摘要： The claimed subject matter relates to acquiring channel access in a wireless communication environment. A wireless terminal may transmit first and second sets of tones over respective first and second contiguous transmission periods. The first and second tone sets may be disjoint from each other and may each comprise a number of contiguous tones. The terminal may then refrain from transmitting during a third time period in order to receive a grant signal from a base station in response to the access request. The beginnings of the first time period and the second time period may be a function of a determined uplink transmission time.
摘要翻译：所要求保护的主题涉及在无线通信环境中获取信道接入。无线终端可以在相应的第一和第二连续传输周期上传送第一和第二组音调。第一和第二音调集可以彼此不相交，并且可以各自包括多个连续的音调。然后终端可以在第三时间段期间避免发送，以便响应于接入请求从基站接收授权信号。第一时间段和第二时间段的开始可以是确定的上行链路传输时间的函数。

摘要： Systems and methodologies are described that facilitate scheduling uplink transmissions. For instance, a time sharing scheme can be utilized such that differing mobile devices can be scheduled to transmit during differing time slots; however, it is also contemplated that a static scheme can be employed. Pursuant to an illustration, an interference budget can be combined with a time varying weighting factor associated with a base station; the weighting factor can be predefined and/or adaptively adjusted (e.g., based upon a load balancing mechanism). Moreover, the weighted interference budget can be leveraged for selecting mobile devices for uplink transmission (e.g., based at least in part upon path loss ratios of the mobile devices). Further, disparate interference budgets can be utilized by differing channels of a sector at a particular time. Also, for example, a base station can assign a loading factor to be utilized by wireless terminal(s) for generating channel quality report(s).
