Apparatus and method for transmitting/receiving data in communication system
TLDR
In this paper, a data transmission apparatus in a communication system includes a reception unit configured to receive terminal information from a plurality of terminals through a new frequency band for transmission and reception of data between the plurality of users and an AP (access point), and a determination unit that determines access timing of the terminals to the AP by using the terminal information, and generate terminal access information including information on the access timing.Abstract:
A data transmission apparatus in a communication system includes a reception unit configured to receive terminal information from a plurality of terminals through a new frequency band for transmission and reception of data between the plurality of terminals and an AP (access point); a determination unit configured to determine access timing of the terminals to the AP by using the terminal information, and generate terminal access information including information on the access timing; and a transmission unit configured to transmit the terminal access information and beacon frames to the terminals, wherein the terminals access the AP and transmit data frames to the AP, at the access timing based on the beacon frames.read more

Enhanced block-request streaming using cooperative parallel HTTP and forward error correction
TL;DR: A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be serve by the file server, which might or might not include a cache as mentioned in this paper.

Enhanced block-request streaming system for handling low-latency streaming
Michael Luby,Mark Watson,Lorenzo Vicisano,Payam Pakzad,Bin Wang,Ying Chen,Thomas Stockhammer,Jaber Mohammad Borran +7 more
TL;DR: In this article, a block-request streaming system provides for low-latency streaming of a media presentation, where a plurality of media segments are generated according to an encoding protocol, and each media segment includes a random access point.
Patent
Switch signaling methods providing improved switching between representations for adaptive http streaming
TL;DR: In this article, the authors propose switch signaling methods for adaptive HTTP streaming, which can be used to enhance existing deployments in such a way that there is no need to change existing content encoding and formatting processes, and that existing clients that receive and play out content are unaffected.

On the optimality of multiantenna broadcast scheduling using zero-forcing beamforming
Taesang Yoo,Andrea Goldsmith +1 more
TL;DR: It is shown that a zero-forcing beamforming (ZFBF) strategy, while generally suboptimal, can achieve the same asymptotic sum capacity as that of DPC, as the number of users goes to infinity.
Patent
Physical layer frame format for WLAN
TL;DR: In this article, a first field and a second field are generated to be included in a preamble of the data unit to determine the duration of a data unit and modulated using a modulation scheme specified for a field corresponding to the first field.

Method and system for providing beamforming feedback in wireless communication systems
TL;DR: In this paper, a transmitter/initiator sends a first frame comprising training symbols, and a receiver/responder receives the first frame, determines the amount of time to generate feedback information, and determines the time to send the feedback information.
Patent
Receiver-driven layered error correction multicast over heterogeneous packet networks
TL;DR: In this paper, a receiver-driven layered multicast (RLM) of real-time media over a heterogeneous packet network such as the Internet is proposed, where each receiver can separately optimize the quality of received audio and video information by subscribing to at least one error correction layer.
