Systems and methods for an enhanced scheduling request for 5G NR
A 5G new radio (NR) Base Station (gNB) is described. The gNB includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to send a radio resource control (RRC) message to a user equipment (UE). The RRC message(s) includes different physical uplink control channel (PUCCH) configuration options and/or SR-configurations, comprising one or more of the following information elements (IE), i.e., Bandwidth, Numerology, BWP, Logical Channel (LCH), priority, LCG, Service, etc., for the UE to use in transmitting one or more scheduling requests (SR).
1. A user equipment comprising:
receiving circuitry configured to receive, from a base station apparatus, a radio resource control (RRC) message(s) comprising more than one scheduling request (SR) configuration, bandwidth part (BWP) identifier(s) indicating one or more BWPs, and one or more BWP configuration used for indicating uplink frequency location, uplink BW size, and numerology; and
transmitting circuitry configured to transmit, to the base station apparatus, SR on a physical uplink control channel (PUCCH) based on the one or more BWPs indicated by the BWP identifier(s); wherein
each SR configuration is associated with a set of PUCCH resources for SR across different bandwidths in frequency domain and is corresponding to the following:
one or more logical channel groups (LCG),
one or more priorities, and
one or more subcarrier spacings.
2. A base station apparatus comprising:
transmitting circuitry configured to transmit, to a user equipment, a radio resource control (RRC) message(s) comprising more than one scheduling request (SR) configurations and bandwidth part (BWP) identifier(s) indicating one or more BWPs, wherein the BWP configuration is used for indicating uplink frequency location, uplink BW size, and numerology; and
receiving circuitry configured to receive, from the user equipment, SR on a physical uplink control channel (PUCCH) based on the one or more BWPs indicated by the BWP identifier(s); wherein
each SR configuration is associated with a set of PUCCH resources for SR across different bandwidths in frequency domain and is corresponding to the following:
one or more logical channel groups (LCG),
one or more priorities, and
one or more subcarrier spacings.
3. A method of a user equipment, the method comprising:
receiving, from a base station apparatus, a radio resource control (RRC) message(s) comprising more than one scheduling request (SR) configurations and bandwidth part (BWP) identifier(s) indicating one or more BWPs, wherein the BWP configuration is used for indicating uplink frequency location, uplink BW size, and numerology; and
transmitting, to the base station apparatus, SR on a physical uplink control channel (PUCCH) based on the one or more BWPs indicated by the BWP identifier(s); wherein
each SR configuration is associated with a set of PUCCH resources for SR across different bandwidths in frequency domain and is corresponding the following:
one or more logical channel groups (LCG),
one or more priorities, and
one or more subcarrier spacings.
4. A method of a base station apparatus, the method comprising:
transmitting, to a user equipment, a radio resource control (RRC) message(s) comprising more than one scheduling request (SR) configurations and bandwidth part (BWP) identifier(s) indicating one or more BWPs, wherein the BWP configuration is used for indicating uplink frequency location, uplink BW size, and numerology; and
receiving, from the user equipment, SR on a physical uplink control channel (PUCCH) based on the one or more BWPs indicated by the BWP identifier(s); wherein
each SR configuration is associated with a set of PUCCH resources for SR across different bandwidths in frequency domain and is corresponding to the following:
one or more logical channel groups (LCG),
one or more priorities, and
one or more subcarrier spacings.
