In a radio communication system, a first network-based radio station transmits information destined for a plurality of subscriber stations. A second network-based radio station transmits messages destined for individual subscriber stations and the second network-based radio station receives by radio the information transmitted by the first network-based radio station and transmits the same.

In a radio communications system, several codes for transmitting messages are assigned to a subscriber station. A transmission power differential is determined between the total maximum transmission power of the subscriber station for the codes and the total transmission power of the subscriber station for the codes at the beginning of a message transmission, (the differential being respected by the subscriber station), by a first one of the codes.

A method performs measurements by a mobile station of a radio communication system. According to said method, the mobile station receives data via a first channel. Said mobile station temporarily interrupts the reception of the data, in order to perform measurements on at least one second channel. The interruption of the reception takes place according to a correctability of errors occurring during the data transmission via the first channel.

In a wireless communication system, signals within a connection on a wireless interface are transmitted exclusively in a packet-switched manner between a user station and an access device located on the network. The user station signals a need to measure signals to the access device, the access device sends measurement signaling to the user station, and the user station measures signals of at least one additional access device located on the network at a second frequency range while receiving data packets within the connection at a first frequency range based on the received measurement signaling, the second frequency range being disjunct from the first frequency range.

The invention relates to a method of detecting a jamming transmitter affecting a communication user equipment, wherein said communication user equipment (UE) and a number of base node stations (BNS) are components of a cellular code division multiple access (CDMA) based radio network (RN), wherein a communication signal unit (SU) is correlated with a pseudonoise spread code (SC) in a serving cell coverage area (CA) of a serving base node station (sBNS) and transmitted as a pseudonoise chip (CHI) in a multiple shared communication frequency channel spectrally located between an upper frequency and a lower frequency of a communication frequency band (FB I-XIX) and the pseudonoise spread code (SC) is received by the communication user equipment (UE) as a serving pseudonoise spread code (sSC) from said serving base node station (BNS) in a serving downlink channel (sCPICH).
摘要:
To distinguish between stationary and free-to-move terminal devices in a mobile communication network in order to reduce paging interference, a stationary terminal device chooses a surrounding radio cell as a home cell, which remains associated to the stationary terminal device, as long as the home cell fulfils a suitable-cell-requirement. Therefore, the communication network can be operated such that a paging request is only distributed through one base station/NodeB, if that paging request is to be forwarded to a stationary terminal device being associated to a home cell. According to another aspect of the present invention, stationary terminal devices are grouped in separate paging group that is stored in an operation unit of the mobile communication network. If a paging request is to be distributed, it is firstly checked, whether the paging request is to be forwarded to one of the terminal devices of the separate paging group.
摘要:
A method operates a radio communication system in which network radio devices use radio resources in order to communicate with subscriber stations. A first network radio device performs direct tuning with a second network radio device using the respectively used radio resources. The first and/or the second network radio device send(s) a request for a decision about radio resources to be used by the first and/or the second network radio device to a device. Subsequent to the request, the first and/or the second network radio device receive(s) information from the device about radio resources to be used by the first and/or the second network radio device. A radio communication system carries out the method.
摘要:
A method of controlling receipt of signals at a terminal (1) of communications system involves receiving data (D1,D2) on at least one control channel from a first base station (2). The terminal is adapted to periodically perform measurements on signals transmitted by at least one second base station (3,4). The terminal determines whether a period in which data signals (D2) are on the at least on control channel at least partially overlaps with a period for performing measurements (M2) and disables performance of measurements in favor of receipt of data on the at least one control channel.
摘要:
A communication system having a plurality of common channels and includes a primary common control physical channel, a plurality of dedicated channels and a synchronization channel (SCH). The primary common control physical channel and the synchronization channel are transmitted time multiplexed, and the sum transmit power of dedicated channels is reduced during the transmission of the synchronization channel in order to keep the total output power at the base station power amplifier below a maximum power limit.
摘要:
In a method for communication by radio a first network radio station allocates radio resources to a subscriber station and communicates with the subscriber station using a portion of the radio resources. A second network radio station uses another portion of the radio resources to send a signaling signal which is intended exclusively for the subscriber station. The first network radio station and/or the second network radio station receives a message from the subscriber station, acknowledging receipt of the signaling signal. In response to the message from the subscriber station, the communication of the subscriber station is handed over from the first network radio station to the second network radio station.
