摘要:
A communication terminal is used in a wireless communication environment which involves a plurality of coexisting communication processes with upper limit values being set respectively therein for amounts of data to be transmitted. The communication terminal includes a compressor which compresses data to be transmitted, and a compression controller which controls the compressor to compress the data if the amount of the data to be transmitted is equal to or greater than the upper limit value set depending on one of the communication processes which is to be used to transmit the data.

Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network. includes creating a shortened network identifier having a first length from a full network identifier having a second length. The first length is shorter than the second length. The method further includes generating a compressed beacon including the shortened network identifier. The method further includes transmitting, at an access point, the compressed beacon.

System and method embodiments are provided for compressing data associated with a buffer while keeping delay in data forwarding beyond within about the buffer time. AN embodiment method includes receiving, at a data compression node, data packets from a previous node on a forwarding path for the data packets, compressing the data packets using a compression scheme according to a feedback from buffering the data packets at a buffering node subsequent to the compression node on the forwarding path, and sending the compressed data packets to the buffering node. Another method includes sending, from a buffering node, feedback of buffered data at the buffering node, receiving, from a data compression node, data packets compressed using a compression scheme according to a feedback from buffering the data packets at the buffering node, and transmitting the data packets from the buffering node after a delay time according to the feedback.

A method (30) performed in a device (4a, 4b) for compression of headers of Internet Protocol, IP, packets, is described. The method (30) comprises aggregating (31) a first IP packet (13; 25) and a reference IP packet (12; 24) into a single transmission unit (16); identifying (32) header information elements in the first IP packet (13; 25) to be redundant or non-redundant; indicating (33) the header information elements to be redundant or non-redundant by a bitmap; and compressing (34) the header of the first IP packet (13; 25) according to the bitmap. A corresponding method for decompressing is also provided, and devices, computer programs and computer program products.
