Embodiment 1

[0062] In this embodiment, the SSB has multiple subcarrier intervals (D values), such as 120 kHz, 240 kHz and 480 kHz. There are many possibilities for the subcarrier spacing (C value) of the associated PDSCH carrying RMSI, CORESET indicating RMSI PDSCH, PDSCH at initial access and PDSCH broadcasting system information, such as 60kHz, 120kHz, 240kHz and 480kHz. At this time, the first information length A=1, which means that the two states are C=D and C=0.5D.

[0063] Table 1 gives an example, where the first information status is 0 representing C=D, and 1 representing C=0.5D. The values ​​of C are 120kHz, 240kHz and 480kHz, and the values ​​of D are 60kHz, 120kHz, 240kHz and 480kHz. The indication of 1 bit of the first information can realize the subcarrier spacing combination of 6 kinds of SSB subcarrier spacing and SS / PBCH bloc associated PDSCH bearing RMSI, CORESET indicating RMSI PDSCH, PDSCH at initial access and PDSCH of broadcasting system information Compared with t...

Embodiment 2

[0082] In this embodiment, the SSB has multiple subcarrier intervals (D values), such as 120 kHz, 240 kHz and 480 kHz. There are many possibilities for the subcarrier spacing (C value) of the associated PDSCH carrying RMSI, CORESET indicating RMSI PDSCH, PDSCH at initial access and PDSCH broadcasting system information, such as 60kHz, 120kHz, 240kHz and 480kHz. At this time, the first information length A=1, and the subcarrier spacing of each SSB and the state corresponding to the relevant RMSI CORESET and RMSI PDSCH are independently specified.

[0083] Table 3 gives an example. For the subcarrier spacing of SSB 120kHz, the first information state 0 represents C=D, and the state 1 represents C=0.5D; for the subcarrier spacing of SSB 240kHz, the first information state 0 represents C=D. 0.5D, state 1 represents C=0.25D; for the subcarrier spacing of SSB 480kHz, the first information state 0 represents C=D, and state 1 represents C=0.25D.

Embodiment 3

[0089] In this embodiment, the SSB has multiple subcarrier intervals (D values), such as 120 kHz, 240 kHz and 480 kHz. There are two possibilities for the subcarrier spacing (C value) of the associated PDSCH carrying RMSI, CORESET indicating RMSI PDSCH, PDSCH at initial access, and PDSCH broadcasting system information, such as 120kHz and 240kHz, or 240kHz and 480kHz. At this time, the first information length A=1, and the two states directly correspond to the subcarrier spacing to be indicated.

[0090] When the two subcarrier intervals indicated by the first information are not 60kHz and 120kHz, the standard needs to consider additional support methods, such as the introduction of FR3 in Embodiment 1, which describes the two subcarrier intervals associated with FR3. The concept of FR3 is not introduced, and two sub-carrier spacings are directly specified separately for carriers that are not in the current FR1 and FR2.

[0091] When the two subcarrier intervals indicated by ...

Abstract

The present application discloses a high-frequency discovery signal transmission method, which is used in an unlicensed frequency band of a 5G system. The method includes: the SSB includes first information, and the subcarrier spacing of the SSB is the first subcarrier spacing; In order to indicate the subcarrier spacing of the PDCCH and PDSCH associated with the SSB, that is, the second subcarrier spacing; the first information is A bits, used to indicate that B≥2 A the second subcarrier spacing. The present application also includes terminal equipment, network equipment and systems using the method. This application solves the problem of how to realize the transmission of discovery signals in high frequency bands, which can be used in high frequency bands above 6 GHz, especially in unlicensed frequency bands above 6 GHz, which can provide better access for NR-based unlicensed frequency band access devices. into performance.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method, device and system for transmitting high-frequency discovery signals. Background technique [0002] The 5G new air interface (NR) has completed two versions, R15 and R16. According to the current version, it supports up to 52.6GHz. According to the original vision of 5G, the design of 5G NR needs to support the use of 100GHz frequency. In higher frequency bands, it is necessary to consider supporting larger bandwidth while overcoming the adverse effects of large path loss, so it is necessary to enhance the existing NR design. [0003] At present, NR has supported the downlink data shared channel (PDSCH) and downlink control channel (PDCCH) of several subcarrier spacings such as 15kHz, 30kHz, 60kHz, and 120kHz. The frequency band above 52.6GHz has a wider bandwidth than before and there are a large number of unlicensed frequency bands. It is n...
