摘要： Techniques for assigning acknowledgement (ACK) resource to a user equipment (UE) in a wireless communication system are described. In one design, a first parameter indicative of radio resources (e.g., the lowest index of at least one physical resource block) allocated to the UE for data transmission may be obtained. A second parameter indicative of another resource (e.g., a cyclic shift of a reference signal sequence) assigned to the UE for data transmission may also be obtained. The first and/or second parameter may be restricted, and each restricted parameter may be limited to a set of allowed values among all available values for the parameter. ACK resource assigned to the UE for data transmission may be determined based on the first and second parameters. In one design, sequential first parameter values may be mapped to sequential ACK resources indices. In another design, mirror mapping with different mapping directions may be used for different allowed values of the second parameter.

摘要： Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.

摘要： The described aspects include methods and apparatus for aggregating carriers over a backhaul link between a relay and an evolved Node B (eNB). A first set of subframes of at least a first carrier of a plurality of carriers configured for communicating with an eNB over a backhaul link can be determined. A second set of subframes of at least a second carrier of the plurality of carriers configured for backhaul link communications is also determined, wherein the second set of subframes are different from the first set of subframes. Data received over a plurality of access link carriers can then be communicated to the eNB over the first carrier and the second carrier based at least on the first set of subframes and the second set of subframes.

摘要： Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.

摘要： Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.
摘要翻译：可以基于TDD配置中的特殊子帧配置允许下行链路传输来分配用于确认（ACK）和/或否定确认（NAK）的比特。对于载波聚合，ACK / NAK比特可以仅分配给允许下行链路传输的分量载波（CC）中的特殊子帧。此外，例如，如果单个CC被配置为允许在其特殊子帧之一上的下行链路传输，则可以将ACK / NAK比特分配给所有CC特殊子帧。 ACK / NAK位也可以分配给所有特殊子帧。

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a first message to reconfigure an uplink transmission mode of a user equipment (UE) from a first uplink transmission mode to a second uplink transmission mode is transmitted. Further, a reconfiguration scheme to assure at least one of two or more second messages are recognizable by the UE during a transition period after transmission of the first message is implemented. In another example, a UE and eNB may be equipped to respectively transmit and receive a first message to reconfigure a SRS mode used by a UE. In such an aspect the first message may respectively indicate and be used to determine an SRS transmission port specified in a field capable of indicating a number of SRS transmission ports that is greater than a number of physical UE antenna ports.

摘要： Techniques for receiving reference signals from multiple nodes and determining channel state information (CSI) for the nodes are disclosed. A user equipment (UE) may determine and report CSI for the multiple nodes to support data transmission to the UE. The nodes may transmit reference signals based on different configurations. The configuration for each node may indicate when, where, and how the node transmits its reference signal. The UE may determine CSI for different nodes and/or different combinations of nodes based on the reference signals transmitted by these nodes as well as an indication of which subframes to use to determine each CSI reported by the UE. The UE may report different CSIs for different subframes and may receive data transmission sent by a single node or a combination of nodes based on the reported CSIs.

摘要： Techniques for sending ACK/NACK information in a multi-carrier wireless communication network are disclosed. In one aspect, a plurality of ACK/NACK transmission techniques are selectively employed by a multi-carrier user equipment (UE) to reduce the number of bits of ACK/NACK information to send and/or increase the number of payload bits available for sending the ACK/NACK information. The ACK/NACK transmission techniques may include an orthogonal sequence reduction technique, a channel selection technique, a spatial bundling technique, a carrier bundling technique, and/or a subframe bundling technique. The ACK/NACK transmission techniques may be prioritized based on the number of carriers on which data transmissions are received, a payload size available for carrying ACK/NACK information, and/or other factors. The multi-carrier UE can utilize different ACK/NACK transmission techniques in connection with different subsets of its configured carriers.
