Abstract: Devices and methods for transmitting data on a radio channel comprise jointly encoding a preamble format with a first random access configuration, thereby forming an extended random access configuration represented by a set of bits. The first random access configuration comprises a combination of a density value and a version index. Each preamble format is associated with a plurality of version indexes.

Abstract: The present invention relates to cellular radio communication and in particular to providing information on neighbour cells to enable terminals to perform neighbour cell measurements. In the prior art the terminal attempts to make neighbour cell measurements in a reference signal structure that is the same in the neighbour cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighbouring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbour cells.

Abstract: In a method of operating a communication network (20) a time division duplex (TDD) frame (F) of information is communicated over a radio interface (32) between a wireless terminal (30) and a base station node (28). The method comprises the wireless terminal (30) receiving plural downlink (DL) subframes of the frame and, in response thereto, configuring a Physical Uplink Control Channel (PUCCH) channel to comprise up to four acknowledgements by using only two PUCCH channel resources and using PUCCH format 1a or PUCCH format 1b. In an example embodiment a PUCCH channel resource is specified by a sequence utilized for transmission of at least part of the PUCCH channel and a cyclical shift applied to the sequence. The two sequences of the respective two PUCCH resources are orthogonal, and the cyclical shift of the two PUCCH resources can be in a frequency domain, a time domain, or both the frequency domain and the time domain.
Abstract translation: 在操作通信网络（20）的方法中，通过无线终端（30）和基站节点（28）之间的无线接口（32）传送信息的时分双工（TDD）帧（F）。 该方法包括无线终端（30），其接收该帧的多个下行链路（DL）子帧，并且响应于此，通过仅使用两个PUCCH信道资源来配置物理上行链路控制信道（PUCCH）信道以包括多达四个确认，并且使用 PUCCH格式1a或PUCCH格式1b。 在示例实施例中，PUCCH信道资源由用于传输至少部分PUCCH信道的序列和应用于序列的循环移位来指定。 相应的两个PUCCH资源的两个序列是正交的，并且两个PUCCH资源的循环移位可以在频域，时域或频域和时域两者中。

Abstract: A mobile terminal camps in a first cell associated with a first reference signal with a first physical structure that relates to a first Time Division Duplex (TDD) allocation of sub-frames for uplink and downlink transmission. The first reference signal is carried by the downlink sub-frames. The mobile terminal detects a broadcast indication of a second physical structure for carrying a second reference signal that relates to a second allocation of sub-frames for uplink and downlink transmissions that differs from the first allocation. The downlink sub-frames according to the second allocation carry the second reference signal. The mobile terminal measures the second reference signal of a neighbor cell as carried by the second physical structure.
