  • Publication number: 20160374111
    Abstract: In one disclosed embodiment, data information is stored in a buffer in a transmitter. The data information is transmitted on a shared channel and control information for recovering the associated data information is transmitted on a dedicated channel. The shared and dedicated channels can be, for example, different portions of the frequency band. The control information can include a spreading factor used to spread the data at the transmitter. For example, the spreading factor can be the length of the Walsh function orthogonal coding used to spread the data. The control information is received over the dedicated channel before the associated data information is received over the shared channel. The control information is then used to recover the associated data information. For example, knowing the spreading factor from the control information, the correct Walsh function can be selected to de-spread, i.e. to Walsh de-cover, the data information.

  • Patent number: 9509478
    Abstract: System(s) and method(s) are provided for transmitting data code symbols and control code symbols spanning disparate transmission time intervals in the uplink. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. Multiplexing in conjunction with localized and distributed resource scheduling preserves the single-carrier characteristics of a single-carrier frequency division multiple access system.

  • Patent number: 9143288
    Abstract: Techniques for sending control information on a variable control channel are described. Different structures for mapping control information to control channel resources may be used depending on various factors such as operating configuration, the available resources for the control channel, the type(s) of control information being sent, the amount of control information being sent for each type, whether or not data is being sent, etc. In one design, at least one type of control information being sent may be determined and may comprise channel quality indicator (CQI) information, acknowledgement (ACK) information, and/or other types of control information. A structure of the control channel may be determined based on operating configuration (e.g., system configuration such as asymmetry of downlink and uplink allocations) and/or other factors. The at least one type of control information may be mapped to the resources for the control channel based on the structure.

  • Patent number: 8489949
    Abstract: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

  • Patent number: 8477742
    Abstract: Schemes to time-align transmissions from multiple base stations to a terminal. To achieve time-alignment, differences between the arrival times of transmissions from the base stations, as observed at the terminal, are determined and provided to the system and used to adjust the timing at the base stations such that terminal-specific radio frames arrive at the terminal within a particular time window. In one scheme, a time difference between two base stations is partitioned into a frame-level time difference and a chip-level time difference. Whenever requested to perform and report time difference measurements, the terminal measures the chip-level timing for each candidate base station relative to a reference base station. Additionally, the terminal also measures the frame-level timing and includes this information in the time difference measurement only if required. Otherwise, the terminal sets the frame-level part to a predetermined value (e.g., zero).

  • Patent number: 8438447
    Abstract: An encoder receives an input bit stream and generates, based on the input bit stream, a first output bit stream based on at least a first polynomial and a second output bit stream based on at least a second polynomial. The first and second polynomials are each different from each other. The encoder forms a first packet of code symbols, having a first code rate, based on bits from the first output bit stream. A transmitter transmits the first packet. A receiver receives a first negative acknowledgment indicating unsuccessful decoding of the first packet after transmitting of the first packet. The encoder punctures bits from the second output bit stream and forms a second packet of code symbols having a second code rate. The second code rate is different from the first code rate. The transmitter transmits the second packet in response to the receiver receiving the first negative acknowledgment.

  • Patent number: 8363576
    Abstract: Techniques for transmitting voice/data and packet data services such that packet data transmissions have less impact on voice/data transmissions. In one aspect, voice/data and packet data can be multiplexed within a transmission interval such that the available resources are efficiently utilized. In another aspect, the amount of variation in the total transmit power from a base station is controlled to reduce degradation to transmissions from this and other base stations. In a specific method for concurrently transmitting a number of types of data, a first data type (e.g., voice, overhead, and some data) and a second data type are respectively processed in accordance with first and second signal processing schemes to generate first and second payloads, respectively. First and second partitions are then defined in a transmission interval. The first and second payloads are time multiplexed into the first and second partitions, respectively, and the multiplexed payloads are transmitted.
