The present disclosure relates to a resource allocation method and a terminal. The resource allocation method includes: transmitting, by a first terminal, first information to a second terminal. The first information instructs the second terminal to allocate a sidelink transmission resource to the first terminal. According to an embodiment of the present disclosure, the sidelink transmission resource is allocated by the terminal to reduce interference in sidelink transmissions of individual terminals. In addition, compared with applying for a transmission resource from a network, the method can reduce delay, shorten allocation time, and improve allocation efficiency.

Embodiments of the present disclosure provide a method for processing multiple resource conflicts and a terminal device, used for avoiding unnecessary resource transmission blocking and ensuring priority resource transmission. The method may comprise: when a target priority comparison mode is configured for a medium access control (MAC) entity, for each uplink grant, performing priority comparison between the uplink grant and a compared resource.

Certain aspects of the present disclosure provide techniques for communicating a dynamically scheduled transmission that overwrites a transmission in a semi-static scheduling occasion. A method performed by a user equipment (UE) includes receiving a first control message, activating a first semi-static scheduling configuration and a second semi-static scheduling configuration for full duplex communication, wherein: the first semi-static scheduling configuration comprises a semi-persistent scheduling (SPS) occasion and the second semi-static scheduling configuration comprises a configured grant (CG) occasion. The method may further include receiving a second control message dynamically scheduling a transmission that overwrites a downlink transmission in the SPS occasion or an uplink transmission in the CG occasion and taking one or more actions to communicate at least the transmission that overwrites the downlink transmission in the SPS occasion or the uplink transmission in the CG occasion.

Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE detects one or more conditions are met for transmitting a medium access control (MAC) control element (CE) providing assistance information to a network entity for scheduling. In response to the detection, the UE then takes one or more actions to obtain uplink (UL) resources for transmitting the MAC CE.

Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform uplink reference signal bundling for access link communications and transmit sidelink communications using time or frequency division multiplexed resources. The UE may determine to drop or to transmit a sidelink communication based on a relationship with multiple instances of an uplink reference signal that are to maintain phase continuity. The UE may drop a sidelink communication when a time duration between two instances of the uplink reference signal is less than or equal to a time threshold value, and may transmit the sidelink communication when the time duration exceeds the time threshold value. In frequency division multiplexed cases, the UE may set a transmission power for each instance of the uplink reference signal, and the sidelink communication may use a remaining amount of power.

A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be used for a second latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A first latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The first latency transmission can have a longer latency than the second latency transmission.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

A user equipment (UE) and a base station (BS) for a mobile communication system are provided. The UE receives, from the BS, a first downlink control information (DCI) indicating a first uplink resource for transmitting a first uplink signal, and then receives, from the BS, a second DCI indicating a second uplink resource for transmitting a second uplink signal. The BS configures the second uplink resource to be advanced to the first uplink resource in the time domain based on the uplink out-of-order configuration. The UE decides the transmission of the first uplink signal according to the condition of resource configuration.

A terminal according to one aspect of the present disclosure includes a receiving section that receives information indicating first priority of first uplink transmission and receives information indicating second priority of second uplink transmission, and a control section that controls, in a case where the first uplink transmission and the second uplink transmission overlap each other in time, the first uplink transmission and the second uplink transmission, based on at least one of a combination of the first priority and the second priority and a cell group of the first uplink transmission or the second uplink transmission. According to one aspect of the present disclosure, it is possible to appropriately control UL transmission even in a case where priority is configured for UL transmission.

A method for processing uplink transmission includes: in response to uplink transmission of a first priority and uplink transmission of a second priority overlapping in a time domain, determining a target time point, where the first priority is higher than the second priority; and cancelling the uplink transmission of the second priority after the target time point, where the target time point is determined at least partially according to an available time domain position of the uplink transmission of the first priority.
