摘要:
In a wireless communication system, there is a method of generating and transmitting signaling information from a user, where user control information may be appended as a header to a data block, and the data block and header may be encoded and transmitted as a signaling message from the user. In a method of scheduling a user for transmitting information, a signaling message, which may include user control information, is received from a user. A scheduling grant message that may include an allocated data rate may be transmitted in response to the received signaling message. The user control information may include one or more of buffer status information of the user, reverse pilot channel transmit power information and data related to a soft handoff (SHO) status of the user.

In the method, information from a user is transmitted over one or more communication channels of a wireless communication system by code multiplexing transmissions in the code domain. The method may include code multiplexing a first information from the user over a first channel with a second information from the user over a second channel, and determining a transmission format for the first and second channels. The transmission format may be determined based on one or more of available transmit power, transmission time interval, a coding dimension used for multiplexing, and transmit power used per code. The first information and second information are transmitted over the respective channels based on the determined transmission format.
摘要:
In a wireless communication system, there is a method of transmitting over a reverse link, where a medium access control layer multiplexes data from upper level layers onto transport channels that are used based on whether the user is in a scheduled transmission mode or an autonomous transmission mode. The transport channels may be mapped to one or more physical channels associated with a particular transport channel, based on whether the transport channel is dedicated for use in the scheduled or autonomous mode.

摘要:
A method that globally allocates resources of a communication system. A global fast scheduler receives global CQI information from UEs of a communication system. The global fast scheduler determines a resource allocation value and assigns a UE to any available cell site that is a member of the active set of the UE and which can service the UE in accordance with the determined resource allocation value.

The performance of closed loop transmit diversity (CLTD) systems may be improved, in accordance with aspects of the present invention, by encoding antenna control information fed back from a mobile station to a base station. As compared to prior art CLTD systems that send antenna control bits in unencoded feedback messages, encoding the antenna control information may result in reduced feedback delays and reduced transmission power. Further, in accordance with some aspects of the present invention, the antenna control bits may be fed back to the base station on a common feedback channel also used to feed back channel quality indication, thus reducing processing overhead.

摘要:
A method for processing control information in a wireless communications system is described in which portions of the control information are separately encoded and decoded such that transmission format information for a corresponding data transmission can be determined with a reduced set of decoded control information. The control information is convolutionally coded using either a single set of tail bits or by judiciously dispersing the tail bits among different portions of the encoded signaling information.
摘要:
A composite signaling message part is formed to include at least two segments, each segment including data identifying a different user equipment (UE). The part further includes a cyclic redundancy code (CRC) generated by jointly encoding the at least two segments. In a further aspect of the method, more than one shared control channel jointly carrying a signaling message are power controlled such that each shared control channel carrying more data associated with one of the UEs is power controlled in accordance with that UE.
