Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a measurement scheme or uplink mode and then transmit an indication of the scheme or uplink mode to an associated user equipment (UE). The base station may identify a set of hidden nodes for the UE and configure the UE for autonomous or grant-based uplink transmissions accordingly. A UE may initiate a channel clearance scheme by transmitting a first channel clearance signal (e.g., a request-to-send message), which may include a UE identifier before transmitting an uplink message in the unlicensed radio frequency spectrum band. In response, the base station may transmit a second channel clearance signal (e.g., a clear-to-send message). In some cases, the second channel clearance signal may include control information or may be transmitted at a power level that is based on a characteristic of the UE.

Abstract: The present invention is designed so that UL signals of a plurality of user terminals can be multiplexed and communicated in cells where listening is employed (for example, unlicensed bands). According to the present invention, a user terminal communicates with a radio base station in a cell where listening is executed before uplink (UL) signals are transmitted, and has a transmission section that transmits UL signals, and a control section that controls the transmission of UL signals based on the result of listening. The control section makes the listening period for executing listening and the transmission period for transmitting UL signals the same among a plurality of user terminals that are scheduled in the same subframe.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may identify a contention window for a no-energy-detection protocol for determining a channel availability for a data transmission. After the contention window expires, the transmitter may send a request message to a receiver. The receiver may measure a quality of the request message against a request threshold and transmit a response message if the measured quality exceeds the request threshold. The transmitter may then measure a quality of the response message against a response threshold. If the measured quality exceeds the response threshold, the transmitter may initiate a data transmission with the receiver. If the quality falls below the response threshold or the response message is not received, the transmitter may adjust the contention window and reattempt the no-energy-detection protocol. The contention window may also be adjusted based on an acknowledgement message received after the data transmission.

Abstract: A system and method for detecting and receiving packets that are transmitted over a network that utilizes a plurality of channels is disclosed. The system includes a radio circuit, which can be configured to receive packets over a plurality of channels, a processing unit, and a memory in communication with the processing unit. The processing unit loads a set of operating parameters in the radio circuit, which enables the radio circuit to detect and receive packets on a particular channel. If a preamble is not detected within a predetermined time period, the system hops to a different channel by loading a second set of operating parameters in the radio circuit. This process can be repeated for an arbitrary number of channels.

Abstract: Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.

Abstract: A network node (110), a wireless device (120) and methods therein, for enabling the wireless device (120) to obtain configuration information from a multicast control channel, e.g. SC-MCCH, which is transmitted by the network node (110). The network node (110) transmits an indication of change of the multicast control channel, wherein the indication further indicates whether the wireless device (120) is affected by the change and needs to acquire or obtain the multicast control channel or not. The network node (110) further transmits the multicast control channel as changed according to said indication. Thereby, the wireless device (120) can decide to obtain and acquire the multicast control channel only if it is affected by the change and to refrain when not affected, which will reduce the consumption of energy in the wireless device (120).

First, a packet error characteristic data of a channel for a Downlink (DL) Multi-user (MU) group may be received. Next, the received packet error characteristic data may be provided as input data to a classifier model. Then, in response to providing the received packet error characteristic data as the input data to the classifier model, output data may be received from the classifier model. The output data may indicate at least one probability value corresponding to at least one channel effect. An optimization for improving performance of DL MU-MIMO in the presence of the at least one channel effect may then be performed when the at least one probability value is above or below a predetermined level.

Abstract: Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.

Abstract: Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may use quasi co-located antenna ports for transmission and reception of synchronization and/or reference signals and positioning reference signals. For example, the base station may identify a quasi co-location relationship indicating that antenna ports of the base station used to transmit a synchronization signal are quasi co-located with antenna ports of the base station used to transmit a positioning reference signal. In some cases, the base station may transmit an indication of the quasi co-location relationship to the UE. Additionally, the UE may receive the synchronization signal and determine a receive beam for the UE to use to receive the positioning reference signal based at least in part on the received synchronization signal and the identified quasi co-location relationship. The UE may then receive a positioning reference signal using the determined receive beam.

Abstract: The present invention relates to methods and arrangements that make it possible to control the delay for the UEs to access the EUL resources in the Enhanced Uplink in CELL_FACH state procedure, independently from the delay for the UEs to access ordinary UL resources in the RACH procedure. This is achieved by a solution where the timing of entering (or re-entering) a transmission procedure for Enhanced Uplink in CELL_FACH state is controlled with the help of a transmission control parameter defined specifically for this transmission procedure, instead of using the same parameter as for the RACH procedure.
