Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication processing method, apparatus, communication equipment, and processor-readable storage medium. Background Art

[0002] In the downlink (DL) coverage transmission, since message 2 (MSG2) needs to be transmitted repeatedly, the random access response (RAR) window needs to be extended. However, in the prior art, the calculation of the random access radio network temporary identity (RA-RNTI) is based on the non-extended RAR window. When multiple terminals send preambles in different time slots, the calculated RA-RNTI is the same, which leads to RA-RNTI collision and increases the number of blind detections of the terminal.

[0096] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The information processing method, device, and communication node provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system).

[0097] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1 As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device).

It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0098] In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced.

[0099] 1) Four-step random access process.

[0100] See also Figure 2 ,The specific steps of four-step random access are as follows:

[0101] Step 1: The terminal sends the first message (MSG1), that is, transmits a random access preamble, and opens a RAR window after sending the preamble.

[0102] Step 2: In the RAR window, the second message (MSG2), i.e., RAR, is received. After the terminal successfully receives the RAR, the RAR window is closed, wherein the RAR carries the uplink grant (UL grant) available for transmitting the message 3 (MSG3). The RAR is carried by the physical downlink shared channel (PDSCH) indicated by the physical downlink control channel (PDCCH) scrambled by the RA-RNTI.

[0103] Among them, RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id;

[0104] Where s_id represents the first orthogonal frequency division multiplexing (OFDM) symbol index of a physical random access channel (PRACH) occasion (0≤s_id<14). When μ={0,1,2,3}, t_id represents the first time slot index of the PRACH occasion in a system frame (0≤t_id<80); when μ={5,6}, t_id represents the index of the 120KHz time slot in the system frame containing the PRACH occasion (0≤t_id<80). f_id represents the index of the PRACH occasion in the frequency domain (0≤f_id<8). At the same time, ul_carrier_id is used to indicate the UL carrier of the preamble transmission, 0 represents the NUL carrier, and 1 represents the SUL carrier.

[0105] Step 3: The terminal sends a third message (MSG3) according to the UL grant in the RAR, and opens a contention resolution window after sending MSG3.

[0106] Step 4: The terminal receives the fourth message (MSG4) within the contention resolution window. When the random access contention is successfully resolved, the terminal stops the contention resolution window and completes the random access process.

[0107] 2) RAR repetition.

[0108] In order to improve the success probability of RAR reception, a method of repeatedly sending RAR is proposed in the related art. One method of indicating the number of RAR repetitions is to indicate the number of RAR repetitions in downlink control information (DCI).

[0109] Since the calculation of RA-RNTI in the prior art is based on the non-extended RAR window, the following problems may arise:

[0110] Question 1:

[0111] like Figure 3 As shown, if the existing RA-RNTI calculation formula is used, the conventional (legacy) terminal will receive the RAR sent by the network side for the legacy terminal in the non-extended RAR window, and will also receive the RAR for the RAR repeated transmission terminal, thereby increasing the number of terminal blind detections.

[0112] Similarly, the terminal that repeatedly transmits RAR will also receive the RAR sent by the network side to the legacy terminal in the RAR window, and will also receive the RAR for the terminal that repeatedly transmits RAR. Similarly, the number of blind detections increases.

[0113] Question 2:

[0114] like Figure 4 As shown, terminals with different RAR repetition times all receive RAR in the same RAR window, so that terminals receiving different RAR repetition times receive RAR using the same RA-RNTI, especially when the RAR repetition number is indicated by the PDCCH repetition number, which greatly increases the number of blind detections of the terminal.

[0115] Based on the analysis, the embodiments of the present application provide a communication processing method, apparatus, communication equipment and processor-readable storage medium to solve the problem of increasing the number of blind detection times of the terminal when multiple terminals send preamble codes in different time slots because the calculated RA-RNTI is the same.

[0116] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0117] See also Figure 5 , an embodiment of the present application provides a communication processing method, which is executed by a terminal, and the specific steps include: step 501.

[0118] Step 501: after sending a first message, determining a first RA-RNTI according to the following method, wherein the first RA-RNTI is used to scramble a first PDCCH, and the first PDCCH is used to indicate a random access response (Random Access Response, RAR);

[0119] First RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+offset;

[0120] Wherein, s_id represents the first orthogonal frequency division multiplexing OFDM symbol index of a physical random access channel (PRACH) opportunity;

[0121] t_id represents the first timeslot index of a PRACH opportunity in a system frame, or represents the index of a 120 kHz timeslot in a system frame containing a PRACH opportunity;

[0122] f_id represents the index of the PRACH opportunity in the frequency domain;

[0123] ul_carrier_id indicates the uplink carrier of the preamble transmission;

[0124] The offset is used to indicate the offset information of RA-RNTI calculation under different RAR window lengths.

[0125] In one implementation manner of the present application, the offset is determined in the following manner: the offset=14×80×8×N, where N is an integer greater than or equal to 4.

[0126] In one implementation, the N is notified by a broadcast message.

[0127] In another embodiment, the N is determined in the following manner: the N=floor[RAR window length / 10].

[0128] In one embodiment of the present application, the RAR window length is related to the reference signal received power RSRP value obtained by the terminal measuring the synchronization signal block (Synchronization Signal / PBCH Block, SSB) / channel state information reference signal (Channel-StateInformation Reference Signal, CSI-RS). For example, the network side notifies multiple RSRP threshold values, and each threshold value range corresponds to a RAR window length. For example, when the RSRP value measured by the terminal is less than RSRP1, the corresponding RAR window length is RARWindow1, and when the RSRP value measured by the terminal is between [RSRP1, RSRP2], the corresponding RAR window length is RARWindow2.

[0129] Optionally, RAR window can be used for legacy RAR, or for RAR duplicates.

[0130] In an implementation manner of the present application, the offset = M, or the offset = 14×80×8×M, where M is used to indicate offset information of RA-RNTI calculation under different RAR window lengths.

[0131] In one implementation, the M is notified by a broadcast message.

[0132] In another implementation manner, the value of M is related to the RSRP value measured by the terminal or the RAR window length selected by the terminal.

[0133] In one implementation of the present application, the first message includes a random access preamble code or the first message is message A.

[0134] In one implementation of the present application, after sending the first message to the network side device, the method further includes:

[0135] Receive a second message repeatedly transmitted by the network side device.

[0136] Optionally, when the first message is message A, the second message is message B.

[0137] In one implementation of the present application, after sending the first message to the network side device, the method further includes:

[0138] A PRACH resource corresponding to the repeated transmission RAR is selected.

[0139] In this embodiment, after sending the first message, the terminal determines the first RA-RNTI according to the following formula: first RA-RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id + offset, where the first RA-RNTI is used to scramble the first PDCCH, and the first PDCCH is used to indicate RAR, so that each terminal can calculate a reasonable first RA-RNTI, thereby avoiding an increase in the number of blind RAR detections by the terminal.

[0140] See also Figure 6 , an embodiment of the present application provides a communication processing method, which is executed by a network side device, and the specific steps include: Step 601.

[0141] Step 601: Sending RAR via a first PDCCH scrambled by a first RA-RNTI;

[0142] The first RA-RNTI is determined in the following manner:

[0143] First RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+offset;

[0144] s_id represents the first orthogonal frequency division multiplexing OFDM symbol index of a physical random access channel PRACH opportunity;

[0145] t_id represents the first timeslot index of a PRACH opportunity in a system frame, or represents the index of a 120 kHz timeslot in a system frame containing a PRACH opportunity;

[0146] f_id represents the index of the PRACH opportunity in the frequency domain;

[0147] ul_carrier_id indicates the uplink carrier of the preamble transmission;

[0148] The offset is used to indicate the offset information of RA-RNTI calculation under different RAR window lengths.

[0149] In one implementation manner of the present application, the offset=14×80×8×N, where N is an integer greater than or equal to 4.

[0150] In one implementation of the present application, N=floor[RAR window length / 10].

[0151] In one implementation of the present application, the RAR window length is related to the RSRP value of the terminal.

[0152] In an implementation manner of the present application, the offset = M, or the offset = 14×80×8×M, where M is used to indicate offset information of RA-RNTI calculation under different RAR window lengths.

[0153] Optionally, the M is notified by a broadcast message, or the value of the M is related to the RSRP value of the terminal or the RAR window length selected by the terminal.

[0154] In this embodiment, the network side device sends RAR to the terminal through the first PDCCH encrypted by the first RA-RNTI, where the first RA-RNTI is determined according to the following formula: first RA-RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id + offset, so that each terminal can calculate a reasonable first RA-RNTI, thereby avoiding an increase in the number of blind RAR detections by the terminal.

[0155] Embodiment 1: The first RA-RNTI is related to 14×80×8.

[0156] Step 1: The network side device sends the first configuration information.

[0157] Optionally, the first configuration information includes at least one of the following:

[0158] (1) One or more first PRACH resources. When the terminal sends a preamble in the first PRACH resource, it indicates that the terminal supports RAR repetition.

[0159] (2) one or more first thresholds, the terminal selects the PRACH resource according to the first threshold, and the optional first threshold may be an RSRP threshold;

[0160] (3) first RAR window length;

[0161] Optionally, the first RAR window corresponds to the first threshold.

[0162] (4) a first parameter (i.e., N), which is an integer greater than or equal to 4;

[0163] Optionally, the value of the first threshold may correspond to the value of the threshold of message 3 repetition transmission (MSG3 repetition).

[0164] Optionally, the first PRACH resource is the same as the PRACH resource corresponding to the repeated transmission of message 3.

[0165] Step 2: The terminal selects a PRACH resource according to the first configuration information;

[0166] For example, the terminal determines whether the current RSRP value is lower than the first threshold. If it is lower than the first threshold, the terminal selects the first PRACH resource to send a preamble. Optionally, the terminal may perform PRACH repetition transmission.

[0167] Step 3: The terminal opens the RAR window.

[0168] Optionally, the RAR window length is greater than 10 ms.

[0169] Optionally, the terminal selects the RAR window length according to the RSRP threshold. Optionally, the network device may configure multiple RSRP thresholds and the RAR window lengths corresponding to multiple RSRP intervals.

[0170] For example, RSRP1 < RSRP2 < RSRP3. For the interval less than RSRP1, the RAR window length is selected as RARWindow1. For the interval [RSRP1, RSRP2], the RAR window length is selected as RARWindow2. For the interval [RSRP2, RSRP3], the corresponding RARWindow3 is selected as the RAR window length. For the interval greater than RSRP3, the terminal selects RARWindow4. Optionally, RARWindow4 may be equal to 10 ms.

[0171] Step 4: The terminal listens for the RAR scrambled with the first RA-RNTI within the RAR window.

[0172] Among them, the calculation formula for the first RA-RNTI is:

[0173] The first RA-RNTI = 1 + s_id + 14×t_id + 14×80×f_id + 14×80×8×ul_carrier_id + 14×80×8×N.

[0174] The above N is an integer greater than or equal to 4.

[0175] Optionally, N may be notified by the first configuration information in Step 1, or N may also be predefined. Considering that the current maximum value of RA-RNTI / MSGB-RNTI is 14×80×8×4. Therefore, when N is greater than or equal to 4, it can ensure that the newly calculated first RA-RNTI value does not conflict with the original RA-RNTI value. This can reduce the blind detection times of legacy UEs and terminals with RAR repeated transmission.

[0176] Embodiment 2: The calculation formula of the first RA-RNTI is related to the RAR window.

[0177] Step 1: The network device sends the first configuration information.

[0178] Optionally, the first configuration information includes at least one of the following:

[0179] (1) One or more first PRACH resources. When the terminal sends a preamble on the first PRACH resource, it indicates that the terminal supports RAR repetition;

[0180] (2) One or more first thresholds. The terminal selects a PRACH resource through the first threshold. Optionally, the first threshold can be an RSRP threshold;

[0181] (3) The first RAR window length; optionally, the first RAR window corresponds to the first threshold;

[0182] Optionally, the value of the first threshold can correspond to the value of the threshold for message 3 retransmission.

[0183] Optionally, the first PRACH resource is the same as the PRACH resource corresponding to message 3 retransmission.

[0184] Step 2: The terminal selects a PRACH resource according to the first configuration information;

[0185] For example, the terminal determines whether the current RSRP value is lower than the first threshold. If it is lower than the first threshold, the terminal selects the first PRACH resource to send a preamble. Optionally, the terminal can perform PRACH repetition transmission.

[0186] Step 3: The terminal opens the RAR window.

[0187] Optionally, the RAR window length is greater than 10 ms. Optionally, the terminal selects the RAR window length according to the RSRP threshold. Optionally, the network-side device can configure multiple RSRP thresholds and RAR window lengths corresponding to multiple RSRP intervals.

[0188] For example, RSRP1 < RSRP2 < RSRP3. For the interval less than RSRP1, the RAR window length is selected as RARWindow1. For the interval [RSRP1, RSRP2], the RAR window length is selected as RARWindow2. For the interval [RSRP2, RSRP3], the corresponding RARWindow3 is selected for the RAR window length. For the interval greater than RSRP3, the terminal selects RARWindow4. Optionally, RARWindow4 can be equal to 10 ms.

[0189] Step 4: The terminal listens for the RAR scrambled with the first RA-RNTI within the RAR window.

[0190] Among them, the calculation formula for the first RA-RNTI is:

[0191] First RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×N;

[0192] Wherein N=floor[RAR window / 10], that is, when the selected RAR window is different, the value of N is different, and the selection of the RAR window is related to the RSRP value, so that different RSRP values ​​can be ensured, and the calculated first RA-RNTI is a different value, thereby reducing the number of blind detections.

[0193] Embodiment 3: RA-RNTI is related to a constant.

[0194] Step 1: The network side device sends the first configuration information.

[0195] Optionally, the first configuration information includes at least one of the following:

[0196] (1) One or more first PRACH resources. When the terminal sends a preamble in the first PRACH resource, it indicates that the terminal supports RAR repetition.

[0197] (2) one or more first thresholds, the terminal selects the PRACH resource according to the first threshold, and the optional first threshold may be an RSRP threshold;

[0198] (3) first RAR window length;

[0199] Optionally, the first RAR window corresponds to the first threshold;

[0200] (4) A second parameter (M), which is used to indicate an offset for RA-RNTI calculation under different RAR window lengths.

[0201] Optionally, the value of the first threshold may correspond to the value of the threshold for repeated transmission of message 3.

[0202] Optionally, the first PRACH resource is the same as the PRACH resource corresponding to the repeated transmission of message 3.

[0203] Step 2: The terminal selects a PRACH resource according to the first configuration information;

[0204] For example, the terminal determines whether the current RSRP value is lower than a first threshold. If it is lower than the first threshold, the terminal selects a first PRACH resource to send a preamble. Optionally, the terminal may perform PRACH repetition transmission.

[0205] Step 3: Open the RAR window in the terminal;

[0206] Optionally, the RAR window length is greater than 10 ms. Optionally, the terminal selects the RAR window length according to the RSRP threshold. Optionally, the network device may configure multiple RSRP thresholds and the corresponding RAR window lengths for multiple RSRP intervals.

[0207] For example, RSRP1 < RSRP2 < RSRP3. For the interval less than RSRP1, the RAR window length is selected as RARWindow1; for the interval [RSRP1, RSRP2], the RAR window length is selected as RARWindow2; for the interval [RSRP2, RSRP3], the RAR window length is selected as the corresponding RARWindow3; for the interval greater than RSRP3, the terminal selects RARWindow4. Optionally, RARWindow4 may be equal to 10 ms.

[0208] Step 4: The terminal listens for the RAR scrambled by the first RA-RNTI within the RAR window.

[0209] Among them, the calculation formula for the first RA-RNTI is:

[0210] The first RA-RNTI = 1 + s_id + 14×t_id + 14×80×f_id + 14×80×8×ul_carrier_id + M; or

[0211] The first RA-RNTI = 1 + s_id + 14×t_id + 14×80×f_id + 14×80×8×ul_carrier_id + 14×80×8×M.

[0212] The above M may be associated with different RSRPs or different RAR windows; or M may also be notified by the first configuration information in Step 1.
