    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 License Assisted Access (LAA) enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween operating in a Long Term Evolution unlicensed band (LTE-U) are generally described. The eNB may transmit a request to the UE for information regarding a Wireless Local Area Network (WLAN) over which the UE may be able to communicate. The WLAN information may include an LTE-U channel and time window for reporting. The UE may obtain the WLAN information through communication with an access point (AP). Measurement information of the LTE-U channel may also be obtained by or on behalf of the UE. The UE may transmit the WLAN information to the eNB. The eNB may use the WLAN information or submit the WLAN information to a network entity to perform channel selection, UE grouping or localization, appointing delegate UEs to perform channel sensing or scheduling UEs in a same group or proximity.

    摘要: Described are methods and devices for enabling D2D communications with signal structures that require minimal changes to the current LTE architecture. In the embodiments described, the eNB grants resources to UEs for D2D communication and either initiates or permits a pair of UEs to establish a D2D link. Certain embodiments are designed to minimize changes to the current LTE control signaling structure by having the control signaling always come from the eNB as in a normal cellular link so that the transmitting UE transmits over a data channel (e.g., PUSCH/PDSCH) that the receiving UE is able to decode.

    摘要: In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ration transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.

    摘要: A STA, AP and method of reducing channel allocation control overhead are disclosed. The STA receives a high-efficiency Physical Layer Convergence Protocol Data Unit (HE PPDU) having a HE SIG-A field followed by a HE SIG-B field. The SIG-B field has user-specific subfields (USS), each having a stream allocation value (SAV) for an associated STA and associated with a unique stream index number (SIN) indicating a position among the USSs. The SINs increase with increasing position from the SIG-B field. The number of channels allocated in each USS is constrained to stay the same or monotonically change with increasing SIN. The STA determines channel allocation from the SAV, SIN and number of USSs. The channels may be allocated non-contiguously. The SAVs in most USSs may indicate an allocation to increasing or decreasing channels and in the final USS to at least one channel starting from a final or initial channel.
