Abstract: Systems and methods are described that facilitate the determination and request of resources a node may wish to reserve. The resources include a plurality of carriers that are shared with other nodes. In an approach, the node determines a condition related to the plurality of carriers; creates an ordering of the plurality of resources; and transmits a resource utilization message (RUM) for one or more of the plurality of resources based on the ordering and the condition.

Abstract: Contention for a resource in a multi-resource system is resolved by separately resolving contention for each resource. In some cases where two or more entities contending for a resource are associated with equal priorities, lexicographic ordering is used to resolve contention between these entities. In some cases where two or more entities contending for a resource are associated with equal priorities, a random probability-based scheme is used to resolve contention between these entities. Also, different types of schemes may be used to resolve contention for different resources.

Abstract: An adaptive scheme controls the transmission of interference management messages by wireless nodes. For example, the adaptive scheme may be used to determine whether and/or how to transmit resource utilization messages. Such a determination may be based on, for example, comparison of a quality of service threshold with a current quality of service level associated with received data. A quality of service threshold may be adapted based on the effect of previously transmitted resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on the frequency at which the wireless node transmits resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on information received from another wireless node. An adaptation scheme also may depend on the type of traffic received by a given wireless node. A quality of service threshold also may be adapted based on throughput information.

Abstract: Techniques for deriving a high quality channel estimate are described. A first channel impulse response estimate (CIRE) having multiple channel taps is derived, e.g., by filtering initial CIREs obtained from a received pilot. A threshold parameter value is selected based on at least one criterion, which may relate to channel profile, operating SNR, number of channel taps, and so on. A second CIRE is derived by zeroing out selected ones of the channel taps in the first CIRE based on the threshold parameter value. The average energy of the channel taps may be determined, a threshold may be derived based on the average energy and the threshold parameter value, and channel taps with energy less than the threshold may be zeroed out. A memory may store threshold parameter values for different operating scenarios, and a stored value may be selected for use based on the current operating scenario.

Abstract: Frame structures and transmission techniques for a wireless communication system are described. In one frame structure, a super-frame includes multiple outer-frames, and each outer-frame includes multiple frames, and each frame includes multiple time slots. The time slots in each super-frame are allocated for downlink and uplink and for different radio technologies (e.g., W-CDMA and OFDM) based on loading. Each physical channel is allocated at least one time slot in at least one frame of each outer-frame in the super-frame. An OFDM waveform is generated for each downlink OFDM slot and multiplexed onto the slot. A W-CDMA waveform is generated for each downlink W-CDMA slot and multiplexed onto the slot. A modulated signal is generated for the multiplexed W-CDMA and OFDM waveforms and transmitted on the downlink. Each physical channel is transmitted in bursts. The slot allocation and coding and modulation for each physical channel can change for each super-frame.

Abstract: To transmit data in a manner to mitigate the deleterious effects of delay spread, the expected coverage areas for multiple transmissions to be sent in multiple time slots are initially determined. Cyclic prefix lengths for these transmissions are selected based on the expected coverage areas. The cyclic prefix length for each transmission may be selected from among a set of allowed cyclic prefix lengths based on the expected coverage area for that transmission, the pilot staggering used for the transmission, and so on. For example, a shorter cyclic prefix length may be selected for each local transmission, and a longer cyclic prefix length may be selected for each wide-area transmission. The selected cyclic prefix lengths may be signaled to the terminals. The transmissions are processed (e.g., OFDM modulated) based on the selected cyclic prefix lengths. The cyclic prefix lengths may be selected periodically, e.g., in each super-frame.
