Abstract
Methods and apparatuses are disclosed for random access channel (RACH) report enhancements. In one example embodiment, a user equipment (UE) may be configured to implement operations including: receiving a set of preamble configurations associated with features from a network; selecting a preamble from the set of preamble configurations; and transmitting the selected preamble to initiate random access with the network utilizing RACH partitioning to use a feature.
Claims30
A user equipment (UE) to connect to a network comprising:
- at least one antenna;
- at least one radio, wherein the at least one radio is configured to communicate with the network including a base station using the at least one antenna;
- and
- at least one processor coupled to the at least one radio, wherein the at least one processor is configured to perform operations comprising:
- receiving a set of preamble configurations associated with features from the network;
- selecting a preamble from the set of preamble configurations;
- and
- transmitting the selected preamble to initiate random access with the network utilizing random access channel (RACH) partitioning to use a feature.
The UE of claim 3, wherein the features include at least one of:
- reduced capability (RedCap) features, small data transmission (SDT) features, coverage enhancements features, slice grouping features, or non-terrestrial networks (NTN) features.
A baseband processor of a wireless user equipment (UE) of a network comprising:
- receiving a set of preamble configurations associated with features from the network;
- selecting a preamble from the set of preamble configurations;
- and
- transmitting the selected preamble to initiate random access with the network utilizing random access channel (RACH) partitioning to use a feature.
A base station of a communication network, comprising:
- at least one antenna;
- at least one radio, wherein the at least one radio is configured to communicate with a communication network using the at least one antenna;
- and
- at least one processor coupled to the at least one radio, wherein the at least one processor is configured to perform operations comprising:
- transmitting a set of preamble configurations associated with features from the communication network;
- receiving a selected preamble from a user equipment (UE) initiating random access utilizing random access channel (RACH) partitioning;
- and
- when the random access connection is successful, receiving an indication that the UE intends to use the selected feature.
A baseband processor of a base station of a network configured to perform operations comprising:
- transmitting a set of preamble configurations associated with features from the communication network;
- receiving a selected preamble from a user equipment (UE) initiating random access utilizing random access channel (RACH) partitioning;
- and
- when the random access connection is successful, receiving an indication that the UE intends to use the selected feature.
A method to enable the use of features by a user equipment (UE) in a network comprising:
- receiving a set of preamble configurations associated with features from the network;
- selecting a preamble from the set of preamble configurations;
- and
- transmitting the selected preamble to initiate random access with the network utilizing random access channel (RACH) partitioning to use a feature.
