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.

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： 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.

摘要： A rate feedback and adaptation scheme or system uses a rate of rate feedback asymmetrical with the rate of data rate adaptation. In particular, the rate adaptation system provides a rate of rate feedback slower than the rate of rate adaptation. Thus, by allowing the base station to change the data rate more frequently than the individual wireless units reports the rate information, the rate adaptation system can provide improved flexibility and more efficient use of wireless resources while reducing the processing and transmission overhead required to report the rate information. For example, every 3 slots, a wireless unit can calculate and report a rate for the wireless unit to use on a shared channel to send data. The base station receives the rates from the wireless units seeking to send data over the shared channel and selects a wireless unit to use the shared channel. If the base station can adapt the data rate every slot, the base station can adapt the data rate in accordance with a rate reported by another wireless unit, thereby improving system performance. Because of the small slot duration (for example, 0.67 microseconds), the relatively reduced rate of reporting should not adversely effect system performance since it is highly unlikely that the achievable data rate will change over a period of a slot under most operating conditions.

摘要： An uplink and downlink channel structure supports a shared downlink data channel. The new structure accommodates advanced physical and Medium Access Control (MAC) layer techniques, such as incremental redundancy (IR), fast adaptation to channel conditions, and multiple input multiple output (MIMO) antenna configuration. The proposed changes are intended to lead to a downlink structure that achieves higher spectral efficiency for the packet oriented services over then shared downlink channel. Additionally, the new structure uses the base station transmit power information and of the channelization (OVSF) code space more efficiently.

摘要： Disclosed is a method of sub-packet adaptation based on data rate. Specifically, the size of a sub-packet is adapted to a data rate at which the sub-packet is to be transmitted. In one embodiment, the sub-packet is size adapted to the data rate in a format that would allow such size adapted sub-packet to be soft combined with another sub-packet of a same or different size. The size adapted sub-packet may be transmitted prior to or after the other sub-packet.

摘要： Disclosed is a method of data rate adaptation based on channel conditions. In the present invention, data is initially transmitted at a first data rate based on a measured first channel condition and, if a NACK is received, the data is retransmitted. The data retransmitted is at a rate which is based on the condition of the channel during or before the transmission of the NACK. The data retransmission rate can also be based on the actual channel condition at the time of the first transmission plus the condition of the channel before or during the transmission of the NACK.

摘要： A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.

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.
