摘要： A diversity indication method in GERAN/MUROS system, includes the steps: after a user receives a diversity indication, it receives data from two sub-channels, and then carries out diversity combination; if the user does not receive diversity indications, users receive data from subchannel allocated to them. Using the method of this invention, we can carry out diversity indications in GERAN/MUROS system. In this way, users do not need to determine whether current frame is using diversity transmission in all sub-channels by carrying out autocorrelated operations over training sequences 26 bit long in each frame, and the users may demodulate information from another paired subchannel only when they receive diversity indications in subchannel allocated regularly to greatly reduce the user's complexity.

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： A macro eNB (MeNB) triggers a small cell (eLA eNB) to transmit a sequence on a second frequency band using a triggering command that indicates a time to transmit the sequence. On a first frequency band the MeNB triggers at least one user equipment UE to detect the sequence on the second band, and this trigger also has a first indication of when the sequence will be transmitted. From a second indication the MeNB receives on the first band from the at least one UE in response to the triggering of the UE the MeNB can determine whether the UE is located proximate to the small cell. The indication may be as little as a single bit indicating whether the UE detected or not the sequence. The first and second bands may be on first and second component carriers that may not be synchronized to one another, and the aperiodic nature of the triggered sequences and detection reports saves UE power.
