摘要： A system for joint reverse link access and traffic channel overload control in a cellular network includes relieving the reverse link total loading to optimize resource utilization and distribution among different types of mobile device users. The cellular network includes a plurality of mobile stations that wirelessly communicate with a base station over a reverse link, using a CDMA or similar communications protocol. A joint access and traffic overload control module creates an access channel load relief plan, a traffic channel load relief plan and then relieves the total loading of the reverse link based upon both the access channel load relief plan and the traffic channel load relief plan.

摘要： In one embodiment the method includes allocating, for a mobile, forward link resources for transmitting data over a shared forward link data channel without allocating reverse link resources for reverse link data transmission in association with the allocated forward link resources. At least a portion of the received data is repeatedly sent to the mobile on the shared forward link data channel over a time division multiple access air interface using the allocated forward link resources until an acknowledgement is received from the mobile or a number of transmissions have taken place.

摘要： The present invention provides a method and an apparatus for controlling transmission power of a wireless unit. The method includes providing a power control in a reverse link to a network that transmits data on a traffic channel in a bursty manner based on a performance metric of a channel with continuous transmission of other data than on the traffic channel. To provide a power control in a reverse link of a spread-spectrum wireless data network a method and an apparatus are provided for combining performance of a quality of service from at least one of a first quality feedback channel and a second quality feedback channel with that of a pilot channel and providing an outer-loop power control in said reverse link for a wireless communication on a traffic channel based on said combined performance of the quality of service to control transmission power of a wireless unit. A quality of service metric may be associated with one or more channels of the reverse link to determine performance of such a channel when transmission of data on a traffic channel is bursty in nature. Using a performance metric, such as a quality of service metric of a pilot channel, a power control in the reverse link may be provided when data is not transmitted on the traffic channel, e.g., in a bursty traffic channel to control transmission power of a wireless unit. In this manner, the transmission power of the wireless unit may be controlled based on an outer-loop power control that provides a continuous control for a non-continuous transmission.

摘要： To recover the bits from various users in an asynchronous CDMA communications system, samples of the received signal are processed using blocks of code coefficients. Each code coefficient block includes the sequence of code coefficients for each user which formed the received signal samples. Each sequence has the same number of code coefficients and this number is equal to the product of a predetermined number of bit intervals and the number of code coefficients per bit interval. Processing of the received signal samples using this block formation completely eliminates interference including the so-called leading and lagging edge effects and can be implemented with blocks that include the code coefficients in one or more bit intervals.

摘要： A CDMA system embodying apparatus and methods operates to reduce the effects of the multiple access interference in order to increase the channel capacity and achieve greater efficiency in the use of a given frequency bandwidth. Reception of CDMA radio transmissions is in multiple stages is which the multiple access interference is estimated after the first stage. This estimated multiple access interference is subtracted from the original received input, and the detection of the intended signal is performed on the signal having the reduced multiple access interference.

摘要： A method for compressing data employing vector quantization is achieved by calculating the norm of an input vector and identifying a reference codebook vector which has a norm which is closest to the norm of the input vector. The distance between the input vector and the reference codebook vector selected is computed and employed to identify a vector space about the reference vector containing a subset of codebook vectors one or more of which may be closer to the input vector than the initially selected reference vector. The closest codebook vector is selected iteratively without the necessity of searching every vector in the codebook.

摘要： In one embodiment, a relationship is determined between radio link protocol (RLP) sequence numbers in received RLP packets and real-time protocol (RTP) sequence numbers of RTP packets represented by the received RLP packets. A RTP sequence number associated with a compressed RTP packet is determined based on the determined relationship and at least one of the RLP sequence numbers of the received RLP packet or packets forming the compressed RTP packet. The compressed RTP packet does not include a RTP sequence number.
