摘要:
A method, mobile device, network device, system, and software are devised for soft value scaling with a single antenna interference cancellation (SAIC) receiver, or with an interference rejection combining (IRC) receiver, in an unsynchronized network. A signal is received having interference that is caused by a non-synchronized network. A desired power level of that signal is calculated. Then the desired power is compared to a total power of the signal, in order to identify a portion of a received burst having substantial interference. Then that portion of the received burst is weighted, to reduce its importance during decoding.
摘要:
The specification and drawings present a new method, system, apparatus and software product for variable filtering of a mobile station (MS) for supporting uplink communications using available capabilities of a network element in wireless communication systems (e.g., evolved GERAN). The MS may have at least two different pulse shaping filter capabilities providing at least two different bandwidths: one narrower being suitable for legacy transceivers and another wider and thus optimal for variable symbol rate from performance point of view. A BSS (base station subsystem) may then request to use one of those filter capabilities according to BSS available resources
摘要:
A method and corresponding equipment for use by a mobile station and/or a radio access network, for altering one or more characteristics of transmissions of the mobile station to a base transceiver station of the radio access network in respect to power and/or modulation and/or coding of the transmissions, based on monitoring broadcast transmissions from other base transceiver stations of the radio access network and determining an estimate of the likelihood of transmissions by the mobile station interfering with communication between the other base transceiver stations and the mobile stations in communication with those other base transceiver stations.

摘要:
The specification and drawings present a new method, system, apparatus and software product for carrier frequency shifting in mobile communication systems, e.g., for eliminating or reducing interference, e.g., for a communication between a mobile station and a network element. The communication between the mobile station and the network element may be performed within a GSM/EDGE radio access network. A signal (e.g., a DSR or MDSR carrier) and at least one further signal (e.g., a speech carrier) are identified, wherein bandwidths of the signal and of the at least one further signal overlap. Then, a frequency shift for said signal may be determined according to a predetermined criterion and a carrier frequency of the signal may be shifted by the determined frequency shift, e.g., for eliminating or reducing the interference.
摘要:
The specification and drawings present a new method, system, apparatus and software product for using a new modified dual symbol rate (MDSR) in an uplink direction in mobile communication systems. The communication between the mobile station and the network element may be performed within evolved GSM/EDGE radio access networks. The MDSR can be for example one and a half times a symbol rate of an uplink speech service, e.g., the current GSM/EDGE symbol rate (13/48 MHz) in the mobile communication system, thus the MDSR may be substantially 13/32 MHz or about 405 kHz. The uplink signal with the MDSR may be modulated, e.g., using a quadrature amplitude modulation (QAM), e.g., 16-QAM with 16 states and/or a quadrature phase-shift keying (QPSK, or π/4-QPSK) modulation.
摘要:
An indicator of a strength of a signal comprising a training sequence portion received in a radio propagation environment is provided. Samples are taken from the training sequence portion, an energy value of the samples over an estimated channel impulse response is computed and the indicator of the strength of the signal is estimated from the energy value.
