It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention.

It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example, Global System of Mobile Communication ("GSM") system, Code Division Multiple Access (Code Division Multiple Access, referred to as "CDMA") system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service ("GPRS"), Long Term Evolution (Long Term Evolution, Referred to as "LTE" system, Long Term Evolution-Advanced (LTE-A) system, LTE Frequency Division Duplex (FDD) system, LTE time division duplex (Time Division Duplex, abbreviated as "TDD"), Universal Mobile Telecommunication System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication system, etc. .

In the embodiment of the present invention, the network device may be a base station, an enhanced base station, a cell, or a relay. The base station may be a base station (Base Transceiver Station, abbreviated as "BTS") in GSM or CDMA, or a base station (NodeB, abbreviated as "NB") in WCDMA, or an evolved base station in LTE ( Evolutional Node B, referred to as "ENB" or "e-NodeB".

The user equipment can also be called a terminal equipment (Terminal Equipment), a mobile station (Mobile Station, MS for short), a mobile terminal (Mobile Terminal), etc., and the user equipment can be accessed via a radio access network (Radio Access Network, referred to as " The RAN") communicates with one or more core networks, for example, the user equipment may be a mobile telephone (or "cellular" telephone), a computer with a mobile terminal, etc., for example, may be portable, pocket, handheld, Built-in computer Or in-vehicle mobile devices that exchange language and/or data with a wireless access network.

FIG. 1 is a schematic block diagram of a user equipment 10 according to an embodiment of the present invention. As shown in FIG. 1, the user equipment 10 includes:

The determining module 11 is configured to determine, according to a state change of the secondary cell SCell configured with the physical uplink control channel PUCCH in the target physical uplink control channel cell group PCG, the target PUCCH to be activated in the target PCG;

The activation module 12 is configured to activate the target PUCCH determined by the determining module 11.

Specifically, the user equipment determines the target PUCCH to be activated in the target PCG according to the state change of the secondary cell SCell in which the physical uplink control channel PUCCH is configured in the target physical uplink control channel cell group PCG, and activates the determination determined by the determining module. The target PUCCH.

Therefore, the user equipment in the embodiment of the present invention determines the target PUCCH to be activated in the target PCG according to the state change of the secondary cell SCell in which the physical uplink control channel PUCCH is configured in the target physical uplink control channel cell group PCG, and activates The target PUCCH can reduce signaling overhead and reduce delay when replacing the PUCCH configuration.

It should be understood that, in the embodiment of the present invention, the activation/deactivation mechanism of the user equipment UE to the SCell is based on a combination of the medium access control control MAC MAC and Deactivation Timers. The MAC CE based SCell activation/deactivation operation is controlled by a network device (eg, a base station eNodeB), and the Deactivation Timer based SCell activation/deactivation operation is controlled by the UE.

For the Deactivation Timer-based SCell activation/deactivation operation, each SCell has a Deactivation Timer, but the Deactivation Timer is the same for all SCells of a certain UE, and is deactivated by the network device (for example, eNodeB) through the secondary cell. (SCellDeactivationTimer) field configuration. The value of the deactivation timer can be configured to be infinity, ie to disable the Timer based Deactivation.

The UE does not receive a data or physical downlink control channel (Physical Downlink Control Channel, hereinafter referred to as "PDCCH") message on a component carrier ("CC") for the time specified by the Deactivation Timer. The Timer will time out and the corresponding SCell will be activated. This is also the only case where the UE can automatically deactivate a SCell. If the UE receives a data or PDCCH message on a CC during the Deactivation Timer operation, the deactivation timer is restarted. When the UE receives an activation command in subframe n, the corresponding operation will be initiated in n+8 subframes. When the UE receives a deactivation command in subframe n Or the Deactivation Timer of an SCell expires, except that the channel state information (CSI) report corresponding operation (stop reporting) is completed in n+8 subframes, and other operations must be in n+8 subframes. Completed inside. However, the invention is not limited to this.

In the embodiment of the present invention, optionally, if the UE receives the data or the PDCCH message sent by the network device on the SCell, and the Deactivation Timer of the SCell is restarted, the PUCCH is configured in the PCG to which the SCell belongs and the PUCCH is configured. The Deactivation Timer corresponding to the SCell in the active state is also restarted.

That is, if the Deactivation Timer corresponding to one of the SCells in a PCG is restarted, the Deactivation Timer corresponding to the SCell in the PCG configured with the PUCCH and the PUCCH in the active state is also restarted. Therefore, it is possible to avoid the problem that the Deactivation Time of the SCell in which the PUCCH is configured and the PUCCH is in the active state is timed out due to the loss of the data packet when the network device restarts the Deactivation Time by scheduling the data.

It should be understood that, in the embodiment of the present invention, an SCell configured with a PUCCH and a PUCCH in an active state may be referred to as a PUCCH SCell, and a target PCG refers to a plurality of serving cells (Serving Cell) of a UE configured with carrier aggregation CA.

In the embodiment of the present invention, the activation module 12 is specifically configured to:

Specifically, if an SCell configured with a PUCCH is activated in the target PCG, when the PUCCH in the target PCG is in a deactivated state, the user equipment may directly activate the determined target PUCCH; if the target PUCCH is in this state If there is an activated PUCCH, that is, one PUCCH in the target PCG is in an active state, the user equipment may activate the target PUCCH while deactivating the activated PUCCH, or may first deactivate the activated PUCCH.
