摘要： A system and method for facilitating resource management in OFDM systems is provided. The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT, RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The facilitation system also comprises a variety of transmitting protocols, command increment variable stepsize methods and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

摘要： Systems and methodologies are described that facilitate responding to overload indicators in a wireless communication environment. A non-serving base station can send an over-the-air (OTA) overload indicator (OI) and a backhaul OI. A UE can receive the OTA OI from the non-serving base station, generate a report based upon the OTA OI, and send the report to a serving base station. The serving base station can receive the report from the UE, and generate a power control command for the UE based at least in part upon the report. Moreover, the serving base station can generate the power control command for the UE further based upon the backhaul OI received from the non-serving base station. For example, the UE can be configured to ignore the OTA OI. By way of another example, the serving base station can cause the non-serving base station to inhibit sending the backhaul OI.

摘要： Techniques for transmitting data using a combination of explicit cyclic delay and implicit cyclic delay are described. A transmitter may perform first processing for cyclic delay diversity (or explicit cyclic delay processing) based on a first set of cyclic delay values known to a receiver. The transmitter may perform precoding based on a precoding matrix either before or after the explicit cyclic delay processing. The transmitter may perform second processing for cyclic delay diversity (or implicit cyclic delay processing) based on a second set of cyclic delay values unknown to the receiver. The transmitter may perform both explicit and implicit cyclic delay processing for data and may perform only implicit cyclic delay processing for pilot. One entity may select the first set of cyclic delay values and inform the other entity. The transmitter may autonomously select the second set of cyclic delay values without informing the receiver.

摘要： Devices and methods are provided for implementing an over-the-air (OTA) broadcast of an overload indication to reduce interference levels at neighboring node(s). In one embodiment, the method involves receiving the OTA broadcast of the overload indication from a neighboring node. The method further involves performing transmit power control based upon the received overload indication to reduce Interference over Thermal (IoT) noise at the neighboring node (e.g., by adjusting the transmit power spectral density). Such a method may be performed, for example, by an access terminal or a small base node.

摘要： Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type. The method may involve allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of second set having a second CP type. The method may involve determining whether the first CP type and the second CP type are the same. The method may involve, in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.
