摘要： A method and arrangement (300) for noise variance and SIR estimation in a UTRAN Node B (122) or User Equipment (118) estimates the SIR at the output of a detector (310) by using an estimate of the detector input noise variance to provide an estimate of the detector output noise variance. The detector input noise variance is derived from a midamble portion (220) in the received signal. By deriving the transfer function of the detector an estimate of the detector output noise variance is estimated. The estimated output noise variance then allows an improved estimate of the SIR at the detected output.

摘要： A system, transmitter, receiver and method for communication power control by the transmitting entity (150A) keeping a sequence number counter (200) per UE (130A) that is incremented whenever a common channel transmission is made specifically to that UE. The value of the counter is signalled inside the message itself (or possibly by other signalling means) across the Uu interface. When the intended recipient UE correctly decodes a message, it also decodes the counter value. It compares this counter value with the last correctly received sequence number, which it holds in a memory (300), and deduces whether there are any missing sequence numbers, and accordingly effects transmission power control

摘要： Automatic gain control (AGC) and synchronisation acquisition by a communication unit in a wireless communication system, e.g. a Universal Mobile Telecommunication System (UMTS) system, is described. AGC is performed using a downlink beacon function, for example a power level (P beacon ). Amplitude-equalising (limiting) is performed as part of synchronisation acquisition. Separate AGC processes are used for different stages of synchronisation acquisition. One AGC process uses a peak power (P (k)) of a received signal over a frame. Another AGC process uses a peak power (P (k)) of a received signal over only a portion of a frame, the portion comprising an initial synchronisation code. Another AGC process uses measurements of a received signal (P 0 (k)) taken in a downlink beacon timeslot. These processes tend to provide tolerance to a varying number of codes (M) transmitted on a timeslot-by-timeslot basis and robust initial synchronisation in the presence of strong uplink interference.
摘要翻译：无线通信系统中的通信单元的自动增益控制（AGC）和同步采集，例如，描述了通用移动电信系统（UMTS）系统。使用下行链路信标功能（例如功率电平（Pbeacon））来执行AGC。幅度均衡（限制）作为同步采集的一部分进行。单独的AGC过程用于不同阶段的同步采集。一个AGC过程使用帧上的接收信号的峰值功率（P（k））。另一AGC过程使用仅在帧的一部分上的接收信号的峰值功率（P（k）），该部分包括初始同步码。另一个AGC过程使用在下行链路信标时隙中采用的接收信号（P0（k））的测量。这些过程倾向于在存在强上行链路干扰的情况下，在逐个时隙基础上传输的不同数量的码（M）和鲁棒的初始同步提供容限。

摘要： An apparatus (300) for a cellular communication system (100) comprises a buffer (303) which receives data for transmission over an air interface (115). The buffer (303) is coupled to a scheduler (305) which schedules the data and allocates the physical resource of the air interface (115). The transmissions are performed using a retransmission scheme such as a Hybrid-Automatic Repeat reQuest scheme. A load processor (309) determines a load characteristic associated with the scheduler (305) and a target controller (311) sets a target parameter for the retransmission scheme in response to the load characteristic. Specifically, a block error rate target may be set in response to a load level of a cell or plurality of cells. A transmission controller (307) sets a transmission parameter for a transmission in response to the target parameter and a transmitter (301) transmits the data using the transmission parameter. Accordingly, an operating point of the retransmission scheme may be dynamically adjusted thereby reducing overall latency.

摘要： Embodiments of the invention provide a controller, in a cellular wireless network for cancellation of interference from neighboring cells. Logic in the controller determines channel quality of a radio channel between a first base station and a UE. Scheduling logic causes the first base station to adjust a number of data streams used for communication with the UE and a second base station to adjust a number of data streams used for communication to a second UE within a time period, as a function of the channel quality. Other embodiments provide an apparatus for reducing interference in a receiver that receives N data streams. Signal processing logic receives the N data streams, where N-M of the data streams represent interference with respect to M desired data streams, and cancels the N-M data streams so as to receive the M desired data streams. The N data streams may be received from multiple base stations, or multiple UEs.

摘要： Embodiments of the present invention distinguish a first type of data packet transmitted over a random access communication channel of a wireless cellular communications system from a second type of data packet transmitted over the same random access communication channel, allowing the first and second data packet data packet types to share a common set of rando m access channels through the use of different types of channel coding. This reduces data packet collision probability by eliminating the need to segregate the set of random access channels according to data packet type. Backward compatibility with legacy base stations that handle only the first data packet type is maintained in that no changes to the first data packet type are needed.
