Background

A significant feature of the fifth generation (5th generation, 5G) mobile communication system compared with the fourth generation (4th generation, 4G) mobile communication system is the increased support for ultra-reliable and low-latency communications (URLLC) services.

For URLLC traffic, a typical requirement is that 32 bytes of data are sent within 1 millisecond (ms) with a reliability of 99.999%. It should be noted that the above performance index is only an example, different URLLC services may have different requirements on reliability, for example, in some extremely harsh industrial control application scenarios, the transmission success probability of URLLC service data needs to reach 99.9999999% within 0.25 ms.

Three multiplexes of SS/PBCH block and quasi co-located (QCLed) system information block 1(system information block 1, SIB 1)/Remaining Minimum System Information (RMSI) supported by the NR system, see fig. 2, namely pattern1, pattern2 and pattern3, respectively, and for pattern1, the SS/PBCH block and CORESET #0 (or Type0-PDCCH)/PDSCH exist in a time division multiplexing form, and are mainly applied to FR 1; in pattern2, the SS/PBCH block and the PDSCH of QCled exist in a frequency division multiplexing mode; in pattern3, the SS/PBCH block and QCled CORESET #0 (or Type0-PDCCH)/PDSCH exist in a frequency division multiplexing mode. The pattern2 and the pattern3 are mainly used for FR2 and higher frequency bands (including a shared frequency band operating at 60 GHz). in the embodiment of the present application, the configuration of frequency domain resources under the pattern2 and/or the pattern3 is mainly discussed.

With reference to the network framework diagram of fig. 1, a resource allocation method according to an embodiment of the present application includes steps 301 to 303:

301. the method comprises the steps that the network equipment determines frequency domain resources used for sending broadcast signals, the occupied proportion of the frequency domain resources in a system bandwidth is larger than or equal to a preset proportion, and the system bandwidth represents the bandwidth used when the network equipment and the terminal equipment communicate;

in a shared access system of a high frequency band (e.g., 60GHz), a requirement of occupying an Optical Channel Bandwidth (OCB) is required to be satisfied when a network device and a terminal device communicate with each other, that is, in the communication between the network device and the terminal device, a channel to which the network device belongs is occupied by a bandwidth of not less than a preset proportion, where the preset proportion is generally 70%.

In the embodiment of the present application, a Resource Block (RB) occupied by a frequency domain resource for transmitting a broadcast signal is referred to as an occupied resource block. The Resource Block may also be defined as a Physical Resource Block (PRB).

The broadcast signal includes system information and a synchronization information block (SS/PBCH block), the system information being indicated by a control resource set of the zeroth class (core #0 or core #0), the core #0 being transmitted through the Type0 PDCCH.

The resource blocks occupied by the core set #0 may be continuous or discontinuous, in this embodiment, the resource block occupied by the core set #0 is referred to as the core set #0 resource block, when the resource block occupied by the core set #0 is discontinuous, the core set #0 is divided into a plurality of core set #0 sub-blocks, and the content included in the plurality of core set #0 sub-blocks may be the same or different, in this embodiment, the core set #0 sub-block may also be a core set #0 subset, in this embodiment, only the core set #0 sub-block is taken as an example for explanation, refer to fig. 4, the core set #0 includes a plurality of core set #0 sub-blocks 401 to 401, and the interval between adjacent core set #0 sub-blocks is the core set #0 interval 404 to 405.

The offset (offset) between the starting position of the Type 0PDCCH and the starting position of the SS/PBCH block is a first offset, and the occupied resource block is an offset resource block.

Taking multiplexing conditions based on pattern3 as an example, referring to fig. 5.1, when the value of CORESET #0 and the value of the first offset are positive, the frequency domain position of Type 0PDCCH is higher than the SS/PBCH block, otherwise, referring to fig. 5.2, when the value of CORESET #0 and the value of the first offset are negative, the frequency domain position of Type 0PDCCH is lower than the number of CORESET #0 resource blocks in the present embodiment of SS/PBCH block, which is the absolute value of the value of CORESET #0, and the number of offset resource blocks is the absolute value of the first offset. Under the multiplexing condition of pattern2, the value of CORESET #0 and the value of the first offset are similar to the frequency domain location relationship of Type 0PDCCH and SS/PBCH block and the multiplexing condition of pattern3, and are not repeated herein with reference to fig. 5.3 and fig. 5.4.
