The invention of the original application is named: method and device in wireless communication

Technical Field

The present invention relates to a transmission scheme in a wireless communication system, and more particularly, to a method and apparatus for uplink transmission.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on a New air interface technology (NR, New Radio) is decided in #72 global meetings of 3GPP (3rd Generation partnership project) RAN (Radio Access Network).

In an existing cellular wireless communication system (e.g., LTE, Long Term Evolution), uplink and Downlink data transmission is based on central scheduling, that is, radio resources and modulation and coding schemes occupied by Downlink transmission from each base station to User Equipment (UE) are allocated by the base station, radio resources and modulation and coding schemes occupied by uplink transmission from each user equipment to the base station are also allocated in advance by the base station, and the uplink and Downlink scheduling Information is carried in DCI (Downlink Control Information). Such uplink and downlink transmission modes in which resources are allocated by a center (base station) may be collectively referred to as Grant-based uplink and downlink transmission.

In next generation wireless cellular networks (such as 5G NR, further evolution of LTE, further evolution of NB-IoT (Narrow band internet of Things), supporting only grant-based data transmission cannot meet the increasingly diverse application requirements. Especially for uplink transmission, in a scenario with a high requirement on Low Latency or capacity, such as URLLC (Ultra Reliable Low Latency Communication), where the requirement on Latency is very strict, and an application scenario of mtc (massive Machine Type Communication) or NB-IoT or emtc (enhanced Machine Type Communication), where the requirement on system capacity is very high, the requirement on the scenario cannot be met due to the limitation of scheduling Latency and transmission initiation overhead based on the grant method. Thus, transmission in the uplink may be accomplished in a Grant-free manner as opposed to a Grant-based manner. The non-granted uplink transmission does not require the base station to dynamically allocate the radio resources and/or modulation and coding schemes occupied by the transmission before starting the uplink transmission, and thus the overhead required at the time of transmission and at the time of initiating the transmission can be reduced.

Disclosure of Invention

In cellular physical network systems (e.g., NB-IoT and eMTC), uplink and downlink data are typically transmitted repeatedly many times in order to enhance coverage performance. Meanwhile, due to the low requirement for cost, frequency offsets of oscillators (oscillators) adopted by NB-IoT User Equipment (UE) and eMTC User Equipment (UE) are relatively severe, which causes the user equipment to lose synchronization (desynchronization for short) or deteriorate synchronization accuracy during long-time transmission. The residual time offset and the residual frequency offset caused by the deterioration of the synchronization performance may cause a serious degradation of the transmission performance. In NB-IoT and eMTC systems, the problem caused by the step loss is particularly serious due to the use of a general crystal oscillator with long transmission time and low cost, and the half-duplex transmission mode adopted by the user equipment. Based on this, a time gap (ULgap) is introduced for long-time uplink transmission in NB-IoT and eMTC systems, that is, the user equipment may suspend uplink transmission after continuously transmitting uplink data for a certain time, and the user equipment may monitor downlink synchronization or reference signals, thereby ensuring synchronization of local oscillators.

The existing time slot designs are based on single signal or Channel (such as NPRACH (Narrow band physical Random Access Channel) or NPUSCH (Narrow band physical Shared Channel)) transmission, but in the process of non-grant based uplink transmission, a Preamble (Preamble) is generally used to attach to a data Channel (PUSCH or NPUSCH) for transmission, so as to achieve the purpose of simplifying signal detection. In this case, if the existing design of the time slot (UL gap) is used, it may happen that neither the preamble sequence nor the data channel satisfies the condition of inserting the time slot, but the transmission time of the preamble sequence and the data channel is long, so that the synchronization performance is degraded, and the transmission performance of the data channel is degraded.

The invention provides a solution to the problem of performance degradation caused by synchronization degradation in continuous long-time transmission in non-grant-based uplink transmission. The scheme designs an insertion method of a time gap (UL gap) based on the transmission time length of two signals transmitted in an uplink mode, and therefore the problem that the transmission performance is reduced due to the deterioration of the synchronization performance is solved. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE (User Equipment) of the present application may be applied to the base station, and vice versa.
