METHOD FOR UE AND USER EQUIPMENT

摘要

The disclosure is related to a method used in a user equipment and a user equipment thereof. The UE determines an initialization value of of a scrambling sequence generator in step 1, wherein the initialization value is determined by one or more of a first ID, a second ID and a time slot index; generates a D2D scrambling sequence in step 2; and performs a scrambling operation on a D2D signal by using the D2D scrambling sequence and transmits the D2D signal performed by the scrambling operation. In one embodiment, the second ID is one element in an integer set from 504 to 3080. In the disclosure, the UE performing D2D communication is capable to reuse a formula generating the initialization value of the current PUSCH scrambling sequence generator and the base station is capable to distinguish the D2D signal and the uplink data at the same, so as to avoid occurrence of the severe interference due to the same cell physical ID. The disclosure is capable to support the UE performing D2D communication inside or outside the cell coverage at the same time.

主权项

1. A method used in an user equipment (UE), comprising:
A. determining an initialization value of a scrambling sequence generator, wherein the initialization value is determined by at least one of the following:
a first ID;a second ID; anda time slot index; B. generating a D2D scrambling sequence; and C. performing a scrambling operation on a D2D signal by using the D2D scrambling sequence; wherein the first ID is one element in an integer set from 0 to 65535, the second ID is one element in an integer set from 504 to 3080, and the time slot index is one element in an integer set from 0 to 19; wherein the initialization value has a linear relationship with at least one of the following:
the first ID;the second ID; andthe time slot index.
