Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for license assisted access (LAA) communications on an unlicensed channel. The eNB determines if a subframe to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain both a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) at fixed symbol positions within the subframe. In further embodiments, the eNB determines if a last subframe of a downlink (DL) transmission burst to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain a discovery reference signal (DRS) for transmission.

Abstract: Example systems, methods, and devices for extending range of WiFi networks are discussed. More specifically, methods for extending range of a Wi-Fi network are disclosed. The method may include the operations of appending, by a network device, one or more codebits to one or more original codebits or coded symbols, sending, by the network device, the original codebits or coded symbols and the appended codebits to an interleaver or a constellation mapper for transmission. The original codebits or coded symbols and the appended codebits may be sent over a plurality of subcarriers. Methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.

Abstract: A user equipment (UE) is configured to receive a maximum probability of accessing a wireless local area network (WLAN) for communication. The maximum probability is received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE is further configured to determine that there is a queued transmission for the UE and, in response to determining that there is a queued transmission, to determine whether the UE is authorized to access to the WLAN using a probability less than or equal to the maximum probability. The UE is further configured to delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized.

Abstract: A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.
