Abstract: Aspects provide a way for RS in different sub-bands within the same OFDM symbol to have different RS placement designs, e.g., different dependence/independence on cell ID. A base station apparatus transmits a first RS in a first resource set using a first RS placement, wherein the first resource set comprises a first subband of an OFDM symbol. The apparatus also transmits a second RS in a second resource set using a second RS placement, wherein the second resource set comprises a second subband of the OFDM symbol. A UE apparatus identifies a first resource set comprising a first subband in a plurality of subbands of an OFDM symbol transmitted by base station, determines whether a RS tone location utilized with the first subband is dependent upon an identifier of the base station, and receives the RS based on a result of the determining.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus reduces inference in a received signal. The apparatus receives a signal including transmissions from a plurality of cells. The apparatus determines transmission parameter hypotheses associated with the plurality of cells. Each transmission parameter hypothesis from the transmission parameter hypotheses includes a set of transmission parameters associated with all the cells from the plurality cells. The apparatus selects at least one transmission parameter hypothesis based on a first metric applied to each hypothesis. The apparatus refines transmission parameters associated with at least one cell from the plurality of cells. The refining includes improving an accuracy of the transmission parameters associated with the at least one cell based on a second metric associated with each cell individually.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may perform one or more process that enable smart processing of resource elements from interfering base stations in order to improve cell decoding. The method includes prioritizing resource elements in order to reduce complexity of processing of the interfering resource elements. Some resource elements may be excluded from processing if priority is set to a null value or to a sufficiently low value. Resource elements in a subframe received from an interfering transmitter are grouped into one or more target regions and paired with serving and interfering cells. Each pairing is prioritized and processed in an order based on the priorities assigned to the pairings.

Abstract: In an embodiment, a UE determines QCL information that indicates an association between a spatial parameter and a current transmission configuration, and conveys the determined QCL information to a BS. In another embodiment, a BS transmits a DCI that triggers transmission of a reference signal that includes QCL information that indicates an association between a spatial parameter and a current transmission configuration, whereby any DCI triggering any reference signal that includes any QCL information is configured to trigger a UE to send an express acknowledgment or an implied acknowledgment to that DCI.
