Abstract: The invention relates to a method, apparatus and system for configuring control channels in a mobile communication network and a mobile station. In order to suggest another improved scheme for configuring control channels, in particular control channels related to the transmission of user data the invention suggests aligning the size of the control channel information of different formats to an equal number of coded control channel information bits and/or modulation symbols for each control channel. The control channels may comprise scheduling related control information. According to another aspect of the invention, the size of the control channel information is aligned by means of modulation and/or coding, however the control channel information is aligned to one out of a set of numbers of coded control channel information bits and/or modulation symbols for each control channel.

Abstract: A method and a radio base station for interleaving control channel data to be transmitted in a telecommunications system are described. The method comprises grouping the control channel elements CCE1-CCEn into a first order of control channel symbol groups, adding symbol groups comprising dummy values or zeros to the first order of control channel symbol groups based on a number of available symbol group positions for the shared control channel, interleaving the first order of the control channel symbol groups resulting in an a second order, and mapping the second order of control channel symbol groups to the available control channel transmission resources.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for design of hybrid automatic repeat request (HARQ) feedback bits. The method generally includes obtaining a payload to be transmitted, partitioning the payload into a plurality of blocks, and partitioning each block of the plurality of blocks into a plurality of sections. The method also includes deriving redundancy check information for each section of the plurality of sections, and generating a plurality of codewords, each comprising a block of the plurality of blocks and the redundancy check information for each section of the block, wherein a location of each of the sections in the codewords is determined based on an error rate corresponding to each of the sections.

Abstract: A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is, Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to “ping” a UE (18).

Abstract: A wireless communication terminal is disclosed. The wireless communication terminal includes a transceiver transmitting/receiving a wireless signal, and a processor controlling an operation of the wireless communication terminal. The transceiver obtains a signaling field from a physical frame including data to be transmitted from a base wireless communication terminal to each of a plurality of wireless communication terminals including the wireless communication terminal, and receives, from the physical frame based on the signaling field, the data having been transmitted from the base wireless communication terminal to the wireless communication terminal. The signaling field signals information about the plurality of wireless communication terminals. The base wireless communication terminal is any one wireless communication terminal different from the plurality of wireless communication terminals.
