摘要： The present invention relates to radio base stations including a standardized interface CPRI between a Radio Equipment (RE) and a Radio Equipment Controller (REC). The present invention also relates to a method. The problem addressed is how to convey calibration information from the RE to the REC, when the capacity is occupied by radio IQ samples. The solution is to suppress the IQ samples to get capacity for the calibration information. Various embodiments of the invention focus on reducing the negative impact the suppression of IQ data may have on detecting the signals received.

摘要： A method and base station for forming an OFDM signal from a baseband signal includes a partitioning unit configured to partition a block of baseband signal samples into sub-blocks. A sub-carrier mapper maps the sub-blocks onto adjacent sub-carrier blocks of an OFDM multi-carrier to form corresponding unprefixed OFDM symbols. A cyclic prefix adder adds a cyclic prefix to each mapped sub-block to form prefixed OFDM symbols. Phase compensations force the unprefixed OFDM symbol part of all subsequently up-converted prefixed OFDM symbols to start at the same phase. Up-converters up-convert the phase compensated prefixed OFDM symbols to respective radio frequency bands having center frequencies and bandwidths that preserve the OFDM multi-carrier structure. A combiner combines the up-converted phase compensated prefixed OFDM symbols into an OFDM signal.
摘要翻译：用于从基带信号形成OFDM信号的方法和基站包括：分配单元，被配置为将基带信号样本块分割成子块。子载波映射器将子块映射到OFDM多载波的相邻子载波块，以形成对应的未经修正的OFDM符号。循环前缀加法器向每个映射子块添加循环前缀以形成前缀OFDM符号。相位补偿迫使所有随后上变频的前缀OFDM符号的未经修正的OFDM符号部分在同一相位开始。上变频器将相位补偿的前缀OFDM符号上变频到具有保留OFDM多载波结构的中心频率和带宽的各个无线电频带。组合器将上变频相位补偿的前缀OFDM符号组合成OFDM信号。

摘要： A distributed radio base station (20) comprises a radio equipment controller (REC) (22) situated at a main site (23) and a radio equipment (RE) (24) situated at a remote site (25). A remote unit (102, 104, 106, 108, 110, 124) configured to engage in direct communications with the radio equipment controller (REC) is also situated at the remote site (25). An internal interface (26) connects the radio equipment controller (REC) and the radio equipment (RE). Advantageously, the internal interface (26) also encapsulates the direct communications between the radio equipment controller (REC) (22) and the remote unit, thereby obviating a separate physical link between the radio equipment controller (REC) and the remote unit. A new physical link (130) transmits, between the radio equipment (RE) and the remote unit, the direct communications between the radio equipment controller (REC) and the remote unit which are encapsulated over the internal interface (26). The remote unit can take various differing forms, including that of an antenna (102) with remote electrical tilt control; a tower mounted amplifier (TMA) (104); a Transmission network unit (106); a separate radio base station (108) which is co-located at the remote site; a proprietary equipment unit (110); or even one or more cascaded radio equipments (RE) (124).

摘要： A radio base station (20) has an internal interface (26) which connects a radio equipment (22) and a radio equipment controller (24). At least one and preferably both of the example radio equipment (22) and radio equipment controller (26) comprises a framer (50, 70) which can be controlled for transmitting samples of different protocols over the internal interface. The framer (50, 70) facilitates (1) time multiplexing of N number of frames of a first protocol over the internal interface; (2) inserting L number of samples of a second protocol into M number of the frames of the first protocol, and (3) inserting a padding sample into each frame of the first protocol which does not include a sample of the second protocol. The first protocol has a frame rate; the second protocol has a sample rate which is different from the frame rate of the first protocol, and N is greater than L and M. In any of plural example modes, the padding sample can comprise either of uninterpreted information or information related to the second protocol. For example, the padding sample can comprise a parity value for the L number of samples of the second protocol. In another embodiment and method of operation, in a distributed radio base station a radio equipment controller (REC) sums different carriers and transfers a wide band signal over the internal interface.

摘要： A method and apparatus is described herein for controlling the operating temperature of radio equipment (44, 46) in a radio base station (10) while preventing a decrease in power of a common channel. A radio base station (10) according to the present invention includes a radio unit (40) and a control unit (20). The radio unit (40) determines a temperature of the radio unit (40), e.g., by determining a temperature of high power radio equipment (46) in the radio unit (40). The control unit (20) allocates a desired power to the common channel, determines an available power for dedicated and/or shared channels based on the allocated power for the common channel and a power limit derived from the determined temperature, and allocates the available power to the dedicated and/or shared channels.
