Description

Method and device used in user equipment and base station for wireless communication
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a communication method and apparatus supporting data transmission over an Unlicensed Spectrum (Unlicensed Spectrum).
Background
In a conventional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, data transmission can only occur on a licensed spectrum, however, with a drastic increase in traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communication over unlicensed spectrum in Release 13 and Release 14 was introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with other Access technologies over unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) of LTE to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources.
UpLink transmission in a conventional LTE system is often based on Grant (Grant) of a base station, and in order to avoid reduction of resource utilization rate and time delay caused by frequent LBT, Release 15 introduces Autonomous UpLink (AUL) transmission on an unlicensed spectrum. In the AUL, a UE (User Equipment) may autonomously perform uplink transmission in an air interface resource pre-configured by a base station. Currently, 5G NR (New Radio Access Technology) is under discussion regarding Access technologies for unlicensed spectrum, and unlicensed uplink transmissions on unlicensed spectrum need to be reconsidered.
Disclosure of Invention
The inventor finds, through research, how to improve the channel access opportunity in the uplink transmission on the unlicensed spectrum of the NR system, and more effectively realizes the sharing of the unlicensed spectrum resources by multiple transmitting nodes is a key problem to be solved.
In view of the above, the present application discloses a solution. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
The application discloses a method in user equipment for wireless communication, which is characterized by comprising the following steps:
-receiving K0 first signaling, the K0 first signaling being used for determining K time-frequency resource blocks;
-transmitting a first radio signal in a target set of time-frequency resources;
wherein, the frequency domain resources respectively occupied by any two time frequency resource blocks in the K time frequency resource blocks are orthogonal; the target time frequency resource set comprises time frequency resources occupied by the first wireless signals; the initial sending time of the first wireless signal belongs to a target initial time set, and the relation between the target time-frequency resource set and the K time-frequency resource blocks is used for determining the target initial time set; the target set of start times is a first set of start times or a second set of start times, the first set of start times including a positive integer of start times, the second set of start times including a positive integer of start times, the earliest start time in the second set of start times being earlier than the earliest start time in the first set of start times; the K0 is a positive integer, and the K is a positive integer.
As an embodiment, the problem to be solved by the present application is: to improve resource utilization, multiple UEs may share the same unlicensed spectrum resources. In order to reduce the large inter-user interference caused by the fact that a plurality of UEs seize channels simultaneously, how a base station allocates time-frequency resources to the UEs or starts sending time is a key problem to be solved.
As an embodiment, the problem to be solved by the present application is: to improve resource utilization, a UE that is not Granted uplink transmission and a UE that is based on Granted (Granted) uplink transmission may share the same unlicensed spectrum resource. Grant-based uplink transmission is generally preferred over grant-less uplink transmission on the same time-frequency resources. Therefore, how to design the grant-free uplink transmission to avoid the situation that the uplink transmission cannot be sent based on the grant because the channel is occupied is a key problem to be solved.
As an embodiment, the problem to be solved by the present application is: in order to improve the channel access opportunity and more effectively realize the sharing of the unlicensed spectrum resources by multiple transmitting nodes, the channel access opportunity can be improved by selecting narrowband LBT (i.e. bandwidth less than CC or BWP) when the bandwidth greater than the regulatory requirement (e.g. 20MHz at 5GHz carrier frequency and 1GHz at 60GHz carrier frequency) is met. When the base station employs narrowband LBT, the frequency domain resources in a CC or BWP that can be used for downlink transmission and uplink transmission based on grant may be dynamically changed, and how to design uplink transmission without grant to reduce the problem that uplink transmission based on grant cannot be sent due to occupying the channel is a key issue to be solved.
As an embodiment, the essence of the above method is that K time frequency resource blocks belong to one COT acquired by the base station or respectively belong to K COTs acquired by the base station, the target time frequency resource set is a time frequency resource allocated to the grant-free uplink transmission, the first wireless signal is the grant-free uplink transmission, and a relationship between the time frequency resource allocated to the grant-free uplink transmission and the one COT or the K COTs acquired by the base station is used to determine the initial transmission time set of the grant-free uplink transmission. The method has the advantages that the initial sending time of the uplink transmission without being granted takes the possible uplink transmission based on the grant into consideration, and the opportunity that the uplink transmission based on the grant preferentially occupies the channel can be improved.
According to one aspect of the application, the above method is characterized in that if the time-frequency resources occupied by the target time-frequency resource set and the time-frequency resources occupied by the K time-frequency resource blocks are partially overlapped, and the target time-frequency resource set comprises time-frequency resources orthogonal to the time-frequency resources occupied by the K time-frequency resource blocks, the target starting time set is the first starting time set.
As an embodiment, the essence of the above method is that if only part of the time frequency resources allocated to the grant-free uplink transmission belong to one COT or K COTs obtained by the base station, the starting transmission time set of the grant-free uplink transmission is the first starting time set (i.e. a set including later starting times). The method has the advantages that the initial sending time of the uplink transmission without the grant considers the possible uplink transmission based on the grant, and the opportunity that the uplink transmission based on the grant preferentially occupies the channel can be improved.
According to one aspect of the application, the above method is characterized in that if the time-frequency resources occupied by the target time-frequency resource set belong to the time-frequency resources occupied by the K time-frequency resource blocks, the target starting time set is the first starting time set; and if the time frequency resources occupied by the target time frequency resource set and the time frequency resources occupied by the K time frequency resource blocks are orthogonal, the target starting time set is the second starting time set.
As an embodiment, the essence of the above method is that if the time-frequency resources allocated to the grantless uplink transmission all belong to one COT or K COTs obtained by the base station, the starting transmission time set of the grantless uplink transmission is the first starting time set (i.e. a set including the later starting time); if the time-frequency resources allocated to the grantless uplink transmission are all out of one COT or K COTs obtained by the base station, the starting transmission time set of the grantless uplink transmission is the second starting time set (i.e. a set including earlier starting time). The method has the advantages that the initial sending time of the uplink transmission without the grant considers the possible uplink transmission based on the grant, and the opportunity that the uplink transmission based on the grant preferentially occupies the channel can be improved.

Example 3
Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3.
Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (gNB or eNB) in 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 PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.
