Problems solved by technology

But in this way, since there is no HARQ process (process) for paging, the UE that needs CE usually cannot receive the paging message in a paging occasion (PO), which means that the UE is unreachable (unreachable)

Embodiment Construction

[0029] Reference will now be made in detail to some embodiments of the invention, and examples of the invention will be described with reference to the accompanying drawings.

[0030] figure 1 Is a schematic diagram of a wireless communication network 100 with UEs requiring CE, according to an embodiment of the present invention. The wireless communication system 100 includes a plurality of fixed basic units, such as base stations 111-116, and base stations 121-124, forming a network distributed in geographical areas, and each base station covers a geographical area. The basic unit may also be referred to as an access point, an access terminal, a base station, a node B (Node-B), an evolved node B (eNode-B, eNB) or other words in the field. One or more base stations 111-116, and 121-124 serve a plurality of mobile stations 101, 102, and 103 in a service area, such as a cell, or a cell sector. Backhaul connections, such as X2 interfaces 131-136, connect non-co-located base st...

Abstract

Methods and apparatus are provided for paging transmission and reception for UEs requiring coverage extension / coverage enhancement. In one novel aspect, the UE reports the CE status to the MME. CE level related information and the corresponding cell ID are provided from eNB to MME. MME sends paging information including the repetition number to all eNBs in the corresponding tracking area when paging the UE. In another novel aspect, a paging area is used for CE UEs. The UE receives paging area information, notifies the network, and updates the stored paging area information upon detecting changes between the received and the stored paging areas. In another embodiment, the UE reports its CE status upon detecting CE status changes. The eNB stores UE CE information and forwards it to neighboring eNBs in the same paging area. The eNB pages UEs on its CE UE list with repetition while paging other UEs normally.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of the Chinese patent application submitted on May 9, 2014, the application number is CN201410195278.9 titled "Optimization Mechanism for Paging Transmission and Reception (OPTIMIZED MECHANISM FOR PAGING TRANSMISSION ANDRECEPTION)", the subject matter of the above application Incorporated here for reference. technical field [0003] The disclosed embodiments relate generally to wireless communications and, more specifically, to optimized mechanisms for paging transmission and reception. Background technique [0004] Widely scalable wireless communication is a challenge for all types of networks, especially in rural or remote areas. Due to the nature of the wireless environment, service and power are difficult to transfer. It is unrealizable and uneconomical to deliver coverage using traditional base station methods. Taking LTE as an example, it can be deployed on a higher carrie...
