Embodiment 1

[0220] This embodiment describes the paging information transmission process based on uplink mobility when the reciprocity between the UE and the TRP side is not established. The signaling process is as follows: Figure 4 As shown, the specific description is as follows:

[0221] Step 101, network side TRP x Send configuration information to the communication node UE, where the configuration information includes configuration information for sending uplink reference signals, configuration information for receiving feedback information, and an association relationship between uplink reference signal resources and feedback resources.

[0222] The configuration information is that after the terminal completes the initial access and enters the link state, the TRP x Message sent to the terminal. After the terminal has no data to interact with and enters the RRC_idle state or the RRC_inactive state, a mobility decision mechanism based on uplink reference signal measurement will be...

Embodiment 2

[0239] This embodiment describes the paging information transmission process based on uplink mobility when UE side reciprocity is not established and TRP side reciprocity is established, the signaling flow is as follows Figure 7 As shown, the specific description is as follows:

[0240] Step 201, network side TRP x Send configuration information to the communication node UE; the configuration information includes configuration information for sending uplink reference signals, configuration information for receiving feedback information, and an association relationship between uplink reference signal resources and feedback resources.

[0241] Step 202, the terminal sends an uplink reference signal according to the configuration information;

[0242] Step 203, TRP sends feedback information to the terminal with the preferred downlink transmission beam, the feedback information includes paging indication information, and the preferred uplink transmission beam information of the...

Embodiment 3

[0252] This embodiment describes the paging information transmission process based on uplink mobility when the UE side reciprocity is established and the TRP side reciprocity is not established, the signaling flow is as follows Figure 9 As shown, the specific description is as follows:

[0253] Step 301, network side TRP x Send configuration information to the communication node UE; the configuration information includes configuration information for sending uplink reference signals, configuration information for receiving feedback information, and an association relationship between uplink reference signal resources and feedback resources.

[0254] Step 302, the terminal sends an uplink reference signal according to the configuration information;

[0255] The transmission configuration of the uplink reference signal is the same as that in Embodiment 1, and will not be repeated here. In such a process, TRP x The UE side can identify the preferred uplink receive beam, and a...

Abstract

A paging transmission method under uplink mobility includes the following steps: enabling a communication site to receive an uplink reference signal of a communication node according to configurationinformation, wherein the configuration information includes uplink reference signal transmission configuration information and receiving configuration information of feedback information, and an association relationship between an uplink reference signal resource and a feedback resource; and sending the feedback information to the communication node, wherein the feedback information includes paging instruction information or paging information. According to the scheme, the receiving and transmission of the paging information under a mechanism based on the uplink mobility can be effectively achieved; and reciprocity state information is fully used, and the signaling overhead and delay of subsequent paging transmission can be saved.

Description

technical field [0001] Embodiments of the present invention relate to but not limited to the technical field of communication, and in particular, relate to a paging transmission method, a communication station, and a communication node under uplink mobility. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, traditional commercial communications mainly use 300MHz~3GHz Spectrum resources are extremely tense, which cannot meet the needs of future wireless communications. [0003] In future wireless communication, carrier frequencies higher than those used in the fourth-generation (4G) communication system will be used for communication, such as 28GHz, 45GHz, 70GHz, etc. This high-frequency channel has relatively low free propagation loss. Large, easily absorb...
