or electrically) to each other.

[0004] An idle or non-active UE may be configured to monitor resources in different bandwidth parts (BWPs). For example, an idle or non-active UE may switch from a first downlink BWP to a second downlink BWP so that the UE can monitor downlink transmissions in the second downlink BWP. However, in some cases, switching between downlink BWPs and monitoring a relatively large number of resources may result in higher power consumption and higher processing overhead in the UE. SUMMARY OF THE INVENTION

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support downlink control channel monitoring in multiple downlink bandwidth parts (BWPs). Generally, the techniques described provide for improving the efficiency of downlink monitoring procedures in an idle or non-active user equipment (UE). The UE may receive from a network entity one or more control messages indicating a configuration for a first downlink BWP associated with a first operating mode of the UE, a second downlink BWP associated with a second operating mode of the UE, a first set of resources within the first downlink BWP, and a second set of resources within the second downlink BWP. At least a portion of the configuration may correspond to the capabilities of the UE. The UE may monitor the first set of resources while in the first operating mode and may monitor the second set of resources while in the second operating mode. The UE may receive a system information update or a public warning system (PWS) notification from the network entity via the second set of resources. The techniques described herein may enable a UE (e.g., an idle or non-active UE) to perform downlink channel monitoring with, among other benefits, reduced power consumption and greater processing efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0104] Compared to other user equipment (UEs), a reduced-capability (RedCap) UE may be associated with reduced processing power, longer battery life, and lower overall cost. Thus, RedCap UEs may be suitable for, among other examples, Internet of Things (IoT), augmented reality (AR), virtual reality (VR), and vehicle-to-everything (V2X) applications. In some cases, a RedCap UE in an idle mode or an inactive mode may be configured to monitor a first downlink bandwidth part (BWP) for system information updates, paging messages (e.g., messages for paging operations), or cell definition (CD) synchronization signal blocks (SSBs) from a network entity. The RedCap UE may also be configured using a second initial downlink BWP that may be unique to the RedCap UE. The RedCap UE may be able to monitor a second downlink BWP for random access messages, paging messages, or non-cell definition (NCD) SSBs from a network entity.

[0105] However, when the first downlink BWP and the second downlink BWP correspond to different frequency bands, monitoring both the first downlink BWP and the second downlink BWP can result in higher power consumption and reduced processing efficiency in the RedCap UE. For example, the RedCap UE can perform a relatively large number of blind decoding operations (e.g., monitoring the downlink channel for notification and scheduling information) even when it is not scheduled to receive downlink transmissions from the network entity on the resources within the first downlink BWP and the resources within the second downlink BWP.

[0106] To reduce the processing cost and power consumption associated with the downlink monitoring procedure for an idle or inactive RedCap UE, the total number of control resources within the first downlink BWP and the second downlink BWP (e.g., the downlink BWP configured for the RedCap UE) can be restricted by the threshold number of control resource sets (CORESETs) and the threshold number of search spaces (SSs). For example, the network entity can configure the first downlink BWP and the second downlink BWP such that the total number of CORESETs and SSs within the first downlink BWP and the second downlink BWP is less than the threshold. In some examples, the total number of CORESETs and SSs within the first downlink BWP and the second downlink BWP can depend on the capabilities of non-RedCap UEs.

[0107] A network entity (e.g., a base station) can configure a RedCap UE using a first downlink BWP and a second downlink BWP via system information or radio resource control (RRC) signaling. After the network entity configures the RedCap UE with the first downlink BWP and the second downlink BWP, the RedCap UE can monitor both the first downlink BWP and the second downlink BWP according to the information provided by the network entity. In some examples, the network entity can send a system information update or a public warning system (PWS) notification to the RedCap UE via resources within the second downlink BWP.

[0108] Aspects of the present disclosure may be implemented to realize one or more of the following advantages. The techniques described can support, among other benefits, greater processing efficiency and reduced power consumption in a RedCap UE. For example, the techniques described herein can reduce the number of control resources (e.g., CORESETs, SSs) configured to be monitored while the RedCap UE is operating in an idle or inactive mode, which can reduce the processing cost and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by the RedCap UE. Specifically, the techniques described can reduce the number of blind decoding operations performed by the RedCap UE, which can enable the RedCap UE to perform idle or inactive mode operations with higher processing efficiency (e.g., using fewer processing resources) and reduced power consumption.

[0109] Aspects of the present disclosure are first described in the context of a wireless communication system, resource diagrams, and process flows. Aspects of the present disclosure are further illustrated by, and described with reference to, apparatus diagrams, system diagrams, and flowcharts related to downlink control channel monitoring in multiple downlink BWPs.

[0110] FIG. 1 shows an example of a wireless communication system 100 that supports downlink control channel monitoring in a plurality of downlink BWPs according to an aspect of the present disclosure. The wireless communication system 100 may include one or more base stations 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 LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support extended broadband communication, ultra-reliable communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0111] The base stations 105 may be distributed across the geographical area to form the wireless communication system 100 and may be different forms of devices or devices with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 where the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographical area where the base stations 105 and the UEs 115 may support signal communication according to one or more radio access technologies.

[0112] UE 115 may be distributed throughout the wireless communication system 100, and each UE 115 may be fixed or mobile. UE 115 may also be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or by some other suitable term, and the "device" may also be referred to as a unit, station, terminal, or client. UE 115 may be a cellular phone, smartphone, personal digital assistant (PDA), multimedia / entertainment device (e.g., radio, MP3 player, video device), camera, game console, navigation / positioning device (e.g., GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), Beidou, GLONASS, or Galileo, ground-based device), tablet computer, laptop computer, netbook, smartbook, personal computer, smart device, wearable device (e.g., smartwatch, smart clothing, smart glasses, virtual reality goggles, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), drone, robot / robot device, vehicle, vehicle device, meter (e.g., parking meter, electric meter, gas meter, water meter), monitor, gas pump, household appliance (e.g., kitchen appliance, washing machine, dryer), location tag, medical / healthcare device, implant, sensor / actuator, device such as a display, or any other suitable device configured to communicate via a wireless or wired medium. In some examples, UE 115 may also refer to a wireless local loop (WLL) station, Internet of Things (IoT) device, any Internet of Everything (IoE) device, or machine type communication (MTC) device, which may be implemented in various articles such as appliances, drones, robots, vehicles, or meters.

[0113] In some examples, one or more components of the wireless communication system 100 may operate as a network node or may be referred to as a network node. As used herein, a network node may refer to any UE 115, base station 105, entity of the core network 130, device, apparatus, or computing system configured to perform any of the techniques described herein. For example, the network node may be a UE 115. As another example, the network node may be a base station 105. As another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE 115, the second network node may be a base station 105, and the third network node may be a UE 115. In another aspect of this example, the first network node may be a UE 115, the second network node may be a base station 105, and the third network node may be a base station 105. In yet another aspect of this example, the first network node, the second network node, and the third network node may be different. Similarly, references to UE 115, base station 105, device, apparatus, or computing system may include the disclosure of a UE 115, base station 105, device, apparatus, or computing system that is a network node. For example, the disclosure that a UE 115 is configured to receive information from a base station 105 also discloses that a first network node is configured to receive information from a second network node. In this example, consistent with the present disclosure, the first network node may refer to a first UE 115, a first base station 105, a first device, a first apparatus, or a first computing system configured to receive information, and the second network node may refer to a second UE 115, a second base station 105, a second device, a second apparatus, or a second computing system.

[0114] The base station 105 can communicate with the core network 130, or can communicate with other base stations 105, or can perform both communications. For example, the base station 105 can interface with the core network 130 through one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base station 105 can communicate with each other either directly (e.g., directly between base stations 105) or indirectly (e.g., via the core network 130), or both, via the backhaul link 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul link 120 may be one or more wireless links, or may include one or more wireless links.

[0115] One or more of the base stations 105 described herein may include a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (any of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terms, or may be so called by those skilled in the art.

[0116] UE115 may include, or be referred to as, a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, and may be referred to as a "device" which, among other examples, may also be called a unit, station, terminal, or client. UE115 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, UE115 may be implemented in various articles such as appliances, or various articles such as vehicles, meters, etc., and may include, among other examples, a wireless local loop (WLL) station, an Internet of Things (IoT) device, any Internet of Everything (IoE) device, or a machine type communications (MTC) device, or be referred to as such.

[0117] As shown in FIG. 1, the UE115 described herein may be able to communicate with various types of devices such as other UE115s that may act as relays, and base stations 105 and network equipment including, among other examples, macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0118] UE 115 and base station 105 may communicate wirelessly with each other via one or more communication links 125 over one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, the carrier used for communication link 125 may include a portion of a radio frequency spectrum band (e.g., BWP) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate the operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 may be composed of a plurality of downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used for both frequency division duplexing (FDD) component carriers and time division duplexing (TDD) component carriers.

[0119] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have collection signaling or control signaling that coordinates its operation with other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be arranged according to a channel raster for discovery by UE115. A carrier may operate in a stand-alone mode where initial collection and connection can be performed by UE115 via the carrier, or the carrier may operate in a non-stand-alone mode where the connection is anchored using different carriers (e.g., of the same or different radio access technologies).

[0120] The communication link 125 shown within the wireless communication system 100 may include an uplink transmission from UE115 to the base station 105, or a downlink transmission from the base station 105 to UE115. A carrier may carry downlink communication or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink communication and uplink communication (e.g., in TDD mode).

[0121] A carrier may be associated with a particular bandwidth of the radio frequency spectrum. In some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., the base station 105, the UE 115, or both) may have a hardware configuration that supports communication via a particular carrier bandwidth or may be configurable to support communication via one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate across a portion (e.g., a sub-band, a BWP) or all of the carrier bandwidth.

[0122] The signal waveform transmitted on a carrier can be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system adopting an MCM technique, a resource element may consist of one symbol period (e.g., the duration of one modulated symbol) and one subcarrier, where the symbol period and the subcarrier spacing are 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 coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE115 receives and the higher the order of the modulation scheme, the higher the data rate can be for the UE115. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further enhance the data rate or data integrity for communication with the UE115.

[0123] One or more numerologies for a carrier may be supported, and the numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs having the same or different numerologies. In some examples, the UE115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communication for the UE115 may be restricted to one or more active BWPs.

[0124] The time interval for the base station 105 or the UE115 is, for example, T s =1 / (Δf max ·N f) can be expressed as a multiple of a basic time unit that can refer to a sampling period of seconds, where Δf max can represent the maximum supported subcarrier spacing, and N f can represent the maximum supported discrete Fourier transform (DFT) size. The time intervals of the communication resources can be organized according to radio frames each having 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).

[0125] Each frame may include a plurality of consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into several slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include several symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communication systems, a slot may be further divided into a plurality of minislots each including one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f number of) sampling periods. The duration of the symbol period may depend on the subcarrier spacing or the frequency band of operation.

[0126] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods within a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., within a burst of shortened TTIs (sTTIs)).

[0127] Physical channels may be multiplexed on a carrier according to various techniques. The physical control channel and the physical data channel may be multiplexed on a downlink carrier using, for example, one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., CORESET) for the physical control channel may be defined by the number of symbol periods and may span the carrier's system bandwidth or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may be able to monitor or search for a control region for control information according to one or more SS sets, where each SS set may include one or more control channel candidates within one or more aggregation levels (ALs) arranged in a cascaded manner. An AL for a control channel candidate may refer to several control channel resources (e.g., control channel elements (CCEs)) associated with the encoded information for a control information format having a given payload size. An SS set may include a common search space set (CSS) configured to send control information to a plurality of UEs 115 and a UE-specific SS set for sending control information to a specific UE 115 and USS.

[0128] Each base station 105 may provide communication coverage via one or more cells, such as macro cells, small cells, hotspots, or other types of cells, or any combination thereof. The term "cell" may refer to a logical communication entity used for communication with the base station 105 (e.g., on a carrier), and may be associated with an identifier (e.g., physical cell identifier (PCID), virtual cell identifier (VCID), or others) for distinguishing neighboring cells. In some examples, a cell may also refer to a geographical coverage area 110 in which the logical communication entity operates or a portion (e.g., a sector) of the geographical coverage area 110. Such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas depending on various factors such as the capabilities of the base station 105. For example, a cell may be, among other things, a building, a subset of a building, or an external space between or overlapping with the geographical coverage area 110, or may include them.

[0129] A macro cell generally covers a relatively large geographical area (e.g., several kilometers in radius) and may enable unrestricted access by UEs 115 subscribed to the services of the network provider supporting the macro cell. A small cell may be associated with a base station 105 of lower power compared to a macro cell, and the small cell may operate in the same or a different (e.g., licensed, unlicensed) frequency band as the macro cell. The small cell may provide unrestricted access to UEs 115 subscribed to the services of the network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 within a closed subscriber group (CSG), UEs 115 associated with users within a home or office). The base station 105 may support one or more cells, or may support communication on one or more cells using one or more component carriers.

[0130] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0131] In some examples, base station 105 may be mobile and thus may provide communication coverage to a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include a heterogeneous network, for example, where different types of base stations 105 provide coverage to various geographic coverage areas 110 using the same or different radio access technologies.

[0132] Some UEs 115, such as MTC devices or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that enable devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC involves incorporating sensors or meters to measure or capture information and relaying that information to a central server or application program that can utilize the information, or presenting the information to a human who can interact with the program or application. Some UEs 115 may be designed to collect information or enable automated behavior of machines. Examples of MTC device applications include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security detection, physical access control, and transaction-based business billing. In one aspect, the techniques disclosed herein may be applicable to MTC UEs or IoT UEs 115. MTC UEs or IoT UEs 115 may include MTC / extended MTC (also referred to as category (CAT)-M, CAT M1) UEs, NB-IoT (also referred to as CAT NB1) UEs 115, and other types of UEs 115. eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further extended eMTC), and mMTC (massive MTC), and NB-IoT may include eNB-IoT (extended NB-IoT), and FeNB-IoT (further extended NB-IoT).

[0133] Some UEs 115 may be configured to adopt an operation mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but does not support simultaneous transmission and reception). In some examples, the half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for the UE 115 may include entering a power saving deep sleep mode when not participating in active communication, operating over a limited bandwidth (e.g., in accordance with narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks) within a carrier, within a guard band of the carrier, or outside the carrier.

[0134] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 may be designed to support ultra-reliability, low latency, or critical functions. Ultra-reliable communication may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, data, etc. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial use. The terms ultra-reliable, low latency, and ultra-reliable low latency may be used interchangeably herein.

[0135] In some examples, UE 115 may also be able to communicate directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) protocol or a D2D protocol). One or more UEs 115 that utilize D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or, in some cases, may not be able to receive transmissions from the base station 105. In some examples, a group of UEs 115 that communicate via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to all other UEs 115 within the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without the involvement of the base station 105.

[0136] In some systems, the D2D communication link may be an example of a communication channel such as a sidelink communication channel between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. Vehicles may signal traffic conditions, signal scheduling, weather, safety, information related to emergencies, or any other information related to the V2X system. In some examples, vehicles within the V2X system may communicate with roadside infrastructure such as roadside units and / or with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication or both.

[0137] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access functions, routing functions, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the evolved packet core (EPC) or 5G core (5GC) may include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)), and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UE 115 served by the base station 105 associated with the core network 130. User IP packets may be transferred through a user plane entity that may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for one or more network operators. The IP service 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or a packet-switched streaming service.

[0138] Some of the network devices such as base station 105 may include subcomponents such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transmission entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or integrated into a single network device (e.g., base station 105).

[0139] Wireless communication system 100 may typically operate using one or more frequency bands in the range from 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or the decimeter band since the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by building and environmental characteristics, but the waves can penetrate structures well enough for a macrocell to provide service to a UE 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmission using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0140] The wireless communication system 100 can also operate in the super high frequency (SHF) region that uses a frequency band from 3 GHz to 30 GHz, also known as the centimeter band, or in the extremely high frequency (EHF) region of the spectrum, also known as the millimeter band (e.g., from 30 GHz to 300 GHz). In some examples, the wireless communication system 100 can support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of each device can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions can experience even greater atmospheric attenuation than SHF or UHF transmissions and may have shorter distances. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of bands across these frequency regions may vary by country or regulatory body.

[0141] The wireless communication system 100 can utilize both the authorized radio frequency spectrum band and the unlicensed radio frequency spectrum band. For example, the wireless communication system 100 can utilize License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in the unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 can utilize carrier sensing for collision detection and avoidance. In some examples, operation in the unlicensed band may be based on a carrier aggregation configuration in cooperation with a component carrier operating in an authorized band (e.g., LAA). Operation in the unlicensed spectrum can include, among other examples, downlink transmission, uplink transmission, P2P transmission, or D2D transmission.

[0142] The base station 105 or the UE 115 may be equipped with multiple antennas that can be used to utilize techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the base station 105 or the UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be placed together in an antenna assembly such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at various geographical locations. The base station 105 may have an antenna array having several rows and columns of antenna ports that can be used to support beamforming for communication with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO operations or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0143] The base station 105 or the UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving a plurality of signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The plurality of signals may be transmitted by a transmitting device via, for example, different antennas or different combinations of antennas. Similarly, the plurality of signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the plurality of signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). The different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which a plurality of spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) in which a plurality of spatial layers are transmitted to a plurality of devices.

[0144] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used in a transmitting device or a receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated through the antenna elements of an antenna array such that some signals propagating in a particular direction with respect to the antenna array experience constructive interference while other signals experience destructive interference. Adjustment of the signals communicated through the antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both, to the signals carried through the antenna elements associated with the device. The adjustment associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other direction).

[0145] The wireless communication system 100 can be a packet-based network that operates according to a hierarchical protocol stack. In the user plane, the communication in the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly to communicate on the logical channel. The Media Access Control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmission in the MAC layer and improve link efficiency. In the control plane, the RRC protocol layer can establish, configure, and maintain the RRC connection between the UE 115 and the base station 105 or the core network 130, which supports the radio bearer for the user plane data. In the physical layer, the transport channel can be mapped to the physical channel.

[0146] UE115 and base station 105 may support retransmission of data to increase the likelihood of successful reception of the data. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is correctly received over communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput in the MAC layer under poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same slot HARQ feedback, where the device may provide HARQ feedback within that slot for data received in previous symbols within a particular slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0147] Compared with other eMBB and URLLC devices, the RedCap UE115 can be associated with lower cost and lower complexity. For example, the RedCap UE115 may have reduced bandwidth capabilities or a reduced minimum number of receive branches. Additionally or alternatively, the RedCap UE115 may be configured with a lower maximum number of downlink MIMO layers, a lower maximum modulation order, or a reduced multiplexing operation capability. As an example, the maximum bandwidth of the Frequency Range 1 (FR1) RedCap UE115 during and after initial access can be 20 MHz, and the maximum bandwidth of the Frequency Range 2 (FR2) RedCap UE115 during and after initial access can be 100 MHz. In some cases, the RedCap UE115 may or may not support carrier aggregation and dual connectivity. The RedCap UE115 may support a stand-alone mode or single connectivity for operation in a single frequency band at a time.

[0148] In the case of frequency bands where other UE115 are equipped with at least two receive antenna ports, the minimum number of receive branches supported by the RedCap UE115 can be set to 1. However, some RedCap UE115 may support two receive branches in these frequency bands. In the case of frequency bands where other UE115 (e.g., other than vehicle UE115 with two receive branches) are equipped with at least four receive antenna ports, the minimum number of receive branches supported by the RedCap UE115 can also be set to 1. However, some RedCap UE115 may similarly support two receive branches in these frequency bands. In some cases, the base station 105 may be able to determine the number of receive branches supported by the UE115.

[0149] A RedCap UE115 with one receive branch may be able to support one downlink MIMO layer. Similarly, a RedCap UE115 with two receive branches may be able to support two downlink MIMO layers. Support for 256QAM in the downlink may be optional (e.g., not mandatory) for FR1 RedCap UE115. Some RedCap UE115 may support half-duplex or frequency division duplex (FDD) type A communication. Other RedCap UE115 may also support full-duplex FDD and time division duplex (TDD).

[0150] Some examples of RedCap UE115 may include wearable devices, connected industrial devices, and smart city devices. Wearable devices may include, among other examples, smartwatches, AR or VR glasses, or eHealth and medical monitoring devices. Wearable devices may have a high downlink reference rate (e.g., 5 - 50 Mbps for the downlink and 2 - 5 Mbps for the uplink), a peak downlink rate of 150 Mbps, and a peak uplink data rate of 50 Mbps. Wearable devices may generally have latency and reliability constraints corresponding to those used for eMBB. The battery life of wearable devices generally lasts for several days (e.g., up to 1 or 2 weeks at most).

[0151] Connected industrial devices can include, among other examples, pressure sensors, humidity sensors, motion sensors, thermal sensors, accelerometers, and actuators. Connected industrial devices can have an uplink heavy reference rate (e.g., 2 Mbps), a latency of less than 100 ms (e.g., 5 - 10 ms for safety - related sensors), a reliability of approximately 99.99%, and a battery life of at least several years. Smart city devices can be used for video surveillance. Smart city devices can have an uplink heavy reference rate (e.g., 2 - 4 Mbps for economy devices, 7.5 - 25 Mbps for high - end devices), a latency of less than 500 ms, and a relatively high reliability (e.g., 99% - 99.9%). The reduced complexity of RedCap devices can enable a device design with a compact form factor. RedCap devices can support all TDD and FDD frequency bands configured for 5G NR.

[0152] Wireless communication system 100 can support SSB transmission in the initial downlink BWP. In FR1, RedCap UE115 can be configured with a first downlink BWP (e.g., the default initial downlink BWP for non - RedCap UEs) that includes all of the resources assigned for CD - SSB reception and CORESET#0. RedCap UE115 can also be configured using a second downlink BWP (e.g., separate from the first downlink BWP). If the second downlink BWP is configured for random access but not for paging in the idle or non - active mode, RedCap UE115 may not expect the second downlink BWP to include resources assigned for SSB reception, resources assigned for CORESET#0, or resources assigned for system information block (SIB) reception.

[0153] For example, when the RedCap UE 115 performs random access in the second downlink BWP, the RedCap UE 115 may not be configured to monitor paging messages in the first downlink BWP including CORESET#0. If the second downlink BWP is configured for paging, the RedCap UE 115 may expect the second downlink BWP to include resources allocated for the RedCap UE to receive NCD-SSB from the serving cell of the RedCap UE, but may not expect the second downlink BWP to include resources allocated for CORESET#0 or SIB reception. For example, if the second downlink BWP (e.g., a separate SIB-configured initial downlink BWP for the RedCap UE) includes all of CORESET#0, the RedCap UE 115 may use the bandwidth and location of CORESET#0 in the downlink during initial access.

[0154] The periodicity of NCD-SSB in the second downlink BWP may be the same as or different from the periodicity of CD-SSB in the first downlink BWP. However, the periodicity of NCD-SSB may not be smaller than the periodicity of CD-SSB. If the second downlink BWP (e.g., a separate initially configured downlink BWP) is configured to include all of CORESET#0, the RedCap UE 115 may expect to receive CD-SSB in the second downlink BWP. In some examples, the network entity may determine to configure the SSB resource, master information block (MIB) configuring CORESET#0, or SIB1 resource such that these resources are located within the second downlink BWP. For some SSB and CORESET#0 multiplexing patterns, if the second downlink BWP (e.g., a separate initially configured downlink BWP) is configured to include all of CORESET#0, the RedCap UE 115 may expect to receive CD-SSB in the second downlink BWP.

[0155] Wireless communication system 100 can support, among other benefits, greater processing efficiency and reduced power consumption in RedCap UE 115. For example, the techniques described herein can reduce the number of control resources (e.g., CORESETs, SSs) configured to be monitored while RedCap UE 115 is operating in idle or inactive mode, which can reduce the processing cost and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by RedCap UE 115. Specifically, the techniques described can reduce the number of blind decoding operations performed by RedCap UE 115, which can enable RedCap UE 115 to perform idle or inactive mode operations with higher processing efficiency (e.g., using fewer processing resources) and reduced power consumption.

[0156] FIG. 2 shows an example of a wireless communication system 200 that supports downlink control channel monitoring in multiple downlink BWPs, according to an aspect of the present disclosure. Wireless communication system 200 may implement or be implemented by aspects of wireless communication system 100. For example, wireless communication system 200 may include a base station 105-a and a UE 115-a that may be examples of corresponding devices described with reference to FIG. 1. The base station 105-a (e.g., a network entity) and the UE 115-a (e.g., a RedCap UE) may communicate within a geographic coverage area 110-a that may be an example of the geographic coverage area 110 described with reference to FIG. 1. In wireless communication system 200, UE 115-a may switch between a first downlink BWP and a second BWP while performing various idle or inactive mode operations.

[0157] In both FR1 and FR2, a separate initial downlink BWP can be configured (e.g., via SIB) for idle or inactive RedCap UEs. This separate initial downlink BWP can be restricted by the maximum bandwidth supported by the RedCap UE. The CD-SSB resource and the MIB-configured CORESET#0 may or may not be located within this separate initial downlink BWP configured for the RedCap UE. If the RedCap-specific initial downlink BWP does not include the entire CORESET#0 configured by the MIB, a separate common CORESET and SS set can be configured within the RedCap-specific initial downlink BWP. For cell search and system information acquisition, an idle or inactive RedCap UE can monitor CORESET#0 and the CSS set for SIB1 and other system information (OSI). The common CORESET and SS set for other idle or inactive mode procedures can be configured in the RedCap-specific initial downlink BWP or within the bandwidth of CORESET#0.

[0158] According to various rules specified for non-RedCap UEs, each downlink BWP can be provided via upper layer signaling in a P≤3 CORESET, when the coresetPoolIndex is not provided, or when the coresetPoolIndex is provided and the value of the coresetPoolIndex is the same for all CORESETs; P≤5 CORESET, when the coresetPoolIndex is not provided for the first CORESET, or when the coresetPoolIndex is provided and the value of the coresetPoolIndex is 0 for the first CORESET and 1 for the second CORESET; and S≤10 search space sets (determined based on the association between the SS set index and the CORESET index).

[0159] In contrast to the SIB 1 configured initial downlink BWP for non-RedCap UEs, the RedCap-specific initial downlink BWP configured via SIB may not include CORESET #0. Therefore, the CORESET and SS set configuration rules may be modified for idle or inactive RedCap UEs. To achieve an appropriate balance between UE complexity reduction and coexistence between different UE types, the techniques described provide an improved PDCCH monitoring procedure for RedCap UEs in idle or inactive mode that is configured to switch between CORESET #0 and the RedCap-specific initial downlink BWP to perform various idle or inactive mode procedures.

[0160] Wireless communication system 200 may support CORESET and SS set configurations that improve the efficiency of downlink channel monitoring for idle or inactive RedCap UEs. For an idle or inactive RedCap UE configured with a separate initial downlink BWP (e.g., different from the downlink BWP including CORESET #0), the bandwidth of the separate initial downlink BWP may be 6 * or more physical resource blocks (PRBs), and the reference numerology for the separate initial downlink BWP may be configured separately from the reference numerology used for CORESET #0. The variable Q may be defined by Equation 1 shown below, where P redcap represents the total number of CORESETs configured in the separate initial downlink BWP of the RedCap UE.

[0161]

Number

[0162] For an idle RedCap UE, P redcap includes the number of CORESETs associated with the CSS set. For a non-active RedCap UE, P redcapIt includes the number of CORESETs associated with the CSS set and the UE-specific search space (USS) set. The CORESET and SS sets associated with the idle or non-active mode procedures can be jointly configured in CORESET #0, similar to the separate initial downlink BWP for RedCap UEs.

[0163] Examples of idle or non-active mode procedures include, among others, SIB1 or OSI acquisition, on-demand transmission of RedCap-specific system information, paging operation, paging early indication (PEI) reception, mobility procedures, random access procedures (e.g., type 1 or type 2 random access procedures), small uplink data transfer based on configured grants or following random access procedures (e.g., type 1 or type 2 random access procedures), or small downlink data transfer triggered by paging messages, multicast messages, or broadcast messages. The PEI can be an example of a PDCCH message that can provide UE power saving in the paging operation. As described herein, the mobility procedures can include cell-level mobility procedures (e.g., cell selection, cell reselection, handover) and TRP-level or beam-level mobility procedures.

[0164] The CORESET and SS sets for idle mode procedures and non-active mode procedures can be configured within the same downlink BWP or distributed across different downlink BWPs. For example, the random access CSS for an idle RedCap UE can be configured in the RedCap-specific initial downlink BWP, while the random access CSS for a non-active RedCap UE can be configured within CORESET #0. Additionally or alternatively, the CSS set for system information acquisition or paging reception by an idle or non-active UE can be configured within CORESET #0.

[0165] The total number of CORESETs and SS sets configured in the MIB - configured CORESET#0 (e.g., P CORESET0 , S CORESET0 ) and a separate initial downlink BWP configured by SIB (e.g., P RedCap , S RedCap ) may be bounded by P0 and S0, where P0 and S0 correspond to the total number of CORESETs and SS sets configured in the downlink BWP of non - RedCap UEs. Specifically, the total number of CORESETs in CORESET#0 and the separate initial downlink BWP may be determined according to the inequality P CORESET0 +P RedCap ≦P0 (e.g., P0≦3), and the total number of SS sets in CORESET#0 and the separate initial downlink BWP may be determined according to the inequality S CORESET0 +S RedCap ≦S0 (e.g., S0≦10).

[0166] The amount of blind decoding candidates for the control channel element (CCE) aggregation level (AL) and the SS sets configured in the RedCap - specific initial downlink BWP can be explicitly provided to the RedCap UE via system information (e.g., in the case of idle and inactive RedCap UEs) or RRC signaling (e.g., in the case of inactive RedCap UEs). The AL for the CSS sets configured in the separate initial downlink BWP can be less than the maximum value (e.g., 4, the minimum AL for the CSS sets configured by SIB1 within CORESET#0). The downlink control information (DCI) size alignment for PDCCH transmission in the SS sets of CORESET#0 and the separate initial downlink BWP can be enabled or disabled via SIB.

[0167] In the example of FIG. 2, base station 105-a may transmit one or more control messages 205 to UE 115-a. The one or more control messages may indicate configurations for a first downlink BWP associated with a first operating mode of UE 115-a, a second downlink BWP associated with a second operating mode of UE 115-a, a first set of resources within the first downlink BWP, and a second set of resources within the second downlink BWP. In some examples, base station 105-a may transmit one or more control messages 205-a to UE 115-a via the first set of resources within the first downlink BWP. Additionally or alternatively, base station 105-a may transmit one or more control messages 205-b to UE 115-a via the second set of resources within the second downlink BWP.

[0168] Base station 105-a may also transmit SSB 210 to UE 115-a via the first set of resources within the first downlink BWP and the second set of resources within the second downlink BWP. For example, base station 105-a may transmit CD-SSB 210-a to UE 115-a via the first set of resources within the first downlink BWP (e.g., while UE 115-a is in the first operating mode), and may transmit NCD-SSB 210-b to UE 115-a via the second set of resources within the second downlink BWP (e.g., while UE 115-a is in the second operating mode). For example, when UE 115-a transitions from the first operating mode to the second operating mode, UE 115-a may perform a BWP switching procedure from the first downlink BWP to the second downlink BWP.

[0169] In some examples, UE115-a may receive a PWS notification 215 from base station 105-a via a second set of resources within a second downlink BWP. Similarly, UE115-a may receive a system information update 220 from base station 105-a via a second set of resources within a second downlink BWP. Base station 105-a may indicate the PWS notification 215 or the system information update 220 via, among other examples, a random access message (e.g., msgB or msg4), a paging message, a downlink small data transmission (SDT) triggered by paging, or a multicast or broadcast physical downlink shared channel (PDSCH) transmission triggered by a PDCCH.

[0170] Wireless communication system 200 may support, among other benefits, greater processing efficiency and reduced power consumption in UE115-a (e.g., a RedCap UE). For example, the techniques described herein may reduce the number of control resources (e.g., CORESET, SS) configured to be monitored while UE115-a is operating in an idle or inactive mode, which may reduce the processing cost and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by UE115-a. Specifically, the techniques described may reduce the number of blind decoding operations performed by UE115-a, which may enable UE115-a to perform idle or inactive mode operations with greater processing efficiency and reduced power consumption (e.g., using fewer processing resources).

[0171] Figures 3A and 3B show examples of resource diagram 300 and resource diagram 301 that support downlink control channel monitoring in a plurality of downlink BWPs according to aspects of the present disclosure. Resource diagram 300 and resource diagram 301 may implement or be implemented by aspects of wireless communication system 100 or wireless communication system 200. For example, resource diagram 300 and resource diagram 301 may implement or be implemented by UE 115 (e.g., a RedCap UE) or base station 105 (e.g., a network entity), which may be examples of corresponding devices described with reference to FIGS. 1 and 2. In resource diagram 300 and resource diagram 301, a RedCap UE in an idle or inactive mode may switch between a first downlink BWP and a second downlink BWP to monitor downlink messages from a network entity.

[0172] Resource diagrams 300 and 301 may support system information updates and PWS notifications for idle and inactive RedCap UEs. For an idle or inactive RedCap UE that performs a random access procedure in a separate initial downlink BWP, if the paging CSS is not configured within the separate initial downlink BWP, the PWS notification and system information update for the RedCap UE may be indicated via msg4 (e.g., in a type-1 random access procedure) or msgB (e.g., in a type-2 random access procedure). However, if the paging CSS is configured within a separate initial downlink BWP for idle and inactive RedCap UEs, the PWS notification and system information update for the RedCap UE can be indicated via a paging message (e.g., a short message or a paging message). Additionally, or alternatively, the PWS notification or system information update can be delivered within the separate initial downlink BWP via downlink small data transmission triggered by paging. The PWS notification and system information update can also be delivered via broadcast or multicast PDSCH transmission scheduled by PDCCH transmission associated with searchSpaceBroadcast (configured within the separate initial downlink BWP).

[0173] In the example of FIG. 3A, the idle RedCap UE may camp on CORESET #0 of the serving cell to receive CD-SSB, system information, paging messages, or a combination thereof. Thus, an idle state RedCap UE can switch to a separate initial downlink BWP to perform random access or to initiate a transition to the connected mode. An idle RedCap UE performing random access in a separate initial BWP may refrain from monitoring paging messages in CORESET #0 before establishing an RRC connection with the network entity. System information updates and PWS notifications for the RedCap UE may be delivered via a scheduled msg4 or msgB transmission in the RedCap-specific initial downlink BWP.

[0174] The idle RedCap UE may be configured to monitor a first downlink BWP for CD-SSB 305. The first downlink BWP may include CORESET #0 310 and one or more CORESETs and CSSs 315 configured for the system information acquisition procedure and the system information update procedure. For example, the idle RedCap UE can receive SIB1 or OSI from the network entity via one or more CORESETs and CSSs 315. In some examples, the idle RedCap UE may execute a BWP switching procedure from the first downlink BWP to the second downlink BWP based on transitioning from the first operating mode to the second operating mode. The second downlink BWP may include one or more CORESETs and CSSs 320 configured for initial access, an initial downlink BWP 325 configured for the RedCap UE, one or more physical uplink shared channel (PUCCH) resources 330, an initial uplink BWP 335, and one or more random access channel (RACH) opportunities 340.

[0175] In the example of FIG. 3B, an idle or inactive RedCap UE may receive CD-SSB and system information in CORESET#0. The idle or inactive RedCap UE may also receive NCD-SSB and monitor paging messages in a separate initial downlink BWP. Instructions for system information updates or PWS notifications may be delivered to the idle or inactive RedCap UE via paging messages or short messages. Additionally, or alternatively, system information updates and PWS notifications can be delivered to the idle or inactive RedCap UE via downlink small data transmissions triggered by paging messages. The idle or inactive RedCap UE may also receive system information updates and PWS notifications via one or more broadcast transmissions, multicast transmissions, PDCCH transmissions, or PDSCH transmissions associated with searchSpaceBroadcast configured in a separate initial downlink BWP.

[0176] An idle or non-active RedCap UE may be configured to monitor a first downlink BWP for CD-SSB 345. The first downlink BWP may include CORESET#0 350 and one or more CORESETs and CSSs 355 configured for system information acquisition procedures and system information update procedures. For example, an idle or non-active RedCap UE may receive SIB1 or OSI from a network entity via one or more CORESETs and CSSs 355. In some examples, an idle or non-active RedCap UE may execute a BWP switching procedure from the first downlink BWP to the second downlink BWP based on transitioning from a first operating mode to a second operating mode. An idle or non-active RedCap UE may be configured to monitor a second downlink BWP for NCD-SSB 360. The second downlink BWP may include one or more CORESETs and CSSs 365 configured for paging and multicast broadcast service (MBS), an initial downlink BWP 370 configured for the RedCap UE, one or more PUCCH resources 375, and an initial uplink BWP 380.

[0177] Resource diagrams 300 and 301 can support, among other benefits, greater processing efficiency and reduced power consumption in a RedCap UE. For example, the techniques described herein can reduce the number of control resources (e.g., CORESETs, SSs) configured to be monitored while the RedCap UE is operating in an idle or inactive mode, which can reduce the processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by the RedCap UE. Specifically, the techniques described can reduce the number of blind decoding operations performed by the RedCap UE, which can enable the RedCap UE to perform idle or inactive mode operations with greater processing efficiency (e.g., using fewer processing resources) and reduced power consumption.

[0178] Figure 4 shows an example of a process flow 400 that supports downlink control channel monitoring in multiple downlink BWPs, according to an aspect of the present disclosure. Process flow 400 may implement or be implemented by aspects of wireless communication system 100 or wireless communication system 200. For example, process flow 400 may include base station 105-b (e.g., a network entity) and UE 115-b (e.g., a RedCap UE), which may be examples of corresponding devices described with reference to FIGS. 1 and 2. In the following description of process flow 400, the operations between UE 115-b and base station 105-b may be performed in a different order or at different times than shown. Additionally or alternatively, some operations may also be omitted from process flow 400, and other operations may be added to process flow 400. In the example of FIG. 4, UE 115-b (e.g., an idle or inactive RedCap UE) may be configured to monitor a first downlink BWP and a second downlink BWP for downlink messages from base station 105-b.

[0179] At 405, UE 115-b may receive one or more control messages from base station 105-b indicating configurations for a first downlink BWP associated with a first operation mode of UE 115-b, a second downlink BWP associated with a second operation mode of UE 115-b, a first set of control resources within the first downlink BWP, and a second set of control resources within the second downlink BWP. For example, UE 115-b may receive a MIB indicating a configuration for the first downlink BWP and the first set of control resources. Similarly, UE 115-b may receive an SIB, a dedicated RRC message, a multicast message, or a broadcast message indicating a configuration for the second downlink BWP and the second set of control resources. In some examples, the first downlink BWP and the second downlink BWP may correspond to different frequency ranges (e.g., within a carrier bandwidth).

[0180] At least a portion of the configuration may correspond to the capabilities of UE 115-b or the operation mode of UE 115-b. In some examples, both the first operation mode of UE 115-b and the second operation mode of UE 115-b may correspond to the same RRC state. For example, the first operation mode of UE 115-b and the second operation mode of UE 115-b may correspond to the RRC idle state (RRC_IDLE) or the RRC inactive state (RRC_INACTIVE) of UE 115-b. In such examples, the first set of control resources within the first downlink BWP and the second set of control resources within the second downlink BWP may include CSSs and may exclude other SSs. In other examples, the first operation mode of UE 115-b and the second operation mode of UE 115-b may correspond to the RRC inactive state (RRC_INACTIVE) or the RRC connected state (RRC_CONNECTED) of UE 115-b. In such examples, the first set of control resources within the first downlink BWP and the second set of control resources within the second downlink BWP may include CSSs, USSs, or both.

[0181] One or more control messages may also indicate one or both of a first set of parameters related to the first downlink BWP or a second set of parameters related to the second downlink BWP. The first set of parameters may include the bandwidth, initial PRB location, numerology, or a combination thereof associated with the first downlink BWP, and the second set of parameters may include the bandwidth, initial PRB location, numerology, or a combination thereof associated with the second downlink BWP. In some examples, the first set of parameters may be different from the second set of parameters. Additionally or alternatively, one or more control messages may indicate the amount of PRBs in the second downlink BWP, which may be based on the CCE AL of the CORESET in the second downlink BWP, the duration of the CORESET in the second downlink BWP, the total amount of the CORESET in the second downlink BWP, the RRC state of UE115-b, or a combination thereof. One or more control messages may also include a system information message, an RRC message, a broadcast message, or a multicast message indicating the CCE AL for the SS set in the second downlink BWP, the amount of blind decoding candidates for the SS set in the second downlink BWP, or both.

[0182] At 410, UE 115-b may determine the amount of control resources (e.g., CORESET, SS) within a second downlink BWP based on the amount of control resources in the first downlink BWP, the total of control resources in different downlink BWPs of UE 115-b, and a threshold amount of control resources related to the capabilities of UE 115-b. In some examples, the first downlink BWP may include a first CSS configured for a cell selection procedure or a cell reselection procedure by a UE in the RRC idle state or the RRC inactive state. The first downlink BWP may also include one or more CSSs configured for a system information acquisition procedure, a system information update procedure, a mobility procedure, or a paging reception procedure by a UE in the RRC idle state or the RRC inactive state. Additionally or alternatively, the second downlink BWP may include a second CSS configured for a random access procedure or a paging reception procedure by a UE in the RRC idle state or the RRC inactive state.

[0183] At 415, UE 115-b may monitor a first set of control resources within the first downlink BWP while UE 115-b is in a first operating mode. UE 115-b may monitor the first set of control resources according to the configuration and based on the capabilities of UE 115-b. In some examples, UE 115-b may use the CORESET and SS within the first downlink BWP to execute one or more procedures associated with the first operating mode of UE 115-b. For example, UE 115-b may use the first set of control resources within the first downlink BWP to execute one or more of a system information update procedure, a mobility procedure, a paging reception procedure (also referred to as a paging operation), a random access procedure, a small data transfer procedure, or an on-demand system information transmission request procedure.

[0184] At 420, UE 115-b may receive one or more messages from base station 105-b via a first set of control resources within the first downlink BWP. For example, UE 115-b may receive an SIB indicating one or more of an AL, a monitoring period, or a monitoring occasion configuration for a CSS set within the second downlink BWP, based on the capabilities of UE 115-b. Additionally or alternatively, UE 115-b may receive, via the first set of control resources within the first downlink BWP associated with the first operating mode of UE 115-b, a CD-SSB, a system information message, a paging message, a PEI message, a random access message, or a combination thereof (during the first operating mode), from base station 105-b. UE 115-b may also receive an SIB indicating a first DCI size alignment for PDCCH messages at the SS of the first downlink BWP, a second DCI size alignment for PDCCH messages at the SS of the second downlink BWP, or both.

[0185] At 425, UE 115-b may execute a BWP switching procedure from the first downlink BWP to the second BWP, based on transitioning from the first operating mode to the second operating mode. At 430, UE 115-b may monitor a second set of control resources within the second downlink BWP while UE 115-b is in the second operating mode. UE 115-b may monitor the second set of control resources according to the configuration and based on the capabilities of UE 115-b. In some examples, UE 115-b may use a CORESET and an SS within the second downlink BWP to execute one or more procedures associated with the second operating mode of UE 115-b. For example, UE 115-b may use the second set of control resources within the second downlink BWP to execute one or more of a system information update procedure, a mobility procedure, a paging reception procedure, a random access procedure, a small data transfer procedure, or an on-demand system information transmission request procedure.

[0186] At 435, UE 115-b may receive one or more messages from base station 105-b via a second set of control resources within the second downlink BWP. For example, UE 115-b may receive from base station 105-b, via a second set of control resources within the second downlink BWP, a random access message, a system information message, a multicast message, a broadcast message, a paging message, SDT (e.g., uplink or downlink), or one or more of NCD-SSB. As described with reference to FIG. 5, UE 115-b may also receive a system information update or a PWS notification from base station 105-b via a second set of control resources within the second downlink BWP.

[0187] Process flow 400 may support, among other benefits, greater processing efficiency and reduced power consumption in UE 115-b (e.g., a RedCap UE). For example, the techniques described herein may reduce the number of control resources (e.g., CORESET, SS) configured to be monitored while UE 115-b is operating in an idle or inactive mode, which may reduce the processing cost and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by UE 115-b. Specifically, the techniques described may reduce the number of blind decoding operations performed by UE 115-b, which may enable UE 115-b to perform idle or inactive mode operations with greater processing efficiency and reduced power consumption (e.g., using fewer processing resources).

[0188] FIG. 5 illustrates an example of a process flow 500 that supports downlink control channel monitoring in multiple downlink BWPs according to an aspect of the present disclosure. The process flow 500 may implement or be implemented by aspects of the wireless communication system 100 or the wireless communication system 200. For example, the process flow 500 may include a base station 105-c (e.g., a network entity) and a UE 115-c (e.g., a RedCap UE) that may be examples of corresponding devices described with reference to FIGS. 1 and 2. In the following description of the process flow 500, the operations between the UE 115-c and the base station 105-c may be performed in an order different from that shown or at different times. Additionally or alternatively, some operations may also be omitted from the process flow 500, and other operations may be added to the process flow 500. In the example of FIG. 5, the UE 115-c may receive a system information update or a PWS notification from the base station 105-c via resources in a downlink BWP configured for an idle or inactive RedCap UE.

[0189] At 505, UE 115-c may receive one or more control messages from base station 105-c. The one or more control messages may indicate configurations for a first downlink BWP associated with a first operation mode of the UE, a second downlink BWP associated with a second operation mode of the UE, a first set of resources within the first downlink BWP, and a second set of resources within the second downlink BWP. At least a portion of the configuration may correspond to the capabilities of UE 115-c. At 510, UE 115-c may monitor the first set of resources within the first downlink BWP while UE 115-c is in the first operation mode. UE 115-c may monitor the first set of resources according to the configuration (indicated by the one or more control messages) and based on the capabilities of UE 115-c. At 515, UE 115-c may receive one or more messages from base station 105-c via the first set of resources within the first downlink BWP. UE 115-c may receive the one or more messages according to the configuration and based on the capabilities of UE 115-c.

[0190] At 520, UE 115-c may execute a BWP switching procedure from the first downlink BWP to the second downlink BWP based on transitioning from the first operation mode to the second operation mode. In some examples, the first operation mode and the second operation mode may correspond to the same RRC state. For example, the first operation mode and the second operation mode may correspond to the RRC idle state (e.g., RRC_IDLE) or the RRC inactive state (RRC_INACTIVE). In other words, UE 115-c may transition between different operation modes while remaining in the same RRC state. These different operation modes may be associated with different downlink BWPs. At 525, UE 115-c may monitor the second set of resources within the second downlink BWP (e.g., while UE 115-c is in the second operation mode). UE 115-c may monitor the second set of resources within the second downlink BWP according to the configuration and based on the capabilities of UE 115-c.

[0191] In some examples, UE115-c may perform a random access procedure with base station 105-c at 530 (while in the second operating mode). UE115-c may perform the random access procedure via a second set of resources within the second downlink BWP. At 535, UE115-c may receive a system information update from base station 105-c via a second set of resources within the second downlink BWP. At 540, UE115-c may receive a PWS notification from base station 105-c via a second set of resources within the second downlink BWP. In some examples, UE115-c may receive a system information update or a PWS notification via a random access message (e.g., msgB or msg4) that base station 105-c may transmit during the random access procedure (e.g., via a second set of resources within the second downlink BWP).

[0192] For example, if the second downlink BWP does not include a CSS configured for paging operation, the base station 105-c may send a system information update or a PWS notification via a random access message. If the second downlink BWP includes a CSS configured for paging operation, the base station 105-c may indicate a system information update or a PWS notification via a paging message. In other examples, the base station 105-c may indicate a system information update or a PWS notification via an SDT triggered by paging. For example, the base station 105-c may send a paging message that schedules a downlink SDT from the base station 105-c (e.g., via a second set of resources within the second downlink BWP). The base station 105-c can send a downlink SDT according to the paging message and can include a system information update or a PWS notification in the downlink SDT. Similarly, the base station 105-c may send a PDCCH message that schedules a broadcast or multicast PDSCH message from the base station 105-c (e.g., via a second set of resources within the second downlink BWP). The base station 105-c may send a broadcast or multicast PDSCH message according to the PDCCH message and may include a system information update or a PWS notification in the broadcast or multicast PDSCH message.

[0193] The process flow 500 may support, among other benefits, greater processing efficiency and reduced power consumption in UE115-c (e.g., a RedCap UE). For example, the techniques described herein may reduce the number of control resources (e.g., CORESET, SS) configured to be monitored while UE115-c is operating in an idle or inactive mode, which may reduce the processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by UE115-c. Specifically, the techniques described may reduce the number of blind decoding operations performed by UE115-c, which may enable UE115-c to perform idle or inactive mode operations with greater processing efficiency and reduced power consumption (e.g., using fewer processing resources).

For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or optical particles, or any combination thereof.

[0418] The various illustrative blocks and components described in connection with the present disclosure herein may be implemented or executed using a general purpose processor, DSP, ASIC, CPU, GPU, FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein.

When implemented in software executed by at least one processor, the functions may be stored on a computer-readable medium or transmitted via a computer-readable medium as one or more instructions or code. Other examples and implementation forms are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described in this specification may be implemented using software executed by at least one processor, hardware, hardwiring, or any combination thereof. The features implementing the functions may also be physically located in various places, including being distributed such that parts of the functions are implemented at different physical locations.

[0420] A computer-readable medium includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another.

Also, "determining" or "identifying" can include receiving (receiving information or signaling, e.g., receiving information or signaling for determining, receiving information or signaling for identifying, etc.) or accessing (accessing data in memory, or accessing information, etc.). Further, "determining" or "identifying" can include solving, selecting, choosing, establishing, and other similar acts.

[0423] In the accompanying figures, similar components or features may have the same reference labels. Further, various components of the same type can be distinguished by attaching a dash and a second label that distinguishes the similar components after the reference label. If only the first reference label is used herein, the description is applicable to any of the similar components having the same first reference label regardless of the second reference label or any other subsequent reference labels.

[0424] The description set forth in this specification with respect to the accompanying drawings describes exemplary configurations and does not represent all examples that may be implemented or fall within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration" and does not mean "preferred" or "advantageous over other examples". The detailed description includes specific details for bringing about an understanding of the described techniques. However, these techniques may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.

[0425] The description of this specification is provided to enable a person skilled in the art to make or use the present disclosure. Various modifications to the present 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 the present disclosure.
