Problems solved by technology

When the service carried by the SeNB on the UE side has uplink data transmission requirements, if the UE cannot notify the SeNB of the uplink data transmission requirements of the UE in the SeNB in ​​time, the corresponding uplink data will not be scheduled, resulting in the uplink data not being sent in time and the transmission delay greatly Increase, decrease system and UE performance

Embodiment 1

[0103] In this embodiment, when the MeNB judges that part of the bearers of the UE supporting bearer separation need to be transferred to the SeNB according to the load and other conditions, the MeNB sends bearer separation request messages to the SeNB and the UE respectively. After receiving the MeNB Bearer Separation Request message, the SeNB allocates corresponding radio resources for the UE, which includes a dedicated preamble (dedicated preamble) configured by the SeNB for the UE, which is used for the subsequent UE to initiate a non-contention random access process on the SeNB use. The dedicated preamble configuration may be notified to the UE by the MeNB during the bearer separation process, or notified to the UE by the MeNB or SeNB in ​​the bearer separation state. The dedicated preamble may be allocated by the network to a specific cell of the SeNB, or may be allocated to all cells of the SeNB, that is, the dedicated preamble is applicable to all cells of the SeNB.

Embodiment 2

[0117] In this embodiment, the UE supporting bearer separation works under the MeNB and the SeNB at the same time, and performs data transmission and processing with the MeNB and the SeNB respectively.

[0118] When the UE has an uplink transmission requirement at the SeNB, the UE notifies the MeNB that the UE has an uplink data transmission requirement at the SeNB by reporting an indication, such as the SeNB uplink data transmission requirement indication; the MeNB notifies the UE requirement to the SeNB according to the reporting indication information, The SeNB performs CFRA or allocates UL resources. The reported instruction information can be BSR MAC CE, or new MAC CE can be imported.

[0119] Such as Figure 7 As shown, in step 701, if the UE has an uplink data transmission requirement at the SeNB, and the UE and the SeNB cell are in an uplink out-of-synchronization state or the D-SR corresponding to the SeNB is not configured or the D-SR configuration fails, and the UE...

Embodiment 3

[0125] In this embodiment, the UE supporting bearer separation works under the MeNB and the SeNB at the same time, and performs data transmission and processing with the MeNB and the SeNB respectively. The base stations supporting bearer separation each save the corresponding relationship between the cell or logical channel of the corresponding UE and the base station.

[0126] Such as Figure 8As shown, in step 801, if the UE has an uplink transmission requirement on the SeNB, and the uplink out-of-synchronization state between the UE and the SeNB cell or the D-SR corresponding to the SeNB is not configured or the D-SR configuration fails, and the UE and the MeNB cell If the UE is still in the uplink synchronization state, then in step 802, the UE sends the UE's data transmission requirement in the SeNB (such as uplink data transmission requirement indication information) through the MeNB cell. The uplink data transmission requirement indication information may be a newly de...

Abstract

The invention discloses an uplink scheduling requesting method, an uplink scheduling method and equipment. According to the uplink scheduling requesting method, the uplink scheduling method and the equipment, in a scene of multi-evolved NodeB (eNB) aggregation, particularly bearing separation, user equipment (UE) informs a secondary eNB (SeNB) cell of an uplink data transmission request in a direct manner or in an indirect master eNB (MeNB) manner to enable the SeNB cell to schedule uplink transmission of the UE on the SeNB cell according to the uplink data transmission request of the UE. The problem about scheduling of uplink data transmission through the uplink data transmission request and an uplink resource request of a network or the UE is solved, and the performances of a system and a user are ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink scheduling request method, an uplink scheduling method and equipment thereof. Background technique [0002] The network architecture of e-UTRAN (evolved Universal Terrestrial Radio Access Network, evolved Universal Terrestrial Radio Access Network) is as follows: figure 1 As shown, the E-UTRAN is composed of eNB (evolved NodeB, evolved NodeB, ie base station). The eNB completes the access network function, and communicates with the UE (User Equipment, user equipment, that is, the terminal) through the air interface. Both a control plane connection and a user plane connection exist between the UE and the eNB. For each UE attached to the network, a MME (Mobile Management Entity, mobility management entity) provides services for it, and the MME is connected to the eNB through the S1-MME interface. The S1-MME interface provides UE with control plane services, including ...
