Description

Cross-reference to related applications

[0001] This application claims priority to U.S. Provisional Application No. 63 / 494320, filed April 5, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The example embodiments generally relate to techniques for implementing system information acquisition in extended connectionless reception, and more specifically to techniques for applying system information acquisition processes. Background Technology

[0003] Various types of user equipment (UEs) can be configured with extended discontinuous reception to conserve battery power. When operating in an extended discontinuous reception idle or inactive mode, the UE enters a phase where it does not actively listen for downlink transmissions (such as paging). The UE monitors paging timing cyclically according to the (e)DRX used. This is technically advantageous because battery life can be preserved for a longer period compared to being in a continuously active state. However, not all cells allow or support extended discontinuous reception. UEs are often mobile and can move between different cells when operating in an idle or inactive state. This can cause technical problems when the UE enters a cell that does not allow extended discontinuous reception. Furthermore, the cell in which the UE is currently located may switch from one that allows extended discontinuous reception to one that does not. The same technical problems arise in this case, causing the UE and the base station to operate based on different system information.

[0004] The base station can modify system information and will transmit the modified system information on the cell. The base station can indicate the system information change to the UE using `systemInfoModification` or `systemInfoModification-eDRX` in a short message. The UE will apply an information collection procedure to receive the modified system information during the modification period or extended discontinuous reception collection period. Sometimes, the base station may expect the UE to apply the system information collection procedure at the beginning of the next modification period or at the beginning of the next eDRX collection period boundary. The UE can be configured by the core network with extended discontinuous reception, which has an extended discontinuous reception cycle longer or shorter than the modification period. The UE can move to a non-broadcasting location. eDRX-AllowedIdle The new cell indicates that the user equipment is not allowed to operate in the eDRX configured in the core network. The network can also change system information; the base station sends a short message with the systemInfoModification bit set to the user equipment. It has been specified that if H-SFN is provided in SIB1 and the UE is configured with eDRX, the modification period boundary is determined by the H-SFN. The definition of an SFN value modulo m=0 (1024+SFN). This may lead to the selection of an incorrect modification cycle boundary when a UE is configured with eDRX but is not operating within it. A UE may be configured with eDRX for RAN paging in inactive and / or CN paging in IDLE, but the UE may not necessarily operate within it, for example, when eDRX is not allowed for a specific RRC state, where the UE is on a cell that the UE has already (re)selected. Summary of the Invention

[0005] A method, apparatus, and computer program product for determining when to apply system information collection cycles are disclosed. By determining when to apply system information collection cycles, user equipment and base stations can apply the same system information.

[0006] In an example embodiment, a method is provided, comprising: an extended discontinuous reception configuration. The method further comprises: receiving a modified period configuration. The method further comprises: receiving a message indicating modified system information. The method further comprises: determining an operational state for extended discontinuous reception. The method further comprises: based on the message and the operational state, applying a system information acquisition process at the beginning of the next modification period based on the modified period configuration, or at the beginning of the next extended discontinuous reception acquisition period based on the extended discontinuous reception configuration.

[0007] In the example embodiment, if the operation status does not indicate operation in extended discontinuous reception and the message includes the set systemInfoModification bit, the system information acquisition process is applied at the beginning of the next modification cycle.

[0013] In the example implementation, “Allowed enhanced inactive eDRX cycles” includes the indication “Allowed inactive eDRX cycles > 10.24s”.

[0014] In the example embodiment, if "Allowed inactive eDRX>10.24s" does not exist in the system information, the UE can stop using "Inactive eDRX>10.24s" for radio access network (RAN) paging in RRC_INACTIVE. In the example embodiment, when "Inactive eDRX>10.24s" for RAN paging in RRC_INACTIVE and "Allowed inactive eDRX>10.24s" does not exist in the system message, the UE can stop operating in eDRX.

[0101] Figure 2An example device 200 is depicted that can be configured to function as a user equipment 120 or a base station 140. For example... Figure 2 As shown, the device includes a processing circuitry system 220, a memory 240, and a communication interface 260, and is associated with, or in communication with, the processing circuitry system 220, the memory 240, and the communication interface 260. The processing circuitry system 220 may communicate with the memory 240 via a bus to transfer information between device components. The memory device may be non-transitory and may include, for example, one or more volatile and / or non-volatile memories. In other words, for example, the memory device may be an electronic storage device (e.g., a computer-readable storage medium) that includes gates configured to store data (e.g., bits) accessible by a machine (e.g., a computer device similar to the processing circuitry system). The memory device may be configured to store information, data, content, applications, instructions, etc., to enable the device to perform various functions according to exemplary embodiments of this disclosure. For example, the memory device may be configured to buffer input data for processing by the processing circuitry system. Additionally or alternatively, the memory device may be configured to store instructions for execution by the processing circuitry system.

[0102] In some embodiments, device 200 may be embodied in the various computing devices described above. However, in some embodiments, the device may be embodied as a chip or a chip assembly. In other words, the device may include one or more physical packages (e.g., chips) that include materials, components, and / or wires on a structural assembly (e.g., a substrate). The structural assembly may provide physical strength, size savings, and / or electrical interaction constraints for the component circuitry system included on it.

For example, the processing circuitry system can be embodied as one or more hardware processing units of various types, such as coprocessors, microprocessors, controllers, digital signal processors (DSPs), processing elements with or without an accompanying DSP, or various other circuitry systems including integrated circuits, such as ASICs (Application-Specific Integrated Circuits), FPGAs (Field-Programmable Gate Arrays), microcontroller units (MCUs), hardware accelerators, application-specific computer chips, etc. Therefore, in some embodiments, the processing circuitry system may include one or more processing cores configured to execute independently. A multi-core processing circuitry system enables multiple processing within a single physical package. Additionally, or alternatively, the processing circuitry system may include one or more processors configured to be cascaded via a bus to enable independent execution of instructions, pipelines, and / or multiple threads.

[0104] In an example embodiment, processing circuitry 220 may be configured to execute instructions stored in memory device 240 or otherwise accessible to the processing circuitry. Alternatively or additionally, the processing circuitry may be configured to perform hard-coded functions. Thus, whether configured by hardware or software methods, or by a combination thereof, the processing circuitry can represent an entity (e.g., physically embodied in a circuitry) capable of performing operations according to embodiments of this disclosure while correspondingly configured. Thus, for example, when the processing circuitry is embodied as an ASIC, FPGA, etc., the processing circuitry may be specifically configured as hardware for performing the operations described herein. Alternatively, as another example, when the processing circuitry is embodied as an executor of instructions, the instructions may specifically configure the processor to perform the algorithms and / or operations described herein when the instructions are executed. However, in some cases, the processing circuitry may be a processor of a specific device (e.g., an image or video processing system) configured to further configure the processing circuitry to employ embodiments via instructions for performing the algorithms and / or operations described herein. The processing circuitry may include, but is not limited to, the following configurations to support the operation of the processing circuitry: clock, arithmetic logic unit (ALU), and logic gates.

[0105] Communication interface 260 can be any component, such as a device or circuitry system embodied in hardware or a combination of hardware and software, configured to receive and / or transmit data including media content in the form of video or image files, one or more audio tracks, etc. In this regard, the communication interface may include, for example, an antenna (or multiple antennas) and hardware and / or software supporting communication with a wireless communication network. Additionally or alternatively, the communication interface may include circuitry for interacting with the antenna(s) to enable the transmission of signals via the antenna(s) or the reception of signals received via the antenna(s). In some environments, the communication interface may alternatively or also support wired communication. Thus, for example, the communication interface may include a communication modem and / or other hardware / software for supporting communication via cable, Digital Subscriber Line (DSL), Universal Serial Bus (USB), or other mechanisms.
