Embodiment Construction

[0067] In order to improve the transmission gain of uplink data, in the embodiment of the present invention, for TDD uplink and downlink configurations 2, 3 and 4, a corresponding TII bundling scheme is also designed, that is, in these three cases, according to the uplink sub The number of frames, the UE will send different RVs of the same TB after channel coding on at least two uplink subframes in a bundle, so as to achieve multiple transmissions of the same uplink data, correspondingly, in these three cases, The base station also needs to receive channel-coded different RVs of the same TB sent by the UE on at least two uplink subframes in each bundle according to the number of uplink subframes in each radio frame, and decode them after combining them.

[0068] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0069] In the embodiment of the present invention, for the uplink and downlink configura...

Abstract

The invention relates to the field of communication, and discloses a method and an apparatus for transmitting uplink data, which are used for increasing the gain of uplink transmission. Aimed at cases in which uplink and downlink time slots in Time Division Depluxing (TDD) mode are configured as 2UL, 3UL and 4UL, in a Round Trip Time (RTT), an UE is permitted to adopt at least two uplink subframes to form a bundle for sending different Redundancy Versions (RV) in a same data packet, accordingly, a base station is permitted to adopt at least two uplink subframes to form a bundle for receiving the different Redundancy Versions (RV) in the same data packet, thus effectively increasing the emission power of data, enhancing the receiving quality of data, and further lifting the uplink covering effect and increasing the gain of uplink transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink data transmission method and device. Background technique [0002] In LTE (Long Term Evolution, long-term evolution) related specifications, it is stipulated that the wireless frame structure in TDD (Time Division Duplexing, time division duplex) mode is as follows: [0003] refer to figure 1 As shown, it is stipulated that each 10ms radio frame (wireless frame) includes two half-frames (half-frames), and each half-frame contains five subframes (subframes) of 1ms, and each subframe can be divided into two 0.5 ms slot (ordinary time slot) or 3 special time slots, that is, a special subframe (S) composed of DwPTS (downlink scheduling time slot), GP (protection time slot) and UpPTS (uplink scheduling time slot); among them, According to the standard, subframe 0 must be set as a downlink subframe, and its synchronization signals and broadcast signals (such as MIB (main s...
