Abstract
A method and a user equipment (UE) are provided for resource allocation. The UE receives repeated physical downlink control channels (PDCCHs) from a network. Each of the repeated PDCCHs includes downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE determines resources for at least one of transmission and reception at the UE, from a PDCCH having a latest start symbol or a latest ending symbol among the repeated PDCCHs. The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.
Claims20
A method for resource allocation by a user equipment (UE):
- receiving, at the UE, repeated physical downlink control channels (PDCCHs) from a network, each of the repeated PDCCHs comprising downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE;
- and
- determining, by the UE, resources for:
- transmission at the UE based on an indicator from a PDCCH having a latest start symbol or a latest ending symbol from among the repeated PDCCHs, and
- reception at the UE based on an offset after the PDCCH, wherein the PDCCH having the latest start symbol or the latest ending symbol from among the repeated PDCCHs,
- wherein the repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission and reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.
A user equipment (UE) comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing instructions that, when executed, cause the processor to:
- receive repeated physical downlink control channels (PDCCHs) from a network, each of the repeated PDCCHs comprising downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE;
- and
- determine resources for:
- transmission at the UE based on an indicator from a PDCCH having a latest start symbol or a latest ending symbol from among the repeated PDCCHs, and
- reception at the UE based on an offset after the PDCCH having the latest start symbol or the latest ending symbol from among the repeated PDCCHs,
- wherein the repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission and reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.
