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 a check element for a first user device in the group of user devices is based on 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 control information, an identity 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 by appending the previously generated check elements for each user device to the control information;
a transmitter configured to;
transmit the control information message to the group of user devices.

Abstract
The embodiments of the present invention relates to a network node and a user device. 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.

11. A user device for a wireless communication system, the user device comprising:
-
a receiver configured to; receive a control information message addressed for a group of user devices, wherein the control information message comprises control information and a check element for each user device in the group of user devices, and wherein the check element for each user device in the group of user devices are appended to the control information; and a processor configured to; perform a redundancy check on the control information message based on the identity of the user device, and all control information and check elements in the control information message prior to the check element for the user device; derive the control information from the control information message and discard check elements of other user devices upon a positive redundancy check; and wherein the user device is configured to communicate in the wireless communication system based on the control information derived from the control information message. - View Dependent Claims (12, 13)
