The terminal device may be a Station (ST) in a WLAN, may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA) device, a handheld device with wireless communication functionality, 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, such as a terminal device in an NR network or a terminal device in a future evolved public land mobile network (Public Land Mobile Network, PLMN) network, etc.

By way of example, and not limitation, in embodiments of the present application, the terminal device may also be a wearable device. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The 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 can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

The network device may be a device for communicating with the mobile device, the network device may be an Access Point (AP) in WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or an Access Point, or a vehicle device, a wearable device, and a network device in NR network or a base station (gNB) or a network device in future evolved PLMN network, etc.

In the embodiment of the present application, the network device provides services for a cell, and the 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 may belong to 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 transmitting power and are suitable for providing high-rate data transmission services.

The 5G NR system defines an NTN system deployment scenario including a satellite network. NTN typically provides communication services to terrestrial users by way of satellite communications. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into Low Earth Orbit (LEO) satellites, medium Earth Orbit (MEO) satellites, geosynchronous Orbit (Geostationary Earth Orbit, GEO) satellites, high elliptical Orbit (High Elliptical Orbit, HEO) satellites, and the like according to the Orbit heights.

For example, LEO satellites range in altitude from 500km to 1500km, with corresponding orbital periods of about 1.5 hours to 2 hours. The signal propagation delay for single hop communications between users is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal is not high.

For another example, the GEO satellite orbit altitude is 35786km and the period of rotation around the earth is 24 hours. The signal propagation delay for single hop communications between users is typically 250ms.

It should be noted that, NR has a two-stage retransmission mechanism: HARQ mechanisms of the medium access control (Media Access Control, MAC) layer and automatic request retransmission (Automatic Repeat reQuest, ARQ) mechanisms of the radio link control (Radio Link Control, RLC) layer. The retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and complemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission and the ARQ mechanism of the RLC layer can provide reliable data transmission.

HARQ uses Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-wait protocol, the transmitting end stops waiting for acknowledgement after transmitting a transport block (Transmission block, TB). Thus, the sender stops waiting for acknowledgements after each transmission, resulting in low user throughput. Thus, NR uses multiple parallel HARQ processes, and when one HARQ process is waiting for acknowledgement information, the transmitting end can continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity that incorporates a stop-and-wait protocol, allowing continuous transmission of data. HARQ includes uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission, and downlink HARQ is for downlink data transmission. The two are independent from each other.

Based on the provision of the NR protocol, the terminal has a respective HARQ entity for each serving cell. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. A maximum of 16 HARQ processes are supported per uplink and downlink carrier. The base station may indicate the maximum number of HARQ processes to the terminal through a radio resource control (Radio Resource Control, RRC) signaling semi-static configuration according to the network deployment scenario. If the network does not provide the corresponding configuration parameters, the downlink default HARQ process number is 8, and the maximum HARQ process number supported by each uplink carrier is always 16. Each HARQ process corresponds to a HARQ process Identification (ID). For the downlink, the BCCH uses a dedicated broadcast HARQ process. For uplink, HARQ ID 0 is used for message 3 (msg 3) transmission in the random process.

For a terminal which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB at the same time; for a terminal supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal simultaneously processes 1 TB.

HARQ is classified into synchronous and asynchronous types in the time domain and into non-adaptive and adaptive types in the frequency domain. The NR uplink and downlink use asynchronous adaptive HARQ mechanisms. Asynchronous HARQ, i.e. retransmission, may occur at any time, the time interval between the retransmission of the same TB and the last transmission being not fixed. The adaptive HARQ may change the frequency domain resources and modulation coding scheme (Modulation and Coding Scheme, MCS) used for the retransmission.

In order to better serve periodic traffic, the concept of pre-configured resources is introduced, downlink being called SPS resources and uplink being called CG resources.

For each SPS configuration, the network device configures a limited number of downlink HARQ processes for the SPS configuration, and the network device uses the downlink HARQ processes to perform downlink transmission on SPS resources in a polling manner.

For each CG configuration, the network device configures a limited number of HARQ process numbers for the network device, and the terminal device uses these uplink HARQ processes to perform uplink transmission on CG resources in a polling manner. Assuming that both the HARQ process number of the CG resource at time t0 and the HARQ process of the CG resource at time t1 are HARQ ID i, when the terminal device group at time t0 packs the MAC PDU1 with the MAC PDU1 after the MAC PDU1 is stored in the HARQ ID i, until time t1, since the HARQ process used at time t0 is the same as the HARQ process used at time t0, the MAC PDU1 will be emptied (flush), even though the MAC PDU1 has not been transmitted correctly. Thus, a configuration grant timer (configurable granttmer) for each (per) HARQ process is introduced. The configurable GrantTimer is maintained in the following manner:

If the terminal device performs uplink transmission on a resource scheduled by a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and an HARQ process used for the uplink transmission can be used for configuring authorized transmission, the terminal device starts or restarts a configurable grant timer corresponding to the HARQ process.

If the terminal equipment performs uplink transmission on the configuration authorized resource, the terminal equipment starts or restarts the configurable GrantTimer corresponding to the HARQ process.

If the terminal equipment receives CG resource activation of PDCCH indication Type (Type) 2, the terminal equipment stops running configurable GrantTimer.

The MAC PDU stored in a certain HARQ process cannot be emptied (flush) before the configurable grant timer corresponding to that HARQ process times out.

In order to ensure data transmission continuity without increasing the number of HARQ processes, a scheme of turning on/off HARQ is introduced, specifically:

1. the network device may configure whether to turn on the HARQ functionality.

2. If the HARQ function is off, the terminal device does not need to send HARQ feedback for the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) to the network device.

3. In case of closing the HARQ feedback, HARQ retransmission is still supported in order to guarantee data transmission reliability.

4. The configuration of the HARQ function on or off may be performed based on the terminal device or based on the HARQ process. For the manner of configuration based on the terminal device, that is, the HARQ functions configuring all HARQ processes of the terminal device are simultaneously in an on or off state. For the configuration mode based on the HARQ process, that is, for a plurality of HARQ processes of one UE, the HARQ function of one part of HARQ processes may be configured to be in an on state, and the HARQ function of another part of HARQ processes may be configured to be in an off state.

5. The effect on other processes in both cases of turning on HARQ and turning off HARQ needs to be studied separately.

In NTN, if it is to support the HARQ function on or off based on the HARQ configuration, the time required for waiting for retransmission scheduling is different for the HARQ process of the off HARQ function and the HARQ process of the on HARQ function, such as: for an HARQ process that turns on the HARQ function, its waiting Time for retransmission is at least 1 Round Trip Time (RTT); for the HARQ process with the HARQ function turned off, retransmission can be achieved by blind scheduling, so that the time waiting for retransmission is relatively short. If there are both HARQ processes for the on HARQ function and HARQ processes for the off HARQ function in the HARQ processes reserved for SPS/CG, the time required for them to complete the transmission of one TB (including the initial transmission and the retransmission) is not the same.

The mode of using each HARQ process for SPS/CG polling obviously does not consider the difference of the HARQ processes in two states, in this way, for the HARQ process of starting the HARQ function, in order to avoid data which is transmitted by using the HARQ process before the data transmission of the same HARQ process is emptied (flush) but is not yet available for retransmission, for downlink, the downlink transmission is not performed on SPS of the same HARQ process by a network implementation mode, so that sufficient time is reserved for retransmission of the front TB; for upstream this problem can be avoided by configuring a longer configuration grant timer (configurable grant timer). But this is done at the cost of causing great waste of resources.

The following describes in detail the SPS/CG resource polling using HARQ process scheme devised by the present application for the technical problems described above.

Fig. 2 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, as shown in fig. 2, the method 200 may include some or all of the following:

s210, the first device determines a mapping pattern between a periodic resource and a plurality of HARQ processes according to configuration information for configuring the periodic resource, wherein the configuration information comprises the plurality of HARQ processes reserved for the periodic resource, and at least comprises a first type HARQ process and/or a second type HARQ process;

S220, the first device uses the first type HARQ process once according to the mapping pattern, and repeatedly polls the second type HARQ process.

Alternatively, the method 200 is applied to NTN networks. Of course, the method 200 may also be applied to other networks, which is not limited in this application.

In the embodiment of the present application, the first device may be a terminal device or a network device.

Optionally, if the first device is a terminal device, the first device needs to acquire the configuration information before step S210. For example, the first device receives the configuration information from a network device.

Optionally, if the first device is a network device, the first device may send the configuration information to the terminal device before step S210.

Optionally, if the plurality of HARQ processes includes a first type HARQ process, the plurality of HARQ processes may include one or more HARQ processes of the first type HARQ process. Similarly, if the plurality of HARQ processes includes the second type HARQ process, the plurality of HARQ processes may include one or more HARQ processes of the second type HARQ process.

Note that, the plurality of HARQ processes may also include other types of HARQ processes, which is not limited in this application.

Optionally, in the embodiment of the present application, the first type of HARQ process is an HARQ process with an HARQ function in an on state, and the second type of HARQ process is an HARQ process with an HARQ function in an off state.

Optionally, in the embodiment of the present application, HARQ process IDs of some or all HARQ processes in the first type HARQ process are consecutive, or HARQ process IDs in the first type HARQ process are not consecutive.

It is assumed that 4 HARQ processes are reserved for the periodic resource in the configuration information, for example, where HARQ ID 0, HARQ ID 1 and HARQ ID 2 are HARQ processes of the first type, for example, where HARQ ID 0 and HARQ ID 3 are HARQ processes of the first type, for example, and for example, where HARQ ID 0, HARQ ID 1 and HARQ ID 3 are HARQ processes of the first type.

Optionally, in the embodiment of the present application, HARQ process IDs of some or all HARQ processes in the second type HARQ process are consecutive, or HARQ process IDs in the second type HARQ process are not consecutive.

It is assumed that 4 HARQ processes are reserved for the periodic resource in the configuration information, for example, where HARQ ID 1, HARQ ID 2 and HARQ ID 3 are HARQ processes of the second type, for example, where HARQ ID 0 and HARQ ID 3 are HARQ processes of the second type, for example, and for example, where HARQ ID 0, HARQ ID l and HARQ ID 3 are HARQ processes of the second type.

Optionally, the configuration information further comprises a period of the periodic resource and a pre-configured scheduling radio network temporary identity (Configured Scheduling Radio Network Temporary Identity, CS-RNTI).

Optionally, the configuration information is specifically configured to configure at least one bandwidth Part (BWP) for each serving cell of the terminal device, and to configure the periodic resource for Part or all of the at least one BWP.

Optionally, the configuration information is carried in radio resource control (Radio Resource Control, RRC) signaling.

Optionally, in the embodiment of the present application, the periodic resource is an SPS resource, and the HARQ process reserved for the periodic resource is a downlink HARQ process.

Optionally, if the periodic resource is an SPS resource, the first device is a network device.

Optionally, in the embodiment of the present application, the periodic resource is a CG resource, and the HARQ process reserved for the periodic resource is an uplink HARQ process.

Optionally, if the periodic resource is a CG resource, the first device is a terminal device.

Alternatively, the periodic resource may be some other periodic resource, which is not limited in this application.

Alternatively, in the embodiment of the present application, the step S220 may specifically be:

starting from a first periodic resource, the first device uses the first type of HARQ process in sequence and then repeatedly polls the second type of HARQ process.

For example, assuming that 4 HARQ processes are reserved for the periodic resource in the configuration information, where HARQ ID 0, HARQ ID 1, and HARQ ID 2 are the first type HARQ process and HARQ ID 3 is the second type HARQ process, the first device uses HARQ ID 0, HARQ ID 1, HARQ ID 2, HARQ ID 3, and HARQ ID 3 in order from the first periodic resource, i.e., repeatedly polls for 4 times of HARQ ID 3.

starting from a first periodic resource, the first device cross uses the first type of HARQ process and the second type of HARQ process.

For example, assuming that 4 HARQ processes are reserved for the periodic resource in the configuration information, where HARQ ID 0, HARQ ID 1 and HARQ ID 2 are the first type HARQ process and HARQ ID 3 is the second type HARQ process, starting from the first periodic resource, the first device uses HARQ ID 0, HARQ ID 3, HARQ ID 1, HARQ ID 3, HARQ ID 2, HARQ ID 3 in order, i.e. repeatedly polls 6 times HARQ ID 3.

Alternatively, in the embodiment of the present application, the number of repeated polls of the second type HARQ process may be controlled by a timer, or the number of repeated polls of the second type HARQ process may be controlled by a threshold.

Optionally, as example 1, the first device starts or restarts a first timer when the periodic resource-associated HARQ process 0, and stops polling the second type HARQ process when the first timer expires, wherein the first timer is used to limit a minimum time interval for the same HARQ process that has the HARQ function turned on to be used for the periodic resource transmission.

Optionally, the first periodic resource is a first resource when the first timer is in a closed state, or the first periodic resource is a first resource after the first timer expires.

Alternatively, in example 1, the initial state of the first timer is an off state.

Optionally, in example 1, the duration of the first timer is determined according to the following parameters:

RTT of signal transmission between terminal equipment and network equipment, maximum transmission times of MAC TB, and network scheduling delay.

For example, the duration of the first timer may be determined according to the following equation 1.

T=r×n+d formula 1

Wherein T is the duration of the first timer, R is RTT of signal transmission between the terminal equipment and the network equipment, N is the maximum transmission times of the MAC TB, and D is the network scheduling delay.

Optionally, in example 1, the first timer is configured by the configuration information, or the first timer is preconfigured or indicated by the network device.

Alternatively, as example 2, the first device stops polling the second type HARQ process if the number of repeated polls of the second type HARQ process is greater than or equal to a first threshold.

Optionally, in example 2, the first threshold is configured by the configuration information, or the first threshold is preconfigured or indicated by the network device.

Optionally, in an embodiment of the present application, the first device repeatedly uses the mapping pattern to transmit data on the periodic resource.

Therefore, in the embodiment of the present application, in the case that the first type HARQ process and/or the second type HARQ process are reserved for the periodic resource, the terminal device uses the first type HARQ process once according to the determined mapping pattern between the periodic resource and the HARQ process, and repeatedly polls the second type HARQ process. The HARQ process design of SPS resources and CG resources in the NTN system can be realized, the scheduling performance can be effectively ensured, and meanwhile, the SPS resources and/or CG resources can be more efficiently utilized for data transmission.

The wireless communication method 200 of the embodiment of the present application is described in detail below by way of specific embodiments.
