Abstract
Description
Technical Field
[0001] In summary, various aspects of this disclosure relate to wireless communication and techniques and apparatus for configuring reference signals for user equipment in idle or inactive modes. Background Technology
[0002] Wireless communication systems have been widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies 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, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).
[0003] A wireless network may include multiple base stations (BSs), which can support communication between multiple user equipment (UEs). UEs can communicate with BSs via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmitter Receiver Point (TRP), New Radio (NR) BS, 5G Node B, etc.
[0004] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate across city limits, countries, regions, and even globally. NR (which can also be called 5G) is an evolution set of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, reducing costs, enhancing service, fully utilizing new spectrum, using Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) on the downlink, using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0025] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided only to make this disclosure thorough and complete, and to fully convey the scope of protection of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should understand that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, an apparatus or method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods that may be implemented using other structures, functions, or structures and functions other than those set forth herein, or structures and functions different from those set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more components of the invention.
[0026] Now, some aspects of a telecommunications system will be given with reference to various devices and techniques. These devices and techniques will be described in the following detailed embodiments and depicted in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0027] It should be noted that although this document uses terms commonly associated with 5G or NR radio access technology (RAT) to describe aspects of this document, aspects of this disclosure may also be applied to other RATs (e.g., 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G)).
[0028] Figure 1This diagram illustrates an example of a wireless network 100 according to various aspects of this disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc., or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, node B, gNB, 5G node B (NB), access point, transport receiver point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, depending on the context in which the term "cell" is used, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area.
[0029] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers), allowing unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area, allowing unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home), allowing restricted access for UEs associated with that femtocell (e.g., UEs in a closed user group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably throughout this document.
[0030] In some respects, the cell does not need to be stationary; the geographical area of the cell can move depending on the location of the mobile BS. In other respects, BSs can use any suitable transport network to interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections or virtual networks).
[0031] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit those data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions from other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be called a relay station, relay base station, repeater, etc.
[0032] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, repeater BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have higher transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and repeater BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).
[0033] Network controller 130 can be coupled to a group of base stations (BSs) and provide coordination and control for these BSs. Network controller 130 can communicate with these BSs via backhaul. These BSs can also communicate with each other, for example, directly or indirectly via wireless or wired backhaul communication links.
[0034] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device or a satellite radio device), an in-vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.
[0035] Some UEs can be viewed as Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. For example, MTC UEs and eMTC UEs may include robots, drones, remote devices, sensors, meters, monitors, and / or location tags capable of communicating with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 may be included in a housing that houses the components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electrically coupled, and / or electronically coupled.
[0036] Typically, any number of wireless networks can be deployed within a given geographical area. Each wireless network can support a specific Radio Access Platform (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT within a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.
[0037] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more lateral link channels (e.g., without using base station 110 as an intermediary device). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicular (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein that are performed by base station 110.
[0038] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) and / or an operating band with a second frequency range (FR2), where FR1 can range from 410 MHz to 7.125 GHz and FR2 can range from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the “sub-6 GHz” band. Similarly, FR2 is often referred to as the “millimeter wave” band, although it differs from the Extremely High Frequency (EHF) band (30 GHz–300 GHz) recognized as a “millimeter wave” band by the International Telecommunication Union (ITU). Therefore, unless otherwise explicitly stated, it should be understood that the terms "sub-6 GHz," etc. (if used herein), can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or may include intermediate frequency band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms "millimeter wave," etc. (if used herein), can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or may include intermediate frequency band frequencies (e.g., less than 24.25 GHz). These frequencies included in FR1 and FR2 can be modified, and the techniques described herein can be applied to these modified frequency ranges.
[0039] As indicated above, Figure 1 Examples are provided. Other examples can be found in the reference. Figure 1 The examples described are different.
[0040] Figure 2 This diagram illustrates an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100, based on various aspects of this disclosure. The base station 110 may be equipped with... T The UE 120 can be equipped with antennas 234a to 234t. R Antennas 252a to 252r (where T ≥ 1) , R ≥ 1).
[0041] At base station 110, transmit processor 220 can receive data from data source 212 intended for one or more UEs, select one or more modulation and coding schemes (MCS) for the UE based at least in part on channel quality indicators (CQI) received from the UE, process the data for the UE (e.g., coding and modulation) based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on these data symbols, control symbols, overhead symbols, and / or reference symbols (if any), and transmit the data to the UE. T Modulators (MODs) 232a to 232t provide T Each modulator 232 can process its own output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can also process (e.g., convert to analog signal, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The signals from modulators 232a to 232t... T Each downlink signal can be transmitted via T Each antenna, from 234a to 234t, transmits.
[0042] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) its respective received signal to obtain an input sample. Each demodulator 254 can also process these input samples (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can receive downlink signals from all base stations. RDemodulators 254a to 254r acquire received symbols, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or Channel Quality Indicator (CQI) parameters, etc. In some aspects, one or more components of UE 120 may be included in housing 284.
[0043] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.
[0044] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or be included in, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include a set of coplanar antenna elements and / or a set of non-coplanar antenna elements. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements within a single housing, and / or antenna elements included in multiple housings. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.
[0045] On the uplink, at UE 120, transmit processor 264 can receive data from data source 262 and control information (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280, and process the data and control information. Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-coded (if any) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted back to base station 110. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receiver processor 258, transmitter processor 264, and / or TX MIMO processor 266. The processor (e.g., controller / processor 280) and memory 282 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figure 4-9 (as described).
[0046] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if any), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes transceivers. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TX MIMO processor 230. The processor (e.g., controller / processor 240) and memory 242 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figure 4-9 (as described).
[0047] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other components may perform one or more techniques associated with the reference signals configured for the UE in idle mode or inactive state, as described in further detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 8 Processing 800 Figure 9 The processing 900 and / or other processing operations as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when said one or more instructions are executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), it may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 8 Processing 800 Figure 9 The processing of 900 and / or other processing operations described herein. In some aspects, the execution instructions may include run instructions, translation instructions, compilation instructions, and / or interpretation instructions, etc.
[0048] In some respects, UEs (e.g., UE 120 and / or Figure 10 The apparatus 1000 may include: for receiving signals from an NR base station (e.g., base station 110 and / or...) Figure 11 The apparatus 1100 receives a unit including an indication of a configuration for at least one reference signal; and / or a unit for measuring the at least one reference signal, at least in part, based on the indication of the configuration, when in an idle mode or inactive state.

[0050] In some aspects, the UE may include: a unit for receiving from an NR base station an additional indication that does not include a configuration for the at least one reference signal; and / or a unit for removing the configuration for the at least one reference signal from the UE's memory based at least in part on the additional indication. Alternatively or additionally, the UE may include: a unit for receiving from an NR base station an additional indication including an instruction to release the configuration for the at least one reference signal; and / or a unit for removing the configuration for the at least one reference signal from the UE's memory based at least in part on the additional indication. Alternatively or additionally, the UE may include: a unit for determining that a timer associated with the configuration for the at least one reference signal has expired; and / or a unit for removing the configuration for the at least one reference signal from the UE's memory based at least in part on the timer's expiration.
[0051] In some aspects, the UE may further include: a unit for transitioning to a connected state with an NR base station; and / or a unit for removing configurations for the at least one reference signal from the UE's memory, at least in part based on the transition to a connected state. Additionally or alternatively, the UE may include: a unit for establishing a radio resource control (RRC) connection with a new serving cell; and / or a unit for removing configurations for the at least one reference signal from the UE's memory, at least in part based on the RRC connection with the new serving cell.

In some aspects, the UE may include: a unit for receiving a paging signal from an NR base station; and a unit for measuring the at least one reference signal after receiving the paging signal and before a next paging opportunity.
[0056] In any of the aspects described above, the UE may include: a unit for receiving a message from an NR base station indicating whether the at least one reference signal will be activated and deactivated, or indicating whether the at least one reference signal will be transmitted in association with a paging of the UE.
[0057] In some aspects, base stations (e.g., base station 110 and / or Figure 11 The device 1100 may include: for sending signals to an NR UE (e.g., UE 120 and / or Figure 10 The apparatus 1000 includes a unit that transmits an indication of a configuration for at least one reference signal; and / or a unit that transmits the at least one reference signal to the NR UE, at least in part, based on the indication of the configuration, when the NR UE is in an idle mode or inactive state. The unit for the base station to perform the operations described herein may include one or more of, for example, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.
[0058] In some aspects, the base station may further include a unit for transmitting to the NR UE an additional indication that does not include the configuration for the at least one reference signal. Alternatively or additionally, the base station may include a unit for transmitting to the NR UE an additional indication that includes an instruction to release the configuration for the at least one reference signal.

[0063] Although Figure 2 The boxes in the diagram represent different components, but the functions described above with reference to these boxes can be implemented using a single hardware, software, or combination of components, or various combinations of components. For example, the functions described with reference to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280, or performed under the control of controller / processor 280.
[0064] As indicated above, Figure 2 Examples are provided. Other examples can be found in the reference. Figure 2 The examples described are different.
[0065] Figure 3AThis diagram illustrates, according to various aspects of this disclosure, an example 300 of reference signal measurements prior to a paging opportunity (PO) in LTE. Example 300 shows the signal from the base station to the LTE UE in the time domain. In example 300, the LTE UE may be in idle mode, such that the LTE UE does not have an RRC connection with the base station. Therefore, the LTE UE can wake up to monitor one or more POs. For example, the LTE UE may monitor the Physical Downlink Control Channel (PDCCH) to obtain a paging PDCCH message (e.g., encoded as Downlink Control Information (DCI)) indicating whether a paging Physical Downlink Shared Channel (PDSCH) message has been scheduled. If the paging PDCCH message does not indicate that a paging PDSCH message has been scheduled, the LTE UE can return to idle mode. If the paging PDCCH message does indicate that a paging PDSCH message has been scheduled, the LTE UE can receive and decode the paging PDSCH message and determine whether the LTE UE is being paged. If the LTE UE determines that it is being paged, the LTE UE can re-establish an RRC connection with the base station. If the LTE UE determines that it has not been paged, the LTE UE can return to idle mode.
[0066] like Figure 3A As shown, the LTE UE can measure one or more normally open reference signals (e.g., cell-specific reference signals (CRS)) transmitted by the base station in each subframe. In example 300, the LTE UE measures the CRS in slots 302a, 302b, and 302c. Therefore, the LTE UE can remain in deep sleep until within several slots or symbols of the upcoming PO 304. As used herein, a "slot" can refer to a portion of a subframe, which in turn can be a small portion of a radio frame within an LTE, 5G, or other wireless communication architecture. In some respects, a slot can include one or more symbols. Furthermore, a "symbol" can refer to an OFDM symbol or another similar symbol within a slot. By measuring the CRS, the LTE UE can update the tracking loop and estimate the time delay, frequency offset, and / or other physical characteristics of the signal from the base station before monitoring paging PDCCH messages in PO 304 (which may occupy one or more slots).
[0067] However, normally open reference signals like CRS consume unnecessary processing and network resources. Furthermore, they can degrade the quality and / or reliability of communication within the cell due to leakage interference from other signals transmitted within the cell. Therefore, NR base stations typically do not transmit normally open reference signals like CRS. Figure 3B As shown in the image.
[0068] Figure 3BThis diagram illustrates, according to various aspects of this disclosure, an example 350 of reference signal measurement prior to the PO in the NR. Example 350 shows the signal from the base station to the NR UE in the time domain. In example 350, the NR UE may be in idle mode or inactive, such that the NR UE does not have an RRC connection with the base station. Therefore, the NR UE can wake up to monitor one or more POs. For example, similar to an LTE UE as described above, the NR UE can monitor the PDCCH to obtain a paging PDCCH message (e.g., encoded as DCI) indicating whether a paging PDSCH message has been scheduled. If the paging PDCCH message does not indicate that a paging PDSCH message has been scheduled, the NR UE can return to idle mode or inactive state. If the paging PDCCH message does indicate that a paging PDSCH message has been scheduled, the NR UE can receive and decode the paging PDSCH message and determine whether the NR UE is being paged. If the NR UE determines that it is being paged, it can reactivate or re-establish a pending RRC connection with the base station. If the NR UE determines that it is not being paged, it can return to idle mode or inactive state.
[0069] like Figure 3B As shown, the NR UE can measure synchronization signal blocks (SSBs) or other periodic signals from the base station because the base station does not transmit normally open reference signals. In example 350, the NR UE measures SSBs in time slots 352a, 352b, and 352c. By measuring SSBs, the NR UE can update the tracking loop and estimate the time delay, frequency offset, and / or other physical characteristics of signals from the base station before monitoring paging PDCCH messages in PO 354 (which may occupy one or more time slots). However, the NR UE may have to remain lightly sleepy for several radio frames before the upcoming PO 354 because SSBs may be narrow (e.g., transmitted with limited bandwidth and / or using only 20 resource blocks (RBs)) and / or sparse (e.g., transmitted only once every 20 ms, such as...). Figure 3B (As shown in the diagram). Therefore, compared to LTE UE, NR UE may consume more processing resources and battery power.
[0070] Some of the techniques and apparatus described herein enable an NR base station (e.g., base station 110) to configure one or more additional reference signals for an NR UE (e.g., UE 120). Thus, NR base station 110 can save processing and network resources by not transmitting normally open reference signals, while NR UE 120 can also save processing resources and battery life by maintaining deep sleep for an extended period before measuring one or more additional reference signals and subsequently monitoring for the upcoming point of failure (PO).
[0071] As indicated above, Figure 3A and Figure 3B Examples are provided. Other examples can be found in the reference. Figure 3A and Figure 3B The examples described are different.
[0072] Figure 4 This is a diagram illustrating an example 400 associated with a reference signal configured in an NR for an idle mode or inactive state UE, based on various aspects of this disclosure. Figure 4 As shown, Example 400 includes communication between NR base station 110 and NR UE 120. In some aspects, NR base station 110 and NR UE 120 may be included in a wireless network such as wireless network 100.
[0073] As shown in conjunction with reference numeral 405, the NR base station 110 can transmit an indication including a configuration for at least one reference signal, and the NR UE 120 can receive it. For example, the indication may include a data structure encoded with the configuration (e.g., a data structure defined in a 3GPP specification and / or another standard). In some aspects, the configuration may include one or more physical resources (e.g., frequency, beam, and / or other physical characteristics) associated with the at least one reference signal. Additionally or alternatively, the configuration may include one or more symbols, time slots, or other portions of the time domain in which at least one reference signal can be transmitted in the time domain.
[0074] In some aspects, at least one reference signal may include a tracking reference signal (TRS), a channel state information reference signal (CSI-RS), and / or another reference signal. In some aspects, an indication of the configuration may be included in a System Information Block (SIB) message. For example, the NR base station 110 may include this indication in an SIB1 message (e.g., an SIB1 message as defined in the 3GPP specification and / or another standard) and / or another SIB message scheduled by the SIB1 message (e.g., an SIB2 message as defined in the 3GPP specification and / or another standard).
[0075] As shown in conjunction with reference to reference numeral 410 in the accompanying drawings, NR UE 120 can enter an idle mode or an inactive state. For example, NR UE 120 can release its RRC connection with NR base station 110 to enter idle mode. Alternatively, NR UE 120 can suspend its RRC connection with NR base station 110 to enter an inactive state. In some aspects, NR UE 120 can select an NR cell including NR base station 110, decode SIB messages including configuration indications and / or other messages (as part of establishing an RRC connection with the NR base station), and transition to idle mode or an inactive state to conserve processing resources and battery power.
[0076] As shown in conjunction with reference numeral 415, the NR UE 120 can monitor at least one reference signal. For example, the NR UE 120 can monitor one or more resources included in the configuration for at least one reference signal. In some aspects, the NR UE 120 can use blind detection. For example, the NR base station 110 may not always transmit at least one reference signal; therefore, the NR UE 120 may have to monitor the at least one reference signal (e.g., using at least one antenna of the NR UE 120) and determine whether the at least one reference signal has been transmitted based at least in part on the result of the monitoring (e.g., based at least in part on the signal from the at least one antenna).
[0077] Alternatively or concurrently, the configuration for the at least one reference signal may include a time window. Therefore, the NR UE 120 can monitor the at least one reference signal within this time window. In some aspects, this time window may be associated with the next Point of Exploration (PO) of the NR UE 120. For example, the NR base station 110 may indicate a time window between 1 ms and 2 ms before the PO, a time window between 10 and 15 time slots before the PO, a time window between 144 and 168 symbols before the PO, and / or another time window in which the NR base station will transmit the at least one reference signal. Therefore, the NR UE 120 can monitor the at least one reference signal without using blind detection.
[0078] In some respects, the NR UE 120 may additionally employ blind detection to monitor the at least one reference signal outside of a time window. For example, the NR base station 110 may additionally transmit at least one reference signal outside of a time window, enabling the NR UE 120 to blindly detect the at least one reference signal.
[0079] In any of the aspects described above, NR UE 120 may use blind detection based at least in part on settings stored in the memory of NR UE 120. For example, NR UE 120 may be programmed (and / or otherwise pre-configured) to perform blind detection (e.g., outside of a time window and / or when NR base station 110 does not provide a time window). NR UE 120 may be pre-configured according to 3GPP specifications and / or another standard.
[0080] As shown in conjunction with reference numeral 420, the NR base station 110 can transmit at least one reference signal at least partially based on the indications of the configuration, and the NR UE 120 can receive it. For example, as described above, the NR UE 120 can detect at least one reference signal using blind detection and / or within a time window (e.g., as included in the configuration).
[0081] As shown in conjunction with reference numeral 425, the NR UE 120 can measure the at least one reference signal. For example, the NR UE 120 can update the tracking loop at least in part based on the at least one reference signal. Therefore, the NR UE 120 can determine the time delay, frequency offset, and / or other physical characteristics of the signal from the NR base station 110.
[0082] As shown in conjunction with reference numeral 430, NR base station 110 can send paging messages, and NR UE 120 can receive paging messages. For example, NR UE 120 can monitor the next PO associated with NR UE 120 at least in part based on measurements of the at least one reference signal (e.g., as described above in conjunction with reference numeral 425). Therefore, NR UE 120 can receive paging PDCCH messages in the next PO (which may occupy one or more time slots), and receive and decode corresponding paging PDSCH messages to determine whether NR UE 120 is being paged. If NR UE 120 determines that it is being paged, NR UE 120 can reactivate a pending RRC connection with NR base station 110, or re-establish an RRC connection with NR base station 110. If NR UE 120 determines that it is not being paged, NR UE 120 can return to idle mode or inactive state.
[0083] By using combination Figure 4 According to the described technology, NR base station 110 can configure one or more additional reference signals for NR UE 120. Therefore, NR base station 110 can save processing and network resources by not transmitting normally open reference signals, while NR UE 120 can also save processing resources and battery life by maintaining deep sleep for a longer period before measuring one or more additional reference signals and subsequently monitoring for the upcoming point of impact (PO).
[0084] As indicated above, Figure 4 Examples are provided. Other examples can be found in the reference. Figure 4 The examples described are different.
[0085] Figure 5 This is a diagram illustrating, according to various aspects of this disclosure, an example 500 related to activating and deactivating reference signals in the NR for a UE in idle mode or inactive state. Figure 5 As shown, Example 500 includes communication between NR base station 110 and NR UE 120. In some aspects, NR base station 110 and NR UE 120 may be included in a wireless network such as wireless network 100.
[0086] In some respects, the NR base station 110 can transmit an indication including a configuration for at least one reference signal, and the NR UE 120 can receive it (e.g., as combined above). Figure 4 (As described by reference numeral 405 in the accompanying drawings). In some aspects, this indication can also be used as an activation associated with the at least one reference signal. Therefore, the NR base station 110 can transmit at least one reference signal (e.g., in conjunction with the above) based at least in part on the indication of this configuration. Figure 4 (within the described time window).
[0087] As an alternative, as described below, the NR base station 110 may activate at least one reference signal separately from the indication of transmitting the configuration (e.g., using a separate message). Therefore, in some aspects, as indicated by reference numeral 505, the NR UE 120 may use blind detection to monitor at least one reference signal before receiving activation associated with it. For example, the NR base station 110 may not always transmit at least one reference signal; therefore, the NR UE 120 may have to monitor the at least one reference signal (e.g., using at least one antenna of the NR UE 120) and determine whether the at least one reference signal has been transmitted based at least in part on the result of this monitoring (e.g., at least in part on the signal from the at least one antenna). Alternatively, the NR UE 120 may avoid monitoring the at least one reference signal before receiving activation associated with it.
[0088] As shown in conjunction with reference numeral 510, the NR base station 110 can transmit an activation associated with at least one reference signal, and the NR UE 120 can receive it. For example, the activation may include a data structure (e.g., defined in a 3GPP specification and / or another standard) that encodes a bit indicating activation (e.g., by setting it to 1 or TRUE), an index associated with at least one reference signal, and / or another indicator activating at least one reference signal. In some aspects, the activation may be included in an SIB message (e.g., an SIB1 message as defined in a 3GPP specification and / or another standard, and / or another SIB message scheduled by an SIB1 message), a paging early indication (e.g., a signal indicating that the NR UE 120 will be paged during a PO and transmitted before that PO), a paging PDCCH message, and / or other similar messages.
[0089] In some respects, this activation can instruct that at least one reference signal be transmitted before the next PO of NR UE 120. For example, this activation can instruct NR base station 110 to transmit at least one reference signal within the time window of the next PO (e.g., as combined above). Figure 4 (As described). NR base station 110 may stop the transmission of the at least one reference signal after the next PO, making the activation temporary.
[0090] As an alternative, the activation could instruct that at least one reference signal be transmitted multiple times prior to multiple points of origin (POs) on the NR UE 120. For example, the activation could instruct the NR base station 110 to transmit at least one reference signal within a time window for each PO (e.g., as combined above). Figure 4 (As described). In some aspects, the activation may further indicate: the duration for which at least one reference signal will be transmitted (e.g., within a time window for all POs in the next 10ms, 11ms, etc.), and / or the number of POs for which at least one reference signal will be transmitted before it (e.g., within a time window for the next 5 POs, 6 POs, etc.). The NR base station 110 may stop the transmission of at least one reference signal after multiple POs, making the activation temporary.
[0091] Alternatively, the activation can instruct the NR base station 110 to periodically transmit at least one reference signal until deactivation. For example, the activation can instruct the NR base station 110 to transmit at least one reference signal every 5ms, every 6ms, etc. Additionally or alternatively, the activation can instruct the NR base station 110 to transmit at least one reference signal within a time window for each PO. Therefore, the activation can be persistent.
[0092] As shown in conjunction with reference numeral 515, the NR UE 120 can monitor at least one reference signal, at least in part, based on activation. For example, after receiving activation from the NR base station 110, the NR UE 120 can monitor one or more resources included in the configuration for the at least one reference signal.
[0093] In some respects, the NR UE 120 may be unable to receive or decode the activation. Therefore, in some respects, the NR UE 120 may determine whether to monitor at least one reference signal based at least in part on the current state of that reference signal. For example, if at least one reference signal has previously been deactivated or has never been activated, the NR UE 120 may continue not to monitor that at least one reference signal (or use blind detection). As another example, if at least one reference signal has previously been activated (e.g., temporarily, as described above), the NR UE 120 may continue to monitor that at least one reference signal.
[0094] Alternatively, when the NR UE 120 fails to receive or decode the activation, the NR UE may assume activation. Therefore, the NR UE 120 may monitor the at least one reference signal. Alternatively, when the NR UE 120 fails to receive or decode the activation, the NR UE may assume deactivation. Therefore, the NR UE 120 may not monitor the at least one reference signal.
[0095] As shown in conjunction with reference numeral 520, the NR base station 110 can transmit deactivation associated with at least one reference signal, and the NR UE 120 can receive it. For example, deactivation may include a data structure (e.g., defined in a 3GPP specification and / or another standard) that encodes bits indicating deactivation (e.g., by setting them to 0 or FALSE), an index associated with at least one reference signal, and / or another indicator for deactivating at least one reference signal. In some aspects, the deactivation may be included in SIB messages (e.g., SIB1 messages as defined in a 3GPP specification and / or another standard, and / or another SIB message scheduled by a SIB1 message), paging early indications, paging PDCCH messages, and / or other similar messages.
[0096] In some respects, the deactivation may indicate that at least one reference signal will not be transmitted before the next PO of NR UE 120. For example, the deactivation may indicate that NR base station 110 will not transmit at least one reference signal before the next PO. NR base station 110 may resume transmission of the at least one reference signal after the next PO, making the deactivation temporary.
[0097] Alternatively, the deactivation may indicate that at least one reference signal will not be transmitted multiple times before a plurality of points (POs) of the NR UE 120. For example, the deactivation may indicate that the NR base station 110 will not transmit at least one reference signal before the last of the plurality of POs. In some aspects, the deactivation may further indicate: the duration for which at least one reference signal will not be transmitted (e.g., no transmission for the next 10ms, 11ms, etc.), and / or the number of POs before which at least one reference signal will not be transmitted (e.g., no transmission until the last of the next 5 POs, 6 POs, etc.). The NR base station 110 may resume transmission of at least one reference signal after the plurality of POs, making the deactivation temporary.
[0098] As an alternative, deactivation can indicate that at least one reference signal will not be sent before activation. Therefore, deactivation can be persistent.
[0099] In some respects, the NR UE 120 may be unable to receive or decode deactivation. Therefore, in some respects, the NR UE 120 may determine whether to monitor at least one reference signal based at least partially on the current state of that reference signal. For example, if the at least one reference signal has previously been activated or not deactivated, the NR UE 120 may continue to monitor that at least one reference signal. As another example, if the at least one reference signal has previously been deactivated (e.g., temporarily, as described above), the NR UE 120 may continue not to monitor that at least one reference signal (or use blind detection).
[0100] Alternatively, when NR UE 120 fails to receive or decode deactivation, NR UE can assume deactivation. Therefore, NR UE 120 may not monitor at least one reference signal. Alternatively, when NR UE 120 fails to receive or decode deactivation, NR UE can assume activation. Therefore, NR UE 120 can monitor at least one reference signal.
[0101] In some respects, as illustrated by reference to reference numeral 525, the NR UE 120 may use blind detection to monitor at least one reference signal after receiving deactivation associated with at least one reference signal. For example, the NR base station 110 may sometimes transmit at least one reference signal, even after deactivation; therefore, the NR UE 120 may monitor at least one reference signal (e.g., using at least one antenna of the NR UE 120) and determine whether at least one reference signal has been transmitted based at least in part on the result of this monitoring (e.g., at least in part on the signal from at least one antenna). Alternatively, the NR UE 120 may avoid monitoring at least one reference signal after receiving deactivation associated with at least one reference signal.
[0102] By using combination Figure 5 According to the described technology, NR base station 110 can activate and deactivate one or more additional reference signals of NR UE 120. Therefore, NR base station 110 can save processing and network resources by not transmitting normally open reference signals, while NR UE 120 can also save processing resources and battery life by maintaining deep sleep for an extended period before measuring one or more additional reference signals and subsequently monitoring for the upcoming point of impact (PO).
[0103] As indicated above, Figure 5 Examples are provided. Other examples can be found in the reference. Figure 5 The examples described are different.
[0104] Figure 6 This is a diagram illustrating, according to various aspects of this disclosure, an example 600 associated with the transmission of reference signals in connection with paging an idle mode or inactive state UE in an NR. (See diagram for details.) Figure 6 As shown, Example 600 includes communication between NR base station 110 and NR UE 120. In some aspects, NR base station 110 and NR UE 120 may be included in a wireless network such as wireless network 100.
[0105] As shown in conjunction with reference numeral 605 in the accompanying drawings, the NR base station 110 can transmit an indication including a configuration for at least one reference signal, and the NR UE 120 can receive it (e.g., as shown above in conjunction with reference numeral 605). Figure 4(As described by reference numeral 405). In some aspects, the configuration for at least one reference signal may include: a time window associated with the next PO (e.g., the first PO as described below in conjunction with reference numeral 610) for the NR UE 120. For example, the NR base station 110 may indicate a time window between 1 ms and 2 ms before the PO, a time window between 10 and 15 time slots before the PO, a time window between 144 and 168 symbols before the PO, and / or another time window in which the NR base station 110 will transmit at least one reference signal. Furthermore, in some aspects, the NR UE 120 may enter an idle mode or an inactive state.
[0106] As shown in conjunction with reference to reference numeral 610 in the accompanying drawings, NR UE 120 can monitor the first PO. For example, NR UE 120 can monitor the paging PDCCH message in the first PO. If NR UE 120 receives a paging PDCCH, it can receive and decode the corresponding paging PDSCH message to determine whether NR UE 120 is being paged. If NR UE 120 determines that it is being paged, it can reactivate the pending RRC connection with NR base station 110 or re-establish the RRC connection with NR base station 110. If NR UE 120 determines that it is not being paged, it can return to idle mode or inactive state.
[0107] As shown in conjunction with reference numeral 615a, the NR base station 110 can transmit at least one reference signal between the first PO and the second PO, and the NR UE 120 can receive it (as described below in conjunction with reference numeral 625). Therefore, the NR UE 120 can measure at least one reference signal after the preceding PO (e.g., the first PO) and before the next PO (e.g., the second PO) for the NR UE 120.
[0108] As shown in conjunction with reference numeral 620, NR base station 110 can transmit a paging signal, and NR UE 120 can receive the paging signal. This paging signal can indicate that NR UE 120 will be paged at the next PO (e.g., a second PO as described below in conjunction with reference numeral 625). For example, the signal can be an early paging indication as defined in 3GPP specifications and / or another standard. Alternatively, the signal can be a PDCCH message (e.g., encoded as DCI) associated with the second PO.
[0109] Therefore, in some aspects, and as shown in conjunction with reference numeral 615b, the NR base station 110 can transmit the at least one reference signal after receiving a paging signal (as described above in conjunction with reference numeral 620) and before the next PO for the NR UE 120 (e.g., the second PO as described below in conjunction with reference numeral 625), which the NR UE 120 can then receive. Thus, the NR UE 120 can measure at least one reference signal after receiving a paging signal but before the PO associated with that paging signal.
[0110] As shown in conjunction with reference numeral 625 in the attached figure, NR UE 120 can monitor the second PO. For example, NR UE 120 can monitor the paging PDCCH message in the second PO. If NR UE 120 receives a paging PDCCH, it can receive and decode the corresponding paging PDSCH message to determine whether NR UE 120 is being paged. If NR UE 120 determines that it is being paged, it can reactivate the pending RRC connection with NR base station 110 or re-establish the RRC connection with NR base station 110. If NR UE 120 determines that it is not being paged, it can return to idle mode or inactive state.
[0111] As shown in conjunction with reference numeral 615c, the NR base station 110 can transmit at least one reference signal after receiving a paging signal (as described above in conjunction with reference numeral 620) and before one or more symbols in which an additional paging signal is expected (e.g., the additional paging signal is associated with another PO such as a third PO), and the NR UE 120 can receive it. Therefore, the NR UE 120 can measure at least one reference signal after receiving the paging signal but before receiving the additional paging signal.
[0112] In some respects, the NR UE 120 may additionally use blind detection to monitor at least one reference signal outside of one or more expected time windows (e.g., as described above, defined relative to the first PO and the second PO, defined relative to the paging signal and the second PO, and / or defined relative to both paging signals). For example, the NR base station 110 may additionally transmit at least one reference signal outside of one or more expected time windows, such that the NR UE 120 can blindly detect at least one reference signal.
[0113] The NR UE 120 can use blind detection, at least in part, based on settings stored in its memory. For example, the NR UE 120 can be programmed (and / or otherwise pre-configured) to perform blind detection (e.g., outside one or more expected time windows). The NR UE 120 can be pre-configured according to 3GPP specifications and / or another standard.
[0114] By using combination Figure 6 According to the described technology, NR base station 110 can send one or more additional reference signals before paging NR UE 120. Therefore, NR base station 110 can save processing and network resources by not sending normally open reference signals, while NR UE 120 can also save processing resources and battery life by maintaining deep sleep for a longer period before measuring one or more additional reference signals and subsequently monitoring the upcoming PO.
[0115] In some aspects, the NR base station 110 can determine whether to use an indication including a configuration for at least one reference signal as an activation associated with the at least one reference signal (e.g., as combined above). Figure 5 (as described), to provide activation and deactivation associated with the at least one reference signal (e.g., as described above in combination). Figure 5 As described), and / or at least partially based on stored settings (e.g., according to 3GPP specifications and / or another standard), transmit at least one reference signal (e.g., as in combination with) when paging NR UE 120. Figure 6 (As described). Alternatively, NR base station 110 may indicate to NRUE 120 whether to activate and deactivate at least one reference signal, or whether to transmit at least one reference signal in association with paging of NR UE 120. For example, NR base station 110 may send a message indicating whether to activate and deactivate at least one reference signal or whether to transmit at least one reference signal in association with paging of NR UE 120, and NRUE 120 may receive this message. This message may include a data structure (e.g., defined in 3GPP specifications and / or another standard) including code points and / or other similar indicators indicating whether to activate and deactivate at least one reference signal or whether to transmit at least one reference signal in association with paging of NR UE 120. In some aspects, this message may be included in SIB messages (e.g., SIB1 messages as defined in 3GPP specifications and / or another standard, and / or another SIB message scheduled by SIB1 messages), paging early indications, paging PDCCH messages, and / or other similar messages.
[0116] As indicated above, Figure 6Examples are provided. Other examples can be found in the reference. Figure 6 The examples described are different.
[0117] Figure 7 This is a diagram illustrating an example 700 associated with a configuration for removing a reference signal from the memory of a UE in idle mode or inactive state in an NR, based on various aspects of this disclosure. Figure 7 As shown, Example 700 includes communication between NR base station 110 and NR UE 120. In some aspects, NR base station 110 and NR UE 120 may be included in a wireless network such as wireless network 100.
[0118] In some respects, the NR base station 110 can transmit an indication including a configuration for at least one reference signal, and the NR UE 120 can receive it (e.g., as combined above). Figure 4 , 5 (as described in Figure 6). Therefore, in some aspects, as shown in conjunction with reference numeral 705a, NR base station 110 may transmit additional indications that do not include configuration for at least one reference signal, and NR UE 120 may receive them. For example, NR base station 110 may transmit new SIB messages (e.g., SIB1 messages as defined in 3GPP specifications and / or another standard, and / or another SIB message scheduled by SIB1 messages), new paging early indications (e.g., signals indicating that NR UE 120 will be paged during a PO and transmitted before that PO), new paging PDCCH messages, and / or another similar message that does not include configuration for at least one reference signal.
[0119] Alternatively or concurrently, as shown in conjunction with reference numeral 705b, the NR base station 110 may transmit additional instructions including a command to release a configuration for at least one reference signal, which the NR UE 120 may receive. For example, these instructions may include a data structure (e.g., defined in a 3GPP specification and / or another standard) that encodes bits indicating the instruction (e.g., by setting them to 1 or TRUE), an index associated with at least one reference signal, and / or another indicator that the NR UE 120 should release the configuration.
[0120] Alternatively or additionally, as shown in conjunction with reference numeral 705c, the NR UE 120 may determine that a timer associated with the configuration for at least one reference signal has expired. For example, the NR UE 120 may start the timer (e.g., as defined in 3GPP specifications and / or another standard, or configured by the NR base station 110, e.g., within the instruction for the configuration for at least one reference signal) after receiving an indication of the configuration for at least one reference signal. In some aspects, the NR UE 120 may further restart the timer when an additional indication from the NR base station 110 again includes the configuration and / or when the NR base station 110 sends an activation associated with at least one reference signal.
[0121] As shown in conjunction with reference numeral 710, NR UE 120 can remove a configuration for at least one reference signal from its memory. For example, NR UE 120 can mark one or more memory cells holding the configuration as available for new data. In some aspects, NR UE 120 can remove the configuration at least in part based on other instructions from NR base station 110 (e.g., as described above in conjunction with reference numeral 705a). Alternatively or additionally, NR UE 120 can remove the configuration at least in part based on instructions from NR base station 110 (e.g., as described above in conjunction with reference numeral 705b). Alternatively or additionally, NR UE 120 can remove the configuration at least in part based on the expiration of a timer (e.g., as described above in conjunction with reference numeral 705c).
[0122] In some respects, NR UE 120 can transition to a connected state with NR base station 110. For example, NR UE 120 can reactivate a pending RRC connection with NR base station 110, or re-establish an RRC connection with NR base station 110 (e.g., in response to being paged). Therefore, NR UE 120 can remove this configuration from its memory, at least in part, based on transitioning to a connected state.
[0123] Alternatively, NR UE 120 may establish an RRC connection with a new serving cell. For example, NR UE 120 may be mobile, causing it to leave the range associated with the serving cell including NR base station 110 and enter the range associated with a new serving cell. Therefore, NR UE 120 may remove this configuration from its memory, at least in part, based on the RRC connection with the new serving cell.
[0124] By using combination Figure 7The described technology allows the NR UE 120 to save processing resources and battery life by removing reference signal configurations that are no longer activated or otherwise useful to the NR UE 120 from memory.
[0125] As indicated above, Figure 7 Examples are provided. Other examples can be found in the reference. Figure 7 The examples described are different.

In some aspects, device 1000 includes a receiving component 1002 and a transmitting component 1004, which can communicate with each other (e.g., via one or more buses and / or one or more other components). As shown, device 1000 can use the receiving component 1002 and the transmitting component 1004 to communicate with another device 1006 (e.g., a UE, a base station, or another wireless communication device). As further shown in the figure, device 1000 may include one or more of a measurement component 1008, a monitoring component 1010, a memory controller 1012, or a determination component 1014, etc.
[0178] In some respects, device 1000 can be configured to perform the functions described herein. Figure 4-7 The one or more operations described herein. Alternatively or concurrently, the apparatus 1000 may be configured to perform one or more processes described herein, such as... Figure 8 The process 800 or a combination thereof. In some aspects, device 1000 and / or Figure 10 One or more components shown may include the combination described above. Figure 2 One or more components of the described UE. Alternatively or additionally, they may be combined with the above. Figure 2 Implemented in one or more of the described components Figure 10 One or more components are shown. Alternatively or separately, one or more of these components may be implemented, at least partially, as software stored in memory. For example, a component (or a portion thereof) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or processor to perform the function or operation of that component.
[0179] Receiver 1002 may receive communication (e.g., reference signals, control information, data communication, or combinations thereof) from device 1006. Receiver 1002 may provide the received communication to one or more other components of device 1000. In some aspects, receiver 1002 may perform signal processing on the received communication (e.g., filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, and other examples), and may provide the processed signal to one or more other components of device 1006. In some aspects, receiver 1002 may include the above-described combinations... Figure 2The described UE includes one or more antennas, demodulators, MIMO detectors, receiver processors, controllers / processors, memory, or combinations thereof.
[0180] Transmission component 1004 can send communications (e.g., reference signals, control information, data communications, or combinations thereof) to device 1006. In some aspects, one or more other components in device 1006 can generate communications and provide the generated communications to transmission component 1004 for transmission to device 1006. In some aspects, transmission component 1004 can perform signal processing on the generated communications (e.g., filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding, and other examples), and can send the processed signal to device 1006. In some aspects, transmission component 1004 can include the above-described combinations... Figure 2 The described UE includes one or more antennas, modulators, transmit MIMO processors, transmit processors, controllers / processors, memory, or combinations thereof. In some aspects, the transmit component 1004 may be co-located with the receive component 1002 in a transceiver.
[0181] In some aspects, receiving component 1002 can receive from device 1006 an instruction including a configuration for at least one reference signal. Additionally, when device 1000 is in idle mode or inactive, measuring component 1008 can measure the at least one reference signal at least partially based on the configuration instruction. In some aspects, measuring component 1008 may include the above-described combination... Figure 2 The described UE includes one or more antennas, demodulators, MIMO detectors, receiver processors, controllers / processors, memory, or combinations thereof.
[0182] In some aspects, the monitoring component 1010 may monitor the next paging opportunity associated with the device 1000 based at least in part on the measurement of the at least one reference signal by the measurement component 1008. In some aspects, the monitoring component 1010 may include the above-mentioned combination Figure 2 The described UE includes one or more antennas, demodulators, MIMO detectors, receiver processors, controllers / processors, memory, or combinations thereof.
[0183] In some aspects, receiving component 1002 can receive additional instructions from device 1006 that do not include the configuration for the at least one reference signal. Therefore, memory controller 1012 can remove the configuration for the at least one reference signal from the memory of device 1000, at least in part, based on the additional instructions.
[0184] Alternatively, receiving component 1002 may receive additional instructions from device 1006, which include an instruction to release the configuration for the at least one reference signal. Therefore, memory controller 1012 may remove the configuration for the at least one reference signal from the memory of device 1000, at least in part, based on the additional instructions.
[0185] Alternatively or concurrently, determining component 1014 may determine that a timer associated with the configuration for the at least one reference signal has expired. In some aspects, determining component 1014 may include the above-described combination of... Figure 2 The described UE includes a receiving processor, a transmitting processor, a controller / processor, a memory, or a combination thereof. Therefore, the memory controller 1012 can remove configurations for the at least one reference signal from the memory of the device 1000, at least in part, based on the expiration of a timer.
[0186] In some respects, receiving component 1002 and / or transmitting component 1004 can switch device 1000 to a connected state with device 1006. Therefore, memory controller 1012 can remove the configuration for the at least one reference signal from the memory of device 1000, at least in part, based on the switch to the connected state.
[0187] In some respects, the receiving component 1002 and / or the transmitting component 1004 can establish an RRC connection with the new serving cell. Therefore, the memory controller 1012 can remove the configuration for the at least one reference signal from the memory of the device 1000, at least in part, based on the RRC connection with the new serving cell.
[0188] In some respects, receiving component 1002 can receive activation associated with the at least one reference signal from device 1006. Therefore, measuring component 1008 can measure the at least one reference signal at least in part based on the activation received by receiving component 1002.
[0189] In some respects, the measurement component 1008 may use blind detection to measure the at least one reference signal before the receiving component 1002 receives activation.
[0190] Alternatively, receiving component 1002 may receive deactivation associated with the at least one reference signal from device 1006. Therefore, measuring component 1008 may avoid measuring the at least one reference signal, at least in part, based on this deactivation. Alternatively, measuring component 1008 may measure the at least one reference signal using blind detection after receiving the deactivation.
[0191] In any of the aspects described above, receiving component 1002 may receive from device 1006 a message indicating whether the at least one reference signal will be activated and deactivated, or whether the at least one reference signal will be transmitted in association with paging of device 1000.
