摘要： Communication systems, such as the long term evolution (LTE) advanced (LTE-A) of the third generation partnership project (3 GPP) may benefit from various enhancements. These enhancements can include LTE time division duplex (TDD) enhancements for traffic adaptation and uplink (UL)-downlink (DL) interference management. A method can include determining whether a first cell, in a network including the first cell and a second cell, autonomously selects a time division duplex uplink-downlink configuration. The method can also include sending an authority indicator to a base station of the first cell regarding a determination of whether the first cell is to autonomously select the configuration.

摘要： A method for neighbor cell assisted TDD configurations is described. The method includes receiving, from a serving cell, a first configuration. The first configuration is a cell specific configuration which indicates a first set of individual configurations for each of a plurality of SFs. A second configuration is received from the serving cell. The second configuration is a UE specific configuration which indicates a second set of individual configurations for each of the plurality of SFs. The method includes determining whether a given SF is configured differently in the first configuration than in the second configuration. In response to determining that the given SF is configured differently in the first configuration than in the second configuration, the method also includes communicating, with a neighbor cell, in the given SF as configured in the second configuration. Apparatus and computer readable media are also described.

摘要： There is a pattern for downlink almost blank sub frames ABSFs for a first network node (e.g., macro eNB) operating in a first component carrier (e.g., PCell). For a user equipment UE operating with the first network node on the first component carrier and also with a second network node on the second component carrier, then either or both of the following are imposed. The UE is scheduled on the first component carrier such that no uplinic control information UCI from the UE is scheduled for any uplink subframe in the first component carrier which maps from any of the ABSFs; and the UE is scheduled on the second component carrier such that UCI from the UE is scheduled only for an uplinic subframe in the second component carrier which maps from any of the ABSFs. By example, the UCI includes either/or ACKs and NACKs corresponding to data sent downlink to the UE.

摘要： Systems and techniques for contention based transmission in a cellular network. A physical uplink shared channel is used for contention based transmission by a device such as a user equipment, based at least in part on information provided by a physical uplink control channel associated with the physical uplink shared channel. In addition, a base station such as an eNodeB may respond to a physical uplink shared channel by providing a common physical downlink shared channel providing acknowledge ment/negative acknowledgement information. In addition, the base station may provide a physical downlink control channel indicating the common physical downlink shared channel.
