Technical Field

Background

When a communication link is established between the terminal device and the network device, there is a procedure in which the terminal device randomly accesses the network. In the random access process, the terminal device sends a signal such as a physical random access channel (physical random access channel, PRACH) to the network device, and a signaling 1 (message 1, msg 1) carried by the PRACH carries a random access preamble.

If the uplink coverage in the random access process is weaker, the signal received by the network device from the terminal device may be weaker, or even the signal from the terminal device cannot be received, which may cause the random access failure of the terminal device. How to enhance uplink coverage in random access procedure is a challenge.

Referring to fig. 2, fig. 2 is a flowchart of a random access processing method 100 according to an embodiment of the application. The random access processing method 100 may be performed by a terminal device. The random access processing method 100 includes the steps of:

S101, terminal equipment selects N reference signals from a plurality of reference signals, wherein N is an integer greater than or equal to 0. The reference signal may be a downlink reference signal, such as a channel state information reference signal (channel state information reference signal, CSI-RS) or a synchronization signal block (synchronization signal block, SSB). Alternatively, the reference signal is configured by the network side through higher layer signaling, which may be a downlink reference signal for the transmission of the associated Msg 1.

S102, the terminal equipment determines the repeated transmission times M1 of the random access message according to the beams associated with the N reference signals, wherein M1 is an integer greater than 1. Wherein the beam associated with each reference signal may be a beam, such as a receive beam, employed by the terminal device to receive the reference signal.

S103, the terminal equipment sends the random access message according to the repeated transmission times M1.

The random access message may be a signaling 1 (message 1, msg 1) carried by a physical random access channel (physical random access channel, PRACH).

The determination manner regarding the number of repeated transmissions M1 includes, but is not limited to, those described in embodiment a to embodiment I.

In embodiment a, if N is equal to the number of repeated transmissions of a random access message configured by a network device, the N reference signals are N reference signals with the largest reference signal received power (reference signal receiving power, RSRP) among the plurality of reference signals, or the N reference signals are N reference signals with the largest signal-to-noise ratio (signal to interference plus noise ratio, SINR) among the plurality of reference signals; accordingly, M1 is equal to N. The number of repeated transmissions of the random access message configured by the network device may be sent by the network device to the terminal device.

In step S103, the terminal device uses the number of repeated transmissions M1, and the beam used when transmitting the random access message is the beam associated with the N reference signals. It can be seen that the terminal device can use different beams to send the random access message with the repeated transmission times M1, so as to realize repeated sending of the random access message for multiple times, and enhance uplink coverage in the random access process.

In the embodiment B, the N reference signals are reference signals having RSRP or SINR greater than a preset value among the plurality of reference signals; if N is greater than or equal to the number of repeated transmissions of the random access message configured by the network device, M1 is equal to the number of repeated transmissions of the random access message configured by the network device. Wherein the preset value may be configured or predefined by higher layer signaling.

For example, the number of repeated transmissions of the random access message configured by the network device is 6, and the number of reference signals with RSRP or SINR greater than the preset value among the plurality of reference signals is 7 (i.e., the value of N), then the number of repeated transmissions M1 is 6.

Optionally, in step S103, the beam adopted by the terminal device when sending the random access message with the number of repeated transmissions M1 may be a beam associated with any M1 reference signals in the N reference signals, or may be a beam associated with M1 reference signals with the largest RSRP or SINR in the N reference signals. It can be seen that the terminal device can adopt different beams to transmit the random access message with the repeated transmission times M1, so as to realize repeated transmission of the random access message for multiple times and enhance uplink coverage in the random access process.

In the embodiment C, the N reference signals are reference signals having RSRP or SINR greater than a preset value among the plurality of reference signals; if N is less than the number of repeated transmissions of the random access message configured by the network device and N is greater than or equal to the minimum value in the first set, M1 is equal to the maximum value in the values not greater than N in the first set; the first set includes a plurality of values that allow selection of the number of repeated transmissions, and the plurality of values are integers greater than or equal to 1. Wherein the preset value may be configured or predefined by higher layer signaling.

For example, the first set includes a plurality of values: 2. 4, 6, 8, the number of repeated transmissions of the random access message configured by the network device is 6, and the number of reference signals with RSRP or SINR greater than a preset value in the plurality of reference signals is 5 (i.e. the value of N). It can be seen that the values of not more than 5 in the first set include 2 and 4, of which the maximum value is 4, and then the number of repeated transmissions M1 is equal to 4.

Optionally, in step S103, the beam adopted by the terminal device when sending the random access message with the number of repeated transmissions M1 is a beam associated with any M1 reference signals in the N reference signals, and may also be a beam associated with M1 reference signals with the largest RSRP or SINR in the N reference signals. It can be seen that the terminal device can adopt different beams to transmit the random access message with the repeated transmission times M1, so as to realize repeated transmission of the random access message for multiple times, and further enhance uplink coverage in the random access process.

In the embodiment of the present application, the first set may be configured to the terminal device by the network device through a higher layer signaling, or may be predefined. Optionally, the plurality of values in the first set correspond to the same preset value, or the plurality of values in the first set each correspond to a different preset value.

In embodiment D, the N reference signals are reference signals in which RSRP or SINR of the plurality of reference signals is greater than a preset value, where the preset value may be configured or predefined by higher layer signaling; if N is greater than or equal to the minimum value in the first set, M1 is equal to the maximum value of the values in the first set that are not greater than N; the first set includes a plurality of values that allow selection of the number of repeated transmissions, and the plurality of values are integers greater than or equal to 1. Wherein the preset value may be configured or predefined by higher layer signaling.

For example, the first set includes a plurality of values: 2. 4, 6, 8, the number of reference signals having RSRP or SINR greater than a preset value among the plurality of reference signals is 5 (i.e., the value of N). It can be seen that the values of not more than 5 in the first set include 2 and 4, of which the maximum value is 4, and then the number of repeated transmissions M1 is equal to 4.

In embodiment E, the N reference signals are reference signals having RSRP or SINR greater than a preset value among the plurality of reference signals; if N is less than the number of repeated transmissions of the random access message configured by the network device and N is also less than the minimum value in the first set, M1 is equal to the minimum value in the first set; the first set includes a plurality of values that allow selection of the number of repeated transmissions, and the plurality of values are integers greater than or equal to 1. Wherein the preset value may be configured or predefined by higher layer signaling.

For example, the first set includes a plurality of values: 2. 4, 6, 8, the number of repeated transmissions of the random access message configured by the network device is 6, and the number of reference signals with RSRP or SINR greater than a preset value in the plurality of reference signals is 1 (i.e. the value of N). It can be seen that N is smaller than the number of repeated transmissions of the random access message configured by the network device and N is also smaller than the minimum value in the first set, then the number of repeated transmissions M1 is equal to the minimum value in the first set, i.e. M1 is equal to 2.

Optionally, in step S103, the beam adopted by the terminal device when sending the random access message with the number of repeated transmissions M1 is a beam associated with any M1 reference signals in the N reference signals, and may also be a beam associated with M1 reference signals with the largest RSRP or SINR in the N reference signals. It can be seen that the terminal device can use different beams to send the random access message with the repeated transmission times M1, so as to realize repeated sending of the random access message for multiple times, and enhance uplink coverage in the random access process.

In embodiment F, the N reference signals are reference signals in which RSRP or SINR of the plurality of reference signals is greater than a preset value, where the preset value may be configured or predefined by higher layer signaling; if N is also less than the minimum value in the first set, M1 is equal to the minimum value in the first set; the first set includes a plurality of values that allow selection of the number of repeated transmissions, and the plurality of values are integers greater than or equal to 1.

For example, the first set includes a plurality of values: 2. 4, 6, 8, the number of reference signals having RSRP or SINR greater than a preset value among the plurality of reference signals is 1 (i.e., the value of N). It can be seen that N is smaller than the number of repeated transmissions of the random access message configured by the network device and N is also smaller than the minimum value in the first set, then the number of repeated transmissions M1 is equal to the minimum value in the first set, i.e. M1 is equal to 2.

In embodiment G, the N reference signals are reference signals having RSRP or SINR greater than a preset value among the plurality of reference signals, where the preset value may be configured or predefined by higher layer signaling. If N is smaller than the number of repeated transmission times of the random access message configured by the network equipment, M1 is equal to the number of repeated transmission times of the random access message configured by the network equipment, and the terminal equipment adopts the same wave beam when transmitting the random access message with the number of repeated transmission times M1. That is, when the number of reference signals with RSRP or SINR greater than a preset value among the plurality of reference signals is smaller than the number of repeated transmissions of the random access message configured by the network device, the terminal device transmits the random access message by using the same beam according to the number of repeated transmissions of the random access message configured by the network device.

The selection of the same beam may refer to selecting a beam satisfying any one of the reference signals having RSRP or SINR greater than a preset value, or selecting a beam satisfying one of the reference signals having RSRP or SINR greater than a preset value, which is the largest, or randomly selecting one of the reference signals if the reference signal having RSRP or SINR greater than the preset value is not satisfied.

For example, the number of repeated transmissions of the random access message configured by the network device is 6, and the number of reference signals with RSRP or SINR greater than the preset value in the plurality of reference signals is 5 (i.e., the value of N), where N is smaller than the number of repeated transmissions of the random access message configured by the network device, and then the terminal device uses the same beam to repeat 6 times to send the random access message.

In a variation, taking the random access message as Msg1 as an example, if the terminal device cannot complete the random access procedure after performing Msg1 retransmission X times with different beams, the terminal device returns to the manner of performing Msg1 retransmission with the same beam. Where X may be configured by the network layer through higher layer signaling or its value may be predefined.

In a variation, taking the random access message as Msg1 as an example, if the terminal device still causes the random access procedure failure after performing the Msg1 retransmission with a different beam, the terminal device rolls back to the manner of performing the Msg1 retransmission with the same beam. Where X may be configured by the network layer through higher layer signaling or its value may be predefined.

In embodiment H, if there is no reference signal with RSRP or SINR greater than a preset value among the plurality of reference signals, the terminal device uses M1 beams randomly selected from the beams associated with the plurality of reference signals when transmitting the random access message with the number of repeated transmissions M1, and the terminal device does not transmit status information of the M1 beams.

In embodiment I, if the number of reference signals with RSRP or SINR greater than the preset value in the plurality of reference signals is smaller than the required number, M1 is equal to the required number, and the terminal device randomly selects M1 reference signals from the plurality of reference signals, or the terminal device selects M1 reference signals with the largest RSRP or SINR from the plurality of reference signals. Wherein, the required number can be the repeated transmission times configured by the network equipment and can be predefined; the preset value may be configured by higher layer signaling or predefined.

In addition, the method of determining the beam adopted when the terminal device sends the random access message in the above embodiments may also be applied to determining the new beam (new beam) in the beam fault recovery (beam failure recovery, BFR) process. Specifically, the number of new beams indicated is T1, and the new beams include: the T1 reference signal associated beams with the largest RSRP or SINR among the plurality of reference signals. Or when the number T2 of reference signals with RSRP or SINR greater than a preset value in the plurality of reference signals is greater than or equal to T1, the new beam includes: and a beam associated with T1 reference signals selected from T2 reference signals with RSRP or SINR larger than a preset value. Alternatively, when T2 is less than T1 and T2 is greater than or equal to the minimum value in the first set, the new beam comprises: the beam associated with T3 reference signals selected from the T2 reference signals having RSRP or SINR greater than a preset value, T3 being equal to the maximum value of the values not greater than T1 in the first set. Alternatively, when T2 is less than T1 and T2 is also less than the minimum in the first set, the new beam comprises: the beam associated with T4 reference signals selected from the T2 reference signals having RSRP or SINR greater than a preset value, T4 being the minimum value in the first set. Or when T2 is smaller than T1, the method returns to the mode of transmitting the message by adopting the same wave beam. Or when T2 is smaller than T1, the new wave beam is randomly selected from the wave beams associated with T2 reference signals with RSRP or SINR larger than a preset value, and the state information of the new wave beam is not reported.

In summary, in the random access processing method 100, the terminal device selects N reference signals from the plurality of reference signals, where N is an integer greater than or equal to 0; the terminal equipment determines the repeated transmission times M1 of the random access message according to the beams associated with the N reference signals, wherein M1 is an integer greater than 1; the terminal device sends the random access message with the repeated transmission times M1. The random access processing method 100 realizes that the terminal equipment repeatedly sends the random access message for a plurality of times, enhances uplink coverage in the random access process, and can improve the success rate of random access of the terminal equipment.

Referring to fig. 3, fig. 3 is a flowchart of a random access processing method 200 according to an embodiment of the application. The random access processing method 200 may be performed by a terminal device. The random access processing method 200 includes the steps of:

s201, the terminal equipment determines the repeated transmission times M1 of the random access message from the first set; the first set includes a plurality of values that are allowed to be selected for the number of repeated transmissions, and the plurality of values are integers greater than 1. Wherein the first set may be configured by the network device to the terminal device through higher layer signaling, or may be predefined.

Optionally, when the terminal device determines the number of repeated transmissions M1 of the random access message from the first set, the terminal device may further determine the number of repeated transmissions M1 of the random access message in combination with RSRP situations of a plurality of reference signals. For example, when the number of reference signals with RSRP smaller than a preset value in the plurality of reference signals is smaller than a first value, selecting a larger value from the first set as the repeated transmission number M1; otherwise, a smaller value is selected from the first set as the number of repeated transmissions M1. The preset value and/or the first value may be indicated by the network device through higher layer signaling, or may be predefined.

S202, the terminal equipment sends the random access message according to the repeated transmission times M1.

In addition, the random access processing method 200 may also be applied to a case that the network device does not configure the number of repeated transmissions of the random access message for the terminal device, where the terminal device defaults that a plurality of values in the first set are all available, and selects a value from the first set as the number of repeated transmissions of the random access message.

s301, the terminal equipment determines the repeated transmission times M1 of the random access message according to reference signal received power RSRP of a plurality of reference signals; m1 is an integer greater than 1.

Optionally, the terminal device may determine the larger number of repeated transmissions M1 when RSRP of the plurality of reference signals is generally smaller; when the RSRP of the plurality of reference signals is generally larger, a smaller number M1 of repeated transmissions is determined. For example, when the number of reference signals with RSRP smaller than a preset value in the plurality of reference signals is smaller than a first value, determining a larger repeated transmission number M1; otherwise, a smaller number of repeated transmissions M1 is determined. The preset value and/or the first value may be indicated by the network device through higher layer signaling, or may be predefined.

S302, the terminal equipment sends the random access message according to the repeated transmission times M1.

In the random access processing method 300, the terminal device may autonomously determine the number of repeated transmissions M1 of the random access message according to RSRP of the plurality of reference signals. The random access processing method 300 can realize that the terminal equipment repeatedly sends the random access message for a plurality of times, thereby enhancing uplink coverage in the random access process and improving the success rate of the random access of the terminal equipment.

Optionally, taking the random access message as Msg1 as an example, when Msg1 is repeatedly sent by using different beams for M1 times, assuming that the reference signal set corresponding to the different beams is H, the reference signal with the largest RSRP in the set H can be selected to correspond to the PRACH power as the reference power, and the reference power values are used as the PRACH sending power in the direction when Msg1 in other directions is transmitted.

Or when Msg1 is repeatedly transmitted by using different beams for M1 times, assuming that the reference signal set corresponding to the different beams is H, the PRACH power corresponding to the reference signal with the minimum RSRP in the set H can be selected as the reference power, and the reference power value is used as the PRACH transmission power in the direction of the Msg1 in other directions during transmission.

Or when Msg1 is repeatedly transmitted by using different beams for M1 times, assuming that the reference signal set corresponding to the different beams is H, the PRACH power corresponding to the reference signal with the smallest reference signal index number in the set H can be selected as the reference power, and the reference power value is used as the PRACH transmission power in the direction of the Msg1 in other directions during transmission.

Or when Msg1 is repeatedly transmitted by using different beams for M1 times, assuming that the reference signal set corresponding to the different beams is H, the reference signal with the largest reference signal index number in the set H can be selected to correspond to PRACH power as reference power, and the reference power value is used as the PRACH transmission power in the direction of the Msg1 in other directions during transmission.
