Abstract: Beam-steered millimeter wave signals transmitted in each of n sector slices include a sequence of primary synchronization (PSCH) symbols within predetermined symbol positions in at least one slot of a subframe. The symbols in consecutive symbol positions are each transmitted on a different one of the n slices, with the first symbol repeated on the same slice at the end. The sequence order rotates cyclically in each subframe so that two PSCH symbols are transmitted on one slice in a single subframe every nth subframe. Secondary synchronization (SSCH) and Broadcast Channel (BCH) symbols are transmitted in a predetermined pattern following the sequence of PSCH symbols. By transmitting consecutive PSCH symbols on different slices and repeating the first symbol, the mobile station can detect the best slice and beam by switching receive beams every subframe instead of every slot, relaxing time constraints on AGC adjustment while avoiding the start-at-the-edge problem.

Abstract: Methods and apparatus for transmitting power setting information in a downlink Physical Downlink Shared Channel (PDSCH) in a communication system. In this communication system, a plurality of methods for calculating traffic-to-pilot ratios (T2P) are established. In addition, a mapping scheme between a plurality of overhead signals and a plurality of reference signal (RS) overhead ratios, ηRS, and the plurality of T2P calculation methods is established. A user-specific T2P ratio PB,k/PRS for certain OFDM symbols, a RS overhead ratio ηRS and a calculation method selected from the plurality of T2P calculation methods are assigned to a wireless terminal. Then, an overhead signal corresponding to both of the assigned RS overhead ratio ηRS and the assigned T2P calculation method is selected in accordance with the mapping scheme and is transmitted to the wireless terminal. In addition, the user-specific traffic-to-pilot ratio PB,k/PRS is transmitted to the wireless terminal. The wireless terminal may calculate the traffic-to-pilot ratios across different transmission antennas and different OFDM symbols in dependence upon the received traffic-to-pilot ratio PB,k/PRS, and the RS overhead ratio and the T2P calculation method indicated by the RS overhead signal.

In the TDM-first approach, at least one of a plurality of code blocks are assigned with a number of consecutive data carrying OFDM symbols. In the FDM-first approach, at least one of the plurality of code blocks are assigned with all of the data carrying OFDM symbols.
