Synchronous control method of absolute authorization value and channel state parameter and relevant equipment

Abstract

The embodiment of the invention discloses a synchronous control method of an absolute authorization value and a channel state parameter and relevant equipment. The method comprises the steps of calculating a target system frame number and a target subframe number of a channel state parameter in a target channel through a delayed sending offset value introducing the channel state parameter, a timing offset value of the frame of a target channel relative to the frame of a main public control physical channel, and a system frame number and a subframe number of an enhanced special channel absolute authorization channel subframe where an absolute authorization value to be sent to a UE exists, and sending the channel state parameter on the subframe indicated by the target system frame number and the target subframe number of the target channel. As the delayed sending offset value introducing the channel state parameter is low, the transmission delay difference between the target channel and the enhanced special channel absolute authorization channel is reduced, and the synchronous property of the absolute authorization value and the channel state parameter is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a synchronization control method and related equipment of an absolute authorization value and a channel state parameter. Background technique [0002] The Third Generation Partnership Project (3GPP, Third Generation Partnership Project) plans to introduce multiple input multiple Output (MIMO, Multiple Input Multiple Output) technology, hereinafter referred to as uplink MIMO. In uplink MIMO, the user equipment (UE, User Equipment) transmits one data block to the base station in the same transmission time interval (TTI, Transmission Timing Interval), which is called single-stream transmission; the UE transmits two data blocks to the base station in the same TTI. A data block is called a dual-stream transmission, and two data streams in a dual-stream transmission are called a main stream and a secondary stream, respectively. The mainstream is transmitted on the enhanced ded...

Problems solved by technology

Since there is a certain difference between E-AGCH and the channel, and the decoding speed of the UE on the channel state parameters is faster than that of the AG, the above scheduling scheme cannot guarantee that the UE can synchronously resolve the The issued AG and the above channel state parameters, and when the UE switches from single-stream transmission to dual-stream transmission or from dual-stream transmission to single-stream transmission, the AG may undergo a large-scale change. If the UE cannot synchronously analyze the The above-mentioned channel state parameters and AG issued by the base station may have the following two situations: UE first parses out the above-mentioned channel state parameters, and determines whether to use single-stream transmission or dual-stream transmission according to the above-mentioned channel state parameters, and then uses the previous scheduling to resolve to The AG calculates the maximum transmission power of the transmission stream (such as a single stream, or a main stream and auxiliary stream); or, the UE first parses out the AG, based on the AG and the transmission mode determined in the previous scheduling (that is, single-stream transmission or dual-stream transmission) to calculate the maximum transmit power of the transport stream

Regardless of the above situations, it may increase the uplink interference level of the cell or affect the uplink transmission efficiency of the UE.
