摘要： Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.
摘要翻译：本文公开了在无线通信中提供改进的差错控制信令。作为示例，可以在HARQ过程之前的调度的反馈信号之前对HARQ进程进行多个传输，使得接收设备组合多个传输，而不是将其作为单独的传输。以这种方式，可以采用多个传输来增加总体接收能量，而不违反无线通信中的最大发射功率约束。此外，可以基于接收设备处的主要信号强度或基于接收设备的处理能力来配置这些多个传输，从而提供可在宽范围的无线条件下适应高级以及传统UE的灵活协议。

摘要： Systems and methodologies are described that facilitate resource management in a wireless communication system. Various techniques described herein can enable a network cell in a wireless communication system (e.g. a macro cell) to mitigate the effects of interference on other surrounding network cells (e.g., femto cells embedded within the coverage of the macro cell). For example, a network cell can allocate control resources that overlap control resources of a nearby cell and assign resources within the region of overlap only to users that will not cause substantial interference to the nearby cell. As another example, a network cell can utilize a control channelization that partially coincides with a control and/or random access channelization of a nearby cell. The network cell can subsequently elect not to use the control resources in the coinciding region in order to enable the nearby cell to control the effects of interference though data scheduling.

摘要： Certain aspects of the present disclosure relate to techniques for determining resource elements REs used for Coordinated Multipoint (CoMP) transmission schemes. The techniques generally include determining, by a User Equipment (UE), a set of data REs used for Coordinated Multipoint (CoMP) operation. The determination is based on a CoMP scheme and data REs available to particular base stations involved in the CoMP operation. The technique further includes processing data received via the CoMP operation on the determined set of data REs.

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 reporting timing information to facilitate data transmission on a downlink are described. A user equipment (UE) may receive signals from a plurality of cells available for data transmission to the UE. Each cell may have a different propagation delay to the UE. The UE may determine timing information based on the received signals and may report the timing information to one or more of the cells. The timing information may include a receive time of each cell at the UE. The UE may receive a data transmission from at least one cell, which can be selected from the plurality of cells, based on the timing information. The at least one cell may provide a coordinated or a non-coordinated data transmission. A coordinated transmission mode may be determined based on the timing information and can include, for example, a joint transmission, a coordinated beamforming, or a coordinated silencing.
