According to the technical scheme, enough bits in the random access response uplink grant can be ensured to be used as the frequency domain resource allocation of the Msg3 PUSCH, and further the flexibility and/or the frequency hopping performance of the frequency domain resource allocation of the terminal equipment with the enhanced light capacity are ensured.

Description

Processing method, communication device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a processing method, a communications device, and a storage medium.

Background

According to the existing protocol, when the frequency-domain hopping of the PUSCH (Physical UplinkSharedCHannel ) of the Msg3 (message 3) is enabled, the 1-2 bits of the most significant bit of the PUSCH frequency resource allocation (frequency-domain resource allocation) field in the UL grant (RAR (Random AccessResponse, random access response) will be used as the hopping bits of the PUSCH of the Msg 3; i.e. only the remaining L bits (l=14-number of hopping bits) in the PUSCH frequency resource allocation field are used as PUSCH frequency domain resource allocation bits.

In the course of conception and implementation of the present application, the inventors found that: if the most significant 2 bits of the PUSCH frequency resource allocation field in the RAR UL grant are used as the hopping bits for the Msg3 PUSCH, only the remaining 14-2=12 bits in the PUSCH frequency resource allocation field are available for frequency domain resource allocation for R18 eRedcap UEs (R18 enhanced lightweight capability terminal devices). In other words, taking the example of a subcarrier spacing of 15KHz, about 20 RBs (Resource Block) out of 106 RBs corresponding to the 20MHz bandwidth portion cannot be used for PUSCH frequency domain Resource allocation of R18 eredcapuce. Therefore, the above-described manner of determining the frequency domain resource allocation bits may cause a problem that the available resources for Msg3 PUSCH frequency domain hopping of the R18 eRedcap UE are limited. Especially when the R18 eRedCap, rel-17 RedCap UE or the legacy UE coexist in the same cell, the problem of limited available resources for frequency hopping of the R18 eRedCap UE frequency domain is further aggravated.

The foregoing description is provided for general background information and does not necessarily constitute prior art.
