Embodiment Construction
[0021] In the embodiment of the present invention, the network side selects a physical resource block from a plurality of physical resource blocks obtained by pre-dividing physical resources according to the channel condition information reported by the terminal, wherein at least two of the plurality of physical resource blocks occupy different numbers of code channels Physical resource blocks, because appropriate physical resource blocks can be allocated according to the terminal channel quality, thereby saving physical resources and improving the utilization rate of physical resources.
[0022] Wherein, each physical resource block occupies at least one code channel, and the network side sends data to the terminal through the code channel occupied by the physical resource block, that is, let the terminal monitor the code channel occupied by the physical resource block allocated to itself.
[0023] The embodiments of the present invention will be further described in detail be...

The invention relates to wireless communication technology, in particular to a physical resource block dispatching method and a device for solving the problems that the terminals positioned at different channel conditions in a district occupy the same physical resource block in the prior art, so as to cause physical resource waste, difficult access of the mobile terminal and high drop call rate. The method of the embodiment of the invention comprises the following steps: the channel quality value of a first terminal is determined according to channel condition information reported by the first terminal; according to the determined channel quality value, one physical resource block is selected from multiple physical resource blocks which are divided in advance, multiple physical resource blocks comprise at least two physical resource blocks which occupy different code channel quantity; the parameters of the selected physical resource block are transmitted to the first terminal. By adopting the method of the embodiment of the invention, the utilization rate of the physical resource can be improved, and the mobile terminal is easy to access the physical resource block.
Description
technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for scheduling physical resource blocks. Background technique [0002] In a VoIP (Voice over IP, IP-based voice call) service, the network side sends data to the terminal side through the code channel corresponding to the physical resource block. [0003] Currently, in the downlink transmission of VoIP services, the number of code channels occupied by the physical resource blocks configured in a cell is the same, for example figure 1 As shown, for example: there are currently 32 code channels, and at this time, there are 4 physical resource blocks occupying 8 code channels in the physical resources; or there are 8 physical resource blocks occupying 4 code channels in the physical resources. [0004] In the FDD (Frequency division duplex, frequency division duplex) system and TDD (Time division duplex, time division duplex) system of the VoIP servic...
