Background Art

[0003] The following relates generally to wireless communications, and more particularly to paging configurations in beamforming wireless communications.

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may use techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiplexing (OFDM), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread OFDM (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each of which simultaneously supports the communication of multiple communication devices, which may be referred to as user equipment (UE).

[0005] In some deployments, the wireless communication system may operate in the millimeter wave (mmW) frequency range (e.g., 28 GHz, 40 GHz, 60 GHz, etc.). Wireless communication at these frequencies may be associated with increased signal attenuation (e.g., path loss), which may be affected by various factors, such as temperature, air pressure, diffraction, etc. As a result, signal processing techniques (such as beamforming) may be used to coherently combine energy and overcome path loss at these frequencies. When a UE is monitoring transmissions from a base station, multiple beamformed transmission beams may be monitored for information. Such monitoring may have associated energy consumption and overhead at the UE, and therefore techniques may be desirable that may reduce the amount of time a UE monitors a downlink transmission beam.

[0006] Overview

[0007] The described technology relates to improved methods, systems, devices or equipment (apparatus) for supporting paging configuration in beamforming wireless communications. According to various aspects of the present disclosure, a base station may provide a paging configuration that indicates one or more occasions for a user equipment (UE) to monitor for paging. The location of the paging occasion may be based at least in part on at least one synchronization signal block (SSB) transmitted by the base station. In some cases, a mapping between a paging occasion index and a location of the paging occasion is indicated in the paging configuration. In some cases, a paging window may be configured during a downlink time slot containing an SSB transmission, and the paging transmission may use the same beamforming parameters as the SSB transmission beamforming parameters.

[0008] In some cases, a base station may identify multiple orders of paging occasions based at least in part on a transmission type used to indicate SSB locations to a UE. In some cases, a paging search space used for paging downlink control information (DCI) transmissions may be based on a combined ordering of paging occasions. In some cases, the combined ordering of the paging search space may be based on a first paging occasion order, followed by one or more paging occasions in a second paging occasion order that are not included in the first paging occasion order.

[0053] Detailed Description

[0054] The described technology relates to improved methods, systems, devices, and equipment (devices) for supporting paging configuration in beamformed wireless communications. In some deployments, an idle mode user equipment (UE) may monitor paging transmissions from a base station. In addition, in some cases, a synchronization signal block (SSB) may be transmitted using a beamformed transmission beam that may be monitored by the UE. The paging transmission may be transmitted using beamforming parameters used to transmit the SSB. In some aspects of the present disclosure, a base station may provide a paging configuration that indicates one or more occasions for the UE to monitor paging, wherein the location of the monitored paging occasions may be based at least in part on which beamformed transmission beams the base station uses to transmit the SSB. In some cases, a mapping between a paging occasion index and a location of the paging occasion is indicated in the paging configuration. In some cases, a paging window may be configured during a downlink timeslot containing an SSB transmission.

[0055] In some cases, the explicitly configured location of the first paging physical downlink control channel (PDCCH) monitoring occasion of the paging occasion may be signaled to the UE together with different parameters of the configured paging search space (e.g., MonitoringSlotPeriodicityAndOffset, Duration, and MonitoringSymbolsWithinSlot) to define a non-default association between an SSB and a paging PDCCH monitoring occasion. In addition, in some cases, a one-to-one mapping may be provided between an SSB and a paging PDCCH monitoring occasion. The SSBs may thereby be mapped coherently to different paging PDCCH monitoring occasions. If there are multiple paging PDCCH monitoring occasions within a transmission slot, different SSBs may be mapped to different paging PDCCH monitoring occasions within the slot.

[0056] In some cases, a base station may identify multiple orders of paging occasions based at least in part on a transmission type used to indicate an SSB location to a UE. In some cases, a paging search space for paging downlink control information (DCI) transmissions may be based on a combined ordering of paging occasions. In some cases, the combined ordering of the paging search space may be based on a first paging occasion order, followed by one or more paging occasions in a second paging occasion order that are not included in the first paging occasion order. In some cases, as discussed herein, a UE may serve UE functionality in an integrated access backhaul (IAB) network. Due to the lower overhead and power consumption achieved by transmitting paging transmissions and monitoring paging transmissions only in configured paging occasions, a system employing techniques such as those provided herein may have enhanced efficiency.

[0057] Aspects of the present disclosure are initially described in the context of wireless communication systems. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to paging configurations in beamforming wireless communications.

[0058] Figure 1 An example of a wireless communication system 100 supporting paging configuration in beamforming wireless communication according to various aspects of the present disclosure is illustrated. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, or communications with low-cost and low-complexity devices.

[0059] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 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 Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be able to communicate with various types of base stations 105 and network equipment (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0060] Each base station 105 may be associated with a particular geographic coverage area 110 in which it supports communications with various UEs 115. Each base station 105 may provide communications coverage for the respective geographic coverage area 110 via a communications link 125, and the communications link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communications link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

[0061] The geographic coverage area 110 of the base station 105 may be divided into sectors that constitute only a portion of the geographic coverage area 110, and each sector may be associated with a cellular cell. For example, each base station 105 may provide communication coverage for a macrocellular cell, a small cellular cell, a hotspot, or other types of cellular cells, or various combinations thereof. In some examples, the base station 105 may be mobile and therefore provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, and overlapping geographic coverage areas 110 associated with different technologies may be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0062] The term "cell" refers to a logical communication entity for communicating with base station 105 (e.g., on a carrier), and may be associated with an identifier to distinguish adjacent cells operating via the same or different carriers (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)). In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or others). In some cases, the term "cell" may refer to a portion of a geographic coverage area 110 (e.g., a sector) on which the logical entity operates.

[0063] Each UE 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. UE 115 can also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, wherein "device" can also be referred to as a unit, a station, a terminal, or a client. UE 115 can also be 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, UE 115 can 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, etc., which can be implemented in various items (such as electrical appliances, vehicles, meters, etc.).

[0064] 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 technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay the information to a central server or application, which may utilize the information or present the information to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0065] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving "deep sleep" mode when not engaged in active communications, or operating over a limited bandwidth (e.g., in accordance with narrowband communications). In some cases, UE 115 may be designed to support critical functions (e.g., mission critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communications for these functions.

[0066] In some cases, UE 115 may also be able to communicate directly with other UE 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more UEs in a group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in this 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 for other reasons. In some cases, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0067] The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other over a backhaul link 134 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130).

[0068] 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), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access layer (e.g., control plane) functions such as mobility, authentication, and bearer management of UEs 115 served by base stations 105 associated with the EPC. User IP packets may be delivered through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet switched (PS) streaming services.

[0069] At least some network devices (such as base stations 105) may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with each UE 115 through a number of other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or merged into a single network device (e.g., base station 105).

[0070] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths are in the range of from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features. However, these waves may penetrate various structures sufficiently for macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to transmission using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0071] The wireless communication system 100 may also operate in the very high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as the centimeter frequency band. The SHF region includes frequency bands that may be opportunistically used by devices that can tolerate interference from other users, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band.

[0072] The wireless communication system 100 may also operate in the extremely high frequency (EHF) division of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to 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 antenna of the corresponding device may be even smaller and more closely spaced than the UHF antenna. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency divisions, and the use of frequency bands specified across these frequency divisions may differ by country or regulatory agency.

[0073] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may adopt license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as a 5GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (such as base stations 105 and UE 115) may adopt a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operations in unlicensed bands may be based on CA configurations (e.g., LAA) in coordination with CCs operating in licensed bands. Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum may be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of the two.

[0074] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., the base station 105) and a receiving device (e.g., the UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication may employ multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of these 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. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0075] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or direct an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying a particular amplitude and phase shift to the signal carried via each antenna element associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0076] In one example, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions, which may include a signal being transmitted according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by the base station 105 or a receiving device, such as the UE 115) a beam direction for subsequent transmission and / or reception by the base station 105. 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, the beam direction associated with transmissions along a single beam direction may be determined based at least in part on signals transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report indications of the signals it received with the highest signal quality or other acceptable signal quality to base station 105. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a recipient device).

[0077] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may try multiple receive beams when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may try multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some examples, the receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). A single receive beam may be aligned in a beam direction determined based at least in part on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or other acceptable signal quality based at least in part on listening according to multiple beam directions).

[0078] In some cases, the antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays that may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 may be located at different geographic locations. A base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0079] In some cases, the wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer can be based on IP. In some cases, the radio link control (RLC) layer can perform packet segmentation and reorganization to communicate on the logical channel. The media access control (MAC) layer can perform priority handling and multiplex logical channels into transport channels. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide retransmission of the MAC layer, thereby improving link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer supporting user plane data between the UE 115 and the base station 105 or the core network 130. In the physical (PHY) layer, the transport channel can be mapped to the physical channel.

[0080] In some cases, UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood of correctly receiving data on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput of the MAC layer in poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0081] The time interval in LTE or NR can be represented by a basic time unit (which may refer to a sampling period T, for example). s =1 / 30,720,000 seconds). The time intervals of the communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period may be expressed as T f =307,200Ts . A radio frame may be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1 ms. A subframe may be further divided into 2 time slots, each having a duration of 0.5 ms, and each time slot may contain 6 or 7 modulation codeword periods (e.g., depending on the length of the cyclic prefix added before each codeword period). Excluding the cyclic prefix, each codeword period may contain 2048 sampling periods. In some cases, a subframe may be the minimum scheduling unit of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0082] In some wireless communication systems, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. In some instances, a symbol of a mini-slot or a mini-slot may be the minimum scheduling unit. For example, each symbol may vary in duration depending on the subcarrier spacing or the operating frequency band. Further, some wireless communication systems may implement time slot aggregation, wherein a plurality of time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0083] The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communications on the communication link 125. For example, a carrier of the communication link 125 may include a portion of a radio frequency spectrum band that operates according to a physical layer channel for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an E-UTRA Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or configured to carry downlink communications and uplink communications (e.g., in TDD mode). In some examples, a signal waveform transmitted on a carrier may include multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or DFT-s-OFDM).

[0084] The organization structure of the carrier may be different for different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR, etc.). For example, communications on a carrier may be organized according to TTIs or time slots, each of which may include user data and control information or signaling to support decoding of the user data. A carrier may also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate carrier operations. In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operations of other carriers.

[0085] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some examples, control information transmitted in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0086] 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 "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 may be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 may be configured to operate using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0087] In a system using MCM technology, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate of communication with UE 115.

[0088] According to some examples, the base station 105 may provide a paging configuration that indicates one or more occasions for the UE 115 to monitor for paging. The location of the paging occasion may be based at least in part on the actual location of the SSB transmitted by the base station 105. In some cases, a mapping between a paging occasion index and the location of the paging occasion is indicated in the paging configuration. In some cases, a paging window may be configured during a downlink time slot containing an SSB transmission, and the paging transmission may use the same beamforming parameters as the SSB transmission beamforming parameters. In some cases, the base station 105 may identify multiple orders of paging occasions based at least in part on the transmission type used to indicate the SSB location to the UE 115. In some cases, the paging search space used for paging DCI transmissions may be based on a combined ordering of paging occasions. In some cases, the combined ordering of paging search spaces can be based on a first paging occasion order (e.g., an order determined based on a system information block type 1 (SIB1) transmission), followed by one or more paging occasions in a second paging occasion order (e.g., an order determined based on an RRC transmission) that are not included in the first paging occasion order.

[0089] Figure 2 An example of a wireless communication system 200 that supports paging configuration in beamforming wireless communications according to aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include a base station 105-a and a UE 115-a, which can be examples of corresponding devices described herein.

[0090] In this example, base station 105-a may transmit multiple SSBs to UEs (including UE 115-a) located within the coverage area of ​​base station 105-a. Beam 210 may be used to transmit the SSBs. In addition, each beam 210 may have an associated paging opportunity during which the paging transmission may be quasi co-located (QCL) with the corresponding SSB. UE 115-a may use the associated beam 215 for uplink transmissions, and the beamforming parameters for the associated beam 215 may be used for both uplink transmissions and downlink transmissions. Although Figure 2 The illustration in shows beamforming transmissions between a base station 105 - a and a UE 115 - a , but the techniques provided herein may also be applied to other types of transmissions.

[0091] In some cases, the subframe or downlink time slot position of the paging occasion may be configured by the base station 105-a. In some cases, SSBs may be transmitted in up to 64 SSB directions, but the base station 105-a may actually transmit the SSBs in a subset of the 64 available SSB directions. In such cases, the paging transmission may also be transmitted only in a subset of directions (e.g., in the directions of the transmission beams 210-a, 210-b, 210-c, and 210-d). The configurable subframe or downlink time slot position of the paging position may thereby allow the base station 105-a to configure the gap between two paging occasions that may accommodate the paging sweeps performed by the base station 105-a and the SSBs actually transmitted. In some cases, the base station 105-a may configure the starting position of each paging occasion within the paging frame and provide such configuration to the UE 115-a via, for example, a system information block (SIB). The UE 115 - a may then monitor for paging for each paging occasion according to the starting position of that paging occasion.

[0092] In other cases, the base station 105-a can configure the starting position of the first paging occasion within the paging frame and the duration of the paging beam sweep. After the duration of the paging beam sweep, subsequent paging occasions can be based on the previous paging occasion. In some cases, the paging beam sweep duration can be configured with respect to the number of downlink time slots, and the UE 115-a can convert the indicated duration to the actual duration by taking into account one or more intervening time slots that may invalidate the paging DCI, such as uplink time slots or other time slots (e.g., random access time slots, time slots within the RMSI search space, etc.). In some cases, the base station 105-a can provide paging configuration via remaining minimum system information (RMSI) transmission, other system information (OSI) transmission, radio resource control (RRC) signaling, or any combination thereof. Additionally or alternatively, the paging configuration can be provided via a media access control (MAC) control element (CE), downlink control information (DCI), a switching message, one or more reference signals or reference signal sequences, or a combination thereof.

[0093] As indicated, in some cases, the base station 105-a may indicate to the UE 115-a the configured monitoring occasions for each transmitted SSB. In such cases, the monitoring window within the paging occasion corresponding to the actual transmitted SSB-i may be derived from the following calculation:

[0094] mod((X i_s n+f(i)), the number of time slots per frame in the paging parameter set,

[0095] in:

[0096] n = (paging SCS) / (15kHz);

[0097] X i_s is the starting offset of the paging occasion i_s, where in some cases up to four paging occasions (i_s) may be defined.

[0098] In some cases, for different values ​​of i_s, X i_s Can be pre-configured or fixed (e.g., the configured value can be from the set {0, 1, ..., 9}). In some deployments, a search space for RMSI can be established. In some examples, for the RMSI search space, If N = 2 and X i_s ∈{0,2,5,7}, then M=1 / 2; if N=1 and X i_s ∈{0,2,5,7}, then M=1; if N=1 and X i_s ∈{0,5}, then M=2.

[0099] In some examples, a similar function f(i) may be used for paging space. In some examples, f(i) may indicate an additional offset corresponding to SSB-i, where i is an SSB index ordered by the actual transmitted SSB (e.g., the SSB index of the actual transmitted SSB provided in the system information block (SIB) or RRC signaling). For example, if base station 105-a transmits SSB#0, 1, 3 but not SSB#2; then in the above equation, i corresponding to SSB#3 will take the value of 2. In some cases, N is the number of search space sets per time slot, which may be configured as {1, 2}.

[0100] In other cases, the base station 105-a may indicate to the UE 115-a the configured starting position and duration of the paging beam sweep. In such cases, the monitoring window within the paging occasion corresponding to the actual transmitted SSB-i may be derived from the following calculation:

[0101] mod((X o n+i s *f(d)·n+f(i)), the number of time slots per frame in the paging parameter set)

[0102] in:

[0103] n = (paging SCS) / (15kHz);

[0104] X0 is the starting offset of paging occasion 0, and up to four paging occasions (i_s) can be defined (e.g., i_s = {0, 1, 2, 3});

[0105] d is the paging beam sweep duration (in consecutive downlink time slots);

[0106] f(d) is the actual paging beam sweep duration, accounting for uplink timeslots and other locations where paging DCI may be invalidated;

[0107] In some cases, x0 may be configured or fixed for different i_s values, where the configured value may be from the set {0, 1, ..., 9}.

[0108] Similar to the above discussion, for the RMSI search space, If N = 2 and X i_s ∈{0,2,5,7}, then M=1 / 2; if N=1 and X i_s ∈{0,2,5,7}, then M=l; if N=1 and X i_s ∈{0,5}, then M=2. In some cases, f(i) is an additional offset corresponding to SSB-i, where i is the SSB index sorted by the SSB actually transmitted. For example, if base station 105-a transmits SSB#0, 1, 3 but not SSB#2, then in the above equation, i corresponding to SSB#3 will take the value of 2. N is the number of search space sets per time slot, which can be configured as {1, 2}.

[0109] Therefore, the mapping from the paging occasion index to the paging location can be configurable within the radio frame. In some cases, the signaling of the paging configuration can indicate which technology is being used to identify the location of the paging occasion. In some cases, the association between the actually transmitted SSB and the monitoring window of the PDCCH containing the paging DCI and the broadcast OSI DCI can be configured separately via the RMSI. In addition, the default association between the SSB index and the monitoring window of the PDCCH containing the paging DCI and the broadcast OSI DCI can be the same as the default association between the SSB index and the RMSI monitoring window.

[0110] In some cases, the paging frame (PF) and paging occasion (PO) may be determined as follows to derive the "first reference point":

[0111] (SFN mod T) = (T div N) * (UE_ID mod N), where

[0112] SFN: system frame number;

[0113] T: Discontinuous Reception (DRX) cycle of the UE (T may be determined by the shortest value of the UE-specific DRX value (if assigned by higher layers) and the default DRX value broadcasted in the system information. If UE-specific DRX is not configured by higher layers, the default value may be applied);

[0114] nB: total number of paging occasions in T;

[0115] N: min(T,nB);

[0116] UE ID: International Mobile Subscriber Identity (IMSI) mod 1024

[0117] The parameter nB and the length of the default DRX paging may be signaled in SIB1;

[0118] PF = "first reference point" + offset;

[0119] The offset may be signaled in SIB1.

[0120] Let i_s = floor(UE_ID / N) mod Ns; where Ns = max(1, nB / T).

[0121] In some cases, the default association Ns is 1 or 2. For Ns=1, PO is the set of RMSI monitoring opportunities in PF. For Ns=2, PO is the set of RMSI monitoring opportunities in the first half frame (i_s=0) or the second half frame (i_s=1) of PF.

[0122] In other examples, the defined search space information element (IE) may be used to define a "universal" paging / OSI monitoring window corresponding to all SSBs. In some other examples, the defined search space IE may be used to define beam-specific paging / OSI monitoring windows corresponding to different SSBs. In such a case, the base station 105-a may configure search spaces for up to 64 SSBs separately for both paging and OSI.

[0123] As indicated above, in some cases the duration of a paging occasion may be adjusted to accommodate uplink timeslots or other timeslots that may invalidate a paging DCI. Figure 3 An example of paging monitoring window 300 adjustment to support paging configuration in beamforming wireless communications in accordance with aspects of the present disclosure is illustrated. In some examples, paging monitoring window 300 can implement aspects of wireless communication systems 100 or 200.

[0124] exist Figure 3In the example of , the base station can configure a downlink / uplink (D / U) mode 305, in which a number of time slots can be defined, which can include one or more uplink (U) time slots 320 and other downlink (D) time slots. In addition, the base station can configure a paging monitoring window 310 with, for example, five paging window time slots 325. However, if one or more paging window time slots 325 will conflict with invalid paging DCI time slots (such as uplink time slots 320 in this example), the paging monitoring window can be adjusted to accommodate such time slots, thereby resulting in an actual paging monitoring window 310. In some cases, the RMSI monitoring window is not invalidated, but the random access channel (RACH) opportunity is invalidated based on the SSB and downlink time slot position. In some cases, timeslots may be invalidated based on uplink position (e.g., configured by tdd-dl-ul-config-common or tdd-dl-ul-config-common2), RACH position, RMSI search space (e.g., if non-overlap between RMSI and OSI is desired).

[0125] Figure 4 An example of an ordering 400 based on SSB index and DCI position for supporting paging configuration in beamforming wireless communication according to various aspects of the present disclosure is illustrated. In some examples, the ordering 400 based on SSB index and DCI position can implement various aspects of the wireless communication system 100 or 200. In some cases, the association between the SSB actually transmitted and the monitoring window of the PDCCH containing the paging DCI and the broadcast OSI DCI can be configured via RMSI, respectively. In addition, the SSB actually transmitted can be configured via SIB1 and RRC (e.g., via servingcellConfigCommon (serving cell configuration common) information). In the case of using SIB1 to indicate SSB, two eight-bit strings can be provided, wherein the first bit string (e.g., "inOneGroup (in a group)" bit string) indicates which SSB group is activated, and the second bit string (e.g., "groupPresence (group presence)" bit string) indicates which SSBs within each activated group are activated. In the case of using RRC signaling to indicate SSB, a 64-bit bit map can provide an explicit indication about each SSB.

[0126] For example, SIB1 may configure "inOneGroup" to 10001000 and "groupPresence" to 11000000. Such a configuration means that the first, fifth, ninth, and thirteenth SSBs are transmitted, while the remaining SSBs are not transmitted. In addition, the RRC signaling may include "ServingCellConfigCommon", which signals that the first, fifth, sixth, ninth, and thirteenth SSBs are transmitted (i.e., a 64-bit bitmap indication 10001100-10001000-0...0). In such a case, if the network sorts the paging DCI based on the actual transmitted SSBs communicated via servingCellConfigCommon, the connected mode UE may have a paging search space according to the paging DCI position index and the corresponding SSB index as indicated at 405. However, an idle mode UE that identifies the SSB based on SIB1 may have a paging DCI corresponding to the paging search space according to the paging DCI position index and the corresponding SSB index as indicated at 410. Therefore, such an idle mode UE may wait for SSB#9 in location index #3 but may not find SSB#9. Additionally, if the base station sorts the paging DCI based on the actual transmitted SSBs communicated via SIB1, the connected mode UE may not receive the paging DCI corresponding to SSB#6. Figure 5 ) provides an ordering of SSB indices and DCI positions to provide a search space that can be used by the UE.

[0127] Figure 5 An example of SSB index and DCI position based ordering 500 to support paging configurations in beamformed wireless communications in accordance with aspects of the present disclosure is illustrated. In some examples, SSB index and DCI position based ordering 500 can implement aspects of wireless communication system 100.

[0128] In this example, the ordered search space 505 may be sorted as follows: First, by the actual transmitted SSB conveyed via SIB1 (e.g., ssb-positionInBurst in SystemInformationBlockType1), such as Figure 5 , and secondly, according to the actual transmitted SSB communicated via RRC (e.g., ssb-PositionInBurst in ServingCellConfigCommon), such as Figure 5In other cases, the ordering may be reversed, in which case the starting position of the paging DCI may be configured differently between idle and connected mode UEs.

[0129] In some cases, the first order and the second order of the search space may be interleaved. For example, assume that the paging DCI corresponding to each SSB in both the first plurality of paging occasions or the first set of paging occasions and the second plurality of paging occasions or the second set of paging occasions occurs after every two slots. The first plurality occurs at even slots, while the second plurality occurs at odd slots. Idle mode UEs may not have any ambiguity because they may not search for paging in odd slots, while connected mode UEs know enough information and thus have no ambiguity.

[0130] Figure 6 An example of a paging search space configuration 600 with beam swept SSB for supporting paging configuration in beamformed wireless communications in accordance with various aspects of the present disclosure is illustrated. As discussed herein, NR allows a network (e.g., via a base station) to configure a paging search space for a UE. The paging search space allows the network to flexibly configure the periodicity, offset, duration, and monitoring symbols within a time slot. Thus, the network can use such parameters, along with the location of the first paging monitoring occasion (e.g., PDCCH monitoring occasion) for each paging occasion that is explicitly configured. The paging search space configuration 600 shows that each time slot has multiple symbols, where multiple monitoring symbols (in Figure 6 with shadow in the middle).

[0131] Figure 7 An example of mapping between SSBs and paging monitoring occasions of a paging search space configuration 700 with beam swept SSBs for paging configuration in beamforming wireless communications in accordance with various aspects of the present disclosure is illustrated. A network may define a non-default association between an SSB and a paging monitoring occasion. For example, a network may adopt a configured paging search space, such as the paging search space configuration 700. More specifically, the network may define the association using the location of the first paging monitoring occasion of the explicitly configured paging occasion and other parameters of the paging search space configuration 700 (e.g., monitoringSlotPeriodicityAndOffset, duration, and monitoringSymbolsWithinSlot). In this way, no additional RRC parameters are introduced.

[0132] The paging search space configuration 700 provides a one-to-one mapping between SSBs and paging monitoring opportunities (eg, PDCCH monitoring opportunities). Figure 7Different shaded symbols in the paging monitoring occasions corresponding to different SSBs are indicated. SSBs can be mapped to different paging monitoring occasions consecutively. If there are multiple paging monitoring occasions in a time slot, different SSBs can be mapped to different paging monitoring occasions in a time slot. In the paging search space configuration 700, two paging monitoring occasions are defined in a time slot. Therefore, two different SSBs can be mapped to two paging monitoring occasions in each time slot.

[0133] In the paging search space configuration 700, the first paging opportunity 705 (e.g., the Nth paging opportunity) may include two paging search space instances 710 and 715, each of which includes two time slots. As shown, multiple paging monitoring opportunities may be configured for each time slot, where different SSBs are mapped to different paging monitoring opportunities of the corresponding time slots. For example, the first paging monitoring opportunity of the first paging opportunity 705 (corresponding to the first actually transmitted SSB) may be the monitoring code element 720, and the fifth paging monitoring opportunity of the first paging opportunity 705 (corresponding to the first actually transmitted SSB) may be the monitoring code element 725. Similarly, the second paging opportunity 730 (e.g., the (N+1)th paging opportunity) may include two paging search space instances 735 and 740, each of which includes two time slots. For the second paging opportunity 730, the first paging monitoring opportunity may be the monitoring code element 745, and the fifth monitoring opportunity may be the monitoring code element 750.

[0134] Alternatively or additionally, a non-default association between an SSB and a paging monitoring opportunity (as supported, for example, by a technical specification) may be defined as follows. The network may confirm that the location of the first paging monitoring opportunity (if explicitly configured) matches a valid PDCCH monitoring opportunity defined by the paging search space. Starting from the first paging PDCCH monitoring opportunity, N valid consecutive monitoring opportunities may be defined based on the parameters of the paging search space (e.g., MonitoringSlotPeriodicityAndOffset, duration, and monitoringSymbolsWithinSlot), which may be set forth in a paging search space information element (IE), where N is the number of SSBs actually transmitted. The SSB index may be mapped consecutively to N valid paging monitoring opportunities. Each SSB may be mapped to only one valid paging monitoring opportunity within one paging opportunity. As above, if there are multiple paging monitoring opportunities within a time slot, different SSBs may be mapped to different paging monitoring opportunities within the time slot.

[0135] If the network has mixed time slots (i.e., a combination of downlink / sidelink (D / S) and uplink (U) within a time slot), the network may configure the paging search space so that paging monitoring opportunities (e.g., paging PDCCH monitoring opportunities) do not occur in time slots where there are insufficient resources to schedule paging physical downlink shared channels (PDSCH). However, the availability of paging PDSCH resources may not affect the validity of paging PDCCH monitoring opportunities.
