Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communications, and more particularly, to a method for determining non-contention random access resources, a network device and a terminal device. BACKGROUND

[0002] With the pursuit of rate, delay, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standard organization began to develop the 5-Generation (5G) mobile communication technology. In the early deployment of New Radio (NR), it is difficult to obtain complete NR coverage, so the typical network coverage is a wide-area Long Term Evolution (LTE) coverage and an NR island coverage mode. Moreover, due to a large number of LTE deployments below 6 gigahertz (GHz), there are few 6GHz below spectrum available for 5G. Therefore, NR must study the application of spectrum above 6GHz, and the coverage of high frequency bands is limited and the signal decays quickly.

[0003] In the prior art, due to the limited uplink power of the terminal device and the high frequency of the NR spectrum (high frequency, high propagation loss), the uplink coverage is limited. In order to improve the uplink coverage, the LTE spectrum (relatively low frequency) is used as an auxiliary uplink spectrum (i.e., there is an auxiliary uplink carrier), which can improve the uplink coverage.

[0004] However, in the scenario where the terminal device does not have an auxiliary uplink (SUL), the non-contention random access resources are configured to the terminal device in the form of Radio Resource Control (RRC) or Physical Downlink Control Channel (PDCCH) order, at this time there is only one uplink carrier, so the terminal device is clear about the configuration of the non-contention random access resources, and can correctly select the non-contention random access resources to initiate the random access process.

[0005] However, in the scenario where the terminal device has an auxiliary uplink (SUL), for example, in the scenario where the terminal device has at least two uplink (UL) carriers, using the existing configuration method, the terminal device does not know which uplink carrier resource to use.

[0066] Figure 1 is an example of an application scenario of an embodiment of the present application.

[0067] As shown in Figure 1 , the terminal device can have one downlink carrier and two uplink carriers (as shown in Figure 1 , the first uplink carrier and the second uplink carrier). Specifically, the first uplink carrier and the downlink carrier can be carriers on an NR high frequency band, and the second uplink carrier can be a carrier on an LTE low frequency band. It should be understood that Figure 1 the terminal device having two uplink carriers as shown is only an exemplary description, and embodiments of the present application are not limited specifically. For example, the terminal device can also support three uplink carriers, and the like.

[0068] It should be appreciated that the motivation for introducing the second uplink carrier is to improve the uplink coverage of NR high frequency bands.

[0069] Specifically, because the uplink power of the terminal device is limited, and the frequency of the spectrum (high frequency, high propagation loss) of NR is relatively high, the uplink coverage of NR is limited. In order to improve the uplink coverage, a method for transmitting data is proposed in the embodiments of the present application. By using the LTE spectrum (relatively low frequency) as an auxiliary uplink carrier, the uplink coverage effect can be improved.

[0070] For example, the combination of the first uplink carrier and the second uplink carrier can be similar to the carrier aggregation (CA) in LTE, except that there is no paired downlink. That is, from the perspective of band combination, the second uplink carrier is a cell with only uplink and no paired downlink, but its uplink is controlled by a certain downlink carrier, that is, when the second uplink carrier is configured, the second uplink carrier is an auxiliary service cell (SCell) without downlink, and the control of the second uplink carrier depends on the primary service cell (PCell).

[0071] It should be appreciated that the embodiments of the present application can be applied to any communication system including multiple uplinks. For example, the first communication system and the second communication system can be various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc.

[0072] In addition, the present application describes various embodiments in combination with network devices (the first network device to the fourth network device) and terminal devices.

[0073] The network device can refer to any entity on the network side for transmitting or receiving signals. For example, it can be a user equipment of machine type communication (MTC), a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, a base station device in a 5G network, etc.

[0074] The terminal device can be any terminal device. Specifically, the terminal device can communicate with one or more core networks (Core Network, RAN) through a radio access network (Radio Access Network, RAN), also known as an access terminal, user equipment (User Equipment, UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it can be a cellular phone, a cordless phone, 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), 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 terminal device in a 5G network, etc.

[0075] In combination with the non-contention random access process, it can be found that in the non-assisted uplink (SUL) scenario, the non-contention random access resource is configured to the UE in the form of RRC or PDCCH order. At this time, there is only one uplink carrier, so the UE is clear about the configuration of the non-contention random access resource, and can correctly select the non-contention random access resource to initiate the random access process. However, in the SUL scenario, there are at least two uplink (UL) carriers, so the terminal device does not know which uplink carrier resource to use according to the existing configuration mode.

[0076] Therefore, in the embodiment of the present application, a method for determining non-contention random access resources is proposed. When there are at least two uplink (UL) carriers in the terminal device, the non-contention random access resources can be determined.

[0077] The following will be described in combination with Figure 2 The contention random access of the embodiment of the present application is described.

[0078] Figure 2 The method for non-contention random access of the embodiment of the present application is a schematic flowchart.

[0079] 210, the network device generates indication information

[0080] 220, the network device sends the indication information to the terminal device

[0081] 230, the terminal device performs random access according to the indication information

[0082] Specifically, the network device generates indication information, the indication information indicating a first resource on a first uplink carrier and / or a second resource on a second uplink carrier for non-contention random access of the terminal device, the frequency point of the first uplink carrier and the frequency point of the second uplink carrier being different; the network device sends the indication information to the terminal device. So that the terminal device performs random access according to the received indication information.

[0083] The specific content of the indication information is exemplarily described as follows:

[0084] In an embodiment, the indication information can include the carrier resource selected by the network device for the terminal device. In other words, the network device directly indicates the carrier resource selected by the network device to the terminal device.

[0085] For example, the indication information can include identification information of the first uplink carrier and information for indicating the first resource.

[0086] For another example, the indication information can include identification information of the second uplink carrier and information for indicating the second resource.

[0087] In the embodiment of the application, since the carrier resource is selected by the network device. Optionally, before the network device generates the indication information, the network device receives a channel quality measurement report sent by the terminal device; then, the network device determines the uplink carrier for non-contention random access of the terminal device according to the channel quality measurement report; and generates the indication information according to the uplink carrier for non-contention random access of the terminal device.

[0088] It should be understood that the channel quality measurement report includes but is not limited to:

[0089] Reference Signal Receiving Power (RSRP) and / or Reference Signal Receiving Quality (RSRQ) of the cell corresponding to the first uplink carrier and RSRP and / or RSRQ of the cell corresponding to the second uplink carrier.

[0090] Specifically, the network device configures a set of non-contention random access resources for the terminal device, and indicates that the set of non-contention random access resources belongs to which UL carrier. Specifically, the network device can select the UL carrier for the terminal device to initiate non-contention random access resources according to the measurement result report reported by the terminal device. For example, in a handover scenario, the network device knows the signal quality, at this time, the terminal device currently located in a cell needs to send the measurement result (e.g., RSRP / RSRQ) of the terminal device to the target cell to the target cell for the target cell to select the UL carrier. In the embodiment of the application, when the network device configures the dedicated random access resources for the terminal device, the measurement result can be referred to for the terminal device to configure the dedicated random access resources.

[0091] In another embodiment, the indication information can include resources on each uplink carrier. In other words, the network device directly indicates to the terminal device the resources of all uplink carriers available to the terminal device, and the terminal device finally selects the resources for non-contention random access.

[0092] For example, the indication information can include: identification information of the first uplink carrier, identification information of the second uplink carrier, information for indicating the first resource, and information for indicating the second resource.

[0093] Specifically, each set of non-contention random access resources configured by the network device for the terminal device is provided with a corresponding UL carrier number, indicating that the non-contention random access resources belong to which UL carrier, so that the terminal device can know the correspondence between the non-contention random access resources and the UL carrier. For example, the terminal device can select non-contention random access resources according to the RSRP measurement result and initiate a random access process. For example, when the RSRP measurement result is greater than a certain threshold, the UE can select the non-contention random access resources corresponding to the NR UL. Otherwise, the UE can only select the non-contention random access resources corresponding to the SUL.

[0094] Further, the indication information can also include:

[0095] The priority information corresponding to the first resource and / or the priority information corresponding to the second resource.

[0096] Therefore, when the network device configures two sets of non-contention random access resources, each set of non-contention random access resources is configured with a priority indication, indicating that the terminal device preferentially uses a set of non-contention random access resources when the signal condition allows (e.g., RSRP is greater than a certain threshold).

[0097] Optionally, before the network device generates the indication information, the network device determines the priority information corresponding to the first resource and / or the priority information corresponding to the second resource according to at least one of the following information:

[0098] The processing load of the first uplink carrier, the processing load of the second uplink carrier, the load of the Physical Random Access Channel (PRACH) resources of the first uplink carrier, and the load of the PRACH resources of the second uplink carrier.

[0099] In other words, the priority information corresponding to the first resource and / or the priority information corresponding to the second resource in the indication information can be set based on the processing load of the two uplink carriers and the load of the PRACH resources of the two carriers.

[0100] It should be understood that, in this embodiment of the invention, the resources used by the terminal device for non-contention random access include, but are not limited to: identification information of the preamble and PRACH resources for sending the preamble.

[0101] The following is an example illustrating the transmission method of indication information in an embodiment of the present invention:

[0102] In one embodiment, the network device sends Radio Resource Control (RRC) signaling to the terminal device, and the RRC signaling includes the indication information. That is, the indication information is carried in the RRC signaling and sent to the terminal device.

[0103] In another embodiment, the network device sends a Physical Downlink Control Channel (PDCCH) order to the terminal device, and the PDCCH order includes the indication information. That is, the indication information is carried in the PDCCH order and sent to the terminal device.
