A PUCCH configuration method, comprising: receiving, by user equipment, UE, correspondence indication information sent by a base station, wherein the correspondence indication information is used to indicate a currently-used correspondence, and the correspondence comprises information about a first cell and a second cell corresponding to the first cell, wherein the first cell is a cell for which a physical uplink control channel, PUCCH, is already configured, and uplink feedback information of the second cell is borne by using the PUCCH of the first cell corresponding to the second cell; and determining, by the UE according to the currently-used correspondence, a PUCCH used to send the uplink feedback information of the second cell, wherein the second cell corresponding to the first cell belongs to at least two timing advance groups: a first secondary timing advance group and a second timing advance group, and: when an uplink time alignment timer corresponding to the first secondary timing advance group that comprises the first cell expires, releasing, by the UE, a sounding reference signal, SRS, resource corresponding to a cell in the first secondary timing advance group, and performing, by the UE, at least one of the following processing: releasing, by the UE, a channel quality indicator, CQI, resource configured for the second cell corresponding to the first cell, wherein the second cell comprises a second cell that belongs to the second timing advance group and a second cell that belongs to the first secondary timing advance group; releasing, by the UE, an SRS resource configured for a second cell that corresponds to the first cell and that belongs to the second timing advance group and/or clearing uplink authorization, downlink authorization, and/or hybrid automatic repeat request, HARQ, buffer information that correspond/corresponds to the second cell; deactivating, by the UE, the second cell that corresponds to the first cell and that belongs to the second timing advance group; stopping, by the UE, uplink transmission configured for the second cell that corresponds to the first cell and that belongs to the second timing advance group; or stopping, by the UE, an uplink time alignment timer of the second timing advance group, wherein all cells comprised in the second timing advance group are a second cell corresponding to a first cell comprised in the first secondary timing advance group. receiving, by user equipment, UE, correspondence indication information sent by a base station, wherein the correspondence indication information is used to indicate a currently-used correspondence, and the correspondence comprises information about a first cell and a second cell corresponding to the first cell, wherein the first cell is a cell for which a physical uplink control channel, PUCCH, is already configured, and uplink feedback information of the second cell is borne by using the PUCCH of the first cell corresponding to the second cell; and determining, by the UE according to the currently-used correspondence, a PUCCH used to send the uplink feedback information of the second cell, wherein the second cell corresponding to the first cell belongs to at least two timing advance groups: a first secondary timing advance group and a second timing advance group, and: releasing, by the UE, a channel quality indicator, CQI, resource configured for the second cell corresponding to the first cell, wherein the second cell comprises a second cell that belongs to the second timing advance group and a second cell that belongs to the first secondary timing advance group; releasing, by the UE, an SRS resource configured for a second cell that corresponds to the first cell and that belongs to the second timing advance group and/or clearing uplink authorization, downlink authorization, and/or hybrid automatic repeat request, HARQ, buffer information that correspond/corresponds to the second cell; deactivating, by the UE, the second cell that corresponds to the first cell and that belongs to the second timing advance group; stopping, by the UE, uplink transmission configured for the second cell that corresponds to the first cell and that belongs to the second timing advance group; or stopping, by the UE, an uplink time alignment timer of the second timing advance group, wherein all cells comprised in the second timing advance group are a second cell corresponding to a first cell comprised in the first secondary timing advance group.
