Communication with compressed headers

摘要

Communication efficiency may be enhanced by using compressed headers. In an example embodiment, a method is performed by a transmitting device to reduce header size. A mapping is created between a logical channel identifier and a compressed logical channel identifier. The compressed logical channel identifier occupies fewer bits than the logical channel identifier. The mapping is transmitted to a receiving device. A compressed header that includes the compressed logical channel identifier is formulated. A communication that includes the compressed header is transmitted to the receiving device. In another example embodiment, a method is performed by a receiving device to decode a header having a reduced size. A mapping and a communication including a compressed header are received. A compressed logical channel identifier is extracted from the compressed header. A logical channel identifier is recovered from the compressed logical channel identifier using the mapping.

主权项

1. A method that is performed by a transmitting device to reduce header size, the method comprising the steps of:
reducing, by the transmitting device, a number of available medium access control MAC services in comparison to a number of all available medium access control MAC services according to a number of bits available for coding of a compressed logical cell identifier field, the number of bits available for coding of the compressed logical cell identifier field being lower than the number of bits used for coding logical channel identifiers for all available MAC services; creating, by the transmitting device, a mapping between a subset of logical channel identifiers used for all available medium access control MAC services and compressed logical channel identifiers; transmitting, by the transmitting device, the mapping to a receiving device; formulating, by the transmitting device, a compressed header that includes the compressed logical channel identifier field; and transmitting, by the transmitting device, to the receiving device a communication that includes the compressed header.
