METHODS FOR TRANSMITTING AND RECEIVING CONTROL CHANNEL, BASE STATION, AND USER EQUIPMENT

摘要

Embodiments of the present invention provide methods for transmitting and receiving a control channel, a base station, and a user equipment, which relate to the communication field, and can solve a transmission problem of available changing transmission resources caused by introduction of an E-PDCCH. A method for configuring a control channel resource includes: determining, by a base station according to a system configuration and/or user configuration, resource elements REs included in an extended control channel element E-CCE, and transmitting an extended physical downlink control channel E-PDCCH to a user equipment, where the E-PDCCH is carried by the E-CCE; and receiving, by the user equipment, the E-PDCCH, and obtaining the REs included in the E-CCE, and receiving, over the REs included in the E-CCE, the E-PDCCH transmitted by the base station. The embodiments of the present invention are used for configuring and detecting a control channel resource.

主权项

1. A method for receiving a control channel, the method comprising:
determining, by a terminal device, a resource set and resource elements (REs) of predetermined overheads in the resource set, wherein the REs of the predetermined overheads comprise a RE of a channel state information-reference signal (CSI-RS), a RE of a cell-specific reference signal (CRS), a RE of a demodulation reference signal (DMRS), and a RE of a muted RE, and a RE of at least one of a paging channel and a synchronization channel; and receiving, by the terminal device from a base station, an extended physical downlink control channel (E-PDCCH) on REs comprised in an extended control channel element (E-CCE), wherein the E-CCE carries the E-PDCCH, the REs comprised in the E-CCE are a part of the REs in the resource set and do not contain the REs of the predetermined overheads.
