Description

Wireless communication method, terminal equipment and network equipment

Technical Field

The embodiments of the present application relate to the field of communications, and in particular, to a wireless communication method, a terminal device, and a network device.

Background

In a New Radio (NR) system, a Secondary Cell (SCell) may be configured through Radio Resource Control (RRC) dedicated signaling, where an initial configuration state is a deactivated state, and data transmission and reception cannot be performed in the deactivated state. Then, the SCell is activated by a Media Access Control Element (MAC CE) to perform data transceiving. This results in a large delay for SCell activation, which in turn reduces Carrier Aggregation (CA) usage and efficiency of radio resources, especially in small cell deployment scenarios. In dense small cell deployment scenarios, the signaling load of each SCell is also large, especially if each SCell needs to be configured separately. Therefore, how to reduce the activation delay of the SCell is an urgent problem to be solved.

The embodiments of the present application are described in conjunction with a terminal device and a network device, where: a terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment, etc. The terminal device may be a Station (ST) in a WLAN, and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, and a next generation communication system, for example, a terminal device in an NR Network or a terminal device in a future evolved Public Land Mobile Network (PLMN) Network, and the like.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

The network device may be a device for communicating with a mobile device, and The network device may be an Access Point (AP) in a WLAN, a Base Station (BTS) in GSM or CDMA, a Base Station (NodeB, NB) in WCDMA, an evolved Node B (eNB, eNodeB) in LTE, a relay Station or an Access Point, or a fifth Generation mobile communication (5 th Generation, 5G) Base Station or NR Base Station (gNB) in an on-vehicle device, a wearable device, and an NR network, or a network device in a PLMN network that is evolved in The future, and The like.

In this embodiment of the present application, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

The SCell is configured through RRC dedicated signaling, and the initially configured state is a deactivated state in which data transmission and reception cannot be performed. And then the SCell is activated through the MAC CE so as to transmit and receive data. This architecture is not an optimal architecture from the SCell configuration and activation latency point of view. This delay, in turn, reduces the efficiency of CA usage and radio resources, especially in small cell deployment scenarios. In dense small cell deployment scenarios, the signaling load of each SCell is also large, especially if each SCell needs to be configured separately. Therefore, the current CA architecture introduces extra delay, limits the use of CA, and reduces the gain of CA load sharing.

The states of the SCell are divided into an active state and an inactive state, and a new cell state, i.e., a dormant state (dormant state), is defined for fast cell recovery. In the dormant state, the terminal device measures and reports a Channel Quality Indicator (CQI) and/or a Radio Resource Management (RRM) measurement, but does not decode a Physical Downlink Control Channel (PDCCH). Meanwhile, a MAC CE is newly defined to control the transition between the active state and the dormant state, and the state of the SCell may be configured as the active state or the dormant state in RRC signaling, and is default to the deactivated state.

To support the radio remote scenario, an SCell and a Primary Cell (PCell) may not be located at the same site, for example, as shown in fig. 2, the SCell and the PCell are not located at the same site. That is, for the UE, the receiving radio frequency of the base station side is not in the same geographical location for the two cells (SCell and PCell), so the TA is also different for the UE. Therefore, the concept of multiple TAs is introduced into LTE R11, that is, multiple cells may share cells of the same TA to form a TAG group, and the UE needs to initiate a random access procedure in the cell to acquire the TA of the TAG group.

For a cell of a TAG group, a process from configuration to activation for transmitting uplink and downlink data is shown in fig. 3 in the prior art, and specifically, the following steps may be included:

step 1, the gNB sends RRC signaling to the UE to add a secondary cell (SCell addition), for example, SCell A is configured in a TAG group;

step 2, the gNB activates the Downlink (DL) of the SCell A through MAC CE signaling;

step 3, the gNB sends a PDCCH order to the UE so that the UE triggers a random access process;

and step 4, the gNB sends a random access response to the UE to activate an Uplink (UL) of the SCell A, and the SCell A can only receive and transmit data at the moment.

However, for the TAG scenario, the cell activation delay in the STAG is too long, which reduces the cell throughput and UE throughput, and affects the UE performance and network performance. In order to quickly activate the uplink and downlink of the secondary cell and improve the throughput of the cell, it is necessary to reduce the cell activation delay.

Based on the above problem, the present application provides a scheme for rapidly activating an SCell, which can rapidly activate an uplink and a downlink of a secondary cell.

The scheme of the present application for fast activation of SCell designed to address the above technical problems is described in detail below.

s230, the terminal device determines the uplink state and/or the downlink state of each of the N secondary cells according to the first configuration information.

Optionally, after the terminal device enters the RRC connected state, the network device configures the first configuration information for the terminal device. For example, after the terminal device enters the RRC connected state, the network device configures a secondary cell (SCell) of the CA, and at the same time, performs group configuration on the SCell according to TAG. That is, in the embodiment of the present application, the terminal device is in the RRC connected state.

Of course, in the first configuration information, the status information of each of the N secondary cells is optionally configured, that is, the first configuration information may not include the status information of each of the N secondary cells.

It should be appreciated that in a secondary cell in a dormant state, the terminal device measures and reports CQI and/or RRM measurements, but does not decode the PDCCH.

Optionally, in this embodiment of the application, after S220, the terminal device receives first indication information sent by the network device, where the first indication information is used to indicate status information of each secondary cell in the N secondary cells. That is to say, if the first configuration information does not configure the status information of each of the N secondary cells, the network device may also indicate in an individual indication manner, so as to ensure that the terminal device obtains the status information of each of the N secondary cells. Further, the terminal device determines the uplink state and/or the downlink state of each of the N secondary cells according to the first configuration information and the first indication information.

the N secondary cells include a first secondary cell, and the first secondary cell does not belong to the STAG, the first secondary cell uses the first primary cell or the TA of the first primary and secondary cell,

if the state of the first secondary cell is an activated state, the terminal device determines that the downlink of the first secondary cell is in the activated state, and the terminal device determines the uplink state of the first secondary cell according to the uplink state of the first primary cell or the first primary and secondary cell; or

It should be noted that the terminal device may specifically determine the uplink state of the first secondary cell by:

If the uplink of the first primary cell or the first primary and secondary cell is in the deactivated state, the terminal device determines that the uplink of the first secondary cell is also in the deactivated state.

the terminal equipment triggers a random access process to be initiated on the second auxiliary cell, and acquires a first TA, wherein the first TA is shared by all auxiliary cells belonging to the first STAG;

the terminal device applies the first TA to all secondary cells in the first STAG, and then the uplink of all activated secondary cells in the first STAG is in an activated state.

It should be noted that the terminal device may specifically trigger the initiation of the random access procedure on the second secondary cell and acquire the first TA in the following manner:

the RRC layer of the terminal equipment sends the random access resource to the MAC layer of the terminal equipment;

and the MAC layer of the terminal equipment triggers a random access process to be initiated on the second auxiliary cell and acquires the first TA.

Correspondingly, after the MAC layer of the terminal device triggers the initiation of the random access procedure on the second secondary cell, the network device feeds back the first TA to the terminal device in a random access response.

Therefore, in the embodiment of the present application, in an STAG scenario, a cell in the STAG configures a state of an SCell in an RRC signaling, so as to determine an uplink state and/or a downlink state of the SCell, and/or a TAG group acquires non-contention random access resource configuration information of a TA, so as to determine, based on the TA, that the uplink state of the SCell that is in activation is an activation state, reduce an activation delay of the SCell, improve throughput and system performance, and improve user experience.
