Abstract: An embodiment takes the form of a process that includes transmitting video frames to a receiving device during a first transmission period of one or more time slots of a half-duplex air interface, and receiving feedback messaging from the receiving device during a feedback period of one or more time slots of the half-duplex air interface. The process further includes suspending, after the first transmission period, transmission of video frames for a suspension period of one or more time slots of the half-duplex air interface, and after the feedback period and after the suspension period, transmitting one or more recovery frames to the receiving device during a recovery period of one or more time slots of the half-duplex air interface. The one or more recovery frames collectively include inter-coded macroblock data and/or intra-coded macroblock data.

Abstract: A method for assigning slot reservations to subscriber radios in a TDMA communications system, where data is arranged into a series of superframes, includes an inbound signaling protocol having a plurality of inbound transmission slots. An outbound signaling protocol includes an inbound reservation scheduling slot, which includes a plurality of subscriber access code fields. Each subscriber access code field corresponds to at least one of the inbound transmission slots. Each subscriber access code field may store a subscriber access code associated with a subscriber radio. The inbound reservation scheduling message includes a subscriber access code in at least one of the subscriber access code fields. As such, the subscriber radio associated with the subscriber access code may transmit data during the inbound transmission slot corresponding to the subscriber access code in which the subscriber access code field is stored.

Abstract translation: 一种在数据被布置成一系列超帧的TDMA通信系统中为用户无线电分配时隙预留的方法包括具有多个入站传输时隙的入站信令协议。 出站信令协议包括入站预留调度时隙，其包括多个用户接入码字段。 每个用户接入码字段对应于入站传输时隙中的至少一个。 每个用户接入码字段可以存储与订户无线电相关联的用户接入码。 入站预约调度消息在至少一个用户接入码字段中包括用户接入码。 这样，与用户接入码相关联的用户无线电可以在对应于其中存储用户接入码字段的用户接入码的入站发送时隙中发送数据。
