Abstract

Disclosed are a data multiplexing transmission method, a base station, a terminal, and a storage medium. The method comprises: a base station sends service resource occupation information corresponding to a first terminal by means of a control channel, so that a second terminal performs data transmission processing on the basis of the service resource occupation information when detecting the service resource occupation information sent on the control channel. The method, base station, terminal, and storage medium provided by the present application provide a resource multiplexing solution, solve the problem of service resource overlaps between different users, and improve the utilization efficiency of uplink transmission resources.

First claim

What is claimed is:

1. A data transmission method, comprising:
a base station receiving a URLLC service request sent by a first terminal and allocating resources occupied by transmission of the URLLC service for the first terminal;
wherein: the first terminal and a second terminal support transmission and reception of data in eMBB and URLLC modes; before receiving the URLLC service request, the base station separately allocates time-frequency resources for transmitting enhanced mobile broadband (eMBB) uplink data for the first terminal and a second terminal and separately sends allocated time-frequency resource information to the first terminal and the second terminal; the eMBB service comprises video service; and the URLLC service comprises automatic driving service;
the base station generating a control command and broadcasting the control command through the control channel;
wherein: the control command carries URLLC service resource occupation information corresponding to the resources occupied by the transmission of the URLLC service; the URLLC service resource occupation information has therein carried a bitmap information; the number of bits contained in the bitmap information is equal to the number of all the resources required to be occupied for transmitting the URLLC service, wherein each resource corresponds to one bit; and the resources comprises: a PRB, a PRB group, a subcarrier, a sequence, a codeword, a symbol and a time slot; and
the second terminal performing eMBB uplink data transmission processing based on the URLLC service resource occupation information, when detecting the URLLC service resource occupation information sent on the control channel.

2. The method according to claim 1 , further comprising:
the base station obtaining all the resources required to be occupied for transmitting the URLLC service, generating one bit for each resource correspondingly, and generating the bitmap information based on the bits.

3. The method according to claims 1 , wherein
the control channel comprises: a group common physical downlink control channel (Group common PDCCH); and
the control command comprises: a Group common PDCCH control command.

4. A base station comprising:
a memory; and a processor coupled to the memory, which is configured to perform, based on instructions stored in the memory, the method according to claims 1 .

5. A non-transitory computer-readable storage medium having thereon stored computer instructions which, when executed by a processor, implement the method according to claims 1 .

6. A data transmission method, comprising:
a second terminal detecting a control command broadcast by a base station through a control channel;
wherein: a first terminal and the second terminal support transmission and reception of data in eMBB and URLLC modes; before receiving a URLLC service request sent by the first terminal, the base station separately allocates time-frequency resources for transmitting enhanced mobile broadband (eMBB) uplink data for the first terminal and a second terminal and separately sends allocated time-frequency resource information to the first terminal and the second terminal; the eMBB service comprises video service; the URLLC service comprises automatic driving service; the control command carries URLLC service resource occupation information corresponding to resources occupied by the transmission of the URLLC service allocated to a first terminal; the URLLC service resource occupation information has therein carried a bitmap information; the number of bits contained in the bitmap information is equal to the number of all the resources required to be occupied for transmitting the URLLC service, wherein each resource corresponds to one bit; and the resources comprises: a PRB, a PRB group, a subcarrier, a sequence, a codeword, a symbol and a time slot; and
the second terminal performing eMBB uplink data transmission processing based on the URLLC service resource occupation information when detecting the URLLC service resource occupation information sent on the control channel;
wherein the second terminal performing the eMBB uplink data transmission processing based on the URLLC service resource occupation information comprises:
the second terminal judging whether time-frequency resources for transmitting the eMBB uplink data overlap with time-frequency resources corresponding to the URLLC service resource occupation information based on the URLLC service resource occupation information; and
the second terminal cancelling transmitting the eMBB uplink data under the condition that time-frequency resources for transmitting the eMBB uplink data overlap with time-frequency resources corresponding to the URLLC service resource occupation information.

7. The method according to claim 6 , the second terminal performing data transmission processing based on the service resource occupation information comprises:
the second terminal continuing transmitting the eMBB uplink data under the condition that time-frequency resources for transmitting the eMBB uplink data do not overlap with time-frequency resources corresponding to the URLLC service resource occupation information.

8. The method according to claims 6 , wherein the control channel comprises:
a group common physical downlink control channel (Group common PDCCH); and
the control command comprises: a Group common PDCCH control command.

9. A terminal comprising:
a memory; and a processor coupled to the memory, which is configured to perform, based on instructions stored in the memory, the method according to claims 6 .

10. A non-transitory computer-readable storage medium having thereon stored computer instructions which, when executed by a processor, implement the method according to claim 6 .
