The purpose is to estimate a selection interval of transmission slots of other stations. A TDMA communication device may include a receiver, an estimating information acquirer, and a selection interval estimator. The receiver may receive communication data from another station through any of a plurality of reception slots within a selection interval set based on a given nominal increment. The estimating information acquirer may acquire estimation information for an estimated selection interval of another station based on the communication data received from another station. The selection interval estimator may estimate the estimated selection interval based on the estimation information.

A method for a transmission-side device to transmit a signal in a wireless communication system is disclosed. To this end, the transmission-side device forms a multiplexed block by multiplexing a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH) signal in time and frequency domains, wherein the PSS and the SSS form a synchronization signal (SS) by being multiplexed by the time-division multiplexing (TDM) method, and the SS and PBCH signals form the multiplexed block by being multiplexed by the TDM or frequency-division multiplexing (FDM) method.

A method and wireless station for receiving signals. The wireless station receives, from a base station, a control signal on a first subframe indicated as a downlink (DL) subframe by a time division duplex (TDD) uplink-downlink (UL-DL) subframe configuration. The control signal includes first information indicating that at least one UL subframe indicated by the TDD UL-DL subframe configuration is reconfigured as a TDD DL subframe. The wireless station receives, from the base station, DL data on a second subframe which was indicated as a TDD UL subframe by the TDD UL-DL subframe configuration but is currently reconfigured as a TDD DL subframe by the control signal. The wireless station transmits, to the base station, UL data on a TDD UL subframe except for being reconfigured as the TDD DL subframe by the control signal.

A method is disclosed for PHICH resource allocation in a wireless communication system that supports flexible TDD UL-DL configuration and in which different TDD UL-DL configurations are available and the TDD UL-DL configuration used by first UEs which operate according to the flexible TDD configuration can be different to the TDD UL-DL configuration used by second UEs which operate according to a long term TDD UL-DL configuration. The method comprising allocating a PHICH resource for both first UEs and second UEs according to LTE timing rules applicable to the TDD UL-DL configuration in use by second UEs.

An example data structure for managing user equipment communications in a wireless communications system is presented, as well as methods and apparatuses configured to implement the data structure. For instance, the data structure may include a downlink subframe comprising two slots and including one or more quick downlink channels having a single-slot transmission time interval. In addition, the example data structure may include one or more resource element blocks each comprising one or more resource elements into which a frequency bandwidth is divided within one or both of the two slots, wherein each of the one or more resource element blocks comprises a control channel region or a data channel region. Furthermore, the example data structure may include one or more resource grants, located within one or more control channel regions, for one or more user equipment served by the one or more quick downlink channels.

A bufferless ring network including at least two nodes and at least two timeslots, the at least two timeslots include a dedicated timeslot, and a first node in the bufferless ring network has use permission for the dedicated timeslot. The first node is configured to, in a state of having the use permission for the dedicated timeslot, detect whether all dedicated timeslots that pass through the first node are available, set a permission switch signal, and cancel the use permission for the dedicated timeslot according to the permission switch signal after detecting that all the dedicated timeslots that pass through the first node are available. A remaining node in the bufferless ring network is configured to obtain the use permission for the dedicated timeslot according to the permission switch signal. The remaining node is a node that needs to use the dedicated timeslot.

Among serial communication systems between vehicle-mounted communication units, a serial communication system for improving use efficiency of a communication bandwidth in a communication standard LIN has been required. In order to solve this problem, in a serial communication system of LIN, a response of a master node as a write request transmitted from the master node to a slave node and a response of the slave node transmitted from the slave node to the master node are combined into a time base, and a certain period for receiving a response from the slave node is provided after the write request from the master node.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a CIC value field in signaling information of a communication to provide an identification of the ingress network to an egress or receiving network of a long distance telecommunications network. The system and method provides for the provisioning of a signaling CIC for an ingress trunkgroup or network to a telecommunications network for downstream signaling purposes by overriding a received CIC value with a provisioned CIC value specific to the ingress network. This provisioned CIC value identifies the ingress network to the long distance network to the egress network for use by the egress network.
