Abstract
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.
Claims21
A method of operating a wireless communication device, comprising:
- receiving an assigned starting point index and an assigned reference signal bandwidth for a reference signal;
- and
- transmitting 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 a shared channel.
A method of operating a wireless communication device, comprising:
- transmitting an assigned starting point index and an assigned reference signal bandwidth for a reference signal;
- and
- receiving 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 a shared channel.
A wireless communication device, comprising:
- a scheduler configured to:
- assign a starting point index and an assigned reference signal bandwidth for a reference signal;
- and
- a transceiver coupled to the scheduler, wherein the transceiver is configured to:
- transmit the assigned starting point index and the assigned reference signal bandwidth for the reference signal;
- and
- 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 a shared channel, wherein the reference signal is a sounding reference signal.
A method of operating a wireless communication device, comprising:
- receiving an assigned starting point index and an assigned reference signal bandwidth for a reference signal;
- and
- transmitting, 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 at least a configured portion of a physical uplink shared channel, wherein the initial resource block is determined from floor(k*(NSCH/NSP)), where k corresponds to the assigned starting point index, NSCH corresponds to a number of total resource blocks in the physical uplink shared channel, and NSP corresponds to a number of total starting point indices which is determined from floor(NSCH/NBW1), and where NBW1 corresponds to a number of resource blocks in a narrowest reference signal bandwidth which is less than or equal to the assigned reference signal bandwidth.
