Abstract: Pre-scaled orthogonal differential vector signalling (ODVS) techniques are described. The ODVS encoding schemes described herein generate one sub-channel for each bit by multiplying each bit by a different row in a transmitter encoding matrix to produce a set of sub-channels. Each wire carries a signal that is a superposition of elements from all of the sub-channels in the set. The transmitter encoding matrix is selected such that its rows (i.e. sub-channels) are mutual orthogonal. This means that the receiver can decode the signals received from all wires in concert to reliably recover the original bits. The transmitter encoding matrix is a Hadamard matrix in some cases. This disclosure is particularly focussed on ODVS techniques that apply a scaling factor, termed a ‘pre-scaler’, to a weaker sub-channel or sub-channels within the set of sub-channels so as to boost that/those sub-channel(s) relative to the other sub-channels.

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.
