    • 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。
