Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to an information processing method, apparatus, terminal and network equipment. Background Art
[0002] In the existing technology, different channels use different beam indication signaling, and each channel performs beam indication independently. In this way, different channels may use different beams for transmission. However, an important scenario in practical applications is that multiple channels use the same beam direction. For example, some downlink control channels (PDCCH) used for resource scheduling and downlink data channels (PDSCH) used for transmitting user data use the same beam direction for transmission; some uplink control channels (PUCCH) and uplink data channels (PUSCH) also use the same beam direction. When beam reciprocity exists, uplink and downlink channels will also use the same beam direction. At this time, the current independent beam indication method increases system complexity and signaling indication overhead.

For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present application.
[0195] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to 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 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, acting as a router between the wireless terminal 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 (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a femto, a 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 geographically separated.
[0196] Network devices and terminals can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be either Single User MIMO (SU-MIMO) or Multi User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or Massive-MIMO. It can also use diversity transmission, precoding, or beamforming.
[0197] The following first introduces the contents involved in the solution provided in the embodiment of the present application.
[0198] In the NR (New Radio) system, downlink channels include the downlink data channel PDSCH and the downlink control channel PDCCH, and uplink channels include the uplink data channel PUSCH and the uplink control channel PUCCH. For high-frequency transmission (FR2 band in NR), due to the limited transmission range, the uplink and downlink channels are usually transmitted after beamforming to enhance coverage. The direction of the formed beam can be determined by beam scanning of the uplink and downlink reference signals, such as using CSI (Channel State Information)-RS (reference signal) or channel sounding reference signal SRS in different directions to perform beam scanning, and select the direction of the reference signal with the best beam quality for uplink or downlink transmission. After determining the beam direction of different channels, it is necessary to use signaling to indicate the beam when the channel is transmitted, that is, beam indication. In the NR Rel (version)-15 or 16 protocol, for the PUCCH channel, the base station semi-statically configures multiple beam directions to the terminal through the high-layer signaling SpatialRelationInfo, and activates one of them through MAC (Media Access Control)-CE (Control Element). For the PUSCH, the base station's selected uplink beam is indirectly indicated by the SpatialRelationInfo of the SRS resource indicated by the SRI (SRS Resource Indicator) field in the dynamic signaling DCI (Downlink Control Information). For the PDCCH channel, the base station configures multiple TCI (Transmission Configuration Indicator) states for each CORESET (Control Resource Set) through higher-layer signaling and activates one of them through the MAC-CE instruction. For the PDSCH channel, the base station indicates a TCI state through the TCI field in the DCI signaling, indicating the channel's beam direction.

For mode-1, in the downlink channel, CORESET2 and PDSCH use the same downlink beam (numbered B1); CORESET0 and CORESET1 use the same downlink beam (numbered B0); CSI-RS does not operate in mode-1. In the uplink channel, PUCCH and PUSCH use the same uplink beam (numbered C1), and SRS does not operate in mode-1.
[0307] The above beam numbers can be modified through MAC-CE. For example, the beam number of CORESET1 in mode-0 can be modified to A1, that is, {mode-0: A1}.
[0308] The base station configures a TCI state pool containing S=128 TCI-States for the terminal. Each state is indicated by a corresponding TCI-State Id. For example, the first TCI state is indicated by TCI-State0, the second TCI state is indicated by TCI-State1, and so on.
[0309] This solution can activate the TCI state from the TCI state pool configured by RRC (Radio Resource Control) through MAC-CE. This MAC-CE can contain a mode indication. If the MAC-CE indicates mode-0 at this time, it is a joint uplink and downlink beam mode. At the same time, this MAC-CE activates M-1 TCI state groups, that is, activates 2 TCI state groups, each state group contains 4 TCI states. State group 1 corresponds to the beam numbered A0, and state group 2 corresponds to the beam numbered A1 (the numbers corresponding to state groups 1 and 2 can be swapped). For example, through MAC-CE activation:
[0310] State group 1: TCI_State2, TCI_State5, TCI_State7, TCI_State9;
[0311] State group 2: TCI_State100, TCI_State112, TCI_State120, TCI_State126;
[0312] DCI is further used to select a beam from the above MAC-CE activated state group for indication. One approach is to use two-level DCI. The first-level DCI includes M-1=2 numbering fields, corresponding to numbers A0 and A1, where bit 0 indicates no beam indication and bit 1 indicates a beam indication. For example:
[0313] Number field (A0) Number field (A1) 0 1
[0314] This means that the second-level DCI only indicates the beam of A1. In this case, the second-level DCI contains a TCI field, which indicates the beam of A1. For example:
[0315] TCI domain 00
[0316] This indicates that the channel numbered A1 (associated) is transmitted using the beam corresponding to TCI_State100.
[0317] Alternatively, the first level DCI indicates:
[0318] Number field (A0) Number field (A1) 1 1
[0319] In this case, the second-level DCI contains two TCI fields, representing beams A0 and A1 respectively, for example:
[0320] TCI domain TCI domain 01 10
[0321] This indicates that the channel numbered A0 (associated) uses the beam corresponding to TCI_State5 for transmission, and the channel numbered A1 (associated) uses the beam corresponding to TCI_State120 for transmission.
[0322] Another indication method is to use the first-level DCI, which contains M-1=2 fixed TCI fields. The first field corresponds to the A0 beam, and the second field corresponds to the A1 beam. For example:
[0323] TCI domain TCI domain 11 10
[0324] This indicates that the channel numbered A0 (associated) uses the beam corresponding to TCI_State9 for transmission, and the channel numbered A1 (associated) uses the beam corresponding to TCI_State120 for transmission.
[0325] Another indication method is to use the first-level DCI, which contains a number field (corresponding to the beam number field) and a TCI field, where the number field indicates the number A0 or A1. For example:
[0326] Number field TCI domain 1 10
[0327] This indicates that the channel numbered A1 (associated) is transmitted using the beam corresponding to TCI_State7.
[0328] Example 2:
[0329] The beam association parameters of the channel and the reference signal are the same as those in Example 1 and are not repeated here.
[0330] The base station configures a TCI state pool containing S=128 TCI-States for the terminal. Each state is indicated by a corresponding TCI-State Id. For example, the first TCI state is indicated by TCI-State0, the second TCI state is indicated by TCI-State1, and so on.
[0331] This solution can activate the TCI state from the TCI state pool configured by RRC through MAC-CE. This MAC-CE can contain a mode indication. If MAC-CE indicates mode-1 at this time, it is an independent uplink and downlink beam mode. At the same time, this MAC-CE activates Q-1 TCI state groups, that is, activates 2 TCI state groups, each state group contains 4 TCI state combinations. State group 1 corresponds to the beam numbered {B0, C0}, and state group 2 corresponds to the beam numbered {B1, C1} (the numbers corresponding to state groups 1 and 2 can be swapped; the uplink and downlink can correspond to different state groups). For example, through MAC-CE activation:
[0332] State group 1: {TCI_State2, TCI_State12}, {TCI_State5, TCI_State15}, {TCI_State7, TCI_State17}, {TCI_State9, TCI_State19};
[0333] State group 2: {TCI_State100, TCI_State90}, {TCI_State120, TCI_State110}, {TCI_State112, TCI_State102}, {TCI_State126, TCI_State116};
[0334] DCI is further used to select a beam from the above-mentioned MAC-CE activated state group for indication. One approach is to use two-level DCI. The first-level DCI includes Q-1=N=2 numbering fields, corresponding to the numbers {B0, C0} and {B1, C1}, respectively. Bit 0 indicates no beam indication, and bit 1 indicates a beam indication. For example:
[0335] Number field Number field 0 1
[0336] This means that the second-level DCI only indicates the beam of {B1, C1}. In this case, the second-level DCI contains a TCI field, which indicates the beam of {B1, C1}. For example:
[0337] TCI domain 00
[0338] The remaining DCI indication methods can also be used similarly and will not be described in detail.
[0339] Example 3:
[0340] The system supports joint uplink and downlink beam modes and independent uplink and downlink beam modes, denoted as mode-0 and mode-1. For mode-0, the system pre-defines support for M = 3 beam numbers, denoted as A0, A1, and A2, where A2 indicates that the mode is invalid. For mode-1, the system pre-defines support for Q = 3 beam numbers for downlink, denoted as B0, B1, and B2, and pre-defines support for N = 3 beam numbers for uplink, denoted as C0, C1, and C2. For mode-1, B2 indicates that the mode is invalid (applicable to both uplink and downlink). For each channel and reference signal, two beam parameters, mode-0 and mode-1, are associated respectively.
[0341] The base station uses RRC signaling to configure channels and reference signals as follows:
[0342] PDCCH is transmitted through CORESET0, CORESET1 and CORESET2, and its associated beam parameters are configured as follows:
[0343] CORESET0: {mode-0: A0}, {mode-1: B0};
[0344] CORESET1:{mode-0:A0},{mode-1:B0};
[0345] CORESET2:{mode-0:A1},{mode-1:B1};
[0346] The beam parameter configuration associated with the PDSCH resource is:
[0347] PDSCH: {mode-0: A1}, {mode-1: B1};
[0348] The beam parameter configuration associated with the CSI-RS resource is:
[0349] CSI-RS: {mode-0: A2}, {mode-1: B2};
[0350] The beam parameter configuration associated with the PUCCH resource is:
[0351] PUCCH: {mode-0: A1}, {mode-1: C0};
[0352] The beam parameter configuration associated with the PUSCH resource is:
[0353] PUSCH: {mode-0: A1}, {mode-1: C1};
[0354] The beam parameter configuration associated with the SRS resource is:
[0355] SRS: {mode-0: A2}, {mode-1: C2}.
[0356] Based on the above configuration, it can be determined that for mode-0 operation, CORESET2, PDSCH, PUCCH, and PUSCH use the same beam (numbered A1); CORESET0 and CORESET1 use the same beam (numbered A0); and CSI-RS and SRS do not operate in mode-0. Their beams are configured using other methods, such as reusing independent configuration methods in Rel-15 or 16. For mode-1, in the downlink channel, CORESET2 and PDSCH use the same downlink beam (numbered B1); CORESET0 and CORESET1 use the same downlink beam (numbered B0); and CSI-RS does not operate in mode-1. In the uplink channel, PUCCH uses beam numbered C0, PUSCH uses uplink beam numbered C1, and SRS uses uplink beam numbered C2.
[0357] The base station configures a TCI state pool containing S=128 TCI-States for the terminal. Each state is indicated by a corresponding TCI-State Id. For example, the first TCI state is indicated by TCI-State0, the second TCI state is indicated by TCI-State1, and so on.
[0358] This solution can activate the TCI state from the TCI state pool configured by RRC through MAC-CE. This MAC-CE can include a mode indication. If MAC-CE indicates mode-1 at this time, it is an independent uplink and downlink beam mode. At the same time, this MAC-CE activates Q-1+N TCI state groups, that is, activates 5 TCI state groups, each state group contains 4 TCI states. State group 1 corresponds to the beam numbered B0, state group 2 corresponds to the beam numbered B1, state group 3 corresponds to the beam numbered C0, state group 4 corresponds to the beam numbered C1, and state group 5 corresponds to the beam numbered C2. For example, through MAC-CE activation:
[0359] State group 1: TCI_State2, TCI_State5, TCI_State7, TCI_State9;
[0360] State group 2: TCI_State12, TCI_State15, TCI_State17, TCI_State19;
[0361] State group 3: TCI_State22, TCI_State25, TCI_State27, TCI_State29;
[0362] State group 4: TCI_State100, TCI_State112, TCI_State120, TCI_State126;
[0363] State group 5: TCI_State90, TCI_State102, TCI_State110, TCI_State116;
[0364] DCI is further used to select a beam from the above-mentioned MAC-CE activated state group for indication. One approach is to use two-level DCI. The first-level DCI includes Q-1+N=5 numbering fields, corresponding to numbers B0, B1, C0, C1, and C2, where bit 0 indicates no beam indication and bit 1 indicates a beam indication. For example:
[0365] Number field (B0) Number field (B1) Number field (C0) Number field (C1) Number field (C2) 0 1 0 1 0
[0366] This means that the second-level DCI only indicates the beams B1 and C1. In this case, the second-level DCI contains two TCI fields, which represent the beams B1 and C1. For example:
[0367] TCI domain TCI domain 00 11
[0368] This indicates that the channel numbered B1 (associated) uses the beam corresponding to TCI_State12 for transmission, and the channel numbered C1 (associated) uses the beam corresponding to TCI_State126 for transmission.
[0369] Another indication method is to use the first-level DCI, which contains Q-1+N=5 fixed TCI fields. The first field corresponds to the B0 beam, the second field corresponds to the B1 beam, and the second field corresponds to the C0, C1, and C2 beams in sequence. For example:
[0370] TCI domain TCI domain TCI domain TCI domain TCI domain 01 10 11 10 11
[0371] Another indication method is to use the first-level DCI. It contains a number field (corresponding to the beam number field) and a TCI field. The number field indicates at least one of the numbers B0, B1, C0, C1 and C2. For example:
[0372] Number field TCI domain 001 10
[0373] This indicates that the channel numbered B1 is transmitted using the beam corresponding to TCI_State17.
[0374] The difference between Example 3 and Example 2 is that: in Example 2, the number of uplink and downlink beam numbers is the same, and both have an invalid number B2; in Example 3, the downlink beam number is one less than the uplink beam number; in Example 2, the uplink and downlink beam pairs are indicated together; in Example 3, the uplink and downlink beams are indicated separately.
[0375] Example 4:
[0376] The beam association parameters of the channel and the reference signal are the same as those in Example 3 and are not repeated here.
[0377] The base station configures a TCI state pool containing S=128 TCI-States for the terminal. Each state is indicated by a corresponding TCI-State Id. For example, the first TCI state is indicated by TCI-State0, the second TCI state is indicated by TCI-State1, and so on.
[0378] This solution can activate the TCI state from the TCI state pool configured by RRC through MAC-CE. This MAC-CE can include a mode indication. For example, if the MAC-CE indicates mode-1, it is an independent uplink and downlink beam mode. At the same time, this MAC-CE activates one TCI state group, each of which contains four TCI state combinations. Each TCI state combination corresponds to beams numbered B0, B1, C0, C1, and C2. For example, through MAC-CE activation:
[0379] State group: {TCI_State2, TCI_State5, TCI_State7, TCI_State9, TCI_State13};
[0380] {TCI_State12,TCI_State15,TCI_State17,TCI_State19,TCI_State23};
[0381] {TCI_State22, TCI_State25, TCI_State27, TCI_State29, TCI_State33};
[0382] {TCI_State100,TCI_State112,TCI_State120,TCI_State126,TCI_State83}.
[0383] The DCI is further used to select a beam from the above MAC-CE activated state group for indication. The DCI indication signaling at this time includes a TCI field, whose value is used to simultaneously indicate the five numbered beams.
[0384] It is noted here that in an embodiment of the present application: in the independent uplink and downlink beam mode, the uplink and downlink beams (i.e., TCI status) can be indicated separately or together, and there is no limitation here.
[0385] As can be seen from the above, this solution involves a beam indication method that associates a beam number with each channel and / or reference signal. MAC-CE or DCI can be used to indicate the corresponding beam for channels and / or reference signals with different beam numbers. This solution reduces beam indication signaling overhead and system complexity while ensuring a certain degree of beam flexibility.
[0386] The present application also provides a terminal, such as Figure 4 As shown, it includes a memory 41, a transceiver 42, and a processor 43:
[0387] The memory 41 is used to store computer programs; the transceiver 42 is used to send and receive data under the control of the processor 43; the processor 43 is used to read the computer program in the memory 41 and perform the following operations:

[0390] The beam indication signaling includes: at least one activated transmission configuration indication TCI state group;
