Embodiment 1

[0165] Assuming that the subcarrier spacing of the unlicensed communication system is 30KHz, an example of the transmission configuration information of the above-mentioned first information is shown in Table 2:

[0166] Table 2

[0167]

[0168] The First symbol index in the above Table 2 is the position (information 1) of the first search space of the physical control channel associated with the SSB in the same time slot in the above embodiment.

[0169] The Number of search space sets per slot is the number n of search spaces of the physical control channel in one time slot in the above embodiment (information 2).

[0170] The DRS window (DRS window) is the candidate transmission time window in the above embodiment. The DRS window period is the week T of the candidate transmission time window in the above embodiment (information 3). The DRS window duration is the length L of the candidate transmission time window in the above embodiment (information 4).

[0171] The Q...

Embodiment 2

[0181] Still take the configuration information in Table 2 as an example.

[0182] Please refer to Figure 7 , when the network-side device determines to send the first information with the transmission configuration information whose index is 1, the network-side device performs channel idle monitoring within the DRS window (3ms) at a monitoring granularity of 0.5 slots, and there are 12 times (0.5 slots in total) 0.25ms, 3ms, a total of 12 time slots) to try to send LBT opportunities.

[0183] Figure 7 In the illustrated embodiment, the network side device detects that the channel is idle in the first slot (that is, slot#0) of a DRS window, and the network side device detects that the channel is idle in the first to third slots (that is, slot#0, slot#1, slot2#) The first information (the SSB, the Type 0 PDCCH associated with the SSB, and the system information of the Type 0 PDCCH scheduling) is sent on the SSB. The network side device detects that the channel is idle in t...

Embodiment 3

[0188] Please refer to Figure 8 , this embodiment and Figure 6 The difference of the illustrated embodiment is that the network side device is configured with: information 6, that is, the number and / or position of SSBs sent in one time slot. Figure 8 In the described embodiment, one SSB is sent in one time slot.

[0189] Embodiment 4 of the present invention

[0190] Please refer to Figure 9 , assuming that the network side device sends the first information according to the configuration information whose index is 0, the terminal 1 (UE1) performs SSB monitoring on the running carrier, and detects SSB#2 and SSB#3, according to the transmission configuration carried by SSB2 and SSB#3 Information, get the transmission configuration information whose index is 0. And according to the monitoring time of SSB#2, the start time of the DRS window can be obtained, combined with the period and length of the DRS window, the absolute time window of the DRS can be obtained, namely F...

Abstract

The embodiment of the invention provides an information receiving method, an information sending method, a terminal and network side equipment. The information receiving method comprises the followingsteps: detecting an SSB; determining a candidate SSB set quasi-co-located with the detected first SSB according to the transmission configuration information of the first information, the first information comprising the SSB; performing first processing according to the first SSB and the candidate SSB set, the first processing comprising one of the following: receiving system information of physical control channel scheduling associated with the first SSB; carrying out wireless link monitoring; and performing the management and measurement of radio resources. The embodiment of the invention is used for solving the problems of how to send information by a network side and how to receive information by a terminal in an unauthorized communication system.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular, to an information receiving method, a sending method, a terminal, and a network side device. Background technique [0002] In the 5G communication system, the configuration information of the physical control channel (Type 0 PDCCH) for scheduling system information is sent in the synchronization signal / physical broadcast channel signal block (SS / PBCH block, or SSB). For frequency bands below 6 GHz, the resources of SSB / PBCH and Type0 PDCCH adopt multiplexing mode 1, that is, SSB / PBCH and Type0 PDCCH cannot overlap in the time domain. In this mode, the terminal can 0 A time slot (slot) monitors the Type0 PDCCH, where n 0 The following conditions: [0003] For SSB with index i, if Type0 PDCCH is located in an even frame number, if Type0 PDCCH is located in odd frame numbers. Among them, μ is the subcarrier spacing. [0004] The ...
