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： 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.

摘要： Different sequence resources can be allocated to a mobile device where the mobile device can exclusively uses the sequence resource with regard to a base station during a communication session. However, if another mobile device using another base station is assigned a matching sequence resource, then there can be interference if the mobile devices are relatively close enough together. Therefore, randomization of the sequence resources can take place—moreover, a cyclic shift result can be employed in sequence resource allocation to attempt to minimize interference.

摘要： Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

摘要： Techniques for sending a MIMO transmission using a combination of cyclic delay diversity and precoding are described. A set of delays (e.g., zero delay, small delay, and large delay) for cyclic delay diversity and a set of precoding matrices may be supported. In one design, a Node B may select a delay specifically for a UE or for a set of UEs served by the Node B. In another design, a UE may evaluate different combinations of precoding matrix and delay, determine the combination with the best performance, and send this combination of precoding matrix and delay to the Node B. The Node B may perform precoding with the precoding matrix and then processing for cyclic delay diversity based on the selected delay. Alternatively, the Node B may perform processing for cyclic delay diversity based on the selected delay and then precoding with the precoding matrix.
