Abstract
In a wireless communication system unused resource elements are utilized to transmit additional pilot and control signals. The additional pilot and control signals may mitigate the impact of interference. The unused resource elements may be in a downlink pilot timeslot (DwPTS) in a time division duplex system.
Claims36
A method for wireless communications, comprising:
- identifying resource elements not used in a subframe;
- and
- utilizing the unused resource elements to transmit at least one of additional pilot signals and control signals.
An apparatus for wireless communication, the apparatus comprising:
- means for identifying resource elements not used in a subframe;
- and
- means for utilizing the unused resource elements to transmit at least one of additional pilot signals and control signals.
A computer program product configured for wireless communications in a wireless network, the computer program product comprising:
- a computer-readable medium having program code recorded thereon, the program code comprising:
- program code to identify resource elements not used in a subframe;
- and
- program code to utilize the unused resource elements to transmit at least one of additional pilot signals and control signals.
An apparatus configured for wireless communication, the apparatus comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured:
- to identify resource elements not used in a subframe;
- and
- to utilize the unused resource elements to transmit at least one of additional pilot signals and control signals.
A method for wireless communications, comprising:
- receiving at least one of additional pilot signals and control signals on downlink resource elements previously identified by an eNodeB as being available in a subframe.
An apparatus configured for wireless communication, the apparatus comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured:
- to receive at least one of additional pilot signals and control signals on downlink resource elements previously identified by an eNodeB as being available in a subframe.
A computer program product configured for wireless communications in a wireless network, the computer program product comprising:
- a computer-readable medium having program code recorded thereon, the program code comprising:
- program code to receive at least one of additional pilot signals and control signals on downlink resource elements previously identified by an eNodeB as being available in a subframe.
An apparatus for wireless communications, comprising:
- means for receiving at least one of additional pilot signals and control signals on downlink resource elements previously identified by an eNodeB as being available in a subframe;
- and
- means for decoding the at least one of additional pilot signals and control signals.
