Abstract:
A base station for secondary-cell (S-cell) operation in an unlicensed band is subject to listen-before-talk (LBT) rules. The apparatus generates S-cell discovery reference signal (DRS) that includes a primary synchronization signal (PSS) based on a cell ID associated with the base station, a secondary synchronization signal (SSS), a cell-specific reference signal (CRS), and optionally CSI-RS. Solutions are described for generating portions of the DRS to accommodate the placement of the DRS in arbitrary subframes.

Claim (Index 28):
An apparatus for an E-Node B (eNB), the eNodeB configured for Licensed-Assisted Access (LAA) to operate in an unlicensed band and apply Listen-Before Talk (LBT) before performing a transmission in the unlicensed band, the apparatus comprising:\n memory; and processing circuitry to configure the eNB for secondary cell operation in the unlicensed band, wherein as part of the secondary cell operation, the processing circuitry is configured to:\n generate a length-62 sequence for a secondary synchronization signal (SSS), the length-62 sequence comprising an interleaved combination of two length-31 binary sequences, wherein to generate the length-62 sequence, the processing circuitry is configured to:\n scramble a first length-31 binary sequence s0 with a scrambling sequence c0, to generate a scrambled sequence s0c0; \n scramble the sequence s0 with a scrambling sequence c1 and a first z1 scrambling sequence, to generate a scrambled sequence s0c1z1; \n scramble a second length-31 binary sequence s1 with the scrambling sequence c0, to generate a scrambled sequence s1c0; \n scramble the sequence s1 with the scrambling sequence c1 and a second z1 scrambling sequence, to generate a scrambled sequence s1c1z1; and \n for transmission of the SSS in any of subframes 0, 1, 2, 3, and 4 of a radio frame, interleave the scrambled sequence s0c0 with the scrambled sequence s1c1z1, wherein the scrambled sequence s0c0 resides in even positions d(2n) of the length-62 sequence and the scrambled sequence s1c1z1 resides in odd positions d(2n+1) of the length-62 sequence, and \n \n for transmission of the SSS in any of subframes 5, 6, 7, 8, and 9 of the radio frame, interleave the scrambled sequence s1c0 with the scrambled sequence s0c1z1, wherein the scrambled sequence s1c0 resides in even positions d(2n) of the length-62 sequence and the scrambled sequence s0c1z1 resides in odd positions d(2n+1) of the length-62 sequence; \n select any one subframe group of a plurality of subframe groups, the plurality of subframe groups including {0, 5}, {1, 6}, {2, 7}, {3, 8} and {4, 9}, wherein each subframe group includes two subframes of the radio frame; and generate signaling to configure transceiver circuitry to transmit the length-62 sequence as the SSS in two subframes of any one of the subframe groups, and wherein the memory is configured to store the sequence s0 and the sequence s1.
