Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

Abstract: An eNode-B for a multi-user multiple-input multiple-output (MU-MIMO) downlink transmission to at least first and second wireless transmit/receive units (WTRUs) via resource elements (REs) of first and second spatial layers, the eNode-B comprising a transmitter and a processor, the processor coupled to the transmitter. The processor configured to generate the MU-MIMO downlink transmission including: allocating a first set of the REs, as first resources, to the first spatial layer for the first WTRU, and a second set of the REs, as second resources, to the second spatial layer for the second WTRU, mapping a first WTRU-specific reference signal (RS) associated with the first WTRU on a subset of the first resources, and a second WTRU-specific RS associated with the second WTRU on a subset of the second resources, muting allocated REs of the first resources overlapping with the subset of the second resources used for the second WTRU-specific RS, and allocated REs of the second resources overlapping with the subset of the first resources used for the first WTRU-specific RS. The transmitter configured to send the MU-MIMO downlink transmission.
