Problems solved by technology

[0034] In order to ensure the correct completion of SPS release, at present, the LTE standard stipulates that UE (User Equipment) feedback information (ACK / NACK) is required for confirmation of uplink SPS release and downlink SPS release, and how to send feedback information for uplink SPS release, and How to send it together with the ACK / NACK feedback information of the existing downlink data, there is no related solution

Embodiment 1

[0105] For the same UE, when the resource release signaling of the uplink SPS and the resource release signaling of the downlink SPS are transmitted on the same subframe,

[0106] Only downlink SPS resource release signaling is sent, and the signaling in the downlink SPS resource release signaling indicates that both uplink SPS resources and downlink SPS resources are released at the same time, or that only downlink SPS resources are released, or that only uplink SPS resources are released H.

[0107] Downlink SPS resource release signaling includes: format0 and format1A indication signaling, continuous virtual resource block and discrete virtual resource block indication signaling, resource allocation signaling, modulation and coding mode signaling, new data indication signaling, HARQ process signal signaling, redundancy version signaling, power control signaling for PUCCH, and downlink allocation index signaling (FDD does not exist, only corresponding to TDD).

[0108] When...

Embodiment 2

[0141] The resource release signaling of the uplink SPS includes:

[0142] Format0 and format1A indication signaling, frequency hopping identification signaling, resource allocation signaling, modulation and coding mode signaling, new data indication signaling, cyclic shift amount signaling of data demodulation pilot, power control signaling for PUSCH Command, downlink allocation index indication signaling (FDD does not exist, only corresponding to TDD configuration 1-6), uplink allocation index indication signaling (FDD does not exist, only corresponding to TDD configuration 0), CQI trigger signaling.

[0143] When the resource release signaling of the uplink SPS indicates that the resources of the uplink SPS are released, each signaling is set as follows:

[0144] format0 and format1A indicate that the signaling is set to 0;

[0145] The frequency hopping identification signaling is set to 1;

[0146] Resource allocation signaling is all set to 1;

[0147] The modulation ...

Embodiment 3

[0156] In a TDD system, if the downlink feedback window contains an uplink SPS release subframe, the PDCCH of the subframe carries the uplink SPS resource release signaling, and the DCIformat 0 corresponding to the PDCCH of the subframe (the uplink SPS resource release signaling corresponds to The downlink allocation index indication signaling in DCI format 0) is the total number of PDSCH and SPS release subframes scheduled to the user terminal within the downlink feedback window; or, the downlink allocation index indication signaling in the DCI format 0 is downlink feedback The number of PDCCHs corresponding to the PDSCHs allocated to the user terminal (UE) within the window.

[0157] In a TDD system, if there is a downlink SPS release subframe in the downlink feedback window, the PDCCH of the subframe carries the downlink SPS resource release signaling, and the downlink allocation index in the PDCCH indicates that the signaling has been allocated in the downlink feedback wind...

Abstract

The invention provides a method for transmitting feedback information released by uplink semi-persistent scheduling (SPS), wherein the feedback information of resource release signaling of the uplink SPS, as the feedback information of the physical downlink shared channel, is processed. The invention also provides a method for transmitting feedback information released by SPS, wherein for the same one user terminal, when the resource release signaling of the uplink SPS and the resource release signaling of the downlink SPS are transmitted on the same sub-frame, the sub-frame transmits the resource release signaling of only one type of SPS, and the feedback information of the resource release signaling of the transmitted SPS, as the feedback information of the physical downlink shared channel, is processed. The method for transmitting feedback information released by uplink SPS solves the transmission problem of the feedback information released by uplink SPS and solves the problem of compatibility with the acknowledgement / negative acknowledgement (ACK / NACK) feedback information of existing downlink data, thereby ensuring the receiving stat of the resource release signaling of the uplink SPS, preventing the extra interference and unnecessary decoding error, and further ensuring the system performance.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for sending feedback information for uplink semi-persistent scheduling release. Background technique [0002] The Long Term Evolution (LTE for short) system is an important plan of the third generation partnership organization. figure 1 shows a schematic structural diagram of a basic frame structure in an LTE system, such as figure 1 As shown, the frame structure is divided into five levels: radio frame, half frame, subframe, time slot and symbol. Among them, the length of a radio frame is 10ms, and a radio frame is composed of two half frames. The length is 5ms, one half frame is composed of 5 subframes, each subframe is 1ms long, and one subframe is composed of two time slots, each time slot is 0.5ms long. [0003] When the LTE system adopts the normal cyclic prefix, one time slot contains 7 symbols, and when the LTE system adopts the extended cyclic prefix, one time slot c...
