In order to improve resource utilization, the network device may send first information (configured by high-layer signaling) to the terminal device to indicate that the terminal device can multiplex the uplink time-frequency resources of other terminal devices. For example, the terminal device 1 may be a long-duration terminal device, that is, a terminal device with a long data transmission duration, such as an eMMB user terminal. The terminal device 2 may be a short-duration terminal device, such as a URLLC user terminal. In order to meet the low latency requirement of the terminal device 2 , the network device may schedule the terminal device 2 to reuse the uplink time-frequency resources of the terminal device 1 . When the network device determines that the terminal device 2 multiplexes the uplink time-frequency resources of the terminal device 1 , the network device may deliver the first information to the terminal device 1 .

Optionally, the first information may be DCI. When sending DCI to the terminal device, the network device may send the DCI to the terminal device according to a preset sending cycle, and the sending cycle of the network device may be equal to the listening cycle of the terminal device. The DCI used by the network equipment can be the DCI corresponding to 5G NR DCI Format2_4. The format of the above-mentioned DCI can also be other predefined formats, and the predefined format mentioned here is different from the DCI format indicating PDCCH or indicating GC-PDCCH transmission, and specifically can be the newly defined DCI format in the subsequent evolution communication system, or are other DCI formats in existing communication systems and so on. In the manner in which the above-mentioned DCI format is another predefined format, the flexible realization of DCI is facilitated.

The N can be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16 and so on. In some examples, the value of N may be an integer multiple of 2 or an integer multiple of 7. Of course, the embodiment of the present application does not limit that N may take other values. When the uplink multiplexing time-frequency resource indication field occupies 1 bit, a value of 1 in the uplink multiplexing time-frequency resource indication field may be used to indicate that the corresponding time-frequency resource is an uplink multiplexing time-frequency resource. In some examples, a value of 0 in the indication field of the uplink multiplexing time-frequency resource may be used to indicate that the corresponding time-frequency resource is an uplink multiplexing time-frequency resource, which is not limited in this embodiment of the present application. When the uplink multiplexing time-frequency resource indication field occupies multiple bits, the value of the uplink multiplexing time-frequency resource indication field can be used to indicate that the corresponding time-frequency resource is the uplink multiplexing time-frequency resource according to the actual situation.

For example, assuming that the first time-frequency resource includes 3 OFDM symbols, the high-level signaling of the network device configures the 2 OFDM symbols into 2 groups, and the first information includes 8 uplink multiplexing time-frequency resource indication fields, then the terminal device After receiving the first information, the uplink multiplexing time-frequency resource indication fields are divided into two groups, the first group of uplink multiplexing time-frequency resource indication fields are used to indicate the first group of OFDM symbols, and the second group of uplink multiplexing time-frequency resource indication fields are used to indicate The fields are used to indicate the OFDM symbols of the second and third groups.

Wherein, when there are Y subbands in the frequency domain resource, the subband at the corresponding position may be indicated by a bit-map (bit-map) in the indication domain of the uplink multiplexing time-frequency resource. When the number of subbands in the frequency domain resource is 1, a bitmap may not be needed to indicate the corresponding subband; when the number of subbands in the frequency domain resource is Y>=2, Y uplink time-frequency resources can be multiplexed The indication fields are used to indicate subbands, and the Y uplink multiplexing time-frequency resource indication fields are in one-to-one correspondence with the Y subbands. The terminal device can determine whether the corresponding subband includes uplink multiplexing frequency domain resources by identifying the values of the first Y uplink multiplexing time-frequency resource indication fields in the ith group.
