摘要： Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to estimation of an uplink channel capacity. In an aspect, provided is a method of wireless communication, which may include determining whether a current transmit time interval (TTI) is relevant for computing the uplink channel capacity estimate, determining the transmission type of the current TTI where the current TTI is relevant, determining whether data is transmitted during the current TTI, computing a data capacity value based on at least one upload channel parameter, summing the data capacity values of TTIs from a window length start TTI to the current TTI to generate a data capacity sum, computing the uplink channel capacity estimate as a ratio of the data capacity sum to a total time period of all relevant TTIs during a window length interval, and accordingly adjusting a transmission rate of output traffic.

摘要： In a wireless communications system, a serving base station performs outer and closed power control for an overhead channel and a traffic channel for data, either of which can carry an acknowledgement (Ack) channel and Channel Quality Indicator (CQI) channel on an uplink from User Equipment (UE). In an exemplary aspect, data packet communication is implemented in 3GPP LTE Rel. 8 wherein the uplink has a Single Carrier Frequency Division Multiplex (SC-FDM) uplink waveform. The UE performs open loop power control by a determining transmit power spectral density value by using received energy per symbol for a reference signal.

摘要： Methods, systems, and devices are described for receive chain diversity processing in a mobile wireless device. When data is not being received at the mobile device, the diversity receive chain(s) may be disabled in order to reduce power consumed at the mobile device. The diversity receive chain(s) may be enabled/disabled according to one or more different algorithms based on idle time from the receipt and/or transmission of data. The amount of idle time that triggers the disabling of a diversity receive chain may be adaptive based on historical usage of the mobile device, or based on activity on the transmit chain of the mobile device.

摘要： A method for processing forward link channel signals generated by a CDMA base station includes time sharing by several mobile stations of spreading codes, which are orthogonal codes such as Walsh Code, and code-combining soft/softer handoff across sectors in the mobile station active set to increase dimensions on the CDMA2000 and WCDMA downlink while minimizing intra-sector interference. Since different parts of a packet or frame are transmitted to the user by the different base stations in the active set, earlier decoding and therefore early packet termination is enabled.
