Embodiment 1

[0085] Embodiment 1 exemplifies a flow chart of first information, first signal, and first signaling according to an embodiment of the present application. figure 1 Indicated. With figure 1 In each box, each box represents a step, in particular, it is important to emphasize the order in which each block in the figure does not mean that the steps indicated between the steps are in time.

[0086] In Embodiment 1, the first node device in the present application receives the first information in step 101, the first information being used to determine the first length of length, the first length of length than 0; in step 102 The first signal is transmitted, and the time-frequency resource occupied by the first signal is used to indicate the first identification; in step 103, the first signal is monitored, the first identification being used for the Monitoring of the first signaling; the first signal includes X sub-signal, the X is a positive integer greater than 1, and the first symbol ...

Embodiment 2

[0298] Embodiment 2 illustrates a schematic diagram of a network architecture according to the present application, figure 2 Indicated. Attach figure 2 A map of the network architecture 200 of 5G NR, LTE (Long-Term Evolution, long evolution) and LTE-A (Long-Term Evolution Advanced, enhanced long-term evolution) system. 5G NR or LTE Network Architecture 200 can be referred to as 5GS (5G System) / EPS (Evolved Packet System, Evolution Packet System) 200 Some other suitable terms. 5GS / EPS 200 can include one or more UE (User Equipment, User Equipment) 201, NG-RAN (next-generation wireless access network) 202, 5GC (5G Core Network, 5G core network) / EPC (Evolved Packet Core, Evolution Group Core) 210, HSS (Home Subscriber Server, Home Sign User Server) / UDM (Unified Data Management) 220 and Internet Services 230.5GS / EPS can interconnect with other access networks, but for simple Demonstrate these entities / interfaces. As shown, 5GS / EPS provides package exchange services, howe...

Embodiment 3

[0312] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture according to a user plane and a control plane according to the present application. image 3 Indicated. image 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for user plane and control plane, image 3 The radio protocol architecture for the first node device (UE) and a second node device (satellite or aircraft in GNB, ENB or NTN) is shown in three layers: layer 1, layer 2 and layer 3. The layer 1 (L1 layer) is the lowest layer and performs various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. The layer 2 (L2 layer) 305 is above the PHY301 and is responsible for link between the PHY 301 in the first node device and the second node device. In the user plane, the L2 layer 305 includes MAC (Medium Access Control, Media Access Control) sub-layer 302, RLC (Radio Link Control, Radio Link Layer Contr...

Abstract

The invention discloses a method and an apparatus in a node for wireless communication. The method comprises the following steps: receiving first information by a node, wherein the first information is used for determining a first time length; sending a first signal, wherein a time-frequency resource occupied by the first signal is used for indicating a first identifier; and monitoring a first signaling in a first time window, wherein the first identifier is used for monitoring the first signaling. The first signal comprises X sub-signals, the X is a positive integer greater than 1, a first symbol set is used for generating any one sub-signal in the X sub-signals, and the X sub-signals are respectively X times of repeated transmission of the first symbol set; the X is used for determining a second time length; the sending cut-off moment of the first signal, the first time length and the second time length are used for determining the starting moment of the first time window; the first signal is used for random access. The power consumption can be reduced.

Description

Technical field [0001] The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly to a random access to a wireless communication. Background technique [0002] The application scenario of the future wireless communication system is increasingly diversified, and different application scenarios make different performance requirements. In order to meet the different performance requirements of various application scenarios, the new vacation technology is determined at the 3GPP (3RD Generation PartnerProject, the third-generation partner project) RAN (Radio Access Network, Wireless Access Network) # 72 plenary session (NR, NEW RADIO) (or 5G) conducts research, and NR is started to standardize NR through the Wi (Work Item, Work Project) of NR, New Radio, in 3GPP RAN # 75 plenary. [0003] In order to adapt to a variety of application scenarios and meet different needs, the research projects in NRP RAN (NON-TERRESTRI...
