摘要： A method for use in multicellular communication network system of the type having base stations and a plurality of remote stations. The method achieves reliable and fault tolerant synchronization between the stations in a call when a frequency hopping technique is used. The method includes steps for acquiring the frequency hop sequence by remote station and tracking the frequency hop sequence after acquisition in order to stay in synchronism. The method also provides for recovering from loss of synchronism and for staying in synchronism.

摘要： A Medium Access (MAC) Protocol is utilized for wireless radio access for a plurality of remote stations to a base station on a LAN. The MAC protocol is based on a reservation scheme for user data traffic and a random access technique for control and signalling traffic. There is a time division fixed frame structure in which time is slotted, and time slots are grouped into fixed frames consisting of data and control subframes or periods. The fixed frame structure consists of three periods (A, B, and C) along with their respective headers. The first period, the A period, is the outbound channel which is used exclusively for data transfer from the base station to the remote stations. The following period, the B period, is the inbound channel that is used for contention-free data transfer from the remote stations to the base station. The allocation of the data slots in the A and B periods is performed by the base station. The last period of the frame, designated as the C period, is the control channel used for the transmission of reservation requests and data from the remote stations to the base station in a random-access contention mode using a slotted Aloha protocol. The duration of the three periods may be varied using a movable boundary technique. The base station estimates the number of actively transmitting remote stations utilizing feedback information from the remote stations. This estimate is broadcast to the remote stations as control indicia to control their transmission attempts in the C period, thus yielding high transmission efficiency.

摘要： A control system for automated management of frequency-hopping in a radio network. The system includes a Wireless Network Manager (WNM) or Controller and a Wireless Control Agent (WCA), which control the distribution and maintenance of hopping patterns in the radio network. In a single cell network, the WNM and the WCA are included in a single base station. In a multiple cell network, the WNM is in a specific station on a LAN, and a WCA is located in each base station on the LAN. In each instance, the WNM is a centralized managing station and the WCA acts as a cell controller.

摘要翻译： 媒体接入（MAC）协议用于多个远程站到LAN上的基站的无线电接入。 MAC协议基于用于用户数据业务的预留方案和用于控制和信令业务的随机接入技术。 存在时分固定帧结构，其中时隙被分段，时隙被分组成由数据和控制子帧或周期组成的固定帧。 固定帧结构由三个周期（A，B和C）及其各自的报头组成。 第一个周期是A周期，是专用于从基站到远程站的数据传输的出站信道。 以下周期，B周期是用于从远程站到基站的无竞争数据传输的入站信道。 在A和B周期中的数据时隙的分配由基站执行。 指定为C周期的帧的最后一个周期是用于使用时隙Aloha协议以随机接入争用模式从远程站向基站传送预留请求和数据的控制信道。 可以使用可移动边界技术来改变三个周期的持续时间。 基站使用来自远程站的反馈信息估计主动发送的远程站的数量。 该估计作为控制标记广播到远程站，以在C周期中控制其传输尝试，从而产生高传输效率。
