Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for one or more wireless devices to gain access to a wireless channel of a radio frequency spectrum band. In some aspects, a recurring coordinated medium interval is defined in the time domain and associated with the wireless channel. The coordinated medium interval includes a first time period, which may be referred to as a common reservation window, and a second time period, which may be referred to as a scheduled medium access window. During the first time period, access points (APs) attempting to gain access to the wireless channel may transmit reservation signals to reserve one or more scheduled service periods within the second time period of the same coordinated medium interval. The scheduled service periods reserved by an individual AP may be used for UL/DL communications between that AP and its associated stations (STAs).

Abstract: Techniques are described to adjust transmission rates. For example, in a dual-connectivity system, a first communication node can be in communication with a first network node and a second network node. The first communication node may receive from a first network node a first message that includes a recommended bit rate for an ongoing communication between the first communication node and a second communication node. In some embodiments, the first communication node can, in response to receiving the first message, send an acknowledgment or a non-acknowledgment indicator to the first network node indicating that the first communication node accepts or rejects the recommended bit rate.

Abstract: Systems and methods for facilitating the mitigation of interference in the uplink of a small cell caused by macrocell user equipment in the case where the macrocell cannot identify the interfering macrocell user equipment because the user equipment cannot detect and report the small cell's downlink due to the small cell's uplink/downlink coverage imbalance. In an embodiment, the small cell provides the macrocell with a notification of the interference, the configuration information about its Physical Random Access Channel (PRACH), and a plurality of unique preambles and transmission times for non-contention-based transmissions on the small cell's PRACH. The macrocell orders each of one or a plurality of macrocell user equipment to transmit one of the unique preambles on the small cell's PRACH. The small cell reports to the macrocell the detected preamble transmissions, which allows the macrocell to identify interfering user equipment and perform corrective actions.

Abstract: A wireless communication link between a wireless access point and a mobile communication device supports multiple data flows. Each of the data flows can be configured to convey a different type of data. Based on monitoring events/conditions such as conveyance of communications over each of the multiple data flows, a communication management resource selectively assigns data flow compression settings to each of the multiple data flows. Based on the assigned compression settings, the mobile communication device and/or wireless access point communicate packet delivery data (such as network address information) over the data flows. For example, in accordance with the generated compression settings, packet delivery data for data packets conveyed over a first data flow are compressed, while packet delivery data for data packets conveyed over a second data flow are not compressed.

Abstract: Embodiments of a session processing method and a device relating to a data network are provided. The method includes a data-network network element in the data network receiving a data network access request sent by a session management function (SMF) network element of the data network, where the data network access request includes an identifier of user equipment UE and a session address to be used by the UE.
