Abstract: A first wireless device of a wireless local network is operated in an un-associated data transfer mode at a layer-2 level. In the un-associated data transfer mode, communication between the first wireless device and a second wireless device in the wireless local network is allowed to take place without prior authentication and association between the two wireless devices. The first wireless device participates in formulation of routing information in routing nodes of a wireless mesh network while operating in the un-associated data transfer mode. If configured as an end device, the first wireless device thereafter exchanges data packets with another wireless device in the mesh. If configured as a router, the first wireless device routes packets to corresponding wireless devices in the mesh. Operation in the un-associated data transfer mode may result in reduction in power consumption of nodes in the mesh, as well as increased data throughput.

The wireless terminal is also capable of transmitting a representation of at least a portion of the precoding matrix to the base station.

Abstract: In wireless operating environments, wireless user devices are often within the coverage area of multiple base stations. The base station providing the best uplink for the user device may be different than the base station providing the best downlink for the user device. Systems and techniques for asymmetric uplink and downlink communications for a user device are provided. In embodiments, the user device initially synchronizes with a base station. Both the uplink and downlink are initially served by this base station. A determination is then made whether to handoff the downlink for the user device to another base station. When a determination is indicated, the downlink is handed off to the second base station. Thereafter, periodic measurements are made. The determinations whether to handoff the uplink and downlink for the user device are made independently.

In particular, the disclosure is directed to selecting a path between two nodes in a wireless mesh network based on consideration of type of data requested and a determination whether an intermediate node, within a predetermined range of the requesting node, is actively broadcasting the requested data. Such opportunistic consideration in selecting a path between two nodes may avoid unnecessary activation of additional broadcasting nodes and reduce the risk of triggering interference between multiple nodes broadcasting duplicate data.

Abstract: A single hybrid automatic repeat request (HARQ) entity can be associated with multiple serving units to achieve lower complexity user-side signal processing during multi-point communication. Additionally, configuring a single HARQ entity to establish HARQ operations with multiple serving units may achieve lower latency communication when users are engaging in multi-point communications, such as coordinated multi-point transmission/reception (CoMP). HARQ entity associations and/or reconfigurations can be achieved through radio resource control (RRC) signaling.
