Embodiment 1

[0056] This embodiment provides a control channel detection method, see figure 1 shown, which includes:

[0057] S101: Determine whether the control channel information included in H control channel elements of the first type is the same according to signaling information and / or preset rules; wherein, H is a positive integer greater than or equal to 2.

[0058] It should be understood that in this embodiment, according to specific application requirements, it is possible to flexibly determine whether the control channel information included in the H first-type control channel elements is the same according to the signaling information, or determine the H first-type control channel elements according to preset rules. Whether the control channel information included in the control channel elements is the same; or determine whether the control channel information included in the H first-type control channel elements is the same in combination with signaling information and preset...

Embodiment 2

[0370] In an example in this application embodiment, the H control channel elements include the same control channel information, including the same first type of control channel information, and the same first type of control channel information satisfies at least one of the following characteristics: H candidates The control information bits before channel coding included in the control channel are the same; the cyclically shifted scrambling sequences during channel coding of the H candidate control channels are the same; the control information bits after channel coding included in the H candidate control channels are different; H The aggregation degrees of the candidate control channels are different; the channel-coded scrambling sequences of the H candidate control channels are different.

[0371] For example, if Figure 16 As shown, the control information based on K bits is the DCI bit, and P CRC bits (cyclic shift check bits) are obtained based on the K-bit control inf...

Embodiment 3

[0375] In this embodiment, the base station (such as TRP) and the terminal agree that the H SSS / SS / CORESET / SSS ocassion / SSocassion are repeated transmissions, that is, the control channel information transmitted in the H SSS / SS / CORESETs is the same.

[0376] Optionally, at this time, the same control channel modulation symbol is transmitted in the subcarriers corresponding to the H SSS / SS / CORESET / SSS ocassion / SS ocassion.

[0377] One method can be that the number of subcarriers / CCEs included in H SSS / SS / CORESET / SSS ocassion / SS ocassion is the same, and the CCE indexes are in one-to-one correspondence, and the corresponding subcarriers in the corresponding CCEs include the same modulation symbol. Such as Figure 18 shown.

[0378] Another method can be that the number of subcarriers / CCEs included in H SSS / SS / CORESET / SSS ocassion / SS ocassion is in multiples, and one subcarrier in one SSS / SS / CORESET / SSS ocassion / SS ocassion The / CCE corresponds to multiple subcarriers / CCEs of...

Abstract

The embodiment of the invention provides a control channel detection method and device, an information element transmission method and device, equipment and a medium. Whether control channel information included in H (H is greater than or equal to 2) first-class control channel elements is the same or not can be determined according to signaling information and / or a preset rule; therefore, the control channel can be monitored according to the determined result, so that the communication node equipment can repeatedly send the same control channel information through a plurality of candidate control channels, the robustness of the PDCCH can be improved, and the transmission coverage distance of the PDCCH is increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control channel detection and information element transmission method, device, equipment and medium. Background technique [0002] The transmission configuration of PDCCH (Physical Downlink Control Channel, physical downlink control channel) in NR (New Radio, new generation wireless communication) is more flexible than LTE (Long Term Evolution, long-term evolution). The following concepts are introduced in NR: CORESET (Control Resource Set, control channel resource set), control channel search space set, the configuration information in one control channel search space set will further configure the candidate The number of control channels, each search space corresponds to an aggregation degree, and the number of candidate control channels included in an aggregation degree can be a value in {0, 1, 2, 3, 4, 5, 6, 8}. A search space set is associated with a CORESE...
