An apparatus and method for uplink data transmission scheduling are disclosed. In an example, the method can include obtaining, by at least one processor, a plurality of packets to be transmitted via uplink. The method can also include queueing, by the at least one processor, the plurality of packets according to logical channel prioritization. The method can further include receiving, by the at least one processor, a service grant after the queueing. The method can additionally include trimming, by the at least one processor, the plurality of packets according to a grant size of the service grant.

Embodiments of apparatus and method for uplink grant handling are disclosed. In one example, a method for uplink grant handling can include receiving an uplink grant at a user equipment from a network device. The method can also include associating the uplink grant directly with a logical channel group including a plurality of logical channels. The user equipment can be configured to dequeue the logical channel group directly with priority for transmission scheduling. In some embodiments, the method can further include sending, to the network device from the user equipment, a request to associate a list of logical channel groups including the logical channel group. The request to associate can include a request to associate the plurality of logical channels with the logical channel group.

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive control signaling indicating a first semi-static configuration for transmitting uplink signaling and a second semi-static configuration for receiving downlink signaling. In some cases, the UE may operate using half-duplex communications and may monitor for a transmission direction conflict between the first semi-static configuration and the second semi-static configuration during a transmission time interval. The UE may communicate, according to a priority rule, one of an uplink signal in accordance with the first semi-static configuration or a downlink signal in accordance with the second semi-static configuration during the transmission time interval based on the monitoring. Additionally, or alternatively, the UE may drop one of the uplink signal or downlink signal according to the priority rule.

A method performed by a user equipment (UE) includes initiating a Small Data Transmission (SDT) procedure for transmitting a first set of data packets to a base station (BS) via an uplink (UL) transmission, determining, while the UE is in a Radio Resource Control (RRC) Inactive state, whether to prioritize the UL transmission over a sidelink (SL) transmission when there is a conflict between the UL transmission and the SL transmission during the SDT procedure, where the SL transmission is for transmitting a second set of data packets to another UE.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more messages indicative of uplink semi-persistent scheduling (SPS) resources and downlink SPS resources allocated to the UE, the uplink SPS resources and the downlink SPS resources being within a frequency band used for full duplex communications by the UE. The UE may modify parameters associated with the full duplex communications on the uplink SPS resources, the downlink SPS resources, or both, based at least in part on instances of the uplink SPS resources at least partially overlapping in time with instances of the downlink SPS resources. The UE may apply the one or more parameters, after modification, to transmission of uplink communications over the instances of the uplink SPS resources, reception of downlink communications over the instances of the downlink SPS resources, or both.

Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.

Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

A method, network node and wireless device that use grants that restrict the set of LCHs that can be serviced using the grant are disclosed. According to one aspect, a method in a wireless device (WD) configured to communicate with a network node is provided. The method includes receiving from the network node, a first grant for uplink transmission of data, the first grant indicating that use of the first grant is restricted to logical channels (LCHs) of a first subset of LCHs of an LCH set, the first subset of LCHs configured to include fewer than all LCHs, such that there exists at least one LCH for which use of the first grant is not allowed. The method also includes selecting at least one LCH from the first subset of LCHs according to a priority of LCHs in the first subset of LCHs, the selected at least one LCH configured to provide data to be transmitted on the uplink according to the first grant.

In one embodiment, an operation method of a relay UE in a wireless communication system is a method comprising: comparing a transmission priority value with a first priority value; and performing sidelink transmission/reception on the basis of the comparison result, wherein the transmission priority value is compared with a reception priority value on the basis of the fact that the transmission priority value is smaller than the first priority value, and an operation corresponding to a smaller value from among the transmission priority value and the reception priority value is performed.

A user equipment (UE) is described. The UE includes circuitry configured to determine that a physical uplink control channel (PUCCH) with low priority (LP) overlaps with a high priority (HP) PUCCH carrying a HP hybrid automatic repeat request-acknowledgement (HARQ-ACK) and a HP PUCCH with a positive HP scheduling request (SR). The HP PUCCH with HP HARQ-ACK does not overlap with the HP PUCCH with the positive HP SR. The circuitry is further configured to multiplex a LP HARQ-ACK only with the HP HARQ-ACK.
