Abstract: According UE is configured to receive a channel state information reference signal (CSI-RS) from an evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB), determine channel state information based on the CSI-RS, and send the channel state information to the eNB. The channel state information includes a precoding matrix indicator corresponding to a first precoding matrix. The UE is also configured to receive a UE specific reference (UE-RS) signal and a physical downlink shared channel (PDSCH) signal. The UE-RS is precoded with a second precoding matrix. The UE estimates a UE-RS effective channel including the second precoding matrix based on the UE-RS and decodes data from the PDSCH signal based on an the first precoding matrix and the UE-RS effective channel.

Abstract: Embodiments allow an eNBs and a target UE to both calculate which resource block groups (RBGs) to use to transmit data. Because the RBGs that will contain information of interest can be pre-calculated, there is no need to receive and store all RBGs in the transmitted signal before decoding the signal and identifying which RBGs are of interest to the recipient. This allows receivers to buffer and/or store only those RBGs that will contain received information and discard others. The amount of information that needs to be stored and/or buffered thus is less and can result in receivers with less memory and, hence, lower cost. In order to calculate which RBGs are to be used to transmit and/or receive information, a logical RBG index is first calculated and the logical RBG index is mapped to a physical RBG index.

Abstract: Techniques are described for compressing the PUCCH resources reserved for acknowledging downlink data transmissions when those resources are implicitly signaled by EPDCCHs that schedule the downlink transmissions in TDD mode. An acknowledgment resource offset field transmitted in the EPDCCH is configured to correspond to one or more values that compress the region in PUCCH resource index space that would otherwise be reserved for the subframes of a bundling window.

Abstract: Methods, apparatuses, and computer-readable media for a wireless communication device for transmitting pilots in a wireless local area network are disclosed. The method on a wireless communication device includes receiving one or more packets in a transmit opportunity (TXOP), wherein the one or more packets indicate a schedule for the wireless communications device to transmit. The method further includes transmitting a first pilot carrier in a lower subcarrier of a frequency allocation, and transmitting a second pilot carrier in a higher subcarrier of the frequency allocation. The first pilot and the second pilot may be transmitted simultaneously or in alternative time periods. The lower subcarrier may be the lower one-third of the frequency allocation, and the higher subcarrier may be the higher one-third of the frequency allocation. The wireless communication device may transmit and receive in accordance with OFDMA and 802.11.

Abstract: Embodiments for long training field (LTF) sequences or other types of sequences in uplink multi-user multiple-input multiple-output communications are provided. The LTF sequences can permit channel estimation, including determination of carrier frequency offsets. In some embodiments, an LTF sequence can be formatted and/or conveyed without reliance on pilot tones. In other embodiments, the LTF sequence can rely on pilot tones, where a sequence associated with the pilot tones can include elements that are orthogonal among transmitter station devices that communicate according to MU-MIMO.
