    • A packet data communication system uses an USF (Uplink State Flag) transmitted on the downlink and interleaved with downlink data, to schedule traffic on the uplink for one or several mobile users utilizing the same physical channel. The USF indication is made variable and defined in the control signaling at setup of a packet transmission. An USF indicates to a mobile that one or several consecutive radio blocks is reserved for uplink transmission from a specific mobile. The mobile does not have to receive the USF during the remaining period defined by the number of radio blocks scheduled. The solution is especially advantageous in combination with adaptive antennas when all radio blocks on the downlink transmissions do not have to be broadcast to all users on a certain channel.
    • 分组数据通信系统使用在下行链路上发送并与下行链路数据交织的USF(上行链路状态标志),以使用相同的物理信道在一个或多个移动用户的上行链路上调度业务。 在设置分组传输时,USF指示被变化并在控制信令中定义。 USF向移动台指示一个或几个连续的无线电块被保留用于来自特定移动站的上行链路传输。 在由计划的无线电块数量定义的剩余时间段内,移动台不必接收USF。 当下行链路传输上的所有无线电块不必向特定信道上的所有用户广播时,该解决方案与自适应天线组合是特别有利的。

    • The present invention relates to a method and an arrangement for channel allocation in a radio communication system in which data is transmitted between two stations over two or more radio channels. Data is communicated as packets which are divided into blocks while the transmission follows a protocol for automatic re-transmission of data that have been erroneously transmitted. In accordance with the proposed method, channels for re-transmission are allocated with respect to a transmission parameter which has been created at a previous transmission and which is based upon information of the result of said previous transmission. The transmission parameter is aimed to ensure that re-transmission is performed via those channels which have the highest probability of transmitting data correctly. The channels which had the highest transmission quality in said previous transmission are expected to have the highest transmission quality also by re-transmission.

    • Automatic repeat request (ARQ) functionality in a cellular mobile packet data communication system using a reservation slotted-ALOHA protocol is provided by assigning a temporary frame identity (TFI) to each data frame transmitted to or from a mobile station. The assigned TFI is unique among concurrent frame transfer sequences in a cell, and may be assigned based on information in a data frame sent to the mobile station or based on information in a channel reservation message that precedes the data frame sent to the mobile station. The TFI may also be assigned based on information in a channel reservation message that precedes a data frame sent from the mobile station, and the TFI assigned is unique among concurrent frame transfer sequences in a cell. The TFI is included in every block belonging to a particular frame, a block being the unit of data on which ARQ is based. A partial data frame to be retransmitted in case of a transmission error contains only the blocks determined by the ARQ protocol type (e.g., selective or Go-back-N) used, whereby a primary block need not be added to identify the mobile station. Blocks belonging to frames destined for different mobile stations can be multiplexed on the downlink based on the TFI. The mobile station may include, in its random access request, an indication that a TFI is already assigned.
    • 通过向从移动台发送的每个数据帧分配临时帧标识(TFI)来提供使用预留时隙ALOHA协议的蜂窝移动分组数据通信系统中的自动重复请求(ARQ)功能。 分配的TFI在小区中的并发帧传输序列中是唯一的,并且可以基于发送到移动站的数据帧中的信息或者基于发送到移动站的数据帧之前的信道预留消息中的信息来分配。 也可以基于在从移动台发送的数据帧之前的信道预留消息中的信息来分配TFI,并且分配的TFI在小区中的并发帧传输序列中是唯一的。 TFI包含在属于特定帧的每个块中,块是ARQ所基于的数据单元。 在发送错误的情况下要重发的部分数据帧仅包含由所使用的ARQ协议类型确定的块(例如,选择性或回退N),由此不需要添加主块来识别移动台。 属于不同移动站的帧的块可以在下行链路上基于TFI复用。 在其随机接入请求中,移动台可以包括已经分配了TFI的指示。

    • The present invention concerns a process in a radio communication system which is arranged for packet data transmission according to a message-synchronized ALOHA protocol with reservation. Mobile stations in the system are arranged to send access requests to a base station during a reservation phase in a mobile radio system which uses this protocol. The base station is arranged to receive and comply with the access request from a first mobile station by sending thereto a channel reservation message (2) comprising a channel reservation (3). The base station is further arranged to receive access requests from at least a second mobile station for which channel reservation momentarily cannot be carried out. According to the process of the invention an access request received from the second mobile station is confirmed when channel reservation cannot be carried out in the usual manner. The confirmation is sent in the form of an access confirmation (4, 5) which is included in the same channel reservation message (2) as the channel reservation (3) for the first mobile station.
    • 本发明涉及一种无线电通信系统中的一种处理方法,该方法根据具有预约的消息同步ALOHA协议进行分组数据传输。 系统中的移动站被安排为在使用该协议的移动无线电系统中的预留阶段期间向基站发送访问请求。 基站被配置为通过向其发送包括信道预留(3)的信道预留消息(2)来接收和遵守来自第一移动台的接入请求。 基站还被布置成从至少第二移动台接收对该信道保留暂时不能被执行的接入请求。 根据本发明的处理,当不能以通常的方式执行频道预约时,确认从第二移动台接收到的接入请求。 以与第一移动台的信道预约(3)相同的信道预留消息(2)中包括的接入确认(4,5)的形式发送确认。
