Abstract

The embodiments of the invention provide a reference signal sequence transmission method and a piece of equipment. The method comprises the following steps: user equipment receives configuration information sent by a base station, wherein the configuration information is used to indicate a first basic sequence group allocated by the base station for the user equipment, the configuration information is generated by the base station based on a division mode of basic sequence groups in a communication system where the base station is located, the division mode divides the basic sequence groups in the communication system into multiple basic sequence sets, each basic sequence set contains at least one basic sequence group, at least one of the multiple basic sequence sets contains at least two basic sequence groups, and a first basic sequence set to which the first basic sequence group belongs is one of the multiple basic sequence sets; the user equipment determines a first basic sequence set according to the configuration information; and the user equipment generates a reference signal according to the first basic sequence set, and sends the reference signal to the base station.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for transmitting a reference signal sequence. Background technique [0002] With the popularization of smart terminals, users need higher uplink transmission rates, and base stations need higher spectrum utilization. Uplink multi-user multiple-input multiple-output (Multi-User Multiple-Input Multiple-Output, MU-MIMO) can support multiple user equipment (User Equipment, UE) to use the same time-frequency resources to send data to the base station, or one UE can also By supporting more layers on the same time-frequency resource, the uplink transmission rate can be increased and the spectrum efficiency can be improved. [0003] In the current LTE system, each cell supports uplink MIMO with a maximum of 4 streams, and the uplink capacity is small. Contents of the invention [0004] Embodiments of the present invention provide a refe...
