Those skilled in the art can know that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0180] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1, or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than FIG. 1.

In addition, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0182] In the related art, in order to reduce the energy consumption of the base station and the network side, research on Network Energy Saving (NES) technology is carried out.

[0183] In some embodiments, the time domain location of PRACH transmission occasion can be semi-statically configured, and the base station can periodically wake up to detect the reception of PRACH, but this can limit the use of (deeper) sleep mode by the base station to save energy. Therefore, the reception of PRACH can be limited by using time domain techniques to increase the sleep time of the base station to achieve the purpose of energy saving.

[0184] In some embodiments, the PRACH resource configuration information can be configured by semi-static signaling, for example, the configuration information of PRACH resource can be provided by system information block 1 (SIB1) or UE-dedicated RRC signaling.

[0185] In some embodiments, the time-frequency resource for PRACH transmission can be determined according to the configuration information provided by SIB1 or UE-dedicated RRC signaling. The terminal and the base station can determine the valid random access occasion (RO) that can be truly used for PRACH transmission according to the configuration information, in combination with time division duplex (TDD) structure, synchronization signal block (SSB) time domain location and downlink transmission and other related information. Further, the terminal and the base station can determine the mapping relationship between SSB and RO according to the foregoing configuration, SSB configuration and valid RO, so that the terminal can send the preamble bound with the SSB related to itself on the determined valid RO according to its own needs.

[0186] It should be noted that the foregoing configuration and resource determination of PRACH are directed to all terminals within the cell. If the transmission behavior of the common channel or signal changes (including but not limited to changes in time domain resource, frequency domain resource, spatial domain resource, etc.), non-NES UE (i.e. non-NES UE) cannot recognize the changes and will still perform reception and transmission of the common channel or signal according to the configured PRACH resource, but part of the resource understood by non-NES UE can no longer be used to transmit the common channel or signal, thereby causing the deterioration of the transmission performance of non-NES UE.

[0187] Therefore, in some embodiments, for a terminal supporting NES technology (i.e., NES UE), the network side can configure a default physical random access channel (PRACH) resource and an additional PRACH resource for the terminal, and for a non-NES UE, the network side can configure a default PRACH resource for the terminal; on this basis, the network side can adjust the additional PRACH resource without adjusting the default PRACH resource, so as to avoid affecting the non-NES UE.

[0188] However, there is no clear method for determining the initial resource location of the additional PRACH resource.

[0189] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a communication method, and the method comprises:

[0190] In step S2101, the terminal determines an initial resource location of a first PRACH resource based on a predefined rule.

[0212] In step S2102, the network device determines the initial resource position of the first PRACH resource based on a predefined rule.

[0213] In some embodiments, the first PRACH resource is a resource where the adjustable PRACH is located, and the disclosure embodiments do not limit the adjustment manner of the first PRACH resource.

[0218] The RACH configuration index indicated by the second configuration information is used to determine the RACH related information of the second PRACH resource, including but not limited to time domain resource, format, period, etc.
