Embodiment Construction

[0034] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which specific embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are given by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Throughout this description, like symbols refer to like elements.

[0035] As mentioned above, figure 1 Shown is the minimum air interface resource in an LTE communication system, which is called a resource element and consists of one OFDM subcarrier over the duration of one OFDM symbol. A resource block consists of 12 OFDM subcarriers on a 0.5 ms slot. The allocation of resource blocks is defined on a TTI of 1 ms, so the smallest scheduling unit is called a resource block pair c...

Abstract

The present invention relates to methods and nodes for scheduling resource blocks in a wireless communication network. The invention also relates to a computer program for carrying out the method according to the invention, and a computer program product comprising a computer-readable medium in which the computer program is embodied. In a first aspect of the present invention, there is provided a method for a radio resource management RRM node (11) in a first cell (12) for facilitating a second adjacent cell (15) for a wireless communication network (10) Scheduling of resource blocks of at least one mobile terminal (UE4, UE5, UE6). The method comprises predicting the allocation of one or more resource blocks to at least one mobile terminal (UE1, UE2, UE3) in a first cell in a subsequent scheduling interval and to an RRM node (14) of a neighboring second cell Send information related to the predicted allocation.

Description

technical field [0001] The present invention relates to methods and nodes for scheduling resource blocks in a wireless communication network. The invention also relates to a computer program for carrying out the method according to the invention, and a computer program product comprising a computer-readable medium in which the computer program is embodied. Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM) modulation is employed in Long Term Evolution (LTE) communication networks, and a network element called a scheduler dynamically allocates OFDM to User Equipment (UE) for uplink or downlink transmission. resource blocks. These resource block allocations include time and frequency allocations. [0003] refer to figure 1 , the smallest physical resource in LTE is called a resource element and consists of one OFDM subcarrier over the duration of one OFDM symbol. A resource block consists of 12 OFDM subcarriers on a 0.5 ms slot. The allocation...
