摘要： A method, a computer program product, and an apparatus for separating a cell cluster to two or more cell clusters are provided. The cell cluster may be separated into two or more cell clusters in order to mitigate interference between cells while allowing for TDD subframe configuration flexibility. The method identifies at least one separating cell in a cell cluster, the cell cluster including at least two cells having a common TDD subframe configuration, where a coupling loss between one cell in the cell cluster and at least another cell in the cell cluster is lower than a predefined threshold. The method separates the cell cluster based on the at least one separating cell into at least a first cell cluster and a second cell cluster and sets a first TDD subframe configuration for the first cell cluster and a second TDD subframe configuration for the second cell cluster.

摘要： Aspects described herein generally relate to communicating between a user equipment (UE) and a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell. An indicator can be transmitted from the cell and received by the UE to implement time division duplexing (TDD) on the uplink frequency band. Based at least in part on the indicator, communicating between the UE and the cell can include separating the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell.

摘要： Certain aspects of the present disclosure relate to techniques for cross-carrier indication of TDD (Time Division Duplex) UL (Uplink)/DL (Downlink) subframe configuration. A UE may receive a configuration of a first index for a first cell, wherein the first index is mapped to a first position in a Downlink Control Information (DCI) message. The UE may receive the DCI message in a subframe and determine an indication of a UL/DL subframe configuration for the first cell based on the first index and the DCI message. The UE may communicate with the first cell based on the determined UL/DL subframe configuration for the first cell.

摘要： Aspects of the present disclosure relate to techniques that may help enable the determination of uplink resource allocation in systems that support dynamic uplink-downlink subframe configurations. An example method generally includes receiving signaling indicating a dynamic uplink-downlink (UL-DL) subframe configuration, determining hybrid automatic repeat request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) timing based on a reference UL-DL subframe configuration, and determining HARQ resource allocation based on the dynamic UL-DL subframe configuration.

摘要： Certain aspects of the present disclosure relate to techniques for managing resources for cooperative uplink transmission. A base station may determine different groups for a plurality of user equipments (UEs) participating in cooperative uplink transmission, and transmit mode configurations indicating whether or not UEs in each group are configured to transmit data as a data source or to relay data received from another UE configured to transmit data as a data source. A UE may participate, with one or more other UEs, in cooperative uplink transmission to the base station, wherein each UE belongs to a group. The UE may determine, for a transmission time interval (TTI), at least one operation to perform for the cooperative uplink transmission based, at least in part, on a group number of a group to which the UE belongs and an index of the TTI.

摘要： A mobile station receives a downlink control structure in a first carrier, where the downlink control structure indicates that control information for the mobile station is on a second, different carrier. The mobile station decodes the control information in the second carrier, where the control information specifies resource allocation of a wireless link for the mobile station. More specifically, according to some implementations, the control channel in the first carrier specifies the resource allocation for an extended control channel in the second carrier, where the extended control channel specifies the resource allocation for traffic data of a wireless link for the mobile station.

摘要： The present invention provides for an improved application of signal strength weightings in a SDMA sectorized cellular network. The improved signal strength weightings application is conducted through the improved selection of weightings from a new codebook subset or by the selection of weightings from a larger codebook subset. In a further embodiment, an antenna beam index or bit map can be used to select the best beam(s) in a SDMA sectorized cellular network. In another embodiment, a field or factor in an uplink or downlink transmission packet can designate which directional transmission beam is best suited for the transmission or when the directional transmission beam should be activated.
