    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: A PDSCH resource element mapping method is used for joint transmissions. The method solves a problem of colliding resource elements in joint transmissions, due to interference caused when PDSCH resource elements are transmitted in the resource block of one cell and cell-specific reference signals (CRSs) are transmitted in the same location of the resource block of an adjacent cell. The method is particularly beneficial for coordinated multipoint (CoMP) transmissions. The PDSCH resource element mapping method employs one of three schemes for transmitting the collided resource elements, with minimal interference. In the first scheme, one PDSCH symbol is transmitted over three consecutive CRS-collided PDSCH resource elements. In the second scheme, two PDSCH symbols are transmitted over three consecutive CRS-collided PDSCH resource elements. In a third scheme, CRS-collided resource elements are transmitted using a lower modulation order than is specified by the modulation and coding scheme.

    摘要: Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.

    摘要: Embodiments of User Equipment (UE), an Evolved Node-B (eNB), and methods for channel quality indicator (CQI) feedback are disclosed herein. An aperiodic CQI type parameter received at the UE may indicate a CQI type for use in a determination of an aperiodic CQI based on signals received from the eNB. Channel-state information reference signals (CSI-RS) may be used when single-user multiple-input multiple-output (SU-MIMO) signals are received. Physical downlink shared channel (PDSCH) blocks may be used when multi-user multiple-input multiple-output (MU-MIMO) signals are received. The aperiodic CQI may be transmitted to the eNB as part of an aperiodic CQI measurement report. In addition, periodic CQI measurement reports may also be transmitted to the eNB and may include periodic CQIs that are based on CSI-RS received at the UE.

    摘要: Apparatuses, methods, and computer readable media for signaling high efficiency short training field are disclosed. A high-efficiency wireless local-area network (HEW) station is disclosed. The HEW station may comprise circuitry configured to: receive a trigger frame comprising an allocation of a resource block for the HEW station, and transmit a high efficiency short training field (HE-STF) with a same bandwidth as a subsequent data portion, wherein the transmit is to be in accordance with orthogonal frequency division multiple access (OFDMA) and wherein the transmit is within the resource block. A subcarrier allocation for the HE-STF may matche a subcarrier allocation for the subsequent data portion. The HE-STF and the subsequent data portion may be transmitted with a same power. A total power of active subcarriers of the HE-STF may be equal to or proportional to a second total of data subcarriers and pilot subcarriers of the subsequent data portion.
