The EPDCCH candidates may include EPDCCH candidates for the first serving cell and EPDCCH candidates for a second serving cell scheduled by the first serving cell.

Abstract: Link speed negotiation for 64 Gbps is done at 32 Gbps to allow only two speeds to be used during link state negotiation. The desire for 64 Gbps operation is indicated in a field shared during link state negotiation. After link speed negotiation is completed at 32 Gbps, a determination is made whether 32 or 64 Gbps operation is desired. If 32 Gbps operation is desired, procedures continue as in the prior operations. If 64 Gbps operation is desired, a new procedure is performed. The new procedure provides time for the optical transceiver to changeover from the PAM2 (pulse amplitude modulation) or binary operation used in 32 Gbps operation to the PAM4 multi-level operation used in 64 Gbps operation. After determining that the optical transceiver is ready to transmit, transmitter training is performed, with increased handshaking to provide improved granularity. After transmitter training is complete, conventional link initialization is performed.

Co-channel interference caused in the non-serving cell to the UE can be well suppressed or cancelled, and performance of the UE in demodulating a PDSCH can be better improved.

Abstract: A system and method that enforces one or more policy rules on user-allocated bandwidth portions of the overall system bandwidth, for example in an optical fiber transmission system.

Abstract: Information on allocation of a bandwidth of uplink communication of each user device is extracted from information notified by an upper-level device on the uplink communication of the user devices. Identification information of a lower-level device connected to a terminal device and identification information of the user devices are stored in correlation with each other. A bandwidth demanded for uplink communication of the terminal device is determined on the basis of the information on the allocation of the bandwidth of the uplink communication of each of the user devices and the identification information of the user devices. A start time point of the uplink communication of the terminal device and the amount of information of signals for which transmission of the uplink communication of the terminal device is allowed are allocated to the terminal device on the basis of the bandwidth demanded for the uplink communication of the terminal device.

Abstract: Technology for a user equipment (UE) to report periodic channel state information (CSI) is disclosed. The UE can generate a plurality of CSI reports for serving cells for transmission in a subframe. Each CSI report can correspond to a physical uplink control channel (PUCCH) reporting type among a plurality of CSI processes having a CSI process index (CSIProcessIndex) and a serving cell index (ServCellIndex). The UE can determine different priorities corresponding to each of the plurality of PUCCH reporting types. The UE can drop CSI reports corresponding to all CSI processes except a CSI process having the lowest CSIProcessIndex. The UE can drop CSI reports corresponding to all ServCellIndexes except a CSI report with the lowest ServCellIndex. The UE can multiplex at least one non-colliding CSI report from among CSI reports that are not dropped and hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback bits for transmission to an eNodeB.
