    摘要: Techniques for sending signaling messages in a wireless communication network are described. In an aspect, a signaling message (e.g., a reduce interference request) may be sent by mapping it to at least one specific subcarrier among a set of subcarriers reserved for sending the signaling message. The at least one subcarrier may be selected based on the message value. A signal may be sent on the at least one subcarrier in multiple symbol periods to convey the signaling message. In another aspect, a reduce interference request may be sent based on an orthogonal resource among orthogonal resources available for sending reduce interference requests. In one design, an orthogonal sequence may be selected based on the request and may be spread across a resource segment. In another design, the reduce interference request may be processed to obtain modulation symbols, and each modulation symbol may be spread across multiple subcarriers in one symbol period.

    摘要: Techniques for performing power control of multiple channels sent using multiple radio technologies are described. The transmit power of a reference channel, sent using a first radio technology (e.g., CDMA), is adjusted to achieve a target level of performance (e.g., a target erasure rate) for the reference channel. The transmit power of a data channel, sent using a second radio technology (e.g., OFDMA), is adjusted based on the transmit power of the reference channel. In one power control scheme, a reference power spectral density (PSD) level is determined based on the transmit power of the reference channel. A transmit PSD delta for the data channel is adjusted based on interference estimates. A transmit PSD of the data channel is determined based on the reference PSD level and the transmit PSD delta. The transmit power of the data channel is then set to achieve the transmit PSD for the data channel.

    摘要: Techniques for sending hierarchical feedback of channel state information are described. In one design, a user equipment (UE) determines channel gain information for multiple cells selectable to transmit data to the UE. The UE also determines intra-cell relative phase information for at least one cell among the multiple cells. The UE reports the channel gain information and the intra-cell relative phase information. The channel gain information may include multiple quantized channel vectors for each of the multiple cells. The intra-cell relative phase information may indicate phase errors in the quantized channel vectors for each of the at least one cell. The UE may also determine and report other information. The UE may receive data from one or more cells among the plurality of cells. Each cell may transmit data based on at least one transmit vector determined based on the channel gain information and the intra-cell relative phase information.

    摘要: Systems and methodologies are described that facilitate combining received signals from multiple receive antennas in a wireless communication environment. The received signals from the multiple receive antennas can be weighted utilizing an adaptive combination of maximal ratio combining (MRC) and interference nulling. The combination of MRC and interference nulling can be controlled based upon one or more configurable parameters. For instance, a covariance matrix can be modified to include the one or more configurable parameters, and the modified covariance matrix can be utilized in connection with interference nulling. Further, respective values for the one or more configurable parameters can be selected as a function of at least one input (e.g., measured interference-over-thermal (IoT) value, received loading level indicator, eigenvalue distribution of a covariance matrix, . . . ) related to noise correlation.

    摘要: Aspects are disclosed for multiplexing disparate wireless terminals. Resource blocks 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.

    摘要: Providing for record filtering in distributed dynamic clustering algorithms for coordinated multipoint (CoMP) wireless communication is described herein. By way of example, strategy selection records distributed as part of a belief propagation network are pruned at recipient nodes, thereby reducing processing overhead for dynamic clustering. As a result, cooperative policies can be determined with greater efficiency, and with greater relevance to local clusters of cooperating base stations. In some aspects, record pruning can comprise identifying and discarding redundant or incompatible sets of policy decisions. In at least one aspect, a number of evaluated records can be capped based on relevance, while preserving deployment-wide applicability of the belief propagation network. Accordingly, dynamic distributed CoMP decisions are optimized on a deployment-wide scale that more efficiently converges to maximum utility solutions.
