Abstract: A traffic load can be determined in a telecommunications system using narrowband signal monitoring. Narrowband signals can be generated from a wideband uplink signal. A resource utilization profile can be estimated for a remote unit based on measured power profiles associated with the narrowband signals. Traffic load can be determined based on the resource utilization profile.

Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

Abstract: Certain features relate to compensating for a roundtrip delay caused by a distributed antenna system. A delay unit communicatively coupled to a base station can intercept the delay compensation signaling communicated between the digital baseband unit of the base station and the radio transmitter unit of the base station. The delay unit can adjust the delay compensation signaling by adding to the delay compensation signaling the pre-determined fiber delay caused by the DAS. In some aspects, the delay unit can delay the control words for a base station operating under the Common Public Radio Interface standard. In other aspects, the delay unit can delay the round-trip time measurement message for a base station operating under the Open Base Station Architecture Initiative standard.

Abstract: A radio frequency transmitter device, constituted for transmitting a radio frequency signal in a frequency band comprising at least one transmit subband and at least one receive subband, comprises: a transmit chain for processing a transmit signal associated with the at least one transmit subband; a power amplifier for amplifying the transmit signal; an output port for transmitting the amplified transmit signal; a processing unit for calculating, from the transmit signal associated with the at least one transmit subband, a correction signal in the at least one receive subband making use of a power amplifier model modelling the behavior of the power amplifier; and a coupler for adding the correction signal to the amplified transmit signal for cancelling intermodulation products in the amplified transmit signal produced by the power amplifier.

Abstract: A multistage combining sub-system for a distributed antenna system (“DAS”) is disclosed. The combining sub-system can receive broadband uplink signals from remote units of the DAS. The sub-system can divide the received broadband uplink signals into sets of narrowband uplink signals. The combining sub-system can select subsets of narrowband uplink signals from the sets of narrowband uplink signals. The subsets can be selected based on the narrowband signals in the subsets having a signal characteristic indicative of useful information. The combining sub-system can combine the selected subsets of narrowband uplink signals for routing to a base station. Combining the selected subsets of narrowband uplink signals can involve excluding narrowband uplink signals that are not included in the selected subsets of narrowband uplink signals.

Abstract: The present disclosure describes devices, systems, and methods for allocating bandwidth among communication links in a telecommunication system. Some aspects can involve identifying multiple transmission modes used to transmit downlink signals via remote units of a telecommunications system to groups of terminal devices. Each group of terminal devices may receive downlink signals using a respective transmission mode. Respective weights can be assigned to the groups of terminal devices based on the transmission modes. The downlink signals, which are provided to each remote unit associate with each group of terminal devices, can be configured using a respective signal power that is associated with a respective weight for the group of terminal devices associated with the respective remote unit.

Abstract: A digital repeater system for repeating RF signals comprises: a receiving section for receiving an RF input signal, the RF input signal comprising at least one frequency band including a multiplicity of subbands associated with a multiplicity of communication channels; and at least one transmitting section for transmitting the RF output signal. The receiving section is constituted to digitize the RF input signal to obtain a digital input signal and to isolate, within the digital input signal, the multiplicity of subbands from each other to obtain a multiplicity of digital subband signals. The at least one transmitting section is constituted to combine the digital subband signals to obtain a digital output signal and to convert the digital output signal to an RF output signal. In addition, the receiving section comprises a power profile estimation unit for determining a power estimate for each digital subband signal associated with the multiplicity of subbands and a muting device for muting a digital subband signal of a particular subband based on the power estimate. In this way a digital repeater system for repeating RF signals is provided which allows for a detection of unused portions of a frequency band in order to improve the performance of the overall system.
