Abstract

The embodiment of the invention provides a method for providing downlink control information used for carrying out uplink transmission for two- antenna and four-antenna mobile terminals in management equipment enhancing a long-term evolution network. The method comprises the following steps of: determining an uplink transmission mode for the two- antenna mobile terminal; semi-statically configuring the uplink transmission mode attributive to the uplink transmission mode through high-rise signalling; generating the downlink control information which corresponds to the determined uplink transmission mode, wherein the downlink control information includes a first identifier field, a second identifier field, a new data identifier field of a first transmission block and a new data identifier field of a second transmission block; when the determined uplink transmission mode is a transmission block disabled function, forming a first combination through the values of the first identifier field and the second identifier field to express that at least one of the two transmission blocks is disabled; expressing the disabled transmission block of the two transmission blocks through a combination formed by a new data identifier of the first transmission block and a new data identifier of the second transmission block; and transmitting the generated downlink control information to the two- antenna mobile terminal.

Description

technical field [0001] The present invention relates to the control of the uplink transmission of the user terminal, in particular to the method and device for controlling the uplink transmission in the management equipment of enhanced long term evolution. Background technique [0002] In order to support the new features of Uplink Single User Multiple Input Multiple Output (SU-MIMO), Discontinuous Resource Allocation (RA) and Carrier Aggregation (CA) in Enhanced Long Term Evolution (LTE-A) Rel-10, the uplink transmission mode needs to be defined And design the downlink control information format (DCI format) of the uplink grant (UL grant), which especially involves the control of signaling overhead and blind decoding complexity. [0003] In the recent standardization meeting, regarding the above three characteristics, the following consensus was reached: [0004] 1. Uplink and downlink transmission modes can be configured independently of each other. [0005] 2. About dis...
