摘要： The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for network management through a hierarchical architecture with a control functionality of a network server (e.g., C-SON) in relationship to clusters comprising eNBs (access points), and for implementing coordinated multi-point (CoMP) transmission and reception in conjunction with inter-cell interference coordination (ICIC) in wireless networks such as LTE wireless networks. In particular, embodiments of the invention describe control and coordination mechanisms among the network elements for different network architectures and use-case scenarios. Such mechanisms may be managed by a centralized self-organizing network controller such as C-SON and hierarchically via localized controllers (such as cluster coordinators) residing in macro eNBs depending on system architectural constraints and network state. A fault-tolerant mechanism then may be defined to recover from failure of controlling sub-elements so that the network remains stable at all times.
摘要翻译：说明书和附图提出了一种用于网络管理的新方法，装置和软件相关产品（例如，计算机可读存储器），其通过具有与包括eNB的集群相关联的网络服务器（例如，C-SON）的控制功能的分级架构（接入点），并且用于在诸如LTE无线网络的无线网络中结合小区间干扰协调（ICIC）来实现协调的多点（CoMP）发送和接收。特别地，本发明的实施例描述了用于不同网络架构和用例场景的网络元件之间的控制和协调机制。这样的机制可以由诸如C-SON的集中式自组织网络控制器管理，并且根据系统架构约束和网络状态分层地经由驻留在宏eNB中的集中式控制器（例如集群协调器）来管理。然后可以定义容错机制以从控制子元件的故障中恢复，使得网络始终保持稳定。

摘要： A base station employs control signaling for contention-based uplink access from user equipment devices to the base station. Contention-based access configuration is performed via physical downlink control channel signaling. Configuration data sent to the user equipment devices identifies multiple contention-based access zones, along with minimum power headroom values for each contention-based access zone. A probability factor may be used to lower collision possibility by influencing whether the user equipment devices perform contention-based uplink access.

摘要： A user equipment (UE) operating in an Orthogonal Frequency Division Multiplexing communication system transmits Layer 1 and Layer 2 user data non-associated and user data associated control signaling on an uplink by puncturing user data information with the user data non-associated and user data associated control signaling to produce a data stream wherein the control signaling and user data information are multiplexed. The UE then conveys the punctured data stream to a radio access network via an air interface. The communication system further provides for a selection of a coding and modulation for the control signaling based on a modulation and coding scheme of the user data and a transmission scheme that is applied for transmission of the user data information over the air-interface.

摘要： Various embodiments are described which can serve to mitigate interference between the control channel signaling of adjacent sectors/cells. Potentially, these techniques may have the benefit of reducing the system resource drain caused by control channels, particularly control channels in high frequency-reuse, OFDMA systems. A transmitting device (101) transmits primary control channel information to a plurality of user devices (102). The primary control channel information includes an indication that a first OFDMA resource region (e.g., 320 or 330) is assigned to at least one user device of the plurality of user devices. The transmitting device correspondingly transmits secondary control channel information to the at least one user device using the first OFDMA resource region.

摘要： In an Orthogonal Frequency Division Multiplexing communication system, a user equipment reports channel quality information that is sufficient to construct a fading profile of a frequency bandwidth and that does not consuming the overhead resulting from the reporting of CQI for every sub-band of the frequency bandwidth. In the communication system, the frequency bandwidth may be represented by multiple sub-band levels, wherein each sub-band level comprises a division of the frequency bandwidth into a number of sub-bands different from the number of sub-bands of the other sub-band levels. The user equipment measures a channel quality associated with each sub-band of a sub-band level of the multiple sub-band levels, selects a sub-band of the sub-band level based on the measured channel qualities, and reports channel quality information associated with the selected sub-band to a radio access network.
