Abstract:
An apparatus and method for dynamically changing an uplink and downlink ratio configuration is disclosed herein. An evolved Node B (eNodeB) operating in a wireless communications network transmits a System Information Block Type 1 (SIB1) including first uplink and downlink ratio configuration information. The eNodeB also transmits in at least one downlink subframe of a radio frame configured in the first uplink and downlink ratio configuration second uplink and downlink ratio configuration information. The second uplink and downlink ratio configuration information is included in a downlink control information (DCI) message. The DCI message is included in the at least one downlink subframe of the radio frame.
Abstract:
Technology for conditional hybrid automatic retransmission re-quest (HARQ) mapping for carrier aggregation (CA) is disclosed. One method can include a user equipment (UE) determining when a subframe for physical downlink shared channel (PDSCH) transmission is configured for downlink semi-persistent scheduling (SPS). The subframe configured for downlink SPS can generate a first condition. The UE can generate HARQ-ACK states for the first condition for a HARQ bundling window with discontinuous transmission (DTX) padding for a secondary HARQ bundling window size for a secondary cell (SCell) and a primary HARQ bundling window size for a primary cell (PCell). The UE can generate HARQ-ACK states for a second condition for the HARQ bundling window with DTX padding including a DTX padding exception. The second condition can include conditions not covered by the first condition. The DTC padding exception can generate a set of HARQ-ACK states to uniquely define each padded HARQ-ACK state.
Abstract:
Embodiments of a system and method for reporting uplink control information (UCI) are generally described herein. In some embodiments, a first and second component carrier (CC) is provided for a user equipment (UE). The first and second CC are configured with transmission mode (TM) 10 and TMs 1-9, respectively. A first channel state information (CSI) report for the first CC with TM 10 and a second CSI report for the second CC with at least one of TMs 1-9 are scheduled for transmission in a subframe. A collision is detected between the first and second CSI reports. Priority is assigned to the first CSI report or the second CSI report based on a prioritization parameter. The prioritized CSI report is transmitted based the prioritization parameter.
Abstract:
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for downlink resource scheduling in wireless networks. In some embodiments, the scheduling may include multi-subframe cross carrier scheduling utilizing downlink control information. Other embodiments may be described and/or claimed.
Abstract:
A Second Synchronous Signal (SSS) for a 3GPP LTE downlink signal is generated in such a way that a legacy User Equipment (UE) can determine whether the downlink signal comprises a legacy downlink signal or a New Carrier Type (NCT) downlink signal, which is unavailable to a legacy UE. One exemplary embodiment provides that a first binary sequence and a second binary sequence are generated in which the first and second binary sequences are part of the SSS for the downlink signal. The first binary sequence is multiplied by a first scrambling sequence, and the second binary sequence by a second scrambling sequence in which the first and second scrambling sequences are selected to indicate that the downlink signal is a new carrier type downlink signal. Other exemplary embodiments provide that an order of the first and second scrambling sequences indicates whether the downlink signal is a NCT downlink signal.
Abstract:
An evolved node (eNB) operable to transmit a Time Division Duplex (TDD) uplink-downlink (UL-DL) reconfiguration in a heterogeneous network (HetNet) is disclosed. The eNB can receive, from a user equipment (UE), a UE capability report that indicates the UE supports a TDD UL-DL reconfiguration functionality. The eNB can transmit, to the UE, a configuration to enable TDD UL-DL reconfiguration at the UE. The eNB can transmit, to the UE, a TDD UL-DL reconfiguration signal in a downlink control information (DCI) message. The UE can be configured to update a TDD UL-DL configuration of the UE based on the TDD UL-DL reconfiguration signal transmitted on a physical downlink control channel (PDCCH) in preconfigured downlink or special (DL/S) subframes by the eNB.
Abstract:
An apparatus and method for managing interference to facilitate allocation of a dynamic uplink and downlink configuration are disclosed herein. Determining whether a first cell causes interference less than a pre-determined threshold level to one or more neighboring cells or whether flexible subframes of radio frames associated with the one or more neighboring cells operate as downlink subframes. In response to the determining condition being met, allocating a first flexible subframe of a first radio frame associated with the first cell to operate as a downlink subframe at normal transmit power level. In response to the determining condition not being met, allocating the first flexible subframe of the first radio frame associated with the first cell as one of a downlink subframe operating in a reduced transmit power level or as an uplink subframe.

Abstract:
Devices, methods, computer-readable media, and systems configurations for determining a hybrid automatic repeat request (HARQ)-acknowledgment (ACK) codebook in wireless communication networks. A user equipment (UE) may communicate with a plurality of serving cells, wherein at least two of the serving cells include different time division duplexing (TDD) uplink-downlink (UL-DL) configurations. The UE may determine a value based on a downlink assignment index (DAI), and determine a number of downlink subframes or special subframes that are included in a bundling window associated with an uplink subframe. Further, the UE may select the lesser of the determined value or the determined number of downlink subframes or special subframes included in the bundling window to correspond to a number of subframes for which the UE needs to feedback HARQ-ACK bits for the first serving cell.
Abstract:
An apparatus is provided for use in a User Equipment, UE, comprising an input to receive an information element, IE, during a device-to-device, D2D, communication session with another UE, the IE indicating whether or not the UE is to send a measurement report; a processing section to determine based on the indication; and an output to control transmission by the UE, the processing section being arranged to suppress participation in measurement reporting when it is determined that a measurement report is not to be sent. A related apparatus is provided for use in an evolved Node B, eNB, and related methods are also provided.
