Problems solved by technology

However, with the continuous emergence of new services, the problem that the scheduling-based access mechanism has a long access delay and cannot be reduced will become more and more obvious.
For example, from a business point of view, a large number of cloud services will be developed in the future, and the processing delay caused by the additional processing in the cloud and the increase in data transmission delay will make users more sensitive to end-to-end delay

Embodiment Construction

[0027] As mentioned above, with the emergence of new services, users will be more sensitive to the end-to-end delay of new services. Therefore, if the access delay of UE can be reduced, the processing delay of equipment can be compensated to a large extent. and data transmission delay.

[0028] In addition, from the perspective of network topology, in order to expand system capacity in the future, more and more small cells (small cells) will be added to the original macro base station. Under this topology structure, the number of UEs under the micro base station corresponding to each small cell will be much smaller than the original macro base station. If a contention-based (CB) UE access scheme is introduced on the micro base station side, the contention conflict problem will not be too obvious.

[0029] Based on the above two considerations, the present invention proposes to introduce a contention-based UE access method in a small cell. In fact, the contention-based UE acc...

Abstract

The invention discloses an access method of user equipment (UE). The access method comprises the following steps: determining the initial value of a rollback timer; determining the number of resource blocks (RBs) to be occupied by the UE; determining the rollback step length of the UE on a time domain according to the number of the RBs to be occupied by the UE, monitoring the number of idle RBs on a current channel, decreasing the numerical value of the rollback timer by one rollback step length when the monitored number of the idle RBs is greater than or equal to the number of the RBs to be occupied by the UE, and repeatedly executing the step till the rollback timer is reset; and transmitting data. Corresponding to the method, the invention further discloses an internal structure of the UE.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a user equipment (UE) access method and UE in a cellular network. Background technique [0002] A traditional cellular network is a scheduling based system. In a traditional cellular network, when the UE has data to send, the UE needs to send a scheduling request to the base station (eNB); after receiving the scheduling request, the eNB allocates uplink transmission resources for the UE, and through the dedicated control channel ( PDCCH) notifies the UE of the allocated resources. The UE can send data only after being notified of resource allocation. The above interactive process of sending a scheduling request-allocating resources-notifying resource allocation results results in at least 11 milliseconds of UE access delay in a scheduling-based system, which cannot be further reduced. Such a long access delay can meet the requirements of the system i...
