Embodiment 1

[0104] see Figure 4 , this embodiment provides a discontinuous reception method, including:

[0105] 401: The user equipment UE in the victim cell acquires the first subframe set;

[0106] 402: The UE monitors the PDCCH and / or measures in the first set of subframes;

[0107] Wherein, the first subframe set is the subframe set obtained according to the subframe information corresponding to the activation state in the discontinuous reception DRX configuration information of the victim cell and the almost blank subframe ABS related information of the offending cell.

[0108] In this embodiment, the information related to the ABS of the offending cell includes, but is not limited to: a full set or a subset of the ABS of the offending cell. Wherein, the way of obtaining the first subframe set includes but not limited to: taking the intersection of the subframe set corresponding to the activation state in the DRX configuration information and the subframe set of the victim cell c...

Embodiment 2

[0112] see Figure 5 , this embodiment provides a discontinuous reception method, including:

[0113] 501: The victim cell sends DRX configuration information of the victim cell to the UE.

[0114] 502: The victim cell sends the subframe set of the victim cell corresponding to the full ABS set or subset of the offending cell to the UE.

[0115] Specifically, the victim cell may notify the UE of the subframe set of the victim cell through RRC (Radio Resource Control) signaling or MAC CE (Medium Access Control Control Element).

[0116] Wherein, this embodiment does not limit the sequence of 501 and 502, they can be interchanged, and can also be performed at the same time.

[0117] 503: The UE intersects the subframe set corresponding to the activation state in the received DRX configuration information and the received subframe set of the victim cell to obtain the first subframe set, and performs monitoring in the first subframe set PDCCH and / or measurements.

[0118] In th...

Embodiment 3

[0130] On the basis of Embodiment 1 or 2, this embodiment has been improved. In addition to monitoring the PDCCH and / or measuring on the first subframe set, the UE can further, according to the specified radio frame frame number AF and radio The subframe number AO of the frame is used to monitor PDCCH and / or measure, see Figure 8 , this embodiment provides the first discontinuous reception method, including:

[0131]801: The UE in the victim cell obtains the first subframe set, the detailed process is the same as that described in Embodiment 1 or 2, and will not be repeated here.

[0132] 802: The victim cell calculates the activation period T of the UE, the starting subframe position of the active state within the activation period relative to the initial subframe position of the activation period according to the UE's measurement accuracy requirements and service scheduling requirements, and the ABS information of the offending cell The offset value Tm_offset, and the dura...

Abstract

The invention provides a discontinuous reception method, user equipment (UE) and a base station which belong to the technical field of communication. The method comprises the following steps that: the UE in a harmed community acquires a first sub frame set; and the UE monitors a physical downlink control channel (PDCCH) and / or measures in the first sub frame set, wherein the first sub frame set is obtained according to the sub frame information which corresponds to an activated state in discontinuous reception (DRX) configuration information of the harmed community and relevant information of a almost blank subframe (ABS) of an invading community. The UE comprises a first acquisition module and a first processing module. According to the invention, the energy consumption of the UE and the business needs or the performance needs of the UE are effectively balanced and ensured.

Description

[0001] This application claims priority to a Chinese patent application with application number 201110003133.0 and titled "Method, User Equipment and Base Station for Discontinuous Reception" filed with the China Patent Office on January 7, 2011, the entire contents of which are hereby incorporated by reference In this application. technical field [0002] The present invention relates to the field of communication technology, in particular to a discontinuous reception method, user equipment and base station. Background technique [0003] At present, small base stations such as Pico (miniature base station), HeNB (home base station), Femto (miniature base station), and Relay (medium base station) can be placed within the coverage of LTE (Long Term Evolution, long-term evolution) Macro eNB (macro base station). Following the base station) and other wireless access points, the UE (User Equipment) is under the dual coverage of Macro eNB and small base station. The maximum capac...
