A method for implementing wireless communication coverage in an LTE system, comprising: when a User Equipment, UE, accesses a super cell, configuring, by a network side, a Cell Portion, CP, set for the UE according to CP configuration of the super cell; determining, by the network side, an active CP set of the UE according to a receiving power of a signal received from the UE in each CP; and communicating, by the UE, with a CP in the active CP set normally; characterized in that, the determining, by the network side, the active CP set of the UE according to the receiving power of the signal received from the UE in each CP comprises: obtaining, by the network side, an average receiving power of the UE in a single Resource Block, RB, of each CP, according to the receiving power of a channel Sounding Reference Signal, SRS, received from the UE in each CP; obtaining, by the network side, a maximum value of the average receiving powers, and acquiring a reference receiving power of the UE in each CP according to the maximum value; and acquiring, by the network side, a smooth value of the reference receiving power of the UE in each CP according to the reference receiving power and a preset smooth factor; wherein a CP with which the smooth value is associated belongs to the active CP set of the UE, when the smooth value is greater than or equal to a preset judgment threshold for the active CP set. when a User Equipment, UE, accesses a super cell, configuring, by a network side, a Cell Portion, CP, set for the UE according to CP configuration of the super cell; determining, by the network side, an active CP set of the UE according to a receiving power of a signal received from the UE in each CP; and communicating, by the UE, with a CP in the active CP set normally; characterized in that, the determining, by the network side, the active CP set of the UE according to the receiving power of the signal received from the UE in each CP comprises: obtaining, by the network side, an average receiving power of the UE in a single Resource Block, RB, of each CP, according to the receiving power of a channel Sounding Reference Signal, SRS, received from the UE in each CP; obtaining, by the network side, a maximum value of the average receiving powers, and acquiring a reference receiving power of the UE in each CP according to the maximum value; and acquiring, by the network side, a smooth value of the reference receiving power of the UE in each CP according to the reference receiving power and a preset smooth factor; wherein a CP with which the smooth value is associated belongs to the active CP set of the UE, when the smooth value is greater than or equal to a preset judgment threshold for the active CP set. obtaining, by the network side, an average receiving power of the UE in a single Resource Block, RB, of each CP, according to the receiving power of a channel Sounding Reference Signal, SRS, received from the UE in each CP; obtaining, by the network side, a maximum value of the average receiving powers, and acquiring a reference receiving power of the UE in each CP according to the maximum value; and acquiring, by the network side, a smooth value of the reference receiving power of the UE in each CP according to the reference receiving power and a preset smooth factor; wherein a CP with which the smooth value is associated belongs to the active CP set of the UE, when the smooth value is greater than or equal to a preset judgment threshold for the active CP set.
