Abstract

An information sending method and an information sending apparatus are disclosed. The method includes receiving configuration information configured to indicate that a same transport block is provided with Q transmission opportunities in R consecutive slots, and sending the transport block according to the configuration information. The problem of how to send a transport block using a transmission opportunity in the related art can be solved.

First claim

What is claimed is:

1. An information sending method, comprises:
receiving configuration information configured to indicate that a same transport block is provided with Q transmission opportunities in R consecutive slots, wherein Q is an integer greater than or equal to 1, R is an integer and 0<R≤Q; and
sending the transport block according to the configuration information, wherein the configuration information comprises at least one of:
the transport block is not sent at a transmission opportunity #t; and
in the same slot, in response to that a position of time domain resource of the transmission opportunity #t and positions of time domain resources of other transmission opportunities are not consecutive in terms of time domain, no DMRS or information is sent at the transmission opportunity #t;
wherein t is a transmission opportunity index and is an integer, and 0<t≤Q, wherein the transmission opportunity #t is part of the Q transmission opportunities,
wherein the transmission opportunity #t is determined in the one of following ways:
in response to that a time domain resource of one transmission opportunity of the Q transmission opportunities is less than a predefined value N, the one transmission opportunity is the transmission opportunity #t; wherein N is an integer greater than or equal to 1;
in response to that a time domain resource of the one transmission opportunity is less than M=f(L), the one transmission opportunity is the transmission opportunity #t, wherein L refers to any one of the following time domain resource lengths: a time domain resource length of one of nominal transmission opportunities, a time domain resource length of a first actual transmission opportunity, a total time domain resource length of all actual transmission opportunities, a shortest time domain resource length among those of the actual transmission opportunities, a time domain resource length of a nominal or actual transmission opportunity corresponding to any one of Redundancy Version RV={0,1,2,3}), and a longest time domain resource length among those of the actual transmission opportunities; and
in response to that a target bitrate of the one transmission opportunity is greater than a predefined target bitrate, the one transmission opportunity is the transmission opportunity #t.

2. The method of claim 1 , wherein the configuration information comprises:
in response to that frequency hopping across different transmission opportunities is enabled, no frequency hopping is carried out at the transmission opportunity #t.

3. The method of claim 2 , wherein
a frequency domain position of the transmission opportunity #t is the same as a frequency domain position of a second hop of a previous transmission opportunity or as a frequency domain position of a first hop of a following transmission opportunity, wherein the previous transmission opportunity or the following transmission opportunity and the transmission opportunity #t being consecutive in terms of time domain.

where L and X are integers greater than or equal to 1.

5. The method of claim 1 , wherein
the predefined target bitrate is notified by Radio Resource Control (RRC) or Downlink Control Information (DCI), or acquired from target bitrates in a Modulation and Coding Scheme (MCS) index.

6. The method of claim 1 , wherein the configuration information comprises:
an indication of time domain resource information of the Q transmission opportunities; and
an indication of a transmission scheme of the Q transmission opportunities.

7. The method of claim 6 , wherein
the time domain resource information comprises at least one of the following information combinations:
Information Combination I: a starting symbol Si of an i th transmission opportunity, a time domain duration Li of the i th transmission opportunity and a slot index of a slot where the i th transmission opportunity is located; or, the starting symbol Si of the i th transmission opportunity, the time domain duration Li of the i th transmission opportunity and a slot index of a second transmission opportunity;
Information Combination II: a start and length indicator SLIVi of the i th transmission opportunity and the slot index of the slot where the i th transmission opportunity is located;
or, the start and length indicator SLIVi of the i th transmission opportunity and the slot index of the second transmission opportunity;
Information Combination III: the starting symbol Si of the i th transmission opportunity, the time domain duration Li of the i th transmission opportunity and a cross-slot indicator which is related to the number of the Q transmission opportunities or the number of times of repeated transmission of the transport block;
Information Combination IV: the start and length indicator SLIVi of the i th transmission opportunity and the cross-slot indicator;
Information Combination V: the starting symbol Si of the i th transmission opportunity and the time domain duration Li of the i th transmission opportunity; and
Information Combination VI: the start and length indicator SLIVi of the i th transmission opportunity;
wherein i is an integer and 0<t≤Q.

8. The method of claim 7 , wherein
the SLIVi is configured for obtaining the time-domain starting symbol Si and the time domain duration Li of the i th transmission opportunity.

9. The method of claim 7 , wherein
the time domain resource information is configured by an upper layer.

10. The method of claim 9 , wherein
the time domain resource information is jointly indicated through configuration by the upper layer and RRC signaling; or
the time domain resource information is jointly indicated through configuration by the upper layer and DCI signaling.

11. The method of claim 7 , wherein
the slot index of a first transmission opportunity of the ith transmission opportunity is determined by a slot offset, which refers to a duration from a downlink transmission of DCI to an uplink transmission of Physical Uplink Shared Channel (PUSCH).

12. The method of claim 7 , wherein
the cross-slot indicator is a bitmap indicator, and indicates whether a current transmission opportunity crosses over a slot boundary through bit flipping, and the first bit in the cross-slot indicator represents slot index information of the second transmission opportuni
