A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.

A communication system is disclosed in which a base station receives, from a core network entity, a paging request for paging an MTC device. The base station determines a paging occasion for sending to said MTC device paging related information, wherein the paging occasion is defined such that it identifies a plurality of subframes in which the paging related information can be sent and repeated. The base station sends (and repeats, as appropriate) the paging related information in the plurality of subframes identified by the paging occasion.

According to certain embodiments, a method performed by a wireless device for paging occasion (PO) allocation is provided. The method includes determining that a PO configured for the wireless device in a Discontinuous Reception (DRX) cycle is problematic. A non-problematic PO is selected based on one or more criteria. One or more paging messages are monitored for during the selected non-problematic PO.

Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

Embodiments of this application disclose a communication method and a related apparatus, so that remote UE can communicate with a network via relay UE that resumes or establishes a radio resource control RRC connection, to ensure communication quality of the remote UE. The method includes: A first access network device receives a first message sent by first UE, where the first message includes a first identifier of second UE, and the first identifier is an identifier of the second UE in an RRC inactive state or an RRC idle state. The first access network device pages the second UE based on the first message. The first access network device sends a second message to the first UE, where the second message indicates the first UE to perform path switching, the second message includes a second identifier of the second UE.

A communication method applied to a terminal device includes receiving a first message from a network device. The first message includes configuration information of at least one first reference signal. The communication method also includes receiving a second message from the network device. The second message indicates an availability of at least one second reference signal, the at least one second reference signal has a quasi co-location (QCL) relationship with at least one synchronization signal/physical broadcast channel block (SSB), and the at least one first reference signal includes the at least one second reference signal. The communication method further includes receiving, from the network device and based on the configuration information and the second message, an available reference signal of the at least one second reference signal.

The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for paging. The UE first monitors a first signaling in X time intervals respectively, and then receives a first radio signal. The first signaling is used for determining scheduling information for the first radio signal. The scheduling information includes at least one of {occupied time-frequency resource, adopted MCS, subcarrier spacing of subcarriers in occupied frequency domain resource}. The first radio signal carries a paging message. The frequency domain resource is used for transmitting the first signaling belongs to a first subband. The first subband includes a positive integer number of consecutive subcarriers in frequency domain. At least one of {location of the first subband in frequency domain, subcarrier spacing of subcarriers included in the first subband} is used for determining the X time intervals.

Techniques are provided for positioning of user equipment (UE) with paging messages. An example method for positioning a user equipment with paging messages includes receiving a positioning paging message with a user equipment in an idle state, measuring positioning measurements in response to receiving the positioning paging message, determining location information based at least in part on the positioning measurements, and transmitting the location information via a random access procedure.
