摘要： A first N×M codebook of a first rank M may be used to generate a second N×(N−M) codebook of a second rank (N−M). This second codebook is both orthogonal and complementary to the first codebook. In practice, this may reduce storage requirements in closed-loop MIMO beamforming, because the second codebook may be dynamically generated as needed by a base station and/or a mobile station. In some cases, a higher rank beamforming matrix or precoding matrix may be formed from a lower rank (e.g., one or two) beamforming matrix or precoding matrix. Also, a novel way to generate the rotation matrix Qv(t−1) is disclosed.
摘要翻译：可以使用第一等级M的第一N×M码本来生成第二等级（N-M）的第二N×（N-M）个码本。该第二码本与第一码本正交和互补。实际上，这可能减少闭环MIMO波束成形中的存储要求，因为第二码本可以根据基站和/或移动台的需要动态生成。在一些情况下，可以从较低等级（例如，一个或两个）波束形成矩阵或预编码矩阵形成较高秩波束形成矩阵或预编码矩阵。另外，公开了生成旋转矩阵Qv（t-1）的新颖方式。

摘要： Embodiments of an eNB and method of transmitting PDCCHs are generally described herein. In some embodiments, the eNB may be configured to transmit PDCCHs that are based on a UE-specific reference signal (i.e., a UE-RS). In these embodiments, the UEs may be able to demodulate their PDCCH using a demodulation reference signal (DM-RS) that is specific to the UE (e.g., instead of a common reference signal). The PDCCHs disclosed herein may be suitable the Uu interface of an LTE-A system.

One method comprises mapping modulated symbols in the ePDCCH to at least one control channel element. The at least one control channel element can be mapped to resource elements located in a plurality of distributed physical resource blocks in a subframe, wherein each resource block is separated by at least one additional resource block in the subframe. The mapping can also be to resource elements distributed in a single resource block in the subframe, wherein the control channel element is mapped to be distributed in frequency and time relative to other mapped resource elements in the single resource block.

摘要： Embodiments of the disclosure provide auto-detection in wireless telecommunications. Certain embodiments provide or otherwise implement a specific sequence of bits and/or symbols for auto-detection. The specific sequence of bits can be embodied in or can include output codebits from an encoder in a communication device that can send a wireless transmission including the specific sequence. In one embodiment, the encoder can compute or otherwise generate cyclic redundancy checks (CRCs) or other types of validation checks at the communication device. The specific sequence can be determined using the payload of a packet frame. Both the manner in which the specific sequence is generated and the temporal order in which the specific sequence is received relative to other payload in the packet frame can provide specificity to the sequence.

摘要： Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11 ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.

摘要： A user equipment (UE) includes a request receipt component, an interference component, and a grant/deny component. The request receipt component is configured to receive a first signal indicating a request to transmit to the UE from a first transmitting UE and to receive one or more additional signals indicating that one or more additional transmitting UEs are requesting to transmit to corresponding target UEs. The interference component identifies, based on a received power of the first signal and the one or more additional signals, one or more potentially incompatible UEs. The incompatible UEs may include at least one of the one or more additional transmitting UEs. The grant/deny component is configured to send a signal indicating a block on transmission by the one or more incompatible UEs.
