Abstract: This disclosure provides methods, components, devices, and systems for wireless communication involving utilizing a service period (SP) margin added at an end of a SP. Some aspects more specifically relate to transmitting data packets during an overlapped time period between SPs of two adjacent TWTs. In some examples, an access point (AP) may transmit a frame including a TWT element indicating a first scheduled SP associated with a first wireless communication device, the first scheduled SP having an overlapping time period with a portion of a second scheduled SP associated with a second wireless communication device. By utilizing the overlapping time period, aspects of the present disclosure may more efficiently transmit or receive data during the service period margin in the overlapping time period. Aspects of the present disclosure may result in a higher efficiency of use for a SP margin and lead to higher efficiency of bandwidth.
