METHODS, A WIRELESS DEVICE, A RADIO NETWORK NODE FOR MANAGING A CONTROL BLOCK

摘要

Methods, a wireless device (110) and a radio network node (120) for managing a control block are disclosed. An extended Temporary Flow Identifier, eTFI, is assigned to the wireless device (110) by the radio network node (120). The radio network node (120) constructs the control information. The radio network node (120) performs a bit-wise modulo two addition with a control block and a combination of the eTFI and a pre-determined bit pattern to obtain a modified control block. The radio network node (120) adds channel coding redundancy. The radio network node (120) maps the modified control block onto physical resources. The radio network node (120) sends the modified control block to the wireless device (110). The wireless device (110) decodes the received modified control block removing the channel coding redundancy, performs a bit-wise modulo two addition between the modified control block and a combination of the eTFI and a pre-determined bit pattern to obtain a control block. The wireless device (110) decodes the control block using FIRE-decoding to obtain the control information. The wireless device (110) determines it is the intended recipient of the control information if the TFI information therein matches its assigned TFI. Corresponding computer programs and carriers therefor are also disclosed.

1. A method, performed by a wireless device, for managing a modified control block, wherein the modified control block carries control information for the wireless device, wherein the wireless device is served by a radio network node, wherein a Temporary Flow Identifier, TFI, and an extended Temporary Flow Identifier, eTFI, are assigned to the wireless device by the radio network node, wherein the method comprises:
receiving the modified control block from the radio network node; performing a bit-wise modulo two addition between the modified control block and a combination of the eTFI and a pre-determined bit pattern to obtain a control block; and decoding the control block using FIRE-decoding to obtain the control information, wherein the wireless device is an intended recipient of the control information when a TFI field of the control information matches the TFI assigned to the wireless device.
