Technical Field

[0003] Various aspects of the present disclosure relate generally to wireless communication systems, and more particularly to tracking reference signal (TRS) / channel state information reference signal (CSI-RS) multiplexing with paging and / or broadcast messages for idle and / or inactive mode user equipment (UE) in wireless communication systems such as fifth generation new radio (5G NR). Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems may be multiple-access systems 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 code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and single-carrier frequency division multiple access (SC-FDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, or even global level. For example, the fifth generation (5G) wireless communication technology (which may be referred to as NR) is envisioned to extend and support different usage scenarios and applications with respect to current mobile network generations. In one aspect, 5G communication technology may include: enhanced mobile broadband addressing people-centric use cases for accessing multimedia content, services, and data; ultra-reliable low-latency communications (URLLC) with certain latency and reliability specifications; and massive machine-type communications, which may allow for very large numbers of connected devices and the transmission of relatively small amounts of non-latency sensitive information.

[0006] For example, for various communication technologies such as, but not limited to, NR, some implementations may increase transmission speed and flexibility, but may also increase transmission complexity. Therefore, improvements to wireless communication operations may be desired. Summary of the invention

[0025] Various aspects are now described with reference to the accompanying drawings. In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. However, it may be apparent that this (one or more) aspect can be practiced without these specific details.

[0026] The described features generally relate to UE-specific reference signals (UE-RS) (e.g., tracking reference signals (TRS) / channel state information (CSI) reference signals (CSI-RS)) multiplexing with paging and / or broadcast messages of idle and / or inactive mode user equipment (UE) in a wireless communication system such as the fifth generation new radio (5G NR or referred to as NR). In one example, UE power saving enhancements may include enhancements to power saving of idle and / or inactive mode UEs in consideration of system performance. Examples of this enhancement may include a designated paging enhancement that reduces unnecessary UE paging reception and a component that provides potential TRS / CSI-RS opportunities available to idle and / or inactive mode UEs in connected mode, thereby minimizing system overhead impact. Power saving enhancements may also include tracking of idle and / or inactive mode UEs in NR. For example, there are no reference signals that are always on in NR (e.g., cell-specific reference signals (CRS) in LTE). UE-specific reference signals (e.g., TRS / CSI-RS) may be configured for connected mode UEs. In another example, an idle and / or inactive mode UE relies on synchronization signal blocks (SSBs) in NR. The periodicity of NR SSBs (e.g., 20ms) may be much sparser than LTE CRS. For UE modem implementations that use SSBs as input to a tracking loop (e.g., frequency tracking loop / time tracking loop (FTL / TTL)), it may be useful for the UE to receive one or more SSBs, especially in poor channel conditions. The UE may be able to enter "light sleep" between SSBs and / or paging occasions (POs), but overall, this reduces deep sleep time and incurs multiple wake-up and / or sleep entry overhead.

[0027] The present disclosure generally relates to current problems of utilizing UE-RS for idle and / or inactive mode UEs.For example, the UE-RS is configured to be located in symbols and / or slots as close as possible to paging transmissions.

[0028] In one aspect, the present disclosure includes methods, apparatus, and non-transitory computer-readable media for wireless communications, the methods, apparatus, and non-transitory computer-readable media being used to: receive an indication from a network entity to multiplex a UE-RS with one or more broadcast messages, wherein the UE-RS includes a TRS / CSI-RS; monitor the one or more broadcast messages during at least one of an idle or inactive mode of the UE; and decode the one or more broadcast messages based at least on the one or more UE-RS.

[0029] In another aspect, the present disclosure includes a method, an apparatus, and a non-transitory computer-readable medium for wireless communication, the method, the apparatus, and the non-transitory computer-readable medium being used to: send an indication to one or more UEs to multiplex a UE-RS with one or more broadcast messages, wherein the UE-RS includes a TRS / CSI-RS; and send one or more broadcast messages to one or more UEs for decoding based on the UE-RS, wherein at least one of the one or more UEs operates in an idle or inactive mode.

[0030] The following will refer to Figure 1-Figure 7 The described features are presented in more detail.

[0031] As used in this application, the terms "component", "module", "system", etc. are intended to include computer-related entities, such as but not limited to hardware, software, a combination of hardware and software, or software in execution. For example, a component can be, but not limited to, a process, a processor, an object, an executable file, an execution thread, a program, and / or a computer running on a processor. As an illustration, both an application running on a computing device and a computing device can be a component. One or more components can reside in a process and / or an execution thread, and a component can be located on a computer and / or distributed between two or more computers. In addition, these components can be executed from various computer-readable media having various data structures stored thereon. These components can communicate through local and / or remote processes, such as according to a signal with one or more data packets, such as data from a component, the component interacts with another component in a local system, a distributed system, and / or interacts with other systems through a network such as the Internet. Software shall be construed broadly to include instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subprograms, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0032] The technology described herein can be used for various wireless communication systems, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms "system" and "network" are usually used interchangeably. A CDMA system can implement radio technology, such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. IS-2000 version 0 and A are commonly referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO, High Speed ​​Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. A TDMA system can implement radio technology, such as Global System for Mobile Communications (GSM). An OFDMA system may implement a radio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM TM Etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are new versions of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein can be used for the above-mentioned systems and radio technologies as well as other systems and radio technologies, including cellular (e.g., LTE) communications on shared radio spectrum bands. However, the following description describes an LTE / LTE-A system for example purposes, and LTE terminology is used in most of the following description, although these techniques are applicable outside LTE / LTE-A applications (e.g., fifth generation (5G) NR networks or other next generation communication systems).

[0033] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. The functions and arrangements of the elements discussed may be changed without departing from the scope of the present disclosure. Various examples may appropriately omit, replace or add various processes or components. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted or combined. In addition, the features described with respect to some examples may be combined in other examples.

[0034] Various aspects or features will be presented in terms of systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that the various systems may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. Combinations of these schemes may also be used.

[0035] refer to Figure 1 , an example of a wireless communication system and access network 100 (also referred to as a wireless wide area network (WWAN)) may include a base station 102, a UE 104, an evolved packet core (EPC) 160, and / or a 5G core (5GC) 190. The base station 102 (which may also be referred to as a network entity) may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell may include a base station. A small cell may include a femto cell, a pico cell, and a macro cell. In an example, the base station 102 may also include a gNB 180 as further described herein.

[0036] In one example, some nodes such as base station 102 / gNB 180 may have a modem 240 and a communication component 242 as described herein. For example, base station 102 and / or communication component 242 may receive an indication from network entity 102 to multiplex a UE-RS with one or more broadcast messages, wherein the UE-RS includes a TRS / CSI-RS, monitor the one or more broadcast messages during at least one of an idle or inactive mode of UE 104, and decode the one or more broadcast messages based at least on the one or more UE-RS. Although base station 102 / gNB 180 is shown as having a modem 240 and a communication component 242, this is an illustrative example, and substantially any node may include a modem 240 and a communication component 242 to provide the corresponding functionality described herein.

[0037] In another example, some nodes, such as UE 104 of a wireless communication system, may have a modem 340 and a communication component 342 for sending an indication to multiplex a UE-RS with one or more broadcast messages to one or more UEs 104, wherein the UE-RS includes a TRS / CSI-RS, and sending one or more broadcast messages for decoding based on the UE-RS to the one or more UEs 104, wherein at least one of the one or more UEs 104 is operating in an idle or inactive mode. Although the UE 104 is shown with the modem 340 and the communication component 342, this is an illustrative example, and substantially any node or node type may include the modem 340 and the communication component 342 to provide the corresponding functionality described herein.

[0038] Base stations 102 configured for 4G LTE (which may be collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with EPC 160 via a backhaul link 132 (e.g., using an S1 interface). Base stations 102 configured for 5G NR (which may be collectively referred to as Next Generation RAN (NG-RAN)) may interface with 5GC 190 via a backhaul link 184. Among other functions, the base station 102 may perform one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, non-access stratum distribution (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, positioning, and transmission of warning messages. Base stations 102 may communicate with each other directly or indirectly (e.g., via EPC 160 or 5GC 190) via backhaul links 134 (e.g., using an X2 interface). Backhaul links 132, 134, and / or 184 may be wired or wireless.

[0039] The base station 102 can communicate wirelessly with one or more UEs 104. Each base station 102 can provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102' can have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include a home evolved Node B (eNB) (HeNB), which can provide services to a restricted group, which can be referred to as a closed subscriber group (CSG). The communication link 120 between the base station 102 and the UE 104 can include an uplink (UL) (also referred to as a reverse link) transmission from the UE 104 to the base station 102 and / or a downlink (downlink) (also referred to as a forward link) transmission from the base station 102 to the UE 104. The communication link 120 can use multiple input multiple output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link can be through one or more carriers. The base station 102 / UE 104 can use spectrum of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth for each carrier allocated in a total carrier aggregation of Yx MHz (e.g., for x component carriers) for transmission in the DL and / or UL direction. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0040] In another example, some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through various wireless D2D communication systems, such as FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on IEEE 802.11 standards, LTE, or NR.

[0041] The wireless communication system may further include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) prior to communication to determine whether the channel is available.

[0042] The small cell 102' can operate in a licensed and / or unlicensed spectrum. When operating in an unlicensed spectrum, the small cell 102' can employ NR and use the same 5 GHz unlicensed spectrum used by the Wi-Fi AP 150. The small cell 102' employing NR in the unlicensed spectrum can improve the coverage of the access network and / or increase the capacity of the access network.

[0043] Base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), may include an eNB, a gNode B (gNB), or other types of base stations. Some base stations, such as gNB 180, may operate in traditional sub-6 GHz spectrum, in millimeter wave (mmW) frequencies, and / or near mmW frequencies to communicate with UE 104. When gNB 180 operates at mmW or near mmW frequencies, gNB 180 may be referred to as a mmW base station. Extremely high frequency (EHF) is part of the RF in the electromagnetic spectrum. EHF has a frequency range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near mmW may extend below 3 GHz frequency with a wavelength of 100 mm. The super high frequency (SHF) band extends between 3 GHz and 30 GHz and is also referred to as centimeter waves. Communications using mmW / near mmW radio frequency bands have extremely high path loss and short distances. The mmW base station 180 can utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short distance. The base station 102 mentioned in this article can include a gNB 180.

[0044] The EPC 160 may include a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a packet data network (PDN) gateway 172. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Typically, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides IP address allocation to the UE as well as other functions. The PDN gateway 172 and the BM-SC 170 are connected to IP services 176. The IP services 176 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a packet switched (PS) streaming service, and / or other IP services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS delivery, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and may be used to schedule MBMS delivery. The MBMS Gateway 168 may be used to distribute MBMS services to base stations 102 belonging to a multicast broadcast single frequency network (MBSFN) area of ​​a broadcast specific service, and may be responsible for session management (start / stop) and collecting MBMS-related billing information.

[0045] 5GC 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. AMF 192 may communicate with unified data management (UDM) 196. AMF 192 may be a control node that handles signaling between UE 104 and 5GC 190. Typically, AMF 192 may provide QoS flow and session management. User Internet Protocol (IP) packets (e.g., from one or more UEs 104) may be transmitted through UPF 195. UPF 195 may provide UE IP address allocation and other functions for one or more UEs. UPF 195 is connected to IP services 197. IP services 197 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services.

[0046] A base station may also be referred to as a gNB, a Node B, an evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit receive point (TRP), or some other suitable terminology. Base station 102 provides an access point to EPC 160 or 5GC 190 for UE 104. Examples of UE 104 include cellular phones, smart phones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, positioning systems (e.g., satellite, terrestrial), multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, robots, drones, industrial / manufacturing equipment, wearable devices (e.g., smart watches, smart clothing, smart glasses, virtual reality goggles, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), vehicle / onboard equipment, meters (e.g., parking meters, electric meters, gas meters, water meters, flow meters), gas pumps, large or small kitchen appliances, medical / health care equipment, implants, sensors / actuators, displays, or any other similarly functional devices. Some UE 104 may be referred to as IoT devices (e.g., meters, pumps, monitors, cameras, industrial / manufacturing equipment, appliances, vehicles, robots, drones, etc.). IoT UEs may include machine type communication (MTC) / enhanced MTC (eMTC, also referred to as Category (CAT)-M or Cat M1) UEs, NB-IoT (also referred to as CAT NB1) UEs, and other types of UEs. In the present disclosure, eMTC and NB-IoT may refer to future technologies that may evolve from or may be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), mMTC (massive MTC), etc., and NB-IoT may include eNB-IoT (enhanced NB-IoT), FeNB-IoT (further enhanced NB-IoT), etc. UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a mobile phone, a user agent, a mobile client, a client, or some other suitable terminology.

[0050] In addition, the memory 216 can be configured to store data used herein and / or local versions of the applications 275 or the communication component 242 and / or one or more subcomponents thereof executed by the at least one processor 212. The memory 216 may include any type of computer-readable medium usable by a computer or the at least one processor 212, such as random access memory (RAM), read-only memory (ROM), tape, disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, the memory 216 may be a non-transitory computer-readable storage medium that stores one or more computer-executable codes defining the communication component 242 and / or one or more subcomponents thereof and / or data associated therewith when the UE 104 operates the at least one processor 212 to execute the communication component 242 and / or one or more subcomponents thereof.

[0051] The transceiver 202 may include at least one receiver 206 and at least one transmitter 208. The receiver 206 may include hardware and / or software executable by a processor for receiving data, the code including instructions and stored in a memory (e.g., a computer-readable medium). The receiver 206 may be, for example, a radio frequency (RF) receiver. In one aspect, the receiver 206 may receive a signal transmitted by at least one base station 102. In addition, the receiver 206 may process such received signals and may also obtain measurements of the signal, such as, but not limited to, Ec / Io, signal-to-noise ratio (SNR), reference signal received power (RSRP), received signal strength indicator (RSSI), etc. The transmitter 208 may include hardware and / or software executable by a processor for transmitting data, the code including instructions and stored in a memory (e.g., a computer-readable medium). Suitable examples of the transmitter 208 may include, but are not limited to, an RF transmitter.

[0052] In addition, in an aspect, the base station 102 may include an RF front end 288, which may communicate with one or more antennas 265 and the transceiver 202 for receiving and sending radio transmissions, such as wireless communications sent by at least one base station 102 or wireless transmissions sent by the UE 104. The RF front end 288 may be connected to the one or more antennas 265 and may include one or more low noise amplifiers (LNAs) 290, one or more switches 292, one or more power amplifiers (PAs) 298, and one or more filters 296 for sending and receiving RF signals. The antenna 265 may include one or more antennas, antenna elements, and / or antenna arrays.

[0053] In one aspect, the LNA 290 can amplify the received signal at a desired output level. In one aspect, each LNA 290 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular LNA 290 and its specified gain value based on the desired gain value for a particular application.

[0054] Further, for example, the RF front end 288 can use one or more PAs 298 to amplify the signal of the RF output at a desired output power level. In one aspect, each PA 298 can have a specified minimum and maximum gain value. In one aspect, the RF 288 can use one or more switches 292 to select a specific PA 298 and its specified gain value based on the desired gain value of a particular application.

[0055] In addition, for example, the RF front end 288 can use one or more filters 296 to filter the received signal to obtain an input RF signal. Similarly, in one aspect, for example, a corresponding filter 296 can be used to filter the output from the respective PA 298 to produce an output signal for transmission. In one aspect, each filter 296 can be connected to a specified LNA 290 and / or PA 298. In one aspect, based on the configuration specified by the transceiver 202 and / or the processor 212, the RF front end 288 can use one or more switches 292 to select a transmit or receive path using a specific filter 296, LNA 290, and / or PA 298.

[0056] Thus, the transceiver 202 may be configured to transmit and receive wireless signals through one or more antennas 265 via the RF front end 288. In an aspect, the transceiver may be tuned to operate at a specified frequency so that the UE 104 may communicate with, for example, one or more base stations 102 or one or more cells associated with the one or more base stations 102. In an aspect, the modem 240 may configure the transceiver 202 to operate at a specified frequency and power level based on, for example, a UE configuration of the UE 104 and a communication protocol used by the modem 240.

[0057] In one aspect, the modem 240 can be a multi-band multi-mode modem that can process digital data and communicate with the transceiver 202 so that the digital data is sent and received using the transceiver 202. In one aspect, the modem 240 can be multi-band and configured to support multiple frequency bands of a specified communication protocol. In one aspect, the modem 240 can be multi-mode and configured to support multiple operating networks and communication protocols. In one aspect, the modem 240 can control one or more components (e.g., RF front end 288, transceiver 202) of the UE 104 to enable the transmission and / or reception of signals from the network based on the specified modem configuration. In one aspect, the modem configuration can be based on the mode of the modem and the frequency band used. On the other hand, the modem configuration can be based on the UE configuration information associated with the UE 104 provided by the network during cell selection and / or cell reselection.

[0058] In one aspect, the processor(s) 212 may correspond to a processor that is associated with Figure 7 Similarly, the memory 216 may correspond to one or more of the processors described in the base station in the embodiment of the present invention. Figure 7 The memory described by the base station in.

[0059] refer to Figure 3 , one example of an implementation of the UE 104 may include a variety of components, some of which have been described above and will be further described herein, including components that communicate via one or more buses 344, such as one or more processors 312 and memory 316 and transceiver 302, which may operate in conjunction with a modem 340. In one aspect, for example, the memory 316 may be a non-transitory computer-readable storage medium that stores one or more computer-executable codes defining the communication component 342 and / or one or more subcomponents thereof and / or data associated therewith when the UE 104 is operating at least one processor 312 to execute the communication component 342 and / or one or more subcomponents thereof for enhanced SRS-based CLI measurements.

[0060] The transceiver 302, receiver 306, transmitter 308, one or more processors 312, memory 316, application 375, bus 344, RF front end 388, LNA 390, switch 392, filter 396, PA 398, and one or more antennas 365 may be the same or similar to corresponding components of the base station 102 described above, but configured or otherwise programmed for UE operation as opposed to base station operation.

[0061] In one aspect, the processor(s) 312 may correspond to a processor that is associated with Figure 7 Likewise, the memory 316 may correspond to one or more of the processors described in the base station of FIG. Figure 7 The memory described by the base station in.

[0062] refer to Figure 4 , an example diagram 400 of resources varying over time includes paging messages in NR. The paging mechanism in NR is different compared to LTE. For example, in LTE, CRS can be sent periodically, which allows sample capture around paging and enables offline mode implementation. For NR, CRS is not sent - only SSBs are used as reference signals (e.g., 20ms periodicity), and offline mode may not be configured due to the potentially large gap between each SSB and each paging physical downlink control channel (PDCCH). In addition, in NR, paging messages can be beamformed. For FR2, up to 64 beamformed SSBs can be sent. For example, up to 64 beamformed paging copies can be sent (with a one-to-one correspondence to the SSBs). The UE can select the best beam based on the SSB and decode the corresponding paging.

[0063] In one aspect, UE-RS (e.g., TRS / CSI-RS) can be configured for idle and / or inactive mode UEs. For example, enabling TRS / CSI-RS measurements for idle and / or inactive mode UEs, idle and / or inactive mode UEs can rely less on SSBs for tracking, which can improve overall UE power efficiency. Signaling of TRS / CSI-RS to idle and / or inactive mode UEs can include several different signaling methods because idle and / or inactive mode UEs do not have dedicated signaling to the base station. In one example, the signaling method may include a short message (e.g., a PDCCH with a cyclic redundancy check (CRC) scrambled by a P-RNTI) that reserves bits for short messages in downlink control information (DCI) format 1_0. In another example, a paging message can be utilized, such as a physical downlink shared channel (PDSCH) scheduled by a PDCCH with a CRC scrambled by a P-RNTI. In another example, a new paging DCI may be utilized that signals at least the TRS / CSI-RS opportunity configuration and / or an identifier for the paging / UE group.The new paging DCI may be a separate resource from the traditional paging DCI.

[0064] In one aspect, paging and other broadcast messages (e.g., system information blocks) for idle and / or inactive mode UEs do not support rate matching around TRS / CSI-RS. For example, according to 'ssb-PositionInBurst' in SIB1, broadcast messages (e.g., PDSCH scheduled with SI-RNTI (other SI outside SIB1), RA-RNTI, MsgB-RNTI, P-RNTI, or TC-RNTI) are rate matched around SSB. There is also no rate matching for broadcast messages of TRS / CSI-RS. The network can avoid conflicts between TRS / CSI-RS and broadcast messages for other connected mode UEs. When TRS / CSI-RS is used for idle and / or inactive mode UEs (e.g., for paging performance and power efficiency improvements), TRS / CSI-RS can be configured to be as close to the paging transmission as possible. For example, TRS / CSI-RS can be located in the same time slot or on the same symbol where a paging message (e.g., PDSCH) is scheduled (i.e., FDM).

[0065] Therefore, the current aspects include TRS / CSI-RS multiplexing for broadcast messages.

[0066] The first aspect includes rate matching the TRS / CSI-RS for idle / inactive mode UEs. For example, if a UE is indicated with TRS resources for paging enhancement, it can rate match around its own TRS / CSI-RS. Alternatively, similar to 'ssb-PositionInBurst', parameters for the TRS rate matching pattern may be included in system information (SI) (e.g., master information block (MIB) / SIB1). In some cases, some UEs may be allocated additional resources for paging / broadcasting (e.g., for offloading purposes).

[0067] The second aspect includes puncturing the TRS / CSI-RS for idle / inactive mode UEs. In this case, when TRS / CSI-RS are multiplexed, the resource elements (REs) of the paging / broadcast messages corresponding to the TRS / CSI-RS REs are replaced by TRS / CSI-RS. If TRS resources are indicated, the UE can identify the punctured REs and can decode the paging / broadcast messages. For other UEs that cannot identify puncturing, such UEs can assume that all REs are used for paging / broadcast messages.

[0068] The indication of the TRS / CSI-RS multiplexing scheme may vary. For example, rate matching or puncturing may be employed for different cells or for different durations and indicated by system information (e.g., MIB / SIB). Alternatively, the radio resource control (RRC) release message of an idle / inactive mode UE may indicate the multiplexing scheme used for a neighboring cell.

[0069] refer to Figure 5 An example of a method 500 for wireless communication at a UE, such as UE 104, may use Figure 1 , Figure 2 , Figure 3 and Figure 7 104 to perform TRS / CSI-RS multiplexing of paging / broadcast messages with idle / inactive mode UEs as described herein.

[0070] At box 502, method 500 includes receiving an indication from a network entity to multiplex a UE-RS with one or more broadcast messages, wherein the UE-RS includes a TRS / CSI-RS.

For example, in one aspect, UE 104 and / or communication component 342 may configure processor 312 and / or transceiver 302 to monitor, and / or perform operations such as described above with respect to Figure 3 Other signal processing described.

[0098] refer to Figure 7 , an example of a MIMO communication system 700 includes a base station 102 and a UE 104, where the base station 102 can act as an integrated access and backhaul (IAB) node or parent node. The base station 102 and the UE 104 can be the same as described above and can include the reference Figure 7 The MIMO communication system 700 may be described with reference to Figure 1 Aspects of the wireless communication access network 100 described. The base station 102 can be equipped with antennas 734 and 735, and the UE 104 can be equipped with antennas 752 and 753. In the MIMO communication system 700, the base station 102 may be able to send data through multiple communication links at the same time. Each communication link can be referred to as a "layer", and the "rank" of the communication link can indicate the number of layers used for communication. For example, in a 2×2 MIMO communication system in which the base station 102 sends two "layers", the rank of the communication link between the base station 102 and the UE 104 is two.

[0099] At the base station 102, a transmit (Tx) processor 720 may receive data from a data source. The transmit processor 720 may process the data.

The MIMO detector 756 can obtain received symbols from the modulator / demodulators 754 and 755, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive (Rx) processor 758 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 104 to the data output, and provide decoded control information to the processor 780 or the memory 782.

[0101] Processor 740 may, in some cases, execute stored instructions to instantiate communication component 242 (eg, see Figure 1 and Figure 2 ). Processor 780 may, in some cases, execute stored instructions to instantiate communication component 342 (eg, see Figure 1 and Figure 3 ).

The transmit processor 764 may also generate reference symbols for a reference signal. The symbols from the transmit processor 764 may be precoded by a transmit MIMO processor 766 (if applicable), further processed by modulators / demodulators 754 and 755 (e.g., for SC-FDM, etc.), and transmitted to the base station 102 according to the communication parameters received from the base station 102. At the base station 102, the UL signal from the UE 104 may be received by antennas 734 and 735, processed by modulators / demodulators 732 and 733, detected by a MIMO detector 736 (if applicable), and further processed by a receive processor 738. The receive processor 738 may output the data and provide decoded data to the processor 740 or the memory 742.

[0103] The components of UE 104 may be implemented individually or in conjunction with one or more ASICs employed to perform some or all of the applicable functions in hardware. Each of the modules indicated may be a component for performing one or more functions related to the operation of MIMO communication system 1000. Similarly, the components of base station 102 may be implemented individually or in conjunction with one or more ASICs employed to perform some or all of the applicable functions in hardware.
