The present invention relates to a user device, a base station, and data transmission and reception methods to be performed by a user device and a base station in a communications system. The user device comprises circuitry which, in operation, calculates the starting location of a paging region comprising resources in which user devices are paged, the paging region including paging information for paging said user device; and determines an offset with respect to the starting location of the paging region, the offset indicating the location of the paging information for paging said user device relative to the starting location of the paging region.

A location area management method and a device, the location area management method including receiving, by a single radio controller, a first request message, where the first request message is used by user equipment UE to request a location update, generating, by the single radio controller, a paging area list of the UE according to the first request message, where the paging area list includes a location area identity of a location area of at least one network standard, adding, by the single radio controller, the paging area list of the UE to a first response message, and sending the first response message to the UE.

Extended sleep in a wireless device. In an embodiment, synchronized parameters, used by a wireless device to define an extended-sleep cycle, are stored at a system. Based on the synchronized parameters, the system determines a transmission time at which to transmit a message over the wireless communication network such that the message will be received by the wireless device during a portion of the extended-sleep cycle during which the wireless device is monitoring paging occasions. The message is then queued until it is transmitted at the transmission time.

Certain aspects of the present disclosure relate to a methods and apparatus for wireless communication. In one aspect, a method of wireless communication comprises assigning, by an access point, an interval of time for transmission on an unlicensed communication spectrum to a LTE-U device, and broadcasting an anchor signal during the interval of time on the unlicensed communication spectrum, the anchor signal comprising a paging indication for the LTE-U device. In another aspect, a method of wireless communication comprises determining, by a LTE-U device, an interval of time for reception of a paging indication on an unlicensed communication spectrum and receiving an anchor signal during the interval of time on the unlicensed communication spectrum, the anchor signal comprising the paging indication.

This application provides an information transmission method and an apparatus and relates to the field of communications technologies, to resolve a problem of power waste caused when a communications device blindly monitors downlink control information in all monitoring occasions. The method includes: determining, by a communications device, information about a target beam; determining a target monitoring occasion based on the information about the target beam and a mapping relationship between information about a beam and a monitoring occasion, where the target monitoring occasion is in a system information window, and the system information window is used for OSI; and monitoring downlink control information in the target monitoring occasion.

A core network node of a first public land mobile network (PLMN) receives, from a wireless device, a requested international mobile subscriber identity (IMSI) offset value for offsetting an IMSI of the wireless device. The core network node transmits, to the wireless device, an accepted IMSI offset value for offsetting the IMSI of the wireless device. First paging occasions of the first PLMN are derived using an alternative IMSI. The alternative IMSI is determined based on a sum of the IMSI of the wireless device and the accepted IMSI offset value.

A programmable signal generator and radio controller for providing dispatch paging tone out frequencies to first responders and other selected areas. The signal generator is capable of performing tone-outs to various first responders and being cross compatible with prior and future evolutionary systems. The signal generator uses plain-text console interface and plain-text tone-out parameter definitions allowing programming without special software, apps, or Internet connectivity. The signal generator is capable of controlling operational functions of connected radio transceiver equipment including initiating and terminating RF transmission, selecting radio channel or frequency, and monitoring operational status of the transceiver. The signal generator is also capable of interactive communication with external third-party digital radio dispatch console systems via Ethernet network and TCP/IP protocol via an isolated network interoperability interface that implements a simple Application Program Interface (API).

Systems and methods described herein provide improved access to wireless devices in Power Saving Mode (PSM) and extended Discontinuous Reception (eDRX) sleep. A mobility management entity (MME) receives a wake-up time request for a wireless device, wherein the wake-up time request includes a designated wake-up time for the wireless device to receive data services. The MME device stores the designated wake-up time when the designated wake-up time is after a current tracking area update (TAU) window for the wireless device and receives, after the storing, a TAU request for the wireless device. The MME device sends, in response to the TAU request, a TAU response that includes the designated wake-up time.
