Abstract
Embodiments of the present invention provide an information transmission method, including: determining, by a user equipment (UE), a first subframe; configuring the UE to send a first uplink signal in the first subframe; determining, by the UE, that the first uplink signal is a first type of uplink signal, where the first type of uplink signal occupies a first part of symbols of the first subframe, and the number of symbols included in the first part of symbols is less than the number of symbols included in the first subframe; and detecting, by the UE, a downlink control channel on a second part of symbols in the first subframe, where the first part of symbols and the second part of symbols do not overlap in time domain.
Claims26
An information transmission method, comprising:
- determining, by a user equipment (UE), a first subframe on a first carrier and on a second carrier respectively, wherein the first subframe on the first carrier is a special subframe including a downlink pilot timeslot, a guard period, and an uplink pilot timeslot, and wherein the first subframe on the second carrier is a downlink subframe and the first carrier and the second carrier are carriers that are configured for the UE;
- sending or receiving, by the UE, information in the first subframe of the first carrier;
- receiving, by the UE, in the first subframe of the second carrier, a physical downlink control channel (PDCCH);
- and
- skipping, by the UE, receiving a downlink data channel in the first subframe of the second carrier, wherein the time length for the PDCCH reception in the first subframe on the second carrier is equal to or less than the time length for downlink signal reception in the first subframe on the first carrier.
