    • The invention relates to a method for indicating the allocation of a set of transmission resources between user stations in a communication system comprising at least a control entity, a transceiver entity and at least one user stations. In the method in the control entity is determined the number of sharing user stations that share the set of transmission resources. In the control entity is determined a combination of transmission resource allocation sizes corresponding to the requirements of each the sharing user station. To the user stations is transmitted from the transceiver entity an allocation table wherein the sharing user stations are identified in an order corresponding to the transmission resource allocation sizes for each the sharing user station. To the user stations is transmitted from the transceiver entity a field identifying the combination of transmission resource allocation sizes.
    • 本发明涉及一种用于指示在至少包括控制实体,收发机实体和至少一个用户站的通信系统中的用户站之间的一组传输资源的分配的方法。 在控制实体中的方法中确定共享用户站的共享传输资源集合的数量。 在控制实体中确定与每个共享用户站的要求对应的传输资源分配大小的组合。 从收发器实体向用户站发送分配表,其中以与每个共享用户站的传输资源分配大小相对应的顺序来标识共享用户站。 从收发器实体向用户站发送标识传输资源分配大小的组合的字段。

    • The invention relates to a communication method for a digital cellular mobile telephone system and a digital cellular mobile telephone system comprising several base stations and mobiles utilizing time division multiple access. In the system communication is carried out on a predetermined frequency band in a predetermined number of time slots having a predetermined length. In the communication between the mobiles and the base station within the TDMA time slot with the predetermined length, the transmissions to communicate information comprising a few bits or several bits from the mobiles communicating with the same base station at least within the same time slot are mutually substantially orthogonal. Preferably, in order to communicate information, preferably information of the on-off type, such as acknowledgments and channel allocation requests, the mobiles communicating with the same base station use substantially orthogonal transmissions at least to the same base station in the same time slot. Preferably each mobile transmits within the TDMA burst of said TDMA time slot of the predetermined length as a part of the burst a predetermined bit sequence corresponding to the transmitted information bit combination, whereby the predetermined frequency band is unchanged. The bit sequences transmitted by different mobiles to the same base station are mutually substantially orthogonal. By using such substantially orthogonal transmissions it is possible to avoid collisions between the communications of information comprising a few or several bits, typically 1 to 10 bits, such as acknowledgments and channel allocation requests, which typically occur in a time division multiple access system.
    • 本发明涉及一种用于数字蜂窝移动电话系统和数字蜂窝移动电话系统的通信方法,该数字蜂窝移动电话系统包括利用时分多址接入的几个基站和移动台。 在具有预定长度的预定数量的时隙中,在预定频带上进行系统通信。 在具有预定长度的TDMA时隙内的移动台和基站之间的通信中,至少在同一时隙内从与相同基站通信的移动台中传送包括几比特或几比特的信息的传输是相互的 基本正交。 优选地,为了传送信息,优选地传送诸如确认和信道分配请求的开 - 关类型的信息,与相同基站通信的移动台在相同时隙中至少使用至少相同的基站的基本上正交的传输。 优选地,每个移动台在预定长度的所述TDMA时隙的TDMA脉冲串内发射作为脉冲串的一部分的与发送的信息比特组合相对应的预定比特序列,由此预定频带不变。 不同移动台向相同基站发送的比特序列相互基本正交。 通过使用这种基本上正交的传输,可以避免包括几个或几个位(通常为1到10位)的信息的通信之间的冲突,例如通常发生在时分多址系统中的确认和信道分配请求。
