A method and device for detecting a Physical Downlink Control Channel, PDCCH, are provided. According to an embodiment of the present invention, the method for detecting a PDCCH at a UE includes: receiving () a configuration of an Enhanced-PDCCH, E-PDCCH; receiving () a subframe; determining () whether the received subframe is a Multimedia Broadcast Multicast Service Single Frequency Network, MBSFN, subframe; and according to a determination result, detecting () the PDCCH, where if the received subframe is an MBSFN subframe, a common PDCCH in the MBSFN subframe is detected, and if the received subframe is a non-MBSFN subframe, an E-PDCCH in the non-MBSFN subframe is detected.

Physical downlink control channel detection method and device

An objective of the present invention is to provide a method, apparatus, and equipment for determining device channel resources of a user equipment in an LTE-TDD system. The TDD system performs resource scheduling to the user equipment using an enhanced physical downlink control channel, and a physical uplink control channel used includes channel resource(s) for feeding back a hybrid automatic repeat request of a physical downlink shared channel as scheduled by the enhanced physical downlink control channel, when the number of downlink subframes as fed back in one uplink subframe may be more than one, the channel resource(s) is divided into a plurality of channel regions based on the number of downlink subframes having the enhanced physical downlink control channel set thereon currently, or based on the potential highest number of downlink subframes having the enhanced physical downlink control channel set thereon. The present application obtains the device channel resource(s) occupied by the present user equipment in at least one channel region of the plurality of channel regions. The present invention enables the user equipment to feed back ePDCCH.

Method, apparatus and equipment for determining device channel resource(s) of a user equipment

The invention relates to a method, in a wireless communication System, of determining the position, of acknowledgment/non-acknowledgment information for a hybrid automatic repeat request, in a physical uplink control channel, wherein the user equipment sends in an uplink sub-frame the acknowledgment/non-acknowledgment information for one or more downlink sub-frames. In an aspect of the invention, the base station sends to the user equipment a first starting position related to each ePDCCH set, a first offset related to a mapping relationship between the uplink sub-frame and information about the number of enhanced control channel &#xe9;l&#xe9;ments per ePDCCH set. The user equipment d&#xe9;termines the position, of the acknowledgment/non-acknowledgment information for the hybrid automatic repeat request, in the physical uplink control channel upon r&#xe9;ception of the foregoing information. With the inventive solution, a waste of physical uplink control channel resources can be lowered and full use of the resources can be made to thereby improve the efficiency of the System.

Method of determining position of acknowledgement information for HARQ in PUCCH

An antenna system and a method for reporting enhanced Reference Signal Receiving Power (eRSRP) of the same are provided. According to an embodiment of the present invention, the method for reporting eRSRP includes: transmitting, by an evolved Node Base (eNB), different reference signals to different transport points being distributed; measuring, by a user equipment (UE), eRSRP of the different transport points; and reporting, by the UE, the measured eRSRP of the different transport points to the eNB. Compared with the prior art, the eNB can obtain channel information of path loss of each transport point, to fundamentally solve the problem of unbalanced power, and can perform other optimization operations based on the information to improve the system throughput and other performance.

Antenna system and method for reporting receiving power of the same

The present invention discloses a method for determining a Physical Uplink Control Channel PUCCH resource for a user equipment and a corresponding user equipment, and a method for facilitating the determination of a PUCCH resource for a user equipment and a corresponding base station, wherein the PUCCH resource is used to transmit a Hybrid Automatic Repeat Request HARQ feed back (ACK or NACK) of the user equipment with respect to its corresponding Physical Downlink Shared Channel PDSCH. In the present invention, an index value for a Control Channel Element CCE scheduled for the user equipment in an Enhanced Physical Downlink Control Channel E-PDCCH is firstly acquired, and then based on the index value and a first parameter, the PUCCH resource used to transmit the HARQ feedback of the user equipment with respect to its corresponding PDSCH is determined, the first parameter representing a reference value that should be used when determining the PUCCH resource used to transmit the HARQ feedback of the user equipment with respect to its corresponding PDSCH, if scheduling the CCE for the user equipment in the E-PDCCH.
