Description

TCI state configuration method and device of energy-saving signal

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a TCI state configuration method and apparatus for an energy saving signal.

Background

In the related art, a power saving scheme for triggering a terminal through a power saving signal (power saving signal) is proposed to reduce unnecessary terminal behavior and terminal power consumption. One of the functions of the power saving signal is to indicate whether the terminal detects a Physical Downlink Control Channel (PDCCH) in an associated Discontinuous Reception (DRX) cycle.

After the energy-saving signal is introduced, the terminal first detects the energy-saving signal to determine whether to wake up for other PDCCH reception in the corresponding DRX cycle, so that the energy-saving signal must ensure high robustness. However, the energy-saving signal is a PDCCH, the PDCCH is transmitted in a control resource set (CORESET), and currently, a CORESET only has one Transmission Configuration Indication (TCI) configuration, that is, only has one beam direction, so that the energy-saving signal carried by a CORESET can be received on only one beam, and Transmission robustness of the energy-saving signal cannot be guaranteed.

The techniques described herein may be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes NR systems for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications.

The following description provides examples, and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the spirit and scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described methods may be performed in an order different than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

In a New Radio (NR), a terminal (User equipment, UE) can only perform Physical Downlink Control Channel (PDCCH) detection according to a detection position configured by a high-level signaling. However, due to the uncertainty of the packet arrival time, the UE may detect the PDCCH but not detect the scheduling Information in the Downlink Control Information (DCI), and in this case, the UE performs a useless PDCCH detection action, which consumes energy. In a scenario where Discontinuous Reception (DRX) is configured, there may be no scheduling at all in some DRX cycles. Configuration parameters of the higher layer signaling may also affect the energy consumption effect of the terminal, such as scheduling timing, multiple-Input Multiple-Output (MIMO) layer number, and so on.

Consider that in the DRX configuration scenario, there may be a situation where there is no terminal scheduling for one DRX cycle, whereas in the related art, the terminal must wake up to detect PDCCH every DRX cycle. Therefore, in the related art, one of the roles of the power saving signal is to indicate whether the terminal detects the PDCCH in the associated DRX cycle. If the terminal detects the energy-saving signal or the energy-saving signal indicates the terminal to detect the PDCCH in the corresponding DRX period, the terminal detects the PDCCH in the corresponding DRX period, otherwise, the terminal does not detect the PDCCH in the corresponding DRX period. The power-saving signal for indicating whether the terminal detects the PDCCH in the DRX cycle is a kind of downlink control channel (PDCCH), and is detected outside the active period of DRX.

Due to the introduction of multi-beams, a Transmission Configuration Indication (TCI) state is introduced in NR, which means that one or two reference signals have a quasi-co-location (QCL) relationship. The terminal receives the PDCCH, and the higher layer signaling configures one or more TCI states for a control resource set (CORESET) in which the terminal receives the PDCCH. If the higher layer signaling configures only one TCI state, the terminal assumes that the Demodulation Reference Signal (DMRS) of the received PDCCH and the Reference Signal in the configured TCI state are quasi co-located (quasi co-located). The Media Access Control (MAC) Control Element (CE) activates one of the TCI states if the higher layer signaling configures the one of the TCI states. If the terminal does not receive the MAC CE activation command, the terminal assumes that DMRS for receiving the PDCCH and a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block used for initial access are quasi co-located (quasi co-located).

After the energy-saving signal is introduced, the terminal first detects the energy-saving signal to judge whether to wake up in the corresponding DRX cycle for other PDCCH reception, so that the energy-saving signal must ensure high robustness. In NR, especially the high frequency band, the physical signals or channels are transmitted in the form of beams to improve the signal coverage, with a maximum of 8 beams at low frequencies and a maximum of 64 beams at high frequencies. Therefore, in order to ensure robust transmission of the power saving signal, the power saving signal needs to be transmitted in a beam scanning manner. Otherwise, assuming that the energy-saving signal has only one beam direction, if the terminal does not schedule for a long time, the terminal cannot detect the PDCCH and cannot perform beam management, and the optimal beam direction of the terminal has changed, so that the terminal may not detect the energy-saving signal at the time when the terminal needs to wake up. Because the terminal cannot detect the energy-saving signal, the terminal cannot enter DRX, and cannot report channel state information and beam information, and meanwhile, the base station cannot know the nearest beam direction of the terminal at the moment, which finally results in failure of a communication link. If the energy-saving signal adopts a beam scanning mode, the terminal always receives the beam direction of the strongest energy-saving signal, and the robust transmission of the energy-saving signal can be ensured.

Since the power saving signal is a PDCCH, the PDCCH is transmitted in the CORESET, and currently, a CORESET has only one TCI configuration, that is, only one beam direction. And a terminal is configured with 3 CORESET at most on a downlink Bandwidth part (BWP), even if the energy-saving signals are transmitted on the 3 CORESET, only 3 beam directions are available, which is much smaller than the requirements of 8 low-frequency beams and 64 high-frequency beams.

Currently, in NR, core set #0 for a common search space for receiving a system message, RAR and paging may be transmitted in a beam scanning manner, and a terminal receives the system message, RAR and paging PDCCH according to a beam direction of a Synchronization Signal Block (SSB) selected by initial access. Even if the UE-specific search space is transmitted on CORESET #0, the terminal can only obtain one TCI state configured for CORESET #0 by the higher layer signaling. For other CORESET, only one TCI configuration can be activated. For the energy-saving signal triggering the terminal to wake up in the DRX cycle, the search space is a search space dedicated to the UE, so that only one piece of TCI configuration information can be obtained on one core set, that is, only one energy-saving signal carried by one core set can be received on one beam.

In order to solve the above problem, embodiments of the present invention provide a method and an apparatus for configuring a TCI state of an energy saving signal, so that the energy saving signal can implement a beam scanning function, and improve transmission robustness.

An embodiment of the present invention provides a method for configuring a TCI state of a transmission configuration indication of an energy saving signal, which is applied to a network device, as shown in fig. 1, and includes:
