摘要:
A mobile station (MS) to determine signal quality values is disclosed. The MS may include a transmitter and a receiver and the receiver may determine a signal power value, a noise power value, and an interference power value of a signal received from antennas. The receiver may determine the signal power value and the interference value using a second preamble included in a super-frame of the signal, wherein the second preamble includes cell information. The receiver may determine a noise power value of the signal received from the plurality of antennas using unoccupied orthogonal frequency division multiple access (OFDMA) tones of a first preamble included in the super-frame of the signal, wherein the first preamble includes carrier information. The receiver may also use the fractional frequency reuse (FFR) and MIMO features to determine signal quality values using the signal power value, the noise power value, and the interference power value.
摘要:
Embodiments of an eNB and method of transmitting PDCCHs are generally described herein. In some embodiments, the eNB may be configured to transmit PDCCHs that are based on a UE-specific reference signal (i.e., a UE-RS). In these embodiments, the UEs may be able to demodulate their PDCCH using a demodulation reference signal (DM-RS) that is specific to the UE (e.g., instead of a common reference signal). The PDCCHs disclosed herein may be suitable the Uu interface of an LTE-A system.
