Embodiment Construction

[0059] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0060] Figure 5 It shows a schematic diagram of a method for reporting a power headroom provided by this embodiment, as shown in Figure 5 As shown, the method includes the following steps:

[0061] 101. In a dual connectivity network, the UE sends a first message to the macro base station and / or the micro base station, and the macro base station and / or the micro base station receives the first message sent by the UE. When constraining the primary cell of the micro base station When the index value of is 1, the first message includes: the maximum transmission power value (P CMAX，C ), the difference between the maximum transmission power value of the UE on each activated s...

Abstract

The invention discloses a power headroom reporting method comprising steps that a MeNB and / or a SeNB receive / receives a first message sent from UE in a double-link network; when an index value of a main cell constraining the SeNB is equal to 1, the first message includes a maximum transmission power value of the UE in each active service cell, a first power headroom value of the UE in each active service cell, a second power headroom value of the UE in the main cell of the MeNB or the SeNB; according to the first message, the MeNB adjusts maximum uplink transmission resource quantity allocated to the UE. The method may acquire the power headroom values of all active service cells and the maximum transmission power of the active service cells from the first message reported by the same UE, prevents data receiving errors, and effectively guarantees resource scheduling.

Description

technical field [0001] The invention relates to the communication field, in particular to a power headroom reporting method. Background technique [0002] Dual-connection network is a research hotspot in current wireless communication technology. The network architecture is as follows: figure 1 shown. Dual connectivity technology is introduced for scenarios where macro cells and small cells overlap and use the same or different frequencies, or only small cells are covered and the backhaul link between cells is not ideal. Dual connectivity means that the user is provided with wireless resources by multiple network nodes with unsatisfactory backhaul links. That is, the user is connected to the macro base station (MeNB for short) and the micro base station (SeNB for short) through the air interface at the same time, which means that the MeNB and the SeNB can provide services for the user at the same time. Since the user equipment (Unified Equipment, referred to as: UE) and t...
