Abstract: Systems and methods for wireless communications are disclosed herein. In one embodiment, a wireless communication device determines that a first resource indicated by uplink cancelation information overlaps with a second resource. The wireless communication device receives, from a network, an uplink (UL) grant scheduling a third resource. An ending symbol of a first downlink control channel carrying the UL grant is no earlier than a first symbol of a second downlink control channel carrying the uplink cancelation information.

Abstract: Techniques are described to configure a channel structure for a random-access procedure. For example, a wireless communication method includes communicates, by a first device, a channel structure to a second device, where the channel structure includes a first set of resources reserved for a first message (e.g., a preamble), a second set of resources reserved for a second message (e.g., a payload), or a time duration gap between the first set of resources and the second set of resources. The wireless communication method also includes receiving by the first device the first message and the second message at the configured first and second set of resources, respectively

Abstract: Techniques are described to determine timing advance amount. For example, a first device receives, from a second device, a message comprising one or more fields that include information indicative of a communication delay between the first device and the second device. The first device processes the message to use the information for a transmission between the second device and the first device.

Abstract: Provided are a method and device for sending or acquiring a grant signalling. The method for sending a grant signalling includes: configuring one Multi-Physical Downlink Control Channel (M-PDCCH); and sending a grant signalling to N pieces of User Equipment (UE) through the M-PDCCH. By the technical solution, the technical problem that data throughput and spectral efficiency of a system are reduced by higher PDCCH overhead caused by the fact that one PDCCH or EPDCCH signalling can be granted to only one piece of UE in the related technology is solved, and the technical effect of improving the data throughput and spectral efficiency of the system is achieved.
