[0018] As those skilled in the art will understand, aspects of the embodiments can be embodied as a system, apparatus, method, or program product. Accordingly, the embodiments can take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, microcode, etc.), or an embodiment combining software and hardware aspects, which in this document are generally referred to as "circuitry", "module", or "system". In addition, the embodiments can take the form of a program product embodied in one or more computer-readable storage devices storing machine-readable code, computer-readable code, and / or program code hereinafter referred to as "code". The storage device can be tangible, non-transitory, and / or non-transmission. The storage device may not embody a signal. In certain embodiments, the storage device merely takes the form of a signal for accessing the code.

[0019] Certain functional units described in this specification may be labeled as modules for the purpose of more particularly emphasizing their implementation independence. For example, a module can be implemented as a hardware circuit including custom very large scale integration ("VLSI") circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module can also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, etc.

[0020] A module can also be implemented with code and / or software to be executed by various types of processors. The identified code module can include, for example, one or more physical or logical blocks of executable code, which can be organized, for example, as objects, procedures, or functions. However, the executable files of the identified module do not need to be physically located together, but may include disparate instructions stored in different locations, which, when logically connected together, include the module and achieve the purpose of the module.

[0021] In fact, a code module can be a single instruction or many instructions, and can even be distributed over several different code segments, different programs, and across several memory devices. Similarly, in this document, operational data can be identified and illustrated within a module, and can be embodied in any suitable form and organized within any suitable type of data structure. The operational data can be collected as a single data set, or can be distributed at different locations, including on different computer-readable storage devices. In the case where a module or a portion of a module is implemented in software, the software portion is stored on one or more computer-readable storage devices.

[0022] Any combination of one or more computer-readable media can be utilized. The computer-readable media can be a computer-readable storage medium. The computer-readable storage medium can be a storage device that stores the code. The storage device can be, by way of example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, holographic, micro-mechanical, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.

[0023] More specific examples (a non-exhaustive list) of storage devices will include the following: an electrical connection having one or more wires, a portable computer disk, a hard disk, a random access memory ("RAM"), a read-only memory ("ROM"), an erasable programmable read-only memory ("EPROM" or flash memory), a portable compact disc read-only memory ("CD-ROM"), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer-readable storage medium can be any tangible medium that can contain or store a program for use by or in connection with an instruction execution system, apparatus, or device.

[0024] The code for performing the operations of the embodiments can be any number of lines and can be written in any combination of one or more programming languages including object-oriented programming languages such as Python, Ruby, Java, Smalltalk, C++, and the like, and traditional procedural programming languages such as the "C" programming language, and / or machine languages such as assembly language. The code can execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer, or entirely on a remote computer or server. In the latter case, the remote computer can be connected to the user's computer through any type of network connection, including a local area network ("LAN") or a wide area network ("WAN"), or can be connected to an external computer (e.g., through the Internet using an Internet service provider).

[0025] References in this specification to "one embodiment", "an embodiment", or similar language mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, unless otherwise explicitly stated, the phrases "in one embodiment", "in an embodiment", and similar language throughout the specification may, but do not necessarily, all refer to the same embodiment, but rather mean "one or more but not all embodiments". Unless otherwise explicitly stated, the terms "comprises", "comprising", "has", and their variants mean "including but not limited to". Unless otherwise explicitly stated, a list of items listed does not imply that any or all of the items are mutually exclusive. Unless otherwise explicitly stated, the terms "a", "an", and "the" also refer to "one or more".

[0026] In addition, the features, structures, or characteristics of the described embodiments can be combined in any suitable manner. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of the embodiments. However, those skilled in the relevant art will recognize that the embodiments can be practiced without one or more of the specific details, or by using other methods, components, materials, etc. In other cases, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring some aspects of the embodiments.

[0031] It should also be noted that in some alternative embodiments, the functions noted in the blocks may not occur in the order noted in the figures. For example, two blocks shown in succession may in fact be executed substantially simultaneously, or the blocks may sometimes be executed in the reverse order, depending on the functions involved. Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more blocks or portions thereof of the figures shown.

[0032] Although various arrow types and line types may be employed in the flowchart and / or block diagram, it should be understood that they do not limit the scope of the corresponding embodiments. In fact, some arrows or other connectors may be used only to indicate the logical flow of the depicted embodiments. For example, an arrow may indicate a waiting or monitoring period of unspecified duration between enumerated steps of the depicted embodiment. It will also be noted that each block of the block diagram and / or flowchart, and combinations of blocks in the block diagram and / or flowchart, can be implemented by a system based on dedicated hardware that performs a particular function or operation, or by a combination of dedicated hardware and code.

[0041] Figure 2 Depict an embodiment of an apparatus 200 that can be used to determine paging occasion resources. The apparatus 200 includes an embodiment of the remote unit 102. Additionally, the remote unit 102 can include a processor 202, a memory 204, an input device 206, a display 208, a transmitter 210, and a receiver 212. In some embodiments, the input device 206 and the display 208 are combined into a single device, such as a touch screen. In certain embodiments, the remote unit 102 may not include any input device 206 and / or display 208. In various embodiments, the remote unit 102 can include one or more of the processor 202, the memory 204, the transmitter 210, and the receiver 212, and may not include the input device 206 and / or the display 208.

In such an embodiment, in response to not receiving information indicating the use of a control resource set different from the first control resource set, the first control resource set is the same as the second control resource set. The processor 202 is communicatively coupled to the memory 204, the input device 206, the display 208, the transmitter 210, and the receiver 212.

[0043] In one embodiment, the memory 204 is a computer-readable storage medium. In some embodiments, the memory 204 includes a volatile computer storage medium. For example, the memory 204 may include RAM, which includes dynamic RAM (“DRAM”), synchronous dynamic RAM (“SDRAM”), and / or static RAM (“SRAM”). In some embodiments, the memory 204 includes a non-volatile computer storage medium. For example, the memory 204 may include a hard disk drive, a flash memory, or any other suitable non-volatile computer storage device. In some embodiments, the memory 204 includes both a volatile computer storage medium and a non-volatile computer storage medium. In some embodiments, the memory 204 also stores program code and related data, such as an operating system or other controller algorithms operating on the remote unit 102.

[0044] In one embodiment, the input device 206 may include any known computer input device, including a touchpad, buttons, a keyboard, a stylus, a microphone, etc. In some embodiments, the input device 206 may be integrated with the display 208, for example, as a touchscreen or a similar touch-sensitive display.

In some embodiments, the input device 206 includes two or more different devices such as a keyboard and a touchpad.

[0045] In one embodiment, the display 208 may include any known electronically controllable display or display device. The display 208 may be designed to output visual signals, auditory signals, and / or tactile signals. In some embodiments, the display 208 includes an electronic display capable of outputting visual data to a user.

[0047] The transmitter 210 is used to provide an UL communication signal to the network unit 104, and the receiver 212 is used to receive a DL communication signal from the network unit 104, as described herein. Although only one transmitter 210 and one receiver 212 are illustrated, the remote unit 102 may have any suitable number of transmitters 210 and receivers 212. The transmitter 210 and the receiver 212 may be any suitable type of transmitter and receiver. In one embodiment, the transmitter 210 and the receiver 212 may be part of a transceiver.

[0048] Figure 3 Another embodiment of an apparatus 300 that may be used to determine paging occasion resources is depicted. The apparatus 300 includes an embodiment of the network unit 104. Additionally, the network unit 104 may include a processor 302, a memory 304, an input device 306, a display 308, a transmitter 310, and a receiver 312. It can be understood that the processor 302, the memory 304, the input device 306, the display 308, the transmitter 310, and the receiver 312 may be substantially similar to the processor 202, the memory 204, the input device 206, the display 208, the transmitter 210, and the receiver 212 of the remote unit 102, respectively.

[0049] In some embodiments, the transmitter 310 may be used to send configuration information of the CORESET and / or paging occasions. In some embodiments, the processor 302 may: determine a first control resource set for sending system information; and determine to use a second control resource set to determine paging occasions. In such an embodiment, in response to the transmitter 310 not sending information indicating the use of a control resource set different from the first control resource set, the first control resource set is the same as the second control resource set. Although only one transmitter 310 and one receiver 312 are illustrated, the network unit 104 may have any suitable number of transmitters 310 and receivers 312. The transmitter 310 and the receiver 312 may be any suitable type of transmitter and receiver. In one embodiment, the transmitter 310 and the receiver 312 may be part of a transceiver.

[0050] In some embodiments, a network entity (e.g., gNB) may use the paging procedure to send paging information to a UE in the idle mode, or to notify the UE of SI change, ETWS notification, CMAS notification, EAB parameter modification, or to perform an inter-frequency reallocation procedure.

[0051] In various configurations, such as in a 5G new RAT that supports both single-beam and multi-beam operations simultaneously, a single paging message may be sent once or multiple times through different TX beams of the gNB. This may be because in a multi-beam based system operation, each UE can receive at most a few gNB TX beams, and it may be difficult for the gNB to obtain the latest information about the appropriate TX beams of idle-mode UEs. In addition, some messages such as SI change notification and emergency warning notification during the paging procedure may be delivered to all UEs in the cell.

[0052] In a single-beam based paging procedure, such as in LTE, a PO may be defined as a subframe (e.g., 1 millisecond), in which there may be a PDCCH carrying DCI to schedule a PDSCH carrying paging and / or notification information, and may be scrambled by a P-RNTI. In addition, as used herein, a PF is a radio frame that may contain one or more POs.

[0053] In various embodiments, in a multi-beam based paging procedure, the gNB may generate multiple PDSCHs and / or PDCCHs on different TX beams for transmission using a single paging (or notification) message, and may multiplex multiple paging PDSCHs and / or PDCCHs with other channels and signals. In some embodiments, paging PDCCH beam scanning in the time domain may be supported separately from the SS block.

[0054] In some embodiments, a method for configuring paging occasions may allow for flexible allocation of radio resources for paging occasions with no or very limited signaling overhead in the basic system information by reusing signaling indicating a CORESET for scheduling a PDSCH carrying RMSI (e.g., basic system information other than the MIB). In various embodiments, allowing for multi-subframe or multi-slot delays for transmitting paging PDSCH relative to the transmission of paging DCI may enable effective packing of beam-scanned channels and may result in efficient resource utilization.

[0055] As used herein, an antenna port may be defined such that a channel through which a symbol on one antenna port is transmitted can be inferred from a channel through which another symbol on the same antenna port is transmitted.

[0056] Further, two antenna ports are considered QCL if the large-scale properties of a channel through which a symbol on one antenna port is transmitted can be inferred from a channel through which a symbol on another antenna port is transmitted. The large-scale properties may include one or more of the following: delay spread, Doppler spread, Doppler shift, average gain, average delay, and / or spatial RX parameters. Also, two antenna ports may be QCL with respect to a subset of the large-scale properties. The spatial RX parameters may include one or more of the following: AoA, dominant AoA, average AoA, angular spread, PAS of AoA, average AoD, PAS of AoD, transmit channel correlation, receive channel correlation, transmit beamforming, receive beamforming, spatial channel correlation, and / or other parameters.

[0057] In some embodiments, a UE in the RRC_IDLE or RRC_INACTIVE state can monitor paging using one paging occasion per DRX cycle. In such embodiments, a paging occasion can be a time interval during which its gNB transmits channels and / or signals related to paging. In various embodiments, the length of the DRX cycle and the number of paging occasions within the DRX cycle can be configured by a network entity (e.g., gNB, base station) and provided to the UE via a system information message. Additionally, in some embodiments, the UE can be configured with a UE-specific DRX cycle length via dedicated signaling. If multiple paging occasions are configured within a DRX cycle, the paging of the UE can be distributed over the multiple paging occasions based on the UE ID. In some embodiments, a paging occasion can include multiple time slots (e.g., OFDM symbols) to allow the network entity to transmit paging using different downlink TX beams in each time slot or to repeat paging using the same TX beam over multiple time slots. In some embodiments, the number of time slots for a paging occasion can be provided via system information. In one example, a paging message can include up to 16 UE IDs (e.g., S-TMSI - a temporary UE identifier provided by a core network entity that uniquely identifies the UE in the tracking area in the EPC).

[0058] In various embodiments, a network entity can transmit one or more SS blocks (also referred to as SS / PBCH blocks) per cycle. In such embodiments, each SS block can be associated with a DL TX antenna port (or DL TX beam) and can carry the PSS and / or SSS and additionally the PBCH. In one example, an SS block can include four consecutive OFDM symbols in the order of PSS, PBCH, SSS, and PBCH symbols. In some embodiments, an SS burst set (or SS set) can include one or more SS blocks and can be transmitted periodically. In some embodiments, the maximum number of SS blocks per SS burst set and the time position within the SS burst set period can be predefined for each frequency band and can depend on the SCS of the synchronization signal. In some embodiments, the time position of the actually transmitted SS blocks can be indicated to the UE to assist the UE in connected mode and / or idle mode to perform measurements and to receive DL data and / or control channels at an appropriate rate matching around the transmitted SS blocks.

[0059] In one embodiment, the MIB in the PBCH may include some basic minimum system information that is obtained by the UE to access the cell. In various embodiments, the RMSI may be included in SystemInformationBlockType1 (“SIB1”) and / or SystemInformationBlockType2 (“SIB2”). In some embodiments, SIB1 may use a fixed scheduling (e.g., fixed radio frame number, time slot number, and / or sub - frame number) with a predetermined periodicity (e.g., 80 milliseconds), and may be repeated within the predetermined periodicity. In some embodiments, the scheduling periodicity of SIB2 and / or other SIBs may be indicated in SIB1, and SIB2 may be transmitted within a periodically occurring time - domain window (e.g., referred to as the SI window) using dynamic scheduling. In certain embodiments, the CORESET of the PDCCH for scheduling the PDSCH carrying SIB1 and / or SIB2 may also be configured periodically according to the scheduling periodicity of SIB1 and / or SIB2.

[0060] In some embodiments, such as in multi - beam - based operations, each CORESET or each search space of the CORESET of the PDCCH for the scheduling information of the PDSCH carrying the RMSI (e.g., possible PDCCH candidate positions within the CORESET) may be associated with one or more SS blocks. That is, the UE may use the same RX beam to receive the CORESET (or the search space of the CORESET) and the associated one or more SS blocks, and may assume QCL between the CORESET and the associated SS blocks based on propagation delay (e.g., average delay, delay spread) and / or Doppler parameters (Doppler spread and / or Doppler shift). In addition, the PBCH in the associated SS block may include an indication of the time and frequency resources of the CORESET for RMSI transmission.

[0061] In one embodiment, the paging occasion includes a set of CORESETs or a set of search spaces corresponding to a complete gNB beam sweep, and the UE can determine at least one CORESET (or search space) in each of one or more sets of CORESETs (or search spaces) for one or more paging occasions based on information about at least one CORESET in the set of CORESETs configured for RMSI. In some embodiments, the UE can determine at least one CORESET in the set of CORESETs configured for RMSI transmission by decoding the PBCH. In various embodiments, the UE can obtain the information necessary to determine at least one CORESET (or search space) in each of one or more sets of CORESETs (or search spaces) for one or more paging occasions by decoding the PDSCH carrying the RMSI (e.g., SIB1 and / or SIB2). In some embodiments, the monitoring periodicity of the paging DCI and / or PDCCH or paging search space can be different from the periodicity of the CORESET (e.g., an integer multiple or a sub-integer (1 / k, k = integer) multiple of the periodicity of the CORESET).

[0062] In some embodiments, the UE can receive an indication of one or more time and / or frequency offsets and / or distances from the set of CORESETs for RMSI to the set of CORESETs for one or more paging occasions in the RMSI, and can determine at least one CORESET for each paging occasion by applying the indicated time and / or frequency offset and / or distance to at least one CORESET of the RMSI. In such an embodiment, a time and / or frequency offset and / or distance can be defined between two spatially QCL CORESETs, one for RMSI and the other for the paging occasion (e.g., the antenna ports of one CORESET for RMSI and one CORESET for paging are spatially QCL). In various embodiments, the UE can apply a predetermined and / or known time and / or frequency offset and / or distance to at least one CORESET for RMSI and thereby determine at least one CORESET for each paging occasion.

[0063] In some embodiments, the UE may calculate its own paging frames and paging opportunities within the paging frames based on its UE ID and DRX cycle length. In some embodiments, depending on network operations (e.g., due to very low UE activity, temporarily cutting off the broadcast channel and / or signal in certain spatial directions), the actual PDCCH transmission for the delivery of paging DCI may occur on a portion or all of the CORESETs at a given paging opportunity. In various embodiments, the UE may monitor several CORESETs associated with several suitable gNB TX beams within its own paging opportunity. In one embodiment, the CORESET for paging DCI is spatially QCL with the SS / PBCH block. In another embodiment, the CORESET for paging DCI and the CORESET for RMSI delivery are spatially QCL, and they are associated with the antenna ports of two or more SS / PBCH blocks (e.g., joint transmission of two SS / PBCH block beams).

[0064] In various embodiments, the network entity may configure the CORESET for paging DCI to be the same as a superset or subset of the CORESET for DCI scheduling the RMSI message. In one embodiment, the monitoring period of the paging DCI / PDCCH or the paging search space may be different from the period of the CORESET (e.g., an integer multiple or sub-integer (1 / k, k = integer) multiple of the period of the CORESET). In some embodiments, the set of CORESETs for paging DCI (e.g., the paging opportunity) may need to be configured with a shorter periodicity than the set of CORESETs for DCI scheduling the RMSI message to accommodate an LTE-like paging capacity (e.g., 6400 UEs paged per second). In one embodiment, the set of CORESETs for paging DCI is configured in each radio frame, and the set of CORESETs for RMSI delivery is configured in every other radio frame. In another embodiment, both the CORESET for paging DCI and the CORESET for RMSI delivery are configured in every other radio frame with the same radio frame offset, sharing one set of CORESETs in the radio frame for paging and RMSI delivery, and using the other set of CORESETs in the radio frame for paging DCI, as Figure 4 shown. Figure 4 The figure shows that the network entity configures 4 POs in the paging radio frame, where 2 POs are time and frequency multiplexed with the SS / PBCH block. In addition, one PO is used for both paging and RMSI delivery. The REs within the CORESET not used for PDCCH transmission can be used for the transmission of other channels or signals, e.g., PDSCH via dynamic scheduling and indication.

[0065] Figure 4 is a schematic block diagram illustrating an embodiment of a timing diagram 400 depicting four paging opportunities. The first paging opportunity (“PO1”), the second paging opportunity (“PO2”), the third paging opportunity (“PO3”), and the fourth paging opportunity (“PO4”) are illustrated during a time period 402. The first paging opportunity may include a CORESET for RMS IDCI and paging DCI, and the second paging opportunity, the third paging opportunity, and the fourth paging opportunity may include a CORESET for paging DCI. Additionally, a PDSCH is illustrated, which may carry a paging message for the first paging opportunity. The time period 402 may include a paging frame 404 (e.g., a paging radio frame). Additionally, the paging frame may be divided into a first half-frame 406 (e.g., 5 ms) and a second half-frame 408 (e.g., 5 ms). The arrow from the first paging opportunity to the PDSCH indicates a paging message that may correspond to the paging DCI in the paging opportunity.

[0066] In some embodiments, the paging DCI may schedule the PDSCH carrying the paging message with a one or more sub-frame or slot delay between the PDCCH carrying the paging DCI and the PDSCH carrying the paging message. In various embodiments, the flexible time and frequency resource allocation of the PDSCH carrying the paging message increases the radio resource utilization efficiency by effectively multiplexing the PDSCH carrying the paging message with other PDSCHs carrying user data or other paging opportunities. In Figure 4 it is shown that the PDSCH transmitted with a first gNB TX beam and carrying a paging message for the first paging opportunity is frequency-domain multiplexed with a CORESET for the third paging opportunity associated with the first gNB TX beam in the same OFDM symbol with a 5 ms transmission delay. Since analog beamforming or analog-digital hybrid beamforming at the gNB may limit the flexible frequency-domain multiplexing of multiple channels and / or signals transmitted through different beams, the multiplexing of the paging PDSCH with the corresponding paging opportunity or other paging opportunities within one or more OFDM symbols is beneficial for the efficient packing of beam-scanned channels. In Figure 4 embodiments, since the first paging opportunity and the second paging opportunity are multiplexed with SS / PBCH blocks, fewer resource elements are available for the transmission of the paging PDSCH in the OFDM symbol having a CORESET for the first paging opportunity or the second paging opportunity. In such embodiments, a multi-sub-frame or multi-slot transmission delay for the paging PDSCH may allow the gNB to efficiently pack the beam-scanned channels. In some embodiments, to limit the DCI signaling overhead, a set of allowed sub-frame or slot-level delay values may be predefined or configured considering the allowed paging opportunity configuration.

[0067] It can be understood that transmitting the PDSCH carrying the paging message through multiple beams on the same time and frequency resources will reduce the paging overhead. Therefore, the UE may not assume spatial QCL between the CORESET for paging DCI and the DM RS of the corresponding PDSCH carrying the paging message.
