User equipment configured for determining determination of HARQ process ID for higher carrier frequency when scheduled with multiple PUSCHs with overlapping symbols
Various embodiments herein provide techniques for determination of hybrid automatic repeat request (HARQ) process identifier (ID). The techniques may be used, for example, for multi-transmission scheduling by a single downlink control information (DCI) and/or in higher carrier frequencies. Other embodiments may be described and claimed.
1 . A User Equipment (UE) configured for operation in a fifth-generation new radio (5G NR) network, the UE comprising: processing circuitry; and memory, the processing circuitry configured to:
decode a downlink control information (DCI) format scheduling multiple physical uplink shared channels (PUSCHs) on a serving cell;
apply a hybrid automatic repeat request (HARQ) process identifier (ID) indicated by the DCI format to a first of the scheduled multiple PUSCHs that is not overlapping with a downlink (DL) symbol indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated if provided, or a symbol of an SS/PBCH block with an index provided by ssb-PositionsInBurst;
exclude one or more of the scheduled multiple PUSCHs from transmission if at least one symbol, indicated by an indexed row of a resource allocation table, in a slot overlaps with a DL symbol indicated by the tdd-UL-DL-ConfigurationCommon or the tdd-UL-DL-ConfigurationDedicated;
further exclude one or more of the scheduled PUSCHs from transmission if at least one symbol, indicated by the indexed row of the resource allocation table, in a slot overlaps with a symbol of the SS/PBCH block with the index provided by the ssb-PositionsInBurst;
configure the UE to transmit the scheduled multiple PUSCHs, that have not been excluded from transmission, in a scheduled order;
increment the HARQ process ID by one for each subsequent one of the multiple scheduled PUSCHs that is transmitted; and
refrain from incrementing the HARQ process ID for any of the one or more of the multiple scheduled PUSCHs that are excluded from transmission.
2 . The UE of claim 1 , wherein the processing circuitry is further configured to:
decode a second DCI format scheduling multiple physical downlink shared channels (PDSCHs) on the serving cell;
apply a first HARQ process ID indicated by the second DCI format to a first PDSCH that is not overlapping with an uplink (UL) symbol indicated by the tdd-UL-DL-ConfigurationCommon or the tdd-UL-DL-ConfigurationDedicated, if provided;
decode one or more of the PDSCHs received in a scheduled order,
wherein the first HARQ process ID is incremented by one for each subsequent PDSCH that is received in the scheduled order, and
wherein the first HARQ process ID is not incremented for a PDSCH that is not received if at least one of the symbols, indicated by the indexed row of a resource allocation table, in a slot overlaps with a UL symbol indicated the by tdd-UL-DL-ConfigurationCommon or the tdd-UL-DL-ConfigurationDedicated, if provided.
