摘要： Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.

摘要： Systems and methodologies are described that facilitate employing flexible signaling of resource block assignments on a control channel. Resource blocks associated with an uplink or downlink channel can be split into a plurality of groups, and group-specific signaling constraints can be utilized with each of these groups. For example, the group-specific signaling constraints can relate to minimum resource block allocation units, signaling structures (e.g., bitmap structure, contiguous allocation structure, tree-based structure, . . . ), and the like utilized for sending assignment indications that allocate resource blocks within the respective groups. Further, an access terminal can have a common understanding of the group-specific signaling constraints; thus, a received assignment indication can be deciphered by the access terminal by utilizing the group-specific signaling constraints.

摘要： A system and method for facilitating resource management in OFDM systems is provided. The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT, RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The facilitation system also comprises a variety of transmitting protocols, command increment variable stepsize methods and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

摘要： Methods and apparatuses are provided for determining cyclic shift (CS) values and/or orthogonal cover codes (OCC) for a plurality of demodulation reference signals (DM-RS) transmitted over multiple layers in multiple-input multiple-output (MIMO) communications. A CS index can be received from a base station in downlink control information (DCI) or similar signaling. Based at least in part on the CS index, CS values for the plurality of DM-RSs can be determined. In addition, OCC can be explicitly signaled or similarly determined from the CS index and/or a configured CS value received from a higher layer. In addition, controlling assignment of CS indices and/or OCC can facilitate providing orthogonality for communications from paired devices in multiuser MIMO.

摘要： Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.

摘要： Techniques for assigning acknowledgement (ACK) resource to a user equipment (UE) in a wireless communication system are described. In one design, a first parameter indicative of radio resources (e.g., the lowest index of at least one physical resource block) allocated to the UE for data transmission may be obtained. A second parameter indicative of another resource (e.g., a cyclic shift of a reference signal sequence) assigned to the UE for data transmission may also be obtained. The first and/or second parameter may be restricted, and each restricted parameter may be limited to a set of allowed values among all available values for the parameter. ACK resource assigned to the UE for data transmission may be determined based on the first and second parameters. In one design, sequential first parameter values may be mapped to sequential ACK resources indices. In another design, mirror mapping with different mapping directions may be used for different allowed values of the second parameter.
