A guard period for switching between uplink and downlink subframes is created by shortening an uplink subframe, i.e., by not transmitting during one or more symbol intervals at the beginning of the subframe interval. A grant message includes signaling indicating when a shortened subframe should be transmitted. An example method is implemented in a first wireless node configured to transmit data in transmit subframes occurring at defined subframe intervals and having a predetermined number of symbol intervals. This example method includes determining that a transmit subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, shortening transmission of the transmit subframe by not transmitting during a beginning portion of the subframe interval for the transmit subframe and transmitting during the remainder of the subframe interval.

The present disclosure relates to the wireless communication of information for a hearing assistance device including a multi-mode radio adapted to provide communications at different frequencies using frequency control. In applications of hearing aids, the processor is adapted to perform correction of sound for a hearing impaired user. In certain examples the present subject matter provides an inductive portion for inductive communications. In various applications the multi-mode radio can be used for long range and short range communications.

A Machine-to-machine (M2M) terminal (11) is configured to receive a first notification from a base station (13) and to transmit a second notification to the base station (13) when establishing a radio connection with the base station (13) after reception of the first notification or while performing a procedure for establishing a bearer between the M2M terminal (11) and a core network (14) after reception of the first notification. The first notification indicates whether specific coverage enhancement processing is supported in a cell (130) of the base station (13) in which the M2M terminal (11) is located. The second notification indicates that the specific coverage enhancement processing is required or being executed by the M2M terminal (11). It is thus possible to provide an improvement to allow the M2M terminal to determine necessity of special coverage enhancement processing for M2M terminals.

A transmitter can include a laser operable to output an optical signal; a digital signal processor operable to receive user data and provide electrical signals based on the data; and a modulator operable to modulate the optical signal to provide optical subcarriers based on the electrical signals. A first one of the subcarriers carriers carries first TDMA encoded information and second TDMA encoded information, such that the first TDMA encoded information is indicative of a first portion of the data and is carried by the first one of the subcarriers during a first time slot, and the second TDMA encoded information is indicative of a second portion of the data and is carried by the first one of the subcarriers during a second time slot. The first TDMA encoded information is associated with a first node remote from the transmitter and the second TDMA encoded information is associated with a second node remote from the transmitter. A second one of the subcarriers carries third information that is not TDMA encoded, the third information being associated with a third node remote from the transmitter. A receiver and system also are described.

A communication device is configured to communicate with an infrastructure equipment forming part of a mobile communications network, and to communicate with one or more relay nodes of the mobile communications network. The communications device comprises a receiver configured to receive signals on the downlink from the one or more relay nodes via a first wireless interface, and to receive signals on the downlink from the infrastructure equipment via second wireless access interface, a transmitter configured to transmit signals on the uplink to the one or more relay nodes via the first wireless access interface, and to transmit signals on the uplink to the infrastructure equipment via the second wireless access interface, and a controller configured to control the receiver to receive the signals and to control the transmitter to transmit the signals.

A method of securing wireless backhaul for a child base station in a first network provided by a first operator, including: any parent base station with wireline backhaul capability and configured to virtualise a core network User Plane Function, UPF, advertises that it supports a wireless backhaul service; the child base station in the first network connects over an air interface to one or more parent base stations in a second network provided by a second operator; the child base station sends a backhaul service request to a connected parent base station; when the backhaul service request is accepted, the connected parent base station uses a virtualised UPF to enable a direct wireline backhaul link between the parent base station and a data network; and the child base station uses the air interface as a wireless backhaul link and the wireline backhaul link of the connected parent base station for backhaul.

An exemplary embodiment is a temperature monitoring buffering sensor and system for applications ranging from food storage to temperature-controlled pharmaceuticals. The system includes a temperature sensor unit with a buffered temperature probe sensor contained in a housing with a Bluetooth® transmitter circuit. The sensor unit is battery operated and is self-contained without the need for wiring to provide power or signal flow. The sensor unit controller periodically sends out a transmitter beacon signal identifying the temperature sensor unit and the temperature sensed by the probe, as well as a battery condition. A base station is positioned close enough to be in range of the transmitter beacon signal and includes an RF receiver circuit configured to receive the RF transmitter beacon signal from the sensor unit, and a processor configured to monitor and analyze data received by the RF receiver circuit.

Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.

In a first aspect, a method of wireless communication includes receiving, by a user equipment (UE) from a first network entity, a multiple component carrier (CC) signaling message including multiple CC scheduling information. The method also includes receiving, by the UE from, a downlink control information transmission indicating a downlink control information indication for multiple CCs, and determining a first downlink control information parameter for a first CC and a second downlink control information parameter for a second CC based on the downlink control information indication and the multiple CC scheduling information. The method further includes receiving, from the first network entity, a first downlink transmission for the first CC based on the first downlink control information parameter, and receiving, from a second network entity, a second downlink transmission for the second CC based on the second downlink control information parameter. In other aspects, uplink transmissions may be sent.
