摘要： In an OFDM system, multiple (M) interlaces are defined for M non-overlapping sets of frequency subbands, and M slots with fixed indices are also defined. Data streams and pilot are mapped to slots, which are in turn mapped to interlaces based on a slot-to-interlace mapping scheme that can achieve frequency diversity and good performance for all slots. At a transmitter, a slot-to-interlace converter maps the slots to the interlaces. The slot-to-interlace converter includes multiple multiplexers and a control unit. The multiplexers map the M slots to the M interlaces based on the slot-to-interlace mapping scheme. The control unit generates at least one control signal for the multiplexers. The multiplexers may be arranged and controlled in various manners depending on the slot-to-interlace mapping scheme. At a receiver, a complementary interlace-to-slot converter maps the interlaces to the slots.

摘要： A method for monitoring feedback loop stability in a wireless repeater includes measuring a gain control metric in the feedback loop of the repeater periodically for a given time period where the gain control metric is indicative of a loop gain of the feedback loop of the repeater; and monitoring the magnitude of the gain control metric to determine the stability of the feedback loop of the repeater. In operation, a large magnitude of the gain control metric indicates instability in the feedback loop of the repeater.

摘要： A wireless repeater introduces a low level noise to the signal path of the repeater where the introduced noise is used to facilitate channel estimation. The introduced low power level noise may be added to the receive signal or to the transmit signal. The low power noise signal ensures that the repeater always has a reference signal for performing channel estimation, even when the repeater is not receiving any incoming signal traffic. In one embodiment, a low noise signal is inserted to the transmit circuit of the repeater. In another embodiment, the repeater is configured to increase the noise figure of the receive circuit where the detected noise figure acts as a receive signal.

摘要： In an embodiment, a first repeater configures a beacon signal that identifies the first repeater to one or more other repeaters. The first repeater transmits the configured beacon signal at a given transmission power level to the one or more other repeaters. The transmitted beacon signal is received at least by a second repeater. The second repeater reduces interference associated with other transmissions from the first repeater, such as retransmissions of donor signals, based on the received beacon signal.

摘要： The embodiments utilize OFDM symbols to communicate network IDs. The IDs are encoded into symbols utilizing the network IDs as seeds to scramble respective pilots that are then transmitted by utilizing the symbols. The pilots can be structured into a single OFDM symbol and/or multiple OFDM symbols. The single symbol structure for transmitting the network IDs is independent of the number of network ID bits and minimizes frequency offset and Doppler effects. The multiple symbol structure allows a much coarser timing accuracy to be employed at the expense of transmitting additional symbols. Several embodiments employ a search function to find possible network ID candidates from a transmitted symbol and a selection function to find an optimum candidate from a network ID candidate list.
摘要翻译：这些实施例利用OFDM符号来传送网络ID。 ID被编码成使用网络ID作为种子的符号，以对通过利用符号进行发送的各个导频进行加扰。导频可以被构造成单个OFDM符号和/或多个OFDM符号。用于发送网络ID的单个符号结构与网络ID比特数无关，并且使频偏和多普勒效应最小化。多符号结构允许以牺牲传输附加符号为代价采用更粗糙的定时精度。几个实施例采用搜索功能来从发送的符号和选择功能中找到可能的网络ID候选，以从网络ID候选列表中找到最佳候选。
