Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an information processing method, a terminal and a network device. Background Art

[0002] In the Long Term Evolution (LTE) system, terminals using Side Link (SL) communication work in broadcast (BC) or groupcast (GC) mode. When the network device is responsible for scheduling SL grant, it can send the carrier information and corresponding resource information available in SL to the transmitting terminal (Tx UE) through downlink control information (DCI), but the cross-carrier scheduling function is not supported in the LTE system.

[0240] 2. Direct communication

[0241] Direct communication refers to the way that adjacent terminals can transmit data over a short distance through SL or PC5. The wireless interface corresponding to the SL link is called the direct communication interface (also called SL interface or PC5 interface). Figure 2 shown.

[0242] On the direct link, the terminal can work in UC, BC, or GC. In UC, there is an SL radio resource control (RRC) connection between the Tx UE and the Rx UE for sending RRC layer messages. The terminal works in Mode 1 (Mode1) or Mode 2 (Mode2). In Mode 1, there is an RRC connection between the terminal and the network device (such as the base station). The base station is responsible for scheduling resources and sending them to the Tx UE, and the Tx UE further determines the resources used for the direct link; in Mode 2, the Tx UE is responsible for scheduling the resources used for the direct link.

[0243] In the LTE system, the transmitting terminal reports a list of carrier (or frequency) information and a list of Layer 2 Identifier (L2 ID) information corresponding to each carrier to the network device. When the network device is responsible for scheduling SL authorization, it can send the available carrier information and resource information on the SL to the Tx UE through DCI, and does not support cross-carrier scheduling. The receiving terminal (Rx UE) can receive the direct link control information (Sidelink Control Information, SCI) on all relevant carriers based on the carrier information list corresponding to the service identification information, and receive the physical direct link shared channel (Physical SideLink Shared Channel, PSSCH) related information according to the SCI to obtain data. The terminal can report a buffer status report (Buffer Status Report, BSR), which includes the L2 ID and the corresponding logical channel group identifier (Logical Channel Group Identifier, LCG ID) and data size (data size) information.

[0244] In the NR system, the SL terminal can report the L2 ID and the corresponding requested carrier information to the network device. For example, the Vehicle to Everything (V2X) layer of the SL terminal can send an L2 ID and the corresponding supported carrier set to the Access Stratum (AS), or send a Quality of Service (QoS) flow-related carrier information, and the AS layer determines the carrier information corresponding to the L2 ID. However, the carrier information currently reported by the terminal is for a single carrier and has nothing to do with CA.

[0245] In direct link communication, the working modes of mode 1 and CA are considered to be supported, that is, the network equipment (such as base station) schedules the carrier and corresponding resources of the SL link and works in a multi-carrier scenario. This requires the network equipment to allocate the available carriers on the SL and the corresponding SL resources on each carrier to the terminal. However, based on the prior art, the network equipment does not know the carrier information available for the SL interface, and therefore cannot allocate effective SL resources for SL data transmission.

[0246] The embodiments of the present application provide an information processing method, a terminal, and a network device to solve the problem that the prior art cannot guarantee the effective allocation of carriers and resources of SL in CA mode. The method and the terminal (or network device) are based on the same application concept. Since the principles of solving the problem by the method and the terminal (or network device) are similar, the implementation of the method and the terminal (or network device) can refer to each other, and the repeated parts will not be repeated.

[0247] like Figure 3 As shown, an embodiment of the present invention provides an information processing method, comprising the following steps:

[0248] Step 31: The terminal sends carrier information related to carrier aggregation of the first direct link to the network device.

[0249] Optionally, the carrier information related to the carrier aggregation of the first direct link reported by the terminal may indicate at least one of the following: a carrier that can be used by the terminal in the first direct link (for example, the carrier information may include a carrier identifier or a carrier set identifier, which is used to explicitly indicate the carrier that can be used by the terminal in the first direct link, etc.), and indication information for determining the carrier that can be used by the terminal in the first direct link (for example, one or more parameters associated with the carrier, which are used to implicitly indicate the carrier that can be used by the terminal in the first direct link, etc.).

[0250] Step 32: The terminal receives first indication information sent by the network device; wherein the first indication information is used to indicate a first carrier and / or wireless resources of the first carrier that the terminal can use in the first direct link, and the first carrier and / or the wireless resources of the first carrier are determined according to the carrier information.

[0251] Optionally, the carrier that the terminal can use in the first direct link, which is explicitly or implicitly indicated by the carrier information, may further support carrier aggregation. In this way, the carrier information reported by the terminal can be used by the network device to determine the first carrier and / or the radio resources of the first carrier that the terminal can use when the carrier of the first direct link is aggregated.

[0252] Optionally, the first indication information may indicate but is not limited to at least one of the following:

[0253] The first carrier that the terminal can use in the carrier aggregation of the first direct link (for example: the first indication information may include the carrier identifier or carrier set identifier of the first carrier, etc., used to explicitly indicate the carrier that the terminal can use in the carrier aggregation of the first direct link, etc.) and / or the wireless resources of the first carrier.

[0254] Indication information used to determine the carrier that the terminal can use in the carrier aggregation of the first direct link (for example: the first indication information may include one or more parameters associated with the first carrier, used to implicitly indicate the carrier that the terminal can use in the carrier aggregation of the first direct link, etc.) and / or the wireless resources of the first carrier.

[0255] The first indication information may also indicate the wireless resources of the first carrier in an explicit or implicit manner, but the embodiment of the present application is not limited thereto.

[0256] It should be noted here that the carrier information reported by the terminal explicitly or implicitly indicates the carrier that can be used for carrier aggregation in the first direct link determined by the terminal, and the first indication information explicitly or implicitly indicates the carrier that can be used for carrier aggregation in the first direct link determined by the network device based on the carrier information reported by the terminal. Furthermore, the terminal can select the carrier used for carrier aggregation from the first carrier indicated by the network device, or select the logical channel with the highest priority and the corresponding layer 2 identifier based on the wireless resources of the first carrier, and send the packaged Media Access Control Protocol Data Unit (MAC PDU).

[0257] In the above scheme, the terminal sends the carrier information related to the carrier aggregation of the first direct link to the network device, so as to effectively support the network device to determine the carrier and / or related resources that the terminal can use in the carrier aggregation of the first direct link, that is, to enhance the carrier information content reported by the terminal to the network device, to ensure that the network device can select a suitable carrier to execute the direct link carrier and / or related resource scheduling in Mode 1, and to avoid the network device allocating an invalid direct link carrier to the terminal, resulting in the terminal being unable to receive data due to monitoring the invalid direct link carrier, thereby solving the problem that the prior art cannot guarantee the effective allocation of carriers and resources of SL in CA mode.

[0258] Optionally, the carrier information includes at least one of the following:

[0259] The first carrier set; for example, the first carrier set may also be referred to as a carrier aggregation set (CA set), which may include at least one carrier that can be used by the terminal in the first direct link, and the carrier may optionally support CA.

[0260] Layer 2 identification information, and a first carrier set corresponding to the layer 2 identification information; for example, the terminal may report each L2 ID and a CA set corresponding to the L2 ID to the network device.

[0261] The first mapping relationship includes a mapping relationship between a service type and a first carrier set, and a mapping relationship between the service type and layer 2 identification information; for example: when the terminal reports the first mapping relationship, the network device side can determine the first carrier set corresponding to the L2 ID based on the first mapping relationship, that is, the first mapping relationship can implicitly indicate the first carrier set corresponding to the L2 ID, wherein the first carrier set includes at least one carrier that the terminal can use on the first direct link, and the carrier optionally supports CA.

[0262] The second mapping relationship includes a mapping relationship between a quality of service flow (QoS flow) and a first carrier set, and a mapping relationship between the quality of service flow and layer 2 identification information; for example: when the terminal reports the second mapping relationship, the network device side can determine the first carrier set corresponding to the L2 ID or QoS flow based on the second mapping relationship, that is, the second mapping relationship can implicitly indicate the first carrier set corresponding to the L2 ID, wherein the first carrier set includes at least one carrier that the terminal can use on the first direct link, and the carrier optionally supports CA.

[0263] The third mapping relationship includes a mapping relationship between a service type and a service quality flow, a mapping relationship between the service type and a first carrier set, and a mapping relationship between the service quality flow and layer 2 identification information; for example: when the terminal reports the third mapping relationship, the network device side can determine the first carrier set corresponding to the L2 ID or QoSflow based on the third mapping relationship, that is, the third mapping relationship can implicitly indicate the first carrier set corresponding to the L2 ID, wherein the first carrier set includes at least one carrier that the terminal can use on the first direct link, and the carrier optionally supports CA.

[0264] In this embodiment, the terminal can effectively support the network device to learn the carriers that the terminal can use in the carrier aggregation of the first direct link by reporting the carrier information in at least one of the above items, thereby being able to effectively determine the carriers and / or related resources that the terminal can use in the carrier aggregation of the first direct link. That is, the carrier information content reported by the terminal to the network device is enhanced, ensuring that the network device can select a suitable carrier to execute the direct link carrier and / or related resource scheduling in Mode 1, and can also avoid the network device allocating an invalid direct link carrier to the terminal, resulting in the terminal being unable to receive data due to monitoring the invalid direct link carrier, thereby solving the problem that the prior art cannot ensure the effective allocation of carriers and resources of SL in CA mode.

[0265] Optionally, after the terminal sends carrier information related to carrier aggregation of the first direct link to the network device, the method further includes:

[0266] The terminal receives second indication information sent by the network device; wherein the second indication information is used to indicate at least one of the following:

[0267] a second carrier set;

[0268] Layer 2 identification information, and a second carrier set corresponding to the layer 2 identification information;

[0269] A mapping relationship between a quality of service flow and a second carrier set;

[0270] Layer 2 identification information, and a quality of service flow corresponding to the layer 2 identification information;

[0271] The second carrier set includes at least one carrier that is usable by the terminal in the first direct link and is determined according to the carrier information.

[0272] Optionally, the second indication information can be carried in the same signaling as the first indication information, that is, when the network device configures the carrier and / or related resources that can be used by the terminal in the SL CA, it can explicitly or implicitly indicate the mapping relationship related to the carrier that can be used by the SL CA. Alternatively, the second indication information can also be carried in a different signaling from the first indication information, and the embodiments of the present application are not limited to this.

[0273] For example: when the first carrier set corresponding to the L2 ID or QoS flow is implicitly indicated in the carrier information reported by the terminal, the network device can first determine the first carrier set corresponding to the L2ID or QoS flow based on the carrier information reported by the terminal, and then, based on the first carrier set corresponding to the L2 ID or QoS flow, select the carrier and / or related resources that the terminal can use in SL CA.

[0274] Optionally, the information processing method further includes:

[0275] The terminal sends terminal capability information to the network device; wherein the terminal capability information is used to indicate whether the terminal supports carrier aggregation of the first direct link.

[0276] Optionally, the terminal capability information indicates whether the terminal supports carrier aggregation of the first direct link, which indicates whether a service or a transport block (Transport Block, TB) of the terminal can be transmitted on multiple carriers.

[0277] For example: if the terminal capability indication information reported by the terminal indicates that the terminal supports carrier aggregation of the first direct link, the network device may configure the terminal with carriers and / or related resources that can be used by SL CA, etc. Alternatively, if the terminal capability indication information reported by the terminal indicates that the terminal does not support carrier aggregation of the first direct link, the network device may configure the terminal with carriers and / or related resources that can be used by SL, etc., or it may depend on the network side implementation, and the embodiments of the present application are not limited thereto.

[0278] Optionally, the information processing method further includes:

[0280] Optionally, carrier management includes but is not limited to: adding a carrier, changing a carrier, releasing a carrier, etc.

[0289] Optionally, when the auxiliary information includes a reference signal measurement result of a radio resource corresponding to the third carrier set, the terminal sending the auxiliary information to the network device includes:

[0290] The terminal sends, to the network device, a reference signal measurement result of the radio resources corresponding to the third carrier set in a periodic manner;

[0291] or,

[0292] When the reference signal measurement result of the radio resources corresponding to the third carrier set meets the event triggering condition, the terminal sends the reference signal measurement result of the radio resources corresponding to the third carrier set to the network device.

[0293] In this embodiment, the terminal may send the reference signal measurement results of the wireless resources corresponding to the third carrier set to the network device on a periodic basis. It may also send the reference signal measurement results of the wireless resources corresponding to the third carrier set to the network device on an event basis. For example: the reference signal measurement result satisfies the event triggering condition, which may be that the reference signal measurement result of carrier X in the third carrier set is lower than the first threshold value, or the reference signal measurement result of carrier x in the third carrier set is lower than the preset threshold value and higher than the first threshold value, etc. The embodiments of the present application are not limited to this.

Or the network device can add, change or release the corresponding main carrier information (such as the main frequency, main BWP, etc.) when determining the main carrier information available on the first direct link, or the network device can add, change or release the corresponding auxiliary carrier information (such as the auxiliary frequency, auxiliary BWP, etc.) when determining the auxiliary carrier information available on the first direct link.

The two embodiments can refer to each other and can achieve the same technical effect. To avoid repetition, they will not be described here.

[0366] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0367] The information processing method of the present application is described below in conjunction with specific embodiments:

[0368] Embodiment 1:

[0369] like Figure 5 As shown, taking a base station as a network device as an example, a process of determining a carrier and / or a wireless resource of a carrier that can be used by a terminal SL CA is provided, specifically including:

[0370] Step 51: Terminal 1 (Tx UE) reports carrier information related to carrier aggregation of the first direct link to the base station;

[0371] The carrier information includes but is not limited to at least one of the following:

[0372] A first carrier set (or CA set); wherein the first carrier set includes at least one carrier usable by the terminal 1SL CA;

[0373] L2 ID, and CAset corresponding to the L2 ID;

[0374] The first mapping relationship includes a mapping relationship between a service type and a CAset, and a mapping relationship between the service type and an L2ID;

[0375] The second mapping relationship includes a mapping relationship between a QoS flow and a CA set, and a mapping relationship between the QoS flow and an L2ID;

[0376] The third mapping relationship includes a mapping relationship between a service type and a QoS flow, a mapping relationship between the service type and a CAset, and a mapping relationship between the QoS flow and an L2 ID.

[0377] Optionally, terminal 1 reports terminal capability information to the network device, where the terminal capability information is used to indicate whether terminal 1 supports SL CA. Here, whether terminal 1 supports SL CA refers to whether a service or a TB can be transmitted on multiple carriers.

[0378] Step 52: After obtaining the carrier information reported by terminal 1, the base station determines the carrier and / or related resources that terminal 1 can use in SL CA. For example, for CA set information corresponding to multiple L2 IDs of terminal 1, one or more common carriers in the CA set are selected for the current SL as the carrier (i.e., the first carrier) that can be used by terminal 1 in SL CA.

[0379] Optionally, when the terminal 1 also reports terminal capability information indicating whether the terminal supports SL CA, and the terminal capability information indicates that the terminal supports SL CA, the base station selects one or more carriers in common in the CAset for the current SL as carriers (i.e., the first carrier) that can be used by terminal 1 for SL CA.

[0380] Step 53: The base station sends first indication information (or scheduling information) to terminal 1, indicating the carriers available for SL CA and the corresponding SL grant resources allocated by the base station to terminal 1. For example, the first indication information or scheduling information may include the index value of the carrier, the corresponding time-frequency resource information, etc., but the embodiments of the present application are not limited thereto.

[0381] Step 54: After receiving the first indication information or scheduling information sent by the base station, terminal 1 selects the logical channel with the highest priority and the corresponding L2 ID based on the acquired time-frequency resource information, and sends the assembled MAC PDU to terminal 2 (RxUE).

[0382] Embodiment 2:

[0383] like Figure 6 As shown, taking a base station as a network device as an example, another process of the base station determining a carrier and / or a wireless resource of a carrier that can be used by a terminal SL CA is provided, specifically including:

[0384] Step 61: In Mode 1, the terminal reports carrier information related to carrier aggregation of the first direct link to the base station; wherein the carrier information includes L2 ID and QoS flow corresponding to the L2 ID.

[0385] Step 62: The base station determines the mapping relationship between L2 ID or QoS flow and CA set based on the carrier information reported by the terminal. CAset includes at least one carrier that can be used by the terminal SL CA. Based on this mapping relationship, the base station determines the carrier (i.e., the first carrier) that can be used by the terminal SL CA and the resource information on the carrier.

[0386] Optionally, the base station may send a second indication message to the network device, waiting for feedback from the terminal or an updated mapping relationship.
