Definitions

  • Embodiments of the present invention relate to the field of communications and, more particularly, to methods and apparatus for configuring resources. Background technique
  • the network side allocates different orthogonal variable spreading factors (Orthogonal Variable Spreading Factor) for different users of a cell.

  • OVSF code resource is an important resource for downlink transmission.
  • the High Speed Downlink Packet Access (HSDPA) service is introduced in the fifth version (Release 5) of the Partnership Project, called "3GPP". All HSDPA users in a cell share multiple high-speed shared control channels (High Speed-Shared Control Channel, called "HS-SCCH”) and high-speed physical downlink shared channels (High Speed-Physical Downlink) by time division and code division.

  • the HSDPA data throughput capability that a cell can provide is substantially proportional to the OVSF code resource of the HS-PDSCH that can be used in the cell. Since the A-DPCH of each HSDPA user occupies one OVSF code resource, the OVSF code resource consumed by the A-DPCH increases as the number of HSDPA users increases, in other The OVSF code resources available to the HS-PDSCH will follow the HSDPA user when the common channel, Adaptive Multi-rate ("AMR") voice, and HS-SCCH consumed OVSF code resources remain unchanged. The increase in the number is reduced, resulting in a decrease in HSDPA data throughput that HSDPA users can share in the cell. Therefore, how to reduce the OVSF code resource occupied by the A-DPCH of the HSDPA user is an urgent problem to be solved. Summary of the invention
