A radio resource scheduler at a first base station may be configured to: identify radio frequency resources in use by the first base station, identify radio frequency resources to be reserved as virtual guard bands to reduce adjacent band interference, and install virtual guard band rules for reducing interference with adjacent bands. The virtual guard band information may be hints, allocations, priorities, reservations, or scheduling instructions for avoiding certain radio resources, radio resource blocks, or frequencies.

The present technology relates to a transmission apparatus capable of more flexibly realizing a plurality of multiplexing systems in the same broadcasting system, a transmission method, a reception apparatus, and a reception method.

A transmission apparatus generates a physical layer frame multiplexed in a predetermined multiplexing system and including determination information capable of determining a multiplexing system, and transmits the physical layer frame as a broadcasting signal. On the other hand, a reception apparatus receives a broadcasting signal, and determines a multiplexing system of a physical layer frame multiplexed in a predetermined multiplexing system on the basis of determination information included in the physical layer frame acquired from the broadcasting signal, and processes the physical layer frame. The present technology can be applied to transmission systems for terrestrial digital TV broadcasting systems, for example.

Methods, systems, and devices for wireless communication are described. A wireless device communicating critical or latency sensitive information may determine that a transmission has failed in a shared radio frequency (RF) spectrum band. The device may then transmit a silencing signal in a managed RF spectrum band, and switch to communicating in the managed band. Other wireless devices communicating with the first device may receive the silencing signal and may also switch to the managed RF spectrum band. Based on the silencing signal, user equipments (UEs) not associated with the critical communications and operating in the managed band may suspend transmissions, although they may still receive downlink (DL) data.

A WBAN system for real-time telemonitoring health of a subject, involving a wearable biosignal sensors, each sensor of the sensors configured to measure a plurality of biosignals, ultra-low-power radios correspondingly coupled with the sensors; and a processor operable with at least one of the sensors and the radios, each radio of the radios configured to receive the biosignals from each corresponding sensor and to transmit the biosignals to a processor via a WBAN, and the processor configured to: receive the biosignals from the radios, process the biosignals via a set of executable instructions storable in relation to a nontransitory memory device, the set of executable instructions comprising an instruction for synchronizing time of the biosignals by using the broadcasted R peak reference, whereby real-time health data is providable, and transmit the real-time health data to a healthcare provider.

In vehicular ad hoc networks (VANETs), vehicles communicate either with each other via vehicle-to-vehicle (V2V) communication or with stationary road side infrastructure or road side units (RSUs) via vehicle-to-infrastructure (V2I) communication, to exchange information generated by the mobile applications. Vehicular networks require a reliable and efficient one-hop broadcast service. A makeup strategy for vehicular networks, referred to as cooperative relay broadcasting (CRB), is described. Neighboring nodes rebroadcast the packet from a source node to increase the reliability of the broadcast service. The decision to perform CRB is taken proactively and based on the channel conditions between the relaying nodes and the target one-hop neighbors.

The invention relates to a method in a wireless device for mapping a logical channel to one of a first and a second link. The first link is maintained to a first radio network node and the second link is maintained to a second radio network node. The method comprises obtaining (910) information indicating to which of the first and the second links one or more of at least one logical channel is mapped. The method also comprises selecting (920) a logical channel among the at least one logical channel, and mapping (930) the selected logical channel to one of the first and the second links based on the obtained information. The invention also relates to a corresponding method in the first radio network node.
