TRANSMITTED PRECODING INDICATOR COMBINING METHOD, TERMINAL AND NETWORK-SIDE DEVICE

摘要

Embodiments of the present invention relate to a precoding indicator combining method, a terminal and a network-side device. The method includes: receiving, by a terminal and from a network-side device, an offset position of a downlink fractional dedicated physical channel F-DPCH or a downlink dedicated physical channel DPCH of at least one cell, and an offset position of a downlink fractional transmitted precoding indicator channel F-TPICH of at least one cell; and determining, by the terminal, a transmitted precoding indicator TPI combining window of the cell, so that an effective position of a TPI is located at a timeslot boundary of the first uplink dedicated physical control channel DPCCH after an end boundary of the TPI combining window, thereby enabling a UE to use a timely TPI and improving demodulation performance of the UE for sending data.

1. A transmitted precoding indicator combining method, comprising:
receiving, by a terminal and from a network-side device, an offset position of a downlink fractional dedicated physical channel F-DPCH or a downlink dedicated physical channel DPCH of at least one cell, and an offset position of a downlink fractional transmitted precoding indicator channel F-TPICH of the at least one cell, wherein the offset position of the downlink F-DPCH or the offset position of the downlink DPCH is a hysteresis time from a start position of the downlink F-DPCH or a start position of the downlink DPCH to a frame start position of a former downlink P-CCPCH in a time length of two primary common control physical channel P-CCPCH frames, and the offset position of the downlink F-TPICH is a hysteresis time from a start position of the downlink F-TPICH to the frame start position of the former downlink P-CCPCH in a time length of two P-CCPCH frames; and determining, by the terminal according to the offset position of the downlink F-DPCH or the offset position of the downlink DPCH and the offset position of the downlink F-TPICH of each cell, a transmitted precoding indicator TPI combining window of the cell, so that an effective position of a TPI is located at a timeslot boundary of the first uplink dedicated physical control channel DPCCH after an end boundary of the TPI combining window.
