System information and paging monitoring for multiple synchronization signal blocks
A configuration to enable a UE to select a new CSS set to use for monitoring for PDCCH based on changing conditions at the UE. The apparatus may receive, from a base station, a first indication of a search space for monitoring for a channel for at least one of system information, paging, or user data. A first set of monitoring occasions based on the search space indicated by the base station. The apparatus may determine a second set of monitoring occasions different than the first set of monitoring occasions based on a condition experienced by the apparatus. The apparatus may monitor for the channel based on the second set of monitoring occasions determined by the apparatus.

Transmission method, transmission apparatus, reception method and receiver apparatus
Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.
