Definitions

  • resource allocation has a critical role in respect of transmission quality and delays in the eyes of a user (that can also be taken as a part of the transmission quality).
  • a network element comprising: means for extending available code space by generating non-orthogonal codes; and means for allocating transmission resources for a user device based on a received first orthogonality measure, a second orthogonality measure and a required transmission quality in such a way that, in addition to the orthogonal codes, the non-orthogonal codes are used.
  • the code space is extended by using non-orthogonal codes that are formed as a linear combination of the original orthogonal codes.
  • the original codes with which the new codes are generated are called base codes.
  • the new codes will be orthogonal against codes other than the base codes.
  • the base codes are typically selected from the same branch of the code tree and hence they are orthogonal against the channelization codes of the other branches of the code tree. In such a case, the reduced code orthogonality will reduce the link performance only for the users having a channelization code from the code tree branch that was used for generating non-orthogonal codes.
  • quantized antenna weights (W ⁇ w 2 ) received from the user device are used for determining the first orthogonality measure in which case the distance between two code words in the space of quantized antenna weight vec- tors tells if the two code words are orthogonal against each other.
  • the first orthogonality measure can be calculated as follows:
  • W 1 denotes a feedback code word (quantized antenna weight vector) of user 1
  • w 2 denotes a feedback code word (quantized antenna weight vector) of user 2
  • W 1 denotes a feedback code word (quantized antenna weight vector) of user k
  • Figure 5 illustrates another simplified exemplary embodiment of a network element in relation to the functionalities required by the allocation method described above. It is obvious to a person skilled in the art that the network element can deviate from what is depicted in Figure 5.
  • the user device also comprises a demodulator 608, which demodulates a received signal so that a data signal can be separated from the carrier wave.
  • the demodulator can also be included in the receiver.
  • the controller part 616 of the user device comprises e.g. controlling and calculating means for controlling the operation of the different parts of the user device and means for processing the user's speech or the data generated by the user, such as a DSP processor ⁇ Digital Signal Processing), which comprises e.g. channel equalizing operations for compensating for the interference caused in the signal by the radio channel, and coding and decoding means which perform both channel coding and speech coding.
  • a DSP processor Digital Signal Processing
  • the generating of the indicators A and B is typically carried out in the DSP processor.
  • the signal spectrum is spread onto a broad band in the transmitter using a pseudorandom spreading code, and in the receiver it is compiled to increase the channel capacity. Coding can also be used for encrypting the output or the information included therein.
