Transmission and reception of discovery signals over a radio frequency spectrum band

摘要

Techniques are described for wireless communication. A first method includes receiving a first orthogonal frequency division multiplexing (OFDM) symbol including a plurality of reference signals (RSs) over a radio frequency spectrum band. The first method may also include receiving a second OFDM symbol including a first synchronization signal over the radio frequency spectrum band. A second method includes transmitting a first OFDM symbol including a plurality of RSs over an radio frequency spectrum band. The second method may also include transmitting a second OFDM symbol including a first synchronization signal over the radio frequency spectrum band. In each method, a first portion of the first OFDM symbol includes a higher density of the RSs than a remaining portion of the first OFDM symbol, and when included, the second OFDM symbol may be adjacent in time to the first OFDM symbol.

主权项

1. A method for wireless communication, comprising:
performing, by a base station, a clear channel assessment (CCA); and transmitting, by the base station, a first orthogonal frequency division multiplexing (OFDM) symbol comprising a plurality of reference signals (RSs) over a radio frequency spectrum band, wherein a first portion of the first OFDM symbol comprises a higher density of the RSs than a remaining portion of the first OFDM symbol; and wherein the transmission of the first OFDM symbol is based on a success of the CCA.
