Network node, user device and methods thereof
First Claim
1. A network node for a wireless communication system, the network node comprising:
- a processor configured to;
generate a check element for each user device in a group of user devices, wherein the check element for a first user device in the group of user devices is based on common control information, first user device specific control information and an identity of the first user device, and wherein the check element for each subsequent user device in the group of user devices is based on the common control information, an identity of each subsequent user device, user device specific control information of previous user devices in the group of user devices, and previously generated check elements for the previous user devices in the group of user devices; and
form a control information message by appending the user device specific control information and the check element for each user device to the common control information; and
a transmitter configured to cooperate with the processor to transmit the control information message to the group of user devices.

Abstract
A network node and a user device are provided. The network node comprising: a processor configured to: generate a check element for each user device in a group of user devices; a transmitter configured to: transmit the control information message to the group of user devices. The user device comprising: a receiver configured to: receive a control information message addressed for a group of user devices; a processor configured to: perform a redundancy check on the control information message; derive the control information from the control information message and discard check elements of other user devices upon a positive redundancy check; communicate in the wireless communication system based on the derived control information. Furthermore, the present invention also relates to corresponding methods, a computer program, and a computer program product.
