The present application relates to a method and apparatus for uplink data transmission or reception. One embodiment of the subject application provides a method for uplink data transmission performed by a User Equipment (UE), comprising: receiving, from a base station (BS), a first signalling indicating a first channel access priority class value, wherein the first channel access priority class value is used by the BS for initiating a channel occupancy; receiving, from the BS, a second signalling scheduling a Physical Uplink Shared Channel (PUSCH) for transmitting uplink data; performing a channel access procedure; and transmitting, to the BS, the uplink data on the PUSCH in response to the channel access procedure being successful.

Network prioritization is contemplated. The network prioritization may relate to prioritizing consumption of network services as a function of user priority. The user priority may be associated with the devices desiring consumption of network services in order to ensure higher priority users are granted network resources over lower priority users.

The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. The present disclosure discloses a method and device for transmitting uplink data.

A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N−a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N−a), which are not currently allocated, is allocated.

Embodiments of the present invention disclose a signaling processing method. The method includes: in a downlink subframe set, generating a downlink assignment index (DAI) respectively for a downlink subframe that has a physical downlink control channel (PDCCH) to be sent, where a value of the DAI is generated according to a preset rule and a sequence of carrier first and then subframe; and sending the PDCCH to the user equipment, where the PDCCH carries the DAI. According to the embodiments of the present invention, a transmission delay is shortened and transmission efficiency is improved.

The disclosed embodiments provide for management of a Wi-Fi network in the presence of a high priority receiver. When a high priory receiver is identified, a portion of the Wi-Fi network that could potentially interfere with the high priority receiver is identified and steps are taken to reduce the probability of such interference. For example, some wireless transmitters may be switched to alternate channels to reduce the probability of interference. By sharing information relating to high priority receivers across a plurality of wireless transmitters, the disclosed embodiments provide for more efficient operation in the presence of high priority receivers when compared to methods that independently detect a high priority receiver at each wireless transmitter.

A user equipment (UE) may transmit a configured-grant uplink control information (CG-UCI) to a base station during a channel occupancy time (COT) initiated by the UE in a shared spectrum, the CG-UCI comprising COT sharing information, the COT sharing information indicating, at least, an index value corresponding to a combination of: an indication of an offset to a beginning of a downlink transmission opportunity during the COT; an indication of a duration of the downlink transmission opportunity during the COT; and an indication of a channel access priority class (CAPC) value used by the UE to initiate the COT. The base station may transmit a downlink transmission to the UE within the downlink transmission opportunity and in accordance with the COT sharing information in the transmitted CG-UCI. Apparatuses are also disclosed.

A terminal includes a reception unit configured to receive control information including information for allocating a plurality of uplink transmissions, from a base station, a control unit configured to identify a parameter applied to the plurality of uplinks, based on the control information, and a transmission unit configured to transmit the plurality of uplinks to the base station by applying the identified parameter to the plurality of uplinks.

An access procedure processing method, an apparatus, and a communications device are provided. The method includes: performing matching between N pieces of to-be-transmitted transmission data and a first condition; and based on a matching result, executing a first access procedure or a second access procedure. M pieces of transmission data are transmitted in the first access procedure, the N pieces of the transmission data are not transmitted in the second access procedure, and the M pieces of the transmission data are data matching the first condition in the N pieces of the transmission data. M and N are positive integers, and M is less than or equal to N. The first condition is a restriction condition for the data transmitted during the access procedure. The first condition includes: first bearer information corresponding to the transmission data or a first transmission mode matching configuration information.

A UE receives control signaling that indicates that the UE is scheduled to transmit one or more uplink control channel messages on a first component carrier that overlap in a time domain with one or more uplink shared channel messages scheduled for transmission on a second component carrier. The UE resolves a first overlap of uplink control channels having a same priority level, if present, and resolves, after resolving the first overlap, a second overlap of an uplink control channel and at least one uplink shared channel having the same priority level, if present. The UE resolves two or more channels having a different priority level after resolving the first overlap and the second overlap. The UE transmits one or more uplink transmissions including at least one of the one or more uplink control channel messages and the one or more uplink shared channel messages.
