Abstract: A CU (Central Unit) executes scheduling for allocating radio resources of RRUs (Remote Radio Units) to radio transmission of downlink data while broadcasting, to DMs (Data Managers) via MFH, downlink data from MBH. Each DM selects, based on an allocation result obtained by scheduling, the downlink data of an RRU (Remote Radio Unit) corresponding to the self DM from the accumulated downlink data from the CU, and transfers the selected downlink data to the corresponding RRU while discarding the downlink data of other RRUs. Based on the allocation result, each RRU performs radio transmission of the downlink data from the DM to a corresponding UE (User Equipment) using the designated radio resource. This makes it possible to efficiently transfer the downlink data from the CU to each RRU via the MFH constructed by a TDM system represented by TDM-PON.

Abstract: Detection of the congestion on a link based on an exchange of messages between a sender and a receiver, one sender and several receivers or several senders and one receiver. This equipment is connected to the ends of a transmission channel. One of the items of equipment is designated as the master and the others slaves. These exchanges are aimed at enabling the master to calculate and compare the rate of the data send and the rate of the data received. A divergence in the rates calculated reveals a congestion on the link. All these exchanges are made in the application layer and therefore do not involve the underlying layers.

Abstract: A method for transmitting a signal by a Device-to-Device (D2D) User Equipment (UE) is disclosed. The method includes mapping a block of complex-valued symbols to Physical Resource Blocks (PRBs), and generating and transmitting a Single Carrier Frequency Division Multiple Access (SC-FDMA) signal after the mapping. If frequency hopping is used during the mapping, a lowest PRB index of the PRBs is changed between a first PRB index and a second PRB index according to a change in a transmission number for a transport block. If the block of complex-valued symbols is a D2D communication signal, the transmission number for the transport block is replaced with a subframe index of a D2D resource pool.
