Abstract: There is featured a Direct Mode (DM) communication method between two mobile terminals (MTs) in access point (AP) controlled WLAN systems. The DM connection scheme calls for establishing that an initiating MT and a remote MT are associated to the same AP; establishing that the remote MT supports a DM operation feature; sending, by the AP, address identifiers of the initiating and remote MTs to the remote and initiating MTs, respectively; and sending, to the AP, RSS measurements performed by the initiating and remote MTs of MT identifying messages sent to them by the remote and initiating MTs, respectively. DM communication between the two MTs continues with exchange of information to conclusion when a MT identifying message is satisfactorily received by both MTs and when a MT identifying message of either MT is not satisfactorily received, DM communication setup is terminated.

Abstract: A method is for estimating drift between a first clock used in a digital transmission processing of a first Ultra Wide Band (UWB) pulse train signal and a second clock used in a digital reception processing of a second UWB pulse train signal resulting from a transmission of the first UWB pulse train signal. The method may include sampling the second UWB pulse train signal, and calculating trellis information representative of a trellis having reference paths respectively associated to different reference values of the drift and including sample transitions of a sampled third signal from the sampled second UWB pulse train signal. The method may further include processing the sampled third signal along the trellis for obtaining a path metric for each processed reference path, and selecting the processed reference path having a greatest path metric, the drift being the reference value associated to the selected processed reference path.

Abstract: Successive sequences of interleaved data samples extracted from a virtual memory having L0 columns and C0 rows are de-interleaved. The de-interleaving includes receiving each sequence of the interleaved data samples, and writing row by row the received sequences of interleaved data samples in a de-interleaving memory array having L rows and C columns, with L being greater or equal to L0 and C being greater or equal to C0. The data samples stored in the de-interleaving memory array are de-interleaved sub-array by sub-array. Each sub-array is a square cluster array having a number SQ of rows and columns. A cluster array is a row of the square cluster array comprising SQ data samples, with the number L of rows and the number C of columns of the de-interleaving memory array being multiples of the number SQ of rows and columns.

Abstract: A ARQ actions taken in the data link layer control (DLC) in a wireless communications system for data transmission is implemented by using the HiperLAN/2 protocol that has a selective retransmission process to complete bitmaps when there are errors in data unit transmissions. More particularly it pertains to adaptive allocation of ARQ feedback bandwidth to economize on the use of bandwidth. This is achieved by informing the scheduler of the status of received and non-received data units at the receiver to allow adaptive ARQ feedback bandwidth during data transmission. The information about the status of data units at the receiver is provided by the ABIR flag contained in the ARQ feedback message. If there are many unacknowledged messages of,data units, the ABIR flag is set and the scheduler increases bandwidth to accommodate the traffic of retransmitted messages that were omitted. When the situation has returned to normal, that is, there are minimal messages waiting to be retransmitted the ABIR flag is set to null and no added bandwidth is assigned. This technique can be used also to find the lowest level of bandwidth by decreasing bandwidth until there is a backup in traffic of retransmissions and increasing bandwidth at that time.

Abstract translation: 在用于数据传输的无线通信系统中的数据链路层控制（DLC）中采取的ARQ动作通过使用具有选择性重传过程的HiperLAN / 2协议来实现，当在数据单元传输中存在错误时完成位图。 更具体地说，它涉及ARQ反馈带宽的自适应分配以节省带宽的使用。 这通过在接收机处通知调度器接收到的和未接收的数据单元的状态来实现，以便在数据传输期间允许自适应ARQ反馈带宽。 接收机上数据单元状态的信息由ARQ反馈消息中包含的ABIR标志提供。 如果存在许多未确认的数据单元的消息，则设置ABIR标志，并且调度器增加带宽以适应被省略的重传消息的业务。 当情况恢复正常时，也就是说，等待重发的消息最少，ABIR标志设置为null，没有分配带宽。 这种技术还可以用于通过减少带宽来找到最低级别的带宽，直到在传输流量的备份和当时的带宽增加。
