Patent ID: 8320267

Claim:
A wireless terminal (UE) operating in a time division duplex (TDD) mode, comprising: a transceiver; a processor coupled to the transceiver, the UE configured to receive a sounding reference signal (SRS) bandwidth (BW) assignment assigning the UE a maximum SRS BW size supported by a particular SRS BW signaling index configuration; the UE configured to transmit a plurality of sounding reference signals, at least one of the sounding reference signals is transmitted in a corresponding uplink pilot time slot (UpPTS) region of a special sub-frame of a radio frame, the radio frame including at least one uplink sub-frame, at least one downlink sub-frame, and the at least one special sub-frame, an uplink bandwidth comprising resource blocks (N RB UL ) wherein each resource block comprises a plurality of sub-carriers in the frequency dimension, wherein, in the frequency dimension, an uplink BW center is misaligned with a BW center of the SRS in the UpPTS region, and the sounding reference signal transmitted in the UpPTS region using a maximum SRS BW size in number of resource blocks having a largest value that is an even number of resource blocks with prime factors from a set of {2, 3, 5}, and is less than or equal to (N RB UL −6·N RA ) where N RA is a number of Random Access Channel (RACH) opportunities in the UpPTS region.
