| Title of Invention | METHOD FOR POWER CONTROL FOR MIXED VOICE AND DATA TRANSMISSIONS |
|---|---|
| Abstract | In a disclosed embodiment, a "voice noise power" is added to an aggregate voice power which is the total voice power used by all users in a cell. The voice noise power is transmitted in addition to the aggregate voice power in order to maintain the total of the aggregate voice power and voice noise power at a predetermined voice power limit. In one embodiment, the voice power limit can be increased or decreased to further improve control over power consumption during voice and data transmission. Further, in order to maintain the power tonsumed by data transmission at a desired level, data noise is transmitted after transmission of a data burst, or in between data bursts, by inserting a pre-determined amount of artificial data into the gaps in data transmission. The data noise is transmitted in addition to the data bursts in order to maintain the total power consumed during data transmission at a desired level. Figure 3 , |
| Full Text | METHOD FOR POWER CONTROL FOR MIXED VOICE AND DATA TRANSMISSION transmission simultaneously, i.e., mixed voice and data transmission, different significantly interfering with one another. One meants of spreading is the referred to as "intra-cell interferrence, including interference of a user's own Figure 1 shows an example of the effect, than data signal transmission can power allocation for the users, leading to increase 118 in aggregate voice power P, within the cell. Thus, for example, power control within cell 203 can be affected Figure 2C shows graph 260, having power axis 261 plotted against time allocation by the power control system in cell 203 is reflected in increase 238 in can lead to over-allocation and under-allocation of power to each user and to the pre-determined voice power limit. Since the aggregate voice power and the voice a spread spectrum communication system. the art. Packer Data Transmission Serial No 08/963,386 filed on November 3,1997, and despreading techniques as orthogonal codes despite added voice noise power example, after data burst 310 and before data burst 312, and again after data burst percentage of voice power limit Pv max 306 rather than allocating the full amount by inserting data noise such as data noise 520 between consecutive data bursts 310 graph 400 as; double-dotted-dashed, stepped line: 406. Extra voice power is power Pv 404 to the value of maximium power limit Pmax 418, described below. Accordingly, total power Pv+d 416 is maintained at a desired level. The additional subsecuent data burst 414, no further adjustments of Pdata 424 are required. As Pv max 506 in accordance with are embodiment. Adapting voice power limit Pv, As seen in graph 500, P v+d 516 remains below maximum power limit Pmax 518. defined amounts for the adjustments can be any amounts between 0% and data noise. 523 when reducing data power Pdata 524 have the effect of eliminating control in the communication system by minimizing the amount of extra power invention is not limited to the particular embodiments decribed hereein. but is WHAT IS CLAIMED IS: CLAIMS 1.
