Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling from a base station including a configuration for multiple transmission time intervals (TTIs) including uplink symbols, downlink symbols, flexible symbols, or a combination. The UE may receive a grant scheduling one or more repetitions of an uplink shared channel carrying an uplink random access message from the base station. The UE may determine available TTIs for the repetitions based on a pre-TTI evaluation of symbols according to a rule that defines types of symbols available for the uplink shared channel. The UE may transmit the repetitions on the available TTIs according to the rule.
Claims26
A method for wireless communications at a user equipment (UE), comprising:
- receiving a configuration for a plurality of transmission time intervals that each include either uplink symbols, downlink symbols, flexible symbols, or combinations thereof, wherein a flexible symbol is configurable as either an uplink symbol or a downlink symbol;
- receiving a grant scheduling one or more repetitions of an uplink shared channel to carry an uplink random access message;
- and
- transmitting the one or more repetitions on one or more corresponding transmission time intervals of the plurality of transmission time intervals in accordance with a rule, the one or more corresponding transmission time intervals each comprising a combination of one or more consecutive uplink symbols and one or more consecutive flexible symbols, the rule defining that both uplink symbols and at least a subset of the flexible symbols are available for the uplink shared channel.
A method for wireless communications at a network device, comprising:
- transmitting a configuration for a plurality of transmission time intervals that each include either uplink symbols, downlink symbols, flexible symbols, or combinations thereof, wherein a flexible symbol is configurable as either an uplink symbol or a downlink symbol;
- transmitting a grant scheduling one or more repetitions of an uplink shared channel to carry an uplink random access message;
- and
- receiving the one or more repetitions on one or more corresponding transmission time intervals of the plurality of transmission time intervals in accordance with a rule, the one or more corresponding transmission time intervals each comprising a combination of one or more consecutive uplink symbols and one or more consecutive flexible symbols, the rule defining that both uplink symbols and at least a subset of the flexible symbols are available for the uplink shared channel.
An apparatus for wireless communications at a user equipment (UE), comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive a configuration for a plurality of transmission time intervals that each include either uplink symbols, downlink symbols, flexible symbols, or combinations thereof, wherein a flexible symbol is configurable as either an uplink symbol or a downlink symbol;
- receive a grant scheduling one or more repetitions of an uplink shared channel to carry an uplink random access message;
- and
- transmit the one or more repetitions on one or more corresponding transmission time intervals of the plurality of transmission time intervals in accordance with a rule, the one or more corresponding transmission time intervals each comprising a combination of one or more consecutive uplink symbols and one or more consecutive flexible symbols, the rule defining that both uplink symbols and at least a subset of the flexible symbols are available for the uplink shared channel.
