Method for selecting same-frequency interference cell list on TDD UE side

Abstract

The invention relates to a method for selecting a same-frequency interference cell list on a time division duplex user equipment (TDD UE) side. The method comprises the following steps of: generating initial same-frequency interference cell lists according to same-frequency measurement, different-frequency measurement and self-measurement results; updating the initial same-frequency interference cell lists according to same-frequency and different-frequency measurement periods; sequencing the initial same-frequency interference cell lists according to received signal code power (RSCP) measurement results, and preferably selecting the maximum same-frequency interference cell, wherein the measurement is easy to confuse with the previous measurement; selecting and configuring detection cell lists from the initial same-frequency interference cell lists in turn by using the UE; calculating an RSCP measurement value according to received service time slot data; and screening an effective interference cell which meets a set threshold.. The method can effectively acquire a practically effective same-frequency interference cell list aiming at different time slots, and can remove the influence of error interference cell configuration on a same-frequency interference elimination algorithm module.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a 3GPP LCR-TDD / 3.84McpsTDD / 7.68Mcps TDD UE side co-channel interference cancellation processing implementation Background technique [0002] According to 3GPP and CCSA related N-frequency co-frequency networking agreement, the N-frequency feature is introduced into the TD-SCDMA system. That is, each cell is configured with multiple carrier frequencies, wherein the carrier frequency carrying the P-CCPCH is the primary carrier frequency, and the carrier frequency not carrying the P-CCPCH is the secondary carrier frequency. One N-frequency cell can be configured with one main carrier frequency and N-1 auxiliary carrier frequencies. [0003] Taking the same-frequency network with 5M bandwidth and 3 frequency points as an example, in order to maximize the system capacity, each N-frequency cell is configured with one main carrier frequency and two auxiliary ca...

Therefore co-channel interference does not exist on all cells detected from the measurement results for a specific time slot

[0014] In addition, in a more complex N-frequency point network, there may be multiple cells under each frequency point. At this time, the configuration of the same-frequency and different-frequency measurement cell lists on the network side is inaccurate and non-real-time.

If only the same-frequency and different-frequency measurement results are used to select the cell, it is easy to cause missed detection of the same-frequency interference cell, which seriously affects the receiving performance
