Paging method, base station, and user equipment

Abstract

The embodiment of the invention discloses a paging method, a base station, and user equipment. The method includes the steps that the base station acquires a paging message of the user equipment, anddetermines at least two virtual paging frames according to the configuration information of the discontinuous reception DRX of the target of the user equipment; the base station attempts to access a channel on at least two virtual paging frames, determines one of the virtual paging frames that arrives after successfully accessing the channel as the target virtual paging frame, and sends a notification message, a downlink control message and a paging message to the user equipment by using the target virtual paging frame, wherein the notification message is used to indicate that the base stationhas successfully accessed the channel, the downlink control information carries the first paging identifier of the paged user equipment, and is used to indicate the time frequency resource location occupied by the paging message. In the embodiment of the invention, the method can increase the probability that the base station successfully accesses the channel by repeatedly attempting to access the channel, thereby reducing the paging delay of receiving the paging message of the user equipment, and improving the paging efficiency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a paging method, a base station and user equipment. Background technique [0002] With the rapid growth of smart devices, the data traffic is increasing day by day, so the network capacity needs to increase exponentially to meet the actual demand. On the one hand, the use of new technologies can increase the capacity of mobile networks; on the other hand, increasing spectrum resources can also improve network performance. However, limited and non-renewable spectrum resources are even more precious, such as license-free frequency bands. In the unlicensed frequency band, there are multiple communication systems accessing channels corresponding to the unlicensed frequency band, for example, communication systems such as Long Term Evolution (Long Term Evolution, LTE) and Wireless Fidelity (Wireless Fidelity, WIFI). The coexistence of multiple communication systems in the lice...

Problems solved by technology

However, since the base station may not successfully access the channel in the license-free frequency band, the base station does not send a paging message

For the UE, in a DRX cycle, the UE cannot detect its own P-RNTI in the PDCCH at the time corresponding to the paging subframe, and the UE will mistakenly think that the base station has no downlink data arrival and enter the DRX state again, resulting in The paging delay of the UE's downlink license-free frequency band increases, that is, the base station fails to access once, and the UE needs to wait for the next DRX, which reduces the paging efficiency
