    摘要: A user equipment (UE) for time division duplex (TDD) communication through a wireless communication channel has a receiver to receive a channel state information reference signal (CSI-RS) subframe configuration value, a CSI-RS configuration value, and a CSI-RS; and circuitry to determine a subframe index corresponding to a temporal position of a special subframe including the CSI-RS; determine a CSI-RS pattern of one or more orthogonal frequency division modulation (OFDM) resource elements carrying the CSI-RS, the pattern being from among a group of CSI-RS patterns that include OF DM resource elements in OFDM symbols corresponding to a physical downlink control channel (PDCCH) region of a legacy LTE wireless communication channel; control the receiver to receive the special subframe carrying the CSI-RS during the temporal position and at the one or more OFDM resource elements of the CSI-RS pattern; and measure the wireless communication channel based on the CSI-RS.

    摘要: Techniques to manage heterogeneous carrier types are described. User equipment may comprise a processor circuit and a network control component for execution on the processor circuit to locate a synchronization signal (SS) and a cell-specific reference signal (CRS) in a physical resource block (PRB) pair of a long term evolution (LTE) system, the PRB pair having a physical signal pattern for a first carrier type, the physical signal pattern for the first carrier type to have a same number of defined positions between the SS and the CRS within the PRB pair as a physical signal pattern for a second carrier type. Other embodiments are described and claimed.

    摘要: An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may receive one or more physical broadcast channel (PBCH) signals, dependent on whether the UE is in a normal coverage mode or in one of the EC modes. The PBCH signal may be combined to form a combined PBCH signal, when the UE is in an EC mode, and decoded to determine one of a plurality of sets of resource regions associated different EC modes for communication with the eNB. The signal may be scrambled using a Radio Network Temporary Identifier (RNTI) dependent on at least one of a signal type of the control signal and the EC mode. Paging and the system information block (SIB) signals in a Physical Downlink Shared Channel (PDSCH) may be decoded without decoding a physical downlink control channel (PDCCH) signal associated with the PDSCH.
