[0002] A wireless communications system may include one or multiple network communication devices, such as base stations, which may be otherwise known as an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. Each network communication devices, such as a base station may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE) , or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) . Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G) ) .
[0003] In 5G new radio (NR) systems, paging enables the network to reach UEs with paging messages, such as when downlink data arrives. Paging is also used to notify UEs of updates, such as system information modifications, or to deliver signals for emergency alerts, such as the earthquake and tsunami warning system (ETWS) / commercial mobile alert system (CMAS) indications, through short messages. Enhancements on paging are still needed.SUMMARY

[0055] Aspects of the present disclosure are described in the context of a wireless communications system.
[0056] FIG. 1A illustrates an example of a wireless communications system 100 that supports paging adaptation in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 102 (also referred to as network equipment (NE) ) , one or more UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0057] The one or more network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a radio access network (RAN) , a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.
[0058] A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0059] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0060] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in FIG. 1A. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in FIG. 1A. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0061] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0062] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0063] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN Intelligent Controller (RIC) (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, or any combination thereof.
[0064] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0065] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160.
[0066] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0067] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0068] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0069] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0070] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0071] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0072] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0073] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0074] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0075] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0076] In 5G NR systems, for UEs in RRC_IDLE / RRC_INACTIVE state, a UE may only monitor only one paging occasion (PO) of one paging frame (PF) per discontinuous reception (DRX) cycle (i.e., paging cycle) . A PF is one radio frame, which is associated with one or multiple PO (s) . A PO is a set of PDCCH monitoring occasions (PMOs) for transmitting paging DCI. The number of PMOs of a PO is equal to the number of actually transmitted SSBs determined according to parameter ssb-PositionsInBurst in SIB1, which defines the actually transmitted SSBs of the network. The k-th PMO in the PO corresponds to the k-th actually transmitted SSB indicated by ssb-PositionsInBurst. The same beam is assumed for the paging DCI transmission in the PMO and the associated SSB. The PF / PO for UE monitoring is determined based on the UE identity (ID) . Depending on configuration, a paging cycle may contain more than one PF, so from the perspective of a base station (BS) , it may need to wake more than once during one paging cycle to transmit paging DCIs and paging messages.
[0077] FIG. 1B illustrates an example of a paging frame structure. In the example in FIG. 1B, one paging cycle contains two PFs and one PF contains (or is associated with) one PO. The parameter ssb-PositionsInBurst is configured as “01100110” , which means SSBs {1, 2, 5, 6} are the actually transmitted SSBs. A PO has four paging monitoring occasions (PMOs) {0, 1, 2, 3} , which are associated with SSBs {1, 2, 5, 6} respectively. It should be understood that although one paging cycle contains two PFs in the example of FIG. 1B, a UE may monitor only one PO in each paging cycle.
[0078] A paging DCI is transmitted in each PMO of a PO, using DCI format 1_0 with cyclic redundancy check (CRC) scrambled by paging radio network temporary identity (P-RNTI) . The paging DCI contains following information fields: Short Message Indicator, Short Messages, Frequency domain resource assignment, Time domain resource assignment, VRB-to-PRB mapping, Modulation and coding scheme, TB scaling, and TRS availability indication. Table 1 shows the explanation of the Short Message Indicator in a paging DCI in related solutions.
[0079] Table 1 Explanation of Short Message Indicator in Related Solutions
[0080] As shown in Table 1, if only the scheduling information for Paging (e.g., time and frequency resource allocation, modulation and coding scheme, etc) , and TRS availability indication if trs-ResourceSetConfig is configured, are carried in the paging DCI (i.e., the bit field value of the Short Message Indicator is 01) , the bit field Short Messages is reserved. If only the short message, and TRS availability indication if trs-ResourceSetConfig is configured, are carried in the paging DCI (i.e., the bit field value of the Short Message Indicator is 10) , the following bit fields are reserved: Frequency domain resource assignment, Time domain resource assignment, VRB-to-PRB mapping, Modulation and coding scheme, and TB scaling. The field Short Message Indicator occupies 2 bits. The field Short Messages occupies 8 bits. The field TRS availability indication may occupy 0, 1, 2, 3, 4, 5, or 6 bits. The number of bits for the field 'TRS availability indication’ may be determined based on the paging configuration. The paging DCI may have (6 -M) reserved bits, where the value of M is the number of bits for the field 'TRS availability indication'.
[0081] To reduce UE power consumption on paging monitoring, a paging early indication (PEI) was introduced. PEI is transmitted in a PEI occasion (PEI-O) and can be associated with up to two PFs (and correspondingly associated with one or multiple POs) . PEI may be transmitted before paging and is used to indicate whether the UE needs to monitor the associated PO. If the UE does not detect PEI on the PEI-O or the PEI does not indicate the subgroup, that the UE belongs to, to monitor the associated PO, the UE is not required to monitor the associated PO. Then, the UE may stay in a longer sleep mode and thus power consumption for paging monitoring can be reduced.
[0082] FIG. 1C illustrates an example of a paging scheme involving PEI. As shown in FIG. 1C, a PEI-O is associated with one PF which includes one PO. The radio frame containing PEI-O is determined by a parameter pei-FrameOffset, which is equal to four in the example of FIG. 1C. In the determined frame, a PEI-O contains four PDCCH monitoring occasions, the same PEI is transmitted in each PEI-O using a specific beam.
[0083] A specific DCI, i.e., DCI format 2_7, is defined as the PEI. The DCI format 2_7 contains a paging indication field and a TRS availability indication field. The paging indication field occupies bit (s) , where is the number of paging occasions configured by higher layer parameter po-NumPerPEI, is the number of subgroups of a paging occasion configured by higher layer parameter subgroupsNumPerPO. Each bit in the paging indication field indicates one UE subgroup of a PO. The TRS availability indication field may occupy 1, 2, 3, 4, 5, or 6 bits, where the number of bits is equal to one plus the highest value of all the indBitID (s) provided by the trs-ResourceSetConfig if configured; or 0 bits otherwise.
[0084] The size of DCI format 2_7 is indicated by the higher layer parameter payloadSizeDCI-2-7. The number of information bits in DCI format 2_7 shall be equal to or less than the payload size of DCI format 2_7. If the number of information bits in DCI format 2_7 is less than the size of DCI format 2_7, the remaining bits are reserved.
[0085] To reduce network power consumption on paging transmission, it is proposed to introduce R19 dedicated PFs / POs, while allowing legacy UEs and R19 UEs to co-exist in the same PF / PO. Besides, for R19 UEs, the number of POs in a PF extends to 8 or every larger value, so that more POs are allocated in a time consecutive manner. This provides more opportunity for gNB to stay in sleep mode and achieves energy saving. R19 UEs or Release-19 UEs may refer to UEs with advanced capabilities or supporting advanced technologies (e.g., supporting paging adaptation) , while legacy UEs may refer to UEs not supporting paging adaptation. It should be understood that the terminologies “R19 UEs” and “R19 PFs / POs” are merely for illustration. Other terminologies are also possible.
[0086] FIG. 1D illustrates an example of a paging frame structure for paging different types of UEs. As shown in FIG. 1D, legacy PFs / POs and R19 PFs / POs are separately configured. R19 UEs and legacy UEs may share a same PF. In the example in FIG. 1D, in the shared PF, the POs for R19 UEs and POs for legacy UEs are not overlapped. In other words, POs are not shared by R19 UEs and legacy UEs.
[0087] In some scenarios, it is possible that at least some POs are shared by legacy UEs and R19 UEs. Enhancements on paging, in particular regarding how paging messages are scheduled for each type of UEs, are needed. One embodiment is to introduce a dedicated paging DCI for scheduling R19 paging. The dedicated paging DCI may be scrambled a specific RNTI, which is different with the legacy P-RNTI and is configured by the base station. However, in a PMO, a paging DCI might need to occupy a large amount of physical resources (i.e., CCEs) to achieve robust performance. Therefore, it might be hard for a CORESET (i.e., CORESET#0) to accommodate two paging DCIs. In some implementations, the paging DCI may be shared between legacy UEs and R19 UEs. This also means that paging messages of legacy UEs and R19 UEs may be multiplexed and scheduled by a same (legacy) paging DCI. This may facilitate reducing the signaling overhead and avoiding PDCCH blocking.
[0088] Embodiments of the present disclosure provide a solution for paging adaptation. In an aspect of the solution, if a UE of a first type supporting paging adaptation receives a paging DCI containing at least one of a short message indicator or an additional indicator which is indicative of presence of scheduling information for paging at least one UE of the first type in the paging DCI, the UE monitors a paging message based on the paging DCI. In this way, UEs supporting paging adaptation may be individually paged without impacting the other UEs supporting paging adaptation. Impacts for each type of UEs (i.e., legacy UEs and R19 UEs) are reduced. For example, when paging messages of only one UE type are to be scheduled, the other type of UEs can be silent, i.e., the other type of UEs do not need to detect the paging message. This is beneficial in terms of UE power saving.
[0089] Reference is now made to FIG. 2, which illustrates an example signaling chart of a communication process that supports paging adaptation in accordance with some example embodiments of the present disclosure. For the purpose of discussion, the process 200 will be described with reference to FIG. 1A. The process 200 may involve the UE 104 and the base station 102. It is to be understood that the steps and the order of the steps in FIG. 2 are merely for illustration, and not for limitation. It is to be understood that process 200 may further include additional blocks not shown and / or omit some shown blocks, and the scope of the present disclosure is not limited in this regard.
[0090] In the process 200, the base station 102 transmits (202) a paging DCI 204 to the UE 104. Accordingly, the UE 104 receives (206) the paging DCI 204 from the base station 102. The paging DCI 204 includes at least one of a short message indicator or an additional indicator. The UE 104 is of a first type supporting paging adaptation. The at least one of the short message indicator or the additional indicator is indicative of presence of scheduling information for paging at least one UE of the first type in the paging DCI 204. Then, the base station 102 transmits (208) a paging message 210 to the UE 104 based on the paging DCI 204. Accordingly, the UE 104 receives (212) the paging message 210 from the base station 102 based on the paging DCI 204. In this way, the paging DCI may be shared by UEs supporting paging adaptation and UEs not supporting paging adaptation and UEs supporting paging adaptation may be paged without impacting UEs not supporting paging adaptation. Thus, the signaling overhead and UE power consumption may be reduced.
[0091] In some embodiments, a first state of the short message indicator may be indicative of presence of the scheduling information for paging at least one UE of the first type in the paging DCI 204. For example, if a UE receives a paging DCI comprising a short message indicator with a bit value “00” , the UE may be aware that scheduling information for paging R19 UE (s) is present in the paging DCI. Upon receiving such paging DCI, a R19 UE may detect a paging message based on the scheduling information, while a legacy UE may stay in a sleep mode.
[0092] In some embodiments, a second state of the short message indicator may be indicative of presence of scheduling information for paging at least one UE of a second type not supporting paging adaptation in the paging DCI 204. In the second state of the short message indicator, the scheduling information for paging at least one UE of the first type is absent in the paging DCI 204. For example, if a UE receives a paging DCI comprising a short message indicator with a bit value “01” , the UE may be aware that scheduling information for paging legacy UE (s) is present in the paging DCI. Upon receiving such paging DCI, a legacy UE may continue to detect a paging message based on the scheduling information, while a R19 UE may stay in a sleep mode.
[0093] In some embodiments, a third state of the short message indicator may be indicative of presence of short message in the paging DCI 204. In the third state of the short message indicator, the scheduling information for paging at least one UE of the first type and scheduling information for paging at least one UE of a second type not supporting paging adaptation are absent in the paging DCI 204. For example, if a UE receives a paging DCI comprising a short message indicator with a bit value “10” , the UE may be aware that the paging DCI contains a short message but does not contain scheduling information for paging. Upon receiving such paging DCI, both legacy UE (s) and R19 UE (s) may detect the short message in the paging DCI, but will not detect a paging message since there is no scheduling information for paging.
[0094] In some embodiments, a fourth state of the short message indicator may be indicative of presence of short message and at least one of the scheduling information for paging at least one UE of the first type or scheduling information for paging at least one UE of a second type not supporting paging adaptation in the paging DCI 204. For example, if a UE receives a paging DCI comprising a short message indicator with a bit value “11” , the UE may be aware that the paging DCI contains a short message as well as scheduling information for paging either legacy UE (s) or R19 UE (s) or both. Upon receiving such paging DCI, both legacy UE (s) and R19 UE (s) may detect the short message in the paging DCI. In some implementations, upon receiving such paging DCI, both legacy UE (s) and R19 UE (s) may detect a paging message based on the scheduling information for paging.
[0095] The base station may set the Short Message Indicator to different states depending on whether to schedule R19 paging, legacy paging, or paging for both type of UEs. The behaviour of R19 UEs and legacy UEs may be same of different for each indicated state. Table 2 shows a first example explanation of the Short Message Indicator in a paging DCI according to some embodiments of the present disclosure.
[0096] Table 2 Explanation of Short Message Indicator in First Example
[0097] As shown in Table 2, if only paging for R19 UEs are to be scheduled, while no legacy paging, then the base station can set the short message indicator as “00” . Upon receive this indication, legacy UEs will ignore this paging DCI since state “00” is a reserved state for legacy UEs. R19 UEs will get the scheduling information from the DCI and may continue to detect paging message according to the scheduling information. In other words, if R19 UEs detect state “00” of the short message indicator, the scheduling information in the paging DCI is valid for R19 UEs, and is used for scheduling paging message for R19 UEs.
[0098] If only paging for legacy UEs are to be scheduled, while no R19 paging, then the base station can set the short message indication as “01” . Upon receiving this indication, legacy UEs may continue to detect paging according to the scheduling information, while R19 UEs will not detect paging since there are no paging messages.
[0099] If only short messages are present in the DCI, then the base station can set the short message indicator as “10” . Upon receive this indication, both legacy UEs and R19 UEs will detect the short messages and there are no paging messages.
[0100] If both short messages and paging for either legacy UEs or R19 UEs or both types of UEs are to be scheduled, then the base station can set the short message indicator as “11” . Upon receiving this indication, both legacy UEs and R19 UEs will detect the short message and paging messages, according to scheduling information in the DCI.
[0101] In this way, it is possible to have shared paging DCI between legacy UEs and R19 UEs while reducing impact for each type of UEs (legacy UEs and R19 UEs) when paging messages of only one UE type are to be scheduled. The state “00” in the short message indicator (i.e., the reserved state as in Table 1) is used to indicate that only scheduling information for R19 paging is present in the DCI. The UE power consumption may be reduced.
[0102] In some embodiments, the additional indicator may include one bit in the paging DCI 204. For example, one bit among the 6-M reserved bits in the paging DCI, if exist (depending on the trs-ResourceSetConfig) may be used, on its own or in combination with the short message indicator, to indicate whether R19 paging message are to be scheduled.
[0103] In some embodiments, a third state of the short message indicator may be indicative of presence of short message in the paging DCI. In the third state of the short message indicator, scheduling information for paging at least one UE of a second type not supporting paging adaptation is absent in the paging DCI 204. The additional indicator may be indicative of presence of the scheduling information for paging at least one UE of the first type in the paging DCI 204. In an example, if a UE receives a paging DCI comprising a short message indicator with a bit value “10” , the UE may be aware that the paging DCI contains a short message but does not contain scheduling information for paging legacy UE (s) . Upon receiving such paging DCI, both legacy UE (s) and R19 UE(s) may detect the short message in the paging DCI and legacy UE (s) will not detect a paging message. In addition, if the additional indicator in the paging DCI has a bit value “1”, the R19 UE (s) may be aware that scheduling information for paging R19 UE (s) is present in the paging DCI and may detect a paging massage accordingly.
[0104] In some embodiments, a fourth state of the short message indicator may be indicative of presence of short message and scheduling information for paging at least one UE of a second type not supporting paging adaptation in the paging DCI. The additional indicator may be indicative of presence of the scheduling information for paging at least one UE of the first type in the paging DCI 204. In an example, if a UE receives a paging DCI comprising a short message indicator with a bit value “11” , the UE may be aware that the paging DCI contains a short message and scheduling information for paging legacy UE (s) . Upon receiving such paging DCI, both legacy UE (s) and R19 UE(s) may detect the short message in the paging DCI and legacy UE (s) will further detect a paging message. In addition, if the additional indicator in the paging DCI has a bit value “1” , the R19 UE (s) may be aware that scheduling information for paging R19 UE(s) is present in the paging DCI and may detect a paging massage accordingly.
[0105] The base station may set the Short Message Indicator and an additional indicator to different states depending on whether to schedule R19 paging, legacy paging, or paging for both type of UEs. The behaviour of R19 UEs and legacy UEs may be same of different for each indicated state. Table 3 shows a second example explanation of the Short Message Indicator and an additional bit in a paging DCI according to some embodiments of the present disclosure.
[0106] Table 3 Explanation of Short Message Indicator and Additional Bit in Second Example
[0107] As shown in Table 3, the reserved state “00” of the short message indicator and an additional bit are used to indicate the presence of scheduling information for R19 paging. The state “00” of the short message indicator indicates that only scheduling information for R19 paging is present in the DCI. For legacy UEs, the state “00” of the short message indicator is reserved. The state “01” of the short message indicator indicates that only scheduling information for legacy paging is present in the DCI. The state “10” of the short message indicator indicates that short messages are present in the DCI. Whether there are paging message for R19 UEs depends on indication in the additional bit. The state “11” of the short message indicator indicates that both scheduling information for legacy paging and short messages are present in the DCI. Whether there are paging message for R19 UEs depends on indication in the additional bit.
[0108] In this way, it is possible to have shared paging DCI between legacy UEs and R19 UEs while avoiding impact for each type of UEs (legacy UEs and R19 UEs) when paging messages of only one UE type are to be scheduled. R19 UEs and legacy UEs do not need to perform unnecessary paging monitoring. The UE power consumption may be further reduced.
[0109] In some embodiments, the additional indicator may be indicative of presence of the scheduling information for paging at least one UE of the first type in the paging DCI 204. In other words, the presence of scheduling information for paging R19 UE (s) may be indicated by the additional indicator in the paging DCI. The short message indicator in the paging DCI may be used to indicate the presence of scheduling information for paging legacy UE (s) and the presence of short message.
[0110] The base station may set the Short Message Indicator and an additional indicator to different states depending on whether to schedule R19 paging, legacy paging, or paging for both type of UEs. The behaviour of R19 UEs and legacy UEs may be same of different for each indicated state. Table 4-1 and Table 4--2 shows a third example explanation of the Short Message Indicator and an additional bit in a paging DCI according to some embodiments of the present disclosure.
[0111] Table 4-1 Explanation of Short Message Indicator in Third Example
[0112] Table 4-2 Explanation of Additional Bit in Third Example
[0113] As shown in Table 4-1 and Table 4-2, the short message indicator is used to indicate the presence of short messages and scheduling information for legacy paging, while the additional bit is used to indicate the presence of scheduling information for R19 paging.
[0114] In this way, it is possible to have shared paging DCI between legacy UEs and R19 UEs while avoiding impact for each type of UEs (legacy UEs and R19 UEs) when paging messages of only one UE type are to be scheduled. R19 UEs and legacy UEs do not need to perform unnecessary paging monitoring. The UE power consumption may be further reduced.
[0115] With the example embodiments of the present disclosures, behaviours of R19 UEs are indicated based on the indication in the shared paging DCI between legacy UEs and R19 UEs. Impact for each type of UEs (legacy UEs and R19 UEs) is reduced / avoided when paging messages of only one UE type are to be scheduled. There is no impact on legacy UE behaviour, i.e., legacy UEs will not perform unnecessary paging monitoring.
[0116] Another aspect of sharing paging DCI between legacy UEs and R19 UEs is how SSBs and PMOs are associated for R19 UEs when legacy UEs and R19 UEs co-exist in a same PF but not in a same PO. FIG. 3A illustrates an example of a paging frame structure including full overlapped paging occasions for different types of UEs in accordance with some example embodiments of the present disclosure. As shown in FIG. 3A, PO#0 for legacy UEs and PO#0 for R19 UEs fully overlap with each other. FIG. 3B illustrates an example of a paging frame structure including partial overlapped paging occasions for different types of UEs in accordance with some example embodiments of the present disclosure. As shown in FIG. 3B, two PMOs of PO#0 for legacy UEs and two PMOs of PO#0 for R19 UEs overlap.
[0117] In some embodiments, a first plurality of PMOs in a first paging occasion (PO) for UEs of the first type may include at least one PMO overlapped with at least one PMO among a second plurality of PMOs in a second PO for UEs of the second type. The at least one overlapped PMO among the first plurality of PMOs is mapped to at least one synchronization signal and physical broadcast channel (PBCH) block (SSB) among a plurality of indicated SSBs based on a SSB to PMO association of the at least one overlapped PMO among the second plurality of PMOs. In other words, if POs of the two types of UEs are at least partially overlapped, the beam correspondence of overlapped PMO with SSBs for R19 UEs should be aligned with legacy UEs.
[0118] In some embodiments, the first plurality of PMOs may further include at least one PMO non-overlapped with the second plurality of PMOs, and the at least one non-overlapped PMO among the first plurality of PMOs is sequentially mapped to at least one remaining SSB among the plurality of indicated SSBs. In other words, when PMOs of an R19 PO partially overlap with PMOs of a legacy PO, firstly, for the overlapped PMOs of an R19 PO, the SSB to PMO association follows legacy. This guarantees no impacts to legacy UEs. Then, the non-associated SSBs are sequentially mapped to the non-overlapped PMOs of an R19 PO. In this way, the SSBs and PMOs are associated for R19 UEs when PMOs of an R19 PO partially overlap with PMOs of a legacy PO.
[0119] As shown in the examples in FIGs. 3A and 3B, ssb-PositionsInBurst =0110011, which means SSB {1, 2, 5, 6} are the actually transmitted SSBs. Legacy PO#0 contains four PMOs {0, 1, 2, 3} , which are associated with SSB {1, 2, 5, 6} , respectively.
[0120] In the example in FIG. 3A, PO#0 for legacy UEs and PO#0 for R19 UEs fully overlap with each other. Accordingly, R19 PMOs {0, 1, 2, 3} are associated with SSB {1, 2, 5, 6} , respectively.
[0121] In the example in FIG. 3B, R19 PO#0 partially overlaps with legacy PO#0. R19 PMO {0, 1} of PO#0 overlap with legacy PMO {2, 3} of PO#0, while PMO {2, 3} do not have overlapped PMOs. Accordingly, R19 PMO {0, 1} are associated with SSB {5, 6} , respectively. R19 PMO {2, 3} are associated with SSB {1, 2} , respectively.
[0122] Besides, with dedicated POs configured for R19 UEs, it is possible to allow dynamically adaptation of paging configurations, e.g., dynamically change PO number (even = 0) for R19 UEs according to the number of UEs that are accessing the network. A further aspect is how to dynamically change PO number for R19 UEs. In order to reduce signalling overhead and standard impact, some embodiments of the present disclosure propose to use an existing DCI to indicate the paging adaptation. Given that paging is mostly target for RRC idle / inactive UEs, the candidate is then either paging DCI, PEI, or DCI for system info. (e.g., SIB1) scheduling.
[0123] In some embodiments, the UE 104 may receive a first PEI associated with a first paging frame (PF) from the base station 102. The first PEI may be indicative of a configuration of at least one additional PF or at least one additional PO. The UE 104 may receive, from the base station 102, a second PEI associated with the at least one additional PF or the at least one additional PO based on the first PEI. In some embodiments, a size the second PEI may be associated with the configuration of at least one additional PF or at least one additional PO in the first PEI.
[0124] In some embodiments, the first PEI is indicative of the configuration of the at least one additional PF. The configuration of the at least one additional PF may include at least one of the following: a number of PFs in the at least one additional PF; a number of POs in one additional PF of the at least one additional PF; or a number of UE 104 subgroups in one additional PO in one additional PF.
[0125] In some embodiments, the first PEI is indicative of the configuration of the at least one additional PO or an additional PF including the at least one additional PO. The configuration of the at least one additional PO or the additional PF may include at least one of the following: a number of POs in the at least one additional PO or the additional PF;or a number of UE 104 subgroups in one additional PO.
[0126] For example, a first PEI may trigger at least one additional PO or PF, and indicates the paging configurations of the triggered at least one PO or PF. The triggered PO(s) or PF (s) may be associated with a second PEI, the size of which is determined by the indicated paging configurations. That is to say, the PEI for the dynamically triggered additional PF does not need to have a same size for PEI for the semi-statically configured PEIs, which is beneficial in terms lower PEI signalling overhead, etc. The paging configurations indicated in the PEI may include at least one of following: PO number per PF, UE subgroup number of one PO, or the number of PFs in the at least one PF.
[0127] FIG. 4 illustrates an example of a paging frame structure with dynamic adaptation in accordance with some example embodiments of the present disclosure. As shown in FIG. 4, a PEI for PF#k may trigger an additional PF#0, and provide configurations of the additional PF#0, including e.g., PO number in PF#0, UE subgroup number of PF#0, etc. The size of the PEI for the additional PF#0 is determined by the configurations indicated in the PEI for PF#k. For example, the PEI for the additional PF#0 may include a paging indication field, which has bit (s) . These two parameters, and can be indicated in the PEI for PF#k.
