The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides methods and apparatuses for monitoring paging and acquiring dedicated system information in a wireless communication system.

Various solutions for enhancements on paging early indication-occasion (PEI-O) monitoring are described. An apparatus may receive a first radio resource control (RRC) parameter from a network node. The first RRC parameter indicates an offset before a first paging frame (PF). The apparatus may determine a time location of a PEI-O according to a reference point determined by the offset. The PEI-O is associated with one or more paging occasions (POs) in one or more paging frames (PFs) starting from the first PF. The apparatus may monitor the PEI-O to detect whether a PEI is received from the network node. The PEI indicates whether there is a paging for a subgroup to which the apparatus belongs.

Various solutions for enhancements on paging early indication (PEI) design are described. An apparatus may receive a PEI from a network node of a wireless network. The PEI is included in a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a paging early indication-radio network temporary identifier (PEI-RNTI). The apparatus may monitor a paging occasion (PO) associated with the apparatus in a case that the PEI indicates there being a paging for a subgroup to which the apparatus belongs.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging early indication that indicates one or more paging occasions (POs) in a quantity of paging frames based at least in part on a maximum quantity of paging frames. The UE may process a physical downlink control channel communication received in a PO of the one or more POs. Numerous other aspects are described.

The present disclosure relates to paging methods, paging apparatuses, and storage media. A paging method is applied to a network device and can include determining downlink control information, wherein the downlink control information comprises one or more bits of which a respective bit indicates whether there are one or more paging messages for a terminal group, and sending the downlink control information. A paging method is applied a terminal can include obtaining downlink control information, wherein the downlink control information comprises one or more bits of which a respective bit indicates whether there are one or more paging messages for a terminal group and determining a terminal group to which the terminal belongs, and determining whether to receive paging messages or not based on the terminal group to which the terminal belongs and a bit corresponding to the terminal group.

[Object] To achieve more flexible DRX. [Solution] Provided is a communication control apparatus including: a selection unit configured to select a paging segment from a plurality of paging segments that are repeatedly present during a period having a length of a first discontinuous reception (DRX) cycle for a terminal apparatus; and a control unit configured to perform paging for the terminal apparatus during the selected paging segment if performing the paging. The length of the first DRX cycle is not divisible by a length of each of the plurality of paging segments.

A wireless telecommunications system including first and second terminal devices operable to communicate with one another in a synchronized device-to-device manner. The second terminal device is operable to selectively achieve synchronization for receiving data transmissions from the first terminal device using direct synchronization signalling transmitted by the first terminal device or indirect synchronization signalling transmitted by another network entity, such as a base station. The second terminal device is configured to preferentially seek indirect synchronization over direct synchronization, unless the second terminal device detects synchronization signalling transmitted by the first terminal device is associated with a predefined characteristic that indicates the synchronization signalling transmitted by the first terminal device is high priority synchronization signalling, in which case the second terminal device is configured to preferentially seek synchronization using the high priority direct synchronization signalling from the first terminal device over indirect synchronization signalling transmitted by the other network entity.

A method of operating an infrastructure node in a wireless communications system is provided. The method comprises detecting that downlink messages for a communications device to decode should be transmitted by the node in one or more of a plurality or temporally spaced paging occasions, and determining that a wake-up signal (WUS) should be transmitted by the node to the communications device in advance of each of the one or more paging occasions which comprise the downlink messages for the communications device to decode, determining that a time since a most recent transmission of a signal which can be used by the communications device to re-synchronise with the node is greater than a predetermined threshold and transmitting, in response to determining that the time since the most recent transmission from the infrastructure equipment to the communications device is greater than the predetermined threshold, a preamble signal to the communications device.

An apparatus and method are provided for transmitting/receiving a paging message in a next generation communication system.

A page reception method for the multi-subscriber identity module (SIM) mobile communication device includes: determining whether one or more upcoming system information block (SIB) system frame numbers (SFNs) will overlap with a PICH occasion on a paging indicator channel (PICH) for a subscription; in response to determining that the one or more upcoming SIB SFNs will overlap with the PICH occasion, identifying a repetition period of the one or more upcoming SIB SFNs; determining whether the repetition period of the one or more upcoming SIB SFNs is not less than a discontinuous reception receive (DRx) cycle for the PICH occasion; and in response to determining that the repetition period of the one or more upcoming SIB SFNs is not less than the discontinuous reception cycle for the PICH occasion, preventing decoding of the one or more upcoming SIB SFNs that overlap with the PICH occasion.
