Abstract
A method, apparatus and computer program product are provided for conveying information regarding the antenna configuration and/or the transmission diversity scheme to a recipient, such as a mobile device. In particular, information regarding the antenna configuration and/or the transmission diversity scheme can be conveyed by appropriately mapping a physical broadcast channel within a sub-frame so as to include reference signals indicative of different antenna configurations or transmission diversity schemes. Alternatively, masking, such as cyclic redundancy check masking, can be used to provide information regarding the antenna configuration and/or the transmission diversity scheme.
Claims18
A method comprising:
- obtaining a bit mask based upon at least one of a number of antennas or a transmission diversity scheme;
- and
- scrambling a plurality of cyclic redundancy check bits to be transmitted with the bit mask to thereby impart information regarding at least one of the number of antennas or the transmission diversity scheme.
An apparatus comprising at least one processor and at least one memory including computer program instructions, the at least one memory and the computer program instructions configured to, with the at least one processor, direct the apparatus at least to:
- obtain a bit mask based upon at least one of a number of antennas or a transmission diversity scheme;
- and
- scramble a plurality of cyclic redundancy check bits to be transmitted with the bit mask to thereby impart information regarding at least one of the number of antennas or the transmission diversity scheme.
A method comprising:
- analyzing a plurality of bits that were received to determine which one of a plurality of predefined bit masks has been used to scramble cyclic redundancy check bits;
- and
- determining at least one of a number of antennas or a transmission diversity scheme based upon the respective bit mask that is determined to have been used to scramble the cyclic redundancy check bits.
An apparatus comprising at least one processor and at least one memory including computer program instructions, the at least one memory and the computer program instructions configured to, with the at least one processor, direct the apparatus at least to:
- analyze a plurality of bits that were received to determine which one of a plurality of predefined bit masks has been used to scramble cyclic redundancy check bits, said processor also configured to determine at least one of a number of antennas or a transmission diversity scheme based upon the respective bit mask that is determined to have been used to scramble the cyclic redundancy check bits.
A method comprising:
- selecting a cyclic redundancy check generator based upon at least one of a number of antennas or a transmission diversity scheme;
- and
- generating, using the selected cyclic redundancy check generator, a plurality of cyclic redundancy check bits to be transmitted to thereby impart information regarding at least one of the number of antennas or the transmission diversity scheme.
An apparatus comprising at least one processor and at least one memory including computer program instructions, the at least one memory and the computer program instructions configured to, with the at least one processor, direct the apparatus at least to:
- select a cyclic redundancy check generator based upon at least one of a number of antennas or a transmission diversity scheme;
- and
- generate, using the cyclic redundancy check generator selected, a plurality of cyclic redundancy check bits to be transmitted to thereby impart information regarding at least one of the number of antennas or the transmission diversity scheme.
A method comprising:
- analyzing a plurality of bits that were received to determine which one of a plurality of predefined cyclic redundancy check generators has been applied to the bits;
- and
- determining at least one of a number of antennas or a transmission diversity scheme based upon the respective cyclic redundancy check generator that is determined to have been applied to the bits.
An apparatus comprising at least one processor and at least one memory including computer program instructions, the at least one memory and the computer program instructions configured to, with the at least one processor, direct the apparatus at least to:
- analyze a plurality of bits that were received to determine which one of a plurality of predefined cyclic redundancy check generators has been applied to the bits;
- and
- determine at least one of a number of antennas or a transmission diversity scheme based upon the respective cyclic redundancy check generator that is determined to have been applied to the bits.
