    Abstract: A wireless communication device comprises a transceiver to communicate directly with one or more separate wireless devices in accordance with a WiFi communication protocol, and a controller. The controller is configured to initiate transmission of information using the transceiver upon expiration of a first contention window (CW) count value, detect whether the transmission is successful, change the CW count value to a second CW count value when the transmission is unsuccessful, and change the CW count value from the first CW count value to a third CW count value when the transmission is successful, wherein the third CW count value is a maximum value of one of the first CW count value divided by a specified binary number or a specified minimum CW count value.

    Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and an evolved Node Bs (“eNBs”) in a plurality of frequency bands. An eNB may transmit cross-carrier, cross-subframe scheduling information to a UE in a licensed frequency band. In response reception of the scheduling information, the UE may sense a wireless transmission medium to determine if the medium is idle. If the medium is idle, the UE may generate and transmit a request to reserve the medium in the unlicensed frequency band (e.g., a Clear-to-Send message). The eNB may transmit downlink data to the UE in the unlicensed frequency band. Other embodiments may be described and/or claimed.

    Abstract translation: 本文所描述的实施例一般涉及用户设备（“UE”）和多个频带中的演进节点B（“eNB”）之间的通信。 eNB可以向许可频带中的UE发送跨载波跨子帧调度信息。 响应于调度信息的接收，UE可以感测无线传输介质以确定介质是否空闲。 如果介质空闲，则UE可以生成并发送在非许可频带（例如，清除发送消息）中保留介质的请求。 eNB可以在非许可频带中向UE发送下行链路数据。 可以描述和/或要求保护其他实施例。

    Abstract: A user equipment (UE) can include processing circuitry configured to, during a physical random access channel (PRACH) procedure, select a first synchronization signal (SS) block from a plurality of SS blocks within a received SS burst set, the SS block selected based on signal quality measurements of the plurality of SS blocks. A PRACH preamble is encoded for transmission to a base station using a PRACH resource subset corresponding to the selected SS block, the transmission using a UE transmit (Tx) beam of a plurality of available Tx beams and transmit power indicated by a power ramping counter. Upon failing to detect a random access response (RAR) from the base station, a second SS block is selected, the power ramping counter is reset, and the PRACH preamble is encoded for re-transmission using a second PRACH resource subset and transmit power indicated by the reset power ramping counter.

    Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable scheduling UL transmissions on transmission opportunities outside of the UL grants or for multi-carrier UL scheduling. A communication component of the device can operate to process or generate communications on an unlicensed band or a licensed band in response to UL grants and indications provided via a DL transmission for scheduling. An eNB can provide indications to a UE for processing that indicate whether a transmission opportunity is on the same transmission opportunity as the UL grants or an external/outside transmission opportunity. The indications can further trigger an listen-before-talk (LBT) protocol, which can vary between a category 4 LBT or a single LBT interval that is shorter than the category 4 LBT, depending on the indication.

    Abstract: Techniques for communication of a partial subframe and properties related to the partial subframe of a plurality of subframes in licensed assisted access (LAA) for an unlicensed frequency band are discussed. A network device (e.g., an evolved NodeB, or other cell network device) can generate a listen before talk (LBT) protocol in order to determine whether an unlicensed carrier of a secondary cell device is idle or busy. The evolved Node B (eNB) can communicate starting or ending partial subframes in a downlink transmission, and a user equipment (UE) can process partial subframes based on the communications and a scheduling policy.
