Two Downlink Control Information for Paging Early Indications to Address Additional Paging OccasionsTECHNICAL FIELD
[0001] Some example embodiments may generally relate to mobile or wireless telecommunication systems, such as 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) , 5th generation (5G) radio access technology (RAT) , new radio (NR) access technology, 6th generation (6G) RAT, and / or other communications systems. For example, certain example embodiments may relate to systems and / or methods for two downlink control information (DCI) for paging early indication (PEI) to address additional paging occasions (POs) .BACKGROUND
[0002] Examples of mobile or wireless telecommunication systems may include radio frequency (RF) 5G RAT, the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) , LTE Evolved UTRAN (E-UTRAN) , LTE-Advanced (LTE-A) , LTE-APro, NR access technology, and / or MulteFire Alliance. 5G wireless systems refer to the next generation (NG) of radio systems and network architecture. A 5G system is typically built on a 5G NR, but a 5G (or NG) network may also be built on E-UTRA radio. It is expected that NR can support service categories such as enhanced mobile broadband (eMBB) , ultra-reliable low-latency-communication (URLLC) , and massive machine-type communication (mMTC) . NR is expected to deliver extreme broadband, ultra-robust, low-latency connectivity, and massive networking to support the Internet of Things (IoT) . The next generation radio access network (NG-RAN) represents the radio access network (RAN) for 5G, which may provide radio access for NR, LTE, and LTE-A. It is noted that the nodes in 5G providing radio access functionality to a user equipment (e.g., similar to the Node B in UTRAN or the Evolved Node B (eNB) in LTE) may be referred to as next-generation Node B (gNB) when built on NR radio, and may be referred to as next-generation eNB (NG-eNB) when built on E-UTRA radio.
[0003] 3GPP 6G is intended to build upon the advantages and breakthroughs of previous cellular technologies, with multi-RAT spectrum sharing (MRSS) enabling smooth transitions from 5G to 6G. 6G carrier aggregation (CA) / may further improve on network capacity and coverage, while dual-connectivity can provide support for non-collocated 6G areas. Using next generation mobile broadband, (NextGenMBB) , user equipment may experience data rates around 500 Mbps. 6G may also incorporate fixed wireless access (FWA) to improve traffic for fixed locations, such as homes, offices, and businesses. FWA can leverage terahertz and millimeter-wave bands to deliver ultra-fast data speeds, potentially up to 100 Gbps, especially with multiple input multiple output (MIMO) antennas.
[0004] Moreover, 3GPP 6G is expected to incorporate artificial intelligence / machine learning (AI / ML) technologies to perform network automation and enable self-optimizing networks (SONs) . For example, AI / ML may monitor network usage, conditions, and traffic in real-time, and automatically adjust network parameters such as interference mitigation, spectrum management, and load balancing, thereby providing faster failure recoveries and reducing network congestion.SUMMARY

[0023] It will be readily understood that the components of certain example embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of some example embodiments of systems, methods, apparatuses, and computer program products for two DCI for PEI to address additional POs is not intended to limit the scope of certain example embodiments, but is instead representative of selected example embodiments.
[0024] In 3GPP 5G, paging enables a network to alert user equipment (UE) about incoming data, messages, or calls when the UE is in radio resource control (RRC) IDLE or INACTIVE mode. This process enables the UE to remain in low-power states, waking only when there is relevant information from the network, thereby saving battery life. The paging cycle defines the interval at which the UE checks for paging messages, with longer cycles favoring energy savings and shorter cycles enabling faster notification. Within each cycle, specific paging frames (PF) are designated for potential paging messages.
[0025] To optimize this process further, 5G may group UEs into distinct groups based on their unique identifiers (i.e., UE ID) . This distribution may distribute the paging load, thereby preventing a large number of UEs from being paged in a single occasion and thus attempting to access the network simultaneously. By hashing the unique identifiers, each UE is assigned to a specific group with its designated PF and specific paging occasion (PO) . Within these PF, each group listens for paging messages at its PO, allowing UEs to remain in low-power mode and wake up only as needed (when the UE ID is listed in the paging record of the paging message) .
[0026] Additionally, 5G includes paging early indications (PEI) , where an early signal notifies UEs about upcoming PO, allowing the UE to monitor next PO, reducing the time they spend actively listening for a message. This early indication further enhances power efficiency by use of subgrouping per PO. For example, UEs belonging to 1 PO may be divided into 4 subgroups to further reduce the false paging alarm rate (i.e., UE detects the paging DCI, but does not find its UE ID in the paging record) .
[0027] The 3GPP Re-19 paging adaptation may reduce the number of distributed paging transmissions by grouping the paging occasions of different UEs closely together in time. As shown in FIG. 1, this clustering allows for longer cell sleeping periods, and may enable the network to assign fewer distributed random-access occasions for UE responses. Additionally, it allows the network to concentrate reference signal transmissions near these clustered paging occasions, ensuring the UE is prepared to receive the paging.
[0028] The implementation may involve extending the PF interval, creating more spacing between PFs compared to the traditional interval. Each extended PF can accommodate more POs, maintaining the overall paging capacity. The current maximum PF interval is 16 radio frames (160 ms) while the release 19 enhancement will allow at least 32 radio frames. Such doubling of the PF interval may require that the number of POs per PF is increased proportionally, such as also doubled (e.g., from 4 POs per PF to 8 POs per PF) .
[0029] In addition, clustering paging occasions does not affect paging latency, as it only modifies the distribution of POs within the existing paging cycle for Rel-19 UEs, leaving the cycle duration unchanged. This approach may enable legacy UEs to continue operating under the original paging scheme, ensuring backwards compatibility and preventing the need for "Release 19 UE-only" cells.
[0030] In 3GPP, the period of PF intervals may be increased to at least 32 radio frames, while the number of POs per PF may be increased from the current 4 to at least 8. Therefore, the PEI would need to address up to 8 POs for the same PF, which is not currently supported.
[0031] A single PEI (e.g., a single DCI of DCI Format2_7) may be configured to address up to 4 POs of the same PF, or up to 8 POs of two distinct but consecutive PFs. Furthermore, the maximum DCI size may be 43 bits. This size may not be increased to address 8 POs in 1 PF because it will be undecodable by the legacy UEs. Therefore, the single PEI of rel-17 may be unable to accommodate the paging indications for the additional up to 4 POs introduced by Rel-19 paging enhancements.
[0032] One solution may be to multiplex the paging indication of legacy UEs and Rel-19 UEs in the same PEI (e.g., by mapping the additional Rel-19 POs to the legacy POs) , but this may increase a false paging alarm. An alternative approach would be to use a distinct PEI for Rel-19, which may include up to 8 POs per PF and up to 4 subgroups per PO. However, it is undesirable for the network to transmit two PEI DCIs (i.e., PEI-r17 to address legacy UEs and PEI-r19 to address r19 UEs of the same PF, as it would increase the network energy consumption) .
[0033] Certain example embodiments described herein may have various benefits and / or advantages to overcome the disadvantages described above. For example, certain example embodiments may use two PEI DCIs while reducing the need to always send two PEI DCIs, thereby improving network energy savings. Thus, certain example embodiments discussed below are directed to improvements in computer-related technology.
[0034] In some example embodiments, a second PEI for UE may be conditional based on certain conditions so that the network does not always need to transmit two PEIs a first PEI for legacy UEs, and a second PEI for Rel-19 UE, thereby reducing energy consumption without increasing the false paging rate.
[0035] FIG. 3 illustrates an example of a flow diagram of a method 300 that may be performed by a UE, such as UE 820 illustrated in FIG. 8, according to various example embodiments.
[0036] At step 301, the method may include receiving a PEI configuration from a network entity, such as NE 810 illustrated in FIG. 8.
[0037] For example, UE (e.g., R19-capable) may receive (e.g., via system information block (SIB) 1 or RRC signalling) a PEI configuration (e.g., in the paging configuration) dedicated to Rel-19 paging adaptation (e.g., where more than 4 POs per PF can be set) . The PEI configuration may indicate whether the UE should monitor a single PEI or two PEIs (e.g., where the second PEI may be configured conditionally to an indication in the first PEI) , and may further indicate the monitoring occasions (MO) associated with the PEI (s) to be monitored.
[0038] In various example embodiments, the PEI configuration may indicate a single PEI, where the PEI to be monitored by the UE may be the same PEI monitored by legacy UEs (e.g., PEI-r17) . Thus, the PEI bits for legacy POs and additional Rel-19 POs may be multiplexed in the same DCI 2_7. The UE may monitor for a DCI_Format_2_7 in the associated PEI monitoring occasion (s) .
[0039] In certain example embodiments, the PEI configuration may indicate a single PEI, where the PEI to be monitored by the UE is a distinct PEI from the one monitored by legacy UEs (e.g., PEI-r19) . Thus, the PEI bits for legacy POs and additional Rel-19 POs may not be multiplexed in the same DCI 2_7. The UE may monitor for a DCI_Format_2_7 in the respective PEI monitoring occasion (s) . Moreover, the PEI-r19 may be differentiated from PEI-r17 based on the radio network temporary identifier (RNTI) with which the PEI is scrambled or by dedicated MO (s) associated to the PEI monitoring. The use of a dedicated RNTI and associated scrambling may enable the network to transmit the two PEIs in the same time instance (e.g. same symbol (s) / slot) multiplexing them in the frequent domain in order to reduce the energy consumption on the network for PEI transmissions. In other embodiments, the two PEIs may be separated in the time domain, using different MOs. As an example, the two PEIs may be in the same time resources if separated using different RNTIs. They can also be separated in the frequency domain. However, if the legacy UE monitors across a wide bandwidth, it may not be sufficient to separate only in frequency; hence, the RNTI differentiation may also be needed.
[0040] In some example embodiments, the PEI configuration may indicate two-PEIs, wherein the PEI bits for legacy POs and additional Rel-19 POs may be multiplexed in the same DCI 2_7. The R19 UE may monitor for two distinct DCI_Format_2_7 in the associated PEI monitoring occasion (s) . However, the monitoring of the second PEI may be conditional based on information in the first PEI.
[0041] In various example embodiments, the network may indicate either option (e.g., based on the load of legacy UEs in the cell) . If the number of legacy UEs to be paged in a certain period of time is below a first threshold, the PEI configuration may indicate a single PEI that is applicable to both legacy and R19 UEs. Alternatively, if the number of legacy UEs to be paged exceeds a second threshold, the PEI configuration may indicate the need to monitor two PEIs, where the second PEI is to be monitored by the R19 UEs, and is for conditional monitoring based on information in the first PEI.
[0042] At step 302, the method may further include monitoring and receiving a first PEI based on the PEI configuration.
[0043] For example, for two PEIs, the first PEI (i.e., PEI-r17) may be associated with the first MO, and the second MO is configured only for R19 UEs to monitor the second PEI (PEI-r19) . Both legacy UEs and R19 UEs may monitor the first MO for the first DCI 2_7, where the first DCI carries the paging indication of legacy POs (i.e., the first 4 POs in the PF) to both UE types (legacy UEs and R19 UEs) . The second PEI in the second MO may carry the paging indication of the additional POs in the PF only to R19 UEs or of all POs of the R19 UEs.
[0044] Some example embodiments may include conditional monitoring of the second PEI. For example, a second-PEI-indication may be present in the first PEI for the R19 UE to determine whether it should monitor the second PEI or not. As an example, the second PEI indication may be a spare bit in the first DCI that indicates to the R19 UEs whether or not the second MO shall be monitored by R19 UEs (e.g., via the second-PEI-indication bit, as shown in FIG. 4) .
[0045] In various example embodiments, the second-PEI-indication may apply only to the additional POs (e.g., PO#5-8) . In this case, the R19 UE associated to a legacy PO (PO#1-4) may be configured to read the paging indication always in the first PEI.
[0046] In certain example embodiments, the indication may apply to both legacy POs (e.g., PO#1-4) and the additional POs (e.g., PO#5-8) . In this case, the R19 UE associated to a legacy PO (PO#1-4) may be configured to determine whether to read its paging indication in the first or second PEI based on a second-PEI-indication.
[0047] As an example, if the second-PEI-indicafion bit=1, then the R19 UE may monitor the second MO with second DCI. Otherwise, the R19 UE may read the paging indication in the first PEI, where the additional POs can be multiplexed with legacy POs, as shown in FIG. 4. This may provide energy savings at the network and the UE. For example, the network may avoid transmitting the second PEI in case the false paging rate can be minimized by using just the first PEI (e.g., if false paging rate is not increased for legacy UEs when multiplexing R19) . In contrast, the network may use the second PEI if paging load increases and would like to protect the legacy UEs from increased false paging. In addition, the UE may reduce energy usage if it can avoid monitoring for a second PEI.
[0048] In certain example embodiments with a single PEI, the UE may monitor for a single DCI_Format_2_7 in the associated PEI monitoring occasion (s) , and read the UE-specific PEI bit (e.g., based on UE’s PF, PO and subgroup) as per legacy mechanism.
[0049] At step 303, the method may include determining whether the second PEI indication indicates the first PEI (e.g., ‘0’ ) . If the second PEI indication indicates the first PEI, then at step 304, the method may include reading the paging indication in the first PEI.
[0050] If the second PEI indication does not indicate the first PEI at step 303, then at step 305, the method may include determining whether the second PEI indication indicates the second PEI (e.g., ‘1’ ) , and if it does, then at step 306, the method may further include monitoring for a second PEI.
[0051] FIG. 5 illustrates an example of a flow diagram of a method 500 that may be performed by a UE, such as UE 820 illustrated in FIG. 8, according to various example embodiments. Steps 501-502 and 505-508 may be similar to steps 301-306, respectively, as discussed above.
[0052] At step 503, the method may further include determine whether a second PEI indication indicates no paging (e.g., ‘00’ ) , and if yes, then at step 504, skipping monitoring of the next MO associated to the PO of the UE.
[0053] For example, the second-PEI-indication bit (e.g., one of the spare bits in the first DCI) may indicate to the R19 UEs whether or not the second MO shall be monitored by R19 UEs. If second-PEI-indication bit=1, the R19 UE may monitor the second MO with second DCI; otherwise, the R19 UE may skip the monitoring of the second MO with second DCI, as illustrated in FIG. 6. If bit=0, the network may also utilize the resources configured for the second MO for the other transmission purpose, ifneeded.
[0054] In various example embodiments, one additional spare bit in the first PEI may be used by the network to indicate that the UE stops monitoring PEI monitoring and assumes no paging (e.g., ‘00’ ) ; that the UE shall monitor the first PEI (PEI-r17) (e.g., ‘01’ ) ; that the UE shall monitor the second PEI (PEI-r19) (e.g., ‘10’ ) ; and / or that the EU stops PEI monitoring and assumes paging for all UE (e.g., if there is SI change or Earthquake and Tsunami Warning System (ETWS) ) .
[0055] FIG. 7 illustrates an example of a flow diagram of a method 700 that may be performed by a UE, such as UE 820 illustrated in FIG. 8, according to various example embodiments.
[0056] At step 701, the method may include receiving, from a network entity, a PEI configuration comprising information related to one or more PEIs.
[0057] At step 702, the method may further include receiving, based on the PEI configuration, a first PEI of the one or more PEIs.
[0058] At step 703, the method may further include determining, based on the first PEI, to perform one of the following actions: monitoring for a second PEI; skipping monitoring for the second PEI; reading a paging indication in the first PEI; or skipping paging monitoring for a next paging occasion.
[0059] In certain example embodiments, the second PEI may be received based upon the PEI configuration.
[0060] In some example embodiments, the PEI configuration may indicate whether the apparatus should monitor one PEI or multiple PEIs.
[0061] In various example embodiments, the first PEI may indicate whether the UE shall read the paging indication in the first PEI or monitor for the second PEI, and the method may further include determining to further perform one of the following based on the first PEI: monitoring for the second PEI; or reading the paging indication in the first PEI.
[0062] In certain example embodiments, the first PEI may instruct the UE to read the paging indication in the first PEI, and the method may further include reading the paging indication in the first PEI.
[0063] In some example embodiments, the paging indication in the first PEI may be multiplexed with a paging indication of another UE having a different paging occasion.
[0064] In various example embodiments, the paging indication for the another UE may be in a third PEI, and the first PEI and the third PEI may be scrambled with different RNTIs.
[0065] In certain example embodiments, the second PEI may be scrambled with a RNTI different from a RNTI of the first PEI.
[0066] In some example embodiments, the method may further include determining the paging indication in the first PEI based on the paging occasion of the UE.
[0067] In various example embodiments, the first PEI may include two bits, and the method may further include determining the action based on the value of the first PEI.
[0068] In certain example embodiments, the method may further include monitoring a second PEI indicating whether the UE shall monitor a paging occasion.
[0069] In some example embodiments, the method may further include, upon determining to perform the at least one paging operation comprising stop paging monitoring, skipping monitoring of a next paging occasion.
[0070] In various example embodiments, the second PEI may be dedicated to a subset of paging occasions of a paging frame, wherein the subset comprises a determined number of last paging occasions in the paging frame. For example, this may include POs which are not used / monitored / supported by the UEs only supporting the first PEI / being prior to Rel-19.
[0071] In certain example embodiments, the method may further include determining that the second PEI indicates reading a paging indication, and reading a paging indication associated with a related paging occasion based on the PEI configuration.

The term “non-transitory, ” as used herein, may correspond to a limitation of the medium itself (i.e., tangible, not a signal) as opposed to a limitation on data storage persistency (e.g., random access memory (RAM) vs. read-only memory (ROM) ) . A hard disk drive (HDD) , random access memory (RAM) , flash memory, or other suitable memory may be used. The memories may be combined on a single integrated circuit as the processor, or may be separate from the one or more processors. Furthermore, the computer program instructions stored in the memory, and which may be processed by the processors, may be any suitable form of computer program code, for example, a compiled or interpreted computer program written in any suitable programming language.

The device may have many antennas, such as an array of antennas configured for multiple input multiple output (MIMO) communications, or multiple antennas for multiple RATs. Other configurations of these devices, for example, may be provided. Transceivers 813 and 823 may be a transmitter, a receiver, both a transmitter and a receiver, or a unit or device that may be configured both for transmission and reception.
[0080] The memory and the computer program instructions may be configured, with the processor for the particular device, to cause a hardware apparatus, such as UE, to perform any of the processes described above (i.e., FIGs. 3-7) . Therefore, in certain example embodiments, a non-transitory computer-readable medium may be encoded with computer instructions that, when executed in hardware, perform a process such as one of the processes described herein. Alternatively, certain example embodiments may be performed entirely in hardware.
[0081] In certain example embodiments, an apparatus may include circuitry configured to perform any of the processes or functions illustrated in FIGs. 3-7. As used in this application, the term “circuitry” may refer to one or more or all of the following: (a) hardware-only circuit implementations (such as implementations in only analog and / or digital circuitry) , (b) combinations of hardware circuits and software, such as (as applicable) : (i) a combination of analog and / or digital hardware circuit (s) with software / firmware and (ii) any portions of hardware processor (s) with software (including digital signal processor (s) ) , software, and memory (ies) that work together to cause an apparatus, such as a mobile phone or server, to perform various functions) , and (c) hardware circuit (s) and or processor (s) , such as a microprocessor (s) or a portion of a microprocessor (s) , that requires software (e.g., firmware) for operation, but the software may not be present when it is not needed for operation.

As a further example, as used in this application, the term circuitry also covers an implementation of merely a hardware circuit or processor (or multiple processors) or portion of a hardware circuit or processor and its (or their) accompanying software and / or firmware. The term circuitry also covers, for example and if applicable to the particular claim element, a baseband integrated circuit or processor integrated circuit for a mobile device or a similar integrated circuit in server, a cellular network device, or other computing or network device.
[0082] FIG. 9 illustrates an example of a 5G / 6G network and system architecture according to certain example embodiments. Shown are multiple network functions that may be implemented as software operating as part of a network device or dedicated hardware, as a network device itself or dedicated hardware, or as a virtual function operating as a network device or dedicated hardware.
