Embodiment 1

[0090] Embodiment 1: The UE needs to obtain synchronization through the SSB before receiving the energy-saving signal.

[0091] Step 1: The UE determines the time to monitor the paging and energy saving signals through the broadcast parameters of the system information and the UE ID.

[0092] Step 2: The UE first acquires synchronization by reading the SSB and obtains the SSB index to determine to receive the beam.

[0093] Step 3: If the base station broadcasts the energy-saving signal at the corresponding moment. The base station broadcasts energy-saving signals on each beam.

[0094] Step 4: The UE determines the time window for receiving the energy-saving signal according to the SSB index, and receives the energy-saving signal at the corresponding time.

[0095] Step 5: The base station sends the paging DCI and the paging message at the corresponding paging time.

[0096] Step 6: The UE judges whether there is a paging message to be sent through the energy saving signal...

Embodiment 2

[0099] Embodiment 2: The UE has not lost synchronization before listening to the energy-saving signal, and the energy-saving signal can determine to receive the beam.

[0100] Step 1: The UE determines the time to monitor the paging and energy saving signals through the broadcast parameters of the system information and the UE ID.

[0101] Step 2: If the base station broadcasts the energy-saving signal at the corresponding moment. The base station broadcasts energy-saving signals on each beam.

[0102] Step 3: The UE tries to receive the energy-saving signal of each beam at the corresponding time of monitoring the energy-saving signal, and determines the receiving beam and / or determines the corresponding SSB according to the receiving time of the received energy-saving signal or the carried SSB index identifier or beam identifier index.

[0103] Step 4: The base station sends the paging DCI and the paging message at the corresponding paging time.

[0104] Step 5: The UE jud...

Embodiment 3

[0107] Embodiment 3: The UE can obtain synchronization through the energy-saving signal, and the energy-saving signal can determine to receive the beam.

[0108] Step 1: The UE determines the time to monitor the paging and energy saving signals through the broadcast parameters of the system information and the UE ID.

[0109] Step 2: If the base station broadcasts the energy-saving signal at the corresponding moment. The base station broadcasts energy-saving signals on each beam.

[0110] Step 3: The UE tries to receive the energy-saving signal of each beam at the corresponding energy-saving signal monitoring time, realizes synchronization by receiving the energy-saving signal, and determines the received beam and / or by the receiving time of the received energy-saving signal or the carried SSB index or beam identifier Or determine the corresponding SSB index.

[0111] Step 4: The base station sends the paging DCI and the paging message at the corresponding paging time.

Abstract

The invention discloses a method and a device for monitoring paging in a multi-beam scene, which are used for providing a solution of how to monitor a paging message by UE in a scene of introducing anenergy-saving signal. According to the embodiment of the invention, the method comprises the following steps: receiving an energy-saving signal; and performing monitoring paging processing based on the energy-saving signal.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for monitoring paging in a multi-beam scenario. Background technique [0002] Unlike the Long Term Evolution (LTE) technology, the New Radio Technology (NR) system supports multi-beam operation. When there is a paging (paging) message to be sent, the network side does not know the idle (idle) state and the inactive (inactive) state. The range of the beam (beam) where the user equipment (UE) is located, so that the paging message cannot be sent only on a specific beam to page the UE, but the same paging message will be repeatedly sent on each beam, that is, beam sweeping (beam sweeping), to achieve full coverage. According to the UE ID, the paging cycle, and the paging parameters configured by the network, the UE can obtain the radio frame for monitoring paging and the start position of the beam sweeping paging moment. In order to avoid...
