Data slot allocation method used to transmit uncompressed AV data, and method and apparatus for transmitting uncompressed AV data
First Claim
1. A data slot allocation method used to transmit uncompressed audio/video (AV) data, the method comprising:
- transmitting a first superframe during a first beacon period;
receiving a data slot request frame requesting a data slot for transmitting the uncompressed AV data from at least one wireless device, which belongs to a network, during a data slot reservation period included in the first superframe;
transmitting a response frame to the at least one wireless device during the data slot reservation period in response to the data slot request frame; and
transmitting a second superframe including at least one data slot allocated to the at least one wireless device during a second beacon period,wherein a plurality of contention access periods in which the at least one wireless device transmits data through backoff are distributed between a plurality of data slots in the first superframe, the plurality of data slots respectively indicating a plurality of periods during which the at least one wireless device is assigned to transmit data over the network, the plurality of contention access periods are not placed adjacent each other in the first superframe, and communication with the at least one wireless device is carried out using a carrier frequency of 60 GHz.

Abstract
Provided is a method and apparatus for wirelessly transmitting large data in a more efficient and stable manner. In particular, provided is a data slot allocation method used to transmit uncompressed audio/video (AV) data. The data slot allocation method includes transmitting a first superframe during a first beacon period; receiving a data slot request frame from at least one wireless device, which belongs to a network, during a data slot reservation period included in the first superframe; transmitting a response frame to the at least one wireless device during the data slot reservation period in response to the data slot request frame; and transmitting a second superframe including one or more data slots allocated to the at least one wireless device during a second beacon period.
