Abstract
A method and apparatus facilitating transmit diversity for control information communications is provided. The method may comprise processing received content, generating control information in response to the processed content, allocating two or more resources associated with two or more transmit antennas for transmitting the control information using a transmit diversity scheme, and determining cyclic shifts by applying a predetermined cyclic shift delta parameter.
Claims23
A method of facilitating transmit diversity for communications, the method comprising:
- processing received content;
- generating control information in response to the processed content;
- allocating two or more resources associated with two or more transmit antennas for transmitting the control information using a transmit diversity scheme;
- determining cyclic shifts by applying a predetermined cyclic shift delta parameter;
- assigning a first orthogonal cover (OC) for a first allocated resource and
- assigning a second OC for a second allocated resource when at least one unallocated OC is available, the at least one unallocated OC being determined based at least in part on a number of available cyclic shifts, a number of available OCs, a number of reference signal symbols, and a number of resources available for a reference signal.
A computer program product, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to process received content;
- program code to generate control information in response to the processed content;
- program code to allocate two or more resources associated with two or more transmit antennas for transmitting the control information using a transmit diversity scheme;
- program code to determine cyclic shifts by applying a predetermined cyclic shift delta parameter;
- program code to assign a first orthogonal cover (OC) for a first allocated resource;
- and
- program code to assign a second OC for a second allocated resource when at least one unallocated OC is available, the at least one unallocated OC being determined based at least in part on a number of available cyclic shifts, a number of available OCs, a number of reference signal symbols, and a number of resources available for a reference signal.
An apparatus, comprising:
- means for processing received content;
- means for generating control information in response to the processed content;
- means for allocating two or more resources associated with two or more transmit antennas for transmitting the control information using a transmit diversity scheme;
- means for determining cyclic shifts by applying a predetermined cyclic shift delta parameter;
- means for assigning a first orthogonal cover (OC) for a first allocated resource;
- and
- means for assigning a second OC for a second allocated resource when at least one unallocated OC is available, the at least one unallocated OC being determined based at least in part on a number of available cyclic shifts, a number of available OCs, a number of reference signal symbols, and a number of resources available for a reference signal.
A wireless communications device (WCD), comprising:
- at least one processor configured for:
- processing received content;
- generating control information in response to the processed content;
- allocating two or more resources associated with two or more transmit antennas for transmitting the control information using a transmit diversity scheme;
- determining cyclic shifts by applying a predetermined cyclic shift delta parameter;
- assigning a first orthogonal cover (OC) for a first allocated resource;
- and
- assigning a second OC for a second allocated resource when at least one unallocated OC is available, the at least one unallocated OC being determined based at least in part on a number of available cyclic shifts, a number of available OCs, a number of reference signal symbols, and a number of resources available for a reference signal.
