Problems solved by technology

[0011] For interactive services with a small amount of data, such as QQ chat, etc., if data transmission is realized through random access and allocation of PUCCH, the online activation process will be frequently triggered, resulting in ping-pong PUCCH resource allocation.
Due to too many users in the cell, there will be no PUCCH resource allocation for online users

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] In the embodiment of the present invention, the user and the base station perform uplink synchronization through message 1, message 2, message 3 and message 4 during the uplink synchronization process. Make full use of the message 3 sent by the UE to the eNB during the uplink synchronization process. Due to the small amount of data, the user's uplink data is carried in the message 3, instead of using the PUCCH resource to apply for uplink resources to transmit the user's uplink data. Furthermore, it is avoided that the characteristic of the interactive service with a small amount of data causes PUCCH resource ping-pong switching.

[0036] See attached figure 1 It is a schematic flow chart of a data transmission method, specifi...

Abstract

A data transmission method, the method comprising: when an online user transmits uplink data, assigning a fixed resource authorization to the uplink data including the group A preamble, and assigning a resource authorization to the uplink data including the group B preamble according to existing resources ; The message sent by the terminal to the base station on the resource authorization carries the cell wireless network temporary identifier C-RNTI and uplink data; the base station determines that the reason for the online user to enter the online state according to the C-RNTI is that there is no data transmission, and the received message carries uplink data. After applying the embodiment of the present invention, the data transmission can be realized quickly by using the message to transmit data, and the frequent online reactivation process of interactive services with small data volumes can be avoided, resulting in ping-pong allocation of PUCCH resources.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to a data transmission method. Background technique [0002] During data transmission, if the terminal is in the uplink synchronization state, the network considers the user to be in the active state and belong to the active user. Activated users can use physical uplink control channel (PUCCH) resources to apply for uplink scheduling resources at any time for data transmission. If the terminal is in the uplink out-of-sync state, the network considers that the user is in the online state and belongs to the connected online user. An online user is defined as an out-of-link uplink with an RRC connection and no PUCCH / uplink listening reference signal SRS resources. [0003] The main scenarios for converting a currently active user to an online user include situations where the TA timer expires or the SR reaches the maximum number of transmissions. When the c...
