Abstract: A method and apparatus are for communication in a wireless network in which a User Equipment (UE) associated with a first evolved Node B (eNB) experiences interference from a second eNB. The method includes negotiating by the first eNB of the wireless network with a second eNB of the wireless network for a partitioning of subband resources on an uplink. A first subset of subband resources is assigned to the first eNB, and a second subset of subband resources is assigned to the second eNB. A method and apparatus are for communication in a wireless network. The method includes decoding a downlink control channel received during a protected downlink subframe to determine an uplink subframe n containing a protected subband for uplink transmission. The method also includes transmitting data during the uplink subframe n on the protected subband.

Abstract: An indication is used to control how message service information is routed over different domains. For example, an access terminal may be configured with an indication that indicates that a message service is preferred to be invoked over an IP domain or that the message service is not be invoked over the IP domain. The access terminal then delivers message service information based on the value of the indication. In some cases, a network entity generates the indication and sends the indication to the access terminal. In some cases, a domain for delivery of message service information is selected based on a domain that was selected for particular type of traffic.

Abstract: Methods and apparatus for supporting adaptive resource negotiation between evolved node Bs (eNBs) for enhanced inter-cell interference coordination (eICIC) are provided. This resource negotiation may occur via a network backhaul between the eNBs or, in some cases, using over-the-air messages (OAMs). For certain aspects, a first eNB may propose its adaptive resource partitioning information (ARPI) to a second eNB, where the second eNB may accept or reject the proposed resource partitioning. If the second eNB accepts the proposed partitioning, the second eNB may schedule resources, such as subframes, based on the accepted partitioning.

Abstract: Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

A Non-Access Stratum (NAS) layer protocol and/or an Internet Protocol (IP) application, in combination with a set of associated network management messages, can be utilized to exchange network management information between a device and a network. As further described herein, various procedures can be utilized to install a SON policy to a device in order to define device behavior for operations such as collecting and reporting information related to network management.

Abstract: Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering/aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes.

Abstract translation: 无线网络设备之间的干扰问题得到缓解。 当服务于其中UE受到侵略者eNodeB强烈影响的小区范围扩展（CRE）区域中的用户设备（UE）时，演进节点B（eNodeB）可能经历更高的小区负载或更高的干扰。 经历较高小区负载的eNodeB或在更高干扰下的用户设备（UE）通常要求干扰/攻击者eNodeB重新分配其资源中的一些资源。 然而，重新分配资源可能对服务于CRE区域UE的eNodeB产生负面影响。 一方面，新的利用度量度衡量CRE状态，并区分受保护资源和不受保护的资源，如子帧。
