[0049] Aspects of the present disclosure are described in the context of a wireless communications system. FIG. 1 illustrates an example of a wireless communications system 100 that supports configurations for LP-WUS related procedures 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 some other implementations, the wireless communications system 100 may be a 6G 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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. 1. 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. 1. 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.
[0054] 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.
[0055] 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, N3, 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) .
[0056] 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.
[0057] 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) ) .
[0058] 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.
[0059] 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) .
[0060] 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.
[0061] 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 registration management, mobility management, connection management, access authentication / authorization, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0062] 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, N3, 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) .
[0063] 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.
[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] When LP-WUS is received by the LR of a UE, the LR will trigger the MR of the UE to wake up to monitor Paging in RRC_IDLE / INACTIVE state. The gNB configures, in system information, entry and exit conditions to monitor LP-WUS. The UE may start monitoring LP-WUS when measurements using the MR are above the configured entry threshold (s) , and the measurements using the LR are above the entry threshold (s) , if configured. The UE monitors paging early indication (PEI) or monitors paging directly when the measurement using LR are below the configured exit thresholds.
[0070] Power saving in RRC_IDLE and RRC_INACTIVE can also be achieved by allowing UEs configured with LP-WUS to relax serving cell measurements on MR and / or offload serving cell measurements from MR to the LR. For RRM measurement relaxation case, serving cell measurement and neighboring cell measurement are relaxed on MR while LR also performs the serving cell measurement. For serving cell measurement offloading case, serving cell measurement is fully offloaded from MR to LR while MR performs no measurement on serving cell. Entry condition for serving cell measurement relaxation is fulfilled when measurements using MR and optionally using LR are above the configured entry threshold (s) . Entry conditions for serving cell measurement offloading is fulfilled at least when the MR measurement is greater than a certain RSRP threshold, and LR measurement could also be considered. The UE stops serving cell measurement offloading when LR measurement are below the configured exit threshold (s) , FFS on the exit conditions of serving ell measurement relaxation.
[0071] Table 1 illustrates some entry / exit conditions configured in System Information Block (SIB) for UEs in RRC_IDLE / INACTIVE state configured with LP-WUS. Table 1
[0072] It has been proposed to merge the entry / exit condition for serving cell RRM measurement offloading or serving cell RRM measurement relaxation or neighboring cell RRM measurement relaxation and LP-WUS monitoring to reduce the number of total thresholds for LP-WUS as possible, which can be further divided as Direction a) (i.e., merging LP-WUS monitoring and serving cell offloading) and Direction b) (i.e., merging LP-WUS monitoring and Rel-19 RRM relaxation) .
[0073] Furthermore, it has been proposed that it is up to the network (NW) to configure either serving cell relaxation or serving cell offloading or both in one cell. In addition, is has not been determined or specified on whether entry / exit condition for LP-WUS monitoring is always configured in SIB. Then, further enhancements are needed in various aspects, for example, how does the network provide those entry / exit conditions in SIB; and if one of the relaxation or offloading entry / exit conditions is agreed to be merged with LP-WUS monitoring but it has not been configured by NW, how does the UE determine to start / stop LP-WUS monitoring.
[0074] In view of the above, some embodiments of the present disclosure provide solutions regarding configurations of conditions for LP-WUS related procedures. With some embodiments of the present disclosure, the network configuration details in SIB and corresponding UE behaviors when entry / exit conditions are fulfilled are designed by taking potential merging directions into consideration, thus reducing resource overhead for configuring conditions for LP-WUS related procedures.
[0075] Reference is now made to FIG. 2, which illustrates an example signaling chart of a communication process that supports configurations for LP-WUS related procedures 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. 1. The process 200 may involve the UE 104 and the network entity 102. The network entity 102 may be implemented as a base station. The UE 104 may be implemented as a UE supporting SSB transmission. 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. It is also to be understood that terms used herein are terminologies in 5G NR systems, and may be interchangeably used with other terminologies (but with same or similar functions) that might be used in future wireless communication system such as 6G.
[0076] In the process 200, the base station 102 transmits (201) a configuration 202 to the UE 104. The configuration 202 includes at least one condition for at least one low-power wakeup signal (LP-WUS) related procedure. The UE 104 receives (203) the configuration 202 from the base station 102 and determines (204) whether to perform the at least one LP-WUS related procedure based on the at least one condition.
[0077] In some embodiments, if an entry condition among the at least one condition is applied for one or more LP-WUS related procedures among the at least one LP-WUS related procedure, the UE 104 may start performing the one or more LP-WUS related procedures when the entry condition is satisfied. If an exit condition among the at least one condition is applied for one or more LP-WUS related procedures among the at least one LP-WUS related procedure, the UE 104 may stop performing the one or more LP-WUS related procedures when the exit condition is satisfied.
[0078] In some embodiments, the at least one LP-WUS related procedure may include at least one of the following: LP-WUS monitoring, serving cell measurement offloading or radio resource management (RRM) measurement relaxation. For example, respective entry / exit conditions applied for at least one of LP-WUS monitoring, serving cell measurement offloading or RRM measurement relaxation may be configured by the network in SIB.
[0079] In some embodiments, the LP-WUS monitoring is enabled. That is, the at least one condition may include entry / exit conditions applied for the LP-WUS monitoring, and the UE 104 may determine whether to start performing or stop performing the LP-WUS monitoring based on the entry / exit conditions applied for the LP-WUS monitoring. As used herein, the expression “a LP-WUS related procedure is enabled” means that the LP-WUS related procedure is supported in the cell. In some embodiments, the configuration 202 may further include a first indication indicating whether the serving cell measurement offloading is enabled or not. Alternatively or additionally, the configuration 202 may further include a second indication indicating whether the RRM measurement relaxation is enabled or not. In an example implementation, the configuration 202 may include two 1-bit indications, indicating whether serving cell measurement offloading and R19 RRM measurement relaxation is enabled / supported or not in the cell, respectively. In another example implementation, the configuration 202 may include one 1-bit indication, indicating whether serving cell measurement offloading is enabled / supported or not in the cell; while dedicated entry / exit conditions for R19 RRM measurement relaxation are configured, implicitly indicating that the R19 RRM measurement relaxation is enabled / supported in the cell. In a further example implementation, the configuration 202 may include one 1-bit indication, indicating whether R19 RRM measurement relaxation is enabled / supported or not in the cell; while dedicated entry / exit conditions for serving cell measurement offloading are configured, implicitly indicating that the serving cell measurement offloading is enabled / supported in the cell. The LP-WUS monitoring is considered as enabled / supported by default in the cell as long as the configuration 202 is provided.
[0080] If the serving cell measurement offloading is enabled, the at least one condition may include entry / exit conditions applied for the serving cell measurement offloading, and the UE 104 may determine whether to start performing or stop performing the serving cell measurement offloading based on the entry / exit conditions applied for the serving cell measurement offloading. Similarly, if the RRM measurement relaxation is enabled, the at least one condition may include entry / exit conditions applied for the RRM measurement relaxation, and the UE 104 may determine whether to start performing or stop performing the RRM measurement relaxation based on the entry / exit conditions applied for the RRM measurement relaxation.
[0081] In some embodiments, the at least one condition includes at least one common condition. For example, common entry / exit conditions on MR / LR thresholds may be configured in SIB. For example, a common entry condition may be defined as servicing cell measurement on both MR and LR (if configured) are above the configured thresholds; a common exit condition may be defined as serving cell measurement on LR is below a configured threshold. The terms “common condition” and “default condition” may be used interchangeably. The UE 102 should further determine which LP-WUS related procedure (s) the common condition (s) can be applied for.
[0082] In some implementations, the at least one condition includes at least one common condition, and the configuration 202 may further include bit information indicating whether the at least one common condition is applied for the at least one LP-WUS related procedure. That is, the configuration 202 may include an explicit indication (e.g., a bitmap) indicating applicability of the common condition (s) for LP-WUS related procedure (s) . If the at least one common condition is applied for a first LP-WUS related procedure among the at least one LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one common condition. If the at least one condition includes at least one dedicated condition for the first LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one dedicated condition.
[0083] FIG. 3 illustrates a first example of configurations of conditions for LP-WUS related procedures in accordance with some example embodiments of the present disclosure. As shown in FIG. 3, a bitmap may be used to indicate whether the common condition (s) can be applied for LP-WUS monitoring / serving cell measurement offloading / RRM measurement relaxation or not. In the example shown in FIG. 3, a bitmap of “1 / 1 / 0” indicates that the common condition (s) can be applied for LP-WUS monitoring and serving cell measurement offloading, enabling configuration for Direction a) , i.e., merging LP-WUS monitoring and serving cell measurement offloading. The UE may determine to start performing LP-WUS monitoring and serving cell measurement offloading if an entry condition in the common condition (s) is satisfied, and stop performing LP-WUS monitoring and serving cell measurement offloading if an exit condition in the common condition (s) is satisfied. If there is no dedicated condition configured for RRM measurement relaxation, which implies that the network does not support RRM measurement relaxation in the cell, the UE would not perform RRM measurement relaxation. If a dedicated entry condition and a dedicated exit condition for RRM measurement relaxation are configured in SIB, the UE may determine to start performing RRM measurement relaxation if the dedicated entry condition is satisfied, and stop performing RRM measurement relaxation if the dedicated exit condition is satisfied.
[0084] Turning back to FIG. 2, in some implementations, the at least one condition includes at least one common condition. If a first LP-WUS related procedure among the at least one LP-WUS related procedure is enabled and the at least one condition includes no dedicated condition for the first LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one common condition. If the at least one condition includes at least one dedicated condition for the first LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one dedicated condition. In other words, the UE 102 may determine whether the common condition (s) can be applied for an enabled LP-WUS related procedure based on an implicit indication (i.e., whether dedicated entry / exit conditions for the enabled LP-WUS related procedure is configured) . Two 1-bit indications may be used to indicate the support of serving cell measurement offloading, and R19 RRM measurement relaxation respectively. If dedicated entry / exit conditions are configured for an enabled LP-WUS related procedure, the UE may follow the dedicated entry / exit conditions; if no dedicate entry / exit conditions are configured for an enabled LP-WUS related procedure, the UE may follow common entry / exit conditions to start / stop the enabled LP-WUS related procedure.
[0085] FIG. 4 illustrates a second example of configurations of conditions for LP-WUS related procedures in accordance with some example embodiments of the present disclosure. Three implementations are shown in the example of FIG. 4.
[0086] In the first implementation, the network configurations include common entry / exit conditions and dedicated entry / exit conditions for RRM measurement relaxation (if RRM measurement relaxation is enabled) . The common entry / exit conditions may be applied for LP-WUS monitoring (if enabled in the cell) and serving cell measurement offloading (if enabled in the cell) , enabling configuration for Direction a) , i.e., merging LP-WUS monitoring and serving cell measurement offloading. If entry / exit conditions for R19 RRM measurement relaxation are explicitly configured, it implies that the common entry / exit conditions are used for LP-WUS monitoring and serving cell measurement offloading if it is supported. UE determines to start / stop the LP-WUS monitoring and serving cell measurement offloading when the configured common entry / exit conditions are satisfied. UE determines to start / stop R19 RRM measurement relaxation when the additional configured R19 RRM measurement relaxation entry / exit conditions are satisfied. If no additional R19 RRM measurement relaxation entry / exit conditions are configured, it means that the network does not support the R19 RRM measurement relaxation in this cell.
[0087] In the second implementation, the network configurations include common entry / exit conditions and dedicated entry / exit conditions for serving cell measurement offloading (if serving cell measurement offloading is enabled) . The common entry / exit conditions may be applied for LP-WUS monitoring (if enabled in the cell) and RRM measurement relaxation (if enabled in the cell) , enabling configuration for Direction b) , i.e., merging LP-WUS monitoring and RRM measurement relaxation. If entry / exit conditions for serving cell measurement offloading are explicitly configured, it implies that the common entry / exit conditions are used for LP-WUS monitoring and R19 RRM measurement relaxation if it is supported. UE determines to start / stop the LP-WUS monitoring and R19 RRM measurement relaxation when the configured common entry / exit conditions are satisfied. UE determines to start / stop serving cell measurement offloading when the additional configured serving cell measurement offloading entry / exit conditions are satisfied. If no additional serving cell measurement offloading entry / exit conditions are configured, it means that the network does not support the serving cell measurement offloading in this cell.
[0088] In the third implementation, the network configurations include common entry / exit conditions and dedicated entry / exit conditions for LP-WUS monitoring (if LP-WUS monitoring is enabled) . The common entry / exit conditions may be applied for serving cell measurement offloading (if enabled in the cell) or RRM measurement relaxation (if enabled in the cell) . If entry / exit conditions for LP-WUS monitoring entry / exit are explicitly configured, it implies that the common entry / exit conditions are used for serving cell measurement offloading or R19 RRM measurement relaxation if it is supported. UE determines to start / stop the serving cell measurement offloading or R19 RRM measurement relaxation (based on which one if enabled / supported) when the configured common entry / exit conditions are satisfied. UE determines to start / stop serving LP-WUS monitoring when the additional configured LP-WUS monitoring entry / exit conditions are satisfied.
[0089] Turning back to FIG. 2, in some embodiments, the at least one condition includes at least one first condition for the LP-WUS monitoring. The UE 104 may determine whether to perform the LP-WUS monitoring based on the at least one first condition. The configuration 202 may further include a bit indication indicating whether the at least one first condition is applied for each of the serving cell measurement offloading or the RRM measurement relaxation. If the at least one first condition is applied for a first LP-WUS related procedure among the serving cell measurement offloading and the RRM measurement relaxation, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one first condition. If the at least one condition includes at least one dedicated condition for the first LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one dedicated condition.
[0090] In some implementations, the bit indication may be implemented using one bit. A first bit value of the bit indication indicates that the at least one first condition is applied for the LP-WUS monitoring and the serving cell measurement offloading. A second bit value of the bit indication indicates that the at least one first condition is applied for the LP-WUS monitoring and the RRM measurement relaxation. Absence of the bit indication indicates that the at least one first condition is applied for the LP-WUS monitoring.
[0091] In other words, LP-WUS monitoring entry / exit condition is always configured in SIB, e.g., a LP-WUS monitoring entry condition may be defined as servicing cell measurement on both MR and LR (if configured) are above the configured thresholds; a LP-WUS monitoring exit condition may be defined as serving cell measurement on LR is below a configured threshold.
[0092] An additional 1-bit indication (i.e., with values 0 and1) is used to indicate whether the LP-WUS monitoring condition is also used for serving cell measurement offloading or R19 RRM measurement relaxation. FIG. 5 illustrates a third example of configurations of conditions for LP-WUS related procedures in accordance with some example embodiments of the present disclosure.
[0093] For example, as shown in FIG. 5, in the case that the additional 1-bit indication is set to 0, the LP-WUS monitoring is merged with serving cell measurement offloading. If R19 RRM measurement relaxation is also supported in the cell, the network may further configure the entry / exit condition for R19 RRM measurement relaxation explicitly. In the case that the additional 1-bit indication is set to 1, the LP-WUS monitoring is merged with R19 RRM measurement relaxation. If serving cell measurement offloading is also supported in the cell, the network may further configure the entry / exit condition for serving cell measurement offloading explicitly. In the case that the additional 1-bit indication is absent, it implies that LP-WUS monitoring entry / exit conditions is merged with neither serving cell measurement offloading or R19 RRM measurement relaxation.
[0094] In the case that serving cell measurement offloading is supported in the cell, and the additional 1-bit indication indicates that the LP-WUS monitoring entry / exit conditions are used for LP-WUS monitoring and serving cell measurement offloading, UE determines to start / stop LP-WUS monitoring and serving cell measurement offloading when the configured entry / exit condition for LP-WUS monitoring is satisfied. If dedicated entry / exit conditions for R19 RRM measurement relaxation are configured, UE determines to start / stop R19 RRM measurement relaxation when the dedicated entry / exit conditions for R19 RRM measurement relaxation are satisfied. As used herein, the term “dedicated (entry / exit) conditions” can be used interchangeably with “separate (entry / exit) conditions” and refer to (entry / exit) conditions dedicatedly configured for a LP-WUS related procedure.
[0095] In the case that R19 RRM measurement relaxation is supported in the cell, and the additional 1-bit indication indicates that the LP-WUS monitoring entry / exit conditions are used for R19 RRM measurement relaxation, UE determines to start / stop LP-WUS monitoring and R19 RRM measurement relaxation when the configured entry / exit condition for LP-WUS monitoring is satisfied. If dedicated entry / exit conditions for serving cell measurement offloading are configured, UE determines to start / stop serving cell measurement offloading when the dedicated entry / exit conditions for serving cell measurement offloading are satisfied.
[0096] In some implementations, two 1-bit indications may be used to indicate the support of serving cell measurement offloading, and R19 RRM measurement relaxation respectively, and the additional 1-bit indication may be used to indicate whether the LP-WUS monitoring entry / exit conditions can be applied to serving cell measurement offloading or R19 RRM measurement relaxation.
[0097] In some alternative implementations, based on the additional 1-bit indication, the UE may determine whether serving cell measurement offloading or R19 RRM measurement relaxation is supported or not and determine whether the LP-WUS monitoring entry / exit conditions can be applied to serving cell measurement offloading or R19 RRM measurement relaxation. For example, if the additional 1-bit indication indicates that LP-WUS monitoring is merged with serving cell measurement offloading (e.g., the additional 1-bit indication is set to 0) , then serving cell measurement offloading is considered as enabled / supported by default, while whether RRM measurement relaxation is supported or not depends on whether dedication entry / exit conditions for RRM measurement relaxation are configured or not; if no dedication entry / exit conditions for RRM measurement relaxation are configured, then it can be considered as the R19 RRM measurement relaxation is not supported / enabled in the cell. In this way, no explicit indication of the support of serving cell measurement offloading, and R19 RRM measurement relaxation is needed.
[0098] In some embodiments, the at least one condition includes at least one first condition for the LP-WUS monitoring. The UE 104 may determine whether to perform the LP-WUS monitoring based on the at least one first condition. If a first LP-WUS related procedure among the serving cell measurement offloading and the RRM measurement relaxation is enabled and the at least one condition includes no dedicated condition for the first LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one first condition. If the at least one condition includes at least one dedicated condition for the first LP-WUS related procedure, the UE 104 may determine whether to perform the first LP-WUS related procedure based on the at least one dedicated condition. In some implementations, two 1-bit indications may be used to indicate the support of serving cell measurement offloading, and R19 RRM measurement relaxation respectively. If R19 RRM measurement relaxation conditions are dedicatedly configured, it implies that the LP-WUS monitoring entry / exit condition are used for LP-WUS monitoring and serving cell measurement offloading if it is supported, thus enabling configuration for Direction a) . If serving cell measurement offloading conditions are dedicatedly configured, it implies that the LP-WUS monitoring entry / exit condition are used for LP-WUS monitoring and R19 RRM measurement relaxation if it is supported, thus enabling configuration for Direction b) .
[0099] For Direction a) , in the case that serving cell measurement offloading is supported in the cell, UE determines to start / stop LP-WUS monitoring and serving cell measurement offloading when the configured entry / exit condition for LP-WUS monitoring is satisfied. If R19 RRM measurement relaxation is supported and dedicated entry / exit conditions for R19 RRM measurement relaxation are configured, UE determines to start / stop R19 RRM measurement relaxation when the dedicated entry / exit conditions for R19 RRM measurement relaxation are satisfied. For Direction b) , in the case that serving cell measurement relaxation is enabled in the cell, UE determines to start / stop LP-WUS monitoring and serving cell measurement relaxation when the configured entry / exit condition for LP-WUS monitoring is satisfied. If serving cell measurement offloading is supported and dedicated entry / exit conditions for serving cell measurement offloading are configured, UE determines to start / stop serving cell measurement offloading when the dedicated entry / exit conditions for serving cell measurement offloading are satisfied.
[0100] In some embodiments, the at least one condition includes at least one first condition. If a first LP-WUS related procedure among the serving cell measurement offloading and the RRM measurement relaxation is not enabled, the UE 104 may determine whether to perform the LP-WUS monitoring based on the at least one first condition. If the first LP-WUS related procedure is enabled, the UE 104 may determine whether to perform the LP-WUS monitoring and the first LP-WUS related procedure based on the at least one first condition. If the at least one condition may further include at least one second condition, the UE 104 may determine whether to perform a second LP-WUS related procedure among the serving cell measurement offloading and the RRM measurement relaxation based on the at least one second condition. If the at least one condition only includes the at least one first condition, and does not include the at least one second condition, it means that the second LP-WUS related procedure is not supported in the cell.
[0101] In some implementations, the first LP-WUS related procedure may be predefined as the serving cell measurement offloading. Then, the second LP-WUS related procedure is the RRM measurement relaxation. In other words, the combined entry / exit conditions of LP-WUS monitoring and serving cell measurement offloading are configured in SIB by default. That is, LP-WUS monitoring and serving cell measurement offloading are merged by default, i.e., Direction a) by default. If serving cell measurement offloading is supported in the cell, combined entry / exit conditions are configured for LP-WUS monitoring and serving cell measurement offloading. If R19 RRM measurement relaxation is supported in the cell, dedicated entry / exit conditions are configured for R19 RRM measurement relaxation. In some example implementations, two 1-bit indications may be used to indicate the support of serving cell measurement offloading, and R19 RRM measurement relaxation respectively. In some alternative example implementations, one 1-bit indication may be used to indicate whether serving cell measurement offloading is enabled / supported or not in the cell; while whether the R19 RRM measurement relaxation is enabled / supported or not in the cell may be implicitly indicated based on whether dedicated entry / exit conditions for R19 RRM measurement relaxation are configured. If two sets of entry / exit conditions are provided in SIB, entry / exit condition #1 is for LP-WUS monitoring and serving cell measurement offloading, and entry / exit condition #2 is for R19 RRM measurement relaxation. UE may determine to start / stop of LP-WUS monitoring and serving cell measurement offloading (if serving cell measurement offloading is supported in the cell) when entry / exit condition #1 is satisfied. If serving cell measurement offloading is not supported in the cell, UE determines to start / stop of LP-WUS monitoring only when entry / exit condition #1 is satisfied. If the entry / exit condition #2 is configured, UE may determine to start / stop R19 RRM measurement relaxation when entry / exit condition #2 is satisfied. If the entry / exit condition #2 is not configured, it may be considered as that the R19 RRM measurement relaxation is not supported in the cell.
[0102] Alternatively, the first LP-WUS related procedure may be predefined as the RRM measurement relaxation. Then, the second LP-WUS related procedure is the serving cell measurement offloading. In other words, the combined entry / exit conditions of LP-WUS monitoring and the RRM measurement relaxation are configured in SIB by default. That is, LP-WUS monitoring and the RRM measurement relaxation are merged by default, i.e., Direction b) by default. If the RRM measurement relaxation is supported in the cell, combined entry / exit conditions are configured for LP-WUS monitoring and the RRM measurement relaxation. If serving cell measurement offloading is supported in the cell, dedicated entry / exit conditions are configured for serving cell measurement offloading. In some example implementations, two 1-bit indications may be used to indicate the support of serving cell measurement offloading, and R19 RRM measurement relaxation respectively. In some alternative example implementations, one 1-bit indication may be used to indicate whether R19 RRM measurement relaxation is enabled / supported or not in the cell; while whether the serving cell measurement offloading is enabled / supported or not in the cell may be implicitly indicated based on whether dedicated entry / exit conditions for serving cell measurement offloading are configured. If two sets of entry / exit conditions are provided in SIB, entry / exit condition #1 is for LP-WUS monitoring and R19 RRM measurement relaxation, and entry / exit condition #2 is for serving cell measurement offloading. UE may determine to start / stop of LP-WUS monitoring and R19 RRM measurement relaxation (if R19 RRM measurement relaxation is supported in the cell) when entry / exit condition #1 is satisfied. If R19 RRM measurement relaxation is not supported in the cell, UE determines to start / stop of LP-WUS monitoring only when entry / exit condition #1 is satisfied. If the entry / exit condition #2 is configured, UE may determine to start / stop serving cell measurement offloading when entry / exit condition #2 is satisfied.
