摘要： Systems and methods are described that facilitate assigning a predefined manner in which interfering transmissions may be fully or partially orthogonalized, as well as transmission time periods during which the orthogonalization protocol(s) may be employed. Depending on interference conditions, flexible resource reuse may be implemented to mitigate interference without unduly taxing resources. The subject of the innovation may be employed in, for instance, an ad hoc or unplanned/semi-planned wireless communication environment.

摘要： Methods and apparatus related to partitioning traffic segments are described. An access router, having concurrent connections with two access terminals, each desiring to transmit traffic signals to the access router in the same traffic segment, partitions a traffic segment. The partition is such that a first portion of the traffic segment is allocated to a first access terminal and a second portion of the traffic segment is allocated to the second access terminal. Control information, e.g., conveying partition information, is communicated to access terminals prior to the traffic segment. In some embodiments, the partition information is communicated as part of a transmission request response signal, e.g., via phase of the request response signal. An access terminal which has been allocated a traffic segment partition portion identifies is allocation from the transmitted control information, and subsequently transmits traffic signals to the access router in its allocated portion of the traffic segment.

摘要： Systems and methodologies are described that facilitate transmitting positioning reference signals (PRS) differently for passive distributed elements. PRSs for passive distributed elements can be transmitted over disparate resources than those utilized for PRSs at a related access point, using different symbol sequences, and/or the like. In this regard, wireless devices can differentiate between PRSs from access points and those from passive distributed elements, which can mitigate confusion for processes involving such RSs, such as position determining. Alternatively, passive distributed elements can refrain from transmitting PRSs, and a corresponding access point can indicate to wireless devices to only determine positioning based on PRSs. Thus, the wireless devices can utilize the PRSs transmitted from the access point (and not other reference signals transmitted from the passive distributed element) to determine a position.

摘要： Certain aspects of the present disclosure provide a technique for bundling the received service data units (SDU) in a first communication layer to generate a protocol data unit (PDU) to pass to a second communication layer. For example, one or more packet data convergence protocol (PDCP) SDUs may be concatenated to generate a PDCP PDU and be sent to a radio link control (RLC) layer in the transmitter side. Similarly, one or more PDCP SDUs may be extracted from a PDCP PDU in the receiver side.

摘要： A method of managing contention in a wireless network is described. The wireless network may include an access router and a plurality of access terminals connectable to the base station. The method may include designating a data slot as a downlink slot or an uplink slot, and sending a signal from the access router to the access terminals to indicate the designation of the data slot. The access router may determine whether the data slot should be designated as a downlink slot or an uplink slot by assessing information such QoS (quality of service) requirements contained in a REQ message received from one or more of the access terminals, and information regarding buffer level received from one or more of the access terminals.
