摘要:
A method provided by the present invention for transmitting overhead information, includes dividing and reforming to-be-transmitted overhead information into at least two overhead parts; inserting the at least two divided overhead parts into overhead bytes of at least two corresponding data frames successively, wherein the at least two divided overhead parts corresponds to the overhead bytes and transmitting via the at least two data frames. Overhead information transmitting apparatus and overhead information receiving apparatus are also provided by the present invention. With the method and apparatus of the present invention, the channel bandwidth resources occupied by the overhead bytes of each microwave frame are greatly reduced. If the saved channel bandwidth is used for performing the error correction code on the transmitted information, the code gain is improved and the sensitivity requirement on the receiver is reduced so that the cost of a microwave transmitting system is reduced eventually.

In the method, a current channel condition is estimated based at least in part on a previous channel quality indicator and power control information received after the previous channel quality indicator.
摘要:
A method for transmitting a frame comprised of a plurality of slots over a dedicated control channel in a duration where there is no transmission message from a mobile station to a base station. Each slot in the frame is comprised of a first slot duration and a second slot duration. The first slot duration is provided with a power control signal and the second slot duration is provided with no signal at a partial duration thereof.
摘要:
Techniques for transmitting data in a manner to facilitate equalization at a receiver are described. Guard intervals are appended to data blocks such that each data block has a guard interval at the beginning of the data block and a guard interval at the end of the data block. Each guard interval may be discontinuous transmission (DTX), a polyphase sequence, or some other known sequence. Pilot is appended to each set of at least one data block. The data blocks, pilot, and guard intervals may be sent using various slot structures and are processed for transmission. The processing may include mapping the data blocks to at least one physical channel, channelizing the data blocks for each physical channel with a channelization code, combining all physical channels, and scrambling the combined data, pilot, and guard intervals with a scrambling code.

A control for varying a maximum transmission power of a transmitter according to a distance between a base station and a mobile station can reduce deterioration of a user capacity to a minimum. In the mobile station (316), a distance from the mobile station (316) to a base station is estimated (S701). The estimated distance information is transmitted to be based station (S702). The base station decides a maximum transmission power of transmission signal transmitted from the mobile station (316) on the basis of the distance information received (S703). The decided maximum transmission power information is transmitted to be mobile station (316) (S704). The mobile station (316) designates a maximum amplification amount to the transmission amplifier (304) for amplifying the transmission signal on the basis of the maximum transmission power information transmitted from the base station (S705).

High speed data packet access (HSDPA) is facilitated by ensuring that power offsets are delivered to the base station (Node B) so that the new functions envisioned therefor having to do with scheduling and retransmission handling can be carried out effectively. A signal primitive having one or more information elements indicative of corresponding power offsets are received by the Node B, saved for future use and then signalled back to the serving radio network controller so that the user equipment can be informed with a proper RRC message containing the appropriate power offsets.
摘要:
A method for controlling the function of a mobile station (MS) in a packet switched communication network based on a cellular network, which communication network is arranged to transfer information between a base station (BTS) and at least one mobile station (MS) by means of a radio channel, wherein to transfer information, a transmission power of a set level is used on the radio channel, wherein information that is divided Into successive blocks is transmitted from the base station to the mobile station via a radio channel, characterized in that a block that is transmitted repeatedly and at fixed intervals is transmitted with a fixed transmission power in order to establish a reference level,

A method is disclosed for determining by a UTRAN a persistence value having a value between 0 and 1 for adjusting a number of access preambles from a plurality of UEs requiring assignment of a common packet channel (CPCH). The method includes the steps of counting a number of the access preambles detected in an access preamble period having a predetermined period; and determining the persistence value based on the number of counted access preambles. The persistence value is determined in a unit of transport format (TF), physical common packet channel (PCPCH), or CPCH set.
摘要:
A mobile wireless communication system including a wireless communication apparatus and a counterpart wireless communication apparatus is provided, the system establishing wireless communication between the wireless communication apparatus and the counterpart wireless communication apparatus by multiplexing (3, 44) plural channels including at least a traffic channel (TCH) for transmitting a packet, a control channel (CCH) for transmitting control information for receiving the packet, and a channel (DCH) for transmitting information including transmission power control information. The wireless communication apparatus includes a transmission unit (1) that transmits the transmission control information to the counterpart wireless communication apparatus via the channel for transmitting information including transmission power control information at intervals of a prescribed period that is longer than a length of the packet, and transmits the transmission power control information via the control channel when the packet is being transmitted via the traffic channel.
摘要:
Disclosed is a method for indicating an end of transmitting data frames in order to enable a UTRAN (UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network) to assign a common packet channel to another user equipment (UE) in a UE for a CDMA mobile communication system. The UE transmits at least one control frame, in an appointed field of which a given bit pattern appointed with the UTRAN is registered, in order to inform the UTRAN of an end of data transmission upon completing data transmission through the data frames.
