Enhancement of logical channel prioritization for sidelink transmission
A method to prioritize sidelink logical channel (SL LCH) during destination UE selection for sidelink Logical Channel Prioritization (LCP) procedure in NR sidelink communication is proposed to avoid resource starvation. A TX UE prioritizes an RX UE having at least one SL LCH that has not satisfied a required minimum bit rate during destination UE selection when allocating SL resource to a new MAC PDU for SL transmission. The TX UE maintains a value Bj for each SL LCH j, where Bj>0 indicates that the logical channel has not met the requirement of prioritized bit rate. If at least one destination UE has SL LCH with data available for transmission and with Bj>0, then the selected destination UE is the one has the highest-priority SL LCH with data available for transmission and with Bj>0.
Fair Distribution Of Radio Resources Between Guaranteed Bit Rate (GBR) And Non-GBR Data Bearers
User equipments (UEs) may be scheduled by determining relative priorities of data radio bearers (DRBs), each DRB associated with a respective UE. A limit is established dividing radio resources available for allocation in the cell during a scheduling period into at least a first limited portion and a second remaining portion. According to the determined relative priorities: a) up to the first limited portion of the radio resources are allocated to only the DRBs that have a guaranteed bit rate (GBR), and thereafter b) the second remaining portion of the radio resources are allocated to only the DRBs which have not been fully allocated from the first limited portion. Schedules indicating this allocation are transmitted to the respective UEs. In carrier aggregation where each carrier aggregated cells has a respective plurality of DRBs, relative priorities for each respective plurality of DRBs are determined for each carrier aggregated cell.
Systems and methods for bandwidth part selection initiated by a user equipment
A user equipment transmits user equipment information, associated with a communication of the user equipment, to permit a base station to select a first bandwidth part, a second bandwidth part, or a third bandwidth part. The user equipment is configured to communicate by the first bandwidth part, the second bandwidth part, and the third bandwidth part. The user equipment receives, from the base station, an instruction to monitor the first bandwidth part, the second bandwidth part, or the third bandwidth part. The instruction is selected based on the user equipment information. The user equipment monitors, based on the instruction, the first bandwidth part, the second bandwidth part, or the third bandwidth part.
Limiting an aggregate bit rate by ignoring duplicated PDCP packets
A first base station receives an aggregate maximum bit rate of a wireless device; and an indication of packet data convergence protocol (PDCP) duplication for a bearer. Duplicated PDCP packets of the bearer are received from a PDCP layer of a second base station. The duplicated PDCP packets are transmitted to the wireless device via the bearer. An aggregate bit rate between the wireless device and the first base station is limited based on the aggregate maximum bit rate. The aggregate bit rate is determined while ignoring the duplicated PDCP packets.

This application provides a scheduling method and an apparatus. The method includes: determining, by an application processor, a type of a to-be-sent data packet, and putting, by the application processor, the to-be-sent data packet into a quality of service QoS data flow corresponding to the type of the to-be-sent data packet, where the type of the to-be-sent data packet is a GBR type or a non-GBR type; and scheduling, by the application processor, a to-be-sent data packet in a QoS data flow corresponding to the GBR type to send the to-be-sent data packet to a modem in a terminal in which the application processor is located, and after determining that a data transmission rate requirement of the GBR type is met, scheduling, by the application processor, a to-be-sent data packet in a QoS data flow corresponding to the non-GBR type to send the to-be-sent data packet to the modem.
Procedures for managing quality of service flows
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink data associated with a first quality of service flow is available for transmission to a base station. The UE may transmit a buffer status report to the base station. In some examples, the buffer status report may include a buffer status of the first quality of service flow. The UE may then receive an uplink grant based on transmitting the buffer status report, and may transmit the uplink data based on the uplink grant.
