Abstract
The embodiments herein related to a method in a network node, a network node, a method in a user equipment and a user equipment for handling base sequences in a communications network. The network node is configured to communicate with a first user equipment. The network node comprises information about a default base sequence and an alternative base sequence. The network node determines, for the first user equipment, that the alternative base sequence should replace the default base sequence. The network node sends information about the determined alternative base sequence to the first user equipment.
Claims18
A user equipment for handling base sequences in a communications network, the user equipment being configured to communicate with a network node, the user equipment comprising:
- one or more processors configured to cause the user equipment to:
- receive, from the network node, information that an alternative UE-specific base sequence should replace a cell-specific default base sequence;
- wherein the information indicating the determined alternative user equipment specific base sequence is separate to information relating to Sequence and Group Hopping, and
- replace the default cell-specific sequence with the alternative UE-specific base sequence, and
- transmit a reference signal derived from the alternative UE-specific base sequence.
A method in a user equipment for handling base sequences in a communication network, the user equipment being configured to communicate with a network node, the method comprising:
- receiving, from the network node, information that an alternative UE-specific base sequence should replace a cell-specific default base sequence;
- wherein the information indicating the determined alternative user equipment specific base sequence is separate to information relating to Sequence and Group Hopping, and
- replacing the default cell-specific sequence with the alternative UE-specific base sequence, and
- transmitting a reference signal derived from the alternative UE-specific base sequence.
