Initializing reference signal generation in wireless networks |
摘要 |
A transmitting node uses different reference signal sequences for different types of enhanced control channels. An example method begins with generating (1410) a first reference signal sequence, from a first initialization value, and generating (1420) a second reference signal sequence, from a second initialization value. These reference signal sequences are associated with two corresponding enhanced control transmissions. A first enhanced control channel and reference symbols taken from the first reference signal sequence are transmitted (1430), using first time-frequency resources and a first set of transmission points or a first set of antenna ports or both, and a second enhanced control channel and reference symbols taken from the second reference signal sequence are also transmitted (1440), using a differing second set of transmission points and/or a differing second set of antenna ports and/or a differing second set of time-frequency resources, in the same subframe or group of subframes. |
