Memory allocation method and system, user equipment, and network device

摘要

Embodiments of the present invention provide a memory allocation method and system, a user equipment, and a network device. The method includes: determining, by a user equipment (UE), a high speed downlink shared channel (HS-DSCH) physical layer category for memory allocation according to a first network configuration sent by a first network device; using the total number of soft channel bits corresponding to the determined HS-DSCH physical layer category as a total allocated memory size of a soft memory buffer, dividing the total allocated memory size of the soft memory buffer by the total number of serving or secondary serving HS-DSCH cells corresponding to the determined HS-DSCH physical layer category, and determining a soft memory buffer size of each HS-DSCH transmission channel; and allocating the soft memory buffer size of each HS-DSCH transmission channel among the HARQ processes in the first network configuration of the corresponding HS-DSCH transmission channel.

1. A memory allocation method, comprising:
determining, by a user equipment (UE), a high speed downlink shared channel (HS-DSCH) physical layer category for memory allocation according to a first network configuration sent by a first network device, wherein the first network configuration comprises at least one HS-DSCH transmission channel and the corresponding number of hybrid automatic repeat request (HARQ) processes; using the total number of soft channel bits corresponding to the determined HS-DSCH physical layer category as a total allocated memory size of a soft memory buffer, allocating the total allocated memory size of the soft memory buffer among the HS-DSCH transmission channels, and determining a soft memory buffer size of each HS-DSCH transmission channel, wherein the soft memory buffer size of each HS-DSCH transmission channel is obtained by dividing the total allocated memory size of the soft memory buffer divided by the total number of serving or secondary serving HS-DSCH cells corresponding to the determined HS-DSCH physical layer category, wherein the total number of serving or secondary serving HS-DSCH cells corresponding to the determined HS-DSCH physical layer category is the total number of HS-DSCH transmission channels supported by the UE, and the total number of serving or secondary serving HS-DSCH cells corresponding to the determined HS-DSCH physical layer category is not equal to the number of HS-DSCH transmission channels configured by the first network device for the UE; and allocating the soft memory buffer size of each HS-DSCH transmission channel among the HARQ processes in the first network configuration of the corresponding HS-DSCH transmission channel.
