Embodiment Construction

[0053] The specific embodiments of the invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0054] At present, 3GPP discusses and determines that a PHR MAC CE format is adopted to report PH information of all serving cells in dual connectivity. The PSCell in the SeNB needs to be configured with PUCCH resources. In the carrier aggregation scenario, if the network is configured to report PUCCH and PUSCH at the same time, the UE needs to report the Type 2 PH value of the PCell. Similarly, in a dual connectivity scenario, if both the SeNB and the MeNB may be configured to report PUCCH and PUSCH at the same time, the UE needs to report the Type 2 PH value of the PCell and PSCell. If the MeNB and the SeNB do not obtain whether the other party has configured PUCCH and PUS...

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 field of communication, in particular to a method for acquiring power headroom and a macro base station. Background technique [0002] Dual-connection network is the current research hotspot of wireless communication technology. The network architecture is as figure 1 Shown. For scenarios where the macro cell and the small cell overlap and use the same / different frequencies, or there is only a small cell coverage, and the backhaul link between the cells is not ideal, dual connectivity technology is introduced. Dual connectivity means that users are provided with wireless resources by multiple network nodes with unsatisfactory backhaul links. That is, the user has air interface connections with the macro base station (abbreviated as: MeNB) and micro base station (abbreviated as: SeNB) at the same time, which means that the MeNB and SeNB can provide services for the user at the same time. Because user equipment (Unified ...
