Detailed Description
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.
FIG. 1 is a flow chart of a method according to one embodiment of the invention. As shown, one embodiment of the present invention has the steps of:
Step 11: the base station sends configuration of a PUSCH resource set used for carrying uplink control information to the mobile terminal through RRC signaling, wherein the PUSCH resource set used for carrying the uplink control information comprises a time slot in a time domain and a first frequency band in a frequency domain, and the first frequency band comprises a plurality of resource block sets; in one embodiment, the configuration of the PUSCH resource set for carrying uplink control information includes configuration information of the PUSCH resource set, e.g. the configuration of the PUSCH resource set for carrying uplink control information signals to the mobile terminal that the PUSCH resource set for carrying uplink control information has a length of one slot and has frequency resources of a certain width; in one embodiment, the configuration of the PUSCH resource set for carrying uplink control information indicates to the mobile terminal that the PUSCH resource set for carrying uplink control information has a frequency resource of a total of 50 RBs (in a 5G context, one RB may refer to a resource grid comprising 12 subcarriers) and indicates a starting frequency of the frequency resource, and indicates how the 50 RBs are divided into a plurality of resource block sets; in one embodiment, 50 RBs may be indicated to be divided into 5 sets of resource bins, with a first set of resource bins including ten resource bins numbered 0-9, a second set of resource bins including ten resource bins numbered 10-19, and so on; in one embodiment, the configuration of PUSCH resource sets for carrying uplink control information indicates multiple symbol sets in one slot to the mobile terminal, in one embodiment, one slot of the 5G system has 14 symbols, one slot first three or two symbols may be control channels, PUSCH channels occupy 11 symbols or 12 symbols respectively, PUSCH channels occupy 12 symbols as an example (in this example, symbols numbered 0-1 are control channel symbols), the configuration of PUSCH resource sets for carrying uplink control information indicates that the 12 symbols are divided into, for example, four sets, the first symbol set is three symbols numbered 2-4, the second symbol set is three symbols numbered 5-7, the third symbol set is three symbols numbered 8-10, and the fourth symbol set is three symbols numbered 11-13;
Step 12: after sending a PUSCH resource set for carrying uplink control information to the mobile terminal, the base station monitors a PUSCH signal sent by the mobile terminal in a time slot and on a first frequency band; in one embodiment, if a PUSCH resource set related to a configuration instruction of a PUSCH resource set for carrying uplink control information, which is sent by a base station to a mobile terminal, has a time slot length and a frequency range including a first frequency band, the base station monitors a PUSCH signal sent by the mobile terminal to the base station in a certain time slot and the first frequency band; in one embodiment, if the base station determines, based on its scheduling history, that the mobile terminal will transmit a PUSCH signal to the base station in a certain time slot and the first frequency band after a period of time, the base station may wait for a corresponding PUSCH signal transmitted by the mobile terminal after the period of time; in one embodiment, if the base station does not wish to wait for the aforementioned period of time, the base station may schedule the mobile terminal to immediately send a PUSCH signal to the base station in the next slot and the first frequency band by sending a PDCCH message; in one embodiment, if the mobile terminal determines that the mobile terminal has no data to transmit after receiving the schedule that the base station requires the PUSCH signal to be transmitted to the base station immediately in the next slot and the first frequency band, the mobile terminal may transmit a segment of padding bits (e.g., all 1 bits) to the base station.
Step 13: after monitoring a PUSCH signal transmitted by a mobile terminal on a first frequency band, a base station determines a signal reception strength of a signal received on each set of resource blocks in the first frequency band; in one embodiment, the signal reception strength may be a signal to noise ratio; in one embodiment, if the PUSCH resource set allocated by the base station to the mobile terminal for carrying uplink control information includes 50 RBs and the 50 RBs are divided into 5 resource grid sets, the base station determines the signal-to-noise ratio of the signal received on a first resource grid set of ten resource grids numbered 0-9 (e.g., number 1) (and over the entire slot), a second resource grid set of ten resource grids numbered 10-19 (e.g., number 2), a third resource grid set of ten resource grids numbered 20-29 (e.g., number 3), a fourth resource grid set of ten resource grids numbered 30-39 (e.g., number 4), and a fifth resource grid set of ten resource grids numbered 40-49 (e.g., number 5), respectively;
Step 14: after monitoring a PUSCH signal transmitted by a mobile terminal on a first frequency band, a base station determines signal reception strengths of signals received over a plurality of time periods in a slot; in one embodiment, if the base station assigns the mobile terminal three symbols numbered 2-4 (numbered 1), the second set of symbols is three symbols numbered 5-7 (numbered 2), the third set of symbols is three symbols numbered 8-10 (numbered 3), and the fourth set of symbols is three symbols numbered 11-13 (numbered 4), then the base station determines the signal-to-noise ratio of the signal received by the three symbols numbered 2-4 (and the entire first frequency band), the signal-to-noise ratio of the signal received by the three symbols numbered 5-7, the signal-to-noise ratio of the signal received by the three symbols numbered 8-10, and the signal-to-noise ratio of the signal received by the three symbols numbered 11-13;
Step 15: based on the signal reception strengths of the signals received on each set of resource blocks in the first frequency band and the signal reception strengths of the signals received over a plurality of time periods in the time slot, the base station determines priorities of the set of resource blocks and the set of symbols; in one embodiment, the priority may be represented by the following list:
In this embodiment, the resource block set 1 is not paired with the symbol set, but if a subcarrier interval of 7.5KHz is selected, the time slot length at the subcarrier interval of 7.5KHz will be doubled compared with the time slot length at the subcarrier interval of 15KHz, the duration of each OFDM symbol is doubled, and when one symbol set may only include two symbols, then there may be at least 6 symbol sets in one time slot, and when the resource block set 1 has paired symbol sets, in short, the currently available resource block sets bring scalability to the system.
Step 16: after determining the priorities of the resource block set and the symbol set, the base station transmits downlink control information a to the mobile terminal, wherein the downlink control information a indicates PUSCH resource a to the mobile terminal, wherein the PUSCH resource a includes a time slot a in a time domain and includes a first frequency band in a frequency domain, and wherein the downlink control information a has a priority list of the resource block set and the symbol set. In a preferred embodiment, the effective time of the priority list with the resource block set and the symbol set in the downlink control information a lasts at least 10 time slots, that is, the base station only needs to send the downlink control information a and the priority list once in the first time slot, and then the base station only needs to resend the downlink control information a and the priority list once in the eleventh time slot;
In a preferred embodiment, the set of resource blocks a in the first frequency band has a higher priority if the signal reception strength of the signal received on the set of resource blocks a in the first frequency band is higher;
Symbol set a has a higher priority if the signal reception strength of the signal received on symbol set a in the slot is greater. In my research, my researchers found that, based on the cause of frequency selective fading, signal quality in a certain frequency range persisted worse over a period of time, and signal quality in a certain frequency range persisted stronger; meanwhile, in my research, especially for mobile terminals with low mobility (such as quasi-stationary state or mobile terminals moving at walking speed), my discovery that signal fading has a certain time periodicity, especially 3-6 symbols with poor signal in one slot, and in the next or later n slots, the signal quality on the 3-6 symbols may be equally poor, and this periodicity may be related to the complex signal scattering factors that are prevalent in the environment;
In a preferred embodiment, the mobile terminal, after receiving the downlink control information a, determines a priority of each set of resource blocks in the first frequency band and a priority of each set of symbols in the slot a based on the set of resource blocks and the priority list of the set of symbols;
The mobile terminal determines a resource block set B with the highest priority and a symbol set B with the highest priority; based on the foregoing specific embodiment, the resource block set B with the highest priority is the resource block set No. 3, and the symbol set B with the highest priority is the symbol set No. 3;
After determining the resource block set B and the symbol set B, the mobile terminal determines whether the resource block set B and the symbol set B are available; in one embodiment, if after receiving the downlink control information a, the mobile terminal receives a pre-emption indicator (pre-emption indication) sent by the base station before sending an acknowledgement/negative acknowledgement message using the resource block set B and the symbol set B, and the pre-emption indicator indicates that the resource block set B and the symbol set B are allocated to other URLLC mobile terminals for use, then the resource block set B and the symbol set B may be considered as unavailable;
If it is determined that the resource block set B and the symbol set B are available, the mobile terminal transmits an acknowledgement/negative acknowledgement message to the base station on the resource block set B and the symbol set B;
If it is determined that the resource block set B and the symbol set B are not available, the mobile terminal determines the resource block set C having the next highest priority and the symbol set C having the next highest priority (in the foregoing specific embodiment, the resource block set C having the next highest priority is the resource block set of number 4 and the symbol set C having the next highest priority is the symbol set of number 2). It should be understood by those skilled in the art that in the case of determining that the resource block set B and the symbol set B are not available, the mobile terminal determines the resource block set C with the next highest priority and the symbol set C with the next highest priority, and then the mobile terminal should continue to determine whether the resource block set C and the symbol set C are available again according to the method described in the present application, and if so, the mobile terminal sends ACK and NACK messages to the base station on the resource block set C and the symbol set C; if all sets are determined to be unavailable in order of priority (e.g., all resources are preempted), the mobile terminal does not send UCI messages to the base station.
In a preferred embodiment, after sending an acknowledgement/negative acknowledgement message to the base station on the set of resource blocks B and the set of symbols B, the mobile terminal determines the set of resource blocks C with the next highest priority and the set of symbols C with the next highest priority; in one embodiment, the mobile terminal may of course select the set of resource blocks B with the highest priority and the set of symbols B with the highest priority first, then select the set of resource blocks C with the next highest (i.e. the second highest) priority and the set of symbols B with the highest priority, then select the set of resource blocks B with the highest priority and the set of symbols C with the next highest priority, then select the set of resource blocks C with the next highest priority and the set of symbols C with the next highest priority, but this approach may lead to a lengthy mobile terminal judgment procedure, increased power consumption, while the larger the number of resources the mobile terminal may use, the smaller the base station scheduling flexibility. For example, in the foregoing manner, the mobile terminal may send UCI in four manners (a set of resource blocks, a set of symbols) (B, B), (B, C), (C, B), (C, C), and then when the base station wants to preempt resources, for example, it evaluates URLLC UE whether to send data on (B, B), (B, C), (C, B), (C, C) respectively, whether the symbol URLLC delay and the reliability budget are evaluated, and if the delay and the reliability budget meet the requirements, the base station then evaluates URLLC UE whether the priority of sending data on (B, B) is higher than the priority of sending UCI on (B, B) by the mobile terminal. According to the method of the application, the resource combination of (B, C) and (C, B) is idle, so long as the base station evaluates URLLC UE that the time delay and the reliability budget for transmitting on the resource combination of (B, C) and (C, B) meet the requirements, the base station can execute the allocation, and the operation ensures that the time delay when the base station allocates the resource has a certain gain;
After determining the resource block set C and the symbol set C, the mobile terminal determines whether the resource block set C and the symbol set C are available;
If the resource block set C and the symbol set C are determined to be available, the mobile terminal sends a rank indicator to the base station on the resource block set C and the symbol set C;
After transmitting the rank indicator to the base station on the resource block set C and the symbol set C, the mobile terminal determines a resource block set D with a third highest priority and a symbol set D with a third highest priority;
after determining the resource block set D and the symbol set D, the mobile terminal determines whether the resource block set D and the symbol set D are available;
If it is determined that the set of resource blocks D and the set of symbols D are available, the mobile terminal transmits a portion of the channel quality indicator to the base station on the set of resource blocks D and the set of symbols D;
after transmitting a portion of the channel quality indicator to the base station on the set of resource blocks D and the set of symbols D, the mobile terminal determines a set of resource blocks E having a fourth highest priority and a set of symbols E having a fourth highest priority;
after determining the resource block set E and the symbol set E, the mobile terminal determines whether the resource block set E and the symbol set E are available;
if it is determined that the set of resource blocks E and the set of symbols E are available, the mobile terminal transmits another portion of the channel quality indicator to the base station on the set of resource blocks E and the set of symbols E.
FIG. 2 is a flow chart of a method according to one embodiment of the invention. As shown, one embodiment of the present invention has the steps of:
step 21: the base station sends configuration of a PUSCH resource set used for carrying uplink control information to the mobile terminal through RRC signaling, wherein the PUSCH resource set used for carrying the uplink control information comprises a time slot in a time domain and a first frequency band in a frequency domain, and the first frequency band comprises a plurality of resource block sets;
Step 22: after sending a PUSCH resource set for carrying uplink control information to the mobile terminal, the base station monitors a PUSCH signal sent by the mobile terminal in a time slot and on a first frequency band;

Step 24: after monitoring a PUSCH signal transmitted by a mobile terminal on a first frequency band, a base station determines signal reception strengths of signals received over a plurality of time periods in a slot;
Step 25: based on the signal reception strengths of the signals received on each set of resource blocks in the first frequency band and the signal reception strengths of the signals received over a plurality of time periods in the time slot, the base station determines priorities of the set of resource blocks and the set of symbols;
step 26: after determining the priorities of the resource block sets and the symbol sets, the base station transmits downlink control information B to the mobile terminal, wherein the downlink control information B indicates PUSCH resources a to the mobile terminal, wherein the PUSCH resources a include a time slot a in a time domain and a first frequency band in a frequency domain, wherein the downlink control information B has a priority list of the resource block sets and the symbol sets, and wherein the downlink control information B has an availability indicator of the resource block sets and the symbol sets. In one embodiment, the relevant messages are indicated in the following manner,
In a preferred embodiment, the set of resource blocks a in the first frequency band has a higher priority if the signal reception strength of the signal received on the set of resource blocks a in the first frequency band is higher;
Symbol set a has a higher priority if the signal reception strength of the signal received on symbol set a in the slot is greater.
