Abstract
A user equipment, UE, comprising at least one processor, and memory storing instructions that, when executed by the at least one processor, cause the UE at least to determine how to use resources of a repetition-based uplink grant based on a criterion related to at least one data packet prepared for a transmission on resources associated with the repetition-based uplink grant.
Claims20
A user equipment, UE, comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the UE at least to:
- provide a first data packet (MAC PDU) for transmission on a first resource (RES-0) of a repetition-based uplink grant (RB-UG);
- and
- determine how to use resources of the repetition-based uplink grant (RB-UG), including determining whether to repeat transmission of the first data packet or to generate at least one new data packet for transmission on at least one subsequent resource of the repetition-based uplink grant (RB-UG), wherein the determining is performed autonomously by the UE without requiring a new uplink grant or repetition instruction from a base station, based on at least one criterion (CRIT) selected from a group consisting of:
- a) a logical channel (LCH) mapped to the data packet or a preconfigured subset of LCHs;
- b) presence or type of medium access control (MAC) control elements (CE) mapped to the data packet and the LCHs the MAC CEs relate to;
- c) presence of signaling radio bearer (SRB) service data units (SDUs);
- d) quality of service (QoS) parameters including at least one of a QoS Flow Identifier (QFI), Packet Delay Budget (PDB), or survival time;
- e) availability of higher-priority data compared to the data packet;
- f) availability of data from a certain LCH or a certain MAC CE;
- g) a MAC entity;
- and
- h) a configured grant (CG) configuration;
- and
- when generating the at least one new data packet, use a subset of the resources of the repetition-based uplink grant (RB-UG) for the new transmission, the subset being indicated by a configuration message or implicitly by a redundancy version (RV) configuration.
14 more elements
A base station, comprising:
- at least one processor, and
- at least one memory storing instructions that, when executed by the at least one processor, cause the base station at least to:
- transmit a first configuration message (CM1) indicating a subset (SS-RES) of resources (RES-0, RES-1, RES-2, RES-3) of a repetition-based uplink grant (RB-UG) a user equipment, UE, may use for a new transmission;
- and
- configure the UE with at least one criterion (CRIT) based on which the UE autonomously determines how to use resources of the repetition-based uplink grant (RB-UG) without requiring a new uplink grant or repetition instruction from the base station, the at least one criterion (CRIT) being selected from a group consisting of:
- a) a logical channel (LCH) mapped to a data packet or a preconfigured subset of LCHs;
- b) presence or type of medium access control (MAC) control elements (CE) mapped to the data packet and the LCHs the MAC CEs relate to;
- c) presence of signaling radio bearer (SRB) service data units (SDUs);
- d) quality of service (QoS) parameters including at least one of a QoS Flow Identifier (QFI), Packet Delay Budget (PDB), or survival time;
- e) availability of higher-priority data compared to the data packet;
- f) availability of data from a certain LCH or a certain MAC CE;
- g) a MAC entity;
- and
- h) a configured grant (CG) configuration.
