    Abstract: The embodiments herein relates to a method in a user equipment (305) for enabling a base station (301) to schedule the user equipment (305) in a wireless communication system (300). The wireless communication system (300) is in Multiple Input Multiple Output, MIMO, mode and comprises four transmit antennas. The user equipment (305) is connected to the base station (301) via a radio carrier (302). The user equipment (305) determines Channel State Information, CSI, based on information about a Common Pilot Indicator CHannel, CPICH, which CSI comprises Channel Quality Information, CQI, a Rank Indicator, RI, a Precoding Channel Indicator, PCI, and an Hybrid Automatic Repeat reQuest ACKnowledgement/Not ACKnowledgement, HARQ ACK/NACK. The user equipment (305) transmits the CSI to the base station (301) over a plurality of Transmission Time Intervals, TTIs, enabling the base station (301) to schedule the user equipment (305).

    Abstract: A wireless-transmit-and-receiving unit (WTRU) supports receiving information via a plurality of multiple-input-multiple-output (MIMO) streams by providing a low-rank feedback report to a base station. The WTRU selects a preferred HS-PDSCH transmission rank, from a subset of ranks that the WTRU supports. The subset includes ranks that are lower than the maximum HS-PDSCH transmission rank supported by the WTRU. For example, for a WTRU that supports rank-4 reception, the subset may include rank-1 and rank-2. The WTRU generates the low-rank feedback report based on the preferred rank, and transmits the report to the base station.

    Abstract: An apparatus and method for selecting a beam group and a subset of beams in a communication system are disclosed. The method includes: measuring channel state information (CSI) on a downlink from a base station (920); identifying a selected beam group out of a set of beam groups according to a wideband property of the CSI (930); identifying a selected subset of beams in the selected beam group according to at least one subband (940). Wherein the characteristic of the set of beam groups depends on a transmission rank and the number of beams in the selected subset of beams is equal to the transmission rank. The method further includes: generating encoded feedback information identifying the selected beam group and the selected subset of beams for each subband in a double codebook format (950), transmitting the encoded feedback information to the base station. A computer program product comprising the computer program code which is configured to cause the apparatus to implement above operations is also disclosed.
