Definitions
- the present disclosure relates to the field of communication technologies, and in particular, to a method, a device, a network-side device, and a terminal for transmitting and receiving instruction signaling.
- the terminal In a 5G system, the terminal needs to detect a wider bandwidth and a higher rate, which leads to a larger power consumption of the terminal than Long Term Evolution (LTE); on the other hand, with the support of New Radio (NR)
- LTE Long Term Evolution
- NR New Radio
- the functions of the terminal are increased, and the terminal (User Equipment, UE) may need to support different services at different moments, resulting in the terminal's frequency of use becoming more frequent and further increasing power consumption.
- UE User Equipment
- the energy consumption of the terminal is mainly focused on two aspects:
- the terminal needs to wake up at each paging occasion (PO) to listen to the Physical Downlink Control Channel (PDCCH), but because the base station does not necessarily configure a paging message for the terminal, the terminal is at Detecting the PDCCH phase consumes a lot of energy.
- PO paging occasion
- PDCCH Physical Downlink Control Channel
- Scheduling-free PDCCH (PDCCH without grant): In a radio resource control (RRC) connected state, the terminal blindly detects the PDCCH, but does not have scheduling information of the terminal, and consumes a lot of energy.
- RRC radio resource control
- Some energy-saving solutions in related technologies include:
- WUS wake-up signal
- PAG next paging occasion
- the WUS signal uses a 131-length ZC (Zadoff-chu) sequence, which carries a cell identifier (cell ID).
- the maximum time domain duration of the WUS is configured through the upper layer, and the interval between the WUS and the PDCCH scheduling the paging message is configured gap), as shown in Figure 1.
- NB Near Band
- NB is a narrowband system, the entire bandwidth of NB is occupied in the WUS frequency domain, and one subframe is used in the time domain, that is, 1 ms.
- DRX Connected Discontinuous Reception, C-DRX
- C-DRX Connected Discontinuous Reception
- the adjustment of C-DRX is a semi-static adjustment, which is relatively slow.
- the power consumption ratio of the terminal detecting the PDCCH is quite high.
- the control channel detection supports different parameter configurations, such as different control channel detection cycles, different control channel detection candidates, etc. Although parameter adjustments can be made, they are all adjusted through high-level signaling, and the adjustment cycle is relatively long.
- the terminal manufacturers Even if a part of the energy-saving mechanism is introduced in the NR, the terminal manufacturers still believe that the power consumption of the connected state occupies most of the power consumption of the terminal.
- the main consumption of the power consumption of the connected state is that the terminal needs to blindly detect all of the power at the PDCCH detection time.
- PDCCH candidate to obtain PDCCH scheduling information but in most cases, the terminal performs a blind check, but because there is currently no actual effective uplink or downlink scheduling information, that is, the base station does not actually send the control channel, or the base station only A small part of the many possibilities of PDCCH detection was sent, and the interruption did not have any prior information, which caused the terminal to consume more power during the blind detection.
- the WUS design in NB is mainly used to solve the energy consumption problem of idle state users detecting invalid PDCCH.
- the energy saving technology of the physical layer focuses on the energy saving technology of the connected state.
- the scheduling frequency of the control channel is slot-level.
- the idle paging cycle is on the order of tens, hundreds of milliseconds.
- a slot level is added for each control channel scheduling (LTE's time-domain scheduling unit is a sub-frame, including 14 15KHz subcarrier intervals, namely Orthogonal Frequency Division Multiplexing (OFDM) symbols, NR
- the time-domain scheduling unit is a time slot or a mini-slot.
- a time slot contains 14 OFDM symbols regardless of the subcarrier interval size.
- control channel detection complexity of the NR connection state comes from various aspects, such as the frequency of detection, the number of control channel candidates detected, and the bandwidth of detection.
- the WUS design in a narrowband Internet of Things (NB-IOT) system only needs to indicate whether the PDCCH of the paging channel needs to be detected.
- connection state energy saving with DRX is configured by a high-level parameter
- the parameter adjustment is not flexible, and the energy saving effect cannot be quickly adapted to the service type of the terminal, so an optimized design is also needed.
- the WUS design in NB cannot meet the energy-saving design needs of NR's connected state.
- An object of the present disclosure is to provide a method and device for transmitting and receiving instruction signaling, a network-side device, and a terminal, so as to solve the problem that the setting of the wake-up signal in the related art cannot meet the energy-saving design requirements of the NR connection state.
