Abstract
Techniques and devices for wireless communications are described. A base station may indicate to a user equipment (UE) repetition parameters for an uplink message using transmission parameters in a response message of a random access channel (RACH) procedure. In some examples, the base station may transmit system information to the UE configuring a mapping between the transmission parameters and the repetition parameters, for example based on a repetition request or a capability indication in a random access request from the UE. The indications in the response message configuring uplink message repetitions may enable increased system efficiency and reduced latency at the UE, among other benefits.
Claims27
A method for wireless communications at a user equipment (UE), comprising:
- receiving a system information block identifying a mapping between a first transmission parameter associated with transmissions from the UE and a repetition parameter associated with an uplink message;
- transmitting a random access request to establish a connection with a network entity;
- receiving, in response to transmitting the random access request, a random access response including control signaling transmitted with one or more transmission parameters associated with transmissions from the UE, wherein the one or more transmission parameters comprises the first transmission parameter, wherein the first transmission parameter maps to the repetition parameter associated with the uplink message in accordance with the received system information block;
- and
- transmitting, based at least in part on the first transmission parameter mapping to the repetition parameter in accordance with the received system information block, one or more repetitions of the uplink message according to the repetition parameter.
An apparatus for wireless communications at a user equipment (UE), comprising:
- one or more processors;
- memory coupled with the one or more processors;
- and
- instructions stored in the memory and executable by the one or more processors to cause the apparatus to:
- receive a system information block identifying a mapping between a first transmission parameter associated with transmissions from the UE and a repetition parameter associated with an uplink message;
- transmit a random access request to establish a connection with a network entity;
- receive, in response to transmitting the random access request, a random access response including control signaling transmitted with one or more transmission parameters associated with transmissions from the UE, wherein the one or more transmission parameters comprises the first transmission parameter, wherein the first transmission parameter maps to the repetition parameter associated with the uplink message in accordance with the received system information block;
- and
- transmit, based at least in part on the first transmission parameter mapping to the repetition parameter in accordance with the received system information block one or more repetitions of the uplink message according to the repetition parameter.
A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by one or more processors to:
- receive a system information block identifying a mapping between a first transmission parameter associated with transmissions from the UE and a repetition parameter associated with an uplink message;
- transmit a random access request to establish a connection with a network entity;
- receive, in response to transmitting the random access request, a random access response including control signaling transmitted with one or more transmission parameters associated with transmissions from the UE, wherein the one or more transmission parameters comprises the first transmission parameter, wherein the first transmission parameter maps to the repetition parameter associated with the uplink message in accordance with the received system information block;
- and
- transmit, based at least in part on the first transmission parameter mapping to the repetition parameter in accordance with the received system information block, one or more repetitions of the uplink message according to the repetition parameter.
An apparatus for wireless communications at a user equipment (UE), comprising:
- means for receiving a system information block identifying a mapping between a first transmission parameter associated with transmissions from the UE and a repetition parameter associated with an uplink message;
- means for transmitting a random access request to establish a connection with a network entity;
- means for receiving, in response to transmitting the random access request, a random access response including control signaling transmitted with one or more transmission parameters associated with transmissions from the UE, wherein the one or more transmission parameters comprises the first transmission parameter, wherein the first transmission parameter maps to the repetition parameter associated with the uplink message in accordance with the received system information block;
- and
- means for transmitting, based at least in part on the first transmission parameter mapping to the repetition parameter in accordance with the received system information block, one or more repetitions of the uplink message according to the repetition parameter.
