Embodiment 1
[0375] Embodiment 1: Signal sending, receiving structure and internal multiplexing method
[0376] For the normal operation of the wireless system and terminal equipment, downlink and uplink access signals need to be provided respectively, and the access signal is a necessary signal for the wireless system. In the actual operation of communication systems and terminals, access signals need to be scanned and transmitted continuously. In addition to access signals, other signals such as reference signals used to measure, maintain and track synchronization and channel conditions also need to be scanned and transmitted, so access like this The time segment that carries the scanning signal and other scanning signals during the entry process can be called the scanning time interval STI. From the perspective of the base station, it is classified into the downlink transmission scanning time interval (DL TX Sweep Time Interval) and the uplink receiving scanning time interval (UL TX Swee...
Embodiment 2
[0409] Example 2: Content and sending method of message block
[0410] There are many contents in the MSG transmitted by the base station, and at least one of the following information can be selected:
[0411] 1. The time and frequency domain position information of the downlink STI, such as its absolute or relative position and period in the time and frequency domain, etc. There may be multiple sets of time and frequency domain position information for various downlink STIs. The relative position is generally based on the edge of the wireless frame, and the time difference and frequency difference are calculated. From the perspective of forward compatibility, the position of the STI is not necessarily fixed and sent periodically from a certain subframe or time interval, so the position of the STI needs to be notified in plain text, so that the terminal can obtain synchronization information similar to the level of the wireless frame. From the perspective of forward compatib...

[0427] Embodiment 3: In the case of insufficient MRS resources, the signal multiplexing structure in the STB
[0428] In the case of a device with a large number of RF channels, there are many beams that can be scanned at the same time. If the resources allocated to MRS cannot be expanded in the time dimension, there may be insufficient MRS resources in one STB.
[0429] The first solution: place the MRS that cannot be accommodated in other resources decoupled from the SS for transmission, and these decoupled resources can be notified in the MSG or specified in other signaling.
[0430] The second solution: expand in time, repeat the same SS, and send more MRSs on the extended time resources. Such as Figure 4 As shown, the SSs in STB2 and STB3 are exactly the same in terms of sequence, index, and coarse beams. The coarse beams are composed of fine beams of MRS3, 4, 5, and 6, while MRS3, 4, and 5 , 6 is divided into two STBs to send. This kind of time expansion basically be...
