JOINT CHANNEL ESTIMATION

摘要

In order to demodulate data received via a physical downlink shared channel, PDSCH, a client device may need to estimate the channel of the PDSCH. The channel estimate quantifies how physical phenomena, such as the Doppler shift, affect the data during wireless transmission. It is an object to provide a procedure for improving channel estimation in wireless radio communication. A client device may perform joint channel estimation for PDSCH data based on a PDSCH reference signal, RS, and the at least one further signal being: physical downlink control channel, PDCCH, data, a PDCCH RS, or PDSCH data. The client device may use the channel estimate to decode PDSCH data. A client device, a network access device, methods, and a computer program are described.
