Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] The basic idea of ​​the present invention is: when the feedback end cannot directly transmit the physical channel resource information (RUs) to the sending end, the sending end and the feedback end jointly agree on a reference RUs; , the feedback information will be generated based on the reference RUs; after receiving the feedback information, the sending end will convert the feedback information based on the reference RUs into the channel state information of the actually sent RUs.

[0040] The method for measuring and feeding back channel state information for high-speed downlink packet access described in this embodiment involves a sending end, a feedback end, and a high-level entity. In this embodiment, the high-level entity is a radio network controller (RNC), the sending end is a Node B (Node B), and the feedback end is ...

Abstract

The invention discloses a feedback and treatment method of a high speed down grouping access channel information, wherein a feedback terminal need not store a great number of dependances, comprising the steps: (a) the feedback terminal obtains SINR by measuring trainning sequence code MID of HS-PDSCH, obtains recommendatory TBS / MF combination value with a preferred throughput by using a reference physical channel resource information RUs pre-promised to a sending terminal and an obtained SINR to inquire an optimal channel state option table, and transmits the recommendatory TBS / MF combination value to the sending terminal; (b) the sending terminal ensures dispatches the feedback terminal, determines a new RUs value, and obtains SINR measured by the feedback terminal by using the received recommendatory TBS / MF combination value and the reference physical channel resource information RUs pre-promised to inquire an optimal channel state option table, and then inquires an optimal channel state option table of the SINR and new RUs to re-determine TBS and MF.

Description

technical field [0001] The invention relates to a feedback processing method of channel state information, in particular to a feedback and processing method of high-speed downlink packet access channel state information in the communication field. Background technique [0002] 3GPP introduced the High Speed ​​Downlink Packet Access (HSDPA for short) feature in Releases 5 of the 3G specification, with the purpose of providing a higher rate downlink packet service and increasing downlink capacity. Based on the UMTSR4 architecture, HSDPA achieves the above objectives by introducing technologies such as Adaptive Modulation and Coding (AMC for short), Hybrid Automatic Retransmission Request (HARQ for short), and the like. [0003] Due to the constraints of the existing 3GPP network architecture, the HSDPA system improves spectrum utilization through two aspects: fast link self-adaptation and reduced network processing delay. From the perspective of link adaptation, AMC technolog...
