Brief explanation

This abstract describes a technique for protecting and validating the integrity of headers in relayed radio communication. The technique involves adding a token, which includes a temporary identifier, to the header of a data unit (DU) at the adaptation layer. This integrity-protected header is then attached to the DU obtained from the transparent layer and transmitted from the transmitter (TX) to the receiver (RX).

Abstract

A technique for protecting and validating header integrity in a relayed radio communication is described. As to a method aspect of the technique, integrity of a header of a data unit, DU, is protected at an adaptation layer for a relayed radio communication between a remote radio device (-RM) and a radio access network, RAN (-NN), or a further radio device (-RM), through a relay radio device (- RL). A DU is obtained at a transmitter, TX, from a transparent layer, wherein the relayed radio communication uses a protocol stack comprising the adaptation layer below the transparent layer that is relayed transparently at the relay radio device (-RL). The integrity of the header of the DU is protected at the adaptation layer of the TX by including a token in the header of the DU at the adaptation layer, the token comprising a local temporary identifier, ID, of the remote radio device (-RM), wherein the integrity-protected header is attached to the DU obtained from the transparent layer. The DU comprising the integrity-protected header is transmitted from the TX to a receiver, RX.

DATA INDICATOR FOR DCI SCHEDULING MULTIPLE CELLS (18018620)

Main Inventor

Ajit NIMBALKER

Brief explanation

This abstract describes a method for operating a network node in a wireless communication system. The network node configures a message called downlink control information (DCI) to schedule communication between the network and a user equipment (UE) in multiple serving cells. The DCI message does not include a specific field called new data indicator (NDI) for at least one of the serving cells. The network node then transmits this DCI message to the UE. On the UE side, it receives the DCI message which schedules communication in multiple serving cells. The DCI message also does not include an explicit NDI field for one of the serving cells. In response, the UE determines the NDI value associated with the scheduled communication for that serving cell or identifies if there is a new data transmission scheduled for that serving cell.
