[0001] cross reference This patent application claims the benefit of U.S. Patent Application No. 18,061,347 to LEI et al., entitled "DOWNLINK CONTROL CHANNEL MONITORING IN MULTIPLE DOWNLINK BANDWIDTH PARTS," filed December 2, 2022, which claims priority to U.S. Provisional Patent Application No. 63 / 297,691 to LEI et al., entitled "DOWNLINK CONTROL CHANNEL MONITORING IN MULTIPLE DOWNLINK BANDWIDTH PARTS," filed January 7, 2022, each of which is assigned to the assignee of the present application and expressly incorporated herein by reference.
[0002] The following relates to wireless communications that involve downlink control channel monitoring in multiple downlink bandwidth portions (BWPs). [Background technology]
[0003] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasts, etc. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE) systems, LTE-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 technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communication system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may sometimes be known as User Equipment (UE). The components within a wireless communication system may be coupled (e.g., operatively, communicatively, functionally, electronically, and / or electrically) with one another.
[0004] An idle or inactive UE may be configured to monitor resources in different bandwidth portions (BWPs). For example, an idle or inactive 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 greater power consumption and higher processing overhead in the UE. Summary of the Invention
[0005] The described technology relates to improved methods, systems, devices, and apparatuses that support downlink control channel monitoring in multiple downlink bandwidth portions (BWPs). Generally, the described technology provides for improving the efficiency of downlink monitoring procedures in idle or inactive user equipment (UE). The UE may receive one or more control messages from a network entity indicating configurations for a first downlink BWP associated with a first mode of operation of the UE, a second downlink BWP associated with a second mode of operation 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 configurations may correspond to UE capabilities. The UE may monitor the first set of resources while in the first mode of operation and may monitor the second set of resources while in the second mode of operation. The UE may receive system information updates or public warning system (PWS) notifications from the network entity via the second set of resources. The techniques described herein may enable a UE (e.g., an idle or inactive UE) to perform downlink channel monitoring with reduced power consumption and greater processing efficiency, among other benefits.

DETAILED DESCRIPTION OF THE INVENTION
[0104] Compared to other user equipment (UEs), a reduced capability (RedCap) UE may be associated with reduced processing power, higher battery life, and lower overall cost. Therefore, a RedCap UE may be suitable for Internet of Things (IoT), augmented reality (AR), virtual reality (VR), and vehicle-to-everything (V2X) applications, among other examples. In some cases, a RedCap UE in idle or inactive mode may be configured to monitor a first downlink bandwidth portion (BWP) for system information updates, paging messages (e.g., paging operation messages), or cell-defined (CD) synchronization signal blocks (SSBs) from a network entity. The RedCap UE may also be configured with a second, initial downlink BWP that may be specific to the RedCap UE. The RedCap UE may monitor the second downlink BWP for random access messages, paging messages, or non-cell-defined (NCD) SSBs from a network entity.
[0105] However, if 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 may result in greater power consumption and reduced processing efficiency in the RedCap UE. For example, the RedCap UE may perform a relatively large number of blind decoding operations (e.g., monitoring the downlink channel for notification and scheduling information) on resources in the first downlink BWP and resources in the second downlink BWP, even if the RedCap UE is not scheduled to receive downlink transmissions from a network entity on these resources.
[0106] To reduce processing costs and power consumption associated with downlink monitoring procedures for idle or inactive RedCap UEs, the total number of control resources in the first downlink BWP and the second downlink BWP (e.g., downlink BWPs configured for RedCap UEs) may be constrained by a threshold number of control resource sets (CORESETs) and a threshold number of search spaces (SSs). For example, a network entity may configure the first downlink BWP and the second downlink BWP such that the total number of CORESETs and SSs in the first downlink BWP and the second downlink BWP is less than a threshold. In some examples, the total number of CORESETs and SSs in the first downlink BWP and the second downlink BWP may depend on the capabilities of the non-RedCap UE.
[0107] A network entity (e.g., a base station) may configure the RedCap UE with 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 may monitor both the first downlink BWP and the second downlink BWP according to information provided by the network entity. In some examples, the network entity may send a system information update or a public warning system (PWS) notification to the RedCap UE via resources in the second downlink BWP.
[0108] Aspects of the present disclosure may be implemented to achieve one or more of the following advantages: The described techniques may support greater processing efficiency and reduced power consumption in a RedCap UE, among other benefits. For example, the described techniques may reduce the number of control resources (e.g., CORESETs, SSs) that a RedCap UE is configured to monitor while operating in an idle or inactive mode, which may reduce processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by the RedCap UE. Specifically, the described techniques may reduce the number of blind decoding operations performed by the RedCap UE, which may enable the RedCap UE to perform idle or inactive mode operation with greater processing efficiency (e.g., using fewer processing resources) and reduced power consumption.
[0109] Aspects of the present disclosure are initially described in the context of wireless communication systems, 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 relating to downlink control channel monitoring in multiple downlink BWPs.
[0110] 1 illustrates an example of a wireless communication system 100 supporting downlink control channel monitoring in multiple 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 enhanced broadband communications, ultra-reliable communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.
[0111] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different types or 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 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.
[0112] The UEs 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be fixed or mobile. The UEs 115 may also be referred to as mobile devices, wireless devices, remote devices, handheld devices, or subscriber devices, or some other suitable terminology, and a "device" may also be referred to as a unit, station, terminal, or client. The UEs 115 may be cellular phones, smartphones, personal digital assistants (PDAs), or other devices. The wireless communication device may be a device such as a wireless assistant, PDA, multimedia / entertainment device (e.g., radio, MP3 player, video device), camera, game console, navigation / positioning device (e.g., a GNSS (Global Navigation Satellite System) device, e.g., based on GPS (Global Positioning System), Beidou, GLONASS, or Galileo, a ground-based device), tablet computer, laptop computer, netbook, smartbook, personal computer, smart device, wearable device (e.g., smart watch, smart clothing, smart glasses, virtual reality goggles, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), drone, robot / robotic device, vehicle, vehicular device, meter (e.g., parking meter, electric meter, gas meter, water meter), monitor, gas pump, home appliance (e.g., kitchen appliance, washer, dryer), location tag, medical / healthcare device, implant, sensor / actuator, 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, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, which may be implemented in various items such as an appliance, a drone, a robot, a vehicle, or a meter.
[0113] In some examples, one or more components of the wireless communication system 100 may operate as or be referred to as a network node. As used herein, a network node may refer to any UE 115, base station 105, core network 130 entity, apparatus, device, or computing system configured to perform any of the techniques described herein. For example, a network node may be a UE 115. As another example, a 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 other aspects of this example, the first network node, the second network node, and the third network node may be different. Similarly, reference to a UE 115, a base station 105, an apparatus, a device, or a computing system may include disclosure of the UE 115, the base station 105, the apparatus, the device, or the computing system being a network node. For example, 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, a first network node may refer to a first UE 115, a first base station 105, a first apparatus, a first device, or a first computing system configured to receive information, and a second network node may refer to a second UE 115, a second base station 105, a second apparatus, a second device, or a second computing system.
[0114] The base stations 105 may communicate with the core network 130, or with each other, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface). The base stations 105 may communicate with each other via the backhaul links 120 (e.g., via an X2, Xn, or other interface), either directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or include one or more wireless links.
[0115] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, 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 terminology.
[0116] The UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, and a “device” may also be referred to as a unit, a station, a terminal, or a client, among various examples. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among various examples, which may be implemented in various items, such as an appliance, a vehicle, a meter, or the like, among various examples.
[0117] The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may act as relays, as shown in FIG. 1, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among various examples.
[0118] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on 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 the communication link 125. For example, a carrier used for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., BWP) operated 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 coordinating operation on the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.
[0119] In some examples (e.g., in carrier aggregation configurations), a carrier may also have acquisition or control signaling to coordinate 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 the UE 115. A carrier may operate in a standalone mode, where initial acquisition and connection may be made by the UE 115 via the carrier, or the carrier may operate in a non-standalone mode, where connection is anchored using a different carrier (e.g., of the same or different radio access technology).
[0120] The communication links 125 shown in the wireless communication system 100 may include uplink transmissions from the UE 115 to the base station 105 or downlink transmissions from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry downlink and uplink communications (e.g., in TDD mode).
[0121] A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths for a particular radio access technology carrier (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base stations 105, UEs 115, or both) may have a hardware configuration that supports communication over a particular carrier bandwidth or may be configurable to support communication over one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base stations 105 or UEs 115 that support simultaneous communication over carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over a portion (e.g., a sub-band, BWP) or all of the carrier bandwidth.
[0122] A signal waveform transmitted on a carrier may 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 employing MCM techniques, a resource element may consist of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and 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). Thus, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. 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 may further increase data rates or data integrity for communications with UE 115.
[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 may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 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 UE 115 may be limited to one or more active BWPs.
[0124] The time interval for the base station 105 or the UE 115 is, for example, T s =1 / (Δf max N f) seconds, where Δf max may represent the maximum supported subcarrier spacing, and N f may represent the maximum supported discrete Fourier transform (DFT) size. The communication resource time intervals may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).
[0125] Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, 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 a cyclic prefix prepended to each symbol period). In some wireless communication systems, a slot may be further divided into multiple minislots, each containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the frequency band of operation.
[0126] A subframe, slot, minislot, 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 in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., among bursts of shortened TTIs (sTTIs)).
[0127] Physical channels may be multiplexed on carriers according to various techniques. Physical control channels and physical data channels may be multiplexed on downlink carriers using, for example, one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a CORESET) for a physical control channel may be defined by a number of symbol periods and may span the system bandwidth of the carrier 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 monitor or search the control region for control information according to one or more SS sets, where each SS set may include one or more control channel candidates in one or more aggregation levels (ALs) arranged in a cascaded manner. An AL for a control channel candidate may refer to a number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The SS sets may include a common search space set (CSS) configured to send control information to multiple 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, e.g., macro cells, small cells, hot spots, 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., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) to distinguish neighboring cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of a geographic coverage area 110 in which the logical communication entity operates. Such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area, depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include, among other things, a building, a subset of a building, or an outer space between or overlapping with the geographic coverage area 110.
[0129] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 115 with a service subscription with the network provider that supports the macro cell. Small cells may be associated with lower-power base stations 105 compared to macro cells, and the small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as the macro cell. A small cell may provide unrestricted access to UEs 115 with a service subscription with the network provider, or may provide restricted access to UEs 115 that have an association with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in their homes or offices). A base station 105 may support one or more cells and 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, the base stations 105 may be mobile and therefore may provide communication coverage to moving geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, although the 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. The 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 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 may include communication from devices that incorporate sensors or meters to measure or capture information and relay that information to a central server or application program that can utilize the information or present the information to a human interacting with the program or application. Some UEs 115 may be designed to collect information or enable automated behavior of machinery. Examples of applications for MTC devices 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 technology disclosed herein may be applicable to MTC UEs or IoT UEs 115. An MTC UE or IoT UE 115 may include an MTC / enhanced MTC (eMTC, also referred to as category (CAT)-M, CAT M1) UE, an NB-IoT (also referred to as CAT NB1) UE 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 enhanced eMTC), and mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).
[0133] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communication (e.g., modes that support one-way communication via transmission or reception, but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating over a limited bandwidth (e.g., pursuant to 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 a carrier, or outside a carrier.
[0134] The wireless communication system 100 may be configured to support ultra-reliable or low-latency communications, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communications (URLLC). The UE 115 may be designed to support ultra-reliable, low-latency, or critical functionality. Ultra-reliable communications may include private or group communications and may be supported by one or more services such as push-to-talk, video, data, etc. Support for ultra-reliable, low-latency functionality may include service prioritization, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0135] In some examples, the 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 utilizing 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 may not be able to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, the base station 105 facilitates 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 between vehicles (e.g., UEs 115), such as a sidelink communication channel. In some examples, the vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. The vehicles may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, the vehicles in the V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., base stations 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, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5G core, 5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (PDN gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnects to external networks. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be forwarded through a user plane entity, which may provide IP address allocation and other functions. The user plane entity may connect to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, an intranet, IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0138] Some of the network devices, such as the base stations 105, may include subcomponents, such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transmitting entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, 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., the base station 105).
[0139] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The 300 MHz to 3 GHz region is commonly known as the ultra-high frequency (UHF) region or decimeter band because wavelengths range in length from approximately 1 decimeter to 1 meter. Although UHF waves may be blocked or redirected by buildings and environmental features, the waves can penetrate structures sufficiently for a macrocell to provide service to UEs 115 located indoors. Transmission of UHF waves may involve smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using lower frequencies and longer waves in the shortwave (high frequency (HF)) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0140] The wireless communication system 100 may also operate in the super high frequency (SHF) region, also known as the centimeter band, using the frequency band from 3 GHz to 30 GHz, or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as the millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas on each device may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, propagation of EHF transmissions may experience greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The techniques disclosed herein may be employed over transmissions using one or more different frequency ranges, and the designated use of bands across these frequency ranges may vary by country or regulatory body.
[0141] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may utilize License Assisted Access (LAA), LTE-Unlicensed (LTE-U), or NR technology in an unlicensed band, such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 may utilize carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA). Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[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) communications, or beamforming. The antennas of the base station 105 or the UE 115 may be located in 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 collocated 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 in various geographic locations. The base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 can use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted through the antenna ports.
[0143] A base station 105 or a UE 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques are sometimes referred to as spatial multiplexing. Multiple signals may be transmitted by a transmitting device via, for example, different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple 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). 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 multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.
[0144] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming may be achieved by combining signals communicated through antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjusting signals communicated through antenna elements may include the transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals carried through the antenna elements associated with the device. The adjustment associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or to some other orientation).
[0145] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. The Radio Link Control (RLC) layer may perform packet segmentation and reassembly for communications on logical channels. The Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels onto transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer and improve link efficiency. In the control plane, the RRC protocol layer may establish, configure, and maintain an RRC connection between the UE 115 and the base station 105 or core network 130, which supports radio bearers for user plane data. In the physical layer, transport channels may be mapped to physical channels.
[0146] The UE 115 and the 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 will be correctly received over the communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which the device may provide HARQ feedback in a particular slot for data received in a previous symbol within that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.
[0147] Compared to other eMBB and URLLC devices, the RedCap UE 115 may be associated with lower cost and lower complexity. For example, the RedCap UE 115 may have reduced bandwidth capabilities or a reduced minimum number of receive branches. Additionally or alternatively, the RedCap UE 115 may be configured with a lower maximum number of downlink MIMO layers, a lower maximum modulation order, or reduced duplex operation capabilities. As an example, the maximum bandwidth of the Frequency Range 1 (FR1) RedCap UE 115 during and after initial access may be 20 MHz, and the maximum bandwidth of the Frequency Range 2 (FR2) RedCap UE 115 during and after initial access may be 100 MHz. In some cases, the RedCap UE 115 may or may not support carrier aggregation and dual connectivity. The RedCap UE 115 may support standalone mode or single connectivity for operation in a single frequency band at a time.
[0148] For frequency bands in which other UEs 115 are equipped with at least two receive antenna ports, the minimum number of receive branches supported by a RedCap UE 115 may be set to 1. However, some RedCap UEs 115 may support two receive branches in these frequency bands. For frequency bands in which other UEs 115 (e.g., other than a vehicular UE 115 with two receive branches) are equipped with at least four receive antenna ports, the minimum number of receive branches supported by a RedCap UE 115 may also be set to 1. However, some RedCap UEs 115 may support two receive branches in these frequency bands as well. In some cases, the base station 105 may be able to determine the number of receive branches supported by the UE 115.
[0149] A RedCap UE 115 with one receive branch may be capable of supporting one downlink MIMO layer. Similarly, a RedCap UE 115 with two receive branches may be capable of supporting two downlink MIMO layers. Support for 256QAM in the downlink may be optional (e.g., not required) for FR1 RedCap UEs 115. Some RedCap UEs 115 may support half-duplex or frequency division duplex (FDD) Type A communication. Other RedCap UEs 115 may also support full-duplex FDD and time division duplex (TDD).
[0150] Some examples of RedCap UE 115 may include wearable devices, connected industrial devices, and smart city devices. Wearable devices may include smart watches, AR or VR glasses, or eHealth and medical monitoring devices, among other examples. Wearable devices may have downlink-heavy base rates (e.g., 5-50 Mbps for downlink and 2-5 Mbps for 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 that correspond to those used for eMBB. Battery life of wearable devices typically lasts for multiple days (e.g., up to one or two weeks).
[0151] Connected industrial devices may include pressure sensors, humidity sensors, motion sensors, heat sensors, accelerometers, and actuators, among other examples. Connected industrial devices may have uplink heavy base rates (e.g., 2 Mbps), latency of less than 100 ms (e.g., 5-10 ms for safety-related sensors), approximately 99.99% reliability, and battery life of at least several years. Smart city devices may be used for video surveillance. Smart city devices may have uplink heavy base rates (e.g., 2-4 Mbps for economy devices and 7.5-25 Mbps for high-end devices), latency of less than 500 ms, and relatively high reliability (e.g., 99%-99.9%). The reduced complexity of RedCap devices may enable device designs with compact form factors. RedCap devices can support all TDD and FDD frequency bands configured for 5G NR.
[0152] The wireless communication system 100 may support SSB transmission in an initial downlink BWP. In FR1, the RedCap UE 115 may be configured with a first downlink BWP (e.g., a default initial downlink BWP for non-RedCap UEs) that includes resources allocated for CD-SSB reception and all of CORESET#0. The RedCap UE 115 may also be configured with 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 idle or inactive mode, the RedCap UE 115 may not expect the second downlink BWP to include resources allocated for SSB reception, CORESET#0, or system information block (SIB) reception.
[0153] For example, if the RedCap UE 115 performs random access in the second downlink BWP, the RedCap UE 115 may not be configured to monitor for paging messages in the first downlink BWP that includes 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 receiving NCD-SSBs from the RedCap UE's serving cell, 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 the NCD-SSB in the second downlink BWP may be the same as or different from the periodicity of the CD-SSB in the first downlink BWP. However, the periodicity of the NCD-SSB need not be less than the periodicity of the 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 the CD-SSB in the second downlink BWP. In some examples, the network entity may determine to configure SSB resources, master information block (MIB) configuration CORESET#0, or SIB1 resources 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 the CD-SSB in the second downlink BWP.
[0155] The wireless communication system 100 may support, among other benefits, greater processing efficiency and reduced power consumption in the RedCap UE 115. For example, the techniques described herein may reduce the number of control resources (e.g., CORESETs, SSs) that the RedCap UE 115 is configured to monitor while operating in an idle or inactive mode, which may reduce processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by the RedCap UE 115. Specifically, the described techniques may reduce the number of blind decoding operations performed by the RedCap UE 115, which may enable the RedCap UE 115 to perform idle or inactive mode operation with greater processing efficiency (e.g., using fewer processing resources) and reduced power consumption.
[0156] 2 illustrates an example wireless communication system 200 that supports downlink control channel monitoring in multiple downlink BWPs in accordance with aspects of the present disclosure. The wireless communication system 200 may implement or be implemented by aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a base station 105-a and a UE 115-a, which 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, which may be an example of the geographic coverage area 110 described with reference to FIG. 1. In the wireless communication system 200, the 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 may be configured (e.g., via SIB) for idle or inactive RedCap UEs. This separate initial downlink BWP may be constrained by the maximum bandwidth supported by the RedCap UE. CD-SSB resources and MIB configuration 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 may be configured within the RedCap-specific initial downlink BWP. For cell search and system information acquisition, an idle or inactive RedCap UE may monitor CORESET#0 and CSS sets for SIB1 and other system information (OSI). Common CORESET and SS sets for other idle or inactive mode procedures may 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 may be provided via higher layer signaling with P≦3 CORESET if coresetPoolIndex is not provided or if coresetPoolIndex is provided and the value of coresetPoolIndex is the same for all CORESETs, P≦5 CORESET if coresetPoolIndex is not provided for the first CORESET or if coresetPoolIndex is provided and the value of 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 SS set index and 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. Accordingly, 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 described techniques provide an improved PDCCH monitoring procedure for RedCap UEs in idle or inactive mode that are configured to switch between CORESET#0 and the RedCap-specific initial downlink BWP to perform various idle or inactive mode procedures.
[0160] The 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 idle or inactive RedCap UEs 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 * There may be more than Q 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 denotes the total number of CORESETs configured in the distinct initial downlink BWPs of the RedCap UE.
[0161]
number
[0162] For idle RedCap UEs, P redcap contains the number of CORESETs associated with the CSS set. For inactive RedCap UEs, P redcapcontains the number of CORESETs associated with the CSS set and UE specific search space (USS) set. The CORESET and SS set associated with the idle or inactive mode procedure may be jointly configured in CORESET#0 as well as a separate initial downlink BWP for RedCap UEs.
[0163] Examples of idle or inactive mode procedures include, among other examples, SIB1 or OSI acquisition, on-demand transmission of RedCap-specific system information, paging operations, paging early indication (PEI) reception, mobility procedures, random access procedures (e.g., Type 1 or Type 2 random access procedures), small uplink data transfers based on configured grants or following random access procedures (e.g., Type 1 or Type 2 random access procedures), or small downlink data transfers triggered by paging messages, multicast messages, or broadcast messages. PEIs may be an example of PDCCH messages that can provide UE power savings in paging operations. As described herein, mobility procedures may 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 and inactive mode procedures may be configured within the same downlink BWP or may be distributed across different downlink BWPs. For example, the random access CSS for idle RedCap UEs may be configured in a RedCap-specific initial downlink BWP, while the random access CSS for inactive RedCap UEs may be configured within CORESET#0. Additionally or alternatively, the CSS sets for system information acquisition or paging reception by idle or inactive UEs may be configured within CORESET#0.
[0165] MIB configuration CORESET#0 (e.g., P CORESET0 , S CORESET0 ) and a separate initial downlink BWP (e.g., P RedCap , S RedCap The total number of CORESETs and SS sets configured in the downlink BWP of a non-RedCap UE may be upper 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 a non-RedCap UE. Specifically, the total number of CORESETs and separate initial downlink BWPs in CORESET#0 is determined by the inequality P CORESET0 +P RedCap ≦P0 (for example, P0≦3), and the total number of SS sets and distinct initial downlink BWPs in CORESET#0 is determined according to the inequality S CORESET0 +S RedCap ≦S0 (for example, S0≦10).
[0166] The control channel element (CCE) aggregation level (AL) and the amount of blind decoding candidates for the SS set configured in the RedCap-specific initial downlink BWP may be explicitly provided to the RedCap UE via system information (e.g., for idle and inactive RedCap UEs) or RRC signaling (e.g., for inactive RedCap UEs). The AL for the CSS set configured in the separate initial downlink BWP may be less than a maximum value (e.g., 4, the minimum AL for the CSS set configured by SIB1 in CORESET#0). Downlink control information (DCI) size alignment for the SS set of CORESET#0 and PDCCH transmission in the separate initial downlink BWP may be enabled or disabled via SIB.
[0167] In the example of FIG. 2, the base station 105-a may transmit one or more control messages 205 to the UE 115-a. The one or more control messages may indicate configurations for a first downlink BWP associated with a first mode of operation of the UE 115-a, a second downlink BWP associated with a second mode of operation of the 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, the base station 105-a may transmit the one or more control messages 205-a to the UE 115-a via the first set of resources within the first downlink BWP. Additionally or alternatively, the base station 105-a may transmit one or more control messages 205-b to the UE 115-a via the second set of resources within the second downlink BWP.
[0168] The base station 105-a may also transmit SSB 210 to the UE 115-a via a first set of resources in a first downlink BWP and a second set of resources in a second downlink BWP. For example, the base station 105-a may transmit CD-SSB 210-a to the UE 115-a via the first set of resources in the first downlink BWP (e.g., while the UE 115-a is in a first mode of operation) and may transmit NCD-SSB 210-b to the UE 115-a via the second set of resources in the second downlink BWP (e.g., while the UE 115-a is in a second mode of operation). For example, when the UE 115-a transitions from the first mode of operation to the second mode of operation, the UE 115-a may perform a BWP switching procedure from the first downlink BWP to the second downlink BWP.
[0169] In some examples, the UE 115-a may receive the PWS notification 215 from the base station 105-a via a second set of resources in a second downlink BWP. Similarly, the UE 115-a may receive the system information update 220 from the base station 105-a via a second set of resources in a second downlink BWP. The base station 105-a may indicate the PWS notification 215 or the system information update 220 via 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, among other examples.
[0170] The wireless communication system 200 may support, among other benefits, greater processing efficiency and reduced power consumption in the UE 115-a (e.g., a RedCap UE). For example, the techniques described herein may reduce the number of control resources (e.g., CORESET, SS) that the UE 115-a is configured to monitor while operating in an idle or inactive mode, which may reduce processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by the UE 115-a. Specifically, the described techniques may reduce the number of blind decoding operations performed by the UE 115-a, which may enable the UE 115-a to perform idle or inactive mode operation with greater processing efficiency and reduced power consumption (e.g., using fewer processing resources).
[0171] 3A and 3B illustrate example resource diagrams 300 and 301 supporting downlink control channel monitoring in multiple downlink BWPs in accordance with aspects of the present disclosure. Resource diagrams 300 and 301 may implement or be implemented by aspects of wireless communication system 100 or wireless communication system 200. For example, resource diagrams 300 and 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 diagrams 300 and 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 the network entity.
[0172] Resource diagrams 300 and 301 may support system information updates and PWS notifications for idle and inactive RedCap UEs. For idle or inactive RedCap UEs performing a random access procedure in a separate initial downlink BWP, if a paging CSS is not configured in 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 a paging CSS is configured in the separate initial downlink BWP for idle and inactive RedCap UEs, the PWS notification and system information update for the RedCap UE may 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 may be delivered in the separate initial downlink BWP via a downlink small data transmission triggered by paging. PWS notifications and system information updates can also be delivered via broadcast or multicast PDSCH transmissions scheduled by PDCCH transmissions associated with searchSpaceBroadcast (configured in a separate initial downlink BWP).
[0173] In the example of Figure 3A, an idle RedCap UE may camp on CORESET#0 of the serving cell to receive CD-SSB, system information, paging messages, or a combination thereof. Therefore, an idle RedCap UE can switch to a separate initial downlink BWP to perform random access or to initiate a transition to connected mode. An idle RedCap UE performing random access in a separate initial BWP can refrain from monitoring paging messages in CORESET#0 before establishing an RRC connection with the network entity. System information updates and PWS notifications for RedCap UEs can be delivered via scheduled msg4 or msgB transmissions in the RedCap-specific initial downlink BWP.
[0174] An 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 system information acquisition and system information update procedures. For example, the idle RedCap UE may receive SIB1 or OSI from a network entity via one or more CORESETs and CSSs 315. In some examples, the idle RedCap UE may perform 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. 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. An indication of a system information update or PWS notification may be delivered to the idle or inactive RedCap UE via a paging message or short message. Additionally or alternatively, the system information update and PWS notification can be delivered to the idle or inactive RedCap UE via a downlink small data transmission triggered by the paging message. The idle or inactive RedCap UE may also receive the system information update and PWS notification via one or more broadcast, multicast, PDCCH, or PDSCH transmissions associated with searchSpaceBroadcast, which may be configured in a separate initial downlink BWP.
[0176] An idle or inactive 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 and system information update procedures. For example, the idle or inactive RedCap UE may receive SIB1 or OSI from a network entity via one or more CORESETs and CSSs 355. In some examples, the idle or inactive RedCap UE may perform 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. The idle or inactive RedCap UE may be configured to monitor the 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 services (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 may support, among other benefits, greater processing efficiency and reduced power consumption in a RedCap UE. For example, the techniques described herein may reduce the number of control resources (e.g., CORESETs, SSs) that a RedCap UE is configured to monitor while operating in an idle or inactive mode, which may reduce processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by the RedCap UE. Specifically, the described techniques may reduce the number of blind decoding operations performed by the RedCap UE, which may enable the RedCap UE to perform idle or inactive mode operation with greater processing efficiency (e.g., using fewer processing resources) and reduced power consumption.
[0178] FIG. 4 illustrates an example process flow 400 supporting downlink control channel monitoring in multiple downlink BWPs according to aspects 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, 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, the UE 115-b may receive from the base station 105-b one or more control messages indicating a configuration for a first downlink BWP associated with a first mode of operation of the UE 115-b, a second downlink BWP associated with a second mode of operation of the 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, the UE 115-b may receive an MIB indicating the configuration for the first downlink BWP and the first set of control resources. Similarly, the UE 115-b may receive an SIB, a dedicated RRC message, a multicast message, or a broadcast message indicating the 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 the UE 115-b or the operating mode of the UE 115-b. In some examples, both the first operating mode of the UE 115-b and the second operating mode of the UE 115-b may correspond to the same RRC state. For example, the first operating mode of the UE 115-b and the second operating mode of the UE 115-b may correspond to an RRC idle state (RRC_IDLE) or an RRC inactive state (RRC_INACTIVE) of the UE 115-b. In such an example, the first set of control resources in the first downlink BWP and the second set of control resources in the second downlink BWP may include CSSs and may exclude other SSs. In another example, the first operating mode of the UE 115-b and the second operating mode of the UE 115-b may correspond to an RRC inactive state (RRC_INACTIVE) or an RRC connected state (RRC_CONNECTED) of the UE 115-b. In such an example, the first set of control resources in the first downlink BWP and the second set of control resources in the second downlink BWP may include a CSS, a USS, or both.
[0181] The 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 a bandwidth, an initial PRB location, a numerology, or a combination thereof associated with the first downlink BWP, and the second set of parameters may include a bandwidth, an initial PRB location, a numerology, or a combination thereof associated with the second downlink BWP. In some examples, the first set of parameters may differ from the second set of parameters. Additionally or alternatively, the one or more control messages may indicate a quantity of PRBs in the second downlink BWP, which may be based on a CCE AL of a CORESET in the second downlink BWP, a duration of a CORESET in the second downlink BWP, a total quantity of CORESETs in the second downlink BWP, an RRC state of UE 115-b, or a combination thereof. The one or more control messages may also include a system information message, an RRC message, a broadcast message, or a multicast message indicating a 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, the UE 115-b may determine an amount of control resources (e.g., CORESET, SS) in a second downlink BWP based on the amount of control resources in the first downlink BWP, the sum of the control resources in different downlink BWPs of the UE 115-b, and a threshold amount of control resources related to the capabilities of the 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 an RRC idle state or an 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 an RRC idle state or an 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 an RRC idle state or an RRC inactive state.
[0183] At 415, the UE 115-b may monitor a first set of control resources in a first downlink BWP while the UE 115-b is in a first mode of operation. The UE 115-b may monitor the first set of control resources according to a configuration and based on the capabilities of the UE 115-b. In some examples, the UE 115-b may use the CORESET and SS in the first downlink BWP to perform one or more procedures associated with the first mode of operation of the UE 115-b. For example, the UE 115-b may use the first set of control resources in the first downlink BWP to perform 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, the UE 115-b may receive one or more messages from the base station 105-b via a first set of control resources in the first downlink BWP. For example, the 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 in the second downlink BWP based on the capabilities of the UE 115-b. Additionally or alternatively, the UE 115-b may receive (during the first mode of operation) a CD-SSB, a system information message, a paging message, a PEI message, a random access message, or a combination thereof from the base station 105-b via the first set of control resources in the first downlink BWP associated with the first mode of operation of the UE 115-b. The UE 115-b may also receive an SIB indicating a first DCI size alignment for PDCCH messages in the SS of the first downlink BWP, a second DCI size alignment for PDCCH messages in the SS of the second downlink BWP, or both.
[0185] At 425, the UE 115-b may perform a BWP switching procedure from the first downlink BWP to the second BWP based on transitioning from the first mode of operation to the second mode of operation. At 430, the UE 115-b may monitor a second set of control resources in the second downlink BWP while the UE 115-b is in the second mode of operation. The UE 115-b may monitor the second set of control resources according to the configuration and based on the capabilities of the UE 115-b. In some examples, the UE 115-b may use the CORESET and SS in the second downlink BWP to perform one or more procedures associated with the second mode of operation of the UE 115-b. For example, the UE 115-b may perform 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 using the second set of control resources in the second downlink BWP.
[0186] At 435, the UE 115-b may receive one or more messages from the base station 105-b via the second set of control resources in the second downlink BWP. For example, the UE 115-b may receive one or more of a random access message, a system information message, a multicast message, a broadcast message, a paging message, an SDT (e.g., uplink or downlink), or an NCD-SSB from the base station 105-b via the second set of control resources in the second downlink BWP. As described with reference to FIG. 5, the UE 115-b may also receive a system information update or a PWS notification from the base station 105-b via the second set of control resources in the second downlink BWP.
[0187] Process flow 400 may support greater processing efficiency and reduced power consumption in UE 115-b (e.g., a RedCap UE), among other benefits. For example, the techniques described herein may reduce the number of control resources (e.g., CORESET, SS) that UE 115-b is configured to monitor while operating in an idle or inactive mode, which may reduce processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by UE 115-b. Specifically, the described techniques 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 operation with greater processing efficiency and reduced power consumption (e.g., using fewer processing resources).
[0188] FIG. 5 illustrates an example process flow 500 supporting downlink control channel monitoring in multiple downlink BWPs according to aspects of the present disclosure. Process flow 500 may implement or be implemented by aspects of wireless communication system 100 or wireless communication system 200. For example, process flow 500 may include base station 105-c (e.g., a network entity) and UE 115-c (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 500, operations between UE 115-c and base station 105-c 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 500, and other operations may be added to process flow 500. In the example of FIG. 5, UE 115-c may receive a system information update or PWS notification from base station 105-c via resources in a downlink BWP configured for idle or inactive RedCap UEs.
[0189] At 505, the UE 115-c may receive one or more control messages from the base station 105-c. The one or more control messages may indicate configurations for a first downlink BWP associated with a first mode of operation of the UE, a second downlink BWP associated with a second mode of operation 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 configurations may correspond to the capabilities of the UE 115-c. At 510, the UE 115-c may monitor the first set of resources in the first downlink BWP while the UE 115-c is in the first mode of operation. The UE 115-c may monitor the first set of resources in accordance with the configuration (indicated by the one or more control messages) and based on the capabilities of the UE 115-c. At 515, the UE 115-c may receive one or more messages from the base station 105-c via the first set of resources in the first downlink BWP. The UE 115-c may receive one or more messages according to the configuration and based on the capabilities of the UE 115-c.
[0190] At 520, the UE 115-c may perform a BWP switching procedure from the first downlink BWP to the second downlink BWP based on transitioning from the first mode of operation to the second mode of operation. In some examples, the first mode of operation and the second mode of operation may correspond to the same RRC state. For example, the first mode of operation and the second mode of operation may correspond to an RRC idle state (e.g., RRC_IDLE) or an RRC inactive state (RRC_INACTIVE). In other words, the UE 115-c may transition between different modes of operation while remaining in the same RRC state. These different modes of operation may be associated with different downlink BWPs. At 525, the UE 115-c may monitor a second set of resources in the second downlink BWP (e.g., while the UE 115-c is in the second mode of operation). The UE 115-c may monitor the second set of resources in the second downlink BWP according to a configuration and based on the capabilities of the UE 115-c.
[0191] In some examples, the UE 115-c may perform a random access procedure with the base station 105-c at 530 (while in the second mode of operation). The UE 115-c may perform the random access procedure via a second set of resources in the second downlink BWP. At 535, the UE 115-c may receive a system information update from the base station 105-c via the second set of resources in the second downlink BWP. At 540, the UE 115-c may receive a PWS notification from the base station 105-c via the second set of resources in the second downlink BWP. In some examples, the UE 115-c may receive the system information update or the PWS notification via a random access message (e.g., msgB or msg4) that the base station 105-c may send during the random access procedure (e.g., via the second set of resources in the second downlink BWP).
[0192] For example, the base station 105-c may transmit a system information update or a PWS notification via a random access message if the second downlink BWP does not include a CSS configured for paging operations. If the second downlink BWP includes a CSS configured for paging operations, the base station 105-c may indicate a system information update or a PWS notification via a paging message. In another example, 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 transmit a paging message (e.g., via a second set of resources in the second downlink BWP) that schedules a downlink SDT from the base station 105-c. The base station 105-c may transmit a downlink SDT according to the paging message and may include a system information update or a PWS notification in the downlink SDT. Similarly, the base station 105-c may transmit a PDCCH message (e.g., via a second set of resources in the second downlink BWP) that schedules a broadcast or multicast PDSCH message from the base station 105-c. The base station 105-c may transmit a broadcast or multicast PDSCH message in accordance with the PDCCH message and may include a system information update or a PWS notification in the broadcast or multicast PDSCH message.
[0193] Process flow 500 may support greater processing efficiency and reduced power consumption in UE 115-c (e.g., a RedCap UE), among other benefits. For example, the techniques described herein may reduce the number of control resources (e.g., CORESET, SS) that UE 115-c is configured to monitor while operating in an idle or inactive mode, which may reduce processing costs and power consumption associated with idle or inactive physical downlink control channel (PDCCH) monitoring activities performed by UE 115-c. Specifically, the described techniques may reduce the number of blind decoding operations performed by UE 115-c, which may enable UE 115-c to perform idle or inactive mode operation with greater processing efficiency and reduced power consumption (e.g., using fewer processing resources).
