Abstract
A method of wireless communication includes configuring a virtual SRS (sounding reference signal) transmission to prompt a user equipment (UE) to use a shortened uplink transmission format to create a silent period at an end of a subframe. Reports are received from the UE indicating interference observed during the silent period.
Claims20
A method for inter-cell interference control (ICIC), comprising:
- configuring a virtual SRS (sounding reference signal) transmission to prompt a user equipment (UE) to use a shortened uplink transmission format and creating a silent period at an end of a subframe;
- and
- receiving, from the UE, reports of interference observed during the silent period.
A method for inter-cell interference control (ICIC), comprising:
- receiving a virtual SRS (sounding reference signal) configuration instructing a user equipment (UE) to use a shortened uplink transmission format in a subframe while not transmitting an SRS during the subframe and creating a silent period at an end of the subframe;
- and
- measuring interference during the silent period.
A apparatus for wireless communication, comprising:
- means for configuring a virtual SRS (sounding reference signal) transmission to prompt a user equipment (UE) to use a shortened uplink transmission format and creating a silent period at an end of a subframe;
- and
- means for receiving, from the UE, reports of interference observed during the silent period.
A apparatus for wireless communication, comprising:
- means for receiving a virtual SRS (sounding reference signal) configuration instructing a user equipment (UE) to use a shortened uplink transmission format in a subframe while not transmitting an SRS during the subframe and creating a silent period at an end of the subframe;
- and
- means for measuring interference during the silent period.
A computer program product for wireless communication in a wireless network, comprising:
- a computer-readable medium having a program code recorded thereon, the program code comprising:
- program code to configure a virtual SRS (sounding reference signal) transmission to prompt a user equipment (UE) to use a shortened uplink transmission format and creating a silent period at an end of a subframe;
- and
- program code to receive, from the UE, reports of interference observed during the silent period.
A computer program product for wireless communication in a wireless network, comprising:
- a computer-readable medium having a program code recorded thereon, the program code comprising:
- program code to receive a virtual SRS (sounding reference signal) configuration instructing a user equipment (UE) to use a shortened uplink transmission format in a subframe while not transmitting an SRS during the subframe and creating a silent period at an end of the subframe;
- and
- program code to measure interference during the silent period.
A system for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to configure a virtual SRS (sounding reference signal) transmission to prompt a user equipment (UE) to use a shortened uplink transmission format and creating a silent period at an end of a subframe;
- and
- to receive, from the UE, reports of interference observed during the silent period.
