Abstract: A first radio has duplex communication with a second radio and a third radio, without using a base station by using a multiple-access protocol system. The first radio is configured to switch back and forth between being a master radio and a slave radio in the multiple-access protocol system. In some embodiments, time-division multiplexing is used as the multiple-access protocol system for the first radio, the second radio, and the third radio to communicate. In some embodiments, the master radio provides timing synchronization and/or assigns transmission slots for radios in the multiple-access protocol system.

Abstract: The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and/or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and/or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs.

Abstract: Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (LTE) experiences enhanced signal reception and/or reduced interference. In order to optimally implement downlink CoMP, a serving cell needs to obtain channel state information (CSI) for the downlink channels from the multiple transmission points to the UE. This disclosure deals with radio resource control (RRC) signaling for configuring the UE to obtain and report CSI for those downlink channels.

Abstract: To maintain communications of uplink ACK/NACK signals even for a transition period during which the number of aggregated component carriers is added/removed by higher layer signaling, it is a feature providing a reception section that receives the PDSCH for each of CCs that constitute the system band, a demodulation section (406) that demodulates the received PDSCH of each of CCs, an ACK/NACK signal generating section (418) that generates an uplink ACK/NACK signal in response to a demodulation result of the PDSCH in the demodulation section (406), and a mapping section (415) that allocates radio resources to an uplink ACK/NACK signal of the anchor block using LTE, while allocating user-specific radio resources to uplink ACK/NACK signals of the other CCs.

Abstract: The embodiments disclosed herein provide a mechanism for sharing protection resources in an arbitrary network topology involving pre-computing the protection resources so that data-plane-based protection can be used to activate the protection resources upon detection of a failure, thus, providing faster switching times than typical control-plane-based solutions. This is accomplished by configuring a mesh network to include, for a working path in the network, one or more protection paths with the same end nodes as the working path, where each protection path includes at least one intermediate node that is not part of the working path. The intermediate node accepts a protection request from one of the end nodes and determines whether a local resource for a protection path is available.

Abstract: A router receives from a host service a message which is intended for delivery to a mobile device via a wireless network. The message includes an indication field which includes a return packet indication on whether to send a return packet to the host, an identifier field which includes an identifier which identifies the device, and a payload field which includes a payload of the message. When the indication is set to a first, setting and the message is not being delivered to the device, the router sends to the host a return packet which indicates that the message is not being delivered to the device. When the indication is set to a second setting and the message is not being delivered to the device, the router does not send to the host the return packet which indicates that the message is not being delivered to the device.
