In general, the subject matter described in this disclosure can be embodied in methods, devices, and program products for selecting a wireless transmission mechanism. A computing device receives a request to begin a full-duplex voice communication session with a remote computing system. The computing device identifies that it has wirelessly connected to both a WWAN access point and a WLAN access point. The computing device determines whether a level of non-voice session data that is queued for transmission or receipt by the computing device falls beneath a threshold level of data, and as a result, switches to using a single one of multiple WLAN radio chains. The computing device communicates data over the single one of the multiple WLAN radio chains, including voice session data from the full-duplex voice communication session.

A base phone and additional phone implementation method, and an Internet Protocol (IP) terminal. The implementation method includes acquiring, by the IP terminal, a group address, group-sending, by the IP terminal, a base phone query message according to the group address, and determining whether a base phone feedback message is received, and when the IP terminal receives the base phone feedback message fed back by a base phone, marking the IP terminal as an additional phone, and otherwise marking the IP terminal as a base phone, and registering with a server, and according to the implementation method the base phone and the additional phone are set up using IP terminals, which avoids disadvantages of a lack of security protection and proneness to theft when an analog phone is connected in a manner of physical parallel connection of copper cables, and therefore improves security significantly.

The present disclosure provides a method of setting reserved subframes for indication of a resource pool by a bitmap, a user equipment, and a base station. In the present disclosure, the resource pool is used for transmitting or receiving sidelink signals within a system frame number cycle that includes predefined subframes and remaining subframes that are subframes after excluding the predefined subframes within the system frame number cycle. In the method, a number of the reserved subframes is determined so that the bitmap is repeated by integer times within the subframes after excluding the reserved subframes and the predefined subframes within the system frame number cycle. In the method, position of each of the reserved subframes is set, wherein at most two reserved subframes are set per n subframes within the system frame number cycle.

A method includes sending, from a base unit, provisioning information to a first device. The provisioning information is associated with the first device establishing a connection with a network device. The method includes identifying a source of interference with the connection. The method also includes sending, to the first device, information indicating an operation state of the source of the interference.

The invention provides a method for synchronizing timing clocks in wireless communication, e.g. DECT based, between a timing master (P_l) and a timing slave (P_f). The timing master measures (MPD1) a phase offset between its internal clock and a reference clock, e.g. a network clock, e.g. IEEE 1588 over an Ethernet connection. Next, the timing master transmits (TPD1) data indicative of said measured phase offset to the timing slave or timing slaves, which also measure their phase offset between their internal clocks and the reference clock. Next, the timing slave(s) adjust (APD2) their phase offset between their respective internal clocks and the reference clock in response to the received data indicative of measured phase offset from the timing master. Thus, the timing slaves can ensure that they provides the same phase offset between their internal clocks and the reference clock as the timing master. Thus, DECT synchronization can be obtained in spite of a reference clock with a limited precision.

A method of wireless communication using time division duplex over widely spaced frequency bands by a communication device includes receiving millimeter wave band downlink signals comprising a plurality of first transmission time intervals (TTIs) and transmitting millimeter wave band uplink signals comprising at least one second TTI, wherein the number of first TTIs is greater than the number of second TTIs. The method includes receiving sub-7 GHz band downlink signals comprising at least one third TTI and transmitting sub-7 GHz band uplink signals comprising a plurality of fourth TTI, wherein the number of third TTIs is less than the number of fourth TTIs.

A method is disclosed for wireless density-based on-the-fly codec and radio frequency link type selection. The method includes storing a link quality value, and scanning a plurality of timeslots across a plurality of wireless carriers. The method also includes calculating, based on the scanning, an average radio frequency density level for a time period. Still yet, the method includes calculating a current density level based on the link quality value and the average radio frequency density level. Further, the method includes selecting, based on the current density level, a codec from a plurality of stored codecs. The selected codec is associated with a link type. Moreover, the method includes receiving a command to open a wireless link, and, in response to the command, opening the wireless link using the selected codec and the associated link type.
