Description

Information processing method and device Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information processing method and device. Background Art

[0002] Rel-18 introduced a low-power (LP) wake-up signal (WUS). This LP WUS signal uses a separate receiver, called a low-power-wake-up receiver (LP-WUR). The terminal requires a main radio (MR) to properly process downlink and / or uplink data. The LP WUS signal can instruct the terminal's main radio to switch between any two sleep states, and can also instruct the terminal to wake up or not wake up the main radio.

[0003] Considering the time-frequency deviation during the operation of LP WUR, it is recommended to introduce a low power-synchronization signal (LP-SS) to assist the time-frequency synchronization during the LP WUS reception process.

The CU-DU structure can be used to split the protocol layer of the network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0125] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0127] In some embodiments, a low power (LP) wake-up signal (WUS) is introduced in Rel-18. The LP WUS signal uses a separate receiver, called a low power-wake-up receiver (LP-WUR). The terminal needs to use the main radio (MR) to process downlink and / or uplink data normally. The LP WUS signal can be used in RRC connected state (connected), inactive state (inactive), idle state (idle) and other states. The LP WUS can instruct the terminal main receiver to switch between any two sleep states, and can also instruct the terminal to wake up or not wake up the main receiver. If the terminal receives a WUS signal indicating wake-up, it will turn on the main receiver to receive and process downlink and / or uplink signals. If the WUS signal is not received, or the WUS indicates not to wake up, the UE will maintain the current sleep state of the main receiver. The sleep states of the main receiver MR include four types: ultra-deep sleep, deep sleep, light sleep, and micro sleep.

[0128] LP WUR operates in two modes: "always on" and "duty cycle." In the always on mode, the terminal's LP WUR is always on, and the base station can send an LP WUS to wake the terminal at any time. In the duty cycle mode, the terminal uses a mechanism to only turn on the LP WUR during the LP WUS listening window, and the base station can only send an LP WUS to wake the terminal during this window.

[0129] In some embodiments, considering the time-frequency deviation during the operation of the LP WUR, it is recommended to introduce a low power-synchronization signal (LP-SS) to assist in the time-frequency synchronization during the LP WUS reception process.

[0130] Optionally, there are two potential operating modes of LP-SS. One is that LP-SS is configured for each cell, that is, only one common LP-SS is configured for a cell, and all UEs synchronize their LP WUS reception by receiving the LP-SS. The other is that LP-SS is configured for each UE or UE group.

[0131] There are two potential LP-SS transmission modes: one is periodic transmission; the other is aperiodic transmission.

[0132] The purpose of LP-SS is to assist the WUR in time-frequency synchronization and obtaining the corresponding cell ID information before receiving the WUS signal. How to search for LP-SS in the frequency domain, which frequency domain resources to search on, and determining the frequency domain location of the LP-SS are issues that need to be considered.

[0133] The information processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0134] FIG2A is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information processing method for a communication system 100, the method comprising:

[0135] Step S2101: The network device 102 sends first information.

[0235] The following is an exemplary introduction to the above methods in the above embodiments.

[0236] In some embodiments, the LP-SS is placed on a synchronization grid. The synchronization grid of the LP-SS is still based on the GSCN of each frequency domain range. The definition method may include at least one of the following:

[0237] The LP-SS synchronization grid corresponds one-to-one with the global synchronization grid;

[0238] The LP-SS synchronization grid is based on the global synchronization grid and multiplies the granularity of the synchronization grid. For example, one LP-SS synchronization grid is defined for every N global synchronization grids, where N can be 2, 3, 4, etc.

[0239] The synchronization grid of the LP-SS is expanded by different multiples in each frequency band based on the global synchronization grid. The expansion multiples can be pre-agreed in a protocol or indicated through RRC signaling.

[0240] In some embodiments, to prevent LP-SS from colliding with SSB in the frequency domain, the network can instruct the WUR to search for LP-SS in a certain frequency domain range through RRC signaling or SIBX. The frequency domain range can be limited by indicating the GSCN range. The search step can be agreed upon by protocol or notified by the network as described above.

[0241] In some embodiments, the network indicates the offset between the GSCN where the LP-SS is located and the GSCN where the SSB associated with SIB1 is located, which the MR searches for, through SIBX. When the terminal enables LP-WUR, it can search for LP-SS directly at the target GSCN location based on the previous indication.
