Embodiment 1

[0102] Embodiment 1 illustrates the flowchart of M1 wireless signals; as attached figure 1 shown.

[0103]In Embodiment 1, the user equipment in this application sends M1 wireless signals respectively in M1 time windows among the M time windows. Wherein, the M1 wireless signals all carry the first bit block, and the user equipment only sends the wireless signal carrying the first bit block in the M time windows in the M time windows; The transmission powers of the M1 wireless signals are all the first power, and the first power is equal to the first reference power or the first power threshold; the first power and the earliest time window among the M1 time windows are in the The positions in the M time windows are related; the M is a positive integer greater than 1, and the M1 is a positive integer not greater than the M.

[0104] As an embodiment, any two wireless signals among the M1 wireless signals occupy the same frequency resource.

[0105] As an embodiment, any two w...

Embodiment 2

[0128] Embodiment 2 illustrates the schematic diagram of network architecture, as attached figure 2 shown.

[0129] attached figure 2 The network architecture 200 of LTE (Long-Term Evolution, long-term evolution), LTE-A (Long-Term Evolution Advanced, enhanced long-term evolution) and a future 5G system is described. The network architecture 200 of the LTE, LTE-A or 5G system may be referred to as an EPS (Evolved Packet System, evolved packet system) 200 . EPS 200 may include one or more UE (User Equipment, User Equipment) 201, E-UTRAN-NR (Evolved UMTS Terrestrial Radio Access Network-New Radio) 202, 5G-CN (5G-CoreNetwork, 5G core network) / EPC (Evolved Packet Core, Evolved Packet Core) 210 , HSS (Home Subscriber Server, Home Subscriber Server) 220 and Internet service 230 . Among them, UMTS corresponds to Universal Mobile Telecommunications System (Universal Mobile Telecommunications System). EPS 200 may be interconnected with other access networks, but these entities / in...

Embodiment 3

[0135] Embodiment 3 illustrates a schematic diagram of an embodiment of the wireless protocol architecture of the user plane and the control plane, as shown in the attached image 3 shown.

[0136] attached image 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, with image 3 The radio protocol architecture for UE and gNB is shown with three layers: Layer 1, Layer 2 and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. The L1 layer will be referred to herein as PHY 301 . Layer 2 (L2 Layer) 305 is above PHY 301 and is responsible for the link between UE and gNB through PHY 301 . In the user plane, the L2 layer 305 includes MAC (Medium Access Control, Media Access Control) sublayer 302, RLC (Radio Link Control, Radio Link Layer Control Protocol) sublayer 303 and PDCP (Packet Data Convergence Protocol, packet data convergence protoc...

Abstract

The invention discloses a method and device in user equipment and a base station used for wireless communication, being characterized in that the user equipment respectively sends M1 wireless signalsin M1 time windows in the M time windows; the M1 wireless signals all carry a first bit block, and the user equipment only sends the wireless signals carrying the first bit block in the M1 time windows in the M time windows; the sending power of the M1 wireless signals is first power, and the first power is equal to first reference power or a first power threshold; and the first power is related to the position of the earliest time window in the M1 time windows in the M time windows. In uplink transmission based on configuration granting, when the actual repeated sending frequency is smaller than the pre-configured repeated frequency, the method can improve the performance of uplink transmission.

Description

technical field [0001] The present application relates to a method and a device in a wireless communication system, in particular to a method and a device in a wireless communication system supporting uplink transmission based on configured grant. Background technique [0002] In the traditional 3GPP (3rd Generation Partner Project, third-generation partnership project) LTE (Long-term Evolution, long-term evolution) system, the uplink transmission of the UE (User Equipment, user equipment) side often depends on the dynamic grant (dynamic grant) of the base station. ). In the 5G NR (New Radio Access Technology, new radio access technology) system, the UE can perform uplink transmission based on a configured grant in the air interface resources pre-configured by the base station, so as to reduce the overhead of air interface signaling and improve The spectral efficiency of the system. In the uplink transmission based on the configuration grant, the base station configures a ...
