The present application relates to devices and components including apparatus, systems, and methods for reporting random access configuration information in wireless networks.

In embodiment methods for managing uplink spatial filter configuration, comprising, a processor of a wireless device may send an initial access signal using two or more spatial filters, wherein each spatial filter directs a beam to a respective uplink (UL) receive (Rx) point, receive from the base station an indication of which beam to use for UL transmissions, and send to the base station another signal using the spatial filter corresponding to the indicated beam. A base station may receive the initial access signal via two or more UL Rx points on two or more beams, determine which of the two or more beams provides a better received signal, send an indication of the better of the two or more beams to the wireless device, and receive from the wireless device another signal on the indicated better of the two or more beams via a corresponding UL Rx point.

This application provides a random access method and apparatus. The method may include determining, by a terminal, a service attribute of to-be-transmitted data, where the service attribute includes one or more of the following: a service type attribute, a service packet attribute, and a service latency attribute. The method may also include sending, by the terminal when the service attribute meets a preset condition for early data transmission, a random access request to a network device using a dedicated resource for the early data transmission. In this way, the early data transmission is initiated after the service attribute meets the preset condition for the early data transmission, so that a quantity of times for which the early data transmission is initiated is reduced, thereby saving resources. In addition, a success rate of the early data transmission can be improved.

A random access method, a terminal and a network device are provided. The random access method includes: sending a random access request carrying a first identifier, or sending a random access request and a first identifier.

The present disclosure provides a grant free uplink transmission method, the method is performed at a user equipment side, comprising: determining, according to configuration information for grant free uplink transmission received from a base station, a radio network temporary identifier GF-RNTI for grant free uplink transmission, and transmitting an uplink signal; and monitoring feedback from the base station in a downlink control channel by using the determined GF-RNTI. The present disclosure also provides a user equipment and a base station for grant free uplink transmission.

Methods, apparatuses and systems are provided for transmitting data. A method includes: sending a target random access preamble to a base station; receiving a target random access response that is sent by the base station based on the target random access preamble and carries repetition-number-indicating information; and transmitting, in accordance with a target transmission repetition number, the target uplink data to the base station during the random access procedure. The target transmission repetition number indicates a number of times the user equipment is configured to repeatedly transmit the target uplink data to the base station during the random access procedure. The target transmission repetition number is determined based on the repetition-number-indicating information and a target transmission block size. The target transmission block size is for the user equipment to transmit the target uplink data to the base station during the random access procedure.

According to some embodiments, a method for use in a user equipment (UE) of managing a listen-before-talk (LBT) contention window size comprises transmitting a first burst of uplink subframes after a first LBT procedure performed using an LBT contention window size, and determining a reference subframe based on the first burst. The reference subframe is associated with a reference hybrid automatic repeat request (HARQ) process identifier. The method further comprises receiving scheduling for a second burst of uplink subframes. The scheduling comprises an associated HARQ process identifier and an associated new data indicator (NDI) for each subframe. When the UE determines the HARQ process identifier associated with at least one of the subframes of the second burst matches the reference HARQ process identifier, then if the associated NDI indicates new data, the method resets the LBT contention window size, else the method increments the LBT contention window size.

Systems and methods for storing and transmitting random access (RA) information related to one or more RA procedures is discussed herein. In one embodiment, the systems and methods are configured to storing, by a wireless communication device , RA information of multiple sets of RA resource of a completed RA procedure. The method further includes receiving, by the wireless communication device from a wireless communication node , an indicator via a radio resource control (RRC) message. The method also includes transmitting, by the wireless communication device to the wireless communication node, responsive to the indicator, the RA information of the multiple sets of RA resource of the completed RA procedure.

A method for wireless communication between a plurality of devices includes determining the number of PUSCH repetition transmissions, determining a PUSCH transmission resource, based on random access-related configuration information and the number of PUSCH repetition transmissions, and performing the PUSCH repetition transmission based on the PUSCH transmission resource.

Wireless communications may be used for repetition of one or more transmissions. At least some wireless devices may use and/or require different quantities of repetitions of one or more transmissions based on one or more factors such as received signal strength and/or other channel condition(s). The quantity of repetitions may be less than or equal to a maximum quantity of repetitions that may be indicated by a base station.
