摘要： Real-time media or multimedia services in 3GPP GSM/EDGE-compliant mobile radio networks call for reducing the actual latency of transmissions. Resources are assigned by the network to set up or reconfigure a TBF associated to the uplink/downlink transmission of radio blocks from/to an MS. A 5-bit "Coding" field is configured in the header of the involved RLC/MAC messages to select the transmitting/receiving window size. An additional signalling bit, also called scaling bit, is asserted/negated according to two opportunities offered by the new MAC protocol to properly select the window size. Thanks to the introduction of the scaling bit a subdivision of the time windows for type of services is made possible. Non real-time services, e.g. file transfer, avail of standard window sizes for MSs with multistat capability, as reported in 3GPP TS 44.060, V7.3.0 (2006-01 ), Release 7, subclause 9.1.9, for EGPRS TBFs. Delay-sensitive services, e.g. media or multimedia real-time transmissions, avail of new window sizes with scaled down values remapped to start from 1 to (maximum) 64 RLC/MAC blocks. The scaling bit is asserted or negated by BSC accordingly. Both peer entities comprised in a TBF are receiving the RLC/MAC messages with the proper setting of the scaling bit and the 5-bit coding IF; these entities decode the scaling bit and behave accordingly. The behaviour consists of either assuming the standard window size or scaled window size addressed by the same predetermined 5-bit "coding" information element.

摘要： The invention concerns an improvement to the most recent proposals about a fast ARQ mechanism to be operated soon inside 3GPP GERAN mobile radio systems. The fast ARQ avails of short bitmaps, spanning only few octets, piggybacked in the payload of the RLC/MAC block which conveys the relevant ACK/NACK signalling. The main improvement is that to shift the short bitmap from payload data to the header of the same RLC/MAC block transmitted either in uplink or downlink direction, indifferently. This allows the short bitmap to be encoded together with the header, taking advantage of the same coding which is noticeably more robust than the one used for payload. Synchronization between transmitting and receiving frames are requested in reporting with short bitmaps. The correct retransmission of badly received radio blocks needs the knowledge of the fixed delay (expressed as a number of RLC/MAC block periods) between the instant of transmission of a radio block and the instant of reception of the short bitmap. A second improvement is to allocate the short bitmap in a new zone placed immediately after the header of the RLC/MAC blocks, and encode it independently of the payload using a more robust coding against the errors than the robustness of the MCS used in the payload data part.
摘要翻译：本发明涉及对在3GPP GERAN移动无线电系统内即将运行的快速ARQ机制的最新提议的改进。快速ARQ利用短路位图，仅跨越传送相关ACK / NACK信令的RLC / MAC块的有效载荷中的少量八位字节。主要的改进是将短位图从有效载荷数据转移到在上行链路或下行链路方向上传输的相同RLC / MAC块的报头。这允许将短位图与报头一起编码，利用与用于有效载荷的编码明显更强的相同的编码。在使用短位图报告时请求发送和接收帧之间的同步。对接收不正确的无线电块的正确重传需要知道无线电块的发送时刻和短位图的接收时刻之间的固定延迟（表示为RLC / MAC块周期数）。第二个改进是将短位图分配在紧邻RLC / MAC块的头部之后的新区域中，并且使用针对错误的更强鲁棒的编码来独立于有效载荷进行编码，而不是在有效载荷中使用的MCS的鲁棒性数据部分。

摘要： A mobile station operating in EGPRS mode needs to the early establishment of an uplink TBF although has not data to send, at the only precautionary purpose of preventing an intolerable latency negatively affecting the subsequent delay-sensitive transmissions. To this aim, the mobile sends a Packet Channel Request message in one phase access mode including a new establishment cause called "Early TBF establishment". The network establishes an uplink TBF indicating the requester and assigns a radio resource on one PDCH channel or more. Then the network schedules the transmission from the mobile station also when it does not have data to transmit other than dummy packets. This is performed through the USF flags in the usual manner. As soon as actual data become available for transmission, the mobile send them instead of dummy packets. In an alternative embodiment the mobile sends the Packet Channel Request message in two phase access mode. As soon as the Packet Uplink Assignment message is received by the mobile station, it send a Packet resource Request message including an Extended Uplink TBF information. The network behaves as in the previous case .

摘要： For indicating lost segments (LS) across layer boundaries an application encoder (AE) generates independently accessible symbols (Sym) , these symbols (Sym) are aggregated by symbol aggregation means (SA) into a packet payload, the aggregated symbols in the packet payload are transported in a defined packet structure (Pl) whereby the packet structure (Pl) is defined by anyone of at least one packet header, a block- check sequence, and a payload of variable length of aggregated independent symbols, these packets are transported over a channel by a packet transmitter (PT) segmenting the packets into different segments (S2) by segmentation means (SE) , a segment receiver (SR*) included in a first entity has the ability to detect whether a certain segment is lost and also knows the length of the lost segment, the segments are aggregated in the first entity to form at least one packet conforming to the packet stream, the one or more packets are delivered to a packet receiver (CPS) in another, second entity by means of a normalized interface (Nil) between the two entities which allows to pass packets according to the specified format from the first entity to the second entity, a symbol parser entity (CPS) recovers the symbols and passes the individual symbols (Sym) to an application decoder (AR) , whereby either correct symbols or erased symbols can be forwarded to the application decoder, the segment receiver (SR*) in the first entity inserts a certain pattern at the position where the lost or defective segment would be which indicates the loss or defect of segment and the length of the lost or defect segment in the aggregated packet, the packet receiver (CPS) in the second entity knows the format, the syntax and the semantics of the inserted pattern, means in the second entity search for specific patterns in the received packet (RPl*) and interpret each found pattern to recover all reliable non-lost information within the packet, and a symbol parser (CPS) in the second entity recovers from the recovered non-lost information of each received packet (RPl*) individual symbols (Sym).

摘要： Method to perform link adaptation at the radio interfaces of an enhanced packet data cellular network handling several Modulation and Coding Schemes (MCS) for maximizing data throughput. In a preliminary off-line step the system behaviour, in terms of net throughput of the various available MCSs, is simulated for different C/l conditions. From the simulation two sets of tables are obtained, each table including upgrade and downgrade thresholds expressed in terms of Block Error Rate (BLER). Thresholds correspond to switching points from an MCs to the two available MCSs having the immediate less or more protection. The two sets of tables are referred to higher or lower diversity RF environments and are further specialized for taking into account EGPRS type II hybrid ARQ, namely Incremental Redundancy (IR). During transmission the transmitted blocks are checked for FEC and the results are sent to the network. The network continuously updates BLER using exponential smoothing. In order to achieve the correct time response, in spite of that RLC blocks can be received or not, a reliability filter is provided whose output is used to decide the weight between the new and old measurements to make the BLER filter impulse response exponentially decreasing with time. The IR efficiency is tested for each incoming block and an indicative variable IR status is filtered using the same approach used for BLER. Each actual threshold of BLER to be used in link adaptation is obtained by a linear interpolation between the tabulated threshold without IR and with perfect IR, both weighed with filtered IR status. Filtered BLER is then compared with said interpolated thresholds for testing the incoming of a MCS switching condition. Power control pursues the goal of maintaining constant QoS peak throughput per time slot.
