Abstract:
Devices, systems and methods are described for mitigating interference in a wireless communications network. In particular, the network may be a Wi-Fi network. Multiple approaches may be implemented to mitigate ACI. Further, multiple approaches may be implemented to mitigate non-Wi-Fi interference as well. Each of the approaches may consist of two parts, namely, interference detection and interference mitigation (or reduction). One approach may involve: detecting adjacent channel interference (ACI) in an operating channel of the device; determining a location of the detected ACI in an operating band of the device; and mitigating the detected ACI by communicating via a channel different from the operating channel, the different channel being determined to be further away from the location of the detected ACI.
Abstract:
Methods and apparatus are disclosed for interference mitigation of an open-access node. The method includes determining, at the open-access node, whether uplink interference from a mobile entity is above a threshold. The method includes adjusting a transmission power to trigger a hand-in of the mobile entity in response to determining the uplink interference is above the threshold. The method includes handing-in the mobile entity from a first cell in response to adjusting the transmission power. The method includes redirecting the mobile entity to a second cell different from the first cell.
Abstract:
Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.
Abstract:
Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.
Abstract:
The present disclosure presents methods and apparatuses for improved wireless node transmission of advertising beacons based on, for example, the presence of sufficient wireless node resource availability and one or more user equipment (UE) wakeup schedules. For example, the present disclosure describes example methods of advertising beacon transmission by a wireless node, which may include determining that a resource availability opportunity exists for supporting a UE at the wireless node. In another aspect, methods may include tuning to a non-serving channel based on determining that the resource availability opportunity exists. According to such example methods, the non-serving channel may be different from a serving channel of the wireless node. Furthermore, the example methods may include transmitting an advertising beacon on the non-serving channel. Upon successful receipt of the advertising beacon, the UE may scan for the serving channel of the wireless node for subsequent wireless network access.
Abstract:
Systems, methods, and devices for concurrently allowing station-to-station transmissions and access point-to-station transmissions are described herein. In some aspects, a method comprises receiving, from a first device, a peer request to send message requesting a first time for transmissions with a second device. The method further comprises reserving the first time for transmissions between the first device and the second device. The method further comprises transmitting a coordination message to the first device and the second device. The coordination message may indicate that the first time is reserved for transmissions between the first device and the second device. The method further comprises transmitting a first data packet to a third device during a time other than the first time. The first device may transmit a second data packet to the second device during the first time.
Abstract:
An apparatus and method for managing interference in a transmission medium are disclosed. A apparatus and method may be used to detect a condition experienced by only one of first and second wireless nodes, and modify an operational parameter of one of the first and second wireless nodes, if the condition is detected, such that both the first and second wireless nodes experience the condition or neither the first and second wireless nodes experience the condition.
Abstract:
Systems and methods are provided for reporting high mobility user equipment (UE) in a wireless network. This may be achieved, for example, by detecting a high mobility UE at a network node and reporting the high mobility UE in a blocking message to one or more other network nodes.
Abstract:
Methods, systems, and devices for wireless communications are described. A wireless communications system may support techniques for random access response (RAR) enhancements for multiple random access channel (RACH) procedures. In some cases, a user equipment (UE) may receive multiple physical downlink control channel (PDCCH) orders triggering respective RACH procedures, each PDCCH order indicating a preamble identifier associated with the respective RACH procedure. In some cases, the preamble identifiers may be the same or different. The UE may transmit a random access preamble corresponding to a preamble identifier indicated in a PDCCH order and may receive a random access response associated with a respective RACH procedure based at least in part on an indication included in the random access response. In some cases, the indication may be associated with a preamble identifier indication. In some other cases, the indication may be associated with a timing advance group.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message that includes a frequency domain resource allocation (FDRA). The FDRA may indicate a set of resource blocks (RBs), and the UE uses the indicated set of RBs to identify a first set of RBs for uplink communications using a first transmission configuration indicator (TCI) state and a second set of RBs for uplink communications using a second TCI state, both of which satisfy a threshold for performing transform precoding. The UE may transform precoding the first uplink signaling and the second uplink signaling based on the first and second sets of RBs satisfying the threshold for performing transform precoding.
