    摘要： In a cellular network, symbols are encoded and modulated to produce a modulated signal The modulated signal is mapped to a subcarrier using a spatial mapping matrix. An inverse fast Fourier transform is applied to the mapped signal to produce groups of tones. The groups of tones are transmitting concurrently to multiple receivers using the same channel as orthogonal frequency-division multiplexing access (OFDMA) signals. There is one group of tones for each receiver.

    摘要： A method and system enables and improves performance of hybrid automatic repeat request (HARQ) operations on channels between stations of an orthogonal frequency division multiple access (OFDMA) wireless communication network. There, the number of parallel HARQ channels is increased adaptively, and one connection identifier is used to unambiguously identify a set of MAC protocol data units (MPDUs) communicated over parallel HARQ channels. A sequence number is used to avoid out-of-order MPDU delivery when MPDUs are transmitted over parallel HARQ channels. The MPDUs can be concatenated or encapsulated. The maximum number of the parallel HARQ channels can be increased to 256, and can be negotiated when a station enters or re-enters the network.

    摘要： Wireless communication is improved by simultaneously transmitting signals that are orthogonal to received signals. This technique is referred to as Orthogonal Division Duplexing or ODD. Channel characteristics may be estimated based on an analysis of the received signals. Subsequently, techniques used in the transmitting of signals may be adjusted based on the estimated channel characteristics. By using interleaved pilot sub-carriers, each end of a communications link may take measurements of channel conditions. These measurements may be used to adapt the transmission techniques used in the transmitter to the measured channel conditions. Advantageously, this adaptation can occur without the delay in reporting conditions that is characteristic of traditional adaptive communications systems.

    摘要： The embodiments of the invention provide a method for selecting antennas for date transmission in a wireless communication network including user equipment (UE). The network is assigned a band of frequencies, wherein the band is partitioned into at least one set of subbands of the band according to a sounding reference signal (SRS) bandwidth configuration in a form of a codetree having a plurality levels and each level is associated with a partition coefficient. The UE is configured to transmit frequency-hopped SRS on the set of subbands using subsets of the set of antennas. First, the method determines if a number of subbands in the set of the subbands is odd or even based on the SRS bandwidth configuration, and selects a particular subset of the antennas according to whether the number is odd or even. Then, the SRS is transmitted from the particular subset of the antennas.

    摘要： Multiple routes from a data source node to multiple data destination nodes in a large scale multi-hop mesh network are discovered. Nodes discover multiple routes to two destinations in an initial discovery phase that includes only two network-wide flooding of packets. The method can also work with one destination. The method can be extended to include more destinations with a proportional increase in the communication overhead. After the completion of the discovery phase, nodes can communicate or forward their own or received data by using any of the available routes.
