摘要： A method and apparatus are provided for dynamically controlling a high speed wireless communication system to optimize utilization of system resources and increase system throughput. The invention operates to determine an allocation of wireless transmission resources to each user application served by the wireless system in a manner to optimize transmission resources while meeting required QoS criteria for the served user application. After all user applications have been provided a transmission resource allocation in this manner, the total transmission resources so allocated are determined and compared with a ceiling transmission resource level for the wireless system. A portion of the difference between the ceiling and currently allocated transmission resource levels is then made available, according to the invention, to the served user applications in proportion to the initial allocation provided each user application. An admission control methodology is also provided which is implemented in a cooperative relationship with the further resource allocation process of the invention.

摘要： A method is provided a wireless system for reliably transmitting context information in robust header compression at low signal energies. More particularly, the methodology of the invention provides an elongated virtual Transmission Time Interval (Super TTI) for the first few (in particular, the first) non-compressed packet (that includes upper layer headers) of a packet stream transmitted using ROHC compression. Improved reception reliability for the uncompressed packet, in particular to decode the headers, results by application to the Super TTI of a combination of TTI Bundling techniques, RLC segmentation and association with multiple HARQ processes and use of enough HARQ rounds.

摘要： A system and method for wireless communication includes multiplexing an EUDC downlink control channel so that it is transmitted like a downlink dedicated channel (DL-DPCH). The EUDC downlink control channel can be multiplexed with the DL-DPCH by code or by both code and time. The EUDC downlink control channel may be multiplexed with a downlink dedicated physical data channel (DL-DPDCH), a downlink dedicated physical control channel (DL-DPCCH), or both. In one embodiment, the EUDC downlink control channel is multiplexed by adding a multicode channel to a current DL-DPCH and treating the EUDC downlink control channel as a dedicated channel with power control functionality.

摘要： A method for reliably transmitting signaling information is provided. One type of signaling information is transmitted over a primary control channel. The signaling information that is to be transmitted over the primary control channel is defined as a set of particular information. Other signaling information are conveyed over a secondary control channel. Prior to transmission, the information to be conveyed over the secondary channel is scrambled in accordance with a particular scrambling procedure that indicates the information that is to be sent over the primary control channel. The scrambling is thus used to encode the information content of the primary control channel into the information of the secondary control channel thereby further protecting the integrity of the information being conveyed over both control channels.
