All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The embodiment of the application provides a signal processing method and device, which are used for improving the success rate of random access.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Referring to fig. 1, fig. 1 is a flowchart of a signal processing method provided in an embodiment of the present application, as shown in fig. 1, including the following steps:

step 101, a terminal determines to receive random access feedback information sent by a network device at a resource position corresponding to one or more target DL reference signals;

wherein the random access feedback information includes: RAR, and/or MSGB.

In embodiments of the present application, the terminal may determine one or more target DL reference signals by one or more of:

(1) The terminal receives a first indication sent by the network equipment, and takes a DL reference signal indicated by the first indication as the target DL reference signal.

That is, the terminal determines the target DL reference signal according to an instruction of the network device.

Optionally, in an embodiment of the present application, the DL reference signal indicated by the first indication belongs to a second target DL reference signal packet. The network device determines the target DL reference signal from the second target DL reference signal packet, and sends the information of the packet to which the target DL reference signal belongs, that is, the information of the second target DL reference signal packet, to the terminal through the first indication. Wherein, the information of the second target DL reference signal packet may be a packet identification or the like.

(2) The terminal selects the target DL reference signal from one or more candidate DL reference signals, wherein the signal quality of the target DL reference signal meets the preset requirement.

The signal quality meets a preset requirement, and the signal quality is ranked at the front or the highest.

For example, the terminal may measure the candidate DL reference signals and select one or more DL reference signals having the strongest signal quality as the target DL reference signals therein according to the measurement result.

(3) The terminal selects a first target DL reference signal group according to the channel quality, and takes a DL reference signal in the first target DL reference signal group as the target DL reference signal.

For example, a terminal may select a DL reference signal packet having a better channel quality from among a plurality of candidate DL reference signal packets as a first target DL reference signal packet therein, and use a DL reference signal in the first target DL reference signal packet as the target DL reference signal.

(4) And the terminal determines the target DL reference signal according to the search space or the CORESET or the DL reference signal corresponding to the repeated transmission times of the Preamble or the MSGA.

Specifically, the terminal determines the target DL reference signal according to the first corresponding relation and the second corresponding relation;

For example, for the number of repeated transmissions of a Preamble or MSGA, the corresponding target search space or CORESET may be determined according to the first correspondence; and then, determining the DL reference signal or the DL reference signal group corresponding to the target search space or the CORESET according to the second corresponding relation. And further, one or more DL reference signals of the DL reference signal or DL reference signal packet are regarded as target DL reference signals.

(5) And determining the target DL reference signal according to the MSGA information.

For example, the target DL reference signal may be determined according to a configuration of the MSGA; alternatively, the target DL reference signal is determined according to the transmission order of the MSGA.

The configuration of the MSGA may include, for example, configuration information of the MSGA PUSCH, such as the MSGA PUSCH frequency domain location, MCS (Modulation and coding scheme ) information, and the like. For example, the configuration of the MSGA may have a certain correspondence with the target DL reference signal. After the network device indicates the configuration of the MSGA, the terminal may determine the target DL reference signal according to the correspondence.

When determining the target DL reference signal according to the transmission order of the MSGA, the DL reference signal corresponding to the MSGA is set as the target DL reference signal according to the transmission order of the MSGA.

Upon receiving random access feedback information of a network device, the terminal may receive in one or more of the following manners:

(1) The terminal takes the sum of interception durations of one or more target DL reference signals as a cycle period, and intercepts the random access feedback information in the interception duration of each target DL reference signal in the one or more target DL reference signals in turn according to a target sequence. Wherein, the target sequence is the sequence of sending the Preamble.

That is, in this manner, the terminal receives random access feedback information in a periodic manner. Taking RAR as an example of the random access feedback information, assuming that the number of repeated transmission times of the Preamble is M, DL reference signals corresponding to the transmitted Preamble are respectively a target DL reference signal 0, target DL reference signals 1 and …, and a target DL reference signal (M-1). After the terminal sends the Preamble, opening an RAR window, wherein the length of the RAR window is M×winLen. The terminal listens for RAR under a plurality of target DL reference signals, wherein the interception duration of the target DL reference signal 0 is wilLen 0, the interception duration of the target DL reference signal 1 is wilLen 1 and …, and the interception duration of the target DL reference signal M is wilLennM. That is, in the above procedure, the terminal loops in the order of the target DL reference signal 0 to the target DL reference signal M until the maximum RAR window length is reached. If the RAR is detected within any window, the terminal will consider to be successfully receiving the RAR.

Wherein, winLen is the interception duration of each target DL reference signal, or winLen is the average value of interception durations of a plurality of target DL reference signals. The length of the winLen0 … … winLen1 may be equal, both are winLen, or the length of the winLen0 … … winLen1 are different.

Wherein, the RAR window length may be DL reference signal duration; alternatively, there may be a sum of DL reference signal and DL reference signal transfer time interval length, where DL reference signal transfer time may be understood as the time from the reception transfer of DL reference signal M to the reception of DL reference signal N. The DL reference signals M and N may be two adjacent DL reference signals.

(2) The terminal monitors the random access feedback information in turn within the monitoring duration of each target DL reference signal in the one or more target DL reference signals according to the target sequence and the repeated transmission times of the Preamble on each target DL reference signal in the one or more target DL reference signals, wherein the monitoring duration of each target DL reference signal is the product of the repeated transmission times of the Preamble on each target DL reference signal and the monitoring duration on each target DL reference signal.

Wherein, the target sequence is the sequence of sending the Preamble. Taking RAR as an example of random access feedback information, assuming that P Preamble is sent on RO resource corresponding to the target DL reference signal 1 and Q Preamble is sent on RO resource corresponding to the target DL reference signal 2, the interception duration of the terminal on the target DL reference signal 1 is windlen×p, and the interception duration of the terminal on the target DL reference signal 2 is windlen×q. The windLen represents the listening period of each target DL reference signal.

(3) And the terminal receives the random access feedback information at a resource position corresponding to the target DL reference signal with the target index number or the target DL reference signal with the best signal quality in the first target DL reference signal packet.

Wherein the target index number may be specified by the network device.

(4) And the terminal monitors the random access feedback information in the monitoring duration of each target DL reference signal in the one or more target DL reference signals in turn according to the target sequence.

Wherein, the target sequence is the sequence of sending the Preamble. Taking RAR as an example of the random access feedback information, assuming that the number of repeated transmission times of the Preamble is M, DL reference signals corresponding to the transmitted Preamble are respectively a target DL reference signal 0, target DL reference signals 1 and …, and a target DL reference signal (M-1). After the terminal sends the Preamble, opening an RAR window, wherein the length of the RAR window is M×winLen. The terminal listens for RAR under a plurality of target DL reference signals, wherein the interception duration of the target DL reference signal 0 is wilLen 0, the interception duration of the target DL reference signal 1 is wilLen 1 and …, and the interception duration of the target DL reference signal M is wilLennM.

Wherein, the RAR window length may be DL reference signal duration; alternatively, there may be a sum of DL reference signal and DL reference signal reception time interval length, where DL reference signal reception time may be understood as a time taken for the reception of DL reference signal M to shift to reception of DL reference signal N. The DL reference signals M and N may be two adjacent DL reference signals.

(5) And the terminal receives the random access feedback information at a resource position corresponding to the target DL reference signal according to a search space or CORESET corresponding to the repeated transmission times of the Preamble and the corresponding relation between the repeated transmission times of the Preamble and RO resources.

The correspondence between the search space corresponding to the number of repeated transmissions of the Preamble or the number of repeated transmissions of CORESET, preamble and the RO resource may be indicated by the network device. For example, after obtaining the search space or CORESET information, the terminal may determine the corresponding RO according to the above information, and further receive the random access feedback information at the resource location of the corresponding target DL reference signal.

Optionally, if the random access feedback information is MSGB, the terminal may receive the MSGB by one or more of the following manners:

(1) And the terminal receives the MSGB by utilizing a target DL reference signal corresponding to the MSGA according to the configuration information of the MSGA.

The configuration information of the MSGA may include a correspondence between the MSGA and a DL reference signal. If the terminal receives the MSGA, the terminal can determine the corresponding target DL reference signal according to the MSGA received by the terminal and the corresponding relation, and then receive the MSGB.

(2) And the terminal receives the MSGB in a listening window of a target DL reference signal corresponding to the MSGA according to the sending sequence of the MSGA.

That is, the terminal sequentially receives the MSGB within the listening window of the target DL reference signal corresponding to the MSGA in the transmission order of the MSGA.

On the basis of the above embodiment, the terminal may further send a Preamble or MSGA on a PRACH resource corresponding to the target DL reference signal.

Specifically, the terminal orders the one or more target DL reference signals according to the order of the signal quality of the one or more target DL reference signals from high to low, obtains an ordering result, and sends a Preamble or MSGA on PRACH resources corresponding to the one or more target DL reference signals according to the ordering result.

Optionally, the method further comprises: the terminal receives the configuration parameters sent by the network equipment and determines random access parameters according to the configuration parameters.

Wherein the configuration parameters include one or more of the following:

number of repeated transmissions of Preamble or MSGA: for example, 1,2,4,8, 16; wherein 1 represents that Preamble is sent once on RPACH resource, 2 represents that Preamble is repeatedly sent 2 times on PRACH resource;

a second indication, configured to indicate whether to allow the terminal to select multiple SSBs to send the Preamble, i.e. whether to allow the terminal to transmit the Preamble across beams;

correspondence between Preamble index range and Preamble repetition transmission times: for example, preamble index 0-4 corresponds to the number of repeated transmissions 1,Preamble index 5-8 corresponds to the number of repeated transmissions 2, …, preamble index n-m corresponds to the number of repeated transmissions L, etc.;

information of DL reference signal packet: for example, DL reference signal 0/1 belongs to DL reference signal packet 1, DL reference signal 2/3 belongs to packet 2, etc.;

information of DL reference signal: the signal can be SSB or CSI-RS (CSI Reference Signal ), DL reference signal period, beam information corresponding to the DL reference signal, the corresponding relation between the DL reference signal and the Preamble repeated transmission times, and the like; for example, when the Preamble repetition transmission number is set to 1, the index number corresponding to the DL reference signal is 0, and when the Preamble repetition transmission number is set to 2, the index number corresponding to the DL reference signal is 0,2;

Correspondence between the number of repeated transmissions of Preamble or MSGA and search space or CORESET or DL reference signal: alternatively, the search space or CORESET or DL reference signal corresponding to the number of repeated transmissions of multiple preambles or MSGA may be the same. For example, the search space corresponding to Preamble repeat transmission times of 1 is SearchSpace1, CORESET is CORESET1, and so on.

Wherein the explanation of each of the configuration parameters may be referred to the description of the previous embodiments.

(2) Determining a first RSRP threshold of the Preamble repeated transmission times;

(3) Whether the terminal is allowed to select a plurality of SSBs to send a second indication of the Preamble, namely whether the terminal is allowed to transmit the indication information of the Preamble across beams.

Step 306, the terminal receives the RAR at the resource location corresponding to the target DL reference signal.

Optionally, the terminal receives the RAR in a periodic manner. For example, the number of repeated transmissions of the Preamble is M, and DL reference signals corresponding to the transmitted Preamble are respectively the target DL reference signal 0, the target DL reference signals 1 and …, and the target DL reference signal (M-1). After sending the Preamble, the terminal opens the RAR window, where the RAR window length is m×winlen. The terminal listens for RAR under a plurality of reference signals, wherein the interception duration of the target DL reference signal 0 is winLen0, the interception duration of the target DL reference signal 1 is winLen1 and …, and the interception duration of the target DL reference signal M is winLennM.
