Abstract: A user equipment (UE) may determine, based on a criterion, whether to indicate, to a gNB, that it is a reduced capability (RedCap) UE during or after a random access (RA) procedure, and indicate that it is the RedCap UE during or after the RA procedure according to a determination result. The RedCap UE has a reduced quantity of receive branches or a reduce bandwidth than a non-RedCap UE. The gNB may determine whether a first message received during the RA procedure indicates that the UE is the RedCap UE. When the first message indicates the UE as the RedCap UE, the gNB sends a second message to the UE during the RA procedure using a coverage recovery technique. When the first message does not indicate the UE as the RedCap UE, the gNB determines whether the UE is the RedCap UE after the RA procedure is completed.

Abstract: A method implemented by an access node includes sending, by the access node to a user equipment (UE), an indicator indicating use of coverage enhancement technique, the indicator being sent prior to the UE achieving a radio resource control (RRC) connected state with the access node; receiving, by the access node from the UE, an uplink transmission in accordance with the indicator; and sending, by the access node to the UE, a contention resolution message in accordance with the indicator.

Abstract: In a control information transmission method according to present disclosure, a user equipment acquires configuration information of an enhanced physical downlink control channel (EPDCCH) set. The user equipment determines, according to the configuration information and from the EPDCCH set, at least one EPDCCH set in which an EPDCCH needs to be monitored. The user equipment monitors an EPDCCH on a resource corresponding to the at least one EPDCCH set, to acquire control information sent by a base station.

Abstract: Embodiments of the present invention propose a D2D communications method, apparatus, and system. In the solution, a D2D SPS available period in which a first terminal is capable of using a D2D SPS resource is greater than one SC period. Therefore, in the D2D SPS available period, the first terminal needs to determine the D2D SPS resource only one time, and a second terminal also needs to decode SCI only one time to determine the D2D SPS resource. In this way, the first terminal does not need to determine a D2D SPS resource in each SC period, and the second terminal also does not need to decode SCI in each SC period to determine the D2D SPS resource. Therefore, D2D communication efficiency is improved.

Abstract: Embodiments provide an information processing method, user equipment, and a base station, where the information processing method includes: a terminal sends a random access preamble sequence according to a first coverage enhancement requirement corresponding to a first precision to a base station. The terminal receives a coverage enhancement requirement indication message, wherein the coverage enhancement requirement indication message indicates a second coverage enhancement requirement corresponding to a second precision from the base station. The terminal communicates with the base station according to the second coverage enhancement requirement.

Abstract: Embodiments of the present invention provide a network listening method and device, where the method includes: determining, by a first device according to a type of a network listening resource, a time-frequency pattern that is of a first sequence and is corresponding to the network listening resource of this type; and then transmitting the first sequence to a second device by using the time-frequency pattern of the first sequence, so that the second device performs network listening according to the first sequence. The time-frequency pattern of the first sequence determined in this process is a time-frequency pattern obtained by transforming a time-frequency pattern of a base sequence, and a network listening signal obtained therefrom, that is, the time-frequency pattern of the first sequence, is simple, which can achieve a purpose of reducing complexity of generating a network listening signal and computational complexity of parsing a network listening signal.
