Apparatus and methods for wireless channel sounding

摘要

A technique of operating a wireless communication device includes receiving an assigned starting point index and an assigned reference signal bandwidth for a reference signal. The reference signal is then transmitted multiple times, beginning at an initial resource block that is associated with the assigned starting point index and in accordance with the assigned reference signal bandwidth, across a shared channel.

主权项

1. A wireless communication apparatus, comprising:
a transmitter apparatus configured to transmit:
an assigned starting point index and an assigned reference signal bandwidth for a reference signal;a hopping pattern parameter; anda total bandwidth assigned to a physical uplink shared channel, wherein the total bandwidth is configured to change over time on a semi-static basis, and wherein the physical uplink shared channel is configured to:
expand based on a contraction of an uplink control channel; andcontract based on an expansion of the uplink control channel;wherein the physical uplink shared channel and the uplink control channel are included in an uplink channel; and a receiver apparatus configured to receive multiple times, beginning at an initial resource block that is associated with the assigned starting point index and in accordance with the assigned reference signal bandwidth, the reference signal across the physical uplink shared channel.
