Techniques for repeating paging early indications.

Abstract

Methods, systems and devices for wireless communications are described. A base station may transmit multiple repetitions of a paging early indication (PEI) signal to a user equipment (UE) to indicate that the UE should receive paging signaling at a paging occasion. The PEI occasions for transmitting the PEI repetitions may have scheduling conflicts. The PEI occasions may collide with other downlink signaling. The UE may implement techniques to resolve scheduling conflicts or collisions of the PEI repetitions. The UE may be configured to receive either the conflicting PEI signaling or the conflicting downlink signaling based on the priority of the signaling. The PEI signaling may be shifted (e.g., delayed) until after the end of the downlink signaling. The UE may be configured with a subset of blind decoding hypotheses for PEI decoding.

Description

[Technical field]

[0001] cross reference This patent application claims the benefit of commonly assigned U.S. patent application Ser. No. 17 / 377,337, filed July 15, 2021, by XU et al., entitled “TECHNIQUES FOR PAGING EARLY INDICATION REPETITION.”

[0002] The following relates to wireless communications, including techniques for repeating paging early indications (PEIs). [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), etc. 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 in some cases be known as user equipment (UE).

[0004] In some systems, a base station may transmit a paging early indication (PEI) to a UE before a paging occasion for the UE to indicate whether the UE will receive a paging message at the paging occasion. In some cases, the base station may transmit multiple repetitions of the PEI to the UE to make it more likely that the UE will decode the PEI. Some techniques for repeating the PEI are inefficient. Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for paging early indication (PEI) repetition. Generally, the described techniques provide for resolving scheduling conflicts or collisions with PEI repetition. A base station may transmit multiple repetitions of a PEI signal to a user equipment (UE) to indicate that the UE should receive paging signaling at a paging occasion. In some cases, a PEI occasion for transmitting a PEI repetition may have a scheduling conflict. For example, a PEI occasion may collide with other downlink signaling, or a PEI occasion may be scheduled in an uplink configured symbol period. The UE may implement techniques to resolve scheduling conflicts or collisions of PEI repetition. For example, the UE may be configured to prioritize receiving PEI signaling or to prioritize receiving downlink signaling. Additionally or alternatively, the PEI occasion for the PEI repetition may be shifted (e.g., delayed) to the first non-conflicting symbol period (e.g., delayed until after the end of the downlink signaling). In some examples, the UE may be indicated the number of PEI repetitions actually transmitted, such as when the number of PEI repetitions actually transmitted differs from the maximum number of PEI repetitions that may be transmitted for one paging occasion. In some cases, the UE may be configured with a subset of blind decoding hypotheses for PEI decoding. For example, the base station may transmit PEI signaling according to a subset of PEI occasions. If the base station does not transmit PEI signaling in one PEI occasion of the subset of PEI occasions, the base station may not transmit PEI signaling in any PEI occasion of the subset of PEI occasions. Additionally or alternatively, the UE may be configured with a PEI window. The base station may transmit PEI signaling at PEI occasions within the PEI window, and the UE may monitor the PEI signaling within the PEI window.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0054] In some wireless communication systems, a user equipment (UE) may operate in a radio resource control (RRC) idle mode or an RRC inactive mode, each of which may be referred to as an inactive state, until the UE has data to transmit or receive (e.g., or another operation to perform over a network connection). The UE may communicate with a network by establishing an RRC connection and transitioning to an RRC connected mode, which may be referred to as an active state. The UE may be configured with a discontinuous reception (DRX) period for paging (e.g., a paging period), which may indicate how often the UE may monitor a paging channel for pages from the network. The UE may monitor paging according to the DRX period while operating in an inactive state to reduce power consumption, and the paging message may indicate whether the UE should transition to an active state to receive data. In some cases, the network may send a paging early indication (PEI) to the UE to indicate whether a subsequent paging occasion includes a scheduled paging message for the UE. For example, a base station may transmit a PEI to indicate whether a UE is to be paged before a paging occasion. Some UEs may be configured into subgroups for PEI signaling, where the PEI transmission indicates a group of UEs to wake up for a paging occasion. PEI techniques may improve power savings in UEs by reducing unnecessary paging physical downlink shared channel (PDSCH) decoding, allowing UEs to skip synchronization signal block (SSB) reception for tracking loop updates for PDSCH decoding, reducing wake-up time when the PEI is located near an SSB, etc.

[0055] In some examples, the base station may transmit repetitions of the PEI in multiple PEI occasions. Transmitting repetitions of the PEI may provide a higher signal-to-noise ratio (SNR), account for different UE implementations, or account for the possibility of Listen-Before-Talk (LBT) failures in unlicensed spectrum. When repetitions of the PEI are configured, some of the repetitions may be scheduled to collide with other signaling. For example, one or more of the repetitions of the PEI may be scheduled simultaneously with other downlink signaling, such as paging physical downlink control channel (PDCCH) signaling, PDCCH signaling for scheduling system information, system information, or SSBs. This may affect reception of the downlink signaling, and the network may attempt to retransmit if the downlink signaling includes critical information, such as SSBs or system information blocks (SIBs).

[0056] The present disclosure provides techniques for PEI repetitions, such as to avoid or resolve scheduling conflicts between the PEI and other scheduled communications. For example, a wireless communication system may implement priorities for PEI signaling and downlink signaling that may collide with the PEI signaling. A UE may be configured with the priorities, and the UE may determine whether to receive PEI signaling or downlink signaling if one or more PEI repetitions collide with downlink signaling. In some examples, if one or more PEI repetitions are scheduled to collide with downlink signaling, the base station may shift the transmission of the PEI repetitions to a first non-colliding symbol. Alternatively, the base station may refrain from transmitting the PEI repetitions in a PEI occasion that is scheduled to collide with downlink signaling or uplink symbol periods, or both.

[0057] In some examples, the network may indicate to the UE the number of PEI repetitions associated with a paging occasion. For example, the network may indicate a maximum number of repetitions for a PEI for a paging occasion via a SIB. However, the network may not transmit the maximum number of PEI repetitions due to scheduling conflicts or resource availability, etc. In some cases, the network may indicate to the UE the number of PEI occasions or transmitted PEI repetitions (e.g., actual transmitted PEI repetitions), or both. Several additional techniques are described herein, such as setting a subset of blind detection hypotheses for PEI repetitions, setting a PEI monitoring window for transmitting PEI repetitions, and PEI signaling monitoring decision, among others.

[0058] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow charts relating to techniques for PEI repetition.

[0059] 1 illustrates an example of a wireless communication system 100 supporting techniques for PEI repetition according to aspects of the 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, a LTE-Advanced (LTE-A) network, a 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 (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0060] The base stations 105 may be distributed throughout a geographic area to form the wireless communication system 100 and may be devices of different configurations 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.

[0061] The UEs 115 may be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may communicate with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) as shown in FIG. 1.

[0062] The base stations 105 may communicate with the core network 130, 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.

[0063] One or more of the base stations 105 described herein may include or be referred to as a base transceiver station, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next generation NodeB or giga-NodeB (any of which may be referred to as a gNB), Home NodeB, Home eNodeB, or other suitable terminology by those skilled in the art.

[0064] 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 any other suitable terminology, and a "device" may also be referred to as a unit, a station, a terminal, or a client, among other 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 other examples, which may be implemented in various articles, such as an appliance, or a vehicle, a meter, among other examples.

[0065] The UEs 115 described herein can communicate 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 other examples.

[0066] The UE 115 and the base station 105 may wirelessly communicate 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 links 125. For example, a carrier used for the communication links 125 may include a portion (e.g., a bandwidth part (BWP)) of a radio frequency spectrum band 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 operations on the carriers, 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.

[0067] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition or control signaling to coordinate operation with respect to 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 over the carrier, or the carrier may operate in a non-standalone mode, where a connection is anchored using a different carrier (e.g., of the same or different radio access technology).

[0068] 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).

[0069] 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 number of carrier bandwidths 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)). The 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 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 a base station 105 or UE 115 that supports 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.

[0070] 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 be composed of one symbol period (e.g., one modulation symbol interval) and one subcarrier, where the symbol period and the subcarrier spacing are inversely proportional. 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 and the higher the order of the modulation scheme that the UE 115 receives, the higher the data rate of the UE 115 may be. 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 the data rate or data integrity of communications with the UE 115.

[0071] One or more numerologies for a carrier may be supported, where 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 of a carrier may be active at a given time, and communication for the UE 115 may be limited to one or more active BWPs.

[0072] 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 may be expressed as a multiple of a base time unit, which may refer to a sampling period of max may represent the maximum supported subcarrier spacing, and N fmay represent the maximum discrete Fourier transform (DFT) size supported. The communication resource time intervals may be organized according to radio frames, each having a specified length (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., in the range of 0 to 1023).

[0073] Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same length. 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 communications systems 100, a slot may be further divided into multiple minislots that include one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The time length of a symbol period may depend on the subcarrier spacing or the frequency band of operation.

[0074] A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI length (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., among a burst of shortened TTIs (sTTIs)).

[0075] The physical channels may be multiplexed on the carriers according to various techniques. The physical control channels and the physical data channels may be multiplexed on the 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 control resource set (CORESET)) for the physical control channels 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., CORESET) 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 search space sets, and each search space set may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidates may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information of the control information format having a given payload size. The search space set may include a common search space set configured for sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0076] 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 (e.g., on a carrier) with the base station 105 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 geographical coverage area 110 or a portion (e.g., a sector) of a geographical 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 others, a building, a subset of a building, or an outside space between or overlapping with the geographical coverage area 110.

[0077] A macro cell generally covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 115 that subscribe to the service of a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 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. A small cell may provide unrestricted access to UEs 115 that subscribe to the service of a 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 a user in a home or office). 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.

[0078] 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.

[0079] In some examples, the base stations 105 may be mobile and therefore provide communication coverage to moving geographic coverage areas 110. In some examples, the different geographic coverage areas 110 associated with different technologies may overlap, but 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.

[0080] The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing and transmissions from different base stations 105 may not be aligned in time, in some examples. The techniques described herein may be used for either synchronous or asynchronous operation.

[0081] 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 allow 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 utilizes such information or presents the information to a human who interacts with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. 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 sensing, physical access control, and transaction-based business billing.

[0082] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports 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 saving techniques for the 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 to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or outside of a carrier.

[0083] 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) or mission-critical communications. The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functionality). Ultra-reliable communications may include private or group communications and may be supported by one or more mission-critical services, such as mission critical push-to-talk (MCPTT), mission critical video (MCVideo), or mission critical data (MCData). Support for mission-critical functionality may include service prioritization, and the mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0084] 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 otherwise 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, where each UE 115 transmits to all other UEs 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.

[0085] In some systems, the D2D communication link 135 may be an example of a communication channel between vehicles (e.g., UE 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, emergency situations, or any other information related to the V2X system. In some examples, the vehicles in the V2X system may communicate with roadside infrastructure, such as roadside units, or with a network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communication, or both.

[0086] 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 (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 (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 as well as other functions. The user plane entity may be connected to one or more network operators' IP services 150. The IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0087] 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).

[0088] The wireless communication system 100 may operate using one or more frequency bands, typically within the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The 300 MHz to 3 GHz region is commonly referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter in length. Although UHF waves may be blocked or redirected by buildings and environmental features, the waves may penetrate structures well enough for a macrocell to provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0089] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed 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 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 a component carrier operating in a licensed band (e.g., LAA). Operation in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0090] The base station 105 or UE 115 may be equipped with multiple antennas that may 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 UE 115 may be located in one or more antenna arrays or antenna panels that may support MIMO operations 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 may use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support radio frequency beamforming of signals transmitted through the antenna ports.

[0091] A base station 105 or a UE 115 can use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. Multiple signals may be transmitted by a transmitting device, for example, via 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 that are used for channel measurements 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.

[0092] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used in 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 device and the receiving device. 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 are subject to constructive interference, while other signals are subject to destructive interference. Adjustment of signals communicated through antenna elements may include a transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals carried through an antenna element associated with the device. The adjustments 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).

[0093] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform a beamforming operation for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times in different directions by the base station 105. For example, the base station 105 may transmit signals according to different beamforming weight sets associated with different directions of transmission. The transmissions in different beam directions may be used (e.g., by a transmitting device such as the base station 105 or by a receiving device such as the UE 115) to identify beam directions for subsequent transmission or reception by the base station 105.

[0094] Some signals, such as data signals associated with a particular receiving device, may be transmitted by the base station 105 in a single beam direction (e.g., a direction associated with a receiving device, such as the UE 115). In some examples, a beam direction associated with a transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, the UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and may report to the base station 105 an indication of the signal that the UE 115 received with the highest signal quality or possibly an acceptable signal quality.

[0095] In some examples, transmission by a device (e.g., by the base station 105 or the UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to the number of configured beams across the system bandwidth or one or more subbands. The base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may be precoded or not. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by the base station 105 in one or more directions, the UE 115 may employ similar techniques to transmit a signal multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by the UE 115) or to transmit a signal in a single direction (e.g., to transmit data to a receiving device).

[0096] A receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals, such as synchronization signals, reference signals, beam selection signals, or other control signals, from the base station 105. For example, the receiving device may attempt multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of the antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" with different receive configurations or receive directions. In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned to a beam direction determined based on listening with different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening with multiple beam directions).

[0097] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communication 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 to communicate on logical channels. The Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (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, the transport channels may be mapped to physical channels.

[0098] 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 is correctly received on 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 in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0099] In some wireless communication systems, the UE 115 may operate in an RRC idle mode or an RRC inactive mode, which may be referred to as an inactive state or a sleep state, respectively, until the UE 115 has data to transmit or receive (e.g., or another operation to perform over a network connection). The UE 115 may communicate with the network by establishing an RRC connection and transitioning to an RRC connected mode, which may be referred to as an active state. The UE 115 may be configured with a DRX period for paging (e.g., a paging period), which may indicate how often the UE 115 may monitor a paging channel for pages from the network. The UE 115 may monitor paging according to the DRX period while operating in the inactive state to reduce power consumption, and the paging message may indicate whether the UE 115 should transition to an active state to receive data.

[0100] In some cases, the network may transmit a PEI to the UE 115 to indicate whether a subsequent paging occasion includes a scheduled paging message for the UE 115. For example, the base station 105 may transmit a PEI to indicate whether the UE 115 is to be paged before a paging occasion. Some UEs 115 may be configured into subgroups for PEI signaling, where the PEI transmission indicates a group of UEs 115 to wake up for a paging occasion. The PEI technique may improve power savings in the UE 115 by reducing unnecessary paging PDSCH decoding, allowing the UE 115 to skip SSB reception for tracking loop updates for PDSCH decoding, reducing wake-up time when the PEI is located close to the SSB, etc.

[0101] In some examples, the base station 105 may transmit repetitions of the PEI in multiple PEI occasions. Transmitting repetitions of the PEI may provide a higher SNR, account for different UE implementations, or account for the possibility of LBT failure in unlicensed spectrum. When repetitions of the PEI are configured, some of the repetitions may be scheduled to collide with other signaling. For example, one or more of the repetitions of the PEI may be scheduled simultaneously with other downlink signaling, such as paging PDCCH signaling, PDCCH signaling for scheduling system information, system information, or SSB. This may affect reception of the downlink signaling, and the network may attempt to retransmit if the downlink signaling includes critical information, such as SSB or SIB.

[0102] In some cases, the PEI may be implemented using UE grouping to provide more efficient power savings. For example, the UEs 115 may be included in a subgroup of UEs 115 that receive the same PEI. The base station 105 may transmit the PEI for the subgroup of UEs 115 to indicate data for one or more UEs 115 in the subgroup.

[0103] In some cases, repetition of the PEI may provide a higher SNR. For example, the cell size of the base station 105 may be large and the base station 105 may serve the UE 115 with limited coverage or capability (e.g., a reduced capability UE 115). A higher SNR, or SNR boosting, may enable the UE 115 to receive the PEI and perform efficient wake-up for paging occasions.

[0104] In some cases, repetitions of the PEI may be transmitted at multiple occasions or multiple locations to account for different UE implementations and SNR conditions. Different UEs 115 may process different amounts of SSBs to perform tracking loop updates. For example, a first UE 115 may process one SSB to perform tracking loop updates, while another UE 115 may process two or more SSBs to perform tracking loop updates. Providing different instances and locations of the PEI within the time-frequency resources may enable different UEs 115 to process different amounts of SSBs. For example, decoding an earlier PEI may enable the first UE 115 to determine whether it should process multiple SSBs, and decoding a later PEI may enable the second UE 115 to remain in a lower power state for a longer period of time.

[0105] In some cases, the repetition of the PEI may be performed in shared or unlicensed radio frequency spectrum bands. Transmitting the repetition of the PEI may increase the likelihood of successful PEI transmission and reception in the event of an LBT failure in these radio frequency spectrum bands.

[0106] When PEI repetition is configured, some transmissions of the PEI may collide with other channels or signals. For example, some PEI repetitions may collide with other downlink signals (e.g., legacy downlink channels and signals), or some PEI repetitions may be scheduled in uplink-bound symbol periods within a slot. In some cases, if a downlink channel or signal includes important information (e.g., SSB or SIB), the network may transmit the downlink channel or signal, which may cause delays in data communication at the UE 115. Among the wireless communication systems described herein, the wireless communication system 100 may implement techniques for resolving scheduling conflicts of PEI repetitions.

[0107] For example, the UE 115 may be configured to prioritize receiving PEI signaling or to prioritize receiving downlink signaling. Additionally or alternatively, the PEI occasion for PEI repetition may be shifted (e.g., delayed) to the first non-conflicting symbol period (e.g., delayed until after the end of downlink signaling). In some examples, the UE 115 may be instructed on the number of PEI repetitions actually transmitted, such as when the number of PEI repetitions actually transmitted is different from the maximum number of PEI repetitions that may be transmitted in one paging occasion. In some cases, the UE 115 may be configured with a subset of blind decoding hypotheses for PEI decoding. For example, the base station 105 may transmit PEI signaling according to the subset of PEI occasions. If the base station 105 does not transmit PEI signaling on one PEI occasion of the subset of PEI occasions, then the base station 105 may not transmit PEI signaling on any PEI occasion of the subset of PEI occasions. Additionally or alternatively, the UE 115 may be configured with a PEI window. The base station may transmit PEI signaling on PEI occasions within the PEI window, and the UE 115 may monitor PEI signaling within the PEI window.

[0108] 2 illustrates an example of a wireless communication system 200 supporting techniques for PEI repetition in accordance with aspects of the present disclosure. The wireless communication system 200 may include a UE 115-a and a base station 105-a, which may be examples of the UE 115 and base station 105, respectively, described with reference to FIG.

[0109] In some cases, to reduce power usage, the UE 115-a may operate in an RRC inactive mode or an RRC idle mode until the UE 115-a is scheduled for data transmission. When the base station 105-a has data for the UE 115-a, the base station 105-a may send a paging message to the UE 115-a, and the UE 115-a can switch from the inactive mode to an active mode, such as an RRC connected mode. The UE 115-a may monitor for paging messages during paging occasions 215 according to the configured DRX period of the UE 115-a.

[0110] In some cases, the base station 105-a may transmit a PEI 205 before a paging occasion to indicate whether the UE 115-a will be paged or not. For example, if the UE 115-a receives a PEI 205 before a paging occasion 215, the UE 115-a may wake up and perform PDSCH decoding during the paging occasion 215. If the UE 115-a does not receive a PEI 205 before a paging occasion 215, the UE 115-a may remain in a sleep mode and skip performing PDSCH decoding during the paging occasion 215.

[0111] The wireless communication system 200 may support techniques for PEI repetition. For example, the base station 105-a may transmit a set 210 of multiple repetitions or instances of a PEI 205. The PEIs 205 in the set 210 may be transmitted in PEI occasions in which the PEIs 205 may be transmitted by the base station 105-a. The PEI occasions may be configured in multiple different occasions prior to a paging occasion 215. In some cases, each PEI 205 in the set 210 may be a repetition of the same PEI, such as a PEI associated with a group or subgroup of UEs 115. In some cases, the base station 105-a may transmit an indication of the PEI configuration to the UE 115-a, such as via system information or RRC signaling. The PEI configuration may indicate, for example, a PEI occasion configuration, a UE subgroup configuration, or the like.

[0112] Upon detecting the PEI 205 from the set 210, the UE 115-a may monitor downlink signaling and process the downlink signaling to obtain an updated tracking loop for decoding a paging message in the paging occasion 215. For example, the UE 115-a may process one or more SSBs 220, or a reference signal such as a CSI-RS or a tracking reference signal (TRS), or a combination thereof. In some cases, the UE 115-a may perform a tracking loop update based on the SSBs 220.

[0113] In some cases, one or more repetitions of a PEI 205 in the set 210 may be scheduled to conflict with other signaling. For example, two PEIs 205 of the set 210 may be scheduled to overlap or conflict with downlink signaling 225. In some other examples, a PEI 205 may be scheduled within an uplink symbol of a slot. Thus, the UE 115-a or base station 105-a, or both, may identify a scheduling conflict or collision 230 of one or more PEIs 205.

[0114] In one example, the downlink signaling 225 may be an example of an SSB 220 or an SIB. The downlink signaling 225 may be transmitted on a downlink channel, such as a PDCCH or a PDSCH. In some cases, the downlink signaling 225 may include or be an example of a paging PDCCH, a scheduling PDCCH for an SIB, an SSB, a SIB PDSCH, a TRS for an idle or inactive mode UE 115, or any combination thereof. If the PEI 205 collides with an urgent or important downlink signaling, the base station 105-a may retransmit the downlink signaling 225. This may delay reception of the downlink signaling 225 including urgent or important information for some devices in the wireless communication system 200.

[0115] The wireless communication system 200, and the wireless communication systems described herein, may support techniques for repeating the PEI. For example, devices of the wireless communication system 200 may implement techniques to avoid or resolve scheduling conflicts, transmission conflicts, or collisions, such as collision 230.

[0116] In one example, the wireless communication system may support techniques for defining or setting priorities between PEI signaling and downlink transmissions or downlink channels, such as the PEI 205 and the downlink signaling 225. The UE 115-a may determine whether to receive the PEI 205 or the downlink signaling 225 according to one or more priorities of the PEI 205 and the downlink signaling 225. In some cases, different types of signaling may have different priorities. For example, the paging PDCCH, the scheduling PDCCH for SIBs, SSBs, SIB PDSCH, and the TRS for idle mode or inactive mode UEs 115 may each be set with a priority. For example, the UE 115-a may, in some examples, be configured to receive the PEI 205 in preference to the SSB 220 in accordance with a priority set for the SSB 220, or the UE 115-a may be configured to receive the TRS in preference to the PEI 205 in accordance with a priority set for the TRS.

[0117] In some cases, PEI transmission priority may be set per channel, broadcast channel, or signal. For example, PEI scheduling (e.g., according to techniques described herein) or PEI transmission priority may be set differently for collisions with TRS than for collisions with PDSCH. In one example, the set 210 of PEIs 205 may be shifted for collisions with TRS (e.g., as described in more detail with reference to FIG. 3), where a portion of the set 210 of PEIs 205 may not be transmitted if the set 210 overlaps with PDSCH. This is one possible example of different scheduling techniques for different types of scheduling conflicts or conflicts, and other scheduling techniques may be applied or set for these and other types of scheduling conflicts or conflicts.

[0118] In another example, the UE 115-a may identify a scheduling conflict. For example, the UE 115-a may identify the collision 230 before the collision 230 occurs. For example, the collision 230 may be between a repeating PEI 205 and a broadcast channel or signal. The UE 115-a may know or be configured with the periodicity or scheduling of the broadcast channel or signal, and the UE 115-a may determine that one or more PEI occasions are scheduled to collide with the broadcast channel or signal. Additionally or alternatively, the base station 105-a may send an explicit indication of the collision 230 to the UE 115-a. In some cases, if the UE 115-a is aware of the scheduling conflict, the UE 115-a may detect a PEI 205 in one or more remaining PEI occasions of the set 210 where the collision 230 does not occur. For example, if the downlink signaling 225 collides with the first two of the four PEIs 205 in the set 210, the UE 115-a may monitor the PEIs 205 in the last two PEI occasions in the set 210 that do not collide with the downlink signaling 225.

[0119] In some examples, the base station 105-a may refrain from transmitting a PEI in a conflicting symbol. For example, if the downlink signaling 225 conflicts with the first two PEI occasions of the set 210, the base station 105-a may not transmit a PEI in the first two PEI occasions. The base station 105-a may still transmit the last two PEIs 205 of the set 210 in two non-conflicting PEI occasions.

[0120] In some cases, the base station 105-a may indicate the number of PEI occasions associated with the paging occasion 215 or associated with the set of PEI repetitions 210. For example, the UE 115-a may receive a PEI configuration that indicates a maximum number of repetitions of the PEI 205 associated with the paging occasion 215. In some cases, the base station 105-a may transmit an indication of the maximum number of repetitions of the PEI 205 associated with the paging occasion 215 via system information, such as in a SIB. For example, the base station 105-a may be allowed to transmit up to four repetitions of the PEI 205 in the set of PEI occasions 210 prior to the paging occasion 215.

[0121] In some cases, the actual number of transmitted PEI repetitions and transmission occasions of the PEI for a paging occasion 215 may differ from the configured maximum number of repetitions. For example, due to a scheduling conflict such as collision 230, base station 105-a may not transmit a PEI 205 in each PEI occasion of set 210 of PEI occasions.

[0122] The UE 115-a may determine the number of PEI repetitions and the number of PEI occasions actually transmitted for the paging occasion 215. In some cases, the base station 105-a may transmit an indication of the number of PEI repetitions and the number of PEI occasions actually transmitted. For example, the base station 105-a may indicate the number of actual PEI transmissions via system information, such as in a SIB. Additionally or alternatively, a previous PEI or paging PDCCH signal may indicate the number of PEI repetitions or the PEI repetition pattern. For example, paging PDCCH signaling in a previous paging occasion may indicate the number of PEI repetitions actually transmitted for the paging occasion 215. In some cases, the number of PEI repetitions or the PEI repetition pattern may be indicated to a UE subgroup. In some cases, the PEI repetition pattern may be an example of a blind detection hypothesis pattern or a subset of repetitions pattern, as described in more detail with reference to FIG. 4.

[0123] In some cases, the UE 115-a may determine the number of repetitions of the PEI and the number of PEI occasions actually transmitted based on the UE blind detection. For example, the UE 115-a may be configured with a blind detection pattern to reduce the processing load at the UE 115-a for detecting the PEI 205. The UE 115-a may perform blind detection on PEI occasions of the set of PEI occasions 210. The UE 115-a may be configured with multiple different patterns of PEI occasions, where the PEI may be transmitted on one or more PEI occasions of the different patterns. For example, the PEI occasions may be configured on several positions or resources for the different patterns. For example, if the UE 115-a detects the PEI 205 on a PEI occasion corresponding to a first pattern, the UE 115-a may determine that the PEI was transmitted on a PEI occasion according to the first pattern. If the UE 115-a does not detect the PEI 205 in the PEI occasions corresponding to the first pattern, the UE 115-a may determine that the PEI 205 is not transmitted in any of the PEI occasions corresponding to the first pattern. An example of this technique may be described in more detail with reference to FIG. 4. In some cases, the number of PEI repetitions and the number of PEI occasions actually transmitted may be based on the blind detection capabilities of the UE 115-a. Additionally or alternatively, the number of PEI repetitions and the number of PEI occasions actually transmitted may be based on the capabilities of another UE 115 in the same subgroup as the UE 115-a.

[0124] In some cases, a transmission conflict may be unknown to the UE 115-a. For example, a scheduling conflict may be based on a collision 230 between one or more PEI transmissions and downlink signaling 225 carrying a UE-specific PDCCH or PDSCH for the UE 115 in connected mode. In addition, a scheduling conflict may arise from a failure of the UE 115-a or the base station 105-a, or both, to gain access to the channel medium when performing an LBT procedure (e.g., an LBT failure).

[0125] For example, the UE 115-a may not be aware of a scheduling conflict and the UE 115-a may not detect the PEI 205 in the selected occasion due to a scheduling conflict (e.g., in the first PEI occasion or the second PEI occasion of the set of PEI occasions 210). In some examples, if the UE 115-a does not detect the PEI 205 in the selected PEI occasion, the UE 115-a may not process any remaining PEI occasions. For example, the UE 115-a may refrain from processing or performing detection in the third or fourth PEI occasion of the set of PEI occasions 210. In some other examples, the UE 115-a may continue to process the remaining PEI occasions until the PEI 205 is detected or all PEI occasions associated with the set of PEI occasions 210 or the paging occasions 215 have been detected.

[0126] In some examples, the UE 115-a may be configured with multiple repeated segments or chunks of a PEI occasion. For example, the UE 115-a may be configured with multiple repeated segments to increase the likelihood of PEI detection while operating in an unlicensed radio frequency spectrum band. Each segment may include one or more PEI occasions, where one occasion has one repetition of the PEI 205 when transmitted. If the UE 115-a does not detect the PEI 205 in one segment, the UE 115-a may continue to perform PEI detection in the remaining segments as long as the UE 115-a has multiple (e.g., two or more) remaining segments scheduled. The UE 115-a may cease PEI detection when the UE 115-a has one remaining segment or after the UE 115-a detects the PEI 205 in one of the segments. In some examples, the base station 105-a may include an indicator (e.g., a one-bit indicator) in the PEI 205 or in the paging PDCCH signaling to instruct the UE 115-a to refrain from monitoring the PEI occasion for paging in the paging occasion 215. In some examples, one or more of these techniques may be implemented by the UE 115 on or across a beam tracked by the UE 115.

[0127] 3 illustrates an example of a PEI occasion shift configuration 300 that supports techniques for PEI repetition according to aspects of the disclosure. The PEI occasion shift configuration 300 may be implemented by a UE 115 or a base station 105, or both, configured for the PEI repetition techniques described herein.

[0128] The base station 105 may transmit multiple repetitions of the PEI 305 to indicate that the UE 115 or group of UEs 115 are configured for paging messages in the paging occasion 315. Upon detecting the PEI 305, the UE 115 may process signaling (e.g., one or more SSBs 320, reference signals, or both) to update tracking loops, obtain channel quality information (CQI), or both, and prepare to perform decoding during the paging occasion 315 to receive the paging message.

[0129] Repetitions of the PEI 305 may be transmitted in a set of PEI occasions 310. In some cases, there may be a scheduling conflict in one or more originally scheduled repetitions of the PEI 305. For example, at least a portion of the set of PEI occasions 310 may be scheduled to collide with other signaling or channels, such as downlink signaling 325. In some cases, the scheduling conflict may be based on a collision with other signaling, or the PEI occasions 310 may overlap or be scheduled in an uplink configured symbol period within a slot.

[0130] In some cases, if the set of PEI occasions 310 is scheduled to collide with other signaling, the set of PEI occasions 310 may be shifted (e.g., by shift 330) to the next non-colliding symbol. For example, the set of PEI occasions 310 may include four PEI occasions, and two of the PEI occasions may be scheduled to overlap (e.g., collide) with downlink signaling 325. Instead of transmitting the PEI 305 in the initially configured set of PEI occasions 310, the base station 105 may delay the set of PEI occasions 310 (and, e.g., the transmission of the PEI 305) by shift 330. For example, the set of PEI occasions 310 and the transmission of the PEI 305 may begin the first symbol period (earliest) after the downlink signaling ends.

[0131] In one example, one or more PEI occasions may collide with a UE-specific channel or UE-specific signaling for a UE 115 operating in a connected mode. A UE 115 operating in an inactive or idle mode may not sense or detect signaling for a connected mode UE 115 before a scheduling conflict occurs. Thus, the base station 105 may employ the shift 330 to transmit the PEI 305 in a full set of shifted PEI occasions (e.g., the set of PEI occasions 310 delayed by the shift 330). In some cases, if the UE 115 is scheduled for multiple sets of PEI occasions prior to the paging occasion 315, the base station 105 may individually shift the set of PEI occasions based on the scheduling conflict. For example, as shown, the base station 105 may shift a first set of PEI occasions that conflict with downlink signaling 325, and the base station 105 may not shift another set of PEI occasions that either have no scheduling conflicts or conflicts or have a different type of scheduling conflict.

[0132] As described herein, in some other examples, the base station 105 may instead refrain from transmitting the PEI 305 in a conflicting symbol. In some cases, whether the base station 105 performs a PEI shift or whether the base station 105 does not transmit the PEI 305 may be configured for different types of scheduling conflicts. For example, the base station 105 may shift the set of PEI occasions 310 for some types of scheduling conflicts or downlink signaling, and the base station 105 may refrain from transmitting the PEI in conflicting portions of the set of PEI occasions 310 for other types of scheduling conflicts or other types of downlink signaling. For example, the base station 105 may shift the set of PEI occasions 310 if the set of PEI occasions 310 is scheduled in an uplink symbol period, and the base station 105 may cancel the PEI transmission during the PEI occasion that overlaps with the uplink symbol period.

[0133] 4 illustrates an example of a blind decoding subset configuration 400 that supports techniques for PEI repetition according to aspects of the disclosure. The blind decoding subset configuration 400 may be implemented by a UE 115 or a base station 105, or both, configured for the PEI repetition techniques described herein.

[0134] The base station 105 may transmit multiple repetitions of the PEI 405 to indicate that the UE 115 or group of UEs 115 are configured for paging messages in the paging occasion 415. Upon detecting the PEI 405, the UE 115 may process the signaling (e.g., one or more SSBs 420, reference signals, or both) to obtain a CQI and prepare to perform decoding during the paging occasion 415 to receive the paging message.

[0135] Repetitions of the PEI 405 may be transmitted in a set of PEI occasions 410. In some cases, there may be a scheduling conflict on one or more repetitions of the PEI 405. For example, at least a portion of the set of PEI occasions 410 may be scheduled to collide with other signaling or channels, such as downlink signaling 425. In some cases, the scheduling conflict may be based on a collision with other signaling, or the PEI occasions 410 may overlap or be scheduled during an uplink configured symbol period within a slot.

[0136] In some cases, due to collisions or scheduling conflicts, the base station 105 may transmit fewer repetitions of the PEI than the maximum number of repetitions of the PEI. For example, the base station 105 may transmit a SIB indicating the maximum number of repetitions of the PEI 405 for each paging occasion 415. However, due to a scheduling conflict, the base station 105 may transmit fewer repetitions of the PEI 405 than the maximum number of repetitions. The UE 115 or the base station 105, or both, may implement techniques for determining how many repetitions of the PEI 405 are transmitted for a paging occasion 415 and, in some cases, patterns for performing blind decoding to obtain the PEI 405.

[0137] In some cases, the base station 105 may transmit an indication of the number of PEI repetitions actually transmitted. For example, the base station 105 may transmit a SIB including an indication of the number of PEI repetitions actually transmitted for the paging occasion 415. Additionally or alternatively, the base station 105 may indicate the number of PEI repetitions actually transmitted via PEI signaling or paging PDCCH signaling, or both. Indicating the number of PEI repetitions via PEI signaling or paging PDCCH signaling may indicate the number of PEI repetitions for a group or subgroup of UEs 115 configured to receive common PEI signaling. In some cases, the number of PEI repetitions may be indicated via PEI signaling or paging PDCCH signaling if the base station 105 does not update the number of PEI repetitions frequently (e.g., if the base station 105 expects or schedules a small number of collisions or scheduling conflicts).

[0138] In some examples, the number of repetitions of the PEI actually transmitted may be based on UE blind detection. For example, the UE 115 may be configured with a blind detection pattern to detect the PEI 405. A scheduling conflict, such as a collision between the PEI 405 and downlink signaling 425 (e.g., a UE-specific channel or signal or the UE 115 in connected mode), may generate different patterns, each corresponding to a blind detection hypothesis of the actual transmission of the PEI 405. Configuring the blind detection pattern may reduce the processing load for the UE 115 to detect the PEI 405. For example, configuring the different patterns may limit the total number of hypotheses at the UE 115 to obtain the PEI 405. By reducing the processing load at the UE 115, the UE 115 may more efficiently combine the repetitions of the PEI, such as for SNR boosting.

[0139] In one example, the UE 115 may be configured with a maximum number of PEI repetitions that may be transmitted in a set of PEI occasions 410. In some cases, the UE 115 may also determine the number of actually transmitted PEI repetitions, such as via signaling from the base station 105 or according to the UE blind decoding capabilities. For example, the UE 115 may be configured with a maximum number of PEI repetitions of eight, and the UE 115 may determine that there are four actually transmitted PEI repetitions for this paging occasion 415.

[0140] The UE 115 may also be configured with one or more PEI repetition subsets 430. A PEI repetition subset 430 may correspond to one possible blind detection hypothesis of a PEI 405 in the set of PEI occasions 410. Different patterns of hypotheses or PEI repetition subsets 430 may be configured in the UE 115, such as via SIB signaling, paging signaling, or semi-static signaling to the UE 115.

[0141] The UE 115 may perform blind decoding according to the PEI repetition subset 430. For example, if the UE 115 does not detect a PEI in one PEI occasion of the PEI repetition subset 430, the UE 115 may determine that the base station 105 did not transmit a PEI 405 in that PEI repetition subset 430. The UE 115 may refrain from performing blind decoding in other PEI occasions of that PEI repetition subset 430 and may attempt blind decoding in PEI occasions of another PEI repetition subset 430. Setting the patterns or PEI repetition subset 430 may reduce the number of PEI transmission patterns seen or decoded by the UE 115. This may reduce the processing load at the UE 115 because if the UE 115 can determine that the PEI 405 is not transmitted in the occasions corresponding to the PEI repetition subset 430, the UE 115 may perform fewer blind decoding procedures.

[0142] In one example, the UE 115 may be configured with a PEI repetition subset 430-a and a PEI repetition subset 430-b. The UE 115 may attempt to acquire the PEI 405 in a PEI occasion of the PEI repetition subset 430-a, and the UE 115 may not detect the PEI 405. The UE 115 may determine that the base station 105 did not transmit a PEI in any occasion of the PEI repetition subset 430-a, and the UE 115 may refrain from performing PEI decoding in any other PEI occasion of the PEI repetition subset 430-a. The UE 115 may then attempt to decode the PEI 405 in an occasion of the PEI repetition subset 430-b, and the UE 115 may receive the PEI 405. The UE 115 may determine that the base station 105 transmits a PEI in the PEI repetition subset 430-b. In some cases, the UE 115 may decode the PEI 405 in additional PEI occasions of the PEI repetition subset 430-b, such as for SNR boosting.

[0143] The pattern of the PEI repetition subset 430 may be configurable by the base station 105, may be configured in the wireless communication system, or both. In some cases, the PEI repetitions may be transmitted in consecutive occasions. For example, for PEI repetition subset 430-a and PEI repetition subset 430-b, the PEI 405 may be transmitted in consecutive groups (e.g., without gaps between PEI signaling within the PEI repetition subset 430). Additionally or alternatively, other patterns may be used. For example, PEI repetition subset 430-c and PEI repetition subset 430-d may be configured, where the PEI repetition subset 430 alternate with each other within the set of PEI occasions 410. If the UE 115 does not detect a PEI 405 during a first portion of the PEI repetition subset 430-c, the UE 115 may refrain from performing PEI decoding during a second portion of the PEI repetition subset 430-c. In some cases, the number of transmitted PEI repetitions may be a subset of one to a configured maximum number of repetitions of the paging occasions 415. In other examples or implementations, the UE 115 may be configured with a different number of PEI repetition subsets 430, a different amount of PEI repetitions per PEI repetition subset 430, a different pattern for the PEI occasions of the PEI repetition subset 430, a different maximum number of PEI repetitions for the paging occasions 415, or any combination thereof.

[0144] 5 illustrates an example of a PEI window configuration 500 that supports techniques for PEI repetition according to aspects of the disclosure. The PEI window configuration 500 may be implemented by a UE 115 or a base station 105, or both, configured for the PEI repetition techniques described herein.

[0145] The base station 105 may transmit multiple repetitions of the PEI 505 to indicate that the UE 115 or group of UEs 115 are configured for paging messages in the paging occasion 515. Upon detecting the PEI 505, the UE 115 may process the signaling (e.g., one or more SSBs, reference signals, or both) to obtain a CQI and prepare to perform decoding during the paging occasion 515 to receive the paging message.

[0146] In some cases, the UE 115 may be configured with a PEI monitoring window 510. For example, the base station 105 may configure a PEI monitoring window 510 for the UE 115, a group of UEs 115, or a subgroup of UEs 115 to receive PEI signaling within the PEI monitoring window 510. The PEI monitoring window 510 may provide a boundary for the UE 115 to perform PEI detection. The PEI monitoring window 510 may help the UE 115 detect the PEI 505 by providing a limited set of resources over which the PEI 505 may be transmitted. This may further reduce the processing power consumed by the UE 115 to detect the PEI 505.

[0147] The PEI monitoring window 510 may have a set length. For example, the PEI monitoring window 510 may span a configurable number of symbol periods or slots, or both. In some cases, the PEI monitoring window 510 may be set with respect to a gap 525 or an offset to a paging occasion 515. In some cases, the gap 525 may be set such that the UE 115 may process the PEI 505 before the start of the paging occasion 515. For example, the PEI monitoring window 510 may be set with a length of one slot, and the PEI monitoring window 510 may be set to be offset from the paging occasion 515 (e.g., in the time domain) by the gap 525 of a set number of slots or symbol periods.

[0148] In some cases, the UE 115 may assume that the PEI 505 is transmitted on all PEI occasions within the PEI monitoring window 510. For example, if the UE 115 is to receive paging signaling in the paging occasion 515, the PEI 505 may be transmitted in each PEI occasion within the PEI monitoring window 510. In some cases, the PEI 505 may not be transmitted in a PEI occasion for which a collision or scheduling conflict occurs within the PEI monitoring window 510. For example, the base station 105 may transmit the PEI 505 in each PEI occasion within the PEI monitoring window 510 unless resources for the PEI occasion are occupied or conflict with a higher priority transmission.

[0149] In some cases, the window may not include any configured PEI occasions. For example, there may be a mismatch between the PEI occasion configuration (e.g., occasion and offset) and the configuration of the PEI monitoring window 510, such that the configured PEI occasion is not within the PEI monitoring window 510. In some cases, the UE 115 may then process the paging occasion 515 to detect paging PDCCH signaling. In some other examples, the UE 115 may not process the paging occasion 515, and the UE 115 may refrain from monitoring for paging signaling during the paging occasion 515 if there is a configuration mismatch.

[0150] In some cases, the PEI monitoring window 510 may be configured in the UE 115 via signaling. For example, in some cases, the PEI monitoring window 510 may be configured via system information (e.g., SIB), control signaling, or paging signaling, or any combination thereof. Additionally or alternatively, the PEI monitoring window 510 may be preconfigured in the UE 115 of the wireless communication system. For example, the configuration of the PEI monitoring window 510 may be stored in a memory at the UE 115.

[0151] 6 illustrates an example of a process flow 600 supporting a technique for repeating a PEI according to an aspect of the disclosure. The process flow 600 may be implemented by the UE 115-b or the base station 105-b, or both. The UE 115-b may be an example of a UE 115 as described herein, and the base station 105-b may be an example of a base station 105 as described herein. In some cases, some processes or signaling of the flows of the process flow 600 may be implemented in a different order than the order shown. Additionally or alternatively, some processes or signaling shown in the process flow 600 may not be performed, or additional signaling or procedures may be performed.

[0152] At 605, the UE 115-b may receive signaling indicating a PEI configuration associated with an idle mode or an inactive mode for the UE 115-b. In some cases, the PEI configuration may include an indication of a PEI repetition scheme for the UE 115-b. For example, the PEI configuration may indicate a maximum number of PEI repetitions associated with a paging occasion. Additionally or alternatively, the PEI configuration may include an indication of the number of actually transmitted PEI repetitions of the paging occasion. In some cases, the base station 105-b may transmit an indication of the PEI configuration via control signaling (e.g., RRC signaling), system information (e.g., SIB), paging signaling (e.g., paging PDCCH, PEI signaling), or any combination thereof. In some cases, the PEI configuration may include one or more blind hypothesis patterns. For example, the PEI configuration may indicate a subset of one or more PEI repetitions for the UE 115-b to perform blind decoding.

[0153] In some cases, the PEI configuration may indicate a PEI monitoring window. For example, the UE 115-b may receive signaling indicating a configuration of a PEI window associated with a set of multiple PEI occasions. The PEI window may be separated from the paging occasions by a gap in time. In some cases, the PEI window may have a set length or duration. For example, the PEI window may span a set or configurable number of symbol periods or slots. In some cases, the PEI configuration may indicate the PEI window duration and gap or offset from the paging occasions.

[0154] At 610, the UE 115-b or the base station 105-b, or both, may determine a scheduling conflict in one or more symbols based on a set of PEI occasions being scheduled in at least one or more symbols based on the PEI configuration. In some examples, the UE 115-b may receive an indication of a scheduling conflict. For example, the base station 105-b may send an indication of a scheduling conflict to the UE 115-b via paging signaling (e.g., paging PDCCH signaling, PEI signaling, etc.). Additionally or alternatively, the UE 115-b may determine a scheduling conflict based on a periodicity or scheduling of downlink signaling, PEI signaling, slot format configuration, or any combination thereof.

[0155] For example, the set of PEI occasions may be scheduled to at least partially overlap with downlink signaling from the base station 105-b. The downlink signaling may be UE-specific or dedicated downlink signaling, such as UE-specific PDCCH signaling or UE-specific PDSCH signaling. Additionally or alternatively, the set of PEI occasions may be scheduled to overlap with broadcast channels or signaling, such as paging PDCCH signaling, scheduling PDCCH for SIBs, SSBs, SIBs, PDSCH signaling carrying SIBs, TRS (e.g., for UEs 115 in idle or inactive modes), or any combination thereof. In some examples, the scheduling conflict may be based on one or more PEI occasions of the set of PEI occasions being scheduled during an uplink configuration symbol period.

[0156] At 615, the UE 115-b may monitor at least a portion of the set of PEI occasions based on determining the scheduling conflict. For example, the UE 115-b may monitor PEI signaling in one or more symbols or monitor downlink signaling in one or more symbols based on the PEI configuration. In some cases, the UE 115-b may receive downlink signaling in one or more symbols based on the PEI configuration assigning a higher priority to downlink signaling than PEI signaling. In some cases, the UE 115-b may receive PEI signaling in the remaining portion of the PEI occasions, such as one or more PEI occasions that do not overlap with the downlink signaling.

[0157] In some other examples, the UE 115-b may receive the PEI signaling in one or more symbols based on the PEI configuration assigning a higher priority to the PEI signaling than the downlink signaling. For example, when the PEI signaling conflicts with some type of downlink signaling, the UE 115-b may receive the PEI signaling instead of the downlink signaling based on the PEI signaling having the higher priority.

[0158] In some cases, the base station 105-b may not transmit a PEI in a PEI occasion that has a scheduling conflict. For example, the base station 105-b may refrain from transmitting a PEI in a PEI occasion that overlaps with some type of downlink signaling. Additionally or alternatively, the base station 105-b may refrain from transmitting PEI signaling in an uplink configured symbol period.

[0159] In some cases, the base station 105-b may transmit PEI signaling in a shifted set of PEI occasions based on the scheduling conflict. In some cases, the shifted set of PEI occasions may start in the first symbol period after the scheduling conflict. The UE 115-b may monitor the PEI signaling in the shifted set of PEI occasions based on determining the scheduling conflict. For example, the scheduling conflict may be between one or more PEI occasions and a broadcast channel or broadcast signaling. The UE 115-b may determine the scheduling conflict before the collision, and the UE 115-b may determine that the set of PEI occasions has been shifted (e.g., by shifting). Some examples of this technique are described in more detail with reference to FIG. 3.

[0160] In some examples, the UE 115-b may perform blind decoding on a subset of hypotheses to obtain the PEI signaling. For example, the UE 115-b may be configured with a pattern of PEI occasions. The UE 115-b may perform blind decoding on the PEI occasions according to the subset of PEI occasions.

[0161] For example, the UE 115-b may perform blind decoding on a first PEI occasion corresponding to the first subset of PEI occasions. In some cases, the UE 115-b may ignore the remaining PEI occasions corresponding to the first subset of PEI occasions based on the blind decoding being unsuccessful on the first PEI occasion. For example, if the base station 105-b does not transmit PEI signaling in one PEI occasion of the first subset of PEI occasions, the base station 105-b may not transmit PEI signaling in any PEI occasion of the first subset of PEI occasions. The UE 115-b may perform blind decoding on a second subset of PEI occasions based on, for example, that PEI signaling is not transmitted on the first subset of PEI occasions.

[0162] In another example, the UE 115-b may perform blind decoding on a first PEI occasion corresponding to a first subset of PEI occasions. In some cases, the UE 115-b may detect PEI signaling within a first PEI occasion of the first subset of PEI occasions. In some cases, the UE 115-b may perform PEI detection on additional PEI occasions of the first subset of PEI occasions, such as for SNR boosting. In some examples, the UE 115-b may ignore the remaining subsets of PEI occasions (e.g., in other subsets of PEI occasions) based on detecting PEI signaling during at least a first PEI occasion corresponding to the first subset of PEI occasions.

[0163] In some cases, the UE 115-b may not detect a scheduling conflict until a collision or scheduling conflict occurs. For example, the collision may be unknown to the UE 115-b, and the UE 115-b may not identify a PEI in one or more selected PEI occasions. In some cases, if the UE 115-b does not detect a PEI during a first selected PEI occasion, the UE 115-b may refrain from processing any remaining PEI occasions. In some examples, the UE 115-b may monitor PEI signaling in a set of PEI occasions until a threshold number of PEI occasions have been monitored or until detection of PEI signaling. For example, the UE 115-b may monitor PEI signaling during one or more colliding symbol periods and continue to monitor PEI signaling until the UE 115-b detects a PEI or monitors a threshold number of PEI occasions. The threshold number of PEI occasions may be indicated in paging signaling (eg, PEI signal or paging PDCCH signaling) or may be configured (eg, pre-configured) as part of the PEI configuration.

[0164] In some cases, the base station 105-b may send an instruction for the UE 115-b to stop monitoring the PEI occasions. For example, the UE 115-b may receive an instruction to stop monitoring the remaining portions of the set of PEI occasions via PEI signaling in the PEI occasions or paging signaling in the paging occasions. The UE 115-b may then refrain from monitoring the remaining portions of the set of PEI occasions. In some cases, the UE 115-b may be configured for repeated segments or chunks of PEI occasions, where each segment includes one or more PEI occasions. If the UE 115-b does not detect a PEI within one segment, the UE 115-b may continue to perform PEI detection until the UE 115-b has only a single segment of the PEI occasion remaining. For example, the UE 115-b may monitor PEI signaling in at least a portion of the set of PEI occasions based on being scheduled in a plurality of the PEI sets.

[0165] In some cases, the UE 115-b may monitor PEI signaling within a PEI monitoring window. For example, the UE 115-b may receive signaling (e.g., the signaling at 505) that indicates a configuration of a PEI window associated with a set of multiple PEI occasions, where the PEI window is separated from the paging occasions by a gap in time. The base station 105-b may transmit the PEI to the UE 115-b within the PEI window, which may reduce the processing or monitoring burden for the UE 115-b to detect the PEI signaling. The UE 115-b may determine whether to monitor PEI signaling in one PEI occasion of the set of multiple PEI occasions within the PEI window while operating in an inactive mode or an idle mode based on the configuration.
