example 1

[0103] Indicate the bandwidth of a BWP in the MIB, and carry 1 bit (bit) to indicate the relative position of SSB and CORESET, where "1" indicates that SSB is below the frequency domain of CORESET; "0" indicates that SSB is above the frequency domain of CORESET.

[0104] The UE obtains the frequency domain resource information of the CORESET of the RMSI and the information of the Initial DL BWP according to the information in the MIB.

[0105] The UE determines the size of the DCI according to the BWP bandwidth, and the maximum schedulable bandwidth is the BWP bandwidth.

[0106] The UE determines the RB indexing (indexing) according to the relative position of the SSB and the CORESET, the bandwidth of the BWP, and the position of the CORESET.

[0107] If the relative position indication of SSB and CORESET is "1", then (the maximum RB-BWP bandwidth of CORESET) is determined as the reference point of RB numbering.

[0108] If the relative position indication of SSB and CORESET...

example 2

[0116] The UE obtains the frequency domain resource information of the CORESET of the RMSI and the information of the Initial DL BWP according to the information in the MIB.

[0117] The bandwidth of a BWP is indicated in the RMSI. The relative position indication of COREST and SSB carrying 1 bit in RMSI: "1" indicates that SSB is below the frequency domain of CORESET; "0" indicates that SSB is above the frequency domain of CORESET.

[0118]On the Initial DL BWP, the UE determines the size of the DCI according to the bandwidth of the Initial DL BWP, and determines the RB indexing with the bandwidth of the Initial DL BWP.

[0119] On the active BWP (that is, non-Initial BWP), the UE determines the size of the DCI according to the bandwidth of the BWP. RB indexing is determined according to the relative position of SSB and CORESET, the bandwidth of BWP, and the position of CORESET.

example 3

[0121] The bandwidth of the BWP predefined by the network is N resource blocks (RBs).

[0122] The UE obtains the frequency domain resource information of the CORESET of the RMSI and the information of the Initial DL BWP according to the information in the MIB.

[0123] Among them, 1 bit in the MIB indicates the relative position of SSB and CORESET: "1" indicates that SSB is below the frequency domain of CORESET; "0" indicates that SSB is above the frequency domain of CORESET.

[0124] For example: the bandwidth of the BWP predefined by the network.

[0125] The UE determines the size of the DCI according to the bandwidth of the BWP predefined by the network

[0126] RBnumbering is determined according to the bandwidth of the BWP predefined in the network, the position of the CORESET, and the relative position of the CORESET and the SSB.

Abstract

The embodiment of the invention provides a processing method and device. The method comprises: determining the size of DCI of a UE according to first information, the first information comprising anyone or a combination of more of the following: the bandwidth of a BWP, the bandwidth of a CORESET, the sum of the bandwidth of the CORESET and the bandwidth of an SSB, and the bandwidth of an InitialDL BWP; and / or according to the second information, determining RB numbering, wherein the second information comprises any one or more of the following combinations: the bandwidth of the BWP, the relative position of the SSB and the CORESET, the position of the CORESET, the bandwidth of the CORESET, the sum of the bandwidth of the CORESET and the bandwidth of the SSB, and the bandwidth of the Initial DL BWP. In the embodiments of the present invention, different UEs can transmit broadcast messages on the same time-frequency resource, thereby saving transmission resources and improving transmission efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a processing method and device. Background technique [0002] Different user equipment (User Equipment, UE) understand different sizes of the initial downlink bandwidth part (Initial DLBWP). If different UEs switch to the same bandwidth part (Bandwidth Part, BWP), if the common search space (Common search space) is configured , CSS), the UE receives broadcast information according to the DCI size (size) defined by the Initial DL BWP, and the DCI sizes used by different UEs may be different, and cannot be mapped to the same frequency domain resources. Contents of the invention [0003] An object of the embodiments of the present invention is to provide a processing method and device to solve the problem that UEs cannot be mapped to the same frequency domain resources when their Initial DLBWPs are different. [0004] In the first aspect, a p...
