Embodiments of the present disclosure relate to methods, devices and computer readable media for communications. A method comprises determining, at a first terminal device, whether to obtain information about candidate resources for a sidelink transmission. The method further comprises in response to a determination that the information is to be obtained, receiving the information from a second terminal device. The method further comprises determining target resources for performing the sidelink transmission based on the information.

Methods, devices and computer readable media for communications on a sidelink

Embodiments of the present disclosure relate to devices, methods, devices and computer readable storage media for resource selection in a Vehicle to Everything (V2X) communication. The method comprises determining, at a terminal device, a resource reservation period for at least one sidelink transmission; and in accordance with a determination, based on the resource reservation period, that a reference resource associated with the at least one sidelink transmission is subsequent to a sensing window, determining, from a resource selection window of the terminal device, at least one further reference resource to be reserved for the at least one sidelink transmission based on the resource reservation period. In this way, the conflict of resource selection can be avoided and therefore the performance of the sidelink transmission can be improved.

Methods for communication, terminal device, and computer readable media

Embodiments of the present disclosure provide a solution for sidelink discontinuous reception (DRX). In a method for communication, a first terminal device of terminal devices in a communication network obtains a sidelink DRX configuration. The first terminal device determines, from the sidelink DRX configuration, a sidelink DRX cycle including a first duration during which sidelink communications are allowed to be performed among the terminal devices and a second duration during which the sidelink communications are not allowed to be performed. The first terminal device performs, during the first duration, a sidelink communication with a second terminal device of the terminal devices. With the embodiments of the present disclosure, terminal devices can efficiently communicate with each other using sidelink DRX operations.

Methods for communication, terminal device, network device, and computer readable media

Embodiments of the present disclosure relate to methods, devices and computer readable media for resource selection. In example embodiments, a method for resource selection includes selecting, at a first terminal device, a first resource for transmitting a first packet from a resource pool. The method further includes determining a second resource selected from the resource pool by a second terminal device for transmitting a second packet. The method further includes determining whether a first transmission priority associated with the first packet is lower than a second transmission priority associated with the second packet. The method further includes in response to determining that the first transmission priority is lower than the second transmission priority, selecting an available resource from the resource pool to transmit the first packet.

Method, device and computer readable medium for resource selection

Embodiments of the present disclosure relate to a method, network device, and apparatus for transmitting a preemption indication and a method, terminal device, and apparatus for receiving a preemption indication. In an embodiment of the present disclosure, the method of transmitting a preemption indication may comprise transmitting a preemption indication to a terminal device, wherein the preemption indication indicates information on a portion of resources allocated to a first transmission which is preempted by a second transmission, and wherein the preemption indication is associated with information on structure of the current slot. In embodiments of the present disclosure, by means of information on structure of a subframe, the indication monitoring and overhead for the preemption indication can be reduced remarkably, thereby providing a much more efficient preemption indication solution.

Embodiments of the present disclosure relate to methods, devices and apparatus for resource allocation for a control resource region in a wireless communication system. In an embodiment of the present disclosure, a method may include determining resource units each containing a predetermined number of resource blocks based on available transmission resources. Resource blocks not contained in the resource units are distributed in the available transmission resources to divide resource blocks contained in the resource units into a plurality of resource segments. The method also comprise allocating one or more of the determined resource units to the control resource region and transmitting resource allocation information indicating the allocated one or more of resource units. With embodiments of the present disclosure, there is provided an effective solution for resource allocation for control resource region.

Methods and devices for resource allocation for control resource region

Embodiments of the present disclosure relate to a method, terminal device and apparatus for physical random access channel (PRACH) power control and a method, network device and apparatus for transmitting parameters of PRACH power control. In an embodiment of the present disclosure, the method of PRACH power control may comprise determining a transmission power of PRACH preamble based on a power constriction of a terminal device, a preamble received target transmission power and a downlink path loss on a beam level. With embodiments of the present disclosure, it could provide a power control for PRACH with improved accuracy, which increases the success possibility of random access attempt and interferences to other devices.

Embodiments of the present disclosure relate to methods and apparatuses for control resource mapping. In example embodiments, a method implemented in a communication device is provided. According to the method, REG indices for a plurality of REGs are obtained in a control channel region. The REG bundle indices are determined based on the REG indices and a pattern of REG bundle. The pattern of REG bundle indicates the number of REGs in the frequency domain and the number of OFDM symbols in the time domain. CCE indices are determined based on the determined REG bundle indices and the number of CCEs in the control channel region. The CCE indices are continuous with respect to the REG bundle in the frequency domain.
