Description

Information indicating method, receiving method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information indicating method, an information receiving method, a network device, and a terminal.

Background

The existing DRX (discontinuous reception) mechanism can enable the terminal to monitor data only in a part of time in one cycle. If the data is monitored, continuing monitoring in the subsequent part of time; if the data is not monitored, the mobile terminal enters the sleep mode in other time in the period, and therefore the purpose of saving energy is achieved. The current DRX configuration mode can be realized by RRC (radio resource control) configuration or MAC-CE (medium access control-control element) activation, and the method is semi-static; dynamic configuration is not supported. If parameters such as update periods or sleep times are required, the modification can be configured semi-statically, requiring a relatively long time.

In a specific embodiment of the present invention, a downlink control information DCI indication signaling is sent to a terminal; the sleep parameter or instruction and the DRX parameter or instruction are located in a preset functional domain of the DCI indication signaling.

The embodiment can dynamically indicate the terminal to sleep for energy saving, and can more flexibly realize the energy saving of the terminal; and the BWP indication domain or the resource allocation domain of the multiplexing DCI reduces the change of the existing protocol DCI format.

The base station additionally configures 4 sleep duration parameters for the terminal, which specifically include: 5, 10, 15, 20 time slots. The terminal detects the DCI, wherein a preset value of a resource allocation field (continuous allocation mode) corresponds to the sleep signaling, and specific 4 values of the resource allocation field may correspond to 4 kinds of sleep durations. Specifically, the terminal detects that the resource allocation domain corresponds to the sleep command, and the sleep time corresponding to the specific value is 10 timeslots. The terminal immediately enters sleep (in this case, the slot where the terminal is located counts 1 sleep slot, and the terminal needs to sleep for 9 additional slots); or go to sleep in the next slot of the slot where the sleep signaling is located (the terminal needs to sleep for 10 additional slots). After the dormancy is finished, the terminal detects the time slot again or performs time-frequency synchronization and other operations at BWP # 1.

For example, the terminal is attached to BWP #0, and if the terminal receives DCI in which a BWP indicator instructs the terminal to switch to BWP #1, the terminal switches to BWP #1 within a predetermined short time and performs monitoring, data reception, or data transmission. The sleep duration or DRX parameter may be configured per BWP: the bandwidth of BWP may be configured to 0 RBs (bandwidth of 0), and the BWP may be configured with a corresponding sleep duration. The bandwidth of the BWP is configured as n RBs (non-zero bandwidth), and the BWP may configure corresponding sleep duration or DRX parameters; when the terminal is switched from the source BWP to the target BWP: if the target BWP is configured with the dormancy duration, the terminal sleeps according to the configured dormancy duration; if the BWP is not configured with the specific dormancy duration, the terminal sleeps according to the preset dormancy duration; the bandwidth of the target BWP may be 0 RB (resource block) or a preset number of RBs.

Step 229, when the terminal is handed over from the source BWP to the target BWP, after a preset time period that the downlink data or the uplink data is not successfully transmitted on the target BWP, entering the DRX state according to the DRX parameter.

In step 227, for example, the terminal configures two BWPs, including: BWP1, bandwidth of 10 MHz; BWP2, bandwidth of 10 MHz; the terminal is attached to BWP1 at this time, BWP2 configures DRX parameter (DRX 2); and the terminal is switched from BWP1 to BWP2 according to the scheduling information in the DCI and enters a DRX state according to the DRX parameters of BWP 2.

In step 228, for example, the terminal configures two BWPs, including: BWP1, bandwidth of 10 MHz; BWP2, bandwidth of 10 MHz; the terminal is attached to BWP1 at this time, BWP2 configures DRX parameter (DRX 2); and the terminal switches from BWP1 to BWP2 according to the scheduling information in the DCI, performs corresponding data transmission on a target BWP (namely BWP2), and enters a DRX state by the DRX parameter of BWP2 after the current data transmission process is finished.

In step 229, for example, the terminal configures two BWPs, including: BWP1, bandwidth of 10 MHz; BWP2, bandwidth of 10 MHz; the terminal is attached to BWP1 at this time, BWP2 configures DRX parameter (DRX 2); the terminal switches from BWP1 to BWP2 according to the scheduling information in the DCI, and performs corresponding data transmission on a target BWP (namely BWP2), and the terminal enters a DRX state by the DRX parameter of BWP2 if the data is not successfully transmitted; alternatively, at this time, a timer may be started, and after the timing of the timer is over, the terminal enters the DRX state with the DRX parameters of BWP2 without successful transmission.

Accordingly, the step 22 may include:

step 230, entering a DRX state according to the DRX parameter on a source BWP; or

231, after finishing transmitting the downlink data or the uplink data on the source BWP, entering a DRX state according to the DRX parameter; or

In a wireless network, when data needs to be transmitted, a User Equipment (UE) always monitors a Physical Downlink Control Channel (PDCCH) and transmits and receives the data according to an indication message sent by a network side, which results in large power consumption of the UE and large time delay of data transmission. A Discontinuous Reception (DRX) power saving policy is introduced in the LTE system, and Media Access Control (MAC) is defined in the physical layer. According to the working state of DRX, the method is divided into Idle-DRX and Connected-DRX. In the Idle-DRX mode, the UE has no radio resource connection, mainly completes monitoring a call channel and a broadcast channel, and only needs to configure a fixed sleep cycle in order to achieve discontinuous reception. The DRX cycle in the idle mode is divided into an active period and a sleep period. In Connected-DRX mode, the UE has three states, respectively in active period, short DRX cycle (light sleep period) and long DRX cycle (deep sleep period), in active period, the UE is in power consumption mode; during the shallow and deep sleep periods, the UE is in a power saving mode.

In the above embodiment of the present invention, after the DRX state is ended, the terminal may switch to the source BWP again to perform channel detection or time-frequency synchronization, or the like, or may remain on the target BWP to perform channel detection or time-frequency synchronization, or the like.
