摘要： Methods and apparatus for use in a wireless system are described where initiation of packet transmission is constrained in accordance to control actual packet transmission in a manner that reduces contention and possible collisions beyond that provided by lower layer resource contention mechanisms, e.g., 802.11 carrier sensing and/or transmission back-off timing mechanisms. Through higher level, e.g., MAC constraints, on packet transmission initiation, an air interface which employs carrier sensing can be used and controlled in a manner which reduces collisions and interference in applications where small packets, e.g., packets which can be transmitted in a fraction of the maximum permitted transmission time. The methods allow small packets in such systems to be transmitted on a periodic or semi-periodic basis in many cases.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be configured to determine a plurality of slots for transmitting information including a plurality of first type slots and a plurality of second type slots where the second type slots have a longer duration that the first type slots. The apparatus may be configured to transmit information in a first type slot when a previous reception was successful and there is no other transmission expected to occur during a gap preceding the first type slot and during the first type slot. Additionally or in the alternative, apparatus may be configured to transmit information in a second type slot when at least one of the previous reception was unsuccessful or there is another transmission expected to occur during a gap preceding the first type slot or during the first type slot.
摘要翻译：提供了一种用于无线通信的方法，装置和计算机程序产品。该装置可以被配置为确定用于发送包括多个第一类型时隙和多个第二类型时隙的信息的多个时隙，其中第二类型时隙具有第一类型时隙的较长持续时间。该装置可以被配置为当先前接收成功并且在第一类型时隙之前的间隙期间和第一类型时隙期间没有预期发生其他传输时，在第一类型时隙中发送信息。附加地或替代地，装置可以被配置为当前一次接收中的至少一个不成功时发送第二类型时隙中的信息，或者预期在第一类型时隙之前的间隙期间或在第一类型时隙期间发生另一个传输。
