Description

PHR triggering method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a PHR trigger method, a terminal device, and a network device.

Background

Currently, a CA (Carrier Aggregation) technology is introduced into an LTE (Long Term Evolution) system. The CA technology is a technology in which one UE (User Equipment) performs connection communication with a network through a plurality of cells, one of which is a primary cell Pcell and the other of which is a secondary cell Scell. The Scell has an activation state and a deactivation state, the Pcell has no deactivation state, and the activation state is kept all the time. The Activation and Deactivation mechanism of the UE is implemented based on the combination of Activation/Deactivation MAC Control elements (Activation/Deactivation media access Control elements) and Deactivation Timers (Deactivation Timers).

For the Scell of CA, the following initiation of several processes is currently done during the activation process:

-if the MAC entity receives an Activation/Deactivation MAC control element in this TTI activating the Scell，the MAC entity shall in the TTI according to the timing defined in：

-activating Scell; the functions initiated during this activation process include:

-transmitting sounding reference signals (SRS transmissions on the Scell) on the Scell

Reporting CQI (Channel Quality Indicator)/PMI (Precoding Matrix Indicator)/RI (rank Indicator)/PTI (Precoding Type Indicator)/CRI (Channel State Information Reference symbol Resource Indicator) Information (CQI/PMI/RI/PTI/CRI reporting for the Scell)

-monitoring a PDCCH (Physical Downlink Control Channel) on the current Scell (PDCCH monitoring on the Scell)

-monitoring the PDCCH of the current Scell (PDCCH monitoring for the Scell)

-if a PUCCH (Physical Uplink Control Channel) is configured in the current Scell, transmitting the PUCCH (PUCCH transmissions on the Scell, if configured) in the current Scell

-starting or restarting a deactivation timer of the Scell (start or restart the Scell deactivation timer associated with the Scell)

-triggered power headroom reporting (trigger PHR)

Specifically, the PHR (Power Headroom Report) is configured to Report a difference between the estimated uplink transmission Power and the maximum transmission Power of the UE to the base station eNodeB, and the PHR provides information for Power control and scheduling for the eNodeB. The RRC (Radio Resource Control) configures a periodic PHR report Timer (periodicPHR-Timer), a PHR prohibit Timer (prohibitPHR-Timer), and a downlink loss variation (pathchange dB) to Control the PHR process.

The triggering condition of PHR generally includes the following conditions:

(1) when the UE has uplink resources for transmitting new data, the prohibitPHR-Timer is overtime or has overtime, and after the last transmission power headroom report, the change value of the path loss exceeds the configured dl-pathlossChange dB;

(2) the periodicPHR-Timer times out;

(3) when the RRC layer configures or reconfigures the PHR function or parameter, and the configuration or reconfiguration is not to close the PHR operation;

(4) activating a certain uplink carrier;

(5) adding a certain uplink carrier;

(6) when the UE has uplink resources for transmitting new data, the prohibitPHR-Timer is overtime or has overtime, and the power backspace variation quantity corresponding to a certain uplink carrier exceeds the configured dl-pathlossChange dB.

In order to reduce the delay from the deactivated state to the activated state of the Scell, the 5G system introduces a New fast carrier activation state (New Scell fast activation state) for the Scell, where the New fast carrier activation state is a state between the activated state and the deactivated state. In the new state, the state transition does not introduce L1 signaling, allows periodic CQI reporting based on CRS, and does not monitor PDCCH, but is not limited to CQI reporting, and may also include partially activated state behaviors such as sending SRS, or receiving PDSCH. However, currently, for a new state introduced in a 5G system, there is no clear way to trigger PHR for this state.

Detailed Description

Referring to fig. 1A, an embodiment of the present invention provides a PHR trigger method, which is applied to a terminal device, and includes the following steps:

step 101: and receiving the MAC CE transmitted by the network equipment.

The MAC CE in this step is used to instruct the secondary cell to switch from the deactivated state to the new state, or from the activated state to the new state, or to enter the new state, or from the new state to the activated state, or from the deactivated state to the activated state, or to enter the activated state. The New state is specifically a New state (New Scell fast activation state) introduced for the secondary cell (Scell), and is between the activated state and the deactivated state. In the new state, no L1 signaling is introduced for state transition, allowing periodic CQI reporting based on CRS, and no PDCCH is monitored. This new state can be introduced, for example, in a 5G system.

Note that the MAC CE is indication information transmitted by the network device. The network device may simultaneously transmit one (for one Scell) or multiple (for multiple scells) MAC CEs to the terminal device, and the content indicated by each MAC CE may be the same or different, so that the terminal device performs corresponding operations according to the received MAC CE.

Step 102: the PHR is triggered when the process of converting the secondary cell state according to the MAC CE is completed.

In the embodiment of the present invention, when the MAC CE indicates that the secondary cell is converted into or enters a new state, the terminal device may convert the state of the secondary cell into the new state according to the MAC CE, and when the conversion process is completed, the terminal device may, in addition to triggering the PHR, start or restart a Scell Deactivation Timer (Scell Deactivation Timer) corresponding to the secondary cell, and when the secondary cell enters the new state, execute the following operations in a corresponding carrier unit: and performing periodic CQI reporting based on the CRS, and not monitoring the PDCCH, but not only the CQI reporting, but also partial active state behaviors such as sending SRS or receiving PDSCH and the like.

When the MAC CE indicates that the secondary cell is converted into or enters the active state, the terminal device may convert the state of the secondary cell into the active state according to the MAC CE, and when the conversion process is completed, the terminal device may, in addition to triggering the PHR, start or restart an sCell Deactivation Timer corresponding to the secondary cell, and when the secondary cell enters the active state, perform the following operations in a corresponding carrier unit: sending an SRS, reporting CQI/PMI/RI/PTI/CRI, monitoring a PDCCH in the current Scell, monitoring the PDCCH of the current Scell, and sending the PUCCH in the current Scell if the PUCCH is configured in the current Scell.

In the embodiment of the invention, after the new state is introduced, the PHR prohibit PHR-Timer in the PHR can be effective to the new state as well. Further, the prohibitPHR-Timer valid for the new state may be multiplexed with an existing prohibitPHR-Timer (e.g., in an existing LTE system) or may be a newly introduced prohibitPHR-Timer. The prohibitPHR-Timer that is valid for the new state may be configured by the network side.

Specifically, as shown in fig. 1B, before step 101, the triggering method may further include:

step 103: receiving configuration information sent by network equipment, wherein the configuration information comprises a PHR prohibition timer configured for at least one uplink carrier of the terminal equipment by a network side;

step 104: according to the configuration information, a PHR prohibit timer is set.

It should be noted that the configuration information includes a power control related parameter configured by the network side for at least one uplink carrier of the terminal device, where the power control related parameter specifically is: the PHR forbids a Timer prohibitPHR-Timer corresponding to the uplink carrier, a period PHR corresponding to the uplink carrier reports a Timer periodicPHR-Timer and a downlink path loss variation PathlossChange dB corresponding to the uplink carrier.

In addition, in a specific implementation, the network side may also configure a deactivation timer sCellDeactivationTimer for at least one uplink carrier of the terminal device, and the terminal device maintains one sCellDeactivationTimer, where values of the scells of the corresponding terminal device and the sCellDeactivationTimer are the same. The value of sCellDeactivationTimer may be configured to infinity, "infinity", that is, deactivation based on the corresponding SCell is disabled, and at this time, the terminal device cannot control deactivation of the SCell.

Further, in order to prevent the PHR from being triggered too frequently due to the state transition of the terminal device, the terminal device may determine whether to trigger the PHR according to whether the corresponding PHR prohibit timer is running. Specifically, referring to fig. 1B, step 102 may include:

step 1021: when the process of converting the state of the secondary cell according to the MAC CE is finished, judging whether a PHR prohibition timer is running;

step 1022: if the PHR prohibit timer is not running, the PHR is triggered. Wherein the terminal device does not trigger the PHR when the PHR prohibit timer is running.

In this way, whether or not to trigger the PHR is determined by whether or not the PHR inhibition timer is running, and thus, it is possible to prevent the PHR from being triggered too frequently due to state transition of the terminal device.

Referring to fig. 2, an embodiment of the present invention further provides a PHR triggering method, which is applied to a network device, and includes the following steps:

step 201: and transmitting the MAC CE to the terminal equipment.

The MAC CE is configured to instruct the secondary cell to switch from a deactivated state to a new state, or switch from an activated state to a new state, or enter a new state, or switch from a new state to an activated state, or enter an activated state.

Step 202: and receiving the PHR sent by the terminal equipment.

Wherein the PHR is triggered when the process of converting the state of the secondary cell according to the MAC CE is completed by the terminal device.

In the PHR triggering method according to the embodiment of the present invention, by sending the MAC CE to the terminal device, where the MAC CE is used to indicate that the secondary cell is switched from the deactivated state to the new state, or from the activated state to the new state, or enters the new state, or from the new state to the activated state, or enters the activated state, the terminal device can trigger the PHR when the process of switching the state of the secondary cell according to the MAC CE is completed, so as to determine how to trigger the PHR after the new state is introduced.

Further, before step 201, the triggering method may further include:

sending configuration information to the terminal equipment;

a triggering module 32, configured to trigger the PHR when the process of converting the state of the secondary cell according to the MAC CE is completed.

The terminal device of the embodiment of the invention receives the MAC CE sent by the network device, wherein the MAC CE is used for indicating the auxiliary cell to be switched from the deactivation state to the new state, or from the activation state to the new state, or to enter the new state, or from the new state to the activation state, or to enter the activation state, and when the process of switching the state of the auxiliary cell according to the MAC CE is completed, the PHR is triggered, so that how to trigger the PHR after the new state is introduced can be determined.
