Definitions
- the invention relates to a device for generating control signals for a transmission path and control signals for a reception path in a radio station, in particular in a mobile radio station, and a method for generating such control signals.
- Mobile stations that support the UMTS standard have to synchronize their signal processing devices with the signals they receive from base stations. Such synchronization is necessary in order to be able to correctly decode the data obtained with the received signal. Furthermore, a synchronized transmission signal must be sent from the mobile station to the base station so that the base station can correctly decode the transmission signal received from the mobile station.
- UMTS Universal Mobile Telecommunication System
- a signal transmitted by the base station is received by the mobile radio station, the content of this received signal must be analyzed by the mobile station. It is necessary that characteristic signal contents, such as the start of a data transmission frame or the start of a time slot, be recognized. These characteristic signal contents are continuously monitored in order to detect a change in the position of these signal contents, if necessary, and then to be able to track the mobile station. This temporal tracking of the reception path of the mobile station is carried out by means of a control unit in the mobile station. In addition, the mobile station must be synchronized with the times of occurrence of these characteristic signal contents in order to carry out actions at defined times in relation to the received signal. feed, in particular send out signal content.
- the timing of the mobile station to the signals of the base station namely on the one hand tracking the reception path and on the other hand synchronizing the transmission path of the mobile station with the base station, is realized in known arrangements in mobile stations in such a way that for the transmitting station and for the Receive path only a single common sequence control unit is provided.
- only time-continuous signals are generally received and sent. Tracking the mobile radio station to the received signal from a base station and also synchronizing the transmission path therefore pose particular difficulties in the UMTS standard.
- the synchronization of the reception path therefore always requires reprogramming of the control signals of the transmission path. This means that synchronization can only be carried out with a great deal of effort.
- the object of the invention is to provide a device for generating control signals for a reception path and a transmission path of a radio station and a method for generating such control signals, with which or with which the effort of synchronization is minimized.
- a device which has the features of claim 1 and a method which has the features of claim 11.
- a device for generating control signals for a transmission path and control signals for a reception path in a radio station, in particular a mobile radio station, is designed for transmitting / receiving signals of a radio standard with a predetermined time grid.
- An essential idea of the invention is that the device comprises means which are designed such that the control signals of the reception path can be synchronized with reference system information and independently of this the control signals of the transmission path can be synchronized with reference system information.
- the synchronization of the respective control signals to the reference system information takes place independently of one another in time. This makes it possible to synchronize the two paths of the radio station separately from one another.
- the means advantageously comprise a reference unit which is assigned to the circuit branch of the reception path and the circuit branch of the transmission path and with which reference system information is generated for the synchronization of the control signals of the reception path and for the synchronization of the control signals of the transmission path. It can be provided that for the synchronization of the control signals of the reception path a time deviation of the reception system information from the reference system information can be set and / or for the synchronization of the control signals of the transmission path a time deviation of the transmission system information from the reference system information information about the deviation of the transmission system information from the reference system information is stored. It is thereby achieved that the synchronization of the transmission path is carried out in separate system units which are independent of those system units in which the synchronization of the reception path is carried out.
- the reception path and the transmission path separate system units are thus arranged in the device.
- the generation of the control signals, the system information and the deviation of the respective system information from the reference system information is carried out separately for each of the two paths and independently of the other path. Only the reference unit is assigned to both circuit branches - a first circuit branch in which the system units of the reception path are connected and a second circuit branch in which the system units of the transmission path are connected.
- the reference system information includes the frame number of a reference data transmission frame and / or a number of a time slot that is assigned to a reference data transmission frame and / or the number of a unit into which a time slot of a reference data transmission frame is divided. include. It is also advantageous if the reception system information contains the frame number of a reception data transmission frame and / or a number of a time slot which is assigned to a reception data transmission frame and / or the number of a unit into which a time slot of the reception data transmission frame is divided, include. It is also preferred if the
- Transmission system information comprises the frame number of a transmission data transmission frame and / or a number of a time slot which is assigned to a transmission data transmission frame and / or the number of a unit into which a time slot of the transmission data transmission frame is divided.
- the radio standard that the radio station supports is preferably the UMTS standard.
- the radio station is designed to transmit / receive signals of a radio standard with a predetermined time grid.
- An essential idea of the method according to the invention is that the control signals of the reception path are synchronized with reference system information and independently of this the control signals of the transmission path are synchronized with the reference system information.
- An essential advantage of the method according to the invention is that tracking or synchronization can be carried out separately from each other on both paths of the radio station. The necessary reprogramming of the control signals from one of the two paths if the corresponding other path is synchronized, as is inevitable in known methods, is no longer necessary.
- the reference system information is based both on the synchronization of the control signals of the reception path and on the synchronization of the control signals of the transmission path. This enables uniform basic information to be used as the basis for the synchronization of the paths.
- a time deviation of the reception system information generated from the reference system information is advantageously set. Irrespective of this, a time deviation of the generated transmission system information from the reference system information can be set for synchronizing the control signals of the transmission path.
- the setting of the time deviation of the reception system information from the reference System information is programmed independently of the setting of the time deviation of the transmission system information from the reference system information.
- a relative time deviation is preferably set between the reception system information and the transmission system information and an absolute time deviation is set between the reception system information and the reference system information and between the transmission system information and the reference system information.
- the control signals of the reception path are generated in a first control signal unit at precisely the time for reception system information and the control signals of the transmission path are generated in a second control signal unit at the exact time for transmission system information.
- a mobile radio station in particular a mobile radio station, which supports the UMTS standard, has a device for generating control signals for a reception path and control signals for one
- the device comprises a reference unit 1.
- reference system information is stored in memory registers.
- the reference system information which is referred to below as reference time, comprises a frame number of a reference data transmission frame FRAME REF , a number of a time slot SLOT REF , which is assigned to a corresponding reference data transmission frame or into which a reference data transmission frame is divided , and a chip number CHIP REF / into which a time slot of a reference data transmission frame is divided.
- the reference time is the time standard of a mobile radio station and begins to run when the mobile radio station is switched on.
- the reference unit 1 is electrically connected to a first unit 2, the first unit 2 of the reference Unit 1 is connected downstream and 2 reception system information is generated with the first unit.
- the reception system information hereinafter referred to as reception time, comprises a frame number of a reception data transmission frame FRAME RX , a number of a time slot SLOT RX , which is assigned to the corresponding reception data transmission frame or into which a reception data transmission frame is divided, and one Chip number CHIP RX , into which a time slot of the receive data transmission frame is divided.
- the reception time begins to run when a receive data transmission frame FRAME RX and / or a number of a time slot SLOT RX have been recognized.
- the reception time generally begins to run at a time offset from the reference time.
- the reference unit 1 is electrically connected to a second unit 3, the second unit 3 being connected downstream of the reference unit 1.
- transmission system information is generated independently of the reception system information in the first unit 2.
- the transmission system information hereinafter referred to as transmission time, comprises a frame number of a transmission data transmission frame FRAME TX , a number of a time slot SLOT ⁇ x , which is assigned to the transmission data transmission frame, and a number of a unit CHIP T ⁇ into which a time slot of the transmitting data transmission frame is divided.
- a first storage unit 4 is electrically connected to the first unit 2.
- a time deviation of the reception time from the reference time is programmed or stored in the first memory unit 4.
- a frame number of a receive data transmission frame FRAME RX a number of a time slot SLOT RX , which is assigned to the receive data transmission frame, and a number of a unit CHIP RX , into which a time slot of the receive data transmission frame, are entered as information is divided.
- a second storage unit 5 is electrically connected to the second unit 3.
- a time deviation of the transmission time from the reference time is programmed or stored in the second memory unit 5.
- a frame number of a transmission data transmission frame FRAME TX , a number of a time slot SLOT ⁇ x , which is assigned to the transmission data transmission frame, and a number of a unit CHIP TX , into which a time slot of the transmission data transmission frame, are used as information is divided.
- the time deviations of the reception time and the transmission time from the reference time are specified in particular in numbers of a unit CHIP RX or CHIP ⁇ , into which a corresponding time slot of a corresponding data transmission frame is divided. Furthermore, the time deviations of the reception time from the reference time can be programmed independently of the time deviations of the transmission time from the reference time in the first memory unit 4 or in the second memory unit 5. Due to the flexible programming options for reception and transmission processes - given by the independent units 2 and 3 - the time interval required by the UMTS standard between the reception time and the transmission time (1024 chips with a tolerance of 1.5 chips) can be used as an offset Reference time can be set. In addition, it is possible to achieve filter runtimes in the transmission path by changing the time deviation from transmission time to reference time by simply reprogramming a counter offset without having to reprogram a possibly very extensive sequence of control signals on the reception path.
- the first unit 2 is electrically connected to a first control signal unit 6 connected downstream of this first unit 2.
- Control signals of the reception path are generated by means of the first control signal unit 6.
- the control signals generated in the first control signal unit 6 for the reception Paths are thus shifted in absolute time relative to the reference system information with the time deviation programmed in the memory unit 4.
- the control signals are thus generated precisely at specific reception times for the reception path.
- the second unit 3 is electrically connected to a second control signal unit 7 connected downstream of this second unit 3.
- control signals of the transmission path are generated independently of the control signals of the reception path.
- the control signals for the transmission path generated in the second control signal unit 7 are thus shifted in absolute time relative to the reference time with the time deviation programmed in the second memory unit 5.
- the control signals of the transmission path are thus generated at precise transmission times for the transmission path.
- the reception time has a relative time shift to the transmission time.
- the reception time as well as the transmission time each show an absolute time shift.
- the tracking and synchronization of the reception path and the transmission path can be carried out independently of one another. At the same time, however, it is ensured that this tracking or synchronization of the receive and transmit path meets and maintains the relative temporal shift of 1024 chips between the receive path and the transmit path required by the UMTS standard with a tolerance of 1.5 chips. In addition, it is made possible that both the reception time and the transmission time can be shifted in absolute terms relative to the reference time. Due to the possibility of independent Programming of the receive and transmit operations, due to the two temporally independent units 2 and 3 for generating the reception time and the transmission time, a ⁇ we sentlich greater flexibility can be achieved.
