Definitions

  • the present invention relates to a wireless communication system including at least one base station and at least one wireless transmit/receive unit (WTRU) that communicate with each other via uplink (UL) and downlink (DL) coded composite transport channels (CCTrCHs). More particularly, the present invention relates to updating the transmission power of the DL and UL CCTrCHs differently based on whether or not discontinuous transmission (DTX) is employed on the feedback link from which the transmit power control (TPC) commands are received.
  • WTRU wireless transmit/receive unit
  • DL downlink
  • CCTrCHs coded composite transport channels
  • Closed-loop power control is a technique widely used in wireless communication systems such as universal terrestrial radio access (UTRA) frequency division duplex (FDD), UTRA time division duplex (TDD) 3.84/1.28 Mcps, code division multiple access (CDMA) one, or the like.
  • UTRA universal terrestrial radio access
  • FDD frequency division duplex
  • TDD time division duplex
  • CDMA code division multiple access
  • the transmission power of a WTRU or base station is adjusted periodically according to feedback information sent in the opposite link by a receiver in the base station or WTRU.
  • a DL which controls the power transmitted by a base station for a specific WTRU.
  • the WTRU receives the signal from the base station during a certain period of time, (e.g., a time slot or a frame), and determines whether or not the transmission power of the base station needs to be adjusted up or down using a particular quality criterion, such as the signal-to-noise-plus-interference ratio.
  • a particular quality criterion such as the signal-to-noise-plus-interference ratio.
  • the WTRU sends, along with other UL data, a TPC command containing the relevant information for the base station to adjust its transmission power at the subsequent DL transmission.
  • the TPC command contains only one information bit indicating whether the power should be increased or decreased by a predetermined amount, or step size.
  • the accuracy of the power adjustment may be improved by using more than one information bit per TPC command, (allowing multiple step sizes), or by increasing the frequency of the TPC commands.
  • the disadvantage of doing this is that the amount of transmitted UL data needs to be reduced to create room for this additional TPC information.
  • DL power control for dedicated physical channels (DPCHs) and physical DL shared channels (PDSCHs) is closed-loop and works in the manner described in the above paragraphs.
  • PDSCHs physical DL shared channels
  • UL power control is also closed-loop for DPCHs and physical uplink shared channels (PUSCHs).
  • Each TPC command (up or down) consists of one information bit.
  • the TPC step size (up or down) can be 1 dB, 2 dB or 3 dB and is determined at radio link setup.
  • a DL channel is associated to at least one UL channel that provides one or more TPC commands.
  • This DL channel may be a multiplexed channel of several transport channels (TrCHs), where each TrCH can carry a different communication service. This multiplexed channel is referred to as a CCTrCH.
  • a UL CCTrCH is associated to a DL CCTrCH that provides the TPC commands.
  • a CCTrCH subject to power control (a DL CCTrCH for DL power control, a UL CCTrCH for UL power control), is referred to as the power- controlled CCTrCH.
  • a feedback CCTrCH is the CCTrCH to which the power- controlled CCTrCH is associated, and which provides it with the TPC commands, (a UL CCTrCH for DL power control, a DL CCTrCH for UL power control).
  • the base station or WTRU transmitting the power-controlled CCTrCH also receives the feedback CCTrCH, while the base station or WTRU receiving the power- controlled CCTrCH also transmits the feedback CCTrCH.
  • DTX is employed in UTRA TDD systems, (1.28 Mcps and 3.84
  • Mcps on a CCTrCH basis when tliere is no data to transmit for this CCTrCH.
  • a CCTrCH supports part or all of t ie transmissions of a user.
  • a user may use one or several CCTrCH's within a given timeslot.
  • DTX When DTX is activated for a CCTrCH, there will be no transnxission on any physical channel supporting this CCTrCH, except for the first pnysical channel and only every special burst generation period (SBGP) frames (for uplink) or every special burst scheduling parameter (SBSP) frames (for DL), where SBGP or SBSP is configured at radio link setup.
  • SBGP special burst generation period
  • SBSP special burst scheduling parameter
  • DTX is used on a UL CCTrCH.
  • This UL CCTrCH is the feedback, (i.e., the CCTrCH providing the TPC command), for a DL power-controlled CCTrCH.
  • the TPC command is only transmitted when the special burst is transmitted, i.e., at every SBGP frame.
  • the frequency transmission power updates are reduced dramatically and the result can be poor performance for the power-controlled CCTrCH.
  • the same problem would occur in UTRA TDD (1.28 Mcps option only) when DTX is used on a DL CCTrCH and when this DL CCTrCH is the feedback CCTrCH for a UL CCTrCH. In this case, the UL performance would suffer. However, this performance deterioration could be mitigated if the TPC size were increased while the feedback (UL) CCTrCH is in DTX.
  • a single TPC step size is used regardless of the frequency at which the TPC commands arrive on the feedback CCTrCH.
  • the TPC commands may arrive from 2 to 256 times less frequently than in a normal transmission (depending on the value of the SBGP or SBSP).
  • SBGP SBGP
  • SBSP SBGP-BSP
  • a second option is to use a TPC step size optimized for DTX transmission on the feedback CCTrCH, and experience sub-optimal performance in the power-controlled CCTrCH during normal transmission on the feedback CCTrCH. Sub-optimal performance would result from using a larger-than- necessary TPC step size during normal transmission on the feedback CCTrCH, when TPC commands arrive frequently.
  • a third option is to reduce the special burst periodicity (SBGP or
  • SBSP SBSP
  • a fourth option is to use more than one information bit in the TPC command, enabling the node transmitting the feedback CCTrCH to signal a larger step size when it is using DTX.
  • this has the disadvantage of reducing the capacity of the feedback CCTrCH as explained earlier.
  • None of these options is satisfactory, and would result in a loss of system performance. What is needed is enhanced performance in both normal and DTX cases for the feedback CCTrCH.
