    摘要： Information is coded and segmented into a plurality of sub-packets. Each sub-packet contains identification information and a one-bit information status flag indicating whether the information is ‘new’ information or ‘continue’ information. The information to be transmitted is then applied to a scheduling algorithm that determines when the information is to be transmitted, how much information is to be transmitted and how many attempts at a successful transmission of the information is allowed. In this manner, the transmission of information can be performed in an asynchronous manner.

    摘要： 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 is described for transmitting information in a communication channel of a wireless communication system in which the communication channel is divided into a plurality of time slots of equal duration and each of the time slots is further sub-divided into multiple sub-slots or resource units. In one illustrative embodiment, the communication channel is divided into time slots according to a time division multiple access scheme. Each time slot is then further code-multiplexed into one or more sub-slots according to a code division multiple access scheme. Each of the sub-slots is therefore capable of carrying a separately coded transmission within the communication channel so that multiple simultaneous transmissions can occur in any given time slot.

    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.

    摘要： A method for transmitting control information in a wireless communication network is provided in which one or more prescribed fields in an existing control channel structure are modified to enable express signaling directly between a base station and at least one mobile station without the need to traverse a backhaul path between the base station and the base station controller. More specifically, prescribed fields in the control channel are modified to carry one or more prescribed message identifiers that convey different types of information, e.g., an identifier for indicating which mobile station is the intended recipient, an identifier for indicating the type of message being transmitted (e.g., broadcast, multicast, etc.), a message identifier indicating the available Walsh space for data transmission, and so on. In this manner, existing control channel structures and formats can accommodate many different signaling functions directed to either single or multiple mobile stations.
