摘要： Techniques for determining time of arrivals (TOAs) of signals in a wireless communication network are described. Each cell may transmit (i) synchronization signals on a set of contiguous subcarriers in the center portion of the system bandwidth and (ii) reference signals on different sets of non-contiguous subcarriers distributed across the system bandwidth. A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results.

摘要： A method signals a modulation scheme to user equipment on a control channel in a communication system. The method includes encoding the modulation scheme on a modulation specifier and encoding a number of channelization codes on a code group indicator. When the modulation scheme is other than quadrature phase shift keying with the user equipment being configured to support 64-quadrature amplitude modulation (64-QAM), then set the modulation specifier to indicate that the applied modulation scheme is other than QPSK, encode a code offset on a code offset indicator, and set one bit of the code offset indicator to indicate that the applied modulation scheme is 64-QAM. Finally, the method includes transmitting the modulation specifier, the code group indicator, and the code offset indicator on the control channel to the user equipment.

A base station (102, FIG. 1) transmits data codes (504, 604, 702, FIGS. 5-7) within a radio frame (300, FIG. 3). The data codes are Code Division Multiple Access (CDMA) data codes, in an embodiment. The base station also transmits a Time Division Multiplexed (TDM) synchronization code (502, 608, 706, FIGS. 5-7), in an embodiment. The base station discontinuously transmits (1004, FIG. 10) a portion of a radio frame slot that is coincident in time with a duration of the TDM synchronization code, in various embodiments. The discontinuously transmitted portion of the radio frame slot may include Transport Format Combination Indicator (TFCI) bits (510, FIG. 5), pilot bits (710, FIG. 7), or data bits (612, FIG. 6), in various embodiments. A base station's transmissions may be synchronous in time and frequency with the transmissions of other base stations.
