摘要： Aspects relate to a flexible interleaving scheme that provides frequency diversity to randomizes interference Frequency diversity groups can be utilized, wherein control channel elements (CCEs) gain greater frequency diversity for a given number of mini-CCEs (e.g., subset of CCEs). A frequency diversity group index is permuted according to a bit reversed scheme to facilitate control channel elements with a small number of mini-CCEs to also gain sufficient frequency diversity.

摘要： Systems and methodologies are described that facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment. For instance, relative locations of a PSC and a SSC in a radio frame can be a function of a parameter. Further, a PSC sequence utilized to generate PSCs can be selected based upon a parameter. Moreover, inclusion or exclusion of PSCs from a radio frame can be a function of a parameter. Additionally or alternatively, pseudo random sequence mappings (e.g., to cell IDs, tone locations) can be a function of a parameter. Example parameters can be whether the base station is part of a TDD or a FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or a femto cell, or whether the base station is associated with a unicast or a multicast system.

摘要： Systems and methodologies are described that facilitate interleaving encoded control channel information for transmission over an uplink channel. The encoded control channel information, for example, can include encoded Channel Quality Indicator (CQI) information, encoded Precoding Matrix Indicator (PMI) information, and/or Rank Indicator (RI) information. CQI information, PMI information, and/or RI information can be encoded at an access terminal, for instance, by applying a punctured Reed Muller block code to generate a sequence of encoded bits. The encoded bits can be interleaved to reorder the sequence utilizing one or more interleaving approaches. Examples of interleaving approaches that can be leveraged include prime number based interleaving, generalized bit reversal interleaving, column-row interleaving with column bit reversal, and/or M-sequence based interleaving. Further, the reordered sequence of encoded bits can be transmitted to a base station over an uplink channel.

摘要： Systems and methodologies are described that facilitate employing flexible signaling of resource block assignments on a control channel. Resource blocks associated with an uplink or downlink channel can be split into a plurality of groups, and group-specific signaling constraints can be utilized with each of these groups. For example, the group-specific signaling constraints can relate to minimum resource block allocation units, signaling structures (e.g., bitmap structure, contiguous allocation structure, tree-based structure, . . . ), and the like utilized for sending assignment indications that allocate resource blocks within the respective groups. Further, an access terminal can have a common understanding of the group-specific signaling constraints; thus, a received assignment indication can be deciphered by the access terminal by utilizing the group-specific signaling constraints.

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： System(s) and method(s) are provided for inter-cell interference management in a wireless communication system. A base station perform interference management by conveying and receiving load indicator messages over a backhaul communication link to disparate neighboring base stations that serve interfering mobile stations. Reporting of load indicators takes place according to a reporting policy that is event-based, and accounts for variations of interference metrics over available time-frequency resources. Communication with neighboring base stations is limited to a monitoring interference set, which can be determined statically, according to deployment characteristics of a wireless network, or the set can be adjusted dynamically according to a set of received UL signals or a set of DL CQI measurement reports. Reporting policy and interference set can be autonomously adapted to optimize backhaul traffic as well as interference control.
