摘要： Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier. The UE may monitor for the first DCI format(s) on the first carrier to detect DCI sent to the UE. The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.

摘要： Systems, methods, apparatuses, and computer program products are described for power headroom reporting. A mobile device may identify a transmit power associated with each of a number of independently power controlled channels on one or multiple carriers configured for use by the mobile device. The transmit power may relate to one channel that is an uplink control channel, and one or more additional channels that are uplink shared channels. The identified transmit power of one channel (e.g., the uplink control channel) may be a virtual transmit power, while other identified transmit powers may be measured transmit powers for actual transmissions. The identified transmit powers may be added up, and the power headroom available for the mobile device may be calculated using the accumulated transmit powers. The mobile device may transmit a power headroom report to a base station.
摘要翻译：描述了功率余量报告的系统，方法，设备和计算机程序产品。移动设备可以识别与配置为由移动设备使用的一个或多个载波上的多个独立功率控制信道中的每一个相关联的发射功率。发射功率可以涉及作为上行链路控制信道的一个信道和作为上行链路共享信道的一个或多个附加信道。所识别的一个信道的发射功率（例如，上行链路控制信道）可以是虚拟发射功率，而其他识别的发射功率可以是用于实际传输的测量的发射功率。所识别的发射功率可以相加，并且可以使用累积的发射功率来计算可用于移动设备的功率余量。移动设备可以向基站发送功率余量报告。

摘要： Systems and methodologies are described that facilitate system frame number (SFN) indication and identification during a random access procedure (e.g., associated with a handover). As described herein, a target cell can configure one or more Random Access Responses (RARs) designated for transmission to a terminal during the access phase of a handover to include the SFN of the target cell. Techniques are further described herein by which the target cell can include SFN information in a sub-header associated with a RAR, in the payload of a RAR, and/or in other appropriate manners. In addition, the target cell can configure one or more flags of the RAR to indicate the presence of SFN information. Upon receiving a RAR with embedded SFN information, a terminal can utilize the SFN for operations such as frequency hopping or uplink resource configuration as described herein.

摘要： A wireless communication system implementing Carrier Aggregation (CA) allows activation and deactivation of certain component carriers. Transmit power on an uplink component carrier being reactivated may be controlled by predetermining appropriate power control parameters to be used upon reactivation. The predetermined power control parameters may depend on a last known power control state of the deactivated component carrier or may be reset to apply an initial low power state.
摘要翻译：实现载波聚合（CA）的无线通信系统允许某些分量载波的激活和去激活。重新激活的上行链路分量载波上的发射功率可以通过预先确定在重新激活时使用的适当功率控制参数来控制。预定功率控制参数可以取决于去激活分量载波的最后已知的功率控制状态，或者可以被复位以施加初始低功率状态。

摘要： Certain aspects of the present disclosure relate to techniques for user-specific search space design for multi-carrier operation in Long Term Evolution Advanced (LTE-A) systems. The user-specific search space can be designed for searching Physical Downlink Control Channels (PDCCHs) transmitted on one component carrier (CC) that schedules Physical Downlink Shared Channel/Physical Uplink Shared Channel (PDSCH/PUSCH) transmissions on two or more different CCs. In one aspect, multiple independent user-specific search spaces can be designed. In another aspect, one user-specific search space can be randomly derived and then expanded to accommodate search for multiple CCs. In yet another aspect, the search space design can retain randomness in starting search element indices of multiple PDSCH/PUSCH CCs, while overlapping of search spaces for multiple PDSCH/PUSCH CCs can be avoided.
摘要翻译：本公开的某些方面涉及用于在长期演进高级（LTE-A）系统中用于多载波操作的用户特定搜索空间设计的技术。用户特定搜索空间可以被设计用于搜索在两个或多个不同CC上调度物理下行链路共享信道/物理上行链路共享信道（PDSCH / PUSCH）传输的一个分量载波（CC）上发送的物理下行链路控制信道（PDCCH）。在一个方面，可以设计多个独立的用户特定搜索空间。在另一方面，可以随机导出一个用户特定的搜索空间，然后扩展以适应多个CC的搜索。在另一方面，搜索空间设计可以保留多个PDSCH / PUSCH CC的搜索元素索引的随机性，而可以避免多个PDSCH / PUSCH CC的搜索空间重叠。

摘要： Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In one aspect, a UE determines a number of acknowledgement/negative acknowledgement (ACK/NACK) bits for a data transmission on one more component carriers (CCs) based on information obtained from a grant. The grant may be a downlink grant or an uplink grant, and the information obtained may include a number of CCs scheduled for data transmission and/or identifiers of the scheduled CCs. The UE may determine the number of ACK/NACK bits for acknowledging the data transmission based on the number of scheduled CCs and the identifier of each scheduled CC.

摘要： Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.
