Abstract
Methods, systems, devices, and apparatuses for wireless communications that support transmission diversity enhancement for uplink control channel are described. Generally, the described techniques provide for enhanced performance of an uplink control channel such as a physical uplink control channel (PUCCH) through the use of transmission diversity. In some cases, multiple input multiple output (MIMO) techniques may be supported for transmission of an uplink control channel for a given format suitable for transmission diversity enhancement. A resource block (RB) used in an uplink control channel transmission may contain a number of resource elements (REs) across one or more resource blocks. According to some aspects, a transmit diversity scheme may be employed at the RE level through application of different spatial precoders for different groups of REs of a given RB.
