A portable terminal, providing a portable terminal operation system together with a controller that starts transmission of a connection standby packet when receiving a disconnection request and ends the transmission of the connection standby packet when receiving a connection request, includes: a disconnection request transmission device that transmits the disconnection request to the controller when notified that an application body of a first cooperative application shifts to a background in a case where a start request for a second cooperative application is generated while the first cooperative application is running; and a connection request transmission device that starts monitoring reception of the connection standby packet when notified that the second cooperative application has been started in a case where the start request is notified from the first cooperative application to the second cooperative application, and transmits the connection request to the controller when receiving the connection standby packet.

A method of operating a radio receiver device to monitor a paging group over a paging period. The paging group comprises one or more paging candidates, each having a respective repetition length. The method comprises: receiving one or more data symbols; attempting to decode said received data symbols, wherein a successful decoding attempt produces a decoded message comprising a value indicative of a respective repetition length of said decoded message; and, if the decoding attempt is successful, stopping monitoring of a paging candidate having a respective repetition length greater than said value before the end of the paging period.

A method for performing outer loop power control in wireless communications includes initializing a time interval clock to count down a predetermined time interval; receiving and decoding a channel quality indicator (CQI) message; computing a decision metric value for each symbol in the decoded CQI message; determining whether the CQI message is erroneous; counting a number of erroneous CQI messages; and signaling a wireless/transmit receive unit to adjust an uplink transmission power on a condition that the time interval clock has expired and the number of erroneous CQI messages exceeds a threshold.

Performing detection of a synchronization beacon. The UE may include a first radio which supports, e.g., simultaneously, a first radio access technology (RAT) and a second RAT. The UE may perform transmission according to the first RAT on the first radio with a base station. The UE may receive a request to perform a tune-away to detect a synchronization beacon on the second RAT. The synchronization beacon may repetitively occur in successive first time periods. The UE may repeatedly perform a search for the synchronization beacon in different sub-portions over successive first time periods. The search may be repeatedly performed until the synchronization beacon is located in a respective sub-portion of one of the successive time periods.

According to a first aspect there is presented a method for synchronization in a wireless device-to-device (D2D) based communications network as performed by a first wireless device. The method comprises identifying an attempt to make a network connection on a default sub-channel over a D2D communications interface from a second wireless device. The method comprises transmitting control information on the default sub-channel to the second wireless device, wherein the control information comprises an indicator of an operational sub-channel, and wherein the operational sub-channel is for subsequent D2D communication between the first wireless device and the second wireless device.

A communication device includes a receiving circuit and a start-up time adjustment circuit configured to transmit, to the receiving circuit, a start signal that instructs a change from a sleep state to an active state, wherein the start-up time adjustment circuit is configured to transmit, to the receiving circuit, a first start signal that instructs a change from the sleep state to the active state at a first time earlier than a second time when a first signal reaches the communication device, measure a first time difference between the second time and the first time, determine, based on the first time difference, a third time when the receiving circuit is changed from the active state to the sleep state, and transmit a second start signal that instructs a change from the sleep state to the active state to the receiving circuit at the third time.

A system, method, and computer program product are provided for intelligent radio state switching for geographically fixed access points. In use, a location associated with a mobile device is determined, using minimal energy drain on a battery of the mobile device. Additionally, it is determined whether the location is associated with a known desired geographical area for accessing at least one communication network. Further, at least one transceiver of the mobile device is turned on for accessing the at least one communication network when it is determined that the location is associated with the known desired geographical area.

Embodiments of this disclosure disclose an information determining method and user equipment. The method includes: monitoring a target channel or a target signal to acquire a first characteristic, where the first characteristic is a characteristic of the target channel or the target signal; and determining first information based on the first characteristic, where in a case that the target channel or the target signal is used to indicate a first power-saving mode of the UE, the first information is a second power-saving mode of the UE; or in a case that the target channel is used to indicate whether the UE monitors a PDCCH associated with the target channel, or the target signal is used to indicate whether the UE monitors a PDCCH associated with the target signal, the first information is a second characteristic of the PDCCH or the second power-saving mode of the UE.

Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to ultra low-power paging frames for wake up and discovery. One example apparatus for wireless communications generally includes at least one interface configured to receive via a first radio and a second radio, wherein the at least one interface receives a paging frame from another apparatus via the second radio while the first radio is in a first power state that is lower than a second power state of the second radio; and a processing system configured to take one or more actions based on a command field included in the paging frame.
