    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.

    摘要: Technology to provide conditional physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include computer circuitry configured to: Receive a downlink control channel within a prior specified subframe, wherein the prior specified subframe occurs in time before the subframe n; recognize a downlink control channel type received within the prior specified subframe is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); determine a PUCCH resource for the HARQ-ACK transmission using a lowest control channel element (CCE) index of the PDCCH when the received downlink control channel type is the PDCCH; and determine the PUCCH resource for the HARQ-ACK transmission using a lowest enhanced CCE (ECCE) index of the EPDCCH when the received downlink control channel type is the EPDCCH.
