摘要： Techniques for supporting data transmission with single-user multiple-input multiple-output (SU-MIMO) and multi-user MIMO (MU-MIMO) are described. A base station may transmit multiple data streams on a given time-frequency resource to a single user equipment (UE) for SU-MIMO or to multiple UEs for MU-MIMO. In an aspect, an antenna port assignment for a UE for MU-MIMO may be conveyed by reusing one or more fields of a downlink control information (DCI) format. In another aspect, a hierarchical two-tier structure may be used to convey an antenna port assignment for a UE for MU-MIMO. In yet another aspect, a UE may be configured via higher layer to report only channel quality indicator (CQI), or both CQI and precoding matrix indicator (PMI), when operating in a transmission mode supporting SU-MIMO and MU-MIMO. In yet another aspect, a UE may report CQI such that SU-MIMO and MU-MIMO can be supported for the UE.

摘要： Systems and methodologies are described that facilitate configuring a sounding reference signal transmission in a wireless communication environment. A UE can employ coordinated multi-point transmission and/or reception such that multiple cells collaborate to transmit data to the UE and/or receive data from the UE. To support the coordinated multi-point transmission and/or reception, the UE can transmit a sounding reference signal that is configured to enable reliable reception of the sounding reference signal by members of a cooperating set. In addition, configuration of the sounding reference signal can be coordinated to enable more efficient transmission and utilization of the sounding reference signal. Configuration of the sounding reference signal can be based upon information exchanged between the multiple cells. Moreover, the multiple cells can coordinate to set and control a transmit power of the sounding reference signal.

摘要： Systems and methodologies are described that facilitate sending and/or receiving user equipment specific reference signals (UE-RSs) in a wireless communication environment. A UE-RS pattern can be selected, yielded, etc. based upon a number of symbols from a subframe utilized for downlink transmission. At least one time domain component of the UE-RS pattern can vary based upon the number of symbols from the subframe utilized for the downlink transmission. For instance, the at least one time domain component can be punctured, time-shifted, and so forth. Further, UE-RSs can be mapped to resource elements of the subframe as a function of the UE-RS pattern. Moreover, a UE can utilize the UE-RS pattern to detect UE-RSs on the resource elements of the subframe. Further, the UE can estimate a channel based upon the UE- RSs.

摘要： Systems and methodologies are described herein that facilitate improved modulation and coding techniques for a multiple-in multiple-out (MIMO) communication system. As described herein, data to be transmitted over a set of physical layers (e.g., corresponding to antennas, beams, etc.) can be processed such that encoding is performed on a per-codeword basis and modulation is performed on a per- layer basis, thereby mitigating performance degradation experienced by traditional systems due to layer imbalance. As further described herein, per-codeword code rate parameters and per-layer modulation parameters can be signaled to a device in various manners, such as through modulation and coding scheme (MCS) signaling, explicit code rate and/or modulation scheme signaling, relative code rate and/or modulation scheme signaling, or the like.

摘要： Systems and methodologies are described that facilitate assigning uplink resources for utilization by a mobile device for sending an uplink signal in an uplink coordinated multi-point (CoMP) wireless communication environment. For instance, a hopping tree can be defined across base stations, and neighboring base stations can schedule interfering mobile devices upon uplink resources mapped to different nodes from the hopping tree. By way of another example, a plurality of hopping trees can be employed across base stations in the uplink CoMP wireless communication environment. Moreover, an acknowledgment can be sent to the mobile device upon downlink resources identified as a function of the uplink resources. Further, the downlink resources can be distinct from disparate downlink resources utilized for sending an acknowledgment to a disparate mobile device from a neighboring base station.

摘要： Aspects are disclosed for multiplexing disparate wireless terminals. Resource blocks (640) are mapped according to a hopping pattern. A first and second pair of physical resource blocks are allocated such that the first pair is associated with a first hopping index pair, whereas the second pair is associated with a second hopping index pair. For this embodiment, the first and second hopping index pairs are inversely symmetrical to each other. A pair of distributed resource blocks is also allocated. An assignment is then scheduled that includes a physical resource allocation and a virtual resource allocation. Aspects for operating a wireless terminal are also disclosed. Here, a communication that includes a resource allocation and a reference signal is received. A minimum resource allocation granularity is ascertained from the communication, and a joint channel estimation is based on the reference signal and is a function of the minimum resource allocation granularity.
