Description

Method and terminal for activating secondary cell

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a method and a terminal for activating a secondary cell.

Background

A Long Term Evolution (LTE) system introduces a carrier aggregation technology, where a terminal (e.g., user Equipment (UE)) performs connection communication with a network through multiple cells (cells), where one Cell is a Primary Cell (PCell) and the other cells are Secondary cells (scells). Wherein, the SCell has activation and deactivation states, the PCell has no deactivation state, and the activation state is kept all the time.

The SCell is added at Radio Resource Control (RRC) reconfiguration to provide additional Radio resources, and there is no RRC communication between the SCell and the terminal. The Carrier element corresponding to the SCell is called a Secondary Carrier element (SCC). Here, a downlink carrier of the SCell is referred to as a downlink secondary carrier element (DL SCC), and an uplink carrier of the SCell is referred to as an uplink secondary carrier element (UL SCC). Generally, the network side may determine whether to configure a certain cell as the secondary cell of the terminal according to the measurement report of the terminal.

Currently, for SCell of Carrier Aggregation (CA), the procedure of reactivation completes the start of the following procedures through configuration:

-transmitting sounding reference signals (SRS transmissions on the SCell) within the secondary cell;

-reporting a channel quality indication, a precoding matrix indication, a rank indication, a precoding type indication, channel state information-reference signal resource indicator (CQI/PMI/RI/PTI/CRI reporting for the SCell) of the secondary cell;

-monitoring a physical downlink control channel (PDCCH monitoring on the SCell) on the secondary cell;

-physical downlink control channel monitoring (PDCCH monitoring for the SCell) for the secondary cell;

-physical uplink control channel transmission (PUCCH transmissions on the SCell, if configured) in the secondary cell;

-starting or restarting a deactivation timer associated with the SCell (start or restart the SCell deactivated timer associated with the SCell);

-triggering a power headroom reporting (trigger PHR).

The Activation/Deactivation mechanism of the SCell is implemented based on a combination of an Activation/Deactivation (Deactivation) media access Control Element (MAC Control Element) and Deactivation timers (Deactivation timers).

Wherein the SCell activation/deactivation operation based on the MAC CE is controlled by a base station (e.g., evolved Node B (eNodeB)), and the SCell deactivation operation based on the deactivation timer is controlled by the terminal.

(1) MAC CE based SCell activation/deactivation:

the format of the Activation/Deactivation MAC CE is shown in fig. 1 and 2. The Logical Channel Identity (LCID) of the corresponding MAC subheader (subheader) is 11011 and 11000, respectively.

Ci corresponds to the activation/deactivation status of the SCell for which sCellIndex-r10 is configured as i. If Ci is set to 1, it indicates that the corresponding SCell is activated; if Ci is set to 0, it indicates that the corresponding SCell is deactivated.

(2) SCell deactivation based on deactivation timer:

the terminal maintains a deactivation timer (SCellDeactivationTimer) of one SCell, and the value of the deactivation timer of the SCell is the same for all scells of the terminal. This value may be configured to be "infinity", i.e., SCell deactivation based on a deactivation timer, when the terminal cannot control the deactivation of the SCell.

When the terminal does not receive data or a Physical Downlink Control Channel (PDCCH) message on the corresponding SCell within the time specified by the deactivation timer, the SCell will be deactivated.

The existing process for activating the secondary cell comprises the following steps: terminal measurement reporting; the network side configures the auxiliary cell according to the measurement report of the terminal; activating the secondary cell. This results in a large delay for the activation of the secondary cell.
