Embodiment Construction

[0053] 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.

[0054] Currently, 3GPP discusses and determines that in dual connectivity, a PHRMACCE format is used to report PH information of all serving cells. The PUCCH resources in the SeNB need to be configured. In the carrier aggregation scenario, if the network configures PUCCH and PUSCH to be reported simultaneously, the UE needs to report the Type 2 PH value of the PCell. Similarly, in the dual connectivity scenario, if both the SeNB and the MeNB may be configured to report the PUCCH and the PUSCH simultaneously, then the UE needs to report the Type 2 PH values ​​of the PCell and PSCell. If the MeNB and the SeNB do not know whether the other party configures the UE to report PUC...

Abstract

The invention discloses an obtaining method for a power headroom and a macro eNB (MeNB). The method comprises: an MeNB sends a re-configuration message carrying a power headroom reporting parameter to UE, so that the UE reports power headroom information of all service cells according to the power headroom reporting parameter when a power headroom reporting condition is met; the MeNB receives an MAC PDU including the power headroom information, wherein the MAC PDU includes an MAC sub head and an MAC SDU, and a second bit value in the MAC sub head or a value of a main cell index indication area of an SeNB in the MAC SDU is obtained; and the MeNB obtains power headroom information of all service cells according to the second bit value of the MAC sub head or the value of the main cell index indication area of the SeNB in the MAC SDU. With the method, the MeNB and the SeNB can obtain power headroom values and maximum transmission powers of all service cells in the dual-connection network; a problem of a data receiving error can be solved; and the resource scheduling can be guaranteed effectively.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power headroom acquisition method and a macro base station. 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 E...
