Abstract
Suppression of serving cell transmissions directed to second-served UEs may improve channel estimation of a serving cell or a neighbor cell. This may include using scheduling information for second-served UEs to suppress serving cell signals intended for second-served UEs having overlapping MIMO transmissions. Alternatively, this scheduling information may aid in suppressing a serving cell signal for a second-served UE to improve channel estimation of a neighbor cell. Various embodiments described herein, include implementations and techniques to aid channel estimation, and signal scheduling information to a first-served UE to aid in suppression of serving cell signals for second-served UEs.
Claims30
A method of wireless communication of a first-served user equipment (UE) served by a serving cell, comprising:
- detecting an indication conveyed to the UE from the serving cell, the indication indicating that a control channel comprises scheduling information for at least one second-served UE served by the serving cell;
- decoding the control channel and obtaining the scheduling information for the at least one second-served UE from the control channel when the indication is detected;
- receiving a signal, the received signal comprising a first signal intended for the first served UE and a second signal intended for the at least one second-served UE;
- and
- suppressing interference by the second signal from the serving cell based on the obtained scheduling information for the at least one second-served UE.
An apparatus for wireless communication of a first-served user equipment (UE) served by a serving cell, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- detect an indication conveyed to the UE from the serving cell, the indication indicating that a control channel comprises scheduling information for at least one second-served UE served by the serving cell;
- decode the control channel and obtaining the scheduling information for the at least one second-served UE from the control channel when the indication is detected;
- receive a signal, the received signal comprising a first signal intended for the first served UE and a second signal intended for the at least one second-served UE;
- and
- suppress interference by the second signal from the serving cell based on the obtained scheduling information for the at least one second-served UE.
An apparatus for wireless communication of a first-served user equipment (UE) served by a serving cell, comprising:
- means for detecting an indication conveyed to the UE from the serving cell, the indication indicating that a control channel comprises scheduling information for at least one second-served UE served by the serving cell;
- means for decoding the control channel and obtaining the scheduling information for the at least one second-served UE from the control channel when the indication is detected;
- means for receiving a signal, the received signal comprising a first signal intended for the first served UE and a second signal intended for the at least one second-served UE;
- and
- means for suppressing interference by the second signal from the serving cell based on the obtained scheduling information for the at least one second-served UE.
A computer-readable medium storing computer executable code for wireless communication of a first-served user equipment (UE) served by a serving cell, comprising code to:
- detect an indication conveyed to the UE from the serving cell, the indication indicating that a control channel comprises scheduling information for at least one second-served UE served by the serving cell;
- decode the control channel and obtaining the scheduling information for the at least one second-served UE from the control channel when the indication is detected;
- receive a signal, the received signal comprising a first signal intended for the first served UE and a second signal intended for the at least one second-served UE;
- and
- suppress interference by the second signal from the serving cell based on the obtained scheduling information for the at least one second-served UE.
