METHOD OF INDICATING NUMBER OF ANTENNAS IN NETWORK BROADCAST SYSTEM
First Claim
1. A method for generating a broadcast signal, the method comprising:
- forming an information block for transmission, the information block comprising a first field comprising a plurality of bits configured to impart information to a first group of user equipment (UEs) regarding a first evolved NodeB (eNodeB) transmit antenna configuration;
generating error detection bits based upon the information block;
scrambling the error detection bits using a mask according to a second eNodeB transmit antenna configuration, wherein the mask is configured to impart information to a second group of UEs regarding the second eNodeB transmit antenna configuration;
generating the broadcast signal comprising the information block and the scrambled error detection bits; and
transmitting the generated broadcast signal via a packet broadcast control channel.

Abstract
A method for generating a broadcast signal includes forming an information block for transmission, the information block including a first field comprising a plurality of bits configured to impart information to a first group of user equipment (UEs) regarding a first evolved NodeB (eNodeB) transmit antenna configuration. The method further includes generating error detection bits based upon the information block and scrambling the error detection bits using a mask according to a second eNodeB transmit antenna configuration, such that the mask is configured to impart information to a second group of UEs regarding the second eNodeB transmit antenna configuration. The method also includes generating the broadcast signal having the information block and the scrambled error detection bits, and transmitting the generated broadcast signal via a packet broadcast control channel.
