摘要： A method for rate selection by a communication device for enhanced uplink during soft handoff in a wireless communication system includes a first step of receiving information from a scheduler. This information can include one or more of scheduling, a rate limit, a power margin limit, and a persistence. A next step includes determining a data rate for an enhanced uplink during soft handoff using the information. A next step includes transmitting to a serving base station on an enhanced uplink channel at the data rate determined from the determining step.

摘要： A method for adjusting an OLT for power control, which is capable of closely tracking a low tFER. The OLT is adjusted based on frame quality indicator FQI and channel quality metrics. FQI and channel quality metrics are generated at the receiver of a base transceiver station after reception of a frame. If FQI equal to a logic zero was generated, the OLT is adjusted upwards using a first stepsize. If FQI equal to a logic one was generated for a certain amount of consecutive frames, the OLT is adjusted downwards using a second stepsize. The OLT is also fine-tuned during the intervals between the transitions caused by applying the first stepsize or second stepsize. The first and second stepsizes and the amount of consecutive frames of FQI=1 before OLT is adjusted downwards are determined adaptively according to time-varying channel conditions and received frame quality indicator.
摘要翻译：一种用于调整用于功率控制的OLT的方法，其能够紧密跟踪低tFER。基于帧质量指标FQI和信道质量度量来调整OLT。 FQI和信道质量度量在接收到帧之后在基站的接收机处产生。如果产生等于逻辑零的FQI，则使用第一步骤向上调整OLT。如果对于一定量的连续帧产生等于逻辑1的FQI，则使用第二步骤来向下调整OLT。在通过应用第一步骤或第二步骤引起的转换之间的间隔期间，OLT也被微调。根据时变信道条件和接收到的帧质量指标，自适应地确定在OLT下调节之前的第一和第二步长并且FQI = 1的连续帧的量。

摘要： Separate forward dedicated and shared control channels are provided in a spread-spectrum communication. The forward dedicated control channel is used to communicate persistent control information and point to the shared control channel when further intermittent control information concerning transmission of data to a mobile station needs to be communicated. The use of a dedicated control channel for only necessary persistent control information, while only pointing to a shared control channel when it is needed, affords more efficient utilization of system resources.

摘要： A wireless system includes base station transceivers (102-104) to communicate with at least one mobile station (108), the base station transceivers communicate with a network controller (110). The base station controls a header for a packet frame to be communicated between the base station transceiver and the network controller wherein a portion of the header identifies the frame as one containing no data package. The data bits of the header field may contain a predetermined bit pattern for a frame including no data package. Information received by the base station from the mobile station may be dropped, and the header information replaced with the specified bit pattern, if a decoding metric passes a threshold. The information received by the base station from the mobile station may be dropped, and the header information replaced with the specified bit pattern, if a CRC for the frame received from the mobile station fails.

摘要： A method and system for retransmitting data packets in a communication system having variable data rates is disclosed. In a preferred embodiment, data packets are packetized to an atomic packet size equal to that of a lowest rate packet. If a data packet requires retransmission at a rate different than that at which the data packet was initially transmitted, the rate is dynamically changed based upon a multiple of the atomic packet size.

摘要： A high-speed data channel (105) is set to some minimum power level and changed to a second power level after at least one good frame has been received on a reverse link dedicated control channel (DCCH). The forward data channel power level (after a good reverse link frame is received on the DCCH) is increased over a plurality of frames to a power level that differs from the forward DCCH (103) power level, and is based on a difference in the number of handoff links between the DCCH (103) and the high-speed channel (105). Power control of the data channel (105) (after achieving the second power level) is then additionally based on a time between repeats sent due to negative acknowledgments of packet data frames sent on the data channel (105).
摘要翻译：在反向链路专用控制信道（DCCH）上接收到至少一个好的帧之后，将高速数据信道（105）设置为一些最小功率电平并变为第二功率电平。正向数据信道功率电平（在DCCH上接收好的反向链路帧之后）在多个帧上增加到与前向DCCH（103）功率电平不同的功率电平，并且基于 DCCH（103）和高速信道（105）之间的切换链路的数量。数据信道（105）的功率控制（在实现第二功率电平之后）另外基于由于在数据信道（105）上发送的分组数据帧的否定确认而发送的重复之间的时间。

摘要： A communication system provides for adaptive rank determination, for example, a rank 2 transmission in instances where a rank 1 transmission may be indicated under supported feedback modes in current standards where no explicit power adaptation can be assumed, for example, where a user equipment (UE) is limited to reporting a rank 1 channel due to a large dynamic range of a signal or due to a signal received by the UE from one base station (BS) antenna port drowning out a signal received by the UE from another BS antenna port. The communication system provides for the UE to implement rank 2 transmission in such instances by using per-antenna port power control at a BS serving the UE. In one embodiment, the BS controls the rank determination at the UE by signaling transmit power or power offset related parameters to use for rank and transmission parameters determination and feedback.

摘要： A communication system is provided wherein a user equipment (UE) receives control information from a wireless network. The UE monitors control channel candidates using common reference signals (CRS) and monitors enhanced control channel candidates using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode, such as transmission mode 9, for receiving a downlink shared traffic channel based on DMRS. The UE monitors control channel candidates only using CRS when the UE is configured in a second transmission mode, such as any of transmission modes 1-6, for receiving a downlink shared traffic channel based on CRS. The UE then receives downlink control information (DCI) in a subframe in one of the monitored control channel candidates or enhanced control channel candidates in the subframe.
