    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: A Second Synchronous Signal (SSS) for a 3GPP LTE downlink signal is generated in such a way that a legacy User Equipment (UE) can determine whether the downlink signal comprises a legacy downlink signal or a New Carrier Type (NCT) downlink signal, which is unavailable to a legacy UE. One exemplary embodiment provides that a first binary sequence and a second binary sequence are generated in which the first and second binary sequences are part of the SSS for the downlink signal. The first binary sequence is multiplied by a first scrambling sequence, and the second binary sequence by a second scrambling sequence in which the first and second scrambling sequences are selected to indicate that the downlink signal is a new carrier type downlink signal. Other exemplary embodiments provide that an order of the first and second scrambling sequences indicates whether the downlink signal is a NCT downlink signal.
