Problems solved by technology

[0002] At present, in the wireless communication system, in the process of uplink burst discontinuous low-rate service data transmission, it is only necessary to allocate a relatively small physical resource block (PRB, PhysicalResourceBlock) for the burst discontinuous low-rate service data to realize the transmission , but the allocation of too many small PRBs will cause a large number of resource fragments to the wireless communication system resources, thus reducing the resource utilization of the wireless communication system

Embodiment 1

[0083] The data transmission method provided by this embodiment, such as figure 1 shown, including the following steps:

[0084] Step 101, establishing an uplink time-domain multiplexing physical channel, and assigning a fixed PRB commonly used by all UEs to the UE in the time domain period;

[0085] Here, the base station establishes an uplink time domain multiplexing physical channel, and allocates fixed PRBs commonly used by all UEs to each UE in a time domain period.

[0086] In practical applications, the base station can allocate fixed PRBs shared by all UEs to the UE in the time domain cycle based on comprehensive consideration of its own load status and the status of each UE, such as the channel status of the UE.

[0087] Step 102: Notifying the UE of the allocated fixed PRBs commonly used by all the UEs.

[0088] Here, after the base station allocates PRBs, it notifies each UE of the allocated fixed PRBs commonly used by all UEs, so that each UE uses the fixed PRBs ...

Embodiment 2

[0104] The data transmission method provided by this embodiment, such as figure 2 shown, including the following steps:

[0105] Step 201: receiving the notified allocation of fixed PRBs commonly used by all UEs;

[0106] Here, the UE receives the allocated fixed PRBs shared by all UEs notified by the base station.

[0107] Step 202: Using the established uplink time-domain multiplexed physical channel to transmit data within the time domain period using the fixed PRB commonly used by all UEs.

[0108] Here, before performing step 202, the method may further include:

[0109] Receive a notification that a physical channel time domain multiplexing scheme is adopted;

[0110] Wherein, the UE receives the notification of adopting the physical channel time domain multiplexing scheme sent by the base station;

[0111] Specifically, the UE detects the TFM-RNTI allocated by the base station in the PDCCH until it detects the allocated TFM-RNTI; when the allocated TFM-RNTI is detect...

Embodiment 3

[0125] The data transmission method provided by this embodiment, such as Figure 4 shown, including the following steps:

[0126] Step 401: The base station establishes an uplink time-domain multiplexed physical channel, allocates a fixed PRB commonly used by all UEs to the UE in the time domain period, and notifies the UE;

[0127] Here, after the base station allocates PRBs, it notifies each UE of the allocated fixed PRBs commonly used by all UEs, so that each UE uses the fixed PRBs commonly used by all UEs to transmit data.

[0128] In practical applications, the base station can allocate fixed PRBs shared by all UEs to the UE in the time domain cycle based on comprehensive consideration of its own load status and the status of each UE, such as the channel status of the UE.

[0129] The base station may notify the UE of the allocated fixed PRBs commonly used by all UEs through a common PDCCH or broadcast signaling.

[0130] Step 402: After receiving the notification, the ...

Abstract

The invention discloses a data transmission method, comprising the steps that: a base station establishes an uplink time domain multiplexing physical channel, allocates a fixed physical resource block (PRB) shared by all UE to user equipment (UE) within a time domain period and notifies the fixed physical resource block to the UE; and after receiving the notification, the UE uses the established uplink time domain multiplexing physical channel to transmit data within the time domain period by adopting the fixed PRB shared by all UE. The invention further discloses a base station, UE and a data transmission system.

Description

technical field [0001] The present invention relates to wireless communication technology, and in particular to a data transmission method and system, a base station and user equipment (UE, User Equipment). Background technique [0002] At present, in the wireless communication system, in the process of uplink burst discontinuous low-rate service data transmission, it is only necessary to allocate a relatively small physical resource block (PRB, PhysicalResourceBlock) for the burst discontinuous low-rate service data to realize the transmission , but this allocation of too many small PRBs will cause a large number of resource fragments to the resources of the wireless communication system, thereby reducing the resource utilization rate of the wireless communication system. [0003] Therefore, how to reduce resource fragmentation in the system and improve resource utilization is an urgent problem to be solved at present. Contents of the invention [0004] In order to solve...
