摘要： Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

摘要： A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

摘要： Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a first set of grants for performing uplink transmissions between the UE and a first group of cells associated with a first radio access technology (RAT) and a second set of grants for performing uplink communication between the UE and a second group of cells associated with a second RAT. The UE may determine that a combined transmit power exceeds a total power limit or that there may be a potential of the combined power exceeding the total power limit. The UE may further perform the uplink communication with the first group of cells using the first RAT and the second group of cells using the second RAT.

摘要： The present methods and apparatus relate to wireless communications at either a user equipment (UE) or a network entity in a new radio communication system. The described aspects include receiving, via a communication channel, a scheduling grant from a transmitting wireless device, the scheduling grant including a Resource Indication Value (RIV) corresponding to an allocation of resource blocks (RBs) for communicating on the communication channel. The described aspects further include mapping the RIV to a constrained set of one or more RBs to identify allocated RBs, the constrained set of one or more RBs including a fewer number of RBs than a number of available RBs in a slot or transmission duration. The described aspects further include communicating, with the transmitting wireless device via the communication channel, using the allocated RBs from the constrained set of one or more RBs as signaled by the RIV.

摘要： Techniques are described for wireless communication at a wireless communication device. A determination may be made regarding the number of receive chains, of a plurality of receive chains, to enable for a channel. Power to the receive chains may be regulated based on the determined number of enabled receive chains. The determination may be based on a transmission scheduling rate for the wireless communication device and a rank for the channel. In some examples, the determination may further be based on a channel quality of the channel and/or a type of traffic scheduled for the channel.

摘要： Methods, systems, and devices are described for wireless communication. A user equipment (UE) may signal a band-specific measurement gap indication based on the capability of a set of receivers to measure target frequency bands while monitoring a set of component carriers (CCs). The UE may receive a measurement gap configuration for a first component carrier (CC) associated with measuring the target frequency bands accounting for the band-specific measurement gap indication. The UE may then perform a measurement on one or more of the target frequency bands according to the measurement gap configuration while continuing to monitor other configured CCs for downlink messages and transmit uplink control messages during gaps configured for the first CC (e.g., using a different receiver). In some examples the measurement gap configuration message includes configuration options and the UE may select the measurement gap configuration for the first CC from the set of available options.

摘要： Methods, systems, and devices for wireless communications are described. The described techniques provide for selecting a PRACH occasion (RO) based on downlink quality, access congestion, latency (e.g., time to next available RO), beam correspondence, random access in previous transmissions, or combinations of these factors. The user equipment (UE) may detect access congestion of synchronization signal blocks (SSBs) and select the less congested SSB in the RO selection. The UE may detect the access congestion by receiving a back-off indicator from the base station, detecting a contention resolution failure, or the number or media access control (MAC) subheaders in a random access response. In some cases, the ROs associated with different SSBs have different latencies and the UE may select the earliest available RO.

摘要： Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once. Collisions may be resolved by dropping or rescheduling overlapping information from the lower priority transmission(s) or channel(s) in consideration of the higher priority transmission(s) or channel(s), or by multiplexing or piggybacking overlapping information from a first priority transmission(s) or channel(s) with a second priority transmission(s) or channel(s).

摘要： In an aspect, a UE determines whether there is an overlap between a first uplink transmission channel allocated for transmission of a first uplink transmission and a second uplink transmission channel allocated for transmission of second uplink transmission. The UE generates a combined uplink transmission payload in response to a determination that there is the overlap, wherein the combined uplink transmission payload includes at least a portion of the first uplink transmission and at least a portion of the second uplink transmission. The UE transmits the combined uplink transmission payload on either the first uplink transmission channel or the second uplink transmission channel. A base station receives the combined uplink transmission payload transmitted by the UE.
