A receiver receives a data packet with a header and a payload. The payload includes at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment, where a service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. The header includes a single field consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. Digital signal processing circuitry processes the header to determine processing for the payload.

Method and apparatus for receiving data packets

A data packet comprises a header and a payload. At least one digital signal processor is used to configure the payload to transport at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment. A service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. At least one digital signal processor is used to configure a single field in the header consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. At least one digital signal processor is used to form the data packet including the configured header and the configured payload. A transmitter transmits the data packet.

Method and apparatus for transmitting data packets and method and apparatus for receiving data packets

A data packet has a header and a radio link control (RLC) protocol data unit (PDU). The RLC PDU transports at least one full RLC service data unit (SDU), one or two RLC SDU fragments, or at least one full RLC SDU and at least one RLC SDU fragment. An RLC SDU fragment is only located (i) at the beginning or end of the RLC PDU or at the end of the radio link control protocol data or (ii) at the beginning and end of the RLC PDU. A single field in the header consists of a first bit and a second bit, even when a number of full RLC SDUs and RLC SDU fragments in the RLC PDU is more than two. The single field indicates whether (i) the RLC PDU begins with a fragment of a RLC SDU and (ii) the RLC PDU ends with a RLC SDU fragment. The data packet is formed including the configured header and the configured RLC PDU and transmitted.

A data packet structure conveys data of service data units (SDU) using protocol data units (PDU). The data packet structure includes a data packet payload having at least one protocol data unit (PDU). A protocol data unit (PDU) includes a service data unit (SDU) or a fragment of a service data unit and a data packet header including an indicator indicating whether or not the data packet payload begins with a protocol data unit (PDU) being a fragment of a service data unit and whether or not the data packet payload ends with a protocol data unit (PDU) being a fragment of a service data unit.

The invention relates to a data packet structure for conveying data of service data units (SDU) using protocol data units (PDU). The data packet comprise a data packet payload comprising at least one protocol data unit (PDU), wherein a protocol data unit (PDU) comprises a service data unit (SDU) or a fragment of a service data unit; and a data packet header comprising an indicator (FFF,SFF) indicating whether or not the data packet payload begins with a protocol data unit (PDU) being a fragment of a service data unit and whether or not the data packet payload ends with a protocol data unit (PDU) being a fragment of a service data unit.

In a mobile terminal of a wireless communication system, such as UMTS or any future communication system, the actual reception quality of data received on a broadcast channel, such as BCCH or MTCH, is measured. Based on the measurement result, a report is prepared and sent to a radio network controller, which controls the transmission on the broadcast channel. The report does not contain the identifier of the mobile terminal. Therefore the reporting can be accomplished without informing the radio network controller about the identity of the mobile terminal.

Anonymous uplink measurement report in a wireless communication system

The invention relates to a data packet structure for conveying data of service data units (SDU) using protocol data units (PDU). The data packet comprise a data packet payload comprising at least one protocol data unit (PDU), wherein a protocol data unit (PDU) comprises a service data unit (SDU) or a fragment of a service data unit; and a data packet header comprising an indicator (FFF, SFF) indicating whether or not the data packet payload begins with a protocol data unit (PDU) being a fragment of a service data unit and whether or not the data packet payload ends with a protocol data unit (PDU) being a fragment of a service data unit.

Method and apparatus for packet segmentation and concatenation signaling in a communication system

The present invention relates to a method for configuring an acknowledgement mode of an HARQ re-transmission protocol used for acknowledging the delivery of data packets of a service provided from a transmitting entity to a receiving entity in a wireless communication system comprising a controlling entity in a radio access network. To improve the overall transmission efficiency while providing transmission robustness, the controlling entity configures, based on at least one of a QoS attribute or physical layer parameter, one of a first and second acknowledgement mode. An acknowledgement message is transmitted according to the configured acknowledgement mode, wherein, in case the data packet has not been decoded successfully by the receiving entity, the acknowledgement message in the first acknowledgement mode indicates one of a plurality of decoding quality levels of the data packet obtained when decoding the data packet at the receiving entity, and the acknowledgement message in the second acknowledgement mode indicates a decoding failure of the data packet.

Configurable acknowledgement mode for a hybrid automatic repeat request protocol

The invention relates to a method for providing measurements on a bit-rate provided to scheduled data having a guaranteed bit-rate and being transmitted on at least one dedicated uplink data channel by at least user equipment via a C-RNC. Further, the invention also relates to a method for initiating congestion control for scheduled data of at least one guaranteed bit-rate priority class in a mobile communication system. Moreover, the invention relates to a C-RNC as well as a serving radio network controller performing these methods. To enable the C-RNC within a mobile communication system to perform congestion control for uplink transmissions having a guaranteed bit-rate the invention suggests to provide the C-RNC with a bit-rate being provided to scheduled data of the guaranteed bit-rate priority class using common or dedicated measurement procedures. This provided bit-rate is evaluated and taken as a basis for deciding on whether congestion control for data of the priority class needs to be performed.

Support of guaranteed bit-rate traffic for uplink transmissions

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.
