Abstract: Uplink control channel management is disclosed in which a user equipment receives a configuration for multiple uplink control channels for transmission to multiple nodes in multiflow communication with the UE. The UE generates the uplink control channels based on the configuration, wherein each of the uplink control channels is generated for a corresponding one of the nodes. The UE then transmits each of the uplink control channels to the corresponding node. For UEs capable of multiple uplink transmissions, in which the UE communicates with at least one of the nodes over multiple component carriers (CCs), the configuration may designate with of the multiple CCs the UE should transmit the uplink control channel for that node. For UEs capable of only single uplink transmissions, the configuration may designate the transmission of the uplink control channels in either frequency division multiplex (FDM) or time division multiplex (TDM) schemes.

Abstract: Methods, systems, and devices are described for multi-carrier communications involving one or more TDD component carriers and one or more FDD component carriers in a wireless communications network. Some described embodiments are directed to systems and methods for multi-carrier communications for a half-duplex device. The described methods, systems, and devices may simplify multi-carrier communications, such as the determination of hybrid automatic repeat request (HARQ) and/or scheduling timing with FDD + TDD carrier aggregation.

Abstract: Techniques to mitigate inter-cell interference using joint time and frequency division are described. A frequency band is divided into multiple non-overlapping frequency subbands. The transmission timeline is divided into T in and T out time intervals. Data is exchanged with users in at least one inner region of a cell on the entire frequency band in the T in time intervals. Data is exchanged with users in multiple outer regions of the cell on the multiple frequency subbands in the Tout time intervals. The frequency band may be partitioned into three frequency subbands. Data may then be exchanged with users in first, second and third outer regions on first, second and third frequency subbands, respectively. The regions in which the users are located may be determined based on pilot and/or other measurements.

Abstract: Systems and methods are provided in a synchronous wireless communication system 100 which enable data to be transmitted between wireless mobile user equipment 110 and base stations 120 without identifying information embedded in the packets 401, thus reducing the transmission overhead. Packets are reordered at base stations 120 based upon a prearranged transmission scheme in which a retransmission for a failed packet is expected in the corresponding HARQ instance of the next group.

Abstract: Method and apparatus for a channel sensitive scheduler for scheduling transmissions in a communication system. The scheduler is defined by a priority function of the channel condition as determined by amount of transmission power needed by a mobile station. In one embodiment the channel condition is determined based on the transmission pilot power of each mobile station and is used to calculate a priority value for each mobile station. The mobile stations are then scheduled to transmit based on the priority value.

Abstract: A method and apparatus for determining the data rate of a reverse link communication. An embodiment includes transmitting at a null rate on the communication channel only when the station is not transmitting voice, signaling, or data. An embodiment includes determining a maximum requested rate based on the normalized average pilot transmit power and the pilot reference value, and determining the timing of the rate request. An embodime nt involves determining a maximum transmission rate. An embodiment involves determining sufficient power and a power-control set point.
