NETWORK NODE, USER DEVICE AND METHODS THEREOF
First Claim
1. 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 the first user device in the group of user devices is based on control information (d) and the identity (i1) 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 control information (d), the identity (iz) of the subsequent user device and previously generated check elements for previous user devices in the group of user devices,form a control information message (M) by appending the check elements for each user device to the control information (d);
a transmitter configured to;
transmit the control information message (M) to the group of user devices.

Abstract
The present invention relates to a network node and a user device. The network node (100) comprising: a processor (102) configured to: generate a check element for each user device (300z) in a group of user devices (300a, . . . , 300z); a transmitter (104) configured to: transmit the control information message (M) to the group of user devices (300a, . . . , 300z). The user device (300) comprising: a receiver (304) configured to: receive a control information message (M) addressed for a group of user devices (300a, . . . , 300z); a processor (302) configured to: perform a redundancy check on the control information message (M); derive the control information (d) from the control information message (M) and discard check elements of other user devices upon a positive redundancy check; communicate in the wireless communication system (500) based on the derived control information (d). Furthermore, the present invention also relates to corresponding methods, a computer program, and a computer program product.
