Problems solved by technology

However, in the prior art, since the minimum scheduling delay of the UL grant is 4ms (the delay is used for the UE to receive and detect the UL grant and to group the PUSCH sent on the uplink resources indicated by the UL grant), when the downlink emergency When the transmission is less than 4 subframes, there is still an idle time (Gap) between the downlink burst and the scheduled uplink burst, and the UE cannot use this idle time for uplink transmission, and cannot efficiently use channel resources

Embodiment Construction

[0192] In the OFDM technology adopted by the LTE system, the minimum resource unit used for data transmission is a resource element (English: Resource Element, RE), and one RE corresponds to one OFDM symbol in the time domain and one subcarrier in the frequency domain. On this basis, a resource block (English: Resource Block, RB) is composed of multiple continuous OFDM symbols in the time domain and continuous subcarriers in the frequency domain, and the RB is a basic unit of resource scheduling. The uplink transmission of the LTE system uses a single carrier, and one RE corresponds to one single carrier frequency division multiple access (English: Single Carrier Frequency Division Multiplexing Access, SC-FDMA) symbol and one subcarrier in the frequency domain. In the uplink transmission of the LTE system, the UL grant is UE-specific control signaling, and there is a fixed timing relationship between the UL grant and the PUSCH scheduled by it. The PUSCH scheduled by the UL gran...

Abstract

The embodiment of the invention discloses an uplink information processing method and device. The method includes the following steps: terminal equipment receives first control information sent by base station equipment at a first downlink transmission time interval; the terminal equipment determines a time domain resource according to the first control information, wherein the time domain resource includes at least one uplink transmission time interval, a starting time unit of the time domain resource is later in time than the first downlink transmission time interval, and the starting time unit is the first uplink transmission time interval in the at least one uplink transmission time interval; and the terminal equipment sends data information on an uplink data channel, wherein the uplink data channel corresponds to at least one uplink transmission time interval in the time domain resource. By adopting the embodiment of the invention, the advantages of improving the utilization rateof the time domain resource and improving the processing efficiency of uplink information can be achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for processing uplink information. Background technique [0002] A Long Term Evolution (English: Long Term Evolution, LTE) system adopts an Orthogonal Frequency Division Multiplexing (English: Orthogonal Frequency Division Multiplexing, OFDM) technology. The uplink resource allocation of the LTE system takes Transmission Time Interval (Transmission Time Interval, TTI) as the granularity, and the length of one TTI is 14 OFDM symbols, that is, one subframe, and the length of one TTI is 1 ms. In the uplink transmission of the LTE system, the base station instructs the user equipment (English: User Equipment, UE) on the uplink shared channel (English: UL grant) on the corresponding uplink subframe through the uplink grant (English: UL grant) contained in the downlink control channel. Data information sent on Physical Uplink Shared Channel, PUSCH)...
