Abstract
A user equipment (UE), a base station, and methods of identifying the UE are provided. The method of identifying the UE performed by the UE includes determining, by the UE from the base station, a configuration associated with the UE and performing, by the UE, a random access (RA) procedure using the configuration associated with the UE, wherein a UE type of the UE is identified in the RA procedure by the base station. This can solve issues in the prior art, reach early identification of the UE, realize coverage compensation, provide different schedules for different UE types, provide a good communication performance, and/or provide high reliability.
Claims20
A method of identifying a user equipment (UE) performed by the UE, comprising:
- performing, by the UE, a random access (RA) procedure, wherein an identification information associated with a UE type of the UE is carried in an uplink message of the RA procedure;
- and
- wherein the UE type of the UE is identified based on the identification information by a base station;
- wherein the identification information associated with the UE type is a dedicated LCID of a MAC control element (MAC CE), and the MAC CE is carried on a MSGA, or a MSG3, or a post MSG4, or a MSG5, or a UE capability information, or a security mode complete, or a UL information transfer, or a UE information response, or a measurement report.
A user equipment (UE) comprising:
- a memory;
- a transceiver;
- and
- a processor coupled to the memory and the transceiver;
- wherein the processor is configured to perform a random access (RA) procedure, wherein an identification information associated with a UE type of the UE is carried in an uplink message of the RA procedure, and the UE type of the UE is identified based on the identification information by a base station;
- wherein before the processor performs the RA procedure, the transceiver receives a configuration associated with the UE comprising at least one of the followings:
- a configuration of physical random access channel (PRACH) resources, a configuration of an initial uplink bandwidth part, BWP, or a configuration of a random access preamble;
- wherein the configuration of the first RA preamble comprises CBRA preambles, and the CBRA preambles comprises a group A and a group B;
- wherein the CBRA preambles and the CFRA preambles of the Redcap UE are interlaced with or separated from CBRA preambles and CFRA preambles of another UE.
A method of identifying a user equipment (UE) performed by the UE, comprising:
- performing, by the UE, a random access (RA) procedure, wherein an identification information associated with a UE type of the UE is carried in an uplink message of the RA procedure;
- and
- wherein the UE type of the UE is identified based on the identification information by a base station;
- wherein before performing the RA procedure, the method further comprising:
- receiving, by the UE, a configuration associated with the UE comprising at least one of the followings:
- a configuration of physical random access channel (PRACH) resources, a configuration of an initial uplink bandwidth part, BWP, or a configuration of a random access preamble;
- wherein the configuration of the first RA preamble comprises CBRA preambles, and the CBRA preambles comprises a group A and a group B;
- wherein the CBRA preambles and the CFRA preambles of the Redcap UE are interlaced with or separated from CBRA preambles and CFRA preambles of another UE;
- wherein M fields are introduced to partition the group A of the CBRA preambles, the group B of the CBRA preambles, and the CFRA preambles into sections of the Redcap UE and the regular UE, respectively, and a number of M is related to a number of Redcap UE types or one Redcap UE type.
