Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communication technology, and in particular to a transmission control method and device. Background Art

[0002] In dual connectivity, resources of two network nodes (access network elements) may be provided to a terminal (eg, user equipment (UE)), one of which is called a master node (MN) and the other is called a secondary node (SN).

[0003] At each network node, carrier aggregation (CA) is used, that is, a series of service cells controlled by the node are configured for the UE, also known as a cell group (CG). The cell group controlled by the MN is the master cell group (MCG), and the cell group controlled by the auxiliary node is the secondary cell group (SCG). Each cell group contains a special cell (SpCell) and a series of secondary cells (Scell). In the MCG, the special cell is called the primary cell (PCell), and in the SCG, the special cell is called the primary secondary cell (PSCell). In a cell group, the SpCell uses the main carrier, while other secondary cells use the secondary carrier. Resource scheduling within a cell group is performed by the SpCell.

[0004] In the dual-connection uplink power sharing mechanism, the UE needs to adjust its uplink transmission power in the MCG or SCG to ensure that when the uplink transmissions of the MCG and SCG are carried out simultaneously, the sum of the two does not exceed the maximum uplink transmission power of the terminal. However, the network side does not know the uplink transmission power in the MCG or SCG used by the terminal during the adjustment process, and thus cannot perform transmission control accordingly. Summary of the invention

[0005] One purpose of an embodiment of the present invention is to provide a method and device for transmission control to solve the problem that the network side is unaware of the uplink transmission power in the MCG or SCG used by the terminal during the adjustment process and is unable to perform transmission control accordingly.

[0027] To facilitate understanding of the embodiments of the present invention, the following technical points are introduced below:

[0028] (1) Main scenarios of DC / CA:

[0029] Based on the different wireless access technologies and core network types, DC scenarios can be divided into the following categories:

[0030] When the core network is an Evolved Packet Core (EPC):

[0031] EN-DC (EUTRA-NR Dual Connection) is a multi-mode dual connectivity (MR-DC) architecture with an evolved Node B (eNB) as the MN and an EN-gNB (a fifth generation (5G) base station connected to the fourth generation (4G) core network under the non-independent networking architecture of the Option 3 series, called en-gNB) as the SN.

[0032] When the core network is a 5G core network (5G Core, 5GC):

[0033] New Radio Dual Connectivity (NR-DC), MR-DC architecture with gNB as MN and gNB as SN;

[0034] 5G NR and 4G radio access network dual connectivity (NE-DC), multi-mode dual connectivity (MR-DC) architecture with gNB as MN and next generation base station (NextGeneration eNodeB, NG-eNB) as SN;

[0035] Dual connectivity (NGEN-DC) between 4G radio access network and 5G NR under the 5G core network, MR-DC architecture with NG-eNB as MN and gNB as SN;

[0036] (2) Dual connection uplink power sharing mechanism:

[0037] In NR-DC, assuming that the UE maximum uplink transmission power (P total ) is certain, when the uplink transmission of the primary cell group MCG and the uplink transmission of the secondary cell group SCG occur simultaneously (i.e. overlap, specifically, the uplink transmission of any serving cell in the MCG and the uplink transmission of any serving cell in the SCG occur simultaneously), the UE needs to adjust the uplink transmission power of the MCG or SCG to ensure that the sum of the two does not exceed P total .

[0038] Assume that the UE starts SCG uplink transmission at time T0, and the SCG uplink transmission power is represented by pwr_SCG. The UE calculates pwr_SCG at time T0 according to the following method:

[0039] Before time T0-T_offset, the UE monitors the Physical Downlink Control Channel (PDCCH) of the MCG:

[0040] ■ If the PDCCH triggers / indicates that the UE has an MCG uplink transmission that overlaps with the SCG uplink transmission at time T0, the UE's SCG uplink transmission power should satisfy pwr_SCG<=min{P SCG ,P total –MCG tx power}; where P total is the maximum uplink transmission power of UE, P SCG is the maximum uplink transmission power of SCG, MCG tx power is the uplink transmission power of MCG;

[0041] ■ Otherwise, pwr_SCG <= P total ;

[0042] After T0-T_offset, the UE does not want the PDCCH of the MCG to schedule the UE to perform MCG uplink transmission that overlaps with the SCG uplink transmission at time T0.

[0043] Among them, T_offset is the time offset used by the UE in the uplink power sharing mechanism. The following describes the value of T_offset:

[0044] The current value of T_offset is in is the maximum preparation time of UE in MCG, The maximum preparation time of the UE in the SCG. The value of T proc,2 ,T proc,CSI , and / or The maximum value in; When "Without look-ahead", The value of T proc,2 ,T proc,CSI , and / or The maximum value in .

[0045] Explanation of the above parameters:

[0046] ■T proc,2Physical Uplink Shared Channel (PUSCH) processing time of the terminal in MCG or SCG;

[0047] It should be noted that processing time can be understood as preparation time, processing time, preparation delay or processing delay, etc.

[0048] ■T proc,CSI Preparation time for the terminal's channel state information (CSI) in MCG or SCG;

[0049] ■ The SPS PDSCH release preparation time when the PUSCH or PUCCH for sending SPS PDSCH release on the MCG or SCG is multiplexed with other PUCCH and / or PUSCH;

[0050] ■ It is the PUSCH preparation time of the terminal when the PUSCH of MCG or SCG is multiplexed with PUCCH and / or other PUSCH;

[0051] ■ It is the CSI preparation time when the PUSCH or PUCCH on which the terminal sends CSI on the MCG or SCG is multiplexed with other PUCCH or PUSCH.

[0052] In the process of implementing the present invention, the prior art has the following problems:

[0053] 1) The UE can calculate the above-mentioned and Then T_offset is obtained. Since there is a certain risk when MN schedules UE during [T0-T_offset, T0] (UE may not monitor the uplink scheduling of MN during this period), it is understandable that during [T0-T_offset, T0], if MCG chooses not to schedule UE, there will be a certain loss, and the larger the value of T_offset, the greater the loss of MCG's uplink transmission.

[0054] When the SN configures the SCG configuration for the UE, there are two ways to transmit it to the UE:

[0055] Mode 1: Transmitted to UE via MN SRB1;

[0056] Mode 2: SN is transmitted to UE via SRB3.

[0057] In mode 1, when MN transmits SCG configuration information, it can obtain the same acquisition method as UE. and And T_offset.

[0058] In method 2, the MN cannot obtain the SCG configuration and thus cannot calculate and And T_offset.

[0059] 2) Since the UE needs to monitor the PDCCH of the MCG before time T0-T_offset to determine whether there is overlap transmission, if so, it is necessary to prioritize the uplink transmission power of the MCG and adjust the uplink transmission power of the SCG.
