METHOD FOR TRANSMITTING REFERENCE SIGNALS
First Claim
1. A method of reference signal transmission in resource blocks (RBs) supporting multiple antenna port transmission in a wireless communication system, comprising:
- determining a first and a second mutually exclusive sets of RBs, at least one broadcast channel (BCH) being provided in RBs belonging to said first set of RBs;
transmitting a number of reference signals (RSes) only in at least one RB belonging to said second set of RBs when there is a conflict between transmitting said number of RSes and providing said broadcast channel,wherein each RB comprises at least one resource elements (REs).

Abstract
A method and apparatus for transmitting reference signals in a wireless communication system is disclosed. The method and apparatus includes reference signal, RS, transmission in resource blocks supporting multiple antenna port transmission, at least one broadcast channel being provided in resource blocks belonging to a first set of resource blocks, a first number of reference signals being transmitted in at least one resource block supporting multiple antenna port transmission and a second number of reference signals being transmitted in at least one resource block belonging to a second set of resource blocks. Preferably, different resource elements, REs, are used for each reference signal in resource blocks. An example embodiment of reference signal support of, e.g., eight antenna ports is provided.

16. A method of reference signal transmission in resource blocks (RBs) supporting multiple antenna port transmission in a wireless communication system, comprising:
-
determining a first and a second mutually exclusive sets of RBs, at least one synchronization signal (SS) being provided in RBs belonging to said first set of RBs; and transmitting a number of reference signals (RSes) only in at least one RB belonging to said second set of RBs when there is a conflict between transmitting said number of RSes and providing said SS, wherein said at least one SS is a primary synchronization signal (P-SS), or a secondary synchronization signal (S-SS), wherein each RB comprises at least one resource elements (REs). - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
