CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is based on PCT filing PCT/CN2018/122012, filed Dec. 19, 2018, which claims the priority to Chinese Patent Application No. 201711433214.8, filed Dec. 26, 2017 with the Chinese Patent Office, each of which is incorporated herein by reference in its entirety.

FIELD

The present disclosure generally relates to the technical field of wireless communications, and in particular to an apparatus and a method in a wireless communication system by which a numerology for sidelink communication in the New Radio (NR) technology is configured, and a computer readable storage medium.

BACKGROUND

In the conventional wireless communication technology, a numerology (including, for example, subcarrier spacing and a cyclic prefix type) used for sidelink communication is generally fixed, and a transmitting party and a receiving party perform the sidelink communication according to the fixed numerology. However, the fixed numerology is not applicable to the sidelink communication in the New Radio technology, which has higher requirements on a series of indicators such as delay and reliability.

SUMMARY

Brief summary of the present disclosure is given hereinafter, to provide basic understanding for certain aspects of the present disclosure. It should be understood that, the summary is not exhaustive summary of the present disclosure. The summary is not intended to determine key parts or important parts of the present disclosure, and is not intended to limit the scope of the present disclosure. An object of the summary is only to give some concepts of the present disclosure in a simplified form, as preamble of the detailed description later.

In view of the above, an object of at least one aspect of the present disclosure is to provide an apparatus and a method in a wireless communication system by which a numerology for sidelink communication can be configured, and a computer readable storage medium.

According to an aspect of the present disclosure, an apparatus in a wireless communication system is provided. The apparatus includes processing circuitry. The processing circuitry is configured to: determine, based on one or more of at least resource set configuration information, physical channel information and service type information, configuration information of one or more numerologies for sidelink communication; and control a base station to transmit the configuration information to user equipment for the user equipment to perform the sidelink communication based on the one or more numerologies, where a numerology comprises at least subcarrier spacing and a cyclic prefix type.

According to another aspect of the present disclosure, an apparatus in a wireless communication system is further provided. The apparatus includes processing circuitry. The processing circuitry is configured to: obtain one or more numerologies for sidelink communication; and control user equipment to perform the sidelink communication based on the one or more numerologies, where the one or more numerologies are determined based on configuration information from a base station or are pre-configured, and a numerology comprises at least subcarrier spacing and a cyclic prefix type.

According to another aspect of the present disclosure, a method in a wireless communication system is further provided. The method includes: determining, based on one or more of at least resource set configuration information, physical channel information and service type information, configuration information of one or more numerologies for sidelink communication; and controlling a base station to transmit the configuration information to user equipment for the user equipment to perform the sidelink communication based on the one or more numerologies, where a numerology comprises at least subcarrier spacing and a cyclic prefix type.

According to another aspect of the present disclosure, a method in a wireless communication system is further provided. The method includes: obtaining one or more numerologies for sidelink communication; and controlling user equipment to perform the sidelink communication based on the one or more numerologies, where the one or more numerologies are determined based on configuration information from a base station or are pre-configured, and a numerology comprises at least subcarrier spacing and a cyclic prefix type.

According to another aspect of the present disclosure, there is further provided a computer readable storage medium storing executable instructions which, when being executed by a computer, cause the computer to perform the method in a wireless communication system described above.

According to other aspects of the present disclosure, there are further provided computer program codes and computer program products for implementing the method provided in the present disclosure described above.

According to at least one aspect of the embodiments of the present disclosure, the used numerology is flexibly configured for the sidelink communication in the NR, thereby improving the communication performance of the sidelink communication, and meeting higher requirements for a series of indicators such as delay and system stability in the NR scenario.

Other aspects of the embodiments of the present disclosure are given in the following description, and the detailed description is intended to fully disclose preferred implementations of the embodiments of the present disclosure, but not to limit the present disclosure.
