A random access method, a base station, an UE and a device with a storage function are disclosed. The random access method includes: the base station receiving a first message transmitted by the UE, the first message including a preamble message and a signal message; decoding the preamble message and the signal message respectively; if the decoding of preamble message is succeeded, but the decoding of signal message fails, the base station transmits a second message to the UE, and storing the signal message of decoding failure, the second message configured to request the UE to retransmit the signal message; receiving the third message transmitted by the UE, the third message including the signal message; using a chase combine mechanism to decode the third message according to the stored signal message in the first message. The present disclosure save time and improve the efficiency of random access.

Systems and methods are provided for leveraging uplink (U)L scheduling information obtained by way of Quality of Service (QoS) Null/QoS Data frames and Media Access Control (MAC) headers transmitted by any station (STA). This UL scheduling information can be read by any access point (AP) in an extended service set (ESS), and used to improve network performance. For example, an AP may use such UL scheduling information (from STAs associated to co-channel APs in the same ESS) to minimize the latency for UL latency-sensitive traffic in that ESS. Additionally, an AP may use such UL scheduling information to minimize contention amongst STAs connected to different APs on the same channel in the same ESS, thereby improving system capacity.

Provided is a buffer status reporting method, comprising: for any radio bearer with duplication function configured or activated on a link, determining that different logic channels of the radio bearer belong to different logic channel groups; and when a buffer status reporting condition is satisfied, performing a buffer status reporting procedure based on the buffer status of the different logic channel groups.

A method and apparatus are disclosed for configuring at least one set of beta offset values, and for each of the at least one set of beta offset values, at least one subset of beta offset values being defined for information corresponding to Uplink Control Information, UCI, and being associated with at least one service type. A method and apparatus are disclosed for obtaining a configuration of at least one set of beta offset values, for each of the at least one set of beta offset values, the configuration being associated with at least one subset of beta offset values, the at least one subset of beta offset values being defined for information corresponding to UCI and being associated with at least one service type.

Apparatuses, methods, and systems are disclosed for transmitting and/or receiving an indication for a transmission scheme. One method includes determining a transmission scheme for transmitting a first channel. The method includes transmitting an indication of the transmission scheme to a base unit. The indication is based on the transmission scheme.

A method of wireless communication includes selecting, by a user equipment (UE), a first codepoint from a codebook based on control information to be transmitted to a base station. The codebook is associated with non-coherent transmissions from the UE to the base station. The method further includes generating, based on the first codepoint and a scrambling sequence that is associated with the UE, a second codepoint representing the control information. The method further includes transmitting the second codepoint by the UE to the base station.

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

Embodiments of the present invention provide an uplink control information sending method, an uplink control information receiving method, an apparatus, and a system. The method includes: receiving, by a terminal device, channel indication information from an access network device on a physical control channel; determining the channel resource set that is of N channel resource sets and that matches a type or a size of the UCI as a first channel resource set; determining a channel resource that is in the first channel resource set and that is indicated by the channel indication information; and sending uplink control information UCI to the access network device on the channel resource. A quantity of bits that need to be added to the channel indication information in the embodiments of the present invention is less than that in the prior art.

A wireless device transmits, one or more radio resource control (RRC) messages indicating assistance information for a sidelink operation. The assistance information indicates: an identifier indicating a logical channel associated with a sidelink traffic; and one or more periodicities associated with the logical channel. In response to the assistance information, one or more second RRC messages indicating one or more configured grant configurations determined based on the one or more of periodicities of the logical channel is received. The wireless device triggers, a transmission of a buffer status report in response to sidelink data of the logical channel becoming available. A scheduling request (SR) is transmitted. In response to the SR: the transmission of the buffer status report is cancelled; and one or more activation commands indicating activation of the one or more configured grant configurations is received.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure relates to mobile communication technology, and in particular, to a method for uplink transmission and apparatus thereof.
